The circular ring sleeve 15 is fixed at the end of the sliding rod 10 movably passing through the fixed sleeve 8, and the circular ring sleeve 15 is spirally wound with a movable conductive coil 16. The ring sleeve 15 is used to connect the external metal plate 18 of the external object; the two ends of the moving conductive coil 16 are respectively connected to the two conductive plates 6 in another group of conductive plates, and one end of the moving conductive coil 16 is connected to the connected conductive plate 6. Another DC power source 4 is connected in series between the boards 6 .

固定导电线圈9和移动导电线圈16螺旋绕制方向相同,电流方向相反。具体实施中,两个直流电源4的正负极布置方向相反,使得分别连接到固定导电线圈9和移动导电线圈16一端的电极极性相反,进而使得固定导电线圈9和移动导电线圈16的电流方向相反。The fixed conductive coil 9 and the movable conductive coil 16 are spirally wound in the same direction, and the current directions are opposite. In the specific implementation, the positive and negative electrodes of the two DC power sources 4 are arranged in opposite directions, so that the electrodes connected to one end of the fixed conductive coil 9 and the moving conductive coil 16 respectively have opposite polarities, so that the currents of the fixed conductive coil 9 and the moving conductive coil 16 are reversed. In the opposite direction.

外部物体为外部金属板18,当外部物体18撞击接触时,外部金属板18和圆环套15接触连接。外部金属板是外部物体,可以代指电梯的某个部件。以电梯为例,本发明装置可以固定在楼房底部,并不是跟随电梯运动,只是到哪个电梯掉落时,外部金属板18才会撞击本装置,从而使本装置起保护作用。The external object is the external metal plate 18 , and when the external object 18 strikes and contacts, the external metal plate 18 and the annular sleeve 15 are in contact and connected. An external metal plate is an external object that can refer to a component of an elevator. Taking an elevator as an example, the device of the present invention can be fixed at the bottom of a building, and does not move with the elevator, but only when the elevator falls, the outer metal plate 18 will hit the device, so that the device plays a protective role.

移动导电线圈16所连接的导电板组相比固定导电线圈9所连接的导电板组更靠近钢丝绳17和动滑轮11布置。The conductive plate group connected to the moving conductive coil 16 is arranged closer to the wire rope 17 and the movable pulley 11 than the conductive plate group connected to the fixed conductive coil 9 .

电阻组件是由多个同心布置的电阻板13构成,多个电阻板13间隔固定套装在滑动杆10上,电阻板13位于两组导电板组的两个导电板6之间,电阻组件中至少一个电阻板13两侧分别电连接到固定导电线圈9所连接的一组导电板组的两个导电板6上,使得两个导电板6相导通。相邻电阻板13绝缘。The resistance assembly is composed of a plurality of concentrically arranged resistance plates 13, the plurality of resistance plates 13 are fixedly sleeved on the sliding rod 10 at intervals, and the resistance plates 13 are located between the two conductive plates 6 of the two groups of conductive plates. Two sides of a resistance plate 13 are electrically connected to two conductive plates 6 of a group of conductive plates connected to the fixed conductive coil 9 respectively, so that the two conductive plates 6 are connected to each other. Adjacent resistive plates 13 are insulated.

多个电阻板13整体沿滑动杆10轴向的长度大于一组导电板组的两个导电板6沿滑动杆10轴向的长度,且小于一组导电板组的两个导电板6沿滑动杆10轴向的长度的两倍与两组导电板6间隙之和。The overall length of the plurality of resistance plates 13 along the axial direction of the sliding rod 10 is greater than the length of the two conductive plates 6 of a group of conductive plates along the axial direction of the sliding rod 10, and is smaller than the length of the two conductive plates 6 of a group of conductive plates along the sliding rod 10. Twice the axial length of the rod 10 and the sum of the gap between the two groups of conductive plates 6 .

滑动杆10活动穿设固定套8地轴向移动,带动滑动杆10上固定的电阻组件同步移动,调整两组组导电板组中两个导电板6之间所连接导通的电阻板13数量,即调节两组组导电板组中两个导电板6之间所连接导通的电阻组件的阻值,进而调节在固定导电线圈9和移动导电线圈16产生的导通电流,即调节固定导电线圈9和移动导电线圈16所产生的磁场,实现固定模块2和移动模块3之间的相互变阻力排斥运动。The sliding rod 10 moves axially through the fixed sleeve 8, which drives the resistance components fixed on the sliding rod 10 to move synchronously, and adjusts the number of conductive resistance plates 13 connected between the two conductive plates 6 in the two groups of conductive plates. , that is, to adjust the resistance value of the conductive resistance components connected between the two conductive plates 6 in the two groups of conductive plates, and then to adjust the conduction current generated by the fixed conductive coil 9 and the moving conductive coil 16, that is, to adjust the fixed conductive The magnetic field generated by the coil 9 and the moving conductive coil 16 realizes the mutually variable resistance repulsion motion between the fixed module 2 and the moving module 3 .

由此,当出现外部撞击带动移动模块做放松钢丝绳运动时,移动模块和固定模块的两个电磁铁通过电阻改变实现阻力改变,从而实现变阻力减震效果。同时,移动模块的滑动,实现了钢丝绳的卸载。Therefore, when an external impact drives the mobile module to loosen the wire rope, the two electromagnets of the mobile module and the fixed module realize resistance changes through resistance changes, thereby realizing the variable resistance shock absorption effect. At the same time, the sliding of the mobile module realizes the unloading of the wire rope.

具体实施中,电阻板的数量为9个,且每个电阻板的尺寸与电阻值均相等。四个电阻板13整体沿滑动杆10轴向的长度等于一组导电板组的两个导电板6沿滑动杆10轴向的长度,两组导电板组之间沿滑动杆10轴向的间隔长度大于一个电阻板13整体沿滑动杆10轴向的长度。In a specific implementation, the number of resistance plates is 9, and the size and resistance value of each resistance plate are equal. The overall length of the four resistance plates 13 along the axial direction of the sliding rod 10 is equal to the length of the two conductive plates 6 of one set of conductive plate groups along the axial direction of the sliding rod 10, and the interval between the two groups of conductive plate groups along the axial direction of the sliding rod 10 The length is greater than the entire length of one resistance plate 13 along the axial direction of the sliding rod 10 .

固定电磁铁5是由固定导电线圈9缠绕在固定套8上组成,固定套8中心处设计有一个用于滑动杆10穿过的方形通孔。固定电磁铁5与移动电磁铁14的线圈绕线方向一致,电流方向相反。The fixed electromagnet 5 is composed of a fixed conductive coil 9 wound on a fixed sleeve 8 , and a square through hole for the sliding rod 10 to pass through is designed at the center of the fixed sleeve 8 . The winding directions of the coils of the fixed electromagnet 5 and the moving electromagnet 14 are the same, and the current directions are opposite.

滑动杆10的材质为绝缘材质,形状为方形长杆,其方形截面的尺寸与固定套8中心处的方形通孔尺寸一致。滑动杆10中部设置有格栅状结构,格栅间隙为九个,尺寸恰好安装九个电阻板。The material of the sliding rod 10 is insulating material, and the shape is a square long rod. The middle of the sliding rod 10 is provided with a grid-like structure, and there are nine grid gaps, and the size is exactly nine resistance plates.

每组中两个导电板的间隔垂直距离等于电阻板的宽度。两组导电板的间距大于一片电阻板的厚度。导电板的长度等于四片电阻板的厚度与3个格栅间隙之和。The two conductive plates in each group are separated by a vertical distance equal to the width of the resistive plates. The distance between the two groups of conductive plates is greater than the thickness of one resistance plate. The length of the conductive plate is equal to the sum of the thickness of the four resistance plates and the three grid gaps.

当移动模块处于拉紧钢丝绳17的极限位置时,只有仅最靠近钢丝绳17的一片电阻板连通移动导电线圈16所连接的导电板6,远离钢丝绳17一侧的四片电阻板连通固定导电线圈9所连接的导电板;When the mobile module is in the limit position of tightening the steel wire rope 17, only the resistance plate closest to the steel wire rope 17 is connected to the conductive plate 6 connected to the moving conductive coil 16, and the four resistance plates on the side away from the wire rope 17 are connected to the fixed conductive coil 9. The connected conductive plate;

当移动模块处于卸载放松钢丝绳17的极限位置时,只有靠近钢丝绳17的四片电阻板连通移动导电线圈16所连接的导电板6,无远离钢丝绳17一侧的电阻板连通固定导电线圈9所连接的导电板。此时,固定导电线圈9没有通电,没有产生磁场,固定导电线圈9和移动导电线圈16之间没有产生排斥力,使得移动模块不会反弹。When the mobile module is in the limit position of unloading and loosening the wire rope 17, only the four resistance plates close to the wire rope 17 are connected to the conductive plate 6 connected to the moving conductive coil 16, and no resistance plate far from the wire rope 17 is connected to the fixed conductive coil 9. conductive plate. At this time, the fixed conductive coil 9 is not energized, no magnetic field is generated, and no repulsive force is generated between the fixed conductive coil 9 and the movable conductive coil 16, so that the mobile module will not bounce.

具体实施的卸载和变阻力减震结构1的安装方式如下:The specific implementation of the unloading and variable resistance shock absorbing structure 1 is as follows:

固定模块2作为固定端,移动模块3套入到固定模块2中装配。The fixed module 2 is used as the fixed end, and the moving module 3 is inserted into the fixed module 2 for assembly.

其中,固定模块2中的导电板6共有4块,分别编号为M/U/K/P(图4)。其中电磁板M与电磁板P对称安装,M连接直流电源4的负极,P首先连接到移动电磁铁14的导电线圈16上,然后连接到直流电源4的正极(图7、图4);电磁板U与电磁板K对称安装,U连接到直流电源4的正极,K首先连接到固定电磁铁5的导电线圈9,然后连接到直流电源4的负极(图7、图4)。卡扣支架7用于固定导电板6(图4)。Among them, there are 4 conductive plates 6 in the fixed module 2, which are respectively numbered as M/U/K/P (FIG. 4). The electromagnetic plate M is installed symmetrically with the electromagnetic plate P, M is connected to the negative pole of the DC power supply 4, P is first connected to the conductive coil 16 of the moving electromagnet 14, and then connected to the positive pole of the DC power supply 4 (Figure 7, Figure 4); The plate U is installed symmetrically with the electromagnetic plate K, U is connected to the positive pole of the DC power supply 4, and K is first connected to the conductive coil 9 of the fixed electromagnet 5, and then connected to the negative pole of the DC power supply 4 (Figure 7, Figure 4). The snap bracket 7 is used to fix the conductive plate 6 (FIG. 4).

其中,移动模块3中滑动杆10两端分别锁固移动电磁铁14和动滑轮11(图6).滑动杆10中部位置间隔安装9片电阻板13(图6)。移动模块3安装在固定模块2的对称中心上.具体的,移动模块3的滑动杆10套入固定模块2的固定电磁铁5的固定套8的方孔内,移动模块3可以相对于固定模块2的滑动。Wherein, the two ends of the sliding rod 10 in the mobile module 3 are respectively locked to the movable electromagnet 14 and the movable pulley 11 (FIG. 6). The middle position of the sliding rod 10 is installed with 9 resistance plates 13 (FIG. 6). The mobile module 3 is installed on the symmetrical center of the fixed module 2. Specifically, the sliding rod 10 of the mobile module 3 is inserted into the square hole of the fixed sleeve 8 of the fixed electromagnet 5 of the fixed module 2, and the mobile module 3 can be relative to the fixed module. 2 slides.

特别的,固定电磁铁5是由导电线圈9缠绕在固定套8上组成,其中固定套8中心设计有一个方形通孔(图3),方形通孔起“滑套”的作用,其内部可以贯穿安装移动模块3的滑动杆10,并允许滑动杆10在其方孔内滑动。In particular, the fixed electromagnet 5 is composed of a conductive coil 9 wound on a fixed sleeve 8, wherein a square through hole is designed in the center of the fixed sleeve 8 (Fig. 3), and the square through hole acts as a "sliding sleeve". The sliding rod 10 of the mobile module 3 is installed therethrough, and the sliding rod 10 is allowed to slide in its square hole.

特别的,滑动杆10中间局部为格栅状,作用是:卡固安装9片电阻板13(图6)。In particular, the middle part of the sliding rod 10 is in the shape of a grid, and the function is to clamp and install nine resistance boards 13 (FIG. 6).

特别的,滑动杆10是硬质绝缘的,且滑动杆的截面为方形,截面尺寸(不包括格栅截面)等于固定套8的方形通孔尺寸,既防止滑动杆10转动,又可以实现滑动杆10在固定套8的方孔内滑动。In particular, the sliding rod 10 is rigidly insulated, and the section of the sliding rod is square, and the cross-sectional size (excluding the grille section) is equal to the size of the square through hole of the fixing sleeve 8, which not only prevents the sliding rod 10 from rotating, but also realizes sliding The rod 10 slides in the square hole of the fixed sleeve 8 .

特别的,导电板M与导电板P的间距等于电阻板13的宽度;导电板U与导电板K的间距等于电阻板13的宽度,这样随着移动模块3的滑动,电阻板13恰好可以在两组导电板之间滑动,并在滑动过程中连通导电板M与P,或连通导电板U与K。In particular, the distance between the conductive plate M and the conductive plate P is equal to the width of the resistance plate 13; the distance between the conductive plate U and the conductive plate K is equal to the width of the resistance plate 13, so that with the sliding of the moving module 3, the resistance plate 13 can just be The two groups of conductive plates slide between each other, and during the sliding process, the conductive plates M and P are connected, or the conductive plates U and K are connected.

特别的,两组导电板之间的间隔(即:M与U之间的间隔,或K与P之间的间隔)(图7),小于单片电阻板13的厚度,这样防止同一个电阻板13同时连通两组导电板而造成电路混乱。In particular, the interval between the two groups of conductive plates (ie: the interval between M and U, or the interval between K and P) (FIG. 7) is smaller than the thickness of the single-piece resistance plate 13, thus preventing the same resistance The board 13 is connected to two groups of conductive boards at the same time to cause circuit confusion.

特别的,每个导电板6的长度等于4片电阻板13的厚度与3个格栅间距之和,这样保证同一组导电板6最多只能同时连接4片电阻板13。In particular, the length of each conductive plate 6 is equal to the sum of the thickness of the four resistance plates 13 and the three grid spacings, thus ensuring that the same group of conductive plates 6 can only be connected to four resistance plates 13 at the same time.

特别的,当移动模块3处在右极限位置时(图7),只有一片电阻板13连通导电板M和导电板P;此时有4片电阻板13连通导电板U和导电板K。In particular, when the moving module 3 is at the right limit position (FIG. 7), only one resistive plate 13 connects the conducting plate M and the conducting plate P; at this time, there are four resistive plates 13 connecting the conducting plate U and the conducting plate K.

特别的,当移动模块3处在左极限位置时(图10),移动电磁铁14与固定电磁铁5接触,此时,有4片电阻板13连通导电板M和导电板P,无电阻板13连通导电板U和导电板K(图10)。In particular, when the moving module 3 is at the left limit position (FIG. 10), the moving electromagnet 14 is in contact with the fixed electromagnet 5. At this time, there are 4 resistance plates 13 connecting the conductive plate M and the conductive plate P, and there are no resistance plates. 13 Connect the conductive plate U and the conductive plate K (Fig. 10).

特别的,固定电磁铁5和移动电磁铁14的线圈绕线方向一致,但电流方向相反。这种设计的有益效果是:当两个线圈均通电时,两个电磁铁之间的磁极方向相反,两个电磁铁之间产生斥力。In particular, the winding directions of the coils of the fixed electromagnet 5 and the moving electromagnet 14 are the same, but the current directions are opposite. The beneficial effect of this design is that when both coils are energized, the magnetic poles between the two electromagnets are in opposite directions, and a repulsive force is generated between the two electromagnets.

特别的,每个滑轮均配置一个滑轮挡板12(图6)。滑轮挡板为弧形面结构,弧形面的起始平面与滑轮凹槽的下平面齐平,这种设计的效果是:当钢丝绳17松动时,钢丝绳并不会完全脱离滑轮凹槽的有效范围。当钢丝绳17再次张紧时,钢丝绳可以自动卡入滑轮的凹槽内,并不需要人工调整。In particular, each pulley is provided with a pulley baffle 12 (FIG. 6). The pulley baffle is an arc surface structure, and the starting plane of the arc surface is flush with the lower plane of the pulley groove. The effect of this design is that when the wire rope 17 is loose, the wire rope will not completely escape from the pulley groove. scope. When the wire rope 17 is tensioned again, the wire rope can be automatically snapped into the groove of the pulley without manual adjustment.

变阻力减震原理过程:The principle and process of variable resistance shock absorption:

初始位置时(图7),有1片电阻板13连通导电板M和P,移动电磁铁14形成回路并产生磁力;同时,有4片电阻板13连通导电板U和K,固定电磁铁5形成回路并产生磁力;并且,移动电磁铁14与固定电磁铁5的电流方向相反,因此二者之间形成斥力。在此斥力的作用下,移动电磁铁14带动整个移动模块2向右滑动至右极限位置,尤其是动滑轮11随之向右运行至极限位置(图7)。此时,钢丝绳17在动滑轮11的作用下张紧(图7),此时,钢丝绳处于正常驱动状态。In the initial position (Fig. 7), there is 1 resistance plate 13 connected to the conductive plates M and P, and the moving electromagnet 14 forms a loop and generates a magnetic force; at the same time, there are 4 resistance plates 13 connected to the conductive plates U and K, and the fixed electromagnet 5 A loop is formed and a magnetic force is generated; and the current direction of the moving electromagnet 14 and the fixed electromagnet 5 are opposite, so a repulsive force is formed between the two. Under the action of the repulsive force, the moving electromagnet 14 drives the entire moving module 2 to slide to the right limit position, especially the movable pulley 11 moves to the right limit position ( FIG. 7 ). At this time, the wire rope 17 is tensioned under the action of the movable pulley 11 (FIG. 7), and at this time, the wire rope is in a normal driving state.

当外部金属板18(例如电梯箱体的外部骨架)迅速撞击移动电磁体14的外端面时,移动电磁铁14收到撞击开始左移;与此同时,滑动杆10带动动滑轮11左移,动滑轮11向左移动后,导致钢丝绳17出现松动,从而失去张紧作用,进而实现卸载(图8)。When the outer metal plate 18 (such as the outer frame of the elevator box) rapidly hits the outer end face of the moving electromagnet 14, the moving electromagnet 14 receives the impact and starts to move left; at the same time, the sliding rod 10 drives the moving pulley 11 to move left, and the moving pulley After 11 moves to the left, the wire rope 17 is loosened, so that the tensioning effect is lost, and the unloading is realized (Fig. 8).

在以上撞击过程中,分为三个阶段:In the above impact process, it is divided into three stages:

第一阶段,滑动杆10左移,连接导电板U和K的电阻板13数量保持为4片,连接导电板M和P的电阻板13从初始位置时的1片增加为4片。因此在第一阶段中,固定电磁铁5的电阻不变,电流不变,磁力不变;移动电磁铁14的电阻减小,电流增加,磁力增大;从而使得,固定电磁铁5与移动电磁铁14之间的斥力增大(图7到图8)。In the first stage, the sliding rod 10 is moved to the left, the number of the resistance plates 13 connecting the conductive plates U and K is kept at 4, and the resistance plates 13 connecting the conductive plates M and P are increased from 1 to 4 at the initial position. Therefore, in the first stage, the resistance of the fixed electromagnet 5 does not change, the current does not change, and the magnetic force does not change; the resistance of the moving electromagnet 14 decreases, the current increases, and the magnetic force increases; thus, the fixed electromagnet 5 and the moving electromagnet The repulsive force between the irons 14 increases (FIGS. 7 to 8).

第二阶段,滑动杆10继续左移,连接导电板U和K的电阻板13从4片开始减少至1片,连接导电板M和P的电阻板保持为4片;在第二阶段中,移动电磁铁14的电阻不变,电流不变,磁力不变;固定电磁铁5的电阻增大,电流减小,磁力减小;因此,在第二阶段,固定电磁铁5与移动电磁铁14之间的斥力减小(图8到图9)。In the second stage, the sliding rod 10 continues to move to the left, the resistance plates 13 connecting the conductive plates U and K are reduced from 4 pieces to 1 piece, and the resistance plates connecting the conductive plates M and P remain 4 pieces; in the second stage, The resistance of the moving electromagnet 14 does not change, the current does not change, and the magnetic force does not change; the resistance of the fixed electromagnet 5 increases, the current decreases, and the magnetic force decreases; therefore, in the second stage, the fixed electromagnet 5 and the moving electromagnet 14 The repulsive force between them is reduced (Fig. 8 to Fig. 9).

第三个阶段,滑动杆10继续左移至左极限位,电阻板13完全脱离导电板U和导电板K,此时固定电磁铁5的线圈失去电流,失去磁力;连接电磁板M和电磁板P的电阻板13保持为4片,移动电磁铁14的电阻不变,电流不变,磁力不变。此时,移动电磁铁14和固定电磁铁5之间无磁力作用。因此移动模块2可以停止在左极限位置(图10)。In the third stage, the sliding rod 10 continues to move to the left limit position, the resistance plate 13 is completely separated from the conductive plate U and the conductive plate K, at this time, the coil of the fixed electromagnet 5 loses current and loses its magnetic force; connect the electromagnetic plate M and the electromagnetic plate The resistance plate 13 of P is kept as 4 pieces, the resistance of the moving electromagnet 14 is unchanged, the current is unchanged, and the magnetic force is unchanged. At this time, no magnetic force acts between the moving electromagnet 14 and the fixed electromagnet 5 . Thus the moving module 2 can be stopped at the left limit position (Fig. 10).

以上过程是卸载和变阻力减震结构受到外部金属板18撞击后的减震过程,在这个过程中,减震力先增大,后减小,最后减小至零,从而实现了外部物体阻力先增大后减小至零的变阻力减震,并且不会出现反弹;并且,用于传动的钢丝绳因为松动而切断了驱动力,避免了二次加载。The above process is the shock absorption process after the unloading and variable resistance shock absorbing structure is impacted by the external metal plate 18. During this process, the shock absorbing force first increases, then decreases, and finally decreases to zero, thereby realizing the external object resistance. The variable-resistance damping that first increases and then decreases to zero, and there is no rebound; in addition, the wire rope used for transmission cuts off the driving force due to loosening, avoiding secondary loading.

当外部故障排除后,外部移动物体23复位,此时外部金属板18随之复位。复位启动瞬间,移动电磁铁14由于是通电状态,因而具有磁力作用(图10),这使得移动电磁铁14与外部金属板18之间存在电磁引力,所以在磁力作用下,移动电磁铁18随之右移,进而带动整个移动模块3右移(图11)。继续右移过程中,固定电磁铁2恢复电流导通状态,恢复磁力;移动电磁铁14与固定电磁铁5之间恢复斥力,这种斥力加剧移动电磁铁14的右移复位,最终使得移动模块3右移至极限位。此时,动滑轮11再次对钢丝绳17实现张紧效果,恢复驱动能力(图11)。When the external fault is removed, the external moving object 23 is reset, and at this time, the external metal plate 18 is reset accordingly. At the moment of reset startup, the moving electromagnet 14 has a magnetic force because it is in an electrified state (Fig. 10), which makes the electromagnetic attraction between the moving electromagnet 14 and the external metal plate 18, so under the action of the magnetic force, the moving electromagnet 18 follows move to the right, thereby driving the entire moving module 3 to move to the right (Fig. 11). In the process of continuing to move to the right, the fixed electromagnet 2 restores the current conduction state and restores the magnetic force; the repulsive force between the moving electromagnet 14 and the fixed electromagnet 5 restores, and this repulsion aggravates the right-moving reset of the moving electromagnet 14, and finally makes the mobile module 3Move right to the limit position. At this time, the movable pulley 11 achieves the tensioning effect on the wire rope 17 again, and the driving ability is restored ( FIG. 11 ).

特别的,以上所有过程实现了特殊的有益效果:外部物体出现故障时,卸载和变阻力减震结构1实现了“斥力先增大、后减小至零”的变阻力减震过程;减速至零时,系统不会出现反弹动作;在撞击缓冲过程中,通过动滑轮的作用,实现了钢丝绳驱动力的卸载;当故障排出后,系统可以自动复位,复位至钢丝绳张紧效果;滑轮挡板12可以避免钢丝绳在松动时脱离滑轮的有效范围,这有助于后续复位时,钢丝绳自动复位至滑轮的凹槽内。In particular, all the above processes have achieved special beneficial effects: when the external object fails, the unloading and variable resistance shock absorption structure 1 realizes the variable resistance shock absorption process of "repulsion first increases and then decreases to zero"; deceleration to At zero time, the system will not rebound; during the impact buffering process, the driving force of the wire rope is unloaded through the action of the moving pulley; when the fault is eliminated, the system can automatically reset to the wire rope tensioning effect; pulley baffle 12 It can prevent the wire rope from falling out of the effective range of the pulley when it is loose, which helps the wire rope to automatically return to the groove of the pulley during subsequent reset.

如图14所示,还包括位置检测机构29,在靠近卸载和变阻力减震结构的外部移动物体23能够移动到的框架结构一侧均布置有位置检测机构29。As shown in FIG. 14 , a position detection mechanism 29 is also included, and the position detection mechanism 29 is arranged on the side of the frame structure close to the unloading and variable resistance shock absorbing structure to which the external moving object 23 can move.

如图12和图13所示,位置检测机构29包括固定底板24、平行光发射器25、平面反射器26、弧面反射器27和光线感应尺28,框架结构中一侧布置有固定底板24,固定底板24位于外部移动物体23移动范围的侧方,固定底板24上布置平行光发射器25、弧面反射器27和光线感应尺28,外部移动物体23在朝向固定底板24的侧面固定有平面反射器26;平行光发射器25安装在固定底板24上,并在水平面内与固定底板24的长度方向呈一定的夹角。优选的,该夹角为45度。As shown in FIG. 12 and FIG. 13 , the position detection mechanism 29 includes a fixed base plate 24, a parallel light emitter 25, a flat reflector 26, a curved reflector 27 and a light sensing ruler 28, and a fixed base plate 24 is arranged on one side of the frame structure. , the fixed base plate 24 is located on the side of the movement range of the external moving object 23 , the parallel light emitter 25 , the arc reflector 27 and the light sensing ruler 28 are arranged on the fixed base plate 24 , and the external moving object 23 is fixed on the side facing the fixed base plate 24 . The plane reflector 26; the parallel light emitter 25 is mounted on the fixed base plate 24 and forms a certain angle with the length direction of the fixed base plate 24 in the horizontal plane. Preferably, the included angle is 45 degrees.

如图16所示,外部移动物体23在移动到靠近位置检测机构29时,外部移动物体23撞击到卸载和变阻力减震结构的圆环套15,同时平行光发射器25发出的光线依次经平面反射器26反射、弧面反射器27反射后入射到光线感应尺28被感应检测。这样光线发射器发出的平行光,照射到平面反射器后,光线在平面反射器上的分布长度等于平面镜长度。As shown in FIG. 16 , when the external moving object 23 moves close to the position detection mechanism 29 , the external moving object 23 hits the ring sleeve 15 of the unloading and variable resistance shock-absorbing structure, and the light emitted by the parallel light emitter 25 passes through successively. The plane reflector 26 reflects and the arc reflector 27 reflects and then enters the light sensing ruler 28 to be sensed and detected. In this way, after the parallel light emitted by the light emitter is irradiated on the flat reflector, the distribution length of the light on the flat reflector is equal to the length of the flat mirror.

由此,位置检测机构检测能够检测外部物体撞击移动电磁铁的瞬间位置,该信号发送给控制系统,切断外部主动力,实现双重卸载。In this way, the position detection mechanism can detect the instantaneous position when the external object hits the moving electromagnet, and the signal is sent to the control system to cut off the external active power and realize double unloading.

位置检测机构29的安装方式如下:The installation method of the position detection mechanism 29 is as follows:

固定板24是一个安装板,固定在设备支架上。平行光发射器25安装在固定板24上,并且在水平面内与固定板24的长度方向呈一定的夹角(图12);曲面反射器27和光线感应尺28锁固在固定板24上。平面反射器26安装在外部移动物体23上,并且与平行光发射器25处于同一平面内。The fixing plate 24 is a mounting plate, which is fixed on the equipment bracket. The parallel light emitter 25 is installed on the fixed plate 24 and forms a certain angle with the length direction of the fixed plate 24 in the horizontal plane ( FIG. 12 ); the curved reflector 27 and the light sensing ruler 28 are locked on the fixed plate 24 . The flat reflector 26 is mounted on the external moving object 23 and is in the same plane as the parallel light emitter 25 .

特别的,将位置检测机构29的触发位置安装与上文所述的外部物体23的外部金属板18撞击移动电磁铁14时的起始位置一致(图8)。这种设计的目的是:卸载和变阻力减震结构起作用的瞬间,位置检测机构触发信号。该信号可以传递给控制系统,便于切断总动力,实现电动机卸载功能。In particular, the trigger position of the position detection mechanism 29 is installed to be consistent with the above-mentioned initial position when the outer metal plate 18 of the external object 23 hits the moving electromagnet 14 ( FIG. 8 ). The purpose of this design is: at the moment when the unloading and variable resistance shock absorbing structure works, the position detection mechanism triggers the signal. The signal can be transmitted to the control system, which is convenient to cut off the total power and realize the unloading function of the motor.

位置检测机构的工作原理过程是:The working principle of the position detection mechanism is as follows:

如图13所示,平行光发射器25、弧面反射器27、光线感应尺28均安装在固定底板24上。平面发射器26则安装在外部移动物体23的侧面(图16),并且随着外部移动物体23移动。As shown in FIG. 13 , the parallel light emitter 25 , the arc reflector 27 , and the light sensing ruler 28 are all mounted on the fixed base plate 24 . The plane transmitter 26 is mounted on the side of the external moving object 23 ( FIG. 16 ), and moves with the external moving object 23 .

当平面反射器26移动到预先设定的信号触发位置时,平行光发射器25发射的平行光束照射到平面反射器26上,进行第一次反射;反射后的光线照射至曲面反射器27上,进行第二次反射;反射后的光线照射到光线感应尺28上。光线感应尺28可以识别光线在感应尺上的分布长度L1(图13),此时为触发信号。当When the flat reflector 26 moves to the preset signal trigger position, the parallel light beam emitted by the parallel light emitter 25 irradiates the flat reflector 26 for the first reflection; the reflected light irradiates the curved reflector 27 , the second reflection is performed; the reflected light is irradiated on the light sensing ruler 28 . The light sensing ruler 28 can identify the distribution length L1 ( FIG. 13 ) of light on the sensing ruler, which is a trigger signal at this time. when

当平面反射器26在其他位置时,平行光发射器25发出的光线,未照射到平面反射器26上;或者部分光线照射到平面反射器26上进行反射,另一部分光线从平面反射器26的侧面射过,未进行反射。光线部分反射的情况下,经过两次反射的光线照射到光线感应尺28上后,光线在感应尺上的分布长度为L2。对比L1和L2的数据,即可换算出外部物体的偏移方向和偏移量(图13)。When the flat reflector 26 is in other positions, the light emitted by the parallel light emitter 25 does not strike the flat reflector 26; Side shot, not reflected. In the case that the light is partially reflected, after the light reflected twice is irradiated on the light sensing ruler 28, the distribution length of the light on the sensing ruler is L2. By comparing the data of L1 and L2, the offset direction and offset of the external object can be converted (Figure 13).

特别的,预先选定平面反射器26的长度,具体要求为:在最佳触发位置时,光线发射器25发出的平行光,在平面反射器上的分布长度恰好等于平面反射器的长度。In particular, the length of the plane reflector 26 is preselected, and the specific requirements are: at the optimal trigger position, the parallel light emitted by the light emitter 25 has a distribution length on the plane reflector exactly equal to the length of the plane reflector.

特别的,光线在第二次反射时采用的是曲面反射器,能够放大光线反射后的扩散角,提高检测精度。In particular, a curved reflector is used for the second reflection of the light, which can amplify the diffusion angle of the reflected light and improve the detection accuracy.

由此通过位置检测机构29能够:检测到外部物体在信号触发位置时,将信号传递给控制系统,控制系统将外部动力装置停止;外部物体不在信号触发位置时,检测外部物体的偏移量。Therefore, the position detection mechanism 29 can: when the external object is detected at the signal trigger position, the signal is transmitted to the control system, and the control system stops the external power device; when the external object is not at the signal trigger position, the offset of the external object can be detected.

如图7至图16为本发明的较佳实例。7 to 16 are preferred examples of the present invention.

本发明的具体实施工作过程为:The specific implementation working process of the present invention is:

如图14所示,横支架19和竖支架20构成系统框架结构,框架结构上安装定滑轮,钢丝绳绕定滑轮连接外部移动物体23。电机21为外部动力装置,安装在框架上,电机轴通过滑轮给钢丝绳驱动。卸载和变阻力减震结构安装在竖支架20上,并通过张紧角度连入钢丝绳驱动系统中。位置检测机构29安装在外部移动物体的侧方位置,锁固在横支架上。特别的,位置检测机构29的的平面反射器26锁固在外部移动物体的侧面。As shown in FIG. 14 , the horizontal support 19 and the vertical support 20 constitute a system frame structure, a fixed pulley is installed on the frame structure, and the wire rope is connected to the external moving object 23 around the fixed pulley. The motor 21 is an external power device, installed on the frame, and the motor shaft drives the wire rope through a pulley. The unloading and variable resistance damping structure is installed on the vertical support 20 and connected to the wire rope drive system through the tension angle. The position detection mechanism 29 is installed at the lateral position of the external moving object, and is locked on the horizontal bracket. In particular, the flat reflector 26 of the position detection mechanism 29 is locked to the side of the external moving object.

(1)初始状态,钢丝绳17张紧。(1) In the initial state, the wire rope 17 is tensioned.

此时,移动模块处于拉紧钢丝绳17的极限位置时,电阻组件中至少一个电阻板13两侧分别电连接到固定导电线圈9所连接的一组导电板组的两个导电板6上使得两个导电板6相导通。即此时只有仅最靠近钢丝绳17的一片电阻板连通移动导电线圈16所连接的导电板6。At this time, when the moving module is in the limit position of tightening the wire rope 17, both sides of at least one resistance plate 13 in the resistance assembly are electrically connected to the two conductive plates 6 of a group of conductive plates connected to the fixed conductive coil 9 respectively, so that the two Each conductive plate 6 is in conduction. That is to say, only the resistance plate closest to the wire rope 17 is connected to the conductive plate 6 connected to the moving conductive coil 16 at this time.

(2)然后电机21驱动钢丝绳运动,从而驱动外部物体23运动。(2) Then the motor 21 drives the wire rope to move, thereby driving the external object 23 to move.

当系统发生故障并且其他防护功能失效时,外部物体23会在动力或惯性力作用下撞向卸载和变阻力减震结构1。When the system fails and other protective functions fail, the external object 23 will hit the unloading and variable resistance shock absorbing structure 1 under the action of dynamic or inertial force.

(3)碰撞瞬间,外部物体23的外部金属板18率先接触卸载和变阻力减震结构1的移动电磁铁的侧端面(图7),卸载和变阻力减震结构开始起作用。移动电磁铁14受到撞击后开始向左移动,安装在移动模块3左端的动滑轮11随之左移,动滑轮11左移后,钢丝绳失去张紧作用,驱动力被卸载,外部物体23不再承受驱动力(图8)。(3) At the moment of collision, the outer metal plate 18 of the external object 23 first contacts the side end face of the moving electromagnet of the unloading and variable resistance shock absorbing structure 1 (FIG. 7), and the unloading and variable resistance shock absorbing structure begins to function. After the moving electromagnet 14 is impacted, it starts to move to the left, and the movable pulley 11 installed on the left end of the moving module 3 moves to the left. After the movable pulley 11 moves to the left, the wire rope loses its tensioning effect, the driving force is unloaded, and the external object 23 is no longer driven. force (Figure 8).

与此同时,在这个瞬时位置,位置检测机构29中的平面反射器运动到预设的最佳信号位置(图16、图13),此时发出信号给控制系统。控制系统切断电机21的动力(图15),实现双重卸载。At the same time, at this instantaneous position, the planar reflector in the position detection mechanism 29 moves to the preset optimal signal position (FIG. 16, FIG. 13), and sends a signal to the control system at this time. The control system cuts off the power of the motor 21 (Fig. 15) to achieve double unloading.

此时在图8的状态下,固定导电线圈9和移动导电线圈16各自的通电电流均最大,固定导电线圈9和移动导电线圈16之间产生的排斥力最大,使得外部物体23移动此时状态位置下的阻力最大。At this time, in the state of FIG. 8 , the energization currents of the fixed conductive coil 9 and the movable conductive coil 16 are the largest, and the repulsive force generated between the fixed conductive coil 9 and the movable conductive coil 16 is the largest, so that the external object 23 moves in this state. The resistance is greatest in the position.

(4)在移动模块3左移过程中,连通导电板M与P的电阻板13的数量逐渐增加;连通导电板U与K的电阻板13的数量逐渐减小。(4) During the process of moving the moving module 3 to the left, the number of the resistance plates 13 connecting the conductive plates M and P gradually increases; the number of the resistance plates 13 connecting the conductive plates U and K gradually decreases.

首先变成如图9所示的状态,固定导电线圈9的通电电流减小,和移动导电线圈16的通电电流不变,固定导电线圈9和移动导电线圈16之间产生的排斥力逐渐减小。First, it becomes the state shown in FIG. 9 , the energization current of the fixed conductive coil 9 decreases, and the energization current of the movable conductive coil 16 remains unchanged, and the repulsive force generated between the fixed conductive coil 9 and the movable conductive coil 16 gradually decreases .

然后变成如图10所示的状态,固定导电线圈9的通电电流减小为零,和移动导电线圈16的通电电流不变,由于固定导电线圈9没有通电电流,固定导电线圈9和移动导电线圈16之间不再产生的排斥力,无法驱动移动模块移动,移动模块不会反弹。Then it becomes the state shown in FIG. 10 , the energized current of the fixed conductive coil 9 is reduced to zero, and the energized current of the moving conductive coil 16 remains unchanged. Since the fixed conductive coil 9 has no energized current, the fixed conductive coil 9 and the moving conductive coil The repulsive force no longer generated between the coils 16 cannot drive the moving module to move, and the moving module will not rebound.

由此实现的效果是,固定电磁铁5与移动电磁铁14之间产生的排斥力先增大,后减小,最后减小至零。因此实现了变阻力的减震过程,并且不会反弹。The effect achieved by this is that the repulsive force generated between the fixed electromagnet 5 and the moving electromagnet 14 first increases, then decreases, and finally decreases to zero. Therefore, the shock absorption process of variable resistance is realized, and there is no rebound.

(5)当外部故障排除后,外部移动物体23复位,此时外部金属板18随之复位。复位启动瞬间,移动电磁铁14由于是通电状态,因而具有磁力作用(图10),这使得移动电磁铁14与外部金属板18之间存在电磁引力,所以在磁力作用下,移动电磁铁18随之右移,进而带动整个移动模块3右移(图11)。(5) After the external fault is eliminated, the external moving object 23 is reset, and at this time, the external metal plate 18 is reset accordingly. At the moment of reset startup, the moving electromagnet 14 has a magnetic force because it is in an electrified state (Fig. 10), which makes the electromagnetic attraction between the moving electromagnet 14 and the external metal plate 18, so under the action of the magnetic force, the moving electromagnet 18 follows move to the right, thereby driving the entire moving module 3 to move to the right (Fig. 11).

继续右移过程中,固定电磁铁2恢复电流导通状态,恢复磁力;移动电磁铁14与固定电磁铁5之间恢复斥力,这种斥力加剧移动电磁铁14的右移复位,最终使得移动模块3右移至极限位。此时,动滑轮11再次对钢丝绳17实现张紧效果,恢复驱动能力(图11)。In the process of continuing to move to the right, the fixed electromagnet 2 restores the current conduction state and restores the magnetic force; the repulsive force between the moving electromagnet 14 and the fixed electromagnet 5 restores, and this repulsion aggravates the right-moving reset of the moving electromagnet 14, and finally makes the mobile module 3Move right to the limit position. At this time, the movable pulley 11 achieves the tensioning effect on the wire rope 17 again, and the driving ability is restored ( FIG. 11 ).
