技术领域Technical Field
本发明属于起重机设备技术领域，具体涉及一种起重机用联轴器。The invention belongs to the technical field of crane equipment, and in particular relates to a coupling for a crane.
背景技术Background Art
起重机是指在一定范围内垂直提升和水平搬运重物的多动作起重机械；变幅机构是臂架型起重机的主要工作机构，用于改变起重机的幅度，即改变吊钩（或抓斗）中心至起重机回转中心轴线的水平距离，以适应起重机在不同条件下装卸物品；变幅机构包括电机、联轴器、卷筒等，通过电机带动联轴器转动，进而带动卷筒转动，进而改变起重机的幅度。A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range; the luffing mechanism is the main working mechanism of a jib crane, used to change the amplitude of the crane, that is, to change the horizontal distance from the center of the hook (or grab) to the center axis of the crane's rotation, so as to adapt the crane to loading and unloading objects under different conditions; the luffing mechanism includes a motor, a coupling, a drum, etc., and the motor drives the coupling to rotate, which in turn drives the drum to rotate, thereby changing the amplitude of the crane.
另外根据起重机承载能力的不同，变幅机构需使用不同的卷筒以及电机；对于不同的电机以及卷筒，电机以及卷筒的连接轴的尺寸不一，使得不同的联轴器方能连接不同的电机与卷筒，实现卷筒的正常工作；但是联轴器多为固定式的设计，造成联轴器只能连接固定尺寸的连接轴，不能适应不同尺寸的连接轴；造成现有的联轴器适应性较差，无法有效的适应多种规格的连接轴的直径；使得当联轴器发生故障时，维护人员无法及时有效的对联轴器进行更换，需购买同等型号的联轴器进行安装，极大的影响了起重机修复的时间。In addition, according to the different load-bearing capacities of the crane, the luffing mechanism needs to use different drums and motors; for different motors and drums, the sizes of the connecting shafts of the motors and drums are different, so different couplings can be used to connect different motors and drums to achieve the normal operation of the drum; but the couplings are mostly fixed in design, which means that the couplings can only connect connecting shafts of fixed sizes and cannot adapt to connecting shafts of different sizes; the existing couplings have poor adaptability and cannot effectively adapt to the diameters of connecting shafts of various specifications; when the coupling fails, the maintenance personnel cannot replace the coupling in a timely and effective manner, and need to purchase a coupling of the same model for installation, which greatly affects the repair time of the crane.

具体实施方式DETAILED DESCRIPTION
一种起重机用联轴器3，如图1-7所示，包括机架，机架上转动连接有卷筒5，卷筒5两端均固接有挡环6；所述卷筒5同轴连接有联轴器3，联轴器3上连接有电机2，电机2和卷筒5上均连接有与联轴器3对应的连接轴12；所述联轴器3包括联轴器本体8，联轴器本体8两端均连接有固定仓9；一对所述固定仓9上均连接轴12连接花键轴13，连接轴12上设有与连接花键轴13对应的连接花键槽33，固定仓9上还设有对连接轴12外壁固定的外固定结构10；A coupling 3 for a crane, as shown in Fig. 1-7, comprises a frame, a drum 5 is rotatably connected to the frame, and retaining rings 6 are fixedly connected to both ends of the drum 5; the drum 5 is coaxially connected to the coupling 3, the coupling 3 is connected to the motor 2, and the motor 2 and the drum 5 are both connected to a connecting shaft 12 corresponding to the coupling 3; the coupling 3 comprises a coupling body 8, and both ends of the coupling body 8 are connected to a fixed bin 9; a pair of the fixed bins 9 are connected to a spline shaft 13 connected to the connecting shaft 12, and the connecting shaft 12 is provided with a connecting spline groove 33 corresponding to the connecting spline shaft 13, and the fixed bin 9 is also provided with an external fixing structure 10 that fixes the outer wall of the connecting shaft 12;
本发明在使用时，通过电机2、联轴器3、卷筒5等的设置，使电机2通过联轴器3带动卷筒5转动，进而改变起重机的幅度；另外联轴器本体8与连接轴12连接时，通过连接花键轴13与连接轴12的连接花键槽33进行内连接，通过固定仓9上的外固定结构10对连接轴12的外壁进行连接，进一步的提高联轴器本体8与连接轴12连接的稳定性。When the present invention is in use, through the arrangement of the motor 2, the coupling 3, the drum 5, etc., the motor 2 drives the drum 5 to rotate through the coupling 3, thereby changing the amplitude of the crane; in addition, when the coupling body 8 is connected to the connecting shaft 12, the connecting spline shaft 13 is internally connected to the connecting spline groove 33 of the connecting shaft 12, and the outer wall of the connecting shaft 12 is connected through the external fixing structure 10 on the fixed bin 9, thereby further improving the stability of the connection between the coupling body 8 and the connecting shaft 12.
所述外固定结构10包括多个沿圆周设置的且沿固定仓9径向滑动的中固定块22，固定仓9内设有带动多个中固定块22同步运动的调节结构，多个所述中固定块22两侧均沿圆周方向均滑动连接有侧固定块23；所述中固定块22上转动连接有一对连接杆21，一对所述连接杆21分别与一对所述侧固定块23转动连接；所述连接轴12上固接有连接块29，连接块29上固接有中固定齿32，中固定齿32两侧设有与连接块29固接的侧固定齿24，中固定块22和侧固定块23上分别设有与中固定齿32、侧固定齿24对应的固定槽。外固定结构10在使用时，通过调节结构对中固定块22进行调节，使中固定块22沿固定仓9径向滑动；在连接杆21的作用下，使侧固定块23通过扇形块30沿中固定块22沿圆周方向滑动，改变侧固定块23与中固定块22之间的距离。The external fixed structure 10 includes a plurality of middle fixed blocks 22 which are arranged along the circumference and slide radially along the fixed bin 9. An adjusting structure is provided in the fixed bin 9 to drive the plurality of middle fixed blocks 22 to move synchronously. Both sides of the plurality of middle fixed blocks 22 are slidably connected with side fixed blocks 23 along the circumferential direction; a pair of connecting rods 21 are rotatably connected to the middle fixed block 22, and the pair of connecting rods 21 are rotatably connected to the pair of side fixed blocks 23 respectively; a connecting block 29 is fixedly connected to the connecting shaft 12, a middle fixed tooth 32 is fixedly connected to the connecting block 29, and side fixed teeth 24 fixed to the connecting block 29 are provided on both sides of the middle fixed tooth 32, and fixing grooves corresponding to the middle fixed teeth 32 and the side fixed teeth 24 are respectively provided on the middle fixed block 22 and the side fixed block 23. When the external fixing structure 10 is in use, the central fixing block 22 is adjusted through the adjustment structure so that the central fixing block 22 slides radially along the fixing bin 9; under the action of the connecting rod 21, the side fixing blocks 23 slide along the circumferential direction of the central fixing block 22 through the fan-shaped blocks 30, thereby changing the distance between the side fixing blocks 23 and the central fixing block 22.
具体的，根据连接轴12直径的大小，对中固定块22进行调节；如图3和图4所示，在连接杆21的作用下，使侧固定块23沿中固定块22滑动，使中固定块22与侧固定块23组合，所能对连接轴12固定的弧面的长度与连接轴12外周等分的弧面对应，即多组中固定块22与侧固定块23的组合，分别与连接轴12外周等分的弧面对应，以提高中固定块22与侧固定块23对连接轴12固定的稳定性，使本申请能够有效的适应多种规格的连接轴12的直径，提高本申请的适应性；中固定块22与侧固定块23通过固定槽与连接块29上的中固定齿32、侧固定齿24相配合，实现对连接轴12进行固定。Specifically, the center fixing block 22 is adjusted according to the diameter of the connecting shaft 12; as shown in Figures 3 and 4, under the action of the connecting rod 21, the side fixing block 23 slides along the center fixing block 22, so that the center fixing block 22 is combined with the side fixing block 23, and the length of the arc surface that can fix the connecting shaft 12 corresponds to the arc surface that is equally divided into the outer periphery of the connecting shaft 12, that is, the combination of multiple groups of center fixing blocks 22 and side fixing blocks 23, respectively corresponds to the arc surface that is equally divided into the outer periphery of the connecting shaft 12, so as to improve the stability of the center fixing block 22 and the side fixing block 23 in fixing the connecting shaft 12, so that the present application can effectively adapt to the diameters of connecting shafts 12 of various specifications, thereby improving the adaptability of the present application; the center fixing block 22 and the side fixing block 23 cooperate with the center fixing teeth 32 and the side fixing teeth 24 on the connecting block 29 through the fixing groove to fix the connecting shaft 12.
即若连接轴12直径大时，等分后的弧面相对较大，对中固定块22进行调节，使侧固定块23与中固定块22之间组合所能固定的弧面增大；若连接轴12直径小时，等分后的弧面相对较小，使侧固定块23与中固定块22之间组合所能固定的弧面减小，不过侧固定块23与中固定块22之间组合，与连接轴12等分弧面所占的角度对应，使多组中固定块22与侧固定块23的组合能够对连接轴12外壁进行全面的固定，以提高连接轴12与外固定结构10连接的稳定性。That is, if the diameter of the connecting shaft 12 is large, the arc surface after being equally divided is relatively large, and the central fixing block 22 is adjusted to increase the arc surface that can be fixed by the combination of the side fixing block 23 and the central fixing block 22; if the diameter of the connecting shaft 12 is small, the arc surface after being equally divided is relatively small, so that the arc surface that can be fixed by the combination of the side fixing block 23 and the central fixing block 22 is reduced, but the combination of the side fixing block 23 and the central fixing block 22 corresponds to the angle occupied by the equally divided arc surface of the connecting shaft 12, so that the combination of multiple groups of central fixing blocks 22 and side fixing blocks 23 can comprehensively fix the outer wall of the connecting shaft 12, so as to improve the stability of the connection between the connecting shaft 12 and the external fixing structure 10.
进一步地，所述连接块29的内壁的直径与连接轴12的外壁的直径相等，提高连接块29与连接轴12连接的稳定性；连接块29的外壁的直径与侧固定块23、中固定块22的内壁的直径相等，使中固定块22、侧固定块23与连接块29连接更加的紧密，提高本申请的稳定性。Furthermore, the diameter of the inner wall of the connecting block 29 is equal to the diameter of the outer wall of the connecting shaft 12, thereby improving the stability of the connection between the connecting block 29 and the connecting shaft 12; the diameter of the outer wall of the connecting block 29 is equal to the diameter of the inner wall of the side fixing block 23 and the middle fixing block 22, thereby making the middle fixing block 22, the side fixing block 23 and the connecting block 29 more tightly connected, thereby improving the stability of the present application.
进一步地，如图5所示，所述调节结构包括与固定仓9滑动连接的调节板14，调节板14上转动连接有多个推杆25，多个所述推杆25分别与多个所述中固定块22转动连接；所述固定仓9上转动连接有调节螺杆18，调节螺杆18上固接有调节旋钮15；所述固定仓9内固接有导向杆27，调节板14与导向杆27滑动连接。Further, as shown in Figure 5, the adjustment structure includes an adjustment plate 14 slidably connected to the fixed bin 9, and a plurality of push rods 25 are rotatably connected to the adjustment plate 14, and the plurality of push rods 25 are rotatably connected to the plurality of middle fixed blocks 22 respectively; an adjustment screw 18 is rotatably connected to the fixed bin 9, and an adjustment knob 15 is fixed to the adjustment screw 18; a guide rod 27 is fixed in the fixed bin 9, and the adjustment plate 14 is slidably connected to the guide rod 27.
调节结构在使用时，通过调节旋钮15带动调节螺杆18转动，调节螺杆18带动调节板14沿导向杆27滑动，调节板14通过推杆25带动中固定块22沿固定仓9径向滑动；通过调节板14、推杆25同步带动多个中固定块22沿固定仓9径向滑动，提高本申请的便利性。When the adjustment structure is in use, the adjustment screw 18 is driven to rotate through the adjustment knob 15, and the adjustment screw 18 drives the adjustment plate 14 to slide along the guide rod 27.
