背景技术Background Art
伴随着我国城市轨道交通运营规模的不断扩大，城市轨道交通将进入大运维时代，轨道交通屏蔽门系统是保证乘客候车与列车运行安全的重要保障，也逐步达到100万次使用寿命，急需对其核心零部件进行更换或技改，由于屏蔽门系统建设期的生产制造与运营大修期的技术改造由不同的厂家进行实施，不同站台门厂家的核心零部件技术方案、接口参数均不同，造成屏蔽门技改方案成本高、技术难度大、施工周期长等问题。With the continuous expansion of the operation scale of urban rail transit in my country, urban rail transit will enter the era of large-scale operation and maintenance. The rail transit platform door system is an important guarantee to ensure the safety of passengers waiting and train operation. It is also gradually reaching a service life of 1 million times, and its core components are urgently needed to be replaced or technically upgraded. Since the production and manufacturing during the construction period and the technical transformation during the operation overhaul period of the platform door system are implemented by different manufacturers, the technical solutions and interface parameters of the core components of different platform door manufacturers are different, resulting in problems such as high cost, high technical difficulty and long construction period of the platform door technical transformation plan.
门锁装置是屏蔽门系统的核心部件之一，也是屏蔽门技改项目的重要组成部分，手动解锁装置是屏蔽门系统控制模式的最高级，是保障屏蔽门系统安全性的最后一道屏障，其与门锁装置配合实现手动解锁功能，由于不同厂家的门锁装置尺寸不同，手动解锁装置的解锁行程也不同，当技改门锁装置的解锁行程大于手动解锁的行程时，手动解锁装置无法实现手动解锁功能，也需要对手动解锁装置进行技术改进，传统解决方案是将滑动门顶杆的结构重新设计并增大行程，但是造成技改方案实施难度大、制造成本高、实施周期长等，严重影响地铁运营，因此急需对手动解锁装置进行研究。The door lock device is one of the core components of the shielding door system and an important part of the shielding door technical transformation project. The manual unlocking device is the highest level of the shielding door system control mode and the last barrier to ensure the safety of the shielding door system. It cooperates with the door lock device to realize the manual unlocking function. Due to the different sizes of door lock devices from different manufacturers, the unlocking stroke of the manual unlocking device is also different. When the unlocking stroke of the technically modified door lock device is greater than the manual unlocking stroke, the manual unlocking device cannot realize the manual unlocking function, and technical improvements to the manual unlocking device are also needed. The traditional solution is to redesign the structure of the sliding door top rod and increase the stroke, but this makes the technical transformation plan difficult to implement, the manufacturing cost is high, the implementation cycle is long, etc., which seriously affects the subway operation. Therefore, it is urgent to study the manual unlocking device.

During the project, it was found that 1. the unlocking stroke of the newly replaced door lock device was greater than the stroke of the manual unlocking device; 2. the position of the sliding door top rod did not match the unlocking position of the newly replaced door lock device. Therefore, a project was initiated to study the above-mentioned problems and an improvement plan was proposed.

具体实施方式DETAILED DESCRIPTION
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
在本发明中，除非另有明确的规定和限定，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。In the present invention, unless otherwise clearly stipulated and limited, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
如附图1-3所示，行程放大机构，包括门锁装置，所述门锁装置内设置解锁转柄；还包括滑动门，滑动门设置解锁顶杆，所述门锁装置与滑动门之间设置行程放大机构，行程放大机构的放大系数大于或等于门锁装置的解锁行程与滑动门解锁顶杆的最大移动行程之比。As shown in Figures 1-3, the stroke amplification mechanism includes a door lock device, in which an unlocking handle is arranged; and also includes a sliding door, in which an unlocking push rod is arranged. The stroke amplification mechanism is arranged between the door lock device and the sliding door, and the amplification coefficient of the stroke amplification mechanism is greater than or equal to the ratio of the unlocking stroke of the door lock device to the maximum moving stroke of the unlocking push rod of the sliding door.
进一步的，行程放大机构包括输入端与输出端，所述输入端抵靠解锁顶杆，所述输出端抵靠解锁转柄。Furthermore, the stroke amplification mechanism includes an input end and an output end, wherein the input end abuts against the unlocking push rod, and the output end abuts against the unlocking turning handle.
城市轨道交通站台上推拉结构的滑动门以及滑动门上的解锁顶杆属于成熟的现有技术，本发明不涉及对该结构的修改，不再赘述；而屏蔽门上的门锁机构，是屏蔽门达到许用寿命后需要更换的核心部件，而因为客观原因更换的门锁机构不再是原厂生产或是原型号，虽然解锁原理不变，但是尺寸及部分细节产生改变，就导致了滑动门的解锁顶杆与新的门锁机构不配合的情况，当技改门锁装置的解锁行程大于手动解锁的行程时，手动解锁装置无法实现手动解锁功能，本发明通过在门锁装置与滑动门之间设置行程放大机构，解决了当前施工时改门锁装置的解锁行程大于手动解锁的行程时，手动解锁装置无法实现手动解锁功能的问题。The sliding doors of the push-pull structure on the urban rail transit platform and the unlocking push rods on the sliding doors are mature prior arts. The present invention does not involve modifications to the structure and will not be described in detail. The door lock mechanism on the shield door is a core component that needs to be replaced after the shield door reaches its service life. Due to objective reasons, the replaced door lock mechanism is no longer produced by the original factory or is no longer the original model. Although the unlocking principle remains unchanged, the size and some details have changed, which leads to the situation that the unlocking push rod of the sliding door does not cooperate with the new door lock mechanism. When the unlocking stroke of the technically modified door lock device is greater than the manual unlocking stroke, the manual unlocking device cannot achieve the manual unlocking function. The present invention solves the problem that the manual unlocking device cannot achieve the manual unlocking function when the unlocking stroke of the modified door lock device is greater than the manual unlocking stroke during current construction by arranging a stroke amplification mechanism between the door lock device and the sliding door.
进一步的，输入端与输出端偏心设置，详细的，由于门锁机构不再是原厂生产或是原型号，所以门锁机构的解锁位置所在垂线与解锁顶杆轴线可能不再共线，所以需要输入端与输出端偏心设置，详细的，落实到附图1中第一导向件2与第二导向件13不位于同一直线设置，且在附图2中输入端与解锁顶杆位置对应，输出端与解锁转柄位置对应。Furthermore, the input end and the output end are eccentrically arranged. In detail, since the door lock mechanism is no longer produced by the original factory or the original model, the vertical line where the unlocking position of the door lock mechanism is located and the axis of the unlocking push rod may no longer be colinear, so the input end and the output end need to be eccentrically arranged. In detail, as shown in Figure 1, the first guide member 2 and the second guide member 13 are not located in the same straight line, and in Figure 2, the input end corresponds to the position of the unlocking push rod, and the output end corresponds to the position of the unlocking handle.
一种行程缩放机构，包括安装座4，所述安装座4上设置第一曲柄滑块机构以及第二曲柄滑块机构，第一曲柄滑块机构中的第一滑块3作为输出端，第二曲柄滑块机构中的第二滑块14作为输入端；第一曲柄滑块机构中的第一曲柄81与第二曲柄滑块机构中的第二曲柄82之间固定连接，形成V型的曲柄共用件8，曲柄共用件8铰接安装座4，使第一曲柄81与第二曲柄82长度不相等，使得对第二滑块14输入行程q时，带动第一滑块3输入行程p，p≠q。A stroke scaling mechanism comprises a mounting seat 4, on which a first crank slider mechanism and a second crank slider mechanism are arranged, wherein the first slider 3 in the first crank slider mechanism serves as an output end, and the second slider 14 in the second crank slider mechanism serves as an input end; a first crank 81 in the first crank slider mechanism and a second crank 82 in the second crank slider mechanism are fixedly connected to form a V-shaped crank common part 8, and the crank common part 8 is hinged to the mounting seat 4 so that the lengths of the first crank 81 and the second crank 82 are unequal, so that when a stroke q is input to the second slider 14, the first slider 3 is driven to input a stroke p, and p≠q.
进一步的，行程放大机构包括安装座4，安装座4上设置第一曲柄滑块机构，第一曲柄滑块机构包括第一导轨2，第一导向件2固定连接安装座4，第一导向件2滑动连接第一滑块3，第一滑块3上端固定连接输出端，第一滑块3铰接第一连杆6一端，第一连杆6另一端铰接第一曲柄81一端；Further, the stroke amplification mechanism includes a mounting seat 4, a first crank slider mechanism is arranged on the mounting seat 4, the first crank slider mechanism includes a first guide rail 2, a first guide member 2 is fixedly connected to the mounting seat 4, the first guide member 2 is slidably connected to a first slider 3, an upper end of the first slider 3 is fixedly connected to the output end, the first slider 3 is hinged to one end of a first connecting rod 6, and the other end of the first connecting rod 6 is hinged to one end of a first crank 81;
安装座4上还设置第二曲柄滑块机构，第二曲柄滑块机构包括第二导向件13，第二导向件13滑动连接第二滑块14，第二滑块14下端固定连接输入端，第二滑块14铰接第二连杆12一端，第二连杆12另一端铰接第二曲柄82一端；A second crank slider mechanism is also provided on the mounting seat 4, and the second crank slider mechanism includes a second guide member 13, the second guide member 13 is slidably connected to a second slider 14, the lower end of the second slider 14 is fixedly connected to the input end, the second slider 14 is hinged to one end of a second connecting rod 12, and the other end of the second connecting rod 12 is hinged to one end of a second crank 82;
第一曲柄81另一端与第二曲柄82另一端固定连接形成曲柄共用件8，连接处通过设置轴孔铰接曲柄连接轴11一端，曲柄连接轴11另一端固定连接安装座4；The other end of the first crank 81 is fixedly connected to the other end of the second crank 82 to form a crank common member 8, and the connection is hinged to one end of the crank connecting shaft 11 by setting an axial hole, and the other end of the crank connecting shaft 11 is fixedly connected to the mounting seat 4;
详细的，用于本申请中手动解锁装置的行程缩放机构中，第一曲柄81的长度大于第二曲柄82的长度，当然的，第一连杆6与第二连杆12的长度也会影响行程缩放系数，但是实际设计中往往第一连杆6与第二连杆12长度接近，对结果影响较小。In detail, in the stroke scaling mechanism of the manual unlocking device used in the present application, the length of the first crank 81 is greater than the length of the second crank 82. Of course, the lengths of the first connecting rod 6 and the second connecting rod 12 will also affect the stroke scaling coefficient, but in actual design, the lengths of the first connecting rod 6 and the second connecting rod 12 are often close, which has little effect on the result.
第一曲柄滑块机构、第二曲柄滑块机构构成双曲柄滑块机构，当以第二曲柄滑块机构的第二滑块14作为直线运动输入点，以第一曲柄滑块机构的第一滑块3作为直线运动的输出点，通过双曲柄滑块机构的联动，实现小行程直线运动的输入控制大行程直线运动的输出，实现直线运动行程的放大功能。The first crank slider mechanism and the second crank slider mechanism constitute a double crank slider mechanism. When the second slider 14 of the second crank slider mechanism is used as the input point of the linear motion and the first slider 3 of the first crank slider mechanism is used as the output point of the linear motion, through the linkage of the double crank slider mechanism, the input of the small-stroke linear motion controls the output of the large-stroke linear motion, thereby realizing the function of amplifying the linear motion stroke.

The crank common member 8 is limited by the two limit blocks to be limited in the unlocked extreme position and the initial position.
详细的，第一滑块3上端固定连接顶头1作为输出端用于与解锁转柄相抵靠，第二滑块14下端固定连接圆盘15作为输入端用于与解锁顶杆相抵靠。In detail, the upper end of the first slider 3 is fixedly connected to the head 1 as an output end for abutting against the unlocking handle, and the lower end of the second slider 14 is fixedly connected to the disk 15 as an input end for abutting against the unlocking push rod.
该行程放大机构通过安装座4、螺栓组件5固定安装在门锁装置下部的门机梁上，其输出端对应门锁装置的解锁转柄，其输入端对应滑动门的解锁顶杆，如附图2所示。如附3所示，乘客通过转动滑动门的手动把手将解锁顶杆向上顶起（这一操作基于现有技术的滑动门结构），解锁顶杆推动圆盘15、第二滑块14沿第二导向件13竖直向上直线运动，第二滑块14的竖直向上直线运动作为动力输入，通过第二连杆12克服复位扭簧10的作用力带动第二曲柄82反向转动，第二曲柄82与第一曲柄81均属于曲柄共用件8，且第二曲柄82的长度小于第一曲柄81的长度，第二曲柄82带动第一曲柄81同步反向转动，进而通过第一连杆6带动第一滑块3沿第一导向件2竖直向上直线运动，第一滑块3带动其顶部的顶头1推动门锁装置的解锁转柄转动，解锁转柄带动锁钩同步转动，完成手动解锁操作，其中第二滑块14的直线行程小于第一滑块3的直线行程，确保了小行程解锁顶杆对大行程解锁转柄的手动解锁操作；乘客通反向转动滑动门的手动把手将顶杆反向向下复位，曲柄共用件8在复位扭簧10作用下正向转动复位到与第二限位块9相接触，即为初始状态，曲柄共用件8的第二曲柄82正向转动通过第二连杆12带动第二滑块14沿第二导向件13竖直向下运动复位，同时曲柄共用件8的第一曲柄81同步正向转动通过第一连杆6带动第一滑块3沿第一导向件2竖直向下运动复位，顶头1与门锁装置的解锁转柄脱离，完成手动解锁装置的复位。The stroke amplification mechanism is fixedly mounted on the door machine beam at the lower part of the door lock device through the mounting seat 4 and the bolt assembly 5. Its output end corresponds to the unlocking handle of the door lock device, and its input end corresponds to the unlocking push rod of the sliding door, as shown in Figure 2. As shown in Figure 3, the passenger pushes the unlocking push rod upward by turning the manual handle of the sliding door (this operation is based on the sliding door structure of the prior art), and the unlocking push rod pushes the disc 15 and the second slider 14 to move vertically upward along the second guide member 13. The vertical upward linear motion of the second slider 14 is used as power input, and the second crank 82 is driven to rotate in the opposite direction through the second connecting rod 12 to overcome the force of the reset torsion spring 10. The second crank 82 and the first crank 81 both belong to the crank common part 8, and the length of the second crank 82 is less than that of the first crank 81. The second crank 82 drives the first crank 81 to rotate in the opposite direction synchronously, and then drives the first slider 3 to move vertically upward along the first guide member 2 through the first connecting rod 6. The first slider 3 drives the top head 1 at its top to push the unlocking handle of the door lock device to rotate, and the unlocking handle 81 is driven to rotate synchronously. The handle drives the lock hook to rotate synchronously to complete the manual unlocking operation, wherein the linear stroke of the second slider 14 is smaller than the linear stroke of the first slider 3, ensuring the manual unlocking operation of the large-stroke unlocking handle by the small-stroke unlocking push rod; the passenger reverses the manual handle of the sliding door to reset the push rod downward, and the crank common part 8 rotates forward under the action of the reset torsion spring 10 to reset to contact with the second limit block 9, which is the initial state. The second crank 82 of the crank common part 8 rotates forward through the second connecting rod 12 to drive the second slider 14 to move vertically downward along the second guide member 13 to reset. At the same time, the first crank 81 of the crank common part 8 rotates forward synchronously through the first connecting rod 6 to drive the first slider 3 to move vertically downward along the first guide member 2 to reset. The head 1 is disengaged from the unlocking handle of the door lock device, completing the reset of the manual unlocking device.

S1、确定屏蔽门上的门锁装置的位置，并以此确定门锁装置的解锁转柄的输入端所在垂线L的位置；S1. Determine the position of the door lock device on the shielding door, and thereby determine the position of the vertical line L where the input end of the unlocking handle of the door lock device is located;
S2、确定滑动门的解锁顶杆的轴线L’的位置；S2, determining the position of the axis L' of the unlocking push rod of the sliding door;
S3、得出L与L’之间的距离h；S3, obtain the distance h between L and L';
S4、准备安装座4，在安装座4上分别安装第一导向件2与第二导向件13，第一导向件2的中轴线与第二导向件13的中轴线距离为h；S4, prepare the mounting seat 4, and respectively mount the first guide member 2 and the second guide member 13 on the mounting seat 4, wherein the distance between the central axis of the first guide member 2 and the central axis of the second guide member 13 is h;
S5、确定门锁装置的解锁行程x，确定解锁顶杆的最大移动行程y；S5, determining the unlocking stroke x of the door lock device and the maximum moving stroke y of the unlocking push rod;
S6、设计V型的曲柄共用件8，其中V型的曲柄共用件8的两条边分别为第一曲柄81与第二曲柄82，第一曲柄81长度为m，第二曲柄82长度为n，使m/n≥x/y；S6. Design a V-shaped crank common member 8, wherein two sides of the V-shaped crank common member 8 are a first crank 81 and a second crank 82, respectively. The length of the first crank 81 is m, and the length of the second crank 82 is n, such that m/n≥x/y;
S7、通过软件模拟装配：在第一导向件2内滑动安装第一滑块3，第一滑块3上端固定连接顶头1作为输出端，第一滑块3铰接合适长度的第一连杆6一端，第一连杆6另一端铰接第一曲柄81一端；在第二导向件13内滑动安装第二滑块14，第二滑块14下端固定连接圆盘15作为输入端，第二滑块14铰接合适长度的第二连杆12一端，第二连杆12另一端铰接第二曲柄82一端；S7, simulate assembly through software: slide the first slider 3 in the first guide member 2, the upper end of the first slider 3 is fixedly connected to the head 1 as the output end, the first slider 3 is hinged to one end of the first connecting rod 6 of appropriate length, and the other end of the first connecting rod 6 is hinged to one end of the first crank 81; slide the second slider 14 in the second guide member 13, the lower end of the second slider 14 is fixedly connected to the disk 15 as the input end, the second slider 14 is hinged to one end of the second connecting rod 12 of appropriate length, and the other end of the second connecting rod 12 is hinged to one end of the second crank 82;
S8、模拟装配完成后，进行模拟动作测试，使第二滑块14在第二导向件13内位移距离q，从而带动第一滑块3在第一导向件2内位移距离p，当p/q＜x/y时，重新设计曲柄共用件8，在原有的基础上增大m的值或减小n的值，并回到步骤S7，当p/q≥x/y时，进入下一步；S8, after the simulated assembly is completed, a simulated action test is performed to make the second slider 14 move a distance q in the second guide member 13, thereby driving the first slider 3 to move a distance p in the first guide member 2. When p/q＜x/y, the crank common member 8 is redesigned, the value of m is increased or the value of n is decreased on the original basis, and the process returns to step S7. When p/q≥x/y, the process proceeds to the next step.
S9、完成设计并依据设计结果生产制造，将安装座4通过螺栓组件5安装在合适位置，使得顶头1抵靠门锁装置的解锁转柄的输入端；使得圆盘15抵靠解锁顶杆的头端。S9. Complete the design and manufacture according to the design results. Install the mounting seat 4 at a suitable position through the bolt assembly 5 so that the top head 1 abuts against the input end of the unlocking handle of the door lock device; and the disc 15 abuts against the head end of the unlocking push rod.
上述的软件模拟装配及模拟动作测试可以通过现有的多种软件实现，如UE、SolidWorks等，使用方法属于本领域技术人员的常识，这里不再赘述。The above-mentioned software simulation assembly and simulation action test can be implemented by various existing software, such as UE, SolidWorks, etc. The usage method belongs to the common sense of those skilled in the art and will not be repeated here.
由于需要考虑偏心的问题使得第一连杆6与第二连杆12的长度不确定，就使得难以通过m与n的比值直接确定p与q的比值，所以上述方法中多次调整曲柄共用件8是为了使行程缩放机构的缩放系数更接近于门锁装置的解锁行程与滑动门解锁顶杆的最大移动行程之比，但实际上，只需p/q＞x/y即可，所以推荐实际设计时直接选用m/n＞2*x/y，可以使得结果更容易成立。Since the eccentricity problem needs to be considered, the lengths of the first connecting rod 6 and the second connecting rod 12 are uncertain, making it difficult to directly determine the ratio of p to q through the ratio of m to n. Therefore, the crank common part 8 is adjusted multiple times in the above method to make the scaling factor of the stroke scaling mechanism closer to the ratio of the unlocking stroke of the door lock device and the maximum moving stroke of the unlocking push rod of the sliding door. But in fact, only p/q＞x/y is required. Therefore, it is recommended to directly select m/n＞2*x/y in actual design, which can make the result easier to establish.
以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的技术人员来说，在不脱离本发明整体构思前提下，还可以作出若干改变和改进，这些也应该视为本发明的保护范围。The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
