Description

Technical Field

[0001] Generally speaking, the present invention relates to the technical field of locomotive production and manufacturing. Specifically, it relates to an auxiliary installation device for a coupler buffer. Background Art

[0002] A coupler buffer is a component that can transmit traction force and braking force and mitigate longitudinal impact force between locomotives or multiple units. The coupler buffer includes a connecting body, a front follower plate, a rear follower plate, a restoring block, a coupler tail pin, rubber piles, and process pads. There are the following defects in the installation of existing coupler buffers;

[0003] First, the coupler buffer and the collision box are jointly placed between the inner compartments of the coupler box partition. The inner compartment is 590 mm, and the distance between the front end face and the rear end face of the collision box is 240 mm. Therefore, the distance between the rear end face of the front follower plate in contact with the coupler box partition and the front end face of the rear follower plate should be less than 348 mm, so as to ensure the smooth installation of the coupler buffer.

[0004] Second, the installation position of the coupler buffer is at the lower end of the underframe. It is necessary to lift the coupler buffer to its installation position for direct installation by a lift. At this time, it is difficult to see the gap between the coupler buffer and its installation position, and it is difficult to determine the adjustment direction and size. Moreover, when adjusting, it is necessary to move the position of the lift to complete the installation of the coupler buffer, and the installation difficulty and intensity are relatively large.

[0005] Third, a process pad is arranged between the connecting body and the front follower plate of the coupler buffer. The process pad ensures that the distance between the rear end face of the front follower plate and the front end face of the rear follower plate is 350 mm. At the same time, the thickness and roughness of the process pad are used to fix the position of the rubber pile assembly in the connecting body, preventing the rubber pile from sliding in the connecting body during the transportation of the coupler buffer and affecting the linkage effect of the collision box, coupler, and coupler buffer during the later operation of the locomotive.

[0006] After the installation of the coupler buffer is completed, during the trial operation of the locomotive, the huge impact force generated by the violent swing of the coupler acts on the connecting body of the coupler buffer, resulting in the fragmentation of the process pad in contact with the connecting body and falling out of the coupler buffer. After many tests, there are still some fragments of the process pad remaining inside the coupler buffer, and the remaining fragments of the process pad affect the coupler swing angle after testing. Summary of the Invention

[0007] The auxiliary installation device for a coupler buffer provided by the present invention meets the installation dimension requirements and is convenient for taking out the pads.

[0008] According to the first aspect of the present invention, a coupler buffer auxiliary installation device is provided. The coupler buffer includes a connection frame and a front follower plate, a rear follower plate, a rubber stack, a cushion block, an installation part, and a hook tail pin provided on the connection frame. The rubber stack is arranged between the front follower plate and the rear follower plate. The cushion block is arranged between the front follower plate and the inner wall of the connection frame. The installation part is arranged outside the connection frame. The hook tail pin penetrates through the installation part. The coupler buffer auxiliary installation device includes:

[0009] An installation tooling, including a fixed bracket, a force control mechanism, and a thrust mechanism. The fixed bracket is detachably connected to the hook tail pin of the coupler buffer. The force control mechanism penetrates through the fixed bracket. The thrust mechanism is arranged inside the fixed bracket;

[0010] An expansion driving source is arranged between the force control mechanism and the thrust mechanism. One end of the expansion driving source can abut against the force control mechanism, and the other end pushes the thrust mechanism to insert into the installation part of the coupler buffer. By pushing the restoration block, the cushion block, and the front follower plate of the coupler buffer and pressing against the rubber stack of the coupler buffer, it is used to take out the cushion block between the front follower plate and the connection frame and adjust the distance between the front follower plate and the rear follower plate of the coupler buffer.

[0011] In some embodiments, the fixed bracket includes two fixed members arranged in parallel at intervals. The hook tail pin of the coupler buffer penetrates through the fixed members.

[0012] In some embodiments, the fixed member is provided with an installation hole. The hook tail pin of the coupler buffer penetrates through the installation hole and is detachably connected to the fixed member.

[0013] In some embodiments, the fixed bracket further includes two limit members arranged in parallel at intervals. The limit members are vertically arranged between the two fixed members. The force control mechanism penetrates through the limit members. The thrust mechanism is arranged between the two fixed members and the two limit members.

[0014] In some embodiments, the limit member is provided with an installation through hole. The force control mechanism penetrates through the installation through hole and is detachably connected to the limit member.

[0015] In some embodiments, four limit strips are respectively arranged at the four corners of the force control mechanism. The limit strips are used for limiting between the force control mechanism and the limit member.

[0016] In some of these embodiments, the installation through-hole has a rectangular hole structure, the cross-section of the force control mechanism is a square structure, and the force control mechanism is configured to be rotatable relative to the installation through-hole for switching between a locked state and an unlocked state between the force control mechanism and the limiting member.

[0017] In some of these embodiments, the thrust mechanism includes a connecting plate and two push plates. The two push plates are arranged in parallel at intervals, the connecting plate is arranged between the two push plates, and the expansion driving source can abut against the connecting plate and push the push plates to move in a direction close to or away from the restoring block of the coupler buffer through the connecting plate.

[0018] In some of these embodiments, the push plate is provided with an avoidance groove for avoiding the tail coupler pin.

[0019] In some of these embodiments, the installation tooling further includes a limiting mechanism, and the limiting mechanism is arranged in the fixed bracket and between the thrust mechanism and the fixed bracket.

[0020] In some of these embodiments, the limiting mechanism includes:

[0021] A first limiting block arranged on the bottom surface of the thrust mechanism;

[0022] Two second limiting blocks arranged on the bottom surface of the thrust mechanism and on both sides of the first limiting block. The first limiting block and the two second limiting blocks are arranged in a triangle for vertical central limiting of the thrust mechanism;

[0023] Two third limiting blocks arranged on the bottom surface of the thrust mechanism and on both sides of the second limiting block for horizontal limiting of the thrust mechanism.

[0024] One embodiment of the present invention has the following advantages or beneficial effects:

[0025] The auxiliary installation device for the coupler buffer provided in this embodiment uses the tail pin of the coupler buffer to pass through and fix the support bracket, so as to fix the entire installation tooling on the coupler buffer. The expansion drive source is arranged between the force control mechanism and the thrust mechanism. By controlling the movement range between the force control mechanism and the thrust mechanism, the pressure of the expansion drive source is forced to act entirely on the thrust mechanism. The thrust mechanism inserts into the installation part of the coupler buffer. When the pressure reaches a certain level, the thrust mechanism sequentially pushes the restoration block, the cushion block and the front yoke plate of the coupler buffer and presses against the rubber stack of the coupler buffer, making the rubber stack in a compressed state. At this time, the cushion block is in a loose state, which is convenient for the cushion block to be taken out from between the front yoke plate and the inner wall of the connection frame, avoiding the situation that the cushion block is easily broken under the action of a huge impact force and remains inside the coupler buffer, affecting the swing angle of the coupler, thereby ensuring the safety of the coupler during use. At the same time, under the combined action of the installation tooling and the expansion drive source, while quickly completing the installation of the coupler buffer, the labor intensity of the operator is reduced, the efficiency is improved, and the labor and production costs are saved. The auxiliary installation device for the coupler buffer has a simple structure, is easy to install and disassemble, and improves the production quality and production efficiency.

[0026] In addition, in the auxiliary installation device for the coupler buffer, the thrust mechanism squeezes the restoration block. The thrust mechanism is subjected to the extrusion force after the expansion of the expansion drive source. The rear end circular surface of the hydraulic jack after expansion squeezes the front end surface of the force control mechanism. At this time, since the force control mechanism is fixed relative to the support bracket, the expansion pressure of the hydraulic jack acts entirely on the thrust mechanism, making the size of the coupler buffer meet the installation requirements.

[0050] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their detailed description will be omitted.

[0051] This embodiment provides an auxiliary installation device for a coupler buffer, which is used for the installation of the coupler buffer 100. The coupler buffer 100 is specifically a type 102 coupler buffer. Among them, as Figures 1 - 3As shown in the figure, the coupler buffer 100 includes a connection frame 101, a front follower plate 102, a rear follower plate 103, a rubber stack 104, a spacer 105, a mounting portion 106, and a coupler tail pin 107 disposed on the connection frame 101. The rubber stack 104 is disposed between the front follower plate 102 and the rear follower plate 103. The spacer 105 is disposed between the front follower plate 102 and the inner wall of the connection frame 101. The mounting portion 106 is disposed outside the connection frame 101. The coupler tail pin 107 passes through the mounting portion 106.

[0052] Since the rubber stack 104 has a certain elasticity, in order to prevent the rubber stack 104 from pushing the front follower plate 102 and the rear follower plate 103 to move to both sides of the rubber stack 104, causing the front follower plate 102 to abut against the inner wall of the connection frame 101 and resulting in hard bruises between the front follower plate 102 and the connection frame 101, before the coupler buffer 100 is installed on the vehicle frame, a spacer 105 is disposed between the front follower plate 102 and the connection frame 101. The spacer 105 can also be called a process spacer, which plays a role of intermediate isolation between the front follower plate 102 and the connection frame 101. When the locomotive is running, under the action of a huge impact force, the spacer 105 is prone to breakage. It is possible that a part of the spacer 105 falls outside the coupler buffer 100, and another part of the spacer 105 remains inside the coupler buffer 100, thus affecting the swing angle of the coupler 300.

[0053] To solve this problem, the present embodiment provides an auxiliary installation device for a coupler buffer, as Figure 4 shown. The auxiliary installation device for the coupler buffer includes an installation tooling and an expansion driving source (not shown in the figure). The installation tooling includes a fixed bracket 1, a force control mechanism 2, and a thrust mechanism 3. The fixed bracket 1 is detachably connected to the coupler tail pin 107 of the coupler buffer 100. The force control mechanism 2 passes through the fixed bracket 1. The thrust mechanism 3 is disposed inside the fixed bracket 1. The expansion driving source is disposed between the force control mechanism 2 and the thrust mechanism 3. One end of the expansion driving source can abut against the force control mechanism 2, and the other end pushes the thrust mechanism 3 to insert into the mounting portion 106 of the coupler buffer 100. By pushing the restoration block 108, the spacer 105, and the front follower plate 102 of the coupler buffer 100 and pressing against the rubber stack 104 of the coupler buffer 100, it is used to take out the spacer 105 between the front follower plate 102 and the connection frame 101 and adjust the distance between the front follower plate 102 and the rear follower plate 103 of the coupler buffer 100.

[0054] It can be understood that the expansion driving source can specifically be a hydraulic jack, or the collision driving source can be other driving structures capable of providing expansion driving.

[0055] The coupler buffer auxiliary installation device provided in this embodiment utilizes the coupler tail pin 107 of the coupler buffer 100 to penetrate the fixing bracket 1, thereby securing the entire installation device to the coupler buffer 100. An expansion drive source is disposed between the force control mechanism 2 and the thrust mechanism 3. By controlling the range of motion between the force control mechanism 2 and the thrust mechanism 3, the pressure of the expansion drive source is forced to act entirely on the thrust mechanism 3, which is then inserted into the mounting portion 106 of the coupler buffer 100. When the pressure reaches a certain level, the thrust mechanism 3 sequentially pushes the recovery block 108, the cushion block 105, and the front follower plate 102 of the coupler buffer 100 against the rubber pile 104 of the coupler buffer 100, compressing the rubber pile 104. At this point, the cushion block 105 is loose, making it easier to remove it from between the front follower plate 102 and the inner wall of the connecting frame 101. This prevents the cushion block 105 from breaking under the impact force, which could cause it to remain inside the coupler buffer 100 and affect the swing angle of the coupler 300, thereby ensuring the safety of the coupler 300. Furthermore, the combined action of the installation tool and the expansion drive source allows for rapid installation of the coupler buffer 100 while reducing operator labor intensity, improving efficiency, and saving labor and production costs. The coupler buffer auxiliary installation device has a simple structure, is easy to install and remove, and improves production quality and efficiency.

[0056] It should be noted that if Figures 4 - 5 As shown, the coupler buffer 100 and the crash box 200 need to be fixed together and placed in the inner section of the coupler box partition, which has a minimum inner section of 588 mm. The distance between the front and rear faces of the crash box 200 is 240 mm. Therefore, the distance between the coupler buffer 100 and the coupler box partition should be less than 348 mm to ensure smooth installation of the coupler buffer 100. To this end, the front face of the thrust mechanism 3 in the coupler buffer auxiliary installation device squeezes the rear face of the restoration block 108. The rear face of the thrust mechanism 3 is squeezed by the expanded front circular face of the hydraulic jack, which in turn squeezes the front face of the control mechanism 2. At this time, since the control mechanism 2 is fixed relative to the fixing bracket 1, the expansion pressure of the hydraulic jack acts on the thrust mechanism 3, so that the size of the coupler buffer 100 meets the installation size requirements.

[0057] In one embodiment, Figures 6 - 7 As shown, the fixing bracket 1 includes two fixing members 11 arranged in parallel and spaced apart, and the coupler tail pin 107 of the coupler buffer 100 is passed through the fixing members 11.

[0058] Since the two fixing members 11 are arranged in parallel at intervals, there is a certain distance space between the two fixing members 11. The hook tail pin 107 of the coupler buffer 100 is respectively passed through the fixing members 11 from top to bottom, and the hook tail pin 107 of the coupler buffer 100 itself is used to lock the fixing members 11. Using local materials, no additional fixing structure needs to be set, saving production costs.

[0059] It should be particularly noted that the front end of the fixing member 11 is approximately in a semi-circular structure, and the front ends of the two fixing members 11 can be respectively inserted into the inner file of the installation part 106 in the coupler buffer 100. Among them, the distance between the two fixing members 11 is less than the distance between the upper end face and the lower end face of the inner file, so that the front end of the fixing member 11 can be inserted into the inner file.

[0060] It should be particularly noted that a through slot hole is provided at the rear end of the fixing member 11, and the through slot hole reserves a certain installation space for the air pipe of the expansion driving source.

[0061] In one embodiment, as Figures 6 - 7 shown, the fixing member 11 is provided with an installation hole 111, and the hook tail pin 107 of the coupler buffer 100 is passed through the installation hole 111 and is detachably connected to the fixing member 11.

[0062] Among them, an installation hole 111 is provided in the fixing member 11, and the installation hole 111 is in a circular hole structure, so that the front end of the fixing member 11 is similar to a semi-concentric ring structure. The diameter of the installation hole 111 is slightly larger than the diameter of the hook tail pin 107, which is convenient for fixing the entire auxiliary installation device of the coupler buffer to the coupler buffer 100 through the fixing member 11 and the hook tail pin 107, facilitating the installation of the coupler buffer 100. The diameter of the installation hole 111 is less than or equal to the distance between the left end face and the right end face of the fixing member 11.

[0063] In one embodiment, as Figures 6 - 7 shown, the fixing bracket 1 further includes two limiting members 12 arranged in parallel at intervals. The limiting members 12 are vertically arranged between the two fixing members 11, the force control mechanism 2 is passed through the limiting members 12, and the thrust mechanism 3 is arranged between the two fixing members 11 and the two limiting members 12.

[0064] The two fixing members 11 are arranged in parallel at intervals, and the two limiting members 12 are arranged in parallel at intervals and vertically arranged between the two fixing members 11, so that the two fixing members 11 and the two limiting members 12 enclose a rectangular frame structure. The internal space of the rectangular frame structure provides an accommodation space for the thrust mechanism 3, so that the thrust mechanism 3 is arranged between the two fixing members 11 and the two limiting members 12. Both ends of the force control mechanism 2 can be respectively passed through the two limiting members 12, and the force control mechanism 2 and the thrust mechanism 3 are arranged at intervals to place the expansion driving source between the force control mechanism 2 and the thrust mechanism 3.

[0065] It is understood that the distance between the mounting hole 111 of the fixing member 11 and the rear end surface of the fixing member 11 is greater than the sum of the distance between the front end surface of the control mechanism 2 and the rear end surface of the stopper 12, the distance between the front and rear ends of the thrust mechanism 3, and the distance between the front and rear ends of the expansion drive source. This allows for sufficient space for the expansion drive source to facilitate placement of the unexpanded expansion drive source and assembly with the control mechanism 2. However, this distance should not be too large, as otherwise it could easily cause the expansion drive source to misalign its position in relation to the thrust mechanism 3, thereby affecting the functionality of the expansion drive source.

[0066] It can be understood that the front end faces of the two fixing members 11 are flush with the front end faces of the two limiting members 12, the upper end faces and the lower end faces of the two limiting members 12 are flush with the two outer side faces of the two fixing members 11 respectively, and the left and right side faces of the two fixing members 11 are flush with the inner side faces of the two limiting members 12 respectively, that is, the two fixing members 11 and the two limiting members 12 are connected end to end to form a rectangular through groove.

[0067] It can be understood that the edges on the left and right sides of the outer side surface of the fixing member 11 are respectively provided with a groove, the groove is a V-shaped structure, the length of the groove is slightly larger than the distance between the front end face and the rear end face of the limiting member 12, and the groove extends to a position approximately at the front end face of the fixing member 11.

[0068] In one embodiment, Figures 6 - 7 As shown, the limiting member 12 is provided with a mounting through hole 121 , and the force control mechanism 2 is passed through the mounting through hole 121 and is detachably connected to the limiting member 12 .

[0069] Among them, the mounting hole 121 is located at the center of the limiting member 12, and the mounting hole 121 is a rectangular hole structure. The distance between the upper end surface and the lower end surface of the mounting hole 121 is slightly larger than the distance between the upper end surface and the lower end surface of the control mechanism 2.

[0070] In one embodiment, Figures 6 - 8 As shown, four limiting strips 21 are respectively provided at the four corners of the force control mechanism 2 , and the limiting strips 21 are used for limiting the position between the force control mechanism 2 and the limiting member 12 .

[0071] Among them, the force control mechanism 2 is of a cuboid structure. Specifically, the force control mechanism 2 includes two relatively arranged first side faces and four second side faces. The first side face is of a square structure, and the four second side faces are connected end to end and arranged between the two first side faces. At both ends of one of the two relatively arranged second side faces close to the first side face, two limiting strips 21 are respectively arranged. At both ends of the other of the two relatively arranged second side faces close to the first side face, two limiting strips 21 are respectively arranged. That is, four limiting strips 21 are correspondingly arranged at the left and right ends of the two relatively arranged second side faces and close to the four corners. The four limiting strips 21 are all used for the limitation between the force control mechanism 2 and the limiting member 12. The four limiting strips 21 are symmetrically arranged along the horizontal center line of the force control mechanism 2 respectively, and the four limiting strips 21 are symmetrically arranged along the vertical center line of the force control mechanism 2 respectively. After the force control mechanism 2 passes through the installation through hole 121, the four limiting strips 21 can be used to prevent the force control mechanism 2 from disengaging from the installation through hole 121.

[0072] In one embodiment, the installation through hole 121 is of a rectangular hole structure, and the cross section of the force control mechanism 2 is of a square structure. The force control mechanism 2 is configured to be able to rotate relative to the installation through hole 121 for switching between a locked state and an unlocked state between the force control mechanism 2 and the limiting member 12.

[0073] Among them, since the first side face of the force control mechanism 2 is of a square structure and the four side lengths of the first side face are the same, the installation through hole 121 is of a rectangular hole structure, the long side of the installation through hole 121 is greater than the side length of the first side face, and even 1 / 2 times the long side of the installation through hole 121 is greater than the side length of the first side face, and the short side of the installation through hole 121 is slightly greater than or approximately equal to the side length of the first side face.

[0074] When the force control mechanism 2 passes through the installation through hole 121, if the limiting strips 21 respectively correspond to the long side of the installation through hole 121, the four limiting strips 21 are respectively arranged on the outer side faces of the two limiting members 12, playing a role in limiting between the limiting member 12 and the force control mechanism 2. The force control mechanism 2 and the limiting member 12 are in a locked state, preventing the force control mechanism 2 from disengaging from the installation through hole 121. If the expansion driving source is started, both sides of the collision driving source are respectively abutted against the force control mechanism 2 and the thrust mechanism 3, enabling the force control mechanism 2 to slide along the long side of the installation through hole 121 to the end far from the thrust mechanism 3 and reach the limit position.

[0075] If the force control mechanism 2 needs to be removed from the installation through hole 121, first rotate the force control mechanism 2 relative to the installation through hole 121 so that the four limiting strips 21 respectively correspond to the short side of the installation through hole 121. At this time, the length of the long side of the installation through hole 121 is greater than the side length of the first side face in the force control mechanism 2 and the width of the two limiting strips 21. The force control mechanism 2 and the limiting member 12 are in an unlocked state, enabling the force control mechanism 2 to be withdrawn from the installation through hole 121.

[0076] In this way, the force control mechanism 2 and the limit member 12 can switch freely between the locked state and the unlocked state, which can ensure the stability of the relative position of the force control mechanism 2 and the limit member 12 in the unlocked state and facilitate the installation and disassembly of the force control mechanism 2.

[0077] In one embodiment, Figures 6 - 8 As shown, the thrust mechanism 3 includes a connecting plate 31 and two push plates 32. The two push plates 32 are arranged in parallel and spaced apart. The connecting plate 31 is arranged between the two push plates 32. The expansion drive source can abut against the connecting plate 31 and push the push plate 32 to move toward or away from the recovery block 108 of the coupler buffer 100 through the connecting plate 31.

[0078] The two push plates 32 are arranged in parallel and spaced apart, and the front ends of the two push plates 32 are respectively inserted into the inner gear of the coupler buffer 100, and the connecting plate 31 is arranged between the two push plates 32. The connecting plate 31 serves as an intermediate connection between the two push plates 32. After the expansion driving source expands, the connecting plate 31 provides a force position for the expansion driving source, so that the expansion driving source pushes the push plate 32 to move toward the direction of the coupler buffer 100 through the connecting plate 31. After the push plate 32 is inserted into the inner gear, it pushes the recovery block 108 to move and compresses the rubber pile 104.

[0079] The rear end faces of the two push plates 32 are coplanar with the rear end face of the connecting plate 31, the left end faces of the two push plates 32 are coplanar with the left end face of the connecting plate 31, and the right end faces of the two push plates 32 are coplanar with the right end face of the connecting plate 31, and the two push plates 32 are respectively fixed to the upper end face and the lower end face of the connecting plate 31 to form a weight-reducing groove between the connecting plate 31 and the two push plates 32. The distance between the upper end face and the lower end face of the weight-reducing groove is greater than the distance between the upper end face and the lower end face of the lock tongue in the rear end part of the coupler buffer 100. The weight-reducing groove plays a role in reducing the overall weight of the coupler buffer auxiliary installation device to meet the lightweight requirements.

[0080] In one embodiment, Figures 6 - 8 As shown, the push plate 32 is provided with an avoidance groove 321 , and the avoidance groove 321 is used to avoid the hook tail pin 107 .

[0081] Since the two push plates 32 and the two fixing parts 11 are parallel to each other, the hook tail pin 107 is passed through the mounting hole 111 of the fixing part 11. An avoidance groove 321 is provided at a position corresponding to the mounting hole 111 of the push plate 32. The avoidance groove 321 is used to avoid the hook tail pin 107, so that the hook tail pin 107 can pass through the mounting hole 111 and the avoidance groove 321 from top to bottom, which is convenient for fixing the entire coupler buffer auxiliary mounting device and the coupler buffer 100.

[0082] Among them, the shape of the avoidance groove 321 is adapted to the outer shape of the hook tail pin 107. The avoidance groove 321 is similar to a semi-circular structure, so that the front end face of the push plate 32 has an arc portion and two flat portions. The two flat portions are respectively arranged on both sides of the arc portion. The radius of the arc portion is less than 2 / 3 of the distance between the front end face and the rear end face of the push plate 32, and the radius of the arc portion is greater than the sum of the distance between the central axis of the hook tail pin 107 of the coupler buffer 100 and the front end face of the restoration block 108 and the radius of the mounting hole 111 of the fixing member 11.

[0083] In one embodiment, as Figures 6 - 8 shown, the installation tooling further includes a limiting mechanism 4. The limiting mechanism 4 is arranged in the fixing bracket 1 and between the thrust mechanism 3 and the fixing bracket 1. With this arrangement, the limiting between the push plate 32 of the thrust mechanism 3 and the fixing member 11 of the fixing bracket 1 can be realized to ensure the vertical state of the thrust mechanism 3.

[0084] In one embodiment, the limiting mechanism 4 includes a first limiting block 41 and two second limiting blocks 42. The first limiting block 41 is arranged on the bottom surface of the thrust mechanism 3. The two second limiting blocks 42 are arranged on the bottom surface of the thrust mechanism 3 and on both sides of the first limiting block 41. The first limiting block 41 and the two second limiting blocks 42 are arranged in a triangular shape.

[0085] Among them, the first limiting block 41 is arranged at a position close to the rear end face of the push plate 32. The distance between the upper end face and the lower end face of the three limiting blocks, namely the first limiting block 41 and the two second limiting blocks 42, is the same. The first limiting block 41 and the two second limiting blocks 42 are arranged in a triangular shape to jointly squeeze the push plate 32 and be able to control the vertical position of the connecting plate 31. The front end face of the second limiting block 42 is flush with the front end face of the push plate 32 and is arranged along the edge of the avoidance groove 321.

[0086] Two third limiting blocks 43 are arranged on the bottom surface of the thrust mechanism 3. The distance between the upper end face and the lower end face of the two third limiting blocks 43 is the same. The two third limiting blocks 43 are arranged on both sides of the second limiting block 42. The two third limiting blocks 43 are symmetrically arranged along the neutral plane of the first limiting block 41. The front end face of the third limiting block 43 is flush with the front end face of the push plate 32. The inner side surface of the third limiting block 43 is attached to the side surface of the push plate 32, that is, the distance between the inner side surfaces of the two third limiting blocks 43 on the side close to each other is slightly greater than the distance between the left and right end faces of the push plate 32 of the thrust mechanism 3, for the horizontal limiting of the thrust mechanism 3.

[0087] The working process of the coupler buffer auxiliary installation device provided in this embodiment is as follows:

[0088] After removing the hook tail pin 107 of the coupler buffer 100, assemble the remaining components of the auxiliary installation device for the coupler buffer except for the force control mechanism 2 and insert them into the rear end of the coupler buffer 100. Then, pass the previously removed hook tail pin 107 through the fixing members 11 of the fixing bracket 1 respectively to fixedly install the auxiliary installation device for the coupler buffer on the coupler buffer 100 (as Figure 4 shown);

[0089] Then, place the expansion driving source inside the fixing bracket 1 and insert the force control mechanism 2 into the installation through holes 121 of the two limiting members 12, so that the collision driving source is located between the force control mechanism 2 and the thrust mechanism 3 to limit the position of the collision driving source;

[0090] The operator reciprocally turns the crank of the expansion driving source. After expansion, one end of the expansion driving source can abut against the force control mechanism 2, and the other end pushes the thrust mechanism 3 to insert into the installation part 106 of the coupler buffer 100. By pushing the restoring block 108, the cushion block 105 and the front yoke plate 102 of the coupler buffer 100 and pressing against the rubber stack 104 of the coupler buffer 100, the cushion block 105 can be taken out from between the front yoke plate 102 and the connecting frame 101 with a slender tool;

[0091] Lift and transport the coupler buffer 100 and the entire auxiliary installation device for the coupler buffer to the underframe turntable with a sling. Adjust the lower end of the locomotive underframe to the upper surface through the underframe turntable to install the coupler buffer 100 in reverse, reducing the installation difficulty and facilitating observing the gap between the coupler buffer 100 and its installation position, and facilitating determining the adjustment direction and dimensions (as Figure 5 shown), so as to complete the installation of the coupler buffer 100;

[0092] Place the wear plate 400 on the upper end of the installed coupler buffer 100 with a sling (as Figure 9 shown), and fixedly connect the wear plate 400, the coupler buffer 100 and the coupler box partition with bolts;

[0093] Finally, open the oil return valve of the expansion driving source, and the hydraulic jack returns to pressure. At this time, the force control mechanism 2 can be taken out, then the hydraulic jack can also be taken out, and then the remaining components of the auxiliary installation device for the coupler buffer are taken out, thus completing the removal of the auxiliary installation device for the coupler buffer.
