Description

Technical Field

[0001] This utility model relates to the field of coupler maintenance technology, and more specifically, to a coupler maintenance fixture. Background Technology

[0002] Couplers are important connecting components on railway vehicles, locomotives, or other equipment. They come in various types and have different functions. A coupler is a hook at both ends of a train car or locomotive, used to connect locomotives and cars or cars and cars, transmit traction and impact forces, and maintain a certain distance between cars.

[0003] Coupler maintenance fixtures are tools or equipment used to assist in the maintenance of couplers on railway vehicles, locomotives, or other equipment. During the maintenance process, coupler maintenance fixtures can provide stable support and fixation for the couplers. They can also be used to move the couplers to prevent them from accidentally falling or moving during maintenance, thus reducing the risk of injury to maintenance personnel. In addition, some fixtures may be equipped with protective devices such as protective covers and chip baffles to further ensure the personal safety of maintenance personnel.

[0004] During coupler maintenance, the coupler assembly is disassembled and placed in a coupler maintenance fixture before being transported to the cleaning area for cleaning. High-pressure water guns are used to wash away the grease and grime from the surfaces of the components. Because the coupler assembly comprises components of various shapes, sizes, and weights, such as the coupler itself, the coupler tail frame, and the buffer, even if these components are neatly arranged before transport, they inevitably shake and vibrate during the movement of the coupler maintenance fixture, especially when it is moved to uneven or bumpy sections. This shaking can cause collisions between adjacent components, potentially damaging their appearance, such as causing paint peeling or scratches. For components with high precision requirements, it can also affect their dimensional accuracy and performance.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a coupler maintenance fixture. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coupler maintenance tool.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coupler maintenance fixture, comprising a transfer frame and a stabilizing component disposed on the transfer frame. The stabilizing component includes slide rails. Two slide rails are symmetrically arranged inside the transfer frame. Multiple clamping plates A are slidably installed in the two slide rails. Each clamping plate A is symmetrically mounted with a support rod. Each support rod is mounted with a support block. Each support block has a moving groove. A limiting plate is slidably installed in each moving groove. Each limiting plate passes through the support block and is connected to the support block by a spring A. Multiple limiting grooves are symmetrically arranged inside the transfer frame, and each limiting plate can slide in the corresponding limiting groove.

[0008] Each of the clamping plates A is provided with a sliding groove, and a slider is slidably installed in each sliding groove. Each slider is symmetrically slidably installed with a limit rod. Each limit rod is connected to the sliding groove by a spring B. Each clamping plate A is symmetrically provided with multiple limit holes, and each limit rod can slide in the corresponding limit hole.

[0009] Each slider is equipped with a support plate, each support plate is equipped with a screw, each screw is equipped with a stabilizing plate at the end near the bottom of the transfer frame, and each stabilizing plate is equipped with an anti-collision pad.

[0010] Preferably, each of the clamping plates A is symmetrically provided with a buffer assembly, each buffer assembly includes a spring C, and one end of multiple springs C is installed on both sides of each of the clamping plates A. The other end of each spring C is connected to a clamping plate B. Each of the clamping plates B is provided with an anti-slip pad, which facilitates the buffer protection of the coupler parts, effectively disperses and consumes the impact force, reduces friction and collision between coupler parts, and reduces the wear of these parts.

[0011] Preferably, the multiple support plates on each clamp A are staggered to facilitate fixing the coupler parts on both sides of the clamp A.

[0012] Preferably, each spring C is installed at equal intervals, which makes it easier to distribute the impact force more evenly to each spring C, rather than having a single or a few spring C bear most of the impact force. This can prevent local spring C from being damaged prematurely due to excessive force, extend the overall service life of the spring C, and ensure the stability and reliability of the coupler during buffering.

[0013] Preferably, the lower end of the transfer frame is equipped with multiple symmetrical connecting frames, each of which is rotatably mounted with a roller to facilitate movement.

[0014] Preferably, a support frame is installed on the transfer frame, and multiple hooks are installed on the support frame to facilitate the hanging of vehicle coupler parts.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, by using a stabilizing component set on the transfer frame, when moving the coupler parts within the transfer frame, to ensure the stability of the coupler parts, first, the limiting plates at both ends of one of the clamping plates A are grasped and the two limiting plates are moved into the clamping plate A. At this time, the two limiting plates will move in the corresponding moving groove and compress the connected spring A until both limiting plates are disengaged from their respective limiting grooves. Then, the clamping plate A is moved to the appropriate position in the slide rail, and then the two limiting plates are released. At this time, the connected spring A will push the corresponding limiting plate back into the corresponding limiting groove through its elasticity, thereby fixing the clamping plate A. Then, the remaining clamping plates A are moved to the appropriate position in the same way. At this time, the coupler will be fixed by every two adjacent clamping plates A.

[0017] Next, grasp the two limiting rods on one of the sliders and move them upwards. As the limiting rods move upwards, they stretch the connected spring B until both limiting rods disengage from their corresponding limiting slots. Then, move the slider to the appropriate position within the slot and release the two limiting rods. At this point, spring B will use its rebound properties to push the connected limiting rods back into their corresponding limiting holes, thus fixing the slider in place. Then, rotate the screw. As the screw rotates, it will move the stabilizing plate towards the coupler component until it is in contact with the coupler component. At this point, the stabilizing plate will fix the coupler component from above within the transfer frame. When the plate is in contact with the coupler parts, the anti-collision pads on the stabilizing plate will also be in contact with the coupler parts. In summary, the other sliders are moved to the appropriate positions, and then the coupler parts are fixed in the transfer frame from above by each stabilizing plate. This solves the problem in the background technology that during the movement of the coupler maintenance fixture, especially when the coupler maintenance fixture is moved to an uneven or bumpy road section, the shaking and vibration will inevitably occur. These shaking and vibrations will cause collisions between adjacent parts, which may damage the appearance of the parts, such as causing paint peeling, scratches, etc. For some parts with high precision requirements, it may also affect their dimensional accuracy and performance.

[0018] 2. In this utility model, through the buffer assembly set on the clamping plate B, when two adjacent clamping plates A are laterally fixed to the coupler parts, the clamping plates B on the adjacent clamping plates A will come into contact with the coupler parts. At this time, the two clamping plates B will buffer the coupler parts. When the two clamping plates B are in contact with the coupler parts, the anti-slip pads on each clamping plate B will play an anti-slip and buffering role. At the same time, each spring C connected to the clamping plate B will increase the buffering of the coupler parts, thereby achieving buffer protection for the coupler parts. It can effectively disperse and consume impact force, reduce friction and collision between coupler components, and reduce the wear of these components. Attached Figure Description

[0026] like Figure 1-5As shown, this utility model provides a coupler maintenance fixture, including a transfer frame 1 for storing coupler parts and a stabilizing component 6 on the transfer frame 1. When moving the coupler parts within the transfer frame 1, to ensure stability, the stabilizing components are first grasped by holding the limiting plates 606 at both ends of one of the clamping plates A602 and moving the two limiting plates 606 into the clamping plate A602. At this time, the two limiting plates 606 will move within their corresponding moving grooves 605 and compress the connected springs. Spring A607 is used until both limiting plates 606 are disengaged from their respective limiting grooves 617. Then, clamp A602 is moved to the appropriate position in slide rail 601. Then, the two limiting plates 606 are released. At this time, the connected spring A607 will push the corresponding limiting plate 606 back into the corresponding limiting groove 617 through its elasticity, thereby fixing clamp A602. Then, the remaining clamp A602 is moved to the appropriate position in the same way. At this time, the coupler will be fixed by every two adjacent clamps A602.

[0027] Next, grasp the two limiting rods 610 on one of the sliders 609 and move them upwards. As the two limiting rods 610 move upwards, they will stretch the connected spring B611 until both limiting rods 610 disengage from their corresponding limiting grooves 617. Then, move the slider 609 to the appropriate position within the slide groove 608. Release the two limiting rods 610. At this point, the spring B611 will, through its elasticity, push the connected limiting rods 610 back into their corresponding limiting holes 612, thus fixing the slider 609. Then, rotate the screw 614. When the screw 614... When 14 rotates, it will move the stabilizing plate 615 towards the coupler part until it is in contact with the coupler part. At this time, the stabilizing plate 615 will fix the coupler part in the transfer frame 1 from the top. When the stabilizing plate 615 is in contact with the coupler part, the anti-collision pad 616 on the stabilizing plate 615 will also be in contact with the coupler part. In summary, move the other sliders 609 to the appropriate position, and then fix the coupler part in the transfer frame 1 from the top through each stabilizing plate 615. This can effectively improve the stability of the coupler in the transfer frame 1 and avoid collisions between coupler parts.

[0028] The stabilizing component 6 includes slide rails 601. Two slide rails 601 are symmetrically arranged within the transfer frame 1 to ensure the stability of the sliding of each clamping plate A602. Multiple clamping plates A602 are slidably installed within the two slide rails 601 to achieve lateral fixation of the coupler connection. Each clamping plate A602 is symmetrically equipped with a support rod 603 for support and transmission. Each support rod 603 is equipped with a support block 604 for support. Each support block 604 has a moving groove 605 to ensure the stable sliding of the limiting plate 606. Each movable slot 605 has a slidable limiting plate 606 installed in it for fixing purposes. Each limiting plate 606 passes through the support block 604 and is connected to the support block 604 by a spring A607 for fixing the limiting plate 606 and automatically resetting it. Multiple limiting slots 617 are symmetrically opened on the inner side of the transfer frame 1 for fixing the clamping plate A602 in conjunction with the limiting plate 606. Each limiting plate 606 can slide in the corresponding limiting slot 617.

[0029] Each clamping plate A602 has a sliding groove 608 to ensure the stable sliding of the slider 609. A slider 609 is slidably installed in each sliding groove 608 to achieve transmission and support. Each slider 609 is symmetrically slidably installed with a limit rod 610 to achieve fixation. Each limit rod 610 is connected to its corresponding sliding groove 608 by a spring B611 to fix the limit rod 610 and enable the limit rod 610 to automatically reset. Each clamping plate A602 has multiple symmetrical limit holes 612 to cooperate with the limit rod 610 to fix the slider 609. Each limit rod 610 can slide in the corresponding limit hole 612.

[0030] Each slider 609 is equipped with a support plate 613, which serves to support the screw 614. Each support plate 613 is equipped with a screw 614, which serves to control the vertical movement of the clamping plate B702. Each screw 614 is equipped with a stabilizing plate 615 near the bottom of the transfer frame 1, which serves to increase friction and provide protection. Each stabilizing plate 615 is equipped with an anti-collision pad 616.

[0031] Each clamping plate A602 is symmetrically provided with a buffer assembly 7, which is used to achieve the following when two adjacent clamping plates A602 are laterally fixed to the coupler parts: the clamping plates B702 on the adjacent clamping plates A602 will fit together with the coupler parts. At this time, the two clamping plates B702 will buffer the coupler parts. When the two clamping plates B702 are in contact with the coupler parts, the anti-slip pads 703 on each clamping plate B702 will play an anti-slip and buffering role. At the same time, each spring C701 connected to the clamping plate B702 will increase the buffering of the coupler parts, thereby achieving buffering protection of the coupler parts, effectively dispersing and consuming impact force, reducing friction and collision between coupler components, and reducing the wear of these components.

[0032] Each buffer assembly 7 includes a spring C701 for cushioning. Multiple springs C701 are installed on one end of each side of each clamp A602. The other end of each spring C701 is connected to a clamp B702 for fixing. Each clamp B702 is equipped with an anti-slip pad 703 for reducing impact and protection.

[0033] The multiple support plates 613 on each clamp A602 are staggered, which are used to fix the coupler parts on both sides of the clamp A602.

[0034] Each spring C701 is installed at equal intervals, which is used to distribute the impact force more evenly to each spring C701, rather than having a single or a few springs C701 bear most of the impact force. This can prevent local springs C701 from being damaged prematurely due to excessive force, extend the overall service life of springs C701, and ensure the stability and reliability of the coupler during buffering.

[0035] Multiple symmetrical connecting frames 2 are installed at the lower end of the transfer frame 1. Each connecting frame 2 is rotatably mounted with a roller 3, which is used to facilitate the movement of the transfer frame.

[0036] A support frame 4 is installed on the transfer frame 1, which is used to support the hooks 5. Multiple hooks 5 are installed on the support frame 4, which are used to hang the car coupler parts.

[0037] Working principle: When moving the coupler parts within the transfer frame 1, to ensure stability, first grasp the limiting plates 606 at both ends of one of the clamping plates A602 and move the two limiting plates 606 into the clamping plate A602. At this time, the two limiting plates 606 will move within the corresponding moving groove 605 and compress the connected spring A607 until both limiting plates 606 are disengaged from their respective limiting grooves 617. Then, move the clamping plate A602 to the appropriate position within the slide rail 601 and release the two limiting plates 606. At this time, the connected spring A607 will push the corresponding limiting plate 606 back into the corresponding limiting groove 617 through its elasticity, thereby fixing the clamping plate A602. Then, move the remaining clamping plates A602 to the appropriate position in the same way. At this time, the coupler will be fixed by every two adjacent clamping plates A602.

[0038] Next, grasp the two limiting rods 610 on one of the sliders 609 and move them upwards. As the two limiting rods 610 move upwards, they stretch the connected spring B611 until both limiting rods 610 disengage from their corresponding limiting grooves 617. Then, move the slider 609 to the appropriate position within the slide groove 608. Release the two limiting rods 610. At this point, the spring B611 will, through its elasticity, push the connected limiting rods 610 back into their corresponding limiting holes 612, thereby moving the slider 609... Fix it, and then rotate the screw 614. When the screw 614 rotates, it will move the stabilizing plate 615 towards the coupler part until it is in contact with the coupler part. At this time, the coupler part will be fixed in the transfer frame 1 from the top by the stabilizing plate 615. When the stabilizing plate 615 is in contact with the coupler part, the anti-collision pad 616 on the stabilizing plate 615 will be in contact with the coupler part. In summary, move the other sliders 609 to the appropriate position, and then fix the coupler part in the transfer frame 1 from the top by each stabilizing plate 615.

[0039] When two adjacent clamping plates A602 are used to fix the coupler parts laterally, the clamping plates B702 on the adjacent clamping plates A602 will come into contact with the coupler parts. At this time, the two clamping plates B702 will buffer the coupler parts. When the two clamping plates B702 are in contact with the coupler parts, the anti-slip pads 703 on each clamping plate B702 will play an anti-slip and buffering role. At the same time, each spring C701 connected to the clamping plate B702 will increase the buffering of the coupler parts, thereby achieving buffering protection for the coupler parts.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
