This disassembly and assembly device allows for rapid disassembly and assembly of the end cap using the wrench module, resulting in high work efficiency. Throughout the process, workers can operate the rotating operating bracket from the side away from the end cap while the telescopic support component supports the end cap, preventing safety issues. The cooperation between the telescopic support component and the end cap transfer component also reduces the labor intensity of handling the end cap. Attached Figure Description

[0033] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0035] like Figure 1 As shown, this embodiment discloses an end cap disassembly and assembly device, which includes a vehicle body 100, a telescopic support assembly 200, a wrench module 300, and an end cap transfer assembly 400.

[0036] like Figure 2 As shown, the vehicle body 100 is constructed from square steel welded into a frame structure. Two handrails are installed on the sides for easy manual pushing of the vehicle body 100. A tool base plate is installed on the top of the vehicle body for placing the controller 500 and fixing the end cap transfer assembly 400. Four casters 110 are provided at the lower end of the vehicle body 100. Preferably, the casters 110 are swivel casters, distributed at the four corners of the vehicle body 100. In some preferred embodiments, a single swivel caster includes a connected hub and rollers. The hub has a diameter of 300mm and provides support. Multiple rollers are mounted perpendicular to the main axle of the swivel caster and arranged around the rim of the hub. Each roller can rotate freely. By combining multiple swivel casters, the vehicle body's speed and direction can be controlled, achieving: forward and backward movement (all swivel casters rotate in the same direction), lateral movement (left and right swivel casters rotate in opposite directions), and rotation in place (diagonal swivel casters rotate in opposite directions).

[0037] like Figure 2As shown, the telescopic support assembly 200 includes a first telescopic member 210 and an end cap pad 220. The first telescopic member 210 is fixedly disposed at the front end of the vehicle body 100, and its telescopic direction is configured in the height direction. In this embodiment, the first telescopic member 210 is preferably configured as an electric cylinder. The end cap pad 220 is fixedly connected to the telescopic end of the first telescopic member 210. Driven by the first telescopic member 210, the end cap pad 220 can move relative to the vehicle body 100 in the height direction to achieve the telescopic support function. In this embodiment, preferably, the end cap pad 220 is provided with a downwardly recessed support groove 220a. The support groove 220a is arc-shaped, and its inner arc surface can fit and contact the outer circumferential surface of the end cap to be disassembled. The support groove 220a provides stable support and limits the end cap, preventing the end cap from shifting.

[0038] like Figure 3 As shown, the wrench module 300 and the telescopic support assembly 200 are arranged at intervals in the horizontal direction. The wrench module 300 is used to remove the end cover from the locomotive and to put the end cover back onto the locomotive.

[0039] like Figure 3 As shown, the wrench module 300 includes a support plate 310, a mounting plate 320, a tightening mechanism 330, and a rotary operating support 340, as detailed below:

[0040] like Figure 3 As shown, the bracket plate 310 is hollow and circular. The bracket plate 310 is slidably mounted on the vehicle body 100. The bracket plate 310 can slide horizontally toward or away from the telescopic support assembly 200.

[0041] In this embodiment, the bracket plate 310 is preferably slidably disposed on the vehicle body 100 in the manner of a groove and protrusion matching structure in the prior art, or in the manner of the structure described in this embodiment.

[0042] Please refer to it again. Figure 2 The support plate 310 is slidably mounted on the vehicle body 100 via the guide assembly 120. The guide assembly 120 includes a guide rail 121, a guide slider 122, and a sliding plate 123. The guide rail 121 is located on one side of the vehicle body 100, and its length direction is configured to be horizontal. The guide slider 122 is connected to the guide rail 121 via guide rollers, which allows the guide slider 122 to move within the guide rail 121 via the guide rollers. One end of the sliding plate 123 is connected to the guide slider 122, and the support plate 310 is mounted on the sliding plate 123.

[0043] Please refer to it again. Figure 2In this embodiment, there are two guide rails 121 and two guide sliders 122, and they correspond one to one. The two ends of the sliding plate 123 are connected to the two guide sliders 122 respectively. In this embodiment, the sliding plate 123 can move in the horizontal direction through the cooperation of the guide sliders 122 and the guide rails 121. As a result, the support plate 310 provided on the sliding plate 123 can also move in the horizontal direction.

[0044] like Figure 3 As shown, the support plate 310 can be directly mounted on the sliding plate 123 or indirectly mounted on the sliding plate 123. In this embodiment, the support plate 310 is preferably indirectly mounted on the sliding plate 123 through the pitch fine-tuning component 350. The pitch fine-tuning component 350 enables the support plate 310 to pitch in the height direction so that the tightening machine 330 can be accurately aligned and connected with the connector on the end cap.

[0045] like Figure 3 As shown, the pitch fine-tuning assembly 350 includes a first support rod 351, a second support rod 352, and a joint bearing 353. The lower end of the first support rod 351 is mounted on the sliding plate 123, and the first support rod 351 is vertically upward. The upper end of the first support rod 351 is provided with the joint bearing 353. The axis of the second support rod 352 is parallel to the horizontal direction. One end of the second support rod 352 is connected to the joint bearing 353, and the other end of the second support rod 352 is connected to the support plate 310. In this embodiment, by setting the joint bearing 353, the support plate 310 can be pitch fine-tuned. Preferably, in this embodiment, there are two pitch fine-tuning assemblies 350, and the two pitch fine-tuning assemblies 350 are spaced apart on the sliding plate 123.

[0046] like Figure 3 As shown, the first support rod 351 can be directly connected to the sliding plate 123 or indirectly connected to it. In this embodiment, the first support rod 351 and the sliding plate 123 are preferably indirectly connected through a second telescopic member (not shown). The second telescopic member is configured as an electric cylinder and is fixedly mounted on the sliding plate 123. The telescopic direction of the second telescopic member is configured as the height direction. The telescopic end of the second telescopic member is coaxially fixedly connected to the lower end of the first support rod 351. The second telescopic member can drive the first support rod 351, the bracket plate 310, and the tightening machine 330 indirectly mounted on the bracket plate 310 to adjust their positions in the height direction, which is suitable for wheelset assembly and disassembly operations at different height positions.

[0047] like Figure 3As shown, the mounting plate 320 is circular in shape and is coaxially arranged with the support plate 310. The mounting plate 320 is rotatably connected to the support plate 310, enabling the mounting plate 320 to rotate coaxially with respect to the support plate 310. Preferably, in this embodiment, the rotatable connection between the mounting plate 320 and the support plate 310 can be as follows: a plurality of limiting rollers 311 are provided on one side of the support plate 310, and the multiple limiting rollers 311 are equally spaced along the circumference of the support plate 310, with the axial direction of the limiting rollers 311 parallel to the axial direction of the support plate 310; the mounting plate 320 is positioned between the multiple limiting rollers 311, restricting the mounting plate 320 and the support plate 310 to be in a coaxial state, and the limiting rollers 311 can roll in contact with the outer circumferential surface of the mounting plate 320, thereby enabling the mounting plate 320 to rotate relative to the support plate 310.

[0048] like Figure 4 As shown, a limiting groove 311a is provided on the outer circumference of the limiting roller 311. The limiting groove 311a surrounds the limiting roller 311 circumferentially. The edge of the mounting plate 320 is disposed within the limiting groove 311a, and the outer circumferential surface of the mounting plate 320 can roll in contact with the inner circumferential surface of the limiting groove 311a. In this embodiment, the position of the mounting plate 320 is limited by the limiting roller 311, which has a simple structure and is easy to assemble. Furthermore, the limiting groove 311a can not only enable the mounting plate 320 to rotate coaxially with respect to the support plate 310, but also limit the mounting plate 320 from moving away from or away from the support plate 310 along its axial direction.

[0049] like Figure 5 As shown, the mounting plate 320 has multiple mounting holes 320a, which are arranged radially at intervals along the mounting plate 320. This embodiment illustrates two mounting holes 320a on the mounting plate 320, used for mounting a tightening machine 330. The tightening machine 330 is based on existing servo tightening machines, specifically driven by a servo motor and reducer, and achieves precise tightening control through torque and angle sensors. Each tightening machine 330 is equipped with a dedicated control unit to set the tightening torque and perform torque control, angle control, and torque-angle composite control. The tightening machine 330 passes through one mounting hole 320a and connects to the mounting plate 320. The tightening machine 330 is used to remove or screw the connectors on the end cap onto the end cap. In this embodiment, the connectors refer to the bolts used to connect the end cap.

[0050] like Figure 5 As shown, in this embodiment, there are at least two tightening machines 330, and two mounting holes 320a are also provided. Figure 5In the middle, there is also a center hole (not shown) between the two mounting holes 320a, which facilitates the installation of other equipment. In some preferred embodiments, there are two tightening machines 330, while there can be multiple mounting holes 320a. The tightening machine 330 can be arbitrarily installed in any mounting hole 320a, which facilitates the assembly and disassembly of connectors with different positions and spacings.

[0051] like Figure 5 As shown, the rotary operating bracket 340 is connected to one side of the mounting plate 320, specifically to the side of the mounting plate 320 opposite to the telescopic support assembly 200, that is, the side opposite to the end cover. Operators can rotate the rotary operating bracket 340, thereby causing the mounting plate 320 to rotate relative to the bracket plate 310, thus adjusting the angle of the tightening machine 330.

[0052] like Figure 6 As shown, the end cap transfer assembly 400 is disposed on the vehicle body 100 and is used to transfer the end cap to a predetermined position, for example, transferring the end cap from the placement area to the end cap pad 220 of the telescopic support assembly 200, or transferring the end cap on the end cap pad 220 to the placement area. The end cap transfer assembly 400 can be the structure described in this embodiment, or it can be a gripping robot in the prior art.

[0053] like Figure 6 As shown, the end cap transfer assembly 400 includes a mounting base 410, a boom unit 420, and a clamping unit 430, as detailed below:

[0054] like Figure 7 As shown, the mounting base 410 is fixedly installed on the top of the vehicle body 100. There are two boom units 420, and the two boom units 420 have the same structure. The clamp unit 430 is used to clamp and release the end cover.

[0055] like Figure 7 As shown, the boom unit 420 includes a boom 421, a first joint head 422, a second joint head 423, and an electric cylinder 424. The first joint head 422 and the second joint head 423 are respectively hinged to both ends of the boom 421 along its length. The two ends of the electric cylinder 424 are respectively hinged to the first joint head 422 and the second joint head 423. The extension and retraction direction of the electric cylinder 424 is consistent with the length direction of the boom 421. Compared with traditional pneumatic or hydraulic cylinders, the electric cylinder 424 has the advantages of compact structure, precise positioning, energy saving and environmental protection, and intelligence.

[0056] like Figure 7As shown, the first joint head 422 of the first boom unit 420a is hinged to the mounting base 410, and the first joint head 422 of the first boom unit 420a can rotate horizontally relative to the mounting base 410. The second joint head 423 of the first boom unit 420a is hinged to one end of the transition plate 425, and the other end of the transition plate 425 is hinged to the first joint head 422 of the second boom unit 420b. The second joint head 423 of the second boom unit 420b is connected to the clamp unit 430.

[0057] The boom unit 420 of this embodiment can achieve multi-degree-of-freedom movement through multiple articulated joints, enabling precise positioning when gripping the end cap. In some preferred embodiments, bushings can be installed inside the articulated joints to effectively reduce friction between parts through lubrication.

[0058] like Figure 8 and Figure 9 As shown, the clamping unit 430 includes a back plate 431, a movable plate 432, a lead screw 433, grippers 434, and a gripper motor 435. A rotating shaft 436 is provided on the back side of the back plate 431. The rotating shaft 436 is rotatably connected to the second joint head 423 of the second boom unit 420b, enabling horizontal rotation. The rotating shaft 436 is connected to the back plate 431 via a flange. Two movable plates 432 are slidably connected to the lower surface of the back plate 431. The lead screw 433 is rotatably mounted on the back plate 431, and both lead screws 433 are threadedly engaged with the two movable plates 432. When the lead screw 433 rotates, the two movable plates 432 can move closer or further apart. The grippers 434 are correspondingly arranged... The grippers are placed on the movable plates 432. When the two movable plates 432 are relatively close, the two grippers 434 clamp. Conversely, when the two movable plates 432 are relatively far apart, the two grippers 434 release. The gripper motor 435 is configured as a servo motor and is set on the back plate 431. The gripper motor 435 is connected to the lead screw 433 and drives the lead screw 433 to rotate. The lead screw 433 includes two lead screw pieces, which are threadedly engaged with the movable plates 432. The two lead screw pieces are coaxially connected by a coupling 437. The gripper motor 435 is connected to the end gear of one of the lead screw pieces by a synchronous belt.

[0059] In some preferred embodiments, a limit switch is installed on the back plate 431 for end cap position detection and control signal feedback. A force-sensing handle is mounted on the back plate 431, allowing for convenient and quick manual operation of the boom unit 420 for handling and positioning the end cap.

[0060] In some preferred embodiments, the gripper motor 435 supports a torque control mode to achieve the positioning and clamping of the end cap. By controlling the output torque of the gripper motor 435, the clamping force is indirectly controlled, which can adapt to the dimensional tolerance of the end cap and achieve constant force control without the need for a high-precision force sensor. When the gripper motor 435 is running in position or speed mode, it quickly approaches the workpiece and monitors the torque of the gripper motor 435 in real time. When the torque suddenly increases (contact force threshold), it switches to torque mode to maintain the set torque and ensure a constant clamping force.

[0061] like Figure 10 As shown, in this embodiment, the disassembly and assembly device also includes a controller 500, which is disposed on the top of the vehicle body 100. The controller 500 includes a main control interface 510, a main control system 520, a tightening machine control unit 530, and an end cap transfer component control unit 540. The main control interface 510 is communicatively connected to the main control system 520, and the main control system 520 is communicatively connected to the tightening machine control unit 530 and the end cap transfer component control unit 540, respectively.

[0062] The main control system 520 is configured with an existing PLC controller. The main control system 520 controls the operation of the tightening machine 330 and the end cap transfer assembly 400 through the tightening machine control unit 530 and the end cap transfer assembly control unit 540, respectively. The specific functions that can be realized include: bolt tightening, bolt loosening, tightening torque setting and detection storage (accuracy ±10%), etc.

[0063] The working principle of the disassembly and assembly device in this embodiment is as follows:

[0064] Disassembly process:

[0065] Move the vehicle body 100 to the working position, and the telescopic support assembly 200 extends upward to support the disassembled end cap;

[0066] The bracket plate 310 drives the tightening machine 330 to approach the end cover to be removed. The angle of the tightening machine 330 is adjusted by rotating the operating bracket 340 so that the tightening machine 330 is aligned with the connector on the end cover. Then the tightening machine 330 is connected to the connector and the connector is unscrewed.

[0067] The end cap falls onto the telescopic support assembly 200, which supports the end cap after the connector has been disassembled.

[0068] Then, the worker manually operates the clamping unit 430 of the end cap transfer assembly 400 to move to the vicinity of the end cap and clamp the end cap. The worker then operates the boom unit 420 to transfer the end cap to a predetermined position, such as to the placement area.

[0069] Installation process:

[0070] The end cap installation process is the reverse of the disassembly process; please refer to the disassembly process for details, which will not be repeated here.

[0071] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
