Description
Technical Field
[0001] This utility model relates to the field of bogie disassembly technology, and specifically provides a key disassembly device. Background Technology
[0002] The bogie key is a small wedge-shaped component near the bearing on the bogie, installed in the side frame guide frame. When the bogie is under tension, the key connects the side frame to the wheelset, preventing the wheelset from detaching. When wheelset maintenance is required, the key bolts need to be loosened and then retracted. For a long time, railway vehicle maintenance plants have relied on manual labor for loosening key bolts. To reduce labor intensity, devices for automatically removing key bolts on railway freight cars have been developed. These devices typically include an electric wrench for loosening the key and a rotating plate for pushing it out. Since a bogie usually has a pair of symmetrical key bolts on both sides, mirror-image equipment is needed to remove the left and right key bolts on one side of the bogie, significantly increasing equipment costs. Therefore, a new type of key removal device is urgently needed to reduce costs. Utility Model Content
[0003] On the one hand, in order to solve the above problems, this utility model provides a new type of disassembly key device, which can adapt to the disassembly of key components in various directions and can directly adapt to key components of different specifications without manual adjustment.
[0004] The technical solution of this utility model is as follows:
[0005] A key removal device includes a support arm, one end of which is connected to a robotic arm, and the other end of which is vertically provided with a hollow rotating shaft. A wrench mechanism is provided in the hollow rotating shaft, and a push plate is provided on the outer sleeve of the hollow rotating shaft. A horizontal push module is provided on the push plate, and a drive mechanism is also provided on the support arm. The drive mechanism is used to drive the push plate to rotate around the hollow rotating shaft.
[0006] In this scheme, the wrench mechanism is used to loosen the fixing bolts of the stop key. Since the horizontal push assembly that pushes the stop key back is set on the rotatable push plate, after the disassembly of one end is completed, the drive mechanism drives the push plate to rotate around the hollow shaft to the symmetrical position on the other side of the support arm, so that the disassembly of the other stop key on one side of the bogie can be achieved. For the disassembly of the stop key on one side of the bogie, only one device is needed, which greatly saves equipment costs.
[0007] Preferably, a gear ring is provided at one end of the push plate near the hollow rotating shaft, the gear ring is sleeved on the hollow rotating shaft, and the drive mechanism drives the rotation of the push mechanism through gear transmission.
[0008] Preferably, the drive mechanism includes a motor with a controller (the motor is connected to a power source), the motor is fixedly mounted on the upper surface of the support arm, the motor drives the drive shaft downward through the support arm via a reducer, and is connected to a horizontal gear, the horizontal gear meshing with the gear ring.
[0009] On the other hand, in order to adapt to different sizes and specifications of key stops and improve the adaptability of the rotating shaft, the horizontal pushing module is slidably disposed on the pushing plate along the length direction of the pushing plate. The horizontal pushing module includes an electric push rod electrically connected to the controller and a sliding block pushed by the electric push rod. The sliding block is disposed on the slide rail on the surface of the pushing plate.
[0010] In this design, the horizontal pushing module can move a sliding block horizontally, causing it to push the loosened key towards the center of the bogie from a distance, thus retracting the key. Furthermore, by simply adjusting the angle between the pushing plate and the support arm through the drive mechanism to ensure accurate positioning of the horizontal pushing module, it can push keys of various specifications, thereby retracting the loosened key.
[0011] Preferably, the sliding block is provided with a vertical sliding hole, a top block is slidably inserted into the sliding hole, and an elastic member is provided between the top block and the sliding block, the elastic member providing a force to the top block away from the sliding block.
[0012] In this design, before loosening the stop bolt, the wrench mechanism typically performs an upward movement to allow the stop bolt to smoothly enter the wrench mechanism. During this time, the top block is also pressed down by the hub or other structure, causing the elastic component to contract. After loosening, as the sliding block is pushed, the top block moves vertically away from the obstruction of the hub or other structure. The top block presses against the stop bolt and applies an upward force to the stop bolt, making it easier to push.
[0013] In order to ensure that the drive mechanism can accurately control the rotation of the push plate to the working position, a sensing mechanism is also included. The sensing mechanism includes sensing modules symmetrically arranged on both sides of the support arm and triggering modules symmetrically arranged on both sides of the push plate. When the push plate rotates to the working angle on both sides of the support arm, the triggering module triggers the sensing module and stops the drive mechanism from moving.
[0014] Preferably, the sensing module includes a photoelectric gate and a mounting plate. The photoelectric gate is mounted on both sides of the support arm via the mounting plate. The triggering module includes a probe, which is inclinedly disposed on the side wall of the push plate. By rotating the push plate, the probe can be inserted into the sensing end of the photoelectric gate.
[0015] Preferably, the mounting plate is hinged to the support arm, and the probe is hinged to the push plate. By adjusting the angle of the mounting plate and the angle of the probe, the working angle of the push plate can be adjusted.
[0016] The beneficial effects of this utility model are as follows: The wrench mechanism of this utility model is used to loosen the fixing bolts of the stop key. Since the horizontal push assembly that pushes the stop key back is set on the rotatable push plate, after the disassembly of one end is completed, the drive mechanism drives the push plate to rotate around the hollow shaft to the symmetrical position on the other side of the support arm, so that the disassembly of the other stop key on one side of the bogie can be realized. For the disassembly of the stop component of a single side of the bogie, only one device is needed to complete the disassembly, which greatly saves equipment costs. Attached Figure Description

Detailed Implementation
[0023] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.
[0024] Example 1:
[0025] A key removal device, such as Figure 1 and Figure 2As shown, a support arm 1 is attached, with one end connected to a robotic arm and the other end vertically mounted with a hollow rotating shaft 2. A wrench mechanism 3 is installed in the hollow rotating shaft 2, and a push plate 4 is mounted on the hollow rotating shaft 2. A horizontal push module 6 is mounted on the push plate 4. A drive mechanism 5 is also mounted on the support arm 1, which is used to drive the push plate 4 to rotate around the hollow rotating shaft 2.
[0026] The push plate 4 has a gear ring 41 near the hollow rotating shaft 2. The gear ring 41 is sleeved on the hollow rotating shaft 2. The drive mechanism 5 drives the rotation of the push mechanism through gear transmission. It can also be driven by a chain, rack, or other mechanism, but gear transmission is preferred. Specifically, the drive mechanism 5 includes a motor 51 with a controller. The motor 51 is externally powered and is fixedly mounted on the upper surface of the support arm 1. The motor 51 drives the drive shaft downward through the support arm 1 via a reducer 53 and is connected to a horizontal gear 52, which meshes with the gear ring 41. When the motor 51 operates, it drives the horizontal gear 52 to rotate, thereby rotating the push plate 4 to adjust the position of the horizontal push module 6.
[0027] In this embodiment, the wrench mechanism 3 is used to loosen the fixing bolts of the bogie key, and a baffle can be set to abut against the frame to counteract the torque generated when the wrench mechanism 3 loosens the bolts. Since the horizontal push assembly that pushes the bogie key back is set on the rotatable push plate 4, after the disassembly of one end is completed, the drive mechanism 5 drives the push plate 4 to rotate around the hollow shaft 2 to a symmetrical position on the other side of the support arm 1, thereby realizing the disassembly of the other bogie key on one side. For the disassembly of the bogie key on one side, only one device is needed, which greatly saves equipment costs.
[0028] Example 2:
[0029] Based on Example 1, in order to adapt to different sizes and specifications of key stops and improve the compatibility of the rotating shaft, such as... Figure 1 and Figure 3 As shown, the horizontal pushing module 6 is slidably disposed on the pushing plate 4 along the length direction of the pushing plate 4. The horizontal pushing module 6 includes an electric push rod 61 electrically connected to the controller and a sliding block 62 pushed by the electric push rod 61. The sliding block 62 is disposed on the slide rail 63 on the surface of the pushing plate 4.
[0030] Specifically, the horizontal pushing module 6 can push the loosened stop key from a distance by horizontally moving the sliding block 62, thereby retracting the stop key. Furthermore, by simply adjusting the angle between the pushing plate 4 and the support arm 1 through the drive mechanism 5 to ensure accurate pushing of the horizontal pushing module 6, it can push stop keys of various specifications, thus retracting the loosened stop key.
[0031] Furthermore, the sliding block 62 is provided with a vertical sliding hole, in which a top block 64 is slidably inserted. An elastic member is provided between the top block 64 and the sliding block 62, and the elastic member provides a force to the top block 64 away from the sliding block 62. Before the wrench mechanism 3 loosens the stop bolt, it generally has an upward movement so that the stop bolt can smoothly enter the wrench mechanism 3. At this time, the top block 64 can also be pressed down by the hub or other structures, causing the elastic member to contract. After the loosening is completed, during the pushing process of the sliding block 62, the top block 64 presses against the stop bolt and applies an upward force to the stop bolt, making it easier to push the stop bolt.
[0032] Example 3:
[0033] Based on the above embodiments, in order to ensure that the drive mechanism 5 can accurately control the rotation of the push plate 4 until it is in operation, such as... Figure 2 and Figure 3 As shown, it also includes a sensing mechanism 7, which can be an angle sensor, a distance sensor, etc., used to control the stop of the drive mechanism 5. Preferably, the sensing mechanism 7 includes sensing modules 71 symmetrically arranged on both sides of the support arm 1 and trigger modules 72 symmetrically arranged on both sides of the push plate 4. When the push plate 4 rotates to the working angle on both sides of the support arm 1, the trigger module 72 triggers the sensing module 71, causing the drive mechanism 5 to stop and fix the position of the push plate 4.
[0034] Specifically, the sensing module 71 includes a photoelectric gate 711 and a mounting plate 712. The photoelectric gate 711 is mounted on both sides of the support arm 1 via the mounting plate 712. The triggering module 72 includes a probe 721. The probe 721 is inclinedly disposed on the side wall of the push plate 4. By rotating the push plate 4, the probe 721 can be inserted into the sensing end of the photoelectric gate 711.
[0035] Furthermore, the mounting plate 712 is hinged to the support arm 1, and the probe 721 is hinged to the push plate 4. By adjusting the angles of the mounting plate 712 and the probe 721, the working angle of the push plate 4 can be adjusted. The hinged structure can be fixed by setting a large damping, or the angles of the mounting plate 712 and the probe 721 can be adjusted and fixed by a bolt locking structure or a positioning pin structure.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
