Description

Technical Field

[0001] This utility model relates to the field of pin-pulling robot technology, specifically a train coupler pin-pulling robot. Background Technology

[0002] The train coupler is a crucial component used to connect locomotives and carriages, or cars and cars together. It not only transmits traction and impact forces but also maintains a certain distance between carriages to facilitate passage through curves. The train coupler mainly consists of three parts: the coupler head, the coupler body, and the coupler tail. The front end of the coupler head is thick and contains components such as the coupler tongue, coupler tongue pin, locking pin, coupler tongue pusher, and coupler lock iron. These components work together to achieve the coupling and locking functions of the coupler. The coupler body connects the coupler head and the coupler tail, providing fixation and support. The coupler tail has vertical flat locking holes that can connect to the coupler tail frame, ensuring the stability of the coupler.

[0003] However, existing train coupler pin removal robots cannot adjust the distance between the two grippers according to the distance between the two pins during actual use, resulting in limited flexibility during use. To address this problem, a train coupler pin removal robot is provided. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a train coupler pin removal robot, including a base 1, a mechanical arm 2 at the top of the base 1, a frame 3 on the mechanical arm 2, an adjustment component inside the frame 3, and two sliding components on the adjustment component. Each sliding component has two grippers 4, and the sides of the two grippers 4 that are close to each other are adapted to fit the outer wall of the coupler pin removal device. Wheels 5 are provided at the four corners of the bottom of the base 1. By setting the sliding components, the two grippers 4 can slide simultaneously toward the middle of the slider 8, thereby clamping and fixing the pin. Then, the mechanical arm 2 slides the grippers 4 upward to remove the pin, thus realizing the pin removal operation of the device. By setting the adjustment component, the distance between the two sliding components can be adjusted, thereby matching the fixed grippers 4 on the two sliding components with the corresponding pin positions. This solves the problem that the existing train coupler pin removal robots cannot adjust the distance between the two grippers 4 according to the distance between the two pins in actual use, resulting in limited flexibility in use.

[0023] In this embodiment, the adjustment assembly includes a motor 6, a lead screw 7, sliders 8, and a limiting assembly. The motor 6 is located at the left end of the frame 3, and its output end extends into the inner cavity of the frame 3. One end of the lead screw 7 is rotatably connected to the right side of the inner cavity of the frame 3 via a bearing, and the other end of the lead screw 7 is fixedly connected to the output end of the motor 6. Two sliders 8 are respectively screwed onto the left and right sides of the outer wall of the lead screw 7. The limiting assembly is located on the rear side of the inner cavity of the frame 3 and is fixedly connected to the two sliders 8. The two sliders 8 are respectively connected to two adjustment assemblies. When the motor 6 is started, it drives the lead screw 7 to rotate, thereby generating a relative thread rotation force on the opposing threads on the left and right sides of the outer wall of the lead screw 7. This causes the two sliders 8 to slide relative to each other simultaneously under the limiting action of the limiting groove 9 and the limiting block 10, thereby adjusting the distance between the two sliding assemblies. This allows the grippers 4 fixed on the two sliding assemblies to match the corresponding pin positions, solving the problem that the existing train coupler pin-removing robot cannot adjust the distance between the two grippers 4 according to the distance between the two pins during actual use, resulting in limited flexibility during use.

[0024] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 7 are arranged opposite to each other, so that when the lead screw 7 rotates, the opposite threads on the left and right sides of its outer wall generate opposite thread rotation force, so that the two sliders 8 slide relative to each other simultaneously under the limiting action of the limiting groove 9 and the limiting block 10.

[0025] In this embodiment, the limiting component includes a limiting groove 9 and a limiting block 10. The limiting groove 9 is opened on the rear side of the inner cavity of the frame 3. Both limiting blocks 10 are slidably embedded in the inner cavity of the limiting groove 9 and are respectively fixedly connected to two sliders 8. Under the joint action of the limiting groove 9 and the limiting block 10, the slider 8 can be prevented from rotating with the lead screw 7 when the lead screw 7 rotates, thus improving the stability of the sliding component during use.

[0026] In this embodiment, the inner cavity of the limiting groove 9 and the outer wall of the limiting block 10 are adapted to each other and are both in the shape of a "T". This allows one end of the limiting block 10 to always remain embedded in the inner cavity of the limiting groove 9, thereby improving the stability of the limiting component during use.

[0027] In this embodiment, the sliding assembly includes a connecting assembly, a rack 13, a rotating column 15, a gear 16, a connecting rod 14, and a driving assembly. Both connecting assemblies are located at the front end of the slider 8. The two racks 13 are respectively located at the front end of the two connecting assemblies. The two connecting rods 14 are respectively located at the front end of the two racks 13 and are respectively fixedly connected to the two grippers 4. One end of the rotating column 15 is rotatably connected to the front end of the slider 8 through a bearing. The gear 16 is fixedly sleeved on the outer wall of the rotating column 15. The driving assembly is located at the front end of the slider 8 and is fixedly connected to one of the racks 13. The driving assembly drives the rack 13 to slide along a straight line under the limiting action of the connecting block 12 and the connecting groove 11. Since both racks 13 are meshed with the gear 16, when one rack 13 slides, the other rack 13 can slide relative to it at the same time, thereby causing the two grippers 4 to slide towards the middle of the front end of the slider 8 at the same time, so that the two grippers 4 clamp and fix the pin.

[0028] In this embodiment, both racks 13 mesh with the gear 16, so that when one rack 13 slides, the other rack 13 slides relative to it simultaneously under the action of the gear 16.

[0029] In this embodiment, the connecting component includes a connecting groove 11 and a connecting block 12. The connecting groove 11 is opened at the front end of the slider 8. The connecting block 12 is slidably embedded in the inner cavity of the connecting groove 11 and fixedly connected to the rack 13. Under the combined action of the connecting block 12 and the connecting groove 11, the rack 13 can always slide along a straight line.

[0030] In this embodiment, the inner cavity of the connecting groove 11 and the outer wall of the connecting block 12 are adapted to each other and are both dovetail-shaped, so that one end of the connecting block 12 is always embedded in the inner cavity of the connecting groove 11, preventing the connecting block 12 from disengaging from the inner cavity of the connecting groove 11 and causing the rack 13 to disengage from the gear 16.

[0031] In this embodiment, the driving component includes a cylinder 17, which is disposed at the front end of the slider 8. The output end of the cylinder 17 is fixedly connected to one of the racks 13 through a connecting plate. When the cylinder 17 is activated, it drives one of the racks 13 to slide.

[0032] 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 preferred examples and are not intended to limit the utility model.
