[0029] Embodiment 2. On the basis of embodiment 1, this embodiment provides a limiting structure of a load-bearing sleeve. Specifically, the clamping mechanism includes a support arm 33 fixedly connected to the top of the mechanical arm 4 and a clamping arm 34 rotatably connected to the top of the mechanical arm 4. A clamping hydraulic rod 35 is installed between the clamping arm 34 and the mechanical arm 4. The end of the support arm 33 away from the mechanical arm 4 is fixedly connected to a support seat 36. The cross-section of the support seat 36 is arranged in an arc shape. The end of the clamping arm 34 away from the mechanical arm 4 is fixedly connected to a clamping top plate 37. The cross-section of the clamping top plate 37 is arranged in an arc shape. When in use, the load-bearing sleeve is placed inside the support seat 36, and the hydraulic rod 35 pushes the clamping arm 34 to swing, so that the clamping top plate 37 clamps the load-bearing sleeve. , both sides of the clamping top plate 37 are slidably connected with correction rods 38, the lower end of the correction rod 38 is rotatably connected with a control roller 39, and both ends of the clamping top plate 37 are rotatably connected with a V-shaped limit plate 40, the end of the correction rod 38 away from the control roller 39 is slidably connected to one end of the limit plate 40, and the end of the limit plate 40 close to the correction rod 38 is provided with a sliding groove, and the end of the correction rod 38 close to the limit plate 40 is fixedly connected with a sliding shaft slidably connected to the sliding groove, and a reset spring 41 is installed between the correction rod 38 and the clamping top plate 37. In the initial state, under the action of the reset spring 41, the correction rod 38 is pulled in the direction close to the support seat 36, and the correction rod 38 drives the end of the limit plate 40 close to the correction rod 38 to swing downward.

[0030] When in use, the load-bearing sleeve is placed inside the support seat 36, and the hydraulic rod 35 pushes the clamping arm 34 to swing, so that the clamping top plate 37 clamps the load-bearing sleeve. When the clamping top plate 37 clamps the load-bearing sleeve, the control roller 39 contacts the load-bearing sleeve and pushes it in the direction away from the load-bearing sleeve. The limiting plate 40 is driven to swing through the correction rod 38, so that the end of the limiting plate 40 away from the correction rod 38 swings downward until the end of the limiting plate 40 away from the correction rod 38 is perpendicular to the clamping top plate 37. When swinging, the load-bearing sleeve is pushed to slide to the position located in the center of the support seat 36 at the same time, so as to control the position of the load-bearing sleeve and ensure that the load-bearing sleeve will not slide when it is transported.

[0031] A plurality of sliding grooves 42 are provided on the sides where the clamping top plate 37 and the support seat 36 approach each other, and a guide plate 43 is slidably connected inside the sliding groove 42. A tension spring 44 is installed between the guide plate 43 and the sliding groove 42. In the initial state, the tension spring 44 controls the guide plate 43 to be located in the middle position of the sliding groove 42, and the load-bearing sleeve is placed on the guide plate 43. When the limit plate 40 pushes the load-bearing sleeve to slide inside the support seat 36, it simultaneously drives the guide plate 43 to slide, thereby reducing friction and protecting the load-bearing sleeve.

[0032] When implementing it specifically, The load-bearing sleeve is placed inside the support seat 36, and the hydraulic rod 35 pushes the clamping arm 34 to swing, so that the clamping top plate 37 clamps the load-bearing sleeve. When the clamping top plate 37 clamps the load-bearing sleeve, the control roller 39 contacts the load-bearing sleeve and pushes it in the direction away from the load-bearing sleeve. The limiting plate 40 is driven to swing through the correction rod 38, so that the end of the limiting plate 40 away from the correction rod 38 swings downward until the end of the limiting plate 40 away from the correction rod 38 is perpendicular to the clamping top plate 37. When swinging, the load-bearing sleeve is pushed to slide to the position located at the center of the support seat 36 at the same time, so as to control the position of the load-bearing sleeve and ensure that the load-bearing sleeve will not slide when it is transported.

[0033] When it is necessary to transfer the load-bearing sleeve, the driving motor drives the driving wheel 18 to rotate, driving the supporting base 3 to slide onto the control slider 16. The supporting base 3 slides in the direction close to the buffer plate 5 to transfer the load-bearing sleeve. After the support base 3 and the buffer plate 5 come into contact, the buffer spring 6 is compressed to make the buffer plate 5 slide in the direction away from the bottom plate 1. The buffer plate 5 drives the pushing plate 10 to slide synchronously. At the same time, the pushing plate 10 drives the sliding ring 24 to slide on the brake rod 7 by pushing the connecting rod 11. When the pushing connecting rod 11 drives the sliding ring 24 to slide upward, the straight surface of the sliding block 27 contacts the straight edge surface of the support block 23, and the sliding block 27 drives the support block 23 to slide upward synchronously. The support block 23 drives the brake rod 7 to slide upward synchronously until the brake rod 7 slides upward to the limit position, and the brake block 8 is stuck in the brake groove 9 to realize the fixed brake operation. At this time, the support base 3 slides to a fixed position to clamp or place the load-bearing sleeve.

[0034] After the brake lever 7 slides upward to the limit position, the unlocking control plate 31 unlocks the matching plate 30 and slides in a direction away from the support block 23, so that the matching sliding block 27 and the support block 23 are out of contact.

[0035] When transportation is required, the driving motor rotates in the opposite direction to drive the driving wheel 18 to rotate in the opposite direction. At this time, under the action of friction, the driving wheel 18 first drives the control slider 16 to slide in the direction away from the supporting base 3. At this time, the control slider 16 pushes the unlocking push plate 20 to slide in the direction away from the brake rod 7 through the control push plate 19. The unlocking push plate 20 drives the control rod 12 to slide away from the brake rod 7. At this time, the self-locking block 14 and the self-locking slot 13 are separated. Under the action of the unlocking spring 29, the brake rod 7 is pushed in the direction away from the brake slot 9, so that the brake block 8 and the brake slot 9 are separated.

[0036] When the buffer plate 5 is reset under the action of the buffer spring 6, the connecting rod 11 is pushed to drive the sliding ring 24 to slide downward, and the inclined surface of the matching sliding block 27 contacts the inclined surface of the support block 23. At this time, the inclined surface of the support block 23 pushes the matching sliding block 27 to slide in the direction away from the brake rod 7. When the matching sliding block 27 slides over the position of the support block 23, under the action of the clamping spring 28, the matching sliding block 27 is pushed in the direction close to the support block 23, and the straight edge of the matching sliding block 27 is in contact with the straight edge of the support block 23. Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
