[0031] Referring to Figures 1 to 3 , an embodiment provided by the present invention: a fixed limit device for mechanical walking, including two receiving shells 1. A driving component for providing power for the device is fixedly connected to the far side of each of the two receiving shells 1. Thus, the receiving shell 1 can provide support for the driving component. A circular gear 4 is fixedly connected to the near side of each of the two driving components. Further, the driving component can drive the circular gear 4 to rotate. The driving component includes two motors 1 2. The bottoms of the two motors 1 2 are respectively fixedly connected to the bottoms of the far sides of the two receiving shells 1. Then, the receiving shell 1 can provide support for the motor 1 2. The output ends of the two motors 1 2 are fixedly connected to output shafts 1 3. Thus, starting the motor 1 2 can cause the motor 1 2 to drive the output shaft 1 3 to rotate. The middle of the circular gear 4 is fixedly connected to the outside of the output shaft 1 3. Further, when the output shaft 1 3 rotates, it will drive the circular gear 4 to rotate. A limiting rod 5 is fixedly connected to the inside of the receiving shell 1. Then, the receiving shell 1 can provide support for the limiting rod 5. A rack plate 6 is slidably connected to the outside of the limiting rod 5. Thus, through the setting of the limiting rod 5, the movement of the rack plate 6 can be made more stable. The circular gear 4 and the rack plate 6 are meshed. Further, when the circular gear 4 rotates, it will drive the rack plate 6 to slide on the outside of the limiting rod 5. The outside of the rack plate 6 is slidably connected to the inside of the receiving shell 1. Then, the receiving shell 1 can make the movement of the rack plate 6 more stable. Connecting rods 7 are fixedly connected to the front, rear, left, and right sides of the rack plate 6. Thus, when the rack plate 6 moves, it will drive the connecting rods 7 to move.

[0032] A spring 8 is sleeved on the outside of the connecting rod 7. A force-bearing plate 9 is slidably connected to the outside of the connecting rod 7. Thus, through the setting of the connecting rod 7, the movement of the force-bearing plate 9 can be made more stable. One end of the spring 8 is fixedly connected to the outside of the force-bearing plate 9, and the other end of the spring 8 is fixedly connected to the outside of the rack plate 6. Thus, when the force-bearing plate 9 is stressed, it will compress the spring 8. The outside of the force-bearing plate 9 is slidably connected to the inside of the receiving shell 1. Further, the receiving shell 1 can make the movement of the force-bearing plate 9 more stable. A sliding hole 10 is opened at the bottom of the receiving shell 1. A sliding block 1 11 is fixedly connected to the bottom of the rack plate 6. Then, when the rack plate 6 moves, it will drive the sliding block 1 11 to move. The outside of the sliding block 1 11 is slidably connected to the inside of the sliding hole 10. Thus, the setting of the sliding hole 10 can make the movement of the sliding block 1 11 more stable;

[0033] Referring to Figure 1 andFigure 4 , a height - adjusting component for adjusting the height is fixedly connected to the bottom of the first sliding block 11. Thus, when the first sliding block 11 moves, it will drive the height - adjusting component to move. The bottom of the height - adjusting component is fixedly connected to a mounting plate 13. Furthermore, starting the height - adjusting component can enable the height - adjusting component to drive the mounting plate 13 to adjust the height. The height - adjusting component includes a hydraulic rod 12. The top of the hydraulic rod 12 is fixedly connected to the bottom of the first sliding block 11. Then, when the first sliding block 11 moves, it will drive the hydraulic rod 12 to move. The top of the mounting plate 13 is fixedly connected to the output end of the hydraulic rod 12. Thus, starting the hydraulic rod 12 can enable the output end of the hydraulic rod 12 to drive the mounting plate 13 to adjust the height. One side of the mounting plate 13 is fixedly connected to a second motor 14. Furthermore, the mounting plate 13 can provide support for the second motor 14. The output end of the second motor 14 is fixedly connected to an output shaft 15. Then, starting the second motor 14 can enable the second motor 14 to drive the output shaft 15 to rotate.

[0034] An external part of the output shaft 15 is fixedly connected to a first half - gear 16. Thus, when the output shaft 15 rotates, it will drive the first half - gear 16 to rotate. The left side of the mounting plate 13 is rotatably connected to a rotating shaft 17. Furthermore, the mounting plate 13 can provide support for the rotating shaft 17. An external part of the rotating shaft 17 is fixedly connected to a second half - gear 18. The first half - gear 16 and the second half - gear 18 are meshed. Then, when the first half - gear 16 rotates, it will drive the second half - gear 18 to rotate. Clamping plates 19 are fixedly connected to the exteriors of both the first half - gear 16 and the second half - gear 18. Thus, when both the first half - gear 16 and the second half - gear 18 rotate, they will both drive a clamping plate 19 to move. Furthermore, when the clamping plate 19 moves, it will clamp and fix the material. Support columns 20 are fixedly connected to the left and right sides of the bottom of the accommodating shell 1. Then, the support columns 20 can provide support for the accommodating shell 1. The bottom of the support column 20 is fixedly connected to a moving component for moving the device. Thus, starting the moving component can enable the starting component to drive the support column 20 to move. The moving component includes an electric guide rail 22. A second sliding block 21 is slidably connected to the exterior of the electric guide rail 22. Furthermore, starting the electric guide rail 22 can enable the electric guide rail 22 to drive the second sliding block 21 to move. The bottom of the support column 20 is fixedly connected to the top of the second sliding block 21. Then, when the second sliding block 21 moves, it will drive the support column 20 to move.

[0035] Working principle: When it is necessary to use the device for material clamping or transportation operations, first start the first motor 2. The first motor 2 drives the circular gear 4 to rotate through the output shaft 3. The circular gear 4 meshes with the rack plate 6. The rack plate 6 slides along a specified direction under the guidance of the limiting rod 5. The movement of the rack plate 6 drives the connecting rod 7 connected thereto to move synchronously, laying a foundation for subsequent material clamping and transportation.

[0036] As the rack plate 6 slides, when it moves a certain distance, the rotation of the circular gear 4 will press the force-bearing plate 9. The force-bearing plate 9 is compressed under the action of the connecting rod 7 and the spring 8. After the spring 8 is compressed, it generates a reaction force, pushing the force-bearing plate 9 out of engagement with the circular gear 4. At this time, the rack plate 6 stops moving, realizing the stroke limit of the device, thereby preventing the device from colliding with physical obstacles due to continuous movement and avoiding equipment damage.

[0037] Next, according to the size of the goods to be clamped, the electric guide rail 22 is started. The electric guide rail 22 drives the support column 20 to slide through the slider two 21, and the mounting plate 13 on the support column 20 also moves accordingly, enabling the two clamping plates 19 of the device to approach or move away from each other according to the width of the goods, completing the width adjustment.

[0038] After the width of the clamping plate 19 is adjusted, the operator starts the hydraulic rod 12 according to the height requirement of the goods. The hydraulic rod 12 is connected to the slider one 11, and the slider one 11 moves along the vertical direction of the device through the sliding hole 10, enabling the hydraulic rod 12 to drive the mounting plate 13 to move up and down, thereby realizing the adjustment of the overall height of the clamping device.

[0039] After the width and height are adjusted to the appropriate positions, the motor two 14 is started. The motor two 14 drives the half gear one 16 to rotate through the output shaft two 15. The half gear one 16 meshes with the half gear two 18, and the half gear two 18 also rotates synchronously. The half gear one 16 and the half gear two 18 are respectively connected to the two clamping plates 19. As the half gear one 16 and the half gear two 18 rotate, the two clamping plates 19 will move towards or away from each other. When the two clamping plates 19 move towards the middle, they will clamp and fix the goods in the middle position.

[0040] After the goods are clamped and fixed, the electric guide rail 22 is started again. At this time, the electric guide rail 22 drives the entire device to move along the established trajectory through the slider two 21, and the clamping plate 19 and the goods move together with the device for smooth transportation.

[0041] After the device moves the goods to the designated position, the operation of the electric guide rail 22 is stopped. If necessary, the clamping plate 19 can be separated by operating the motor two 14 in reverse, so that the goods are released from the clamped state, completing the transportation and unloading operation of the materials.

[0042] During the entire moving process, if the device runs to the end of the stroke again, the circular gear 4 will press the force-bearing plate 9 again. After the spring 8 is compressed, the force-bearing plate 9 is disengaged from the circular gear 4, and the limit function is triggered again to ensure that the device will not collide due to continuous walking and ensure the operation safety.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
