Description

Technical Field

[0001] The utility model relates to the field of robots, and more particularly to a climbing structure of a ladder-climbing robot. Background Art

[0002] A robot is an intelligent machine capable of semi- or fully autonomous operation. It can be programmed and automatically controlled to perform tasks such as work or movement. The earliest known robot in history was a wooden puppet crafted by craftsmen in the image of Liu Yan, commissioned by Emperor Yang of Sui. Equipped with mechanical mechanisms, it possessed the ability to sit, stand, bow, and crouch. Possessing fundamental capabilities such as perception, decision-making, and execution, robots can assist or even replace humans in completing dangerous, arduous, and complex tasks, improving work efficiency and quality, serving human life, and expanding or extending the scope of human activities and capabilities.

[0003] However, most robots currently on the market do not have the ability to climb stairs, which means that when they encounter stairs or obstacles similar to stairs, they often need to take a detour, which prolongs the robot's travel time and reduces its work efficiency. This is inconvenient and has certain limitations when used.

[0004] Therefore, in order to solve the above problems, a climbing structure of a ladder-climbing robot is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0007] 2. Technical solution

[0008] In order to solve the above problems, the present invention adopts the following technical solutions.

[0009] A climbing structure of a ladder robot includes a robot body, a No. 1 crawler track is installed on the outside of the robot body, a support rod is fixedly connected to one side of the robot body, the outside of the support rod is transmission-connected to the No. 1 crawler track, the inside of the support rod is rotatably connected to a mounting rod, a groove is provided in the middle of the support rod, a gear is provided in the middle of the mounting rod, a No. 2 crawler track is installed on both sides of the mounting rod, an electric cylinder is fixedly connected to the inside of the robot body, a bent rod is fixedly connected to the output end of the electric cylinder, a rack is fixedly connected to the bottom of the bent rod, and the rack is meshed with the gear.

[0010] Furthermore, the gear is located inside the slot body, and the outer diameter of the gear is smaller than the inner diameter of the slot body.

[0011] Furthermore, a motor is fixedly connected to the outside of the No. 2 crawler track, and the output end of the motor is transmission-connected to the No. 2 crawler track.

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Example:

[0028] See also Figure 1-4A ladder-climbing robot climbing structure includes a robot body 1, a No. 1 crawler 15 is installed on the outside of the robot body 1, a support rod 16 is fixedly connected to one side of the robot body 1, the outside of the support rod 16 is transmission-connected to the No. 1 crawler 15, the inside of the support rod 16 is rotatably connected to a mounting rod 18, a groove 17 is provided in the middle of the support rod 16, a gear 19 is provided in the middle of the mounting rod 18, and a No. 2 crawler 2 is installed on both sides of the mounting rod 18, an electric cylinder 22 is fixedly connected to the inside of the robot body 1, a bent rod 23 is fixedly connected to the output end of the electric cylinder 22, and a rack 24 is fixedly connected to the bottom of the bent rod 23. The rack 24 is meshed with the gear 19. In this solution, when the staff starts the device to climb the stairs, the electric cylinder 22 can be started to extend the output end of the electric cylinder 22. When the output end of the electric cylinder 22 is extended, the bent rod 23 will drive the rack 24 to move above the gear 19. Because the gear 19 and the rack 24 are meshed, when the rack 24 moves above the gear 19, it will drive the gear 19, that is, the mounting rod 18, to rotate. During this process, the No. 2 crawler 2 will rotate at a certain angle, and then one side of the No. 2 crawler 2 will contact the step surface of the stairs. Through the contact between the No. 2 crawler 2 and the stairs, the device can climb the stairs.

[0029] See also Figure 1-4 The gear 19 is located inside the groove body 17, and the outer diameter of the gear 19 is smaller than the inner diameter of the groove body 17. In this solution, since the outer diameter of the gear 19 is smaller than the inner diameter of the groove body 17, the gear 19 can rotate inside the support rod 16.

[0030] See also Figure 1-4 The outside of the No. 2 crawler 2 is fixedly connected with a motor 21, and the output end of the motor 21 is transmission-connected to the No. 2 crawler 2. In this solution, the motor 21 provides power for the rotation of the No. 2 crawler 2.

[0031] See also Figure 1-4 The robot body 1 is internally rotatably connected to a connecting rod No. 11 and a connecting rod No. 2 12. The middle part of the connecting rod No. 11 is rotatably connected to the middle part of the connecting rod No. 2 12. In this solution, the connecting rod No. 11 and the connecting rod No. 2 12 play a shock-absorbing and protective role for the device.

[0032] See also Figure 1-4 A spring 13 is provided between the No. 1 connecting rod 11 and the No. 2 connecting rod 12, and the two ends of the spring 13 are rotatably connected to the upper part of the No. 1 connecting rod 11 and the No. 2 connecting rod 12 respectively. In this solution, when the No. 1 track 15 rolls over the protrusion, the No. 1 connecting rod 11 and the No. 2 connecting rod 12 will both rotate. During this process, the spring 13 will be squeezed by the No. 1 connecting rod 11 and the No. 2 connecting rod 12 and elastically deformed, thereby cushioning the impact caused by the No. 1 track 15 rolling over the protrusion.

[0033] See also Figure 1-4 The end of the No. 1 connecting rod 11 is rotatably connected to the runner 14, and the runner 14 is transmission-connected to the No. 1 crawler track 15. In this solution, the runner 14 supports the No. 1 crawler track 15.

[0034] Working principle: When the staff starts this device to climb stairs, the electric cylinder 22 can be started to extend the output end of the electric cylinder 22. When the output end of the electric cylinder 22 is extended, the bent rod 23 will drive the rack 24 to move above the gear 19. Because the gear 19 and the rack 24 are engaged, when the rack 24 moves above the gear 19, it will drive the gear 19, that is, the mounting rod 18, to rotate. During this process, the No. 2 crawler 2 will rotate at a certain angle, and then one side of the No. 2 crawler 2 will contact the step surface of the stairs. Through the contact between the No. 2 crawler 2 and the stairs, this device can climb the stairs.

[0035] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
