Technical Field

[0001] The utility model relates to the technical field of robot cable protection, and particularly relates to a cable protection device for a robot. Background Technique

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. A robot can perform tasks such as operations or movements through programming and automatic control. Cable lines play an important role in power transmission. To ensure the reliability and stability of power supply, it is necessary to protect them. Protecting cable lines can ensure the safe operation of the lines. The cable protection device of a robot refers to a device that can avoid power damage caused by external interference or internal faults, thereby preventing the normal operation of the robot's power system.

[0003] After retrieval, a cable protection device for a pipeline robot in a Chinese utility model patent with the patent publication number CN212203601U includes a support frame arranged on one side of the wire outlet end of a cable car and a pulley frame installed on the support frame for the cable to pass through. An elevating mechanism for driving the pulley frame to lift is arranged on the support frame. The elevating mechanism includes a wire reel and a driving component for driving the wire reel to rotate. A rope is wound around the wire reel, and one end of the rope is connected to the pulley frame. The utility model has the advantage of reducing the wear on the cable when the pipeline robot travels in the pipeline. Although this device can reduce the wear on the cable when the pipeline robot travels in the pipeline, the cable is easily torn when being stretched, resulting in the exposure of the internal wires and thus the inability of the power system to operate normally. Therefore, a cable protection device for a robot is proposed, which can avoid the cable from being torn when the cable is forced to stretch, and is beneficial to maintaining the normal operation of the robot's power system.

[0005] To achieve the above-mentioned purpose of being able to avoid the cable from being torn when the cable is forced to stretch and being beneficial to maintaining the normal operation of the robot's power system, the utility model provides the following technical solution: A cable protection device for a robot includes a robot body, a robotic arm is fixedly installed on the top of the robot body, and a protection mechanism is arranged inside the robotic arm;

[0006] The protection mechanism includes a cable body, a protective shell, a fixing sleeve, a fixing column, a rubber roller, a moving hole, a nylon rope and a nylon ring. The cable body is fixedly installed inside the robotic arm. Two protective shells are fixedly installed outside the cable body. Two fixing sleeves are fixedly installed inside each of the two protective shells. Fixing columns are fixedly installed inside each of the four fixing sleeves. Rubber rollers are arranged outside each of the four fixing columns. Moving holes are formed outside each of the two protective shells. Two nylon ropes are fixedly installed on the opposite surfaces of the two protective shells. Nylon rings are fixedly installed outside the two nylon ropes.

[0007] Furthermore, an installation block is fixedly installed inside the protective shell, and an arc surface adapted to the cable body is formed inside the installation block.

[0008] Furthermore, limiting holes adapted to the cable body are formed inside each of the four fixing sleeves.

[0009] Furthermore, wear-resistant patterns are formed outside the cable body, and the four rubber rollers are all adapted to the wear-resistant patterns.

[0010] Furthermore, protective ropes are fixedly installed outside each of the two protective shells, and the two protective ropes are symmetrically arranged about the cable body as the center.

[0011] Furthermore, the number of the protection mechanisms is several, and the several protection mechanisms are evenly distributed outside the cable body.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] In the cable protection device for a robot, by arranging the protection mechanism, when the cable is stretched, the two protective shells fixedly connected to the cable body are forced to be pulled in two directions, left and right. The nylon rope and the nylon ring between the two protective shells are stretched to slow down the pulling force. The cable body wound inside the fixing sleeve inside the two protective shells is pulled, and the originally loose cable body is straightened by the rubber rollers, so as to avoid the cable body from being torn at the first time when being stretched, so that the cable body has a certain ductility. This protection mechanism can avoid the cable from being torn when the cable is forced to be stretched, which is beneficial to maintaining the normal operation of the power system of the robot.

The cable body 301 is fixedly installed inside the robotic arm 2, two protective shells 302 are fixedly installed on the outside of the cable body 301, two fixing sleeves 303 are fixedly installed inside each of the two protective shells 302, fixing columns 304 are fixedly installed inside each of the four fixing sleeves 303, rubber rollers 305 are arranged on the outside of each of the four fixing columns 304, moving holes 306 are opened on the outside of each of the two protective shells 302, two nylon ropes 307 are fixedly installed on the opposite surfaces of the two protective shells 302, and a nylon ring 308 is fixedly installed on the outside of the two nylon ropes 307.

[0022] In the case implementation, wear-resistant patterns are provided on the outside of the cable body 301, and the four rubber rollers 305 are all adapted to the wear-resistant patterns. By providing the wear-resistant patterns, the cable body 301 can rely on the cooperation of the rubber rollers 305 and the wear-resistant patterns when being stretched, so that the cable body 301 can slide smoothly.

[0023] In the case implementation, limiting holes adapted to the cable body 301 are opened inside each of the four fixing sleeves 303. By providing the limiting holes, the cable body 301 in the normal state can be in a loose state in the fixing sleeve 303.

[0024] In the case implementation, protective ropes are fixedly installed on the outsides of both protective shells 302.

[0025] During implementation, the following steps are taken for operation:

[0026] 1) First, when the cable is stretched, the two protective shells 302 fixedly connected to the cable body 301 are forced to be pulled in the left and right directions;

[0027] 2) Then, the nylon rope 307 and the nylon ring 308 between the two protective shells 302 are stretched to slow down the pulling force, and the cable body 301 wound inside the fixing sleeve 303 inside the two protective shells 302 is pulled;

[0028] 3) Then, the originally loose cable body 301 is straightened by the rubber roller 305;

[0029] 4) Finally, the cable body 301 is prevented from being torn at the first moment of being stretched, so that the cable body 301 has a certain degree of ductility.

[0030] In summary, for the cable protection device for a robot, by setting the protection mechanism 3, when the cable is stretched, the two protective shells 302 fixedly connected to the cable body 301 are forced to be pulled in the left and right directions. The nylon rope 307 and the nylon ring 308 between the two protective shells 302 are stretched to slow down the pulling force, and the cable body 301 wound inside the fixing sleeve 303 inside the two protective shells 302 is pulled. The originally loose cable body 301 is straightened by the rubber roller 305, thereby preventing the cable body 301 from being torn at the first moment of being stretched, so that the cable body 301 has a certain degree of ductility. The protection mechanism 3 can prevent the cable from being torn when the cable is forced to stretch, which is beneficial to maintaining the normal operation of the robot's power system.
