[0003] When inspecting the main cable, it is usually necessary to connect the inspection clamp to the main cable. However, some existing main cable inspection devices usually use a spring as the closing force of the inspection clamp. However, after long-term use, the spring is prone to fatigue deformation, which affects the closing of the inspection clamp. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a lightweight main cable detection and maintenance device.

[0005] The utility model adopts the following technical scheme to achieve: a lightweight main cable detection and maintenance device, including a base plate, the top of the base plate is fixedly connected to a fixing box, the bottom of the base plate is threadedly connected to a threaded rod, the top of the threaded rod passes through the bottom of the base plate and extends into the inside of the fixing box, the bottom of the threaded rod is fixedly connected to a rotating rod, the top of the threaded rod is rotatably connected to the installation box, the installation box is provided with a slide groove, the inside of the slide groove is slidably connected to a slide rod, both ends of the slide rod are fixedly connected to a limiting block, the inner wall of the fixing box is provided with a guide groove, the limit block is slidably connected to the inside of the guide groove, the inner wall of the fixing box is fixedly connected to the fixing rod, the outer wall of the fixing rod is rotatably connected to the detection clamp, and the bottom of the detection clamp is rotatably connected to the outer wall of the slide rod.

[0006] With the above technical solution, the threaded rod can be driven to rotate by rotating the rotating rod. The rotation of the threaded rod will change the length of the threaded rod inside the fixed box, thereby pushing the installation box to move.

[0007] As a further improvement of the above solution, two fixing boxes are provided, and the two fixing boxes are symmetrically arranged around the center of the base plate. The limit block is circular, the diameter of the limit block is larger than the width of the slide groove, and the width of the guide groove is the same as the diameter of the limit block.

[0008] As a further improvement of the above solution, the inner wall of the detection clamp is fixedly connected to a first sleeve, the inner wall of the first sleeve is fixedly connected to a first spring, the end of the first spring close to the center of the detection clamp is fixedly connected to a first limiting plate, and the first limiting plate is slidably connected to the inside of the first sleeve.

[0009] As a further improvement of the above scheme, the first connecting rod is fixedly connected to the side of the first limiting plate away from the first spring. The first connecting rod is sleeved with the first sleeve. The end of the first connecting rod away from the first limiting plate passes through the outer wall of the first sleeve and extends. The end of the first connecting rod away from the first limiting plate is fixedly connected to the guide wheel.

[0010] Through the above technical solution, the first limiting piece can be used to limit the first connecting rod, thereby preventing the first connecting rod from being separated from the sleeve, thereby causing the guide wheel to be separated.

[0011] As a further improvement of the above solution, the detector body is fixedly connected to the top of the base plate, the second sleeve is fixedly connected to the top of the base plate, the second spring is fixedly connected to the bottom wall inside the second sleeve, the second limit plate is fixedly connected to the top of the second spring, and the second connecting rod is fixedly connected to the side of the second limit plate away from the second spring.

[0012] Through the above technical solution, the second connecting rod can be limited by the second limiting piece to prevent the second connecting rod from being separated from the second sleeve.

[0013] As a further improvement of the above solution, the second connecting rod is sleeved inside the second sleeve, the top of the second connecting rod passes through the top of the second sleeve and extends, the top of the second connecting rod is fixedly connected to the mounting bracket, and the front of the mounting bracket is fixedly connected to the micro motor.

[0014] As a further improvement of the above solution, the output end of the micro motor is rotatably connected to the inside of the mounting frame, the output end of the mounting frame is fixedly connected to a roller, and the end of the roller away from the micro motor is rotatably connected to the back side of the mounting frame.

[0015] Through the above technical solution, the roller can be driven to rotate by the micro motor, so that the device can be moved along the main cable, thereby completing the detection of the main cable.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model rotates the rotating rod clockwise, which drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded rod to move upward, which pushes the installation box to move downward, and the installation box pushes the sliding rod to move upward. The sliding rod pushes the bottom end of the detection clamp to move upward, so that the detection clamp rotates around the fixed rod, thereby opening the detection clamp. The detection clamp is then sleeved on the main cable so that the main cable is located at the center of the detection clamp. The rotating rod is then rotated counterclockwise. Similarly, the detection clamp can be closed, which can effectively prevent the clamp from opening during detection, causing the detection clamp to separate from the main cable and affecting the detection.

[0018] The utility model detects that during the closing process of the clamp, the guide wheel will first contact the main cable, and then push the connecting rod to move toward the inside of the first sleeve. The connecting rod pushes the limit plate to move, and the limit plate compresses the first spring, so that the four guide wheels can all fit with the main cable, which can reduce the shaking of the device during movement.

[0019] The utility model works in such a way that in the process of moving the main cable to the center of the detection clamp, the main cable will contact the roller, and then the roller will move downward, the roller will push the mounting bracket to move downward, and the mounting bracket will push the second limit plate to move downward, thereby compressing the second spring. The reaction force of the second spring will make the roller fit more closely with the main cable, thereby increasing the friction between the roller and the main cable, and then start the micro motor, the operation of the micro motor drives the roller to rotate, and the rotation of the roller will make the device move along the main cable, so that the high-altitude detection of the main cable can be automatically completed, avoiding the danger of manual high-altitude detection.
