DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1The present invention provides a cable insulation detection and fault warning positioning device, including a vehicle body 11 and a detection device 21 for insulation detection, the detection device 21 and the vehicle body 11 are detachably connected, and a connecting groove 12 is provided on the vehicle body 11. When not in operation, one end of the detection device 21 extends into the connecting groove 12, and the detection device 21 and the connecting groove 12 are slidably matched, and the other end of the detection device 21 is fixed to the gantry crane.

[0018] The detection device 21 needs to be connected to a cable. A socket 23 is provided on the side wall of the detection device 21. The cable that needs to be connected to the gantry crane is connected to the detection device 21. The detection device 21 is placed horizontally, and the socket 23 is located on the side of the detection device 21 facing away from the gantry crane to reduce damage to the cable caused by bending. The detection device 21 is then connected to the gantry crane to play a connecting role. A display screen 22 is fixedly installed on the upper end surface of the detection device 21 for displaying the detection status of the cable by the detection device 21 and responding in real time.

[0019] When the vehicle body 11 moves, the detection device 21 is separated from the vehicle body 11. The detection device 21 needs to maintain its own stability and ensure the stability of the cable. Two storage grooves 241 are provided on the lower end surface of the detection device 21. A support rod 24 is rotatably installed on the top wall of the storage groove 241. The support rod 24 is connected to the storage groove 241 through a torsion spring. One end of the torsion spring is connected to the support rod 24, and the other end is connected to the top wall of the storage groove 241. When the detection device 21 is connected to the vehicle body 11, the support rod 24 is pushed by the movement of the vehicle body 11, and the support rod 24 is flipped and stored in the storage groove 241. When the vehicle body 11 and the detection device 21 are separated, the support rod 24 is flipped and extended out through the torsion spring.

[0020] A connecting rod 42 is provided in the connecting groove 12, and a clamp 41 for clamping the cable is provided at the center of the connecting rod 42. The clamp 41 is annular, and a notch is provided at the upper end of the clamp 41 for the cable to extend into. A rolling groove is provided on the inner circumference of the clamp 41, and two connecting blocks are fixedly installed on the inner wall of the rolling groove. The connecting blocks are located on both sides of the notch. A circular column is rollingly connected in the rolling groove, and the two ends of the circular column are rotatably connected to the two connecting blocks respectively. The circular column is made of rubber material and has a certain deformation ability. The diameter of the circular column is slightly smaller than the diameter of the cable. The cable is fixed by the circular column. Since the circular column can roll, when the vehicle body 11 moves, the cable moves relative to the circular column, and the circular column can support the cable by rolling to make the cable move. The cable passes through the clamp 41, and the cable and the circular column maintain dynamic balance. The cable is clamped by the clamp 41 so that the cable is relatively in a tensioned horizontal state. A fixed block 31 is fixedly installed in the connecting groove 12, and the fixed block 31 is located on the side of the clamp 41 close to the detection device 21. A threading hole 32 is provided in the fixed block 31, and a temperature sensor 33 for detecting the temperature of the cable is fixedly installed in the threading hole 32. The temperature sensor 33 is connected to the display screen 22 through a wireless module for communication. The horizontal cable is detected by the temperature sensor 33. The vehicle body 11 moves, which drives the temperature sensor 33 to detect the movement of the cable. When an area with abnormal temperature appears on the cable, the display screen 22 simultaneously displays the corresponding data.

[0021] In some embodiments, a plurality of balls 411 are rotatably mounted on the inner wall of the clamp. During operation, the cable passes through the clamp 41 and the balls 411 abut against the circumference of the cable.

[0022] The body 11 is respectively provided with limiting grooves 44 on both side walls of the connecting groove 12, and the connecting rod 42 extends into and slides to fit the limiting groove 44. A return spring 43 is provided in the limiting groove 44, and the return spring 43 and the connecting rod 42 are fixedly connected. When the body 11 stops moving, the dynamic balance between the cable and the circular ring column is broken, and the cable is no longer horizontal. The return spring 43 causes the connecting rod 42 to move in the opposite direction, thereby keeping the cable in a tensioned state.

[0023] When the vehicle body 11 moves, the cable passes through the clamp 41 and the threading hole 32. The vehicle body 11 has a certain height. The cable is located on the bottom wall of the groove. The cable needs to be lifted upward. The vehicle body 11 is provided with a movable groove 14 that runs through the upper and lower parts. The movable groove 14 is located on the side of the connecting groove 12 that is away from the detection device 21. A movable rod 52 for moving the cable is provided in the movable groove 14. Both ends of the movable rod 52 are fixedly connected with eccentric wheels 51. A rotating shaft 53 is rotatably installed on the side wall of the movable groove 14. The rotating shaft 53 and the eccentric wheel 51 are fixedly connected. The rotating shaft 53 is connected to a motor. The rotating shaft 53 is driven by the motor to work, thereby driving the eccentric wheel 51 to rotate, and the eccentric wheel 51 lifts the cable through the movable rod 52.

[0024] A clamping slot 15 is provided between the connecting slot 12 and the movable slot 14. The vehicle body 11 is detachably connected with a clamping block 13. When working, the clamping block 13 extends into the clamping slot 15. The height of the cable is limited by the clamping slot 15 and the clamping block 13 to protect the cable.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
