[0002] As a major attraction at tourist attractions, scenic ropeways not only provide convenient transportation but also enhance the fun of sightseeing. However, ropeway safety is crucial, directly impacting the lives of every passenger. As a key component in the operation of the load-bearing equipment, the condition of the ropeway's wire rope must be strictly monitored.

[0003] During the use of cableway wire rope, it will be deformed and worn due to the action of external forces. The tensile strength of the wire rope will be reduced after wear. The diameter of the wire rope is one of its important basic parameters. The change in diameter will have a significant impact on its carrying capacity and service life. When the diameter is less than a certain value, the load capacity of the wire rope will be lower than the safety standard. Continuing to use it is prone to overload and breakage accidents. Therefore, it must be inspected and maintained regularly.

[0004] Existing wire ropes are often measured for diameter by regular inspection. However, if the diameter of the wire rope changes during the inspection interval, the user has no way of knowing. During this period, the wire rope may break due to overload. Therefore, it is necessary to provide a tool that can monitor the wire rope in real time to detect the diameter of the wire rope so that changes in the wire rope diameter can be detected in a timely manner. A solution to the above problem is proposed below. Utility Model Content

[0022] See Figures 1 to 6As shown, a cableway wire rope position measuring tool includes a detection barrel 1 and several L-shaped support plates 2. There are four L-shaped support plates 2 in total. The L-shaped support plates 2 are symmetrically fixed on both sides of the detection barrel 1 in pairs. The detection barrel 1 is divided into an upper barrel 18 and a lower barrel 19. One end of the upper barrel 18 and the lower barrel 19 are hinged, and the other end of the upper barrel 18 and the lower barrel 19 are fixed by a lock. The inner walls of the upper barrel 18 and the lower barrel 19 are rotatably provided with rollers for guidance. The L-shaped support plates 2 are respectively fixed on the upper barrel 18 and the lower barrel 19. When it is necessary to detect the diameter of the wire rope, the detection barrel 1 can be opened, the wire rope is placed inside the detection barrel 1, and then the upper barrel 18 and the lower barrel 19 of the detection barrel 1 are fixed by a lock.

[0023] Mounting covers 3 are installed on the opposite surfaces of the two relative L-shaped support plates 2. A transmission wheel 4 is rotatably installed inside each mounting cover 3. An adjusting member 5 is installed between the bottom mounting cover 3 and the L-shaped support plate 2. The mounting cover 3 can be adjusted in height through the adjusting member 5. After the detection barrel 1 is installed, the position of the mounting cover 3 and the transmission wheel 4 can be adjusted by rotating the adjusting member 5 so that the transmission wheel 4 is in contact with the wire rope.

[0024] When the screw is adjusted to the specified position, the adjusting nut 7 can be turned to lock the bolt through the cooperation between the adjusting nut 7 and the L-shaped support plate 2 to prevent the screw from rotating in the subsequent use.

[0025] The upper mounting cover 3 and the L-shaped support plate 2 are connected by a telescopic rod. When the upper barrel 18 is flipped and fixed with the lower barrel 19, the upper barrel 18 will drive the L-shaped support plate 2 and the mounting cover 3, and the transmission wheel 4 and the wire rope to come into contact. When the transmission wheel 4 comes into contact with the wire rope, the transmission wheel 4 will be squeezed by the wire rope and pushed upward, and the transmission wheel 4 will squeeze the telescopic rod.

[0026] The telescopic rod includes a connecting rod 1 9, a connecting rod 2 10 and a connecting spring 11. The connecting rod 1 9 is fixed on the L-shaped support plate 2. The end of the connecting rod 1 9 away from the L-shaped support plate 2 is provided with a wide groove 12. The connecting rod 2 10 is slidably set in the wide groove 12. The connecting spring 11 is set inside the wide groove 12. One end of the connecting spring 11 is fixed to the bottom of the wide groove 12, and the other end of the connecting spring 11 is fixedly connected to the connecting rod 2 10. The end of the connecting rod 2 10 away from the connecting spring 11 is fixedly connected to the mounting cover 3. The transmission wheel 4 will squeeze the mounting cover 3, and the mounting cover 3 will squeeze the connecting rod 2 10. The connecting rod 2 10 will squeeze the internal connecting spring 11. The connecting spring 11 will generate elastic force when squeezed, and the connecting rod 2 10 will be squeezed in the opposite direction by the elastic force of the connecting spring 11. The mounting cover 3 and the transmission wheel 4 are pushed by the connecting rod 2 10, so that the transmission wheel 4 can be in close contact with the wire rope.

[0027] A guide rod 13 is provided on both sides of the telescopic rod, one end of the guide rod 13 is fixedly connected to the mounting cover 3, and the other end of the guide rod 13 passes through the L-shaped support plate 2. By installing the guide rods 13 on both sides, it can play a guiding role, realize the linear movement of the transmission wheel 4, and prevent the transmission wheel 4 from deviating during the movement and causing errors in subsequent monitoring.

[0028] A displacement sensor 6 is also installed on the upper L-shaped support plate 2. The displacement sensor 6 corresponds to the mounting cover 3. The displacement sensor 6 adopts a laser displacement sensor 6. The laser displacement sensor 6 is used to detect the distance between the mounting cover 3 and the L-shaped support plate 2. The wire rope passes between the two guide wheels. When the diameter of the wire rope changes, the mounting cover 3 will be displaced through the telescopic rod. The distance change caused by the mounting cover 3 is checked by the laser displacement sensor 6. A controller 17 is also installed on the upper L-shaped support plate 2. The controller 17 is telecommunication-connected to the displacement sensor 6. The laser displacement sensor 6 will transmit the detected data to the controller 17. The controller 17 is equipped with a processor and a wireless generator. The controller 17 will process the data detected by the laser displacement sensor 6 and transmit the processed data to the background staff through the controller 17, so that the background staff can monitor the diameter change of the wire rope in real time to prevent the diameter of the wire rope from being changed in time.

[0029] A support plate 14 is fixed to the outer walls of the two opposing mounting covers 3, a main ruler 15 is fixed to the end of the lower support plate 14 away from the mounting cover 3, and a sub-rule 16 is fixed to the end of the upper support plate 14 away from the mounting cover 3. Both the main ruler 15 and the sub-rule 16 are provided with scale lines, and the two scale lines are set correspondingly. By installing the main ruler 15 and the sub-rule 16 on the two mounting covers 3, the staff can directly observe the diameter of the wire rope through the main ruler 15 and the sub-rule 16 during on-site inspection without having to measure with a ruler.

[0030] The detection barrel 1 can also be replaced by a wire rope detector. The TCK wire rope detector can detect the wire rope in real time online 24 hours a day. Once there is a broken wire, an alarm will be sounded immediately and the signal will be transmitted to the control platform. The operator can receive the alarm in time indoors. The wire rope detector uses a weak magnetic method for detection and determines whether the wire rope is fatigued, worn, broken, or corroded through the change curve of the magnetic field potential energy in the wire rope.
