Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and specifically to a cable fatigue detector. Background Art

[0002] During long-term use, cables are prone to damage. If not discovered in time, the cable may break, losing its tensioning force, which can easily cause the supported object to lose its force support and lead to accidents such as collapse. Currently, cable detection usually uses manual inspections to observe whether there are cracks, breaks, or other defects on the cable surface, and uses calipers to measure the cable diameter to check if it is within the specified range. This method is inefficient and not very accurate. The main problem solved by this device is to perform regular inspections on cables and promptly detect defects. Summary of the Invention

[0003] The purpose of the present invention is to provide a cable fatigue detector to overcome the above-mentioned defects in the prior art.

[0004] The present invention is realized through the following technical solutions.

[0005] A cable fatigue detector of the present invention includes an upper arc-shaped cover and a lower arc-shaped cover. The upper arc-shaped cover is rotatably connected to the lower arc-shaped cover. The upper arc-shaped cover and the lower arc-shaped cover are closed to form a through groove. An adaptive telescopic rod is provided on the upper side of the upper arc-shaped cover, and the adaptive telescopic rod is also provided on the lower side of the lower arc-shaped cover. Two groups of first rotating frames are symmetrically hinged to the left and right of the axis of the adaptive telescopic rod. A connecting rod is provided at the end of the first rotating frame, and a second rotating frame is provided at the end of the connecting rod. A first detection frame is hinged at the end of the second rotating frame. A measuring roller is rotatably provided on the first detection frame, and the measuring roller is also provided on the lower side of the first detection frame. A second detection frame is rotatably provided on the lower measuring roller. The second detection frame is slidably connected to the first detection frame. A detection device is provided between the second detection frame and the first detection frame. An extension body is provided on the side of the first detection frame, and the extension body is also provided on the side of the second detection frame. A tension spring is provided between the upper and lower extension bodies. The second detection frame is rotatably connected to the lower second rotating frame. A driving pulley is rotatably provided on the lower side of the lower arc-shaped cover, and a rotating belt is provided on the driving pulley.

[0006] In a further technical solution, a sliding rod is provided on the lower side of the first detection frame. An avoidance groove is provided in the middle of the sliding rod, and a rack is provided on the side of the avoidance groove. An upwardly open detection chute is provided on the upper side of the second detection frame. The sliding rod extends into the detection chute and is slidably connected in the detection chute. A detection gear is rotatably provided on the wall of the detection chute, and the detection gear meshes with the rack. An angle detector is provided in the first detection frame, and the sensing shaft of the angle detector is connected to the axis of the detection gear.

[0007] Further technical solution: A slider is slidably arranged in the detection chute, and the lower end of the sliding rod is rotatably connected to the slider.

[0008] Further technical solution: A belt motor is arranged on the lower side of the lower arc-shaped cover. Two groups of adjusting telescopic rods are hinged between the belt motor and the lower arc-shaped cover, and the shaft of the belt motor is connected to the driving belt pulley.

[0009] Further technical solution: A bracket is arranged outside the first detection frame. A rope-climbing motor is installed on the bracket. The shaft of the rope-climbing motor is provided with a driving shaft, and the shaft of the driving shaft is connected to the axis of the measuring roller.

[0010] Further technical solution: The rotating belt is an unclosed belt. Extension bodies are arranged at both ends of the rotating belt. Fixed claws are arranged on the extension bodies. Fixed grooves are arranged on the fixed claws. The two fixed claws can cooperate to be clamped. After the two fixed claws cooperate, the two fixed grooves form a complete groove. A fixed rod is arranged in the groove formed by the two fixed grooves, and the fixed rod can connect the two ends of the rotating belt.

[0011] Further technical solution: Magnets are arranged at the ends of the upper arc-shaped cover and the lower arc-shaped cover. When the upper arc-shaped cover and the lower arc-shaped cover are rotated and closed, the two magnets can attract each other to lock the upper arc-shaped cover and the lower arc-shaped cover.

[0012] Advantages of the present invention:

[0013] A cable fatigue detector of the present invention can measure the diameter of a cable by arranging two groups of measuring rollers which are relatively slidably connected to each other, with the sides of the measuring rollers being concave and the sides of the two measuring rollers abutting against the cable. In order to measure the cable diameter comprehensively and accurately, the device is provided with an upper arc-shaped cover, a belt motor and a rotating belt. The belt motor can drive the device to rotate around the axis of the cable, so that the measured values of the measuring rollers are more comprehensive and accurate.

[0014] A first rotating frame, a connecting rod, a second rotating frame, an adaptive telescopic rod, etc. are arranged between the front and rear groups of measuring rollers of the device. The telescopic expansion of the adaptive telescopic rod can adjust the distance between the front and rear groups of measuring rollers, so as to adapt to different lay lengths between different cables. By arranging a rope-climbing motor, the rope-climbing motor drives the measuring rollers to rotate, and the device can crawl on the cable to be measured, can measure the cable at a relatively high height, improves the degree of unmanned operation, can adapt to harsh environments, and improves the safety of personnel;

[0015] By setting a belt motor, a rotating belt, etc., this device can be driven to move in a circular motion around the cable. The advantage of using a rotating belt is that it can adapt to cables of different diameters. Moreover, the thicker the cable, the larger the contact area of the rotating belt, which increases the friction. Using a rotating belt can provide a stable rotating effect for this device and a stable environment for measuring the change in the diameter of the cable. BRIEF DESCRIPTION OF THE DRAWINGS
