[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5 As shown, the utility model provides a cable force monitoring and identification device, including a slip ring 202, a swivel 204 and a base 4, the slip ring 202 has a cavity inside, the cavity of the slip ring 202 is fitted with a sensor 203, the inside of the swivel 204 is tightly provided with a cable 3, the outside of the swivel 204 is tightly provided with a telescopic rod 205, the outside of the telescopic rod 205 is sleeved with a spring 206, the other end of the spring 206 is tightly provided with a support frame 208, the inside of the support frame 208 is penetrated by a rotating shaft 207, the outside of the rotating shaft 207 is sleeved with a roller 209, the roller 209 rotates inside the support frame 208, and the roller 209 rotates inside the support frame 208. When the sensor 203 is attached to the inner wall of the sensor 203 and slides to the thicker position of the rope 3 through the slip ring 202, the rope 3 squeezes the telescopic rod 205 to deform in the direction of the inner wall of the cavity of the slip ring 202 and compresses the spring 206 outside the telescopic rod 205. At this time, the other end of the spring 206 squeezes the support frame 208 to slide inside the slip ring 202, and the roller 209 inside the support frame 208 slides driven by the rotating shaft 207. At this time, the roller 209 is pressed against the sensor 203. At this time, according to the degree of compression of the sensor 203, the magnitude of the rope force can be calculated, and the safety factor of the rope 3 can be judged according to the magnitude of the numerical value.

[0028] Specifically, a cavity is opened inside the base 4, and a motor 401 is arranged inside the cavity of the base 4. The end of the main shaft of the motor 401 is rotatably connected to a rotating wheel 403, and the outer side of the rotating wheel 403 is meshingly connected to a central gear 402. The main shaft end of the motor 401 drives the rotating wheel 403 to rotate, and the rotating wheel 403 drives the central gear 402 to rotate, thereby changing the angle.

[0029] Furthermore, the outer side of the central gear 402 is fixedly connected to a base 5, the outer side of the base 5 is rotatably connected to a rotating rod 501, the top of the rotating rod 501 is fixedly connected to a camera 502, and the camera 502 on the outer side of the rotating rod 501 can be rotated toward the camera 502, so that the shooting range is wider.

[0030] Furthermore, a reinforcing rib 201 is fixed to the outer side of the slip ring 202 by welding, and a notch is provided on the right side of the reinforcing rib 201 , so that the slip ring 202 is embedded into the inner part of the reinforcing rib 201 , thereby achieving the purpose of fixation.

[0031] It is worth mentioning that the left side of the reinforcing rib 201 is fixedly connected to a fixing plate 2, and the left side of the fixing plate 2 is connected to a display screen 1 through a threaded bolt. By setting the display screen 1 outside the fixing plate 2 and projecting the value of the sensor 203 through the display screen 1, it is clearer to watch during detection.

[0032] It is worth noting that the slip ring 202 is sleeved inside the cavity of the base 4, and the base 4 is rotatably connected to the outside of the slip ring 202. The base 4 is driven to rotate on the slip ring 202 by the central gear 402, thereby facilitating a more comprehensive detection of the rope 3.

[0033] It is worth mentioning that there are six groups of telescopic rods 205, springs 206, rotating shafts 207, support frames 208, and rollers 209, which are evenly arranged on the outside of the rotating ring 204. By setting up six groups of telescopic rods 205, springs 206, rotating shafts 207, support frames 208, and rollers 209, the rollers 209 can slide more smoothly on the inner wall of the cavity of the slip ring 202.

[0034] Working Principle:.

[0035] First, the staff puts the swivel 204 on the outside of the rope 3, and adds the sensor 203 on the outside of the slip ring 202. When the rope 3 needs to be tested, it is only necessary to slide the roller 209 passing through the inside of the slip ring 202 along the inner wall of the cavity of the slip ring 202 along the bottom of the rope 3 to a higher position. When it slides to a position where the rope 3 is thicker, the rope 3 squeezes the telescopic rod 205 to deform in the direction of the inner wall of the cavity of the slip ring 202, and compresses the spring 206 on the outside of the telescopic rod 205. At this time, the other end of the spring 206 squeezes the support frame 208 to slide into the inside of the slip ring 202, and the roller 209 inside the support frame 208 slides driven by the rotating shaft 207. At this time, the roller 209 is pressed against the sensor 203. At this time, according to the degree of compression of the sensor 203, the magnitude of the rope force can be calculated, and the rope 3 can be judged according to the magnitude of the numerical value.

[0036] And when the slip ring 202 slides on the outside of the rope 3, the motor 401 inside the base 4 sleeved on the outside of the slip ring 202 rotates, and at this time, the motor 401 drives the top wheel 403 to rotate, and the wheel 403 drives the central gear 402 to rotate, and the outside of the base 4 is fixedly connected with the base 5. When the central gear 402 rotates, it drives the outer base 5 to rotate, and the rotating rod 501 rotates on the outside of the base 5. At this time, the camera 502 on the top of the rotating rod 501 also rotates synchronously, and the camera 502 can be rotated, and the outside of the rope 3 can be detected in real time. The test result is accurate, and the maintenance efficiency is improved. In this process, there is no need for staff to climb, and there is no need to consume a lot of manpower and material resources. The value of the sensor 203 is projected through the display screen 1, so that it is clearer to watch during detection.
