[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a bridge cable safety maintenance device, including an upper mounting block 1, a distance adjustment mechanism 3 and a reinforcement mechanism 4. There are two groups of upper mounting blocks 1, and two groups of lower mounting blocks 2 are arranged below the upper mounting block 1; the distance adjustment mechanism 3 is arranged on the top of the upper mounting block 1. The distance adjustment mechanism 3 includes a connecting block 301 and a bidirectional lead screw 302. The tops of the two groups of upper mounting blocks 1 are respectively fixedly connected to the bottom of a group of connecting blocks 301. The inside of the connecting block 301 is threadedly connected to the outer wall of the two groups of bidirectional lead screws 302, and the connecting blocks 301 are symmetrically arranged on the bidirectional lead screws 302; the reinforcement mechanism 4 is arranged below the upper mounting block 1. The reinforcement mechanism 4 includes a fixing plate 401 and a threaded rod 402. A group of fixing plates 401 are respectively fixedly installed on the front and rear sides of the lower mounting block 2, and a threaded rod 402 is rotatably installed on the top of the fixing plate 401.

[0022] The distance adjustment mechanism 3 further includes a limiting rod 303, an annular block 304 and an auxiliary rod 305. The outer wall of the bidirectional lead screw 302 is fixedly connected to the inside of the annular block 304. A plurality of annularly distributed auxiliary rods 305 are fixedly installed on the outer wall of the annular block 304. The inside of the connecting block 301 is slidably connected to the outer wall of the limiting rod 303. Partition plates are arranged at both ends of the limiting rod 303, which is convenient for adjusting the distance between the rotating rollers 6, and can be erected on bridge cables with different spacing distances, enabling the device to move stably on the cable, improving the flexibility and practicality of the device during maintenance.

[0023] The reinforcement mechanism 4 also includes a knob 403 and an internal thread block 404. One end of the threaded rod 402 passes through the fixed plate 401 and is fixedly connected to the top of the knob 403. An internal thread block 404 is fixedly installed on the front and rear sides of the upper mounting block 1 respectively. The outer wall of the threaded rod 402 is connected to the internal thread of the internal thread block 404, so that the rotating roller 6 can fit tightly with the outer wall of the cable, thereby increasing the friction between the rotating roller 6 and the cable, so that the device can be suitable for cables of different sizes.

[0024] The bottom of the upper mounting block 1 and the top of the lower mounting block 2 are both provided with placement grooves 5 .

[0025] A rotating roller 6 is rotatably installed on the front and rear inner walls of the placement groove 5, and a reduction motor 7 is fixedly installed on the front side of one group of upper mounting blocks 1 and the rear side of another group of reduction motors 7, and the output shaft of the reduction motor 7 is fixedly connected to one end of the rotating roller 6.

[0027] Working principle: When the device is in use, the bidirectional lead screw 302 is rotated by toggling the auxiliary rod 305. Under the limit of the limit rod 303, the bidirectional lead screw 302 drives the two groups of connecting blocks 301 to move in relative directions. The distance between the two groups of upper mounting blocks 1 is adjusted according to the distance between different cables. The upper mounting block 1 is placed upside down on the cable, and then the lower mounting block 2 is buckled under the cable and the threaded rod 402 is aligned with the hole position of the internal thread block 404. The threaded rod 402 is rotated by the knob 403 to screw the threaded rod 402 into the internal thread block 404, and the lower mounting block 2 and the upper mounting block 1 are merged. At the same time, the rotating roller 6 and the cable are tightly fitted, and then the reduction motor 7 is turned on to drive the rotating roller 6 to rotate. The friction between the rotating roller 6 and the reduction motor 7 is used to move the device on the cable, and the maintenance component 8 is turned on to inspect the cable surface during movement.
