[0046] The close-fitting mechanism 300 comprises: an electric push rod one 310 fixedly connected with the top of the support seat 110, one end of the electric push rod one 310 is fixedly connected with a square plate 311, a square frame 320 is slidingly inserted between both ends of the square plate 311, a plurality of elastic push rods one 312 are arranged and fixed between the outer walls of the square plate 311 and the square frame 320 at equal intervals, a plurality of square holes 321 are arranged and opened on the outer wall of the square frame 320 at equal intervals, a plurality of threaded holes 322 are arranged and opened on the outer wall of the square frame 320 near the bottom position at equal intervals, a square rod three 323 is slidingly arranged in the square hole 321, a plurality of circular holes 324 are opened on the outer wall of the square rod three 323 at equal intervals, a bolt two 325 is screwed into the threaded hole 322 and is slidingly connected with the circular hole 324, a rotating seat 326 is fixedly arranged at one end of the square rod three 323, and the rotating seat 326 is rotatably connected with a rubber roller two 327. Before installation, personnel can flexibly adjust the position of the rubber roller two 327 according to the diameter of the cable in each group of ring frames 211. This pre-adjustment mechanism ensures that multiple rubber rollers two 327 can accurately contact corresponding cables with different diameters at the same time when the electric push rod one 310 drives the square frame 320 to move downward with the elastic push rod one 312.

[0047] The brake mechanism 400 comprises: a square rod four 410 fixedly connected with the inner wall of the support seat 110, an electric push rod two 411 fixedly connected with the square rod four 410 at the middle, a square rod five 412 fixedly arranged at one end of the electric push rod two 411 and slidingly inserted with the inner wall of the support seat 110, the square rod five 412 is driven by the electric push rod two 411 to press the square rod two 212, so as to limit the rotation of the rubber roller two 327.

[0048] Specifically, during operation, cables of different diameters are placed on roller 120 between each set of ring frames 211. An operator uses an electric wrench to turn bolt 222, causing frame 220 to slide out of square groove 112. This separates the friction pad 221 on frame 220 from the friction block 215 on square rod 210, releasing the limiting action. Square rod 210, under the rebound of spring 214, causes each set of ring frames 211 to converge towards the center until rubber roller 213 contacts the cable, completing the initial limiting of cables of different diameters. Subsequently, the operator reverses the direction of bolt 222, moving frame 220 into square groove 112 until friction pad 221 contacts multiple friction blocks 215, limiting the current position of ring frame 211 and ensuring the cable is stably limited within a set of ring frames 211. During installation, the operator adjusts the extension length of elastic push rod 312 according to the diameter of the cable within each set of ring frames 211. The electric actuator 310 drives the square frame 320 downward, which in turn drives the elastic actuator 312, which is in the correct position, downward. Multiple rubber rollers 327 at the end of the elastic actuator 312 can simultaneously contact cables of different diameters and, due to the elastic rebound of the elastic actuator 312 itself, squeeze the cable with appropriate force, making the cable adhere tightly to the outer wall of the roller 120. When the cable is dragged, both the rubber rollers 327 and the roller 120 rotate. When braking the cable, the electric actuator 411 drives the square rod 412 to move, squeezing the movable square rods 212 in the same row, causing multiple square rods 212 to simultaneously contact the corresponding rubber rollers 327, limiting the rotation of the rubber rollers 327. Simultaneously, the electric actuator 310 continues to drive, keeping the rubber rollers 327 tightly against the cable, thus achieving the limiting and braking of the cable.

[0049] Example 1

[0050] like Figures 2-3 As shown, in this embodiment, the limiting mechanism 200 includes: a square rod 210, which is slidably inserted into the square groove 111; a spring 214, which is fixed between the outer wall of the square rod 210 and the inner wall of one side of the square groove 111; a ring frame 211, which is fixed to one end of the square rod 210, and the inner wall of the ring frame 211 is slidably connected to the outer wall of the roller 120; two square rods 212, one of which is fixed to the top of the ring frame 211 on one side, and the other slides on the top of the ring frame 211; a rubber roller 213, which rotates on the outer wall of one side of the square rod 212; a friction block 215, which is fixed to one end of the square rod 210; a frame 220, which is slidably inserted into the square groove 112, and a friction pad 221 is fixedly connected to the outer wall of one side of the frame 220; and a bolt 222, which rotates on the outer wall of the frame 220, and the bolt 222 is screwed into the square block 113.

[0051] In the embodiment, the limiting and releasing of the square rod 210 are achieved by twisting the bolt 222 to control the sliding of the frame 220, and the spring 214 is used to make the ring frame 211 automatically gather in the middle, and the rubber roller 213 is effectively attached to the cables with different diameters, thereby solving the problem that the existing V-shaped roller cannot effectively fix multiple cables with different diameters, preventing the cables from sliding or deviating, and ensuring the stability of the cables during operation. In addition, the friction pad 221 and the friction block 215 cooperate with each other to stably limit the ring frame 211 after the cable limiting is completed, so as to ensure that the cable always remains in the predetermined position, further enhancing the fixing effect of the cable and improving the reliability of the cable supporting device in complex working conditions.

[0052] As shown in Figure 4 In the embodiment, the close-fitting mechanism 300 includes: an electric push rod 310 fixedly connected to the top of the support seat 110, and the electric push rod 310 has a square plate 311 fixedly connected to one end thereof; a square frame 320 slidingly connected between both ends of the square plate 311; a plurality of elastic push rods 312 fixedly arranged at equal intervals between the square plate 311 and the outer wall of the square frame 320; a plurality of square holes 321 arranged at equal intervals on the outer wall of the square frame 320; a plurality of threaded holes 322 arranged at equal intervals on the outer wall of the square frame 320 near the bottom; a square rod 323 slidingly arranged in the square hole 321; a plurality of circular holes 324 arranged at equal intervals on the outer wall of the square rod 323; a bolt 325 screwing into the threaded hole 322 and slidingly connected with the circular hole 324; and a rotating seat 326 fixedly arranged at one end of the square rod 323 and rotatingly connected with a rubber roller 327.

[0053] In the specific implementation, before installation, personnel can flexibly adjust the position of the rubber roller 327 according to the diameter of the cable in each group of ring frames 211. This pre-adjustment mechanism ensures that when the electric push rod 310 drives the square frame 320 to move downward with the elastic push rod 312, multiple rubber rollers 327 can accurately contact the cables with different diameters at the same time. Compared with no pre-adjustment, the uniformity of the pressing force on the cables with different diameters is improved, ensuring that each cable can be tightly attached with the same force, avoiding cable shaking or displacement caused by poor contact, and improving the stability of the cable operation. Through the elasticity of the elastic push rod 312, the cable is tightly attached to the outer wall of the roller 120. This design avoids damaging the cable due to excessive pressure, ensures that the cable can be dragged, effectively reduces the relative sliding between the cable and the cable supporting device, and the elastic property of the elastic push rod 312 plays a buffering role. During the operation of the cable, the influence of the vibration and impact generated by the movement of the coal mining machine on the cable can be effectively alleviated, further protecting the cable from additional stress damage and improving the safety and stability of the cable operation.

[0056] In specific implementation, the square rod five 412 is driven by the electric push rod two 411 to extrude the square rod two 212, so as to limit the rotation of the rubber roller two 327 by the square rod two 212, and the electric push rod one 310 is driven to make the rubber roller two 327 tightly contact with the cable, so as to realize braking. Compared with the traditional air bag braking and uneven pressure distribution, the mechanism can accurately and stably brake the cable, effectively ensuring the safe operation of the cable.
