DETAILED DESCRIPTION

The limiting rod 303 is fixedly connected to one side of the bearing frame 302. The first spring 304 is sleeved on one side of the limiting rod 303. The adapter shaft 305 is fixedly arranged on one side of the roller 301. The rotating wheel 306 is fixedly connected to one side of the adapter shaft 305. An arc-shaped limiting groove is formed in one side of the rotating wheel 306. The sliding rod 307 is movably arranged in the arc-shaped limiting groove. The second spring 308 is fixedly connected to one side of the sliding rod 307. The push rod 309 is movably connected to one side of the sliding rod 307. The extension rod 310 is fixedly connected to one side of the push rod 309. The third spring 311 is sleeved on one side of the extension rod 310. The extension sleeve 312 is movably sleeved on one side of the extension rod 310. The extension sleeve 312 is fixedly arranged on one side of the positioning column 313. The positioning column 313 is fixedly arranged on one side of the positioning plate 314. The positioning plate 314 is fixedly connected to one side of the positioning frame 2.

[0037] The speed reduction protection assembly 3 further comprises an L-shaped rod 315, a driving rod 316, a damping cam 317 and a damping baffle 318. The L-shaped rod 315 is fixedly connected to one side of the push rod 309 away from the third spring 311. The driving rod 316 is movably connected to one side of the L-shaped rod 315. The damping cam 317 is fixedly connected to one side of the driving rod 316. The damping cam 317 is movably arranged at the bottom of the positioning frame 2. The distance between the damping cam 317 and the steel wire rope body 1 is 1 cm. The damping baffle 318 is symmetrically arranged with the damping cam 317 and the steel wire rope body 1 as the center. The distance between the damping baffle 318 and the steel wire rope body 1 is 1 cm.

[0038] The elastic force of the second spring 308 is smaller than the centrifugal force generated by the rotating wheel 306 when the steel wire rope body 1 exceeds the threshold speed. The second spring 308 is fixedly connected to the left and right sides of the sliding rod 307.

[0039] The arc-shaped limiting groove of the rotating wheel 306 is a involute structure. The active stroke of the sliding rod 307 in the arc-shaped limiting groove is in a linear relationship with the compression amount of the second spring 308.

[0040] The extension rod 310 and the extension sleeve 312 form an elastic extension structure through the third spring 311. The end of the extension sleeve 312 is fixedly connected to the positioning column 313 by welding or integral molding.

[0041] The surface of the damping cam 317 and the damping baffle 318 is provided with a high friction coefficient rubber layer, and the contact surface of the two with the steel wire rope body 1 is an arc-shaped groove structure.

[0042] The positioning plate 314 is provided with a plurality of bolt mounting holes, and the bolt mounting holes are distributed at equal intervals along the axial direction of the steel wire rope body 1.

[0043] The contact surface of the roller 301 with the steel wire rope body 1 is provided with a V-shaped guide groove, and the material of the roller 301 is nylon composite material.

[0044] It needs to be further explained that when the speed of the steel wire rope body 1 is abnormal, the adapter shaft 305 connected with the roller 301 drives the rotating wheel 306 to rotate synchronously. The centrifugal force generated by the rotating wheel 306 can extrude the slide rod 307 located in the arc-shaped limiting groove, and compress the second spring 308. If the speed of the steel wire rope exceeds the threshold value, the centrifugal force increases, and the slide rod 307 is extruded more strongly. At this time, the slide rod 307 pushes the push rod 309, the push rod 309 drives the driving rod 316 through the L-shaped rod 315, and then the damping cam 317 approaches the steel wire rope body 1, and the damping baffle 318 symmetrically arranged with the damping cam 317 also plays a role. The high friction coefficient rubber layer on the surface of the two, and the contact surface is an arc-shaped groove structure, can effectively increase the friction with the steel wire rope, slow down the speed of the overspeed steel wire rope, prevent the danger caused by the excessive speed, the roller 301 is movably installed on one side of the steel wire rope body 1, and the surface thereof in contact with the steel wire rope is provided with a V-shaped guide groove and is made of nylon composite material, which can play a good guiding role when the steel wire rope moves, prevent the steel wire rope from deviating, and the bearing frame 302, the limiting rod 303 and the first spring 304 work cooperatively to adaptively adjust according to the movement state of the steel wire rope. When the steel wire rope moves, the roller 301 rolls, the bearing frame 302 provides support, and the limiting rod 303 and the first spring 304 buffer and limit the movement of the roller 301, so as to buffer and protect the moving steel wire rope and ensure stable operation.

[0045] The implementation principle of the steel structure hoisting steel wire rope protection device in the embodiment of the application is as follows:

[0046] Firstly, the roller 301 plays a buffering and guiding role. The roller 301 is movably installed on one side of the steel wire rope body 1, contacts the steel wire rope body 1, and buffers the movement of the steel wire rope body 1 in the rolling process. Meanwhile, the V-shaped guide groove on the roller 301 ensures that the steel wire rope does not deviate when moving, and maintains a stable running track.

[0047] Secondly, the bearing frame 302, the limiting rod 303 and the first spring 304 cooperate to adaptively adjust. With the movement of the steel wire rope body 1, the bearing frame 302 supports the roller 301 to run, the limiting rod 303 cooperates with the first spring 304, and the force acting on the roller 301 is flexibly adjusted according to the movement state of the steel wire rope, so as to further guarantee the stable play of the buffering and guiding functions.

[0048] Then, the adapter shaft 305 and the rotating wheel 306 realize speed monitoring and early warning preparation. The adapter shaft 305 connects the roller 301 and the rotating wheel 306. When the steel wire rope body 1 drives the roller 301 to rotate, the adapter shaft 305 drives the rotating wheel 306 to rotate synchronously. The rotating wheel 306 rotates to generate centrifugal force, which extrudes the slide rod 307 in the arc-shaped limiting groove and compresses the second spring 308. Once the speed of the steel wire rope body 1 exceeds the threshold value, the centrifugal force significantly increases, and the extrusion force of the slide rod 307 becomes stronger, which prepares for the subsequent early warning action.

[0049] Next, the L-shaped rod 315 and the driving rod 316 transmit the action to the damping cam 317. When the slide rod 307 is extruded and moves, the L-shaped rod 315 fixedly connected with the push rod 309 acts, drives the driving rod 316, and makes the damping cam 317 close to the steel wire rope body 1.

[0050] Finally, the damping cam 317 and the damping baffle 318 jointly execute speed reduction braking. The damping cam 317 and the damping baffle 318 symmetrically arranged with the damping cam 317 increase the friction force with the steel wire rope after being close to the steel wire rope body 1, by virtue of the high-friction coefficient rubber layer on the surface and the arc-shaped groove contact surface, and brake the overspeed steel wire rope, so as to effectively guarantee the equipment operation safety.

[0051] The above are the preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
