When the original steel wire rope wheel 20 needs to be emergently braked under special conditions, the handle 38 is rotated, the handle 38 controls the eccentric wheel 36 to rotate downwards in a region with larger eccentricity and enables the pressing bearing 37 to be in pressing fit with the end part of the long rod of the brake rod 11, then the brake block 4 is in pressing fit with the outer edge of the brake wheel 3, the angular speed of the brake wheel 3 is reduced, the angular speed of the original steel wire rope wheel 20 fixed with the roller 2 is reduced, and the handle 38 is further rotated to enable the original steel wire rope wheel 20 to be completely stopped. When the original steel wire rope wheel 20 is not required to be braked emergently, the handle 38 is rotated, the handle 38 controls the eccentric wheel 36 to rotate downwards in the area with smaller eccentricity, so that the pressing bearing 37 is separated from the brake lever 11, and the normal use of the brake lever 11 is prevented from being influenced.

In order to quickly release the steel cable 35 on the steel cable original wheel 20, as shown in fig. 2, there are two annular grooves on the tension wheel 6 and three annular grooves on the second guide wheel 14. The wire rope 35 transmitted by the first guide wheel 13 passes through the first annular groove of the second guide wheel 14 and then is wound to the first annular groove on the tension wheel 6, then is wound to the second annular groove of the second guide wheel 14 and then is continuously wound to the second annular groove on the tension wheel 6, and then passes through the third annular groove of the second guide wheel 14 and then is connected to the wire rope winding and bundling device.

Preferably, as shown in fig. 2, the upper surface of the clamping seat 18 is an arc concave structure, a clamping groove for allowing the bearing 19 to be clamped is formed in the clamping seat 18, two axial ends of the bearing 19 are limited in the clamping groove, and the roller 2 does not interfere with the clamping seat 18.

Furthermore, in order to reduce the abrasion of the brake block 4 to the brake wheel 3, a brake pad 39 which is in friction fit with the brake wheel 3 is detachably mounted on the brake block 4 and the outer edge of the brake wheel 3 which are pressed against the brake matching surface.

In this embodiment, since the frame 1 vibrates during the releasing process of the wire 35 on the wire wheel 20, in order to avoid the brake lever 11 from greatly moving on the guide bar 8, as shown in fig. 6, a snap ring 41 is fixedly arranged on the guide bar 8 above the brake lever 11, and the snap ring 41 does not affect the braking function of the brake lever 11.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
