Embodiment 1

[0028] This embodiment is the most basic implementation.

[0029] This example provides Figure 1-2 The shown two-layer four-rope safety manned broken rope balancing device includes a reel 5, a steel wire rope 13, a balance lever 7 and a pulley block. A group of steel wire ropes 13 are respectively wound around the rope grooves at both ends of the reel 5, and each The group of steel wire ropes 13 is superimposed and wound by the main bearing rope 8 and the auxiliary bearing rope 9 to form a double-layer structure; corresponding to each group of steel wire ropes 13 under the reel 5, a balance lever 7 and a pulley block are provided, and the pulley block includes a main load pulley block 11 arranged in parallel. And the auxiliary load pulley block 10, the balance lever 7 is provided with a hinge point that is used to be hinged on the frame 6 and can make the balance lever 7 swing up and down; the main load rope 8 is connected to one end of the balance lever 7 after bypassing the...

Embodiment 2

[0032] This example provides Figure 1-2 The shown two-layer four-rope safety manned rope breaking balance device includes a frame 6, a reel 5 and a driving mechanism arranged on the frame 6, and a rope groove at both ends of the reel 5 is respectively wound with a A group of steel wire ropes 13, two groups of steel wire ropes 13 are respectively wound on the rope grooves at both ends of the drum 5 in different directions of rotation and are all wound out from the front side of the drum 5; each group of steel wire ropes 13 is superimposed by the main bearing rope 8 and the auxiliary bearing rope 9 Winding forms a double-layer structure, the main load-bearing rope 8 is wound on the rope groove as the first layer, and the auxiliary load-bearing rope 9 is lagged behind the first layer as the second layer and wound between the two turns of the steel wire rope 13 of the first layer. between.

Abstract

The invention discloses a two-layer four-rope safe manned broken rope balancing device, which belongs to the technical field of hoisting. It includes a drum, a steel wire rope, a balance lever and a pulley block. A group of steel wire ropes are wound around the rope grooves at both ends of the drum. Each group of steel wire ropes is superimposed and wound by the main load rope and the auxiliary load rope to form a double-layer structure; the bottom of the drum corresponds to each group The steel wire ropes are all equipped with a balance lever and a pulley block. The balance lever is provided with hinge points for connecting to the frame so that the two ends of the balance lever can swing up and down. The pulley block includes a main load pulley block and a secondary load pulley block. After passing the main bearing pulley block, it is fixed on the first end of the balance lever, and the auxiliary load rope is fixed on the second end of the balance lever after passing around the auxiliary load pulley block. The invention not only occupies a small area, but also has high safety and reliability. When one of the steel wire ropes breaks, the remaining three steel ropes can bear the weight, which can ensure the safety and stability of hoisting after the steel wire ropes are broken.

Description

technical field [0001] The invention relates to a hoisting mechanism, in particular to a two-layer four-rope safety manned broken rope balancing device. Background technique [0002] Generally speaking, the reel of the hoisting mechanism is a single-head spiral rope groove. In order to improve the safety level of the manned hoisting mechanism, two sets of reel reducers and motors are often arranged. After failure, another set of mechanisms can ensure the safety of the manned platform or crane. However, this arrangement method not only occupies a large area, it cannot be applied to installation occasions with small space, and the mechanism is relatively complicated, requiring electrical or technical measures for synchronous operation with the mechanism, which reduces the reliability of the equipment. [0003] In the prior art, the publication number is CN209428024U, and the publication date is September 24, 2019. The invention patent document named "Electric Hoist with Singl...
