Problems solved by technology

[0002] The hook block is an important working part of the crane. In the traditional hook block, the pulleys are arranged in parallel. Due to the distance between the drum and the fixed pulley block, there is a large angle between the hook pulley and the wire rope on the drum and the fixed pulley. When the wire rope is moving, it is easy to brace the groove (the wire rope comes out of the pulley groove). At the same time, due to the large angle, the wire rope will rub against the pulley rim for a long time, which will shorten the life of the wire rope and affect the lifting safety.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0023] Such as Figure 1 to Figure 4 The shown hook block pulley installation structure includes two oppositely arranged side plates 1 and a first pulley block 2 and a second pulley block 3 arranged between the two side plates 1, the side plates 1 are vertically arranged, and the two sides The plates 1 are connected and fixed at three points by the first pulley shaft 22, the second pulley shaft 32 and the horizontal shaft 5 of the hook. The wheel shaft 22 is located on the same horizontal plane, and the hook horizontal shaft 5 is located below the horizontal plane where the first pulley shaft 22 and the second pulley shaft 32 are located. The middle part of the horizontal shaft 5 is provided with a suspension hook 6 through a bearing sleeve.

[0024] Depend on figure 2 It can be seen that the first pulley set 2 and the second pulley set 3 are mirror...

Abstract

The invention discloses a hook assembly pulley installation structure. The hook assembly pulley installation structure comprises two opposite side plates, a first pulley block and a second pulley block, which are arranged between the two side plates, the first pulley block and the second pulley block are arranged in a mirror symmetry manner, the first pulley block comprises two first pulleys which are arranged symmetrically, the two first pulleys are supported between the two side plates through a first pulley shaft, the first pulleys are obliquely arranged, and an angle alpha is formed between the radial central axis of each first pulley and the corresponding side plate. The hook assembly pulley installation structure is simple and novel in structure, convenient to install and high in universality, the jumping risk of a wire rope can be reduced, the application reliability of a crane can be guaranteed, the abrasion of the wire rope can be alleviated, and the service life of the wire rope can be effectively prolonged.

Description

technical field [0001] The invention relates to a crane component, in particular to a hook group pulley installation structure. Background technique [0002] The hook block is an important working part of the crane. In the traditional hook block, the pulleys are arranged in parallel. Due to the distance between the drum and the fixed pulley block, there is a large angle between the hook pulley and the wire rope on the drum and the fixed pulley. When the wire rope moves, it is easy to support the groove (the wire rope comes out of the pulley groove), and because of the large angle, the wire rope rubs against the pulley rim for a long time, which shortens the life of the wire rope and affects the lifting safety. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a hook group pulley installation structure, which can reduce the risk and wear speed of the wire rope bracket of the hook group, improve the safety of th...
