Crane and lifting operation mechanism thereof

Abstract

The invention discloses a crane and a lifting operation mechanism thereof. The lifting operation mechanism comprises a front roller, a rear roller, a head pulley block, a tail pulley block, a hanger feeding pulley block, a trolley pulley block, a front steel wire rope group connected with the front roller, the head pulley block, the trolley pulley block and the hanger feeding pulley block, and a rear steel wire rope group connected with the rear roller, the tail pulley block, the trolley pulley block and the hanger feeding pulley block, wherein running of a trolley is controlled by controlling rotation in the same direction of the front roller and the rear roller; lifting of a hanger is controlled by controlling reversed rotation of the front roller and the rear roller. According to the lifting operation mechanism of the crane, the structure is greatly simplified, and the processing and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a crane, in particular to a hoisting and operating mechanism and a crane with the hoisting and operating mechanism. Background technique [0002] With the development of the shipping industry, especially the development of container transportation, the role of quayside container cranes (referred to as quayside cranes) is becoming more and more important, and the design and manufacturing level of quayside container cranes is also getting higher and higher. [0003] In the prior art, the hoisting of the quay crane spreader and the operation of the crane trolley are realized by two sets of independent mechanisms, namely the hoisting mechanism and the running mechanism. [0004] Among them, the structure of the lifting mechanism is as follows: figure 1 As shown, the lifting mechanism includes a reel device 31, a tail pulley block 32 arranged at the tail of the quay bridge, a trolley pulley block 33 arranged on a trolley 38, a spre...

AI Technical Summary

Problems solved by technology

[0012] Aiming at the problems existing in the prior art, the object of the present invention is to provide a hoisting and operating mechanism to solve the technical problems of the prior art that the hoisting and operating system of the quay crane is complicated in structure and the processing and manufacturing costs are relatively high.
