Problems solved by technology

However, in the double spreader operation mode, the suspension steel wire rope becomes a straight-eight figure when the upper frame is separated, and the spreader is twisted and swayed, resulting in inaccurate positioning, which leads to problems such as difficult box alignment and reduced operating efficiency.

Abstract

The invention provides a hoisting pulley assembly displacement mechanism. The hoisting pulley assembly displacement mechanism comprises a vehicle frame, and also comprises two sets of pulley assembly displacement devices symmetrically arranged along the center line of the vehicle frame, and each set of the pulley assembly displacement devices comprises: a track arranged on the vehicle frame; a seaside driving pulley trolley arranged on the track; a seaside hoisting pulley assembly fixed on the seaside driving pulley trolley; a landside driven pulley trolley arranged on the track; a landside hoisting pulley assembly fixed on the landside driven pulley trolley; a speed reduction motor arranged at one side of the seaside driving pulley trolley; and a speed reduction box, wherein the input shaft of the speed reduction box is coupled to the output shaft of the speed reduction motor. A quay crane having two single-suspender and double-suspender work modes and adopting the hoisting pulley assembly displacement mechanism can effectively alleviate the influences of inertia force and wind power on suspenders when the vehicle starts and brakes under a single hoisting system in order to improve the working efficiency of a driver.

Description

technical field [0001] The invention relates to hoisting machinery, in particular to a displacement mechanism of a hoisting pulley block. Background technique [0002] With the vigorous development of international container transportation, container yards, especially container yards that are dedicated to containers, have higher and higher requirements on the efficiency, automation, and failure rate of access equipment. With the "three super" type container ships put into use, 3E-class quay cranes came into being. It puts forward new functional requirements for the running trolley, and it is necessary to use double spreaders to lift double 40-foot containers at the same time under the single lifting system. [0003] The lifting pulley blocks on the existing running trolley are fixed on the vehicle frame, and the distance between the lifting pulley blocks is constant. In the single spreader operation mode, the wire rope connecting the hoisting pulley block on the frame and ...
