A crane with pulley beam moving equipment

Abstract

The invention discloses a crane with pulley beam moving equipment, and relates to the technical field of cranes. The crane with the pulley beam moving equipment includes a moving beam, the two ends of the moving beam are fixed with support legs, the front side and the rear side of the moving beam are provided with sliding grooves, and the main body of the pulley beam moving equipment is arranged inside the sliding groove , the main body of the pulley beam mobile device includes two sets of pulleys, a driving motor and a connecting rod. The crane with pulley beam mobile equipment can drive the pulley to rotate by setting the drive motor, so that the pulley can move left and right inside the sliding groove. During the movement of the pulley, the laminating plate will always be in contact with the bottom of the inner wall of the sliding groove, and at the same time clean the scraper The sand on the top and bottom of the inner wall of the sliding groove will be scraped off to prevent the movement of the pulley from being blocked by the sand on the top and bottom of the inner wall of the sliding groove, and the noise during the movement of the pulley can also be reduced.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a crane with pulley beam moving equipment. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane, aerial crane, and crane. The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall cement columns or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. [0003] Installing the pulley beam mobile equipment on the bridge crane can con...

AI Technical Summary

Problems solved by technology

[0003] Installing the pulley beam mobile equipment on the bridge crane can control the movement of the hoisted heavy objects. However, in some places such as construction sites with severe dust, the sand in the air will enter the slide rails of the pulley beam mobile equipment, thereby As a result, there are impurities between the pulley and the slide rail, which affect the movement of the pulley, causing the speed of the pulley to change, and when lifting heavy goods, due to the large inertia of the heavy object, the pulley beam moves during the movement of the heavy object. The speed change of the equipment will cause the heavy object to swing under the action of inertia, which will cause the heavy object to swing back and forth and impact the nearby goods or operators, posing a safety hazard
