Construction method of tower type working condition crawler crane for pole bending or pole lifting without removing steel wire rope of hook head

Abstract

The invention discloses a construction method of tower type working condition crawler crane for pole bending or pole lifting without removing steel wire rope of hook head. The construction method comprises the following steps: manufacturing a support frame and a moving trolley, and arranging the support frame on the rear side of the moving trolley to form a movable bracket; in a tower type working condition crawler crane, detaching the hook head from a combined body of the hook head and a pulley block; erecting the pulley block with a steel wire rope on the supporting frame; supporting a rod head in the tower type working condition crawler crane on the moving trolley carried by a crawler crane manufacturer, and enabling the moving trolley carried by the crawler crane manufacturer to be connected with the moving trolley through a connecting rod; and commanding the tower type working condition crawler crane to perform rod bending or rod lifting operation. The construction method is easy to operate, the work of disassembling the steel wire rope from the pulley block is omitted, the hook head pulley block with the steel wire rope is stably supported and moved, the potential safety hazard that the steel wire rope is squeezed and damaged is eliminated, the workload is reduced, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of crawler crane operation auxiliary equipment, in particular to a construction method for avoiding disassembly of hook head wire ropes when crawler cranes are lying on the pole or lifting the pole under tower-type working conditions. Background technique [0002] Crane is a popular name for cranes, which are widely used in a series of heavy industrial products such as ships, equipment, machinery, and molds. When the crane is in use, its boom mainly has a single main arm working condition, a fixed jib working condition, a tower working condition (the jib can move the working condition) and other forms. When using the tower working condition, when the top of the boom is lying on the ground or lifting from the ground, it is necessary to first remove the hook pulley block from the top of the boom, and then use the mobile bracket to support the top of the boom. In the prior art , when the crawler crane in tower...

AI Technical Summary

Problems solved by technology

When using the tower working condition, when the top of the boom is lying on the ground or lifting from the ground, it is necessary to first remove the hook pulley block from the top of the boom, and then use the mobile bracket to support the top of the boom. In the prior art , when the crawler crane in tower working condition is on the ground to carry out the operation of lying on the pole or lifting the pole, the wire rope on the hook head must be removed from the combination of the hook head and the pulley block, so that the entire combination is separated from the crawler boom rod. Removing the wire rope will not only Time-consuming and labor-intensive, and it is easy to crush the wire rope, causing economic losses
