Tower crane boom packing device, system and method

Abstract

A tower crane boom packing device comprises two underframes and two upper-frames. Each underframe comprises an elongated bearing beam, two lugs, and a plurality of fastening parts; the lugs are disposed at two ends of the bearing beam respectively; the fastening parts are distributed on two sides of the bearing beam at intervals in the length direction of the bearing beam. Each upper-frame which is L shaped comprises a support rod and a stop rod which is arranged vertically downwards from one end of the support rod. The invention further provides a tower crane boom packing system and method using the tower crane boom packing device. When the tower crane boom packing device is used in loading, a whole boom can be loaded just by a single hoisting; transferring and delivering are more efficient; the segments of the boom packed are all firmly tied; especially, the different segments at different heights are isolated by the underframes and the upper-frames, so that mutual friction is avoided and wear is avoided.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a tower crane boom packing device, a packing system and a packing method for packing the boom of the tower crane during storage or transfer. Background technique [0002] In the field of construction machinery, many products have large weight and volume, and generally need to be dismantled into multiple parts for transportation, and assembled after arriving at the customer or another construction site. For example, for a tower crane, the tower body needs to be disassembled into standard sections for transportation, and the boom also needs to be disassembled into jib sections for easy transportation. The standard section is square, so it is more convenient to pack, but if the boom is variable section, it is more difficult to pack firmly. [0003] see figure 1 , the boom sections that need to be packaged include the first, second, third, fourth, fifth, and sixth boom section...

AI Technical Summary

Problems solved by technology

[0004] However, in the above packing methods, the steel belt and wooden block binding method is not strong enough; and it needs to be lifted twice when loading the car, which is more troublesome; at the same time, the second unit placed at the rear is difficult to place stably, and the two units are tied together It is also time-consuming and labor-intensive; during transportation, there will be friction between the boom sections, which will cause serious wear and tear on the paint on the surface of the boom sections, and even directly wear the diagonal rod of the boom, seriously affecting the appearance and quality of the product
