Self-dismounting amplitude change device of track crane superlift counterweight

Abstract

The invention discloses a self-dismounting amplitude change device of a track crane superlift counterweight. The device comprises a main arm system connected to the front end of a host machine, a superlift mast and a mast; the main arm system is connected with the superlift mast through a superlift amplitude change system; the mast is connected with the superlift mast through a pull plate, and is connected with the host machine through a main amplitude change system; the tail end of the host machine is connected with the superlift mast through a superlift counterweight amplitude change device and a superlift counterweight hanging pull plate; and the superlift counterweight hanging pull plate is connected with a superlift counterweight. In conclusion, the device is convenient for use and obvious in effect, can satisfy total self-dismounting of the track crane superlift counterweight amplitude change device and convenience for shifting of a track crane under such mounting conditions as track crane superlift working condition and arm frame replacing working condition, improves the dismounting convenience of the track crane superlift counterweight amplitude change device and whole machine, saves an auxiliary crane, reduces the labor intensity, and improves the mounting efficiency.

Description

technical field [0001] The invention relates to an auxiliary tool for installing a superlift balance weight, which belongs to the field of engineering machinery, in particular to a self-disassembly and assembly luffing device for a superlift balance weight of a crawler crane. Background technique [0002] Counterweights are used in many construction machinery, mainly to meet the performance of the car body and maintain the stability of the whole vehicle. Taking the crawler crane as an example, in order to improve the operation performance, the crawler crane is usually equipped with a movable counterweight-superlift counterweight, and the lifting performance of the whole vehicle can be improved by changing the range of the superlift counterweight. [0003] The installation sequence of the superlift working condition is to install the mast, the superlift mast and the tie plate between the superlift mast and the mast, connect the suspension tie plate of the superlift balance we...

AI Technical Summary

Problems solved by technology

[0004] When changing the boom length or changing the working condition in superlift working conditions, it is necessary to disconnect the superlift luffing system. At this time, the whole system at the rear of the superlift mast cannot be self-balanced. The mast must be folded back. At this time, the main boom system of the whole vehicle, the superlift mast, and the mast are separated from the superlift counterweight luffing system. The luffing device of the lifting balance weight is hoisted so that it can be shifted when it is off the ground; the shifting process involves the coordination of the two vehicles, the operation is complicated and the efficiency is low; at the same time, at the present stage, the luffing device of the super-lifting 1. When the superlift counterweight suspension pull plate and the superlift counterweight are connected, there will be a certain angle error when the superlift mast is folded back or there will be a certain error in the position of the superlift counterweight when the superlift counterweight is placed, resulting in the superlift counterweight The suspension pull plate and the installation point of the superlift counterweight are not at the same position, and the whole machine needs to be adjusted by shifting or other adjustment methods. At this time, the superlift counterweight luffing device needs an auxiliary crane to assist in the adjustment, and the installation efficiency is low; After that, after the boom or working conditions are replaced, assemble according to the above process
