Intelligent unmanned tower crane jacking device

Abstract

The invention belongs to the field of tower cranes, and particularly relates to an intelligent unmanned tower crane jacking device which comprises a jacking sleeve, an outer sleeve, an inner rod, a reset spring, a guide wheel, a guide sleeve, a limiting rod, a tower body section frame, a clamping block A, a jacking mechanism and an electric push rod. Wherein the top sleeve is nested outside a plurality of tower body section frames which are sequentially stacked and connected together through high-strength bolts, two layers of outer sleeves are mounted on the inner side of the top sleeve, and eight symmetrical outer sleeves are arranged in each layer; the transmission connection cooperation between the telescopic structures where any two opposite guide wheels are located can effectively prevent the rotary base from shaking relative to the tower body section frame in the lifting process due to the fact that the balance arm and the cargo boom are unbalanced. The transmission connection cooperation between the telescopic structures where any two opposite guide wheels are located ensures that the tower body section frame with the inaccurate or deformed appearance cannot be stuck with the guide wheels in the jacking process.

Description

technical field [0001] The invention belongs to the field of tower cranes, in particular to an intelligent unmanned tower crane jacking device. Background technique [0002] Tower cranes are the most commonly used lifting equipment on construction sites, also known as "tower cranes". , concrete, steel pipes and other construction raw materials. The tower crane is an indispensable equipment on the construction site. [0003] Before the tower crane is used, it is necessary to adjust the balance of the tower by adjusting the position of the hoisting trolley, and then perform the lifting and heightening operation of the tower, and the operation of adjusting the balance is cumbersome and inefficient. Before jacking up, it is necessary to adjust the distance between the guide wheel on the top sleeve and the section frame to an appropriate distance, otherwise it is easy to cause the guide wheel and the section frame bracket to get stuck due to inaccurate production shape or defor...

AI Technical Summary

Problems solved by technology

[0003] Before using the tower crane, it is necessary to adjust the balance of the tower by adjusting the position of the lifting trolley before lifting and heightening the tower, but the operation of adjusting the balance is cumbersome and inefficient

Before jacking up, it is necessary to adjust the distance between the guide wheel on the top sleeve and the joint frame to an appropriate distance, otherwise it is very easy to get stuck between the guide wheel and the joint frame bracket due to the inaccurate shape or deformation of the joint frame during jacking. The gap between the guide wheel and the joint frame may cause the tower body to shake due to improper adjustment and balance during the jacking process.

[0004] The traditional adjustment of the balance and the adjustment of the gap between the guide wheel and the joint frame requires workers to strictly install and operate the procedures, which is inefficient
