Building construction tower crane and fixed-point hoisting and lofting auxiliary system thereof

Abstract

The invention discloses a building construction tower crane and a fixed-point hoisting and lofting auxiliary system thereof. The building construction tower crane comprises a cross arm, a lifting rope and a lifting hook and is matched with the fixed-point hoisting and lofting auxiliary system. The fixed-point hoisting and lofting auxiliary system comprises a base station, a monitoring device and a client terminal. The building construction tower crane is characterized by further comprising a moving station and a speedometer, wherein the moving station is mounted on the cross arm and right above the lifting hook; the speedometer is used for detecting the mileage of the lifting rope; and the moving station receives a satellite difference correction signal from a base station, acquires position information of the moving station and sends the position information to the monitoring device, the speedometer acquires the mileage of the lifting rope, and the monitoring device determines the position of the lifting hook according to the mileage of the lifting rope and the position information of the moving station. According to the technical scheme of the invention, process links in a manual attendance method can be reduced, and the intuition, convenience, accuracy and efficiency of the hoisting operation can be improved.

Description

technical field [0001] The invention relates to a tower crane for building construction and an auxiliary system for hoisting and fixed-point setting-out, which assists the tower crane in precisely fixing and setting-out. Background technique [0002] At present, during the hoisting operation of the building construction tower crane, the position of the hook is determined to be manually guarded. For example, a tower crane is disclosed in ZL200620036492.0. Such as figure 1 As shown, in the tower crane, the operator utilizes the reflector 19 on the seat to observe the working condition of the suspended object. In other tower cranes of the prior art, there is also the use of setting a red flag on the boom for observation. Such observations are not accurate enough and require high requirements for operators. In addition, the tower cranes in the prior art also require the operator and the hoist to establish a unified relationship and cooperate closely to complete the hoisting ...

AI Technical Summary

Problems solved by technology

This kind of observation is not accurate enough, and the requirements for operators are high

In addition, the tower cranes in the prior art also require the operator and the hoist to establish a unified relationship and cooperate closely to complete the hoisting task. The control process is complicated and the quality of the personnel is strictly required.

Using the traditional manual on-duty method to command the hoisting task, the operation efficiency is low and it is easy to be restricted by the visibility conditions, making the operation difficult, time-consuming, labor-intensive, low in intelligence and uneconomical
