Double-hanging rope section building construction tower crane utilizing GNSS technology

Abstract

The invention discloses a double-hanging rope section building construction tower crane utilizing a GNSS technology. The double-hanging rope section building construction tower crane comprises a tower arm, a first hanging rope section, a second hanging rope section, a movable pulley positioned between the first hanging rope section and the second hanging rope section, and a lifting hook at the tail end of the second hanging rope section, and further comprises a first moving station in the position, right above the lifting hook, on the tower arm, and a second moving station arranged on the movable pulley, wherein the tower crane is matched with a hoisting fixed-point lofting auxiliary system comprising a datum station, a monitoring device and a client terminal; the first moving station and the second moving station receive satellite differential correction signals from the datum station, acquire the self location information, and send the location information to the monitoring device; the monitoring device determines whether the planimetric positions of the first moving station and the second moving station have relatively large difference or not; if the difference is relatively large, the monitoring device reminds to temporarily slow operation; if the difference is not large, the planimetric position of the second moving station is determined as the planimetric position of the lifting hook; and the elevation of the lifting hook is determined according to the length of the second hanging rope section and the elevation of the second moving station.

Description

technical field [0001] The invention relates to a building construction tower crane, in particular to a building construction tower crane with double suspension rope sections. 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 task. The control process is complicated and ...

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
