GNSS double-moving-station building construction tower crane

Abstract

The invention discloses a GNSS double-moving-station building construction tower crane. The GNSS double-moving-station building construction tower crane comprises a cross arm, a first lifting rope segment, a second lifting rope segment, a movable pulley located between the first lifting rope segment and the second lifting rope segment, and a lifting hook at the tail end of the second lifting rope segment. The tower crane is matched with an auxiliary system comprising a reference station and a monitoring device. The tower crane comprises a first moving station installed at the position, over the lifting hook, on the cross arm, and a second moving station arranged on the movable pulley; the first moving station and the second moving station receive signals from the reference station, acquire the position information of themselves and send the position information to the monitoring device, whether the difference between the plane position of the first moving station and the plane position of the second moving station is large or not is determined, if the difference is large, it is considered that the first moving station, the second moving station and the lifting hook are on the same straight line, and the position of the lifting hook is determined according to the position of the first moving station and the position of the second moving station; and if the difference is not large, the plane position of the second moving station is determined as the plane position of the lifting hook, and the elevation of the lifting hook is determined according to the length of the second lifting rope segment 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 using GNSS technology. Background technique [0002] The hoisting operation of the building construction tower crane needs to determine the position of the hook. At present, manual guarding is mostly used. The disadvantages of this manual on-duty method are obvious: the observation is not accurate enough, the requirements for the operator are high, and it may cause harm to the on-duty personnel on the ground. In addition, the method of directly installing GPS on the hook is prone to collisions, and in some cases, the GPS installed on the hook cannot provide valid data, etc., so it also needs to be improved. Contents of the invention [0003] In view of the above circumstances, the present invention proposes to alleviate or eliminate one or more disadvantages in the prior art, and at least provide a beneficial option. [0004] To achie...
