A method for active safety operation of tower crane group

Abstract

The invention relates to an active safe operation method for a tower crane group. The active safe operation method comprises the following steps: setting conditions for an equal-altitude tower crane, an unequal-altitude tower crane, a high-altitude tower crane tower arm, a low-altitude tower crane drawbar and a movable arm tower crane to safely pass through a crossover area of the tower crane group according to operation characteristics of the tower crane group; taking the condition for the tower cranes to safely pass through the crossover area as a restraint, establishing a repulsive force potential field model and a gravity potential field model for active safe operation of the tower crane group; calculating negative gradient of the potential field models so as to obtain potential field gravity and potential field repulsive force of the tower cranes, decomposing and then synthesizing the potential field gravity and the potential field repulsive force of the tower cranes in an amplitude-varying direction, a revolving direction and a lifting direction of the tower cranes, thereby obtaining resultant force, in the amplitude-varying direction, the revolving direction and the lifting direction, of the tower cranes so as to carry out an active safe operation decision of the tower cranes. The active safe operation method has the beneficial effects that: the potential field gravity and the potential field repulsive force are changed according to relative positions of the tower cranes, so that movement directions of lifting, amplitude-varying and revolving mechanisms of the tower cranes are changed, and therefore, active safe operation of the tower cranes is realized, and operation efficiency of the tower crane group is improved.

Description

technical field [0001] The invention belongs to the field of tower crane safety control and relates to an active safety operation method for a tower crane group. Background technique [0002] Tower cranes are one of the most commonly used construction machinery in modern engineering construction. In order to speed up the construction progress and eliminate the blind spots in lifting, the layout density of tower cranes is increasing, which greatly increases the possibility of collisions between tower cranes during operation. sex. At present, there are some anti-collision products between tower cranes in the market: such as the AC30 system of SMIE Company in France, the ATC-10 system of WECON Company in South Korea, the TAC3000 system of E-Build Company in Singapore, and the CXT / 800 tower crane group anti-collision system, Xi'an Zhimin measurement and control company's ZM-ACS30 tower crane group cross-operation protection intelligent measurement and control system. Most of ...
