Problems solved by technology

Although regular inspection of the tower crane is a method to eliminate potential safety hazards, the structure of the tower crane is huge, and a comprehensive inspection is a time-consuming and laborious task. At present, there is no method to automatically detect the damage position of the steel structure of the tower body

Embodiment Construction

[0010] Technical scheme of the present invention is as follows:

[0011] A method for judging the damage orientation of the tower crane tower body steel structure, the method is as follows:

[0012] 1) Install the inclination measuring device on any main limb of the slewing tower body of the tower crane or on a structure that requires parallelism with the axis line of the tower body;

[0013] 2) Use the inclination measuring device to measure in real time the inclination angle at the top of the center line of the tower body when the balance arm is respectively pressed on the four main limbs when the tower crane rotates without load:

[0014] When the balance arm of the tower crane is pressed against the main leg 3, the inclination angle at the top of the centerline of the tower body is (θ 3x , θ 3y );

[0015] When the balance arm of the tower crane is pressed against the main leg 4, the inclination angle at the top of the center line of the tower body is (θ 4x , θ 4y ); ...

Abstract

A method for judging damage position on steel structure of tower body of tower crane belongs to the technical field of tower type lifting appliance detection. The method comprises collecting top inclination of central line of tower body and establishing a characteristic model for top inclination of central line of tower body when the tower body does a revolution in idle load under intact condition. The method for judging whether the steel structure of the tower body is damaged comprises: when the measured top inclination of central line of tower body exceeds the characteristic model, judging that the position representing main limb under the suspension arm is damaged. The method for judging damage position on steel structure of tower crane provided by the invention is simple and feasible, can effectively shorten the present procedure for complete overhaul of the tower crane and improve the efficiency and is convenient for diagnosis.

Description

technical field [0001] The invention relates to a method for judging the damage orientation of a tower crane tower body steel structure, and belongs to the technical field of tower lifting equipment detection. Background technique [0002] Tower crane (tower crane) is one of the important construction machinery used in modern industry and civil engineering, because of its high working efficiency, wide range of application, large turning radius, high lifting height and simple operation, The number of uses is increasing. Due to the large structure of the tower crane, the harsh working environment and heavy load, it is easy to cause safety hazards such as loosening of the connecting bolts and damage to key welds on the tower body. If the existing safety hazards are not eliminated in time, serious consequences will often result. [0003] Chinese patent CN101183000 a visual inclination measuring method and its device, Chinese patent CN201177499 inclination measuring device, Chin...
