Tower crane standard knot perpendicularity detection device and method

Abstract

The invention discloses a tower crane standard knot perpendicularity detection device and method. The device is mounted on a tower body of the tower crane; the tower body comprises standard knots composed of a plurality of steel beams. The standard knots are connected through bolts; the detection device comprises a shell, and a tension sensor, a power supply module, a main control module and a wireless module that are installed in the shell. The tension sensor comprises a strain gauge and two strain blocks. The two strain blocks are symmetrically installed on the two sides of the strain gaugealong the central axis of the strain gauge; one end of each strain block is connected with one end of the strain gauge, the other end of each strain block penetrates out of the shell and is connectedwith a spring, each spring is connected with a hook, and the two hooks are hung on horizontal steel beams of the adjacent standard knots respectively, so that the two springs are vertical and are in astretched state; the strain gauge is connected with the main control module, and the main control module is connected with background equipment through the wireless module. The tower crane standard knot perpendicularity detection device is simple in structure and convenient to install, the tower crane inclination can be monitored for 24 hours, and the safety performance of the tower crane is improved.

Description

technical field [0001] The invention relates to the field of tower crane equipment, in particular to a device and method for detecting the verticality of a standard section of a tower crane. Background technique [0002] Tower cranes are frequently used in the construction industry. The tower crane mainly includes a vertical tower body, a horizontal boom and a horizontal wall. The tower is tall and includes several standard sections connected in turn by screws. The boom is long, and the boom is more than the balance arm. Long, the boom bears a lot of pressure when transporting building materials. The safety accidents caused by the collapse of tower cranes are increasing year by year. The main reasons are as follows: 1. The tower body of the tower crane is deformed due to excessive hoisting weight and poor operation; It is weakened, and then a large degree of jitter occurs during the lifting process, which causes the stress point of the standard section to be concentrated, t...

Problems solved by technology

The safety accidents caused by the collapse of the tower crane are increasing year by year. The main reasons are as follows: 1. The tower body of the tower crane is deformed due to excessive lifting weight and poor operation; 2. The screw fixing the standard section is loose, and the connection performance between the standard sections It is weakened, and then a large degree of shaking occurs during the lifting process, which leads to the concentration of the stress point of the standard joint, thereby increasing the pressure of the contact point and exceeding the maximum value of the force, which directly leads to serious deformation of the standard joint and then leads to collapse; 3. Used in tower cranes During the process, maintenance personnel cannot realize effective real-time monitoring and lack the ability to actually understand the current operating status of the tower crane. It is difficult to meet the safety protection requirements of some high-intensity operation tower cranes by relying on regular inspections or regular maintenance, and even further professional maintenance The cost of personnel and inspection equipment is relatively high, which leads to an increase in the cost of construction enterprises
