Tower crane rotation anti-collision device and using method

Abstract

The invention provides a tower crane rotation anti-collision device which comprises a collision unit and a buffer unit. The buffer unit is arranged on a first support, the collision unit is arranged on a second support, and the first support and the second support can rotate relatively. The buffer unit comprises springs, the collision unit comprises a limit switch, the limit switch is used for cutting off a power supply of a tower crane after the collision unit collides with the buffer unit, and the springs buffer inertia force of rotation of the tower crane through compression. According to the anti-collision device, the limit switch is used as the last mechanism to cut off the power supply of the tower crane, the inertia force of the tower crane can be buffered through the springs, slow braking of the tower crane can be achieved through compression of the springs, in other words, collision between a suspension arm of the tower crane and surrounding obstacles is avoided, and safety accidents are effectively eradicated. The invention further provides a using method of the tower crane rotation anti-collision device.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a tower crane rotation anti-collision device and a use method. Background technique [0002] Tower crane is a kind of large-scale lifting equipment that can do vertical movement, horizontal movement and rotary movement. It can lift objects to the required position within a certain range. It has played an obvious role in reducing the labor intensity of construction personnel, speeding up the progress of the project, and improving work efficiency. [0003] During the hoisting process of the tower crane, due to the limitation of the surrounding environment, or the limitation of multi-tower operation, the tower crane can only make a rotary motion within a certain angle range, otherwise the tower crane will collide with the surrounding buildings or other tower cranes. . The electrical limit of the tower crane itself can cut off the power supply when the tower crane is about to ...
