Anti-collision device of crane for building construction

Abstract

The invention discloses an anti-collision device of a crane for building construction, relates to the technical field of crane anti-collision equipment. The problems that a fixed anti-collision structure is difficult to disassemble and replace, the later use is quite inconvenient, and the protection effect is poor are solved. The device comprises a supporting frame, and a protective sleeve mounting plate capable of sliding up and down is movably arranged on the outer side of a pull rope. According to the device, dismounting convenience can be increased through pre-fixing plates, the two pre-fixing plates are fixedly and symmetrically arranged at the front corner of the supporting frame through bolts before the crane is in use, and then a square plate at the bottom of an air bag support plate can be pushed from top to bottom to be embedded into an empty groove among the pre-fixing plates, a side clamping plate and a front clamping plate; and when the top of the front end of a telescopicframe collides, an air bag at the top of the air bag support plate firstly makes contact with external hard objects to play a preliminary buffering role, the air bag support plate can be forcefully pulled out upwards, the pre-fixing plates can be fixedly installed all the time, and therefore the replacement is more convenient in the later period.

Description

technical field [0001] The invention relates to the technical field of crane anti-collision equipment, in particular to an anti-collision device for a construction crane. Background technique [0002] Crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of crane is the unified title of lifting machinery. It is usually called crane, mainly car crane, crawler crane and tire crane. The usefulness of crane In hoisting equipment, rescue, lifting, machinery and rescue. [0003] For example, the patent application number 201821752755.7 discloses an anti-collision device for a construction crane, which relates to the technical field of anti-collision equipment for civil engineering bridge construction cranes, and is specifically an anti-collision device for a construction crane, including a rotating shaft and a rotating shaft A support is movably connected to the upper surface of the support...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of anti-collision device of the crane used in building construction, to solve the problem that the existing anti-collision devices on the crane support frame proposed in the above-mentioned background technology are all fixed structures. The structure is easily damaged, and the fixed structure is difficult to disassemble and replace. It is very inconvenient to use later, and the position of the hook is also equipped with an anti-collision structure. It cannot be disassembled, and the hook is still easy to collide with other parts, and the protection effect is poor
