Device and method for high-altitude self-disassembly of tower crane arm lever

Abstract

The invention discloses a device and method for high-altitude self-disassembly of a tower crane arm lever. The device comprises a handle stem mechanism, an anti-disengagement mechanism, a lifting mechanism and a tackle mechanism, wherein the handle stem mechanism is installed at the front end of an upper chord member of a non-disassembled arm section, the anti-disengagement mechanism is connectedbetween a to-be-disassembled arm section and a lower chord member of the non-disassembled arm section and used for providing a rotary connection joint for the to-be-disassembled arm section, the lifting mechanism is formed by connecting a winch with a lifting rope, the lifting rope is bound to the to-be-disassembled arm section after being wound around the handle stem mechanism and is used for putting down the to-be-disassembled arm section, the tackle mechanism is hung on the upper chord member of the non-disassembled arm section, and a hook of the tackle mechanism hooks up the to-be-disassembled arm section. By means of the device and method, the self-disassembly of the tower crane arm lever can be realized, the disassembly process is little affected by the environment, a foundation is provided for the overall disassembly of a tower crane in a narrow space, the construction difficulty is low, control is easy, and safety is high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and method for high-altitude self-disintegration of a tower boom. Background technique [0002] Tower crane, also known as "tower crane", is the most commonly used lifting equipment on construction sites. It is used to lift steel bars, Raw materials for construction such as wood flute, concrete, steel pipe, etc. The tower crane mainly includes structures such as cap, tower body, balance arm, lifting arm, tie rod, luffing trolley, slewing tower body and cab. [0003] After the tower crane is finished, it needs to be dismantled. The traditional dismantling method is to lower the tower first, remove the standard section, then remove the balance weight and hook, then remove the lifting arm and balance arm through the ground truck crane, and finally remove the tower cap, slewing tower body, cab, upper and lower turntables, etc. However, this dismantling metho...

AI Technical Summary

Problems solved by technology

However, this dismantling method cannot be constructed in a narrow space, because in a narrow space, if the boom of the tower crane is not dismantled first, the boom cannot be lowered, and operations such as lowering the tower cannot be performed.

Therefore, in a narrow space, it is necessary to directly disassemble the tower boom at high altitude, but currently on the market, no corresponding device and method have been developed to solve the technical problems of dismantling the high-altitude tower boom
