Problems solved by technology

[0003] For the tower crane boom under the prior art, on the one hand, when it is built, the tower crane needs to be built and installed as a whole. Because the arm body is huge, it is very troublesome to build it; In the actual construction situation, the arm body is usually built as a whole, and the length is fixed. It cannot be adjusted according to the actual needs of the site, and thus cannot meet the actual construction needs. For this reason, the present invention proposes a telescopic construction tower boom to solve the above problems

Abstract

The invention discloses a telescopic construction tower crane arm. An arm body main body and a telescopic arm are movably arranged, and a first telescopic rod and a second telescopic rod are arranged,so that a telescopic function of the construction tower crane arm can be achieved, the length of the crane arm can be adjusted in a telescopic manner, and when a tower arm of a construction tower isconstructed and erected, compared with the prior art, the construction tower crane arm is more convenient to build and construct; the construction tower crane arm can be adjusted according to a site construction situation, so that the construction efficiency is improved; a first reinforcing rod, a second reinforcing rod and a reinforced fixing mechanism are connected to a supporting rod, the structural strength of an arm body can be guaranteed when the crane arm is telescopically adjusted, the strength quality of the crane arm is ensured, meanwhile, the crane arm can be telescopically adjusted, and the use quality of the crane arm and the engineering construction quality of the crane arm are ensured.

Description

technical field [0001] The invention relates to the technical field of building construction towers, in particular to a retractable construction tower boom. Background technique [0002] Tower crane (tower crane) is referred to as tower crane, also known as tower crane, which originated in Western Europe; a rotating crane with a boom mounted on the upper part of a high tower; a large working space, mainly used for vertical and horizontal transportation of materials in building construction and construction The installation of components; it consists of three parts: metal structure, working mechanism and electrical system; the metal structure includes tower body, boom and base; the working mechanism includes four parts: lifting, luffing, turning and walking; the electrical system includes motor, control Devices, power distribution cabinets, connecting lines, signals and lighting devices, etc.; tower cranes are the preferred lifting and transportation equipment for high-rise a...
