Bridge gantry crane hanging bracket and using method thereof

Abstract

The invention discloses a bridge gantry crane hanging bracket and a using method thereof. The bridge gantry crane hanging bracket comprises a gantry frame assembly for supporting, an electric hoist used for completing lifting work, a driving mechanism which is arranged at the top of the gantry frame assembly and is used for driving the electric hoist to move left and right, and a self-balancing assembly which is arranged on the surface of the electric hoist and is used for adaptively adjusting and reducing swing of a lifting hook; the lifting hook is movably arranged at the bottom of the electric hoist. One pulling rope can be pulled through shaking of the lifting hook, and the pulling rope drives a mounting plate in the position to be pulled downwards, so that two fixing boxes are not at the same height, an electric contact on the inner wall of one fixing box is completely immersed by mercury liquid, and at the moment, a current loop is formed; and the pulling rope in the lower position is controlled to pull the lifting hook, so that the shaking amplitude of the lifting hook is shortened, the lifting hook is prevented from continuously shaking towards one end, and the situation that a lifted object swings and shakes to cause damage is prevented.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge gantry crane hanger and a using method thereof. Background technique [0002] Bridges refer to buildings built for roads to cross natural or artificial obstacles. Refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations, and hoisting mechanisms are required during bridge construction. [0003] However, in the actual use of the prior art, the suspended material cannot be well fixed, and the problem of swinging during the lifting process easily causes damage to the suspended material and affects the use. Contents of the invention [0004] The object of the present invention is to provide a bridge gantry crane hanger and its use method, so as to solve the problems raised in the above-mentioned background technology. [0005] To achieve the above object, the present invention provides the following tec...
