Turnover device and method suitable for elastic deflection beam

Abstract

The invention relates to a turnover device and method suitable for an elastic deflection beam. The turnover device and method suitable for the elastic deflection beam can enable a track beam not to deform and not to yield when the track beam which is small in rigidity and easy to deform is turned over, the turnover device is composed of an L-shaped turnover frame, supporting piers, an anchoring pin shaft lug, an anchoring pin shaft and a fixed base, and the anchoring pin shaft lug is connected with the root of the L-shaped turnover frame; and the anchoring pin shaft lug is hinged to the fixed base through the anchoring pin shaft, the fixed base is fixed to the ground to serve as a fixed rotation point, and the supporting piers are connected with a frame body of the L-shaped turnover frame. The turnover device and method have the advantages that firstly, stable turnover of the elastic deflection beam is achieved, the supporting piers are arranged to support a beam body, and cantilever parts at the two sides of the beam body are protected; secondly, the rigidity of the beam body in the turnover process is improved by arranging a plurality of lifting turnover points, and the size of the beam body is easy to control; and thirdly, the turnover problem of an overweight beam body is solved, and the turnover of a large-tonnage beam body can be realized by virtue of lifting equipment with smaller tonnage by virtue of a lever principle through the arrangement of the ground anchor type fixed base.

Description

technical field [0001] The invention relates to a turning device and method suitable for an elastic flexural beam, which can turn a track beam with low rigidity and easy deformation during turning operation without deformation and yielding of the track beam, belonging to a track beam. Turn over device manufacturing field. Background technique [0002] In the assembly and welding of steel track beams, the beam body can only be assembled and welded after several times of turning over due to structural constraints. During the turning operation of the steel track beam, due to the high rigidity of the track beam, it is only necessary to set the lifting lug device on the track beam, and the lifting lug can be suspended by the lifting equipment to realize the turning of the track beam. However, for some tracks with low rigidity and easy deformation For the beam, the lifting lug device is set on the beam. When lifting, the beam body deforms under the influence of its own weight, an...

Problems solved by technology

During the turnover operation of the steel track beam, due to the high rigidity of the track beam, it is only necessary to install the lifting lug device on the track beam, and the track beam can be turned over by hanging the lifting lug through the lifting equipment. However, for some tracks with small self-rigidity and easy deformation The beam is equipped with a lifting lug device. When it is hoisted, the beam body will deform under the influence of its own weight, or even yield.
