Railway overhead longitudinal beam mounting and positioning auxiliary device

Abstract

The invention provides a railway overhead longitudinal beam mounting and positioning auxiliary device, which belongs to the field of railway engineering equipment and at least comprises two positioning auxiliary devices arranged on two sides of a longitudinal beam and a cross beam correspondingly, wherein the longitudinal beam and the cross beam are I-shaped steel profiles; the positioning auxiliary device comprises a positioning piece and an auxiliary fixing piece; the auxiliary fixing piece is correspondingly and fixedly clamped on the outer side of a beam plate at the upper end of the cross beam; and the positioning piece is slidably connected to the auxiliary fixing piece in the beam body direction of the cross beam, and one end of the inner side of the positioning piece is separated from or abuts against the outer side of a beam plate at the lower end of the longitudinal beam. The positioning auxiliary device is small and compact in structure and convenient to carry and install, the problem that positioning is difficult when the longitudinal beam and the cross beam are installed is solved, the manual labor intensity can be reduced, manpower resource consumption is reduced, the installation efficiency and installation precision of the longitudinal beam are improved, and interference to a railway transportation line is reduced.

Description

technical field [0001] The invention relates to the field of railway engineering equipment, in particular to an auxiliary device for installing and positioning railway overhead longitudinal beams. Background technique [0002] In the construction of the underpass railway overpass project, in the fixed installation project of I-beam longitudinal beams and beams, the beams need to be installed in parallel in place first, and the installation position of the longitudinal beams should be marked on the beams before hoisting; , Manually use crowbars with lifting equipment to position the falling beams on the longitudinal beams. This installation method has the following disadvantages: [0003] 1. The weight of a single piece of longitudinal beam is more than six tons, it is difficult to manually pry and locate, and many operators are required; [0004] 2. During the hoisting construction of the longitudinal beam, the railway traffic needs to be blocked according to the regulatio...

AI Technical Summary

Problems solved by technology

[0003] 1. The weight of a single piece of longitudinal beam is more than six tons, it is difficult to manually pry and locate, and many operators are required;

[0004] 2. During the hoisting construction of the longitudinal beam, the railway traffic needs to be blocked according to the regulations, and it is difficult to achieve a fast and accurate positioning by manual prying, and the installation process is time-consuming and labor-intensive;

[0005] 3. The installation efficiency of longitudinal beams is low, and the construction period is long, which has a great impact on the transportation along the railway
