A linear positioning device for f-shaped rail row

Abstract

The invention discloses a line type positioning device of an F-shaped track panel, comprising a support frame, a positioning component arranged at one side above the support frame as well as a rotational positioning component arranged at the other side above the support frame. According to the invention, by arranging the positioning component and the rotational positioning component, line types of all points on an F-shaped track can be quickly and effectively pre-positioned according to the designed line type of the F-shaped track panel; meanwhile, displacement components are arranged in the positioning component and the rotational positioning component to obtain certain adjustment quantity so as to be convenient for carrying out secondary positioning on the F-shaped track, thereby meeting the batch assembly precision of F-shaped track panels of various line types; and the disassembly and assembly speeds of the F-shaped track panel on the positioning device are increased through the rotational positioning component. The positioning device disclosed by the invention can realize assembly of F-shaped track panels of the same line type only by pre-positioning once so as to be repeatedly applied to line type adjustment construction of multiple F-shaped track panels of the same type; and the adjustment is quick, the operation is simple, construction steps are simplified, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of assembling a magnetic levitation rail row, in particular to a linear positioning device for an F-shaped rail row. Background technique [0002] Maglev transportation is a brand-new transportation mode different from traditional railways, highways, and aviation. It has a series of characteristics such as low noise, small vibration, no pollution, strong line adaptability, and easy implementation. It is safe, reliable, and environmentally friendly. A new type of urban rail transit system, many cities in China have studied the use of low-speed maglev transportation technology to solve urban traffic problems. The rail row of medium and low-speed maglev trains is usually an F-shaped rail row, which is formed by connecting two F-shaped rails with bolts through sleepers, and then the F-shaped rail row is installed and fixed on the bridge rail platform through a fastener set. [0003] The medium and low-speed mag...

Problems solved by technology

However, there is currently no special tool that can assist in the positioning and adjustment of the F-shaped rail. Workers often set out and mark the line on the spot, and then fit the F-shaped rail to the lofted curve and first temporarily fix it and then assemble it with the sleeper. If the F-shaped rail row is assembled If there is a deviation in the center, it can only be adjusted by hammering or jacking horizontally. The work is cumbersome, inefficient, and the effect is not good. It is difficult for the plane axis position and level deviation of the two F-shaped rails to reach the design Require
