An "f" type guide rail fine adjustment frame for medium and low speed maglev track

Abstract

The invention discloses an "F" type guide rail fine adjustment frame for medium and low speed maglev tracks, which includes a frame body, a prism installed on the frame body, and is used for clamping the frame body and the "F" type guide rail to be measured. The device and the locking device used to lock the frame body and the measured "F" type guide rail, the frame body includes the main board, the vertical plate fixedly installed on one side of the main board and the prism mounting frame installed on the top of the vertical plate for prism installation, the lock The clamping device includes a permanent magnetic chuck installed on the main board and a clamping mechanism for fixing the permanent magnetic chuck on the main board. The magnetic surface of the permanent magnetic chuck acts on the standard surface under the induction plate of the measured "F" type guide rail. The invention can achieve the purpose of leading the lower standard surface of the induction plate to the standard surface of the induction plate, solves the problem that the accuracy of the standard surface under the induction plate of the “F” track cannot be directly measured, and is suitable for the fine adjustment construction requirements of the medium and low speed maglev track , it is convenient to adjust the elevation, mileage and centerline of the rail row of the medium and low speed maglev track.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment for medium and low speed maglev tracks, and in particular relates to an "F" type guide rail fine adjustment frame for medium and low speed maglev tracks. Background technique [0002] The Beijing medium-low speed maglev traffic demonstration line (S1 line) is the first medium-low speed maglev traffic line independently developed by my country. The medium and low-speed maglev track is different from the wheel-rail structure. The wheel-rail is made of two steel rails as the rail row, and the rail row and the supporting fasteners cooperate to form a wheel-rail structure; the medium-low speed maglev track is composed of two "F" type guide rails and laid on the The steel sleepers between the two "F" type guide rails form the rail row, and then the magnetic levitation rail row and the supporting fasteners cooperate to form the magnetic levitation track structure. It is necessary to adjust t...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an "F" type guide rail fine adjustment frame for medium and low speed maglev rails, which can lead the lower standard surface of the induction plate to the standard surface on the induction plate. The purpose of this surface solves the problem that the accuracy of the standard surface under the "F" track induction plate cannot be directly measured. It is suitable for the fine adjustment construction requirements of the medium and low speed maglev track, and is convenient for adjusting the elevation, mileage and track row of the medium and low speed maglev track. The center line can effectively speed up the laying speed of the rail row and improve economic benefits, and has broad application value in the construction of medium and low speed maglev rail transit
