Abstract

The invention discloses a rail fine adjustment frame. The rail fine adjustment frame comprises a main frame body and an adjustment unit installed on the main frame body. The adjustment unit comprises a height adjusting assembly which is arranged in the height direction of the main frame body and enables the main frame body to move and be locked in the vertical direction, a longitudinal adjusting assembly which is movably connected with the main frame body and can move and be fixed in the longitudinal direction of the main frame body, and a transverse adjusting assembly which is movably connected with the main frame body and can move and be fixed in the transverse direction of the main frame body. Compared with the prior art, the rail fine adjustment frame can perform fine adjustment on the height position, the transverse position and the longitudinal position of a medium-low speed maglev III-type connector, and the installation precision of the III-type connector is effectively improved.

Description

technical field [0001] The present application relates to the technical field of medium and low speed maglev track equipment, and more specifically, relates to a track fine adjustment frame. Background technique [0002] The track structure of the medium and low speed maglev system is mainly composed of a rail row, a fastener system and a rail platform. For the deformation of rail rows caused by temperature changes, expansion joints need to be set between rail rows, and the size of expansion joints reserved between rail rows should satisfy that the locked rail rows are under the control of longitudinal resistance, and there is enough space for rail rows to Release temperature stress. [0003] Expansion joints are connecting devices installed at the expansion joints between adjacent rail rows. According to the expansion and expansion of the rail joints, they can be divided into type I, type II and type III expansion joints. Type I expansion joints are mainly used between si...
