A double-block ballastless track bridge base transverse formwork positioning device

Abstract

The invention discloses a double-block type ballastless track bridge base transverse template positioning device that comprises a bridge base, a trapezoidal transverse template and a fixing device; the fixing device comprises a parallel fixing mechanism and a movable pressing mechanism, wherein the movable pressing mechanism is installed on the parallel fixing mechanism, and the movable pressing mechanism comprises a parallel pressing mechanism and a self-adaptive moving mechanism; the positioning device relates to the ballastless track field. According to the double-block type ballastless track bridge base transverse template positioning device, the fixing device convenient to fit and combine can be designed according to the shape and the installation mode of the transverse template; themoving trend of automatic sedimentation of the movable pressing mechanism on the fixing device is utilized to enhance the relevance of each template and the fixing device, so that the problems that the positioning device used by a common transverse template is difficult to associate with a plurality of transverse templates are solved; and when concrete is poured, the time difference of a deviationtrend of the transverse templates easily affects the concrete pouring efficiency can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of ballastless track, in particular to a double-block type ballastless track bridge base transverse template positioning device. Background technique [0002] The horizontal formwork is an important part of the double-block ballastless track. In the existing technology, when installing the horizontal formwork, it is mainly fixed by square wood or wooden wedges, but this method will cause flow when pouring concrete In order to avoid the occurrence of deviation, in the existing technology, a separate positioning device is provided. This device is similar to a fixture, which fixes two adjacent horizontal templates in parallel at a certain distance, but we all It is known that when concrete is poured on ballastless track, it is mainly poured by punching holes. There is a time difference when the concrete flows on the base, especially in summer. The deviation trend of the horizontal formwork occurs in different ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a double-block type ballastless track bridge base transverse formwork positioning device, which solves the problem that the positioning device used in the general transverse formwork is difficult to associate multiple transverse formworks, and the transverse formwork runs away when pouring concrete. The time difference of partial trend is easy to affect the efficiency of pouring concrete
