Continuous rigid frame track beam

Abstract

The invention discloses a continuous rigid frame track beam, and relates to the technical field of continuous rigid frame track beams. The continuous rigid frame track beam comprises a bunching frame, a right-angle bending plate, a telescopic rod, telescopic hole boxes, a telescopic chute, a guide column, a lifting rod, a triangular rotating plate, a lifting pressing groove and a fixed pressing groove, the outer wall of the bunching frame is provided with a wrench used for driving the right-angle bending plate to vertically rotate; the section, away from the bunching frame, of the right-angle bent plate is movably connected with a telescopic hole plate used for driving the telescopic rod to stretch out and draw back horizontally, and the outer wall of the telescopic rod is fixedly connected with a telescopic spring used for driving the three sets of telescopic hole boxes distributed at equal intervals to stretch out and draw back synchronously. In the bunching frame, the wrench is rotated to drive the right-angle bent plate to rotate, so that the right-angle bent plate rotates to drive a telescopic rod to move through a telescopic hole plate, the telescopic rod moves to drive three groups of telescopic hole boxes to synchronously and oppositely move through the telescopic spring, and control operation on movement of a guide column is achieved.

Description

technical field [0001] The invention relates to the technical field of continuous rigid frame track beams, in particular to a continuous rigid frame track beam. Background technique [0002] The track beam is not only the track on which the monorail train travels, but also its load-bearing structure. At present, the general track beam structure system mainly includes simply supported system and continuous rigid frame system. In order to reduce the self-weight, the track beam of simply supported system at home and abroad is in the form of hollow section, while the continuous rigid frame system has no application engineering examples in China. , Foreign application projects all use hollow section track beams, and the variable height hollow section track beams put forward high requirements for the quality control of track beam construction. [0003] However, the existing continuous rigid frame track beam has the problem of inconvenient maintenance during use, which makes it im...
