Construction method of large displacement modular telescopic device for medium and low speed maglev track beam

Abstract

The invention discloses a construction method of a large-displacement modular extending and retracting device for medium-low-speed magnetic levitation track beams. The construction method comprises the following steps that S1, extending and retracting device supports are mounted; S2, simply supported small longitudinal beams and the extending and retracting device supports are connected and mounted; S3, longitudinal sliding grooves are formed; and S4, modular extending and retracting track panels are mounted. The large-displacement modular extending and retracting device crosses a beam seam tobe assembled together with the front track panel and the rear track panel, the specific assembly construction problem is guided to be solved, and the large-displacement modular extending and retracting device is suitable for large-displacement extending and retracting of the large-span track beams or long-coupling continuous track beams.

Description

technical field [0001] The invention belongs to the field of medium- and low-speed maglev rail transit, and in particular relates to a construction method of a large-displacement modular telescopic device for medium- and low-speed maglev rail beams. Background technique [0002] The medium and low-speed maglev rail transit adopts the suspension and guidance technology of the constant electromagnet suction type, and realizes the suspension and guidance of the vehicle through the electromagnetic attraction between the U-shaped electromagnet on the vehicle suspension frame and the F-shaped rail. At present, the middle and low speed maglev track beam structure and track structure are divided into two parts. The track structure is laid on the top of the concrete track beam. , The expansion and contraction of the track structure. [0003] At present, there are conventional slotted track joints for medium and low-speed maglev transportation (including type I, type II, and type III...
