Anti-falling beam telescopic device for straddle-type monorail transportation track beams

Abstract

The invention provides an anti-falling beam telescopic device for straddle-type monorail transportation track beams. The device comprises embedded parts and telescopic device bodies (2), the embedded parts are buried on the side surface and the end surface of track beams (5), and multiple rows of mounting holes (3) are formed in one end of each telescopic device body (2); a plurality of anti-falling teeth (4) are arranged at the other end of each telescopic device body (2), bolts penetrate through the mounting holes (3) and are connected with the embedded parts, and the telescopic device bodies (2) are tightly locked on the track beams (5) through the bolts; the anti-falling teeth (4) comprises tooth roots (401) and tooth tops (402), each tooth top (402) is fixedly arranged at one end of the corresponding tooth root (401), and the widths of the tooth roots (401) are smaller than the widths of the tooth tops (402); gaps between two adjacent tooth tops (402) are larger than the widths of the tooth roots (401) and smaller than the widths of the tooth tops (402). The anti-falling beam telescopic device has the advantages that the device is simple in structure, is mounted in an inserted mode conveniently, can effectively bear the applied force transmitted by the track beams, and has great anti-falling effect on the track beams at the same time.

Description

technical field [0001] The invention relates to the technical field of monorail rail transit, in particular to a straddle-type monorail rail rail beam anti-drop telescopic device. Background technique [0002] The relatively new light rail line in Chongqing is one of the ten key projects of my country's western development, with a total length of more than 17 kilometers. There are 18 stations, two main substations, one depot and one control center along the way. The project is designed with a straddle-type monorail transportation system, and its line conditions are as follows: the maximum design speed is 80Km / h, the minimum horizontal curve radius R=100m, the minimum vertical curve radius R=1000m, and the maximum longitudinal slope is 6%. In the line, PC track beams are used for spans of 9 to 24 meters, steel box girders are used for turnout beams, cast-in-place inverted T beams are used for long-span beams, and RC cast-in-place beams are used for beams smaller than 9 meter...

AI Technical Summary

Problems solved by technology

Therefore, the PC track beam must not only consider its stress situation, but also consider the telescopic load-bearing and anti-fall beam functions. The existing PC track beam installation process does not use anti-falling devices or equipment, so that it is installed at a position relative to the lower part. There is a potential safety hazard that the track beam body (lower track beam) will fall off
