A system and method for dynamic monitoring and adjustment of straddle track beam alignment

Abstract

The invention discloses a dynamic monitoring and adjusting system and method for straddling track beam alignment, which includes track beam alignment adjustment devices arranged at both ends of the track beam, and is characterized in that it also includes: a mobile target, a mobile total station, a mobile Terminal, alarm device; the mobile target includes a target mobile vehicle that can slide along the rail beam line, and a laser target arranged on the target mobile vehicle; the mobile total station includes a total station that can slide along the center line of the rail beam Mobile car, the gyroscope total station that is arranged on the total station mobile car; Described mobile terminal comprises data processing module, base mobile control module, human-computer interaction interface; Described alarm device comprises alarm module, is connected with alarm module siren. The present invention can save a lot of work of manually lifting beams for measurement, and greatly improves the efficiency of track beam line shape measurement; at the same time, it can save the operation of repeatedly setting or disassembling prisms and laser targets on different track beams, and avoids the need for workers to work on the track The high-altitude operation on the beam improves the safety of construction.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit straddle-type track beam construction, in particular to a dynamic monitoring and adjusting system and method for straddle-type track beam alignment. Background technique [0002] The straddle-type monorail transportation system is a new type of traffic system in which vehicles ride directly on the track beams, and the section generally adopts a viaduct span structure. The track beam generally adopts a prefabricated prestressed concrete simply supported structure with a standard section. The load-bearing wheels of the vehicle run directly on the upper surface of the track beam, and the guide wheels and stabilizing wheels surround the track beam from both sides. The track beam is not only a load-bearing structure, but also a running vehicle. The track requires high prefabrication precision and erection precision to ensure the safety and comfort of driving. In the prior art, a Chinese pat...

AI Technical Summary

Problems solved by technology

In conventional construction, the traditional total station is generally used to stake out the track beam for linear measurement, but this method has the following three disadvantages: 1. The support of the total station generally uses a tripod, and the tripod is fixed by opening its own legs. The beam is narrow and high, and the outriggers of the triangle bracket cannot be opened normally like on flat ground, so it is difficult to meet the requirements when the bracket is erected on the track beam

2. Since the viaduct bridge span structure is used, if the total station is placed on the ground and the prism is placed on the center line of the track beam, and the measurement is performed from bottom to top, the total station cannot fully see the position of the prism, and the track beam will be Accuracy affects

3. The upper part of the track beam belongs to the high-altitude operation, and the safety hazards of the surveyors are relatively large during the operation
