Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The invention proposes a bridge swivel control system based on the Beidou navigation system, which is installed on the swivel bridge, and monitors the movement status of the bridge during the swivel process of the swivel bridge; according to the monitoring results, controls the swivel process Start and stop, and correct the deflection of the bridge body to avoid the overturning of the bridge body; the bridge rotation control system of the Beidou navigation system includes: Beidou signal receiver 1, control machine 2, deviation correction driver 3, deviation correction track 4, cou...

Abstract

The invention belongs to the field of bridge construction, and particularly relates to an application method of a bridge swivel control system based on a Beidou navigation system, and the control system comprises a Beidou signal receiver, a control machine and a deviation rectification driver. The application method of the control system comprises the following steps: 1) setting an early warning threshold value and a deviation rectification value of a pier deflection angle; 2) starting the control system; 3) starting to rotate; 4) monitoring the swivel progress; 5) giving an alarm; 6) reducingthe pier deflection angle; 7) stopping alarming; and 8) ending swivel. The system is used for realizing automatic monitoring, automatic deviation correction and automatic stalling in the bridge swivel construction process, so that informatization of a construction site can be embodied, and the safety supervision efficiency of the construction site is remarkably improved.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to an application method of a bridge rotation control system based on a Beidou navigation system. Background technique [0002] The swivel system of large bridges is generally divided into upper and lower parts. The upper turntable includes the upper spherical hinge and support feet, and the lower turntable includes the lower spherical hinge, ring slide, sand barrel, swivel drive system, bearing platform, etc., through the steel pin shaft. The connection positions the two parts to combine into a complete swivel system. The swivel construction of a large bridge basically rotates around a spherical hinge, and the overturning moment is balanced by the rolling support around the spherical hinge. During the actual swivel process, due to unfavorable conditions such as the influence of wind force, manufacturing errors of the spherical hinge, uneven mass stiffness of the swiv...
