Position Detection and Judgment Method and Control Device of Bridge Inspection Car's Straight-line Swing Track

Abstract

The invention discloses a position detection and judgment method and a control device for linear and rotary rail change of a bridge inspection vehicle, and belongs to the technical field of bridge inspection vehicles. According to the invention, a direction controller is connected to a controller; a left detector and a right detector are respectively arranged on a left rotation driving device and a right rotation driving device and are respectivelyconnected to the controller; the left and right detectors detect the rotation angles of the rotation driving devices and transmit position signals to the controller; the controller receives operating mode signals and the position signals, performs logic operation and judgment, and sends control signals to left and right travelling mechanisms to make the advancement of the left and right travelling mechanisms consistent, or sends an alarm signal to an error alarm to stop operation; the left and right travelling mechanisms are respectivelyconnected to the controller and are controlled by the controller; and the error alarm is connected to the controller and sends the alarm. The method and the control device solve the problem that theoperation of the rotation driving devices at two ends is not consistent when faulty operation occurs in the process of travelling and changing rails of the bridge inspection vehicle.

Description

technical field [0001] The invention relates to the detection and control technology of the motion direction and position of the straight-line rotary transition track of various steel box girder outer bridge inspection vehicles, in particular to a position detection and determination method and control device of the straight-line rotary transition track of bridge inspection vehicles. Background technique [0002] During inspection of the steel box girder outer bridge of the cross-river (river) bridge, double-track operation (straight line) is required. When passing the pier, it is necessary to change the walking direction (change track), oblique line (single track) and vertical walking to bypass the pier and run to another span. (side). [0003] Regular inspection and maintenance on the outside of the steel girder. The usual solution is: double-track operation (straight line) during the inspection and inspection of the outer bridge of the steel box girder. (Side) During reg...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to: aim at the above-mentioned problems, to provide a method and control device for detecting and determining the position of the straight-line rotary rail of the bridge inspection vehicle with convenient operation, high precision, simple structure and good reliability, which solves the problem of bridge inspection vehicles. In the process of walking and track changing, avoid the problem of inconsistent operation of the drive and slewing devices on both sides caused by wrong operations during operation. It can be widely used in the detection and determination of the direction position of the left and right walking mechanisms in the operation of various steel box girder outer bridges. methods and control techniques
