Track changing control system for inspection vehicle and control method

Abstract

The invention discloses a track changing control system for an inspection vehicle and a control method, which are mainly used for controlling track changing of various inspection vehicles with externally suspension type steel girder boxes, and are high in automation degree, fine in reliability and convenient in operation. The technical scheme includes that the track changing control system comprises a detector switch, an operation unit, an encoder, a controller, a driving unit and a rotation mechanism, the detector switch is used for detecting whether the inspection vehicle reaches a center position of a rotation track or not and transmitting detection signals to the controller, direction control signals are transmitted to the controller by the operation unit, the encoder is used for detecting rotational angle of the rotation mechanism, the controller is used for receiving angle information outputted by the encoder and the direction control signals of the operation unit, carrying out logic judgment and operation according to the angle information and outputting control signals to the driving unit, and the driving unit drives a rotation motor to rotate at different speeds or stop according to the control signals.

Description

technical field [0001] The invention relates to a control technology for rail transition of an inspection vehicle outside a steel box girder, in particular to an automatic rail transition control system and a control method for an inspection vehicle. Background technique [0002] In order to carry out all-round and full-dimensional inspection and maintenance on the outside of the steel box girder, the steel box girder bridge inspection vehicle needs to change the track to pass through the pier, and use the horizontal track change to check the blind area when walking straight outside the tower (pier). Before the orbit changing operation, the active rotating orbit must be controlled to realize the orbit changing function. [0003] In the traditional track transition control, the mechanical manual rotating track or electric manual control are mainly used, but due to the low degree of automation and no detection mechanism, the maintenance time is wasted and the labor intensity o...

Problems solved by technology

When the track is rotated 90° into place, the speed of the slewing mechanism is manually adjusted by observing the positions of the slewing track and the fixed track. Sometimes it is necessary to repeatedly adjust the position several times to align the fixed track and the slewing track, which wastes time and resources. , which increases the labor intensity
