Control system and method for plugging and unpinning of bridge body of bridge erecting vehicle and bridge erecting vehicle

Abstract

The invention provides a control system, a method and a bridge erecting vehicle for inserting and releasing pins of the bridge body of the bridge erecting vehicle. The control system includes: a first detection device, which is used to generate a first signal when the turning mechanism reaches a designated position, and transmit the first signal to the main control device. The position of the overturning mechanism outside the fulcrum; the main control device is used to judge the allowed actions of the overturning mechanism, the movable pin and the wire rope according to whether the first signal is received and the state of the movable pin. It solves the problem that the operator needs to go to the bottom of the bridge to confirm whether the turning mechanism has moved to the designated position and there is a great risk of personnel safety during the withdrawal process of the bridge body, which effectively improves the efficiency and safety of erecting and withdrawing the bridge body .

Description

technical field [0001] The invention relates to the field of emergency rescue equipment, and in particular to a control system for plugging and unpinning a bridge body of a bridge-erecting vehicle, a method for controlling pinning-out of a bridge body for a bridge-erecting vehicle, and a bridge-erecting vehicle. Background technique [0002] The emergency bridging vehicle is mainly used to quickly erect bridges, allowing vehicles and personnel to quickly pass through rivers, ravines, etc. After natural disasters such as rainstorms, floods, and mudslides, roads and bridges are often destroyed, causing delays in emergency rescue, and emergency bridge erection vehicles are generally used to quickly build roads and bridges during rescue to facilitate the passage of rescue vehicles. The bridge body of the bridge erecting vehicle and the turning mechanism are connected by movable pins to facilitate the combination and disengagement of the turning mechanism and the bridge body.

Problems solved by technology

[0003] When the existing emergency bridging vehicle withdraws the bridge body, it needs to move the overturning mechanism to the position where the movable pin can be inserted into the straight chute. Due to the infinite position reference, the position error is large, resulting in a large width of the straight chute. Due to the diameter of the movable pin, there is a large gap on the upper and lower sides of the straight chute after the movable pin is combined with the straight chute, so that there is a large impact during the erection and withdrawal of the bridge body by the turning mechanism, which increases the bridge erection. And the safety risk when withdrawing; on the other hand, when withdrawing the bridge body, it is necessary to move the overturning mechanism to the position where the movable pin can be inserted into the straight chute. Observing from a close distance whether the turning mechanism has moved to the designated position greatly increases the operating difficulty and safety risks of the operator, which may easily lead to casualties; the operator needs to repeatedly confirm whether the turning mechanism has moved to the designated position, which increases the bridge body.
