A slope construction anti-rollover device and an application method thereof

ActiveCN118419091BRail derailment preventionEarth drilling and miningHydraulic cylinderTrackway
The application discloses an inclined shaft construction anti-rollover device and an application method thereof. A track vehicle can move in an inclined shaft along a track through external traction. An anti-rollover mechanism is installed on a working platform of the track vehicle, and a slag removing mechanism is also installed on the track vehicle. When the track vehicle moves forward and backward along the track under the action of external traction, the track vehicle drives the anti-rollover mechanism and the slag removing mechanism to move in the inclined shaft. The slag removing mechanism can rotate on the working platform to perform slag removing work on the wall surface around the parking position of the track vehicle. When the slag removing mechanism works, an intelligent control strategy is adopted to adjust the support pressure of a hydraulic cylinder of the anti-rollover mechanism according to the stress of the slag removing mechanism and the stress of the track vehicle, so that the track vehicle is prevented from rolling over due to the force between the slag removing mechanism and the wall surface of the inclined shaft during the slag removing work. The application has the advantages of simple structure and high reliability, and the safety and working performance of the track vehicle and the working device are considered.
