AI Technical Summary
When existing sleeper replacement vehicles excavate ballast under sleepers, ballast tends to accumulate at the rear end of the undercutting device, causing chain rotation to be obstructed and power loss to increase. In severe cases, the machine needs to be stopped for manual cleaning. Furthermore, the accumulated ballast exacerbates wear on the chain and guide rails, reducing their service life.
Design an excavation attachment including a first excavation component and a second excavation component. The first chain belt has excavation teeth on its outer side, and its cyclic rotation direction has an angle of 0° to 20° with the horizontal plane. The second chain belt rotates vertically and has a pusher plate. Ballast is transported to the second chain belt through the first chain belt and guided away. The transport direction of the second chain belt has an angle of 20° to 50° with the horizontal plane. The first and second chain belts are arranged vertically. The rotation speed of the second chain belt is higher than that of the first chain belt. It is equipped with a protective cover and a rubber baffle to limit the ballast splash range.
It effectively solved the problem of chain rotation obstruction caused by ballast accumulation, improved work efficiency, reduced component wear, ensured the continuity and efficiency of ballast clearing operations, and enhanced on-site safety.
