Description
Technical Field
[0001] The utility model relates to the technical field of anti-dumping of ladder vehicles, in particular to an insulating slidable anti-dumping device used for a ladder vehicle. Background Art
[0002] In the professional construction, inspection and maintenance of railway electrification, ladder cars are the most commonly used tools. However, when the ladder car is in use, it will tilt to one side of the rail. At this time, an anti-dumping device is needed to prevent the ladder car from tilting or falling off the track.
[0003] For example, a ladder car anti-tilting device with publication number CN214532756 is a device for preventing the ladder car from tipping over by pulling the eccentric wheel operating lever to unfold the side guide wheel, and then the ladder car connecting plate and the ladder car chassis are fixed as a whole through the ladder car connecting bolts, and the eccentric wheel operating lever is pulled to clamp the side guide wheel and the rail, thereby realizing the clamping of the ladder car and the rail, thereby ensuring the stable connection between the ladder car and the rail, while ensuring that the ladder car can be pushed and used, the left and right shaking of the ladder car is limited, and the risk of the ladder car tipping over is reduced; if the ladder car is to pass through the turnout area or there are other obstacles installed closely next to the rail, the eccentric wheel operating lever is first pulled to unfold the side guide wheel, and after the ladder car is pushed through the affected area, the eccentric wheel operating lever is pulled to clamp the side guide wheel and the rail again;
[0004] When the above technical solution is in use, the ladder car is stably connected to the rails through the side guide wheels to prevent the ladder car from swaying left and right during the pushing process.
