Problems solved by technology

There is no support or buffer device at the bottom of the side where the rack enters, so the rack is prone to damage when the force is too large, resulting in safety accidents
At the same time, the rotating arm mechanism of the device is complicated, and the amount of maintenance and repair is large.

Abstract

The invention discloses a toothed railway wheel rail-toothed rail transition device to enable a toothed rail vehicle to smoothly transit to a toothed rail section from a wheel rail section to ensure stable and safe operating of the vehicle. The toothed railway wheel rail-toothed rail transition device comprises a toothed rail mounted between steel rails on the two sides. A transition-section toothed rail is arranged in front of the traveling-in end of the toothed rail, a supporting arm is arranged in the middle of the upper portion of the transition-section toothed rail, a hydraulic cylinder is arranged at the traveling-in end, and a rotary arm is arranged at the traveling-out end. The upper ends of the supporting arm, the hydraulic cylinder and the rotary arm are hinged to the transition-section toothed rail, and the lower ends of the supporting arm, the hydraulic cylinder and the rotary arm are hinged to a sub-rail foundation through hinged supports. The hinged position of the supporting arm and the transition-section toothed rail is provided with an extension spring, and the two ends of the extension spring act on the transition-section toothed rail and the sub-rail foundation correspondingly. The traveling-in end of the transition-section toothed rail is provided with a roller parallel to rail teeth.

Description

technical field [0001] The invention relates to railways, in particular to a gear rail-tooth rail transition device for a rack railway. Background technique [0002] The cog railway is a kind of railway with strong climbing performance. It is different from the ordinary railway in that a special cog is laid in the middle of the track, mostly a rack, and it runs on the locomotive or motor car bogie on the cog railway. equipped with one or more gears. When the rack vehicle is climbing, the gear can be meshed with the rack to overcome the problem of insufficient adhesion between the steel wheel and the rail. When a rack vehicle drives from the wheel-rail section to the rack section, if the meshing between the gear and the rack is inaccurate, it may cause the top tooth phenomenon, which will directly affect the running stability and safety of the vehicle. In view of this, it is necessary to design a cog railway track entry device, which can improve the efficiency of production...
