Non-stop three-section wheel rail-rack rail transition device for rack rail traffic system

Abstract

A non-stop three-section wheel rail-rack rail transition device for a rack rail traffic system is used for enabling smooth transition of a rack-rail vehicle from a wheel-rail section to a rack rail section to guarantee stability and safety in operation of the vehicle. The non-stop three-section wheel rail-rack rail transition device comprises a rack rail mounted between steel rails on two sides, arack transition device, a roller transition device and a slope transition device are sequentially arranged in front of a driving-in end of the rack rail, the slope transition device, the roller transition device and the rack transition device sequentially act on driving gears passing through the rail-rack vehicle to enable relative slide between driving wheels of the rail-rack vehicle and the steel rails by vertical force, and the driving gears and the rack rail are effectively meshed when the vehicle enters the driving-in end of the rack rail.

Description

Technical field [0001] The invention relates to a rack railway, in particular to a non-stop three-section wheel-rail-tooth rail transition device used in a rack-rail transportation system. Background technique [0002] Cog-rail transportation is a rail transportation system suitable for medium and short distance, small and medium passenger flow transportation in mountainous areas. Compared with the traditional rail transit system, its notable feature is that a rack or stepped tooth parallel to the rail is laid in the middle of the rail, and a corresponding gear is installed on the axle of the bogie. When the vehicle is driving on a line with a relatively large slope, the meshing force between the gear and the rack can overcome the problem of insufficient adhesion between the steel wheel and the rail. Relying on the remarkable feature of strong climbing ability, the cog railway system is particularly suitable for mountain tourism transportation, and therefore has broad applicatio...

AI Technical Summary

Problems solved by technology

Before the initial meshing of the gear and the rack of the rack vehicle, there is no pre-adjustment structure to avoid the serious top teeth phenomenon of the gear and the rack, so the safety and reliability of the system are low

At the same time, there is no support or buffering device at the bottom of the side where the rack enters, so the rack is prone to damage when the force between the gear and the top teeth of the rack or the gear is too large, resulting in safety accidents

In addition, the device is completely meshed through the mutual adjustment between the gear and the rack, which makes the structure of the gear and the rack at the driving end severely worn, thereby increasing the operation and maintenance cost

[0004] Domestic research on key technologies such as the wheel-rail-to-rack transition device of the cog-rail transportation system has not yet been carried out
