Toothed rail train transition device

Abstract

The invention belongs to the field of rail traffic, and particularly relates to a toothed rail train transition device. The device comprises a toothed rail, a transition mechanism, two fixed gears, a jacking gear, a chain and a limiting stop dog, the toothed rail is fixed between two rows of steel rails, the transition mechanism is arranged in front of the driving-in end of the toothed rail and provided with the driving-in end and the driving-out end, the two fixed gears are arranged at the driving-in end and the driving-out end of the transition mechanism respectively, the jacking gear is arranged between the two fixed gears, the limiting check block is arranged on a rail bed between the two fixed gears, a first spring and a second spring are arranged at the two ends, in the length direction of the toothed rail, of the limiting check block correspondingly, the opposite ends of the first spring and the second spring are connected with a first fixed block and a second fixed block correspondingly, a boss is arranged at the end, close to the driving-out end of the transition mechanism, of the side wall of the limiting check block. According to the toothed rail train transition device, the meshing state of a driving gear is adjusted through the tensioning force of a chain, and it is guaranteed that the gear is accurately meshed with the chain.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, in particular to a transition device for rack trains. Background technique [0002] The cog railway is laid with a special rack in the middle of the ordinary track, and the vehicles running on the cog railway are equipped with one or more gears and a special rack meshing transmission between the track, so that the railway vehicle can move on the straight track. And run uphill on larger slope lines. At present, this type of railway vehicle has emerged abroad and is widely used in mountainous tourist and sightseeing railways, and is mostly used in coal mine transportation in China. The rack vehicle has a strong climbing ability, and can effectively reduce the length of the climbing line and reduce the bridge-tunnel ratio. It is especially suitable for long-distance transportation and complex and changeable terrain. [0003] In the process of realizing the present invention, the applic...

Problems solved by technology

[0005] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a cog train transition device to solve the problem that the conventional railway directly enters the cog railway, and when the gears and the cogs are aligned, the wheels and the rails will be opposite to each other. Sliding and jumping affect the safety of train operation and reduce the technical problems of the service life of joints
