Abstract

The invention discloses a rack rail train track-entering mechanism which comprises two support bases and a rack rail, wherein the two support bases are arranged in parallel and have the interval distance equal to the interval between two wheels of a wheel pair, the rack rail is parallel to the support bases and is arranged at the middle position of the two wheels of the wheel pair, a plurality of rolling shafts are horizontally and transversely arranged on each support base, and a bearing is arranged on each rolling shaft. The invention is used for transition of the rack rail train from the common railway to the rack rail, and wheels roll on the rolling track when the gears and the rack rail are opposite to each other, so that the safety of the wheels and the train can be effectively protected; the structure is simple, but solves the old problem existing in the technical field for the first time, the abrasion of the wheels and the steel rails is greatly reduced after the wheels are prevented from forcedly sliding and dragging, the service life is prolonged, and the maintenance and replacement costs are reduced.

Description

Rail-feeding mechanism of toothed rail train

Technical Field

The invention relates to a rack rail train track-entering mechanism which is mainly applied to guide transition of a rack rail train from a common rail to a rack rail, and belongs to the technical field of locomotive rail traffic.

Background

The toothed rail railway is characterized in that a special toothed rail is additionally arranged in the middle of a common rail. A locomotive for running a toothed rail railway is provided with one or more gears, and is meshed with the toothed rail to run so as to pull the train up a steep slope with a large gradient. By means of the rail and toothed rail combination mode, the train can run on flat ground and mountain climbing railways with larger gradients, and passengers can not need to transfer.

When the common railway enters the toothed rail railway, the toothed rail and the gear are required to be meshed stably and safely. At present, the common railway directly enters the toothed rail railway, relative sliding or jumping can occur between wheels and the rail when the gears and the toothed rail are opposite to each other, and the wheels are easy to scratch or derail, so that the service life is influenced, and the replacement and maintenance cost is increased.

Disclosure of Invention

The invention aims at: aiming at the problems, the track-entering mechanism of the rack rail train is provided, and is used for enabling the train to enter the rack rail from the common rail to be in smooth transition. The correct phase position must be ensured when the rack and the traction gear are meshed, otherwise, top teeth can occur. Under the condition that a rolling track is not arranged, when the gears and the toothed rail are in tooth alignment, relative sliding or jumping can occur between the wheels and the track, so that the wheels are scratched or derailed; after the rolling track is used, wheels roll on the rolling track when the traction gear and the toothed rail are opposite to each other, so that the safety of the wheels and the train can be effectively protected.

The technical scheme adopted by the invention is as follows:

the utility model provides a rack train goes into rail mechanism, includes two support base, a rack, two support base parallel arrangement and interval distance equals the two wheel intervals of wheel pair, the rack is parallel with support base and set up in the two right intermediate position of wheel pair, every support base is gone up the level and is transversely set up a plurality of roll axis, installs the bearing on every roll axis.

Preferably, the bearings are arranged side by side and close together, and form a rolling track together with the rolling shaft and the support base, and the rolling track is used as a substitute of a common track when a train enters the track.

Preferably, the rolling track is arranged between the common track and the toothed rail as a guide transition, so that the wheel set rolls with the bearings on the rolling track.

Preferably, the support base is of a U-shaped steel structure, and the rolling shaft and the bearing are horizontally and transversely arranged in a U-shaped groove of the support base.

Preferably, two ends of the rolling shaft are fixedly connected with the supporting base, and the bearing inner ring is connected with the rolling shaft in an interference fit manner.

In summary, due to the adoption of the technical scheme, the beneficial effects of the invention are as follows:

1. the transition device is used for the transition of the rack rail train from the common railway to the rack rail railway, so that the phenomenon that wheels are scratched or derailed due to relative sliding or jumping between the wheels and the rail when the gears and the rack rail are opposite to each other is avoided;

2. the structure is simple, but solves the old problem existing in the technical field for the first time, the abrasion of the wheels and the steel rails is greatly reduced after the wheels are prevented from forcedly sliding and dragging, the service life is prolonged, and the maintenance and replacement costs are reduced.

Drawings

Fig. 1 is a schematic cross-sectional view of the present invention.

Fig. 2 is a schematic view of the invention in the a-direction shown in fig. 1.

The marks in the figure: the novel gear is characterized in that the novel gear is composed of a bearing 1, a rolling shaft 2, a supporting base 3, a toothed rail 4, a wheel set 5 and a traction gear 6.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Examples:

as shown in fig. 1 and 2, the rack rail train track-entering mechanism comprises two support bases 3 and a rack rail 4, wherein the two support bases 3 are arranged in parallel, the interval distance is equal to the interval between two wheels of a wheel set 5, the rack rail 4 is parallel to the support bases 3 and is arranged at the middle position between two wheels of the wheel set 5, a plurality of rolling shafts 2 are horizontally and transversely arranged on each support base 3, and a bearing 1 is arranged on each rolling shaft 2. The bearings 1 are arranged side by side and close together, and form a rolling track together with the rolling shaft 2 and the supporting base 3. The support base 3 is of a U-shaped steel structure, and the rolling shaft 2 and the bearing 1 are horizontally and transversely arranged in a U-shaped groove of the support base 3. The two ends of the rolling shaft 2 are fixedly connected with the supporting base 3, and the inner ring of the bearing 1 is connected with the rolling shaft 2 in an interference fit manner. The rolling track is arranged between the common track and the toothed rail track as a guiding transition section, and when the traction gear 6 and the toothed rail 4 are toothed, the wheel set 5 rolls along with the bearing 1 on the rolling track.
