Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

The first embodiment is as follows: a small-radius turning device for a low-speed train and a train track are disclosed, referring to figures 1 and 2, comprising a plurality of guide members 2 for guiding the train to make a turn, wherein the plurality of guide members 2 are arranged on both sides of a small-radius turning path of the train, the guide members 2 on each side are arranged along the small-radius turning path of the train, and bogies on both sides of the train are respectively in contact with the guide members 2 on both sides of the turning path.

When the train makes a small radius turn, the train is guided to make a small radius turn by the guide members 2 at both sides of the train.

When the train is turning at the small radius, take place to twist reverse between wheel and the rail 1, thereby make wheel or rail 1 appear the damage easily, in order to avoid the damage of wheel and rail 1, when the train is turning at the small radius, break away from wheel and rail 1, make the wheel can not produce the twist and make rail 1 and wheel be difficult to appear the damage with rail 1 between 1, for example, set up a protection shield plate 3 between two rail 1, the height that sets up protection shield plate 3 top and the top parallel and level of rail 1, thereby make the train when turning at the small radius, the wheel can break away from and support and accomplish the small radius with the train and turn at protection shield plate 3 top.

The wheel still can twist reverse for protection shield 3 when carrying out the minor radius turn at protection shield 3 top, in order to prevent that the wheel from receiving the injury, sets up protection shield 3 into plasticity protection shield 3 and make protection shield 3 have high plasticity to when making the wheel take place to twist reverse on protection shield 3, be difficult to appear the damage.

In order to enable the wheel to be separated from the steel rail 1 and to travel to the protection plate 3 in the process of turning with a small radius, the wheel needs to be separated from the steel rail 1 at the bend and to travel upwards to the protection plate 3, for example, a guide slope 4 is arranged at one end of the protection plate 3 close to the bend, and the wheel moves upwards under the guidance of the guide slope 4, so as to be separated from the steel rail 1 and move the top of the protection plate 3.

The wheel of the train is usually provided with a wheel flange at the outer side, the wheel flanges of the wheels at the two sides of the bottom of the train are arranged at the sides of the two steel rails 1 close to each other, and the wheel flanges are contacted with the guide slope surface 4 when the wheel is guided to move to the top of the protection plate 3 through the guide slope surface 4. In this embodiment, two guiding slopes 4 are provided, and are located at two sides of the protection plate 3 respectively, and the two guiding slopes 4 are used for guiding wheels at two sides of the bottom of the train to move upwards to the top of the protection plate 3 respectively.

In this embodiment, two guiding grooves 31 are disposed on two sides of the protection plate 3 near the end of the bend, and two guiding slopes 4 are disposed in the two guiding grooves 31 respectively.

In order to reduce the abrasion to a train bogie when a train turns, the rotating roller comprises a central shaft 21 and a rotating sleeve 22 sleeved outside the central shaft 21, the rotating sleeve 22 is arranged to be rotatably connected with the central shaft 21, and the bogie is in contact with the rotating sleeve 22; when the guide member 2 is in contact with the train bogie to guide the train to turn, the rotation of the rotating sleeve 22 replaces the friction between the rotating sleeve 22 and the train bogie, thereby reducing the abrasion of the train bogie and making the turning process of the train smoother.

In order to ensure the stability of the position during the turning of the train guided by the turning rollers, the bottom end of the center shaft 21 is provided to be inserted downward into the ground.

Preferably, in the embodiment, the rotating sleeve 22 is rotatably connected with the central shaft 21 through a bearing, and a bearing is arranged at the top and the bottom of the rotating sleeve 22, so that when the rotating sleeve 22 is in contact with the train bogie, the rotating connection relationship between the rotating sleeve 22 and the central shaft 21 is not easily affected by external force.

The working principle of the small-radius turning device for the low-speed train when in use is as follows: when the train makes a small-radius turn, the train is guided to make a small-radius turn by the guide pieces 2 on the two sides of the train, wheels are separated from the steel rail 1 by the guide slope surfaces 4 and move upwards to the top of the protection plate 3, and the wheels and the steel rail 1 in the turning process are protected.

Example two: a train track, see fig. 1 and 2, comprising two rails 1 and a small radius turning device for low speed trains in the first embodiment arranged at the two rails 1, wherein one side of the two rails 1 facing away from each other is provided with a plurality of guides 2, and the plurality of guides 2 at each side are arranged along the small radius turning path of the train; the protective plate 3 is arranged between the two rails 1.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
