Wherein like reference numerals denote like elements, and the element numerals are described as follows: the beam comprises a beam top plate 1, a beam web plate 2, a beam bottom plate 3, a limiting body 4, a roadway plate 5, a boss 6, a groove 7 and a transverse abutting adjusting piece 8.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, the utility model provides a single track rail structure of suspension type, including a plurality of sections track roof beams, each track roof beam all includes roof beam 1, sets up at the web 2 of the 1 left and right sides of roof beam and sets up at the beam bottom plate 3 of 2 lower extreme of web to all be provided with beam bottom plate 3 under the web 2 of both sides.

The beam bottom plate 3 comprises a limiting body 4 and a roadway plate 5 which are fixedly connected together, wherein the limiting body 4 is a plate body, the limiting body 4 is positioned on the outer side of the web plate 2, and the roadway plate 5 is positioned on the inner side of the web plate 2. Furthermore, the beam bottom plates 3 below the beam web plates 2 on the two sides are provided with limiting bodies 4. The limiting body 4 is arranged on the beam bottom plate 3 on one side, so that the limiting effect can be achieved, the balance force can be achieved by arranging the limiting body on two sides, and the limiting effect is enhanced.

For two opposite side surfaces of the limiting body 4 of two adjacent sections of track beams, one side surface is provided with a boss 6, the other side surface is provided with a groove 7 corresponding to the boss 6 so as to form a transverse limiting structure, so that the two adjacent beam bottom plates 3 are limited to move along the left and right direction, and the side surface of the boss 6 and the side surface of the groove 7 are closely arranged. The boss 6 of the transverse limiting structure is square, the transverse limiting structure further comprises a transverse abutting adjusting piece 8, and the transverse abutting adjusting piece 8 is a bolt. After the transverse abutting adjusting piece 8 is installed, gap filling materials are arranged in the gap on the left side and the gap on the right side of the boss 6.

The track beam is an open thin-walled section, and can generate certain transverse deformation under the action of live load, wherein the transverse direction is perpendicular to the driving direction of the vehicle. When the vehicle runs near the beam seam, one end of the beam seam is transversely deformed, and the other end of the beam seam is not transversely deformed, so that the phenomenon of slab staggering can occur, and the driving is not favorable. And the spacing body 4 sets up the lower extreme at whole track roof beam, is located the opening part of track roof beam, and its restraint is more direct effective. Particularly, mutually supporting between the spacing body 4 can play horizontal limiting displacement, and the lateral displacement restriction of two adjacent track roof beams is strong for unanimity, avoids the lane board 5 to appear the wrong platform problem to when improving the security and the travelling comfort of driving, reduce the wearing and tearing to the vehicle rubber tyer, and then prolong its life. The limiting body 4 is a plate body, so that the required added materials are less, and the economic efficiency is good.

The square boss 6 has a good transverse limiting effect, and can be easily matched with the groove 7, so that the difficulty in mounting the track beam is reduced. The transverse abutting adjusting piece 8 can fix the transverse positions of the boss 6 and the groove 7, the phenomenon that the transverse limiting effect is reduced due to the fact that gaps exist between the side face of the boss 6 and the side face of the groove 7 is avoided, further gap filling materials are arranged, the influence caused by the gaps between the boss 6 and the groove 7 can be reduced, and the transverse limiting effect of the boss 6 and the groove 7 is improved.

In particular, when a train travels to one track beam in the track beam direction, the section of track beam through which the train passes is laterally displaced due to the lateral force, while the next section of track beam in the train traveling direction is not laterally displaced due to the lack of pressure. At the moment, slab staggering is formed between the two sections of track beams, and the slab staggering is extremely unfavorable for travelling. The limiting body 4 can transmit the transverse stress of one stressed track beam to the next track beam through the matching of the lug boss 6 and the groove 7, so that consistent transverse displacement is kept between the two track beams, and the problem of traveling caused by slab staggering is solved. Thereby improving ride comfort and safety.
