Description

Track

Technical Field

The invention relates to the technical field of walking supporting devices, in particular to a track.

Background

The more common rail that is exactly that the track is for the train, traditional rail all are straight butt joint, for the deformation of release rail expend with heat and contract with cold, still can leave the gap between the rail, just can produce the striking when the wheel passes through, sends the noise of shaking the ear. The rails of the high-speed rail are welded together by adopting a seamless paving technology, and then are subjected to leveling treatment, so that the impact sound of the wheels is eliminated. However, the method for paving the high-speed rail is only suitable for the steel rails capable of being welded, and is not suitable for the rail made of the nonmetal high polymer. The nonmetal high-molecular rails are usually used in the production lines of factories, the conventional paving method is similar to the conventional steel rails and is straight and butt-jointed, in order to eliminate the impact sound between the wheels of the traveling vehicle and the rails, the technical means of keeping the temperature and reducing the butt joint are generally adopted, not only the construction cost is increased, but also the traveling vehicle still has slight vibration and generates impact noise, and the quality of products in the traveling vehicle is influenced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be understood that the terms "front," "back," "left," "right," "upper," "lower," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings and are used for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and are therefore not to be considered limiting of the scope of the invention.

Example one

As shown in fig. 1: the present embodiment provides a track, which includes a first half track 1 and a second half track 2 disposed side by side, and can be formed by fixedly connecting common tracks side by side, that is, the width of the track of the present embodiment can be selected to be twice of the width of a conventional track, and on the premise that the supporting rigidity is sufficient, the width of the first half track 1 and the second half track 2 of the present embodiment can be appropriately reduced relative to the common track, but should not be less than half of the width of the common track.

The cross sections of the first half rail 1 and the second half rail 2 are preferably symmetrically arranged, the lengths of the first half rail 1 and the second half rail 2 are equal, and the lengths are not longer than 3 meters under the limitation of a production process. The upper end faces of the first half rail 1 and the second half rail 2 are flush, the rail is used for supporting wheels of the walking vehicle, and the width of the wheels is not less than the sum of the widths of the first half rail 1 and the second half rail 2.

Half rail 1 of a plurality of and half rail 2 of a plurality of second can infinitely splice in length direction, and the splice seam 3 between the adjacent half rail 1 sets up with the splice seam 3 between the adjacent half rail 2 of second is crisscross, and the splice seam 3 between the adjacent half rail 1 aligns with the middle part of the half rail 2 of second.

During the laying process, if the half rails on both sides of the splice seam 3 are found to be high, they can be ground appropriately. Preferably, the end of the adjacent first half rail 1 is connected with the same second half rail 2 through a bolt; the end part of the adjacent second half rail 2 is connected with the same first half rail 1 through a bolt, so that the flatness of the half rails on two sides of the splicing seam 3 and the integral rigidity of the rail are improved.

In the embodiment, the splicing seams 3 of the first half rail 1 and the second half rail 2 are arranged in a staggered manner, so that noise and vibration generated when the wheels travel through the splicing seams 3 of the rails are reduced, and other technical features which are not described are well known to those skilled in the art and are not described again. And the first half rail 1 and the second half rail 2 in this embodiment can be spliced by adopting a conventional straight butt joint method, common technical workers can all be competent, the construction difficulty is low, the installation cost is low, and if the rail of this embodiment is worn and damaged in the use process, simple and quick repair can be realized by replacing a single first half rail 1 or second half rail 2, so that the rail has better economical efficiency. And the track of this embodiment is not limited to nonmetal polymer track, is applicable to the rail equally, provides a new technical scheme for the laying of silence rail.

Compared with other technical schemes for sleeving or changing the shape of the splicing seam, the embodiment limits the warping of the end parts of the first half rail 1 and the second half rail 2 by utilizing the whole rail, and the rail at the splicing seam 3 has better rigidity and bending resistance and lower requirement on a rail supporting structure.

Example two

As shown in fig. 2, the present embodiment is different from the first embodiment in that: the splicing seam 3 between the adjacent first half rails 1 is close to the end part of the second half rail 2. The approach refers to the closer distance of the splice seam 3 between adjacent first rail halves 1 from the ends of the second rail half 2 relative to the middle of the second rail half 2. In this case, the first half rail 1 and the second half rail 2 adjacent to each other in the length direction may be connected by bolts, so that the two first half rails 1 and the two second half rails 2 on two sides of the two staggered splicing seams 3 are connected by three bolts, but four bolts are required in the first embodiment. Other technical features and technical effects can be seen in the first implementation.

The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
