Description

Technical Field

[0001] The utility model belongs to the field of ballastless tracks, and specifically relates to a ballastless track device that does not require drilling holes. Background Art

[0002] A ballastless track, also known as a completely new type of track, is a special railway track structure. Compared with traditional ballast tracks or concrete tracks, a new material that does not require laying ballast or concrete is used for the support of the track bed in a ballastless track.

[0003] The main components of a ballastless track include:

[0004] Sleeper: Special sleepers are used in ballastless tracks, which can be steel sleepers or plastic sleepers. The main function of the sleeper is to support and fix the rails of the track.

[0005] Track slab: The track slab is a structure similar to the roadbed on a traditional ballast track, but does not require laying ballast. The track slabs are distributed between the sleepers and play a role in supporting the sleepers and dispersing the track load.

[0006] Rail: Traditional rails are used as the railway tracks in ballastless tracks, which are responsible for bearing the train load and guiding the train operation.

[0007] Support formwork: Connected to the outside of the track slab and used to connect to the ground, playing a role in stabilizing the track slab and providing support.

[0008] However, when the traditional support formwork is connected to the beam surface, it is necessary to drill holes and install bolts, which causes certain damage to the beam surface. Content of the Utility Model

[0009] Technical problem to be solved: How to avoid drilling holes in the beam surface.

[0010] Technical solution: The utility model provides a ballastless track device that does not require drilling holes, including a combined structure and a separate structure: The combined structure includes two parallel tracks. At the bottom end of each track, a plurality of uniformly distributed support piers for supporting it are connected. A plurality of uniformly distributed cross beams are connected through the two tracks. Vertical connecting columns connected to the ground are vertically connected to both ends of the cross beam; in addition, side plates located below the cross beam and outside the support piers are symmetrically arranged on both sides of the two tracks. A plurality of round rods are connected to the outer ends of the side plates; The separate structure includes an outer wall connected to the outer ends of a plurality of round rods on one side and a connecting plate connected to the outer ends of a plurality of round rods on the other side. An outer beam is also arranged on the outside of the connecting plate, and a connecting mechanism is arranged between the two to further fix the connecting plate and the connecting column at the same time.

[0011] Furthermore, the connecting mechanism includes a plurality of uniformly distributed cross bars fixedly connected between the outer beam and the connecting plate, and a plurality of uniformly distributed and inclined long struts connected between the outer beam and the connecting column.

[0012] Furthermore, the top end of the long strut is near the top end of the connecting column, and its bottom end is near the bottom end of the inner side of the outer beam.

[0013] Furthermore, the bottom end of the long strut can be connected to a connecting frame, which is connected to both the inner side of the outer beam and the ground.

[0014] Furthermore, an inclined short strut can also be connected between the inner side of the outer wall and the connecting column.

[0015] Technical effect: In the present utility model, whether it is the round bar on either side or the cross bar in the connecting mechanism, the overall support structure formed by them is a straight-line structure. These support structures can support the beam surface instead of the traditional punching connection during support, and will not damage the beam surface. Description of the Drawings

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0021] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] The ballastless track non-drilling device provided by this specific embodiment is as Figure 1 and Figure 2 shown, including a combined structure and a separate structure, where:

[0023] The combined structure includes two parallel tracks 1. At the bottom end of each track 1, a plurality of uniformly distributed support piers 2 for supporting it are connected. A plurality of uniformly distributed cross beams 3 that are perpendicular to the tracks 1 penetrate and connect between the two tracks 1. At both ends of the cross beam 3, vertical connecting columns 4 connected to the ground are perpendicularly connected; in addition, on both sides of the two tracks 1, side plates 5 located below the cross beam 3 and outside the support piers 2 are symmetrically arranged. The side plates 5 are parallel to the tracks 1, and a plurality of round rods 6 are connected to the outer ends of the side plates 5;

[0024] The separate structure includes an outer wall 8 connected to the outer ends of a plurality of round rods 6 on one side and a connecting plate 7 connected to the outer ends of a plurality of round rods 6 on the other side. An outer beam 9 is also arranged on the outer side of the connecting plate 7. A connecting mechanism 10 for further fixing the connecting plate 7 and the connecting column 4 simultaneously is arranged between the two. The connecting mechanism 10 includes a plurality of uniformly distributed cross bars 1001 fixedly connected between the outer beam 9 and the connecting plate 7 and a plurality of uniformly distributed and obliquely arranged long struts 1002 connected between the outer beam 9 and the connecting column 4. Specifically, the top end of the long strut 1002 is at a position close to the top end of the connecting column 4, and its bottom end is at a position close to the inner bottom end of the outer beam 9. The overall support structure composed of these struts is a linear structure. When these support structures are supporting, they can support the beam surface instead of the traditional drilling connection and will not damage the beam surface.

[0025] In addition, as Figure 2 shown, the bottom end of the long strut 1002 can be connected to a connecting frame 11, and this connecting frame 11 is both connected to the inner side of the outer beam 9 and connected to the ground. It is equivalent to a two-way fixation, further improving the stability.

[0026] In addition to the above, for the side with the outer wall 8, an inclined short strut 12 can also be connected between the inner side of the outer wall 8 and the connecting column 4. This short strut 12 corresponds to the long strut 1002, but due to distance limitations, its length is slightly shorter.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
