The utility model is further described below with reference to the accompanying drawings.

The present utility model provides a rail guard 1000 for a level crossing, referring to fig. 1, including a rail 100, a road surface 200, and a supporting mechanism 600. The steel rail 100 is used for running the rail vehicle, the road surface 200 is used for running the road surface 200 vehicle (such as an automobile), and the intersection of the road surface 200 and the steel rail 100 is the position where the road surface 200 vehicle passes through the level crossing of the steel rail 100.

Referring to fig. 1 and 2, the road surface 200 is provided with a rail groove 300, and the rail 100 is installed in the rail groove 300. The rails 100 are arranged along the length of the rail groove 300. The supporting mechanism 600 is disposed in the rail groove 300 to fill the rail groove 300. Wherein the upper surface of rail 100 is flush with road surface 200 to facilitate the passage of road surface 200 vehicles across rail 100.

In this embodiment, the bottom of the rail 100 is provided with an iron plate 400 and a rubber pad 500, the bottom of the iron plate 400 is integrally formed with a hollow column 410, and the bottom wall of the rail groove 300 is provided with a hole structure matched with the hollow column 410. The iron plate 400 is attached to the bottom of the rail groove 300 and is fixed to the rail groove 300 by the hollow column 410. The lower side of the rubber pad 500 is attached to the upper side of the iron plate 400, and the upper side of the rubber pad 500 is attached to the bottom side of the rail 100. Rail 100 is fixed above iron plate 400 and clamps rubber gasket 500 together with iron plate 400.

In this embodiment, the rail 100 is an i-shaped rail, and both sides of the rail 100 have circular arc grooves 110. The rail 100 is provided at both sides with a plurality of pressing plates 120, and the pressing plates 120 are fixed to the iron plate 400 and extend into the arc-shaped grooves of the rail 100 to press the rail 100 down on the iron plate 400.

Specifically, in this embodiment, the inner cavity of the hollow column 410 at the bottom of the iron plate 400 is provided with an internal thread, and the pressing plate 120 is linked with a bolt, and the bolt cooperates with the internal thread of the hollow column 410 to fix the pressing plate 120 on the iron plate 400.

Referring to fig. 1 to 2, the supporting mechanism 600 is disposed in the rail groove 300 in parallel to the rail 100 and abuts against the rail 100, and fills the gap between the rail grooves 300 by the supporting mechanism 600, so as to prevent the road surface 200 from being impacted excessively when the vehicle crosses the track due to the excessively large gap between the rail grooves 300, and facilitate the vehicle on the road surface 200 to pass the track.

Specifically, the supporting mechanism 600 includes an upper pressing block 610, a rail pressing plate 620 and a tightening member 630, the upper pressing block 610 is fixed in the rail groove 300, and the upper pressing block 610 is detachably connected with the rail pressing plate 620. The side of the rail pressing plate 620 away from the upper pressing block 610 abuts against the steel rail 100, the upper pressing block 610 abuts against the side of the rail pressing plate 620 away from the steel rail 100, and the abutting member 630 abuts against between the inner wall of the rail groove 300 and the side of the upper pressing block 610 away from the rail pressing plate 620. The abutting member 630 and the rail pressing plate 620 jointly press the upper pressing block 610, and the upper pressing block 610 and the steel rail 100 jointly abut against the rail pressing plate 620, so that the supporting mechanism 600 and the steel rail 100 are matched and fastened, and the structure is reliable.

Wherein, the upper surface of the upper pressing block 610 is flush with the road surface 200 so that the road surface 200 vehicles smoothly pass through the track from the road surface 200 after passing through the upper pressing block 610. The upper surface of the rail pressing plate 620 is lower than the upper surface of the upper pressing block 610 and the upper surface of the steel rail 100, so that the steel rail 100 protrudes out of the rail pressing plate 620, and wheels of a railway vehicle can be limited between the steel rail 100 and the upper pressing block 610 and run along the upper surface of the rail pressing plate 620, thereby ensuring the normal operation of the railway vehicle.

Thus, the track guard 1000 of the present embodiment reduces the exposed width of the rail groove 300 and reduces the impact of a vehicle (e.g., an automobile) on the rail 100 when the road surface 200 passes through a level crossing. Meanwhile, the upper press block 610 and the rail pressing plate 620 cover the upper opening of the rail groove 300, so that sundries are prevented from falling into the rail groove 300 and are difficult to clean, and the support mechanism 600 is not prevented from normally operating and communicating with the rail vehicle by the rail pressing plate 620.

Referring to fig. 2 and 3, the upper press block 610 is hollow, and one end of the rail pressing plate 620 away from the upper press block 610 is bent downward, and the rail pressing plate 620 and the upper press block 610 enclose a cavity 640. Thus, the upper pressing block 610 and the rail pressing plate 620 can fill the rail groove 300 and reduce the weight and consumable materials, and the cavity 640 can facilitate the arrangement of other connecting components.

The bottom of the first vertical plate 611 is directly abutted against the bottom of the rail groove 300 through indirect abutment by other components, the vertical height of the second vertical plate 613 is smaller than that of the first vertical plate 611, and the second vertical plate 613 is abutted against the rail pressing plate 620, so that the space below the rail pressing plate 620 is communicated with the inner cavity of the upper pressing block 610 to form the cavity 640.

The rail pressing plate 620 is an L-shaped plate and comprises a vertical portion 621 and a horizontal portion 622 which are connected with each other, the vertical portion 621 is embedded into the circular arc-shaped groove 110 of the steel rail 100 to be abutted against the steel rail 100, and the horizontal portion 622 is arranged above the plate surface of the vertical portion 621 and is abutted against the second vertical plate 613 in a direction away from the steel rail 100.

Thus, this structure enables the upper press block 610 and the rail pressing plate 620 to better cover the rail groove 300 while ensuring a lightweight structure of the supporting mechanism 600, and to better support the road surface 200 through which the vehicle passes.

Wherein, the vertical portion 621 of the rail pressing plate 620 is bent downward and abuts against the bottom of the circular arc-shaped groove 110, and the bent portion where the horizontal portion 622 and the vertical portion 621 of the rail pressing plate 620 are connected is circular arc-shaped and abuts against the upper portion of the circular arc-shaped groove 110. The rail pressing plate 620 is reliably abutted with the steel rail 100, and the arc-shaped groove 110 is abutted with the arc-shaped bending part, so that the stress concentration can be avoided to damage the steel rail 100 or the rail pressing plate 620.
