Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, a high-strength and high-toughness stainless steel rail guard (hereinafter referred to as rail guard) according to an embodiment of the present utility model includes a wave beam plate 100, a blocking block 200, and a pillar 300, wherein the pillar 300 is connected to the wave beam plate 100 through the blocking block 200. In this embodiment, the number of columns 300 is plural, and the plural columns 300 are sequentially arranged along the length direction of the wave beam plate 100 to play a role in supporting the wave beam plate 100. The anti-blocking blocks 200 may be disposed in one-to-one correspondence with the columns 300, i.e., each column 300 may be connected to the wave beam plate 100 through the anti-blocking block 200.
Referring to fig. 2, the anti-blocking block 200 in the present embodiment includes a first connecting plate 210 and two second connecting plates 220, the two second connecting plates 220 are disposed opposite to each other, and the two second connecting plates 220 are respectively connected to opposite sides of the first connecting plate 210. In particular, the two second connection plates 220 may be disposed perpendicular to the first connection plates 210, so as to improve the overall stability of the anti-blocking block 200.
Referring to fig. 3, the second connection plate 220 is provided with a sliding groove 221, the sliding groove 221 includes a first end 221a and a second end 221b, wherein the first end 221a of the sliding groove 221 is located at a side of the second end 221b facing away from the first connection plate 210, and the height of the sliding groove 221 gradually decreases in a direction from the first end 221a to the second end 221 b. In the present embodiment, the height of the sliding groove 221 can be understood as the distance between the sliding groove 221 and the ground when the guard rail stands on both sides of the road.
The wave beam plate 100 has a front side and a rear side, and the wave beam plate 100 can be used to directly receive impact forces in actual use. When the column 300 is connected with the wave beam plate 100 through the anti-blocking block 200, the first connection plate 210 is connected with the back surface of the wave beam plate 100, the column 300 is located between the two second connection plates 220, each second connection plate 220 is connected with the column 300 through the first connection structure 230 and the second connection structure 240, wherein the first connection structure 230 is located outside the sliding groove 221, the second connection structure 240 is located inside the sliding groove 221, and the second connection structure 240 can slide along the extending direction of the sliding groove 221 relative to the sliding groove 221.
In combination with fig. 4 and 5, in practical application, when the guard rail is impacted externally, the impact force acts on the wave beam plate 100, and the impact force is transmitted to the anti-blocking block 200 because the wave beam plate 100 is connected with the anti-blocking block 200. Because the upright 300 is relatively fixed to the ground, the position of the upright 300 is fixed, and the position of the anti-blocking block 200 connected to the upright 300 by the first connection structure 230 is fixed, the anti-blocking block 200 can slide along the extending direction of the sliding groove 221 relative to the second connection structure 240 under the impact force, specifically, the anti-blocking block 200 slides along the direction from the second end 221b to the first end 221a of the sliding groove 221 relative to the upright 300. At this time, the position where the anti-blocking block 200 is connected to the pillar 300 by the second connection structure 240 is changed, and the height of the first connection plate 210, that is, the height of the wavy beam plate 100 is increased with respect to the initial state (when the guard rail is not impacted).
In addition, the materials of the wavy girder 100 and the column 300 in the present embodiment are stainless steel, or the materials of the wavy girder 100, the column 300, and the resistance block 200 in the present embodiment are stainless steel. That is, the main components or all components of the guard rail in the embodiment are made of stainless steel materials with higher yield strength, tensile strength and elongation after break, so that the guard rail in the embodiment can effectively improve bearing capacity and energy absorption level, can dynamically maintain protection height in the collision process, and can effectively prevent accidents such as riding, traversing, rollover and the like of an uncontrolled vehicle.
Notably, the guard rail in this embodiment is made of high-strength and high-toughness stainless steel, so that the guard rail can be light, the thickness of the wave beam plate 100 can be reduced to within 3.5mm, and the thickness of the upright post 300 can be reduced to within 4 mm.
In some embodiments, with continued reference to fig. 2 and 3, the shape of the sliding groove 221 is circular arc-shaped, and in particular, the sliding groove 221 is curved toward the bottom of the second connection plate 220. In addition, the sliding groove 221 is located near the top of the second connection plate 220, and the second connection structure 240 is correspondingly located near the top of the second connection plate 220. The first connection structure 230 is located at a position of the second connection plate 220 near the bottom, and the first connection structure 230 is located at an end of the second connection plate 220 away from the first connection plate 210. When the relative sliding occurs between the anti-blocking block 200 and the second connection structure 240, it can be considered that the anti-blocking block 200 rotates with the first connection structure 230 as a rotation center and with the distance between the first connection structure 230 and the sliding groove 221 as a rotation radius. In the above design, since the first connection structure 230 is far from the first connection plate 210, the rotation between the anti-blocking block 200 and the column 300 can be facilitated, and since the rotation radius is fixed, the rotation radius can be designed, thereby controlling the change of the height of the wave beam plate 100, and controlling the change of the height of the guard rail.
In other embodiments, the sliding groove 221 may have a linear structure, which is not limited in the present application.
In addition, the first ends 221a of the sliding grooves 221 may be positioned on the same line as the first connection structures 230, that is, arranged in the height direction of the column 300 between the first ends 221a of the sliding grooves 221 and the first connection structures 230. When the second connection plate 220 is connected to the column 300 through the second connection structure 240, the second connection structure 240 may be positioned at the first end 221a of the sliding groove 221. After the guard rail is impacted, the sliding path of the second connecting structure 240 relative to the sliding groove 221 can be from the first end 221a to the second end 221b of the sliding groove 221, so that the sliding path of the second connecting structure 240 can be increased as much as possible, and the height of the wave beam plate 100 can be increased as much as possible.
On the basis, when the rotation radius is fixed, the central angle of the sliding groove 221 can also determine the sliding path of the second connecting structure 240 relative to the sliding groove 221. It should be understood that, within a certain range, the larger the central angle of the sliding groove 221, the longer the sliding path of the second connection structure 240 with respect to the sliding groove 221. Therefore, by designing the central angle of the sliding groove 221, the height variation of the wavy girder 100 can be further improved. As one embodiment, the central angle of the sliding groove 221 may be 40 ° to 60 °.
Similarly, when the central angle of the sliding groove 221 is fixed, the sliding path of the second connection structure 240 with respect to the sliding groove 221 may also be controlled by designing the radius of rotation. At this time, by designing the position of the first connection structure 230 and the position of the first end 221a of the sliding groove 221, the specific size of the rotation radius may be designed according to the size of the second connection plate 220, which is not limited in this embodiment.
In some embodiments, the first connection structure 230 may be a bolt and the second connection structure 240 may be a bolt. The bolt connection mode not only can ensure the stability of connection between the second connecting plate 220 and the upright post 300, but also can be convenient to disassemble at any time so as to maintain the guard rail.
Referring to fig. 6, the first connection plate 210 may be provided with a plurality of bolt holes 211, and the plurality of bolt holes 211 are aligned in the height direction of the column 300. When the first connecting plate 210 is connected with the wave beam plate 100, the wave beam plate 100 can be connected with the wave beam plate 100 through a plurality of bolts penetrating through a plurality of bolt holes 211, so that the stability of connection between the first anti-blocking block 200 and the wave beam plate 100 is improved, and relative movement between the wave beam plate 100 and the anti-blocking block 200 is avoided when relative sliding occurs before the first anti-blocking block 200 and the upright post 300.
In some embodiments, the first connecting plate 210 and the second connecting plate 220 may be integrally formed, so that the overall structural stability of the anti-blocking block 200 is improved. On this basis, the material of the anti-blocking block 200 may be one of carbon steel, cast iron, cast aluminum, aluminum alloy, and stainless steel.
In addition, the column 300 of the present application may be a round tube, or may be a square tube, a rectangular tube, a C-shaped steel, a channel steel, an i-shaped steel, an H-shaped steel, or the like, which is not limited in the present application.
It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present utility model without departing from the spirit and scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
