Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-4, a guardrail for road traffic comprises a base 5, two columns 4 and two railings 1 arranged one above the other, wherein two ends of the railing 1 are respectively connected with the two columns 4, and the columns 4 are fixed on the base 5 to integrally form a support for the railing 1.

Because current conventional guardrail, its railing post 2 of connecting two railings 1 is a whole, when receiving the striking such as car, and railing post 2 is the stress deformation easily, and because railing post 2 is connected for rigid connection with railing 1, so difficult recovery after railing post 2 warp to it is not high to send guardrail life. For solving this problem, this technical scheme does not adopt the mode of a whole 4 lug connections of root post 1, but divide into two whole railing post 2, weld a railing post 2 on every railing 1 separately promptly, two railing posts 2 correspond the installation and adopt a buffer gear to couple together two railing posts 2, and then cushion through buffer gear when the guardrail receives the striking, with the atress of weakening railing post 2, can avoid railing post 2 atress to a certain extent to warp, and then promote the holistic life of guardrail. In addition, the railing post 2 on every railing 1 all has a plurality ofly to set up along railing 1 length direction equidistant.

According to the above concept, as shown in fig. 2 and 3, the damping mechanism adopted in the present technical solution includes a sliding sleeve 6 sleeved on the railing post 2, the railing post 2 adopts a cylindrical structure, so that the sliding sleeve 6 slides on the railing post 2, a spring 7 is sleeved on the railing post 2 between the sliding sleeve 6 and the railing 1, two ends of the spring 7 are respectively welded with the sliding sleeve 6 and the railing 1, and then two corresponding side walls of the two sliding sleeves 6 are connected through a damping rod set, that is, the two corresponding sliding sleeves 6 are connected through two sets of damping rod sets.

The buffer rod group comprises connecting rods 8 arranged on the side walls of the two sliding sleeves 6, as shown in fig. 3, the connecting rods 8 can be rotatably connected with the side walls of the sliding sleeves 6 through a conventional shaft pin structure, one ends of the two connecting rods 8 are hinged with each other, and the hinged ends of the two connecting rods 8 extend out of the plane where the side walls of the balustrade 1 are located so as to bear the external impact force. In order to further enhance the overall strength, as shown in fig. 2, two connecting rods 8 on the side wall of each sliding sleeve 6 are connected through a plurality of reinforcing rods 9.

After adopting above-mentioned buffer structure, when the guardrail received the striking, the direct atress of the hinged end of two connecting rods 8, under the external impact force, two connecting rods 8 promote respectively to connect sliding sleeve 6 to slide to railing 1 on railing post 2, spring 7 consequently compresses, with this alright weaken external impact force, realize the cushioning effect, and then prevent that railing post 2 warp because of the atress, external force disappears the back, buffer structure wholly gets back to initial condition under the effect of spring 7 restoring force, finally realize promoting the holistic anti striking ability of guardrail and the life who promotes the guardrail.

In addition, in order to facilitate the combination of a plurality of guardrails for the protection of curved roads, the guardrail 1 and the upright post 4 in the technical scheme are rotatably connected and can be detached. Specifically, as shown in fig. 4, two opposite side walls of the upright post 4 are provided with movable cavities 13, the top surface and the bottom surface of each movable cavity 13 are provided with grooves 14, a bearing 15 is arranged in the groove 14, two ends of each railing 1 are provided with bayonets 10, then the railings 1 and the upright posts 4 are connected through a rotating block 3, wherein the shape and the configuration of one end of the rotating block 3 are matched with the bayonets 10, that is, the end can be clamped into the bayonet 10 and then connected with the end of the handrail 1 through the pin 11, the other end of the rotating block 3 is integrally formed with a rotating shaft 12, the two ends of the rotating shaft 12 extend outwards so as to be respectively sleeved with two bearings 15 in the movable cavity 13, and finally, the upper railing 1 and the lower railing 1 are used as a group, and after a plurality of groups of railing groups are connected and combined into a whole through the upright post 4, the rotating angle of each group of railing groups can be adjusted according to requirements so as to meet the protection requirements of different roads.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
