Embodiment 1

[0027] A road guardrail capable of applying corrective thrust to vehicles, as attached figure 1 As shown, its composition includes: a block 1, a load-bearing rod 2 is placed on the block, a long rod 3 is arranged above the load-bearing rod, the long rod is connected to a triangle bracket 4, and the long rod is connected to an extension rod 5.

[0028] The piles are required to be manufactured with less material to produce higher strength products, and the guy wires cannot hinder the normal work of the piles. The existing product impacts the guardrail when the car collides is an instantaneous rigid impact. After the vehicle is reinstalled with the guardrail, it becomes a delayed and retractable impact, and the impact direction of the vehicle is corrected, which can Save the day and minimize the loss of traffic accidents.

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that, as attached figure 1 As shown, in the road guardrail that can apply correction thrust to the vehicle, the tripod bracket includes a stand pile 6, and the stand pile is connected to a rotating shaft 7, and the rotating shaft is connected to the upper inclined rod 8 of the tripod, and the upper inclined stay rod of the tripod is connected to The lower inclined stay rod 9 of the tripod is connected to the bottom of the pile, the upper inclined stay rod of the tripod is connected with the long rod at the apex of the lower inclined stay rod of the tripod, and the apex is connected with the slip ring 10 .

Embodiment 3

[0032] The difference between this embodiment and Embodiment 1 or Embodiment 2 is that, as attached figure 1 As shown, in the road guardrail that can apply correction thrust to the vehicle, two adjacent tripods are connected by a stay rope 11, and one end of the stay rope passes through the slip ring of the last tripod to connect to the load-bearing rod, The other end of the stay rope is connected to the top of the stake of the previous tripod.

[0033] The vertices of two adjacent triangular brackets are respectively hinged to one end of the load-bearing rod, and the other end is slidingly connected. The load-bearing rod can rotate around the pile at a certain initial position on the triangular bracket, and compress to the inner side of the road within a certain corner range to unload the collision of some vehicles. force.

Abstract

The invention discloses a road guardrail capable of applying corrective thrust on a vehicle, and a mounting method and a working method of the road guardrail. So far, all the road guardrails are fixed roadside facilities, and bear collision passively when the vehicle is out of control. The road guardrail capable of applying the corrective thrust on the vehicle comprises building blocks (1), wherein a bearing rod (2) is put on the building blocks; a long rod (3) is arranged above the bearing rod, and connected with triangular brackets (4) and an extending support rod (5); the two adjacent triangular brackets are connected by a pull rope; each triangular bracket is articulated with one end of the bearing rod, and is slidingly connected with the other end of the bearing rod; and an included angle of a vertex angle of each triangular bracket is 20-60 degrees. The road guardrail is used for applying the corrective thrust on the vehicle.

Description

technical field [0001] The invention relates to a road guardrail capable of applying correction thrust to vehicles and its installation and working methods. Background technique [0002] So far, all road guardrails are fixed facilities on the side of the road; when the vehicle loses control, it passively withstands the impact. It may protect the vehicle from rushing out of the roadside, or it may cause the vehicle to rush out of the roadside due to the high impact force of the vehicle. If the strength of the guardrail is not enough, the vehicle may crash into the river or mountain stream, causing serious car crashes as a result of. [0003] Chinese patent CN99111498.1 discloses a guardrail with a sliding impact receiving element. The impact receiving element in the guardrail with a sliding impact receiving element is installed at one end of the crossbar. This device can only be used at intersections to function. The protective effect is not comprehensive. Contents of the...
