Embodiment approach

[0024] As an embodiment of the present invention, the connecting block 9 includes a connecting rod 91, a plug 92, and a cylinder 93, one end of the cylinder 93 is fixedly connected to the mounting base 3, and the other end of the cylinder 93 is slidably installed with The connecting rod 91, the inner cavity of the cylinder body 93 is slidably provided with a plug 92, one end of the connecting rod 91 is fixedly connected with the plug 92, and the other end of the connecting rod 91 is connected with the fence 2 through the elastic cable 10, When working, when the fence 2 is moved by the impact force, the connecting rod 91 drives the block 92 to move together through the elastic cable 10, and at the same time, the air pressure resistance generated inside the cylinder 93 blocks the movement of the block 92 and the impact force received by the fence 2 They conflict with each other, so as to achieve the buffer effect and improve the anti-collision effect of the guardrail.

Abstract

The invention belongs to the technical field of transportation infrastructure, in particular to a highway anti-collision guardrail, which comprises two columns, a fence plate, a mounting seat, triangular columns, a pull rod and connecting plates. The two columns are symmetrically arranged leftwards and rightwards. One sides of the columns are equipped with mounting seats. The upper surfaces at theother ends of the mounting seats are equipped with triangular columns. The fence plate is segmented and connected through connecting springs. One ends of the connecting plates are fixedly connected with the fence plates and the other ends are connected with the triangular columns through installation shafts. Front and back sides of each mounting seat are equipped with the pull rods. The segmentedfence plates connected by the connection springs are utilized. Through elastic deformation, impact force is buffered so that the installation shafts at end heads of the connection plates fall down from the triangular columns of the mounting seats. Therefore, the fence plates do not deform by impact force. Therefore, anti-collision effect of the guardrail is effectively improved. meanwhile, the pull rod is utilized to connect the fence plates. Therefore, the fence plates are prevented from throwing away so that secondary harm is avoided. therefore, safety performance of the guardrail is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of traffic infrastructure, in particular to an anti-collision guardrail for expressways. Background technique [0002] As a basic safety facility on highways, highway crash barriers play a very important role in ensuring traffic safety on high-grade highways. Due to the fast speed and high density of vehicles traveling on high-grade highways, a complete set of safety highway crash barrier facilities is essential for every high-grade highway. He plays a very important role in preventing traffic accidents. Existing highway anti-collision barriers usually use steel plates, which are rigidly connected. When a car loses control and hits the guardrail, it can prevent the car from turning over on both sides of the road or crashing into the opposite lane. However, it has been proved in practice that the rigid connection The guardrail has no cushioning function. Under the high-speed and powerful impact of an out-of...
