Embodiment Construction
[0038] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0039] Such as Figure 1 to Figure 3 As shown, a belt-type flexible energy-absorbing highway guardrail includes a protective column 1, a protective belt 2 and an elastic blocking member 3; both ends of the protective belt 2 are connected to the protective column 1; the protective column 1 is fixed It is connected to the prefabricated cement installation pits on both sides of the road; elastic blocking parts 3 are arranged between the prevention columns; the elastic blocking parts 3 are used to prevent the accident vehicle from crossing the guardrail; wherein,
[0040] The protective column 1 includes a column 11, a round rod 12, a spring 13, a reel 14, a sliding block 15, a fixed plate 16 and a guide sleeve 17; the inside of the column 11 is a cav...

The invention belongs to the technical field of highway guardrails, and particularly relates to a belt type flexible energy absorption highway guardrail. The highway guardrail comprises protective stand columns, a protective belt and an elastic blocking component. A hit-and-run vehicle drives the protective belt to move towards the outer side of a road, then the protective belt is pulled out, thenthe protective belt drives a belt winding barrel to rotate, the belt winding barrel drives a round rod to move downwards through threads, then the round rod drives a sliding block to slide downwards,then the sliding block compresses a first spring, the power potential energy of the hit-and-run vehicle is converted into the elastic potential energy of the first spring, the moving speed of the hit-and-run vehicle is gradually reduced, and the moving distance of the hit-and-run vehicle is reduced, so the accident swept range and loss are reduced. Meanwhile, flexible contact between the vehicleand the guardrail is achieved, damage to personnel in the vehicle due to instant stop of the hit-and-run vehicle is avoided, and damage to the hit-and-run vehicle and the personnel is reduced.
Description
technical field [0001] The invention belongs to the technical field of road guardrails, in particular to a belt-type flexible energy-absorbing road guardrail. Background technique [0002] Highway guardrail is the main form of semi-rigid guardrail, which is a continuous structure that is spliced with corrugated steel guardrail panels and supported by main columns. The effect of the vehicle on absorbing energy when it collides is not easy to be crashed, and at the same time it can play a very good role in protecting the vehicle and the driver and passengers. [0003] The existing guardrails on the side of the road are mainly made of corrugated steel plates spliced together to protect the vehicles and personnel involved in accidents and prevent the vehicles from rushing out of the road to cause greater losses. Although it can be absorbed by the deformation of corrugated steel plates However, if the corrugated steel plate is in rigid contact with the vehicle causing the ac...
