Embodiment Construction

[0038] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific embodiments.

[0039] like Figure 1 to Figure 3 As shown, a belt-type flexible energy-absorbing highway guardrail includes a guard column 1, a guard belt 2 and an elastic blocking member 3; both ends of the guard belt 2 are connected to the guard column 1; the guard column 1 is fixed Connected to the prefabricated cement installation pits on both sides of the road; elastic blocking parts 3 are arranged between the protective columns 1; the elastic blocking parts 3 are used to prevent the vehicle causing the accident from crossing the guardrail; wherein,

[0040] The protective column 1 includes a column body 11, a round rod 12, a No. 1 spring 13, a tape reel 14, a sliding block 15, a fixed plate 16 and a guide sleeve 17; the interior of the column body 11 ...

Abstract

The invention belongs to the technical field of highway guardrails, and is specifically a belt-type flexible energy-absorbing highway guardrail, which includes a protective column, a protective belt and an elastic blocking part; is pulled out, and then the protective belt drives the reel to rotate, and then the reel drives the round rod to move downward through the thread, and then the round rod drives the sliding block to slide down, and then the sliding block compresses the No. 1 spring, thereby realizing the power of the vehicle that caused the accident The conversion of potential energy to the elastic potential energy of the No. 1 spring gradually reduces the moving speed of the vehicle causing the accident, thereby reducing the moving distance of the vehicle causing the accident, thereby reducing the scope and loss of the accident; at the same time, it realizes the flexible contact between the vehicle and the guardrail , thereby avoiding the injury to the occupants in the vehicle due to the instantaneous stop of the vehicle causing the accident, thereby reducing the damage to the vehicle and personnel involved in the accident.

Description

technical field [0001] The invention belongs to the technical field of highway guardrails, in particular to a belt-type flexible energy-absorbing highway guardrail. Background technique [0002] Highway guardrail is the main form of semi-rigid guardrail, which is a continuous structure with corrugated steel guardrails spliced ​​to each other and supported by main columns. The role of the vehicle in 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 ​​with each other to protect the vehicles and personnel in the event of an accident, and prevent the vehicles from rushing out of the road and causing greater losses, although they can be absorbed by the deformation of the corrugated steel plates. The energy of the accident vehicle, but the rigid contact bet...
