Description

Suspension drum type anti-collision device

Technical Field

The utility model relates to a traffic guardrail technical field, concretely relates to hang drum-type buffer stop.

Background

In highway safety installations, crash barriers have been "commissioned" primarily to prevent vehicles from going out of the road and crossing center dividers, thereby reducing the severity of accidents. At present the most common guardrail on highway is the wave form guardrail, and its continuous beam column structure that constitutes for the wave form line form steel sheet and the stand of mutual concatenation, the primary function includes: (1) when the vehicle is out of control, the waveform guardrail arranged in the middle of the road can effectively prevent the out of control vehicle from entering the opposite lane to cause secondary collision. (2) When the vehicle impacts the wave-shaped guardrail plate, the vehicle can be decelerated and stopped through the deformation of the guardrail, and can also be smoothly transited to drive back to a normal line, so that the injury to a driver caused by the impact is relieved. (3) The road edge line can be seen clearly by a driver, and the driver can distinguish the trend of the road under the conditions of severe natural environments such as night, rainy days, snowy days and the like. (4) When the road surface maintenance or other reasons need to be combined, the guardrail upright post can be conveniently pulled out and moved away, a channel is opened up, and the vehicle can conveniently pass.

However, as the living standard of people increases, the population density increases, and the traffic density of the expressway is increasing. Uncertainty in various driving factors leads to an increased probability of highway traffic accidents. Although the corrugated guardrail can promote the out-of-control vehicle to change the direction, the deformation capability and the energy absorption capability of the corrugated guardrail plate are limited, severe impact friction between the corrugated guardrail plate which is seriously collided and deformed and the automobile can cause the vehicle to break through the steel plate and fire, even the corrugated steel is inserted into the vehicle, even the corrugated steel is inserted into an oil tank to cause the condition of explosion and fire, and more serious casualty accidents are caused. In addition, the fixed end of the existing anti-collision guardrail is not specially processed, so that the hidden danger that high-speed accident vehicles cannot be blocked exists, and when the accident vehicles slide to the fixed end along the movable guardrail, the accident vehicles often trip and block, so that the vehicles stop suddenly or turn or even turn over, and serious traffic accidents occur.

The prior or published roller type protective guards for the expressway are roughly provided with the following types: (1) the roller type guardrail has the advantage of converting sliding friction into rolling friction, but in the prior art, a roller is directly arranged on a pillar fixed on the ground to form a cantilever beam structure, the structural strength of the whole traffic guardrail is not high, the reliability is low, and the whole structure is likely to fail when large impact force is met. (2) The sleeve type anti-collision guardrail is similar to a roller type anti-collision guardrail in appearance and made of soft materials, can greatly buffer the impact force of vehicle collision, but still has the risk of fire due to incapability of rotating. (3) The combined type anti-collision structure has the appearance similar to that of a roller, and the rear part of the combined type anti-collision structure is provided with a triangular bracket which is specially responsible for supporting. The products also have a common defect that the existing waveform guardrail needs to be replaced and the foundation needs to be poured again when the roller type guardrail is installed or modified, so that the construction is very troublesome, a large amount of manpower and material resources are consumed, and the method is not economical.
