Deceleration energy dissipation parking system, avoidance lane and deceleration energy dissipation parking method

Abstract

The invention discloses a , wherein the system comprises a foundation pit, a first steel plate, a first high strength support spring, a second steel plate and a second high strength support spring; the foundation pit is provided with a first side wall and a second side wall; the first side wall is positioned at the front of the second side wall; the first steel plate can wiggle on the first side wall; one end of the first high strength is connected to the bottom surface of the foundation pit and the other end is connected with the free end of the first steel plate; the second steel plate can wiggle on the second side wall; one end of the second high strength is connected to the bottom surface of the foundation pit and the other end is connected with the free end of the second steel plate; after the first steel plate is pressed by wheels of a danger escaping vehicle, the first steel plate is unset by elasticity; and meanwhile, the wheels press the second steel plate and can be clamped in a steel plate clamping groove formed by the first steel plate and the second steel plate. Through adoption of the deceleration energy dissipation parking system, the truck escape ramp and the deceleration energy dissipation parking method provided by the invention, a vehicle out of control is subjected to deceleration, energy dissipation and parking and can escape from a danger efficiently.

Description

technical field [0001] The invention relates to the technical field of highway avoidance lanes, in particular to a deceleration energy dissipation parking system, an escape lane and a deceleration energy dissipation parking method. Background technique [0002] Restricted by the actual natural and geographical conditions, roads in mountainous and hilly areas, especially expressways, often have low technical indicators, and long steep slopes and sharp turns on steep slopes are more common. Vehicles driving downhill on these roads for a long time and using the brakes frequently will cause the temperature of the brake hub to rise rapidly, which can reach more than 300°C. The temperature of the brake hub rises to high temperature frequently, which is very prone to carbonization, resulting in brake failure. On the other hand, when the driver is not familiar with the terrain and the speed of the vehicle is fast, he will often rush out of the road at sharp turns, resulting in serio...

Problems solved by technology

However, in order to enable high-speed vehicles to stop on the avoidance lane relying on the rolling resistance of the wheels, it is generally necessary to set up a 50-100-meter-long escape lane. However, the terrain conditions in mountainous areas are poor, and it is usually difficult to set up an avoidance lane of sufficient length. Therefore, some technicians in the industry set up some anti-collision and energy dissipation facilities on the avoidance lane to help the vehicle slow down and park. Install anti-collision sand buckets and other facilities at the end, but according to actual experience, this method of setting anti-collision facilities makes the avoidance lane that does not reach the required length due to terrain reasons be further shortened because of the installation of anti-collision energy dissipation facilities , and even artificially shorten the length of the escape lane because of the installation of anti-collision energy dissipation facilities, which is very detrimental to the energy dissipation and avoidance of out-of-control vehicles, and cannot effectively guarantee the personal safety of drivers and passengers
