A self-adaptive lifting deceleration belt

Abstract

The invention discloses an adaptive lifting deceleration belt, which includes a speed measuring plate, a sliding rod, a force transmission spring, a one-way damper, a slide valve, a lock, a lock sliding rod, a pressure spring, a wedge block, a lower piston rod, and a cylinder. body, piston return spring, piston, check valve, upper piston rod, and blocking plate. The speed of the vehicle is reflected in the length of time that the speed measuring board is pressed by the wheels on the road. When the speed measuring plate is pressed on the road surface by the wheel, under the action of the force transmission spring, due to the existence of damping, if the vehicle speed is lower than a certain set value, the action time will be long. When the speed is higher than a certain set value, the action time is short, the slide valve cannot be opened, the lower chamber and the upper chamber of the cylinder are not connected, and the hindrance plate cannot be pressed down when the wheels pass by, thus Impedes the vehicle causing it to jolt. It is beneficial to promote low-speed traffic of vehicles and improve road traffic safety.

Description

technical field [0001] The invention relates to a deceleration belt for roads, in particular to a speed-adaptive lifting deceleration belt. Background technique [0002] The speed bump is a road traffic safety facility, which is generally installed at road crossings, industrial and mining enterprises, schools, and residential quarters to limit the speed of vehicles and ensure the safety of vehicles and pedestrians. The application of speed bumps has greatly reduced the number of traffic accidents and is a very important traffic safety facility. At present, the speed bumps widely used are made of hard rubber, and their convex state cannot be changed. Overspeeding vehicles and low-speed vehicles will cause bumps when passing, causing discomfort to drivers and passengers and damage to vehicles. This is unfair to drivers and vehicles that slow down and slow down in advance according to traffic rules, and is not conducive to promoting the behavior of vehicles to slow down and sl...

Problems solved by technology

At present, the widely used speed bumps are made of hard rubber, and their raised state cannot be changed. Overspeeding vehicles and low-speed vehicles will cause bumps when passing, causing discomfort to drivers and passengers and damage to vehicles.

This is unfair to the drivers and vehicles who obey the traffic rules and slow down in advance, and is not conducive to the behavior of promoting vehicles to slow down

Patent CN207700082U discloses a traffic intelligent deceleration belt device. The minimum vehicle speed is limited by the speed limiting mechanism. When the vehicle is high-speed, the rubber block of the deceleration mechanism has a blocking effect, but when the vehicle is low-speed, the rubber block is flat and does not act as an obstacle. The disadvantage of this device The reason is that when high and low speed vehicles pass by, the rubber block may be lifted up, so it is not stable enough; the patent CN103590348A proposes a hydraulically driven lifting deceleration belt, the main components are the reversing valve and the hydraulic cylinder, and the wheels are first pressed down to change the speed. The directional valve makes the oil pressure pipeline change direction, and then the spool of the hydraulic cylinder is driven downward by the hydraulic oil, driving the bump of the deceleration belt down to the level position of the road surface. The main problem to be solved is to prevent the vehicle from passing Bumping, while high-speed and low-speed vehicles have the same effect, and additional hydraulic oil is required, and there is no solution to intelligently distinguish between high-speed vehicles bumping and low-speed vehicles passing smoothly
