A deceleration device for road construction

Abstract

The invention provides a deceleration device for road construction, which includes a movable outer deceleration belt for vehicle deceleration, a fixed inner deceleration belt for rigid support, and an extended forced landing mechanism for continuous forced landing of the vehicle. The material of the outer deceleration belt includes rubber, the surface of the movable outer deceleration belt is inclined, the surface of the movable outer deceleration belt is fixedly connected with the surface of the fixed inner deceleration belt, and relates to the field of road construction. According to the problem that the deceleration belt is difficult to continuously decelerate the vehicle on the downhill road, the deceleration device for road construction has designed a special structure that can stretch itself during the vehicle's driving process and can continuously decelerate the vehicle, thus effectively solving the general deceleration. The deceleration area of ​​the belt is relatively limited. In some downhill key construction sections, a large number of fixed deceleration belts are often set up for use, which not only affects the cost of road construction, but also brings great harm to the passing non-motor vehicles to a certain extent. The problem of inconvenience.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a speed reduction device for road construction. Background technique [0002] When constructing roads, it is often necessary to use a deceleration device to limit the speed of the vehicle, and then reduce the safety hazard by reducing the speed of the vehicle, and then the deceleration device that is often used on the road is mainly a deceleration belt. , through the bumping effect of the speed bump, the vehicle is forced to actively reduce the speed of the vehicle, but for the deceleration of the vehicle on the downhill section, the vehicle speed is generally faster, and the deceleration effect of the speed bump is not obvious. Increasing the height of the speed bump will easily increase the safety hazard of the vehicle. The main way is to set up a number of speed bumps distributed at close distances at key intersections. This arrangement not only increases the cost of...
