Two-section type lifting deceleration strip

Abstract

The invention discloses a two-section type lifting deceleration strip which comprises a front end, a rear end and an embedded column, starting mechanisms are arranged in the front end and the rear end correspondingly, the upper end of the embedded column is connected with the rear end through a reset spring, and a sliding rod connected with the inner wall of the embedded column in a sealed and sliding mode is fixed to the bottom of the rear end; a push plate connected with the inner wall of the embedded column in a sealed and sliding mode is fixed to the bottom of the sliding rod, a spacer ring is fixed to the inner wall of the embedded column, and a push-back mechanism is arranged at the bottom of the embedded column. The two-section type lifting deceleration strip has the advantages that the electrorheological fluid is arranged and can be solidified and expanded after being electrified to support the sliding rod, then the rear end can be effectively manufactured, height adjustment can be easily controlled by controlling the loss amount of the electrorheological fluid, overall control is relatively stable and simple, mechanical damage is not likely to happen, the service life is relatively long, the response speed is very high, and a good lifting function can be achieved.

Description

technical field [0001] The invention relates to the technical field of road facilities, in particular to a two-stage lifting deceleration belt. Background technique [0002] Traffic speed bumps, also called speed bumps, are traffic facilities installed on highways to slow down passing vehicles. Generally, yellow and black are alternated to attract visual attention, and the road surface is slightly arched to achieve the purpose of vehicle deceleration. It is generally set at highway crossings, industrial and mining enterprises, schools, residential quarters, etc., where vehicles need to slow down and where traffic accidents are likely to occur. It is a new type of special traffic safety setting for reducing the speed of motor vehicles and non-motor vehicles; [0003] The existence of the deceleration belt will inevitably cause the vehicle to bump, and then achieve the deceleration effect. However, the height of the existing deceleration belt cannot be changed, and vehicles o...
