Safety height-limiting device for city road

Abstract

The invention provides a safety height-limiting device for a city road. The safety height-limiting device comprises two vertical columns fixed to the road and further comprises a roadblock box body, height-limiting rods used for height limiting are arranged on the upper portions of the vertical columns, and a plurality of through holes are formed in the upper surface of the roadblock box body. A telescopic roadblock rod is arranged in each through hole, a driving mechanism for driving the roadblock rods to stretch out and draw back is arranged in the roadblock box body, and a supporting plateis arranged at the top of each vertical column. The height-limiting rods are slidably mounted on the upper portions of the supporting plates, one ends of the height-limiting rods are connected with achain, and the other end of the chain is connected with the driving mechanism. The safety height-limiting device has the advantages that pure mechanized design is adopted, the structure is simple, maintenance is avoided, and travelling and road safety can be effectively ensured.

Description

technical field [0001] The invention mainly relates to the technical field related to civil engineering, in particular to a safety height limiting device for urban roads. Background technique [0002] The height limit device is installed on urban roads, mainly used to protect roads, bridges, etc., to prevent vehicles that are too high from entering the height limit section. The height limiting device of the traditional structure generally adopts two columns and one height limiting rod to form a gantry frame structure, and the columns are buried in the ground or fixed on the ground to realize the height limit of the vehicle. The use of traditional height-limiting devices is easy to cause accidents. When the driver does not notice the height-limiting device or estimates the height of the height-limiting pole or the height of the vehicle incorrectly, it will easily lead to the collapse and tilt of the column and the height-limiting pole, which will easily cause traffic accident...

Problems solved by technology

The use of traditional height-limiting devices is easy to cause accidents. When the driver does not notice the height-limiting device or estimates the height of the height-limiting pole or the height of the vehicle incorrectly, it will easily lead to the collapse and tilt of the column and the height-limiting pole, which will easily cause traffic accidents

[0003] In order to solve the above problems, there are still some height-limiting devices that can play a certain warning role in the prior art. The warning structures mainly include several forms such as ringing, sounding, and lighti
