Highway height-limiting obstructing device

Abstract

The invention discloses a highway height-limiting obstructing device. The highway height-limiting obstructing device comprises four supporting columns arranged on the basic ground surface on the two sides of a roadway, obstructing buffer plates are arranged on the outer sides of the upper parts between each two supporting columns on the same side through blots sleeved with compressed springs, installing discs are arranged on the upper parts of each two supporting columns on the same side, and hollow bases are arranged on the middle parts between each two supporting columns on the same side; rotating column bodies are arranged in hollow cavity bodies of the bases, and the upper surfaces of the rotating column bodies are flush with the bottoms of the installing discs; column bodies with through grooves are arranged on the upper parts of the installing discs, two ends of a chain are correspondingly connected to the inner parts of the through grooves of the column bodies in a buckled mode,and pressing discs are arranged on the upper part of the chain; fastening bolts correspondingly penetrate through the centers of the pressing discs, shaft holes of the chain and the centers of the installing discs and then are connected to the axis centers of the rotating column bodies in a threaded mode; and arc-shaped raised blocks are arranged on the side walls of the rotating column bodies. By adopting the structure, the effects that the property loss is reduced and the personnel security is ensured are realized.

Description

technical field [0001] The invention relates to a highway height limiting blocking device. Background technique [0002] At present, height-limiting poles are often used on roads. Due to the difference in height of the height-limiting poles on different roads, some careless drivers often bump into the height-limiting poles. Because most of the height-limiting poles are welded with steel pipes or square steel. As a result, when the vehicle encounters the above-mentioned height limit pole, it will not only cause damage to property, but also bring hidden dangers to people's life safety. Contents of the invention [0003] The purpose of the present invention is to provide a highway height limit blocking device with simple structure, which can reduce property loss as much as possible and ensure personnel safety. [0004] The technical solution of the present invention is a highway height limit blocking device, which is characterized in that it includes four support columns 1 a...
