A buffer energy dissipation anti-collision barrel for roads

Abstract

The invention provides a buffering energy dissipation anti-collision barrel used for a road and belongs to the field of road traffic safety facilities. The anti-collision barrel comprises a barrel body and barrel pressing sand. The barrel body is an integrated barrel body composed of a semicircular barrel head, a rectangular barrel tail and a sleeve type telescopic rectangular barrel body connected between the barrel head and the barrel tail through a front partition plate and a back partition plate. The barrel head is provided with energy dissipation elastomers and a supporting partition plate. A middle partition plate is arranged between a front barrel body and a back barrel body of the sleeve type telescopic rectangular barrel body. Elastic telescopic energy dissipation devices are positioned to penetrate through the middle partition plate and are connected between the front partition plate and the back partition plate of the telescopic rectangular barrel body. When the barrel body is subjected to exogenic action, the sleeve type telescopic rectangular barrel body compresses the elastomers of the elastic telescopic energy dissipation devices to be contracted through the elastic telescopic energy dissipation devices arranged inside the sleeve type telescopic rectangular barrel body, is backwards compressed along with the elastomers and gradually sleeved outside the back barrel body, so that the buffering impact force is absorbed, the loss caused by impact accidents is reduced, and after the impact force disappears, the barrel body gradually returns to the original state under the action of the elastic telescopic energy dissipation devices.

Description

technical field [0001] The invention relates to a buffer energy dissipation anti-collision barrel for roads, which belongs to the field of road traffic safety facilities. Background technique [0002] With the gradual improvement of vehicle performance, the increase of car ownership year by year, the driving level of drivers is uneven, traffic accidents often occur, especially at road turns, entrances and exits of upper and lower bridges, tunnel entrances, toll islands, bridges In places where traffic collision accidents are more likely to occur, such as the end of the guardrail and the pier of the overspan bridge, the traffic accident rate does have an increasing trend; according to the requirements of relevant national regulations, not only higher requirements are placed on the performance of traffic safety facilities, Where traffic collision accidents are prone to occur, special warning anti-collision facilities, such as anti-collision barrels, etc., should be set up to p...

Problems solved by technology

[0003] At present, road anti-collision buckets mainly adopt two types: bucket type and ship type, which are produced by integral molds. Water or sand is poured into the bucket on site to buffer the impact of vehicles.
