Safety telescopic guardrail

Abstract

The invention relates to a safety telescopic guardrail, and belongs to the technical field of traffic facilities. The safety telescopic guardrail comprises an end road barrier, a primary road barrier, multiple secondary road barriers, telescopic parts, connecting parts and cross rods. The telescopic parts are formed by connecting the first telescopic parts and the second telescopic parts which can be dislocated, one end of each first telescopic part is connected with the end road barrier, the other ends of the first telescopic parts are connected with the second telescopic parts through the primary road barrier, and the second telescopic parts penetrate into the adjacent secondary road barrier of the primary road barrier. The adjacent secondary road barriers are connected through the cross rods, the cross rods are composed of the first cross rods and the second cross rods, and the first cross rods and the second cross rods are connected through the connecting parts. The safety telescopic guardrail is used for guardrail connection on occasions such as expressways and city highways, and has the advantages of being high in practicality and safety, capable of being bent and adjusting the distance and the like.

Description

Technical field [0001] The invention relates to a safety telescopic guardrail, which belongs to the technical field of transportation equipment. Background technique [0002] At present, guardrails are mainly used to isolate vehicles and vehicles, vehicles and pedestrians, so that vehicles and vehicles, vehicles and pedestrians can go on their own paths and pass smoothly. Guardrails are mainly set up on highways, urban roads, busy traffic areas, toll stations, Parking lots, residential areas, etc., and when installing guardrails, they are also subject to restrictions such as road bends, unevenness, bridges, and crossbars. At present, the guardrail on the road is usually made up of several isolation piers in series. The adjacent isolation piers are connected in rigid continuous or rigid intermittent series. When the existing guardrail is impacted by external forces such as traffic accidents, due to the isolation piers A rigid and continuous connection is used between the crossbar...

AI Technical Summary

Problems solved by technology

At present, the guardrails on the road are usually composed of several isolation piers connected in series, and the adjacent isolation piers are rigidly connected continuously or intermittently connected by crossbars. When the existing guardrail is impacted by external forces such as traffic accidents, due The cross-bars connected in series between the cross-bars are connected rigidly and continuously so as to lose the cushioning of the impact force. After damage, the damaged parts cannot be replaced flexibly. Moreover, when the existing guardrails are installed, they will be affected by the surrounding environment and the guardrails will disappear at any time. , The connection and series connection between the crossbars are restricted, so the guardrails cannot be set and installed according to the high superiority, safety requirements and scientific rationality of the guardrails. When the existing guardrails are impacted by external forces such as vehicles, it can cause a large number of The isolation pier and crossbar are broken and splashed, the crossbar breaks away from the puncture vehicle, endangers the safety of personnel and other serious consequences. In short, the crossbar connection in the existing traffic guardrail can no longer meet the requirements of modern guardrail installation for safety and flexibility.
