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.

Embodiment 1

[0033] The telescopic guardrail of this embodiment combines figure 1 , figure 2 and image 3, including an end isolation pier 1, a first isolation pier 2, several secondary isolation piers 3, an expansion piece 4, a connecting piece 8 and a cross bar 9, and the expansion piece 4 is connected by an expansion piece 1 41 and a expansion piece 2 42 that can move in dislocation One end of the expansion piece 41 is connected to the end isolation pier 1, and the other end passes through the first isolation pier 2 to connect with the expansion piece two 42, and the expansion piece two 42 is installed on the secondary isolation pier adjacent to the first isolation pier 2 In one 31; the second isolation pier 31, the second isolation pier 32 and the second isolation pier three 33 are connected by cross bar 9, and cross bar 9 is made of cross bar one 91 and cross bar two 92, and the second isolation pier two 32 after the secondary isolation pier (between the secondary isolation pier 2 ...

Embodiment 2

[0037] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference is that the first telescopic part 41 and the second telescopic part 42 are tubular structures, and the pipe diameter of the first telescopic part 41 is larger than the pipe diameter of the second telescopic part 42. The second telescopic part 42 is set in the first telescopic part 41, and the first telescopic part 41 can slide along the outer wall of the second telescopic part 42, so as to realize the relative dislocation movement between the first telescopic part 41 and the second telescopic part 42.

Embodiment 3

[0039] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference is that the first telescopic part 41 and the second telescopic part 42 are tubular structures, and the pipe diameter of the first telescopic part 41 is larger than the pipe diameter of the second telescopic part 42. The second 42 is set in the first expansion piece 41, and the first expansion piece 41 can slide along the outer wall of the second expansion piece 42, so as to realize the relative dislocation movement between the first expansion piece 41 and the second expansion piece 42; on the outside of the end isolation pier 1 A warning device 7 is provided, and the warning device is installed on the end isolation pier 1 with a tubular structure. At night or when the light is poor, it plays a role in warning and reminding the vehicles coming from a distance, so as to avoid the driver not seeing The collision caused by clearing the end isolation pier; when the extern...

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 traffic 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 their own way and pass smoothly. Guardrails are mainly installed on highways, urban roads, heavy traffic areas, toll stations, Parking lots, residential areas, etc., and when installing guardrails, it is also subject to constraints such as road curvature, unevenness, bridges, and crossbar lengths. 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 cros...
