Abstract

The utility model discloses a folding movable barrier guardrail which comprises more than two movable guardrails. The movable guardrails are provided with guardrail bodies and are hinged with each other; more than one movable post is fixed on the guardrail bodies; a universal wheel is arranged at the lower part of each movable post; guide pipes or guide holes are arranged on the guardrail bodies; and lifting posts are arranged in the guide pipes or guide holes and can slide up and down in the guide pipes or guide holes, so as to be inserted into or pulled out of corresponding fixed holes formed previously on the ground. The utility model comprises more than two movable guardrails, which are hinged with each other and can be folded and move through the movable posts fixed on the guardrail bodies. Therefore, the movable guardrails can isolate or open openings conveniently and effortlessly. The lifting posts arranged on the guardrail bodies can be inserted into or pulled out of the corresponding fixed holes formed previously on the ground, so as to perform the fixing function. Therefore, the guardrail bodies and the foundation are connected together when being impacted, which greatly enhances impact resistance and prevents vehicles from further rushing into the opposite lane to cause more serious traffic accidents.

Description

Folding movable isolation guardrail

Technical field

The utility model relates to a kind of traffic safety facilities, relates in particular to a kind of isolation guardrail.

Background technology

Isolation guardrail is a kind of road safety facility that in road traffic, is widely used, and is that the warning vehicle that is provided with along the shoulder of Dangerous Area sails out of roadbed and the vehicle that prevents that is provided with along the median strip is swarmed into the protective equipment of subtend roadway, and for making the facility of the guarantee pedestrains safety that pedestrian and vehicle insulation be provided with; Has the sight line of inducing human pilot; Cause that it is vigilant or limit effects such as the pedestrian crosses arbitrarily, at some opening part that is provided with along the median strip, pairs of openings is isolated or open occasion setting as required sometimes; Present interim guardrail adopts some steel frame constructions more; Can not move freely, intensity is not high yet simultaneously, and deadweight is very light; Vehicle one bumps then and knocks away gently, does not reach isolation effect.

Summary of the invention

The problem to be solved of the utility model provides a kind of conveniently moving, the effective folding movable isolation guardrail of impact resistance.

The technical scheme that the utility model adopted is: folding movable isolation guardrail, comprise two above movable rails, and movable rail is provided with the guardrail main body; Be articulated and connected between the movable rail, be fixed with movable post more than on the said guardrail main body, said movable post has universal wheel; Said guardrail main body is provided with guide pipe or pilot hole; Be provided with lifting column in guide pipe or the pilot hole, lifting column can slide up and down in guide pipe or pilot hole, to insert or to pull out the corresponding preset fixing hole in ground.

Preferred said guardrail main body is a rectangle van-type guardrail, also can be through such structures of mode fixed guide pipe such as welding in the middle of the two corrugated guardrail sheets of front and back.

Be articulated and connected through the tubular shaft type hinge between the preferred said movable rail.

Said lifting column is provided with the post lid in order to prop up the location behind the fixing hole that falls into ground at lifting column.

Said lifting column is provided with the handle ring so that lift.

Said lifting column is provided with alignment pin in order to after mentioning the lifting column built on stilts, to locate and to hang on the guardrail main body.

The beneficial effect of the utility model is: the utility model comprises two above movable rails; Can draw in foldingly through being articulated and connected, and move, so mobile protect fence realizes that pairs of openings is isolated or open convenient and strength-saving through movable post fixing on the guardrail main body; The lifting column that the guardrail body is provided with; Can insert or pull out by corresponding preset fixing hole on ground, play fixation, guardrail main body and ground are joined together when being impacted; Can strengthen the impact resistance effect greatly, avoid vehicle further to pour the subtend track and cause bigger traffic accident.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:

Fig. 1 is the structural representation of the folding movable isolation guardrail of the utility model;

Fig. 2 is the lateral view of Fig. 1;

Fig. 3 is the structural representation of the lifting column of the folding movable isolation guardrail of the utility model when mentioning;

Fig. 4 is that the folding movable isolation guardrail of the utility model draws the overall structure vertical view after folding in.

The specific embodiment

Folding movable isolation guardrail in the present embodiment comprises 4 movable rails, in Fig. 1, Fig. 2, is connected to example with two movable rails 1 and describes, and all the other two connected modes are identical; Like Fig. 1, shown in Figure 2, movable rail 1 is provided with guardrail main body 10, is articulated and connected through tubular shaft type hinge 2 between the movable rail 1; Fixing two movable posts 3 on each guardrail main body 10, movable post 3 has universal wheel 31 so that movable rail 1 moves, and guardrail main body 10 is a rectangle van-type guardrail; Two guardrails 11 promptly, between 12, up and down respectively with upper cover plate 13 be connected liner plate 14 and seal and be formed by connecting, casing of formation is also sealed with end-plate 15 in two ends; On the guardrail main body 10 upper cover plate 13 be connected liner plate 14 perforates and form pilot hole 16, be provided with lifting column 4 in the pilot hole 16, lifting column 4 can slide up and down in pilot hole 16; To insert or to pull out the corresponding preset fixing hole 5 in ground; The top is provided with post lid 41 on the lifting column 4, and its diameter props up upper cover plate 13 location greater than pilot hole 16 on the upper cover plate 13 after in order to the fixing hole 5 that falls into ground at lifting column 4, and its underpart is provided with alignment pin 42; On the pilot hole 16 that connects on the liner plate 14, have breach simultaneously to pass through alignment pin 42; After mentioning lifting column 4 built on stilts, after alignment pin 42 passed the breach that connects the pilot hole 16 on the liner plate 14, rotation and lifting post 4 staggered the breach of alignment pin 42 and pilot hole 16 and puts down lifting column 4 after the angle; Alignment pin 42 promptly is stuck in to connect on the liner plate 14 lifting column 4 is hung on the guardrail main body 10; Be illustrated in figure 3 as the structural representation after lifting column 4 is mentioned,, also be provided with handle 43 on the post lid 41 for conveniently mentioning.

In the time need not using folding movable isolation guardrail, through lifting column 4 is mentioned, each movable rail 1 moves folding each other closing up along tubular shaft type hinge 2 and through 3 times universal wheel 31 push-and-pulls of movable post then, draws at last to be state as shown in Figure 4.
