Description
Technical field
The utility model relates to guardrail, relates in particular to a kind of special-purpose guardrail that is used for emergent mouthful of speedway isolation strip.
Background technology
During present domestic high speed and standard highway are built, need be provided with special-purpose guardrail for emergent mouthful at central partition usually, when traffic accident occurring, offer passage again to satisfy, relieve traffic congestion.
The special-purpose guardrail that the existing highway isolation strip is emergent mouthful, generally adopt following four kinds of structural concepts:
One class is the telescopic movable guardrail, and this type of guardrail has the basic structure of parallelogram, though flexible comparatively flexible, because of lacking the fixedly connected of necessity, thereby its crashworthiness is relatively poor between the stretching structure, and is now superseded substantially.
Second class is the plug-in type guardrail, and this type of guard bar structure is comparatively simple, be made of several bodys that are inserted in the ground subsoils, but crashworthiness is relatively poor, and does not have an anti-theft feature.
The 3rd class is common cement block guardrail, and the emergent mouth that this type of guardrail constitutes is not had a flexibility.If when running into emergency and needing opening, the crane cement block of just moving away to the scene must be arranged, do not meet an emergent mouthful of flexible designing requirement.
The 4th class is crashproof folding guardrail, and the guardrail beam of this type of guardrail adopts square tube, and front-back adopts the two-sided hinge of buckle between the adjacent fence unit, exists following deficiency: 1. crashproof of square tube is the plane, and crashworthiness is poor, even jog also can form depression.2. the two-sided hinge in front and back is opened very trouble, need unload next side hinge, could fold guardrail, poor practicability.3. the fixed end column inserts in the roadbed, for fixed not rotatable, when opening emergent mouthful, reduce emergent mouth and effectively utilizes length.
The utility model content
The utility model provides a kind of folding type movable guardrail, and crashworthiness difference and guardrail that it can solve the prior art existence fold problems such as trouble.
In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is, a kind of folding type movable guardrail, comprise the end column that at least one side end is provided with, several fence units, the front-back of each fence unit are the guardrail beam, connect by hinge between the adjacent fence unit, it is characterized in that adopting between the adjacent fence unit single hinge to connect, and the hinge front-back is crisscross arranged.
In the technical solution of the utility model, also have following technical characterictic: described guardrail beam is wave beams or main spar.
In the technical solution of the utility model, also has following technical characterictic: obstruction block and side obstruction block in each fence unit is provided with, obstruction block and side obstruction block are separately positioned on the two ends of guardrail beam in described, obstruction block is arranged between the guardrail beam of described front and back in described, described side obstruction block is arranged on guardrail beam the other end, described front and back, and described interior obstruction block and obstruction block are fixed with the guardrail beam respectively.
In the technical solution of the utility model, also have following technical characterictic: described end column comprises roadbed pipe, upper and lower flange, end rotation column, described lower flange is fixedly connected on described roadbed pipe upper end, described upper flange is stacked on the described lower flange and interconnects, and described end is rotated column and is inserted in the annulus hole of described upper and lower flange and in the described roadbed pipe.
In the technical solution of the utility model, also have following technical characterictic: the cylinder that column is rotated in described end is provided with a circle annulus, the contact surface of described upper and lower flange and described annulus is formed with groove, and described end active column can rotate around described groove by described annulus.
In the technical solution of the utility model, also have following technical characterictic: the place, annulus hole of described upper and lower flange is formed with bearing support, in the described bearing support bearing is housed, and described end active column can rotate around described bearing.
In the technical solution of the utility model, also have following technical characterictic: described wave beams is selected W shape.
The utility model compared with prior art has the following advantages and good effect:
1. adopt one-sided hinge foldable structure, realize folding flexibly between each joint, folding convenient is time saving and energy saving.
2. the guardrail beam adopts wave beams, W shape for example, and the surface forms height and rises and falls, and crashworthiness significantly improves, and meets the emergent regulation requirement of speedway, and appearance looks elegant.
3. the end column adopts turnably, can rotate guardrail as required, has increased regulatory function, and is convenient and practical.
