Description
Technical field
The utility model relates to a kind of traffic safety facilities, and particularly one is detachable, the movable anticollision barrier of movement.
Background technology
At present, movable rail China's speedway generally adopted has plug-in, plug-type and filling type three kinds.These three kinds of movable rail ratios are easier to open and mobile, but all there is the defects such as do not possess protective capacities or protective capacities is not enough, once errant vehicle collision must be passed through and pour subtend track, bring out the generation of secondary collision accident.The Novel chain type concrete anti-collision guard bar of exploitation in nearly 2 years, although its barrier propterty meets the demands, is also convenient to dismounting, and the mobile of its concrete block needs mechanical handling, very inconvenient.These guardrails all can not meet the instructions for use required for Expressway Central Strip opening part movable rail comprehensively above, namely median opening movable rail has certain isolation, crashworthiness under normal circumstances, should be able to move fast, neatly when interim opening.So the traffic safety of vehicle and the speed of rescue all can be affected.
Summary of the invention
The utility model provides a kind of structure simply, both to have isolation, crashworthiness for solving in known technology the technical problem that exists, has again for convenience detach, can the fast and flexible ground movable anticollision barrier of travelling performance.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of movable anticollision barrier, this protects movable hurdle and links together by several fence unit is detachable, it is characterized in that: described fence unit comprises guardrail body, described guardrail body is formed by concreting, described guardrail body is vertically arranged with internal thread sleeve pipe, equipped elevating screw in described internal thread sleeve pipe, described elevating screw distance threaded sleeve upper surface certain distance, it is made to be hidden in threaded sleeve, the upper end fitting operation handle of described elevating screw, the upper surface of described operating grip lower surface and elevating screw is provided with the bite cooperatively interacted, the soffit of described guardrail body is provided with trapezoidal notch, and in described trapezoidal notch, the lower end of elevating screw is flexibly connected triangle mobile roof support, the lower end floor beam both sides installed rows travelling wheel respectively of described triangle mobile roof support, the both ends of the surface of described fence unit are provided with the connecting portion be connected with adjacent fence unit.
The utility model can also adopt following technical measures:
Described connecting portion for connecting seam and be connected boss, described connection boss be connected seam shape size and mate; The seam of adjacent fence unit coordinates with the boss of adjacent fence unit.
Described connecting portion is T-shaped link slot, and the T-shaped link slot of adjacent fence unit is corresponding, encloses an I-shaped link slot, equipped I shape connector in I-shaped link slot.
Described bite comprises occlusion protuberance and occlusion recess, and described occlusion protuberance and occlusion recess correspondence are arranged on elevating screw and operating grip end.
The advantage that the utility model has and good effect are: concrete guardrail strong for barrier propterty is divided into several fence units; be connected to form the form of structure of a chain by dismountable syndeton between each section; each section concrete block lifts away from ground by elevating screw; the gravity of concrete block born by mobile roof support and elevating screw, thus reach object that is quick, movement flexibly.
