SUMMERY OF THE UTILITY MODEL
The utility model aims to solve among the prior art anticollision barrier can't be adjusted the height wantonly, need install new hole site again when the height-adjusting, waste time and energy, problem such as with high costs provides a liftable highway anticollision barrier, can realize the arbitrary regulation of guardrail height through swivel connected coupler, makes it can maintain best anticollision height in real time, and the design of fixture block makes the rotation of connecting piece easier, convenient and fast, and it is laborsaving to save trouble, simple structure, and the construction is swift.
In order to realize the purpose of the utility model, the utility model provides a following technical scheme:
a liftable highway anti-collision guardrail comprises a plurality of upright columns arranged on the ground and a guardrail plate fixed between the upright columns, wherein each upright column comprises a base, a column body and a connecting piece; the top of the base is provided with a first threaded connecting hole, the lower end of the connecting piece is provided with a first screw matched with the first threaded connecting hole, the bottom of the upright post is provided with a second threaded connecting hole, the upper end of the connecting piece is provided with a second screw matched with the second threaded connecting hole, the first screw and the second screw are coaxially arranged and have opposite thread directions, and the middle of the connecting piece is provided with a clamping block for clamping a wrench or a pipe wrench;
and the upright post is provided with a mounting structure for fixing the guardrail plate.
The utility model provides a highway anticollision barrier when the installation, the connecting piece insert through first screw rod in the first threaded connection hole with pedestal connection, insert through the second screw rod in the second threaded connection hole with the cylinder be connected. When the height of the guardrail needs to be adjusted, the first screw rod is gradually screwed out from the first threaded connecting hole only through the fixture block rotating connecting piece, meanwhile, the second screw rod is gradually screwed out from the second threaded connecting hole, and when the column body reaches the designated height, the rotation is stopped.
Further, the mounting structure is a mounting hole or a mounting groove.
Further, the guardrail plate is a wave-shaped guardrail plate.
Further, the shape of the base is a cylinder or a prism or a special-shaped structure.
Further, the shape of the cylinder is a cylinder, a triangular prism or a quadrangular prism.
Furthermore, a gap is formed at the joint of the guardrail plate and the upright column, the gap is 0.5cm-2cm, and the gap at the joint can reduce the resistance of the guardrail plate to the upright column when the upright column is lifted or lowered, so that the upright column is more convenient to lift or lower.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model provides a stand of highway anticollision barrier includes base, cylinder and connecting piece, and the first screw rod of connecting piece and the first threaded connection hole threaded connection of base, the second screw rod and the second threaded connection hole threaded connection of cylinder can realize the arbitrary regulation of guardrail height through rotatory connecting piece, make it can maintain best anticollision height in real time, and the rotation of connecting piece is made easier by the design of fixture block; and when going up and down, need not to demolish anticollision barrier from former hole site, convenient and fast, it is laborsaving to save trouble. The utility model discloses a highway crash barrier simple structure, the construction is swift, convenient, and easy maintenance is changed.
