Abstract
Buffer of traffic road surface facility end crashproof on the concrete structure of the traffic road surface facility end body, has connecting plate and a turn -up drum with the screwed connection that expands there is the sealing washer between, inner chamber at the turn -up drum has the piston, has 2 -3 to say on its circumference and has a 2 -5 fore -and -aft backward flow hole by the sealing ring on its cylinder. There is compression spring in the piston inboard. Outer thread to match on there are nut and turn -up drum in the outer end of turn -up drum closes. Inner chamber full of liquid at the turn -up drum. Be connected with the tappet in piston cylindrical outer end, outside the tappet stretched out turn -up drum and nut, the threaded nut of outer end head of tappet was connected on the connecting plate, by for board screw connection of two tappets and connecting plate and striking. The bracing piece supports subaerial for the buffer. When taking place the striking, the striking board passes through the tappet makes the piston move to the inboard, compression compression spring, and simultaneously, flowing to turn -up drum outside inner chamber in the fluid passage backward flow hole of the inboard inner chamber of turn -up drum, has played the cushioning effect.
Description
Technical field
This utility model relates to the buffer unit of traffic facility termination anticollision。
Background technology
In the termination of traffic facility, being exposed to traffic main artery, seething vehicle is likely knocked, and causes the vehicle accident of car crash。Present case is, in the termination of traffic facility, all without arranging the buffer unit that collision prevention of vehicle hits, vehicle accident happens occasionally, and causes the injury to personnel and the damage to vehicle。
Utility model content
The purpose of this utility model is to provide the buffer unit of traffic facility termination anticollision to overcome above-mentioned weak point, and alleviate or avoid traffic accident the injury to personnel and the damage to vehicle。
This utility model solves its technical problem and be the technical scheme is that on the concrete body of traffic facility termination, it is connected to connecting plate with setscrew, also have crimping cylinder with what setscrew was simultaneously connected with, between connecting plate and crimping cylinder, have sealing ring。Crimping cylinder adopts metal manufacture。Inner chamber at crimping cylinder has piston, on the circumference of piston, has 2-3 road sealing ring, on the cylinder of piston, has 2-5 longitudinal return port。There is compression spring in the inboard of piston, be inboard near the side of facility termination。There is nut in the outer end of crimping cylinder, and the external screw thread on crimping cylinder matches, between the outer face and nut of crimping cylinder, have sealing ring。Hydraulically full at the inner chamber of crimping cylinder。Being connected to tappet in the outer end of piston cylinder, the inner end of tappet has spherical, pressing plate and screw fix。Tappet stretches out outside crimping cylinder and nut, and the outer end head of tappet has screw nut to be connected on connecting plate, two tappets and connecting plate thereof and crash panel screw connect。The outside of crash panel has arc, to alleviate shock。Whole buffer unit they sup-port on the ground, is highly 400-800 millimeter。When there is accidental impact, crash panel makes piston run to inboard by tappet, compression compression spring, simultaneously, the liquid of crimping cylinder inboard inner chamber by return port to inner chamber flowing outside crimping cylinder, having played cushioning effect, alleviate or avoid traffic accident the injury to personnel and the damage to vehicle。
Effective effect of the present utility model is, applies the buffer unit of traffic facility termination anticollision of the present utility model, and alleviate or avoid traffic accident the injury to personnel and the damage to vehicle。
