Abstract
The utility model relates to a kind of bridge guardrails, including column, first crossbeam, second cross beam, fixing seat and rotor plate；The first crossbeam both ends are fixedly connected on the rotor plate, and the bottom end of the rotor plate is cooperated by grafting pin and the column bottom hinge；Two groups of Buffer Units are vertically equipped with inside the column, the Buffer Unit includes jack, spring part, cushion, inserted link, and the bottom end of the jack is fixed in described spring part one end, and the other end of the spring part is fixedly connected with the cushion；Described inserted link one end is plugged in the jack, and the inserted link other end is fixedly connected on the rotor plate.The utility model has the advantages that after first crossbeam is hit, by the buffer function of cushion, spring part, the impact force of vehicle is greatly reduced, first crossbeam, second cross beam can have the function that stop automobile again later, by three layers of buffering Intercepting effects, the harm of automobile collision accident is substantially reduced.
Description
Technical field
The utility model belongs to Highway bridge technique field, is related to a kind of guardrail, and in particular to a kind of bridge guardrail.
Background technique
Bridge is swept away when to prevent automobile from accident occurs, and anticollision barrier to be usually installed on bridge.Currently, highway in China is more
Using armored concrete wall guardrail and guardrail wires, existing highway bridge guardrail generallys use reinforced concrete anticollision barrier, when
When vehicle unexpected situation occurs and strikes anticollision barrier, due to being mostly to be rigidly connected between guard rail, itself do not have any
Buffer function, after accident, which occurs, for automobile knocks, the impact force of generation is very big, vehicle and the equal well damage of anticollision barrier, very
Certain threat can be extremely brought to the personal safety of occupant.
Further, since inertia is big when vehicle is run, simple stiff safety fence is largely single support rod, is easy by vehicle
It breaks, falls the major accident of bridge.
Utility model content
The problems in background in view of the above technology, the utility model aim are to provide a kind of bridge guardrail, protection effect
It is good, it is highly-safe.
In order to achieve the goal above, the technical solution adopted in the utility model are as follows:
A kind of bridge guardrail, including column, first crossbeam, second cross beam, fixing seat and rotor plate, the column are fixed
On the fixing seat, the first crossbeam and the second cross beam are connected between the adjacent column, and described first is horizontal
Beam is located at the front end of the second cross beam；
The first crossbeam both ends are fixedly connected on the rotor plate, and the bottom end of the rotor plate passes through grafting pin and institute
State the cooperation of column bottom hinge；
Two groups of Buffer Units are vertically equipped with inside the column, the Buffer Unit includes jack, spring part, delays
The bottom end of the jack is fixed in punching pad, inserted link, described spring part one end, and the other end of the spring part and the cushion are solid
Fixed connection；
Described inserted link one end is plugged in the jack, and the inserted link other end is fixedly connected on the rotor plate.
Further, the second cross beam is fixedly connected on the trailing flank of the column.
Further, the first crossbeam is spaced apart with the second cross beam.
Further, the aperture widths of the jack are equal or slightly larger than the width of the inserted link.
The utility model has the technical effect that
Protective fence strong shock resistance in the utility model, when surprisingly occur car hit on guardrail when, first crossbeam by
It drives rotor plate to rotate to column direction after shock, and then pushes inserted link mobile to jack bottom, until rotation plate surface is touched
To leg surface, buffer function of the inserted link by cushion, spring part is then greatly reduced the impact force of vehicle, touches later
Fixed first crossbeam will continue to play the role of stopping vehicle on to the rotor plate of leg surface, reach secondary buffer,
When Vehicular impact power is excessive, even if first crossbeam is damaged, but second cross beam in its back-end can play obstruction automobile again
Effect, by three layers of buffering Intercepting effects, substantially reduces the harm of automobile collision accident.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model protective fence；
Fig. 2 is the cross-sectional view of the utility model protective fence buckstay.
Appended drawing reference: 1- column；2- first crossbeam；3- second cross beam；4- fixing seat；5- rotor plate；6- Buffer Unit；
61- jack；62- spring part；63- cushion；64- inserted link；7- grafting pin.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
Referring to attached drawing 1-2, a kind of bridge guardrail, including column 1, first crossbeam 2, second cross beam 3, fixing seat 4 and turn
Movable plate 5, the column 1 are fixed in the fixing seat 4, which is characterized in that the first crossbeam 2 connects with the second cross beam 3
It connects between the adjacent column 1, the first crossbeam 2 is located at the front end of the second cross beam 3；
2 both ends of first crossbeam are fixedly connected on the rotor plate 5, and the bottom end of the rotor plate 5 passes through grafting pin 7
Cooperate with 1 bottom hinge of column；
Two groups of Buffer Units 6 are vertically equipped with inside the column 1, the Buffer Unit 6 includes jack 61, spring
The bottom end of the jack 61 is fixed in part 62, cushion 63, inserted link 64, described 62 one end of spring part, the spring part 62 it is another
One end is fixedly connected with the cushion 63；
Described 64 one end of inserted link is plugged in the jack 61, and 64 other end of inserted link is fixedly connected on the rotor plate
On 5.
When guardrail on car hit surprisingly occurs, first crossbeam 2 drives rotor plate 5 to turn to 1 direction of column after being hit
It is dynamic, and then push inserted link 64 mobile to 61 bottom of jack, until 5 surface of rotor plate touches 1 surface of column, inserted link 64 is by slow
The buffer function of pad 63, spring part 62 is rushed, the impact force of vehicle is then greatly reduced, touches the rotation on 1 surface of column later
Fixed first crossbeam 2 will continue to play the role of stopping vehicle on plate 5, reach secondary buffer, when Vehicular impact power mistake
When big, even if first crossbeam 2 is damaged, but second cross beam 3 in its back-end can play the role of stopping automobile again, by three layers
Intercepting effects are buffered, the harm of automobile collision accident is substantially reduced.
Further, the second cross beam 3 is fixedly connected on the trailing flank of the column 1.
Further, the first crossbeam 2 is spaced apart with the second cross beam 3.
Further, the aperture widths of the jack 61 are equal or slightly larger than the width of the inserted link 64.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
