Specific embodiment
The application is described in further detail with reference to the accompanying drawing, it is necessary to it is indicated herein to be, implement in detail below
Mode is served only for that the application is further detailed, and should not be understood as the limitation to the application protection scope, the field
Technical staff can make some nonessential modifications and adaptations to the application according to above-mentioned application content.
In conjunction with shown in Fig. 1 to Fig. 4, a kind of road vehicle crash bearer with pooling feature, by crash bearer ontology 1 and pre-buried peace
Arrangement composition, pre-buried mounting assembly includes pedestal 2, movable plate 3, guide rod 4 and buffer spring 5, is provided with rectangle on pedestal 2
Slot 6, and mounting blocks 7 are respectively equipped at the both ends of rectangular channel 6, guide rod 4 has several, and general no less than 4, guide rod 4 is simultaneously
Framed bent is located between two mounting blocks 7, is provided on movable plate 3 and is passed through through-hole with the one-to-one through-hole of guide rod 4, movable plate 3
It is movably connected on guide rod 4, the one-to-one correspondence of buffer spring 5 covers on guide rod 4, and all buffer springs 5 are located at movable plate 3
The same side, the bottom of crash bearer ontology 1 is fixedly mounted on 3 upper surface of movable plate；
The width of movable plate 3 is equal to the width of rectangular channel 6, several installations are uniformly provided on the two sides of movable plate 3
Hole is connected with the flexible fixture block 8 in triangular prism-shaped, and flexible fixture block 8 by spring (not shown) in each mounting hole
Front side and 3 side of movable plate form inclined surface, and 8 rear side of fixture block that stretches forms vertical plane with 3 side of movable plate, in rectangular channel 6
Row's card slot 9 is provided on the cell wall of two sides, and the interval of adjacent card slot 9 is equal to the interval of adjacent expansion fixture block 8.
The flexible fixture block 8 of triangular prism-shaped has the function of being similar to box bolt, in movable plate 3 toward 5 side of buffer spring
When mobile, due to the effect on the 8 front side inclined-plane of fixture block that stretches, flexible fixture block 8 can be shunk in non-9 position of card slot, encounter 9 position of card slot
Automatic spring is inserted into card slot 9.Finally after effect of impact is complete, buffer spring 5 reaches corresponding compressive state, and stretch card at this time
Block 8 is inserted into the card slot 9 of corresponding position, and due to the effect of keeping out of 5 rear vertical surface of buffer spring, movable plate 3 will not be extensive
It is multiple to arrive original position, thus effectively prevent rebound effect.
Structure as one embodiment, crash bearer ontology 1 are made of the filling concrete inside rubber drum and rubber drum, outer layer
Rubber material, vehicle can be protected in minor impact, and the eolian erosion of cement in crash bearer can be reduced, filling concrete can increase
The weight for adding ontology avoids ontology too light and does not have any impact resistance effect；Reflection plaster 10 is equipped on crash bearer ontology 1,
It serves as warning.
Four corners of structure as one embodiment, pedestal 2 are equipped with inserted link 11, and the lower end diameter of inserted link 11
Greater than upper end diameter, during installation, inserted link 11 is embedded in road mixed mud, can increase the installation fastness of pedestal 2 in this way,
Bigger impact dynamics can be resisted.
Structure as one embodiment is stretched there are four fixture blocks 8, and interval is uniformly arranged.
The upper end of structure as one embodiment, the fixture block 8 that stretches is equipped with pulling piece 12, and pulling piece 12 is upper from movable plate 3
End is pierced by, and is being provided with space required for 12 synchronous movement of pulling piece through position, and specific structure is referring to Fig. 3.It is acted on
After each shock accident, manually shrink flexible fixture block 8 by pulling piece 12, so that movable plate 3 be made to be restored to original position.
The length of structure as one embodiment, buffer spring 5 is not less than 2m, can suitably be prolonged according to road speed limit situation
The length of long buffer spring 5, and spring requirement is thicker, general diameter is 1.5cm or more.
When specific installation is implemented again, structure used is all made of the biggish metal material of intensity in pre-buried mounting assembly, and
When road pavement, synchronous is embedded in mixed mud structure, keeps upper surface concordant with road surface, then by crash bearer ontology 1 and
Pre-buried mounting assembly is fixedly mounted.
Since the utility model can absorb the greater impact dynamics on a direction, so its field of employment is more specific,
What is promoted the use of in advance at present is the ramp exit position of super expressway, because the ramp exit section of super expressway is Frequent Accidents
Ground, many vehicles have little time to slow down, and directly knock shunting guardrail, and consequence is serious；Another reason is that at high speed ramp exit
Traffic accident is substantially along the shock of the direction of road, almost without lateral shock.When implementation, by the utility model
Pedestal 2 is mounted on shunting guardrail front-end along the direction of road, and when vehicle is hit, crash bearer ontology 1 can be with movement
Plate 3 moves on guide rod 4, forces buffer spring 5 to compress, buffer function is consequently formed.Certainly, it is hit in case of lateral
When hitting, as long as angle is not very big, and certain buffer function can be played；And since mounting structure is relatively firm,
Only if it were not for especially big lateral impact dynamics, product will not equally be damaged.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
