Description
Technical field
The invention belongs to traffic safety facilities fields, and in particular to one kind can self-righting safe buffering height-limiting frame.
Background technique
Height-limiting frame is one of the important safety facility for protecting bridge, but while its interception Overheight Vehicles, there is also very big
Security risk, and after crashing, height-limiting frame damage can not restore, a large amount of manpower and material resources need to be spent to repair, gently then made
It at traffic jam, makes troubles to the normal trip of people, heavy then cause casualties and huge economic losses, the whole nation is respectively at present
The accident that ground Overheight Vehicles hit height-limiting frame frequently occurs, and is on the one hand driver's excessive velocities or judges incorrectly to headroom, not
Brake measure can be taken in time；It on the other hand is height-limiting frame unreasonable structure, nighttime visibility is poor, once accident occurs, to driving
The person of sailing and vehicle cause serious consequence.
At present to the improvement of height-limiting frame there are two types of thinking, one is pre-warning signal is arranged before height-limiting frame, by mark and
Signal lamp come remind driver pay attention to front height-limiting frame, another thinking is that height-limiting frame is made of flexible material, and reduction is touched
Loss caused by hitting.The present invention considers the visibility and resiliency of height-limiting frame simultaneously, and Overheight Vehicles driver is made actively to slow down
Meanwhile local collision energy is absorbed by buffer unit, the safety of height-limiting frame is improved, and height-limiting frame is automatically multiple after an impact
Original uses manpower and material resources sparingly.
Summary of the invention
In view of the problems of the existing technology, the technical solution that the present invention uses to solve problems of the prior art
It is as follows:
One kind can self-righting safe buffering height-limiting frame, the side of being fixed on the base is arranged in including symmetrically arranged pedestal
Column and the crossbeam that is arranged between column, it is characterised in that: pass through buffer unit between the crossbeam and column and connect, it is single
Heel post includes two that front and back is set side by side, and buffer unit is located at the top of column, and buffer unit includes being connected to before and after unilateral side
Double-layer guide rail between column, crossbeam left and right ends are connect with the buffer unit on two heel posts respectively, beam-end front and back
Connecting spring, beam-end upper and lower are arranged in double-layer guide rail, can slide along guide rail, and spring end, which is fixed with column, to be connected
It connects, when crossbeam is collided, by sliding of the crossbeam in double-layer guide rail, squeezes or extension spring, release a part are collided
Power.
It is connected and fixed between the column and pedestal by the fixing piece being embedded in road.
By oblique pull wirerope reinforcement by connection between the column and ground, height-limiting frame is further reinforced, height-limiting frame is prevented
It because collision is collapsed, is fixed between the two root posts of unilateral column front and back by several cross bars, increases Column stability.
With buffer unit linkage section be above the column it is detachable, be connected and fixed by split bolt, work as height-limiting frame
When upper layer crossbeam position is damaged, top maintenance replacement can be carried out, without dismounting total.
The crossbeam is composite and flexible material, while meeting rigidity requirement, has certain elasticity, filling inside crossbeam
High-performance closed pore energy-absorbing material can greatly reduce the impact force of Overheight Vehicles, the peace of effective protection driver and height-limiting frame facility
Entirely, while the damage of vehicle can also be reduced to limits.
It is coated with self-luminescent material on the column and crossbeam, absorbs luminous energy daytime, noctilucence improves the night of height-limiting frame
It is visual.
The stem height determines that beam width is depending on width of roadway by limit for height requirement.
The present invention has the advantage that
1, column and crossbeam are coated with self-luminescent material, and night automatic luminous improves the visuality at height-limiting frame night, remind
Overheight Vehicles driver is slowed down；
2, local collision energy, unfavorable shadow caused by reduction accident can be absorbed using the crossbeam of flexible material and buffer unit
It rings, improves the safety of height-limiting frame；
3, after collision vehicle is mobile, crossbeam automatically restores to original position, avoids temporary construction repairing, saves big
Measure manpower and material resources.

Fig. 2 is the overall structure schematic side view of this height-limiting frame；
Fig. 3 is flexible beam structure schematic diagram；
Fig. 4 is buffer unit structure schematic diagram；
Wherein: 1- fixing piece, 2- column, 3- crossbeam, 4- wirerope, 5- buffer unit, 6- double-layer guide rail, 7- spring.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described, such as Fig. 1-
Shown in 4, one kind can self-righting safe buffering height-limiting frame, including symmetrically arranged pedestal, the setting side of being fixed on the base
Column and the crossbeam being arranged between column, between crossbeam and column by buffer unit connect, unilateral column include front and back simultaneously
Two of column setting, buffer unit is located at the top of column, and buffer unit includes that the bilayer before and after being connected to unilateral side between column is led
Rail 6,3 left and right ends of crossbeam are connect with the buffer unit on two heel posts respectively, beam-end front and back connecting spring 7, crossbeam
End upper and lower be arranged in double-layer guide rail 6, can be slided along guide rail, 7 end of spring is fixedly connected with column, when crossbeam by
When collision, by sliding of the crossbeam in double-layer guide rail, extruding or extension spring discharge a part of impulsive contact force.
It is connected and fixed between column and pedestal by the fixing piece 1 being embedded in road.
By 4 reinforcement by connection of oblique pull wirerope between column and ground, height-limiting frame is further reinforced, prevents height-limiting frame because touching
It knocks down and collapses, fixed between the two root posts of unilateral column front and back by several cross bars, increase Column stability.
With buffer unit linkage section be above column it is detachable, be connected and fixed by split bolt, when height-limiting frame upper layer
When crossbeam position is damaged, top maintenance replacement can be carried out, without dismounting total.
Crossbeam 3 is composite and flexible material, while meeting rigidity requirement, has certain elasticity, filling is high inside crossbeam
Performance closed pore energy-absorbing material, can greatly reduce the impact force of Overheight Vehicles, the safety of effective protection driver and height-limiting frame facility,
The damage of vehicle can also be reduced to limits simultaneously.
It is coated with self-luminescent material on column and crossbeam, absorbs luminous energy daytime, noctilucence improves the visible at night of height-limiting frame
Property, while 50-100m left and right settings reminder flag and quick-fried lamp can be dodged in front of height-limiting frame.
Protection scope of the present invention is not limited to the above embodiments, it is clear that those skilled in the art can be to this hair
It is bright to carry out various changes and deformation without departing from scope and spirit of the present invention.If these changes and deformation belong to power of the present invention
In the range of benefit requirement and its equivalent technologies, then including the intent of the present invention also includes these changes and deforms.
