Description

Falling mound buffer-type height-limiting frame

Technical field

This utility model relates to a kind of falling mound buffer-type height-limiting frame, belongs to highway facilities field.

Background technology

At road, culvert, bridge and railway run through the running section of highway, in order to ensure vehicle driving safety, protection communal facility, prevent highly higher vehicle from being damaged by the facility on the road surfaces such as bridge, one height-limiting frame all can be set in relevant position, and indicate restricted driving height, two root posts are fixed in the both sides on common height-limiting frame Dou Shi road, it is connected on two columns by the height-limiting bar of a horizontally set, but this height-limiting frame has many inconveniences: height-limiting frame generally all can have limit for height to point out, but some is likely not to have the attention causing driver, or there is fluke mind in driver, but the whole height of vehicle is not sure (such as overloaded vehicle) by oneself, it is easy to hit on height-limiting frame, not only driver is easily injured, and height-limiting frame can be damaged.Height-limiting frame is generally all height-limiting bar bending when damaging, and column tilts, it is necessary to reinstalls height-limiting frame after being removed by height-limiting frame, adds maintenance cost.

Utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of falling mound buffer-type height-limiting frame, to provide buffering for height-limiting frame by the gravity of falling mound, prevent the direct collision of vehicle and height-limiting frame, decrease the damage of height-limiting frame and vehicle, it is ensured that driver's personal safety.

Falling mound buffer-type height-limiting frame described in the utility model, including the discrete column in road both sides, two column upper ends fix guide rail respectively, two guide rail parallels, arrange height-limiting bar in two guide rails, be respectively provided with a pulley and No. two pulleys outside guide rail, wherein pulley is in the front in height-limiting bar home position, cable wire one end is fixed on height-limiting bar, and the other end walks around a pulley respectively and No. two pulleys connect falling mound, and falling mound is placed in the deep-well below No. two pulleys.

Operation principle and process:

Under normal condition, height-limiting bar is pulled to slide rail (initial position) foremost by cable wire by the gravity of falling mound, when there being Vehicular impact height-limiting bar, height-limiting bar slides backward on slide rail, owing to height-limiting bar is connected with falling mound, the stroke of height-limiting bar is the stroke that falling mound raises, the gravity of falling mound provides pulling force to height-limiting bar and stops height-limiting bar to travel rearwardly, driver recognize bump against height-limiting bar after also can take brake measure, falling mound makes height-limiting bar have certain cushioning effect, avoid the damage that rigid impact causes, vehicle is withdrawn from rear height-limiting bar and is set back again under falling mound effect.

Height-limiting bar length is more than the distance between two columns, because when clashing into, vehicle is not generally just hit the center at height-limiting bar, height-limiting bar necessarily has one end coasting distance more relatively long in taxiing procedures, after the extreme position at arrival rear, height-limiting bar one end, the other end is likely to still in home position, and therefore, height-limiting bar should have enough strokes to provide buffering.

For preventing height-limiting bar and slide rail from sliding for a long time and wearing and tearing, arranging roller on height-limiting bar, height-limiting bar is contacted with slide rail by roller, effectively reduces the abrasion of height-limiting bar and slide rail, extends the service life of height-limiting frame.

Roller is the roller of free type, and roller can slide axially on height-limiting bar.

Adhering to foam rubber layer on the striking face of height-limiting bar, foam rubber layer is flexible, and not easily damages, and can reduce the damaged condition of vehicle and height-limiting bar when clashing into.

Limited block is fixed at height-limiting bar two ends, and the height of limited block is more than the gap of slide rail, it is prevented that height-limiting bar is extracted out from slide rail.

Slide rail is enclosed slide rail, it is prevented that clashes into and excessive causes that height-limiting bar departs from slide rail from top.

For ensureing that height-limiting bar has enough cushion strokes, the degree of depth of deep-well is greater than the length of slide rail.

This utility model is compared with prior art had the beneficial effect that

Falling mound buffer-type height-limiting frame described in the utility model, falling mound makes height-limiting bar have certain cushioning effect, avoid the damage that rigid impact causes, vehicle is withdrawn from rear height-limiting bar and is set back again under falling mound effect, greatly reduce accident rate, ensure personal safety and the communal facility safety of driver, reduced maintenance and maintenance cost, be suitable to promote the use of.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

As depicted in figs. 1 and 2, falling mound buffer-type height-limiting frame described in the utility model, including the discrete column 6 in road both sides, two column 6 upper ends fix guide rail respectively, two guide rail parallels, height-limiting bar 1 is set in two guide rails, a pulley 2 and No. two pulleys 3 it are respectively provided with outside guide rail, wherein pulley 2 is in the front in height-limiting bar 1 home position, cable wire 5 one end is fixed on height-limiting bar 1, the other end walks around a pulley 2 respectively and No. two pulleys 3 connect falling mound 7, and falling mound 7 is placed in the deep-well 8 below No. two pulleys 3.

Operation principle and process:

Under normal condition, height-limiting bar 1 is pulled to slide rail 4 (initial position) foremost by cable wire 5 by the gravity of falling mound 7, when there being Vehicular impact height-limiting bar 1, height-limiting bar 1 slides backward on slide rail 4, owing to height-limiting bar 1 is connected with falling mound 7, the stroke of height-limiting bar 1 is the stroke that falling mound 7 raises, the gravity of falling mound 7 provides pulling force to height-limiting bar 1 and stops height-limiting bar 1 to travel rearwardly, driver recognize bump against height-limiting bar 1 after also can take brake measure, falling mound 7 makes height-limiting bar 1 have certain cushioning effect, avoid the damage that rigid impact causes, vehicle is withdrawn from rear height-limiting bar 1 and is set back again under falling mound 7 acts on.

Height-limiting bar 1 length is more than the distance between two columns 6, because when clashing into, vehicle is not generally just hit the center at height-limiting bar 1, height-limiting bar 1 necessarily has one end coasting distance more relatively long in taxiing procedures, after the extreme position at arrival rear, height-limiting bar 1 one end, the other end is likely to still in home position, and therefore, height-limiting bar 1 should have enough strokes to provide buffering.

For preventing height-limiting bar 1 and slide rail 4 from sliding for a long time and wearing and tearing, arranging roller on height-limiting bar 1, height-limiting bar 1 is contacted with slide rail 4 by roller, effectively reduces the abrasion of height-limiting bar 1 and slide rail 4, extends the service life of height-limiting frame.

Roller is the roller of free type, and roller can slide axially on height-limiting bar 1.

Adhering to foam rubber layer on the striking face of height-limiting bar 1, foam rubber layer is flexible, and not easily damages, and can reduce the damaged condition of vehicle and height-limiting bar 1 when clashing into.

Limited block 9 is fixed at height-limiting bar 1 two ends, and the height of limited block 9 is more than the gap of slide rail 4, it is prevented that height-limiting bar 1 is extracted out from slide rail 4.

Slide rail 4 is enclosed slide rail 4, it is prevented that clash into excessive cause height-limiting bar 1 from top depart from slide rail 4.

For ensureing that height-limiting bar 1 has enough cushion strokes, the degree of depth of deep-well 8 is greater than the length of slide rail 4.
