The specific embodiment
In order to improve the protection effect of protective guard, the utility model embodiment provides a kind of protective guard, in the technical solution of the utility model, by obstruction block being fixed on the column of protective guard, thereby make column in the time being fallen by band, protective fence beam can keep certain height, stops vehicle to go out track, thereby has improved the protection effect of protective guard.For making the purpose of this utility model, technical scheme and advantage clearer, below as an example of nonrestrictive embodiment example, the utility model is described in further detail.
As shown in Figure 2, the utility model embodiment provides a kind of protective guard, and this protective guard comprises at least one crossbeam 40 and many root posts 10, and is slidably connected by obstruction block 30 between every crossbeam 40 and every root post 10.
The radical of crossbeam 40 wherein can be different radical, as: one, two, three etc., and crossbeam 40 is by vertically upward sliding of obstruction block 30, below to adopt a crossbeam to describe as example.
As shown in Figure 4, Fig. 4 shows protective guard that the present embodiment provides by the stressed reference diagram after hitting, in the time that vehicle knocks down on protective guard, impulsive contact force makes column 10 run-off the straights, the power that now vehicle is applied on crossbeam 10 has a component upwards, and under the effect of this component, crossbeam 40 drives obstruction block 30 upward sliding on column 10, thereby crossbeam 40 can not tilted with column 10 and reduce, keep its vertical height apart from track.Guarantee that by the upward sliding of crossbeam 40 crossbeam 40 still can keep stopping the height of vehicle, has improved the protection effect of protective guard after column 10 tilts.
Slidable fit between obstruction block 30 and column 10 wherein can realize by different structures, as: on column 10 or obstruction block 30, on one of them, chute is set, the projection that relative set coordinates with chute on another, can realize the relative sliding between obstruction block 30 and column 10.Preferably, the structure of slidable fit adopts structure as shown in Figure 3, and Fig. 3 shows the structure of obstruction block 30, is provided with inverted U-shaped chute 32 on obstruction block 30, now, is equipped with the first bolt 20 being slidably matched with inverted U-shaped chute 32 on column 10.In the time adopting this kind of structure, without the structure of change column 10, only need on obstruction block 30, set up an inverted U-shaped chute 32, be convenient to produce.In the time that protective guard is installed, the first bolt 20 is located on column 10, and the one end of stretching out at screw rod connects top nut, in the time that obstruction block 30 is installed, inverted U-shaped chute 32 is enclosed within on the screw rod of the first bolt 20, and the screw head of the first bolt 20 is stuck in the another side of chute, thereby prevents that obstruction block 30 from dropping, and can, by the nut on rotation the first bolt 20, adjust the tightness between obstruction block 30 and column 10.Obstruction block 30 when mounted, under the effect of gravity, the cell wall at the top of inverted U-shaped chute 32 compresses and contacts with screw rod, the weight of carrying obstruction block 30, now, obstruction block 30 is positioned at least significant end, in the time that crossbeam 40 is subject to vehicle collision, the vertical component that impulsive contact force produces makes obstruction block 30 upward slidings, simultaneously, because crossbeam 40 is slidably connected from different columns 10 by different obstruction block 30, in the time that vehicle collides the crossbeam 40 between two columns 10 of two neighbours, obstruction block 30 on other columns 10 also there will be upward sliding under the drive of crossbeam 40, thereby avoid single crossbeam 40 to rise and caused the rigid breakage connecting between crossbeam 40.
When obstruction block 30 is connected with crossbeam 40, be fixedly connected with by the second bolt, now, on obstruction block 30, be provided with the connecting hole 33 coordinating with the second bolt, and the top height of this connecting hole 33 be not less than the top height of inverted U-shaped chute 32.Concrete, the difference in height between the top height of connecting hole 33 and inverted U-shaped chute 32 top height is not more than 6cm.While maintenance in track, need asphalt, its laying depth is not more than 6cm, and the obstruction block 30 that the present embodiment provides is because connecting hole 33 positions arrange higher, thereby guaranteed after track maintenance, crossbeam 40 still can keep enough height to stop that vehicle goes out track.
In order further to improve crossbeam 40 after being impacted, obstruction block 30 can upward sliding, preferred, obstruction block 30 be connected with crossbeam 40 face be downward-sloping inclined-plane, and angle between inclined-plane and perpendicular is not more than 8 °.This angle can be 1 °, 2 °, 3 °, 4 °, 5 °, 6 °, 7 °, 8 ° etc. and be not more than arbitrarily the angle of 8 °, preferably, the angle of inclined-plane and vertical plane is 6 °, has improved the vertical component of obstruction block 30, be convenient to obstruction block 30 and slide, be conducive to reduce the lateral displacement of crossbeam 40.Continue with reference to figure 3, in the time that this joint face adopts inclined-plane, in the time that crossbeam 40 is fixed on obstruction block 30, because the face connecting is inclined-plane, thereby cause the crossbeam 40 of installing also to possess certain downward-sloping angle, in the time that vehicle collides on crossbeam 40, can be known by simple stress analysis, the crossbeam 40 being obliquely installed makes crossbeam 40 in the time being subject to colliding, and has enough power to drive obstruction block 30 upward slidings, guarantee that crossbeam 40 is after being collided, still can stop that vehicle goes out track.
Crossbeam 40 wherein can adopt the crossbeam 40 of different structure, and as square steel, corrugated fence rail etc., preferably, crossbeam 40 is corrugated fence rail.Now, the top of obstruction block 30 has projection 34, and this projection 34 extends in the trough of corrugated fence rail.Continue with reference to figure 4, in the time that vehicle knocks down on crossbeam 40, there is deformation in crossbeam 40, conflicts with projection 34, now, impulsive contact force is delivered on obstruction block 30 with the resistance surface of projection 34 by the second bolt and crossbeam 40, has improved the stressing conditions of obstruction block 30, makes obstruction block 30 stressed more even, simultaneously, in the time that obstruction block 30 slides, projection 34 also provides a vertical component with the contact surface of crossbeam 40, is convenient to obstruction block 30 upward slidings.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
