Embodiment ten, on the basis of embodiment nine, 4 upper end of third fixed link is fixed with solar panels 68, described
68 lower end of solar panels has the street lamp 69 being arranged in third fixed link 4, the solar panels 68 that can be used as driving motor 14
External power supply because the reason of many Vehicular impact height-limiting bars is night insufficient light so that driver's mistake is underestimated
The height of height-limiting bar, therefore, we are arranged street lamp 69 and are illuminated for device, and installation solar panels 68 can be as driving motor 14
The power supply of external power supply and street lamp 69, is more energy-saving and environmentally friendly.
In the use of the present invention, drive first gear axis 12 to rotate by controlling driving motor 14 first, first gear axis
12 can drive second gear 11 to rotate, and the first gear 10 engaged with 11 gear of second gear is then driven to rotate, final to drive
Rotation lifting is completed with the rotation lifting column 15 of 10 screw-thread fit of first gear, when the rotation of 10 screw-thread fit of first gear lifts
When the rotation lifting of column 15, being sequentially connected by belt 20, which can drive another rotation lifting column 15 to complete synchronous rotation, lifts,
It is connected through elevating lever upper end link slot 24 between elevating lever 23 and rotation lifting column 15, elevating lever 23 and the first fixed link 5 are slided
Connection, such connection type to rotate elevating lever 23 when lifting column 15 rotates and does not follow rotation, and rotates the rising of lifting column 15
When elevating lever 23 can be driven to rise, connected through connecting plate 22 between two elevating levers 23 so that connecting plate 22 can follow elevating lever
23 complete simultaneously lift, realize adjusting height purpose, when the emergency vehicles such as fire-fighting vehicle and ambulance need by when,
Height can be adjusted to let pass, in addition, needing to adjust height-limiting bar height to adapt to the vehicle flowrate of different periods or adjusting height
When degree limitation headroom, so that it may to adjust elevating lever height；In the case where connecting rod 44-1 drives, connecting pole 44 can be with elevating lever 23
Synchronization lifting, it is ensured that when the limit for height of two groups of height limiters is the same；Two 44 insides of connecting pole are through the second shaft
It is rotatably connected to the second rotor plate 45, when being passed through by limit for height vehicle compulsory, vehicle hits the second rotor plate 45 first, and second
Rotor plate 45 is rotated around connecting pole 44 towards both sides, and the telescopic rod 46 being then fixedly connected with rotor plate 45 can drive the first card column
47 rotate synchronously, and card column turn trough 51 are detached from 47 rotation process of the first card column, at this point, flap 48 is by compressed compression bullet
The effect that spring 50 discharges compressing force can bounce, and deceleration block 49 can be raised up to 1 surface of roadbed, and deceleration block 49 slows down to vehicle,
When needing to restore, it is only necessary to deceleration block 49 is pressed under roadbed 1, then restore rotor plate 45 so that the first card column 47 is blocked again
Inside card column turn trough 51, progress is synchronized, the first bevel gear 52 that telescopic rod 46 drives lower end to be arranged rotates, and first
Bevel gear 52 drives the second bevel gear 53 of engagement to rotate, and second bevel gear 53 drives 55 turns of the first line wheel connected through shaft
It is dynamic, the meeting lay winding wire ropes 56-1 during the first line wheel 55 rotates, then so that steel wire rope 56-1 pulls the second card column 57
It is detached from the groove that 58 left and right sides of plate of sinking is arranged, the plate 58 that sink at this time can sink, when the trailing wheel of vehicle is by sagging pit
When can slow down to vehicle, it is synchronous accident prompt driver is occurred to driver's prompt to take braking, when needs are extensive
When multiple, setting draw ring 59 is so that the recovery for the plate 58 that sink is more convenient；Synchronous with above-mentioned steps to carry out, telescopic rod 46 drives
The first bevel gear 52 that lower end is arranged rotates, and first bevel gear 52 drives the third hand tap gear 54 of engagement to rotate, third hand tap gear
It is rotated synchronously by the third gear 60 that shaft connects in 54, third gear 60 drives 61 turns of the 4th gear engaged with its gear
Dynamic, the 4th rise of the gear 61 with carry-over bar 66, rack 66 drives the upper lift slab being fixedly connected with rack 66 during rising
67 rise after upper lift slab 67 rises, when vehicle is into out-of-date, can generate vehicle slowing effect, and it is pre- so that driver obtains
It is alert, it is fixed with pawl fixed block 63 in the shaft of the 4th gear 61, the pawl fixed block 63 is provided with pawl 64, and the described 4th
Gear 61 is internally provided with pawl pockets 62 identical with 64 front end geometry of pawl, and the presence of pawl 64 makes the 4th gear 61 not
It can invert, so that upper lift slab 67 is not fallen out after rising, when needing to restore, it is only necessary to by pawl fixed block 63 along keyway 65
Sliding so that the 4th gear 61 may be implemented to invert, and upper lift slab 67 is easily achieved reset at this time；When vehicle continues on shock
When anti pressure devices 34, first shock block 35 can be hit first, first shock block 35 compresses the first spring 37, then in second shock
36 internal slide of block, impact bar 39 can then pull extension spring 41, three different bullets in impact 31 internal slide of rod through-hole
The smaller spring of spring constant of the first spring coupling plate 40 is connected in the spring of spring coefficient stress to be deformed upon first, finally
The larger spring for being fixed to connecting rod 33 of spring constant finally deforms upon, and has delayed extension spring 41 to a certain extent in this way
Pull connecting rod 33 so that driver has certain brake reaction time, when extension spring 41 continues to be pressurized, can drive connection
Bar 33 is moved to 39 direction of impact bar, and the connecting rod 33 of both sides can synchronize intermediate movement, then be disconnected mouth 25, rotate at this time
Plate 28 can freely around rotation slot 26 rotate, violation vehicle is temporarily let off, staff does post-processing, ensured vehicle,
Height-limiting bar not damage by being damaged property, has also ensured driver in the process and will not come to harm or even life danger, when needing
When restoring, it is only necessary to press first shock block 35 so that connecting rod 33 is moved to 39 direction of impact bar, at this time by 39 liang of impact bar
Stop pressing after end alignment connector 25, then impact bar 39 comes back to inside connector 25, and device restores reset condition.
