Description

A kind of anti-terrorism roadblock

Technical field

The utility model relates to a kind of road roadblock preventing vehicle from illegally passing through.

Background technology

Frontier defense is the important barrier of territorial integrity and safety of safeguarding one's country, its defendance border area safety and maintain country continual and steady in played the inadvisable effect replaced, therefore safeguard that the trouble free service of frontier defense is particularly important.More early stage Frontier Defence Inspection Stations adopt the Simple road-block equipment such as traditional electric lifting rod or retractable door, and it is very large that terrorist rushes the risk closing attack; The roadblock equipment that other place of military importance, oil depot, ammunition depot etc. adopt is also simpler and easy, adopt heavy anti-collision unit, 2-4 people is needed to lift, labour intensity is quite large, and all automobiles can not be tackled completely, rush card phenomenon to happen occasionally, highly dangerous is brought to the life security of soldier and the protection of place of military importance.The a lot of roadblock adopting barbed device of tyre of existing anti-probably roadblock design, when terrorist intention drive illegal punching pass ground roadblock time, thorn device of tyre is carved and is punctured doughnut, by exitting and then forcing car deceleration until stop, but this roadblock cannot be forced at once and be stopped automobile, the tire that especially some performances are good, is punctured and also can not exits at once, automobile still can keep traveling to complete punching pass more at a distance, causes frontier guard or guard soldier's injures and deaths and place of military importance to be invaded.Along with improving constantly frontier defense safety requirements, be necessary to develop a kind of use more reliable, protect more efficiently anti-terrorism roadblock.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of anti-terrorism roadblock.

The utility model solves the technical scheme that its technical problem adopts:

A kind of anti-terrorism roadblock, comprise the support frame being embedded in underground, described support frame top is provided with the cover plate concordant with road surface, it is characterized in that: described cover plate hollow, be reserved with the passage I for the first elevating mechanism lifting, described first elevating mechanism is included in drive system I and acts on the lower lift supporting rod that can move up and down, be fixedly connected on the elevator chamber on lift supporting rod, and being positioned at the broken tire tooth of horizontally set on elevator chamber top, the cross sectional shape of described passage I mates with the cross sectional shape of described broken tire tooth; The second elevating mechanism is provided with in described elevator chamber, described second elevating mechanism is included in drive system II and acts on the lower lifting shaft that can move up and down, and the obstacle net be fixedly connected on lifting shaft, elevator chamber surface is reserved with the passage II for the lifting of obstacle net, and the cross sectional shape of described passage II and the cross sectional shape of described obstacle net match.

Described lift supporting rod is two, lays respectively at the two ends in support frame; Described elevator chamber both sides outer wall is provided with limited block and is fixedly connected on lift supporting rod.

Described obstacle net comprises the base plate be fixedly connected with lifting shaft, base plate is fixed with and organizes independently obstacle bar unit more, often organizes obstacle bar unit and to be connected by a cross bar by montant between two and to form.

Described drive system I, II is Pneumatic drive system or fluid power system.

The beneficial effects of the utility model are: the utility model changes easy protection form in prior art, double shield is defined by the setting of first, second elevating mechanism, the protective capacities of the key sector such as effective raising place of military importance, oil depot, ammunition depot, Frontier Defence Inspection Station, the security protection of the department that attaches most importance to and the life security of guard soldier provide effective guarantee.

Detailed description of the invention

Referring to figs. 1 through Fig. 5, a kind of anti-terrorism roadblock, comprise the support frame 1 being embedded in underground, described support frame 1 top is provided with the cover plate 2 concordant with road surface, described cover plate 2 hollow, be reserved with the passage I 21 be elevated for the first elevating mechanism 3, described first elevating mechanism 3 is included in drive system I 5 and acts on the lower lift supporting rod 31 that can move up and down, be fixedly connected on the elevator chamber 32 on lift supporting rod 31, and being positioned at the broken tire tooth 33 of horizontally set on elevator chamber 32 top, the cross sectional shape of described passage I 21 and the cross sectional shape of described broken tire tooth 33 match; The second elevating mechanism 4 is provided with in described elevator chamber 32, described second elevating mechanism is included in drive system II 6 and acts on the lower lifting shaft 41 that can move up and down, and the obstacle net 42 be fixedly connected on lifting shaft 41, elevator chamber 32 surface is reserved with the passage II 34 be elevated for obstacle net 42, and the cross sectional shape of described passage II 34 and the cross sectional shape of described obstacle net 42 match.

As preferably, described drive system 6 adopts Pneumatic drive system or fluid power system, and response speed is faster, and accuracy is higher.

During utility model works, lift supporting rod 31 drive system I 5 act under earthward direction do ascending motion, the elevator chamber 32 be then fixed on lift supporting rod 31 moves upward thereupon, because elevator chamber 32 top is provided with horizontal broken tire tooth 33, then behind its emersion ground, as long as there is vehicle to pass through just can puncture tire, this is the first line of defence; Simultaneously, as second elevating mechanism 4 in second defence line, it is built in elevator chamber 32, elevator chamber 32 surface is reserved with passage II 34, when lifting shaft 41 moves upward under drive system II 6 acts on, the obstacle net 42 be fixedly connected on lifting shaft 41 rises in direction earthward through passage II 34, is stopped by automobile impassable completely, thus achieves double shield.And after soldier completes normal verification formality, first, second elevating mechanism return can be operated, now, obstacle net 42 is hidden in elevator chamber 32, and the broken tire tooth 33 on elevator chamber 32 and top thereof is hidden in support frame 1, after whole mechanism is built-in, broken tire tooth 33 surface is concordant with cover plate 2 surface, do not affect vehicle to travel, vehicle can normally be let pass.

As preferred embodiment of the present utility model, described lift supporting rod 31 is two, lays respectively at the two ends in support frame 1, and the operation of elevator chamber 32 is more steadily reliable; Elevator chamber 32 both sides outer wall is provided with limited block 35 and is fixedly connected on lift supporting rod 31, elevator chamber 32 be down to brokenly tire tooth 33 retract support frame 1 and concordant with support frame cover plate 2 time stop.

With reference to Fig. 6, the obstacle net 42 of the present embodiment comprises the base plate 43 be fixedly connected with lifting shaft 41, base plate is fixed with and organizes independently obstacle bar unit more, often organize obstacle bar unit to be connected by a cross bar 45 by montant 44 between two and to form, make the passage II 34 on elevator chamber 32 surface and the completely through passage of non-transverse, both can provide passage, again can guaranteed strength, reasonable in design, safe and reliable.

The utility model changes easy protection form in prior art, double shield is defined by the setting of first, second elevating mechanism, the protective capacities of the key sector such as effective raising place of military importance, oil depot, ammunition depot, Frontier Defence Inspection Station, the security protection of the department that attaches most importance to and the life security of guard soldier provide effective guarantee.
