Abstract

The utility model discloses a buried collision prevention road barrier, which comprises a roller (vehicle blocking part), a bearing seat, a screw rod, a bevel gear, a transmission rod, a belt pulley, a motor, a travel switch, and a groove-shaped supporting frame. The utility model is characterized in that all the parts and components are fixed, supported, and assembled in a trench with appropriate depth at the exit-entrance passage way of vehicles through the groove-shaped supporting frame, the vehicle blocking part is the roller which can be lifted and rotated, and vehicles are blocked when the roller is lifted above the ground at a certain position; vehicles are allowed to pass through when the roller is declined in the trench. When the road barrier is in the blocking state, if vehicles rushes over, a corresponding reverse rotating motion (similar to wheel-slip) is generated after the roller and the driving wheels are contacted, thus the human casualty and the vehicle damage caused through the prior gate bar of the road barrier which is easy to be bumped bent, broke, or out of position can be avoided, simultaneously the forced passage of the vehicle can be effectively prevented, and the functions of security, crash prevention, and forced passage prevention of the utility model are completely achieved.

Description

Buried Anti-collision track gate

Technical field

The utility model relates to a kind of vehicle and imports and exports means of transportation, refers in particular to a kind of buried Anti-collision track gate that is used to control the vehicle turnover.

Background technology

At present on doorways such as each toll station, parking lot, enterprises and institutions and biotopes, the general banister that all is provided with prompting vehicle time-out, but existing these banisters all are to be connected on the control cabinet after being connected by restrictor bar or lock hurdle and rotating mechanism, and banister is let pass by the control vehicle that rises and falls on restrictor bar or lock hurdle.The subject matter that the banister of this structure exists is: because driver's error in judgement or vehicle braking performances are not good, cause vehicle to break through head a little sometimes, or because in a hurry, reason such as be open to the custom by force, the thing that knocked banister before banister rises happens occasionally.Consequently, gently then may smash windshield, damage vehicle, restrictor bar or lock hurdle hit curved, sever, knock away, heavy then also may cause personnel casualty accidents.Above-mentioned all situations make troubles for the vehicle management work and the driver at these road junctions, also exist bigger potential safety hazard.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of safe and simple in structure by the buried Anti-collision track gate of the rotatable roller bearing of liftable as the part of keeping off a car.Its technical scheme is: the utility model comprises roller bearing (part of keeping off a car), bearing support, screw rod, conical gear, drive link, belt pulley, motor, travel switch, troffer, and above-mentioned all component are by the troffer fixed support and be installed in the trench of vehicle access way mouth appropriate depth.

Its width of said trench and length are respectively by the diameter of roller bearing and length decision and satisfy and do not influence vehicle and pass through smoothly.

The two ends of the utility model roller bearing are connected with the upper end of screw rod by bearing support respectively, and the endoporus nut that the screw rod end portion screws in corresponding conical gear constitutes the twisting state with it; Constitute engagement between all conical gears and form link gear with drive link, belt pulley, motor.

By the technical solution of the utility model as can be seen, when motor obtains running instruction and drives drive link and make the conical gear rotation by belt pulley, screw rod moves up and down under the transfer function of corresponding conical gear endoporus nut, thereby drive the roller bearing lifting, realized vehicle is effectively stopped or lets pass.When roller bearing rises to the ground highest order, stop vehicle pass-through; Vehicle was let pass when roller bearing dropped in the trench.Because the troffer relevant position is provided with travel switch, makes roller bearing after finishing elevating movement, motor can cut off the power supply automatically, the roller bearing stop motion.As power failure, can on driven pulley, screw in dedicated handle by artificial return.

The jacking condition of this buried Anti-collision track gate is controlled by computer system instruction control or by the manual command by sensor.

The beneficial effects of the utility model are: when banister is in blocked state constitutes, if vehicle is broken through head, then roller bearing with drive wheel and contact after can generation corresponding reverse rotation campaign (being equivalent to wheel-slip), so can avoid the casualties that may cause and to the damage of vehicle, simultaneously effectively stop vehicle to pass through by force, reached safe, crashproof, the anti-function of passing through by force that the utility model had fully.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

Embodiment 1 is as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, and the utility model comprises roller bearing 11 (part of keeping off a car), bearing support 7,16, screw rod 8,17, conical gear 4,5,9,12,13, drive link 10,19, belt pulley 2,3, motor 1, travel switch 14,18, troffer 6,15.The two ends of roller bearing 11 are connected with the upper end of screw rod 8,17 by bearing support 7,16 respectively, and the endoporus nut that screw rod 8,17 end portions screw in corresponding conical gear 5,13 constitutes the twisting state with it; Constitute between all conical gears engagement and with drive link 10,19, belt pulley 3,2, motor 1 is formed link gear.When motor 1 obtains running instruction and drives drive links 19,10 and make the conical gear rotation by belt pulley 2,3, screw rod 8,17 moves up and down under the transfer function of corresponding conical gear 5,13 endoporus nuts, thereby drive roller bearing 11 liftings, realized vehicle is effectively stopped or lets pass.As power failure, can on driven pulley 3, screw in dedicated handle by artificial return.The jacking condition of this buried Anti-collision track gate is controlled by computer system instruction control or by the manual command by sensor.Said computer system instruction can be provided by the software section of banister; Said manual command can be provided by button or remote controller.

At last, by above technical scheme and technology general knowledge as can be known, the lifting of roller bearing also can realize by other kinds of drive such as air pressure, hydraulic pressure in the utility model.Therefore, above-mentioned disclosed embodiment just illustrates, and is not unique, and all are not breaking away from its spiritual essence or are being equal to any change of being done in the utility model scope all within rights protection scope of the present utility model.
