Description
Technical field
The utility model relates to a kind of vehicle driver place driving efficiency examination device, and particularly the field is examined with stake bar and field thereof and examined the limit for width door.
Background technology
According to Ministry of Public Security's " GA/T554-2008 vehicle driver place driving efficiency examination system " files specify, must examination motor vehicle accurate driver the correct judgement of vehicle body position " under certain speed of a motor vehicle to ", means of testing is " speed limit is by the limit for width door ", Fig. 3-1～Fig. 3-the 2nd, the synoptic diagram of limit for width door, require vehicle to pass through three limit for width doors of regulation successively during examination to be not less than the 20km/h speed of a motor vehicle, and must not the grazing hanging stick.Prior art and weak point thereof are: 1, hanging stick 22 usefulness external diameters are the iron pipe making of 20mm～40mm (range of size of standard code), and heavier, inertia is bigger, and the surface is also harder, when producing grazing with vehicle, easily vehicle are produced damage; 2, for to prevent that hanging stick 22 is subjected to the overlong time (standard code is for being not more than 20 seconds) of swinging after the grazing, majority is to bury magnet underground to apply damping strength under the subpoint of hanging stick to ground.After the ferropexy of burying earth magnetism, increase damping force, hanging stick (stake bar) will be closely liftoff, otherwise will be a little further; When magnet was too big to the suction of hanging stick (stake bar), hanging stick (stake bar) will produce bigger damage power to its vehicle of grazing.That is to say: examine the limit for width door with hanging stick (stake bar) the formation field that iron pipe is made, not only Installation and Debugging bother, and the damage that vehicle is produced is also big.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of field to examine integrated nothing injury stake bar and examine the limit for width door, the limit for width door is examined in the field of adopting this bar to make can significantly reduce a damaging action of pole pair examination vehicle.
The technical scheme that solves the problems of the technologies described above is: integrated nothing injury stake bar is examined in a kind of field, comprises rubber tube and is embedded in the interior volute spring of pipe.
Its further technical scheme is: form in the rubber tube of stake bar the middle part and be equipped with and be used to discern vehicle and pass through the sensor that the limit for width door is examined in the field, the sensor of identification vehicle grazing stake bar is installed at the subaerial end of stake bar.
Its another technical scheme is: the limit for width door is examined in a kind of field, comprise portal frame crossbeam and 2 hanging sticks, described hanging stick is made up of rubber tube and the volute spring that is embedded in the rubber tube, hang holder and be fixed on the crossbeam, the field is examined integrated nothing injury stake bar and is hung between the holder by connecting with spacing and coil spring assembly damping mechanism; The middle part is equipped with and is used to discern the sensor that vehicle passes through the limit for width door in the rubber tube of forming the stake bar, the sensor that is installed in two bars is aimed in opposite directions, all, the sensor of identification vehicle grazing stake bar is installed at the subaerial end of stake bar towards limit for width door inboard.
A kind of field of the utility model is examined integrated nothing injury stake bar and examined the limit for width door has following beneficial effect: 1, the damage of stake pole pair examination vehicle is little: field of the utility model examined integrated nothing injury stake bar and comprised rubber tube and be embedded in the interior volute spring of pipe, because its surface is not an iron and steel but elasticity rubber preferably, although so also can run into the situation of grazing examination vehicle, but the time of contact process is longer during with the examination vehicle collision, therefore, in following impulse force formula f=mv/t----(I) formula, f is an impulsive force, m is the quality of moving object, v is the movement velocity of object, t is 0 o'clock needs is reduced in moving object from speed v time, the product of mv is the momentum of moving object, from physical mechanics formula (I) as can be known, under the situation that momentum mv equates, because t action time is bigger, the impulsive force f that the vehicle of therefore taking an examination is subjected to just becomes less, can not produce the damage consequence to the examination vehicle under one situation.
2, installation, construction and easy to maintenance: 1. the field of the utility model is examined integrated nothing injury stake bar and is hung between the holder by connecting with spacing and coil spring assembly damping mechanism, rather than universal joint connects, therefore under the situation that guarantees flexible swinging, ratio of damping also keeps consistency easily, need not lose time when installing at the scene damping system is carried out careful adjustment process.
2. on the scene examining is equipped with the identification vehicle in the integrated nothing injury stake bar and passes through the sensor that the limit for width door is examined in the field, the sensor of identification vehicle grazing stake bar is installed at the subaerial end of stake bar, therefore, need be at other local similar devices of installing separately in place, this gives installation, construction and safeguards and all brought bigger convenience.
Below, in conjunction with the embodiments the technical characterictic of integrated nothing injury stake bar and field examining the limit for width door is examined in the field of the utility model and be further described.
