Abstract
The invention discloses a road headroom limiting device. The road headroom limiting device comprises support bars and a headroom-limiting cross bar, wherein the support bars and the headroom-limiting bar form an n-shaped structure; a height scanning and warning device is fixedly installed at one end of the headroom-limiting cross bar; a rolling shaft is installed below the headroom-limiting cross bar; a road blocking mesh is coiled on the rolling shaft; the height scanning and warning device is composed of a height scanner, a controller and an actuating mechanism; the height scanner, the controller and the actuating mechanism are connected in series through conducting wires; the actuating mechanism is fixedly connected with one end of the rolling shaft. According to the road headroom limiting device, driving safety for vehicles is guaranteed and safety of the headroom limiting device is guaranteed, so that problems are nipped in the mud; the road headroom limiting device not only is simple in structure, but also has the advantages of convenience, practicability and low cost.
Description
Technical field
The present invention relates to a kind of road traffic device, refer in particular to a kind of road height limiter.
Background technology
In some road section, due to reasons such as condition of road surface is not good, bridge load restrictions, height limiter is often set at corresponding passing road two ends, to limit the vehicle of certain altitude through this section; But because some driver vehicle, through this section, do not notice height-limiting frame, or not enough to vehicle Height Estimation, cause vehicle roof to scrape height limiter, cause vehicle or goods damaged, also can cause casualties time serious.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcome in background technology, provides a kind of road height limiter, this road height limiter, by scanning height of car at certain distance, putting down the net that is in the way in time reminds driver to stop in time, prevents vehicle from scraping height limiter, improves travel safety.
For solving the problem, the present invention takes following technical scheme:
A kind of road height limiter of the present invention, comprise pole, limit for height cross bar, described pole and limit for height cross bar form " door " character form structure, one end of described limit for height cross bar is installed with height scan alarming device, the below of described limit for height cross bar is provided with roller bearing, described roller bearing is wound with the net that is in the way, described height scan alarming device is made up of height scan instrument, controller and executing agency, described height scan instrument, controller are together with executing agency wired in series, and described executing agency is fixedly connected with one end of roller bearing.
A corrective measure of the present invention is, described in be in the way net adopt cotton rope braiding form.
Further improvement of the present invention measure is, described in be in the way net lower end weight is installed.
This section is arrived when vehicle travels, and during distance height limiter certain distance, height scan instrument detects vehicle, survey is swept to height of car simultaneously, and compare sweeping the limit for height safety value arranged in measured value and controller, the vehicle height value measured if sweep is less than limit for height safety value, then can not start executing agency; The vehicle height value measured if sweep is greater than limit for height safety value, then controller starts executing agency immediately, and executing agency drives spool fast rotational, puts down the net that is in the way, and to remind driver to brake in time, stops vehicle to continue to move ahead, prevents lance.The weight that the lower end of being in the way net the is installed net surface that can keep being in the way is smooth, is convenient to winding.
A kind of road height limiter of the present invention, owing to comprising pole, limit for height cross bar, described pole and limit for height cross bar form " door " character form structure, one end of described limit for height cross bar is installed with height scan alarming device, the below of described limit for height cross bar is provided with roller bearing, described roller bearing is wound with the net that is in the way, described height scan alarming device is by height scan instrument, controller and executing agency's composition, described height scan instrument, controller is together with executing agency wired in series, described executing agency is fixedly connected with one end of roller bearing, therefore this invention ensures that vehicle driving safety, also ensure that the safety of height limiter, accomplish to prevent trouble before it happens, the present invention not only structure is simple, and have conveniently, practical, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is principle framework figure of the present invention.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of road height limiter of the present invention, comprise pole 1, limit for height cross bar 2, described pole 1 and limit for height cross bar 2 form " door " character form structure, one end of described limit for height cross bar 2 is installed with height scan alarming device 3, the below of described limit for height cross bar 2 is provided with roller bearing 4, described roller bearing 4 is wound with the net 5 that is in the way, described height scan alarming device 3 is by height scan instrument 31, controller 32 and executing agency 33 form, described height scan instrument 31, controller 32 and executing agency 33 wire 6 are cascaded, described executing agency 33 is fixedly connected with one end of roller bearing 4.
The described net 5 that is in the way adopts cotton rope to weave and forms.
Described lower end of being in the way net 5 is provided with weight 7.
This section is arrived when vehicle travels, and during distance height limiter certain distance, height scan instrument 31 detects vehicle, survey is swept to height of car simultaneously, and compare sweeping the limit for height safety value arranged in measured value and controller 32, the vehicle height value measured if sweep is less than limit for height safety value, then can not start executing agency 33; The vehicle height value measured if sweep is greater than limit for height safety value, then controller 32 starts executing agency 33 immediately, and executing agency 33 drives spool 4 fast rotational, puts down the net 5 that is in the way, and to remind driver to brake in time, stops vehicle to continue to move ahead, prevents lance.The weight 7 that the lower end of being in the way net 5 is installed can keep net 5 surfacing that is in the way, and is convenient to winding.
Should be noted that; the foregoing is only the preferred embodiments of the present invention, be not limited to the present embodiment, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
