Description
Technical field
The utility model relates to highway bridge field, specifically a kind of road and bridge height limiter.
Background technology
Height-limiting bar can ensure traffic safety better; play the effect preventing vehicle super-high, protection road and bridge facility well, many highways have setting, but often occurs the situation that height-limiting bar breaks by vehicle; cause vehicle and height-limiting bar to damage, also affect traffic.Tracing it to its cause is traditional height-limiting bar function singleness, cannot detect in advance and warn, and causes driver observe thinless or be out of one's reckoning to height of car, accident often can be caused to occur.
Utility model content
The purpose of this utility model is to provide a kind of road and bridge height limiter, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of road and bridge height limiter, comprise bridge height-limiting gantry, light caution board, bridge limit for height interception bar, deceleration strip and photoelectric sensor, described bridge height-limiting gantry top is provided with hydraulic jack, bridge limit for height interception bar is connected by elevating lever bottom hydraulic jack, bridge limit for height interception bar two ends are embedded in the guide chute inside bridge height-limiting gantry, described bridge limit for height interception bar is provided with displacement transducer, displacement transducer is connected with control system, described bridge height-limiting gantry front end is provided with the deceleration strip of 30-60 rice, deceleration strip end is provided with limit for height column, limit for height column is provided with the photoelectric sensor of a band reflecting plate, photoelectric sensor control connection light caution board.
As further program of the utility model: described bridge height-limiting gantry adopts shaped steel welding manufacture to form.
As further program of the utility model: described bridge limit for height interception bar external sheath has flexible material.
As further program of the utility model: described light caution board is arranged on bridge height-limiting gantry.
Compared with prior art, the beneficial effects of the utility model are: described a kind of road and bridge height limiter, structure is simple, easy to use, by regulating the headroom of the displacement restriction vehicle of bridge limit for height interception bar, detecting the height of vehicle by photoelectric sensor and by light caution board, driver being reminded, significantly to reduce the accident generation that Overheight Vehicles knock bridge limit for height interception bar, safe and reliable, economical and practical, effectively can stop Overheight Vehicles and pass through.
Accompanying drawing explanation
