Description
Technical field
Municipal technical field is the utility model is related to, specifically a kind of town road height-limiting bar.
Background technology
Municipal height-limiting bar is limitation major measure of the lorry by important highway division, is had every year because oversize vehicle is unrestricted
The strategic road made and be subject to crushing, and then spend substantial amounts of price to go to safeguard highway again, and high capacity waggon easily causes traffic jam,
Traffic accident easily occurs simultaneously.
Existing town road height-limiting bar Height Standard has a variety of, but this height-limiting bar does not all have regulatory function, once
During more than height-limiting bar, all vehicles all can not be by, and when oversize vehicle does not pay attention to height-limiting bar or thinks that height-limiting bar can lead to
Cross, during along with passing through under road conditions of no illuminating lamp at night, it is easy to knock height-limiting bar, and oversize vehicle quickly through when,
Height-limiting bar is easy to block broken on vehicle, or even threatens the life security of people, is seated because for long-distance bus, car is superior
Many passengers, caused casualties if as height-limiting bar, this is not that we want to see, nor height-limiting bar is original
It is intended to.
Therefore, in the case, the utility model provides a kind of new device to solve this problem.
Utility model content
For the above situation, to overcome the defect of prior art, the utility model provides a kind of town road height-limiting bar, had
Effect solves the problems, such as that existing town road height-limiting bar can not be adjusted.
The utility model includes two vertical columns, and column top is fixed with the crossbeam of limit for height specification, it is characterised in that
The upper part of two columns is equipped with rack, and gear is engaged with rack, is fixed between two gears and is placed in below the crossbeam
Metal rotating shaft, the both ends of metal rotating shaft are arranged with reel, the electromagnet being set in metal rotating shaft, volume are provided with reel respectively
Through expansion link connecting cross beam, metal rotating shaft lower end is connected with flap, and limit for height mark and speed are fixed with crossbeam for cylinder upper end
Tester, electromagnet and speed tester are connected with electric supply installation, and speed tester controls the energization of electromagnet by signal.
Preferably, bearing is provided with below described column, bearing is through being bolted to ground.
The utility model is simple in construction, can both play a part of limit for height, moreover it is possible to when allowing the vehicle of superelevation to be not intended to pass through not
Have a casualties, and Overheight Vehicles by when vehicle have damage, avoid Overheight Vehicles are immoderate from crude an dimpetuous passing through.
Brief description of the drawings
Fig. 1 is the utility model front view schematic diagram.
Embodiment
About of the present utility model foregoing and other technology contents, feature and effect, in following cooperation refer to the attached drawing 1 to reality
In the detailed description for applying example, can clearly it present.The structure content being previously mentioned in following examples, it is with Figure of description
For reference.
Each exemplary embodiment of the present utility model is described below with reference to accompanying drawings.
Embodiment, the utility model are town road height-limiting bar, including two vertical columns 1, and the top of column 1 is fixed
The crossbeam 2 of limited high standard, one section of rack 3 is equipped with the upper end of two columns 1, fixed gear 4 is engaged with rack 3,
The metal rotating shaft 5 being placed in below crossbeam 2 is fixed among two gears 4, the both ends of metal rotating shaft 5 are arranged with reel 6 respectively,
Electromagnet 7 is provided with reel 6, electromagnet 7 is rounded, is equally set in metal rotating shaft 5, when 7 no power of electromagnet, metal
Rotating shaft 5 can realize and freely rotate that reel 6 is fixedly arranged above expansion link 8 on electromagnet 7, and the other end of expansion link 8 is fixed on
On crossbeam 2, flap 9 is connected with the lower end of metal rotating shaft 5, flap 9 can drive metal rotating shaft 5 to rotate, also solid on crossbeam 2
Fixed limited high mark 10 and speed tester 11, could be arranged to radar velocity measurement, electromagnet 7 and speed tester 11 are connected with confession
Electric installation, speed tester 11 control the energization of electromagnet 7 by signal, and the lower section of column 1 is additionally provided with bearing 12, and bearing 12 passes through
Bolt 13 fixes on the ground.
When have vehicle by when, if vehicle is not above limit for height standard, then vehicle can be directly by when vehicle surpasses
When crossing limit for height standard, now speed tester 11 detects car speed, and when car speed reaches a certain value, the value can be according to reality
Border situation setting, for example, when setting value is 0-30 codes, speed tester 11 is signaled to electromagnet 7, and now electromagnet 7 is logical
Electricity, and when no car by when, electromagnet 7 is also powered, the adsorbing metal rotating shaft 5 of electromagnet 7 so that metal rotating shaft 5 can not rotate,
Car speed more slowly by when, metal rotating shaft 5 does not rotate, and flap 9 does not also rotate, and vehicle can not be by, when speed is very fast, speed
When detecting speed more than 30 yards, electromagnet 7 powers off degree tester 11, and now rotating shaft can rotate in reel 6, when vehicle with
Fast speed by when, vehicle touching flap 9, flap 9 drive metal rotating shaft 5 rotate, metal rotating shaft 5 drive both sides gear 4
Rotate, gear 4 moves up a segment distance on rack 3, and now reel 6 moves upwards also with expansion link 8, so as to which vehicle can
With by the way that but vehicle is remained and touches flap 9, and car has been injured, and our purpose is to ensure the peace of personnel
Entirely, will not allow height-limiting bar scratch automobile and then makes casualties.
The utility model is simple in construction, can both play a part of limit for height, moreover it is possible to when allowing the vehicle of superelevation to be not intended to pass through not
Have a casualties, and Overheight Vehicles by when vehicle have damage, avoid Overheight Vehicles are immoderate from crude an dimpetuous passing through.
