Summary of the invention
The purpose of this utility model is to provide a kind of road and bridge load limit protective device safe and reliable, that effectively avoid causing vehicle damage situation to occur.
For realizing the technical scheme that the purpose of this utility model adopts be: a kind of road and bridge load limit protective device; comprise the check weighing band being arranged on road and the mechanism of blocking the way; described check weighing band is provided with the anti-platform that falls into, and described anti-falling on platform is provided with the trigger switch being connected with the described mechanism of blocking the way.
Described check weighing band comprises groove and pressing plate, and described pressing plate and described groove are slidably connected, and described pressing plate is arranged with spring and the described anti-platform that falls into.
The described anti-platform that falls into is provided with elastic telescopic part, and described trigger switch is arranged on described elastic telescopic part top.
Described load limit protective device also comprises the gag lever post that is arranged on road both sides, on described gag lever post, is provided with probe, described probe with described in the mechanism of blocking the way be connected.
The described mechanism of blocking the way comprises block the way bar or retractable door.
Road and bridge of the present utility model, load limit protective device was by being arranged on the check weighing band on road and the mechanism of blocking the way; and in described check weighing band, be provided with the anti-platform that falls into; the situation of effectively having avoided overweight vehicle to be absorbed in groove occurs; avoid causing obstruction to traffic; effectively ensure vehicle and personnel's safety; by described anti-fall on platform, arrange with described in the trigger switch that mechanism is connected of blocking the way; in the time running into overweight vehicle; press down trigger switch by pressing plate; the control mechanism of blocking the way arranges roadblock; interception car is current, avoids overweight vehicle to cause damage to road and bridge.By being arranged on the gag lever post of road both sides, on described gag lever post, be provided with probe, described probe with described in the mechanism of blocking the way be connected, effectively avoid passing through of the super wide vehicle of superelevation, probe forms an electronics cross-arm on gag lever post, effectively avoid using traditional height-limiting bar to be clashed into by Overheight Vehicles or the generation of the situation of swiping, also avoided causing the generation of goods and damaged vehicle situation, once detect Overheight Vehicles, probe triggers the mechanism of blocking the way roadblock is set, and forbids that vehicle passes through.The utility model is simple in structure, safe, practical.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the anti-structural representation that falls into platform in the utility model.
Detailed description of the invention
Embodiment mono-
As shown in Figure 1: a kind of road and bridge load limit protective device, comprise the check weighing band 1 being arranged on road, block the way mechanism 2 and be arranged on the gag lever post 8 of described road both sides, described check weighing band 1 comprises groove 7 and pressing plate 5, described pressing plate 5 is slidably connected by slide rail with described groove 7, described pressing plate 5 is arranged with some springs 6, described groove 7 bottoms arrange the anti-platform 3 that falls into, described anti-falling on platform 3 is provided with the trigger switch 4 being connected with the described mechanism 2 of blocking the way, on described gag lever post 8, be provided with probe 9, described trigger switch 4 and described probe 9 respectively by control circuit with described in the block the way controller of mechanism 2 be connected, the described mechanism 2 of blocking the way is by the bar of blocking the way of described controller control.
Embodiment bis-
As shown in Figure 1 and Figure 2: the difference part of the present embodiment and embodiment mono-is: the described anti-platform that falls into is provided with elastic telescopic part, described trigger switch 4 is arranged on described elastic telescopic part top, described elastic telescopic part comprises that being arranged on described anti-2 of falling on platform 3 has the support 11 of through hole and be arranged on the expansion link 12 in described through hole, and described expansion link 12 is arranged on described support 11 by spring 13 and the locating part 14 being arranged on described expansion link 12.The described mechanism 2 of blocking the way is by the electric extendable door of controller control.
Road and bridge of the present utility model, load limit protective device was achieved in that when vehicle is during by gag lever post, vehicle carried out to super wide superelevation and detect, and can only could pass through gag lever post by not super wide vehicle, and driver easily judges whether width of roadway can pass through.For the vehicle of superelevation, once through gag lever post, will detector signal be formed and be blocked, probe will be sent to controller by superelevation signal, controls the mechanism of blocking the way roadblock is set, and implements interception, stops vehicle to pass through; By probe limit for height, can effectively avoid traditional cross-arm to cause the generation of vehicle or cargo damage situation; For super wide not higher vehicle again neither, the overweight situation causing because goods is heavier, can pass through gag lever post, in the time walking to check weighing band, because vehicle is overweight, pressing plate volume under pressure is larger, be triggered to trigger switch, trigger switch is by overweight signal is sent to control, and the controller control mechanism of blocking the way arranges roadblock, implement interception, stop vehicle to pass through.The anti-platform that falls into avoids overweight vehicle to cause pressing plate excessively to press down, and vehicle is absorbed in the generation of situation in groove, support vehicles and personnel's safety; And by anti-falling on platform, elastic telescopic mechanism being set, can effectively avoid trigger switch often to suffer weight, to ensure its application life and sensitivity.The utility model is simple in structure, safe, practical.
