The utility model is characterized in that an overloading sensing oil cylinder unit (6) is arranged in a rectangular array shape relative to ground; the sensing oil cylinders are communicated with each other through an oil pipe and the jacking oil cylinder of the car arrester (3) by an oil pressure pipe return circuit (5). The overloading sensing oil cylinder unit (6) is arranged with the stop (7) of the overloading sensing oil cylinder pressure lever (8) inside; the upper part of the overloading sensing oil cylinder pressure lever (8) in the overloading sensing oil cylinder unit (6) is installed with an overloading sensing clamp plates (9); each overloading sensing clamp plate (9) is arranged in grid type mutually independently. The utility model uses pressure intensity to control whether the big or small vehicle is overloaded or not; one group of the utility model is installed on the foundation at the left and the right side of the main road or bridge respectively with a regressing stopper without using persons or electricity. The utility model can be used in the monitoring of vehicles in any sizes. The utility model has a short-time online monitoring and can figure out whether the vehicle is overloaded or not quickly so as to increase the smooth moving of the unloaded vehicles and solve the traffic block problem caused by monitoring the overloading vehicles on the road.
Description
Technical field:
The utility model belongs to the current device of road vehicle overload restriction, is specifically related to a kind of full-automatic road, bridge load limit device.
Background technology:
In the known technology, the online overload supervision of the road meausring apparatuses that adopt determine by display unit whether vehicle overloads more again.No matter be to take the electronic sensor value, or split axle weighs, no matter whether vehicle overload, and all wants bicycle to weigh, consuming time very long.Cause regular traffic congestion, have a strong impact on smooth traffic.The technical scheme of Chinese patent ZL02276965.X disclosed a kind of " ultra-thin dynamic, static dual use highway overload protection device ", and the technical scheme of ZL94114844.0 a kind of " weighing automotive axles separately device ", all need complicated weighing display unit, the quick overload that is unfavorable for vehicle is confirmed, and is consumed people, power consumption.
Summary of the invention:
The purpose of this utility model provides a kind of on-line monitoring, is convenient to the classification supervision, and weak point consuming time is fast confirmed the full-automatic road of fluid pressure type, bridge load limit device that whether vehicle overloads, solves the blockage problem that highway causes because of the monitoring overloaded vehicle.
The utility model is taked following technical scheme.
The full-automatic road of a kind of fluid pressure type, bridge load limit device, include car arrester, overload induction oil cylinder group is matrix with respect to ground and arranges, each responds to oil cylinder with the interconnected UNICOM of oil pipe, and with the jacking cylinder of oil pressure pipe loop UNICOM car arrester, the stop of overload induction oil cylinder depression bar is set in the overload induction oil cylinder group, and the overload induction oil cylinder depression bar upper end in the overload induction oil cylinder group is provided with overload induction pressing plate, and each overload induction pressing plate is formed separate grid type and arranged.The top surface area of unit overload induction pressing plate is between 40～60 square centimeters.Surface area is more little, and monitoring accuracy is high more.
Side at device also is provided with retrograde car blocking device, and car blocking device oil cylinder upper end connects the jacking of hydraulic pressure pole and blocks the bar oscilaltion, and the car blocking device oil cylinder connects oil pipe and overload induction oil cylinder group oil pressure pipe loop UNICOM in parallel.
Operating principle of the present utility model is such, and the full-automatic road of fluid pressure type, bridge load limit device can be one meter wide (satisfy tyre width get final product), and length can generally can be decided to be ten meters according to long vehicle type vehicle commander setting.Be installed under the roadbed, with road level.Device be arranged on road about two Side each one group.When the monolateral front and back wheel tire of overloaded vehicle reaches device, surpass setting value as it, to depress corresponding overload induction pressing plate, overload induction pressing plate compression cylinder depression bar, oil is in each oil cylinder UNICOM in parallel, and the compressing cylinder that is not subjected to is owing to there being the spacing of stop can not produce action, when pressure surpasses a setting value, oil pressure conducts to the jacking cylinder and the car blocking device oil cylinder of car arrester, and the jacking car arrester stops that vehicle moves ahead.When retrograde vehicle is come, do not contact with overload induction pressing plate, the car blocking device oil cylinder is failure to actuate, and retrograde car blocking device blocks vehicle pass-through.
This device is to adjust pressure according to the size that the quantity of doughnut and tire are pressed in lifting surface area on the overload induction pressing plate.Car arrester can allow the corresponding jacking pressure values of setting of pressure values of carrying according to the maximum of road or bridge, when vehicle pass-through, when the maximum that the jacking pressure values of car arrester exceeds road or bridge allows the pressure values of carrying, move on the car arrester jacking cylinder, played the limit for tonnage effect.As the vehicle non-overloading, then vehicle is current smoothly.
The utility model has tangible technique effect compared to existing technology.On-line monitoring weak point consuming time can confirm fast whether vehicle overloads, and accelerates not passing through of overloaded vehicle, solves the blockage problem that highway causes because of the monitoring overloaded vehicle.
