Background technology
At present, dynamic highway vehicle automatic weighing instrument is divided into the heavy formula of axle and car load formula by weighing mode difference.The heavy formula product of axle mainly contains fixed axle weight scale, Portable axle scale, bended plate type axle weight scale, split type axle weight scale, quartz type axle weight scale, piezoelectric film type axle weight scale etc., vehicle is in the process of sailing weighing platform into, each axle passes through weighing platform successively, weighing system is just heavily recorded the axle of each axle of vehicle, is then added the general assembly (TW) that has obtained vehicle.But due to the equal reason of position difference, pressure of tire difference, body frame structure for automotive and the articulated structure of goods on vehicle, and fill that between the each axle of axle, to have axle poor.And, in the time carrying out Dynamic Weighting, in the time that an axle of vehicle sails weighing platform into, weighing platform has a slight decline, and at this moment, the height of each axle of vehicle just has difference, this can have influence on the distribution of vehicle gravity on each axle, thus the weighing error of causing.In the time that each distance between axles of vehicle is larger, this error is less, can ignore, but when distance between axles hour, such as and fill twin shaft or and fill three axles, distance between axles is smaller, this error is just larger, very important.Just because of above-mentioned reason, the dynamic accuracy of various axle weight scales is generally lower.And relative Zhou Chongshi highway weighing apparatus, the car load measuring accuracy of car load formula highway weighing apparatus improves greatly.But the heavy weighing precision relative deficiency of the axle of car load formula highway weighing apparatus, it is axle heavy load that road is damaged to more the underlying cause, as accurate weighing axle load just cannot objective measurement vehicle road pavement destructiveness.So urgently a kind of axle weighs and all appearance of relatively high dynamic highway vehicle automatic weighing instrument of car load measuring accuracy.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, economical and practical, concurrent type frog dynamic balance that weighing precision is high, this concurrent type frog dynamic balance can be in the time that vehicle passes through by the mode of normally travelling, and the disposable while weighs single shaft weight, axle group weight and the complete vehicle weight of vehicle exactly.
For achieving the above object, the utility model adopts following technical scheme:
A kind of concurrent type frog dynamic balance, comprises weighing platform and weighing controller, and weighing platform is made up of axle weight scale platform group and car load weighing platform, on axle weight scale platform group and car load weighing platform, LOAD CELLS is all set, the output signal access weighing controller of LOAD CELLS.
Described axle weight scale platform group is at least two separate axle weight scale platform combinations that are closely adjacent to each other again, and each axle weight scale platform is measured the weight of a single shaft.
The quantity of the axle weight scale platform in described axle weight scale platform group is 2,3,4,5,6 or more.
Described axle weight scale platform group is one or more the combination in fixed axle weight scale, Portable axle scale, bended plate type axle weight scale, split type axle weight scale, quartz type axle weight scale, piezoelectric film type axle weight scale.
Along the direction of sailing into that weighs vehicle, the heavy weighing platform group of disposed axle and car load weighing platform successively.
At weighing platform both sides mounting vehicle separation vessel.
Sail direction into and be positioned at the vehicle of weighing platform tire arbiter is installed on the lane in which the drivers should pay fees.
Be embedded with coil checker being arranged in the lane in which the drivers should pay fees and being positioned in the direction that vehicle rolls away from.
Described weighing controller is arranged on a side of the lane in which the drivers should pay fees.
Described weighing controller is connected with control of intelligent terminal communication; Control of intelligent terminal be positioned at weighing platform side or Long-distance Control indoor.
The utility model adopts knockdown weighing platform, vehicle by normally travel mode by time, can be simultaneously, disposable single shaft weight, axle group weight and the complete vehicle weight that weighs exactly vehicle.The utility model is keeping under the prerequisite that car load measuring accuracy is high, greatly improve the measuring accuracy that axle is heavy and axle group is heavy, have both Zhou Chongshi highway weighing apparatus traffic efficiency height and the high feature of car load formula highway weighing apparatus measuring accuracy, also possess the features such as anti-cheating, anti-fee evasion, easy care simultaneously.
