Description

Weighbridge wheel detecting system

Technical Field

The utility model relates to a weighbridge wheel detecting system belongs to weighbridge check out test set technical field.

Background

The weighbridge is also called as a truck scale, is a widely applied truck weighing device, and for enterprises of mineral exploitation, metallurgy, manufacturing and the like, raw materials or products need to be transported into and out of the enterprises by the truck, and the weight difference between the weight of a cargo-carrying vehicle and the weight of an empty vehicle is generally adopted to measure the weight of cargos carried by the truck. Some drivers often adopt some cheating means to intentionally change the weighing result of the vehicle in order to gain illegal benefits, such as weighing the front vehicle earlier when weighing the front vehicle, weighing the rear vehicle incompletely when weighing the rear vehicle to increase the weighing weight, or intentionally stopping the vehicle outside the boundary of the weighbridge to reduce the weighing weight when weighing the vehicle. The prevention of the cheating behaviors relates to the problem of position detection of the vehicle on the wagon balance, a detection device is required to be used for detecting whether the vehicle is located within the wagon balance boundary line, if the vehicle is detected to be out of range, weighing is invalid or not carried out, a driver moves the vehicle to a legal range and then weighs the vehicle, and therefore economic loss caused by the cheating behaviors of enterprises is reduced.

As shown in fig. 1, in the conventional wagon balance vehicle position detection, a pair of infrared transmitting and receiving devices are respectively installed at two ends of a wagon balance boundary line by using a set of infrared sensing device, and a connecting line of the infrared transmitting and receiving devices is located above the wagon balance boundary line. The detection device has a simple structure, the infrared light is positioned above a weighbridge weighing boundary line, and strict requirements are imposed on the installation position of equipment; in addition, the infrared sensing device essentially belongs to a point sensor, and has certain limitation, because the wheel position is taken as a basis for judging whether the vehicle is out of range, if the mounting height of the sensing device is higher than the chassis height of the vehicle, the head and the carriage can shield infrared light to cause misjudgment; if the installation height of the sensing device is lower than the height of the chassis of the vehicle, if a cheating driver intentionally makes infrared light beams pass through gaps among wheels when parking the vehicle, the receiving end still can receive the infrared light, and detection errors are caused.

Therefore it is necessary to provide a weighbridge wheel detecting system, through the slide control of the linear slide rail device realization infrared sensing device of mutual disposition, enlarge the point sensor to line sensor, thereby realize the accurate judgement of wheel position on the weighbridge, on the one hand can the limited application range that improves the weighbridge like this, as long as the wheel can be on the weighbridge entirely, even if the automobile body exceeds the weighbridge weighing range and also can weigh, on the other hand can effectively prevent some cheating actions of weighing, if the preceding car is not totally down the pound in order to increase the weight of weighing or the vehicle is in order to reduce the weight of weighing in the outer end when weighing, effectively reduce the economic loss that the enterprise consequently class cheats and leads to.
