Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle detection and relates to an anti-fraud device for a truck scale. Background Art
[0002] Truck scales, also known as ground scales, are the primary weighing equipment used by factories, mines, and businesses for bulk cargo measurement. Common cheating methods include placing a scale on one wheel of a truck, causing the detected weight to be less than the truck's actual weight, or placing the scale on the front of the truck while not placing the scale on the rear, thereby reducing the detected weight. Existing truck scales mostly use cameras for manual monitoring, which makes manual operation highly subjective and prone to cheating. Utility Model Content

DETAILED DESCRIPTION
[0016] The utility model is described in detail below with reference to the accompanying drawings:
[0017] like Figure 1-3As shown, a vehicle scale anti-cheating device includes a vehicle scale body 1, and a vertical limit baffle 2 is provided on each side of the vehicle scale body 1 in the length direction. The limit baffle 2 is 1.5-2m high and can effectively prevent vehicles from unilaterally entering the vehicle scale body 1 (i.e., only allowing the left or right wheels of the vehicle to enter the vehicle scale), effectively preventing vehicle cheating. A front bracket 3 is provided at one end of the vehicle scale body 1 in the length direction and a rear bracket 4 is provided at the other end. A rotatable front limit lever 5 is provided on the front bracket 3, and a rotatable front limit lever 5 is provided on the rear bracket 4. The rear limit lever 6, the front limit lever 5 and the rear limit lever 6 can limit the position of the vehicle on the scale body 1. As long as all the vehicles are driven into the scale body 1, weighing can be carried out. The front limit lever 5 and the rear limit lever 6 can effectively prevent detection when the vehicle has not entered. Specifically, the front limit lever 5 and the limit lever 6 are arranged along the width direction of the scale body 1. The front bracket 3 is provided with a first horizontally arranged shaft 7. The front limit lever 5 is fixed on the first shaft 7 and can rotate with the first shaft 7. Specifically, the front limit lever 5 is close to the end The bottom position is fixed on the first rotating shaft 7, the bottom end of the front bracket 3 is hinged with a first hydraulic cylinder 8, the top end of the first hydraulic cylinder 8 is hinged to the end of the front limit lever 5 close to the first rotating shaft 7, the top end of the first hydraulic cylinder 8 is 30-50cm away from the first rotating shaft 7, the front limit lever 5 can be driven to rotate by the extension of the first hydraulic cylinder 8, when the front limit lever 5 is in a horizontal state, it can prevent the vehicle from driving forward from the front end of the truck scale body 1 into the truck scale body 1, or from pouring out of the truck scale body 1 backward. The second rotating shaft 9 is set horizontally, and the rear limit lever 6 is fixed on the second rotating shaft 9 near the end position and can rotate with the second rotating shaft 9. The bottom end of the rear bracket 4 is hinged with a second hydraulic cylinder 10, and the top end of the second hydraulic cylinder 10 is hinged to the end of the rear limit lever 6 near the second rotating shaft 9. Similarly, the top end of the second hydraulic cylinder 10 is 30-50cm away from the second rotating shaft 9. The rear limit lever 6 can be driven to rotate by the extension and contraction of the second hydraulic cylinder 10. When the rear limit lever 6 is in a horizontal state, it can prevent the vehicle from driving out from the rear end of the truck scale body 1.
[0018] A first infrared sensor 11 is provided on the front bracket 3, and a second infrared sensor 12 is provided on the rear bracket 4. The first infrared sensor 11 is connected to a controller 13, and the controller 13 is also respectively connected to the second infrared sensor 12, the vehicle scale body 1, the first hydraulic cylinder 8 and the second hydraulic cylinder 10. The controller 13 can control the extension and retraction of the first hydraulic cylinder 8 and the second hydraulic cylinder 10, and can also control the vehicle scale body 1 to start weighing the vehicle on the vehicle scale body 1. When the head of the vehicle approaches the first infrared sensor 11 or the second infrared sensor 12, the first infrared sensor 11 or the second infrared sensor 12 can detect the position of the vehicle and send a signal to the controller 13. The controller 13 can control the first hydraulic cylinder 8 and the second hydraulic cylinder 10 to perform corresponding actions.
[0019] The usage of this utility model is as follows:
[0020] When the vehicle needs to enter the truck scale body 1 for weighing operation, due to the restriction of the limit baffle 2, the vehicle cannot enter the truck scale body 1 in a unilateral manner and can only enter from the front end of the truck scale body 1 (when the vehicle has not entered the truck scale body 1, the front limit lever 5 and the rear limit lever 6 are both in a horizontal state). When the vehicle moves to the front end of the truck scale body 1, the first infrared sensor 11 on the front bracket 3 detects the vehicle, and the first infrared sensor 11 sends a signal to the controller 13. The controller 13 controls the first hydraulic cylinder 8 to shorten, so that the front limit lever 5 rotates and lifts upward, thereby allowing the vehicle to enter the truck scale body 1 from the two limit baffles 2. The vehicle enters After the scale body 1, when the front end of the vehicle reaches the position of the rear bracket 4, the second infrared sensor 12 sends a signal to the controller 13, and the controller 13 controls the first hydraulic cylinder 8 to extend, so that the front limit lever 5 rotates downward, thereby preventing the vehicle from falling back out of the scale body 1 and completely enclosing the vehicle in the scale body 1. At this time, it means that the vehicle is already completely in the scale body 1. At this time, the controller 13 controls the scale body 1 to weigh the vehicle. At this time, weighing can ensure that the weighing test results are accurate. After the weighing test is completed, the controller 13 controls the second rotating shaft 9 to shorten, so that the rear limit lever 6 rotates and lifts upward, so that the vehicle drives out of the scale body 1.
[0021] The use of this device can effectively prevent cheating during vehicle inspection and ensure the accuracy of the inspection results.
