Positioning grooves 21 are respectively opened through the front and rear sides of the strip housing 1, and the positioning slider... The 20 slides through and is installed inside the positioning slide groove 21. During use, the interaction between the positioning slider 20 and the positioning slide groove 21 enables the movable frame 11 to achieve better stability when moving, thereby ensuring that the offset detection component 4 can work stably. Openings 12 are provided on both sides of the strip housing 1, and one end of the movable frame 11 and the transmission rack 10 are movably passed through the openings 12 and extended to the outside of the strip housing 1. A spring telescopic rod 13 is fixedly installed in the middle of the side of the two movable frames 11 that are close to each other. A rubber block 14 is fixedly installed at the end of the spring telescopic rod 13 away from the movable frame 11, and the rubber block 14 is horizontally aligned with the pressure sensor 6.

[0015] Working Principle: During operation, the circular base plate 23 is first fixedly installed using mounting bolts that match the diameter of the mounting holes 24, thus achieving a fixed installation of the entire device. Then, during use, as the vehicle travels towards the weighbridge, it sequentially pushes the two movable plates 9 to move. The movable plates 9 drive the rotating shaft 8 to rotate, which in turn drives the transmission gear 7 to rotate. The transmission gear 7 then drives the transmission rack 10 to move, which in turn drives the movable frame 11 to move. The movable frame 11 causes the positioning slider 20 to slide within the positioning groove 21, ensuring better stability during movement. Simultaneously, the movable frame 11 drives the movable ring 17 to move, and the movement of the movable ring 17 adjusts the positioning... When spring 19 is compressed, the positioning spring 19 undergoes elastic deformation. Simultaneously, the movable frame 11 moves the spring telescopic rod 13, which in turn moves the rubber block 14. If both rubber blocks 14 contact the two pressure sensors 6 respectively, the vehicle does not deviate, and the alarm 3 flashes a green light without sounding. If only one rubber block 14 contacts one of the pressure sensors 6, the vehicle deviates, and the alarm 3 flashes a red light and sounds an alarm. The vehicle then moves forward away from the weighbridge, turns around, and recalibrates the weighing operation. This allows the weighbridge to better detect and alarm vehicles that have deviated from their designated positions, ensuring weighing accuracy and improving its practicality.
