Description

Technical Field

[0001] This application relates to the field of weighbridge device technology, and in particular to a sunken double weighbridge device. Background Technology

[0002] A sunken weighbridge is a weighing device that integrates multiple intelligent systems, mainly used for vehicle weighing and cargo measurement. The core working principle of a sunken weighbridge is based on the perfect integration of gravity and mechanics. When a vehicle drives onto the weighing platform, the force of gravity causes the elastic body inside the sensor to deform. This deformation is captured by the strain gauge bridge attached to the surface of the elastic body and converted into an electrical signal proportional to the weight. After signal amplification, analog-to-digital conversion, and other processing steps, the precise value is finally displayed on the screen.

[0003] Currently, in sunken weighbridges, the weighing surface is level with the ground. As freight vehicles pass by, dirt and debris carried on the wheels fall onto the weighbridge. However, traditional weighbridges do not have a cleaning device for the weighing surface, so the spilled or stuck dirt and debris usually need to be cleaned manually, which adds unnecessary burden to the staff. Therefore, an improvement has been made to a sunken double weighbridge device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a sunken double weighbridge device, which overcomes the shortcomings of the prior art and aims to solve the problem that the traditional weighbridge does not have a cleaning device for the weighing surface, and requires manual cleaning of dirt and debris that fall on the weighbridge surface.

[0005] To achieve the above objectives, this application provides the following technical solution: a sunken dual weighbridge device, comprising a ground surface, on which two mounting slots are symmetrically formed, and a weighbridge device body is embedded in each of the two mounting slots. The weighbridge device body is at the same height as the ground surface. A positioning frame is fixedly installed on the upper surface of the ground between the two weighbridge device bodies. A lead screw is rotatably connected inside the positioning frame. A drive motor for driving the lead screw to rotate is fixedly installed on the side wall of the positioning frame. A moving block is threaded onto the outer surface of the lead screw. A movable slot is formed inside the movable block. A rotating rod is arranged inside the movable slot. A rotary motor for driving the rotating rod to rotate is fixedly installed on the top of the movable block. A cleaning brush plate is provided at the bottom of the rotating rod.

[0006] By adopting the above technical solution and setting up two independent weighbridge main bodies, the weighing of vehicles entering and exiting can be carried out separately, realizing bidirectional weighing function, which can improve weighing efficiency and reduce waiting time. The drive motor drives the lead screw to rotate. Since the lead screw and the moving block are threadedly connected, the rotation of the lead screw can drive the moving block to move. The rotation motor drives the rotating rod to adjust the position of the cleaning brush plate, and rotates the cleaning brush plate to move it above the weighbridge main body. That is, the device achieves mechanical cleaning without manual intervention through the synergistic effect of lead screw transmission and rotating cleaning brush plate, which significantly reduces labor costs.

[0007] As a preferred technical solution of this application, the end of the rotating rod away from the moving block is provided with an insertion groove, the cleaning brush plate is slidably inserted into the insertion groove, and the cleaning brush plate is fixedly connected to the rotating rod by fixing screws.

[0008] By adopting the above technical solution, the cleaning brush plate and the rotating rod are assembled together through the cooperation between the insertion slot and the fixing screw, so that the cleaning brush plate can be disassembled for cleaning.

[0009] As a preferred technical solution of this application, a guide rod is slidably inserted inside the movable block, and both ends of the guide rod are fixedly connected inside the positioning frame.

[0010] By adopting the above technical solution, the guide rod, through its sliding engagement with the moving block, restricts the moving block to move only along the axis of the guide rod, thus avoiding offset or vibration caused by the lateral torque generated by the screw drive.

[0011] As a preferred technical solution of this application, the number of the drive motor, rotating rod, insertion slot and cleaning brush plate are all set in pairs and correspond one-to-one, and the lower surface of the cleaning brush plate is in contact with the upper surface of the weighbridge device body.

[0012] By adopting the above technical solution, the symmetrically designed cleaning brush plates can be used alternately without affecting the weighing on the other side during cleaning.

[0013] As a preferred technical solution of this application, the positioning frame, lead screw and guide rod are all stainless steel components, and the drive motor and rotary motor are both waterproof motors.

[0014] By adopting the above technical solutions, the positioning frame, lead screw, and guide rod made of stainless steel are highly corrosion-resistant, will not be corroded by rainwater, and have a long service life. Both the drive motor and the rotary motor are waterproof motors, ensuring that neither of them will short-circuit due to rain.

[0015] As a preferred technical solution of this application, a fence is fixedly installed on the upper surface of the ground outside the mounting groove, and the space formed by the fence surrounds the main body of the weighbridge device. Barrier gates and warning signs are symmetrically installed on the upper surface of the ground on the left and right sides of the main body of the weighbridge device.

[0016] By adopting the above technical solutions, the enclosed space formed by the fence can isolate the main working area of ​​the weighbridge device, preventing personnel from accidentally entering or vehicles from deviating. The linkage between the barrier gate and the main body of the weighbridge device can realize orderly management of vehicle entry and exit, and warning signs indicate the direction of entry and exit.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this invention, by setting two independent weighbridge main bodies, the weighing of vehicles entering and exiting can be carried out separately, realizing bidirectional weighing function, which can improve weighing efficiency and reduce waiting time. The drive motor drives the lead screw to rotate. Since the lead screw and the moving block are threadedly connected, the rotation of the lead screw can drive the moving block to move. The rotation motor drives the rotating rod to adjust the position of the cleaning brush plate, and rotates the cleaning brush plate to move it above the weighbridge main body. That is, this device achieves mechanical cleaning without manual intervention through the synergistic effect of lead screw transmission and rotating cleaning brush plate, which significantly reduces labor costs.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a sunken dual weighbridge device, including a ground surface 1. Two mounting slots 2 are symmetrically formed on the upper surface of the ground surface 1. Weighbridge device bodies 3 are embedded inside each of the two mounting slots 2. The weighbridge device bodies 3 are at the same height as the ground surface 1. A positioning frame 4 is fixedly installed on the upper surface of the ground surface between the two weighbridge device bodies 3. A lead screw 5 is rotatably connected inside the positioning frame 4. A drive motor 6, which drives the lead screw 5, is fixedly installed on the side wall of the positioning frame 4. A moving block 8 is threaded onto the outer surface of the lead screw 5. A movable groove 9 is formed inside the movable block 8. A rotating rod 10 is installed inside the movable groove 9. A rotary motor 11, which drives the rotating rod 10, is fixedly installed on the top of the movable block 8. The bottom of the weighbridge is equipped with a cleaning brush plate 12. During use, by setting up two independent weighbridge main bodies 3, the weighing can be carried out separately for entry and exit, realizing bidirectional weighing function, which can improve weighing efficiency and reduce waiting time. The drive motor 6 drives the lead screw 5 to rotate. Since the lead screw 5 and the moving block 8 are threadedly connected, the rotation of the lead screw 5 can drive the moving block 8 to move. The rotary motor 11 drives the rotating rod 10 to rotate and adjust the position of the cleaning brush plate 12, rotating and moving the cleaning brush plate 12 to the top of the weighbridge main body 3. That is, the device achieves mechanical cleaning without manual intervention through the synergistic effect of the lead screw 5 transmission and the rotation of the cleaning brush plate 12, which significantly reduces labor costs.

[0028] In this embodiment, as Figure 2-4 As shown, the end of the rotating rod 10 away from the moving block 8 has an insertion groove 13. The cleaning brush plate 12 is slidably inserted into the insertion groove 13, and the cleaning brush plate 12 is fixedly connected to the rotating rod 10 by the fixing screw 14. In use, the cleaning brush plate 12 and the rotating rod 10 are assembled together by the cooperation between the insertion groove 13 and the fixing screw 14, so that the cleaning brush plate 12 can be disassembled for cleaning.

[0029] In this embodiment, as Figure 2As shown, a guide rod 7 is slidably inserted inside the movable block 8. Both ends of the guide rod 7 are fixedly connected inside the positioning frame 4. During use, the guide rod 7, through its slidable insertion with the movable block 8, limits the movable block 8 to move only along the axial direction of the guide rod 7, thus preventing offset or vibration caused by the lateral torque generated by the lead screw 5.

[0030] In this embodiment, as Figure 2 and 4 As shown, the number of drive motor 6, rotating rod 10, insertion slot 13 and cleaning brush plate 12 are all set in pairs and correspond one-to-one. The lower surface of the cleaning brush plate 12 is in contact with the upper surface of the weighbridge device body 3. In use, the symmetrically designed cleaning brush plates 12 can be used alternately, and the weighing on the other side will not be affected during cleaning.

[0031] In this embodiment, as Figure 2 As shown, the positioning frame 4, lead screw 5, and guide rod 7 are all stainless steel components, and the drive motor 6 and rotary motor 11 are both waterproof motors. During use, the positioning frame 4, lead screw 5, and guide rod 7, made of stainless steel, are highly corrosion-resistant and will not be corroded by rainwater, resulting in a long service life. The drive motor 6 and rotary motor 11 are both waterproof motors, ensuring that neither of them will short-circuit due to rain.

[0032] In this embodiment, as Figure 1 As shown, a fence 17 is fixedly installed on the upper surface of the ground 1 outside the mounting groove 2, and the space formed by the fence 17 surrounds the main body 3 of the weighbridge device. On the upper surface of the ground 1, a barrier arm 15 and a warning sign 16 are symmetrically installed on the left and right sides of the main body 3 of the weighbridge device. When in use, the enclosed space formed by the fence 17 can isolate the working area of ​​the main body 3 of the weighbridge device, preventing personnel from accidentally entering or vehicles from deviating. The barrier arm 15 and the main body 3 of the weighbridge device are linked to realize orderly management of vehicle entry and exit. The warning sign 16 indicates the direction of entry and exit.

[0033] The working principle of this utility model is as follows: When using the sunken double weighbridge device of this application, the barrier gate 15 and the weighbridge device body 3 are linked to realize the orderly management of vehicle entry and exit. The weighbridge device body 3 weighs the vehicles. After a period of use, when it is necessary to clean the weighbridge device body 3, the rotary motor 11 is started to drive the rotating rod 10 to rotate and adjust the position of the cleaning brush plate 12. The cleaning brush plate 12 is rotated and moved to the top of the weighbridge device body 3. Then, the drive motor 6 drives the lead screw 5 to rotate, so that the moving block 8 reciprocates along the axis of the guide rod 7. That is, the moving block 8 can drive the cleaning brush plate 12 to move and clean the upper surface of the weighbridge device body 3.
