Description

Technical Field

[0001] The utility model relates to the technical field of truck scale limit, in particular to a truck scale adopting an intermediate limit device structure. Background Art

[0002] As a device that can quickly and accurately weigh the load weight of large vehicles, the truck scale meets the needs of aspects such as trade settlement, inventory management, and transportation cost accounting. Especially in the fields of bulk commodity trading, port logistics, and road transportation, the truck scale is widely used, which can ensure the fairness of transactions and the efficiency of logistics. The working principle of the truck scale is to use a weighing sensor to convert the weight of the vehicle into an electrical signal, and then convert the electrical signal into a digital or analog signal through a display instrument for display.

[0003] Before weighing a vehicle, check whether all components of the truck scale are normal, including sensors, wiring, instrument display, etc. If there is a fault, check whether the scale body is flexible and whether there is deformation, damage, etc. Then turn on the display instrument of the truck scale and let it preheat for a period of time after power on. After the vehicle stops stably, the driver needs to turn off the engine of the vehicle, and then accurately record the gross weight of the vehicle. After confirming the weight, the vehicle can leave.

[0004] In the process of weighing a vehicle with the existing truck scale, if the wind is strong, it will cause the vehicle to shake on the scale platform, thus affecting the final weighing result and accuracy. Moreover, when weighing a vehicle, if the vehicle body is not at the center of the truck scale, it will also lead to inaccurate final total results of the vehicle. Generally, a large number of nuts are used to fix between the truck scale and the pedal. However, when disassembling and replacing the pedal, a large amount of time is required for removal, and a large number of nuts will result in low disassembly efficiency. Content of the Utility Model

[0005] In view of the above problem that if the wind is strong, it will cause the vehicle to shake on the scale platform

[0006] If the vehicle body is not at the center of the truck scale, it will also lead to inaccurate final total results of the vehicle, the present utility model is proposed.

[0007] To solve the above technical problems, the present utility model provides the following technical solutions: A weighbridge with an intermediate limiting device structure, comprising: a weighbridge main body and a pedal.

[0023] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings in the specification. Embodiment 1

[0024] Referring to Figures 1-4 , which is the first embodiment of the present utility model, a weighbridge adopting a middle limiting device structure is provided, including: a weighbridge main body 1 and a pedal 2. The pedal 2 is installed at the vertical surfaces on both sides of the weighbridge main body 1. A fixing device 3 is also provided on the upper surface of the weighbridge main body 1, and the fixing device 3 includes: a rectangular plate 4. A hydraulic telescopic rod 5 is installed on the upper surface of the rectangular plate 4. A pair of U-shaped frames 6 are provided directly above the rectangular plate 4. First threaded rods 7 are provided at the inner rings of the U-shaped frames 6. A pair of symmetric rectangular blocks 8 are provided directly above the rectangular plate 4. A rectangular notch is penetrated and opened at the vertical surface of the rectangular block 8. A second threaded rod is rotatably connected to the vertical surface inside the rectangular notch, and the second threaded rod penetrates through the rectangular block 8 and is connected to the rotating rod on the gear 15. A moving block 9 is slidably connected inside the rectangular notch. An arc-shaped clamp 10 is provided at the vertical surface of the moving block 9 away from the hydraulic telescopic rod 5.

[0025] A U-shaped block 11 is slidably connected to the upper surface of the rectangular plate 4. A chute is opened at the intersection of the U-shaped block 11 and the rectangular plate 4. A ball is provided inside the chute and is connected to the U-shaped block 11. A rectangular groove is also provided at the vertical surface of the U-shaped block 11 away from the hydraulic telescopic rod 5. A convex block 14 is inside the rectangular groove, and there is a sliding relationship between them. A driving motor 12 is provided directly above one of the U-shaped frames 6. L-shaped support plates are provided on both sides of the driving motor 12. The output end of the driving motor 12 is fixedly connected to a transmission wheel 13. One of the threaded rods 7 penetrates through the U-shaped frame 6, and a transmission wheel is also fixedly connected to the rod body outside the U-shaped frame 6 of the threaded rod 7. A belt is provided between the pair of transmission wheels. A convex block 14 is also provided at the vertical surface of the rectangular block 8 close to the hydraulic telescopic rod 5, and the convex block 14 is sleeved on the rod body of the first threaded rod 7. A rotating rod is provided at the vertical surface of the rectangular block 8, and a gear 15 is fixedly connected to the rod body of the rotating rod. A pair of toothed plates 16 are also provided on the upper surface of the rectangular plate 4, and the several guide blocks of the toothed plate 16 are in a meshing relationship with the teeth of the gear 15.

[0026] During use, first let the vehicle drive towards the center of the weighbridge main body 1 through the pedal 2, and then start the hydraulic telescopic rod 5. Since the telescopic rod body of the hydraulic telescopic rod 5 is connected to the U-shaped block 11, and there is a sliding relationship between the U-shaped block 11 and the rectangular plate 4, as the hydraulic telescopic rod 5 pushes, the U-shaped block 11 will move. As the rectangular block 8 moves, because a rotating rod is also provided at the vertical surface of the rectangular block 8, and a gear 15 is fixedly connected to the rod body of the rotating rod, and the rod body of the second threaded rod is connected to the rotation, and there is an intermeshing relationship between the toothed plate 16 and the gear 15, so as the moving block 8 moves, a pair of arc-shaped clamps 10 will approach each other, thus clamping the vehicle tire. Then, adjust according to the height of the vehicle tire. First, start the drive motor 12. Since the output end of the drive motor 12 is connected to the first threaded rod 7, the output end of the drive motor 12 is also fixedly connected to a transmission wheel 13, and one of the threaded rods 7 passes through the U-shaped frame 6, and a transmission wheel is also fixedly connected to the rod body of the threaded rod 7 outside the U-shaped frame 6. A belt is provided between a pair of transmission wheels. As the drive motor 12 drives, a pair of first threaded rods 7 will rotate. Since the intersection of the first threaded rod 7 and the convex block 14 is provided with a round hole, and a threaded groove is provided at the arc surface inside the round hole, and there is an intermeshing relationship between the threaded groove and the thread on the rod body of the first threaded rod 7, so as the first threaded rod 7 rotates, the convex block 14 will rise. Since a lifting groove is also provided at the arc surface between a pair of arc-shaped clamps 10, and a roller is slidably connected inside the lifting groove, and the roller is also connected to a pressing plate. At this time, the arc-shaped clamps 10 have clamped the tire. As a pair of arc-shaped clamps 10 rise, the pressing plate on the arc-shaped clamps 10 will, under the action of friction, remain unchanged, but the arc-shaped clamps 10 will continue to rise and temporarily fix the middle part of the tire. Embodiment 2

[0027] Refer to Figure 1 and 5 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a pair of arc-shaped protection frames 17 are also installed on the upper surface of the weighbridge main body 1, a positioning block 18 is also provided at the vertical surface of the pedal 2 close to the weighbridge main body 1, and several docking grooves with the same spacing are provided on the upper surface of the positioning block 18. Several fixing blocks 19 are slidably connected to the upper surface of the weighbridge main body 1. A pair of rectangular mounting plates 20 are provided at the vertical surfaces of the fixing blocks 19, and a mounting groove 21 is provided at the intersection of the positioning block 18 and the weighbridge main body 1.

[0028] When disassembling and replacing the pedal 2, first remove the arc-shaped protective frame 17 installed on the upper surface of the vehicle scale body 1, and then remove the nut on the rectangular mounting plate 20 using a wrench or other tool. After removing the nut, the fixing block 19 can be directly pulled out, because before the fixing block 19 is pulled out, it passes through the positioning block 18 through the docking groove and clamps the positioning block 18. After the fixing block 19 is pulled out, the pedal 2 can be pulled out for replacement.

[0029] The remaining structures are the same as those of Example 1.
