Description

Technical Field

[0001] This utility model relates to the field of vehicle weighing technology, and in particular to a vehicle weighing device. Background Technology

[0002] Existing vehicle weighing systems typically use four trapezoidal weighing devices to measure vehicle weight. Specifically, vehicle tires roll from the inclined plane of the trapezoidal weighing device onto the weighing plate for weighing. When the weighing device is placed on a smooth, wet, or loose surface, the tires may push the weighing device as they pass over it, causing it to shift and affecting the accuracy of the weighing results. Furthermore, this could lead to equipment damage and safety hazards. Utility Model Content

[0003] The purpose of this invention is to solve the problem that weighing devices are easily pushed in slippery environments, leading to inaccurate weighing.

[0004] To solve the above problems, this utility model proposes a vehicle weighing device, including a weighing plate and ramps on two opposite sides of the weighing plate. Anti-slip studs are provided in the ramps, and the tops of the anti-slip studs extend out of the ramps to pierce the tires.

[0005] The vehicle weighing device of this utility model also includes a mounting base embedded in the ramp, with the bottom end of the anti-slip nail extending into the mounting base and the top end extending out of the ramp.

[0006] The anti-slip pin is threadedly connected to the mounting base, and the anti-slip pin can move relative to the mounting base along its axial direction to adjust the length of the anti-slip pin extending out of the ramp.

[0007] The ramp is provided with a mounting groove for accommodating the mounting base, and the mounting base is fixedly embedded in the mounting groove.

[0008] The ramp and the mounting base are respectively provided with a connected mounting hole and a connecting hole. The connecting hole is a countersunk hole used to accommodate the head of the anti-slip nail.

[0009] The vehicle weighing device of this utility model also includes a limiting block fixedly connected to the ramp, and a rack slidably connected to the limiting block. The rack passes through the limiting block and is connected to the anti-slip nail.

[0010] The vehicle weighing device of this utility model also includes a driven gear that meshes with the rack. The rack and the driven gear are respectively provided with driving teeth and driven teeth that mesh with each other. The inner surface of the driven gear is provided with an internal thread that can cooperate with the anti-slip pin. When the rack moves linearly relative to the ramp along its length direction, the rack can drive the anti-slip pin to rise and fall relative to the surface of the ramp through the driven gear.

[0011] The rack has a stop at its end, which abuts against the limiting block when the rack moves, thereby limiting the relative position of the rack and the anti-slip pin.

[0012] The anti-slip studs are arranged in an array in the ramp, with at least two rows of anti-slip studs arranged along the length of the rack on the ramp, and the rack sandwiched between at least two rows of anti-slip studs.

[0013] The anti-slip nail has a screwing part at one end away from the mounting base. The screwing part has two opposing flat parts and a pointed head located between the flat parts.

[0014] Compared with the prior art, the technical solution of this utility model has the following advantages: the vehicle weighing device of this utility model can prevent the weighing device from being pushed in a slippery environment by inserting anti-skid nails into the tire, thereby improving the accuracy of weighing.

[0030] Please see Figure 1 This utility model provides a vehicle weighing device, including a weighing plate 1 and a ramp 11. The ramp 11 is disposed on two opposite sides of the weighing plate 1 to guide the vehicle to the weighing plate 1. At least a portion of the weighing plate 1 is movable up and down relative to the ramp 11 for weighing the vehicle. Specifically, the ramp 11 includes a first ramp and a second ramp disposed on two opposite sides of the weighing plate 1. The arrangement of the first ramp and the second ramp allows the vehicle to smoothly travel along the first ramp to the weighing plate 1 and, after weighing, smoothly travel along the second ramp to the ground.

[0031] Please combine Figure 2 In one example, the ramp 11 is equipped with anti-skid studs 2 and mounting bases 3. The mounting bases 3 are embedded in the ramp 11 and extend along the width of the ramp 11. Parts of the anti-skid studs 2 pass through the ramp 11, and their position relative to the ramp 11 can be adjusted vertically. The tips of the anti-skid studs 2 can protrude from the ramp 11. When the vehicle's tires roll onto the ramp 11, the anti-skid studs 2 slightly penetrate the tires, preventing the vehicle from pushing the ramp 11 in a direction closer to or away from the weighing plate 1. This avoids displacement of the vehicle weighing device on smooth or uneven ground, improving the accuracy and stability of the weighing process.

[0032] In one example, a portion of the ramp 11 is formed as a mounting base 3, making the mounting base 3 a single piece. The top of the ramp 11 is provided with several anti-slip studs 2 protruding from the upper surface of the ramp 11 to improve the anti-slip effect. In this embodiment, the anti-slip studs 2 can be directly embedded in the ramp 11, integrally formed with the ramp 11 during its manufacturing process. Figure 2 As shown, in another example, the bottom of the ramp 11 is provided with a mounting groove 12 for accommodating the mounting base 3. The mounting base 3 is fixedly embedded in the mounting groove 12 by means of interference fit, snap-fit ​​or fastener connection, which facilitates installation and maintenance.

[0033] Specifically, the ramp 11 is provided with mounting holes 13 for installing anti-slip studs 2, and the mounting base 3 is provided with a connecting hole communicating with the mounting holes 13. In this embodiment, the connecting hole is a countersunk hole, which allows the head of the anti-slip stud 2 to be located at the opening of the countersunk hole and provides space for the anti-slip stud 2 to move up and down relative to the ramp 11. During installation, the anti-slip stud 2 can be fixed to the mounting base 3 first, and then the mounting base 3 can be installed together with the ramp 11, so that the anti-slip stud 2 protrudes from the mounting hole 13 of the ramp 11.

[0034] In one example, the anti-skid stud 2 is threadedly connected to the mounting base 3. The outer surface of the anti-skid stud 2 is provided with external threads, and the inner surface of the connecting hole of the mounting base 3 is provided with internal threads. The external threads of the anti-skid stud 2 cooperate with the internal threads in the connecting hole of the mounting base 3, which allows the anti-skid stud 2 to move relative to the mounting base 3 along the axial direction of the connecting hole, thereby adjusting the length of the anti-skid stud 2 extending out of the ramp 11 to adapt to different road conditions and tire types.

[0035] In one example, the anti-skid stud 2 is columnar, and the diameter of its end extending out of the mounting hole 13 of the ramp 11 gradually decreases in the direction away from the mounting base 3, which facilitates penetration into the tire to improve grip and thus enhance the anti-skid effect. Furthermore, the length of the portion of the anti-skid stud extending out of the ramp 11 is 1 to 3 millimeters; optionally, the length of the portion extending out of the ramp 11 is 2 or 3 millimeters. This length setting avoids substantial damage to the tire and ensures safety.

[0036] Example 1

[0037] Please continue reading. Figure 2 The vehicle weighing device of this utility model also includes a limiting block 5 and a rack 4 slidably connected to the limiting block 5. The limiting block 5 is fixedly connected to the ramp 11. Specifically, the limiting block 5 can be fixed to the surface of the ramp 11 by means of snap-fit, welding, riveting, adhesive bonding or interference fit. The limiting block 5 has a sliding hole 51 for the rack 4 to pass through. The rack 4 passes through the sliding hole 51 and is connected to the anti-slip nail 2 for adjusting the length of the anti-slip nail 2 extending out of the ramp 11.

[0038] Specifically, the rack 4 is provided with a driving tooth 41, the outer surface of the anti-slip pin 2 is provided with a driven gear 21, the outer surface of the driven gear 21 is provided with a driven tooth that cooperates with the driving tooth 41, and the inner surface of the driven gear 21 is provided with an internal thread that cooperates with the anti-slip pin 2. When the rack 4 moves linearly along the axial direction of the sliding hole 51, due to the cooperation of the driving tooth 41 and the driven tooth, the rack 4 can drive the driven gear 21 to rotate. Due to the threaded cooperation between the driven gear 21 and the anti-slip pin 2, the rotation of the driven gear 21 can drive the anti-slip pin 2 to move up and down, thereby driving the anti-slip pin 2 to rise and fall relative to the ramp 11 along the axial direction of the mounting hole 13, adjusting the length of the anti-slip pin 2 extending out of the ramp 11.

[0039] In one example, the driven gear 21 can be configured as a cylindrical structure with a wide section and a narrow section. The inner diameter of the cylindrical structure is consistent, while the outer diameter is different. The wide section is provided with the driven teeth. During installation, the narrow section is inserted into the mounting hole 13 of the ramp 11 so that it can rotate relative to the ramp 11. The wide section is located above the ramp 11 and contacts the upper surface of the ramp 11. This configuration can make the operation of the driven gear 21 more stable and can increase the meshing length between the driven gear 21 and the anti-slip pin 2, making the adjustment operation of the anti-slip pin 2 smoother.

[0040] In one example, anti-slip studs 2 are arranged in an array in the ramp 11, wherein at least two rows of anti-slip studs 2 are inserted into the ramp 11 along the length of the rack 4, and the rack 4 is sandwiched between the at least two rows of anti-slip studs 2. Both opposite sides of the rack 4 are provided with active teeth 41 that cooperate with the driven teeth, thereby improving stability.

[0041] Optionally, the rack 4 has stop portions 42 at opposite ends. The stop portions 42 are generally elongated, and their length direction is perpendicular to the length direction of the rack 4. When the rack 4 moves along its length direction, the stop portions 42 can abut against the limiting block 5 to limit the relative position of the rack 4 and the anti-slip stud 2. Furthermore, the stop portions 42 can also serve as operating parts for pushing or pulling the rack 4. In addition, a scale strip can be provided on the portion of the rack 4 near the stop portions 42. This scale strip can display the length of the anti-slip stud 2 extending out of the ramp 11, facilitating the operator to adjust the position of the rack 4 as needed.

[0042] Example 2

[0043] Please see Figure 3 and Figure 4The main difference between this embodiment and Embodiment 1 is the method of adjusting the length of the anti-skid stud 2 extending out of the ramp 11. Specifically, in this embodiment, the end of the anti-skid stud 2 away from the mounting base 3 is provided with a screwing part 22. Optionally, the screwing part 22 is flat-headed, having two opposing flat parts and a pointed head located between the flat parts. The flat parts facilitate the adjustment of the length of the anti-skid stud 2 extending out of the mounting hole 13 with the corresponding adjustment tool, and the pointed head facilitates the insertion of the anti-skid stud 2 into the vehicle tire. It should be noted that in this embodiment, the anti-skid stud 2 may not have a head, and the connecting hole in the mounting base 3 may not be a countersunk hole. During installation, the mounting base 3 is first installed into the ramp 11, and then the anti-skid stud 2 is inserted into the mounting base 3 from top to bottom through the ramp 11, thus achieving the installation of the anti-skid stud 2. When it is necessary to adjust the extension length of the anti-skid stud 2, it can be achieved by cooperating with the adjustment tool and the screwing part 22. This improves the convenience of operation and simplifies the structure.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
