Description

Technical Field

[0001] The utility model relates to the technical field of additional devices for vehicle weighbridges, in particular to a dust-proof device for heavy and light vehicle weighbridges. Background Art

[0002] In thermal power plants, heavy and light vehicle weighbridges are important devices for weighing bulk materials such as coal. However, during actual use, due to the gap problem between the heavy and light vehicle weighbridges and the foundation, sundries such as coal dust, particulate matter, and even winter snow often enter the inside of the weighing body, thus affecting the normal operation of the weighing sensor. These sundries not only reduce the weighing accuracy but also increase the risk of sensor damage, thereby affecting the stability and reliability of the entire metering system. In addition, to remove these sundries, manual cleaning is usually required regularly, which not only increases the additional labor cost but also may affect the normal production progress due to frequent maintenance.

[0003] Although there are some designs on the market currently to prevent sundries from entering the inside of heavy and light vehicle weighbridges, such as simple shielding strips or dust-proof curtains, these designs often have problems such as inconvenient installation, easy damage, or poor dust-proof effect. Therefore, it has become an urgent problem to develop a device that can effectively prevent sundries from entering the gap between the heavy and light vehicle weighbridge and the base, and is easy to install and has a low maintenance cost. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a dust-proof device for heavy and light vehicle weighbridges. To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A dust-proof device for heavy and light vehicle weighbridges is installed at the gap between the weighbridge and the base of the weighbridge, and includes a fixing plate, a dust-proof leather, and several expansion screws. A plurality of mounting holes are evenly formed in the fixing plate. The dust-proof leather is laid under the fixing plate and covers the gap between the weighbridge and the base. The expansion screws are arranged in the mounting holes, and the fixing plate fixes the dust-proof leather on the base through the expansion screws.

[0006] Furthermore, a plurality of bottom plates are fixedly connected to the end of the base at the gap. A support rod is hinged to the top end of the bottom plate, and a spring is fixedly connected between the support rod and the bottom plate. The support rod is laid under the dust-proof leather.

[0007] Furthermore, a groove corresponding to the fixing plate is formed in the dust-proof leather. The fixing plate is flush with the dust-proof leather. A concave hole matched with the expansion screw is formed in the fixing plate, and the expansion screw is flush with the fixing plate.

[0008] Furthermore, the fixing plate is made of stainless steel flat bar.

[0009] Further, the fender is made of a rubber backing plate or a PVC backing plate.

[0010] Further, a wear-resistant strip is clamped at the end of the fender above the car beam.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By providing a fender at the gap between the heavy and light car beams and the base, it can effectively prevent sundries such as coal dust, particulate matter, and winter snow from entering the scale body, ensuring the normal operation of the weighing sensor, reducing the influence of sundries on the sensor, significantly improving the accuracy and stability of metering. At the same time, it avoids frequent manual cleaning work, reducing maintenance costs and manpower consumption;

[0013] 2. Adopting the combination method of the fixing plate and the expansion screw makes the installation process of the device simple and fast, facilitating the installation and replacement by on-site operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following further describes the technical solutions in the present utility model in conjunction with the drawings and embodiments.

[0019] Please refer to Figure 1 、 Figure 2 As shown, a dust-proof device for heavy and light car beams is installed at the gap between the car beam 1 and the base 2 of the car beam 1, and includes a fixing plate 3, a fender 4 and a plurality of expansion screws 5. A plurality of mounting holes are evenly formed on the fixing plate 3. The fender 4 is laid under the fixing plate 3 and covers the gap between the car beam 1 and the base 2. The expansion screws 5 are arranged in the mounting holes, and the fixing plate 3 fixes the fender 4 on the base 2 through the expansion screws 5.

[0020] Its core working principle is: using the structure of the fixing plate 3 with the fender 4 fixed on the base 2 of the heavy and light car beam 1, and fixed through the expansion screw 5 to effectively prevent sundries such as coal dust and particulate matter from entering the scale body, ensuring the working accuracy and efficiency of the weighing sensor.

[0021] In another embodiment, please refer to Figure 2 As shown, a plurality of bottom plates 6 are fixedly connected to the end of the base 2 located at the gap. A support rod 7 is hinged to the top end of the bottom plate 6. A spring 8 is fixedly connected between the support rod 7 and the bottom plate 6. The support rod 7 is placed under the fender 4. The support rod 7 is used to lift the fender 4 when the weighbridge 1 is not in use, facilitating the cleaning of the residue under the fender 4.

[0022] In this embodiment, please refer to Figure 2 As shown, a groove corresponding to the fixing plate 3 is formed on the fender 4. The fixing plate 3 is flush with the fender 4. A concave hole matching the expansion screw 5 is formed on the fixing plate 3. The expansion screw 5 is flush with the fixing plate 3. This avoids interfering with the driving of the vehicle and facilitates the vehicle to smoothly drive onto the weighbridge 1.

[0023] In this embodiment, please refer to Figure 1 As shown, the fixing plate 3 is made of a stainless steel flat bar. The fender 4 is made of a rubber backing plate or a PVC backing plate. This increases the durability of the dust-proof device.

[0024] In this embodiment, please refer to Figure 1 As shown, a wear-resistant strip 9 is clamped on the end of the fender 4 located above the weighbridge 1. This increases the durability of the fender 4 and reduces the replacement frequency.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
