[0016] Please see Figure 1-4 This utility model provides a weighing system for transport vehicles, comprising: The base 1 has an installation cavity at its top. Several weighing sensors 12 are evenly distributed at the bottom of the installation cavity. A weighing plate 3 is installed on the top of each weighing sensor 12. The weighing plate 3 is adapted to the specifications of the installation cavity and is flush with the top surface of the base 1 in its natural state. Transition platforms 2 are fixed at both ends of the entrance and exit of the base platform 1 to facilitate the entry of transport vehicles into the base platform 1; The limiting components are liftable and can be mounted on the base 1. Several of them are evenly distributed along the outer edge of the top of the base 1. Cleaning components are installed on the top of the limiting components on both sides for cleaning the surface of the base 1 or for environmental dust reduction. Display device 9 is erected on the side of the entrance end of the base 1. A license plate recognition device 10 is installed on the top of the display device 9. The display device 9 is used to display the vehicle information recognized by the recognition device 10.

[0017] Specifically, the recognizer 10 is a license plate recognizer, and the display device 9 displays the license plate information recognized by the recognizer 10, including at least the vehicle license plate and the recognition time.

[0018] In the initial state, the limiting component retracts into the base 1. When the transport vehicle is weighed, the vehicle drives to the entrance of the base 1, the reader 10 identifies the license plate information, and the display device 9 displays the vehicle information. When the vehicle drives to the designated weighing area, the limiting component rises to intercept the vehicle and prevent it from escaping. After weighing, if the weight meets the requirements, the limiting component is released, and the vehicle leaves the base 1. If overweight or sudden weight change is detected, the limiting component remains in place, waiting for staff to confirm and handle the situation, to prevent problematic vehicles from escaping and causing losses to the production company.

[0019] After the vehicle leaves, the cleaning component cleans the platform of base 1 to prevent coal ash from falling from its top and affecting the weighing of subsequent vehicles.

[0020] Furthermore, a plurality of mounting grooves 13 are evenly provided on the outer edge of the top of the base 1. The limiting component is slidably installed in the mounting groove 13. The limiting component includes a first limiting post 7 and a second limiting post 8. The bottom of the first limiting post 7 and the second limiting post 8 are both coaxially provided with column cavities 14. A first telescopic rod 15 is installed at the bottom of the mounting groove 13. The top of the first telescopic rod 15 is fixedly connected to the bottom of the mounting groove 13. The first limiting post 7 is respectively arranged at the inlet and outlet ends of the base 1, and the second limiting post 8 is arranged on both sides of the top of the base 1. The first limiting post 7 and the second limiting post 8 are independently controlled.

[0021] Specifically, the diameter of the column cavity 14 is larger than the maximum diameter of the first telescopic rod 15. By controlling the lifting and lowering action of the first telescopic rod 15, the limiting post is controlled to limit or release the transport vehicle. When the base 1 needs to be cleaned, the second limiting post 8 rises and controls the cleaning assembly to clean the base 1.

[0022] Furthermore, a T-shaped groove 17 is provided at the top of the second limiting post 8. The horizontal section of the T-shaped groove 17 is perpendicular to the length direction of the base 1 and extends through both sides. The cleaning component is installed in the T-shaped groove 17. The cleaning component includes: T-shaped spray gun 19 is located on the upper inner side of the horizontal section of the T-shaped groove 17. The T-shaped spray gun 19 is a spray gun with a T-shaped structure, and the vertical section of the T-shaped spray gun 19 is coaxially arranged with the vertical section of the T-shaped groove 17. The end of the horizontal section of the T-shaped spray gun 19 near the inner side of the base 1 is rotatably connected to the two sides of the T-shaped groove 17 through a rotating shaft 21. The second telescopic rod 18 has a U-shaped frame 20 fixedly installed at its extended end. One end of the second telescopic rod 18 is hinged to the bottom end of the vertical section of the T-shaped groove 17, and the other end is clamped to the outer periphery of the vertical section of the T-shaped spray gun 19 through the U-shaped frame 20 and hinged thereto.

[0023] Specifically, the T-slot 17 is larger than the vertical section of the T-spray gun 19 and is designed to allow the second telescopic rod 18 to swing. The T-spray gun 19 is connected to a water supply pipe. The bottom of the inner side of the U-shaped frame 20 is spaced apart from the bottom of the vertical section of the T-spray gun 19, so as not to affect the installation of the water supply pipe.

[0024] When cleaning of the base 1 is required, the T-shaped spray gun 19 is driven to swing in a fan shape by the reciprocating lifting of the second telescopic rod 18 to clean the surface of the base 1.

[0025] Furthermore, the T-shaped spray gun 19 has a T-shaped channel inside that is adapted to its shape, and the vertical section of the T-shaped channel is connected to a water supply hose; a DC nozzle 22 is installed at the end of the horizontal section of the T-shaped channel near the rotating shaft 21, and an atomizing nozzle 23 is installed at the other end, and solenoid valves are installed on both sides of the horizontal section of the T-shaped channel.

[0026] It should be explained that the solenoid valves facilitate the opening and closing of the corresponding nozzles. When cleaning the work surface, high-pressure water is introduced into the vertical section of the T-type spray gun 19, closing one solenoid valve on one side of the atomizing nozzle 23 and opening the other solenoid valve, allowing the direct current nozzle 22 to clean the work surface. When dust suppression of the ambient air is required, the extension and retraction of the second telescopic rod 18 controls the atomizing nozzle 23 to be vertically upward, closing one solenoid valve on one side of the direct current nozzle 22 and opening the other solenoid valve, allowing the atomizing nozzle 23 to suppress dust in the ambient air. Furthermore, the T-type spray gun 19 or the water supply end is also equipped with a main valve to control the on / off flow of water to the T-type spray gun 19.

[0027] Furthermore, anti-slip strips are evenly distributed on the top of the transition platform 2.

[0028] Furthermore, the second limiting posts 8 on both sides are staggered to avoid the water flow from both sides clashing and reducing the cleaning effect.

[0029] Furthermore, between each of the second limiting posts 8 on both sides, a guide rib 4 is fixed along the width direction of the weighing plate 3, and a drainage channel corresponding to each of the cleaning components is formed between adjacent guide ribs 4, and a drainage groove 5 is longitudinally opened at both ends of the drainage channel; The base 1 has two layers of water outlet holes 6 arranged on both sides, staggered from the second limiting post 8. The water outlet holes 6 are connected to the interior of the mounting cavity. The upper layer of water outlet holes 6 is connected to the drainage trough 5 through a flexible drainage pipe 11.

[0030] It should be explained that the base surface is divided into several areas by setting the guide ridge 4 to prevent the cleaning water from flowing randomly and improve the cleaning effect. Drainage channels 5, water outlets 6 and flexible drainage pipes 11 are set in each area to quickly discharge the wastewater after cleaning.

[0031] The lower water outlet 6 discharges sewage that has seeped into the installation cavity.

[0032] Furthermore, the bottom of the mounting groove 13 is provided with a drain hole 16 facing outward to prevent sewage from seeping in and accumulating, which would affect the use of the device.

[0033] Furthermore, the display device 9 is also equipped with an alarm, which is an audible and visual alarm, to alert staff to the presence of a problematic vehicle.

[0034] Furthermore, reflective stickers are attached to the top of both the first limiting post 7 and the second limiting post 8 to mark the weighing area.

[0035] In practice, when a transport vehicle is weighed, the vehicle travels to the entrance of platform 1, where the identifier 10 identifies the license plate information and the display device 9 displays the vehicle information. When the vehicle reaches the designated weighing area, the limit component rises to prevent the vehicle from escaping. After weighing, if the weight meets the requirements, the limit component releases its limit, and the vehicle leaves platform 1. If overweight or a sudden weight change is detected, the limit component remains in place, awaiting confirmation and handling by staff to prevent problematic vehicles from escaping and causing losses to the production company. After the vehicle leaves, the cleaning component cleans the surface of platform 1 to prevent coal slag from falling from its top and affecting subsequent vehicle weighing.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
