Description

Technical Field

[0001] This invention relates to the field of mining equipment, and more particularly to an automatic washing device for mining vehicles. Background Technology

[0002] With the rapid development of the mining industry, mining vehicles play a crucial role in mine transportation. These vehicles often operate in dusty environments filled with limestone, coal, or metal ore, resulting in the accumulation of large amounts of mud, oil, and other pollutants on their surfaces. This not only affects the appearance of the vehicles but can also lead to mechanical failures and safety hazards. However, a series of problems exist in washing mining vehicles, hindering improvements in washing effectiveness and efficiency. First, traditional manual washing methods are time-consuming and ineffective. Due to the large size and complex structure of mining vehicles, manual washing is not only labor-intensive and resource-intensive but also often fails to thoroughly clean narrow corners and crevices. This makes it difficult to guarantee the quality of vehicle washing and increases the safety risks to personnel during the washing process. Second, the washing of mining vehicles involves significant water waste. The widely used high-pressure water guns consume a large amount of water during vehicle washing, but only a small portion is fully utilized, with a large amount of wastewater often being discharged directly without proper treatment. This not only increases water consumption but may also pollute the surrounding environment.

[0003] In addition, there are issues with wastewater treatment during the washing of mining vehicles. The wastewater generated during the washing process may contain a large amount of oil and particulate matter, which can cause environmental pollution if not properly treated.

[0004] In view of the above problems, we urgently need to improve the washing technology of mining vehicles, improve the cleaning effect, save resources and protect the environment, and contribute to the sustainable development of the mining industry. Summary of the Invention

A wheel pressure plate is installed on the top surface of the car wash platform. When a vehicle drives over the wheel pressure plate, the bottom flushing pipe rotates, allowing the first nozzle to clean hard-to-reach areas of the vehicle. This, combined with the second nozzles on the under-vehicle and side flushing pipes, provides a comprehensive cleaning, improving the cleaning effect. Furthermore, the mud pump connected to the sand filter can extract wastewater from the sump pit through a return pipe at the bottom, filter the wastewater, and reuse it through the bottom flushing pipe, effectively conserving water resources. In addition, by using the wheel pressure plate and sensors to send signals to the control console, the car wash can be automatically started and stopped without manual control, reducing labor input.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 10 The automatic washing equipment for mining vehicles shown includes a washing platform 1 with entrances and exits at the front and rear, retaining walls 2 on the left and right sides of the washing platform 1, and a sunken water collection pool 3 in the center of the washing platform 1. The bottom of the water collection pool 3 is conical and the top of the water collection pool 3 is covered with a grid 11 flush with the top surface of the washing platform 1. A vehicle under-washing pipe 31 capable of spraying water upwards is installed inside the water collection pool 3. Vehicle side-washing pipes 21 capable of spraying water to the sides of the vehicle are installed inside the retaining walls 2. A high-pressure water storage tank 4 is located on the side of the washing platform 1, connected to the vehicle under-washing pipes 31 and the vehicle side-washing pipes 21 via pipes. The inlet of the high-pressure water tank 4 is connected to a high-pressure water pump 41 via a pipe. The inlet of the high-pressure water pump 41 is connected to an external water supply pipe via a pipe. Several second nozzles 10 are evenly distributed on the undercarriage washing pipe 31 and the sidecar washing pipe 21. Specifically, the undercarriage washing pipe 31 includes a bottom main pipe 311 symmetrically arranged in the car wash platform 1 and located on the left and right sides of the water pool 3. Several water spray branch pipes 312 that penetrate into the water pool 3 are arranged sequentially and at intervals on each bottom main pipe 311. The second nozzles 10 of the undercarriage washing pipe 31 are evenly distributed on the top of the water spray branch pipes 312 that penetrate into the water pool 3.

[0031] A return water pipe 32 is connected to the bottom of the water collection tank 3 to guide the sewage out of the water collection tank 3. A mud pump 51 is installed at the outlet end of the return water pipe 32. A sand and gravel filter 5 is provided on the side of the car wash platform 1 and is connected to the outlet end of the mud pump 51. The outlet end of the mud pump 51 and the inlet end of the sand and gravel filter 5 are connected by a pipe. An overflow pipe 30 is provided on the water collection tank 3 and extends to one side of the car wash platform 1. Several support frames 34 are provided on the inner walls of the left and right sides of the water collection tank 3. A bottom flushing pipe 6 is rotatably installed on the support frame 34. Two bottom flushing pipes 6 are connected to each other by a pipe. Multiple first nozzles 61 with an angle of 45 degrees downwards towards the bottom of the water collection tank 3 are provided on the bottom flushing pipe 6 at intervals. The outlet end of the sand and gravel filter 5 is connected to the bottom flushing pipe 6 by a pipe.

[0032] The top surface of the car wash platform 1 between the water accumulation pool 3 and the retaining wall 2 is provided with slots 12. Wheel pressure plates 7, which can be pressed down by car wheels, are provided within each slot 12. Below the car wash platform 1, there is a linkage mechanism 8 that drives the bottom flushing pipe 6 to rotate, causing the first nozzle 61 to spray water obliquely upwards, when the wheel pressure plates 7 move downwards. On one side of the car wash platform 1, there is a control console 9 connected by a signal to control the operation of the high-pressure water pump 41, the high-pressure water storage tank 4 to supply water to the bottom flushing pipe 31 and the side flushing pipe 21, and the mud pump 51 to extract wastewater from the water accumulation pool 3 into the sand filter 5, and to activate the sand filter 5 to supply water to the bottom flushing pipe 6. When the wastewater level in the water accumulation pool 3 is too high, the wastewater can be discharged into a sedimentation tank through an overflow pipe 30 extending from the water accumulation pool 3 to one side of the car wash platform 1 for sedimentation and reuse.

[0033] Among them, such as Figures 7 to 10As shown, guide posts 71 extending downwards are respectively provided at both ends of the bottom of the wheel pressure plate 7. Guide sleeves 72 that can accommodate the insertion of the guide posts 71 are respectively provided at the bottom of the slot 12. Support springs 73 are respectively sleeved on the guide posts 71. Sensors 13 are provided on the inner wall of the slot 12. Sensing points 74 that can cooperate with the sensors 13 are provided at the bottom of the wheel pressure plate 7. The sensors 13 are signal connected to the control console 9. In this embodiment, the sensors 13 are Hall sensors. When the vehicle drives onto the car wash platform 1, the wheels on both sides of the vehicle will run over the wheel pressure plate 7 respectively. After the wheel pressure plate 7 moves down, the Hall sensor separates from its matching sensing point 74. The Hall sensor transmits the signal to Control console 9 starts the high-pressure water pump 41 via a preset built-in PLC and opens the solenoid valve 42 on the pipe connecting the outlet of the high-pressure water tank 4 to the undercarriage washing pipe 31 and the side washing pipe 21. The second nozzles 10 on the undercarriage washing pipe 31 and the side washing pipe 21 spray water onto the bottom and sides of the vehicle. After a certain period of washing, the controller starts the mud pump 51 to pump the sewage in the water tank 3 into the sand filter 5. After the vehicle drives away from the car wash platform 1, the support spring 73 lifts the wheel pressure plate 7. It should be noted that the initial height of the top surface of the wheel pressure plate 7 in this invention is about 2mm to 5mm higher than the top of the car wash platform 1, and the top corners at both ends of the wheel pressure plate 7 are chamfered. The sensor 13 can also be a pressure sensor installed on the guide sleeve 72.

[0034] In addition, such as Figures 3 to 10 As shown in the figure, it is clear that hinge frames 14 are arranged at intervals within the slot 12. The linkage mechanism 8 includes a first pulley 81 hinged to the hinge frame 14 via a central axle. A second pulley 82, corresponding to the first pulley 81, is arranged around the outer circumference of the bottom flushing pipe 6. A through hole 33 is formed in the side wall of the water tank 3 corresponding to the positions of the first pulley 81 and the second pulley 82. A belt 83 is fitted onto the first pulley 81, and one end of the belt 83 passes through the through hole 33 and is fitted onto the second pulley 82. A coaxial spur gear 84 is connected to one side of the first pulley 81. A rack 85 extending downwards and meshing with the corresponding spur gear 84 is provided at the bottom of the wheel pressure plate 7. As the wheel presses the wheel pressure plate 7 downwards, the rack 85 moves downwards with the wheel pressure plate 7, rotating the meshing spur gear 84. The second pulley 82 on one side of the spur gear 84 rotates synchronously, causing the bottom flushing pipe 6 to rotate via the belt 83. In this way, the angle of the bottom flushing pipe 6 will change from downward to upward. Since the inner side of the vehicle wheel hub is the easiest place for mud and sand on the mining road to accumulate, the first nozzle 61 will tilt upward and spray water towards the inner side of the vehicle wheel hub, thus cleaning the dead corners of the wheel.

[0035] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
