[0038] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0039] like Figure 1 A mobile ramp cleaning and dust suppression spray device includes a vehicle body 1, on which a water tank 3, a spraying device 2 and a pumping device 8 are installed.

[0040] The vehicle body 1 uses idle vehicles from the mine, including a front traction section (including a cab) and a rear trailer section.

[0041] The water tank 3 measures 3050mm wide x 1500mm high x 770mm and can hold approximately 3.5 tons of water. The water tank 3 is mounted on the rear chassis of the vehicle body 1 using a fixing mechanism. Specifically, as shown... Figure 1 and 3 The fixing mechanism includes two sets of I-beams 11, one at the top and one at the bottom of the water tank 3, which are welded to each other. The I-beams 11 are arranged in a left-right direction. The mechanism also includes an upper connecting plate 13 and a lower connecting plate 14. The upper connecting plate 13 is welded to the bottom of the end of the I-beam 11, and the lower connecting plate 14, corresponding to the position of the upper connecting plate 13, is welded to the side of the vehicle body 1. Both the upper connecting plate 13 and the lower connecting plate 14 have two sets of through holes, one at the top and one at the bottom. The upper connecting plate 13 and the lower connecting plate 14 are connected by a bolt and nut assembly.

[0042] Furthermore, such as Figure 1 and 2The water tank 3 has a reinforced column 6 on its outer side, enabling it to withstand greater internal pressure and lateral forces generated during shaking. Specifically, the upper end of the column 6 extends above the top of the water tank 3 and has a horizontal first connecting hole. A mounting plate 9 corresponding to the column 6 is installed on the top of the water tank 3, and the mounting plate 9 has a second connecting hole corresponding to the position of the first connecting hole. The column 6 is connected to the corresponding mounting plate 9 by bolt and nut assemblies passing through the first and second connecting holes. The lower end of the column 6 is directly or indirectly fixedly connected to the I-beam 11: the lower ends of the columns 6 located on the front and rear sides of the water tank 3 are fixedly connected to the I-beam 11 through reinforced connecting plates 12; the lower ends of the columns 6 located on the left and right sides of the water tank 3 are welded to the ends of the I-beam 11.

[0043] Furthermore, such as Figure 2 The water tank 3 is provided with two lifting plates 10 on the left and right sides respectively, and the lifting plates 10 are provided with lifting holes for easy lifting.

[0044] Furthermore, such as Figure 1 The water tank 3 has a cylindrical inlet at its top, and a cover plate 4 is hinged to the inlet. A U-shaped groove is formed on the side of the cover plate 4 away from the hinge. A threaded rod passes through this U-shaped groove at the top of the water tank 3, and a T-shaped handle is mounted on the threaded rod. The lower end of the handle is threaded into the threaded rod to press the cover plate 4 tightly. A circular opening is also provided in the middle of the cover plate 4, through which the inlet end of the water outlet pipe 5 is inserted into the water tank 3. The gap between the water outlet pipe 5 and the circular opening is small, preventing water from overflowing due to shaking.

[0045] like Figure 1 and 4 The spraying device 2 includes two sets of symmetrically arranged L-shaped pipes 2-1, with the horizontal portion of the L-shaped pipes 2-1 located at the top of the water tank 3 and the vertical portion located on the side of the water tank 3. Spray nozzles 2-2 are installed on both the horizontal and vertical portions of the L-shaped pipes 2-1. The L-shaped water pipes are obtained by bending straight pipes, with both ends sealed by welding, and water inlets are provided on the pipes.

[0046] Preferably, the spraying device 2 is installed at the front end of the water tank 3. A connecting rod 15 is fixed to the side wall and top of the water tank 3 by welding, and a pipe clamp is connected to the outer end of the connecting rod 15 by welding. The L-shaped pipe 2-1 is fixed to the pipe clamp. The spraying device 2 is located at the front end of the water tank 3 and behind the cab, which facilitates the driver's observation of the spraying situation through the rearview mirror and also, to some extent, prevents the sprayed water from directly falling onto the windshield and affecting normal driving.

[0047] The pumping device 8 includes an engine 8-1 and a water pump 8-2.

[0048] The power output shaft of the engine 8-1 is connected to the input shaft of the water pump 8-2 via a transmission mechanism (a transmission belt in this embodiment).

[0049] The engine 8-1 is a diesel engine (with its own diesel tank; a single fill of the tank allows for 6 hours of normal operation, fully meeting the design requirements of the equipment), and it uses compression ignition for starting. Figure 5 The start button SB1 and the coil of relay KA1 are connected in series between the positive and negative terminals of a 12V power supply. The normally open contact of relay KA1 is connected in series between the positive and negative terminals of a 12V power supply and the chuck 8-1-1-1 inside the starter motor 8-1-1 of engine 8-1. The normally open contact of chuck 8-1-1-1 is then connected in series between the positive and negative terminals of a 12V power supply and the rotor coil 8-1-1-2 of starter motor 8-1-1. When starting, pressing the start button SB1 located in the cab energizes relay KA1, which in turn energizes chuck 8-1-1-1, thereby energizing rotor coil 8-1-1-2. Starter motor 8-1-1 drives crankshaft to rotate, causing the engine piston to move and compress air. Simultaneously, diesel fuel is injected, achieving compression ignition conditions. Engine 8-1 ignites successfully and begins self-sustaining operation. At this point, start button SB1 can be released.

[0050] Furthermore, such as Figure 4 The outlet pipe 5 is connected to the inlet of the water pump 8-2. The outlet of the water pump 8-2 is connected to the left and right pipelines respectively via a three-way device. A left water valve 16 is installed on the left pipeline, and a right water valve 17 is installed on the right pipeline. The left and right pipelines are connected to the left and right L-shaped pipelines 2-1 respectively. The water pump 8-2 is equipped with a nitrogen accumulator (water pump model: 3WZ-90A, with built-in accumulator) to stabilize the pressure and prevent pressure fluctuations from affecting the cleaning and spraying effect. A safety valve is also connected to the outlet of the water pump 8-2. The pressure relief outlet of the safety valve is connected to the water tank 3 via a return pipeline. The return pipeline can be connected to the water tank 3 from the top of the water tank 3, or it can be connected to the inside of the water tank 3 through a separate opening at the cover plate 4.

[0051] Furthermore, both the left water valve 16 and the right water valve 17 are located in the driver's cab of the vehicle body 1. During installation, water is led from the outlet of the water pump 8-2 to the driver's cab through a hose, and after the water valves are installed, they are connected to the spray device 2 through a hose.

[0052] Furthermore, the pumping device 8 is installed at the rear of the vehicle body 1, located behind the water tank 3. Above the pumping device 8 is an inclined baffle 7 fixedly disposed relative to the vehicle body 1. The front edge of the inclined baffle 7 is higher than the rear edge, which is used to block the pumping device 8 and quickly divert the falling water to the rear.

[0053] Furthermore, a windshield wiper is provided on the outer side of the windshield of the driver's cab of the vehicle body 1, and the control button SB2 for the windshield wiper is located inside the driver's cab. Figure 5 In the control circuit, the coils of relays KA2 and KA3 are connected in parallel and then connected in series with button SB2 between the positive and negative terminals of the 12V power supply. The normally open contact of relay KA2 is connected in series with the left wiper motor M1 between the positive and negative terminals of the 12V power supply, and the normally open contact of relay KA3 is connected in series with the right wiper motor M2 between the positive and negative terminals of the 12V power supply. After pressing control button SB2, both wiper motors start rotating simultaneously, which in turn drives the wiper blades to reciprocate through the intermediate transmission mechanism. The specific structure of the wipers is based on existing technology and will not be described in detail here.

[0054] Before starting work, fill water tank 3 with water, then cover it with cover plate 4 and adjust the water outlet pipe 5 (a mark can be left to ensure the lower end of the water outlet pipe 5 is at the bottom of water tank 3). During operation, the operator drives the vehicle from inside the cab and presses the start button SB1. As needed, open the left valve and / or the right valve. The engine 8-1 starts, driving the water pump 8-2 to work, and high-pressure water begins spraying, completing the cleaning and dust suppression operation. During operation, the operator can press control button SB2 to activate the windshield wipers to clear water from the windshield.

[0055] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
