Description

Technical Field

[0001] This invention relates to the field of monorail powder coating technology, specifically to a monorail track powder coating and fabric application device. Background Technology

[0002] In the underground coal mining sector, monorails have become important transportation equipment due to their flexibility and efficiency. However, under conditions of steep gradients, heavy loads, and complex track layouts, they are prone to slippage and brake failure due to insufficient friction between the drive wheels and the track.

[0003] To solve this problem, existing technologies involve spraying friction-enhancing powder onto the track surface and using processes such as high-voltage electrostatic spraying and plasma spraying to form a wear-resistant coating, thereby increasing the coefficient of friction. This, combined with an automated powder spraying vehicle, enables stable operation on the monorail and effectively ensures the driving and braking forces of the monorail.

[0004] However, in actual operation, when the monorail powder coating vehicle passes through track joints, drop steps, or curves, it will experience severe bumps and swaying due to sudden changes in track structure, which will destroy the stability of the powder coating system. Specifically, the powder in the material chamber is prone to bridging, layering, or agglomeration due to vibration. During air blowing, the gas flow rate and pressure fluctuations will be aggravated, which will eventually cause the powder to be sprayed out too much during bumps, resulting in uneven coating thickness and affecting the adhesion rate, which seriously restricts the reliability of the powder coating resistance enhancement effect. Summary of the Invention

[0005] The purpose of this invention is to provide a monorail track powder spraying and fabric application device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a monorail suspension track powder spraying and spreading device, comprising a machine body and a suspension rail body, the machine body being connected to the suspension rail body via several moving wheels, a connecting frame being fixedly connected to the surface of the machine body, a fixing frame being fixedly connected to one side of the connecting frame, and a spraying structure for spraying powder onto the track being installed on the surface of the fixing frame; A discharge structure is provided on one side of the fixed frame. The discharge structure includes a material box, a material pipe is fixedly connected to the bottom of the material box, a material distribution plate is fixedly connected to the bottom of the material pipe, a feeding block is fixedly connected to the bottom of the material distribution plate, the feeding block is connected to the fixed frame through a conveying pipe, a material distribution component is provided in the material distribution plate, a stabilizing component is provided in the material box, the stabilizing component includes a sleeve passing through the material box, a pressure plate is fixedly connected to the bottom of the sleeve, the size of the pressure plate is adapted to the inner diameter of the material pipe, and the sleeve is connected to the material box through spring A.

[0007] Preferably, an air pipe is inserted inside the sleeve, the air pipe is connected to the material box via a fixing rod, and the top of the air pipe extends outside the material box.

[0008] Preferably, a connecting rod is fixedly connected to the top of the sleeve, and a baffle adapted to the top opening of the trachea is fixedly connected to the top of the connecting rod.

[0009] Preferably, the material distribution assembly includes a motor fixedly connected to the bottom of the material distribution plate, a rotating shaft fixedly connected to the output end of the motor, the rotating shaft passing through the material distribution plate, and a plurality of material feeding plates fixedly connected to the surface of the rotating shaft. The bottom of the material distribution plate has a through hole, which communicates with the inside of the feeding block.

[0010] Preferably, the inner wall of the dispensing tray is fixedly connected with protrusions, and the dispensing plate is made of soft material.

[0011] Preferably, the spraying structure includes two powder spraying blocks fixedly connected to the surface of the fixed frame. The shape of the powder spraying blocks is adapted to the hanging rail body, and a plurality of nozzles are fixedly connected to the side of the powder spraying blocks near the hanging rail body.

[0012] Preferably, the stabilizing component includes a closing plate that slides within the feed block, the size of the closing plate being adapted to the inner wall size of the feed block, and the closing plate being connected to the feed block by a plurality of springs B.

[0013] Preferably, an air inlet pipe is fixedly connected to the end of the feed block away from the conveying pipe, and the air inlet pipe is connected to an external air supply device.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a pressure plate. When encountering track joints or drop steps, the vibration of the machine body causes the pressure plate to move downward and compress spring A, sealing the connection between the material box and the material pipe, thereby pausing the feeding and sealing from the feeding end, thus avoiding the problem of excessive powder spraying caused by the machine body shaking.

[0015] This invention features a material distribution component. The rotating material feeding plate continuously discharges powder from the through hole. The material feeding plate is deformed by the extrusion of the protrusion and moves closer to the adjacent material feeding plate to compress the powder, reducing agglomeration and improving the uniformity of powder spraying. Furthermore, during the rebound vibration process after the material feeding plate passes the protrusion, the powder is further dispersed, reducing agglomeration.

[0016] This invention directly sets a closing plate at the feed block. When the machine vibrates, the closing plate and spring B work together to seal the connection between the feed block and the conveying pipe, thus sealing from the conveying end and reducing the problem of excessive powder feeding and uneven powder spraying during the vibration process.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention discloses a monorail track powder spraying and fabric application device, such as... Figure 1-5 As shown, the device includes a body 1 and a rail body 12. The body 1 is connected to the rail body 12 via several moving wheels 11. The moving wheels 11 are rotatably connected to the surface of the body 1 and are distributed on both sides of the rail body 12, abutting against the rail body 12. The body 1 can be driven by its own power source, such as a motor 321, to move on the surface of the rail body 12, or it can be moved by other powered rail vehicles. A connecting frame 2 is fixedly connected to the surface of the body 1. A fixing frame 21 is fixedly connected to one side of the connecting frame 2. The shape of the fixing frame 21 is adapted to the rail body 12. A spraying structure for spraying powder onto the rail is installed on the surface of the fixing frame 21. The movement of the body 1 on the surface of the rail body 12 drives the spraying structure to continuously spray powder onto the surface of the rail body 12.

[0021] In this embodiment, a discharge structure is also included, disposed on one side of the fixed frame 21. The discharge structure includes a material box 3, which holds powder, such as metal-based, ceramic-based, or composite-based powder. A material pipe 31 is fixedly connected to the bottom of the material box 3, and the material pipe 31 communicates with the inside of the material box 3. A distribution plate 32 is fixedly connected to the bottom of the material pipe 31, and the distribution plate 32 communicates with the inside of the material pipe 31. A feed block 221 is fixedly connected to the bottom of the distribution plate 32, and the feed block 221 communicates with the inside of the distribution plate 32. The feed block 221 is connected to the fixed frame 21 through a conveying pipe 22, and both ends of the conveying pipe 22 are fixedly connected to the feed block 221 and the fixed frame 21, respectively. The feed pipe 31, the conveying pipe 22, and the fixed frame 21 are all interconnected. A distribution component is provided in the distribution plate 32, and a stabilizing component is provided in the material box 3 for use in the machine body. 1. To stabilize the amount of powder when passing through bumpy areas, the stabilizing component includes a sleeve 331 inserted inside the material box 3. A pressure plate 332 is fixedly connected to the bottom of the sleeve 331. The size of the pressure plate 332 is adapted to the inner diameter of the material pipe 31. The sleeve 331 is connected to the material box 3 by a spring A333. Under normal conditions, the pressure plate 332 is a certain distance away from the material pipe 31. At this time, the powder in the material box 3 can enter the distribution plate 32 through the material pipe 31. An air inlet pipe 222 is fixedly connected to the end of the feed block 221 away from the conveying pipe 22. The air inlet pipe 222 is connected to an external air supply device. After the powder entering the distribution plate 32 is distributed by the distribution component, it is carried away from the distribution plate 32 by the air inlet pipe 222. It passes through the feed block 221, the conveying pipe 22 and the fixing frame 21 in sequence, and is then sprayed onto the track surface by the spraying structure.

[0022] Specifically, when the machine body 1 passes through the bumpy area, steps, or seams of the track, the machine body 1 will move up and down due to the bumps. At this time, the pressure plate 332 moves up and down synchronously under the action of inertia, and compresses the spring during the downward movement. The downward movement of the pressure plate 332 will temporarily block the connection between the material box 3 and the material pipe 31, thereby temporarily stopping the feeding of powder and reducing the problem of excessive powder spraying in a short time due to the bumps, which wastes powder and causes uneven powder spraying. After the track becomes smooth, the spring A333 rebounds and pulls the sleeve 331 and the pressure plate 332 at its bottom to move up to the initial position, thus not affecting the continued powder spraying.

[0023] An air pipe 33 is installed inside the sleeve 331. The upper and lower ends of the air pipe 33 are connected. The air pipe 33 is connected to the material box 3 through a fixing rod 336. The two ends of the fixing rod 336 are fixedly connected to the air pipe 33 and the material box 3 respectively. The top of the air pipe 33 extends outside the material box 3. By setting the air pipe 33, the air pressure inside the material pipe 31 is balanced with the air pressure outside the material box 3, thereby avoiding the problem that the powder cannot be fed due to air pressure.

[0024] Furthermore, a connecting rod 334 is fixedly connected to the top of the sleeve 331, and a baffle 335 adapted to the top opening of the air pipe 33 is fixedly connected to the top of the connecting rod 334. By setting the baffle 335, when the pressure plate 332 moves down due to bumps and drives the sleeve 331 down, it will simultaneously drive the baffle 335 at the top of the connecting rod 334 down. At the same time as the pressure plate 332 briefly blocks the connection between the material box 3 and the material pipe 31, the baffle 335 briefly blocks the top opening of the air pipe 33, so that the material pipe 31 and the space inside the distribution plate 32 are isolated from the external space, and the powder will continue to fall under atmospheric pressure.

[0025] The material distribution assembly includes a motor 321 fixedly connected to the bottom of the material distribution plate 32. The motor 321 is a servo motor. The output end of the motor 321 is fixedly connected to a rotating shaft 322. The rotating shaft 322 passes through the material distribution plate 322, and a plurality of material-pulling plates 323 are fixedly connected to the surface of the rotating shaft 322. The material-pulling plates 323 are arc-shaped. The bottom of the material distribution plate 32 has a through hole 325, which communicates with the inside of the feeding block 221. The size of the through hole 325 is approximately equal to the distance between the two material-pulling plates 323.

[0026] Specifically, the output of motor 321 drives the rotating shaft 322 to rotate, which in turn causes several material feeding plates 323 in the material distribution plate 32 to rotate. The material feeding plates 323 evenly subdivide the powder falling from the material pipe 31 and drop it into the bottom feed block 221 through the through hole 325. Airflow is continuously introduced through the air inlet pipe 222 to evenly transport the powder entering the feed block 221.

[0027] Furthermore, the inner wall of the dispensing disc 32 is fixedly connected with a protrusion 324, and the feeding plate 323 is made of a soft material, such as a rubber plate or a silicone rubber plate, which has a certain toughness and can undergo a certain deformation and bending when the feeding plate 323 contacts the protrusion 324.

[0028] Specifically, when the rotating shaft 322 drives the material feeding plate 323 to rotate and convey the powder between the two material feeding plates 323, the material feeding plate 323 rotates to the position of the protrusion 324. Due to the intrusion of the protrusion 324, it will deform accordingly, causing the material feeding plate 323 to move towards its adjacent material feeding plate 323 and squeeze the space between the two material feeding plates 323. This effectively squeezes the powder between the two material feeding plates 323, crushing the agglomerated powder lumps and reducing the problem of uneven spraying caused by powder agglomeration. Furthermore, as the material feeding plate 323 continues to move and passes the protrusion 324, the material feeding plate 323 will rebound and vibrate due to its own elasticity, further impacting and vibrating the powder, making the agglomerated powder easier to break.

[0029] The spraying structure includes two powder spraying blocks 211 fixedly connected to the surface of the fixing frame 21. The shape of the powder spraying blocks 211 is adapted to the shape of the hanging rail body 12, and a number of nozzles 212 are fixedly connected to the side of the powder spraying blocks 211 near the hanging rail body 12. The nozzles 212 are cyclone pneumatic nozzles or spiral pneumatic nozzles. The airflow carries the powder from the fixing frame 21 into the powder spraying blocks 211 and sprays it out through the number of nozzles 212, spraying it onto the surface of the hanging rail body 12.

[0030] In one parallel embodiment, the stabilizing component includes a closing plate 4 that slides within the feed block 221. The closing plate 4 is located at the feed block 221, which is the powder conveying position. The size of the closing plate 4 is adapted to the inner wall size of the feed block 221, and the closing plate 4 is connected to the feed block 221 by several springs B41. With the setting of the closing plate 4, when the machine body 1 passes through the track bump area, steps, or joints, the machine body 1 will move up and down due to the bumps, which will drive the closing plate 4 to move up and down. When the closing plate 4 moves down, it compresses the springs B41, so that the closing plate 4 can temporarily close the connection between the feed block 221 and the conveying pipe 22, and temporarily control the powder from the conveying end to reduce the phenomenon of excessive powder spraying caused by bumps.
