Description

Technical Field

[0001] This invention relates to the field of ship loader technology, and in particular to a ship loader chute cleaning device. Background Technology

[0002] The top of the chute connects to the tail of the material conveyor belt on the ship loader. After leaving the conveyor belt, the material moves downwards through the chute, primarily addressing the problem of dust dispersion during powder loading and unloading. The chute is generally a telescopic structure, ensuring its bottom is close to the bottom of the forks. Telescopic chutes typically consist of a canvas cover and a support ring. When different bulk materials pass through the chute, some residue remains on the canvas. If chemical or grain particles are mixed, they may react during transport or storage, causing material damage or spoilage. When cleaning tubular spaces, rotating brushes are generally used to clean the interior. When the chute is long, a traction rope is needed to control the rotating brush's movement within the chute. Rigid connecting rods are prone to breakage; therefore, the traction rope controls the up-and-down movement of the rotating brush to clean the tubular space. However, the rotating brush device is prone to self-rotation during operation, causing the traction rope to become tangled and knotted. This prevents the device from maintaining a relatively stable state with the pipe wall, which can affect the cleaning effect or the stability of its own structure. Therefore, it is necessary to optimize the chute cleaning device. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a ship loader chute cleaning device, which solves the problem that when the chute is long, using a traction rope to control the rotating brush device can easily cause the device controlling the rotating brush device to rotate on its own.

[0004] According to an embodiment of the present invention, a cleaning device for a ship loader chute is provided. The cleaning device is disposed inside the chute of the ship loader and includes a first motor, a second motor, a movable frame, a first traction rope, two or more annular brushes, and a transmission assembly. The top of the chute protrudes upward and is higher than the position communicating with the ship loader body. The movable frame is a cylindrical structure and is disposed inside the chute and coaxially. The first motor is horizontally fixedly disposed at the top of the chute. One end of the first traction rope is fixedly connected to the output shaft of the first motor, and the other end of the first traction rope extends downward and is fixedly connected to the center of gravity of the movable frame. The annular brushes are sleeved on the outside of the movable frame and rotatably connected to the movable frame. The second motor is fixedly disposed to the movable frame. The transmission assembly is geared to the second motor and the annular brushes. The second motor causes the annular brushes to rotate in both forward and reverse directions simultaneously through the transmission assembly.

[0005] The technical principle of this invention is as follows: when the movable frame moves up and down inside the chute, the second motor drives two or more annular brushes to rotate in opposite directions to clean the chute. The force of the opposite rotation will cancel out the reaction force of the chute on the annular brushes, thereby preventing the movable frame from rotating on its own.

[0006] Preferably, the transmission assembly includes a first gear, a fixed ring is fixedly disposed inside the annular brush, the end faces of adjacent fixed rings are provided with annular teeth, and there is a gap between adjacent annular teeth. The first gear is horizontally disposed between two adjacent annular teeth and meshes with two annular teeth at the same time. The end of the first gear is rotatably connected to the movable frame.

[0007] Preferably, the second motor is vertically fixed inside the movable frame, and a second gear is provided on the output shaft of the second motor. An internal gear is provided on the inner side of one of the fixed rings, and the second gear and the internal gear mesh. When the second motor rotates, it drives one of the fixed rings to rotate, and the adjacent fixed rings will rotate in the opposite direction.

[0008] Preferably, the assembly also includes a third gear, a telescopic rod, a rotating shaft, fan blades, and two sealing plates. The telescopic rod is vertically arranged and fixedly connected to the movable frame. The rotating shaft is vertically arranged and has gears on its outer wall. The rotating shaft and the telescopic rod are coaxial and rotatably connected to the movable section of the telescopic rod. The rotating shaft extends downward to the outside of the movable frame. The fan blades are fixedly arranged at the bottom end of the rotating shaft. The third gear, the second gear, and the rotating shaft are all geared together. The rotating shaft of the third gear is rotatably connected to the movable frame.

[0009] Preferably, the first traction rope is provided with two parallel ropes, which are symmetrically arranged with respect to the axis of the movable frame, and the two first traction ropes and the axis of the movable frame are coplanar.

[0010] Preferably, the device also includes a third motor, a second traction rope, and a permanent magnet chuck. The third motor is fixedly mounted on the top of the chute. A second take-up reel is provided in the axial direction of the third motor. One end of the second traction rope is fixedly connected to the second take-up reel, and the other end of the second traction rope passes through the movable frame and extends downward to be fixedly connected to the permanent magnet chuck.

[0011] Preferably, the bottom of the movable frame is provided with a protective cover that slides vertically; the protective cover and the rotating shaft are rotatably connected and axially fixed; the fan blades are disposed inside the protective cover; the outer wall of the protective cover has a vertical guide tube, the second traction rope passes through the center of the guide tube, and the guide tube and the protective cover are fixedly connected.

[0012] Compared with the prior art, the present invention has the following advantages: it keeps the posture of the movable frame stable when it moves up and down the chute, and the center of the movable frame and the center of the chute remain relatively stable, so that the bristles of the annular brush can make uniform contact with the side wall of the chute, ensuring the cleaning effect.

[0021] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 , 2As shown, this embodiment of the invention proposes a cleaning device for a ship loader chute. The ship loader is used to transfer various bulk materials, and this cleaning device is used to clean various bulk materials fixed on the chute. The cleaning device is installed inside the chute 25 of the ship loader, which is composed of a barrel-shaped canvas and several parallel support rings 8. The cleaning device includes a first motor 4, a second motor 16, a movable frame 5, a first traction rope 3, two or more annular brushes 11, and a transmission assembly. The top of the chute 25 protrudes upward and is higher than the position communicating with the ship loader body 1, so as to install other equipment. When the ship loader is transporting materials normally, the cleaning device moves to the top space of the chute 25 to avoid affecting the normal transport of materials. The movable frame 5 is a cylindrical frame structure made of a lightweight material, such as aluminum alloy. The movable frame 5 is located inside the chute 25 and is coaxial, with a gap between the outer side of the movable frame 5 and the inner wall of the chute 25. The first motor 4 is horizontally fixedly mounted on the top of the chute 25. One end of the first traction rope 3 is fixedly connected to the output shaft of the first motor 4, and the other end of the first traction rope 3 extends downward and is fixedly connected to the center of gravity of the movable frame 5 to prevent the movable frame 5 from tilting. In this embodiment, a first take-up reel 2 is provided on the top of the chute 25. One end of the first traction rope 3 is fixedly connected to the first take-up reel 2 to achieve a fixed connection with the output shaft of the first motor 4. In this embodiment, two first traction ropes 3 are provided, and therefore two first take-up reels 2 are correspondingly provided. The two first take-up reels 2 are coaxial and connected to each other through a first transmission shaft 22. The annular brush 11 is sleeved on the outside of the movable frame 5 and rotatably connected to the movable frame 5. The second motor 16 is fixedly mounted inside the movable frame 5. The transmission assembly and the second motor 16 and the annular brush 11 are geared together. The second motor 16 enables the annular brush 11 to rotate in both forward and reverse directions simultaneously through the transmission assembly.

[0023] In this embodiment, the annular brush 11 provided on the chute 25 includes two first annular brushes 28 and one second annular brush 29. The length of the second annular brush 29 is the sum of the lengths of the other two first annular brushes 28, so that the resistance of forward and reverse rotation cancels each other out.

[0024] like Figure 2 , 6As shown, preferably, the transmission assembly includes a first gear 14, and a fixing ring 13 is fixedly disposed inside the annular brush 11. The fixing ring 13 is made of high-strength plastic, such as polycarbonate. The end faces of adjacent fixing rings 13 are provided with annular teeth 30, with a gap between adjacent annular teeth 30. The first gear 14 is rotatably disposed between two adjacent annular teeth 30, and the rotation axis of the first gear 14 is horizontal. The first gear 14 meshes with two annular teeth 30 simultaneously, and the rotation axis of the first gear 14 is rotatably connected to the movable frame 5. When one of the fixing rings 13 rotates, the first gear 14 drives the adjacent fixing ring 13 to rotate, changing the rotation direction of the adjacent fixing ring 13. In this embodiment, the first gears 14 are symmetrically arranged, so that the movable frame 5 maintains a balanced state.

[0025] like Figure 2 As shown, preferably, the second motor 16 is vertically fixed inside the movable frame 5. A second gear 15 is provided on the output shaft of the second motor 16, and an internal gear is provided on the inner side of one of the fixed rings 13. The second gear 15 meshes with the internal gear. In this embodiment, an automatic take-up device is provided at the top of the chute 25, so that the wire supplying power to the second motor 16 can extend or retract as the movable frame 5 moves up and down, avoiding wire tangling. The automatic take-up device is electrically connected to the first motor 4, and a controller is provided inside the automatic take-up device, so that the operation of the take-up device is synchronized with the height of the movable frame 5.

[0026] like Figure 2 As shown, preferably, it also includes a third gear 10, a telescopic rod 12, a rotating shaft 27, fan blades 6, and two sealing plates 26. The telescopic rod 12 is vertically arranged and fixedly connected to the movable frame 5. The telescopic rod 12 is fixed to the top of the movable frame 5, and the fixed section of the telescopic rod 12 is fixedly connected to the movable frame 5. The rotating shaft 27 is vertically arranged and has gears on its outer wall. The rotating shaft 27 is coaxial with the telescopic rod 12 and rotatably connected to the movable section of the telescopic rod 12. The rotating shaft 27 extends downward to the outside of the movable frame 5. The rotatable connection between the rotating shaft 27 and the movable frame 5 improves stability. The fan blades 6 are fixedly arranged at the bottom end of the rotating shaft 27, and the axis of the fan blades 6 is coaxial with the axis of the rotating shaft 27. A fourth gear is arranged on the rotating shaft 27, and the fourth gear, the third gear 10, and the second gear 15 mesh sequentially. The rotating shaft of the third gear 10 is rotatably connected to the movable frame 5. When the second motor 16 works, it drives the second gear 15 to rotate, and the second gear 15 sequentially drives the third gear 10 and the rotating shaft 27, causing the fan blades 6 to rotate. When the fan blade 6 rotates, it causes the airflow in the chute 25 to move downward, carrying the dust particles that have been detached from the chute 25 downward and discharged downward.

[0027] When the cleaning device is not working, in order to reduce the height of the top of the chute 25 protruding upwards, the fan blades 6 rise upwards to avoid the fan blades 6 obstructing the movement of materials on the material transport route.

[0028] like Figure 4 As shown, preferably, two first traction ropes 3 are provided, and the two first traction ropes 3 are symmetrically arranged with respect to the axis of the movable frame 5, and the axes of the two first traction ropes 3 and the movable frame 5 are coplanar. The more traction ropes provided, the better the torque of the movable frame 5's rotation can be resisted, and the safety and stability of the movable frame 5 during operation can be improved.

[0029] like Figure 3 , 4 As shown in Figure 5, preferably, the system also includes a third motor 18, a second traction rope 9, and a permanent magnet chuck 20. The third motor 18 is fixedly mounted on the top of the chute 25. A second take-up reel 24 is axially mounted on the third motor 18. One end of the second traction rope 9 is fixedly connected to the second take-up reel 24, and the other end of the second traction rope 9 passes through the movable frame 5 and extends downwards to be fixedly connected to the permanent magnet chuck 20. The movable frame 5 has a hole through which the second traction rope 9 passes, and the second traction rope 9 and the movable frame 5 are fitted with a clearance. The second take-up reel 24 is located on the top of the chute 25, and one end of the second traction rope 9 is fixedly connected to the second take-up reel 24. The output shaft of the third motor 18 is coaxial with and fixedly connected to the second take-up reel 24. When cleaning the chute 25, the third motor 18 drives the second take-up reel 24 to rotate, lowering the permanent magnet chuck 20 at the bottom of the second traction rope 9 to the bottom, corresponding to the chute 25 extending to its longest position. The bottom of the permanent magnet chuck 20 is fixedly connected to the metal base plate 21. When the movable frame 5 moves up and down, it remains coaxial with the chute 25 to prevent damage to the chute 25 caused by misalignment. In this embodiment, two second traction ropes 9 are provided. A second drive shaft 23 is provided between the two second take-up reels 24. There is a height difference between the first drive shaft 22 and the second drive shaft 23 to avoid interference.

[0030] This embodiment uses a manual permanent magnet chuck 20. The operator only needs to manually turn on the permanent magnet chuck 20 to generate magnetic force to fix it to the metal base plate 21, so that the second traction rope 9 can be kept taut to stabilize the posture of the movable frame 5.

[0031] like Figure 1 , 2As shown in Figure 7, preferably, the bottom of the movable frame 5 is provided with a protective cover 7 that slides vertically. The protective cover 7 is rotatably connected to the rotating shaft 27 and is axially fixed. The fan blade 6 is disposed inside the protective cover 7. The outer wall of the protective cover 7 has a vertical guide tube 17. The second traction rope 9 passes through the center of the guide tube 17, and the guide tube 17 is fixedly connected to the protective cover 7. When the second traction rope 9 passes the position of the fan blade 6, it avoids the fan blade 6 and the second traction rope 9 from coming into contact and cutting the second traction rope 9. When the cleaning device is not working, the protective cover 7 and the fan blade 6 retract synchronously and rest on the top of the chute 25.

[0032] 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 it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
