Description

Technical Field

[0001] This invention relates to a coal bunker cleaning device, specifically a device capable of thoroughly cleaning the interior of a coal bunker. Background Technology

[0002] Coal Bunker Management and Challenges: Coal bunkers are a crucial component in the storage and transportation of coal. In traditional coal bunkers, coal easily clumps together, forming bridging or "bridges," hindering its smooth flow and impacting normal operation. Furthermore, the complex internal environment of coal bunkers easily generates dust pollution, and frequent entry for cleaning by operators poses significant safety hazards. The demand for coal bunker cleaning is high. Currently, traditional methods rely on manual labor using high-pressure water hoses to spray the inner walls of the bunker. This method is not only inefficient but also labor-intensive and carries significant safety risks. Summary of the Invention

[0003] The purpose of this invention is to provide a coal bunker cleaning device that can effectively reduce labor intensity and safety risks.

[0004] To achieve the above objectives, the technical solution adopted by this invention is as follows: A coal bunker cleaning device includes a rotary gear platform, a drive gear, a drive motor, and a vertical gantry. The drive gear is connected to the shaft of the drive motor and meshes with the rotary gear platform. The drive motor drives the rotary gear platform to rotate through the drive gear. The vertical gantry is mounted on the rotary gear platform, and the rotary gear drives the vertical gantry to rotate. A lifting platform is mounted on the vertical gantry, a lower clamp is mounted on the rotary gear platform, and an upper clamp is mounted on the lifting platform.

[0005] Furthermore, the vertical gantry is provided with a drive assembly for driving the lifting platform to move up and down. The drive assembly includes a lead screw motor, a lead screw, and a connecting seat. The lead screw motor is mounted on the vertical gantry via a fixed seat. One end of the lead screw is connected to the lead screw motor, and the other end is rotatably connected to the vertical gantry. The connecting seat is disposed on the lead screw and connected to the lifting platform.

[0006] Furthermore, the vertical gantry is provided with slide rails on both sides, and the lifting platform is provided with sliders on both sides, with the sliders mounted on the slide rails.

[0007] Furthermore, the rotary gear platform is provided with a working hole, and the coal bunker is provided with a clearance hole to facilitate the passage of the drill rod. The working hole is located above the clearance hole; the drill rod passes through the working hole and the clearance hole in sequence to enter the interior of the coal bunker.

[0008] Furthermore, the upper clamp has the same structure as the lower clamp. The upper clamp includes a first telescopic cylinder and a second telescopic cylinder. Both the first telescopic cylinder and the second telescopic cylinder are connected to clamping blocks, and the clamping blocks are provided with grooves that are adapted to the drill rod.

[0009] Furthermore, the lifting platform is provided with through holes to facilitate the passage of drill rods.

[0010] Furthermore, it also includes a hoisting assembly and a mobile frame, with the hoisting assembly positioned above the mobile frame; the rotary gear platform, drive gear, drive motor, and vertical gantry are all mounted on the chassis of the mobile frame; the hoisting assembly includes a hook, which is used to connect to the crossbeam of the mobile frame to drive the mobile frame to move.

[0011] Furthermore, the hoisting assembly also includes a track and multiple sets of rollers, each set of rollers being configured on the track, the rollers being rotatably connected to the connecting plates via a pivot, and connecting rods connecting adjacent connecting plates.

[0012] Furthermore, the hook is connected to the electric hoist, and the electric hoist is hinged to the connecting plate.

[0013] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention utilizes the coordinated operation of a lifting platform, an upper clamp, and a lower clamp to automatically connect and deliver drill rods into the coal bunker. During connection, the lower clamp grips the drill rod below, while the upper clamp grips the drill rod to be installed. The upper clamp then connects the drill rod to the connecting seat. After alignment, the upper clamp releases the drill rod, allowing for its installation. The rotary gear platform, driven by a motor, rotates, causing the drill rod in the coal bunker to rotate, enabling the high-pressure nozzles fixed to the drill rod to effectively clean the interior of the coal bunker 360°.

[0018] like Figure 1 and Figure 2As shown, a coal bunker cleaning device includes a rotary gear platform 1, a drive gear 2, a drive motor 3, a vertical gantry 4, a hoisting assembly, and a movable frame 11. The drive gear 2 is connected to the shaft of the drive motor 3 and meshes with the rotary gear platform 1. The drive motor 3 drives the rotary gear platform 1 to rotate through the drive gear 2. The vertical gantry 4 is mounted on the rotary gear platform 1, and the rotary gear platform 1 drives the vertical gantry 4 to rotate. A lifting platform 5 is mounted on the vertical gantry 4. A lower clamp is mounted on the rotary gear platform 1, and an upper clamp is mounted on the lifting platform 5. A drive assembly for driving the lifting platform 5 to rise and fall is mounted on the vertical gantry 4. The drive assembly includes a lead screw motor 6, a lead screw 7, and a connecting seat 8. The lead screw motor 6 is mounted on the vertical gantry 4 through a fixed seat. One end of the lead screw 7 is connected to the lead screw motor 6, and the other end is rotatably connected to the vertical gantry 4. The connecting seat 8 is disposed on the lead screw 7 and connected to the lifting platform 5. Both the drive motor 3 and the lead screw motor 6 are connected to the hydraulic station. When connecting the drill rod, the drill rod to be installed is first clamped by the upper clamp, ensuring the center lines of the drill rod on the upper clamp and the drill rod on the lower clamp are aligned. After installation, the upper clamp re-clamps the drill rod, the lower clamp releases it, and the lifting platform 5 moves into the coal bunker under the action of the lead screw motor 6. Once it reaches the target position or the target position of the drill rod, the lower clamp re-clamps the drill rod, the upper clamp releases it, and the lifting platform 5 returns to the top of the vertical gantry 4 under the action of the lifting platform 5, ready for the installation of the next drill rod. The high-pressure nozzle enters the coal bunker synchronously with the drill rod, cleaning the inner wall of the coal bunker from top to bottom. During the cleaning process, the drive gear 2 drives the rotary gear platform 1 to rotate, causing the high-pressure nozzle to rotate 360° within the coal bunker, achieving a comprehensive cleaning of the coal bunker.

[0019] The vertical gantry 4 is equipped with slide rails 9 on both sides, and the lifting platform 5 is equipped with sliders 10 on both sides, with the sliders 10 mounted on the slide rails 9. The slide rails 9 and sliders 10 ensure stable operation of the lifting platform 5 during operation, preventing the lead screw 7 from jamming due to vibration or tilting. The rotary gear platform 1 has a working hole, and the coal bunker has an obstacle hole to facilitate the passage of the drill rod; the working hole is located above the obstacle hole. The drill rod passes through the working hole and the obstacle hole sequentially into the coal bunker. The lifting platform 5 has a through hole to facilitate the passage of the drill rod.

[0020] like Figure 3As shown, the upper clamp has the same structure as the lower clamp. The upper clamp includes a first telescopic cylinder 11 and a second telescopic cylinder 12. Both the first telescopic cylinder 11 and the second telescopic cylinder 12 are connected to clamping blocks 13. Each clamping block 13 has a groove 14 that fits the drill rod. The groove 14 fits the outer wall of the drill rod, ensuring that the center of the groove 14 coincides with the center of the drill rod, preventing the drill rod from shifting during installation and causing jamming.

[0021] To improve the automation level of this device, built-in sensors can be installed in the coal bunker to monitor data such as the coal accumulation location, density, and humidity. The rotation speed of the drive motor 3 and the rotary gear platform 1 is set according to the coal accumulation location, aiming to target the coal accumulation location and avoid dust dispersion caused by excessive disturbance. When the sensors confirm no significant accumulation in the coal bunker, the gear disc gradually stops rotating, and the motor power is cut off. The sliding cleaning mechanism returns to its initial position, and simultaneously, the hydraulic clamp changes from a clamping state to a slack state to unload the rod, which is then disassembled section by section for collection and later use.

[0022] like Figure 4 As shown, the hoisting assembly is positioned above the movable frame 11; the rotary gear platform 1, drive gear 2, drive motor 3, and vertical gantry 4 are all mounted on the chassis of the movable frame 11; the hoisting assembly includes a hook 22, which is connected to the crossbeam of the movable frame 11 to move the movable frame 11. The hoisting assembly also includes a track 23 and multiple sets of rollers, each set of rollers being configured on the track 23. The rollers are rotatably connected to the connecting plate 24 via a rotating shaft, and a connecting rod 25 connects adjacent connecting plates 24. The hook 22 is connected to an electric hoist 26, which is hinged to the connecting plate 24. After the target coal bunker is cleaned, it needs to be replaced. The hook 22 is lowered using the electric hoist 26 so that it hooks onto the crossbeam of the movable frame 11, and then lifted by the electric hoist 26. The rollers move in the track 23, thus moving the movable frame 11. The mobile frame 11 will drive the rotary gear platform, drive gear, drive motor and vertical gantry to move until it reaches the next coal bunker that needs to be cleaned. The hook 22, under the action of the electric hoist 26, lowers the mobile frame 11 to the top of the coal bunker. Finally, the hook 22 is removed from the crossbeam of the mobile frame 11 and retrieved, completing the purpose of replacing and cleaning the coal bunker.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
