Description

Technical Field

[0001] This utility model relates to the technical field of dust collectors for overhead suction trolleys, and more specifically, it relates to a dust collector for overhead suction trolleys with an automatic dust removal function. Background Technology

[0002] In the field of overhead suction trolley dust collectors, the timeliness of equipment cleaning, the convenience of pipeline connection, and the reliability of structural connection are key factors affecting the performance. However, the current overhead suction trolley dust collectors on the market still have many technical defects in practical applications. These problems not only affect the operating efficiency of the equipment, but may also reduce the service life and operational reliability of the system.

[0003] The primary problem is the significant lack of timeliness in equipment cleaning. Existing material suction methods have significant defects: First, dust and metal shavings easily accumulate on the surface of strong magnets, affecting their magnetic properties; second, contaminants on the surface of the suspended items gradually accumulate on the strong magnets, reducing their adsorption force; third, the accumulation of contaminants after long-term use not only affects the suction effect but may also cause items to fall off due to weakened magnetism. These shortcomings of traditional material suction methods not only reduce the equipment's working efficiency but may also lead to safety accidents, failing to meet the continuous operation requirements of modern industrial production.

[0004] More notably, the ease of pipe connection in dust collection devices is a major flaw. Existing pipe connection methods have significant operational problems: First, traditional connection structures are too simple and lack quick assembly / disassembly mechanisms; second, connecting and disconnecting pipes requires cumbersome procedures, increasing maintenance time; third, insufficient sealing at the connection points not only leads to gas leakage but may also cause a decrease in system efficiency due to seal failure. These shortcomings of traditional connection methods not only increase maintenance costs but also prolong equipment downtime, affecting production efficiency.

[0005] Most critically, the structural connection reliability is severely inadequate. Although some equipment has achieved convenient operation by adding quick-connect devices, this design still has obvious defects: First, the connection structure is too simple and lacks a reliable locking mechanism; second, during system operation, air pressure fluctuations inside the pipeline will continuously impact the connection; third, the vibration generated during equipment operation may cause the connection structure to loosen. This structural design deficiency not only affects the sealing performance of the system, but may also cause safety hazards due to pipeline connection detachment, reducing the operational reliability of the dust collection system.

[0031] Please see Figures 1-5A dust collector for a material suction crane with automatic dust removal function includes a mounting frame 1. A dust collection device is installed on the outside of the mounting frame 1. The dust collection device includes a dust collector 2, a movable frame 3, a connecting pipe 4, and a suction port 5. The dust collector 2 is located on both sides of the mounting frame 1, the connecting pipe 4 is located on the outside of the mounting frame 1, and the suction port 5 is installed below the movable frame 3. Connecting devices are connected to both ends of the connecting pipe 4.

The control sleeve 6 is rotatably installed on the outside of the connecting pipe 4, the two limiting sleeves 8 are slidably fitted on the outside of the connecting pipe 4, the spiral groove 9 is opened on the outside of the connecting pipe 4, the connecting rod 10 is fixedly connected to one side of the control sleeve 6, and the sliding rod 11 is fixedly installed on one side of the connecting rod 10. The limiting sleeve 8 and the sliding rod 11 are connected to each other. The rod 11 is slidably connected, the rubber sleeve 12 is detachably installed inside the connecting tube 4, the insertion groove 15 is opened on the outside of the insertion tube 7, the insertion tube 7 is fixedly connected to the top of the dust suction port 5 and one end of the dust collector 2, the insertion rod 13 is fixedly connected to one side of the limiting plate 14, one end of the insertion rod 13 is inserted into the insertion groove 15, the movable block 16 is fixedly set on the inner wall of the limiting sleeve 8, and the movable block 16 slides in the spiral groove 9, a locking mechanism is installed on the outside of the connecting tube 4, the locking mechanism includes a locking sleeve 17, a connecting spring 18, a locking rod 19 and a locking groove 20, the locking sleeve 17 is movably installed on the outside of the connecting tube 4 by threads, multiple locking rods 19 are slidably installed on the side wall of the control sleeve 6, one end of the locking rod 19 is connected to the outer wall of the control sleeve 6 through the connecting spring 18, multiple locking grooves 20 are opened on the outside of the connecting tube 4, and the other end of the locking rod 19 is inserted into the locking groove 20.

[0032] The mounting bracket 1 is movably equipped with a drive assembly 21, and the dust collector 2 is detachably equipped with a dust collection tank 22 below the dust collector 2. The movable frame 3 is installed below the drive assembly 21, and a strong magnet 23 is detachably equipped below the movable frame 3.

[0033] The connecting pipe 4 is a rigid pipe, and a corrugated pipe 24 is provided on the connecting pipe 4. The corrugated pipe 24 is a metal corrugated pipe 24.

[0034] In this embodiment, when the device is needed, the drive assembly 21 is first turned on, causing it to move the lower movable frame 3 and strong magnet 23 laterally. The movable frame 3 stretches the laterally arranged corrugated pipe 24 and compresses the other side of the horizontally arranged corrugated pipe 24. Then, the drive assembly 21 moves the movable frame 3 and strong magnet 23 downwards, causing the movable frame 3 to stretch the suction port 5 and the vertically arranged corrugated pipe 24. Simultaneously, the blower connected to the top of the dust collector 2 is turned on, allowing the suction port 5 to remove dust from the surface of the strong magnet 23, the surface of the suspended object, and... Air is drawn in and then transported to the dust collector 2 through the connecting pipe 4 and the corrugated pipe 24. The dust is then separated and filtered by the dust collector 2 and settled into the dust collection tank 22. The dust collector 2 is a cyclone dust collector. The air is then drawn in by the blower and discharged to the outside. When it drops to a suitable height, the lower surface of the strong magnet 23 contacts the upper surface of the item, and the strong magnet 23 firmly attracts the item. Then, the drive assembly 21 is driven in reverse, so that the drive assembly 21 and the movable frame 3 of the same specification and the strong magnet 23 lift the item. The movable frame 3 will drive the longitudinally arranged corrugated pipe 24 to compress it. Then, the blowers of the two external devices are turned off.

[0035] Please see Figures 3-5 As a further implementation of the overall equipment: a chamfer structure is provided on one end of the plug rod 13 and one side of the inner wall of the plug groove 15.

[0036] Multiple rubber rings 25 are provided on the outside of the insertion tube 7, and multiple grooves 26 are provided on the inner wall of the connecting tube 4, with the rubber rings 25 being inserted into the corresponding grooves 26.

[0037] A push spring 27 is movably provided on the inner side of the limiting plate 14, and the other end of the push spring 27 is connected to the outer wall of the connecting pipe 4.

[0038] The two spiral grooves 9 are designed to face each other.

[0039] Both the end of the locking rod 19 and the inner edge of the locking groove 20 are designed with rounded corners.

[0040] More specifically, when pipe maintenance or replacement is required, firstly, rotate the locking sleeve 17 forward, causing it to move along the threads on the outer wall of the connecting pipe 4. Then, the inner wall of the locking sleeve 17 no longer limits the outer end of the locking rod 19. Next, rotate the control sleeve 6 forward, causing multiple locking rods 19 slidably mounted on the side wall to move. Then, the inner wall of the locking groove 20 presses against one end of the locking rod 19. Due to the rounded corner design at the end of the locking rod 19 and the edge of the inner wall of the locking groove 20, one end of the locking rod 19 slides out of the locking groove 20, and the other end of the locking rod 19 stretches the connecting spring 18. Simultaneously, the control sleeve 6 causes the connecting rod 10 and the sliding rod 11 to rotate forward. Then, the sliding rod 11 causes the two limiting sleeves 8 to rotate in the same direction. Then, the limiting sleeves 8 cause the inner side... Multiple movable blocks 16 slide along corresponding spiral grooves 9. Since the two spiral grooves 9 are designed to face each other, and the two limiting sleeves 8 are slidably connected to the slide rods 11, the movable blocks 16 will drive the two limiting sleeves 8 to slide to the sides. Then, the inner wall of the limiting sleeve 8 no longer limits the outer wall of the limiting plate 14. The push spring 27 then pushes the limiting plate 14 outwards, causing the limiting plate 14 to pull the insertion rod 13 out of the insertion slot 15. The insertion tube 7 is then pulled downwards, disconnecting the dust collection port 5 or dust collector 2 from the connecting tube 4. The connecting tube 4 and corrugated pipe 24 are then replaced as a whole, and reinstalled. The insertion tube 7 is then reinserted into the connecting tube 4, and the insertion tube 7 abuts against... Hold the rubber sleeve 12, then rotate the control sleeve 6 in the opposite direction, causing the control sleeve 6 to rotate and reset the locking rod 19 set on the side wall. This causes the control sleeve 6 to drive the two limiting sleeves 8 to rotate in the opposite direction via the slide rod 11. The two limiting sleeves 8 then drive the corresponding movable blocks 16 to slide in the opposite direction along the corresponding spiral grooves 9. The two limiting sleeves 8 then move in opposite directions along the slide rod 11, gradually moving inwards. The two limiting sleeves 8 gradually press the limiting plate 14 inwards, causing the limiting plate 14 to press against the push spring 27. This causes the limiting plate 14 to drive the insertion rod 13 to gradually insert into the insertion groove 15. Due to the chamfered design of the end of the insertion rod 13 and one side of the inner wall of the insertion groove 15, when the insertion rod 13 is fully inserted into the insertion groove 15, the insertion rod 1... 3 will drive the insertion tube 7 to be pressed inward through the insertion groove 15, so that the insertion tube 7 squeezes the rubber sleeve 12 to ensure the sealing of the pipe connection. At the same time, multiple rubber rings 25 set on the outside of the insertion tube 7 are simultaneously inserted into the corresponding grooves 26, further enhancing the sealing of the pipe connection. Meanwhile, the connecting spring 18 just drives the locking rod 19 to slide and reset into the original locking groove 20. Then, the locking sleeve 17 is rotated in the opposite direction, so that the locking sleeve 17 moves and resets along the thread on the outside of the connecting tube 4. Then, the inner wall of the locking sleeve 17 re-limits the outer end of the locking rod 19, so that the locking rod 19 cannot move. Then, the locking rod 19 and the locking groove 20 cooperate to lock the control sleeve 6, prevent the control sleeve 6 from rotating, and thus ensure the stability of the pipe connection.

[0041] In summary, when using or operating the entire device: First, open the drive assembly 21, causing it to move the lower movable frame 3 and strong magnet 23 laterally. The movable frame 3 will stretch the laterally positioned corrugated pipe 24 and compress the other side's horizontally positioned corrugated pipe 24. Then, the drive assembly 21 will move the movable frame 3 and strong magnet 23 downwards, causing the movable frame 3 to stretch the dust suction port 5 and the vertically positioned corrugated pipe 24. Simultaneously, turn on the blower connected to the top of the dust collector 2, allowing the dust suction port 5 to remove dust from the surface of the strong magnet 23 and the surface of the suspended items. Dust and air are drawn in and then transported to the dust collector 2 through the connecting pipe 4 and the corrugated pipe 24. The dust is then separated and filtered by the dust collector 2 and settled into the dust collection tank 22. The dust collector 2 is a cyclone dust collector. Then, the air is drawn in by the blower and discharged to the outside. When it drops to a suitable height, the lower surface of the strong magnet 23 contacts the upper surface of the item, and the strong magnet 23 firmly attracts the item. Then, the drive assembly 21 is driven in reverse, so that the drive assembly 21 and the movable frame 3 of the same specification and the strong magnet 23 lift the item. The movable frame 3 will drive the longitudinally arranged corrugated pipe 24 to compress it. Then, the blowers of the two external devices are turned off.

[0042] When pipe maintenance or replacement is required, first rotate the locking sleeve 17 clockwise, causing it to move along the threads on the outer wall of the connecting pipe 4. Then, the inner wall of the locking sleeve 17 no longer limits the outer end of the locking rod 19. Next, rotate the control sleeve 6 clockwise. The control sleeve 6 will drive the multiple locking rods 19 slidably mounted on the side wall to move. Then, the inner wall of the locking groove 20 will press against one end of the locking rod 19. Due to the rounded corner design at the end of the locking rod 19 and the edge of the inner wall of the locking groove 20, one end of the locking rod 19 will slide out of the locking groove 20, and the other end of the locking rod 19 will drive the connecting spring 18 to stretch. At the same time, the control sleeve 6 will drive the connecting rod 10 and the sliding rod 11 to rotate clockwise. Then, the sliding rod 11 will drive the two limiting sleeves 8 to rotate in the same direction. Then, the limiting sleeves 8 will drive the inner side of the locking rod 19 to rotate. Multiple movable blocks 16 slide along corresponding spiral grooves 9. Since the two spiral grooves 9 are designed to face each other, and the two limiting sleeves 8 are slidably connected to the slide rods 11, the movable blocks 16 will drive the two limiting sleeves 8 to slide to both sides. Then, the inner wall of the limiting sleeve 8 no longer limits the outer wall of the limiting plate 14. The push spring 27 then pushes the limiting plate 14 outwards, causing the limiting plate 14 to pull the insertion rod 13 out of the insertion slot 15. Then, the insertion tube 7 is pulled downwards, disconnecting the dust suction port 5 or dust collector 2 from the connecting tube 4. Then, the connecting tube 4 and corrugated pipe 24 are replaced as a whole, and then reinstalled in their original positions. The insertion tube 7 is then reinserted into the connecting tube 4, and the insertion tube 7 abuts against the rubber... The rubber sleeve 12 is then rotated in the opposite direction, causing the control sleeve 6 to rotate and reset the locking rod 19 on the side wall. This causes the control sleeve 6 to rotate the two limiting sleeves 8 in the opposite direction via the slide rod 11. The two limiting sleeves 8 then drive the corresponding movable blocks 16 to slide in the opposite direction along the corresponding spiral grooves 9. The two limiting sleeves 8 then move in opposite directions along the slide rod 11, gradually moving inwards. The two limiting sleeves 8 gradually press the limiting plate 14 inwards, causing the limiting plate 14 to press against the push spring 27. This causes the limiting plate 14 to drive the insertion rod 13 to gradually insert into the insertion groove 15. Due to the chamfered design of the end of the insertion rod 13 and one side of the inner wall of the insertion groove 15, when the insertion rod 13 is fully inserted into the insertion groove 15, the insertion rod 13... The insertion slot 15 drives the insertion tube 7 to be pressed inward, causing the insertion tube 7 to squeeze the rubber sleeve 12, ensuring the sealing of the pipe connection. At the same time, multiple rubber rings 25 set on the outside of the insertion tube 7 are simultaneously inserted into the corresponding grooves 26, further enhancing the sealing of the pipe connection. Meanwhile, the connecting spring 18 drives the locking rod 19 to slide back into the original locking groove 20, and then rotates the locking sleeve 17 in the opposite direction, causing the locking sleeve 17 to move back along the thread on the outside of the connecting tube 4. Then, the inner wall of the locking sleeve 17 re-limits the outer end of the locking rod 19, making the locking rod 19 unable to move. Then, the locking rod 19 and the locking groove 20 cooperate to lock the control sleeve 6, preventing the control sleeve 6 from rotating, thereby ensuring the stability of the pipe connection.

For all the fixed connections mentioned above, welding is preferred.
