Description

Technical Field

[0001] The invention relates to the technical field of aeration pipe lifting, in particular to an aeration pipe lifting device. Background Art

[0002] The aeration tube is a new type of aeration facility. Its principle is to use a blower to transport air through a gas pipeline to the aeration device located at the bottom of the pool, and the air is dispersed and escaped in the form of bubbles, dissolving oxygen into the water at the gas-liquid interface. During the processing of the aeration tube, the aeration tube usually needs to be transported at various workstations, and the heights of various workstations are not consistent. Therefore, during the processing, an aeration tube lifting device is usually required to transport the aeration tube to the appropriate workstation height.

[0003] However, in the prior art, the groove size of the lifting frame actually needs to be larger than the size of the aeration pipe to allow better feeding. However, due to the mobility of the aeration pipe in the groove of the lifting frame, the pipes are easily stacked tilted and chaotic during the discharge process, making it impossible to discharge in an orderly manner.

[0004] At the same time, in the prior art, if a simple telescopic device is used for control, the stroke will be short, which is not suitable for aeration pipes of various lengths. Finally, in the prior art, a separate design is required for the stacking structure of the aeration pipes after lifting. During use, the structure is more complicated and the operation process is increased, which greatly affects the efficiency of the equipment. Summary of the invention

[0005] The purpose of the present invention is to solve the problems that the mobility of the aeration pipe in the groove of the lifting frame in the prior art leads to the pipe fittings being easily tilted and stacked in a disorderly manner during the discharge process, and the discharge cannot be orderly; if the prior art adopts a simple telescopic device for control, the stroke is short, which is not conducive to the application of aeration pipes of various lengths; and the prior art requires a separate design for the stacking structure of the aeration pipe after lifting, which has a relatively complex structure and increases the operation process, greatly affecting the efficiency of the equipment. An aeration pipe lifting device is proposed.

[0009] Preferably, the limit assembly includes an end plate, an inspection cover, a fixed rack, a movable rack, a gear and a gear shaft; The multiple end plates are respectively embedded in the inner walls of the grooves on both sides of the lifting frame, and the end plates are slidably connected to the lifting frame, the inner ends of the end plates are fixedly connected to the movable racks, and the movable racks are slidably connected to the inner wall of the lifting frame, the inner side of the movable racks is meshed with gears, the inner sides of the outer walls of the gears are meshed with fixed racks, the two sides of the fixed racks are fixedly connected to the central inner wall of the lifting frame, and the inner wall of the gear is fixedly connected to a gear shaft.

[0010] Preferably, the axis of the end plate is consistent with the center position of the inner walls of the grooves on both sides of the lifting frame.

[0011] Preferably, a hopper bracket is fixedly connected to the lower front end of the side bracket, and a feed hopper is fixedly connected to the upper inner wall of the hopper bracket.

[0012] Preferably, the power assembly includes a turntable, a slot plate, a round rod, a sliding rod, a sliding sleeve and a driving motor; The driving motor is fixedly installed on the rear side of the central partition of the lifting frame, the output shaft of the driving motor is fixedly connected to a turntable, and round rods are fixedly connected to the upper right and lower left of the center of the turntable, the outer wall of the round rod is slidably connected to a groove plate, the inner ends of the groove plates are rotatably connected to the gear shaft, the outer sides of the outer walls of the groove plates and the movable rack are fixedly connected to sliding sleeves, the inner walls of the sliding sleeves are slidably connected to sliding rods, and the ends of both sides of the sliding rods are fixedly connected to the central inner wall of the lifting frame.

Through the cooperation among the slot plate, the gear, the movable gear, the fixed rack and the end plate, the slot plate drives the gear to change position synchronously during the process of the slot plate moving outward, and because the inner and outer sides of the gear are respectively meshed with the fixed rack and the movable rack, the gear is first blocked by the fixed rack and rotates when moving outward, and then drives the movable rack to move a distance based on the moving distance of the gear, so that the end plate moves at a multiple distance, so that the lateral telescopic range of the end plate is larger, and the problem of the prior art that if a simple telescopic device is used for control, the stroke is short and it is not suitable for aeration pipes of various lengths and sizes is effectively avoided; Through the coordination between the lifting frame and the chain plate type elevator, the lifting frame is designed as a unit block structure in this case, so that the specific structure, installation process and control method of each lifting frame are consistent, which greatly reduces the difficulty of equipment maintenance and makes the lifting frames evenly distributed on the outer wall of the chain plate of the chain plate type elevator. Once damaged, only the lifting frames at the corresponding positions need to be removed and reinstalled as a group, which effectively avoids the problem that the prior art needs to separately design the stacking structure of the aeration pipe after lifting, which has a more complicated structure and increases the operation process, greatly affecting the efficiency of equipment use.

The movable racks 404 can drive the end plates 401 to slide in the lifting frame 303. The inner side of the movable racks 404 is meshed with gears 405. The inspection cover 402 can be opened and closed from the front of the lifting frame 303. The side center is taken out in order to observe the operation of the internal gear rack.

The axis of the end plate 401 is consistent with the center position of the inner wall of the groove on both sides of the lifting frame 303.

[0020] See attached Figure 1-Figure 8 : In this embodiment, the power assembly 5 includes a turntable 501, a slot plate 502, a round rod 503, a sliding rod 504, a sliding sleeve 505 and a driving motor 506; The driving motor 506 is fixedly installed on the rear side of the central partition of the lifting frame 303. The model of the driving motor 506 can be determined according to the specific usage. The driving motor 506 is a servo motor with its own power supply and remote control, and does not require wiring control. The output shaft of the driving motor 506 is fixedly connected to the turntable 501. Round rods 503 are fixedly connected to the upper right and lower left of the center of the turntable 501. The outer wall of the round rod 503 is slidably connected to the slot plate 502. The rotation of the turntable 501 can drive the slot plates 502 on both sides to move synchronously through the round rod 503. The slot plates 502 on both sides can move synchronously inward or outward. The inner ends of the slot plates 502 are rotatably connected to the gear shaft 406. The outer sides of the outer walls of the slot plates 502 and the movable rack 404 are fixedly connected to the sliding sleeves 505. The inner walls of the sliding sleeves 505 are slidably connected to the sliding rods 504. The ends of the sliding rods 504 on both sides are fixedly connected to the central inner wall of the lifting frame 303.

[0021] By the cooperation among the driving motor 506, the turntable 501, the round rod 503, the lifting frame 303, the slot plate 502, the end plate 401 and the discharge hopper 6, the driving motor 506 can be started to control the rotation of the turntable 501. At the same time, the turntable 501 drives the slot plates 502 on both sides to move synchronously through the round rod 503, and then the slot plates 502 can drive the end plates 401 on both sides to move outward, so that the end plates 401 are against the inner ends of the aeration pipes on both sides, so as to achieve the position restriction of the aeration pipes in the grooves of the lifting frame 303 after taking the materials. Before discharging, the driving motor 506 is controlled to reverse, and the end plates 401 are released from the aeration pipes, so that the aeration pipes can be discharged in an orderly manner through the discharge hopper 6 smoothly, effectively avoiding the problem that the mobility of the aeration pipes in the grooves of the lifting frame 303 in the prior art leads to the inclined stacking and confusion of the pipes during the discharging process, and the material cannot be discharged in an orderly manner. Through the cooperation among the slot plate 502, the gear 405, the movable rack 404, the fixed rack 403 and the end plate 401, when the slot plate 502 moves outward, the slot plate 502 drives the gear 405 to change its position synchronously, and because the inner and outer sides of the gear 405 are respectively meshed with the fixed rack 403 and the movable rack 404, the gear 405 is first blocked by the fixed rack 403 and rotates when moving outward, and then drives the movable rack 404 to move a distance based on the moving distance of the gear 405, so that the end plate 401 moves a multiple of the distance, so that the lateral telescopic range of the end plate 401 is larger, which effectively avoids the problem that if the prior art adopts a simple telescopic device control, the stroke is short, which is not conducive to the application of aeration pipes of various lengths and sizes; Through the coordination between the lifting frame 303 and the chain plate type elevator 301, the lifting frame 303 is designed as a unit block structure in this case, so that the specific structure, installation process and control method of each lifting frame 303 are consistent, which greatly reduces the difficulty of equipment maintenance, and makes the lifting frames 303 evenly distributed on the outer wall of the chain plate of the chain plate type elevator 301. Once damaged, only one set of lifting frames 303 at the corresponding position needs to be removed and reinstalled, which effectively avoids the problem that the prior art needs to separately design a stacking structure of the aeration pipe after lifting, which has a more complicated structure and increases the operation process, greatly affecting the efficiency of equipment use.

[0022] Working principle: When the aeration tube lifting device is needed, the user first places the entire device at the corresponding position, so that the feed hopper 9 is aligned with the collecting and conveying part of the aeration tube, and the discharge hopper 6 is aligned with the discharging and conveying part of the aeration tube. Before use, the lifting motor 307 is started first, so that the output shaft of the lifting motor 307 drives the chain plate type elevator 301 to rotate through the transmission structure 306, and then the collection and conveying part of the aeration tube is controlled to discharge, so that the aeration tube enters the interior of the feed hopper 9. At the same time, as the chain plate of the chain plate type elevator 301 rotates continuously, the lifting frame 303 can be driven to rotate, and the grooves on both sides of the lifting frame 303 can be embedded with an aeration tube in the process of continuously aligning with the feed hopper 9. As the chain plate of the chain plate type elevator 301 rotates continuously, the aeration tube is continuously transported upward and finally discharged from the discharge hopper 6, thereby realizing the lifting process of the aeration tube.

[0023] However, compared with the prior art, the groove size of the lifting frame 303 actually needs to be larger than the size of the aeration pipe in order to better feed the material. However, due to the mobility of the aeration pipe in the groove of the lifting frame 303, the pipes are prone to tilt and stack in a disorderly manner during the discharge process, and the material cannot be discharged in an orderly manner. Therefore, the power component 5 is designed in this case, so that the driving motor 506 can start to control the rotation of the turntable 501. At the same time, the turntable 501 drives the groove plates 502 on both sides to move synchronously through the round rod 503, so that the groove plates 50 2 can drive the end plates 401 on both sides to move outward, so that the end plates 401 are against the inner ends of the aeration pipes on both sides, so as to realize the position restriction of the aeration pipes in the groove of the lifting frame 303 after taking the material. Before discharging, the driving motor 506 is controlled to reverse, and the tight contact between the end plates 401 and the aeration pipes is released, so that the aeration pipes can be discharged smoothly through the discharge hopper 6 in an orderly manner, effectively avoiding the problem that the mobility of the aeration pipes in the groove of the lifting frame 303 in the prior art leads to the inclined stacking and confusion of the pipes during the discharging process, and the material cannot be discharged in an orderly manner.

[0024] Moreover, compared with the prior art, if a simple telescopic device is used for control, the stroke is shorter, which is not suitable for aeration pipes of various lengths and sizes. Therefore, the present invention designs a limit assembly 4, so that in the process of the slot plate 502 moving outward, the slot plate 502 drives the gear 405 to change its position synchronously, and because the inner and outer sides of the gear 405 are respectively meshed with the fixed rack 403 and the movable rack 404, the gear 405 is first blocked by the fixed rack 403 and rotates when moving outward, and then drives the movable rack 404 to move a distance based on the moving distance of the gear 405, so that the end plate 401 moves an exponential distance, so that the lateral telescopic range of the end plate 401 is larger, which effectively avoids the problem that the prior art uses a simple telescopic device for control, which results in a shorter stroke and is not suitable for aeration pipes of various lengths and sizes.

[0025] Finally, compared with the prior art that requires a separate design for the stacking structure of the aeration pipe after lifting, its structure is more complicated and the operation process is increased during use, which greatly affects the efficiency of equipment use. Therefore, in this case, the lifting frame 303 is designed as a unit block structure, so that the specific structure, installation process and control method of each lifting frame 303 are consistent, which greatly reduces the difficulty of equipment maintenance, and makes the lifting frames 303 evenly distributed on the outer wall of the chain plate of the chain plate elevator 301. Once damaged, only the lifting frames 303 at the corresponding position need to be removed and reinstalled. This effectively avoids the problem that the prior art needs to separately design the stacking structure of the aeration pipe after lifting, which has a more complicated structure and increases the operation process, greatly affecting the efficiency of equipment use.

[0026] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
