[0027] The lifting device of the filter element can greatly simplify the disassembly and assembly process of the filter element, improve the efficiency of replacing the filter element, and reduce the operation cost.

[0028] Figure 1is a structural schematic view of a lifting device for a filter cartridge in an embodiment of the present application. As shown in Figure 1 The lifting device 100 for the filter cartridge according to the embodiment of the present application comprises a support assembly 10, a sliding block 20, a first driving assembly 30, a lifting part 40 and a second driving assembly 50. The support assembly 10 comprises a stand 11 and a lifting arm 12. The stand 11 extends along a first direction X, the lifting arm 12 extends along a second direction Y, one end of the lifting arm 12 is connected with the stand 11, and the first direction X and the second direction Y intersect. The sliding block 20 is installed on the lifting arm 12. The first driving assembly 30 is installed on the support assembly 10, the sliding block 20 is connected with the first driving assembly 30, and the first driving assembly 30 drives the sliding block 20 to move along the second direction Y. The second driving assembly 50 is installed on the sliding block 20, the second driving assembly 50 is connected with the lifting part 40, and the second driving assembly 50 drives the lifting part 40 to move along the first direction X.

[0029] It should be noted that the first driving assembly 30 can be an electric servo assembly or a fixed pulley assembly. When the first driving assembly 30 is an electric servo assembly, the electric servo assembly is installed on the lifting arm 12, and the electric servo assembly is connected with the sliding block 20 and can drive the sliding block 20 to move along the second direction Y relative to the lifting arm 12. When the first driving assembly 30 is a fixed pulley assembly, the fixed pulley assembly drives the sliding block 20 to move along the second direction Y relative to the lifting arm 12. Of course, in other optional embodiments, the first driving assembly 30 can also be a motor and screw assembly, an electric push rod or a pneumatic cylinder, as long as it can drive the sliding block 20 to move along the second direction Y relative to the lifting arm 12.

[0030] The lifting part 40 can be a hook, a clamping assembly or a suction assembly, etc. The lifting part 40 is mainly used for fixing and connecting the filter cartridge, so as to lift the filter cartridge.

[0031] According to the lifting device 100 for the filter cartridge according to the embodiment of the present application, when the filter cartridge needs to be replaced, the operator first drives the sliding block 20 to move along the lifting arm 12 to above the position of the filter cartridge by the first driving assembly 30, then drives the lifting part 40 to descend along the first direction X by the second driving assembly 50, so that the lifting part 40 contacts and firmly connects with the filter cartridge, then drives the lifting part 40 to ascend by the second driving assembly 50, so as to lift the filter cartridge out of the filter, the operator moves the sliding block 20 and the lifting part 40 carrying the filter cartridge to a designated placement position by the first driving assembly 30, and finally lowers the filter cartridge to the designated position by the second driving assembly 50. In the whole process, the operator does not need to use large equipment such as a crane, and can easily complete the replacement of the filter cartridge, simplifying the disassembly and assembly process, improving the efficiency of replacing the filter cartridge, and reducing the operation cost.

[0032] As shown in Figure 1As shown, in some embodiments, the first drive assembly 30 includes a winding reel 31, a first fixed pulley 32, and a traction rope 33. The winding reel 31 is located at the end of the column 11 away from the boom 12. The first fixed pulley 32 is located at the end of the boom 12 away from the column 11. The traction rope 33 is wound around the winding reel 31. The traction rope 33 includes a first end and a second end opposite to each other. The first end passes over the first fixed pulley 32 and is connected to the slider 20. The second end is directly connected to the slider 20.

[0033] The first fixed pulley 32 is located at the end of the boom 12 away from the column 11. The first end of the traction rope 33 passes around the first fixed pulley 32 and is connected to the slider 20. The first fixed pulley 32 is mainly used to change the tension and traction direction of the first end of the traction rope 33 on the slider 20, so that the first end and the second end of the traction rope 33 can drive the slider 20 to move back and forth relative to the boom 12 in the second direction Y, so as to realize the translation of the filter element.

[0034] In this embodiment, the drive wheel 31 rotates clockwise or counterclockwise to release or retract the traction rope 33. When the drive wheel 31 rotates clockwise, the first end of the traction rope 33 is retracted, the second end of the traction rope 33 is released, and the first end of the traction rope 33 pulls and slides relative to the boom 12 along the second direction Y, moving away from the column 11. When the drive wheel 31 rotates counterclockwise, the first end of the traction rope 33 is released, the second end of the traction rope 33 is retracted, and the second end of the traction rope 33 pulls and slides relative to the boom 12 along the second direction Y, moving closer to the column 11. The first drive assembly 30, through the coordinated action of the drive wheel 31, the fixed pulley, and the traction rope 33, achieves smooth reciprocating motion of the slider 20 relative to the boom 12 along the second direction Y. In some optional embodiments, the drive wheel 31 is also provided with a bidirectional limiting ratchet, which allows the drive wheel 31 to be limited after the slider 20 has moved to a fixed position by rotating, preventing the slide rail trolley from moving.

[0035] like Figure 1 As shown, in some embodiments, the first drive assembly 30 further includes a second fixed pulley 34. The second fixed pulley 34 is disposed at one end of the column 11 near the boom 12. A first end is sequentially wound around the second fixed pulley 34 and the first fixed pulley 32, and the first end is connected to the slider 20.

[0036] In this embodiment, the second fixed pulley 34 optimizes the path of the traction rope 33, ensuring that the first end of the traction rope 33 can smoothly transition from the winding wheel 31 to the first fixed pulley 32 on the boom 12 without excessive friction, wear, or jamming due to excessive angle or unreasonable path. Furthermore, during the movement of the slider 20, the traction rope 33 is subjected to tension from the slider 20. The presence of the second fixed pulley 34 helps to distribute and balance these tensions, ensuring that the traction rope 33 is evenly stressed when passing over the pulley, reducing the risk of wear or breakage due to uneven stress. Simultaneously, the second fixed pulley 34 provides tension to the first end of the traction rope 33, ensuring that the traction rope 33 maintains a stable path and tension during release or retrieval, reducing the risk of safety accidents caused by loss of control or breakage of the traction rope 33, and making the structure of the first drive assembly 30 more compact and efficient.

[0037] like Figure 1 As shown, in some embodiments, the first drive assembly 30 further includes a third fixed pulley 35. The third fixed pulley is disposed on the column 11, and the third fixed pulley 35 is disposed between the second fixed pulley 34 and the winding wheel 31. The second end is wound around the third fixed pulley 35, and the second end is connected to the slider 20.

[0038] In this embodiment, the third fixed pulley 35 serves the same function as the second fixed pulley 34. By adding the third fixed pulley 35, the path of the second end of the traction rope 33 is further optimized. This ensures that the second end of the traction rope 33 can smoothly transition from the winding wheel 31 to the slider 20 on the boom 12 without excessive friction, wear, or jamming due to excessive angle or unreasonable path. It also further disperses the tension on the traction rope 33, ensuring that the traction rope 33 is evenly stressed and reducing the risk of wear and breakage. The third fixed pulley 35 provides additional tension to the second end of the traction rope 33. This helps maintain a stable path and tension of the traction rope 33 during release or retrieval, reducing the risk of safety accidents caused by loss of control or slack in the traction rope 33.

[0039] like Figure 1 As shown, in some embodiments, the second drive assembly 50 is at least one of a manual chain hoist, an electric hoist, and a pulley lifting assembly.

[0040] In the present embodiment, the second driving assembly 50 is mounted on the sliding block 20 and connected with the lifting part 40 to drive the lifting part 40 to lift along the first direction X to drive the filter core of the filter to lift along the first direction X. When the first driving assembly 30 is a hand chain block, the lifting part 40 is connected with the chain of the hand chain block, and the lifting of the lifting part 40 is realized by manually pulling the chain, which is flexible and convenient to use. Similarly, when the second driving assembly 50 is an electric chain block, the lifting of the lifting part 40 is realized by driving the winding drum of the electric chain block to wind or unwind the steel wire rope or chain, which is fast in lifting speed, high in efficiency and easy to operate. When the second driving assembly 50 is a pulley lifting assembly, the fixed pulley is fixedly connected to the sliding block 20, and the traction rope 33 or chain changes direction through the fixed pulley to drive the lifting of the lifting part 40.

[0041] As shown in Figure 1 In some embodiments, the support assembly 10 further includes a first telescopic member 14. The boom 12 is hinged to the stand 11. The first telescopic member 14 is arranged between the boom 12 and the stand 11. The first telescopic member 14 drives the boom 12 to rotate relative to the stand 11 along the hinge axis of the boom 12. The hinge axis of the boom 12 intersects the first direction X.

[0042] In the present embodiment, the rotation angle of the boom 12 relative to the stand 11 is adjusted through the telescoping of the first telescopic member 14, so that the boom 12 can adapt to different working scenarios and requirements, improving the flexibility and applicability of the device. At the same time, when the device is not in use, the boom 12 can be folded, making the device more convenient during storage and transportation, saving the occupied space of the device, and the folded boom 12 makes the entire device more compact, facilitating the movement and transportation of the operator.

[0043] As shown in Figure 1 In some embodiments, the support assembly 10 further includes a base 13 and a second telescopic member 15. The stand 11 is hinged to the base 13. The second telescopic member 15 is arranged between the stand 11 and the base 13. The second telescopic member 15 drives the stand 11 to rotate relative to the base 13 about the hinge axis of the stand 11. The hinge axis of the stand 11 intersects the first direction X.

[0044] In the present embodiment, the rotation angle of the stand 11 relative to the base 13 is adjusted through the telescoping of the second telescopic member 15, so that the stand 11 can adapt to different working scenarios and requirements, improving the flexibility and applicability of the device. When the device is not in use, the stand 11 can be folded to reduce the occupied space of the device, facilitating the movement and transportation of the operator.

[0045] In some optional embodiments, the first telescopic member 14 and the second telescopic member 15 can be electric push rods, hydraulic telescopic cylinders or electric telescopic cylinders, etc.

[0046] AsFigure 1 As shown, in some embodiments, the support assembly 10 further includes a hydraulic oil tank 16. Both the first telescopic member 14 and the second telescopic member 15 are hydraulic cylinders. The oil inlet of the first telescopic member 14 and the oil inlet of the second telescopic member 15 are connected to the hydraulic oil tank 16 via two-position three-way ball valves. The oil outlet of the first telescopic member 14 and the oil outlet of the second telescopic member 15 are connected to the hydraulic oil tank 16 via a three-way valve.

[0047] In this embodiment, by switching the two-position three-way ball valve to the corresponding position, the hydraulic oil tank 16 extends through the oil inlet to either the first telescopic member 14 or the second telescopic member 15. When the first telescopic member 14 or the second telescopic member 15 needs to retract, by controlling the switching direction of the two-position three-way ball valve, the oil outlets of the first telescopic member 14 and the second telescopic member 15 can be connected to the oil tank together, ensuring smooth return of hydraulic oil.

[0048] like Figure 1 As shown, in some embodiments, at least one of the slider 20 or the boom 12 is provided with rollers, and the slider 20 and the boom 12 roll together, reducing the frictional resistance between the slider 20 and the boom 12, reducing motor power, reducing energy consumption, and improving the operating efficiency of the system. This also improves the smoothness and stability of the slider 20's movement.

[0049] like Figure 1 As shown, in some embodiments, the support assembly 10 further includes a base 13 and a plurality of wheels 17. The column 11 is connected to the base 13, and the wheels 17 are mounted on the base 13. And / or the base 13 further includes a plurality of legs 18, which are rotatably connected to the base 13, and the rotation axis of the legs 18 intersects the first direction X.

[0050] In this embodiment, the base 13 is equipped with multiple wheels 17, allowing the filter element lifting device 100 to move freely for easy transport. Multiple support legs 18, rotatably connected to the base 13, can be rotated to lower and secure the support legs during use. When the device needs to be moved, rotating the shaft raises the support legs, releasing the fixation. This allows the filter element lifting device 100 to adapt to uneven ground or inclined working environments, ensuring its stability and support capacity.

[0051] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention.
