[0002] An air compressor is a device that compresses gas into high-pressure gas. It is used in cigarette machines, packaging machines, textile processing equipment, logistics equipment, dust removal equipment, etc., to provide power air for the pneumatic components and some process parts of these devices. Since gas generates heat during compression, the compressed air needs to be cooled. There are many cooling methods for air compressors, among which an aftercooler is a commonly used cooling device. It primarily reduces the temperature of the high-temperature compressed air discharged from the air compressor through a heat exchange process. By condensing water vapor and oil mist in the high-temperature air, it ensures the compressed air temperature is suitable and removes impurities, thereby guaranteeing the stable operation of the air compressor and the quality of the compressed air. Air compressors need to be disassembled periodically for maintenance and upkeep to ensure the cooling effect.

[0003] The air compressor aftercooler is installed at the bottom of the air compressor body. It is heavy and has limited installation space. Currently, maintenance personnel use rope hoisting to disassemble and install it, which is time-consuming, labor-intensive, and poses certain safety hazards.

[0004] In view of the above reasons, this utility model proposes a disassembly and transfer device for an air compressor aftercooler to solve the above technical problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-4 As shown, this utility model provides a disassembly and transfer device for an air compressor aftercooler, including: a column 1, a base 2 fixed to the bottom end of the column 1, multiple rollers 3 installed on the bottom of the base 2, a lifting platform 4 provided on the base 2, a boom 5 extending to one side provided at the top end of the column 1, a lifting mechanism provided on the boom 5, the lifting mechanism can extend into the air compressor housing along with the boom 5, lift the disassembled aftercooler, retract it and place it on the raised lifting platform 4, and then be transferred by maintenance personnel to the maintenance station for maintenance.

[0030] Specifically, the lifting mechanism includes an electric hoist 6, a lifting rope 7, a pulley 8, and a hook 9. The electric hoist 6 can be a mini electric hoist selected according to the lifting weight of the aftercooler. The electric hoist 6 is set at the beginning of the boom 5. The pulley 8 is rotatably installed at the end of the boom 5. The lifting rope 7 is a steel wire rope, which is wound around the outer circumference of the drum of the electric hoist 6. One end of the lifting rope 7 extends along the boom 5 and passes over the top of the pulley 8 at its end, and is fixedly connected to the hook 9. The aftercooler can be lifted out of the air compressor box through the hook 9 and the strap, and placed on the raised lifting platform 4 and fixed. Then, the lifting platform 4 is lowered to the lowest point, and the whole device is moved to the corresponding maintenance station for maintenance.

[0031] In this embodiment, there are 4 rollers 3, including 2 omnidirectional wheels installed on the front side of the base 2 and 2 directional wheels installed on the rear side of the base 2. The column 1 is perpendicularly fixed to the front side of the base 2. The base 2 is welded from rectangular steel pipes and steel plates. The column 1 is cylindrical and its bottom end is detachably connected to the base 2 through mounting base 101 and fastening bolts.

[0032] In this embodiment, the lifting platform 4 is a scissor lift platform, which includes multiple sets of scissor lifts 401 connected in sequence and a supporting platform 402 mounted on top of them. The scissor lift platform is driven to lift and lower by a lifting mechanism 403. The lifting mechanism 403 is preferably a horizontal hydraulic jack. One end of the lifting mechanism 403 is rotatably connected to the scissor lifts 401, and the other end of the lifting mechanism 403 is rotatably connected to the base 2. The other end of the lifting mechanism 403 is provided with an operating handle 404, which can be used to lift the lifting mechanism 403. Since one end of the lifting mechanism 403 is rotatably connected to the scissor lifts 401, when the lifting mechanism 403 extends, it can drive the scissor lifts 401 to rotate and rise, thereby raising the supporting platform 402 to support the lifted aftercooler.

[0033] The lifting platform 4 has a conveyor roller platform 405 on its support platform 402 surface. The support platform 402 surface is equipped with rotatable limiting rollers 16. The conveyor roller platform 405 has grooves on both sides that mate with the limiting rollers 16, allowing it to extend and retract relative to the support platform 402. Multiple parallel rollers are mounted on the conveyor roller platform 405. The aftercooler 405 can move along the conveyor roller platform 405 to the front of the support platform 402. An aftercooler clamp can be installed on the front of the support platform 402, typically using a ring-shaped positioning fixture and clamping mechanisms symmetrically arranged around its periphery for positioning and clamping. After the aftercooler is fixed, the lifting platform 4 returns to its initial height under the action of the operating handle 404. The base 2 has an upwardly extending U-shaped handle 10 on its front side, allowing for easy movement of the device and aftercooler as a whole, thus transferring the aftercooler to the maintenance station.

[0034] In this embodiment, the boom 5 includes a crossbeam 501 and a sliding beam 502. One end of the crossbeam 501 is hollow, and the sliding beam 502 is slidably connected to the crossbeam 501. The pulley 8 is located at the end of the sliding beam 502. The beginning end of the crossbeam 501 is bent at a right angle. Under normal circumstances, the boom 5 extends horizontally. By adjusting the length of the boom 5, it can be extended into the air compressor housing, making it convenient to use the hook 9 to lift out the aftercooler. Then the boom 5 retracts, and the electric hoist 6 drives the lifting rope 7 and the hook 9 to descend, placing the aftercooler on the conveyor roller platform 405, and then moving it to the front of the bearing platform 402 for positioning and clamping.

[0035] In this embodiment, the column 1 is cylindrical, with a rotating member 11 at its top. The rotating member 11 is rotatably connected to the outer periphery of the top of the column 1 via a bearing 12. A symmetrically arranged positioning plate 13 is provided on the top of the rotating member 11. The right-angled bottom end of the crossbeam 501 is rotatably connected to the top of the positioning plate 13. Multiple limiting grooves 1301 are symmetrically arranged on the outer side of the positioning plate 13. The limiting grooves 1301 are continuously arranged in a wave-like or toothed shape on the outer edge of the positioning plate 13. A rotating shaft 14 is provided in the limiting groove 1301. The two ends of the rotating shaft 14 are rotatably connected to the crossbeam 501 via support rods 15. A rib plate is provided at the bottom of the crossbeam 501 and rotatably connected to the support rods 15. By adjusting the rotating shaft 14 in conjunction with different limiting grooves 1301, the tilt angle of the crossbeam 501 relative to the horizontal direction can be adjusted.

[0036] In this embodiment, a pin hole 503 is provided on the surface of the crossbeam 501, and a limiting pin is installed in the pin hole 503. The limiting pin is used to limit the extension length of the sliding beam 502 relative to the crossbeam 501. A locking rod 17 is installed on the outer periphery of the rotating part 11 and is threadedly connected to it. The top of the column 1 is provided with a boss with a diameter smaller than its own. The locking rod 17 can cooperate with the top boss of the column 1 to lock it. With the above structure, the rotation angle of the boom 5 relative to the column 1, the tilt angle relative to the horizontal plane, and the overall length can be adjusted, so that the hook 9 can be inserted into the air compressor housing to respond to the position, thereby lifting the disassembled aftercooler.

[0037] The working process of this utility model device is as follows:

[0038] 1. Push the device to the position of the air compressor aftercooler, adjust the boom 5 to extend into the air compressor housing, and lift the aftercooler out of the air compressor housing using the hook 9. Retract the boom 5 and place the aftercooler on the lifting platform 4. Move the aftercooler along the conveyor roller platform 405 to the front of the bearing platform 402 and fix the aftercooler with clamps. Apply a force to the aftercooler filter element using the set screw, and the aftercooler can be quickly disassembled for maintenance, which is safe and efficient.

[0039] 2. Place the assembled aftercooler on the lifting platform 4. Use the device's walking, lifting, turning and hoisting functions to quickly transport the aftercooler into the air compressor housing for installation, thus completing the maintenance work of the air compressor aftercooler.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
