[0045] The first aspect of the application discloses a linkage elevator structure, which is in transmission connection with the transmission shaft 4 and the elevator structure 3, so that the rotation of the transmission shaft 4 can drive the elevator structure 3 to move relative to the elevator shell 1, and the elevator structure 3 can complete the lifting action in a short time to achieve the purpose of fixing the filter cartridge. The transmission structure 2 is connected with the transmission shaft 4, which can drive the transmission structure 2 to make the transmission shaft 4 rotate synchronously to realize the installation action of the elevator structure 3 on the filter cartridge. Moreover, the ascending or descending state of the elevator structure 3 can be switched by changing the rotation direction of the transmission structure 2. This design makes the installation of the filter cartridge more labor-saving, effectively reduces the labor intensity of workers, and has higher installation efficiency. The elevator shell 1 provides stable support for the elevator structure 3, ensures that the elevator structure 3 does not deviate or shake during lifting, and improves the safety and success rate of installation.

[0046] As shown, Figures 1-3 In addition to the features of the above-mentioned embodiment, the embodiment further limits that: the outer side of the elevator structure 3 forms a first thread, the outer side of the transmission shaft 4 forms a second thread, and the first thread is matched with the second thread. Through the matching of the first thread and the second thread, the elevator structure 3 can rotate relative to the elevator shell 1, so that the elevator structure 3 realizes the ascending or descending action. This design provides precise linear motion control, so that the elevator structure 3 can move at a stable speed, and ensures the controllability of the accuracy of the filter cartridge installation.

[0047] As shown, Figures 1-3As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further limited in that: the number of the transmission structures 2 is multiple, the multiple transmission structures 2 are all connected with the transmission shaft 4, and the multiple transmission structures 2 can all rotate relative to the elevator shell 1. By making the multiple transmission structures 2 all rotate relative to the elevator shell 1, the jacking action of the multiple lifting structures 3 can be simultaneously realized, so that multiple filter cartridges can be simultaneously installed, and the installation efficiency of the filter cartridges is higher.

[0048] As shown in the drawings, Figures 1-3 As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further limited in that: the number of the second through holes 101 is two, the two second through holes 101 are oppositely arranged, and the two ends of the transmission shaft 4 are respectively arranged in the two second through holes 101 and are respectively connected with the transmission structure 2.

[0049] As shown in the drawings, Figure 4 As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further limited in that: the elevator shell 1 comprises a first shell 11 and a second shell 12, the second shell 12 is provided with a second accommodating cavity, the first shell 11 is arranged on the second shell 12, the first shell 11 is provided with the first accommodating cavity, the first shell 11 is provided with the first through hole and the second through hole 101, the first shell 11 and / or the second shell 12 is provided with a third through hole, the third through hole is respectively communicated with the first accommodating cavity and the second accommodating cavity, the third through hole is oppositely arranged with the first through hole, and the lifting structure 3 can extend into the second accommodating cavity after sequentially passing through the first through hole, the accommodating cavity and the third through hole. By making the lifting structure 3 extend into the second accommodating cavity after sequentially passing through the first through hole, the accommodating cavity and the third through hole, the space for the lifting structure 3 to move up and down is larger, and longer lifting structures 3 can be adapted, so that filter cartridges at higher positions can be fixed, and the flexibility and applicability of the equipment are improved.

The lifting plate 32 is disposed on the rotating rod 31 and located at the end of the rotating rod 31. The lifting plate 32 is used to fix the filter cartridge. The up-and-down movement is achieved by the rotating rod 31 rotating relative to the lifting housing 1, thereby making the lifting action of the lifting structure 3 controllable. This avoids the lifting plate 32 applying excessive force to the filter cartridge, which could damage the filter cartridge, thus improving the safety and reliability of the equipment.

[0051] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further includes a first sealing member 5, which is disposed on the elevator housing 1. The first sealing member 5 has a fourth through hole 501, which is disposed opposite to the first through hole. The lifting structure 3 passes through the fourth through hole 501 and the first through hole, and extends into the first receiving cavity after passing through the fourth through hole 501 and the first through hole in sequence. The provision of the first sealing member 5 increases the sealing between the lifting structure 3 and the elevator housing 1, preventing external dust and impurities from entering the first receiving cavity.

Furthermore, the threads of the transmission shaft 4 and the lifting structure 3 have self-locking characteristics, providing smooth and controllable lifting movements, reducing vibration and impact, and improving the stability of the equipment.

[0053] like Figures 1-3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of transmission structures 2 is multiple, and the multiple transmission structures 2 are respectively a first transmission component 21 and a second transmission component 22; the number of transmission shafts 4 is multiple, the first transmission component 21 is connected to one of the multiple transmission shafts 4, and the first transmission component 21 can drive the transmission shaft 4 to rotate relative to the lifting housing 1; adjacent two transmission shafts 4 are connected through the second transmission component 22.

This linkage control method for fixing the filter cartridge is simpler and simplifies the operation process. Moreover, operating multiple lifting structures 3 simultaneously through a single control point greatly shortens the time for filter cartridge installation or disassembly, improving work efficiency.

[0054] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first transmission assembly 21 includes a first coupling 211, a drive shaft 212, and a fixed structure 213.

The connecting member can pass through the first mounting hole 202 and the second mounting hole 203 in sequence and then connect to an external component. The sleeve 2131 isolates the drive shaft 212 and the fixing member 2132, preventing direct contact between them and greatly reducing wear caused by friction. Connecting components, such as bolts, pass sequentially through the first mounting hole 202 and the second mounting hole 203 to connect with external components, such as the dust removal device, ensuring a secure connection of the entire linkage lifting structure and preventing loosening and detachment.
