[0002] The traditional assembly and disassembly tool for cantilever drum fan-shaped plates is a modular structure, consisting of components such as guide chains, slings, lifting rings, shackles, and hydraulic jacks.

[0003] When inspecting the cantilever drum's sector plates, multiple sets of guide chains are needed to tension the slings and support the sector plates, and one set of guide chains is needed to support the shaft head. The bottom sector plate is a load-bearing component; if the sling tension is insufficient during disassembly, the sector plate can easily slip, causing equipment damage. Furthermore, when inspecting one sector plate, the other three are only supported by the guide chains and slings without locking or securing them, posing a safety hazard. In addition, disassembling a sector plate requires two people to tighten the guide chains to hold the bottom sector plate, and two people to disassemble the top sector plate for inspection, consuming excessive manpower.

[0004] Therefore, there is an urgent need to propose an auxiliary device for disassembling and assembling cantilever drum fan-shaped plates. Utility Model Content

In the prior art, the reducer is connected to the drum. The fixing component 1 can be fixedly installed on the shaft connected to the reducer on the drum. The fixing component 1 includes at least two arc-shaped plates 11 and a mounting part 12 disposed between the ends of two adjacent arc-shaped plates 11. In this embodiment, two arc-shaped plates 11 are used, and the arc-shaped plates 11 are fixedly installed on the drum through the mounting part 12.

[0036] Reference Figure 1 , Figure 2 and Figure 9 The device also includes a support assembly 2. The number of support assemblies 2 is the same as the number of sector plates. In this embodiment, there are four sets of support assemblies 2, which include support members 21 arranged on the arc plate 11. The support members 21 are detachably installed on the arc plate 11. A snap-fit ​​member 22 is provided at one end of the support member 21 away from the fixing assembly 1. The snap-fit ​​member 22 can be inserted into the groove on the outside of the cantilever drum sector plate. The position of the snap-fit ​​member 22 corresponds one-to-one with the position of the groove of the sector plate.

[0037] Reference Figure 1 , Figure 2 and Figure 9Specifically, during the actual disassembly of the sector plates, the drum core is first expanded, and the shaft head is locked with a chain hoist and sling. The shaft head is slightly lifted to apply force, and then the shaft head fixing bolts are removed. A hydraulic jack is used to detach the shaft head from the sector plate. Then, the two arc plates 11 are fixedly installed onto the drum using the mounting part 12. The support member 21 is then fixedly installed onto the arc plate 11. Except for the snap-fit ​​member 22 corresponding to the top sector plate, the other snap-fit ​​members 22 are snapped into the corresponding grooves on the three sector plates. The sector plates are tightened and fixed by the support member 21. Then, the sector plate at the top of the drum is pulled out for inspection using a guide chain. After inspection, it is reinstalled. Then, the support member 21 of the top plate is installed, so that the snap-fit ​​member 22 on the support member 21 is snapped into the groove on the top sector plate to fix the top sector plate. Then, the drum is rotated to rotate the other sector plates to the top. The support component 2 on the next sector plate rotated to the top is removed. The disassembly and inspection of the other sector plates are completed in sequence.

[0038] Importantly, during the disassembly and assembly of the sector plates, this device can assist in fixing other sector plates except for the upper sector plate, preventing them from slipping during the disassembly and assembly of the upper sector plate, effectively solving the safety hazards that may be caused by the slipping of sector plates; this device replaces the operation step of tightening the bottom sector plate guide chain during the replacement of sector plates, saving manpower, and the entire process can be completed by only 2 to 3 people.
