Description

Tooling for easy disassembly and assembly of the fan's double impeller Technical Field

[0001] This utility model relates to a device for disassembling and assembling the impeller of a sanitation cleaning vehicle, and particularly to a tooling for facilitating the disassembly and assembly of a double impeller of a fan. Background Technology

[0002] The core component of a sanitation vehicle is the centrifugal fan, and the most difficult parts to assemble are the impeller and the shaft.

[0003] The assembly of the impeller and shaft is generally done with special tools, which are usually hydraulically driven cylinders. These tools require hydraulic pumps, hydraulic tanks, hydraulic lines and cylinders, making the structure complex. Moreover, the fan needs to be moved to a fixed location to disassemble and assemble the impeller, which is not conducive to the convenience of maintenance.

[0004] If no special tools are available for disassembly and assembly, a hammer or mallet can be used. However, using a hammer or mallet can easily damage the axle and hub, which is unsafe.

[0005] Furthermore, the above method is particularly inconvenient for the installation and disassembly of dual impellers. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a tooling for easy disassembly and assembly of the double impeller of a fan, so as to achieve safe and convenient disassembly and assembly of the double impeller of the fan in a sanitation vehicle.

[0007] To solve the above-mentioned technical problems, the present invention provides a tooling for convenient disassembly and assembly of a dual impeller for a fan, comprising a slot on a rotating shaft, a tooling locking bolt, an impeller disassembly bolt, a tooling disassembly block, and an impeller tensioning bolt. The tooling disassembly block consists of a large ring block and a small ring block, which are fixedly connected and fixed to the slot on the rotating shaft by the tooling locking bolt. The impeller has a threaded connection hole, and the tooling disassembly block has a connection hole. When installing the impeller, the impeller tensioning bolt passes through the connection hole on the tooling disassembly block and is threadedly connected to the threaded connection hole on the impeller to tighten the impeller and the tooling disassembly block. The tooling disassembly block also has a threaded connection hole. When disassembling the impeller, the impeller disassembly bolt is tightened by tightening the threaded connection hole on the tooling disassembly block to push the impeller apart.

[0008] The connecting holes of the tooling assembly / disassembly block are located on the large ring block.

[0009] The threaded connection hole of the tooling assembly / disassembly block is located on the large ring block.

[0010] There are two slots on the rotating shaft.

[0011] The two slots on the rotating shaft are located between the two impellers.

[0012] The tooling assembly / disassembly block has two connecting holes symmetrically arranged along its axis.

[0013] The tooling assembly / disassembly block has two threaded connection holes symmetrically arranged along the axis.

[0014] The structure of this utility model features a slot on the rotating shaft. The tooling assembly / disassembly block consists of a large ring block and a small ring block. During operation, the large and small ring blocks are first fixedly connected and secured to the slot on the rotating shaft using tooling locking bolts. Then, the impeller is installed or disassembled using impeller tensioning bolts or impeller removal bolts. When installing the impeller, the impeller tensioning bolt passes through the connecting hole on the tooling assembly / disassembly block and is threaded into the threaded connecting hole on the impeller to tighten the impeller and the tooling assembly / disassembly block. After installation, the tooling assembly / disassembly block and tensioning bolts can be removed. When disassembling the impeller, the impeller removal bolt is tightened into the threaded connecting hole on the tooling assembly / disassembly block to push open the impeller. After disassembling the impeller, the removal bolt can be removed.

[0015] Using this invention, the entire installation and disassembly process does not require complicated tools and will not cause damage, making it both safe and convenient.

[0016] This invention has a simple and reliable structure, which greatly reduces costs. Attached Figure Description

[0019] Figure 3 is a schematic diagram of the tooling assembly / disassembly block structure of this utility model. Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0021] As shown in Figures 1, 2, and 3, the tooling for easy disassembly and assembly of the dual impellers of the present invention includes a slot on the rotating shaft 1, a tooling locking bolt 2, an impeller disassembly bolt 4, a tooling disassembly block 5, and an impeller tensioning bolt 6.

[0022] The tooling assembly / disassembly block 5 consists of a large ring block 51 and a small ring block 52. During operation, it is fixedly connected to and fixed to the slot on the rotating shaft by the tooling locking bolt 2.

[0023] The impeller 3 has a threaded connection hole. Alternatively, a nut can be directly welded into the threaded connection hole during manufacturing. The tooling disassembly block 5 has a connection hole 7. When installing the impeller, the impeller tensioning bolt 6 passes through the connection hole on the tooling disassembly block 5 and is threaded into the threaded connection hole on the impeller 3 to tighten the impeller and the tooling disassembly block. After installation, the tooling disassembly block and tensioning bolt can be removed.

[0024] The tooling disassembly block 5 is also provided with a threaded connection hole 8. When disassembling the impeller, the impeller disassembly bolt 4 is tightened by tightening the threaded connection hole 8 on the tooling disassembly block 5 to push the impeller apart. After disassembling the impeller, the disassembly bolt and the tooling disassembly block can be removed.

[0025] Preferably, the connecting hole 7 of the tooling disassembly block 5 is located on the large ring block 51. The threaded connecting hole 8 of the tooling disassembly block 5 is also located on the large ring block 51.

[0026] Suitable for dual-impeller fans, with two slots on the rotating shaft 1. The two slots on the rotating shaft 1 are located between the two impellers.

[0027] To facilitate balanced assembly and disassembly, two connecting holes 7 are symmetrically arranged along the axis of the tooling assembly and disassembly block 5. Two threaded connecting holes 8 are also symmetrically arranged along the axis of the tooling assembly and disassembly block 5. In this way, during operation, by alternately tightening the bolts from the top and bottom, damage caused by misalignment between the shaft and the impeller hub can be prevented, and smooth axial movement of the impeller can be achieved.
