Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, specifically to a tooling for assembling a compressor impeller and volute. Background Technology

[0002] The compressor consists of an impeller and a volute. Due to the high precision required for assembly, lifting fixtures are needed when assembling the impeller and volute.

[0003] The existing tooling mainly consists of a crossbeam and a boom. A connecting plate is fixed at the bottom of the boom. By connecting the connecting plate to the impeller, the impeller can be lifted. However, the above tooling can only lift one type of impeller, which is not versatile and cannot meet the assembly requirements of multi-level impellers.

[0004] In summary, the existing tooling can only be used to lift impellers of one level, which results in poor versatility and an inability to meet the assembly requirements of impellers of multiple levels. Utility Model Content

Therefore, this invention provides a tooling for assembling compressor impellers and volutes.

[0006] The technical solution of this utility model is: a tooling for assembling a compressor impeller and a volute, comprising: a crossbeam, the crossbeam being horizontally arranged, a lifting lug being connected to the top of the crossbeam, and the lifting lug having a lifting hole;

[0007] A vertical beam is installed vertically at the bottom end of the horizontal beam;

[0008] A detachable connector and a connecting plate, wherein the connector is horizontally mounted on the vertical beam and located on the same side as the horizontal beam, and the connecting plate is detachably connected to the impeller;

[0009] The connecting plate has a central hole in the middle for positioning with the impeller. There are multiple connecting plates, and the diameter of the central hole of each connecting plate is different. By replacing the connecting plates, the assembly of multi-level impellers can be achieved.

[0010] Furthermore, the connector includes a first adapter plate and a second adapter plate arranged in parallel at intervals, and the first adapter plate and the second adapter plate are connected by a steel pipe.

[0011] Furthermore, the second adapter plate is detachably connected to the connecting plate by bolts, and one side of the second adapter plate has a circular groove for positioning with the connecting plate.

[0012] Furthermore, the steel pipe has a plurality of segments evenly distributed along the circumference.

[0013] Furthermore, the lifting holes have a plurality of holes spaced apart along the length of the lifting lug.

[0014] Furthermore, it also includes: a first stiffening plate, connected between the crossbeam and the vertical beam.

[0015] Furthermore, it also includes a second stiffening plate, connected between the vertical beam and the connector.

[0016] Furthermore, both the horizontal beam and the vertical beam are I-beams.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The tooling provided by this utility model for assembling compressor impellers and volutes has a central hole in the connecting plate that can position the impeller. After positioning, the connecting plate and the impeller are fixed first, and then the connecting plate is fixed on the connecting piece. The impeller can be lifted through the lifting hole. By changing different connecting plates, the assembly of multi-level impellers can be achieved, which is highly versatile.

[0019] The tooling provided by this utility model for assembling the compressor impeller and volute has a connecting piece that serves as an intermediate connection, which reduces the thickness of the connecting plate, making it easier to replace the connecting plate, and also avoids interference between the vertical beam and the impeller.

The crossbeam 1 is horizontally positioned, with a lifting lug 2 connected to its top. The lifting lug 2 has a lifting hole 3. The vertical beam 4 is vertically installed at the bottom of the crossbeam 1. The vertical beam 4 and the crossbeam 1 are welded together. The lifting lug 2 and the crossbeam 1 are also welded together. The connecting piece 5 and the connecting plate 6 are detachably connected. The connecting piece 5 is horizontally installed on the vertical beam 4 and is located on the same side as the crossbeam 1. The connecting plate 6 is detachably connected to the impeller 7 by bolts. The connecting plate 6 has a central hole 8 in its middle position for positioning with the impeller 7. There are multiple connecting plates 6, and the diameter of the central hole 8 of each connecting plate 6 is different. By replacing the connecting plates 6, the assembly of multiple levels of impeller 7 can be achieved.

[0026] The tooling for assembling the compressor impeller and volute in this embodiment has a central hole 8 in the connecting plate 6 that can position the impeller 7 at the stop. After positioning, the connecting plate 6 and the impeller 7 are fixed first, and then the connecting plate 6 is fixed on the connecting piece 5. The impeller 7 can be lifted through the lifting hole 3. By changing different connecting plates 6, the assembly of multi-level impellers 7 can be achieved, which is highly versatile.

[0027] Specific Implementation Method Two: Combining Figure 2 , Figure 3 This embodiment differs from specific embodiment one in that the connecting component 5 includes a first adapter plate 9 and a second adapter plate 10 arranged in parallel at intervals. The first adapter plate 9 and the second adapter plate 10 are connected by a steel pipe 11. The first adapter plate 9 is welded to the vertical beam 4. The steel pipe 11 is also welded to the first adapter plate 9 and the second adapter plate 10, serving as an intermediate connector. The connecting component 5 has a simple overall structure and high strength, meeting hoisting requirements. The longer length of the steel pipe 11 prevents interference between the vertical beam 4 and the impeller 7. Other components and connections are the same as in specific embodiment one.

[0028] Specific implementation method three: Combining Figure 2 , Figure 3 This embodiment differs from specific embodiment two in that the second adapter plate 10 is detachably connected to the connecting plate 6 via bolts.
