[0002] As a key component of a compressor, the impeller directly determines its efficiency and performance. The installation accuracy of the impeller significantly affects the compressor's flow rate and operational stability. However, traditional impeller installation methods have many shortcomings. Currently, the traditional method typically uses a lever principle, employing a long rod as the operating tool. One end of the rod is securely connected to the impeller to be installed, while the other end is manually pressed down to push the impeller in place. This method is not only time-consuming and labor-intensive but also lacks axial angle adjustment capabilities. In actual installation, it suffers from low operational efficiency, high manpower requirements, and low installation accuracy. Therefore, improving impeller installation accuracy, shortening installation time, and reducing labor requirements are urgent problems to be solved. Utility Model Content

[0018] This application provides a hoisting device 100 for assembling an impeller 200, such as... Figures 1-9 As shown, the assembly includes a lifting frame 1, a connecting component 2, a bearing sleeve 4, a main shaft 3, a mounting plate 5, and a wrench 6. The lifting frame 1 is used for lifting. The first end of the connecting component 2 is connected to the lifting frame 1, and the second end of the connecting component 2 is connected to the bearing sleeve 4. The main shaft 3 passes through the bearing sleeve 4. The mounting plate 5 is located at the first end of the main shaft 3 and is used for detachable connection with the impeller 200. The wrench 6 is located at the second end of the main shaft 3 and is used to adjust the position of the impeller 200 through the main shaft 3 and the mounting plate 5.

[0019] The impeller 200 assembly hoisting equipment 100 provided in this embodiment, through the cooperation of the bearing sleeve 4 and the main shaft 3, and the adjustment function of the wrench 6, can accurately control the axial position of the impeller 200, thereby greatly improving the installation accuracy of the impeller 200, ensuring the stability and efficiency of the compressor operation, and reducing the performance degradation problem caused by improper installation.

[0020] The impeller 200 assembly hoisting equipment 100 provided in this embodiment can easily adjust the spatial position of the impeller 200 by lifting the hoisting frame 1 with an overhead crane, which greatly shortens the installation time, improves production efficiency, and reduces the labor intensity of operators.

[0021] The impeller 200 assembly hoisting equipment 100 provided in this embodiment realizes mechanized operation, reducing the need for a large amount of manpower. Operators only need to adjust with a simple wrench 6 to complete the precise positioning of the impeller 200, thereby reducing labor costs. At the same time, the equipment has a simple structure and low cost. The entire tooling can adapt to the installation requirements of impellers 200 of different specifications and models, with high flexibility and versatility, reducing the additional costs and time caused by changing different tooling.

[0022] In one possible implementation, such as Figure 6 and Figure 7 As shown, the connecting assembly 2 includes a connecting body 21, a base plate 22, a first connecting member 23, and a second connecting member 25. The base plate 22 is disposed at the first end of the bearing sleeve 4. The base plate 22 is connected to the connecting body 21 through the first connecting member 23. The first connecting member 23 is connected to the connecting body 21 through the first rivet 24. The second end of the bearing sleeve 4 is connected to the connecting body 21 through the second connecting member 25. The second connecting member 25 is connected to the connecting body 21 through the second rivet 26.

[0023] Understandably, the wrench 6 allows for easier adjustment of the position of the main shaft 3 within the bearing sleeve 4, thereby precisely controlling the axial position of the impeller 200 on the mounting plate 5 and ensuring the installation accuracy of the impeller 200. The lifting frame 1 is connected to the bearing sleeve 4 via the connecting assembly 2, enabling the entire lifting system to be flexibly adjusted in space using an overhead crane to meet the needs of complex installation environments. By using the overhead crane to lift the lifting frame 1, the impeller 200 can be quickly positioned in the designated location, reducing the tedious process of manual handling and positioning, shortening installation time, reducing the need for direct human intervention in the installation of the impeller 200, lowering the labor intensity of operators, and improving work efficiency. The design of the mounting plate 5 and the main shaft 3 allows the lifting equipment 100 to be adapted to impellers 200 of different specifications and models without frequent tooling changes, reducing additional costs and time. The entire lifting equipment 100 has a simple structure, few parts, and is easy to maintain and repair, reducing long-term operating costs.

[0024] Among them, such as Figures 5-7 As shown, the first connector 23 and the base plate 22 are detachably connected, preferably by a snap-fit ​​connection. The snap-fit ​​connection structure enables the first connector 23 and the base plate 22 to be quickly connected and separated, which greatly simplifies the assembly and disassembly process of the equipment. Operators can complete the assembly and disassembly without the aid of additional tools, which significantly improves work efficiency.

[0025] In one possible implementation, such as Figure 8 As shown, the bearing sleeve 4 is used to fit around the main shaft 3 and has a bearing mechanism inside.

[0026] Among them, the bearing sleeve 4 provides stable radial support for the rotating spindle 3 through the internal bearing mechanism, effectively controlling the radial runout and axial movement of the shaft, ensuring the coaxiality and positional accuracy of the transmission system. The tubular bearing sleeve 4 forms a precise fit with the spindle 3, which can not only withstand combined loads, but also achieve fine adjustment of the axial position through adjustment. The sleeve design simplifies the assembly process and facilitates the quick disassembly and maintenance of the spindle 3.

[0027] In one possible implementation, such as Figure 8 As shown, the wrench 6 is connected to the main shaft 3 by power. The second end of the main shaft 3 is provided with a locking tooth 31. The wrench 6 is provided with a protrusion 61. The protrusion 61 is provided with a groove 62 that is adapted to the locking tooth 31. When the locking tooth 31 is inserted into the groove 62, the rotation of the wrench 6 can drive the main shaft 3 to rotate along the axis.

[0028] The precise meshing of the engaging tooth 31 and the slot 62 forms a rigid transmission pair, ensuring the immediacy and accuracy of torque transmission. It can maintain stable transmission even under heavy load conditions and avoid the risk of slippage.

[0029] The protrusion 61 of the wrench 6 facilitates quick alignment and installation. The operator only needs to push the wrench 6 axially to complete the power connection, which significantly shortens the tooling preparation time and reduces the assembly accuracy requirements.

[0030] The protrusion 61 can be positioned in the middle of the wrench 6, so that the operator can apply torque evenly, thereby improving the comfort of operation.

[0031] In one possible implementation, such as Figure 8 As shown, the wrench 6 is detachably connected to the spindle 3. When the engaging teeth 31 are embedded in the slot 62, the wrench 6 can move away from the spindle 3 along the axial direction of the spindle 3 to disengage from the spindle 3.

[0032] Among them, the axial movement unlocking design enables rapid separation. The operator only needs to apply force along the axis of the spindle 3 to complete the disassembly and assembly, which greatly improves efficiency. The engaging teeth 31 (i.e. the hexagonal head end of the spindle 3) automatically disengage during the disassembly process, avoiding the seizing phenomenon common in traditional threaded connections.

[0033] In one possible implementation, such as Figure 4 and Figure 8 As shown, the mounting plate 5 is detachably connected to the impeller 200 by bolts. The mounting plate 5 is provided with at least two through holes, which are adapted to the threaded holes 201 on the end face of the impeller 200. The bolts are inserted through the through holes and the threaded holes 201.

[0034] The alignment design of the through hole and threaded hole 201 simplifies the assembly process. A rigid connection can be completed by inserting bolts, enabling quick disassembly and maintenance of the impeller 200. The evenly distributed structure of multiple holes ensures balanced force and avoids the problem of off-center load caused by single-point connection.

[0035] In one possible implementation, such as Figure 7 As shown, the hoisting frame 1 includes an L-shaped rod, which includes a vertical rod 11 and a horizontal rod 12 connected to each other, and a reinforcing rib is provided between the vertical rod 11 and the horizontal rod 12.

[0036] The L-shaped configuration naturally forms a combination of a vertical load-bearing surface and a horizontal hoisting surface. The right-angle connection between the uprights 11 and the crossbars 12 constitutes a stable force transmission path. The triangular support design of the reinforcing ribs significantly improves the bending stiffness of the nodes, evenly distributing local stress to the overall frame. It can simultaneously resist torsional and shear forces during hoisting, preventing stress concentration cracks at the L-shaped corners.

[0037] In one possible implementation, such as Figure 7 As shown, the hoisting frame 1 also includes a lifting lug 13, and the top of the crossbar 12 is provided with a lifting lug 13 for hoisting.

[0038] Among them, the lifting lug 13 serves as a dedicated stress point, which concentrates the suspended load to the area with the highest strength of the crossbar 12, thus avoiding local deformation of the lifting frame 1 caused by random hanging.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
