Abstract
A semi-open type three-way flow impeller hoisting device comprises a hoisting plate (1), a disassembly and assembly block (2), a lifting hook (3), a connecting disc (4), a hexagonal bolt (5), a spring washer (6) and an impeller (7). The utility model relates to a semi-open type three-way flow impeller hoisting device with simple structure and strong practicability.
Description
Technical Field
The utility model relates to a semi-open type three-way flow impeller hoisting device which is suitable for hoisting and installing the semi-open type three-way flow impeller during assembly.
Background
The impeller in single-stage and integral tooth-type centrifugal compressor is widely in the form of semi-open ternary flow, and features high strength, high allowable circumferential speed and high single-stage pressure ratio. The semi-open three-way impeller is characterized in that the blades of the semi-open three-way impeller belong to open blades, so that the semi-open three-way impeller must be axially installed when the high-speed rotor set of the compressor is assembled, the impeller is required to be ensured to be horizontal and right against the end face of the high-speed shaft during the axial installation, and the impeller is required to be hoisted by utilizing an auxiliary impeller tool.
Centrifugal compressor impeller belongs to the customization structure, and specification parameter is more, and hoist device should cover impeller and the weight of equidimension as far as possible.
Disclosure of Invention
The utility model aims to provide a semi-open type three-way flow impeller hoisting device with simple structure and strong practicability.
In order to achieve the purpose, the technical scheme is that the device consists of a lifting plate (1), a dismounting block (2), a lifting hook (3), a connecting disc (4), a hexagonal bolt (5), a spring washer (6) and an impeller (7); the lifting device is characterized in that the connecting disc (4) and the impeller (7) are positioned through the spigot and screwed and fixed through the hexagon bolt (5) and the spring washer (6), so that the connecting disc (4) and the impeller (7) are completely attached, the connecting disc (4) is rotationally screwed into the lifting hook (3), the lifting hook (3) is sleeved into the lifting plate (1), the dismounting block (2) is mounted, the lifting hook (3) is placed in a proper position in a semicircular groove of the lifting plate (1), and the gravity center position is confirmed by lifting the whole device.
By adopting the technical scheme, the utility model solves the problem of hoisting impellers of different specifications, ensures the horizontal centering of the impellers during installation, and has good reliability, simple installation and low cost.
Drawings
FIG. 1 is a schematic view of a semi-open three-way flow impeller lifting device of the present utility model;
in the figure: 1. a hanging plate; 2. disassembling and assembling the block; 3. a lifting hook; 4. a connecting disc; 5. a hexagonal bolt; 6. a spring washer; 7. an impeller.
Description of the embodiments
The utility model is further described below with reference to the accompanying drawings.
The technical scheme is that the semi-open three-way impeller hoisting device consists of a hoisting plate (1), a dismounting block (2), a lifting hook (3), a connecting disc (4), a hexagonal bolt (5), a spring washer (6) and an impeller (7); the lifting device is characterized in that the connecting disc (4) and the impeller (7) are positioned through the spigot and screwed and fixed through the hexagon bolt (5) and the spring washer (6), so that the connecting disc (4) and the impeller (7) are completely attached, the connecting disc (4) is rotationally screwed into the lifting hook (3), the lifting hook (3) is sleeved into the lifting plate (1), the dismounting block (2) is mounted, the lifting hook (3) is placed in a proper position in a semicircular groove of the lifting plate (1), and the gravity center position is confirmed by lifting the whole device. By adopting the scheme, the impeller assembly of the single-stage and integral tooth-type centrifugal compressor is simpler and more convenient, the hanging plate (1) is provided with the hanging inlet of the hanging hook (3), so that the hanging of the hanging hook (3) is convenient to take in and out, and meanwhile, the disassembling and assembling block (2) is arranged to prevent the hanging hook (3) from falling off and increase the rigidity of the hanging plate (1).
A semi-open type three-way impeller hoisting device is characterized in that 7 identical semicircular grooves are formed in a hoisting plate (1), the hoisting plate is of an equidistant structure, a lifting hook (3) is placed in a proper position in the semicircular grooves of the hoisting plate (1), the gravity center positions of different impellers are convenient to adjust, and the assembly of the impellers is facilitated.
Therefore, the semi-open type three-way flow impeller hoisting device is simple in structure and high in practicability.
Claims (2)
