Abstract
A lifting-dedicated tool for disassembling a motor rotor is applied to lifting the motor rotor in motor repair and maintenance. A disc-shaped weight-balancing disc is fixed at one end of a cylinder-shaped crossbeam; an upright column is vertically welded at the other end of the crossbeam; a sleeving is welded at the other end of the upright column; the upright column is welded on an external wall of the sleeving; the center lines of the crossbeam, the upright column and the sleeving are at the same plane; steel wire ropes are welded at external walls of two ends of the crossbeam; and a hook of the steel wire ropes is arranged at a side opposite to the upright column. The lifting-dedicated tool is advantageous in that the tool can safely lift the motor rotor in motor repair and maintenance; and the tool can eliminates the defects of great difficulty in motor rotor disassembly and proneness to damaging and crashing a coil when workers repair the motor rotor.
Description
Technical field
The utility model relates to large-size machine maintenance technique field, and particularly a kind of motor is got the rotor lifting specific purpose tool.
Background technology
In modern industry was produced, motor was indispensable equipment, is widely used in all trades and professions.When motor maintenance and maintenance, often need rotor is extracted out from stator, tens kilograms of large and medium motor rotor weights are to the hundreds of kilogram.At present, rotor is extracted in dismounting when this class motor maintenance and maintenance, needs 4～6 skilled staffs, employ hanging device and cooperatively interact, repeatedly mobile, repetitive operation could be extracted rotor out from stator, this method staff labor intensity is larger, and it is high that mutual tacit degree is wanted; The extraction process rotor might collide the potential safety hazard that motor coil causes the coil damage, injures by a crashing object.
The utility model content
The purpose of this utility model is: provide a kind of motor to get the rotor lifting specific purpose tool, can lift by crane safely rotor, overcome employee's rotor dismounting difficulty when motor maintenance and maintenance large, the defective that easily cause the coil damage, injures by a crashing object.
The technical solution adopted in the utility model is: motor is got the rotor lifting specific purpose tool, comprise crossbeam, balancing disk, column and sleeve pipe, it is characterized in that: the end at tubular crossbeam is fixed with discoidal balancing disk, the other end at crossbeam is vertically welded with a column, column is cylindrical, the other end at column is welded with sleeve pipe, and column is welded on the outer wall of sleeve pipe; The center line of crossbeam center line, column center line and sleeve pipe is in same plane; Be welded with the steel wire rope hook at the two ends of crossbeam outer wall, the hook of steel wire rope is in a relative side of column.
For fear of the bite axle of rotor of sleeve edge, sleeve pipe centre bore edge is arc surface shape, and casing inner diameter is than the large 0.5mm of shaft diameter of rotor.Motor rotor just moves and can not cause motor rotor and stator coil to collide.
The use procedure that the summary motor is got the rotor lifting specific purpose tool.Consult Fig. 1.One end of rotor 7 axles is inserted in the sleeve pipe 6.The two ends of steel wire rope 2 are connected on the steel wire rope hook.Hook of hoist 1 hangs over the middle part of steel wire rope 2.Slowly lift by crane rotor 7.Hook of hoist 1 moves right, and drive motor rotor 7 moves out from motor stator.
The beneficial effects of the utility model: the utility model motor is got the rotor lifting specific purpose tool, in motor maintenance and the maintenance, can lift by crane safely rotor, overcome employee's rotor dismounting difficulty when motor maintenance and maintenance large, the defective that easily cause the coil damage, injures by a crashing object.
Description of drawings
Fig. 1 is that the utility model motor is got rotor lifting specific purpose tool structural representation.
Among the figure, 1-hook of hoist, 2-steel wire rope, 3-crossbeam, 4-balancing disk, 5-column, 6-sleeve pipe, 7-rotor.
Embodiment
Embodiment 1: get the rotor lifting specific purpose tool as example take a motor, the utility model is described in further detail.
Consult Fig. 1.The utility model motor is got the rotor lifting specific purpose tool, comprises crossbeam 3, balancing disk 4, column 5 and sleeve pipe 6.
Crossbeam 3 diameter 59mm, length 1200mm.End at tubular crossbeam 3 is fixed with discoidal balancing disk 4, is vertically welded with a column 5 at the other end of crossbeam 3, and column 5 is cylindrical, and the diameter of column 5 is 50mm, length 700mm.The other end at column 5 is welded with sleeve pipe 6, sleeve pipe 6 external diameter 130mm, and internal diameter 91mm, sleeve pipe 6 internal diameters are than the large 0.5mm of shaft diameter of rotor 7.Sleeve pipe 6 centre bore edges are arc surface shape.Column 5 is welded on the outer wall of sleeve pipe 6; The center line of crossbeam 3 center lines, column 5 center lines and sleeve pipe 6 is in same plane; Be welded with the steel wire rope hook at the two ends of crossbeam 3 outer wall, the hook of steel wire rope is in a relative side of column 5.
Claims (2)
1. a motor is got the rotor lifting specific purpose tool, comprise crossbeam (3), balancing disk (4), column (5) and sleeve pipe (6), it is characterized in that: the end at tubular crossbeam (3) is fixed with discoidal balancing disk (4), the other end at crossbeam (3) is vertically welded with a column (5), column (5) is cylindrical, the other end at column (5) is welded with sleeve pipe (6), and column (5) is welded on the outer wall of sleeve pipe (6); The center line of crossbeam (3) center line, column (5) center line and sleeve pipe (6) is in same plane; Two ends outer wall at crossbeam (3) is welded with the steel wire rope hook, and the hook of steel wire rope is in a relative side of column (5).
2. motor according to claim 1 is got the rotor lifting specific purpose tool, it is characterized in that: sleeve pipe (6) centre bore edge is arc surface shape; Sleeve pipe (6) internal diameter is than the large 0.5mm of shaft diameter of rotor (7).
