Abstract
The utility model discloses a suspension bracket used for allowing a motor rotor to be drawn. The suspension bracket comprises a transversal suspension arm with an elbow. A sleeve is arranged on the end part of the elbow. As a dedicated tool for drawing the motor rotor, the suspension bracket has the advantages of simple and practical structure. When a motor is checked and maintained, the rotor can be conveniently lifted by one step. The suspension bracket can completely replace the prior dummy shaft method for drawing large-medium motors and fill the blank at present.
Description
Technical field
The utility model belongs to the machinery check and repair instrument, is specifically related to a kind of motor rotor that is used for and takes out the suspension bracket of wearing.
Background technology
Large and medium-sized motor need take apart rotor when maintenance, promptly takes out penetrate rotor.Take out penetrate rotor and generally adopt the dummy shaft method.It is to adopt a Gent system steel pipe to prolong rotating shaft, and three cucurbits cooperate the common method of driving lifting.It divides three steps, and the first step is respectively hung a cucurbit with two ends of rotor earlier, and the rotor level is sling, and moves toward a direction.When moving to suspension steel wire dead angle, need put down rotor and carry out second step.Second step put the special steel pipe of a joint at machine shaft one end and prolongs rotating shaft, repeated first step then and extracted rotor out about 1/2.The 3rd step hung on the center of gravity place of rotor with the 3rd cucurbit, undertook the rotor total weight, removed dummy shaft end cucurbit, and level hangs out rotor then.This method operation is very complicated, labour intensity is big, site requirements is high; A motor is taken out axle needs several hrs at least, needs the time at most; And existence destroys electrical machine insulation and personal safety hidden danger.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of motor rotor that is used for to take out the suspension bracket of wearing.Taking out when wearing the large and middle size motor rotor, can disposable easily rotor be hung out with this suspension bracket.
The utility model motor rotor is taken out the tying up frame, comprises that one has the horizontal arm of elbow, is provided with sleeve in the end of elbow.
Further technical scheme is:
The inner surface of described sleeve studs with the brass liner, to increase resistance, prevents that the machine shaft axial plane from scratching;
Also comprise the attached sleeve with different inner diameters that can be enclosed within the described sleeve, the attached inner surface of sleeve studs with the brass liner, and the end of described sleeve and attached sleeve is equipped with ring flange;
The attached sleeve of different inner diameters can be more than one, and each attached sleeve can overlap successively mutually by the internal diameter size.
Take out when wearing rotor, the jacket casing of suspension bracket behind an end of armature spindle, is hooked arm with driving, determine that according to the motor shaft center of gravity hitch point of driving on arm is balance point, slow lift hanger, after rotor was unsettled, level shifted out rotor.Being equipped with the rotor axis of electric that attached sleeve can adapt to the different diameters of axle wears, during use, earlier select attached sleeve for use according to the diameter of axle of rotor axis of electric, with attached jacket casing in the sleeve of arm, be fixed together with the ring flange of bolt sleeve and attached sleeve ends, attached sleeve is fixed on the sleeve, presses the preceding method operation.
Advantage of the present utility model:
1, instrument special use: provide a kind of simple and practical motor rotor that is used for to take out the specific purpose tool of wearing, can replace the dummy shaft method fully and take out and wear large and middle size motor, filled up present vacancy.
2, easy to use: as can convenient power-saving ground is disposable rotor to be hung out, reduced labour intensity, shortened the operating time, do not need to shift maintenance sites.
3, safe and reliable: as can adopt high strength carbon constructional quality steel material, have favorable rigidity and intensity under the full and down, but 3 times of bearing capacities to have guaranteed equipment and personal safety effectively to the weight of extraction out rotor.
4, highly versatile: every equipment can be equipped with a plurality of sleeve assemblies, and a suspension bracket can satisfy multiple different rotor main shaft diameter simultaneously to be used.

Embodiment
Embodiment 1
As shown in Figure 1, the utility model motor rotor is taken out the tying up frame, comprises that one has the horizontal arm 1 of elbow 2, is provided with sleeve 3 in the end of elbow 2, and the inner surface of sleeve 3 studs with brass liner 4.
Embodiment 2
As shown in Figure 2, the utility model also comprises three attached sleeves 8 with different inner diameters that can be enclosed within the sleeve, each attached sleeve 8 can overlap successively mutually by the internal diameter size, each attached sleeve 8 inner surface all studs with brass liner 9, the end of sleeve 3 and attached sleeve 8 is equipped with ring flange 5,6, tightens with bolt 7 between the ring flange 5,6.
Take out with the utility model that to wear the motor rotor operating procedure as follows:
1, as shown in Figure 3, earlier the sleeve 3 of suspension bracket is enclosed within the end of armature spindle 12 of motor 11 after, with 10 balance points that hook arm 1 of driving a vehicle;
2, as shown in Figure 4, slow lift hanger, after rotor was unsettled, driving 10 was shifted out rotor along the arrow horizontal movement.
Claims (4)
