Technical Field

The utility model relates to a frock technical field, concretely relates to motor stator hoisting machine constructs.

Background

The motor plays an increasingly important role in the development of various industries in society, and is seen everywhere in the industries of elevators, new energy automobiles, power stations, unmanned vehicles, high-speed rails and the like. Although various large, medium and small motors are developed rapidly, a simple, convenient and safe method for hoisting a stator with large mass is not available. The conventional method for hoisting the stator at present comprises the following steps: (1) for a motor stator with a stator clamping ring, a lifting ring hole is directly additionally arranged on the stator clamping ring, but the clamping ring is very thin, the weight of the stator is relatively heavy, the stator is very easy to deform during lifting, the installation precision of the stator is difficult to ensure, and the method is not suitable for the stator without the clamping ring; (2) prop tight stator interior circle or press from both sides tight stator excircle hoist and mount, but the general design of current frock is complicated, uses the trouble and only relies on frictional force to lift by crane and also hardly guarantees hoist and mount safety to production efficiency is lower.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims at providing a safe and reliable and convenient operation's motor stator hoisting machine constructs.

In order to realize the above purpose, the utility model discloses a motor stator hoisting machine constructs's technical scheme is: including well core rod, well core rod's top is fixed with rings, well core rod's bottom is fixed with props tight dish, the cover is equipped with the sliding sleeve on the well core rod, the articulated lifting claw that is connected with at least three flagging of periphery of sliding sleeve, the lifting claw includes the body of rod and the terminal pothook that is used for of the body of rod colluding on motor stator bottom surface, the pothook sets up outwards, prop the external diameter of tight dish and be greater than the external diameter of movable sleeve, during the use, the lifting claw is arranged in motor stator's hole, the sliding sleeve moves down along well core rod, prop tight dish and strut the.

Detailed Description

The technical solution of the present invention will be described in detail by the following specific examples.

As shown in fig. 1 to 5, including well core rod 1, well core rod 1's top is fixed with rings 2, well core rod 1's bottom is fixed with props tight dish 5, well core rod 1 goes up the cover and is equipped with sliding sleeve 3, the articulated three flagging claw 4 that is connected with of sliding sleeve 3's periphery, lifting claw 4 includes the body of rod 41 and the terminal pothook 42 that is used for colluding on the motor stator bottom surface of the body of rod 41, pothook 42 sets up outwards, prop tight dish 5's external diameter and be greater than the external diameter of movable sleeve 3, during the use, lifting claw 4 is located motor stator 6's hole, sliding sleeve 3 moves down along well core rod 1, prop tight dish 5 automatic with lifting claw 4 and strut.

In this embodiment, the periphery of the sliding sleeve 3 is provided with a radial connecting plate 31, the top end of the lifting claw 4 is hinged to the connecting plate 21 through a bolt and a nut, the lifting claws 4 are uniformly distributed on the periphery of the sliding sleeve 3, and the lifting claws 4 can rotate around the central rod 1 along with the sliding sleeve 3. The hook 42 and the rod 41 form an obtuse angle, and the specific angle can be calculated according to the inner diameter of the suspended stator. The lifting ring 2 is detachably mounted on the central rod 1 by a threaded connection. The tightening disc 5 is disc-shaped and is perpendicular to the central rod 1.

In other embodiments, the number of the lifting claws may be four when the weight of the motor stator is large.

The working principle is as follows: the hoisting mechanism is located in an inner hole of the motor stator, the bottom of the motor stator is heightened, the height of the hoisting mechanism is larger than that of the clamping hook, when the hoisting ring is stressed to drive the tightening disc to move upwards, the clamping hook of the hoisting claw is expanded, the upper surface of the clamping hook on the hoisting claw is in contact with the bottom surface of the stator to serve as a bearing surface, after the motor stator is moved to a destination, the hoisting ring unloads force, the central rod and the tightening disc fall due to dead weight, the sliding sleeve moves upwards relative to the central rod, the hoisting claw is folded therewith, and the hoisting mechanism is disassembled. The operation is simple and convenient, safe and reliable, the production efficiency is improved, and the production cost is reduced. The hoisting mechanism can be widely popularized, and solves the problem that various heavy stators in the motor industry of China are inconvenient to hoist and transport.

Before improving, current stator hoist and mount transportation is extremely inconvenient, often has the stator to damage because of hoist and mount transportation, and the hoist and mount efficiency is several times original after improving, and the security improves greatly, very big reduction the manufacturing cost of motor.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
