Description

New stator core hanger

technical field

The utility model relates to an auxiliary tool for installing motor equipment, in particular to a novel stator core hanger, which belongs to the technical field of machinery.

Background technique

When the stator core is installed, it needs to be placed upright to ensure that the winding does not touch the ground, so as to avoid friction and damage to the winding insulation layer. The handling in the prior art usually hoists both ends of the iron core horizontally, and then erects the iron core through manual assembly. This handling method is labor-intensive and low in work efficiency;

In order to improve the rapid lifting of the iron core and ensure the gravity balance when the iron core is hoisted, a sling device is designed; although the existing sling can realize the lifting of the iron core, the sling will be lifted after each lifting. When re-lifting the iron core, the spreader needs to be placed between the iron cores again. When the spreader is lifted and placed, it is necessary to complete a scaling process for the spreader wall bar, that is, the wall bar is retracted as the process of putting the spreader in. The stretching of the wall bar is the process of lifting; the existing spreader cannot automatically lower when it is put in again, and it is necessary to use other parts to restore the spreader to the state when it is not lifted, so as to quickly realize the lifting of the iron core. The operation process Complicated, with many parts, increased costs and reduced work efficiency.

Contents of the invention

In order to solve the above technical problems, the utility model provides a novel stator core hanger, which can realize fast lifting, reduce working intensity and improve working efficiency.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a new stator core hanger, including: a boom, a tensioning mechanism, a hoisting ring, and a stator core; the tensioning mechanism includes a support arm, connected to The support at one end of the support arm is fixed on the suspender. A safety washer is provided between the support and the outer wall of the suspender. The other end of the support arm is connected to one side of the presser foot, and the stator core is placed outside the presser foot. There is wear-resistant rubber between the foot and the stator core, and a lifting ring is provided at the top of the boom;

The support arms are arranged in groups with the boom as the center, at least two groups of upper and lower groups are arranged;

Set at least 2 support arms for each group;

The distance between the presser foot and the boom is less than the length of the support arm;

The support arm and the support are hingedly connected;

The support arm and the presser foot are hingedly connected;

The presser foot is evenly provided with a number of bolt holes in the vertical direction, and the support arms are articulated through the bolt holes of different heights to achieve the required lifting height. At the same time, setting the support arms at different heights can ensure the lifting stability;

Before hoisting, place the stator core on the plane, and then lift the suspender rod so that the width of the whole spreader is smaller than the width of the two stator cores, and put the spreader between the two stator cores, due to the effect of gravity, the support The arm generates a downward swing angle, thereby generating a tension force toward the inner circle of the stator core, and at the same time, the friction between the wear-resistant rubber and the inner ring of the stator core makes the stator core hoist together with the hoist; after hoisting, hoist When the lifting tool is lifted again, no other structure is needed to restore the lifting tool to the lifting state, just put the lifting tool between the two stator cores and give the boom a downward force to prepare for lifting again.

The beneficial effects of the utility model are:

By setting the tensioning mechanism to generate a downward swing angle for the support arm under the action of gravity, the inner circle of the stator core is tightened, and then the stator core is lifted by friction, and the lifting and presetting process of the spreader can realize automatic lifting. No other parts are needed, saving time and labor, saving costs and increasing work efficiency.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing. As shown in Figure 1 and 2,

The novel stator core hanger includes: a boom 9, a tensioning mechanism, a hoisting ring 10, and a stator core 1; the tensioning mechanism includes a support arm 5, a support 7 connected to one end of the support arm 1, and the The support 7 is fixed on the suspender 9, a safety washer 8 is provided between the support 7 and the outer wall of the suspender 9, the other end of the support arm 5 is connected to one side of the presser foot 6, and the stator core 1 is placed on the outside of the presser foot 6 to press A wear-resistant rubber 3 is provided between the foot 6 and the stator core 1, and a lifting ring 10 is provided at the top of the boom 9;

The support arms 5 are arranged in groups with the boom as the center, and at least two groups are arranged up and down;

Each group is provided with 3 support arms 5;

There are 3 presser feet 6;

The wear-resistant rubber 3 is 3;

120° between every two adjacent support arms 5;

The distance between the presser foot 6 and the boom 9 is less than the length of the support arm 5;

The support arm 5 is hingedly connected to the support 7;

The support arm 5 and the presser foot 6 are hingedly connected;

The presser foot 6 is evenly provided with several bolt holes in the vertical direction, and the support arm 5 is articulated through the bolt holes of different heights to reach the required lifting height. At the same time, setting the support arms at different heights can ensure the lifting stability;

Before hoisting, place the stator core 1 on a plane, then lift the suspender boom 9 so that the width of the entire spreader is smaller than the width of the two stator cores 1, and put the spreader between the two stator cores 1, because Under the action of gravity, the support arm 5 generates a downward swing angle, thereby generating a tension force toward the inner circle of the stator core 1, and at the same time, the friction between the wear-resistant rubber 3 and the inner ring of the stator core 1 makes the stator core 1 move along with the spreader. Hoist together; after the hoisting is completed, when the sling is hoisted again, no other structure is needed to restore the sling to the hoisting state, just put the sling between the two stator cores 1 and apply downward force to the boom 9 Ready to lift again.
