Description

Technical Field

[0001] The invention relates to a tooling device for disassembling and assembling a heavy-weight lifting lug of a shielded motor. Background Art

[0002] With the development and progress of society, the production and manufacturing technology of motors has become more and more sophisticated. In order to meet the performance requirements of motors, the shape and size of motors are increasing. In order to meet the production and manufacturing of large motors, the size of the supporting special lifting tools is also gradually increasing. Due to the appearance or shape design requirements of the motor, the disassembly and assembly of some special lifting tools cannot be directly lifted by lifting equipment due to the needs of the workstation or other reasons, and the weight of the lifting lug cannot be carried by manpower. Therefore, a tooling device is needed to meet the disassembly and assembly of large lifting lugs without lifting equipment or without lifting equipment. The traditional disassembly and assembly method is to use a jack to directly support the lifting ear. Because the bolts need to be disassembled and assembled, the jack can only be supported on the raised part of the lifting ear. The raised part of the lifting ear is an inclined surface. After the jack is tightened, it is not firm and it is easy to fall off and injure the operator, causing a safety accident. The tooling device perfectly solves this problem. After reserving space for disassembly and assembly of the bolts, it can also provide perfect support without the risk of workpiece falling off. It is easy to operate and saves space. The lifting ear is easy to transport after removal, and can perfectly meet the disassembly and assembly needs of large lifting ears. Summary of the invention

[0004] The mobile vehicle body (1) is composed of a top plate (13), a front end vertical plate (14), a back vertical plate (15), a column (16), a wheel frame (12), a handle (17) and a bottom plate (18) assembled and welded, wherein the top plate (13) is connected to the front end vertical plate (14) in a vertical direction, the other end of the top plate (13) is connected to the back vertical plate (15) in a vertical direction, the top plate (13) and the bottom plate (18) are connected through a plurality of columns (16), the wheel frame (12) is installed at the lower part of the bottom plate (18), a fixed handle (17) is installed on one end of the top plate (13), a thread hole (8) is provided on a fixed base (2) of the bottom plate (18), a sink groove (9) for installing a supporting pad (3) and an adjusting gasket (5) is processed on the top plate (13), and a large lifting ear (10) is reserved for protruding sliding crotch distance when the front end vertical plate (14) is welded, so as to facilitate the installation and matching of the lifting ear and the mobile vehicle body (1).

[0005] The working principle of the present invention is:

[0006] When removing the lifting ear, first assemble the various parts into a whole, adjust the fixed base of the lifting ear disassembly and assembly device to be higher than the wheel, push the trolley to the bottom of the lifting ear, align the countersunk groove on the trolley with the engaging bolts of the lifting ear one by one, adjust the fixed base, lift the trolley to lift the wheel off the ground so that it cannot move freely and adjust the upper surface of the car body to be horizontal, lock the fixed base, fill the gap between the countersunk groove and the mounting bolt with the supporting plate and adjusting gasket, remove one of the bolts first, and fill the countersunk groove and the lower end face of the lifting ear after removing the mounting nut with the supporting plate and adjusting gasket, then repeat the above operation, remove the bolts one by one, adjust the fixed base down, and push the trolley and the lifting ear away together.

[0007] When installing the lifting ear, push the trolley and the lifting ear together to the bottom of the workpiece, align the lifting ear with the installation position on the workpiece, adjust the fixed base to make the lifting ear and the workpiece fit completely, remove a gasket that holds the bolt, install the bolt, insert the support pad and adjustment gasket, repeat the above steps, install the remaining bolts in turn, and push the trolley away.

[0009] When installing the lifting ear, push the trolley and the lifting ear together to the bottom of the workpiece, align the lifting ear with the installation position on the workpiece, adjust the fixed base to make the lifting ear and the workpiece fit completely, remove a gasket that holds the bolt, install the bolt, insert the support pad and adjustment gasket, repeat the above steps, install the remaining bolts in turn, and push the trolley away.

[0010] The beneficial effects of the present invention are:

[0011] A freely movable installation vehicle is used to provide a tooling device for disassembling and assembling large lifting eyes in working conditions where there is no lifting equipment or the lifting equipment cannot be used. This device not only frees the lifting equipment from restrictions, but is also simple and convenient to operate. It is small in size and light in weight, and can be used at any time, reducing the operator's work difficulty and operation time. This tooling device can also be used as a storage station for the lifting eyes, which can be freely transported by manpower, thus avoiding the problem of inconvenient transportation and storage due to the lifting eyes being too large or too heavy.

[0012] The traditional disassembly and assembly method is to use a jack to directly support the lifting ear. Because the bolts need to be disassembled and assembled, the jack can only be supported on the raised part of the lifting ear. The raised part of the lifting ear is an inclined surface. After the jack is tightened, it is not firm and it is easy to fall off and injure the operator, causing a safety accident. The tooling device perfectly solves this problem. After reserving space for disassembly and assembly of the bolts, it can also provide perfect support without the risk of workpiece falling off. It is easy to operate and saves space. The lifting ear is easy to transport after removal, and can perfectly meet the disassembly and assembly needs of large lifting ears. BRIEF DESCRIPTION OF THE DRAWINGS
