Abstract

A multifunctional large-scale motor rotor lifting appliance relates to the field of manufacturing and repairing of industrial large-scale motors and is used for lifting motor rotors. The device specifically comprises an L-shaped hanging beam, a sleeve, a mounting handle and a fastening bolt. The mounting handle is welded and fixed with the L-shaped hanging beam, the L-shaped hanging beam is welded and fixed with the sleeve, and the fastening bolt is mounted on the sleeve through the threaded hole. When the device is used specifically, an operator operates the lifting appliance through the mounting handle, so that the rotor shaft extends into the lifting appliance sleeve, and the fastening bolts are symmetrically screwed down to clamp and lift.

Description

Multifunctional large-scale motor rotor lifting appliance

Technical Field

The utility model relates to a lifting appliance for lifting a motor rotor in the field of manufacturing and repairing of industrial large motors;

background

The important link of motor assembly is that the rotor part passes through the rabbets at two ends of the stator (base) and is fixed on the base for rotation through an end cover bearing and the like. For small motors, the assembler can load the rotor by manual handling. For large motors, the rotor may weigh up to a ton, and the workshop travelling crane is used for dispatching and assembling. If no special appliance is used for hoisting, the motor rotor is required to be installed in the base, and certain difficulty exists, as shown in the attached figure 1 of the specification, the motor rotor cannot be installed in the motor stator. Generally, a mode of firstly plugging a half of the rotor, dismounting the lifting rope and then hoisting and pulling the lifting rope from the rabbet at the other side is adopted, so that time and labor are wasted, and the stator and the rotor of the motor are easy to damage by collision.

An enterprise uses a single-function L-shaped lifting appliance as shown in the attached figure 2 of the specification, and the problem of assembly of a large rotor can be solved. However, because of the large number of motor models and different sizes of the rotating shaft and the rotor, each motor needs to be manufactured with a specific lifting appliance, the interchangeability is not high, the investment of the product manufacturing period is increased, and on the other hand, no handle is installed or the handle is installed improperly, so that the operation difficulty of workers is increased.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a multifunctional rotor lifting appliance, a lifting appliance can solve the lifting problem of different model rotors. The device specifically comprises an L-shaped hanging beam, a sleeve, a mounting handle and a fastening bolt. The mounting handle is welded and fixed with the L-shaped hanging beam, the L-shaped hanging beam is welded and fixed with the sleeve, and the fastening bolt is mounted on the sleeve through the threaded hole.

The plurality of hoisting holes are formed in the cross beam of the L-shaped hoisting beam, so that the rotors with different lengths and weights can be guaranteed to reach a balanced state after being hoisted.

The cylindrical surface of the sleeve is provided with at least three rows, each row is provided with at least two threaded holes which are symmetrically distributed along the circumferential surface, and the threaded holes are vertical to the cylindrical surface.

The installation handle is two about L shape hanging beam installs, and the installation handle is the character cut in bas-relief shape, and the cross section is cylindrical to make things convenient for workman's operation and increase and hold the comfort.

The rotor shaft is clamped through the threaded hole in the sleeve by the fastening bolt, and rotors with different shaft diameters can be clamped through adjustment of the fastening bolt, so that multiple functions are realized.

Compared with the prior art, the utility model has the following innovative effects:

1. the structure is simple, the manufacture is convenient, the safety and the reliability are realized, and the device is economical and applicable;

2. the lifting device can be used for lifting motor rotors with different types and sizes within a certain range, so that the multifunctional lifting device is multifunctional;

3. the upper and lower mounting handles are added, so that the operation of workers is convenient and comfortable;
