Modular structure of motor stator and outer rotor of mine hoist

Abstract

The invention relates to a mine hoist, in particular to a modular structure of a motor stator and an outer rotor of a mine hoist. The modular structure comprises the stator, a rotor case and a staticspindle, the stator is mounted on the static spindle in a sleeving manner through a supporting frame, the rotor case is mounted on the stator in a sleeving manner and connected with the static spindlethrough an end cover and a bearing, the stator comprises a stator magnetic pole module and a stator support, stator teeth are arranged on the stator magnetic pole module, a coil is mounted on the stator teeth in a sleeving manner, a guide rail is arranged on the lower portion of the stator magnetic pole module, a guide groove matched with the guide rail is formed in the stator support, and the guide rail of the stator magnetic pole module is mounted in the guide groove of the stator support. According to the modular structure, the modular stator magnetic pole module and a modular stator magnetic pole module are separately disassembled, replaced and mounted without destroying a friction drum, mounting and maintaining of devices are facilitated, working cycle is shortened, and maintaining cost is reduced.

Description

technical field [0001] The invention relates to a mine hoist, in particular to a modular structure of a motor stator and an outer rotor of the mine hoist. Background technique [0002] In our country, the mine hoist manufacturing industry has experienced more than 60 years of development and has made great progress. The products include JK series single-rope winding hoist, JKM(D)E series multi-rope friction hoist, the transmission form is motor-reducer-hoist drum, the motor is a high and low voltage asynchronous motor, and later developed into a motor - The form of direct connection of the hoist drum. In recent years, hoist manufacturers and motor manufacturers at home and abroad have also jointly manufactured larger mine hoists with a suspension transmission structure in which the drum and the main synchronous motor are directly connected. The transmission motor is a DC motor or an AC synchronous motor. Electric motors have been successfully applied in mines. [0003] At ...

AI Technical Summary

Problems solved by technology

This structure makes full use of the advantages of built-in compact structure, space saving, symmetrical transmission of wire rope tension and magnetic tension, and also utilizes the characteristics of energy saving and high efficiency of permanent magnet motor, no need for DC excitation, no slip ring and brush structure, and simple maintenance. , but the motor rotor support structure and the reel support structure are set independently, and four bearing fulcrums are still used. At the same time, the motor rotor and the reel are independently designed and connected by a flexible connection mechanism, resulting in the disadvantages of complex structure, difficult assembly, and increased weight.

[0009] At the same time, the stator and permanent magnet rotor of the traditional built-in hoist cannot be taken out of the drum alone. When on-site maintenance is required, the drum can only be disassembled and then operated. The operation is difficult, the cycle is long, and the cost is high, causing the mine to stop production.
