Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Such as figure 1 As shown, a permanent magnet direct drive built-in hoist of the present invention includes a main shaft 15 with a fixed position. Both ends of the main shaft 15 are fixedly arranged on the base base 2, and the main shaft 15 and the base base 2 are fixed with a square hole structure, which is convenient for positioning during installation. The middle part of the main shaft 15 is covered with a rotatable reel 7 . The two ends of the ree...

Abstract

The invention relates to the field of mine elevators, in particular to a permanent magnet direct-driven internally-mounted-type elevator. The permanent magnet direct-driven internally-mounted-type elevator comprises a spindle and a winding drum rotatably arranged on the spindle. A stator coil is fixedly arranged on the position, corresponding to the winding drum, of the spindle along the outer circumference of the spindle, a permanent magnet used for being matched with the stator coil is arranged on the inner wall of the winding drum along the inner circumference of the winding drum, and the outer circumference of the winding drum is used for coiling of a steel wire rope of the elevator. The permanent magnet direct-driven internally-mounted-type elevator has the advantages that the efficiency is high, energy and electricity saving are achieved, the power factor is high, the motor structure is simple, reliability is high, the size is small, the power density is high, the starting torqueis large, noise is small, and the temperature is low.

Description

technical field [0001] The invention relates to the field of mine hoists, in particular to a permanent magnet direct drive built-in hoist. Background technique [0002] Mine hoist is one of the important and key equipment in mines. It is mainly used in coal mines, metal mines and non-metal mines to lift and lower personnel, lift coal, ore, and transport materials and equipment. It is an important means of transportation connecting the mine and the mine, and occupies a very important position in the mine. [0003] With the continuous development of large-scale mines, the development trend of hoists is large-scale, heavy-duty, energy-saving, etc., coupled with national policy guidance, it is particularly important to develop and adopt products with high cost performance, low operating costs, and energy saving and consumption reduction. At present, the structural forms of hoist main shaft devices in use are mainly multi-rope friction type, single-rope winding type and multi-ro...
