Problems solved by technology

[0005] In the existing wireless power transmission technology, E-type, U-type, S-type and other pick-up mechanisms are simple in shape and easy to manufacture, but the coupling performance is not high. The magnetic core is easy to be saturated, and the pick-up mechanisms such as S-type, double-ring and Y-type cannot be applied in the power supply system of the monorail crane.

Abstract

The invention discloses a wireless power supply system of a UT type magnetic core and guide rail type UT type coupling structure, and relates to the field of coupling mechanism design of wireless power supply systems with rail limitation. In order to solve the problems that in an existing wireless power transmission technology, an E-shaped picking mechanism and other picking mechanisms are simple in modeling and low in coupling performance, coupling magnetic cores of double-ring-shaped picking mechanisms and Y-shaped picking mechanisms are prone to saturation, and S-shaped picking mechanisms and other picking mechanisms cannot be applied to a power supply system of a monorail hoist, the technical scheme adopted by the invention is as follows: the wireless power supply system comprises a transmitting guide rail, a receiving coil and a magnetic core; the transmitting guide rail is at least one section, the magnetic core is a UT type magnetic core applied to a guide rail type wireless power supply system and is composed of two parts, one part is of an E-shaped structure, the other part is of a flat plate type structure, and the receiving coil is wound on a stand column in the middle of the E-shaped structure; and the magnetic core is coupled to the launch rail. The method is suitable for being applied to a monorail hoist system adopting a dynamic wireless power transmission technology.

Description

technical field [0001] The invention relates to the field of coupling mechanism design of a track-limited wireless power supply system, in particular to a wireless power supply system with a UT-shaped magnetic core and a rail-type UT-shaped coupling structure. Background technique [0002] The planning and construction of green smart mines put forward higher requirements for the safety of electrical equipment in underground mines with high gas and dust. At present, there are mainly three types of energy supply methods for underground electrical equipment, namely pantograph wire contact power supply, diesel engine power supply and battery power supply. Monorail cranes have been widely used in coal mining transportation systems at home and abroad due to their advantages of strong traction capacity and high work efficiency. The use of contact power supply will cause sparks or even explosions due to the contact of wires; the use of diesel engine power supply is easy to pollute ...
