Description
Technical field
the utility model belongs to hoisting sling, specifically a kind of permanent magnetic lifting device.
Background technology
hoisting permanent magnet, lifting electromagnet, be widely used in the industries such as steel plant, steel warehouse, steel scrap treatment plant, shipbuilding yard, massive casting factory, heavy-duty machinery originating firm, port and pier and station.Its major product type comprises:
1, small-sized hoisting permanent magnet: the magnetic Circuit Design that adopts single shaft, single magnetic circuit gap, determine that this class permanent magnetic lifter only has stronger Surface field intensity, and can not there is the larger magnetic field degree of depth, also just can not be applied on large lifting equipment, the more impossible waste suction steel that is applied to, be only limited to the lifting of smallclothes planar member, its application is confined to little tonnage (inhaling flat part, planar member pulling-out force≤5000Kg); Other utilize the permanent magnet sucking hoisting apparatus of lever construction specially to inhale flat board, can not close magnetic field, and it uses very limitation.
2, traditional lifting electromagnet: control the advantages such as convenient, the magnetic field degree of depth is large owing to having, be widely used at present industry-by-industry.But it also has following shortcoming: 1. easily fall steel when fault, and dangerous; 2. produce magnetic field by electricity, power consumption; 3. have a power failure and need power-off protection; 4. have hysteresis, work efficiency is low; 5. use for a long time temperature rise, lifting power declines large; 6. service expenditure is large; 7. the life-span is short; 8. towing cable operation.Above problem is to perplex for a long time the hard nut to crack of lifting electromagnet always, there is no all the time substantive solution.
Chinese patent 02138572.6 discloses a kind of Magnetic circuit switch that can be used for permanent magnetic lifting device, it include be arranged in permanent magnetism casing by the rotary magnet in two rotating shafts and some fixed magnets, two (many) axles of they common formations, two (many) gaps magnetic circuit, not only there is very high Surface field intensity, and there is the suitable magnetic field degree of depth, but because permanent magnetism box sizes is little, the moment of torsion of two rotating shaft demand motives is very large, the various driving device structures of current this structure are too complicated, fluid pressure drive device uses easy oil leakage for a long time, other mechanical actuation device is short service life, maintenance cost is high, transmission operational reliability is low.
utility model content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, reliable, save the permanent magnetic lifting device with higher magnetic field and the larger magnetic field degree of depth of electric energy.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of permanent magnetic lifting device, comprise a permanent magnetism case, be provided with by two separately-driven two rotary magnets of rotating shaft in described permanent magnetism case, the rotation of two rotating shafts can open and close permanent magnetic circuit; Two rotating shaft horizontal Tiles arrange, and the end of two rotating shafts is separately installed with transmission gear; Described permanent magnetic lifting device also comprises a driven wheel, and described driven wheel is driven by the motor with braking function, and described driven wheel synchronously rotates by two transmission gear reversing senses of intermediate gear drives.
On described intermediate gear or transmission gear, be provided with anodontia section and have tooth section, make described driven wheel be merely able to drive transmission gear to rotate 0 by intermediate gear
.-110
。angular range.Ensure that from structure the angular range that rotary magnet rotates is 0
.-110
。, ensure safety.
On described intermediate gear or transmission gear, be symmetrically arranged with two sections and have tooth section.
On the shell of described permanent magnetism case, be symmetrically arranged with at least two hangers.
The utility model has the advantages that: control the moment electricity consumption of Magnetic circuit switch, then by permanent magnetic field lifting and carrying, not power consumption, saves electric energy.Adopt gear transmission, the design of transmitting torque maximizing, long service life, substantially non-maintaining, equipment is reliable.Being symmetrically arranged with two sections has tooth section, when one period of when wearing and tearing wherein, then uses another section, has reduced the waste of material.
