Description
The utility model relates to a kind of hoisting force that is used for transmitting, and with the lifting mechanism bonded assembly magnetic hoisting sling of hoisting crane, is a kind of rare earth permanent magnet hoisting sling specifically.
General-duty magnetic hoisting sling is concluded two classes both at home and abroad at present: a class is the electromagnetism hoisting sling, and another kind of is the permanent magnet hoisting suspender.This two classes magnetic hoisting sling respectively has merits and faults, though that the electromagnetism hoisting sling is inhaled thing and unloaded thing is easy to operate, need uninterrupted power supply continuously to use, and the big more consumption of current of hoisting capacity is also big more; In order to prevent accident power-off generation safety misadventure, charge power supply that also must the configuration rates costliness; In addition also exist and inhale shortcomings such as anharmonic ratio is little.Though permanent magnet hoisting suspender power saving, but when laying down the suction thing, must apply external force and could discharge weight, especially ferrite and Al-Ni-Co permanent magnet lifting magnet, not only hoisting capacity is less, and unloading heavy and to inhale under the heavy two states change of magnetic field strength little, be with a large amount of iron filings to cause the not firm safety problem that occurs of its suction weight because of easily inhaling.Also have parallel-moving type or rotary type rare earth permanent magnet lifting electromagnet now, be to adopt the series connection of two magnetic circuit systems of permanent magnetism and short circuited operating mode to reach the purpose that weight is put in suction, though this structure lifting electromagnet has permanent magnetism degree of utilization height, the suction anharmonic ratio is big, long service life, advantage such as safe and reliable, but will realize the translation of magnetic circuit system or rotate then must configuration corresponding driving device, this makes the volume of suspender and power consumption increase again, and operation is also inconvenient.
The purpose of this utility model provides a kind of power saving, and the suction anharmonic ratio is big, and cost is low, and is easy and simple to handle, safe and reliable, the rare earth permanent magnet hoisting sling of long service life.
The utility model is improved realization on electromagnetism hoisting sling architecture basics, promptly in the electromagnetism hoisting sling, set up an annular rare-earth permanent magnet, and the input end of the coil of electromagnetism hoisting sling is connected with a direct current high-voltage pulse power source, utilize the interactional magnetic Circuit Design in DC pulse principle and magnetic field, moment positive charge with pulse picks up weight, reverse charging discharges weight, and the lifting weight need not continuous power supply in operational process.Specifically, a kind of rare earth permanent magnet hoisting sling, it comprises cylindrical housing, with shell upper end bonded assembly gland, gland central authorities are provided with screw flight bonded assembly suspension ring, be provided with in the shell and the cylindrical yoke of its coaxial arrangement pulsed coil outer with being enclosed in yoke, the upper end of yoke is connected with gland, on the framework of pulsed coil, the lower end is respectively equipped with shock ring, wherein gland is the magnetic screening gland, outside yoke, the top of pulsed coil also is provided with annular rare-earth permanent magnet, and the magnetic pole of permanent magnet is an axial distribution, is provided with the magnetic shading ring between yoke downside and outer casing bottom, be provided with the magnetic isolating pad between the bottom of yoke center of top and suspension ring screw rod, the input end of pulsed coil is connected with the high direct voltage pulse power.
In the utility model, utilize high direct voltage pulse power paired pulses coil moment positive charge, produce the pulsed magnetic field identical with the rare-earth permanent magnet magnetic direction, this pulsed magnetic field and rare-earth permanent magnet magnetic field is superposition mutually, make magnetic flux increase in the yoke, increase suspender suction, pick up weight; High direct voltage pulse power paired pulses coil is with the moment reverse charging, just produce the pulsed magnetic field opposite with the rare-earth permanent magnet magnetic direction, this pulsed magnetic field and rare-earth permanent magnet magnetic field offset, magnetic flux in the yoke is weakened greatly, suspender suction sharply descends, discharge weight, and lifting and release function key employing safety and interlock device, make lifting and releasing operation safe and reliable.In the lifting of employing DC pulse control suspender and the magnetic Circuit Design of release weight, instantaneous power supply, long-term use, needn't as Electromagnetic slings for lifting loads, want uninterrupted power supply continuously and configuration safe spare power supply, power saving rate reached more than 90% when this suspender used, remarkable energy saving effect is not only arranged, and reduced cost.This suspender rare earth degree of utilization is very high, and the suction anharmonic ratio is also very big, and its rare earth degree of utilization is 200～400, and inhaling anharmonic ratio is 16～40.The maximum suction of unit area is 4.72kg/cm
2, the unit area rated attraction force is 1.62kg/cm
2, rare-earth permanent magnet can magnetize repeatedly, degaussing, and can reach more than 10 years service life.This suspender had both kept the advantage of electromagnetism hoisting sling and ferrite permanent-magnet hoisting sling in sum, had overcome the shortcoming of they existence again, made it become the novel hoisting sling of the update of this two classes magnetic hoisting sling.
Now in conjunction with the accompanying drawings and embodiments the utility model is done specific descriptions:
