Abstract
The utility model discloses a novel electromagnetic crane with independent reversely demagnetizing coils. The electromagnetic crane is formed by an iron core wound coil in a magnetic frame. The utility model is characterized in that the coil adopts the double-coil structure of a demagnetizing coil and a magnetizing coil, wherein, the demagnetizing coil is arranged in the inner side of the magnetizing coils, thereby reducing production costs. The utility model is simple in structure and reasonable in design. The demagnetizing and magnetizing coils are independent, which avoids the phenomenon of drawing arcs caused when the current in the great is on or off. Therefore, the non-contact control of the switch is achieved, the failure-free operation time is prolonged and the production efficiency of customers is improved.
Description
One, technical field
The utility model belongs to electromagnetic type weight-lifting equipment technical field, is specifically related to a kind of electromagnet that is used for the ferromagnetic material handling and hangs.
Two, background technology
The electromagnetic lifter application scenario is wider, as stevedoring, metallurgy industry carrying steel etc.Under normal conditions, electromagnetic lifter needs reverse degaussing in the handling process.But existing electromagnetic lifter adopts disc type or rectangle single coil structure more, and needing not only influences production efficiency with outage or oppositely degaussing operation unloading, and influences the service life of itself and control convenience thereof.Because the limitation of existing electromagnetic lifter equipment, if want to add the degaussing function, its control loop can only adopt direct current or AC contactor, and continuous current circuit is when reverse degaussing, necessary series resistance, this control loop contact of its contactless switch in use has electric arc to produce always, is therefore seriously reduced the non-failure operation time of its electromagnetic lifter, has influenced the service life of its electromagnetic lifter greatly.
Three, summary of the invention
The purpose of this utility model provides a kind of independent oppositely electromagnetic lifter of degaussing coil that has, and makes it can realize noncontacting switch control, the non-failure operation time of fundamentally improving electromagnetic lifter equipment, and can realize intelligent control.
The utility model is that iron core winding around in the framework constitutes by magnetic.Be characterized in that described coil adopts the two coil configuration that is made of degaussing coil and excitation coil.Degaussing coil is positioned at the inboard of excitation coil, can reduce manufacturing cost.
The utility model is simple in structure, and is reasonable in design.Excitation coil and degaussing coil are independent separately, produce the deficiency of arcing phenomenon when having solved large-scale inductive devices energising with cutout, thereby can make its control convenience realize noncontacting switch control.By evidence, the two coil configuration that adopts degaussing coil and excitation coil to constitute has improved the non-failure operation time of the utility model electromagnetic lifter, thereby has improved user's production efficiency.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
Magnetic of the present utility model is that framework is made of iron plate 1,2 and iron core 4, coaming plate 7, end backplate 8.Iron plate 2 is provided with wire connection cavity 3, and the lead and the coil that are used for control loop join.Do the surface insulation processing earlier with iron plate 1,2 and iron core 4 usefulness bolt or weld togethers, and with iron core 4; Carry out the coiling of degaussing coil 5 and excitation coil 6 then.Degaussing coil 5 and excitation coil 6 can turn to two complete independent structures, also can turn to the form that is connected in series.After coiling is finished, all do insulation and handle; Again coaming plate 7 is welded on the iron plate 2, after doing insulation and handling, again end backplate 8 is welded, inwardly irritate epoxy resin from wire connection cavity 3.End backplate 8 is selected the non-magnetic rustproof steel plate for use.Generally speaking, the density of current of degaussing coil 5 be excitation coil 6 2-4 doubly.Density of current as 1400 type excitation coils is elected 1A/mm as
2, degaussing coil is generally elected 3A/mm as
