Abstract
The utility model discloses an electromagnet which is provided with a movable magnetic pole and suitable for attracting objects in irregular shapes. The electromagnet comprises a frame including an upper yoke plate, a lateral yoke plate and a bottom plate, a solenoid coil positioned in the frame, and a magnetic pole in middle of the solenoid coil; an opening is formed in the middle of the upper yoke plate; the upper end of the magnetic pole passes through the opening of the upper yoke plate; an expansion box is arranged on the upper surface of the magnetic pole; the magnetic pole consists of a plurality of small magnetic poles parallel to each other; a connecting rod is arranged at the upper end of each small magnetic pole; the connecting rods pass through through-holes on the expansion box; and limiting nuts are arranged at the outer ends of the connecting rods. The utility model has the advantages that when the objects in the irregular shapes are attracted, retractable magnetic poles can be automatically arranged according to the surfaces of the objects, and extended downwards or retracted, so that the contact surface area of the magnetic pole and the objects. Therefore, the electromagnet attracts the objects with the irregular shapes more stably, and the hoisting capacity is high. Particularly, the utility model is suitable for attracting bundles of steel material and steel pipes, castings in irregular shapes, and the like.
Description
One, technical field
The utility model relates to a kind of lifting electromagnet, particularly is suitable for the lifting electromagnet with detachable pole of lifting irregular-shaped objects.
Two, background technology
It is fixing circular or square that lifting electromagnet mostly is, and is made up of magnetic conduction yoke plate, magnet coil, consequent pole and insulating material etc.The magnetic pole of general lifting electromagnet is all fixed, and its bottom surface is the plane, when the erose object of lifting, because hanging object can't contact below the lifting electromagnet magnetic pole fully, the lifting effect is had a significant impact.
Three, summary of the invention
The purpose of this utility model provides a kind of lifting electromagnet with detachable pole, and its magnetic pole can be more suitable in the lifting to irregular-shaped objects in when work telescopic variation.The technical solution adopted in the utility model is; Lifting electromagnet with detachable pole comprises the framework that is made of upper magnet yoke plate, side yoke plate and base plate, be positioned at the magnet coil of framework and the magnetic pole in the middle of the coil, opening is arranged in the middle of the upper magnet yoke plate, the opening of upper magnet yoke plate is passed in the magnetic pole upper end, be provided with expansion box on magnetic pole, magnetic pole is made of a plurality of little magnetic poles that are parallel to each other, and there is pipe link each little magnetic pole upper end, pipe link passes the open-work on the expansion box, in the outer end of pipe link stop nut is arranged.
Magnetic pole of the present utility model is rearranged by a plurality of telescopic little magnetic pole rules, can freely stretch at upper magnet yoke plate central closing, and during work, magnetic pole can stretch out from the bottom of electromagnet, in the expansion box on the electromagnet top of also can withdrawing under pressure.When the erose object of lifting, the convex surface of the hanging object that contacts with magnetic pole can compress the magnetic pole retraction expansion box that makes progress, concave surface can make electromagnet extend into concave bottom under the effect of gravity and spring force, and the contact surface of electromagnet pole and object is increased greatly, and the magnetic circuit closure is tighter.
The utility model is designed to be with the telescopic detachable pole of elastic force with electromagnet pole, when the erose object of lifting, telescopic magnetic pole can be arranged automatically with body surface, the mating surfaces that strengthens magnetic pole and object is long-pending, make electromagnet more stable when the lifting irregularly shaped object, hoisting capacity is bigger, is particularly suitable for the bundled steel of lifting, steel pipe and foundry goods in irregular shape etc.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
Lifting electromagnet with detachable pole comprises the framework that upper magnet yoke plate 1, side yoke plate 2 and base plate 6 constitute, magnet coil 3 in the framework and the magnetic pole 7 in the middle of the magnet coil have cooling media 4 in magnet coil 3 peripheries, at magnet coil 3 and upper magnet yoke plate with insulating barrier 5 is arranged at the end.Detachable pole 7 is a rectangle, the bottom chamfering, and there are M20 * 30 screws at the center, upper end.Magnetic pole 7 is the detachable poles that are made of a plurality of regular arrangements of little magnetic pole that are parallel to each other, the length of whole detachable pole 7, and the upper end is not less than above the upper magnet yoke plate 1 in the time of stretching out base plate 6 to end position in the lower end.On upper magnet yoke plate 1, be welded with hanger 8, be used to connect chain sling and carry out hoisting operation.On magnetic pole 7, be provided with expansion box 9, Φ 21 holes are opened at the center of expansion box 9 corresponding each little magnetic pole, pipe link 10 can be passed in the hole and be connected with magnetic pole 7, pipe link 10 is the rod iron of double headed roller M20 * 50 screw threads, stretch into from the perforate of expansion box and to pass spring 11 and couple together by screw thread and magnetic pole 7, the upper end has stop nut to be stuck in expansion box 9 outsides, and magnetic pole 7 can not broken away from whole electromagnet, can change the length that magnetic pole stretches out by adjustment nut.Connect auxiliary connect spring 11 on magnetic pole 7, spring 11 upper ends are connected on the expansion box 9, and spring 11 can be given magnetic pole, 7 one downward power, and magnetic pole 7 can not put down because of friction force.Because magnetic pole 7 activities are set up magnet coil sheath 12 between magnet coil 3 and magnetic pole 7, magnet coil 3 makes magnetic pole 7 that magnet coil is damaged on magnet coil sheath 12.
