Abstract
The utility model discloses a kind of novel movable iron core type lifting electromagnet, this electromagnet comprises magnetic conduction yoke plate, detachable pole, movable core and magnet exciting coil; Detachable pole, movable core all adopt the activity form of upper and lower vibration, namely in the middle part of magnetic conduction yoke plate, are respectively equipped with middle part magnetic pole box and external magnetic poles box with outside; Movable core is arranged in the magnetic pole box of middle part, in middle part magnetic pole box outer felt around magnet exciting coil, and with without magnetic supporting plate back cover; In detachable pole magnetic pole box mounted externally; Described middle part magnetic pole box is bulge structure.The utility model iron core adopts bulge shape, and after electromagnet coiling, bulge iron core can provide a strong point to electromagnetic wire, in case the lax swollen line of electromagnetic wire, the situation that cannot be close to rectangle iron core surface occur.And after infusion epoxy resin, electromagnetic wire is effectively concentrated and is close to bulge iron core, the electromagnetic wire motion caused owing to expanding with heat and contract with cold can not be there is, solve the problem of terminals bearing fracture.
Description
One, technical field
The utility model belongs to lifting electromagnet technical field, is specifically related to a kind of novel movable iron core type lifting electromagnet.
Two, background technology
In recent years along with the development in the field such as iron and steel, harbour, the kind of on-the-spot absorbate material got more and more, and absorbate material surface configuration varies.For solving the problem of field working conditions harshness, create movable iron core type lifting electromagnet, solve problem dramatically, but still there are some problems in common stir yourself iron core type lifting electromagnet: electromagnet is carrying out in winding process, due to the style characteristic of rectangle iron core, the lax swollen line of electromagnetic wire can be caused, the situation on iron core surface cannot be close to.After infusion epoxy resin, the electromagnetic wire motion caused owing to expanding with heat and contract with cold, very easily causes terminals bearing to be ruptured, so that electromagnet is scrapped.In addition, this swollen line situation can cause there is space between electromagnetic wire, and namely also not close is affixed between the lines, but there is air, has a strong impact on heat conduction and the heat radiation of electromagnetic wire like this, and wastes pouring material.
Three, summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, is skillfully constructed, effectively can overcomes the novel movable iron core type lifting electromagnet of the many deficiencies of existing movable iron core type lifting electromagnet.
For achieving the above object, the technical solution adopted in the utility model is: this electromagnet comprises magnetic conduction yoke plate, detachable pole, movable core and magnet exciting coil; Detachable pole, movable core all adopt the activity form of upper and lower vibration, namely in the middle part of magnetic conduction yoke plate, are respectively equipped with middle part magnetic pole box and external magnetic poles box with outside; Movable core is arranged in the magnetic pole box of middle part, in middle part magnetic pole box outer felt around magnet exciting coil, and with without magnetic supporting plate back cover; In detachable pole magnetic pole box mounted externally; Be characterized in: described middle part magnetic pole box is bulge structure.
The utility model iron core adopts bulge shape, and protection inner coil configuration, effectively solves some row problems such as the electromagnetic wire caused because of swollen line breaks.After electromagnet coiling, bulge iron core can provide a strong point to electromagnetic wire, in case the lax swollen line of electromagnetic wire, cannot be close to rectangle iron core surface situation occur.And after infusion epoxy resin, electromagnetic wire is effectively concentrated and is close to bulge iron core, the electromagnetic wire motion caused owing to expanding with heat and contract with cold can not be there is, solve the problem of terminals bearing fracture.Further, due to electromagnetic wire compact conformation, thermal conductivity and thermal diffusivity obviously strengthen, and also save pouring material simultaneously.
Four, accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is upward view of the present utility model.
Five, detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model comprises magnetic conduction yoke plate 2, detachable pole 3, movable core 4, magnet exciting coil 6, hanger 7 and forms without magnetic supporting plate 8.Hanger 7 is welded on magnetic conduction yoke plate 2, to be connected to carry out hoisting operation by chain sling with crane.Middle part magnetic pole box 1 and external magnetic poles box 5 is welded with, in the outer felt of middle part magnetic pole box 1 around magnet exciting coil 6, and with without magnetic supporting plate 8 back cover in the middle part of magnetic conduction yoke plate 2 and outside.Movable core 4 and detachable pole 3 are loaded in middle part magnetic pole box 1 and external magnetic poles box 5 respectively, and detachable pole 3 and movable core 4 all can upper and lower vibrations, meet most operating mode onsite application.Described middle part magnetic pole box 1 is bulge structure.Without the lower end of magnetic supporting plate 8 lower end a little more than detachable pole 3, just can play positive stop effect without magnetic supporting plate 8 like this, size discrepant ironware can be stopped when being picked up, prevent detachable pole 3 upwards excess shrinkage, cause clamping to occur phenomenon of rupture, effectively extend the service life of detachable pole.
The utility model adopts said structure that the scope of application of lifting electromagnet is widened further greatly, can safe ready practicality to various complicated harsh work condition environment.
