Abstract
The invention discloses an electromagnetic hoisting grapnel, comprising an electromagnetic coil; the electromagnetic coil is sleeved inside a round shell; the external wall of the round shell is provided with three identical external arms; the electromagnetic coil is internally sleeved by a lifting body of magnetic material which can motion upwards and downwards; the lower end of the lifting body is provided with an opening/closing grapnel; the lifting body is internally provided with a hoisting rope; the lower end of the hoisting rope is connected with the opening/closing grapnel; the opening/closing grapnel arm is connected with a supporting rod by a pin shaft; the other end of the supporting rod is fixedly connected with the external arm of the round shell by a pin shaft; the electromagnetic hoisting grapnel of the invention can be matched with cranes of different types such as grapnels on cranes such as workshop traveling cranes, automatic cranes, etc.
Description
Technical field
The present invention relates to a kind of electromagnetic hoisting grab hook of carrying object.
Background technology
Existing hoisting grab hook mostly manpower control opening and closing is realized dress, its inefficiency and effort, but the opening and closing of electromagnetic hoisting grab hook automatic guidance grapple are changeed in the lifting of carrying object.
Summary of the invention
But the object of the present invention is to provide a kind of electromagnetic hoisting grab hook of automatic guidance opening and closing.
The technical solution used in the present invention is as follows:
Electromagnetic hoisting grab hook, it includes magnet coil, described magnet coil is sleeved in the circular shell, described circular shell outer wall is equipped with three identical outer arms, be set with the lifting body of magnetic material that can up-and-down movement in the above-mentioned magnet coil, but the lifting body lower end is equipped with the opening and closing grapple, being provided with a lifting rope lower end in the described lifting body is connected with the opening and closing grapple, connect strut bar by bearing pin on the described opening and closing grapple arm, this strut bar other end is fixedly connected by bearing pin and above-mentioned circular shell outer arm, adopt the electromagnetic hoisting grab hook of said structure, when magnet coil is switched on, form electromagnetic field, electromagnetic field is implemented application force to suit magnetic material lifting body in coil, change the sense of motion of lifting body when the direction of current conversion in the coil simultaneously, grapple opens when the lifting body upward movement, and grapple closes up when moving downward.Electromagnetic hoisting grab hook of the present invention can be equipped with veriform crane, as the workshop row hang, grapple on the crane such as vapour hangs.
The invention will be further described below in conjunction with accompanying drawing:
Description of drawings
Fig. 1 is a structural representation of the present invention;
The specific embodiment
As shown in Figure 1, it includes magnet coil 4 electromagnetic hoisting grab hook, described magnet coil 4 is sleeved in the circular shell 5, described circular shell 5 outer walls are equipped with three identical outer arms, be set with the lifting body 3 of magnetic material that can up-and-down movement in the above-mentioned magnet coil 4, but lifting body 3 lower ends are equipped with opening and closing grapple 1, being provided with a lifting rope 6 lower ends in the described lifting body 3 is connected with opening and closing grapple 1, connect strut bar 2 by bearing pin on the described opening and closing grapple arm, these strut bar 2 other ends are fixedly connected by bearing pin and above-mentioned circular shell 5 outer arms.
