Abstract
The utility model belongs to a lifting electromagnet device for preventing materials from falling on port machinery. The lifting electromagnet device comprises an electromagnet control device (1), a movable cable (3), a cable drum (4), an electric wire box I (6) and an electromagnet body (5). The lifting electromagnet device is characterized in that an electric wire box II (8) is arranged on the electromagnet body (5), the P-terminal and the N-terminal of the electric wire box II (8) are connected with the P-terminal and the N-terminal of a cable drum B (9), and the P6-terminal and the N6-terminal of the cable drum B (9) are connected with the right end of a movable cable II (10); the P2-terminal of the electromagnet control device (1) is connected with the left end of a current transformer II (7), and the N2-terminal of the electromagnet control device (1) is connected with the left end of the movable cable II (10); the right end of the current transformer II (7) is connected with the left end of the movable cable II (10); and a current transformer I (2) is connected with the P1-terminal of the electromagnet control device (1) and the left end of the movable cable I (3). The lifting electromagnet device has the advantages that when any one excitation circuit is disconnected, an electromagnet is not disconnected, so that the accident of material falling caused by loss of power is avoided, and the reliability and safety of lifting operation of the port machinery are greatly improved.
Description
Technical field
The utility model belongs to weight-lifting equipment, particularly prevents the lifting electromagnet equipment of material on the machine of a kind of port.
Background technology
The port machine has a lot of occasions all to adopt lifting electromagnet when handling goods at present, because of common tens meters of the height of lifting, is the matter of utmost importance that electromagnet system must be considered so how to prevent material.Mainly there is following hidden danger in the electromagnet system that uses at the port machine both at home and abroad at present: the one, and the slip ring of cable drum comes in contact bad easily or damages, and the energized circuit of electromagnet is disconnected, and causes the electromagnet dead electricity, falls the material accident.The 2nd, when the machine operation of port, cause cable to rub or break easily, make the electromagnet dead electricity, fall the material accident.The 3rd, lead-out terminal bad contact or the damage of electrical controller, and make the electromagnet dead electricity, fall the material accident.The 4th, wiring place in the connection box of electromagnet itself is opened circuit easily and is fallen the material accident.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of can be when any one road energized circuit disconnects, electromagnet does not cut off the power supply, and increases the lifting electromagnet equipment that prevents material on the port machine of port machine lifting job reliability.
The technical scheme that the utility model technical solution problem adopts is: the lifting electromagnet equipment that prevents material on the machine of a kind of port, comprise electromagnet control device, removal cable, cable drum A, electric wire box one and electromagnet ontology, it is characterized in that adorning an electric wire box two at electromagnet ontology, the P of electric wire box two, N end is connected the right-hand member of the P2 of cable drum B, N2 termination removal cable two with P, the N end of cable drum B; The left end of the P5 termination current transformer two of electromagnet control device, the left end of N2 termination removal cable two; The right-hand member of current transformer two connects the left end of removal cable two; Be connected to current transformer one between the P1 end of electromagnet control device and the removal cable left end.
The beneficial effects of the utility model are: this utility model can be when any one road energized circuit disconnects, and the unlikely disconnection of electromagnet can not take place to fall the material accident because of dead electricity, has improved reliability and the safety of port machine lifting job greatly.
