Abstract
The utility model discloses an electromagnetic type operation execution mechanism, which belongs to the technical field of operation execution elements and comprises an electromagnetic coil and a casing matched with and fixing the electromagnetic coil. The electromagnetic coil is arranged and fixed in the casing. An installation hole is arranged in the center of the electromagnetic coil and a telescopic iron core capable of executing operations telescopically is arranged in the installation hole. The installation positions of the telescopic iron core are as follows: when the electromagnetic coil is powered off, the head portion of the telescopic iron core extends out of the casing, and when the electromagnetic coil is powered on, the telescopic iron core withdraws into the casing for being absorbed by a magnetic field. The operating principle is that when the electromagnetic coil is powered on, the magnetic field is generated in the center of the electromagnetic coil, and the telescopic iron core made of ferromagnetic materials is absorbed by a certain distance by generated absorption and driven to move. When the electromagnetic coil is powered off, the magnetic field disappears and the telescopic iron core restores. The electromagnetic type operation execution mechanism has the advantages of simple structure, good generality and quick operation.
Description
Technical field
The utility model relates to action power element technical field, specifically is a kind of electromagnetic type action actuating mechanism.Be applicable to the occasion of multiple palpus installation action power element.Be specially adapted to the broken belt arresting agency.
Background technology
Mechanical electronic hydraulic integrated formula broken belt is arrested the action actuating mechanism of device, is by the hydraulic efficiency pressure system effect, carries out by oil cylinder and arrests action, and the intermediate link hydraulic efficiency pressure system has increased cost; It is poor that common mechanical type broken belt is arrested the conformability of device action.
Summary of the invention
For solving the deficiency of above-mentioned prior art, the utility model provides a kind of electromagnetic type action actuating mechanism, can make broken belt arrest device make unified, brake the belt action rapidly, realize that broken belt is arrested device behind the conveyor belt breakage reliably to arrest.
The utility model is realized with following technical scheme: a kind of electromagnetic type action actuating mechanism, comprise magnet coil, and cooperate the shell of Motionless electromagnetic coil with magnet coil; Magnet coil is fixed in the shell, in the central authorities of magnet coil mounting hole is arranged, and installs one in the mounting hole and can stretch in the hole and carry out the flexible iron core that moves; The installation site of described flexible iron core is: when the magnet coil no power, the head of flexible iron core stretches out outside the shell, and when magnet coil was switched on, flexible iron core was subjected in the magnetic field suction withdrawal shell.
Principle of work: behind the logical upward power supply of coil, produce magnetic field at hub of a spool, the flexible iron core generation suction to ferromagnetic material promotes the iron core action, and iron core suction certain distance, after dead electricity, magnetic field disappears, and iron core resets.
The beneficial effects of the utility model are: simple in structure, commonality is good, is swift in motion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, flexible iron core; 2, magnet coil; 3, explosion-resistant enclosure.
The specific embodiment
As shown in drawings, the electromagnetic type action actuating mechanism has a magnet coil 2, cooperates the shell 3 that is used for fixing magnet coil with magnet coil 2; Magnet coil 2 is fixed in the shell 3, in the central authorities of magnet coil 2 mounting hole is arranged, and installs one in the mounting hole and can stretch in the hole and carry out the flexible iron core 1 that moves.The installation site of flexible iron core 1 is: when magnet coil 2 no powers, the head of flexible iron core 1 stretches out outside the shell 3, and when magnet coil 2 energisings, flexible iron core 1 is subjected in the magnetic field suction withdrawal shell 3.
Present embodiment is used in it in broken belt arresting agency of belt conveyer of down-hole, and shell 3 is an explosion-resistant enclosure.Power supply adopts colliery general-duty 127V power supply, and flexible iron core was withdrawn opening time less than 0.5 second.Be fixed on the catching device, can will stretch iron core withdrawal after electric, broken belt is arrested device and by elastic force brake control lever is thrown away, the braking belt.Electromagnet dead electricity back valve core can stretch out automatically.
