The invention discloses a hydraulic stove changing switch, and relates to mechanical field. The hydraulic stove changing switch comprises a rack, wherein two groups of hydraulic devices and four groups of furnace body cable connecting copper bars are arranged in the rack; each hydraulic device comprises two hydraulic cylinders which are coaxially symmetrical up and down; plunger pistons are arranged on the hydraulic cylinders; universal ball heads are arranged on the plunger pistons; a connecting plate is arranged under the corresponding plunger pistons; an insulating plate with a thickness being 3-5cm is arranged below the corresponding connecting plate; a conductive plate is arranged below the corresponding insulating plate; each conductive plate is in contact and is electrically connected to the corresponding furnace body cable connecting copper bars; a spring is arranged on the corresponding connecting plate at the upper end; and the upward side of each spring is in elastic type contact with the rack through dual regulation of the corresponding spring and the corresponding hydraulic cylinders. According to the hydraulic stove changing switch, the current situation that poor contact is easily caused by a conventional direct-connecting type is changed.
Description
Technical field
The present invention relates to mechanical field, be specifically related to a kind of hydraulic pressure and change stove switch.
Background technology
The body of heater switching switch of medium frequency induction melting furnace is to change stove reliability to improve working furnace switching efficiency, improving and reduce labor strength. What " one electricity double-furnace-body double " formula induction melting furnace comparatively commonly used is that manual type changes stove switch and electrodynamic type changes stove switch, and changing stove switch is be connected in a certain in electric capacity/power cabinet and two bodies of heater. For " one electricity double-furnace-body double " formula induction melting furnace, when body of heater selected by electric smelting time, another body of heater must by safe power-off, and enter in body of heater cooling and maintaining, for instance, artificial fettling or new furnace lining of tiing a knot in time. The operating current of high-power induction melting furnace is very big, and what change that stove switch passes through is exactly the total current of induction melting furnace, and therefore in the short range around switch, common iron all can sensed generate heat. Manual type changes stove switch, there is simple in construction, reliability high, but when changing stove every time, then need to change furnace operating work, at A, B two, station dismounts movable connection copper bar, often changing a stove, an actuator needs within five minutes, just to complete to change furnaceman at least and makees; Electrodynamic type changes stove switch can save manual physical's operation alive, changes stove action soon, but construction of switch is complicated, bulky, and after life-time service, fault rate is higher, and mechanical performance is poor, and traditional automatic hydraulic changes stove and switchs the problem that there is also loose contact.
Summary of the invention
