Technical field
This utility model relates to mechanical field, is specifically related to a kind of hydraulic pressure and changes stove switch.
Background technology
The body of heater switching switch of medium frequency induction melting furnace is to improve working furnace switching efficiency, carrying
Height changes stove reliability and reduces labor strength." an electricity double-furnace-body double " formula induction melting furnace is relatively
Being that manual type changes stove switch and electrodynamic type changes stove switch for commonly use, changing stove switch is by electricity
A certain in appearance/power cabinet and two bodies of heater is connected.For " an electricity double-furnace-body double " formula sense
For answering smelting furnace, when body of heater selected by electric smelting time, another body of heater must be pacified
Full power-off, and enter in body of heater cooling and maintaining, such as, artificial fettling in time or
Tie a knot new furnace lining.The operating current of high-power induction melting furnace is very big, changes stove switch and just passes through
It is the total current of induction melting furnace, therefore in the short range around switch, common iron
Will sensed heating.Manual type changes stove switch, has simple in construction, reliability high,
But when changing stove every time, then need to change furnace operating work and dismount movable connection at A, B two on station
Copper bar, often changes a stove, and an actuator needs within five minutes, just can complete to change stove at least
Work；Electrodynamic type changes stove switch can save manual physical's operation alive, changes stove action soon, but switch
Structure is complicated, bulky, and after life-time service, fault rate is higher, and mechanical performance is poor, tradition
Automatic hydraulic change stove switch there is also loose contact problem.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic pressure to change stove switch, to solve prior art
In the above-mentioned multinomial defect that causes.
A kind of hydraulic pressure changes stove switch, including frame, be provided with in described frame two groups of hydraulic means and
Four groups of body of heater cables connect copper bar, and described hydraulic means includes the hydraulic pressure of about two coaxial-symmetricals
Cylinder, described hydraulic cylinder is provided with plunger, and described plunger is provided with universal ball end, described multi-directional ball
Head has connecting plate, is provided with insulation board below described connecting plate, and the thickness of described insulation board is
3-5cm, is provided with conductive plate below described insulation board, described conductive plate is connected copper with body of heater cable
Row's contact electrical connection, the connecting plate of described upper end is provided with spring, above described spring and frame
Connect.
Preferably, described insulation board is epoxy resin board.
Preferably, the material of described hydraulic cylinder is degaussing stainless steel material.
Preferably, the upper end hydraulic cylinder in described hydraulic means is movable, described hydraulic pressure
Lower end hydraulic cylinder in device is fixed.
Preferably, in described two groups of hydraulic means, the conductive plate of upper end is connected copper bar with body of heater cable
Side can only be had under duty to be in the state of contact electrical connection.
The utility model has the advantage of: rational in infrastructure, easy to use, by spring and hydraulic pressure
The dual regulation and control of cylinder realize spring-style contacts, and what change tradition was direct-connected easily causes loose contact
Present situation, meanwhile, in two groups of hydraulic means, the conductive plate of upper end is connected copper bar work with body of heater cable
Making the state that side can only be had under state to be in contact electrical connection, one group of hydraulic means is in circuit
During connected state, plunger of another group hydraulic cylinder drives and moves in component below, make conductive plate with
Body of heater cable connects copper bar and is in released state, controls electric furnace running power, reduces voltage and bears
There is not the situation of power-off.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of hydraulic pressure described in the utility model changes stove switch.
Fig. 2 is universal ball end and the spring that a kind of hydraulic pressure described in the utility model changes stove switch
Part enlarged diagram.
Wherein: 1 frame, 2 hydraulic means, 3 body of heater cables connect copper bar, 4 hydraulic pressure
Cylinder, 5 plungers, 6 universal ball ends, 7 connecting plates, 8 insulation boards, 9 conductive plates,
10 springs.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, to reach purpose easy with effect
In clear understanding, below in conjunction with detailed description of the invention, this utility model is expanded on further.
As depicted in figs. 1 and 2, a kind of hydraulic pressure changes stove switch, including frame 1, described frame
It is provided with two groups of hydraulic means 2 in 1 and four groups of body of heater cables connect copper bar 3, described hydraulic means
2 hydraulic cylinders 4 including about two coaxial-symmetricals, described hydraulic cylinder 4 is provided with plunger 5,
Described plunger 5 is provided with universal ball end 6, and described universal ball end 6 has connecting plate 7, institute
Stating and be provided with insulation board 8 below connecting plate 7, the thickness of described insulation board 8 is 3-5cm, described
Being provided with conductive plate 9 below insulation board 8, described conductive plate 9 is connected copper bar 3 with body of heater cable and connects
Get an electric shock connect, the connecting plate 7 of described upper end is provided with spring 10, above described spring 10 with
