Abstract
The utility model relates to an electrohydraulic controlled automatic furnace door opening/closing device, comprising a motor, a hydraulic pressure system and an opening/closing mechanism, wherein the hydraulic pressure system is connected on the motor and comprises an oil cylinder and a piston rod, the opening/closing mechanism comprises a rotating pair and an opening/closing arm, the top part of the piston rod is movably connected with the rotating pair which is connected with one end of the opening/closing arm, and the other end of the opening/closing arm is connected with a furnace door. The furnace door is driven to be out of a furnace opening in the vertical direction by the hydraulic pressure system through the opening/closing arm, the furnace door can be fully opened by rotating the furnace door to be separated from the furnace opening in the horizontal direction through the rotating pair, the electrohydraulic controlled automatic furnace door opening/closing device is simple in structure and is stable when opening and closing the furnace door, the locking phenomenon caused by the existing structure for opening a door is effectively avoided, and the electrohydraulic controlled automatic furnace door opening/closing device is safe and reliable in using, is convenient in maintenance and is low in using cost.
Description
Technical field
The utility model relates to a kind of fire door recloser of electrichydraulic control, is used for the automatic device that opens and closes of fire door of single crystal growing furnace, polycrystalline furnace equal vacuum stove and pressure vessel.
Background technology
As everyone knows, single crystal growing furnace, polycrystalline furnace equal vacuum stove all need to open fire door through headstock gear in charging, when getting material.Existing door open and close device generally adopts the form of feed screw nut or linkage; The defective of the door open and close device of such form is; When the furnace chamber internal pressure is excessive, can produce mechanical locking phenomenon, make fire door to open, thereby cause the furnace chamber inner components to be damaged; Even blast, therefore there is very big potential safety hazard.
Summary of the invention
Open and close and adopt feed screw nut or linkage form to be easy to generate locking in order to overcome in the prior art fire door, cause the problem of security incident, the fire door recloser of a kind of anti-lock, safe and reliable, simple and reasonable electrichydraulic control is provided.
The technical scheme of the utility model is: a kind of fire door recloser of electrichydraulic control; Its technical characterstic is to comprise motor, hydraulic system, switching mechanism, connects hydraulic system on the motor, and hydraulic system comprises oil cylinder, piston rod; Switching mechanism comprises revolute, switch arm; The top movable of said piston rod connects revolute, connects an end of switch arm on the revolute, and the other end of switch arm connects fire door.The Electric Machine Control hydraulic system rises by oil cylinder piston bar driven rotary is secondary, and revolute drives fire door through switch arm and rises and leave fire door, moves on the fire door horizontal direction the most at last and staggers with fire door and realize opening fully of fire door; Otherwise fire door is closed.
Connect sliding bar on the said piston rod, the top of sliding bar connects revolute.Realize and the apical grafting of revolute that by sliding bar sliding bar is convenient to change, safeguard, the piston rod long service life is practiced thrift use cost.
Said piston rod or sliding bar are with fairlead outward, and fairlead is on the support of frame.Fairlead helps guaranteeing that the up-down of piston rod or sliding bar is stable, safe in utilization, stable.
Said revolute is bearing or copper sheathing, and piston rod or sliding bar top are provided with the spacer pin of spacing revolute.The movable rotation of revolute drives fire door through switch arm and rotates in 360 ° of scopes in the horizontal direction, is convenient to fire door and is vertically staggering with fire door on the horizontal direction; After oven door opening puts in place, limit fixedly fire door of revolute by spacer pin, prevent loosening accident, guarantee production safety.
The utility model adopts hydraulic system to drive fire door vertical direction disengaging fire door through switch arm; Simultaneously make the fire door horizontal direction fire door that staggers realize opening fully of fire door through the revolute rotation, it is simple in structure, and fire door opens and closes stable; The locking imagination of effectively avoiding existing opening structure to cause; Safe in utilization, reliable, easy to maintenance, use cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: frame 1, motor 2, oil cylinder 3, piston rod 4, sliding bar 5, fairlead 6, support 7, revolute 8, spacer pin 9, switch arm 10.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Figure 1, a kind of fire door recloser of electrichydraulic control comprises motor 2, oil cylinder 3, piston rod 4, sliding bar 5, fairlead 6, support 7, revolute 8, spacer pin 9 and switch arm 10.Motor 2 connections are supported in the oil cylinder 3 on the frame 1, and piston rod 4 tops of oil cylinder 3 connect sliding bar 5 bottoms, are socketed with fairlead 6 on the sliding bar 5; Fairlead 6 is connected on the support 7 that is fixed on the frame 1; Sliding bar 5 tops connect revolute 8, and revolute 8 is a steel bushing, the relative rotation through between spacer pin 9 spacing revolutes and sliding bar of revolute 8 and sliding bar 5; Connect switch arm 10 1 ends on the revolute 8, switch arm 10 other end levels connect the fire door of crystal oven.
During this device work; Motor is just changeing moves up in-oil cylinder piston rod under the effect of hydraulic pressure difference; Slide in fairlead thereby drive sliding bar, the revolute that the sliding bar top is connected drives the stove door switch arm and moves up, and fire door moves up and breaks away from fire door at vertical direction; Promote fire door then and be the axle center and horizontally rotate and make fire door and the fire door realization oven door opening that on vertical horizontal direction, staggers, can feed in raw material, get material work with the revolute.Otherwise, when closing fire door, promote fire door and rotate to the furnace chamber top, the motor counter-rotating, piston rod drive sliding bar to lower slider, closes fire door in fairlead.
