Also comprise the limit switch for sending the automatic stop signal of emergency actuation to main gas control cabinet being arranged at converter secure location side, limit switch is connected by gas circuit with described main gas control cabinet.
The beneficial effects of the utility model are: the utility model can the full automatic converter inclining that makes be to secure location in the state of accident, and its security is higher; In the utility model, pneumatic motor is directly connected with the power intake of pneumatic clutch by step-down gear, and structure is more rationally compact, and volume is little, and structural strength is better, be suitable for being used in vibration larger fascinate on machine; The utility model only adopts compressed gas source to be propulsion source, and without any need for power supply during operation, as long as ensure source of the gas, accidental operation just can carry out, and cost is lower, and reliability is higher; The utility model is except manually stopping emergency actuation, limit switch also can be utilized automatically to stop emergency actuation, and when there is major accident, as long as operator press the button startup, accidental operation just can withdraw scene rapidly, by the time need not operate end, emergency actuation can stop automatically.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings: 1-long-distance control cabinet; The main gas control cabinet of 2-; 3-pneumatic motor; 4-step-down gear; 5-pneumatic clutch; 6-Pneumoelectric dual control stopper; 7-step-down gear; The main gas circuit of 8-; 9-controls gas circuit; 10-limit switch; 11-main drive motor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of complete pneumatic accident actuating device of converter inclining machine, comprise pneumatic motor 3, pneumatic clutch 5, a step-down gear 7, main gas control cabinet 2, step-down gear 4, Pneumoelectric dual control stopper 6 and long-distance control cabinet 1, the clutch end of pneumatic motor 3 is connected with the power intake of step-down gear 4, the clutch end of step-down gear 4 is connected with the power intake of pneumatic clutch 5, the clutch end of pneumatic clutch 5 inputs high speed shaft with one end of a reducing motor and is connected, Pneumoelectric dual control stopper 6 is connected between the other end input high speed shaft of a step-down gear 7 and main drive motor 11, main gas control cabinet 2 is connected with pneumatic motor 3 by main gas circuit 8, main gas control cabinet 2 controls gas circuit 9 by two and is connected with pneumatic clutch 5 and Pneumoelectric dual control stopper 6, long-distance control cabinet 1 is connected by gas circuit with main gas control cabinet 2.
When converter normally works, the high speed shaft of a step-down gear 7 drives normal work by main drive motor 11, and whole emergency actuation source of the gas cuts off, and does not allow emergency actuation to operate, monitors bleed pressure in real time, for emergency actuation prepares; When there is power outage or main drive fault, the conducting of emergency actuation source of the gas, main gas control cabinet 2 controls pneumatic clutch 5 by main gas circuit 8 and first closes, then main gas control cabinet 2 controls gas circuit 9 by one and controls pneumatic motor 3 action, rear main gas control cabinet 2 controls gas circuit 9 by another and controls Pneumoelectric dual control stopper 6 action, pneumatic motor 3 drives the input high speed shaft of a step-down gear 4 to rotate by step-down gear 4, clutch coupling, drives converter body reset or forward secure location to; When converter body reset or after forwarding secure location to, emergency actuation stops, and first close Pneumoelectric dual control stopper 6, then pneumatic motor 3 stops action, and last pneumatic clutch 5 is thrown off.
The utility model is made up of machinery and pneumatic mechanism, only adopts compressed gas source to be propulsion source, and without any need for power supply during operation, as long as ensure source of the gas, accidental operation just can carry out.Single compressed gas source is that propulsion source makes emergency actuation safer, and single power source preparation is more prone to, easy to implement, avoids the increase of complex operation that multi power source brings and production cost.In addition, pneumatically operated equipment belongs to pure physical construction, and in STEELMAKING PRODUCTION environment, reliability is higher than electric installation.
Long-distance control cabinet 1, for carrying out remote monitoring and operation, is convenient to open emergency actuation in time if desired.When production power-off or main drive fault, operating personnel presses the start button on control panel, realizes emergency actuation and runs; When needs stop emergency actuation, turn start button makes it reset; When there are urgent abnormal conditions in emergency actuation operational process, take emergency stop switch and can stop emergency actuation operation, system reset.
The utility model also comprises the limit switch 10 for sending the automatic stop signal of emergency actuation to main gas control cabinet 2 being arranged at converter secure location side, and limit switch 10 is connected by gas circuit with main gas control cabinet 2.When converter turns to secure location, it touches limit switch 10, limit switch 10 signal that will put in place sends main gas control cabinet 2 to, main gas control cabinet 2 stops emergency actuation automatically, and like this when there is major accident, as long as operator press the button startup, accidental operation just can withdraw scene rapidly, by the time end need not be operated, emergency actuation can stop automatically, safer, effectively prevent loss of life and personal injury.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
