JK type mine elevator
Product features, main applications and scope of application:JK series elevators are in accordance with the safety production industry standard of the People's Republic of China AQ 1035-2007 safety inspection specification of single-rope winding type Mine elevators for coal mines, GB/T20961-2007 single-rope winding type Mine elevators and enterprise standards q/HNQM003-2016 product designed and manufactured by "single-rope winding mine elevator.
It is applicable to the ground of Coal Mine, metal mine and non-metal mine or the inclined roadway and shaft under the well for lifting materials and personnel.
Working principle:When starting the main motor, the rotor of the motor transmits the power to the high-speed axis of the reducer through the elastic coupling, and then transmits the power to the principal axis device through the driving and slowing down of the reducer through the gear coupling, if the steering of the motor is constantly changed, the reel can be twined or the steel wire rope can be loosened, so that the lifting container can make the periodic movement of up and down in the wellbore.
Representation of product model:The model representation method of elevator should accord with the provisions of MT/T 154.8-1996 "formation method of model of coal mine machinery products.
The diameter of the reel is 2 m, and the width is 1.8 m. The product model of the single reel and single rope winding type mine elevator which adopts non-explosion resistance speed control is: JK-2 × 1.8;
The diameter of the reel is 3.5 m, and the width is 2.8 m. The product model of the single reel and single rope winding type mine elevator adopting non-explosion-proof frequency conversion speed control is: JK-3.5 × P;
