Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0036] Such as figure 1 As shown, a traction device with safety gear includes a traction machine 1 arranged on the installation platform 7 at the top of the elevator shaft. The traction machine uses a servo motor to precisely control its speed. The traction machine consists of The power source that drives the car up and down. A traction sheave 4 is coaxially connected to the output shaft of the traction machine, and a traction rope 41 is wound around the traction sheave. One end of the traction rope is connected to the car 8 after bypassing the diverting pulley, and the other end of the traction rope One end bypasses the diverting pulley and is connected to the counterweight 9, and the traction wheel and the traction rope together constitute an action actuator that drives the car to go up and down. When the traction machine outputs torque to ...
