Rewinding elevator traction machine with built-in traction wheel

The utility model discloses a compound winding elevator traction machine with a built-in traction wheel, which belongs to the technical field of elevator traction machines and comprises a mounting frame, a reduction gearbox is fixedly connected onto the mounting frame, an output shaft is rotatably connected into the reduction gearbox, and a locking gear is coaxially and fixedly connected to one end, far away from the output shaft, of a traction wheel body. A brake block is fixedly connected to the bottom of the hydraulic rod, a piston cylinder is fixedly connected to the reduction gearbox, a piston rod is slidably connected into the piston cylinder, and a cleaning brush used for cleaning the traction wheel body is fixedly connected to the piston rod. When the brake block ascends and descends, the piston rod can be driven by the connecting rod to axially slide back and forth, and the cleaning brush on the piston rod can clean the traction wheel body when the piston rod axially slides back and forth, so that su
