A tooth sleeve type rope adjustment clutch for a deep well heavy load elevator comprises a main shaft outer tooth sleeve, a movable inner-outer tooth sleeve, a movable winding drum inner tooth sleeve, rope adjustment oil cylinders, a shifting ring and clamping plates. The main shaft outer tooth sleeve is fixedly connected to a main shaft through the two clamping plates. The movable winding drum inner tooth sleeve is connected to a movable winding drum. The main shaft outer tooth sleeve is sleeved with the movable inner-outer tooth sleeve in a sliding manner. Inner teeth of the movable inner-outer tooth sleeve can be engaged with outer teeth of the main shaft outer tooth sleeve. Outer teeth of the movable inner-outer tooth sleeve can be engaged with inner teeth of the movable winding drum inner tooth sleeve. The end of the movable inner-outer tooth sleeve is fixedly sleeved with the shifting ring. An inner hole of the shifting ring is connected with plungers of the rope adjustment oil cylinders so that the movable inner-outer tooth sleeve can be driven by the rope adjustment oil cylinders to slide on the main shaft outer tooth sleeve back and forth so as to achieve engagement or disengagement between the outer teeth of the movable inner-outer tooth sleeve and the inner teeth of the movable winding drum inner tooth sleeve. The tooth sleeve type rope adjustment clutch is compact in structure, high in rope adjustment precision, free of structural limit to a main shaft of the elevator, capable of transmitting large torque, good in safety and stability and capable of meeting the requirement of the large heavy-load elevator.
