The invention discloses a gear drive type ratchet wheel lifting mechanism which comprises a ratchet wheel wrench component, a screw shaft, a sleeve and a brake. The ratchet wheel wrench component and the brake are arranged on the sleeve. The screw shaft is driven to do lifting motion and is arranged in the sleeve and matched with the sleeve. The brake brakes the ratchet wheel wrench component. Lifting adjustment is carried out on the screw shaft through the ratchet wheel wrench component. The top end of the screw shaft is used for bearing weights. The gear drive type ratchet wheel lifting mechanism is composed of the ratchet wheel wrench component, the screw shaft, the sleeve and the brake; the brake is used for braking a ratchet; it is guaranteed that the ratchet is kept static when a check block moves along the ratchet; the ratchet wheel wrench component is in a gear drive type, transmission tends to be non-polar and is smooth and high in reliability; when a ratchet wheel wrench is operated to swing, the ratchet wheel wrench is more stable and saves more labor. The lifting mechanism is high in reliability, and no slipping phenomenon happens. When the lifting mechanism is operated manually, more time and labor are saved.
