The invention discloses a winch for a core drill. The winch for the core drill comprises a dual gear connected with an output gear in a hydromatic brake speed increasing box. The dual gear is installed at the end of a winch shaft. The winch shaft is installed in a coiling block. A braking band-type brake is installed on a brake pulley at the left end of the coiling block. The outer side of the right end of the coiling block is provided with a lifting brake ring through an end cover. An inner gear ring is pressed to the inner side of the right end of the coiling block. A lifting band-type brake is installed on the lifting brake ring. A center gear is installed at the right end of the winch shaft. Three planetary gear supports are evenly distributed. Each planetary gear support is provided with a planetary gear shaft which is provided with a planetary gear through a single-row radial ball bearing. Each planetary gear support is sealed through an installed sealing cover. The winch is in different states by operating the lifting band-type brake or the braking band-type brake, the winch can ascend, descend, brake the drill and the like, the lifting and braking effects of the winch are improved, and operation meets requirements.
