A double drum hoist

Abstract

The invention relates to a double winding drum hoist in the field of water conservancy machinery. An output shaft of a motor of the double winding drum hoist is in transmission connection with a first winding drum and a second winding drum, the output shaft end of the motor is connected with one end of a center shaft through a coupling, the other end of the center shaft is rotatably supported on a flange corresponding to the first winding drum, a driving gear is installed at one end of the center shaft close to a flange, and a first inner tooth ring and a second inner tooth ring are arranged in an inner cavity of the first winding drum. A first driven gear is arranged between the driving gear and the first inner tooth ring. A first center gear and a second center gear sequentially sleeve one side of the center shaft close to the driving gear, and a second driven gear is arranged between the first center gear and the second inner tooth ring. A third driven gear is arranged between the second center gear and the second inner tooth ring. A gear shaft of the third driven gear is fixed to a third gear frame, a main bearing is installed between a main bearing mounting base and the inner wall of the first winding drum, and the third gear frame is fixed to the main bearing mounting base. The double winding drum hoist is compact in structure, small in noise and good in heat dissipation.

Description

technical field [0001] The invention relates to a water conservancy mechanical equipment, in particular to a hoist for opening and closing a gate. Background technique [0002] The hoist is a special equipment used in the opening and closing of the gate. In the Chinese patent database, a direct-connected hoist is disclosed. Its publication number is: CN103015376A; the publication date is: April 3, 2013 ;The hoist is a direct-coupled single-point hoist, including a frame, a motor, a coupling, a connecting seat, a reducer, a wire rope drum, a wire rope, a balance pulley device and a movable pulley block; the motor is fixed through the connecting seat On the frame; the rotating shaft of the motor, the coupling, the input shaft and the output end of the reducer and the coaxial line of the wire rope reel are arranged; the reducer is a planetary gear reducer, including a fixed flange, a movable flange and an input Shaft; the fixed flange of the reducer is fixed on the frame, and ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the reducer and the wire rope drum of the direct-coupled hoist are independently manufactured and connected by flanges, which occupy a large volume and heavy weight, and the structure is not compact enough. The transmission of the reducer is located in the wire rope drum At one end, the torque transmission is unreasonable, which is easy to cause unbalanced load
