Abstract
The utility model discloses a double-drive electric block comprising a winding drum, a steel wire, a hanger and a lifting device. For the winding drum, the inner periphery uses a gear ring and the center of uses a bearing to symmetrically install two speed reducers ends; the input shafts of all the speed reducer are respectively connected with a synchronous motor by a coupler toward the outer end; bolts are fixed between all the motors and the winding drum; and a ball and an oil seal are respectively arranged at the joint of the two ends of the winding drum and the speed reducers. The double-drive electric block installs the two synchronous motors and the two ends of the speed reducers in one winding drum symmetrically, and has the advantages of small volume, large lifting tonnage and safe and reliable work.
Description
Technical field:
The utility model relates to starter motor, particularly a kind of dual-driven electric cucurbit that drives between reductor and reel with double-motor.
Background technology:
Existing electric block, the engine installation that drives between reductor and reel is by a reductor and reel of a motor-driven and lifting appliances such as steel rope and suspension hook thereof.The shortcoming that exists is that the lifting tonnage is little.Existing C D type electric block exists also that volume is big, noise is big, unreasonable structure, waste energy, hoisting capacity generally is no more than 16 tons.
Summary of the invention:
The purpose of this utility model provides a kind of rational in infrastructure, and volume is little, the lifting tonnage is big, save the energy, dual-driven electric cucurbits that can two brakings.
The technical solution of the utility model is finished as follows, it includes reel, steel rope, suspension hook and lifting appliance, it is characterized in that: on a reel inner periphery, be symmetrically installed with two reductors with bearing to two ends with gear ring, center, be connected with a synchronous dynamo outward with coupler respectively on each reductor input shaft, be fixed with bolt between each motor and the reel, be respectively equipped with ball and oil sealing at reel two ends and reductor junction.The utility model is installed in the reel with two synchronous dynamos and reductor two ends symmetry, has the advantage that volume is little, the lifting tonnage is big, safe and reliable.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is to the two ends symmetry two reductors 3 to be installed with bearing 9 with gear ring 8, center on reel 2 inner peripherys, be connected with a synchronous dynamo 5 outward with coupler 6 respectively on each reductor input shaft, between each motor and the reel bolt is arranged, be respectively equipped with ball 7 and oil sealing 4 at reel two ends and each reductor junction.Steel rope 1, suspension hook 10 and lifting appliance remain unchanged.Owing to adopt two motors to drive, and with bearing reductor be connected with reel with gear ring, so, the utlity model has rational in infrastructure, the advantage that the lifting tonnage is big.
