Abstract
The utility model discloses an electric hoist, including motor, commutator, transmission shaft, lead screw and lifting platform, the commutator includes commutator in the middle of two end commutators and, and the three is in one linely, in the middle of and the commutator for T shape commutator, the input that the output shaft of motor passes through universal joint and T shape commutator links to each other, be provided with between middle commutator and the end commutator that corresponds the transmission shaft, the output that universal joint and middle commutator are passed through to the one end of transmission shaft links to each other, and the input that the other end passes through universal joint and end commutator links to each other, the output of end commutator below is connected with one through the universal joint the lead screw, the lifting platform sets up between two rhizoid poles to install respectively on the lift nut that corresponds the lead screw at the left and right both ends of lifting platform. Compact structure, safe and reliable is used to simple operation, high efficiency.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of motor hoist.
Background technology
In some outdoor activities, especially large-scale activity, often need to use more material and facility, and these material and facilities all needs to rise to certain altitude mostly, some function place could be arrived, at this moment just need to use lift system to be risen to set height.
Utility model content
The utility model aims to provide a kind of compact conformation, simple operation, efficient, safe and reliable motor hoist, and can be used for vehicle-mounted installation.
For this reason, the technical scheme that the utility model adopts is: a kind of motor hoist, comprise motor, commutator, transmission shaft, screw mandrel and lifting platform, described commutator comprises commutator in the middle of two termination commutators and, three is in one line, and middle commutator is T-shaped commutator, the output shaft of described motor is connected by the input end of universal-joint with T-shaped commutator, described transmission shaft is provided with between described middle commutator and corresponding termination commutator, one end of described transmission shaft is connected by the mouth of universal-joint with middle commutator, the other end is connected by the input end of universal-joint with termination commutator, mouth below the commutator of described termination is connected with a described screw mandrel by universal-joint, described lifting platform is arranged between two rhizoid bars, and a left side for lifting platform, right two ends are arranged on the lifting nut of corresponding screw mandrel respectively.
Further, described termination commutator is L shape commutator.
Closer, described motor is fixed on the top in compartment by motor mounting rack, and described commutator is arranged in compartment; Can vehicle-mounted installation be carried out, easy to carry.
The beneficial effects of the utility model are: compact conformation, simple operation, and replace hand hoisting with mechanical lifting, work efficiency is higher; And article carrying platform is between two rhizoid bars, synchronism is good, operates more safe and reliable.
