Abstract
The utility model relates to a single-phase hoisting machine, which comprises a driving device and a hoisting machine main body connected with the driving device, wherein the driving device comprises a three-phase motor. The single-phase hoisting machine also comprises a frequency converter, wherein the input of the frequency converter is connected with a single-phase AC (alternating current) power supply; the output of the frequency converter is electrically connected with the three-phase motor; and the frequency converter converts the single-phase AC power supply into a three-phase AC power supply. As the frequency converter is adopted to convert the single-phase power supply into the three-phase power supply, so as to drive the three-phase motor to operate and make full use of excellent performances such as braking and the like of the three-phase motor; moreover, the single-phase hoisting machine has reliable performances, and can be used on an occasion free of the three-phase power supply, and has wide application range.
Description
Technical field
The utility model relates to a kind of single-phase winch.
Background technology
Existing single-phase winch uses single phase poaer supply to drive monophase machine work usually, because winch is used for hoisting operation, therefore, requires motor to have braking function, avoids dangerous.And common monophase machine does not possess braking function, and performance and unreliable, and promptly starting ability is poor at full capacity, and motor easily generated heat when the oepration at full load time was long, had potential safety hazard during use, and when working level is high slightly, use will be restricted.
The utility model content
The purpose of this utility model provides a kind of dependable performance, the wide single-phase winch of range of use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of single-phase winch, comprise actuating device, the winch body that is connected with described actuating device, described actuating device comprises three phase electric machine, described single-phase winch also comprises frequency converter, the input of described frequency converter is connected with single phase alternating current power supply, the output of described frequency converter and described three phase electric machine are electrically connected, and described frequency converter is converted to three-phase alternating-current supply with described single phase alternating current power supply.
Preferably, described three phase electric machine is the three-phase braking motor.
Preferably, described three phase electric machine is a threephase asynchronous machine, described actuating device also comprises worm reducer, and the output shaft of described threephase asynchronous machine is connected with described worm reducer, and the output of described worm reducer is connected with described winch body.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
Because the utility model adopts frequency converter that single phase poaer supply is converted to three phase mains, and then drives three phase electric machine work, can give full play to the excellent properties such as braking of three phase electric machine, dependable performance, simultaneously, can use in the occasion that does not have three phase mains, Applicable scope is extensive.
