Abstract
The utility model discloses a kind of double power driven electric hoist, including electric block housing, connecting plate is equipped with above the electric block housing, the left and right of the connecting plate comes both ends and is both provided with running gear, the centre position of the electric block housing is provided with electric gourd drum, the left and right ends of the electric gourd drum are respectively provided with the identical motor of set of parameter, retarder and brake, connected between the electric gourd drum and retarder by shaft coupling, each motor is connected to power supply by frequency converter, the frequency converter is controlled by external potentiometer.The beneficial effects of the utility model：Using double dynamical driving, when retarder broken teeth, the situation for being driven axle fracture occurs in electric block, the torque of braking can be transmitted above reel, effectively prevent the generation of security incident, while can also find corresponding failure in time.
Description
Technical field
Hoisting machinery technical field is the utility model is related to, relates in particular to a kind of double power driven electric hoist.
Background technology
Electric block is a kind of common hoisting machinery of many operation fields, and existing electric block is by motor, subtracts
The components such as fast device, brake and reel composition, wherein brake and motor are the structure type being connected as a single entity, motor and braking
Device mutually interlocks in work, and the electric block of this structure is when retarder broken teeth occur, being driven the situation of axle fracture, then
The torque of braking can not be passed to above reel, therefore reel will rapidly fall, and for such case once occurring, just having can
Serious security incident can occur, or even the life security of worker can be seriously affected.
Utility model content
The problem of in correlation technique, can be effective the utility model proposes a kind of double power driven electric hoist
The generation of security incident is reduced, while can also find corresponding failure in time.
To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of double power driven electric hoist, including electric block housing, the electric block housing top, which is equipped with, to be connected
Fishplate bar, the left and right of the connecting plate come both ends and are both provided with running gear, and the centre position of the electric block housing is provided with
Electric gourd drum, the left and right ends of the electric gourd drum are respectively provided with the identical motor of set of parameter, retarder and system
Dynamic device, is connected between the electric gourd drum and retarder by shaft coupling, and each motor is connected by frequency converter
To power supply, the frequency converter is controlled by external potentiometer.
Further, the connecting plate includes the first connecting plate and the second connecting plate, and first connecting plate and second connect
Fixed between fishplate bar using axis pin.
Further, second connecting plate is located at the top of the first connecting plate.
Further, first connecting plate has four, and second connecting plate has two.
Further, the electric gourd drum is connected by rolling bearing with electric block housing.
The beneficial effects of the utility model：Using double dynamical driving, when retarder broken teeth, transmission shaft folding occurs in electric block
During disconnected situation, the torque of braking can be transmitted above reel, effectively prevent the generation of security incident, while can also send out in time
Now corresponding failure.
