Operating mechanism
Electric car, running motor, running speed reducer, driven car and other components of the operating mechanism. Suspension of the main engine for reciprocating movement. Its operating speed is generally 20m/min, also can choose 30m/min. Lift more than 12m 1~5t, adding a driven car.
Two, electrical equipment
CD1, MD1 electric hoist electrical device has an electrical control box (0.25t), button switch and the connecting wire and other components.
The operating voltage of button switch is 380V or 36V, depending on the direction and symbols shown on the right button switch, push button control box, through the relay pull and disconnection, can control the hoist action.
Three, lifting structure
The lifting device comprises the main part of the machine, hoisting structure by lifting motor through the coupling through the reducer hollow shaft drives the roller to rotate, so that the wire rope around the drum in the hook driven device to rise or fall.
When the lifting height is H=6m, the input shaft of the motor shaft and the reducer is connected with a claw type coupling. H = 9m is added in the intermediate shaft and the rigid coupling. H is not less than 18m, with a support to strengthen the rigidity of the intermediate shaft, ensure smooth rotation.
Lifting motor
The hoisting motor adopts a conical rotor motor with large starting torque, so as to adapt to the frequent starting of the intermittent work. CD1 type hoist with ZD type single speed motor, MD1 type hoist with ZDS type double speed motor, ZDS motor constant speed and slow speed ratio is 10:1.
Speed reducer
0.25t hoist reducer for the straight tooth planetary transmission structure, the rest of the reducer are used helical gear three speed reduction. The gear and shaft is made of alloy structural steel or carbon steel processing, and after appropriate heat treatment to ensure the reliability and life. The box body and the box cover are made of cast iron. The utility model has the advantages of good shock absorption and reliable sealing.
Reel device
The drum is made of cast iron or seamless steel pipe, and the power is transmitted by spline.
Drum device is a central part of the hoist, through the balance beam and the operation mechanism is connected with the two ends of the hoisting speed reducer and motor are connected through the wire rope and hook device joint work, above the cover with stopper rod device.
The hook device
The hook is made of steel forging, and thrust ball bearings by hook beam and shell connection, make the hook hook operate freely, 5T and the following device is a single slip wheel, 10t and above is a double slide wheel.
