Abstract
The utility model relates to a cable drum device for a crane, which is composed of a speed reducing motor, a brake and a cable drum, and the device is additionally provided with a friction clutch, a cable guiding roller and a worm speed reducer. Owing to the friction clutch, the running speed of the crane comes into step with the coiling speed of the cable drum, avoiding the problem that a cable is broken due to stress. In addition, owing to the worm speed reducer, a cable spooling roller can uniformly spool cables, solving the two problems when the existing crane works.
Description
What the utility model was announced is the transfer crane cable drum device, specifically is a kind of cable drum device that has friction clutch and cable guiding roller.
Existing transfer crane cable drum device has weight hammer type, spring loaded, hydraulic moment changeable formula etc., owing to do not have friction clutch and cable guiding roller.The speed of the folding and unfolding speed of its cable and hoisting crane operation is asynchronous, and cable drum can not be thrown off with driving device, causes cable to be subjected to pulling force excessive, and breaks the consequence of cable, and is particularly more difficult to major diameter, length twisted and released of the cable.
The purpose of this utility model provides a kind of cable drum device that has friction clutch, and is synchronous with the folding and unfolding speed and the hoisting crane running velocity that guarantee cable drum.The stressed excessive cable of breaking when avoiding producing effects owing to cable.
Structure of the present utility model as shown in drawings;
On reducing motor, have drg and friction clutch.Power-transfer clutch is connected a cable guiding roller with the cable electricity to bar through the cross lever.The cable drum axle is right-hand a worm reducer.
Course of action of the present utility model is, when hoisting crane during, reducing motor no power at the cable power supply point, and the drg braking, friction clutch is in engagement state, and sprocket wheel does not rotate, and cable drum is static, and cable is in relaxed state.
When hoisting crane leaves the cable power supply point, reducing motor is no power still, the drg braking, and cable is in tension, the cable guiding roller is swung aside, the cable pilot bar rotates, pulling cross lever, cross lever pulling clutch slipper yoke, shift fork is stirred the power-transfer clutch sliding sleeve and is moved right, thereby make clutch be in disengaged condition, this moment, cable dragged cable drum, and sprocket wheel freely rotates.Cable drum is rotated further, when cable occurs when loose, the cable guiding roller returns to original position, and cable pilot bar, cross lever and clutch slipper yoke counteragent reset the power-transfer clutch sliding sleeve left, this moment, power-transfer clutch was in engagement state, because reducing motor is no power still, drg is still in braking, so sprocket wheel stops operating, cable drum constantly is in and stops-change, and change-stops the state cable laying.
When hoisting crane when the cable power supply point moves, reducing motor energising, drg is opened, clutch engagement, two hinge wheels drive mutually, cable drum rotates, the cable drum take-up.When cable drum take-up speed during greater than the cart running velocity, tension appears in cable, and the cable guiding roller swings aside again, under cable pilot bar, cross lever and clutch slipper yoke effect, power-transfer clutch is in disengaged condition again, the stall of cable tube, the reducing motor idle running of still switching on.When cable returns to relaxed state again, power-transfer clutch is in engagement state again, and reducing motor continues to drive the cable drum take-up again.Cable drum constantly is in and change-stops, and stops-change the state take-up.
In order to make cable marshalling on cable drum, hinge wheel is housed on cable drum, hinge wheel drives minor sprocket rotates the crank on the worm reducer, by connecting rod rocking bar is waved by the velocity of rotation of cable drum, evenly arranges cable thereby drive cable-arranging roller.
This reality is novel to make that cable drum can be synchronous with the hoisting crane speed of travel in the speed of folding and unfolding cable owing to have friction clutch, and the phenomenon of having avoided breaking cable occurs.Make it to reach even row's cable owing to increased cable-arranging roller again.Two problems when having solved existing crane job.
Accompanying drawing is the utility model structural representation
Realization of the present utility model relates to machine up and assembling, with reference to specification sheets and accompanying drawing, can realize by the known technology that machine up is installed.
