Abstract
The utility model discloses a lifting hook interval adjusting device for a large-scale gantry crane, which comprises a screw rod, a fixed seat, a power swing device, a coupler and a large nut, wherein the screw rod capable of rotating in situ is arranged on the fixed seat; the output shaft of the power swing device is connected with one end of the screw rod through the coupler; the large nut is screwed on the screw rod which is arranged on the fixed seat on the side far away from the coupler; the side of the large nut, which is far away from the fixed seat, is fixedly connected with a hoisting mechanism of the large-scale gantry crane; and a hook is arranged on the hoisting mechanism. Preferably, the power swing device is a three-in-one motor. The lifting hook interval adjusting device has the advantages that the structure is compact; the layout is reasonable; the operation is stable; and the hoisting deflection angle of a wire rope can be reduced to the maximum extent. Therefore, the service life of the wire rope is prolonged; and the safety production performance of the hoisting mechanism is improved.
Description
Technical field
The utility model relates to large-sized gantry and hangs, particularly large-sized gantry suspension hook spacing regulator.
Background technology
The large-sized gantry weight of slinging is big; Weight, volume and the shape of object of lifting is often different because of thing, on the object distribution of suspension centre also therefore different, if the suspension hook spacing of two groups of lifting mechanisms of the last dolly of gauntry crane is fixed; And the suspension centre gap ratio suspension hook spacing on the object is big or little; Can there be the drift angle of a certain size in lifting mechanism steel rope in the process of lifting object of going up dolly so, compares with the lifting process that does not have drift angle or little drift angle, and the existence of big drift angle can make the stressed increase of steel rope and object hanger; Thereby influence service life, the increase potential safety hazard of steel rope, and the position of object hanger is restricted also.
The utility model content
The purpose of the utility model provides a kind of large-sized gantry suspension hook spacing regulator; To reduce the drift angle of steel rope when lifting by crane object that large-sized gantry hangs as far as possible; Reduce the stressed of steel rope and object hanger, thereby prolong the service life of steel rope, reduce potential safety hazard.
The purpose of the utility model realizes through following technical scheme:
A kind of large-sized gantry suspension hook spacing regulator; Comprise screw rod, permanent seat, power turning gear, coupler and big nut; Said screw rod original position is arranged on the said permanent seat rotationally; The output shaft of said power turning gear connects with an end of said screw rod through coupler, and said big nut screws on the screw rod of said permanent seat away from a side of coupler, and it is fixedly connected away from the lifting mechanism that is provided with suspension hook that a side and the large-sized gantry of permanent seat hang.
Preferably, said power turning gear is three-in-one motor.
The principle of work of the utility model is: two groups of lifting mechanisms going up dolly respectively connect a cover suspension hook spacing regulator; The power turning gear drives the screw rod rotation; Thereby drive traversing (go up between dolly lifting mechanism and the vehicle frame and can relatively move) of the lifting mechanism that big nut reaches and big nut is fixedly connected through slide rail or wheel; Realize the adjusting of suspension hook spacing and reducing of steel rope lifting drift angle; And then reduce the stressed of steel rope and object hanger, and prolong the service life of steel rope, reduce potential safety hazard.
The beneficial effect of the utility model is: compact conformation, connection and reasonable arrangement, operate steadily, the drift angle that hoists of steel rope is farthest reduced, and improved the service life of steel rope and the safety in production performance of lifting mechanism thus.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the main TV structure scheme drawing of the large-sized gantry suspension hook spacing regulator of the utility model.
Fig. 2 is the plan structure scheme drawing of the large-sized gantry suspension hook spacing regulator of the utility model.
Among the figure: 1, screw rod; 2, permanent seat; 3, coupler; 4, big nut; 5, lifting mechanism; 6, three-in-one motor.
The specific embodiment
Shown in Fig. 1～2; The large-sized gantry suspension hook spacing regulator of the utility model; Comprise screw rod 1, permanent seat 2, power turning gear, coupler 3 and big nut 4; Said screw rod 1 original position is arranged on the said permanent seat 2 rotationally; The output shaft of said power turning gear connects with an end of said screw rod 1 through coupler 3, and said big nut 4 screws on the screw rod 1 of said permanent seat 2 away from a side of coupler 3, and it is fixedly connected away from the lifting mechanism that is provided with suspension hook 5 that a side and the large-sized gantry of permanent seat 2 hang.
Preferably, said power turning gear is three-in-one motor 6.
Claims (2)
1. large-sized gantry suspension hook spacing regulator; It is characterized in that: comprise screw rod, permanent seat, power turning gear, coupler and big nut; Said screw rod original position is arranged on the said permanent seat rotationally; The output shaft of said power turning gear connects with an end of said screw rod through coupler, and said big nut screws on the screw rod of said permanent seat away from a side of coupler, and it is fixedly connected away from the lifting mechanism that is provided with suspension hook that a side and the large-sized gantry of permanent seat hang.
