Abstract
The utility model discloses a synchronous hoisting reel device for cranes, which comprises a cable reel and a wire rope reel, wherein a cable guide rod is mounted on the side of the cable reel through a support, a cable is pressed by a counter-roller on the cable guide rod, an input shaft of the cable reel is connected with a slip ring box, a driven chain wheel is mounted on the input shaft of the slip ring box, and a driving chain wheel and the wire rope reel are mounted on the end of an output shaft of a hoisting speed reducer. The driving chain wheel is connected with the driven chain wheel through a chain, and the surface of the counter-roller is a concave arc-shaped surface machined according to the cable. The cable guide rod can be adjusted by springs on both sides of the guide rod support. The synchronous hoisting reel mechanism for cranes has the following advantages that: (1) the mechanism realizes the synchronism between the lifting speed of the cable and the lifting speed of a wire rope, thus effectively preventing the phenomenon that the cable can be pulled to be broken due to the overhigh lifting speed of a lifting appliance; and (2) meanwhile, by means of the cable guide rod, the mechanism prevents the cable from being wound in disorder on the cable reel, thus enhancing the reliability of power supply for the lifting appliance.
Description
Technical field:
The utility model relates to the hoisting drum device on a kind of hoisting crane, is specially adapted to the synchronization lifting of cable drum and steel rope.
Background technology:
At present, the generally not ultra 20m/min of the rising or falling speed of general-purpose overhead crane, when lifting mechanism had the suspender (like magnetic chuck, hydraulic grab etc.) of needs power supply, power supply was supplied power to suspender through the cable drum that has spring.This device is to be power with the volute spring in the reel in the lifting process of suspender, utilizes the energy storage of spring to batch cable automatically.But work as rising or falling speed much larger than 20m/min, if also utilize this device, rely on the power of volute spring to discharge cable, suspender is in the decline process so, and cable is very big with the pulling force that bears, to such an extent as to cable is broken.And this cable drum causes cable disorderly to twine when batching cable easily, to such an extent as to the cable slippage goes out cable drum, causes cable drum not supply power by the bio-occlusion suspender.On the other hand, this device is in long use, and the elastic force of reel contained spring lost efficacy easily, caused cable drum can not batch cable automatically.
Summary of the invention:
The task of the utility model is that a kind of lifting mechanism cable drum of proposition and cable drum are synchronous, and cable is consistent with the suspender rising or falling speed, avoids synchronously the hoist roll device of cable on a kind of hoisting crane that disorderly twines on the reel.The task of the utility model is to accomplish like this; It comprises cable drum, cable drum; It is characterized in that: the cable guide rod is installed in the side of cable drum through support, and the anti-roller on the cable guide rod is pressed on the cable, and the input shaft on the cable drum is connected with the slip ring case; On the input shaft of slip ring case driven sprocket is housed, the output axle head of the reductor that hoists is equipped with drive sprocket and cable drum.Drive sprocket is to be connected through chain with driven sprocket, and described anti-roller wheel face is the matrix cambered surface according to the processing of cable cotton rope.The cable guide rod can be regulated according to the spring of guide bar support both sides.The utlity model has following effect: 1, this device has been realized the synchronism of cable and steel rope rising or falling speed, has avoided the suspender lifting velocity too fast effectively, the phenomenon that cable is broken.2, simultaneously, the phenomenon that this device has avoided cable on cable drum, disorderly to twine through the cable guide rod device has improved the reliability to the power supply of suspender.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
Drawing explanation: 1, cable guide rod, 2, cable drum, 3, the slip ring case, 4, driven sprocket, 5, chain, 6, drive sprocket, 7, the reductor that hoists, 8, cable drum.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, cable guide rod 1 is installed in cable drum 2 sides through support, and the anti-roller on the cable guide rod is pressed on the cable; Anti-roller wheel face is the matrix cambered surface that directly processes according to the cable cotton rope, and the cable guide rod can be regulated according to the spring of guide bar support both sides, and the input shaft on the cable drum 2 is connected with slip ring case 3; Driven sprocket 4 is housed on the input shaft of slip ring case; Output axle head at the reductor 7 that hoists is equipped with drive sprocket 6 and cable drum 8, and drive sprocket is to be connected through chain with driven sprocket, and motor shaft end is connected with the reductor input shaft end through coupler; Electrical motor passes to reductor with power through transmission shaft, coupler during work; This reductor low speed end that hoists adopts two-way shaft extension, and an end of axle connects cable drum, and then the drive cable drum is rotated; The reel lay winding wire ropes promotes weight; And the other end is through having the chain gearing of certain speed ratio, through transmission shaft with its power through cable drum slip ring case, pass to reel at last to be rotated, make cable drum twine cable, give the suspender that hoists power supply.Cable drum and cable drum rotate synchronously like this, through the chain speed ratio is set, make the linear velocity of cable consistent with the hoist rope linear velocity.
