Abstract
The utility model discloses a spiral winding drum. The utility model aims to provide a spiral winding drum capable of ensuring that the hoisting force of hoisting points is consistent and the hosting force is kept to be balanced. The spiral winding drum comprises a winding drum and steel wire ropes; at least two parallel threads rotating in the same direction are arranged on the winding drum; a steel wire rope is entwined in each thread groove; and at least two steel wire ropes are educed from the winding drum. The spiral winding drum comprises a winding drum and steel wire ropes; at least two parallel threads rotating in the same direction are arranged on the left side of the winding drum; at least two parallel threads which rotate in the same direction and are symmetrical to the left side of the winding drum are arranged on the right side of the winding drum; a steel wire rope is entwined in each thread groove; and at least four steel wire ropes are educed from the winding drum. Because the hosting force of a plurality of hosting pints educed on the winding drum is consistent, when the hoisting points are used for hoisting a heavy object, the balance of the heavy object can be kept, thereby reducing the occurrence of potential safety hazard. The utility model is mainly used for cranes.
Description
Technical field
The utility model relates to the reel on the electric block, particularly a kind of thread winding drum.
Background technology
When the weight of two suspension centres lifted by crane, with drawing two steel ropes under the suspension centre, when coming hoisting heavy, in the lifting process, weight was difficult to keep balance, all around rocks, and causes the generation of accident easily.When four weights more than the suspension centre lift by crane, need 2-4 above electric block to lift by crane simultaneously, because of the very difficult uniformity that keeps of the lifting force of each electric block, in weight vertically hoists process synchronously, different because of the lifting force of each Heave Here, can cause lifting by crane the thing run-off the straight and produce potential safety hazard.
Summary of the invention
The technical matters that the utility model solves provides a kind of lifting force unanimity that can make the Heave Here, keeps a kind of thread winding drum of lifting thing balance.Technical solutions of the utility model are finished like this, a kind of thread winding drum includes reel, steel rope, it is characterized in that: the screw thread that is provided with two equidirectional rotations arranged side by side on the reel at least, all be tied with a steel rope in each thread groove, from reel, draw two steel ropes at least.The screw thread of equidirectional rotation arranged side by side has two on the reel, draws two steel ropes from reel.A kind of thread winding drum, include reel, steel rope, it is characterized in that: the reel left side is provided with the screw thread of two equidirectional rotations arranged side by side at least, the right side of reel is provided with the screw thread with symmetrical at least two the equidirectional rotations arranged side by side in reel left side, all be tied with a steel rope in each thread groove, from reel, draw four steel ropes at least.The screw thread of the equidirectional rotation arranged side by side of the reel left and right sides respectively has two, draws four steel ropes from reel.Technique effect of the present utility model is: because of draw a plurality of suspension centres on a reel, the lifting force of a plurality of suspension centres is consistent, with weight of a plurality of suspension centre liftings the time, just can keep the balance of weight, reduces the potential safety hazard that tilts to take place because of weight.
Description of drawings
Fig. 1 draws the block diagram of two steel ropes from reel for the utility model; Fig. 2 draws the block diagram of four steel ropes from reel for the utility model.
Drawing explanation: 1, track adjusting wheel; 2, reel; 3, screw thread; 4, steel rope.
The specific embodiment
In conjunction with the embodiments the utility model is further described, as shown in Figure 1, reel 2 on the electric block is provided with the screw thread 3 of two equidirectional rotations arranged side by side, all be provided with steel rope 4 in each thread groove, draw two steel ropes 4 from reel 2, produce two Heave Heres by track adjusting wheel 1, because of lifting force all from a reel 2, so the lifting force of two Heave Heres equates, can effectively maintain the balance of weight in the lifting process of two Heave Heres.During operation, steel rope 4 moves in thread groove separately, is independent of each other.
As shown in Figure 2, reel 2 left sides on the electric block are provided with the screw thread 3 of two equidirectional rotations arranged side by side, are equipped with steel rope 4 in each thread groove, draw two steel ropes 4 from the reel left side, produce two Heave Heres by track adjusting wheel; Reel 2 right sides on the electric block are provided with the screw thread 3 with symmetrical two the equidirectional rotations arranged side by side in reel 2 left sides, are equipped with steel rope 4 in each thread groove, draw two steel ropes 4 from the reel left side, produce two Heave Heres by track adjusting wheel 1; Derive four suspension centres on such reel 2, the power of hanging of these four suspension centres is all from same reel 2, thus the lifting force of four suspension centres equate, when lifting has the weight of four suspension centres, can keep weight balance in the lifting process.During operation, steel rope 4 moves in thread groove separately, is independent of each other.
The utility model can be combined into hoisting mechanism with miscellaneous equipment, can realize many suspension centres, lifting synchronously, such as rubbish hang, gate hangs etc.
