The working principle is as follows: when the cable drum is used, the mounting shaft 13 is inserted into the cable drum 11, so that the cable drum 11 is fixed on the mounting shaft 13, the fixed clamping blocks 14 are positioned on the left side and the right side of the cable drum 11 and are symmetrical about the cable drum 11, then the crank handle I6 is rotated to enable the hoisting device to descend until the lifting hooks 20e are contacted with the left end and the right end of the mounting shaft 13, then the lifting hooks 20e are hung in the lifting rings 15 respectively and correspondingly by hand, then the crank handle I6 is rotated to vertically hoist the mounting shaft 13 and the cable drum 11 fixed on the mounting shaft 13 through the hoisting device, labor is saved, when the fixed clamping blocks 14 on the left side and the right side of the mounting shaft 13 are respectively clamped on the fixed clamping grooves 17c arranged on the fixed rods 17a correspondingly, the crank handle I6 is stopped to rotate, then the fixed nuts 17b are rotated to enable the fixed clamping blocks 14 on the two sides of, further fixing the cable disc 11 on the locking mechanism, then sequentially passing the free end of the cable 5 wound on the cable disc 11 through the tension bracket 2 and sequentially passing each tension wheel 2d from left to right, then entering the adjusting bracket 3, passing between a first compression roller set and a second compression roller set consisting of a plurality of compression rollers 3d, and leaving from the right end of the adjusting bracket 3, when discharging the cable (as shown in fig. 2), sequentially passing the cable 5 through the tension bracket 2 by a plurality of tension mechanisms according to the sequence from left to right, then entering the adjusting bracket 3, finally passing through between the first compression roller set and the second compression roller set, and gradually reducing the diameter of the cable 5 wound on the cable disc 11 in the process of paying off, namely gradually reducing the length of the cable discharged per rotation circle of the cable disc 11, under the action of the plurality of tensioning mechanisms, the difference of the lengths of the cables released from the cable drum 11 in each rotation can be made up, namely, the lengths of the cables released from the right end of the adjusting bracket 3 in each rotation of the cable drum 11 are the same (when the cable drum 11 rotates for the first rotation, the paying-off length is longer, at the moment, the compression amount of the tensioning spring 2b in each tensioning mechanism is smaller, when the cable drum 11 continues to rotate for the second rotation, the cable released from the cable drum 11 is smaller than the cable released last time, at the moment, the compression amount of the tensioning spring 2b in each tensioning mechanism is larger than the compression amount of the last time, at the moment, the cable is in a straightened state relatively, so that the length of the cable released from the right end of the adjusting bracket 3 is the same as the length of the cable released from the last time, the difference of the lengths of the cables released from the cable drum 11 in each rotation is made up, and the cable can be prevented from falling off from the cable drum 11 due to cable being loosened in the paying-off process, and therefore, the cable 5 is prevented from being dragged on the cable drum 5 loosely, the cable 5 is abraded, and the paying-off quality is poor, in addition, the cable 5 is wound on the cable drum 11 for a long time, so that the cable is in a bending state in the paying-off process, and when the cable passes through the cable straightening mechanism, the bent cable can be straightened through the combined action of the first compression roller group and the second compression roller group.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
