The working principle is as follows: when the device is used, the device is moved to the side of the telegraph pole, then the device is moved forwards and backwards to be fixed with the telegraph pole through the clamp 17, then the device is moved leftwards and rightwards to enable the wire pulley 52 to be positioned at the position right below the insulator for installing the cable on the cross arm, the first locking bolt 15 is then tightened, and the second hydraulic cylinder 32 is then controlled, so that the large arm 19 lifts the small arm 21, while the first hydraulic cylinder 27 is simultaneously controlled, the first mounting plate 22 is adjusted by the small arm 21, so that the first mounting plate 22 is always kept in a state of being relatively parallel to the horizontal plane in the process of lifting the large arm 19, when the top surface of the first mounting plate 22 is close to the bottom of the cross arm, the lifting operation of the large arm 19 is stopped, and at this time, the two wire pulleys 52 on the first mounting plate 22 are respectively positioned at two sides of the insulator of the mounting line, and at this time, the top of the wire pulley 52 is slightly higher than the top of the insulator. At this time, the tail end of the cable is sequentially wound from the tops of the two wire pulleys 52, then the tail end of the cable sequentially passes through the two guide cylinders 35 and the threading groove 54 and then is fixed on the wire coil 5, when the tail end of the cable passes through the two guide cylinders 35, the tail end of the cable simultaneously passes through the cavity between the two arc-shaped clamping plates 44, because the guide cylinders 35 are composed of the two arc-shaped plates 36, the second locking bolt 39 is unscrewed and the arc-shaped plates 36 can be pulled through the handle 53, so that the two arc-shaped plates 36 are separated, the threading work of the tail end of the cable is convenient, when the tail end of the cable passes through the cavity between the two arc-shaped clamping plates 44, the two arc-shaped clamping plates 44 are firstly pressed down respectively, the two arc-shaped clamping plates 44 can rotate relative to each other by taking the axis of the arc-shaped guide rod 48 as the axis, and the distance between the two arc-shaped clamping plates 44 is increased, so that the threading work of the tail end of the cable is convenient.
After the work is done, firstly, the motor 9 is started, so that the output shaft of the motor 9 drives the rotating shaft 6 to slowly rotate through the first gear 7 and the second gear 10, the rotating shaft 6 drives the wire coil 5 to synchronously rotate when rotating, the wire coil 5 winds the cable when rotating, when the lowest point of the cable between two telegraph poles is suspended, the electric telescopic rod 42 can be started, the telescopic end of the electric telescopic rod 42 performs reciprocating telescopic motion when in operation, when the telescopic end of the electric telescopic rod 42 retracts, the two sleeves 40 are synchronously driven to descend, the two arc-shaped clamping plates 44 are synchronously driven to descend when the two sleeves 40 descend, when the two arc-shaped clamping plates 44 descend, under the action of the spring 49, the spring 49 always gives extrusion force to the arc-shaped clamping plates 44 towards the cable direction, so that the cable can be clamped to synchronously descend when the two arc-shaped clamping plates 44 descend along with the descending of the telescopic end of the electric telescopic rod 42, the cable is tensioned, therefore, the force received when the cable is wound on the movable wire coil 5 is effectively shared, and the load on the motor 9 is reduced, so that the power of the motor 9 adopted by the device can not be too large, when the two arc-shaped clamping plates 44 ascend along with the expansion ends of the electric telescopic rods 42, the inner arc surfaces of the arc-shaped clamping plates 44 cling to the surfaces of the cables and slide to ascend, and the cables cannot be clamped to synchronously move as the arc-shaped clamping plates 44 descend, so that with the operation of the electric telescopic rods 42, the cables are intermittently pulled down between the two arc-shaped clamping plates 44 until the cables between two telegraph poles reach the tightening requirement, the motor 9 and the electric telescopic rods 42 are simultaneously stopped, due to the arrangement of the two arc-shaped clamping plates 44, even if the motor 9 and the electric telescopic rods 42 stop, the cables wound on the wire coil 5 cannot be pulled reversely, and because the cables can be clamped between the two arc-shaped clamping plates 44 when the cables are pulled reversely, at the moment, the cable on the insulator is fixed on the insulator, so that the cable between the two telegraph poles can be tightened. Due to the arrangement of the two wire pulleys 52, when the cable is tensioned, the cable cannot touch the cross arm at all, so that the cross arm cannot be stressed by any force in the process of tensioning the cable, and the purpose of protecting the cross arm is effectively achieved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
