However, for heavier cables, it is difficult or even impossible to install the cable smoothly by manual dragging, which will bring hidden dangers to the workers' construction safety. After the cable is installed, its sag needs to be adjusted, and a special tightening device needs to be used to tighten the cable. However, the tightening device is heavy, which brings a considerable burden to the workers during the construction climbing process. Summary of the Invention

[0023] In one embodiment of the present application, the lower surface of the tensioning pressing plate 42 is provided with an arc-shaped concave groove 43. The surface of the arc-shaped concave groove 43 is provided with anti-skid lines.

[0024] In one embodiment of the present invention, a control crank is connected to one side of the cable winding device 7, and a ratchet limiting structure is provided on the other side of the cable winding device 7. The rotation direction of the cable winding device 7 is controlled by the ratchet in conjunction with a limiting plate with a locking tooth.

[0025] Working principle: When using a power distribution engineering construction wiring device of the present invention to carry out distribution network construction wiring, the relevant personnel first erect the wiring pole 1 to the designated position, and then fix one end of the cable to be erected, and adjust the counterweight according to the specifications of the cable to drag the weight to adjust the lifting force.

[0026] Among them, the relevant personnel insert the limit rod 17 into the first limit hole 20 of the required counterweight block 9, and then pass it through the second limit hole 19 on the adjustment rod 18, so as to achieve rapid adjustment of the counterweight, so that the counterweight adjustment device 10 can carry a specified number of counterweight blocks 9 for lifting during the lifting process. For example, if it is inserted into the second counterweight block 9 from the top to the bottom, the counterweight adjustment device 10 can carry these two counterweight blocks 9 for assistance during the lifting process.

[0027] It should be noted that the weight of each counterweight 9 is consistent. A single 5-10 kg counterweight 9 can be used. The required number of counterweights 9 can be selected according to the cable dragging weight. A counterweight scheme that is less than or equal to the dragging weight can be adopted, so that it will not be too difficult to pull down the cable locking device 11.

[0028] After the counterweight is adjusted, the relevant personnel can manually rotate the wire rope winding device 7 to reel in the wire rope 8, so that the wire rope 8 drags the cable locking device 11 downward, and at the same time, the counterweight adjusting device 10 is lifted up by the first fixed pulley 12 and the second fixed pulley 13 on the top of the lifting frame 5 until the cable locking device 11 reaches the optimal operating height for locking the cable. Then, the relevant personnel can fit the cable on the clamping plate 23 and pass it between the clamping rack 24 and the locking member 27, so that the arc-shaped tooth portion 28 on one side of the locking member 27 cooperates with the clamping rack 24 to clamp the cable. Then, the wire rope winding device 7 can be released so that the cable locking device 11 is gradually locked and dragged upward under the downward pressure of the counterweight adjusting device 10 until the counterweight adjusting device 10 and the counterweight block 9 reach the base 21, and the cable locking device 11 reaches the top of the lifting frame 5. Then, the construction personnel who have climbed to the top of the wire pole 1 can remove the cable for installation.

[0029] It should be noted that the wire winding device 7 adopts a winding reel structure, and one end is wound by the handle, and the other side is provided with a ratchet limiting structure (not enlarged in the figure, which is a conventional design and will not be described in detail), which controls the rotating direction of the wire winding device 7 through the ratchet cooperating with the limiting plate provided with the teeth, so as to fix the cable through the cable locking device 11 and other operations.

[0030] When the cable is installed, the relevant personnel take the cable off the cable locking device 11, and then the cable is installed in the wire installation device 3 through the arc-shaped lifting rod 40 on one side and the arc-shaped lifting rod 40 on the other side. Then repeat the above operation, and then the cable is sequentially installed through each wire installation rod 1. When the installation is completed, the relevant personnel will uniformly tighten the cable to a certain extent, and then the relevant personnel will fix the cable according to the needs through the wire clamping mechanism arranged in the middle of the wire installation device 3, so as to realize the installation of the cable.

[0031] For the cable tightening between each segment of the wire installation rod 1, the relevant personnel can adjust the tightening degree according to the needs. When adjusting the tightening, the relevant personnel can rotate the adjusting hand wheel 44 manually to drive the first transmission gear 47 to rotate, so that the lifting rod 35 is lowered under the cooperation of the rack on one side, and the tensioning plate 42 is lowered and the cable in the wire installation device 3 is pressed along the tensioning guide wheel 33 in the tensioning opening 32. At the same time, with the descent of the lifting rod 35, the movable arc-shaped push rod 36 is lifted under the support of the support part 38, so as to lift the first guide wheel 41 arranged at one end of the arc-shaped lifting rod 40, so as to lift the cable on the other side, so as to realize the tensioning effect. The relevant personnel can freely adjust the tightness of each segment of the cable.

[0032] It should be noted that the first transmission gear 47 is a worm that is adapted to the rack on the lifting rod 35 without affecting the normal transmission of the driving worm 45. The first transmission gear 47 is adapted to the rack on the lifting rod 35 to ensure smooth linkage of the structure. As another embodiment, the relevant personnel can replace the first transmission gear 47 with a normal worm gear adapted to the driving worm 45, and an integral straight gear driving part is arranged on one side of the worm gear. When the worm gear and the driving worm 45 mesh and rotate, the straight gear driving part on one side and the rack on the lifting rod 35 are normally meshed and transmitted.

[0033] In summary, the present invention provides a wire-laying device for power distribution engineering construction: a lifting frame is provided on one side of the wire-laying pole, and a steel cable winding device is provided on it in conjunction with a fixed pulley to realize the retraction and release of the steel cable, so that the end of the required cable to be erected is quickly locked and lifted by a cable locking device installed on the steel cable. Compared with manually dragging the cable to the pole, it is safer and more convenient to operate. Moreover, the counterweight block provided on one side of the lifting frame is combined with the counterweight adjustment device, and the counterweight can be flexibly adjusted according to the specifications of the cable, so that different power-assisting effects can be achieved when the cable is dragged, which can effectively reduce the burden of workers in lifting and dragging the cable, and also effectively improve work efficiency. The tensioning assemblies corresponding to the two sides of each stringing device can tighten and adjust the cables between the stringing poles on the corresponding side as needed after the cable is clamped by the cable clamping mechanism on the stringing device. The lifting rod is driven up and down by the adjusting hand wheel in conjunction with the transmission gear, so that it presses down and tightens the cables in the stringing device through the tensioning pressure plate. At the same time, the arc-shaped push rod and the arc-shaped lifting rod are linked to each other to lift the cables on the other side through the first guide wheel, thereby realizing the linkage of the two mechanisms to achieve the up and down tightening of the cables. The operation is simple and convenient, and the cables on the corresponding side can be flexibly tightened to different degrees according to needs. The locking member cooperates with the clamping rack on one side of the clamping plate to realize the rapid clamping of the cables through the linkage of the hoisting member and the connecting rod during the lifting process. The cable locking device with this structure can realize the rapid locking and release of the cables, bringing convenience to the construction personnel in the stringing operation.
