DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Please refer to Figures 1-4 In the embodiments of the utility model, a high-voltage line construction tight line device includes frame 1, round roller 2, two steel wire ropes 3, hook 4 and tight line gear 5; frame 1 is the connecting part of the whole device, used for fixing various parts of the device;

[0029] Round roller 2 is rotatably connected inside frame 1, there are two round rollers 2 and they are symmetrically distributed, one end of round roller 2 penetrates through the side surface of frame 1 and is fixedly connected with straight gear 21, two steel wire ropes 3 are respectively wound and fixed on the outer wall of round roller 2 at the corresponding positions, hook 4 has two and is respectively fixedly connected with the end of steel wire rope 3 at the corresponding position, two round rollers 2, two steel wire ropes 3 and two hooks 4 are arranged, used for hooking the two ends of two cables, which can be used to pull the two cable ends farther apart.

[0030] Tight line gear 5 is rotatably connected on the side surface of frame 1 through a rotating shaft, tight line gear 5 is in meshing transmission with two straight gears 21, the outer wall bottom end of the rotating shaft is fixedly connected with ratchet 51, the rotation of tight line gear 5 drives two straight gears 21 to drive round roller 2 at the corresponding position to rotate respectively, so as to simultaneously make two round rollers 2 wind two steel wire ropes 3 at the corresponding positions respectively.

[0031] Clamping mechanism 6 is arranged on the side surface of frame 1 and can limit ratchet 51 from reversing, clamping mechanism 6 is mainly used for limiting ratchet 51 from reversing.

[0032] Specifically, first, disengage the locking mechanism 6 from the ratchet 51. Then, stretch the two steel wire ropes 3 to a certain length and hook the hook 4 onto the corresponding cable (to hook the cable end, you can first use a fastener to fix the cable end, and then use the hook 4 to hook the fastener; the fastener is existing technology, and its specific use will not be elaborated here). Then, lock the locking mechanism 6 onto the ratchet 51, and the rotation of the tensioning gear 5 causes the two spur gears 21 to drive the corresponding rollers 2 to rotate. The rotating rollers 2 can wind up the steel wire ropes 3 at the corresponding positions, thereby pulling the ends of the two cables towards the frame 1 (according to...). Figure 1 As can be seen, the winding direction of the two wire ropes 3 and the two spur gears 21 rotating in the same direction can bring the ends of the two cables closer to each other. When the hook 4 contacts the frame 1, the hook 4 is restricted by the frame 1, and there will still be a certain gap between the two cables. Therefore, the ends of the two cables can be connected by a conductive connector, and then the hook 4 can be released from the ratchet 51 by the snap-fit ​​mechanism 6, so that the two wire ropes 3 can be released and the hook 4 can be separated from the cable.

[0033] Example 1

[0034] like Figure 3 As shown, in this embodiment, a rocker arm 52 for driving the tensioning gear 5 to rotate is fixedly connected to one end of the rotating shaft, and retaining rings 22 for preventing the wire rope 3 from getting stuck are fixedly connected to both ends of the outer wall of the roller 2.

[0035] In this embodiment, the rotation of the crank handle 52 can cause the tensioning gear 5 to drive the two spur gears 21 to rotate. The rotating spur gears 21 can cause the roller 2 to wind up the steel wire rope 3 at the corresponding position, thereby bringing the ends of the two cables closer together so that the workers can connect and fix the two cables through the connector. The retaining ring 22 can prevent the steel wire rope 3 from getting stuck between the roller 2 and the inner side of the frame 1 during the winding process.

[0036] Example 2

[0037] like Figure 4 As shown, in this embodiment, the snap-fit ​​mechanism 6 includes a rectangular sleeve 61, a slider 62 is slidably fitted inside the rectangular sleeve 61, a snap-fit ​​tooth 63 is fixedly connected to one side of the slider 62 and engages with the ratchet 51, a spring 64 is fixedly connected between the slider 62 and the rectangular sleeve 61, connecting blocks 65 are fixedly connected to both opposite sides of the rectangular sleeve 61, a screw 66 is rotatably connected to one side of the frame 1 and engages with the connecting block 65 at the corresponding position, a nut 67 is fixedly connected to the top of the screw 66, a limiting rod 68 is fixedly connected to one side of the frame 1 at the position corresponding to another connecting block 65 and slides through the connecting block 65 at the corresponding position, and one side of the snap-fit ​​tooth 63 is an arc-shaped surface.

[0038] In the embodiment, the rotation of the handle 52 can not only rotate the wire tightening gear 5, but also rotate the ratchet 51, and since the side surface of the catch 63 is arc-shaped, the rotating ratchet 51 can press the catch 63 to press the slider 62 into the rectangular sleeve 61 and compress the spring 64, and when the ratchet 51 stops rotating, the catch 63 can lock the ratchet 51 to prevent the ratchet 51 from rotating reversely, and since the two cables are pulled to the maximum extent, the ratchet 51 and the catch 63 will be subjected to reverse force, so that the catch 63 is difficult to be directly moved by the finger, and thus the staff can rotate the nut 67 by using the wrench to rotate the screw rod 66, and since the screw rod 66 is penetrated and screwed with the connecting block 65 at the corresponding position, the rotating screw rod 66 can drive the rectangular sleeve 61 to move the slider 62 and the catch 63 upwards, so that the catch 63 is separated from the ratchet 51.
