[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] like Figure 1-Figure 2 FIG. 1 shows a first embodiment of the overhead ground wire lifting device of the present invention.
[0017] The overhead ground wire lifting device in this embodiment is used to lift the overall load of the wire inside the suspension clamp, so as to replace the suspension clamp, and includes: a first frame 1, on which a first locking buckle 11 is provided; a second frame 2 connected to the first frame 1, the second frame 2 can be adjusted in position relative to the first frame 1, and the second frame 2 is provided with a second locking buckle 21; a lifting hook assembly 3, which includes: a screw rod 31, a connecting piece 32 connected to one end of the screw rod 31, a lifting hook body 33 connected to the connecting piece 32, and a screw rod sleeve 34 sleeved on the outside of the screw rod 31, and the screw rod 31 is threadedly connected to the screw rod sleeve 34.
[0018] The lifting hook assembly 3 is provided in two groups, and the two screw sleeves 34 are rotatably connected to the ends of the first frame 1 and the second frame 2 respectively.
[0019] Wherein: the lifting hook bodies 33 on the first frame 1 and the second frame 2 are respectively hooked with the wires extending from the opposite sides of the suspension wire clamp, and the screw rod sleeve 34 is screwed to move the linkage screw rod 31, the connecting piece 32 and the lifting hook body 33 up and down to loosen or tighten the wires inside the suspension wire clamp.
[0020] In specific implementation, the first frame 1 and the second frame 2 are block-shaped, and screw holes are respectively opened at the ends of the two frames 1 and 2. In this embodiment, there are multiple screw holes on the second frame 2, and the screw holes are distance adjustment holes 22. In implementation, screws 5 are respectively passed through the distance adjustment holes 22 on the second frame 2 and the screw holes on the first frame 1 to fix the two. By adjusting the position of the tightened distance adjustment holes 22, the distance between the first frame 1 and the second frame 2 is adjusted.
[0021] Preferably, a gap 4 is provided between the first frame 1 and the second frame 2, and the gap 4 is used to accommodate the main material of the iron tower T. During implementation, the overhead ground wire lifting device can be fixed on the main material of the iron tower T on the top of the suspension clamp.
[0022] In order to increase the fixing effect of the overhead ground wire lifting device and the main material T of the iron tower, a first locking buckle 11 is provided on the first frame 1, and a second locking buckle 21 is provided on the second frame 2. The first locking buckle 11 and the second locking buckle 21 are respectively located on opposite sides of the gap 4. The first locking buckle 11 and the second locking buckle 21 have the same structure, and both are fixing structures for bolts to cooperate with limit blocks. During implementation, the overhead ground wire lifting device is fastened to the main material T of the iron tower by tightening the bolts on the first locking buckle 11 and the second locking buckle 21 respectively.
[0023] It can be understood that by adjusting the locking position between the first frame 1 and the second frame 2 , the size of the gap 4 can be adjusted, and the overhead ground wire lifting device can be fixed at any position of the tower main material T.
[0024] Furthermore, the lifting hook assembly 3 in this embodiment is set as two groups, which are respectively fixed at the ends of the first frame 1 and the second frame 2. The lifting hook assembly 3 includes: a screw rod 31, a connecting piece 32, a lifting hook body 33, a screw rod sleeve 34 and a handle 35 connected to the screw rod sleeve 34.
[0025] During implementation, the screw rod 31, the connecting piece 32 and the lifting hook body 33 are in the shape of a straight rod, the screw rod 31 is adapted to be assembled in the screw rod sleeve 34, and the two screw rod sleeves 34 are rotatably connected to the ends of the first frame 1 and the second frame 2. The lifting hook body 33 is used to hook the wires on the left and right sides of the suspension wire clamp.
[0026] Furthermore, the handle 35 is connected to the screw sleeve 34, and a ratchet structure connected to the screw sleeve 34 is provided inside the handle 35. The function of the handle 35 is to link the screw sleeve 34 with the first frame 1 or the second frame 2 to rotate.
[0027] The handles 35 on the first frame 1 and the second frame 2 are shaken respectively, and the screw sleeves 34 on both sides will rotate along with the rotation of the handles 35 driven by the ratchet mechanism inside the handles 35 .
[0028] As the screw sleeve 34 rotates, the screw 31 moves up and down relative to the screw sleeve 34 under the action of its internal thread. Since the screw 31, the connecting piece 32 and the lifting hook body 33 are connected, the hook body 33 is driven to move up and down, thereby achieving the effect of loosening or tightening the wire inside the suspension clamp. In this process, when the wire loosens the suspension clamp, the suspension clamp can be replaced. After the suspension clamp is replaced, the wire can be tightened to remove the overhead ground wire lifting device. During the adjustment process, the lifting hook body 33 can rotate at a certain angle relative to the connecting piece 32 to adapt to the change in the position of the wire.
[0029] In the specific implementation of the overhead ground wire lifting device of this embodiment, the size of the gap 4 can be adjusted by adjusting the locking position between the first frame 1 and the second frame 2, so that the overhead ground wire lifting device can be fixed at any position of the tower main material T. The handles 35 on the first frame 1 and the second frame 2 are shaken respectively to drive the hook body 33 to move up and down, so as to loosen or tighten the internal wire of the suspension clamp and replace the suspension clamp, thereby solving the problem of no special tools when replacing the suspension clamp, high labor intensity, long time consumption, and much carrying work required during the replacement operation, and further simplifying the operation process to reduce the power outage time caused by the failure of the suspension clamp.
