In order to better understand the utility model, the utility model will be described in detail below in conjunction with specific examples.

In order to avoid the disadvantages of the traditional hoisting method of rope binding and hoisting, the utility model provides a hoisting clamp for overhead line construction with multiple split conductors. The hoisting fixture is mainly made of Q235 steel and needs to be used with wire clamps. When in use, the wire clamp is fixed on the jig, and then the wire is clamped by the wire clamp, so that the one-time lifting of multiple split wire jumpers can be realized. The specific structure of the lifting fixture of the present utility model is stated in detail as follows.

Please refer to FIGS. 1A and 1B , which are schematic diagrams of the structure of a lifting fixture 10 according to a first preferred embodiment of the present invention. The hoisting fixture 10 is mainly in the shape of a disc, and 8 joints 14 for connecting wire clamps are evenly distributed around the main disc 12, that is, the angular interval between every two joints is 45°, and the disc 12 A lifting lug 16 for lifting is welded in the center. The disc 12 can evenly provide circular holes 120 to reduce the weight of the lifting fixture 10 itself. In addition, the pattern of the circular holes is easy to process and beautiful in style. Each connector 14 is provided with a clamp mounting hole 140 for connecting with a wire clamp. A hoisting hole 160 is provided on the lug 16 to facilitate the passage of ropes or other hoisting tools.

Please refer to FIG. 2 , which is a schematic view after the assembly of the lifting fixture 10 and the wire clamp 40 . When in use, firstly install and fix the wire clamp 40 and the corresponding installation hole 140 of the joint 14 through bolts or other fasteners. Then, the wires are fastened with corresponding wire clips 40 . Finally, the lifting lug 16 can be fixed by the lifting tool to lift the whole lifting jig 10, the wire clamp 40 and the wires in the wire clamp 40 together, that is, the lifting jig 10 can successfully lift eight wires together at one time.

Please refer to FIG. 3 and FIG. 4 , which are schematic diagrams of the structure of the hoisting clamp 20 of the second preferred embodiment of the present invention and a schematic diagram of the assembly of the hoisting clamp 20 and the wire clamp 40 . When the wires that need to be hoisted at the same time are six, the hoisting jig 20 in Fig. 3 can be used. The general structure of the lifting jig 20 and the lifting jig 10 is basically the same, including a disc 22 , a joint 24 and a lifting lug 26 . The difference is that the number of joints 24 is six, that is, the angular interval between every two joints 24 is 60°. Similarly, the joints 24 are evenly distributed on the circumference of the disc 22, the lugs 26 are welded in the middle of the disc 22, and the disc 22 evenly offers round holes 220 to reduce the weight of the lifting fixture 20 itself. A clamp installation hole 240 is provided for connecting with the wire clamp 40 , and a lifting hole 260 is provided on the lifting ear 26 to facilitate the passage of a rope or other lifting tools. During use, the hoisting jig 20 is used in the same way as the hoisting jig 10, and six wires can be hoisted simultaneously at one time.

Please refer to FIG. 5 , which is a schematic structural diagram of a lifting clamp 30 according to a third preferred embodiment of the present invention. When there are four wires that need to be hoisted simultaneously, the hoisting jig 30 in Fig. 4 can be used. The general structure of the lifting jig 30 and the lifting jig 10 is basically the same, including a disc 32 , a joint 34 and a lifting lug 36 . The difference is that the number of joints 34 is four, that is, the angular interval between every two joints 34 is 90°. Similarly, the joints 34 are evenly distributed on the circumference of the disc 32, the lugs 36 are welded in the middle of the disc 32, and the disc 32 evenly offers round holes 320 to reduce the weight of the lifting clamp 30 itself. A clamp installation hole 340 is provided for connecting with the wire clamp 40 , and a lifting hole 360 is provided on the lifting ear 36 to facilitate the passage of a rope or other lifting tools.
