Detailed Description
As shown in fig. 1, the present utility model includes a butt joint pipe 2, and the butt joint pipe 2 is made of a straight steel pipe. The front pipe wall of the butt joint pipe 2 is circumferentially provided with a plurality of hooks 1, the hooks 1 are made of rigid iron wires, and the hooks 1 extend out of the butt joint pipe 2 and are arranged along the axial direction of the butt joint pipe 2. The hooks 1 in the present embodiment are all roundabout hooks 1, and the bending directions of the hooks 1 are all curved toward the axial direction along the radial direction of the butt joint pipe. In addition, the hook bottoms of the hooks 1 are all conical bottoms, and the free end of each hook 1 is a straight section parallel to the axis of the butt joint pipe 2. The non-free end side of the hook 1, the free end of the hook 1 and the hook base cone of the hook 1 thus all enclose a circle coaxial with the docking tube 2. The diameter of the circle formed by the non-free end side of the hook 1 and coaxial with the butt joint pipe 2 is slightly smaller than the inner diameter of the buried pipeline 4 through which the cable is to be penetrated. In this embodiment, the diameter of the buried pipe 4 is 5mm smaller than the diameter of the cable to be threaded, and the free end of the hook 1 has a straight section parallel to the axis of the butt joint pipe 2. Under the arrangement of the structure, the pipe wall of the buried pipeline 4 through which the cable is to be penetrated can play a role in guiding the utility model, so that the axial direction of the utility model is consistent with the axial direction of the buried pipeline 4 through which the cable is to be penetrated, and the threading tool can smoothly move in the buried pipeline 4.
The utility model is characterized in that the rear end of the butt joint pipe 2 is connected with a nylon joint 3 in a screw way, and the nylon joint 3 is used for connecting one end of a wire rope for assisting threading
The diameter of a circle surrounded by the free ends of the hooks 1 is smaller than the inner diameter of the butt joint pipe 2, so that in the butt joint process of the two threading tools, the butt joint steel pipes 2 of the two threading tools can prop open the hooks 1 on the two butt joint pipes, and the hooks 1 on the two threading tools can be hooked in a crossing manner so as to realize butt joint. The diameter of the circle enclosed by the free ends of the hooks 1 in this embodiment is 5mm smaller than the inner diameter of the docking tube 2.
In addition, the diameter of a circle surrounded by the bottom tip of the hook 1 is larger than the outer diameter of the butt joint pipe 2, so that the hook 1 can be unfolded when the butt joint pipes of two threading tools are in butt joint. The diameter of the circle formed by the non-free end side of the hook 1 is 30mm smaller than the inner diameter of the buried pipeline 4 through which the cable is to be penetrated.
