Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

Fig. 1-3 a supplementary reposition of redundant personnel line of portable aims at providing a convenient installation formula reposition of redundant personnel line that replaces traditional reposition of redundant personnel line. This device has become an annealed copper line that both ends are Y shape forked annealed copper line with an annealed copper line, adopts the annealed copper line that the cross-sectional area is 35 square millimeters (or 70 square millimeters) as the main part, and both ends Y word divides the fork, erection joint and back-up fastener structure, realizes that the shunting line is high-efficient, swift, safe fixed. The specific structure, principle and operation flow are as follows.

The two ends of the main body line of the annealed copper wire 1 are respectively connected with a first joint 2 and a second joint 3. A group of bifurcate thread ends 4 are lapped at two ends of the annealed copper wire 1, so that two Y-shaped structures are formed. The end surface of the forked wire head 4 is connected with a back-up wire clamp 5.

The first joint 2 and the second joint 3 are identical in structure and, as shown in fig. 2, are each composed of a fixed joint 6 and a movable joint 7. The fixed joint 6 is divided into three parts according to the position structure, namely an arc part, a longitudinal part and a transverse part. The longitudinal portion is provided with a guide groove 601, and the guide groove 601 is engaged with the slider 701 on the movable joint 7. The transverse part is provided with a movably nested screw 8, one end of the screw 8 is movably arranged on the movable joint 7, and the other end of the screw 8 is provided with a rotating handle 9. When the screw 8 rotates, the movable joint 7 can be raised or lowered with respect to the fixed joint 6. During the use, the arc portion of first joint 2 articulates on the power transmission line, and rotatory turning handle 9 for the distance between activity joint 7 and the fixed joint 6 reduces, and then with the transmission line joint between activity joint 7 and the fixed joint 6. After the first joint 2 is fixed, the fixing pin 10 installed at the transverse part is rotated, so that the fixing pin is abutted against the screw rod 8, and the screw rod 8 is kept stable and is not loosened.

The second connector 3 is used for clamping the shunt line, and the clamping mode is the same as that of the first connector 2.

Two back-up wire clamps 5 are installed corresponding to the first connector 2 and the second connector 3 which are at the same position, namely the first connector 2 and the back-up wire clamp 5 corresponding to the first connector are butted on a transmission line, and the second connector 3 and the back-up wire clamp 5 corresponding to the second connector are butted on a shunt line. The function of the back-up wire clamp 5 is to assist in fixing and transferring, and to prevent the first connector 2 and the second connector 3 from overheating.
