Detailed ways

As shown in Fig. 1 and Fig. 2, a kind of new wire starting device of the utility model comprises: fixed pulley mechanism 1, movable pulley mechanism 2 and traction line 3, and described fixed pulley mechanism 1 comprises fixed pulley 4, fixed shaft 5, base 6. The support rod 7, the fixed shaft 5 passes through the shaft hole of the fixed pulley 4 and extends to both ends;

The base 6 is a detachable ring structure, the inner edge of the base 6 is in contact with the utility pole, and the base 6 is fixed on the top of the utility pole by fastening bolts;

A pair of support rods 7 are vertically arranged on the outer edge of the base 6, and the extension ends of the support rods 7 are provided with movable shaft holes, and the two ends of the fixed shaft 5 are inserted into the movable shaft holes;

Both ends of the fixed shaft 5 are also connected with a fixed table 8 through an extension rod;

The moving pulley mechanism 2 comprises a moving pulley 9, a wire clamp groove 10, and a wire starting pin 11, and the rotating shaft of the moving pulley 9 extends downwards to be provided with a wire clamp groove 10, and the wire starting clamp groove 10 connects the wire starting pin 11 Clamping and fixing, the starting pin 11 is connected and fixed with one end of the starting cable;

One end of the traction line 3 is provided with a pulling handle, and the other end of the traction line 3 is used as an extension end, and after passing through the upper edge of the fixed pulley 4 and the lower edge of the movable pulley 9, it extends upward to the fixed table 8 and is fixed.

The support rod 7 and the base 6 are connected as a whole by welding, and an angle iron 12 is also arranged between the support rod 7 and the base 6 .

The inner edge of the base 6 is also provided with rubber and brushes.

The size of the starting pin 11 is adapted to the size of the insulator threading hole provided on the utility pole.

The pulling wire 3 is an insulated nylon rope.

The utility model uses a set of pulleys to transfer the staff who start the line to the ground, which reduces the force of starting the line, reduces the work intensity, and improves the safety factor of the line starting operation; the fixed pulley 4 and the movable pulley 9 are both Made of engineering plastics, the central shaft is fully lubricated, and the inner edge of the pulley has a large friction coefficient to avoid slipping during the rope pulling process. The entire pulley block requires a low moment of inertia to facilitate precise operation.

When the utility model is in use, the worker is first required to climb up the utility pole to install the starting device on the top of the utility pole. During the specific operation, the disassembled ring base is first installed and fixed with bolts, and then the fixed pulleys are installed in turn. 4, extension bar, fixed table 8; this moment, one end of traction wire 3 is tied on the fixed table 8, and the other end of described traction wire 3 leaves enough long length to pass through the rotating shaft bottom of movable pulley 9 successively, fixed pulley After the top of 4, extend the traction line 3 to the ground and connect the pull handle; then vertically install the wire clamp groove 10 below the movable pulley 9, and the wire clamp groove 10 is an adjustable mechanism; finally install the wire pin 11 At one end of the starting cable, the starting pin 11 is passed through the starting clamp groove 10, and now the starting clamp groove 10 is adjusted to clamp the starting pin 11 to complete fixing.
