Detailed ways

As shown in Figures 1 and 2, the remote control electric tackle includes a box body 1, which is provided with a drive pulley 2 that can be hung on the ground wire, and the two ends of the drive pulley installation shaft 21 are installed on the pulley bracket 4 through bearings , The pulley bracket 4 is fixed on the box body 1. Anti-friction bearings 12 are provided between the two sides of the driving pulley 2 and the pulley bracket 4 .

One end of the drive pulley mounting shaft 21 stretches out from the pulley bracket 4, and is coaxial with the output shaft of the gearbox 6, and the input end of the gearbox 6 is connected with the output end of the drive motor 5. The driving motor 5 is fixed on the casing 1 through a motor bracket 9 .

The driving motor 5 is electrically connected with the storage battery 7 and the remote control signal receiving module 8 mounted on the box to form a control loop.

Just below the drive pulley 2 is provided with a tension pulley 3 that cooperates with it. A bearing is arranged between the tension pulley 3 and the tension pulley mounting shaft 31. One end of tensioner pulley installation shaft 31 stretches out pulley support 4, and this end is connected with an end of lever type control rod 10, and the fulcrum of control rod 10 is fixed on the pulley support 4. The control rod 10 can control the tension pulley mounting shaft 31 to move up and down. The pulley bracket 4 is provided with a chute 41 that can move up and down the tension pulley mounting shaft 31 . The other end of the control rod 10 is provided with a plurality of positioning locking holes 101, and the positioning locking holes are arranged along the axial direction of the control rod. The pulley bracket 4 is provided with a positioning locking hook 11, which cooperates with the positioning locking hole 101 to realize the positioning locking of the control rod 10, thereby positioning the tensioning pulley 3. Also be provided with anti-friction bearing 13 between tension pulley 3 side and pulley support 4.

The pulley bracket 4 is provided with an opening 42 that can be snapped into the ground wire. The position of the opening 42 corresponds to the gap between the drive pulley 2 and the tension pulley 3, and is arranged parallel to the radial direction of the two pulleys.

The casing is provided with a traction rope connecting ring 14 .

The anti-fall bar 15 is Shape, one end of which is fixed on one side of the top surface of the box 1; the other end is connected to the bottom of the side of the box 1. Form an airtight rectangular frame with the "L" shaped box body 1. Thereby, after the ground wire can be prevented from slipping out from between the two pulleys, the tackle will fall from the ground wire. The anti-fall bar 15 is a detachable type.

When erecting the special optical cable, first transport the tackle to the working position of the operator on the pole tower with a pulley. Then use a kind of independent safety belt one end to be fixed on the pole tower, and the safety belt other end is hung on casing 1 safety belt fixing ring 16 by hook and prevents whole tackle from falling. Open anti-falling bar 15, after anti-falling bar 15 is hung on ground wire, it is fixedly connected with casing again, and tackle promptly hangs on ground line like this. Tackle is passed ground wire antivibration hammer again, and ground wire is snapped in the wheel groove of driving pulley 2 along the opening 42 of pulley support, and is fixedly connected between falling bar 15 and the casing immediately. Simultaneously operate the control lever 10, the control lever 10 lifts the tension pulley installation shaft 31, the tension pulley 3 rises, and the ground wire is squeezed tightly in the wheel grooves of the two pulleys. Then the positioning locking hook 11 is hung on the corresponding positioning locking hole on the control rod 10 to realize the positioning of the tension pulley 3 . Finally, the traction rope that is connected on the special optical cable is bolted on the traction rope connecting ring 14, and the installation work is completed.

After the installation is completed, the remote controller can be used to send the start signal, and the remote control signal receiving module 8 receives the signal, controls the drive motor 5 to connect with the storage battery 7, and drives the pulley 2 to rotate. Because the driving pulley 2 and the tensioning pulley 3 are very tight to squeeze and block the ground wire, there is enough friction between the driving pulley 2 and the ground wire to ensure that the driving pulley 2 rolls on the ground wire without slipping. The driving pulley drives the block to advance on the ground line like this, and the traction rope is brought to the other side pole tower by one side pole tower. Then the remote controller sends an instruction, and the remote control signal receiving module 8 controls the drive motor 5 to disconnect from the storage battery 7, and the tackle stops running.

After erecting optical cable completion, when this tackle was removed from the ground wire, at first hook the box safety belt fixing ring 16 with the safety belt and the tackle is fixed on the pole tower. Then remove the traction rope connected to the optical cable, put it on the installed pulley, and fix it on the tower to prevent the traction rope from falling off. Then the positioning locking hook 11 is disengaged from the positioning locking hole 101, so that the tension pulley 3 is moved down. The driving pulley 2 is then moved down from the ground wire and the ground wire is pulled out through the opening 42 . Finally, the anti-fall bar 15 is opened and the tackle is taken off from the overhead ground wire, that is, the dismantling is completed.

The traction rope should use a special reel to prevent the traction rope from getting wet and damaged when it falls to the ground.

Wherein, according to the common sense in this technical field, the two ends of the tensioning pulley installation shaft 31 can pass through the both sides of the pulley bracket 4 respectively, and the pulley bracket is provided with two chute, and both ends of the tensioning pulley installation shaft 31 are provided with One control rod, two control rods are connected with a total operating handle. In this way, when the mounting shaft of the tensioning pulley moves up and down, both ends of the shaft are simultaneously lifted or dropped by force, which is more stable.

The utility model is not limited to the above-mentioned embodiments.
