After the insulation piercing clamp is fastened, the clamp is separated from the sleeve, and the installation tool can be lowered to complete the unlocking of the insulation piercing clamp and the clamping device, without the need to set a clamp unlocking mechanism on the insulation rod.

As shown in Fig. 8 and Fig. 9, the present invention provides a kind of quick installation tool, comprises the above-described insulation piercing clamp clamping device 100, also includes insulating rod 60, wire hanger device 80, and is arranged on the installation base The striking device 90 on the seat 10 is used to drive the double constant torque bolts of the insulation piercing clamp 70 , wherein the driving sleeve 50 is fixedly installed on the striking device 90 , and its position on the installation base 10 is fixed.

Wherein, the hitting device 90 can use corresponding parts on the traditional quick installation tool, and the structure and usage method of the parts are described in Chinese patent documents CN106785498A and CN206506029U.

As shown in Figures 10 and 14, the wire hanger device includes a first U-shaped wire hanger 801 and a second U-shaped wire hanger 802 arranged in parallel on the installation base 10 at intervals, wherein the first and second U-shaped wire hangers A main wire locking device 810 is provided near the U-shaped opening of the wire hanger for locking the main wire 200 . Below the main wire locking device 810 of the first U-shaped wire hanger 802 is provided a lead wire clamping device 820 for clamping the lead wire.

As shown in Figures 11 and 13, the main wire locking device 810 includes: a deadbolt cover 811, a deadbolt 812, a motor mount 813, a stepping motor 814, a screw 815, a screw nut 816, an elastic element 817, a position limiting Switch 818, and pressing plate 819.

Wherein, the deadbolt cover 811 is connected with the first U-shaped hanger 801 or the second U-shaped wire hanger 802 . The lock tongue 812 is telescopically and slidably disposed in the lock tongue cover 811 , and the lock tongue 812 is provided with a square groove 812 a and a screw nut 816 placed in the square groove.

Wherein, the stepping motor 814 is arranged on the motor mounting seat 813 outside the deadbolt cover, and is drivingly connected with the screw rod 815, wherein the screw rod 815 and the nut 816 form a screw nut kinematic pair. The elastic element 817 is disposed in the lock tongue cover 811 and biased towards the lock tongue 812 so that the lock tongue has a movement tendency to protrude outward.

As shown in Figure 13, the working mechanism of the main wire locking device is as follows: the deadbolt can slide inside the deadbolt cover. A square groove has been opened in the dead bolt, and a screw mandrel and a screw mandrel nut are placed inside. The screw rod is connected with the stepper motor. When the stepper motor rotates, it drives the screw to rotate, and the shape of the screw nut is also square, which is restricted by the square groove of the lock tongue, so the screw nut will not rotate, but translate on the screw.

In the initial state, the screw nut is on the right, and the dead bolt also slides to the right under the action of the dead bolt spring. When the device is to be mounted on the main wire, the main wire will be pressed against the slope of the lock tongue, and the lock bolt will retreat to the left. When the main wire crosses the slope, the lock tongue will slide to the right under the action of the spring to restore the original state. During the wire mounting process, there is no need for manual intervention or electric control.

When the live fire connection operation is completed and needs to be unlocked, the stepping motors on both sides are controlled to rotate through the remote controller, and the screw nut is driven to the left until the limit switch is pressed, and the control circuit stops the stepping motors from rotating.

After the limit switches on both sides were all touched, the control circuit paused for another 3 seconds to keep the maximum state of the deadbolt opening, and now the main wire can exit smoothly. Afterwards, the stepper motor rotates a certain number of steps in the opposite direction to reach the initial position.

In the present invention, no limit switch is needed for the dead bolt to return to the initial position, because the force required when pulling back is very large, and the stepping motor may lose its step, so it is not judged by the number of steps of the stepping motor, but It is judged by whether the limit switch is triggered or not. When the bolt is retracted, the force required is very small, so the step will not be lost, and the steps can be counted directly, which can save the limit switch on the other side, reduce weight and wiring complexity.

As shown in FIG. 14 , the main wire 200 is held by the first U-shaped wire hanger 801 and the second U-shaped wire hanger 802 of the wire hanger device 810 , and the U-shaped opening is closed by the lock tongue 812 of the main wire locking device.

When the branch line needs to be locked, the turning handle connected to the gear is turned to drive the rack to move, so that the movable splint is close to the fixed splint. When the hand is released, the pawl will prevent the gear from turning back and maintain the locking force.

When the live connection is completed and it needs to be unlocked, when the main wire mechanism is unlocked, the branch wires here will also act synchronously. Branch line unlocking is to rely on electromagnet, after electromagnet is energized, withstood ratchet, allows gear to rotate left and right, and the lead wire (branch line) between movable splint and fixed splint can be taken off like this.

As shown in Figure 15, the lead wire 300 is located in the first U-shaped wire rack 801 (not shown in the figure) and the second U-shaped wire rack 802, and is formed by the movable splint and the fixed splint of the lead wire clamping device 820. Clamping rollers 824a and 825a are clamped in place.

When the quick installation tool of the present invention is in use, install the insulation puncture wire clip first, then clamp the lead wire in the lead wire clamping device, and then lift the quick installation tool below the main wire to press the main wire into the wire hanger device In the U-shaped opening of the U-shaped opening, then operate the strike device to make the insulation piercing wire clip pierce the main wire and the lead wire, then the insulation piercing wire clip is combined with the main wire and the lead wire to realize the live fire connection operation, and then unlock the main wire locking device and Lead clamping device, and pull down the quick installation tool to make it out of the insulation piercing clamp and the main wire and lead wire to complete the live fire connection work.
