As shown in fig. 8 and 9, the present invention provides a quick installation tool, comprising the above-described insulating puncture clamp holding apparatus 100, further comprising an insulating rod 60, a wire hanger apparatus 80, and a striking apparatus 90 provided on the installation base 10 for driving a double torque bolt of the insulating puncture clamp 70, wherein the driving sleeve 50 is fixedly installed on the striking apparatus 90, and is fixed in position on the installation base 10.
The striking device 90 may use corresponding components on a conventional quick-install tool, the construction and method of use of which are described in chinese patent documents CN106785498A and CN206506029U, respectively.
As shown in fig. 10 and 14, the wire hanger device includes a first U-shaped wire hanger 801 and a second U-shaped wire hanger 802 disposed on the mounting base 10 in parallel at intervals, wherein main wire locking devices 810 are provided at positions of the first and second U-shaped wire hangers near the U-shaped opening for locking the main wires 200. A lead clamping device 820 is provided below the main wire locking device 810 of the first U-shaped hanging wire rack 802 for clamping the lead.
As shown in fig. 11 and 13, the main wire locking device 810 includes: a latch cover 811, a latch 812, a motor mount 813, a stepper motor 814, a lead screw 815, a lead screw nut 816, a resilient element 817, a limit switch 818, and a platen 819.
The latch cover 811 is connected to the first U-shaped hanger 801 or the second U-shaped hanger 802. The lock tongue 812 is telescopically and slidably arranged in the lock tongue cover 811, and a square groove 812a and a screw nut 816 arranged in the square groove are formed in the lock tongue 812.
The stepping motor 814 is arranged on a motor mounting seat 813 outside the lock tongue cover and is in driving connection with a screw rod 815, wherein the screw rod 815 and the nut 816 form a screw rod nut kinematic pair. A resilient element 817 is disposed in the latch housing 811 and biases the latch 812 to have a tendency to move outwardly.
As shown in fig. 13, the main wire locking device operates as follows: the locking bolt may slide within the bolt housing. The lock tongue is internally provided with a square groove, and a screw rod nut are arranged in the square groove. The screw rod is connected with the stepping motor. When the stepping motor rotates, the screw rod is driven to rotate, the shape of the screw rod nut is square and is limited by the square groove of the lock tongue, so that the screw rod nut does not rotate but translates on the screw rod.
In the initial state, the screw nut is on the right, and the lock tongue also slides to the right under the action of the lock tongue spring. When the device is to be mounted on the main conductor, the main conductor can be pressed to the inclined plane of the lock tongue, the lock tongue can retreat to the left, and when the main conductor passes over the inclined plane, the lock tongue slides to the right under the action of the spring, so that the original state is restored. In the wire mounting process, manual intervention and electric control are not needed.
When the electrified fire connection operation is completed and unlocking is needed, the stepping motors on the two sides are controlled to rotate through the remote controller, the screw rod nut is driven to the left until the limit switch is pressed, and the control circuit stops the rotation of the stepping motors.
When the limit switches on the two sides are triggered, the control circuit pauses for 3 seconds, the maximum state of the opening of the lock tongue is maintained, and the main lead can smoothly withdraw. Then, the stepping motor rotates in the opposite direction for a certain number of steps to reach the initial position.
In the invention, the lock tongue is returned to the initial position without a limit switch, and the stepping motor is possibly out of step because the force required by the lock tongue in the back pulling process is large, so the lock tongue is not judged by the running step number of the stepping motor, but is judged by whether the limit switch is triggered or not. When the lock tongue retreats, the required force is small, so that the lock tongue cannot step out, and the lock tongue can directly count steps, so that a limit switch on the other side can be omitted, and the weight and the wiring complexity are reduced.
As shown in fig. 14, the main wire 200 is held by a first U-shaped hanger 801 and a second U-shaped hanger 802 of a wire hanger device 810, and the U-shaped opening is closed by a locking tongue 812 of the main wire locking device.

When the fixed clamp plate 824 moves, the guide rod 822 and the movable clamp plate 825 move together, and the limiting plates 821 are disposed at both sides of the guide rod 822 to limit the moving range of the fixed clamp plate 824, and the first elastic member 823a biases the fixed clamp plate so that the fixed clamp plate has a tendency to be away from the limiting plates.
The movable clamp 825 is slidably disposed on the guide 822, and the fixed clamp and the movable clamp are disposed opposite to each other for clamping the lead. The elastic member 823b is biased toward the movable clamp plate so that the movable clamp plate has a tendency to move away from the fixed clamp plate.

The rotating handle is used for driving the movable clamping plate to be close to the fixed clamping plate.
Wherein the pawl 829a is engaged with the gear 827 under the bias of the pawl spring 829c, allowing the gear to rotate in a forward direction and preventing the gear from rotating. Electromagnet 829b, when energized, activates a pawl, unlocking the pawl from engagement with the gear, allowing the gear to rotate.
Wherein the pawl 829a and electromagnet 829b constitute an electromagnetic unlocking mechanism for locking the reversal of the gear and unlocking upon energization.
The working mechanism of the lead clamping mechanism is as follows:
a pair of clamping rollers 824a and 825a are provided on the movable and stationary clamping plates, respectively. When the branch line is required to be locked, the rotating handle connected to the gear is rotated to drive the rack to move, so that the movable clamping plate is close to the fixed clamping plate. When the hand is loosened, the pawl can prevent the gear from rotating backwards, and the locking force is kept.
When the electrified ignition is completed and unlocking is needed, the main wire guide mechanism is unlocked, and the branch wires act synchronously. The branch unlocking is realized by an electromagnet, and after the electromagnet is electrified, the pawl is propped against, so that the gear can rotate left and right, and a lead (branch) between the movable clamping plate and the fixed clamping plate can be taken down.
As shown in fig. 15, the wire 300 is positioned in a first U-shaped wire hanger 801 (not shown) and a second U-shaped wire hanger 802, and is held in place by holding rollers 824a and 825a on movable and fixed jaws of a wire holding device 820.
