The pneumatic motor 1041, with an intake pressure of 4-6 kg / cm² and a torque of 60 Nm, provides the power source for the hook's rotation. The motor mount (lower) 1042 is secured to the gripper's upper bracket 1012 with four M4 screws and to the motor mount (upper) 1043 with two M4 screws. The small bearing 1046 nests within the small bearing support 1045, with the two working together to axially secure the small rotating shaft 1044. The small gear 1047 is secured to the gear end face of the small rotating shaft 1044, secured axially with a small circlip 1049 and radially with a small key 1048. The small rotating shaft 1044 has a keyway for the small key 1048, and a hexagonal head is machined on the shaft end to connect to the pneumatic motor 1041, enabling rotational torque transmission. The bearing support (large) 10411 is connected to the bearing (large) 10412 and axially fixes the rotating shaft (large) 10410 with the bearing (large) 10412 at the end of the wire clamp fixing frame 1014. The gear (large) 10413, flat key (large) 10414, and elastic retaining ring (large) 10415 are installed on the rotating shaft (large) 10410 to respectively realize the transmission of small torque to large torque and the tangential and axial fixation of the gear (large) 10410. The rotating shaft (large) 10410 has a central cross hole for accommodating the hook claw 102 and the hook ring screw 304 respectively. The cross side wall realizes the rotation of the wire clamp screw, and the sliding mechanism 103 realizes the closure of the movable hook claw 1024.

[0079] A preferred embodiment provides a preferred structure of hook 102. As shown in FIG8 , hook 102 comprises a pull rod 1021, hook (upper) 1022, hook (lower) 1023, a movable hook 1024, a hook fixing rod 1025, and a pressure spring 1026. The hook (upper) 1022 and hook (lower) 1023 form the hook body, connected by concave-convex grooves on both sides. The movable hook 1024 is installed in the middle and fixed to the two hook fixing rods 1025. The pressure spring is installed in the middle arc groove. The end of the hook (lower) 1023 has a left-hand threaded hole, which connects to the left-hand thread at the front end of the pull rod 1021. It is used to connect to the sliding mechanism 103 through a thrust bearing 1035, achieving decoupling of the two degrees of freedom of rotation and sliding.

[0080] In some implementations, the operation process of closing and opening the claw 102 is provided. Specifically, the claw 102 is driven by air pressure provided by an air compressor on the work platform, which drives the translational cylinder on the wire clamp gripper to achieve translational movement of the claw 102. The claw 102 closes and opens under the restraint of the wire clamp holder 1014. The robot issues commands, and the electromagnetic on the work platform performs corresponding actions, changing the direction of the gas thrust, thereby driving the cylinder on the wire clamp gripper to move. The cylinder is located on 103.

As shown in FIG9 , the wire clamp fixing mechanism 200 includes a fixed base 201 and a fixed shell 202. The lower surface of the fixed base 201 is used to connect with the cross arm, and the upper surface is connected to the fixed shell 202 by six screws. The fixed shell 202 is mainly used for waterproofing and dustproofing. This wire clamp fixing mechanism realizes the fixing and posture initialization of the wire clamp, which facilitates the rapid grasping of the robot.

The upper base plate 2012 and lower base plate 2011 are secured by screws, encapsulating and securing the entire switch mechanism. The drain wire adjustment block 2013 is an adjustable component that can be replaced to accommodate different cable diameters. It works in conjunction with the sidewall of the drain wire fixing block 2014 to secure the drain wire. A first spring is positioned toward the push rod 2015, ensuring that the drain wire fixing block 2014 is always positioned rightward. A second spring is also positioned toward the fixture switch 2016. Below the drain wire fixing block 2014 is an open groove, the same size as the fixture switch 2016. Above the fixture switch 2016 is also an open groove within which the drain wire fixing block 2014 moves. Pushing the push rod 2015 drives the drain wire fixing block 2014. When the drain wire fixing block 2014 reaches the inner opening of the groove, the fixture switch 2016 springs open under the pressure of the second spring, closing the wire clamp mechanism.

[0082] As shown in Figure 10(c), the housing switch rod 2017 is connected to the switch pin hole 2025 of the fixing device. It is displaced with the housing opening 2026 of the housing (left) 2021 to enable the housing to be opened and closed. The housing (center) 2022 has shaft connection holes and torsion spring mounting holes on the left and right sides for connecting and securing the housings (left) 2021 and (right) 2023. The lower surface of the housing (left) 2021 is provided with a housing switch hole that cooperates with the housing switch rod 217 to enable the device to be opened and closed. The right inner groove connects to the left protrusion of the housing (right), allowing the left and right doors to intersect. When closed, the housing switch rod 217 can secure the two doors, as shown in Figure 10(b). Both doors are equipped with door handles for easy gripping and an "I"-shaped opening for securing the position of the wire clamp hook screw 304.

[0083] In a preferred embodiment of the present invention, a preferred structure of a wire clamp body 300 is provided. As shown in FIG12 , the wire clamp body 300 includes: a wire clamp body structure 301, a drain wire fixing block 302, a fastener 303, a hook and ring screw 304, and a drain wire 305. The drain wire 305 is clamped by the fastener 303, pushing the drain wire fixing block 302 to cooperate with the wire clamp body structure 301, and is installed manually. The hook and ring screw 304 is connected to another drain wire fixing block 302, and is used for the wire clamp gripper 100 to grab and connect to the live cable to complete the drainage operation. The fastener 303 can be a hexagonal screw or the like.

[0084] In a preferred embodiment of the present invention, a preferred configuration of a work platform 400 is provided. The work platform 400, as a specific electrical device for a wire clamp gripper, comprises, as shown in FIG13 , a compressor 401, a pressure regulating valve 402, a center-through, three-position, five-way solenoid valve 403, and a normally closed, two-position, two-way solenoid valve 404.
