[0025] As a preferred example of the above embodiment, the two main swing arms 31 are L-shaped metal arms, the horizontal section is welded to the main swing ring 32, the end of the vertical section is bent 90 degrees to form a main bending portion, and the main bending portion is deflected 30 degrees toward the crossbar 1, the two main bending portions are distributed in parallel, and a steering gear 5 mounting groove is provided in the middle of the horizontal section of the main swing arm 31; The two auxiliary swing arms 21 are L-shaped arms, the horizontal section is welded to the auxiliary swing ring 22, the end of the vertical section is bent 90 degrees to form an auxiliary bending portion, and the auxiliary bending portion is deflected 30 degrees toward the crossbar 1, the two auxiliary bending portions are distributed in parallel, and the horizontal section of the auxiliary swing ring 22 is provided with a rotating seat 7 at two-thirds of the auxiliary swing ring 22; The main bending portion and the auxiliary bending portion are respectively located at the front and rear sides of the wire clamp body 4, and form a cross-engaging structure when closed.

[0026] As a preferred example of the above embodiment, the servo 5 is embedded in the mounting groove of the horizontal section of the main swing arm 31 and fixed by bolts; the first end of the first connecting rod 6 of the output shaft of the servo 5 is fixedly connected, the second end of the first connecting rod 6 is connected to the second connecting rod 17 through a pin 16, and the second end of the second connecting rod 17 is hinged to the rotating seat 7 of the auxiliary swing arm 21 to form a two-link mechanism, thereby realizing the synchronous opening and closing of the main swing frame 3 and the auxiliary swing frame 2.

[0027] As a preferred example of the above embodiment, the support block 8 is made of elastic material, and the top surface is an arc-shaped groove, and the curvature radius of the arc-shaped groove matches the grounding hanging ring cross bar 1, which is 10-15 mm.

[0028] As a preferred example of the above embodiment, two hooks 11 are provided on the wire clamp body 4 , and the main insulating rope 9 and the auxiliary insulating rope 10 are fixedly connected to the two hooks 11 respectively.

[0029] As a preferred example of the above embodiment, the hook 11 is fixedly arranged on the counterweight 42 .

[0030] As a preferred example of the above embodiment, the width of the counterweight block 42 is greater than the diameter of the connecting column 41 , so as to facilitate the insulating rope to pass over the connecting column 41 .

[0031] As a preferred example of the above embodiment, a hole is formed on the hook 11, and the end of the insulating rope is passed through the hole and then tied and fixed.

[0032] As a preferred example of the above embodiment, a limiting column 12 is provided on the wire clamp body 4, and the position of the limiting column 12 corresponds to the position of the hook 11. The limiting column 12 is provided with a groove for the insulating rope to pass through, thereby limiting the position of the insulating rope and preventing it from being offset or entangled during operation, thereby affecting the opening and closing action of the swing frame.

[0033] As a preferred example of the above embodiment, the insulating rope is made of high-strength, wear-resistant and corrosion-resistant fiber material, such as nylon or polyester fiber, with a moderate diameter for easy grip and pulling; and a length long enough to ensure that the operator can operate the wire clamp body 4 within a safe distance.

[0034] As a preferred example of the above embodiment, the annular groove is replaced by an arc groove, and the curvature is determined according to the actual opening and closing angle. A protrusion that can slide in the arc groove is provided on the main swing ring 32 and the auxiliary swing ring 22. When the remote control servo 5 is started and drives the connecting rod mechanism, the main swing frame 3 and the auxiliary swing frame 2 start to open and close synchronously, and the protrusion slides along the semi-annular groove to ensure that the opening and closing angle does not exceed the curvature range of the semi-annular groove. When the swing frame reaches the predetermined opening and closing angle, the end of the semi-annular groove will prevent the swing frame from continuing to open and close, thereby achieving angle limitation.

[0035] When in use, in the initial state, the angle between the main swing frame 3 and the auxiliary swing frame 2 is the largest, and the swing frame is in an open state as a whole. The insulating rope is passed over the cross bar 1 on the external grounding wire ring, and the insulating rope is pulled to make the wire clamp body 4 rise, so that the support block 8 is against the cross bar 1, and then the remote control steering engine 5 is started to drive the first connecting rod 6 to rotate. The second end of the first connecting rod 6 is connected to the first end of the second connecting rod 17 through the pin shaft 16, so that the first connecting rod 6 drives the second connecting rod 17 to swing when rotating. The pin shaft 16 serves as a hinge point to ensure that the relative movement between the two connecting rods is flat. The second end of the second connecting rod 17 is rotatably connected to the rotating seat 7 on the auxiliary swing frame 2. When the second connecting rod 17 swings, it pushes the rotating seat 7 to make the main swing frame 3 and the auxiliary swing frame 2 rotate outward in opposite directions, thereby achieving the action of clamping the grounding hanging ring cross bar 1; after the operation is completed, the operator remotely controls the servo 5 on the ground to start the drive of the servo 5, so that the main swing frame 3 and the auxiliary swing frame 2 rotate inward in opposite directions, thereby achieving the action of releasing the grounding hanging ring cross bar 1. At this time, the operator slowly loosens the insulating rope to let the wire clamp body 4 fall naturally.

[0036] Example 2 Embodiment 2 As a preferred embodiment of the present invention, Figure 5 As shown, the connecting column 41 is provided with two annular grooves, corresponding to the main swing ring 32 and the auxiliary swing ring 22 respectively. A limiting ring 13 is provided on the inner wall of the main swing ring 32, and a limiting ring 13 is provided on the inner wall of the auxiliary swing ring 22. The width of the limiting ring 13 is greater than the width of the main swing ring 32. A limiting groove is provided in the annular groove corresponding to the position of the limiting ring 13, and a gap is provided between the limiting ring 13 and the annular groove.

[0037] As a preferred example of the above embodiment, a plurality of balls 14 are arranged in the gap to make the rotation smoother.

[0038] As a preferred example of the above embodiment, a wear-resistant pad 15 is arranged in the annular groove to reduce the wear caused by friction and extend the service life of the connecting piece.

[0039] When in use, the main swing ring 32 and the auxiliary swing ring 22 rotate along the annular groove to avoid displacement.

[0041] As a preferred example of the above embodiment, the auxiliary swing ring 22 and the connecting column 41 are connected by welding.

[0042] As a preferred example of the above embodiment, the two auxiliary swing arms 21 are directly connected to the connecting column 41 by welding, and the design of the auxiliary connecting ring is eliminated.

[0043] When in use, the rotation of the servo 5 is transmitted to the second connecting rod 17 through the first connecting rod 6, thereby driving the auxiliary swing frame 2 to rotate relative to the main swing frame 3. Since the main swing ring 32 is rotatable, the auxiliary swing frame 2 is fixed, and the main swing frame 3 will rotate around the connecting column 41 to achieve the opening and closing action.

[0044] Example 4 Embodiment 4 As a preferred embodiment of the present invention, a ground clamp that can be installed and removed on the ground is provided, comprising: The wire clamp body 4 includes a connecting column 41, and a supporting block 8 is arranged on the top of the connecting column 41; A swing frame, the swing frame is composed of a main swing frame 3 and a secondary swing frame 2, the main swing frame 3 is fixedly arranged on a connecting column 41, the secondary swing frame 2 is rotatably arranged on the connecting column 41, the main swing frame 3 rotates and fixes the secondary swing frame 2 to clamp and fix the crossbar 1 of the grounding hanging ring, the main swing frame 3 includes a main swing ring 32 and two main swing arms 31, the two main swing arms 31 are fixedly connected to the main swing ring 32, the main swing ring 32 is fixedly connected to the connecting column 41, the secondary swing frame 2 includes a secondary swing ring 22 and two secondary swing arms 21, the two secondary swing arms 21 are fixedly connected to the secondary swing ring 22, and the secondary swing ring 22 is rotatably connected to the connecting column 41; The connecting rods include a first connecting rod 6 and a second connecting rod 17, which are arranged on the swing frame and used to control the opening and closing of the swing frame; The insulating rope is arranged on the wire clamp body 4 and is used for pulling the wire clamp body 4 .

[0045] As a preferred example of the above embodiment, the main swing ring 32 and the connecting column 41 are connected by welding.

[0046] As a preferred example of the above embodiment, the two main swing arms 31 are directly connected to the connecting column 41 by welding, and the design of the main connecting ring is eliminated.

[0047] When in use, the rotation of the servo 5 is transmitted to the second connecting rod 17 through the first connecting rod 6, thereby driving the auxiliary swing frame 2 to rotate relative to the main swing frame 3. Since the main swing ring 32 is rotatable, the auxiliary swing frame 2 is fixed, and the main swing frame 3 will rotate around the connecting column 41 to achieve an opening and closing action, thereby avoiding the main swing frame 3 and the auxiliary swing frame 2 from rotating at the same time, ensuring the angle between the rotating seat 7 and the insulating rope, and avoiding the main swing frame 3 and the auxiliary swing frame 2 from rotating to the insulating rope position to affect the normal pulling action.

[0048] Example 6 The present invention also provides a method for a ground-mounted and detachable gripping grounding wire clamp, and the specific operation steps are as follows: The operator stands in a safe position on the ground and throws the insulating rope by hand or pulls it over the grounding wire ring crossbar 1 to be installed; The operator slowly pulls the insulating rope to make the wire clamp body 4 gradually approach the crossbar 1; When the top of the wire clamp body 4 lightly touches the crossbar 1, the pulling is stopped, and the operator fine-tunes the steering gear 5 through the remote control to put the swing frame in a half-open state; The operator triggers the clamping command on the remote control, the steering gear 5 starts, and drives the swing frame to merge through the connecting rod; The operator controls the steering gear 5 to reverse, so that the swing frame gradually opens; After ensuring that the swing frame is fully opened and does not cause any obstruction to the crossbar 1, slowly loosen the insulating rope to allow the wire clamp body 4 to fall naturally.

[0049] As a preferred example of the above embodiment, after the swing frame is combined with the clamping cross bar 1, the operator can use the hook 11 to additionally fix the insulating rope to prevent it from accidentally falling off.
