[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-Figure 4 FIG. 1 shows a first embodiment of the centrifugal grounding clamping device of the present invention.

[0019] The centrifugal grounding clamp clamping device in this embodiment is used to stably connect a grounding clamp movable end 12 connected to the grounding clamp driving member 13 to a grounding clamp fixed end 11 through a grounding clamp driving member 13. The grounding clamp driving member 13 is connected to a driving head 14, and a protrusion 5 is provided on the driving head 14.

[0020] In specific implementation, the grounding clamp 1 includes: a grounding clamp fixed end 11, a grounding clamp movable end 12, a grounding clamp driving member 13 and a driving head 14. The grounding clamp fixed end 11 is hook-shaped and is hooked on a steel-core aluminum stranded wire 3. The bottom of the grounding clamp fixed end 11 is connected to the grounding wire 4. A positioning boss 15 is provided at the bottom of the grounding clamp fixed end 11. The grounding clamp driving member 13 passes through the positioning boss 15 and is meshed and connected with the positioning boss 15.

[0021] In a specific implementation, the grounding clamp driving member 13 is a grounding clamp driving screw, which is rotatably connected to the positioning boss 15, and the top of the grounding clamp driving screw is connected to the grounding clamp movable end 12, and the bottom is connected to the driving head 14. When the driving head 14 is subjected to force and the grounding clamp driving screw is linked to rotate relative to the positioning boss 15, the grounding clamp driving screw drives the grounding clamp movable end 12 to move up and down, and the moving direction is the axial direction of the grounding clamp driving screw.

[0022] The driving head 14 is subjected to force to drive the grounding clamp to drive the screw to rotate, which is achieved by the centrifugal grounding clamp clamping device 2 driving the protrusion 5 on the driving head 14 to rotate.

[0023] The centrifugal grounding clamp clamping device 2 comprises: a clamping base 21, one end of which is provided with an assembly groove 211; two clamping heads 22 installed in the assembly groove 211 and capable of rotating around a fixed rotating shaft respectively, the two clamping heads 22 are arranged opposite to each other, and the two clamping heads 22 have two ends respectively arranged on opposite sides of the fixed rotating shaft, one end of which is provided with a clamping ring 22a for clamping the protrusion 5, and an elastic member is provided between the other opposite ends 22b, and the middle part of the clamping ring 22a is provided with a gap t for the protrusion 5 to pass through, wherein: the clamping ring 22a presses the driving head 14 of the grounding clamp driving member 13, the protrusion 5 on the driving head 14 passes through the gap t, and the protrusion 5 is clamped in the groove body p surrounded by the clamping ring 22a and the end of the clamping base 21.

[0024] The clamping base 21 is made of 6061 aluminum alloy and is manufactured by a milling machine.

[0025] It further includes: a glass fiber insulation rod 25 clamped and connected to the clamping base 21 , the glass fiber insulation rod 25 is a 36 mm glass fiber insulation rod, which is sleeved on one end of the clamping base 21 .

[0026] Furthermore, the structures of the two clamping heads 22 are symmetrical, and the two half rings at the top form a clamping ring 22a. That is, the clamping ring 22a in this embodiment is configured as two petals, and the two petals of the clamping ring 22a can be rotated around the fixed rotation axis O to open, and the elastic member 23 allows the two petals of the clamping ring 22a to rotate around the fixed rotation axis O and then return to their original position. The elastic member 23 is a spring in this embodiment.

[0027] Preferably, the two opposite ends of any petal retaining ring 22a are respectively provided with inclined surfaces m for allowing the protrusion 5 on the driving head 14 to slide into or out of the gap t. The inclined surfaces m in this embodiment are 45-degree grooves on the two petal retaining rings 22a.

[0028] Furthermore, the fixed rotation axis O includes: a first pin hole 212 provided at one end of the clamping base 21; a first positioning block 22c provided in the middle of the clamping head 22, and a second pin hole 222 provided on the first positioning block 22c; and a plurality of latches 24, wherein: the latches 24 are sequentially passed through the first pin hole 212 and the second pin hole 222 for fastening. The two clamping heads 22 can be respectively rotated to open or reset relative to the clamping base 21 with the latches 24 as the rotation axis.

[0029] Preferably, the first positioning block 22 c is arc-shaped, and the latch pins 24 are respectively inserted into the second pin holes 222 of the first positioning block 22 c from opposite sides of the clamping base 21 .

[0030] When the centrifugal grounding clamp clamping device of the present invention is implemented, the two clamping heads 22 of the centrifugal grounding clamp clamp are connected with the grounding clamp driving member 13 from the bottom, and the two clamping rings 22a press the driving head 14 of the grounding clamp driving member 13. The protrusion 5 on the driving head 14 passes through the gap t, and the protrusion 5 is clamped in the groove body p surrounded by the clamping ring 22a and the end of the clamping base 21. That is to say, the two clamping rings 22a are in contact with the protrusion 5 on the driving head 14. During this process, the two clamping heads 22 can be rotated and opened relative to the clamping base 21 with the pin 24 as the rotating axis, and the protrusion 5 pushes the two clamping rings 22a open; after the protrusion 5 on the driving head 14 passes through the gap t, the elastic member 23 causes the two petals of the clamping ring 22a to rotate around the fixed rotating axis O and then reset, and the protrusion 5 is clamped in the groove body p surrounded by the clamping ring 22a and the end of the clamping base 21.

[0031] After the protrusion 5 on the driving head 14 is fixed, the clamping force of the centrifugal grounding clamp holder is 50 Newtons. When the staff starts the motor to drive the glass fiber insulating rod 25, the two clamping heads 22 are subjected to the centrifugal force to further clamp the grounding clamp movable end 12; when the speed reaches 600RPM, the clamping force increases to 200 Newtons, which can ensure that the grounding clamp holder and the grounding clamp movable end 12 are not separated during the working process. When the staff turns off the motor, the centrifugal force on the two clamping heads 22 disappears, and the clamping force of the centrifugal grounding clamp holder is restored to 50 Newtons, and the staff can easily separate the centrifugal grounding clamp holder from the grounding clamp movable end 12.

[0032] The implementation of the centrifugal grounding clamp clamping device of the present invention has the following beneficial effects: the centrifugal grounding clamp clamping device comprises: a clamping base, one end of which is provided with an assembly groove; two clamping heads installed in the assembly groove and capable of rotating around a fixed rotating shaft respectively, the two clamping heads are arranged opposite to each other, and the two clamping heads have two end portions respectively arranged on opposite sides of the fixed rotating shaft, one end of which is provided with a clamping ring for clamping a protrusion, and an elastic member is provided between the other opposite end portions, and the middle part of the clamping ring is provided with a gap for the protrusion to pass through, wherein: the clamping ring presses against the driving head of the grounding clamp driving member, the protrusion on the driving head passes through the gap, and the protrusion is clamped in the groove body surrounded by the clamping ring and the end of the clamping base, which can increase the clamping force so that the insulating rod does not separate from the grounding clamp during rotation; the structural arrangement is more compact and delicate, which is conducive to assembly.
