The cleat 100 includes a cleat body 101 and a movable lower pressure plate 102 embedded in the cleat body 101. The clamp plate main body 101 includes a top plate and a bottom plate which are arranged in parallel from top to bottom, and a side plate vertically connected between the same ends of the top plate and the bottom plate. And the inner wall of the side plate is provided with a sliding block. The inner end of the movable lower pressing plate 102 is provided with a sliding groove matched with the sliding block.

A groove 701 is formed in the outer peripheral wall of the connecting shaft 700. The knuckle spindle seat 200 comprises a hollow spindle seat cavity 201 and a first connecting plate 202 arranged at the lower end of the spindle seat cavity 201. A first threaded hole is formed in the side wall of the shaft seat cavity 201. The connecting shaft 700 extends into the shaft seat cavity 201 and is detachably connected with the knuckle shaft seat 200 through a first connecting piece 800 which is installed in a first threaded hole in a penetrating mode.
The knuckle base 400 comprises a hollow base cavity 401 and a second connecting plate 402 which is arranged at the upper end of the base cavity 401 and is detachably connected with the first connecting plate 202. The steering knuckle shaft seat and the steering knuckle base are matched with each other, the relative position of the steering knuckle shaft seat and the steering knuckle base can be adjusted, and then the included angle between the clamping plate and the insulating rod can be adjusted.
An adjusting component 300 which sequentially penetrates through the shaft seat cavity 201, the base cavity 401 and the cavity is arranged between the movable lower pressing plate 102 and the rotating handle 600. The adjusting assembly 300 comprises a screw 301 which is arranged in the connecting shaft 700 in a penetrating manner and is in threaded fit with the connecting shaft 700, a universal transmission shaft 302 connected with the lower end of the screw 301, a universal transmission shaft seat 304 connected with the lower end of the universal transmission shaft 302 and a transmission rod 305 connected with the universal transmission shaft seat 304; the upper end of the screw 301 is connected with the movable lower pressing plate 102. Because the connecting shaft is embedded and installed in the cavity of the shaft seat, the adjusting assembly actually penetrates through a threaded hole II formed in the middle of the connecting shaft, specifically, a screw rod in the adjusting assembly penetrates through the threaded hole II, the upper end of the screw rod is fixedly connected with the bottom of the movable lower pressing plate, and the lower end of the screw rod is fixedly connected with the upper end of the universal transmission shaft. The universal transmission shaft is a flexible shaft, and can be bent when the conductor end and the rod body rotate relatively, so that the relative angle between the conductor end and the rod body can be adjusted conveniently.
Further, a second threaded hole for the screw 301 to pass through and be in threaded fit with the screw 301 is formed in the connecting shaft 700. The screw rod and the connecting shaft form a screw rod, the connecting shaft is equivalent to a screw rod nut, the screw rod is equivalent to a screw rod, and when the screw rod rotates, the screw rod and the connecting shaft move relatively.
Further, the first connecting plate 202 is detachably connected with the second connecting plate 402 through a second connecting piece 900; a first connecting hole 203 is formed in the first connecting plate 202; a second connecting hole 403 is formed in the second connecting plate 402; the first connecting piece 800 is in threaded connection with the first threaded hole; the inner end of the first connecting piece 800 extends into the groove.
Further, the lower end of the knuckle spindle seat 200 and the outer side of the knuckle base 400 are sleeved with insulating sleeves. The insulating sleeve plays a role in water resistance and insulation, and operation safety is ensured.

Furthermore, a first mounting hole is formed in the universal transmission shaft seat 304, a fixing portion 303 is arranged at the lower end of the universal transmission shaft, and the fixing portion 303 is fixed in the first mounting hole.
Furthermore, a second mounting hole 601 is formed in the rotating handle 600, and the lower end of the transmission rod 305 is fixed in the second mounting hole 601.
As shown in fig. 4, the clamp plate of the present invention can rotate 360 degrees in the circumferential direction of the connecting shaft when the connecting shaft is engaged with the knuckle spindle seat. 360 degrees rotations can take place through making splint, can adjust the angle of splint mouth, make things convenient for the wire to get into in the double-layered mouth of splint. For example: when the conductor end and the rod body form an angle of 120 degrees, a worker can conveniently hold the tail end of the rod body to butt the conductor end on a grounding point of a 35kV downlead (the downlead is characterized in that the conductor is almost vertical to the ground, and the conductor is 75-90 degrees to the ground), at the moment, if a clamping opening of the clamping plate faces upwards, the conductor of the grounding point (almost vertical to the ground) is difficult to place into the clamping opening, and if the clamping opening rotates for an angle to enable the clamping opening to face the conductor, the conductor of the grounding point (almost vertical to the ground) is easy to place into the clamping opening.
As shown in fig. 5, the angle between the upper half part (set as a conductor end) formed by the knuckle spindle seat, the connecting shaft and the clamping plate and the lower half part (set as a rod body) formed by the knuckle base, the insulating rod and the rotating handle can be adjusted as required, and the angle adjusting range is 0-180 degrees.
As shown in fig. 6, when the rotating handle is rotated, the adjusting assembly can rotate along with the rotating handle, and because the screw rod is in threaded fit with the connecting shaft, when the screw rod rotates, the relative position of the screw rod and the connecting shaft can change, and the screw rod and the connecting shaft move up and down along the axial direction of the connecting shaft, so that the distance between the movable lower pressing plate and the top plate is changed.
In the prior art, as shown in fig. 7a, in order to ensure firm installation, a worker needs to make a conductor end perpendicular to a lead, and under the condition of ladder climbing operation, the worker is difficult to use the length of an insulating rod, can only ascend further, and needs to stand at the middle upper part of the insulating ladder; . In order to keep balance by lifting the ground wire operating rod, the middle part of the other hand-held insulating rod is needed. The body is also slightly reclined in order to keep a safe distance from the ground point as much as possible. The length of the insulating rod cannot be effectively utilized in the operation mode, the safe distance between a human body and the grounding point cannot be guaranteed, and the body posture on the insulating ladder is not safe. As shown in fig. 7b, when the universal clamping plate type ground wire operating rod is used for ground wire installation, the conductor end can be adjusted by 360 degrees, the conductor end and the rod body can be adjusted by 180 degrees, and the adjusting assembly enables a top plate and the movable lower pressing plate to form resultant force, so that the lead of the grounding point is clamped, and a worker can adjust the angle of the ground wire operating rod before climbing operation, thereby achieving the purposes of fully utilizing the length of the insulating rod and ensuring the installation of a vertical included angle between the conductor end and the lead of the grounding point, enabling the worker to hold the tail end of the ground wire operating rod with both hands to rotate the rotating handle to install the ground wire when standing on the insulating ladder for grounding operation, fully utilizing the length of the insulating rod, avoiding the need of further ascending and backward pitching, and keeping a safe distance of more than 1 meter with a 35KV grounding point to finish grounding installation, and being safe and labor-.
Specifically, when an operator climbs a ladder to install a ground wire of a 35kV down lead or installs a ground wire with a higher grounding position, the orientation of the clamping plate and the included angle between the rod body and the conductor end are firstly adjusted (the position of the connecting shaft in the steering knuckle shaft seat is adjusted, the orientation of the clamping plate is changed, the relative position of the steering knuckle shaft seat and the steering knuckle base is adjusted, the included angle between the rod body and the conductor end is changed), the rod body and the conductor end are about 120 degrees, so that the tail end of the rod body can be held by hand, the tail end of the rod body stands in the middle (or the middle lower part) of the ladder to connect the conductor end with a wire at 90 degrees, the wire is in the clamping plate opening at the moment, then the rotating handle at the tail part is rotated, the rotating force drives the universal transmission shaft to rotate through the transmission rod, the screw rod is further.
In addition, in a relatively narrow space such as a switch cabinet, a conventional ground wire operating rod cannot be installed in the narrow space due to the length problem of a rod body, and taking a busbar as an example, the busbar is arranged in a relatively narrow space, for example, in the switch cabinet, a conventional clamping plate type ground wire cannot be adjusted due to the length angle of a ground wire rod, so that the ground wire can be installed only on a middle-phase (B-phase) busbar, the ground wire cannot be effectively installed on side-phase (a-phase and C-phase), and only a conductor end of the ground wire rod can be 'lapped' at a grounding position of the side-phase, as shown in fig. 8a specifically. The universal clamping plate type ground wire operating rod has the advantages that the orientation of the clamping plate can be adjusted, the included angle between the conductor end and the rod body can also be adjusted, and the universal clamping plate type ground wire operating rod has obvious installation advantages in the scene as shown in fig. 8 b.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
