Technical Field
[0001] This invention relates to the field of electrical equipment technology, and more specifically, to a grounding device for power equipment. Background Technology
[0002] When high-voltage electrical equipment in a substation is undergoing maintenance during a power outage, grounding wires should be installed or grounding switches should be closed on all sides that may supply power to the equipment. Currently, the most commonly used grounding wires in 500kV and above substations are phase-separated jaw screw-type grounding wires. These grounding wires consist of conductor end clamps, short-circuit wires, grounding end clamps, and grounding operating rods. The jaw size is controlled by an adjustable bolt inside the conductor end clamp, and rotating the bolt clamps the lead wires of the equipment under maintenance.
[0003] The grounding wires of 500kV electrical equipment are generally about 9 meters above the ground. The grounding wires of other AC and DC electrical equipment with higher voltage levels are much higher than 9 meters. They are usually installed and removed using aerial work platforms, which is quite difficult. Moreover, in actual operation, operators need to fix the grounding operating rod while rotating the bolt, which often results in the wire end clamps not being tightly locked or misaligned, easily causing unreliable connections.

[0010] Furthermore, there are two gripper assemblies, which are arranged vertically at intervals. When the gripper assemblies are in the gripping state, the clamping holes of the two gripper assemblies can be non-axial.
[0011] Furthermore, the fifth driving member is disposed on the gripper seat, and the gripper includes a plurality of vertical claws rotatably disposed on the fifth driving member in a vertical direction. The plurality of vertical claws are spaced apart in a circumferential direction along the fifth driving member, and the plurality of vertical claws can move closer to or further away from each other.
[0012] Furthermore, the gripper assembly also includes a rotating lead screw and multiple gears, which are arranged one-to-one on multiple vertical jaws.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] like Figures 1 to 5As shown, this embodiment of the invention provides a grounding operation device for power equipment. The grounding operation device includes a frame 10, a gripper assembly 20, and a clamping jaw assembly 30. The upper end of the frame 10 has a suspension part 11, and the lower end of the frame 10 has an adjustment part. The gripper assembly 20 includes a gripper seat 21, a deformable gripper, a first driving member 22, and a second driving member 23. The first driving member 22 is drivenly connected to the gripper seat 21, so that the gripper seat 21 is vertically movably mounted on the frame 10. The gripper is mounted on the gripper seat 21 and has a gripping state of gripping the operating rod and a releasing state of releasing the operating rod. The drive member 23 can drive the gripper to switch between a clamping state and a releasing state; the gripper assembly 30 is disposed below the gripper assembly 20. The gripper assembly 30 includes a gripper base 31, a deformable gripper, a third drive member, a fourth drive member 32, and a fifth drive member 33. The third drive member is driven to connect with the gripper base 31 so that the gripper base 31 is movably disposed on the frame 10. The fourth drive member 32 drives the gripper to be rotatably disposed on the gripper base 31. The gripper has a clamping state of clamping the operating rod and a releasing state of releasing the operating rod. The fifth drive member 33 can drive the gripper to switch between the clamping state and the releasing state.
[0029] According to the technical solution of the present invention, the substation grounding operation device includes a frame 10, a gripper assembly, and a clamping jaw assembly. The grounding end clamp of the phase jaw spiral compression grounding wire is connected to the grounding stake. The second driving member 23 drives the gripper to switch to the loose state, places the grounding operation rod in the deformable gripper, and drives the gripper to switch to the clamping state to clamp the operation rod. The frame 10 is suspended on the maintenance equipment through the suspension part 11, and the posture of the frame 10 is adjusted by the adjustment part so that the jaw of the conductor end clamp corresponds to the drain wire. The first driving member 22 drives the gripper seat 21 to move vertically downward so that the drain wire is located in the jaw of the conductor end clamp. The third driving component then moves the gripper seat 31 to align with the lower end of the operating rod. The fifth driving component 33 switches the gripper to the clamping state to clamp the operating rod. The second driving component 23 then switches the gripper to the releasing state, and the fourth driving component 32 rotates the gripper, causing the sleeve of the operating rod to rotate relative to the bolt, thereby moving the bolt to close the jaws of the wire end clamp and hold the drain wire. This allows the drain wire to be grounded using a phase-separated jaw spiral-clamped grounding wire. Compared to manual operation, this method is simpler and more reliable.
[0030] The operating rod includes a sleeve and a bolt threadedly connected to the sleeve. The bolt is located at the jaw opening of the wire end clamp. By rotating the sleeve, the bolt can be driven to move relative to the sleeve, thereby opening or closing the jaw opening of the wire end clamp.
[0031] Specifically, when the gripper is in the clamping state, the chuck is in the loose state, and the gripper uses the gripper to clamp the operating rod. When the gripper is in the loose state, the chuck is in the clamping state and can rotate relative to the chuck seat. At this time, the chuck uses the chuck to clamp the operating rod and drive the sleeve of the operating rod to rotate.
[0032] like Figure 2 As shown, the gripper includes multiple arc-shaped claws 24 that are laterally swingable on the gripper base 21. The second drive member 23 is drivenly connected to all the arc-shaped claws 24, and the multiple arc-shaped claws 24 together form a clamping hole for clamping the operating rod. The gripper with the above structure, which uses multiple arc-shaped claws 24 to clamp the operating rod together, has the advantage of simple structure.
[0033] In this embodiment, multiple arc-shaped claws 24 extend laterally, and the axis of the clamping hole formed by the multiple arc-shaped claws 24 extends vertically.
[0034] When the gripper is in a gripping state, the inner side of the arc-shaped gripper 24 is in contact with the side wall of the operating rod.
[0035] like Figure 2 As shown, there are two arc-shaped claws 24, which are respectively set on both sides of the gripper seat 21. The two arc-shaped claws 24 are used to grip the operating rod together, which has the advantages of simple structure and easy operation.
[0036] The gripper assembly 20 also includes a limiting member 25, which is laterally telescopically mounted on the gripper base 21. When the gripper is in the clamping state, the limiting member 25 extends into the clamping hole, and the limiting member 25 and multiple arc-shaped claws 24 together clamp the operating rod. By utilizing the fact that the limiting member 25 can fit against one side of the operating rod, and thus cooperate with the gripper to clamp the operating rod together, the clamping of the operating rod is made more stable.
[0037] In this embodiment, the two arc-shaped claws 24 can fit against one side of the operating rod, and the limiting member 25 can fit against the other side of the operating rod, thereby achieving positioning of both sides of the operating rod and making the clamping of the operating rod more secure.
[0038] Specifically, the two arc-shaped claws 24 are separated and stacked at opposite ends, and when the claws switch from a loose state to a tight state, the two arc-shaped claws 24 gradually cross.
[0039] In other embodiments, the opposite ends of the two arc-shaped claws 24 can be hinged together, and the arcs of the two arc-shaped claws 24 can be oriented in opposite directions, so that the two arc-shaped claws 24 intersect to form a clamping hole.
[0040] like Figure 2As shown, the gripper assembly 20 also includes a swing plate 26, and the second driving member 23 is a push rod disposed on the gripper seat 21. The push rod is drivenly connected to the swing plate 26, so that the swing plate 26 is rotatably disposed on the gripper seat 21. The swing plate 26 is hinged to the arc-shaped claw 24. Using the swing plate 26 to drive the arc-shaped claw 24 to swing relative to the gripper seat 21 has the advantage of simple transmission structure.
[0041] In this embodiment, a connecting seat is provided at the front end of the push rod, and there are two swing plates 26. The two swing plates 26 drive the corresponding arc-shaped claws 24 to swing, and one end of each swing plate 26 is hinged to the connecting seat. During the process of the push rod driving the connecting seat to move, the connecting seat can guide and cooperate with the claw seat 21.
[0042] like Figure 2 As shown, the limiting component 25 is a limiting push rod. The method of using the limiting push rod to limit the operating rod has the advantages of simple structure and low cost.
[0043] The end of the limiting push rod is provided with a limiting protrusion, and the side of the limiting protrusion facing the operating rod is an arc-shaped surface that can cooperate with the operating rod.
[0044] In this embodiment, the gripper assembly 20 further includes a gripper screw 27, a gripper guide rail 28, and a gripper slider 29. The gripper guide rail 28 is vertically mounted on the frame 10. The gripper slider 29 is sleeved on the gripper screw 27 and threadedly engaged with it. The first drive unit 22 is a motor, which is driven by the gripper screw 27 to rotate around its own axis. When the gripper screw 27 rotates, the gripper slider 29 slides along the extension direction of the gripper guide rail 28. The gripper seat 21 is mounted on the gripper slider 29. Using the above-described gripper assembly 20, the first drive unit 22 drives the gripper screw 27 to rotate, thereby causing the gripper slider 29 to move relative to the gripper screw 27. The gripper slider 29 then drives the gripper seat 21 to move, thus enabling the gripper to move vertically and adjust the vertical position of the operating rod.
[0045] like Figure 1 As shown, there are two gripper assemblies 20, which are arranged vertically at intervals. When the gripper assemblies 20 are in the clamping state, the clamping holes of the two grippers are not coaxial. By making the clamping holes of the two grippers not coaxial, the operating rod can be tilted at a certain angle vertically, which facilitates the insertion of the drain wire into the jaw of the wire end clamp.
[0046] Specifically, when clamping the operating rod, one of the gripper assemblies 20 can be used to clamp the operating rod first, or the clamping holes of two gripper assemblies 20 can be set coaxially to make the operating rod vertical. Then, according to the position of the drainage line and the orientation of the wire end clamping the jaw opening, one of the gripper assemblies 20 can be adjusted so that the clamping holes of the two grippers are not coaxial, thereby tilting the operating rod at a certain angle so that there is a certain angle between the jaw opening and the vertical direction. When adjusting the vertical position of the operating rod, it is convenient for the drainage line to enter the jaw opening.
[0047] like Figure 5 As shown, the fifth driving member 33 is disposed on the gripper seat 31. The gripper includes a plurality of vertically rotatable claws 34 disposed on the fifth driving member 33. The plurality of vertical claws 34 are spaced apart circumferentially along the fifth driving member 33 and can move closer to or further away from each other. The gripper with the above structure has the advantages of simple structure and low cost.
[0048] like Figure 5 As shown, the gripper assembly 30 also includes a rotating lead screw 35 and multiple gears 36. The gears 36 are correspondingly arranged on multiple vertical jaws 34. The fifth drive unit 33 is a motor, and the rotating lead screw 35 is mounted on the output shaft of the fifth drive unit 33. The multiple gears 36 mesh with the rotating lead screw 35 respectively. When the rotating lead screw 35 rotates, the multiple vertical jaws 34 can move closer to or further away from each other. The fifth drive unit can drive the rotating lead screw 35 to rotate, which in turn drives the multiple gears 36 to rotate, thus switching the grippers between a clamping state and a loosening state.
[0049] In this embodiment, the pawl 34 is disposed on the rotating shaft of the gear 36, and the rotating shaft extends laterally. When the gear 36 rotates, the pawl 34 can rotate with the rotating shaft.
[0050] like Figure 5 As shown, the fourth driving component 32 is a motor, which is mounted on the gripper base 31. The fifth driving component 33 is mounted on the fourth driving component 32, and the fourth driving component 32 and the fifth driving component 33 are driven together to allow the fifth driving component 33 to rotate vertically. With this structure, the fourth driving component 32 can drive the fifth driving component 33 to rotate, which in turn drives the gripper to rotate, and the gripper drives the operating rod to rotate.
[0051] like Figure 1As shown, the gripper assembly 30 also includes a first guide rail slider 37, a second guide rail slider 38, and a third guide rail slider 39. The third driving component includes a first motor 391, a second motor 392, and a third motor 393. The first motor 391 drives the first guide rail slider 37 to be movably mounted vertically on the frame 10, and the first guide rail slider 37 extends along a first direction. The second motor 392 drives the second guide rail slider 38 to be movably mounted on the first guide rail slider 37 along the first direction, and the second guide rail slider 38 extends along a second direction perpendicular to the first direction. The third motor 393 drives the third guide rail slider 39 to be movably mounted on the second guide rail slider 38 along the second direction. The gripper seat 31 is mounted on the third guide rail slider 39. With the above structure, the first guide rail slider 37, the second guide rail slider 38, and the third guide rail slider 39 can be used to move the gripper seat 31 in three directions to adjust the position of the gripper seat 31.
[0052] like Figure 1 As shown, the suspension part 11 includes a wheel and a suspension rope. The wheel is rotatably mounted on the frame 10 in the lateral direction. The suspension rope is wound around the wheel and connected to the wheel. By rotating the wheel, the suspension rope can be wound onto the wheel, thereby lifting the frame 10 onto the maintenance equipment.
[0053] The process begins by suspending the suspension rope on the maintenance equipment. By rotating the reel, the suspension rope can be wound up onto the reel.
[0054] Specifically, the adjustment unit includes an adjustment rope, and a lifting ring 12 is provided at the lower end of the frame 10. The adjustment rope is connected to the lifting ring 12. By pulling the adjustment rope, the posture of the frame 10 can be adjusted, thereby adjusting the posture of the operating rod.
[0055] In this embodiment, the method for suspending a phase-separated jaw-type spiral-clamped grounding wire includes the following steps:
[0056] 1) Use a remote-controlled micro drone to suspend the suspension rope of frame 10 on the grounding line of the equipment to be repaired;
[0057] 2) Connect the grounding end clamp of the phase jaw screw-type grounding wire to the grounding stake;
[0058] 3) Place the grounding operating rod in the gripper and hold it tightly, with the position of the grounding operating rod parallel to the extension direction of the frame;
[0059] 4) Adjust the orientation of the wire end clamp jaws according to the relative position of the suspension point of the suspension rope and the grounding point of the equipment under maintenance;
[0060] 5) Adjust the relative position of the two clamps so that the grounding operating rod is tilted at a certain angle, making it easier to insert the drain wire into the jaw of the wire end clamp;
[0061] 6) Rotate the wheel and reel in the suspension rope to raise the frame 10 to about 2 meters below the grounding point of the equipment under maintenance;
[0062] 7) Manually pull the adjustment rope to adjust the position of the frame 10 so that the grounding operating rod is in the optimal suspension position;
[0063] 8) The first driving component 22 drives the gripper to move vertically, causing the phase jaw screw-type grounding wire to rise until the wire end clamp and the grounding point of the equipment under maintenance are at the same height;
[0064] 9) The first driving component 22 drives the gripper to move vertically, causing the wire end clamp to descend, so that the jaws of the wire end clamp hook onto the drain wire.
[0065] 10) Adjust the relative position of the two grippers so that the grounding operating rod is parallel to the frame 10. Adjust the position of the grippers and use the fifth drive unit 33 to drive the grippers to clamp the operating rod. Adjust both grippers to be in the loose state so that the grounding operating rod can be rotated.
[0066] 11) The fourth driving component 32 is used to drive the grounding operating rod to rotate, thereby tightening the wire end clamp;
[0067] 12) Check that the conductor end clamp is securely clamped to the grounding point of the equipment under maintenance;
[0068] 13) Release the two gripping claws and the clamping claws in sequence;
[0069] 14) Rotate the wheel to smoothly lower the frame 10 to the predetermined position;
[0070] 15) The lifting ropes were removed manually.
