Description

Technical Field

[0001] The invention relates to the field of grounding wire operation equipment, in particular to an intelligent electric grounding wire clamping device. Background Art

[0002] When inspecting and maintaining power system lines, in order to avoid accidental voltage on power-off equipment and lines, maintenance personnel usually need to use a grounding wire clamp to ground the wire, thereby introducing current into the earth and ensuring that the maintenance personnel are in a safe working environment.

[0003] A Chinese patent with relevant announcement number CN114792894B discloses a grounding wire clamping device, including a first transmission component, a second transmission component and a clamping mechanism connected to the second transmission component. The first transmission component can move relative to the second transmission component, so that the first transmission component has a first state and a second state. When the first transmission component is in the first state, the first transmission component is engaged with the second transmission component, and the first transmission component is used to drive the second transmission component to rotate so that the clamping mechanism switches between a clamped state and a loosened state; when the first transmission component is in the second state, the first transmission component is separated from the second transmission component.

[0004] In the existing power system lines, the busbars used for power transmission include rectangular busbars, trough busbars, tubular busbars, aluminum stranded wires, copper stranded wires, steel core aluminum stranded wires, expanded diameter hollow conductors, etc. Among them, there are many common diameter specifications for tubular busbars, such as 30mm, 50mm, 80mm, etc.

[0005] With respect to the above-mentioned related technologies, in order to solve the problem that the vertical busbar is not conducive to clamping, the existing grounding wire clamping device has an embracing mechanism rotatably connected on the surface, which is used to cooperate with the existing clamp structure to clamp the busbar. Since the opening diameter of the existing grounding wire clamp is limited, it is generally suitable for busbars with smaller diameters such as aluminum stranded wires, and it is not easy to clamp thicker tubular busbars. At the same time, the embracing mechanism newly added to the clamp in the prior art has a small force contact area with the rectangular busbar when applied to a rectangular busbar, and the power arm of the embracing mechanism is smaller than the resistance arm, and it is not easy to apply a large clamping torque, making it difficult to achieve stable clamping of the rectangular busbar. In summary, the existing grounding wire clamping device is not easy to be stably applied to busbars of various models. Summary of the invention

[0006] Based on this, the purpose of the present invention is to provide an intelligent electric grounding wire clamping device to solve the technical problem that the existing grounding wire clamping device is not easy to stably apply to busbars of various models.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent electric grounding wire clamping device, comprising a clamping frame, the clamping frame having a clamping plane and a clamping arc surface for clamping a busbar, and also comprising a clamping plate, the clamping plate is rotatably connected to one end of the clamping plane of the clamping frame, the end of the clamping plate away from its own rotating shaft is fixedly connected with an arc-shaped first toothed belt, a driving gear for meshing with the first toothed belt is arranged in the clamping frame, and the clamping arc surface and the first toothed belt are both arc-shaped structures with the center of the circle located on the rotating shaft of the clamping plate.

[0008] By adopting the above technical solution, the driving gear in the clamping frame is used in conjunction with the arc-shaped rack connected to the clamping plate, so that the clamping plate can rotate to stably clamp busbars such as rectangular busbars or tubular busbars, thereby effectively improving the adaptability of the grounding wire clamping device to various types of busbars.

[0010] Preferably, the push plate is extended during the closing process of the clamping plate to deform the end of the conductive plate, thereby increasing the contact area between the conductive plate and the busbar.

[0011] The present invention is further configured such that the clamping plane of the clamping frame is provided with telescopic strips arranged along the length direction, and a spring is provided between the end of the telescopic strip and the clamping frame.

[0012] Preferably, the telescopic strip can increase the contact area between the clamping frame and the tubular busbar when clamping the tubular busbar, thereby improving the clamping stability of the tubular busbar.

[0013] The present invention is further configured such that the clamping frame is rotatably connected to a telescopic rod on the back side of the clamping plane, and an adjusting knob is provided at the rotating shaft of the telescopic rod and the clamping frame.

[0014] Preferably, the orientation of the clamping frame is adjusted by rotating the adjusting knob, so that the clamping frame can adapt to busbars with various inclination angles.

[0015] The present invention is further configured such that the push plate is provided with a second toothed belt in the horizontal direction, and the rotating shaft of the driving wheel is extended into the clamping plate and connected with a transmission gear set for cooperating with the second toothed belt.

[0016] Preferably, the push plate is driven to extend by the torque generated by the friction between the driving wheel and the clamping arc surface, thereby deforming the conductive plate to increase the contact area with the busbar.

[0017] The present invention is further configured such that the first toothed belt and the driving wheel are disposed on both the bottom surface and the top surface of the end portion of the clamping plate.

[0018] Preferably, the clamping plate is capable of applying force uniformly to the clamped surface of the busbar.

[0019] The present invention is further configured such that a toothed belt sliding groove for sliding the first toothed belt is provided in the clamping frame.

[0020] Preferably, the toothed belt slide groove can guide the first toothed belt.

[0021] The present invention is further configured such that when the clamping plate, the clamping plane and the clamping arc surface jointly clamp the busbar, the clamping plate is in a closed state, and a locking structure for keeping the clamping plate in an expanded state is provided at the rotating shaft of the clamping plate and the clamping frame.

[0022] Preferably, when the locking structure clamps the high-place busbar, the clamping plate is kept in an expanded state until the busbar is located in the clamping frame and then the locking structure is released to clamp the busbar.

[0024] Preferably, when the clamping plate needs to be closed, the clamping plate is rotated slightly in the expansion direction so that the end of the locking plate leaves the slot. The locking structure can be released after the locking plate is reset, and the clamping plate is closed by the torsion spring force at its own rotating shaft.

[0025] In summary, the present invention mainly has the following beneficial effects:

[0026] 1. The present invention rotatably connects a clamping plate by means of a clamping frame having both an arc-shaped clamping surface and a parallel clamping surface, and utilizes a driving gear in the clamping frame to cooperate with an arc-shaped rack connected to the clamping plate, so that the clamping plate can stably clamp a busbar such as a rectangular busbar or a tubular busbar after rotation, thereby effectively improving the adaptability of the grounding wire clamping device to various types of busbars.

[0027] 2. The present invention drives the pinion to rotate through a motor, and the pinion meshes with the arc-shaped rack to drive the clamping plate to rotate, so as to avoid the power arm of the clamping plate being smaller than the resistance arm. After the clamping plate contacts the busbar, the busbar is close to the clamping arc surface by the reaction force of the clamping plate and the clamping plane, and is finally stably clamped between the clamping plane, the clamping arc surface and the clamping plate, thereby increasing the friction between the grounding wire clamping device and the busbar, thereby avoiding the grounding wire clamping device from loosening;

[0028] 3. The present invention arranges telescopic blocks that can be extended and retracted at intervals along the length direction on the parallel clamping surfaces, and connects springs between the telescopic blocks and the clamping frame. When clamping the busbar with an arc surface, the telescopic blocks that contact the busbar are compressed and contracted, which effectively increases the contact area between the clamping device and the busbar, and further improves the clamping stability of the clamping device.

[0029] 4. The present invention arranges a conductive plate on the side of the clamping plate facing the busbar, and uses a push plate rotatably connected to the end of the conductive plate to push the end of the conductive plate during the rotation of the clamping plate, so that the conductive plate bends toward the busbar, further expanding the area of ​​the clamping device in contact with the busbar and conducting electricity, thereby improving the stability of the current during the flow process;

[0030] 5. The present invention rotates and connects a driving wheel in contact with the clamping arc surface at one end of the clamping plate away from its own rotating shaft, so that the push plate is automatically extended to push the conductive plate in the process of the clamping plate rotating to clamp the busbar, and the push plate is retracted in the process of the clamping plate releasing the busbar, thereby conveniently resetting the conductive plate, so that the conductive plate is automatically pushed to deform and fit the busbar in the process of the clamping plate clamping the busbar;

[0031] 6. The present invention conveniently adapts to busbars with different inclination angles by rotating the telescopic rod on the side of the clamping frame and adjusting the angle of the clamping frame relative to the top of the telescopic rod by using the adjusting knob. The extension of the telescopic rod is also beneficial for maintenance personnel to clamp the grounding wire of the busbar at a high place.

[0032] 7. The present invention arranges a torsion spring at the rotating shaft of the clamping frame that is rotatably connected to the clamping plate, so that the torsion spring is compressed when the clamping plate is unfolded. After the clamping plate is unfolded, the locking structure between the clamping plate and the clamping frame limits the resetting of the clamping plate. When the clamping frame approaches the busbar, it contacts the locking structure to rotate and reset the clamping plate, thereby further reducing the difficulty of maintenance personnel in clamping the busbar grounding wire at a high place.

[0044] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] The following describes an embodiment of the present invention based on its overall structure.

[0046] First embodiment:

[0047] Please refer to 1-9. The clamping frame 1 has a clamping plane 101 and a clamping arc surface 102 for clamping the busbar. The clamping plate 2 is rotatably connected to one end of the clamping plane 101 of the clamping frame 1. The end of the clamping plate 2 away from its own rotation axis is fixedly connected with an arc-shaped first toothed belt 3. A driving gear 104 for meshing with the first toothed belt 3 is arranged in the clamping frame 1. Specifically, a driving motor is installed in the clamping frame 1. The driving motor rotates the driving gear 104 through a transmission structure. The clamping arc surface 102 and the first toothed belt 3 are both arc-shaped structures with the center of the circle located on the rotation axis of the clamping plate 2, so that the driving gear 104 can always keep meshing with the first toothed belt 3 during the rotation of the clamping plate 2.

[0048] See also Figure 1-4 The clamping plate 2 is fixedly connected with two conductive strips 201 facing the clamping plane 101. The conductive strips can contact the busbar and thus conduct electricity. The clamping plate 2 is fixedly installed with a terminal 10 on the other side where the conductive strips 201 are provided. The terminal 10 is used to connect the grounding lead 11. The conductive strips 201 pass through the clamping plate 2 and are electrically connected to the grounding lead 11.

[0049] In this embodiment, the driving motor used is specifically a miniature planetary reduction motor. The output shaft of the driving motor is transmitted to the rotating shaft of the driving gear 104 through a worm gear. The planetary reduction motor and the worm gear structure can ensure that the driving gear 104 can output sufficient torque, so that the clamping plate 2 can achieve stable clamping of the busbar.

[0050] In order to prevent the first toothed belt 3 from slipping when the planetary reduction motor is not working, the clamping frame 1 is provided with an electric brake at the rotating shaft of the driving gear 104. When the driving motor is not working, the electric brake is in a state of locking the rotating shaft of the driving gear 104 to prevent the driving gear 104 from rotating uncontrolled.

[0051] Furthermore, in order to facilitate the control of the forward and reverse rotation of the drive motor, radio remote control, infrared remote control, voice control and the like may be used, which are not limited in the present embodiment.

[0052] In the above embodiment, please refer to Figure 1-4 A toothed belt slide groove 103 for sliding the first toothed belt 3 is provided in the clamping frame 1. The toothed belt slide groove 103 is also an arc-shaped structure with the center located at the rotating shaft of the clamping plate 2. The toothed belt slide groove 103 can guide the first toothed belt 3 and improve the stability of the first toothed belt 3 during sliding.

[0053] In the above embodiments, please refer to Figure 5-8When the clamping plate 2, the clamping plane 101 and the clamping arc surface 102 jointly clamp the tubular busbar, the clamping plate 2 is in a closed state, and a locking structure for keeping the clamping plate 2 in an expanded state is provided at the rotating shaft of the clamping plate 2 and the clamping frame 1. Specifically, the locking structure can be any structure that can lock the clamping plate 2 and maintain the rotation angle of the clamping plate 2, such as an electric-controlled brake and an electric-controlled telescopic block. When the locking structure clamps the high busbar, the clamping plate 2 remains in an expanded state until the busbar is located in the clamping frame 1, and the locking structure is released to clamp the busbar.

[0054] Furthermore, in order to better control the opening and closing of the clamping plate 2, in other possible embodiments, a motor or a rotary cylinder control component for driving the clamping plate 2 to rotate can be directly set at the rotating shaft of the clamping plate 2 and the clamping frame 1.

[0055] Second embodiment:

[0056] See also Figure 1-4 On the basis of the first embodiment, the difference from the first embodiment is that the end of the clamping plate 2 away from its own rotation axis is rotatably connected to a driving wheel 4 for contacting the clamping arc surface 102. Specifically, the driving wheel 4 is a rubber wheel, which will undergo radial elastic deformation after contacting the clamping arc surface 102 to ensure that the driving wheel 4 does not slip on the clamping arc surface 102. The surface of the clamping plate 2 for contacting the busbar is fixedly connected to a conductive plate 6. Specifically, the conductive plate 6 can undergo elastic deformation. One end of the conductive plate 6 close to the rotation axis of the clamping plate 2 is fixedly connected to the clamping plate 2, and the other end is rotatably connected to a push plate 5 for pushing the conductive plate 6 toward the busbar. The push plate 5 is slidably connected to the end of the clamping plate 2. The side of the conductive plate 6 facing the clamping plane 101 in this embodiment is flush with the conductive belt 201, and the end of the conductive plate 6 is also electrically connected to the ground lead 11.

[0057] During the movement of the clamping plate 2 toward the clamping plane 101 in this embodiment, the driving wheel 4 contacts the clamping arc surface 102, and the push plate 5 is slid out through the transmission structure in the clamping plate 2. During the closing process of the clamping plate 2, the push plate 5 is extended. The extension of the push plate 5 causes the end of the conductive plate 6 to deform, thereby increasing the contact area between the conductive plate 6 and the busbar.

[0058] In the above embodiments, please refer to Figure 1-4The push plate 5 is provided with a second toothed belt 501 in the horizontal direction. After the rotating shaft of the driving wheel 4 extends into the clamping plate 2, a transmission gear set for cooperating with the second toothed belt 501 is connected. Specifically, the rotating shaft of the driving wheel 4 is coaxially fixedly connected with a gear in the clamping plate 2. The gear meshes with a reversing gear, and the reversing gear meshes with the teeth on the second toothed belt 501. In the process of the clamping plate 2 rotating and closing, the driving wheel 4 is observed from a top-down perspective. The driving wheel 4 rotates counterclockwise, and the gear coaxially connected to the driving wheel 4 causes the reversing gear to rotate clockwise. After the clockwise rotating reversing gear meshes with the second toothed belt 501, the second toothed belt 501 is extended toward the clamping plane 101, pushing the end of the conductive plate 6 to deform it, and the torque caused by the friction between the driving wheel 4 and the clamping arc surface 102 drives the push plate 5 to extend, thereby causing the conductive plate 6 to deform and increase the contact area with the busbar.

[0059] Furthermore, the push plate 5 can undergo elastic deformation in the horizontal direction, and in the process of extending to push the end of the conductive plate 6, the end of the conductive plate 6 can be brought closer to the busbar, thereby obtaining a larger contact area with the busbar.

[0060] In the above embodiments, please refer to Figure 1-4 The first toothed belt 3 and the driving wheel 4 are arranged on the bottom and top surfaces of the end of the clamping plate 2, so that the clamping plate 2 can apply force evenly to the clamped surface of the busbar, maintaining the balance of pressure applied to the busbar by the top and bottom ends of the clamping plate 2. Furthermore, multiple groups of reinforcing rod structures are cross-arranged between the two first toothed belts 3 to further prevent the first toothed belt 3 from bending when sliding in the toothed belt groove 103.

[0061] The third embodiment:

[0062] See also Figure 5-6 On the basis of the first embodiment, the difference from the first embodiment is that the clamping plane 101 of the clamping frame 1 is arranged with telescopic strips 8 along the length direction, and a spring is arranged between the end of the telescopic strip 8 and the clamping frame 1. The telescopic strip 8 can increase the contact area between the clamping frame 1 and the tubular busbar when clamping the tubular busbar, thereby improving the clamping stability of the tubular busbar. Specifically, after the busbar with an arc-shaped outer surface contacts the telescopic strip 8, the telescopic strip 8 will be compressed and retracted into the clamping frame 1, so that multiple groups of telescopic strips 8 can contact the arc-shaped outer surface of the busbar, which can effectively improve the clamping stability of the busbar compared to a simple clamping plane 101.

[0063] Fourth embodiment:

[0064] See also Figure 3-6On the basis of the first embodiment, the difference from the first embodiment is that the clamping frame 1 is rotatably connected with a telescopic rod 12 on the back side of the clamping plane 101. When the telescopic rod 12 is extended, it is convenient for maintenance personnel to clamp the grounding wire of the high busbar. The telescopic rod 12 is provided with an adjusting knob 9 at the rotating shaft with the clamping frame 1. The adjusting knob 9 is rotated to adjust the direction of the clamping frame 1, so that the clamping frame 1 can adapt to busbars with various inclination angles. Specifically, when it is necessary to clamp the grounding wire of the horizontal busbar, first loosen the adjusting knob 9, rotate the clamping frame 1 so that the opening of the clamping frame 1 faces downward, and then tighten the adjusting knob 9. When it is necessary to clamp the grounding wire of the vertical busbar, first loosen the adjusting knob 9, rotate the clamping frame 1 so that the opening of the clamping frame 1 is horizontal, and then tighten the adjusting knob 9. Specifically, after the adjusting knob 9 is tightened, the friction force at the rotating shaft of the telescopic rod 12 is used to limit the relative rotation of the clamping frame 1 and the telescopic rod 12.

[0065] The fifth embodiment:

[0066] See also Figure 5-9 On the basis of the first embodiment, the difference from the first embodiment is that a torsion spring is provided at the rotating shaft of the clamping plate 2 and the clamping frame 1 for rotating the clamping plate 2 toward the clamping plane 101. Specifically, in the process of the clamping plate 2 rotating away from the clamping plane 101, the torsion spring is in a state of accumulating elastic potential energy, and the clamping frame 1 is provided with a slot 105 at a position of the clamping plane 101 close to the clamping plate 2, and the clamping plate 2 is provided with a receiving groove 202 at a position close to its own rotating shaft, and a locking piece 7 that can be inserted into the slot 105 is rotatably connected in the receiving groove 202, and a torsion spring for retracting the locking piece 7 into the receiving groove 202 is provided at the rotating shaft of the locking piece 7.

[0067] When the locking piece 7 in the present embodiment is inserted into the slot 105, the clamping plate 2 is in an expanded state. When the clamping plate 2 needs to be closed, the clamping plate 2 is slightly rotated in the expansion direction to make the end of the locking piece 7 leave the slot 105. After the locking piece 7 is reset, the locking structure can be released. The clamping plate 2 is closed by the torsion spring force at its own rotating shaft. During specific use, the maintenance personnel first rotate and expand the clamping plate 2 on the ground, then pick out the locking piece 7 from the accommodating groove 202, and insert the end of the locking piece 7 into the slot 105 to complete the expansion of the clamping plate 2. When clamping the grounding wire of the high busbar, the clamping plate 2 can first contact the busbar, and then the clamping plate 2 continues to rotate slightly in the direction away from the clamping plane 101, and the locking piece 7 can leave the slot 105.

[0068] When the intelligent electric grounding wire clamping device is working: after unfolding the clamping plate 2, the clamping frame 1 is moved close to the busbar, so that the busbar is located between the clamping plane 101 and the clamping arc surface 102 of the clamping frame 1, and then the clamping plate 2 is rotated and closed, so that the first toothed belt 3 connected to the clamping plate 2 cooperates with the driving gear 104 in the clamping frame 1, and the driving motor in the clamping frame 1 works to rotate the driving gear 104, so that the first toothed belt 3 slides in the toothed belt slide groove 103, and then pushes the clamping plate 2 away from one end of its own rotating shaft, so that the clamping plate 2 rotates close to the busbar, and the clamping plate 2 pushes the busbar to fit the clamping plane 101 and the clamping arc surface 102 to clamp the busbar, which can adapt to tubular busbars and stranded wires of various diameters, and can also achieve stable clamping of rectangular busbars. When it is necessary to release the clamping of the busbar, the driving motor is made to work in reverse to make the first toothed belt 3 exit the toothed belt slide groove 103.

[0069] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
