Description

Technical Field

[0001] This utility model relates to the field of power construction technology, and in particular to an auxiliary installation support for a voltage testing grounding ring. Background Technology

[0002] With the rapid improvement in the insulation level of power distribution lines, voltage testing and grounding typically employs dedicated voltage testing and grounding rings installed on insulated wires for voltage detection and grounding. These voltage testing and grounding rings utilize built-in piercing teeth that, under the action of a clamping screw, penetrate the insulation layer of the insulated conductor to form contact and create a connection, thus enabling voltage testing and grounding.

[0003] However, many insulated overhead lines do not adequately consider potential work points during later maintenance, resulting in an insufficient number of grounding rings. This leads to a shortage of grounding rings when power outages are required for maintenance, compromising the safety of workers from electric shock. Therefore, when an insufficient number of grounding rings is discovered during line inspections, live-line working vehicles are temporarily contacted to replenish the rings before power outages. However, in many rural and mountainous areas where live-line working vehicles cannot reach, grounding rings cannot be installed while the power is on, necessitating manual installation after power is cut off. This poses a significant safety risk to maintenance personnel and constitutes a serious violation of safety regulations. Summary of the Invention

[0004] In order to enable live installation of voltage testing grounding rings in areas such as fields and mountains, this application provides an auxiliary installation support for voltage testing grounding rings.

[0005] This application provides an auxiliary mounting bracket for a voltage detection grounding ring, employing the following technical solution:

[0006] An auxiliary mounting bracket for a voltage testing grounding ring includes a main body. The bottom of the main body has a threaded cylinder for connecting an insulating operating rod. The main body has a groove for inserting the voltage testing grounding ring. Clamps are provided on both sides of the main body, each clamp consisting of two plates hinged together. The rotation axis is set along the length of the main body, and one of the plates is fixedly connected to the main body. A torsion spring is provided at the hinge point of the two plates. When the torsion spring is in its natural state, the two plates are closed. A limiting element is also provided between the two plates to restrict their closure.

[0007] Optionally, the limiting member includes a support rod, one end of which is rotatably connected to one of the clamping plates, and the other end abutting against another clamping plate.

[0008] Optionally, the main body is slidably connected with two limiting rods along its width direction, and the two limiting rods abut against both sides of the voltage testing grounding ring for fixation; the main body is also provided with a driving component for driving the two limiting rods to move closer to each other.

[0009] Optionally, the driving component is a tension spring, with both ends of the tension spring fixedly connected to the bottom of the two limiting rods.

[0010] Optionally, the main body has a groove along its width for the limiting rod to slide; the limiting rod is provided with a hook that extends out of the groove for the tension spring to connect to.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] As can be seen from the above, the auxiliary installation support for the voltage testing grounding ring provided in this application enables remote operation through the connection of the threaded cylinder and the insulating operating rod. The groove and the clamp cooperate to quickly position and fix the voltage testing grounding ring. Combined with the limiting component, it prevents the clamp from closing accidentally. It solves the problems of low installation efficiency and high safety risk in complex terrain in the prior art. It has the advantages of reasonable structure, safe operation and convenient installation under complex terrain conditions. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] Therefore, this application proposes an installation support including a main body 1. The bottom of the main body 1 is provided with a threaded cylinder 11 for connecting an insulating operating rod. The main body 1 has a groove for accommodating a grounding ring 2. The two sides are provided with clamps 3 consisting of two hinged clamps 31. The hinge axis of the clamps 31 is arranged along the length of the main body 1. One clamp 31 is fixed to the main body 1. A torsion spring 33 is provided at the hinge of the two clamps 31 to allow them to close naturally, and a limiting member is provided to restrict the closed state.

[0020] The threaded cylinder 11 refers to the cylindrical structure connected to the insulating operating rod. It can be designed with internal threads to accommodate standard rods, enabling quick assembly and disassembly of the operating rod and support. The groove refers to the slot-shaped structure on the main body 1 for inserting the grounding ring 2. It can be U-shaped or rectangular in cross-section, and its dimensions can be adjusted according to the shape of the grounding ring to ensure initial positioning of the ring. The clamp 3 is a clamping mechanism composed of two clamping plates 31. The hinge axis of the clamping plates 31 is parallel to the length direction of the main body 1. It can be made of metal sheet and achieves opening and closing through the hinge point. The torsion spring 33 applies a closing force to automatically clamp the grounding ring. The limiting component is a constraint structure that prevents the clamping plates 31 from excessively closing. It can include a support rod 32 or a latching device to prevent the clamping plates 31 from accidentally opening due to external force during clamping.

[0021] Specifically, during operation, the insulating operating rod is connected to the support via the threaded cylinder 11, and the grounding ring 2 is inserted into the groove for initial positioning. At this time, the clamp 3 is in an open state under the action of the limiting rod 4. Then, the support and the grounding ring 2 are fed onto the wire together through the insulating operating rod. When the wire passes through the opening of the clamp 3, it will push the limiting rod 4 to disengage from the clamp 31. The clamp 3 will automatically close and clamp the wire under the action of the torsion spring 33 to prevent it from loosening. At this time, the grounding ring can be installed on the wire by using the insulating operating rod in conjunction with the hexagonal sleeve. It should be noted that the fastening process of the grounding ring itself is a mature existing technology. The core of this application is how to feed the grounding ring onto the wire.

[0022] This structure allows operators to perform clamping actions on the ground using an insulated rod, without direct contact with the conductor or climbing the tower. The hinged design of clamp 3 ensures even distribution of clamping force, keeping the grounding ring fixed during installation.

[0023] Compared to existing technologies, traditional methods rely on live-line working vehicles or high-altitude climbing. This solution, through the cooperation of the support and the insulated operating rod, allows operators to complete the installation on the ground, significantly reducing safety risks. Existing technologies require multiple people to work together for temporary repairs, which is time-consuming. This solution simplifies the operation process through the automatic closing of the clamp 3 and the constraint of the limiting component, allowing a single person to complete the installation in a short time. Furthermore, the combination structure of the groove and the clamp 3 solves the problem of traditional tools being unable to effectively fix the grounding ring, avoiding poor contact caused by ring misalignment during installation.

[0024] Through the above technical solution, this application effectively solves the problem of the inability to safely reinstall the grounding ring 2 in complex terrain, reduces the risk of high-altitude operations, and improves installation efficiency. The support structure, through the synergistic action of the clamping mechanism and the limiting component, ensures the stability of the grounding ring during the piercing and tightening process, preventing it from falling off due to vibration or operational errors, and providing a reliable safety guarantee for power outage maintenance operations.

[0025] This application further proposes an auxiliary installation support for a voltage testing grounding ring 2, including a main body 1. The bottom of the main body 1 is provided with a threaded cylinder 11 for connecting an insulating operating rod. The main body 1 has a groove for inserting the voltage testing grounding ring 2. The two sides of the main body 1 are also provided with clips 3, each clip 3 including two clamps 31. The two clamps 31 are hinged to each other, and the rotation axis is set along the length of the main body 1. One of the clamps 31 is fixedly connected to the main body 1. A torsion spring 33 is provided at the hinge of the two clamps 31. When the torsion spring 33 is in its natural state, the two clamps 31 are closed. A limiting member for limiting the closure of the two clamps 31 is also provided between the two clamps 31. The limiting member includes a support rod 32. One end of the support rod 32 is rotatably connected to one of the clamps 31, and the other end abuts against the other clamp 31.

[0026] The support rod 32 is a rod-shaped component connecting the two clamping plates 31. It can be made of metal or high-strength plastic. One end is connected to the clamping plate 31 via a hinge or pin, and the other end abuts against the other clamping plate 31 via a flat or curved surface. The function of the support rod 32 is to provide rigid support when the clamping plates 31 are open, preventing them from automatically closing due to the torsion spring 33, thus keeping the clamping plates 31 in the open state. The rotatable connection refers to a connection method where the support rod 32 and the clamping plate 31 can rotate around a fixed axis. This can be achieved through a hinged structure or a rotating shaft structure, allowing the support rod 32 to adjust its angle as the clamping plates 31 open and close. This structure allows the support rod 32 to retract naturally when the clamping plates 31 are closed and unfold to form support when the clamping plates 31 are open. The abutment refers to the contact state between the end of the support rod 32 and the other clamping plate 31, which can be achieved through a flat surface, a curved surface, or a contact surface with anti-slip texture. This design ensures that the support rod 32 provides stable support when the clamping plate 31 is open, preventing the clamping plate 31 from closing accidentally.

[0027] Specifically, when the clamp 3 needs to be opened, the clamp 31 rotates outward against the spring force of the torsion spring 33. At this time, the support rod 32 rotates with the clamp 31 and gradually unfolds. When the clamp 31 rotates to the target angle, the end of the support rod 32 abuts against another clamp 31, forming a rigid support and preventing the clamp 31 from automatically resetting under the action of the torsion spring 33. Thus, the operator can operate the clamp 31 with one hand, and the support rod 32 automatically maintains the open state of the clamp 31 without additional force, making it easy to place the grounding ring 2 into the groove. After installation, the support rod 32 is manually pushed out of the abutment position, and the clamp 31 automatically closes under the action of the torsion spring 33 to fix the grounding ring 2.

[0028] Compared with existing technologies, traditional clamps 3 typically rely on elastic components or manual fixing to maintain the open state, which can easily lead to accidental closure of the clamp 31 due to elastic fatigue or operational errors. In contrast, this solution uses a rigid support rod 32 to lock the clamp 31 in the open state, which is simple in structure and highly reliable. It avoids the performance degradation problem of elastic components after long-term use and reduces the complexity of manual operation.

[0029] Through the above technical solution, this application can stably keep the clamp 3 open when installing the voltage testing grounding ring 2, avoiding operation interruption or equipment falling off due to accidental closing of the clamp 31 during the operation. It is especially suitable for narrow or complex environments that cannot be reached by live-line working vehicles, and significantly improves the safety and efficiency of manual installation.

[0030] This application further proposes that two limiting rods 4 are slidably connected on the main body 1 along its own width direction, and the two limiting rods 4 abut against both sides of the voltage testing grounding ring 2 for fixation; the main body 1 is also provided with a driving component for driving the two limiting rods 4 to move closer to each other.

[0031] The main body 1 has two sliding limit rods 4 connected along its width, meaning the limit rods 4 can translate along the width of the main body 1. This can be achieved using a sliding rail and slider structure, where the sliding rail can be fixed inside or on the surface of the main body 1. This structure allows the limit rods 4 to adjust their clamping position according to the size of the grounding ring 2, adapting to different installation requirements. The driving component is the mechanism that provides force to move the limit rods 4, which can be implemented using elastic elements or mechanical transmission devices. The driving component continuously applies force to keep the limit rods 4 clamped, ensuring that the grounding ring 2 does not shift during installation.

[0032] Specifically, after the grounding ring 2 is inserted into the groove of the main body 1, the two limiting rods 4 slide along the width direction of the main body 1 and abut against both sides of the grounding ring 2 under the action of the driving component. The driving force of the driving component is transmitted to the limiting rods 4, causing them to automatically adjust to the position of contact with the grounding ring 2, and to achieve fixation by continuously applying pressure. In this process, there is no need to manually adjust the position of the limiting rods 4, and the clamping action can be completed quickly.

[0033] Compared to existing technologies, traditional grounding ring 2 fixing devices typically rely on bolt tightening or fixed-size slots, making it impossible to dynamically adjust the clamping range according to actual installation requirements. This solution achieves adaptive clamping function through the cooperation of the sliding limit rod 4 and the driving component, reducing reliance on manual operation and avoiding installation loosening problems caused by insufficient clamping force.

[0034] Through the above technical solution, this application can automatically adjust the position of the limit rod 4 and apply a stable clamping force during the installation of the voltage testing grounding ring 2, so as to ensure the reliability of the voltage testing grounding ring 2 on the insulated wire. It is especially suitable for areas that cannot be reached by live-line working vehicles, reducing the operational risks of manual climbing and adjustment.

[0035] This application further proposes that the driving component is a tension spring 5, with both ends of the tension spring 5 fixedly connected to the bottom of the two limiting rods 4 respectively. The main body 1 has a sliding groove along its own width direction for the limiting rods 4 to slide. The limiting rods 4 are provided with hooks 41, which extend out of the sliding groove for the tension spring 5 to connect.

[0036] The tension spring 5 is a helical component with axial elastic deformation capability, specifically made of spring steel. Its two ends are fixedly connected to the bottoms of the two limiting rods 4, generating a driving force that brings the limiting rods 4 closer together through its own contraction force. The bottom of the limiting rod 4 refers to the area near the mounting surface of the main body 1. Specifically, it can be a structure with a connecting ring welded to the end of the rod, used to constrain the connection position of the tension spring 5 and ensure that the direction of the tension force is consistent with the sliding trajectory. The hook 41 is a metal part with a bent structure, specifically a U-shaped protrusion 12 stamped on the outer surface of the limiting rod 4, extending outward through the opening in the side wall of the slide groove to form a fulcrum connecting to the end of the tension spring 5.

[0037] Specifically, after the grounding ring 2 is inserted into the groove, the contraction force of the tension spring 5 is transmitted to the two limiting rods 4 through the hook 41, driving them to slide along the slide groove towards the middle position until they clamp the two sides of the grounding ring 2. During this process, the elastic deformation of the tension spring 5 is positively correlated with the clamping force. After the grounding ring is clamped, the tension spring 5 maintains a preloaded state to prevent the limiting rods 4 from retracting. The guiding effect of the slide groove ensures that the limiting rods 4 move only along the width direction of the main body 1, avoiding deflection that could lead to clamping failure. The design of the hook 41 and the slide groove conceals the installation position of the tension spring 5, preventing external components from interfering with the operating space.

[0038] Compared with existing technologies, traditional clamping mechanisms often use manual tightening of bolts or complex gear transmission devices to drive the limit rod 4, which is not only cumbersome to operate but also prone to problems such as thread stripping and gear jamming. This solution achieves automatic clamping through the elastic restoring force of the tension spring 5, eliminating the need for continuous manual force application and significantly reducing the intensity of operation in confined spaces. The mating structure of the slide and hook 41 allows the entire drive system to be embedded inside the main body 1, avoiding the defects of external transmission components being susceptible to dust corrosion.

[0039] Through the above technical solution, this application achieves synchronous bidirectional motion control of the limiting rod 4, forming a stable clamping force on the surface of the insulated wire, avoiding the problem of piercing tooth misalignment caused by uneven manual crimping force. The adaptive drive of the tension spring 5 is compatible with different sizes of voltage testing grounding rings 2, and is suitable for complex working conditions such as narrow gaps between tower crossarms and inclined working surfaces, solving the technical obstacle that traditional live-line installation equipment is too bulky to enter mountainous work sites.

[0040] This application further proposes that the main body 1 has a groove along its own width for the sliding of the limiting rod 4, and the limiting rod 4 is provided with a hook 41, which extends out of the groove for connection with the tension spring 5.

[0041] The groove refers to the guide structure set in the width direction of the main body 1, which can be implemented by a T-shaped groove or a dovetail groove structure, and is used to constrain the movement trajectory of the limiting rod 4 and maintain sliding stability. The hook 41 refers to the connecting structure installed at the end of the limiting rod 4, which can be implemented by an L-shaped bent metal part or a ring buckle, and is used to transmit the traction force of the tension spring 5 to the limiting rod 4.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
