Description

Technical Field

[0001] This invention relates to the field of grounding wire hanging and removing technology, specifically a grounding wire hanging and removing device for substations. Background Technology

[0002] The installation and removal of substation grounding wires is an extremely important safety operation in the power system, which is directly related to the personal safety of the workers and the operational safety of the equipment. At present, the installation and removal of grounding wires mainly rely on manual climbing of towers. The whole process is time-consuming and laborious, and workers face great risks of falling from heights and electric shock while climbing towers.

[0003] Currently, while some simple devices or improved tools for assisting in the hanging and removal of grounding wires have emerged in existing technologies, these solutions generally suffer from problems such as complex structure, cumbersome operation, poor adaptability, or the need for close-range manual assistance. For example, some mechanical devices can only hang and remove grounding wires of a single size or at a specific location, and their versatility is significantly insufficient when dealing with grounding wires of different specifications and installation heights within substations.

[0004] Meanwhile, existing devices often fail to adequately consider rapid and accurate connection with grounding clamps and a stable clamping mechanism, resulting in limited improvement in installation efficiency. Furthermore, they pose a risk of loosening under equipment vibration or external force, making it difficult to meet the stringent requirements of power safety regulations for reliable grounding.

[0005] Therefore, there is an urgent need for a dedicated substation grounding wire hanging and removing device that can adapt to different working conditions, has multiple safety guarantees, and is highly efficient and reliable in hanging and removing grounding wires, so as to completely solve the safety risks and efficiency bottlenecks caused by manual operation.

[0008] Preferably, the connecting base is symmetrically provided with first bushings on both the front and rear sides, and a connecting rod is provided inside the first bushing. The connecting rod is connected to a power unit at one end of the connecting base. The power unit is a drive motor, and one side of the connecting rod can be rotated by an insulated handle.

[0009] Preferably, a transmission gear is fixedly installed on the connecting rod at the middle position of the bottom of the connecting base. The upper end of the transmission gear is meshed with a second worm gear. A second worm is provided on one side of the second worm gear. The upper end of the second worm is meshed with a first worm gear. The upper end of the first worm gear is meshed with a first worm.

[0010] Preferably, the first worm gear includes a lead screw, which is disposed on the top of the fixed block. Slider blocks are symmetrically disposed on both sides of the lead screw, and the sliders are fixedly disposed with the grounding clamp. Bearing seats are disposed at both ends of the lead screw.

[0011] Preferably, a limiting block is provided on the inner side of the fixing block near the lower end of the bearing seat, and the fixing block is engaged in the middle of the connecting plate by the limiting block.

[0012] Preferably, the connecting base is provided with connecting plugs on both the left and right sides, the connecting plugs are inserted into the connecting plate, and the connecting plugs pass through the connecting plate and are embedded in the connecting top seat.

[0013] Preferably, the connecting top seat is provided with a connecting groove corresponding to the connecting plug, and the connecting groove and the connecting plug are provided with a first connecting card and a second connecting card in a cross shape, with the first connecting card inserted into the second connecting card.

[0014] Preferably, the hanging assembly includes a hanging rod and a fixing pipe. The hanging rod includes a roller disposed inside the top and a limiting groove disposed on one side. A second bushing is fixedly disposed inside the limiting groove. A rotating rod is inserted into the second bushing. A limiting head is movably disposed inside the limiting groove on the rotating rod. A screw is disposed inside the fixing pipe on the hanging rod. A rotating component is fixedly disposed at the lower end of the screw. The bottom of the rotating component is configured with a spline structure.

[0015] Preferably, the fixed pipe fitting has a sliding cavity inside, and the hanging rod is slidably disposed in the sliding cavity.

[0016] Preferably, the grounding clamp has a sliding groove inside, a sliding rod is inserted through the sliding groove, a sliding plate is slidably mounted on the sliding rod, an arc-shaped clamp is fixedly mounted on the sliding plate, a grounding plate is provided on the inner side of the arc-shaped clamp, a conductor is connected to the grounding plate inside the sliding plate, and a grounding terminal is connected to a grounding terminal located at one end of the sliding plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses an embedded design of connecting plug and connecting groove between the connecting base and the connecting top seat, and is supplemented by a first connecting clip and a second connecting clip intersecting in a cross shape to achieve double locking. This modular design not only ensures the rigidity and stability of the overall structure of the connecting seat, but also facilitates the rapid assembly, disassembly and transportation of the device, thereby improving the efficiency of on-site deployment.

[0018] 2. This invention employs a telescopic structure in the mounting assembly. The mounting rod engages with the sliding cavity inside the fixed pipe via a screw. Rotating the rotating component drives the screw to rotate, thereby adjusting the extension length of the mounting rod within the fixed pipe. Simultaneously, the design of the rotating rod, second bushing, and limiting head within the limiting groove on one side of the mounting rod provides the limiting capability for the mounting rod to be installed on the substation grounding wire, achieving stable and reliable installation of the substation grounding wire device.

[0019] 3. This invention features an ingenious internal design for the grounding clamp. The sliding plate slides flexibly within the sliding groove via a sliding rod, adjusting the arc-shaped clamp to different heights. A power unit or manual operation linkage drives a transmission gear, which, through a transmission mechanism consisting of a second worm gear, a second worm, a first worm gear, and a first worm, ultimately drives the lead screw to rotate smoothly. This causes the symmetrically arranged sliders to move synchronously towards or away from each other, precisely driving the grounding clamp fixed to it, thus achieving the clamping or loosening of the arc-shaped clamp. A grounding plate on the inner side of the arc-shaped clamp ensures good contact between the device and the substation grounding, and the conductor reliably conducts current to the grounding terminal. This structure can adapt to the hanging and unhanging of grounding wires of different sizes, providing stable and reliable clamping force and effectively preventing loosening due to equipment vibration or external forces.

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1

[0023] like Figure 1-2 As shown in the figure, this embodiment discloses a substation grounding wire hanging and removing device, including a connecting seat, a hanging component 4 and a grounding clamp 5. The connecting seat includes a connecting base 1, a connecting plate 2 and a connecting top seat 3. The hanging component 4 is symmetrically arranged on the connecting plate 2. A fixing block 13 is connected to the lower end of the hanging component 4. The fixing block 13 is fixedly arranged on the connecting plate 2 and located between the hanging components 4. The connecting base 1 is arranged at the bottom of the connecting plate 2, and the connecting top seat 3 is arranged at the top of the connecting plate 2 corresponding to the connecting base 1.

[0024] In this embodiment, as Figure 1 As shown, the modular connecting base consisting of the connecting base 1, connecting plate 2, and connecting top seat 3, along with the symmetrically arranged hanging components 4 and adjustable grounding clamps 5, enable the device to be quickly assembled, disassembled, and stably supported.

[0025] In this embodiment, as Figure 2As shown, the grounding clamp 5 drives the transmission gear 24 through the power unit 25 or through the rotating operating linkage 23 of the insulating handle. Through the transmission mechanism composed of the second worm gear 21, the second worm 20, the first worm gear 19 and the first worm 18, the screw 15 is finally driven to rotate smoothly, so that the symmetrically arranged sliders 16 move synchronously towards or away from each other, thereby accurately driving the grounding clamp 5 fixed thereto, realizing the clamping or loosening action of the arc-shaped clamp 6, so as to adaptively clamp wires of different sizes. Meanwhile, the arc-shaped clamp 6 slides on the sliding rod 12 via the sliding plate 7 to adjust the arc-shaped clamp 6 to adapt to grounding wires of different heights. The grounding plate 10 on the inner side of the arc-shaped clamp 6 is tightly connected to the grounding terminal 8 through the conductor 9 to ensure low resistance conduction of the grounding circuit. Example 2

[0026] like Figure 1-5 As shown in the figure, this embodiment discloses a substation grounding wire hanging and removing device, including a connecting seat, a hanging component 4 and a grounding clamp 5. The connecting seat includes a connecting base 1, a connecting plate 2 and a connecting top seat 3. The hanging component 4 is symmetrically arranged on the connecting plate 2. A fixing block 13 is connected to the lower end of the hanging component 4. The fixing block 13 is fixedly arranged on the connecting plate 2 and located between the hanging components 4. The connecting base 1 is arranged at the bottom of the connecting plate 2, and the connecting top seat 3 is arranged at the top of the connecting plate 2 corresponding to the connecting base 1.

[0027] In this embodiment, as Figure 3 As shown, the mounting assembly 4 includes a mounting rod 31 and a fixing pipe 32. The mounting rod 31 includes a roller 26 disposed inside the top and a limiting groove 27 disposed on one side. A second bushing 29 is fixedly disposed inside the limiting groove 27. A rotating rod 28 is inserted into the second bushing 29. A limiting head 30 is movably disposed inside the limiting groove 27 of the rotating rod 28 to facilitate the introduction, mounting and limiting locking of substation grounding. A screw 34 is disposed inside the fixing pipe 32 of the mounting rod 31. A rotating part 35 is fixedly disposed at the lower end of the screw 34. A sliding cavity 33 is disposed inside the fixing pipe 32 to adjust the extension length of the mounting rod 31 inside the fixing pipe 32.

[0028] In this embodiment, as Figure 4 and 5 As shown, the embedded connection between the connector 39 and the connector slot 36, supplemented by the first connector 37 and the second connector 38 arranged in a cross shape, ensures a firm and reliable connection between the components of the connector and allows for quick assembly and disassembly.

[0029] Working principle: First, when the device is in operation, the operator first uses the quick engagement of the connecting plug 39 with the connecting slot 36, and then uses the first connecting clip 37 and the second connecting clip 38 in a cross shape to achieve a stable assembly of the connecting seat, ensuring the rigidity of the overall structure. When the grounding wire is installed, the rotating component 35 drives the screw 34 to rotate, so that the hanging rod 31 can be extended and adjusted in the sliding cavity 33 of the fixed pipe 32. The top roller 26 guides the grounding wire into the limiting groove 27. The rotating rod 28 and the limiting head 30 work together to lock the position of the grounding wire and prevent it from falling off. The power unit 25 or the manual rotation of the insulating handle drives the connecting rod 23, which in turn drives the transmission gear 24 to rotate. This is achieved by the speed reduction transmission mechanism consisting of the second worm wheel 21, the second worm 20, the first worm wheel 19, and the first worm 18, which causes the lead screw 15 to rotate smoothly and the symmetrical slider 16 to move synchronously. This, in turn, drives the grounding clamps 5 to move synchronously towards or away from each other. The arc-shaped clamp 6 adaptively clamps grounding wires of different sizes. The sliding plate 7 inside the grounding clamp 5 slides up and down along the sliding rod 12 in the sliding groove 11, so that its arc-shaped clamp 6 is adaptively aligned with the grounding wire at different heights, so that its grounding plate 10 is in close contact with the grounding wire, and the conductor 9 reliably conducts the current to the grounding terminal 8, achieving low resistance conduction. During disassembly, the reverse drive transmission mechanism releases the clamp and adjusts the hanging rod 31 to release the grounding wire. The entire process can be operated through the insulated rod without close human intervention, effectively avoiding the risks of falling from height and electric shock, and ensuring efficient and reliable hanging and disassembly.
