Description
Technical Field
[0001] This utility model belongs to the technical field of insulating rod fixing devices, specifically, it relates to a convenient fixing device for insulating rods used in live testing. Background Technology
[0002] In live-line testing, maintenance, and routine operation and maintenance of power systems, insulating rods serve as a core tool for achieving electrical isolation between live parts and operators. Their storage condition directly affects the stability of insulation performance, equipment lifespan, and operational safety. Insulating rods are typically made of insulating materials such as glass fiber reinforced epoxy resin. The surface insulation layer must be protected from impacts, scratches, or long-term pressure deformation; otherwise, it may lead to a decrease in insulation resistance, causing surface discharge or electric shock risks. Furthermore, the rapid retrieval and orderly storage of insulating rods at the testing site or in the warehouse are crucial for improving operational efficiency.
[0003] Currently, the main technical drawbacks of the current method of storing insulating rods are as follows: 1. Stacking on the ground or storing haphazardly: Insulating rods are prone to bending and deformation due to mutual compression caused by their own weight, and the surface insulation layer is easily scratched by collisions and friction. Especially in multi-person operation scenarios, disorderly stacking of insulating rods can lead to light obstruction and difficulty in searching when they are needed, and may even require multiple people to work together to move them, which seriously affects work efficiency.
[0004] 2. Limitations of Traditional Fixed Hangers: Existing hangers mostly use a structure with parallel upper and lower layers of the same diameter, requiring the insulating rod to be vertically snapped into the limiting device. This design has three major problems: First, poor compatibility, as the fixed buckle spacing and diameter cannot accommodate insulating rods of different lengths, resulting in insufficient versatility; second, cumbersome operation, requiring operators to precisely align the upper and lower buckles when placing the rod vertically, and long rods are prone to tipping over due to their high center of gravity, necessitating repeated adjustments during placement, and overcoming the dual resistance of the upper and lower buckles when retrieving them, especially for long rods, making single-person operation laborious and prone to collisions.
[0005] There is a gap in the optimization of existing rotating racks: Although rotating racks solve the problem of direction adjustment, they are not designed for the tilting posture of the insulating rod, the force logic of the buckle, and the matching of the upper and lower structure. As a result, there are still problems such as difficulty in aligning the insulating rod when placing it and excessive buckle constraint when taking it out, which cannot meet the flexible and ever-changing storage needs.
[0006] In summary, existing insulating rod storage devices have significant shortcomings in terms of safety (insulation layer protection), compatibility (multi-specification adaptation), and convenience (retrieval efficiency). This results in disordered storage, time-consuming retrieval, and high equipment wear and tear, making it difficult to meet the high efficiency and safety requirements of power operations. Therefore, developing a fixing device that enables stable storage, convenient retrieval, and compatibility with multiple specifications of insulating rods has become an urgent technical problem to be solved in this field. Utility Model Content
[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a convenient fixing device for an insulating rod for live testing that can overcome or at least partially solve the above problems.
[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a convenient fixing device for an insulating rod for live testing, including a column, and further including: an upper frame, rotatably mounted on the column; a lower frame, rotatably mounted on the column, the upper frame and the lower frame being connected by a connector, the outer diameter of the upper frame being larger than that of the lower frame, so that an inwardly converging area is formed between the upper frame and the lower frame; locking members, respectively circumferentially connected to the upper frame and the lower frame, and multiple locking members being provided; and limiting buckles connected to the locking members, the limiting buckles forming an adjustable clamping area, capable of adaptively clamping insulating rods of different specifications.
[0009] Preferably, both the upper and lower shelves are fixedly connected to connecting rods, which converge at the center of the upper and lower shelves respectively and are fixedly connected to collars, which are sleeved on the columns.
[0010] Preferably, a locking ring is fitted onto the column for locking connection. The locking ring is located above the collar of the upper shelf and below the collar of the lower shelf, respectively, to limit the movement of the upper shelf and the lower shelf.
[0011] Preferably, the locking component includes an arc-shaped part and a mounting plate. The arc-shaped part is sleeved on the upper shelf and the lower shelf. The arc-shaped part and the mounting plate are integrally formed. The arc-shaped part is connected to the upper shelf and the lower shelf by bolts.
[0012] Preferably, the limiting buckle includes a mounting panel, bending arms, and rubber wheels. The mounting panel is connected to a mounting plate. The bending arms are symmetrically arranged on both sides of the mounting panel, and the angle between the bending arms and the mounting panel is less than 1 degree. The rubber wheels are rotatably connected to the two bending arms respectively.
[0013] Preferably, the bending arm is provided with a folding mounting part that folds inward, the rubber wheel is located on the folding mounting part, and a wave groove is provided on the inner side of the folding mounting part.
[0014] Preferably, a rubber pad is provided on the other side of the mounting panel.
[0015] Preferably, the connector is a rod, and both ends of the rod are fixedly connected to connecting rods on the upper and lower shelves, respectively.
[0016] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: 1. This portable fixing device for insulating rods used in live-line testing features an inward-converging area created by the difference in diameter between the upper and lower shelves, allowing the insulating rods to be stored at an angle. When placing the rods, they can be sequentially engaged with the upper and lower latches along the natural force trajectory. When retrieving the rods, they can be unlocked step by step (lower first, then upper), reducing vertical alignment and double resistance. The device can be operated by a single person, reducing labor intensity. At the same time, the device can store insulating rods in an orderly manner, and the spacing between the rods ensures that they are stored separately, preventing contact and collision.
[0017] 2. The convenient fixing device for the insulating rod used in the live-line test has an adjustable clamping area for the limit buckle, which can adaptively clamp insulating rods of different specifications through the elastic deformation of the rubber wheel and the bending arm.
[0018] 3. The convenient fixing device for the insulating rod used in live testing features rubber wheels, rubber pads, and corrugated grooves with limit buckles to prevent hard contact between the insulating rod and metal parts, reducing surface scratches; tilted storage stabilizes the center of gravity of the insulating rod, reducing the risk of collision; and the rubber material enhances friction to prevent accidental slippage.
[0019] 4. This convenient fixing device for insulating rods used in live-line testing features a design with a difference in diameter between the upper and lower shelves, along with an inclined design for the limiting buckles. This design ensures that the process of removing and placing the rod involves first unlocking the lower shelf and then unlocking the upper shelf. Because the lower shelf has a smaller diameter, the lower end of the insulating rod is closer to the column. The operator can first concentrate their force to pull the lower end of the insulating rod away from the limiting buckle on the lower shelf. At this time, the limiting buckle on the upper shelf, due to its larger diameter and outward position, and its downward tilt, causes the insulating rod to naturally tilt outward under the action of gravity and tension. The constraint of the upper shelf's limiting buckle is automatically released without additional force, achieving a smooth experience of one-step pulling and two-step unlocking. This avoids the jamming problem that traditional vertical racks require overcoming the resistance of the upper and lower buckles simultaneously when removing and placing the rod.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0024] Example: Refer to Figures 1-6 A convenient fixing device for an insulating rod used in live-line testing includes a column 1, a counterweight base plate 10 installed at the end of the column 1, an upper shelf 11, a lower shelf 12, a locking element 3, and a limiting buckle 4; wherein: The column 1 is a cylindrical metallic or insulating composite material rod with a counterweight base plate 10 fixedly connected to the bottom to prevent the device from tipping over by increasing the weight at the bottom. The upper part of the column 1 is fitted with a rotatable upper shelf 11 and a lower shelf 12, which are spaced apart along the axial direction of the column 1. The spacing is designed according to the length of the insulating rod 2, preferably 0.8-1.2m.
[0025] Upper shelf 11 and lower shelf 12: Both are circular frames. The outer diameter of the upper shelf 11 is larger than that of the lower shelf 12, forming an inwardly converging area 6 between the upper shelf 11 and the lower shelf 12. The upper shelf 11 and the lower shelf 12 are both fixed to the collar 112 by connecting rods 111 and ferrules 112. The connecting rods 111 are arranged radially, with one end fixed to the outer circumference of the upper shelf 11 / lower shelf 12, and the other end converging towards the center and welded or bolted to the collar 112. The collar 112 is fitted onto the column 1, enabling the upper shelf 11 and the lower shelf 12 to rotate 360° around the column 1. The column 1 is also fitted with locking rings 13, located above the collar 112 of the upper shelf 11 and below the collar 112 of the lower shelf 12. The locking rings 13 can be fixed to the column 1 by tightening the radial bolts, thereby fixing the height of the upper shelf 11 and the lower shelf 12 on the column 1.
[0026] Connector 14: Used to connect the upper shelf 11 and the lower shelf 12, enhancing the overall structural stability. Connector 14 is a rod (see reference). Figure 3 The two ends are welded and fixed to the connecting rods 111 of the upper frame 11 and the lower frame 12, respectively.
[0027] Locking component 3: evenly distributed along the outer circumference of the upper shelf 11 and the lower shelf 12 (the number is set according to the requirements, preferably 6-8). The locking component 3 includes an arc-shaped part 31 and a mounting plate 32. The arc-shaped part 31 matches the outer circumference arc of the upper shelf 11 / lower shelf 12 and is fixed to the upper shelf 11 / lower shelf 12 by means of bolt clamping or bolt passing through the upper shelf 11 / lower shelf 12. The mounting plate 32 is located on the arc-shaped part 31. The mounting plate 32 can be welded to the arc-shaped part 31, bolted, or integrally formed. The mounting plate 32 is used to connect the limiting buckle 4.
[0028] The limiting buckle 4 is fixed on the mounting plate 32 and includes a mounting panel 41, a bending arm 42, rubber wheels 43, and rubber pads 44. The mounting panel 41 is connected to the mounting plate 32 by bolts; the bending arms 42 are symmetrically arranged on both sides of the mounting panel 41, forming an angle of less than 90° (preferably 60°-75°) with the mounting panel 41, and their ends are folded inward to form a folding mounting part 45; the rubber wheels 43 are rotatably connected to the folding mounting part 45 by a shaft pin, and an adjustment clamping area 40 is formed between the two rubber wheels 43. Through the elastic deformation and rotation characteristics of the rubber wheels 43 and the metal elasticity of the bending arms 42, the insulating rods 2 of different diameters (30mm-60mm) are adaptively clamped; the inner side of the folding mounting part 45 is provided with a wave groove 46 to enhance the friction with the insulating rods 2 and prevent slippage; a rubber pad 44 is pasted on the side of the mounting panel 41 away from the bending arm 42 to avoid scratches caused by hard contact between the insulating rods 2 and the mounting panel 41. To further prevent the limiting buckle 4 from damaging the insulating rod 2, protective strips such as cloth strips and rubber strips can be wrapped around the limiting buckle 4 for protection.
[0029] In use, this device utilizes the difference in diameter between the upper shelf 11 and the lower shelf 12, along with the tilting design of the limiting buckle 4, to facilitate the convenient placement and stable storage of the insulating rod. The specific process is as follows: Storage process: The operator aligns the middle part of the insulating rod 2 with the limiting buckle 4 of the upper shelf 11 and pushes it into the adjusting clamping area 40 along the inclined direction (towards the column 1). After the rubber wheel 43 is squeezed, the bending arm 42 automatically opens, and the upper part of the insulating rod 2 is initially fixed by friction. Then, the palm slides down along the insulating rod 2, pushing its lower part to move inward into the contraction area 6, so that the lower end enters the corresponding limiting buckle 4 of the lower shelf 12. The rubber wheel 43 and the bending arm 42 automatically clamp again, completing the storage. At this time, the insulating rod 2 is in an inclined state (angle with the column 1 65°-80°). The end of the insulating rod 2 forms a contraction layer 7, while the upper end of the insulating rod 2 forms an outward expansion layer 8, which can effectively prevent the working heads at the front end of the insulating rod from getting close to each other and causing collisions.
[0030] Retrieval process: The operator holds the lower end of the insulating rod 2 and pulls it outward. The rubber wheel 43 in the limiting buckle 4 of the lower shelf 12 rotates with the insulating rod 2, reducing frictional resistance and allowing the lower end to quickly disengage from the adjustment clamping area 40. Since the upper shelf 11 has a larger diameter and the limiting buckle 4 is tilted, the insulating rod 2 naturally tilts when pulled outward. Under the guidance of the rubber wheel 43, the upper part disengages from the upper limiting buckle 4, enabling quick retrieval by a single person.
[0031] Therefore, the difference in diameter between the upper shelf 11 and the lower shelf 12, combined with the inclined design of the limiting buckle 4, makes the process of taking and placing items a clear step of first unlocking the lower shelf and then unlocking the upper shelf. Because the lower shelf has a smaller diameter, the lower end of the insulating rod 2 is closer to the column 1. The operator can first concentrate the force to pull the lower end of the insulating rod 2 away from the limiting buckle 4 on the lower shelf 12. At this time, the limiting buckle 4 of the upper shelf 11 has a larger diameter, is located further out, and is inclined downwards. Under the action of gravity and tension, the insulating rod 2 naturally tilts outwards, and the constraint of the upper shelf limiting buckle 4 is automatically released without additional force. This achieves a smooth experience of pulling in one step and unlocking in two steps, avoiding the jamming problem of having to overcome the resistance of the upper and lower buckles at the same time when taking and placing items on traditional vertical racks.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
