Description

Technical Field

[0001] This utility model belongs to the field of auxiliary operation platform technology, specifically relating to an auxiliary operation platform for replacing high-altitude insulators. Background Technology

[0002] The high-altitude insulator replacement auxiliary operation platform is a special equipment used in the maintenance of power transmission lines. It is mainly used to safely and efficiently replace insulators on high-altitude transmission lines.

[0003] Existing auxiliary operating platforms for replacing high-altitude insulators, such as the invention disclosed in patent number CN201656337U, include seven major components: a personnel seating platform, a cup-head retaining ring, a platform main frame, an operating handle, a lateral telescopic cantilever, a retaining ring cantilever, and a retaining ring pin. The platform is characterized by: lateral telescopic cantilever connected to the front and rear of the operating platform; the other end of each lateral telescopic cantilever connected to a retaining ring cantilever via the platform main frame; and a cup-head retaining ring connected to each end of the retractable retaining ring cantilever located in the slots of the platform main frame and the operating handle. Each cup-head retaining ring and retaining ring pin form a structure fixed to the insulator cup head.

[0004] The existing auxiliary operation platform for replacing high-altitude insulators has a complex structure, is not suitable for replacing insulators of different intervals, and is not convenient for installation and disassembly at high altitudes, posing significant safety hazards to workers. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary operating platform for replacing high-altitude insulators, which can improve the ease of operation, enhance the applicability and flexibility of the platform, and is suitable for insulator maintenance operations under different working conditions.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An auxiliary operating platform for replacing high-altitude insulators includes a seating platform. Two first telescopic rods are installed through the seating platform. Two pairs of first limiting devices are provided on the side walls of the seating platform. Two second limiting devices are fixed to both ends of each first telescopic rod. A second telescopic rod is installed through the two second limiting devices. The lengths of the first telescopic rods and the second telescopic rods are adjustable. Two locking devices are fixed to both ends of each second telescopic rod.

[0008] Preferably, the seating platform is provided with a plurality of anti-slip columns, which are distributed in an array at equal intervals.

[0009] Preferably, the outer wall of the seating platform has a first circular hole, and the first limiting device includes a first nut installed on the outer wall of the seating platform. The first nut is bolted with a first bolt, and the end of the first bolt passes through the side wall of the seating platform and fits against the surface of the first telescopic rod.

[0010] Preferably, the second limiting device includes a limiting block connected to the end of the first telescopic rod, a second nut fixed to the upper end of the limiting block, a second bolt bolted to the second nut, and the second bolt passing through the upper surface of the limiting block.

[0011] Preferably, the locking device includes two fixing blocks installed at the end of the second telescopic rod, with locking clamps hinged to the ends of the two fixing blocks. A third nut is rotatably connected to the end of one of the locking clamps, and a U-shaped opening is provided at the end of the other locking clamp. A third bolt is bolted to the third nut, and the third bolt is adapted to the U-shaped opening at the end of the locking clamp.

[0012] Preferably, the second telescopic rod includes an outer section rod and an inner section rod. A second circular hole is provided at both ends of the outer section rod. The inner section rod can reciprocate inside the outer section rod. The second bolt passes through the second circular hole.

[0013] Preferably, the first bolt, the second bolt, and the third bolt are equipped with handles.

[0014] The technical effects achieved by this utility model are as follows:

[0015] In this utility model, the insulator auxiliary operating platform is mainly used for the installation, replacement, inspection, or maintenance of insulators in power systems during high-altitude operations. Through a locking device, during operation, the worker opens the locking clamp and secures it to the cup heads of two insulator strings. A third bolt enters the U-shaped opening at the end of the locking clamp, with one surface of the third bolt fitting against the end surface of the other locking clamp. By rotating the third bolt, one locking clamp is pressed, causing the two clamps to move closer together, thus achieving a stable clamping and locking of the insulator cup heads. In practical applications, since the spacing between the two insulator strings may differ, the inner section of the inner section can freely extend and retract within the outer section through the telescopic adjustment of the second telescopic rod. A second circular hole is provided at both ends of the outer section rod. When adjusted to the required length, simply rotate the second bolt to pass it through the second round hole of the outer section rod and directly press it against the surface of the inner section rod. The strong compressive force generated by the bolt achieves quick locking, ensuring both the flexibility of length adjustment and the structural stability after fixing. This allows the platform to adapt to different spacing requirements and improves the universal applicability of the replacement auxiliary operation platform. After installation, workers can sit on the seating platform to perform operations. The seating platform can slide on the first telescopic rod, making it easy to adjust to the corresponding position for insulator replacement, improving operational convenience, enhancing the platform's applicability and flexibility, and making it suitable for insulator maintenance operations under different working conditions.

Detailed Implementation

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] An auxiliary operating platform for replacing high-altitude insulators includes a seating platform 1, in which two first telescopic rods 2 are installed through. Two pairs of first limiting devices 3 are provided on the side walls of the seating platform 1. Two second limiting devices 4 are fixed to both ends of each first telescopic rod 2. A second telescopic rod 5 is installed through between the two second limiting devices 4. The lengths of the first telescopic rods 2 and the second telescopic rods 5 are adjustable. Two locking devices 6 are fixed to both ends of each second telescopic rod 5.

[0024] like Figures 1-4 As shown: In high-altitude operations, the insulator auxiliary operating platform is mainly used for the installation, replacement, inspection, or maintenance of insulators in power systems. Through the locking device 6, during operation, the worker opens the locking clamp 602, securing it to the cup heads of two strings of insulators. Rotating the third bolt 603 reduces the distance between the two locking clamps 602 until the third nut 604 is rotated to the appropriate position, ensuring a secure lock. In practical applications, since the distance between the two strings of insulators may differ, the platform can be adjusted using the extension and retraction of the second telescopic rod 5 to adapt to different distance requirements, improving the versatility of the replacement auxiliary operating platform. After installation, the worker can sit on the seating platform 1 to perform the work. The seating platform 1 can slide on the first telescopic rod 2, facilitating adjustment to the corresponding position for insulator replacement, improving operational convenience, and enhancing the platform's applicability and flexibility, making it suitable for insulator maintenance operations under different working conditions.

[0025] Preferably, the seating platform 1 is provided with a number of anti-slip columns 101, which are distributed in an array at equal intervals.

[0026] like Figures 1-4 As shown: Workers must sit on the seating platform 1 to perform high-altitude operations. Since the positions of the two insulator strings are not necessarily horizontally aligned, the seating platform 1 may not remain level, posing a safety hazard. To enhance stability, anti-slip posts 101 are installed in an equally spaced array inside the seating platform 1. By increasing the friction between the platform and the worker, the safety and stability during operation are effectively improved.

[0027] Preferably, the outer wall of the seating platform 1 has a first circular hole, and the first limiting device 3 includes a first nut 302 installed on the outer wall of the seating platform 1. The first nut 302 is bolted with a first bolt 301, and the end of the first bolt 301 passes through the side wall of the seating platform 1 and is in contact with the surface of the first telescopic rod 2.

[0028] like Figures 1-4 As shown: While the seating platform 1 slides back and forth on the first telescopic rod 2, the seating platform 1 needs to be fixed so that the staff can work. When the seating platform 1 is slid to the appropriate position, the first nut 302 is rotated. The first nut 302 passes through the side wall of the seating platform 1 and matches the first round hole to ensure that the seating platform 1 is stable.

[0029] Preferably, the second limiting device 4 includes a limiting block 401 connected to the end of the first telescopic rod 2, a second nut 403 fixed to the upper end of the limiting block 401, a second bolt 402 bolted to the second nut 403, and the second bolt 402 passing through the upper surface of the limiting block 401.

[0030] like Figures 1-4 As shown: In practical applications, the second telescopic rod 5 is adjusted in length to accommodate two strings of insulators with different spacing. Once adjusted to the appropriate length, it is fixed by the second limiting device 4. The second bolt 402 is rotated so that its end abuts against the surface of the inner section rod 502, and the clamping force of the bolt is used to achieve a stable lock, ensuring that the operating platform remains stable during operation.

[0031] Preferably, the locking device 6 includes two fixing blocks 601 installed at the end of the second telescopic rod 5. The ends of the two fixing blocks 601 are hinged with locking clips 602. One locking clip 602 is rotatably connected to the end of one locking clip 604. The other locking clip 602 has a U-shaped opening at its end. The third nut 604 is bolted with a third bolt 603. The third bolt 603 is adapted to the U-shaped opening at the end of the locking clip 602.

[0032] like Figures 1-4 As shown: During operation, the locking clamp 602 is opened and locked onto the cup head of the two strings of insulators. The third bolt 603 enters the U-shaped opening at the end of the locking clamp 602. One surface of the third bolt 603 is in contact with the end surface of the other locking clamp 602. By rotating the third bolt 603, one of the locking clamps 602 is squeezed, causing the two locking clamps 602 to come closer together, thereby achieving a stable clamping of the insulator cup head and ensuring the stability and safety of the operating platform when working at height.

[0033] Preferably, the second telescopic rod 5 includes an outer section rod 501 and an inner section rod 502. A second circular hole is provided at both ends of the outer section rod 501, and the inner section rod 502 can reciprocate inside the outer section rod 501. The second bolt 402 passes through the second circular hole.

[0034] like Figures 1-4 As shown: A second circular hole is provided at both ends of the outer section rod 501, allowing the inner section rod 502 to extend and retract freely within the outer section rod 501. When adjusted to the desired length, simply rotate the second bolt 402 to pass it through the second circular hole of the outer section rod 501 and directly press it against the surface of the inner section rod 502. The strong compressive force generated by the bolt achieves rapid locking, ensuring both the flexibility of length adjustment and the structural stability after fixing.

[0035] Preferably, the first bolt 301, the second bolt 402 and the third bolt 603 are equipped with handles.

[0036] like Figures 1-4 As shown: In practical applications, bolts are typically used to secure or limit the device. However, when working at heights, directly rotating the bolts is inconvenient and poses safety hazards. Therefore, a special handle was added to one end of each bolt, allowing the bolt to be rotated by turning the handle. This improvement not only makes operation more convenient and efficient but also significantly reduces the safety risks associated with working at heights.

[0037] The working principle of this utility model is as follows: In high-altitude operations, the insulator auxiliary operating platform is mainly used for the installation, replacement, inspection, or maintenance of insulators in power systems. Through the locking device 6, during operation, the worker opens the locking clamp 602 and clamps it onto the cup heads of two strings of insulators. The third bolt 603 enters the U-shaped opening at the end of the locking clamp 602, with one surface of the third bolt 603 fitting against the end surface of the other locking clamp 602. By rotating the third bolt 603, one locking clamp 602 is pressed against it, causing the two locking clamps 602 to move closer together, thus achieving a stable clamping of the insulator cup heads and ensuring a secure lock. In practical applications, since the spacing between the two strings of insulators may be different, the second telescopic rod 5 is adjusted by extending and retracting. A second round hole is provided at both ends of the outer section rod 501, allowing the inner section rod 502 to freely extend and retract within the outer section rod 501. When adjusted to the required length, simply rotate the second bolt 402 to pass it through the second round hole of the outer section rod 501 and directly press it against the surface of the inner section rod 502. The strong squeezing force generated by the bolt achieves quick locking, ensuring both the flexibility of length adjustment and the structural stability after fixing. This allows the platform to adapt to different spacing requirements and improves the universal applicability of the replacement auxiliary operation platform. After installation, the operator can sit on the seating platform 1 to perform the work. The seating platform 1 can slide on the first telescopic rod 2, making it easy to adjust to the corresponding position for insulator replacement, improving operational convenience, enhancing the applicability and flexibility of the platform, and making it suitable for insulator maintenance operations under different working conditions.
