Description

Technical Field

[0001] This application belongs to the field of bypass indirect operation technology, specifically relating to a bypass operation method for an insulating pole. Background Technology

[0002] Bypass work is the most complex and crucial type of live-line work, and flexible bypass cables are essential equipment for conducting such work. Currently, there are two main methods for live-line work: direct work, where workers need to directly contact the live conductor (this is the mainstream method), and indirect work, where workers do not need to directly contact the live conductor but instead use an insulated rod. However, the flexible cables involved in bypass work are heavy, and the resistance encountered when using an insulated rod is significant, making it difficult to accurately control. This hinders the development of an insulated rod bypass work technology to ensure both worker efficiency and safety. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] In view of this, an insulated rod bypass operation method is proposed according to an embodiment of this application, including: Install the support device inside the insulated bucket of the insulated bucket truck; Multiple flexible cables are installed onto the support device; The insulated bucket is lifted to the vicinity of the working position using an insulated bucket truck, so that the cable head is suspended in the air; Use an insulating rod to clamp and lift the cable head to the work position; Perform live-line connection work.

[0005] In one feasible implementation, installing the support device inside the insulated bucket of the insulated bucket truck includes the following steps: The support device is hoisted into the insulated bucket of another insulated bucket truck using the small boom of the insulated bucket truck.

[0006] In one feasible implementation, installing the support device into the insulated bucket of the insulated bucket truck further includes the step of: The support device is manually moved and placed directly into the insulated bucket.

[0007] In one feasible implementation, the bottom of the support device is embedded in the insulating hopper, and the support device is fastened to the insulating hopper by a fixing module.

[0008] In one feasible implementation, the support device includes a limiting box and a fixing module. The fixing module is disposed on the outer wall of the limiting box and includes an overlapping plate, an elongated hole and fastening bolts. The overlapping plate is fixed to the outer wall of the support device and has an elongated hole. The steps include embedding the bottom of the support device into the insulating hopper and securing the support device to the insulating hopper using a fixing module: Make the limiting box embed into the insulating hopper; Make the overlapping plate overlap the platform of the insulating bucket; Adjust the position of the limit box inside the insulating hopper; After the fastening bolt passes through the elongated hole, it is threaded into the platform of the insulating bucket.

[0009] In one feasible implementation, mounting multiple flexible cables to a support device includes the steps of: The support device is installed inside the insulated bucket of an insulated bucket truck. On the ground, all the flexible cables are installed on the support device inside the insulated bucket of this insulated bucket truck; The worker was standing inside the insulated bucket of another insulated bucket truck. Two insulated bucket trucks were used to lift the personnel working at height and the flexible cables, respectively.

[0010] In one feasible implementation, when using insulating rods to clamp and lift the cable head to the working position, the height and distance of the insulating buckets of the two insulating bucket trucks are constantly adjusted.

[0011] In one feasible implementation, multiple flexible cables are clamped onto a support device by a cable clamping mechanism.

[0012] In one feasible implementation, the clamping mechanism includes an extension rod and a plurality of clamping heads. The extension rod is connected to a support device and is disposed outside the insulating hopper. The extension rod extends along the length of the insulating hopper, and the clamping heads are detachably connected to the extension rod. Multiple flexible cables are clamped onto the support device using a cable clamping mechanism, including the following steps: Fix multiple flexible cables one by one to the clamping head; The clamping head clamps the middle of the flexible cable; Allow the cable head to hang down naturally, ensuring it is below the lowest point of the insulation hopper.

[0013] In one feasible implementation, an insulating rod is used to attach the flexible cable to the corresponding overhead live conductor.

[0014] The bypass operation method for insulating poles proposed in this application has the following advantages compared with the prior art: The insulated rod bypass operation method provided in this application integrates a dedicated support device inside the insulated bucket and utilizes a general-purpose insulated bucket truck as a dedicated aerial platform for lifting and supporting flexible cables. Most of the cable's self-weight and external load are transferred to the bucket truck through the support device and the insulated bucket, eliminating the need for overhead conductors to bear the entire cable weight. Simultaneously, by controlling the bucket truck, multiple cables can be hoisted and positioned synchronously in space, allowing operators to flexibly adjust the cable connection points in a single operation, significantly shortening operation time and reducing labor intensity and aerial operation risks. After the cable is hoisted, the cable head is suspended in the air by the support device. Because the support device supports the cable, its weight is reduced, allowing operators to easily use the insulated rod to complete the live connection of the flexible cable. This improves the standardization and applicability of complex bypass operations and enables indirect operation, eliminating the need for direct contact with live conductors. By using the insulated rod, operator safety is greatly ensured. Attached Figure Description

[0019] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] like Figure 1 and Figure 2 As shown, according to an embodiment of this application, a bypass operation method for an insulating rod is proposed, comprising: Step 100: Install the support device 1 into the insulated bucket of the insulated bucket truck; Step 200: Install multiple flexible cables 2 onto the support device 1; Step 300: Use an insulated bucket truck to lift the insulated bucket to the vicinity of the working position, so that the cable head is suspended in the air; Step 400: Use insulating rod 3 to clamp and lift the cable head to the working position; Step 500: Perform live connection work.

[0021] The bypass operation method using the insulating rod 3 provided in this application integrates a dedicated support device 1 inside the insulating bucket and utilizes a general-purpose insulating bucket truck as a dedicated aerial platform for lifting and supporting the flexible cable 2. Most of the cable's self-weight and external load are transferred to the bucket truck via the support device 1 and the insulating bucket, eliminating the need for the overhead conductor 4 to bear the entire weight of the cable. Simultaneously, by controlling the bucket truck, multiple cables can be simultaneously and mechanically lifted and spatially positioned, allowing operators to flexibly adjust the cable connection points in a single operation, significantly shortening operation time and reducing labor intensity and aerial operation risks. After the cable is lifted, the cable head is suspended in the air by the support device 1. Because the support device 1 supports the cable, its weight is reduced, allowing operators to easily use the insulating rod 3 to complete the live connection of the flexible cable 2. This improves the standardization and applicability of complex bypass operations and enables indirect operation, eliminating the need for direct contact with live conductors. The use of the insulating rod 3 greatly ensures operator safety.

[0022] In one feasible implementation, the support device 1 is installed inside the insulating bucket of the insulating bucket truck, including the following steps: The support device 1 is hoisted into the insulated bucket of another insulated bucket truck using the small boom of one insulated bucket truck.

[0023] In this technical solution, the small boom function of the insulated bucket truck, which is often overlooked, is used to lift the support device 1. The lifting process of the small boom is stable and controllable, avoiding the risk of equipment collision or personnel sprains that may be caused by manual handling. It is suitable for complex environments such as urban areas and fields where construction site space is limited and the access of lifting equipment is inconvenient, and it can better adapt to harsh site conditions. At the same time, there is no need to introduce additional heavy machinery such as truck cranes and forklifts, which reduces the equipment complexity and traffic support pressure of on-site operations.

[0024] In one feasible implementation, installing the support device 1 into the inside of the insulating bucket of the insulating bucket truck further includes the step of: The support device 1 is manually moved and placed directly into the insulated bucket.

[0025] In this technical solution, the support device 1 has a simple structure and can be manually transported and installed, ensuring the universality of the operation method under extreme or special conditions. When the boom truck is not equipped with a small boom, the small boom is faulty, or the site space is extremely limited, the manual handling and installation ensures that the operation method can be started smoothly under any circumstances, without the need for any special tools, thus reducing the technical threshold and equipment dependence of the operation.

[0026] In one feasible implementation, the bottom of the support device 1 is embedded in the insulating hopper, and the support device 1 is fastened to the insulating hopper by a fixing module.

[0027] In this technical solution, the support device 1 is embedded in the insulating bucket, and the support device 1 is rigidly locked by the fixed module to ensure that the support device 1 and the insulating bucket form a high-load-bearing overall working unit, which can support more flexible cables 2. This ensures that the cable's own weight, wind load and working dynamic load are safely transferred to the robust metal structure of the insulating bucket truck, avoiding serious high-altitude operation risks such as the overturning of the support device 1 and cable slippage caused by unreliable connection, and ensuring the stability and safety of high-altitude operations.

[0028] In one feasible embodiment, the support device 1 includes a limiting box and a fixing module. The fixing module is disposed on the outer wall of the limiting box. The fixing module includes an overlapping plate, an elongated hole and fastening bolts. The overlapping plate is fixed to the outer wall of the support device 1 and has an elongated hole. The steps include: embedding the bottom of the support device 1 into the insulating hopper, and fastening the support device 1 to the insulating hopper using a fixing module; Make the limiting box embed into the insulating hopper; Make the overlapping plate overlap the platform of the insulating bucket; Adjust the position of the limit box inside the insulating hopper; After the fastening bolt passes through the elongated hole, it is threaded into the platform of the insulating bucket.

[0029] In this technical solution, a gap exists between the outer wall of the limiting box and the inner wall of the insulating hopper to form an embedded structure with a gap. This provides a certain tolerance space for the embedding and initial positioning of the limiting box, making the installation process smoother and eliminating the need for absolutely precise alignment. This reduces the difficulty of on-site operation and makes the assembly and disassembly of the limiting box more convenient. Simultaneously, because the limiting box is an embedded structure, even if it is not fixedly connected to the insulating hopper, it will not tip over due to the weight of the cable or fall due to detachment from the insulating hopper, providing secondary protection for the device and operators and enhancing the overall safety of the device. Bolts pass through elongated holes and connect to the platform of the insulating hopper, allowing the limiting box to be detachably installed on the insulating hopper, improving the structural stability of the device and preventing movement or tipping during operation. By setting elongated holes in the overlapping plate, the overlapping plate can be adjusted within a certain range when the bolts are not tightened, so that the limiting box does not need to be precisely aligned with the insulating hopper when fixed. This also allows the device to adapt to insulating hoppers of different models or slightly different sizes, improving the versatility and adaptability of the device.

[0030] like Figure 2 As shown, in one feasible embodiment, mounting multiple flexible cables 2 onto the support device 1 includes the following steps: Install the support device 1 inside the insulated bucket 7 of the first insulated bucket truck; On the ground, all the flexible cables 2 are installed on the support device 1 inside the insulating bucket 7 of the first insulating bucket truck; The workers at height are standing inside the insulated bucket 8 of the second insulated bucket truck; Two insulated bucket trucks were used to lift the personnel working at height and the flexible cables, respectively.

[0031] In this technical solution, the cable is lifted by the first insulated bucket truck 5, and the operator is lifted by the second insulated bucket truck 6. This allows the bucket truck carrying the cable to focus on large-scale movement and precise positioning based on the connection point, while the bucket truck carrying the operator can be flexibly adjusted to the optimal observation and operation angle. This solves the safety hazards of crowded working space, excessively high center of gravity, and mutual interference caused by the mixing of people and materials inside the insulated bucket when operating with a single bucket. It helps to improve the safety and reliability of high-altitude live-line work. At the same time, the cooperation of two bucket trucks can reduce the load on the insulated bucket of a single bucket truck, thereby further improving the safety of bypass operations.

[0032] In one feasible implementation, when using the insulating rod 3 to clamp and lift the cable head to the working position, the height and distance of the insulating buckets of the two insulating bucket trucks are constantly adjusted.

[0033] In this technical solution, by adjusting the height, horizontal distance, and angle of the insulating buckets of the two bucket trucks respectively, the heavy cable is delivered to the area in front of the operator that is most labor-saving and most in line with the operator's operating habits. This reduces the physical exertion and operational difficulty for the operator when using the long insulating rod 3 to lift, pull, and connect the cable. It helps to improve the success rate and efficiency of the connection operation and reduce the risk of misoperation due to fatigue.

[0034] In one feasible implementation, multiple flexible cables 2 are clamped onto the support device 1 by a cable clamping mechanism.

[0035] In this technical solution, the cable clamping mechanism provides an efficient and standardized physical interface for the parallel management of multiple cables, realizing a standardized process for cable clamping operations. This allows ground support personnel to quickly clamp multiple cables into their fixed positions, ensuring that the cables are clamped securely and neatly. This avoids problems such as cables becoming entangled, slipping, or having their insulation layer damaged due to insecure fixing during lifting, and prevents cables from shifting or loosening due to contact with the insulating rod 3, thus ensuring the stability of the cables after lifting.

[0036] In one feasible embodiment, the clamping mechanism includes an extension rod and a plurality of clamping heads. The extension rod is connected to the support device 1 and is disposed outside the insulating hopper. The extension rod extends along the length of the insulating hopper, and the clamping heads are detachably connected to the extension rod. Multiple flexible cables 2 are clamped onto the support device 1 using a cable clamping mechanism, including the following steps: Fix multiple flexible cables 2 one by one to the clamping head; The clamping head clamps the middle of the flexible cable 2; Allow the cable head to hang down naturally, ensuring it is below the lowest point of the insulation hopper.

[0037] In this technical solution, the clamping mechanism is mounted on the support device 1. Without damaging the original structure of the insulating bucket, a general-purpose insulating bucket truck is quickly converted into a dedicated aerial platform for cable lifting and support. This allows most of the cable's self-weight and external load to be transferred to the bucket truck through the limit box and the insulating bucket, eliminating the need for the overhead conductor 4 to bear the entire cable weight. This avoids accidents that might occur due to defects in the conductor 4's material, diameter, or unknown defects, and eliminates the long-term risk of damage to the insulator binding wire. The extension rod extends the cable fixing point from inside the insulating bucket to an open space outside, providing the cable with... The natural and unobstructed suspension path reduces friction between the cable and the bucket arm and insulated bucket. By allowing the cable head to hang naturally and be below the lowest point of the insulated bucket, it ensures that the cable head will not collide with the insulated bucket when clamped by the insulated rod 3 and under force. Operators can easily hook the cable head by extending the insulated rod 3 downwards and forwards from inside the insulated bucket. The operation direction is ergonomic and the line of sight is unobstructed. At the same time, the state of the cable with the middle section clamped and the head hanging freely makes the cable's posture in the air stable and controllable, making it easier to clamp the insulated rod 3 and perform subsequent alignment operations.

[0038] In one feasible implementation, an insulating rod 3 is used to attach the flexible cable 2 to the corresponding overhead live conductor 4.

[0039] In this technical solution, from clamping and lifting the cable to the final splicing and tightening, the operator interacts with all live parts and non-safety distance areas through the insulating rod 3 throughout the entire process. There is no need for any part of the human body to directly contact or get too close to the high-voltage live conductor 4. The reliability of the main insulation is based on the proven solid insulation material, rather than on personal protective equipment or the estimation of air gaps, so as to realize indirect bypass operation. The operator stays away from the live parts and does not need to directly contact the live parts, thus achieving a dual improvement in work efficiency and work safety.

[0040] Furthermore, after the flexible cable 2 is attached to the corresponding overhead live conductor 4, the second insulated bucket truck 6 is operated to control the height of the insulated bucket 8 of the second insulated bucket truck. The operator then removes the attached cable from the support device 1 to complete one attachment operation.

[0041] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
