Description

Technical Field

[0001] The present application relates to the field of power tools, and in particular to a tool and method for installing and replacing an overhead line tension insulator string. Background Art

[0002] An insulator string is a combination of two or more insulators. In transmission lines, only when the insulators are combined into a string can the mechanical and electrical requirements be met. Due to different usage requirements, there are many forms of insulator strings, and their stress conditions are very different because the insulator string must be connected to the pole tower and the conductor. Insulator strings usually include different types such as straight insulator strings and tension insulator strings. Straight insulator strings are mainly used to support the conductor on the straight pole tower and play an insulating role; tension insulator strings are used in special locations such as tension pole towers to bear the conductor tension and play an insulating role.

[0003] Strain insulator strings are important components in the process of erecting transmission lines. They mainly include ceramic strain insulator strings and composite strain insulator strings. They can effectively isolate the live wires from the ground and keep the wires in their own positions. In the operation and maintenance of transmission lines, damage to insulators is inevitable due to various factors. Strain insulator strings are the most common products for erecting transmission lines today. They are used together with supporting power fittings. According to construction needs, several products are strung together to meet the tension requirements.

[0004] With the continuous development of the modern power industry and the increase in power load, a large number of overhead lines need to be built. At the same time, many old overhead line insulator strings also need to be replaced. When installing and replacing insulator strings of traditional overhead lines, pulley traction ropes are used to pull the overhead lines and then install or replace the tension insulator strings. When replacing, the pulley block needs to be installed on the angle steel crossarm. The installation and disassembly process of the pulley block and traction rope is cumbersome and laborious, and pulling the pulley block is more physically demanding. Summary of the invention

[0005] In order to save time and effort when replacing a tension insulator string, the present application provides an installation and replacement tool and an installation and replacement method for an overhead line tension insulator string.

[0006] The present application provides an overhead line tension insulator string installation and replacement tool and installation and replacement method, which adopts the following technical solutions:

[0007] An overhead line tension insulator string installation and replacement tool and installation and replacement method, comprising:

[0008] The angle steel fixing part is detachably mounted on the angle steel cross arm, and includes an angle steel fixing piece for detachably mounting the installation and replacement tool on the angle steel cross arm, and a fixing piece connector disposed on the angle steel fixing piece for mounting the angle steel fixing piece;

[0009] The outer frame comprises a fixed arm and a traction arm, wherein the fixed arm and the traction arm are alternately connected to enclose the outer frame, and the fixing member connecting member is arranged between the angle steel fixing member and the traction arm;

[0010] The traction part comprises a traction component which is installed on the outer frame and partially located inside the outer frame, and a driving component which is used to drive the traction component to operate.

[0011] By adopting the above technical solution, the angle steel fixing piece in the angle steel fixing part can be detachably installed on the angle steel cross arm, so that the tool can be quickly installed in place when in use, and can be easily disassembled when not in use, which is convenient for carrying and storage. The fixing piece connector further strengthens the connection stability between the angle steel fixing part and the outer frame, and is also convenient for disassembly and adjustment when necessary; the outer frame is formed by the fixed arm and the traction arm, providing a stable installation space and support structure for the traction part, so that the tool as a whole will not be deformed or shaken during the installation and replacement of the tension insulator string, thereby improving the safety and reliability of the work;

[0012] The fixed arm and the traction arm are used to withstand the tension and pressure during the traction process to ensure that the tool will not be damaged or malfunction during use. The traction assembly and the drive assembly cooperate with each other to provide strong traction, making the installation and replacement of the tension insulator string more efficient. The use of this tool can greatly reduce manual labor intensity, improve work efficiency, and save time and labor costs.

[0013] Preferably, the fixed arms and the pulling arms are alternately arranged to enclose the outer frame, and every two adjacent fixed arms and pulling arms are connected end to end.

[0014] By adopting the above technical scheme, the two fixed arms and the two traction arms are arranged alternately and enclosed to form an outer frame, forming a relatively stable quadrilateral structure. When performing traction operations, it can better withstand forces from all directions, reduce deformation and shaking of the outer frame, and improve the overall stability of the tool. The adjacent fixed arms and traction arms are connected end to end in sequence, so that the force transmission is more uniform and continuous, and the rigidity of the outer frame is enhanced. The tension and torque generated during traction are effectively resisted, ensuring that the tool will not become loose or damaged during operation. The design of the two fixed arms and the two traction arms can be adjusted and optimized according to different work requirements. For example, the length, angle or connection method of the fixed arms and the traction arms can be changed to adapt to angle steel crossarms and tension insulator strings of different specifications, thereby improving the adaptability and versatility of the tool.

[0015] Preferably, the traction assembly includes a plurality of lead screws rotatably connected to the traction arms, and a traction block inserted through the lead screws, and after the driving assembly controls the lead screws to rotate, the traction block moves along the length direction of the lead screws.

The position of the traction block can be accurately adjusted by rotating the lead screw, thereby accurately controlling the moving distance of the tension insulator string, which is very important for position adjustment when installing and replacing the insulator string. It can ensure that the insulator string is installed in the correct position. The traction block is inserted into the lead screw to make the traction process smoother, avoid sudden impact and vibration, and reduce the risk of damage to the insulator string and other equipment. Compared with a single traction method, multiple lead screws can share the traction force and reduce the situation of excessive local force, thereby reducing the risk of damage to the insulator string and tools. If greater traction force is required, the number of lead screws can be increased or a lead screw with a larger diameter can be selected to meet the installation and replacement needs of tension insulator strings of different types and specifications.

When the wire passes through the first receiving port and is clamped into the wire clamp, the wire is firmly fixed on the traction block, avoiding the wire from sliding or falling off during the traction process, ensuring the safety and reliability of the operation. After the wire is stably fixed on the traction block, the traction component can avoid the loss of traction force caused by the loosening of the wire when moving the traction block, making the traction process more efficient and quick. The first receiving port on the traction block and the wire clamp on the wire chuck make the installation and removal of the wire very convenient. The operator can quickly put in or take out the wire, which improves the work efficiency. The size and shape of the wire clamp can be designed according to different wire specifications, so that the tool can adapt to various wires of different diameters and types, improve the versatility and applicability, and reduce the need to replace the tool due to different wire specifications.

In actual overhead line maintenance and installation work, conductors of various diameters may be encountered. This design enables the tool to flexibly respond to different conductor size requirements and improves the versatility of the tool. When using the tool, the operator can quickly select the appropriate conductor clamp according to the actual conductor size to improve work efficiency. The conductor clamp of the appropriate size can better fix the conductor to ensure that the conductor will not loosen or shake during the traction process. Stable fixation can reduce collisions, wear and other problems that may be caused by conductor shaking, extend the service life of the conductor, and also improve work safety.

Hardware and conductors of different types and specifications can be placed in corresponding accommodating ports according to their sizes and shapes, adapting to a variety of different combinations of hardware and conductors, improving versatility and adaptability. The design of the accommodating ports makes the hardware and conductors more orderly during the traction process, and operators can operate in a certain order to avoid confusion and errors, which is conducive to optimizing the work process and improving the standardization and standardization of operations.

[0024] Preferably, a hardware fixing lock buckle is provided at the opening of the second receiving opening, and a wire fixing lock buckle is provided at the opening of the third receiving opening, and both the hardware fixing lock buckle and the wire fixing lock buckle can be switched to a closed state and an open state;

[0025] When the hardware fixing lock is in a closed state, the hardware fixing lock and the second accommodating opening are combined to form a second accommodating space. When the wire fixing lock is in a closed state, the wire fixing lock and the third accommodating opening are combined to form a third accommodating space.

When the lock buckle is closed, it forms a closed accommodation space with the corresponding accommodation opening, which can tightly fix the hardware and the wire to prevent them from accidentally falling out during traction. This stable fixation can withstand greater traction and external force impact, ensure that the hardware and the wire remain stable in a complex overhead line environment, and improve the safety and reliability of the operation. The design of the lock buckle can be adjusted according to the actual size of the hardware and the wire, so that it can adapt to hardware and wires of different specifications.

According to different work requirements, the controller can adjust the output power, speed, direction and other parameters of the drive component to achieve fine control of the traction process, ensure the installation and replacement of the tension insulator string is accurate, and improve the quality of work. The power supply is electrically connected to the controller, and the controller is connected to the drive component. This connection method can realize the safe management of the power supply.
