Description

Technical Field

[0001] This invention relates to the field of post insulator replacement equipment, specifically a mainline locking tool and its working method based on insulator replacement. Background Technology

[0002] Post insulators are special insulating components that play a crucial role in overhead transmission lines. In the past, post insulators were primarily used on utility poles. Gradually, they evolved into numerous suspended insulators hanging at one end of high-voltage power line towers to increase creepage distance. These are typically made of silicone or ceramic and are called insulators. Insulators in overhead transmission lines perform two fundamental functions: supporting the conductors and preventing current from returning to ground. Both functions must be guaranteed. Insulators should not fail due to flashover breakdown caused by changes in environmental and electrical load conditions; otherwise, the insulators will become ineffective, compromising the service life and operational lifespan of the entire line.

[0003] When a post insulator fails, it needs to be replaced with machinery and equipment. Ensuring the secure locking of the main line at the top of the insulator during replacement is a technical challenge. Summary of the Invention

[0004] To address the problems of existing technologies, this invention provides a main line locking tool and its working method based on insulator replacement. When replacing post insulators, the main line is clamped by locking consumables, and then connected to the replacement equipment through a docking drive assembly. The structure is simple and easy to use.

[0005] This invention provides a mainline locking tool based on replacing insulators, including a mating drive assembly and locking consumables that are connected together. The locking consumables are fixedly connected to the post insulator, and the mating drive assembly is connected to an external device.

[0006] The locking consumable includes an insulating left clamp and an insulating right clamp connected by a screw structure. An insulating rotating pressure block is connected to the insulating left clamp by a rotating pin. The inner wall structure of the insulating rotating pressure block and the insulating right clamp matches the outer edge of the post insulator. When the insulating rotating pressure block rotates toward the insulating right clamp, it presses the main wire into the groove of the post insulator. A bolt is connected to the left side of the insulating left clamp.

[0007] The docking drive assembly includes a drive shaft, a universal joint assembly, a transmission shaft, and a universal sleeve connected in sequence. The bolts in the locking consumables are inserted into the universal sleeve and connected to the universal joint assembly. The outer edge of the drive shaft is fitted with a tool disk and a guide positioning disk connected by an upper locking rod. The drive shaft is connected to the docking equipment through the tool disk and the guide positioning disk. The outer edge of the universal sleeve is fitted with a floating device, a side end cover, and a guide sleeve in sequence. The floating device and the guide positioning disk are connected by a transition base.

[0008] In a further improvement, the floating device includes a floating device base, a floating platform, a floating device middle frame, and a floating device end cap, which are sequentially fitted onto the outer edge of the universal sleeve. The floating device base is connected to the transition base, and the floating device end cap is connected to the side end cap.

[0009] In a further improvement, a lubrication plate is provided between the base of the floating device and the floating platform, a lubrication plate is provided between the floating platform and the middle frame of the floating device, and a tension spring is provided between the middle frame of the floating device and the end cap of the floating device.

[0010] In a further improvement, the universal joint assembly includes universal joint one and universal joint two, which are installed inside the transition base and connected to each other. Universal joint one is connected to the drive shaft, and universal joint two is connected to the transmission shaft.

[0011] In a further improvement, a transmission pin is provided on the drive shaft, and an inclined block is provided inside the tool disk.

[0012] In a further improvement, the bolt is connected by a ball head nut and an insulating left clamp. A calibration plate is provided on the side of the insulating left clamp near the bolt. The docking equipment locates the bolt position by scanning the reflection of the calibration plate with a laser.

[0013] As a further improvement, the insulating rotating pressure block and the inner wall of the insulating right clamp are provided with anti-slip pads.

[0014] This invention also provides a working method for a mainline locking tool based on replacing insulators, comprising the following steps:

[0015] 1) The locking consumables are installed manually on the top of each post insulator, and the rotating insulating pressure block presses the main line into the groove at the top of the post insulator;

[0016] 2) When replacing the post insulator, open the top insulating rotating pressure block of the old post insulator, and use the jacking device to lift the main line to separate the main line from the old post insulator;

[0017] 3) Replace the drive shaft connection at one end of the equipment and the docking drive assembly, and drive the universal sleeve at the other end of the docking drive assembly toward the bolt in the locking consumable, so that the bolt is inserted into the universal sleeve, and move the old post insulator to the equipment replacement location.

[0018] 4) Separate the drive assembly from the locking consumables on the old post insulator and connect it to the locking consumables on the new post insulator, then move the new post insulator back to its original position for installation.

[0019] 5) The lifting device lowers the main line, and the rotating insulating pressure block rotates to press the main line into the groove at the top of the post insulator, completing the installation.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. When replacing the post insulator, the main line is clamped by locking consumables, and then connected to the replacement equipment by docking drive components. The structure is simple and easy to use.

[0022] 2. The design of the floating device makes it easier to connect the locking consumables and the docking drive components. Attached Figure Description
