Portable tools for power inspection

Abstract

The invention discloses a portable tool for electric power patrol inspection. The portable tool for electric power patrol inspection comprises a base. The base is provided with a locking device whichlocks the base to a cross beam on the lower portion of a power tower. A thick round pipe is perpendicularly, fixedly and transversely arranged on the base. A lifting rope is wound around the round pipe. The portable tool for electric power patrol inspection further comprises a pulley, and an upper section of the lifting rope is wound around the pulley and matched with the pulley in a transmissionmanner. The upper end of the pulley is fixedly provided with a locking device locking the pulley to a cross beam on the upper portion of the power tower. The base is further provided with an outer locking device and an inner locking device. The portable tool for electric power patrol inspection is light in weight, convenient to carry and capable of being rapidly installed on the lower portion of the power tower or a power transmission tower. One person can easily complete the work, on the ground, of lowering a heavy insulator string, the lowering speed is stable and controllable, under emergency conditions, the lifting rope of the lowered insulator string can be locked, it is avoided that the insulator string falls to the ground and causes accidents, and the safety of personnel and equipment are both high.

Description

technical field [0001] The invention relates to a portable tool for power inspection. Background technique [0002] Insulator strings are commonly used power devices in power supply lines. Structurally, they are mainly composed of two or more insulator elements, which are used to flexibly suspend wire components. Used to suspend and insulate conductors from towers and earth. Therefore, wherever there are power transmission lines and transmission towers, insulator strings must be used to connect transmission lines and transmission towers, which is widely used and the number of applications is also very large. [0003] In order to ensure the reliable operation of the insulator strings, not only regular inspections are required, but also regular maintenance of the insulator strings is required, and insulator sheets that have problems need to be replaced. Since insulator strings often contain 20-30 pieces of insulation, they are very heavy. Since there is no special replaceme...

AI Technical Summary

Problems solved by technology

Since there is no special replacement tool, at least several people are required to complete the replacement operation, and it is on a high-altitude transmission tower, so the operation is very difficult

Especially when lowering the insulator strings from a high altitude to the ground, once the hand slips or loosens due to fatigue, the insulator strings will fall directly to the ground, not only easily smashing the ground appendages, but also the insulator strings will suffer irreparable damage

What's more serious is that if there are problems such as fatigue in the high-altitude operators, it will be more dangerous
