Semi-automatic power equipment descender

Abstract

The invention discloses a semi-automatic electrical equipment descent control device. The semi-automatic electrical equipment descent control device comprises a base, and further comprises a pulley which is in winding transmission fit with the upper section of a lifting rope, wherein a locking device for locking the base to a lower beam of a power tower is arranged on the base; a relatively thickcircular tube is transversely, perpendicularly and fixedly arranged on the base; the lifting rope is wound on the circular tube; a locking device used for locking the pulley to an upper beam of the power tower is also fixedly arranged on the upper end of the pulley; and an external locking device and an internal locking device are further mounted on the base. The semi-automatic electrical equipment descent control device is light in weight, is convenient to carry, and can be quickly mounted to the lower part of the power tower or a power transmission tower, so that one person can stand on ground to easily complete work of dropping a heavy insulator string, and dropping speed is stable and controllable; and when an emergency appears, the lifting rope of the insulator string below can be locked, so that the insulator string does not drop onto the ground to cause an accident, and therefore, safety of staff and equipment is very high.

Description

technical field [0001] The invention relates to a semi-automatic power equipment descender. 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 rep...

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
