Description

A jack-type rotating lifting insulation platform

Technical Field

The invention relates to the field of power transmission line maintenance, and in particular to a jack-holding-bar type rotating lifting insulating platform.

Background Art

Live working technology refers to a method of maintenance and testing of high-voltage electrical equipment without power outage. This method of operation is an effective measure to avoid power outages for maintenance and ensure normal power supply. With the rapid development of my country's power industry and the continuous upgrading of power equipment, live working technology has become an indispensable technical means for the maintenance and operation of power systems. The content of live working can be divided into live testing, live inspection and live maintenance. The main projects are: live replacement of line tower insulators, cleaning and replacement of insulators, water washing insulators, crimping and repairing conductors and overhead ground wires, detecting bad insulators, testing and replacing disconnectors and lightning arresters, etc. In this process, in order to ensure the safety of operators, a series of insulation measures must be taken. However, traditional insulation measures often have many limitations, such as cumbersome operation and low safety. In order to solve some of the above problems, improve the safety and efficiency of operations, and provide a stable working platform, power engineers and technicians began to study and develop insulation platform auxiliary operation technology.

Most of the current insulation platforms use a gear clamp to lock the poles, and several insulating rubber heads are fixed on top of the clamps. The vertical friction between the rubber heads squeezes the poles to fix the platform in the air. However, this traditional pole locking method greatly limits the structural innovation of the insulation platform, making the structural designs of most subsequent insulation platforms very similar. At the same time, the friction provided by the traditional pole locking method is limited, which cannot meet the requirements of subsequent platforms to increase the overall weight in order to meet the multi-functional design.
