Description
Technical field
The utility model relates to electric power system mesohigh circuit breaker and isolating switch maintenance special equipment.
Background technology
Along with the continuous development of China's economic construction, electric power system has obtained very fast development in recent years.Compactness makes common hanging device and the equipment of ascending a height can not enter the scene very easily because transformer station designs more and more in daily maintenance; Previously used service kit can not satisfy specification requirement again in new safety requirements.In order to ensure site operation personnel's safety, can effectively reduce the power failure scope again, press for the special-purpose frame of a kind of novel maintenance and solve the problem that runs in the maintenance like this.
Summary of the invention
The purpose of this utility model is in order to solve the problem of above-mentioned existence, to provide a kind of novel high-voltage circuit-breaker and isolating switch to overhaul special-purpose frame, improving the safety of electric power enterprise operation, improve the quality of maintenance, guarantee personal safety, reduce labor intensity, increase work efficiency.
Realize that the technical scheme that the utility model purpose is taked is: this device is made up of the two large divisions: lifting part and insulation scaffold part, wherein lifting partly comprises suspension hook, lifting base, arm, lifting reinforcement support bar, arm is installed on the lifting body frame, and lifting is strengthened support bar and withstood on lifting body frame bottom; The insulation scaffold partly comprises platform framework, supports stand, prevents turning over supporting leg, ladder, guardrail, operating platform that prevent turning over the outward-dipping installation of supporting leg, operating platform is installed on the platform framework up and down, is provided with guardrail around last operating platform; Two joint ladders connect operating platform and last operating platform down respectively.
Arm is connected on the lifting body frame through the lifting base, and can horizontally rotate on the lifting body frame.
Be provided with a transmission mechanism in the lifting base, the crank of outside connects transmission mechanism, and transmission mechanism can drive the angle that stay cord is regulated the arm vertical direction.
In order to make fitting operation efficient and convenient, the connection of all rod members all adopts the grafting bolt to connect.
On the leg that supports the stand lower end, be provided with tunable arrangement, can regulate the length of leg within the specific limits.
Good effect of the present utility model is: efficiently solve the existing technical problem that exists, can lift maintenance to 110kV and following switch, 220kV and following disconnecting link; Arm can horizontally rotate 120 °, rotates 30 ° up and down, and hoisting weight is less than 500 kilograms object; This repairing frame is reasonable in design, in light weight, fitting operation is simple, esy to use, safe and reliable; The use of this repairing frame can alleviate the maintainer labour intensity, strengthen coefficient of safety, increase work efficiency, 3～4 people can finish dismounting in 15 minutes, 1～2 people can lift operation.
