Intelligent assisting platform for dismounting and mounting of GIS (Gas Insulated Substation)

Abstract

The invention discloses an intelligent assisting platform for dismounting and mounting of a GIS (Gas Insulated Substation). The intelligent assisting platform comprises a base, a hoisting mechanism, a sliding mechanism, an oil tank, a forward pushing mechanism and a front gear mechanism, wherein the sliding assembly comprises a guide rail which is mounted on the base, and two sliding tables which are movably mounted on the guide rail; a pitch-variable oil cylinder is arranged between the sliding tables; the hoisting mechanism comprises uplifting oil cylinders, hoisting arms, hoisting hooks, coiling barrels and gear motors, wherein the uplifting oil cylinders, the hoisting arms, the hoisting hooks, the coiling barrels and the gear motors are correspondingly arranged on the sliding tables; the forward pushing mechanism comprises lead screw assemblies, forward pushing oil cylinders and forward pushing clamping jaws, wherein the lead screw assemblies, the forward pushing oil cylinders and the forward pushing clamping jaws are correspondingly vertically arranged on the two sliding tables; the front gear mechanism comprises front gear oil cylinders and front gear clamping jaws; the front gear oil cylinders and the front gear clamping jaws are horizontally arranged on the uplifting oil cylinders. The intelligent assisting platform can effectively avoid natural shaking of an air chamber caused by hoisting a GIS air chamber through a soft sling and various resulting potential risks, so that GIS devices can be accurately, quickly and stably hoisted and adjusted, and as a result, the safety and quality can be ensured, and the labor intensity can be also reduced.

Description

technical field [0001] The invention relates to an intelligent auxiliary platform for GIS disassembly and assembly, and belongs to the technical field of GIS disassembly and assembly in electric power systems. Background technique [0002] In recent years, GIS substations have been widely popularized because of their advantages of good reliability, maintenance-free and small footprint. At the same time, the maintenance workload of GIS equipment will also increase. [0003] In view of the increase in the workload of disassembly and assembly of GIS and the high requirements of the operation, there are mainly the following problems at present: [0004] 1. The feasibility of disassembly and assembly operation under the existing conditions is poor: most of the switch rooms of existing GIS substations are not equipped with electric cranes, and only lifting rings are pre-installed on the roof. In addition, some GIS are indoors and cannot be operated by cranes. At present, when the...

Problems solved by technology

[0004] 1. The feasibility of disassembly and assembly operation under the existing conditions is poor: most of the existing GIS substation switch rooms are not equipped with electric cranes, only the lifting rings are pre-installed on the roof, and some GIS are indoors, and crane operations cannot be used

At present, when the roof ring is in use, not only the position cannot be moved, but also its applicability is greatly reduced because it is on the roof;

[0005] 2. The safety of the existing disassembly operation method is poor: when using poles or scaffolding for lifting and disassembly operations, it is difficult to choose the support point of the pole, and the scaffolding is too thin, and it is difficult to guarantee the load bearing

The GIS air chamber is easy to shake, and the safety is not guaranteed

Moreover, these operating equipment are generally rented from outside. These temporary equipment lack normalized and professional safety tests and monitoring, and the reliability of the equipment cannot be guaranteed;

[0006] 3. The existing disassembly and assembly operation method has a negative impact on the disassembly and assembly process of GIS equipment, especially when the contact surface of the GIS air chamber is aligned, because the hoisting equipment needs to adjust the position accurately in all directions, the natural force of the sling is affected during this process. Shaking will greatly affect the reliability and accuracy of alignment

The inaccurate position of the contact surface of the GIS air chamber will lead to collision or friction damage of the flange sealing surface during disassembly, distortion or displacement of the sealing rubber ring, and uneven internal stress on the contact surface, which greatly increases the hidden dangers of quality.
