Description

GIS disassembly and assembly intelligent auxiliary platform spreader

technical field

The utility model relates to a sling, in particular to a sling for an intelligent auxiliary platform for GIS assembly and disassembly.

Background technique

GIS (Gas Insulated Substation) is the abbreviation of the English name of gas insulated substation. In a gas-insulated substation, most of the electrical equipment is directly or indirectly sealed in a pipe tree composed of metal pipes and casings, and no switches, lines and terminals can be seen from the outside. The interior of the pipeline tree uses SF6 gas as the insulating medium, and all high-voltage electrical components are sealed in grounded metal cylinders. It is a high-voltage power distribution device composed of seven kinds of high-voltage electrical appliances, including circuit breaker, bus bar, disconnector, voltage transformer, current transformer, lightning arrester and bushing.

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.

In view of the increase in the workload of disassembly and assembly of GIS and the situation of high operation requirements. Currently there are three main problems:

The feasibility of disassembly and assembly operation under the existing conditions is very poor. Most of the switch rooms of the existing GIS substations are not equipped with 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 suspension ring of the roof is in use, not only the position cannot be moved, but also its applicability is greatly reduced because it is on the roof.

The safety of the existing disassembly operation mode is poor. When using poles or scaffolds for lifting and disassembling operations, it is difficult to choose the support point of the poles, and the scaffolding is too thin to guarantee the load bearing. The GIS air chamber is easy to shake, and its safety cannot be 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.

The existing disassembly and assembly operation methods have a negative impact on the disassembly and assembly process of GIS equipment, especially the natural shaking of the sling, and the mechanical lifting of the sling and the boom. In the existing disassembly and assembly operations, the inaccurate alignment of the GIS air chamber will lead to increased uncertainty during disassembly and assembly, greatly increasing man-hours, uneven force on the sealing surface does not meet the requirements, and distortion of the sealing rubber ring. GIS gas chamber sealing is potentially affected by inaccurate positioning of the contact surfaces or uneven internal stress on the contact surfaces.

At present, there is a patent CN105347206A for a platform for GIS disassembly and assembly in the prior art, which discloses an intelligent auxiliary platform for GIS disassembly and assembly, including a base, and a lifting mechanism, a sliding mechanism, a fuel tank, a forward pushing mechanism, and a front gear mechanism arranged on the base. , wherein, the sliding mechanism includes a guide rail fixedly installed on the upper surface of the base, and two slide tables movably installed on the guide rail, and a pitch-variable oil cylinder for adjusting the distance between the two slide tables is arranged between the slide tables; The lifting mechanism includes a lifting cylinder respectively arranged on the sliding platform, a boom installed on the hydraulic rod of the lifting cylinder, a hook installed at the front end of the boom, and a reel and a reduction motor installed on the base. The hook is connected to the reel through a rope, and the reel is driven by a geared motor; the forward push mechanism includes a screw assembly vertically arranged on two sliding tables, and the top of the lead screw assembly is provided with a horizontal forward push oil cylinder. The top of the hydraulic rod of the push cylinder is provided with a forward claw; the front gear mechanism includes a front gear cylinder horizontally arranged on the hydraulic rod of the lifting cylinder, and the top of the hydraulic rod of the front gear cylinder is provided with a front gear claw; Both the forward push claw and the front gear claw are provided with pressure sensors, and the oil tanks provide oil sources for each oil cylinder respectively.

Through practical operation, it is found that the stability of the spreader of the intelligent auxiliary platform for GIS disassembly and assembly in the prior art still needs to be improved.

Utility model content

Aiming at the problems in the prior art, the utility model provides a GIS disassembly intelligent auxiliary platform spreader with better stability and simpler operation.

In order to achieve the above technical objectives, the technical solution of the utility model is: a GIS disassembly intelligent auxiliary platform spreader, including a base, a lifting cylinder, a boom, a fixed cylinder, a claw assembly and a hoisting device. The cylinder body of the lifting cylinder is installed on the base, the telescoping end of the lifting cylinder is connected with one end of the boom, the other end of the boom is provided with a pulley, and the boom is also provided with a fixed cylinder. The telescopic end of the fixed oil cylinder is provided with a gripper assembly, and the gripper assembly is rotatably matched with the telescopic end of the fixed oil cylinder. On the base, the cord on the cord reel passes through pulleys.

Preferably, the lifting oil cylinder is rotatably matched with the base.
