Description

Technical Field

[0001] The invention relates to the technical field of circuit breaker transportation, and in particular to a straddle-type heavy-duty GIS installation platform. Background Art

[0002] Since medium and heavy HGIS (Hybrid Gas Insulated Switchgear, new high-voltage switchgear) is large in size and heavy in weight, it cannot be lifted and transported by small or light lifting equipment, and must be lifted by a large crane. According to the equipment forms available for reference at home and abroad, when the crane is in place, the distance between the top of the boom and the live body is much smaller than the safe and controllable distance, which poses a safety hazard. Therefore, when the crane is in place, the installation station needs to be powered off to carry out the work in place, but the power outage will cause a large-scale power outage, which will affect the residents who use electricity.

[0003] In the prior art, a straddle-type heavy-duty GIS installation platform of heavy-duty GIS (Gas Insulated Switchgear) can be used to transport HGIS to the installation location. However, the conventional straddle-type heavy-duty GIS installation platform has only two degrees of freedom in two directions, and the telescopic range and degree are small. A large number of straddle-type heavy-duty GIS installation platforms are required to transport large equipment, which is costly and difficult to control. In addition, the existing straddle-type heavy-duty GIS installation platform is only suitable for good road environments. If the transportation road is uneven, bumps are likely to occur, causing the equipment to bump or lose balance and fall, posing a safety hazard. Summary of the invention
