Technical Field
[0001] This utility model relates to the field of trolley technology, specifically a liftable mobile compressed air energy storage trolley for laying. Background Technology
[0002] A cavern is a man-made or naturally existing structure within underground rock and soil for various purposes. The design and construction of caverns require careful consideration of the strength and stability of the rock mass to ensure safety and economic efficiency. Compressed air energy storage caverns are primarily used for compressed air energy storage. Their core design concept utilizes the strength of the rock mass to form a hard shell layer, and the deformation-restrained sealing layer absorbs the air expansion pressure, ensuring the cavern's stability.
[0003] Before use, the inner wall of a compressed air energy storage silo needs to be sealed. This is usually done by laying a trolley. However, the existing trolleys generally have fixed frames, which are not very flexible. If the silo has a variable inner diameter, each section requires a trolley of a corresponding height, which increases costs. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content
