Description

Technical Field

[0001] The utility model relates to the technical field of coal mine shaft opening inspection and maintenance, in particular to a fast-retractable shaft opening inspection and maintenance platform. Background Art

[0002] In the current coal mine shaft operation, the cage is a key container for lifting personnel and materials, and its safe operation is of vital importance. The lifting of the cage depends on the wire rope, so regular inspection and maintenance of the wire rope and cage facilities is a necessary measure to ensure the safe use of the cage.

[0003] At present, when the cage and the wire rope for cage lifting are inspected and repaired at the shaft mouth of a coal mine, a temporary inspection platform is mainly built by manual means using templates at the shaft mouth of the coal mine. Although the temporary inspection platform can assist workers in inspecting the cage and the wire rope for cage lifting at the shaft mouth of the coal mine, on the one hand, there is no place for centralized placement of inspection tools on the temporary platform, which leads to the need for workers to repeatedly step down from the platform to get the inspection tools during the inspection process, posing a safety hazard of workers accidentally falling off the inspection platform. At the same time, due to the temporary There is no structure on the platform built at the time to prevent maintenance tools from accidentally falling. During the maintenance process, maintenance tools are easily dropped from the edge of the maintenance platform into the coal mine shaft, which may cause damage to the equipment in the coal mine shaft. On the other hand, the temporary maintenance platform needs to be laid manually by workers, which not only has a low laying efficiency, but also makes it inconvenient to put away the maintenance platform at the later stage, which makes the workers have a higher labor intensity during the maintenance process and is not convenient for efficient maintenance of the cage at the mouth of the coal mine shaft and the wire rope used for lifting the cage.
