Description

Technical Field

[0001] This application relates to the field of cranes, and more specifically to a device for moving mobile opening and closing equipment in confined spaces. Background Technology

[0002] Hydropower stations are equipped with tracks for moving mobile gate hoists. However, the installation of these mobile gate hoists is often carried out on one side of the dam. When there are facilities such as engine rooms on one side of the dam, the installation space is limited, making it impossible to use large hoisting equipment. In such cases, the installation track for the gate hoist may be misaligned by several meters with the working track on the dam surface. Therefore, after the mobile gate hoist is installed on the installation track, moving it from the installation track to the working track is a significant challenge. Thus, a mobile gate hoist designed for confined spaces is needed, allowing for the movement of the equipment between different tracks within narrow spaces.

[0003] For example, a Chinese patent, publication number CN221168335U, publication date June 18, 2024, entitled "A Roof-Mounted Thrust Reverse Exhaust Structure," is a utility model patent. Its technical solution is as follows: This utility model belongs to the field of aero-engine testing technology, specifically involving a roof-mounted thrust reverse exhaust structure. The exhaust mechanism includes a roof steel frame, a hanging column, a first track, a rotary drive assembly, a transport trolley, a volute support, a thrust reverse exhaust volute, an engine, a volute locking assembly, a second track, and a rotary track. The two tracks are vertically divided and fixed to the roof steel frame by the hanging column. The first track is perpendicular to the engine intake direction. The rotary drive assembly drives the transport trolley to rotate 90 degrees in place. The transport trolley can slide on the first track, the second track, and the rotary track. A volute support is installed on the transport trolley for installing the thrust reverse exhaust volute. After the transport trolley rotates 90 degrees in place, the engine is installed and fixed.

[0004] The aforementioned patent enables the transport trolley to change direction by 90 degrees on the track during reverse thrust testing, achieving precise track positioning. However, the rotating track of the aforementioned patent requires a suspended rotating component to rotate the track. This track is not suitable for the movement of mobile gate opening and closing equipment in narrow spaces in hydropower stations, thus failing to achieve the technical effect of changing the track of the mobile gate opening and closing equipment from the installation track to the working track.
