Novel large-diameter sinking headframe for ultradeep vertical shaft

Abstract

The invention discloses a novel large-diameter sinking headframe for an ultradeep vertical shaft, which consists of headframe legs, side nodes, a support rod, a W-shaped support, a Chinese character like ''mu'' shaped head sheave platform, a Chinese character like ''ge'' shaped support, a head sheave, a head sheave room, a Chinese character like ''da'' shaped support, a work ladder, and a large middle node. The upper part of the W-shaped support is connected with the Chinese character like ''mu'' shaped head sheave platform through the large middle node. The lower part of the W-shaped support is connected with the lower part of the Chinese character like ''da'' shaped support and the support rod through the large middle node. The bottom end of the Chinese character like ''da'' shaped support is connected with the headframe legs. The upper part of the Chinese character like ''mu'' shaped head sheave platform is connected with the head sheave platform through the Chinese character like ''ge'' shaped support. The head sheave room is arranged above the head sheave. The lower part of the Chinese character like ''da'' shaped support is connected with side supports through the side nodes. The work ladder extends from the bottom of the Chinese character like ''da'' shaped support to the head sheave room. The sinking headframe is suitable for construction of large shafts with a net diameter of 10-12m and a depth of 1600m above.

Description

Technical field: [0001] The invention relates to a novel large-diameter ultra-deep vertical shaft sinking derrick. Background technique: [0002] Shaft sinking derrick is a special steel structure used for lifting and suspending construction equipment during shaft shaft construction. According to the relationship between shaft construction and mine production, when constructing shaft shafts at home and abroad, special sinking derricks can be used, and production derricks can also be used. Using special sinking derricks for shaft shaft construction is one of the main methods of shaft construction at present. . [0003] my country's coal production and construction have developed rapidly in recent years. In the near future and for a period of time in the future, coal will still be the main energy source in my country. With the development and construction of resources in the western region, a new batch of super large shafts has begun to be constructed. In addition, the depth...

Problems solved by technology

[0004] The special steel derrick for shaft sinking was basically standardized in the early 1960s. In view of the scale and level of mine construction at that time, and the rapid development of mechanization for sinking in the late 1970s, especially the emergence of umbrella drills, the new type of sinking derrick only It can be used for wellbore construction with a maximum diameter of 8m and a maximum depth of 1000m. For larger-scale wellbores in recent years, the adaptability of existing sinking derricks has been restricted, and the development of large-diameter ultra-deep shaft shaft construction technology needs to be further expanded. , so it is necessary to develop and design a large-diameter ultra-deep shaft sinking derrick
