A variable section vertical shaft excavation device

Abstract

The present invention proposes a shaft excavation device with variable section, which includes a shield body and a muck conveying system, a cutter head device is arranged under the shield body, the cutter head device is connected with a swing device, and the swing device is connected with a cutter head translation device , the cutter head translation device is slidably arranged on the circular rotation device, and the circular rotation device is arranged on the inner side of the shield body. The present invention swings the cutter head up and down under the action of the oscillating device, uses the cutter head translation device to drive the cutter head to move, and cooperates with the circular gyration device to drive the cutter head device to realize a large revolution, thereby realizing the high-efficiency excavation of different sections of the cutter head, realizing It improves the full mechanization and automation of shaft construction, improves the excavation efficiency, facilitates the disassembly and assembly of equipment, reduces the number of operators, and reduces the labor intensity of personnel; It is a prefabricated structure, and the combination of equipment in the shield can be changed according to different sections, which can be applied to shaft projects with different sections.

Description

technical field [0001] The invention relates to the technical field of shaft excavation equipment, in particular to a variable-section shaft excavation device. Background technique [0002] At present, there are more and more shaft projects at home and abroad and the cross-sections are of different sizes. However, the mainstream construction method for shafts still stays on manual and semi-mechanized excavation methods. There are many, there are certain safety hazards, and the construction process is complicated, the construction efficiency is obviously low, and the shaft completion cycle is long. The shaft drilling rig used for shaft construction is mainly used in shaft projects with small cross-sections. The patent application number is "CN2016211567123" , The patent name is "a small cross-section shaft rapid excavation device", which discloses a device with adjustable drilling angle suitable for small cross-sections. By adjusting the angle of the drilling machine, the sel...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the technical problems that the equipment in the current shaft construction is still manual and semi-mechanized, the applicability of the equipment is relatively limited and the capacity of the equipment itself is limited, there are obvious disadvantages and deficiencies in the construction of large-section shafts, and even the technical problems that cannot meet the requirements of normal use, the present invention proposes A vertical shaft excavation device with variable section, which can be widely used in the construction of large shaft projects such as mines, tunnels, hydropower, municipal, national defense, etc.
