A segment assembly device for a small tunnel boring machine

Abstract

The invention discloses a duct piece assembly piece for a small tunnel boring machine. The duct piece assembly piece comprises a drive device, a fixed frame, a revolving support bearing, a revolving frame, a lifting device, a slide frame, a slide oil cylinder and anti-shaking oil cylinder, wherein one end of the fixed frame is fixed on a shielding body, and the other end thereof is connected and fixed with the outer ring of the revolving supporting bearing; a pinion of the power output end of the drive device is engaged with the inner gear ring of the revolving support bearing; the revolving frame is sleeved on the inner gear ring of the revolving support bearing; and the lifting device is fixed on the lower end of the revolving frame. The duct piece assembly device adopting the technical solution has a simple and compact structure and light weight. When the duct piece assembly is satisfied, the spatial arrangement requirements are ensured, and sufficient space is provided for installing parts such as a discharging part and the like. The duct piece assembly device is very suitable for use in a construction process of the small tunnel boring machine.

Description

technical field [0001] The invention relates to equipment for tunnel excavation construction, in particular to a segment assembling device for a small tunnel boring machine. Background technique [0002] With the development of urbanization, more and more small-diameter roadheaders are used for the development of common trenches for urban pipelines. This kind of small roadheader can complete segment assembly during construction, and is highly efficient and safe to use, so it is widely used. However, due to structural limitations, the segment assembly space is narrow. The traditional segment assembly device uses an oil cylinder guide rod device to move the segment radially, which takes up a lot of space and is inconvenient to rotate with the segment. In addition, the center of rotation is narrow and narrow, which makes it difficult to install the dregs removal device (such as screw conveyor, belt conveyor, etc.) in the center and pass through the staff. The existing segmen...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the small-diameter roadheader has a narrow space when assembling the segment lining, and the existing segment assembling device has a complex structure and takes up a large space, resulting in a crowded center and difficulty for personnel to pass through.
