Segment assembly robot for miniature shield machine

Abstract

The invention provides a segment assembly robot for a miniature shield machine, which is applied to the shield machine industry. The robot comprises a guide wheel, a lifting guide rod, a lifting oil cylinder, a driving device, a translation oil cylinder, a horizontal guide rail, an oscillating oil cylinder and the like, wherein, the guide wheel and a thrust wheel are respectively welded on the inner wall of a shield body and also serve as a supporting track for the segment assembly robot to rotate along an X axis; the driving device is fixed on a shield body bracket, and a pinion in the driving device is meshed with a bull gear in a rotating ring; the cylinder body part of the lifting oil cylinder is connected with the lifting guide rod, the piston rod end of the lifting oil cylinder is connected with the horizontal guide rail through a mechanism, and a fixed end of the lifting guide rod is fixed on the rotating ring; a grabbing head is connected with a segment through a segment lifting pin; and four groups of fine adjustment oil cylinders are supported on four points of the segment to fix the segment. The device has unique and scientific conception and exquisite and compact structure, meets the special requirement of spatial arrangement structurally, provides sufficient installation space for related components such as a spiral conveyer and the like, and meets the precision requirements of various actions and positioning in each direction in the segment assembly process.

Description

technical field [0001] The invention relates to a segment assembling robot for a micro-shield machine, which is responsible for installing the prefabricated segment on the surface of a newly excavated tunnel to form a lining after the shield tunneling is completed. Background technique [0002] At present, in large-diameter shield tunneling machines, cantilever or single-arm segment assembly machines are generally used. The segment assembly machine moves horizontally and rotates on its arm, and the screw conveyor passes through the center of the segment assembly machine. The space structure Well laid out without interference. For the micro-shield, when the larger-diameter screw conveyor obliquely passes through the center of the segment assembly machine, the structure will be limited by space and layout, and even interfere with the screw conveyor when it rotates or moves, making it difficult to It meets the requirements for the layout of the narrow space in the micro-shield...
