Normal-pressure tool-changing and pressure-detecting mounting bracket for shield tunneling machine

Abstract

The invention relates to the field of normal-pressure tool changing of slurry shield tunneling machines, in particular to a normal-pressure tool-changing and pressure-detecting mounting bracket for ashield tunneling machine. The bracket comprises a machine body, rear pin shafts, a front pin shaft, and a bearing; the bottom end of the machine body is fixedly connected with a base; two groups of rear support lugs are symmetrically arranged at the front and rear sides of the base; the rear support lugs are hinged to the fixing ends of an oil cylinder through the rear pin shafts; the telescopic end of the oil cylinder is hinged to a front supporting lug through the front pin shaft; the front pin shaft is in pin connection with a cotter pin; the top end of the front supporting lug is fixedly connected with a testing table; a rotating block is fixedly installed in the middle of the bottom end of the testing table; the rotating block is composed of a rotating block base body, a rotating block plane, a rotating block cylindrical face and a rotating block side face; and the rotating block cylindrical face is fixedly connected with the outer side of the rotating block base body. According to the normal-pressure tool-changing and pressure-detecting mounting bracket for the shield tunneling machine, pressure detecting can be conveniently conducted on tool changing of the shield tunnelingmachine, and manual mounting operation on a pressure detecting component is facilitated.

Description

Technical field [0001] The present invention relates to the field of mud water shield regular pressure tool, and more particularly to a shield machine for a normal pressure shifting pressure mounting bracket. Background technique [0002] The shield machine is rotated by a cutter disk and mixing the soil and mixed with water to form a slurry. Different geological soils need to select different cutter cutters to minat, and the tools on the cutter are also replaced by the work wear damage to replace new tools. Since the shield machine excavation soil causes the tunnel to produce gas pressure, it is necessary to install the inner tool of the inside the shield and the insulation of the gate assembly to ensure that the cutter is in normal pressure. status. [0003] The shield machine in the prior art is large, and there are many types of normal pressure tools, and the specification is very different and the installation method is not convenient to manually install operation. [0004] ...
