Abstract

The invention discloses a quick cutter replacing device based on a double-cam structure, and relates to the technical field of shield construction. The quick cutter replacing device comprises a cutter holder, a vertically-through cutter bin is arranged in the middle of the cutter holder, and rotatable inner rotating blocks are arranged in the middles of the front side and the rear side of the cutter bin; the inner rotating blocks are circular, clamping grooves are formed in the inner rotating blocks, and sliding grooves are arranged at the upper portions of the inner rotating blocks; the width sizes of the clamping grooves are equal to that of the sliding grooves, a pressing block is arranged below the inner rotating blocks and is fixedly connected with a cutter holder fixing bolt, and fixing holes are formed in the positions, corresponding to the fixing bolt, of the pressing block and the cutter holder; a hobbing cutter is arranged in the middle of the cutter bin, and cutter shafts at the front end and the rear end of the hobbing cutter are clamped in the clamping grooves. The quick cutter replacing device has the beneficial effects that the device is simple in structure and is convenient to operate, the disassembly and assembly procedures are reduced, and the operation efficiency is improved; the overall structure of the shield cutter holder is simplified, the cutter is convenient to disassemble and assemble, and the efficient cutter changing operation is achieved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a quick tool changing device based on a double-cam structure. Background technique [0002] With the vigorous development of my country's infrastructure industry, shield tunneling is widely used in highway, water conservancy, subway, railway and other engineering fields. It is estimated that by 2022, the total length of my country's subway, highway, railway and other tunnels will exceed 10,000 kilometers, of which medium-length and special-long The tunnel accounts for about 2 / 3. As the core component of shield excavation, the tool plays a pivotal role in the tunnel excavation process. During the shield construction process, the tool consumption is large and the replacement is frequent. The time of tool detection and tool change operations takes up More than 10% of the tunnel construction period, the existing tool change work mainly relies on manual work, there are many sca...
