Novel rotary excavating tooth coal cutting tooth of shield tunneling machine

Abstract

The invention discloses a novel rotary excavating tooth coal cutting tooth of a shield tunneling machine, and relates to the technical field of shield tunneling machine accessories. The novel rotary excavating tooth coal cutting tooth comprises a mounting seat, a rotary excavating tooth body and an alloy tooth head, wherein the alloy tooth head is fixedly connected to the bottom of the rotary excavating tooth body, a transmission slot is formed in the bottom of the mounting seat, a square transmission rod is fixedly connected to the top of the rotary excavating tooth body, the square transmission rod is matched with the transmission slot, a main damping spring rod is fixedly connected to the inner wall of the top of the square transmission rod, and a damping plate is fixedly connected to the bottom end of the main damping spring rod. According to the novel rotary excavating tooth coal cutting tooth, during installation, only the square transmission rod needs to be inserted into the transmission slot, four arc-shaped installation plates are pushed so as to clamp the rotary excavating tooth body, a splicing sleeve slides downwards so as to sleeve the arc-shaped installation plates, the splicing sleeve is fastened through a fastening unit, the installation is completed, the rotary excavating tooth can be installed only by one person without other tools, time and labor are saved, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of shield machine accessories, in particular to a new type of rotary digging coal pick for a shield machine. Background technique [0002] Shield machine, the full name is shield tunnel boring machine, is a kind of special engineering machinery for tunnel boring. Modern shield boring machine integrates light, machinery, electricity, hydraulic, sensing and information technology, and has the ability to excavate and cut soil. body, transportation of soil muck, assembly of tunnel lining, measurement guidance and deviation correction and other functions, involving geology, civil engineering, machinery, mechanics, hydraulics, electricity, control, measurement and other disciplines and technologies, and "tailor-made" according to different geology Designed and manufactured with extremely high reliability requirements. Shield boring machines have been widely used in subway, railway, highway, municipal, hydropower ...

AI Technical Summary

Problems solved by technology

[0003] The existing shield machine needs to use the rotary excavator for piling during the initial construction and installation process, and the rotary excavator mainly relies on different types of rotary excavation teeth for piling work, but the existing rotary excavation teeth in the installation process , needs to use a sledgehammer for hammering, or use special installation pliers and circlips for installation, which is time-consuming and laborious, which is not conducive to the rapid replacement of rotary digging teeth and affects the actual project progress. Therefore, in order to solve the above problems, we propose a Shield machine new rotary digging coal pick
