Normal-pressure tool changing cutter secondary beam with slag sliding function

Abstract

The invention provides a normal-pressure tool changing cutter secondary beam with a slag sliding function, and aims to solve the problem that the flow rate of normal-pressure tool changing cutter slagfrom a front panel of a cutter to a soil warehouse is low. The secondary beam comprises the cutter, primary beams and secondary beam bodies, the primary beams and the secondary beam bodies are alternately arranged on the cutter, scrapers are arranged on the primary beams, the soil warehouse is connected with the rear of the cutter, normal-pressure changing tools are arranged on the primary beams,the secondary beam bodies comprises tool apron plates, slag sliding plates and slag retaining plates, the side walls of the slag sliding plates are vertically arranged in the middles of the slag retaining plates, the tool apron plates are arranged on two upper sides of the slag sliding plates, and cutting knives are arranged on the outer sides of the tool apron plates. The normal-pressure tool changing cutter secondary beam with the slag sliding function solves the problem that the flow rate of the slag from the front panel of the cutter to the soil warehouse of a shield tunneling machine islow, so that shield tunneling machine is provided with a normal-pressure tool changing cutter in order to adapt to high-water-pressure environments and improves tunneling efficiency when tool changingsafety is ensured.

Description

technical field [0001] The invention relates to the technical field of shield tunneling equipment manufacturing, in particular to a sub-beam of an atmospheric tool changing cutterhead with the function of slag sliding. Background technique [0002] With the increasing demand for public transportation due to urban development, river-crossing and sea-crossing tunnels featuring high water pressure environments are being constructed one after another. In order to adapt to the high water pressure construction environment, shield machines equipped with atmospheric pressure tool changer cutters Machines are used in the construction of such tunnels. Atmospheric pressure tool change cutter head has the characteristics of fast and safe tool change, but its own opening ratio is small, only 20% to 30%, and the thickness of the cutter head is large, generally 1.8m to 2.2m, resulting in falling from the hole surface. The dregs flow slowly from the front panel of the cutter head to the so...
