Description
Technical field
The present invention relates to shield equipment manufacturing technical fields, particularly relate to a kind of normal pressure tool changing cutterhead for having the function of to slip slag
Auxiliary girder.
Background technology
With continuous improvement of the urban development to public transport demand, using high hydraulic pressure environment as outstanding feature wear river, across
The construction successively of extra large tunnel, to adapt to high hydraulic pressure construction environment, the shield machine for being equipped with normal pressure tool changing cutterhead knife is employed herein
In the construction in class tunnel.Normal pressure tool changing cutterhead has the characteristics that tool changing is fast, safe, but itself aperture opening ratio is small, only for 20%~
30%, cutterhead thickness is big, generally 1.8m~2.2m, causes native from the dregs that face drops from cutterhead front panel to shield machine
The flowing in storehouse is slow, it is impossible to the dregs discharged in time cutterhead front panel bottom accumulate, cutterhead rotate when cutterhead, cutter repeatedly
With accumulation dregs effect, cause the abrasion aggravation of cutterhead, cutter, cutterhead girder is made to face the risk being worn through, is caused serious
Security incident, and cutting-tool's used life can be reduced, while slower dregs flow rate is low not only constrains shield machine
Deslagging efficiency, and the easy mud lining of cutterhead, mud cake, which once generates, will seriously affect cutterhead drivage efficiency.
In order to improve flow rate of the dregs from cutterhead front panel to shield machine Tu Cang, the present invention devises one kind and can slip
The normal pressure tool changing cutterhead auxiliary girder of slag, the auxiliary girder can scoop up dregs, and when cutterhead turns to certain angle, dregs slips slag through auxiliary girder
Slot slips storehouse of burying.
The content of the invention
The present invention proposes a kind of normal pressure tool changing cutterhead auxiliary girder for having the function of to slip slag, solve normal pressure tool changing cutterhead dregs by
Cutterhead front panel to native storehouse flow rate it is slow the problem of.
The technical proposal of the invention is realized in this way：
A kind of normal pressure tool changing cutterhead auxiliary girder for having the function of to slip slag, including cutterhead, girder and auxiliary girder, girder and auxiliary girder are on cutterhead
It is arranged alternately, scraper is provided on girder, the rear portion of cutterhead connects Tu Cang, normal pressure is provided on girder and replaces cutter, auxiliary girder bag
Tool apron plate, slag-screening board and slag trap are included, the side wall of slag-screening board is vertically set on the middle part of slag trap, and the both sides on slag-screening board top are set
Tool apron plate is put, cutter is provided on the outside of tool apron plate.
Large circle is provided on the outside of the girder and auxiliary girder.
The tool apron plate is Curved plate, and one end of tool apron plate overlaps large circle, the other end overlap joint slag trap of tool apron plate.
Grid I, grid II, grid III are provided between described two adjacent girders.
The bottom of the slag-screening board and slag trap is overlapped on ring muscle.
It is hobboing cutter or tearing cutter that the normal pressure, which replaces cutter,.
The girder and auxiliary girder have been uniformly arranged on cutterhead at six.
The large circle of the present invention forms scraper bowl shape structure with slag trap, tool apron plate, and cutterhead continues in the shield course of work
It rotates, a certain auxiliary girder is minimum by being rotated down to compared with the extreme higher position in cutter head center rotary course in rotation process
Point, when being contacted with the dregs of accumulation below cutterhead, the dregs of the auxiliary girder one side initially enters scraper bowl shape structure and slagging tray；The pair
Beam continues rotation to horizontal level, and the dregs in subsequent time scraper bowl shape structure and slagging tray starts oriented cutterhead rear slide
Trend；During the auxiliary girder is rotated from horizontal level to cutterhead peak, in the scraper bowl shape structure and the slagging tray
Dregs slid along the slagging tray to Tu Cang.
The slag normal pressure tool changing cutterhead auxiliary girder that slips of the present invention solves stream of the dregs from cutterhead front panel to shield machine Tu Cang
Move the problem of rate is slow so that the shield machine that normal pressure tool changing cutterhead is equipped with to adapt to high hydraulic pressure environment is ensureing tool changing security
While improve drivage efficiency；Repeated action between the dregs to drop The present invention reduces cutterhead, cutter and face, drop
The risk that low cutterhead girder is worn through, while cutter life is improved, number of changing knife is reduced, has saved and has been constructed into
This, shortens the construction period；Present invention decreases normal pressure tool changing cutterhead incrusted probability at work, make normal pressure tool changing cutterhead
Drivage efficiency get better protection.
