Abstract
The inner dross extractor of a kind of tunnel piercing main beam be applied in tunnel machine field, comprise passive sheave, afterbody support body, scraper plate group, middle part support body, head support body, head driving, batch turning plate, afterbody support body, middle part support body, head support body are bolted on and are welded to girder inside together, passive sheave is arranged on afterbody support body, head drive installation is on head support body, scraper plate group is arranged on the track of afterbody support body, middle part support body, head support body composition, and batch turning plate is arranged on head and drives below and head support body rear end.This apparatus structure is simple, efficiency is higher, and fast can clear up the inner body refuse of girder easily, dross extractor is by fluid motor-driven sheave, drive the scraper plate on chain to carry out work, the body refuse that girder inside is saved bit by bit can be removed according to the rail moving of girder indoor design by scraper plate fast.
Description
Technical field
The utility model relates to the inner dross extractor of a kind of tunnel piercing main beam in tunnel machine field.
Background technology
When tunnel machine normally carries out headwork, while conveyor transport slag charge, belt also carry a part of body refuse in return stroke, every day splashes down by driving 20m distance body refuse and thickness in girder inside will reach 120mm ~ 150mm, if the body refuse that time this thickness is stacked into 300mm, return idler will be deposited blocks, considerable damage will be produced to conveyor.Because girder inner space is less, prune job very difficult (needing workman to lie prone at girder internal cleaning).Invention fast, easily the inner slag cleaning device of girder seem very there is practical significance.Therefore, developing the inner dross extractor of a kind of tunnel piercing main beam is a new problem anxious to be resolved.
Summary of the invention
The purpose of this utility model is to provide the inner dross extractor of a kind of tunnel piercing main beam, this utility model structure is simple, efficiency is higher, fast can clear up the inner body refuse of girder easily, dross extractor is by fluid motor-driven sheave, drive the scraper plate on chain to carry out work, the body refuse that girder inside is saved bit by bit can be removed according to the rail moving of girder indoor design by scraper plate fast.
The purpose of this utility model is achieved in that the inner dross extractor of a kind of tunnel piercing main beam, comprise passive sheave, afterbody support body, scraper plate group, middle part support body, head support body, head driving, batch turning plate, afterbody support body, middle part support body, head support body are bolted on and are welded to girder inside together, passive sheave is arranged on afterbody support body, head drive installation is on head support body, scraper plate group is arranged on the track of afterbody support body, middle part support body, head support body composition, and batch turning plate is arranged on head and drives below and head support body rear end.
Main points of the present utility model are its structure.Its operating principle is: utilize hydraulic motor that inner for girder rock slag, muddy water are transported to girder rear portion by scraper plate and get rid of.In TBM work progress, a small amount of rock slag can be retained in belt surface during the running of main frame conveyor, muddy water splashes down at girder inner by return belt.Although muddy water amount is little, in TBM tunneling process, conveyor can operate continuously, can cause serious wearing and tearing to return belt, return idler and then cause TBM shutdown maintenance after taking care of the pence.TBM often tunnels the muddy water that 20m can produce 1m3.The muddy water viscosity produced due to rock slag is comparatively large in addition inner at girder, and cleaning is got up very difficult.The inner dross extractor of girder well solves this problem, and it can each driving stroke cycle start once, clears up rock slag, muddy water easily, ensures girder cleaning inside.
The inner dross extractor of tunnel piercing main beam compared with prior art, there is structure simple, efficiency is higher, fast can clear up the inner body refuse of girder easily, dross extractor is by fluid motor-driven sheave, drive the scraper plate on chain to carry out work, the body refuse that girder inside is saved bit by bit the advantage such as can be removed according to the rail moving of girder indoor design by scraper plate fast, can be widely used in tunnel machine field.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 I place afterbody sheave parts enlarged drawing.
Fig. 3 is Fig. 1 II place head drive part enlarged drawing.
Fig. 4 is support body and scraper plate group A-A sectional view in the middle part of Fig. 1.
Detailed description of the invention
With reference to accompanying drawing, the inner dross extractor of a kind of tunnel piercing main beam, comprise passive sheave 1, afterbody support body 2, scraper plate group 3, middle part support body 4, head support body 5, head driving 6, batch turning plate 7, afterbody support body 2, middle part support body 4, head support body 5 are bolted on and are welded to girder inside together, passive sheave 1 is arranged on afterbody support body 2, head drives 6 to be arranged on head support body 5, scraper plate group 3 is arranged on the track of afterbody support body 2, middle part support body 4, head support body 5 composition, and batch turning plate 7 is arranged on below head driving 6 and head support body 5 rear end.
Its using method is: the utility model is applied to tunnel machine, afterbody support body 2, middle part support body 4, head support body 5 are bolted formation integral-rack, provide support for scraper plate group and lead, head drives 6 to provide power source for scrapper conveyor, drive passive sheave 1 and scraper plate group 3 by body refuse from the inner scraping of girder out, be transported on post-matching leather belt machine by batch turning plate 7.
