Abstract
The invention provides a mucking and transporting method and device applied to a double-shield tunnel boring machine. The mucking and transporting method comprises the following step: (1) conveying stone ballasts excavated by a cutterhead to a second belt conveyor by utilizing a main belt conveyor; (2) conveying the stone ballasts to a material distribution belt conveyor by the second belt conveyor; and (3) enabling the material distribution belt conveyor to do reciprocating motion along a rail and changing a rotating direction, so as to distribute and fill the stone ballasts into different compartments of a ballast transportation vehicles. The mucking and transporting method and device applied to the double-shield tunnel boring machine have the advantages that a shuttle-type belt conveyer is moved in two directions; compared with the previous loading of the two ballast transportation vehicles, the shuttle-type belt conveyer can load four ballast transportation vehicles when the bidirectional movement is carried out, so that the mucking efficiency is greatly improved; and the material distribution belt conveyor is relatively easy to maintain through a self-tensioning device, so that the labor intensity is relatively low.
Description
Technical field
The present invention relates to a kind of muck removal carrying method being applied to Double shield TBM and device, for ballast is transported tunnel, it is ensured that the high efficiency of TBM constructing tunnel.
Background technology
Double-shielded TBM can realize hard rock tunnel excavation, muck removal, the working continuously of supporting, and because of its performance safe efficient, reliable, has been widely used in now the engineerings such as water conservancy and hydropower, mining, track traffic, municipal administration, national defence.Its main frame is made up of anterior shield, flexible shield, a pole and tail shield four part.Quarrel soil conveying is a ring particularly important in TBM, and the efficiency of muck removal is closely related with feeding efficiency.Therefore, muck removal system reliable, efficient is for most important TBM.Owing to the driving speed of TBM construction is fast, muck removal amount is big, it is therefore desirable to there is a set of suitable muck removal system to match with it.The muck removal system that can effectively be currently used for TBM constructing tunnel mainly has two kinds: locomotive traction rail mounted transport system and belt feeder muck removal transportation system, continuous belt conveyer mucking transportation system is the muck removal mode for distance, the constructing tunnel of large conveying quantity；And in short distance constructing metro tunnel, it is generally the mode that belt feeder combines with locomotive traction rail travel.
Belt feeder transport has following characteristics:
(1) muck removal has seriality, is greatly saved the muck removal time.
(2) construction management is relatively simple, and labor intensity is low, and personnel are few.
(3) will not produce to pollute, ventilation blower and airduct are required low.
(4) it is generally mounted on tunnel top or abutment wall, safeguards inconvenience.
Locomotive traction rail mounted transport system itself has following characteristics:
(1) path material puts into: the transport of rail muck removal is typically in tunnel to arrange single line, two-wire or four rail three lines.Single line is made up of the steel sleeper that two rail and distance are impartial, and two-wire and four rail three lines are made up of the steel sleeper that four rail and spacing are impartial.
(2) restriction of transport capacity: owing to the driving power of locomotive and the capacity of mine car govern the speed of muck removal transport, during distance muck removal, track capacity also limit the transport of quick muck removal.
(3) restriction of the muck removal gradient: the power of locomotive walking is provided by the force of sliding friction between locomotive wheel and track.The coefficient of friction of steel and steel is about 0.15, and this just largely limits the driving power of locomotive, and the general gradient tunnel more than 3% is just not suitable for adopting the muck removal mode of rail travel.
In constructing metro tunnel, have the gradient low, apart from the feature such as short, therefore it is suitable for the mode adopting belt feeder and locomotive traction rail travel to combine, by receiving hopper, ballast concentrated on main belt feeder, then it is delivered to the second belt feeder by main belt feeder, again through the second belt feeder, ballast is transported to quarrel car, is then transported to hole by quarrel car, completes discharging.The discharging efficiency of this kind of muck removal mode depends on the length of the second belt feeder, and namely the length of the second belt feeder determines the quantity in quarrel car compartment, is limited to the size in space shared by quarrel Herba Plantaginis end Gilled tube transporting carriage, cross structure simultaneously.Meanwhile, the muck removal efficiency of rail travel own just lag behind belt feeder transport conevying efficiency, this performance do not mate the performance that seriously govern properties of product.
Currently also there is the muck removal mode (car puller is installed on chassis, stirs quarrel car by cantilever and moves) adopting car puller although this mode can improve muck removal efficiency, but also there is troublesome poeration simultaneously, the shortcomings such as labor intensity is high, and cost is high, troublesome maintenance.
Summary of the invention
The present invention is aiming at rail travel efficiency and belt-conveying efficiency mismatch problem, makes muck removal efficiency double by shuttle-distributing belt feeder.
The technical scheme is that
A kind of muck removal carrying method being applied to Double shield TBM, it is characterised in that comprise the following steps:
(1) with main belt feeder, the ballast that cutterhead excavates is transferred on the second belt feeder；
(2) second belt feeders will be delivered on distributing belt machine；
(3) ballast distribution is loaded in the different compartments of fortune quarrel car by distributing belt machine by moving back and forth and change rotation direction along track.
The device that a kind of described muck removal carrying method being applied to Double shield TBM uses, including main belt feeder, second belt feeder, fortune quarrel car and chassis, the tail end of main belt feeder and the head end of the second belt feeder are corresponding, second belt feeder is arranged on the chassis top of n shape, fortune quarrel car is located on the fortune quarrel track road below the second belt feeder tail end, it is characterized in that, it is provided with distributing belt machine and cloth track between the second described belt feeder tail end and fortune quarrel car, this cloth track is located at this chassis two and founds the middle inside of side, it be arranged in parallel with described fortune quarrel track road, it is provided with road wheel in the both sides of this distributing belt machine, this road wheel is located on cloth track.
Described cloth track adopts channel-section steel, and the opening of both sides channel-section steel is oppositely arranged, and the tread of the road wheel of described distributing belt machine is placed on the lower aerofoil in channel-section steel opening.
The invention have the advantage that by way moving shuttle belt machine, by this way moving, shuttle belt machine, by original two quarrel cars of loading, can load four quarrel cars till now, be greatly improved muck removal efficiency.
