Description
Technical field
The present invention relates to shield machines to match circuits technical field, particularly relates to shield machine pipeline extension apparatus.
Background technique
Currently, shield machine needs to inject sand outside section of jurisdiction in tunneling process at home in existing tunnel Project Shield machine
Slurry to fix stratum, conventional shield machine transports mortar into hole in the construction process, be all by transport marshaling by mortar from
Shield machine internal trailer is transported outside hole, is then pumped with Kaplan and mortar is transported to mortar filling from transport marshaling by mortar
In, mortar is provided for shield machine driving.Marshaling is transported to need outside hole plus injection slurry, to hole in produce slurries, in hole
It is outer to need to stop a large amount of time and complete having bad luck for slurries, and marshaling not only transported slurry is transported, mainly also need
Section of jurisdiction is transported, as the driving distance in tunnel lengthens, will affect the conevying efficiency of section of jurisdiction to a certain extent, and then will affect
The drivage efficiency of entire shield machine, to seriously affect the construction speed of entire project.
Present some shield-tunneling construction projects are directly transported mortar in the filling of the mortar into hole on trailer by pipeline, hole
Interior pipeline is fixed on section of jurisdiction inner wall, by the piping connection on hose and trailer, needs to realize shield by pipeline extension apparatus
Pipeline elongation in structure machine tunneling process.But common pipeline extension apparatus only has pipeline fixed frame, generally requires manually to drag
The recycling of pipeline is realized on trombone slide road, and the manpower that pipeline stores longer needs is bigger, and pipeline memory length is by serious limit
System；In addition, if having a residual mortar inside pipeline, scene it is limited manually can not stretchy, need more manpowers, not only increase
Cost of labor is added, and time-consuming and laborious.
Summary of the invention
For the deficiency in above-mentioned background technique, the present invention proposes shield machine pipeline extension apparatus, solves shield machine note
The technical issues of starching high pipeline cost recovery, low efficiency and grouting pipeline memory length critical constraints.
The technical scheme of the present invention is realized as follows: shield machine pipeline extension apparatus, including being arranged at the top of trailer
Pipeline fixed frame, grouting pipeline are interspersed in pipeline fixed frame, it is characterised in that: further include pipeline movable stand, pipeline movable stand
Between two pipeline fixed frames, grouting pipeline sequentially passes through pipeline fixed frame and pipeline movable stand, and pipeline movable stand passes through
Hoist engine pulling moves up and down.By the way that pipeline movable stand is arranged, it can easily realize the storage of grouting pipeline, stretch and return
It receives；When needing to store grouting pipeline, the Grouting Pipe of storage is interspersed between pipeline fixed frame and pipeline movable stand, is then made
Hoist engine pulls down grouting pipeline, realizes the storage for the grouting pipeline that height rises and falls, can be big by multiple pipeline extension apparatus
Amount ground storage grouting pipeline；When shield machine tunnels forward, the lift rope of hoist engine is separated with pipeline movable stand first, with
The grouting pipeline slip casting of the advance of shield machine, storage is straightened；When needing to recycle grouting pipeline, by the lift rope of hoist engine with
Pipeline movable stand is connected, and then starting hoist engine moves down pipeline movable stand with the drop-down of lift rope, and then slip casting
Pipeline hangs down to storage state, the recycling of achievable grouting pipeline.
Further, it is provided with the idler wheel matched with grouting pipeline in the pipeline fixed frame and pipeline movable stand,
Idler wheel, which is arranged, can make movement of the grouting pipeline above pipeline fixed frame and pipeline movable stand more convenient, hoist engine provide compared with
The storage and recycling of Grouting Pipe can be realized in small pulling force, can effectively extend the service life of grouting pipeline and hoist engine.
Further, the idler wheel is waist type idler wheel.It can be further improved grouting pipeline using waist type idler wheel to pass through
Stability and reliability.
Further, the idler wheel in the pipeline fixed frame is in the arc shooting that Open Side Down, in the pipeline movable stand
Idler wheel be in opening upwards arc shooting.The roller array mode of arc is set, can with the storage of grouting pipeline, extend and
Recycling state is adapted, and can further improve passability, also can avoid the overbending by grouting pipeline.
Further, the idler wheel in the pipeline fixed frame is provided with two column, and the grouting pipeline is interspersed in pipeline and fixes
Between two column idler wheels of frame, a column idler wheel is provided in the pipeline movable stand, the grouting pipeline is lifted in pipeline movable stand
A column idler wheel below.Two column idler wheels are set in pipeline fixed frame, the frictional force that grouting pipeline is subject to can be further decreased, filled
Code insurance card grouting pipeline uses safe and service life；And a column idler wheel is set in pipeline movable stand, it is because pipeline is mobile
Whole gravity of frame are all applied on grouting pipeline, and the lower half surface of grouting pipeline will not generate friction with pipeline movable stand,
Using a column idler wheel can be realized by convenience, and simplify structure, reduce manufacturing cost.
Further, the pipeline movable stand is connected by fixed pulley with the lift rope of hoist engine.Fixed pulley can change
The direction of stress can be installed hoist engine in place by using fixed pulley.
Further, the hoist engine is arranged on trailer pedestrian's platform, and hoist engine is fixed on trailer row by fixed bracket
On people's platform and opposite up and down with pipeline fixed frame, there are two the fixed pulley settings, and a fixed pulley is directly anchored to and pipeline
On the table top of trailer pedestrian's platform immediately below movable stand, another fixed pulley is fixed on the fixed bracket.Hoist engine is set
It sets on fixed bracket, it can be to avoid the normal pass for influencing trailer pedestrian platform.
The present invention can easily realize the storage, stretching, extension and recycling of grouting pipeline by setting pipeline movable stand, can be with
Increase the memory length of grouting pipeline, reduce grouting pipeline recovered frequency, improve the efficiency of pipeline recycling, reduces cost of labor,
Structure is simple, easy to operate, economical and practical.Setting idler wheel can make grouting pipeline above pipeline fixed frame and pipeline movable stand
Movement it is more convenient, hoist engine provides the storage and recycling that Grouting Pipe can be realized in lesser pulling force, can effectively extend slip casting
The service life of pipeline and hoist engine.The roller array mode of arc is set, it can be with the storage, extension and recycling of grouting pipeline
State is adapted, and can further improve passability, also can avoid the overbending by grouting pipeline.Setting two in pipeline fixed frame
Column idler wheel can further decrease the frictional force that grouting pipeline is subject to, fully ensure that grouting pipeline using safe and using the longevity
Life；And a column idler wheel is set in pipeline movable stand, it is to be infused because whole gravity of pipeline movable stand are all applied on grouting pipeline
Starch pipeline lower half surface will not with pipeline movable stand generate friction, using a column idler wheel can be realized by convenience,
And structure is simplified, effectively reduce manufacturing cost.
