Description
Technical field
The utility model relates to shield machine ventilating dust-arrester technical fields, and it is solid to particularly relate to a kind of flexible pneumatic hose of TBM
Determine device.
Background technique
TBM shield machine mainly applies to ground consisting of hard rock construction, is rotated by cutterhead and drives the cutters such as hobboing cutter, scraper to area
Face hard rock is broken to be excavated, and is then carried out rubble by belt feeder.Due to cutter and face in TBM work progress
The scraping of hard rock can generate a large amount of dust, and very big influence is caused to tunnel construction environment, if not in time handled dust
Fall, the worker's body that constructed in tunnel can be caused to damage, and goes down also to will affect the normal use of equipment for a long time.Institute
With, TBM equipment is typically equipped with dedusting fan, and dedusting fan is docked by pneumatic hose and hard air hose with the slag notch of belt feeder,
Take the dust that excavation face in construction generates away processing.
Air hose both ends are hard air hoses, are separately connected dedusting fan and belt feeder slag notch, and centre is that pneumatic hose is in host
With coaster junction, host is goed ahead by dilatory oil cylinder with coaster.When dilatory oil cylinder stretches out, pneumatic hose stretching, extension, dedusting
Blower can normally extract dust out.But when dilatory oil cylinder is shunk, distance reduces between host and coaster, pneumatic hose
And then it shrinks.When dedusting fan work, negative pressure will form in air hose, pneumatic hose can overlap one under the action of negative pressure at this time
Rise, block Dustproof air flue, cause dust removing effects to reduce, in addition cause dedusting fan exhausting it is unsmooth, fever stop working, influence whole
The construction efficiency of a shield.

Hard air hose is equipped with flexural pivot before described, and the front end of crossbeam is connected with flexural pivot.Realize crossbeam front end energy
Enough it is freely rotated.
Hard air hose is equipped with sliding support after described, and the rear end of crossbeam, which passes through sliding support and slides with sliding support, to be connected
It connects.Crossbeam can be moved forward and backward between sliding.
The crossbeam lower part is equipped with sliding slot, Slip Hook is equipped in sliding slot, Slip Hook and snap ring correspond, and snap ring is hooked on cunning
On hook.Slip Hook can slide in sliding slot, and snap ring blocks pneumatic hose, and is connected by Slip Hook with crossbeam.
The flexural pivot and sliding support are located in same vertical plane.Prevent crossbeam from twisting.
Hard air hose is fixed on coaster by fixed frame after described.
The utility model uses can be with the crossbeam of host motion, and Slip Hook is used to realize the flexible connection of pneumatic hose, prevents
Pneumatic hose shrinks overlapping blocking Dustproof air flue when dedusting fan works, and guarantees that dedusting fan normally and efficiently works, improves applying for TBM
Work efficiency rate.The front end of crossbeam is flexural pivot connection type, can more preferably guarantee that pneumatic hose works normally when TBM turns, and does not weigh
It stacks, guarantees the unimpeded of Dustproof air flue.The utility model structure is simple, reduces manufacturing cost, and realizes the servo-actuated of air hose
Flexibly, dust removing effects are substantially improved.
Detailed description of the invention
It, below will be to attached drawing needed in embodiment description in order to illustrate more clearly of the utility model embodiment
It is briefly described, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is A direction view in Fig. 1.
Fig. 3 is the utility model crossbeam and sliding support attachment structure schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1, as illustrated in fig. 1 and 2, a kind of flexible light air pipe fixing device of TBM, including preceding hard air hose 9 and rear hard wind
Pipe 1, preceding hard air hose 9 are connected by pneumatic hose 5 with rear hard air hose 1, and dedusting channel is formed.Hard air hose 9 goes out with belt before described
Cinder notch 11 is connected, and rear hard air hose 1 is fixedly connected by fixed frame 2 with coaster 13.Coaster passes through dilatory oil cylinder 12 and host 10
