Abstract
A kind of cutterhead water spraying mechanism of tunneling boring rock tunnel development machine, including water spout and the nozzle carrier that is fixedly connected with its rear end, it is characterised in that in one outer barrel of anterior insertion of described water spout, and be threadedly coupled with the outer barrel；Sealing ring is provided between the nozzle carrier and the rear end of the outer barrel.The utility model has the advantages that：Make cutterhead water spraying structure into inner/outer tube shrink-fit structure; when needing to change water spout after water spout blocking; operating personnel do not need retract cylinder fall back anterior shield; manhole cover of dismantling again is changed to face; nozzle carrier only need to be pulled down from cutterhead rear; the time of maintenance shut-downs is reduced, security risk during operating personnel's replacing water spout is reduced.
Description
Technical field
The utility model is related to a kind of cutterhead water spraying structure of tunneling boring rock tunnel development machine, is mainly used in TBM knives
Dedusting, cooling in disk tunneling process.
Background technology
Tunneling boring rock tunnel development machine（Tunnel Boring Machine, hereinafter referred to as TBM）In the water conservancy water of China
The tunnel constructions such as electricity, railway, traffic, city underground engineering, oil-gas pipeline, national defence quickly grow, using increasingly extensive.In tunnel
Road uses TBM construction technologies and equipment in building, and with efficient, high-quality, safety, economy, small to rock disturbance, is conducive to environment
The advantages of protection and reduction labour intensity.
TBM is the integrated equipment for integrating broken rock driving, dregs transportation, section of jurisdiction supporting.In the tunneling process of TBM
In, cut scar and when rolling broken rock when disk cutter, rock dust sprays everywhere from scar, at this moment the temperature of cutter also pole
Height, rock quarrel falls into hole bottom and also kicks up dust.In order to scar goes out dirt and cooling cutter, in cutterhead surface layout series of spray nozzles, use
Water spray suppresses dust, cooling cutter.Current existing technical scheme is to be welded in cutterhead by the water spout seat of an one
On, water spout is installed on front end.
In TBM cutterhead tunneling processes, easily blocked for dedusting, cooling water spout, damaged, at this moment need to shut down more
Change.Need to promote mainly oil cylinder retraction during replacing, anterior shield is retreated, and cutterhead manhole cover of dismantling, operating personnel enter area from cutterhead manhole
Face is changed, and process hazard and wastes time and energy.
The content of the invention
The utility model need to be optimized with the presence of the difficult problem of the repair and replacement of structure for above-mentioned to water injection system
A kind of design, there is provided new cutterhead water spraying mechanism.
The technical solution of the utility model is：A kind of cutterhead water spraying mechanism of tunneling boring rock tunnel development machine, including spray
Water nozzle and the nozzle carrier being fixedly connected with its rear end, it is characterised in that in one outer barrel of anterior insertion of described water spout, and with
The outer barrel is threadedly coupled；Sealing ring is provided between the nozzle carrier and the rear end of the outer barrel.
Described water spout is structure as a whole with nozzle carrier.
The utility model has the advantages that：Make cutterhead water spraying structure into inner/outer tube shrink-fit structure, needed when after water spout blocking
When changing water spout, operating personnel do not need retract cylinder fall back anterior shield, then dismantle manhole cover to face change, only need
Nozzle carrier is pulled down from cutterhead rear, the time of maintenance shut-downs is reduced, peace during operating personnel's replacing water spout is reduced
Full blast danger.
Brief description of the drawings
Fig. 1 is axial cross section structure diagram of the present utility model；
Fig. 2 is dimensional structure diagram of the present utility model.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of cutterhead water spraying mechanism of tunneling boring rock tunnel development machine of the utility model, including spray
Water nozzle 3 and and its rear end（The left side of Fig. 1）The nozzle carrier 1 of one, described the anterior of water spout 3 is inserted in an outer barrel 2, and with
The outer barrel 2 is threadedly coupled；Sealing ring 4 is provided between the nozzle carrier 1 and the rear end of the outer barrel 2.
The utility model when in use, first by the front end of outer barrel 2（Right-hand member in Fig. 1）It is welded on cutterhead, then will spray
In one outer barrel 2 of anterior insertion of water nozzle 3, and it is threadedly coupled with the outer barrel 2, packing ring is passed through between the rear end of nozzle carrier 1 and outer barrel 2
4 sealings.
Key problem in technology point of the present utility model has 2：
First, overall using inside and outside shrink-fit structure, outer barrel 2 is fixed, need to only be pulled down when changing water spout 3 nozzle carrier 1 together with
Water spout 3 is together unloaded.
Second, the front portion between outer barrel 2 and water spout 3（By driving end）By thread seal, the rear end of outer barrel 2（By shield body
End）Sealed using packing ring 4 between nozzle carrier 1.
