The center flushing device for the center-closed cutter is convenient to use, easy in manufacturing and good in use effect.

Description

A kind of Central Closed formula cutter head center flushometer
Technical field
The invention belongs to tunnel shield machine tunneling technique field, be specifically related to a kind of Central Closed formula cutter head center flushometer.
Background technology
In recent years, shield-tunneling construction affects the features such as little, driving speed is fast, ground settlement is little with it to ground and underground environment, is widely used in subterranean tunnel construction.Cutterhead on shield machine has polytype, Central Closed formula cutterhead to be the cutterheads that a kind of number of applications is a lot, but this cutter head center region belongs to enclosed construction, and dregs does not has relative motion, easy mud lining in central area.
Therefore, the sediment improvement means strengthening cutter head center region have just become a problem that have to solve.
Summary of the invention
For above-mentioned deficiency described in the prior, the invention provides can the dregs of quick flush improved knife central area, prevent the dregs molding in cutter head center, economic and practical, the Central Closed formula cutter head center flushometer of work efficiency can be effectively improved.
For realizing above-mentioned technical purpose, the technical solution adopted in the present invention is as follows:
A kind of Central Closed formula cutter head center flushometer, including little swivel coupling, big swivel coupling, transition piece, cutterhead flange and spout, little swivel coupling is arranged on big swivel coupling and is connected in series with big swivel coupling, big swivel coupling is fixed on transition piece, transition piece is fixed on cutterhead flange, and spout is arranged on cutterhead flange, and the passage I of little swivel coupling docks with the passage II of big swivel coupling, passage II docks with the passage III on transition piece, and passage III is connected with spout.
Described spout includes that spout I and spout II, spout I and spout II are arranged on cutterhead flange, and described passage III is divided into two-way, and a road is connected with spout I, and pipeline of separately leading up to is connected with spout II.
Described spout I includes that body I, body I are arranged in the installing hole I of cutterhead flange, and the rear end of body I is connected with a road of passage III, and the front end of body I is provided with check valve rubber.The check configuration of spout I can effectively prevent dregs from resulting in blockage in entering spout I, affects sediment improvement effect.
Described spout II includes that body II, body II are removably mounted in the installing hole II of cutterhead flange, and the top of body II is connected with another road of passage III by pipeline, and the front end of body II is provided with check valve rubber, and the rear end of body II is provided with globe valve.The check configuration of spout II can effectively prevent dregs from resulting in blockage in entering spout II, affects sediment improvement effect.And can be dredged by globe valve after spout II blocking, spout II is removably mounted on cutterhead flange, can be split out by spout II and be replaced after the check valve rubber of spout II front end thoroughly damages.
The present invention is connected in series with big swivel coupling by little swivel coupling, and the passage I of little swivel coupling docks with the passage II of big swivel coupling, and passage II docks with the passage III on transition piece, and passage III is connected with spout.Water source enters from the import of little swivel coupling, spray from spout I and spout II through passage I, passage II and passage III, dregs in closed cutter head center is improved, effectively prevents dregs molding, improve work efficiency, and the present invention is overall with cutterhead flange rotary, do not result in pipeline to be wound around, reduce rate of breakdown, and the present invention is easy to use, making simple, using effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of spout II of the present invention.
Detailed description of the invention
As shown in Figure 1-2, a kind of Central Closed formula cutter head center flushometer, including little swivel coupling 1, big swivel coupling 2, transition piece 3, cutterhead flange 4 and spout, little swivel coupling 1 is arranged on big swivel coupling 2 and is connected in series with big swivel coupling 2, big swivel coupling 2 is fixed on transition piece 3, transition piece 3 is fixed on cutterhead flange 4, spout is arranged on cutterhead flange 4, passage I 1-1 of little swivel coupling 1 docks with passage II 2-1 of big swivel coupling 2, passage II 2-1 docks with passage III 3-1 on transition piece 3, and passage III 3-1 is connected with spout.
In the present embodiment, described spout includes that spout I 5 and spout II 6, spout I 5 and spout II 6 are arranged on cutterhead flange 4, and described passage III 3-1 is divided into two-way, and a road is connected with spout I 5, and pipeline of separately leading up to is connected with spout II 6.
Specifically, described spout I 5 includes that body I, body I are arranged in the installing hole I of cutterhead flange 4, and the rear end of body I is connected with a road of passage III 3-1, and the front end of body I is provided with check valve rubber.The check configuration of spout I 5 can effectively prevent dregs from resulting in blockage in entering spout I 5, affects sediment improvement effect.
Described spout II 6 includes body II, body II is removably mounted in the installing hole II of cutterhead flange 4, the top of body II is connected with another road of passage III 3-1 by pipeline, and the front end of body II is provided with check valve rubber, and the rear end of body II is provided with globe valve 6-1.The check configuration of spout II 6 can effectively prevent dregs from resulting in blockage in entering spout II 6, affects sediment improvement effect.And can be dredged by globe valve after spout II 6 blocking, spout II 6 is removably mounted on cutterhead flange, can be split out by spout II 6 and be replaced after the check valve rubber of spout II 6 front end thoroughly damages.
Operation principle: water under high pressure is connected to the import of little swivel coupling 1 by pipeline, water under high pressure enters transition piece 3 through passage I 1-1 and passage II 2-1, and pass through the spout I 5 from cutterhead flange 4 of passage III 3-1 on transition piece 3 and spout II 6 ejection, the dregs of improved knife central area, reduces incrusted probability;The pipeline of water under high pressure cannot connect directly to the spout on cutterhead flange, because cutterhead flange is a rotating mechanism, if be connected on cutterhead flange by the pipeline of water under high pressure, when cutterhead flange rotary, the pipeline of water under high pressure can be twisted into twisted shape.The globe valve 6-1 of spout II 6 rear end is closed time flat, once there is the situation of spout II 6 blocking, spout II 6 can be dredged by globe valve 6-1, and spout II 6 is designed as removably formula, after the check valve rubber of spout II 6 front end thoroughly damages, spout II 6 can be split out replacing.
