Technical field
The present invention relates to Tunnel Engineering machinery equipment field, especially a kind of cutter head of shield machine cleaning device.
Background technique
Shield machine is a kind of rock tunnel(ling) machine using shield method, and the basic functional principle of shield machine is exactly a cylinder
The steel component of body excavates soil when pushing ahead along canal axes, and shell, that is, shield of the cylinder component, it is right
The also unlined Tunnel Section excavated plays a part of temporary support, the pressure of surrounding soil layer is born, sometimes also subject to underground
Hydraulic pressure, the operations such as excavation, casting, lining cutting carry out under the shielding of shield.
The cutter of shield machine is a very important component part, reasonable selection, operation and maintenance to cutter, directly
Decide the quality, progress and engineering cost of excavation work.When tunneling clay layer, clay constantly accumulates on cutterhead shield machine
And form mud cake, cause cutter head of shield machine torque constantly to increase, the growth of cutterhead bearing temperature is too fast, and fltting speed reduction etc. is existing
As, and then may cause bottom surface deformation increase and ground cave-in accident possibly even occur, seriously affect shield-tunneling construction safety.At present
The processing method of cutterhead mud cake is mainly manually abolished in atmospheric pressure or under pressure warehouse entry, but there are biggish for this mode
Construction risk.
As disclosed a kind of device that warehouse entry with pressure cleans in Chinese invention patent CN205762542U, the cleaning device is logical
It crosses ball and socket base to be mounted on the native storehouse partition of shield machine, core and ball and socket base are ball-joint, and cleaning pipe passes through the channel in core
Cutter head of shield machine is rinsed, the flushing angle of the adjustable cleaning pipe of cleaning pipe is swung.In actual use, construction personnel needs
It enters air cushion storehouse to operate the cleaning device being mounted on native storehouse partition, the air pressure in air cushion storehouse is larger, will affect people
Body health.In addition the cleaning device needs to swing cleaning pipe to adjust flushing angle, needs bigger operating space, therefore empty
Between lesser tunnel implement it is limited.
Summary of the invention
The operating space that the applicant requires for above-mentioned existing cutter head of shield machine cleaning device is big, it is impossible to be used in narrow tunnel
Road, the disadvantages of being unfavorable for human health with pressure, provide a kind of structurally reasonable cutter head of shield machine cleaning device, required operating space
Small, construction personnel operates outside air cushion storehouse, avoids by the effects of air pressure in air cushion storehouse.
The technical solution adopted in the present invention is as follows:

It holds in power head assembly, power head assembly is connect by connector with pumping station with extra-high voltage.
As a further improvement of the above technical scheme:
The support tube is the preserved pipeline in air cushion storehouse.
The sealing device is fixedly connected with support tube.
If arterial highway sealing ring is arranged in sealing device.
It is provided with pressing plate between the support and support tube of the sealing device, is equipped at the contact surface of pressing plate and support
Sealing ring.
If arterial highway sealing ring and dustband are arranged in inside the support of sealing device.
Support one end of sealing device is fixed with end cap, and the two junction is provided with bearing.
Several slips are provided on end cap, slips is equipped with clamping device.
Power head assembly is connect with several pumping station with extra-high voltage, several pumping station with extra-high voltage are arranged in parallel.
Check valve is provided between each pumping station with extra-high voltage and power head assembly.
Beneficial effects of the present invention are as follows:
The present invention is by the setting of drilling rod slip on advance frame, and superelevation pressure rotary-spraying nozzle is arranged in drilling rod front end, and drilling rod rear end is set
Power head assembly is set, when shield, which works, to be stopped, power head assembly pushes drilling rod to cutterhead and cleans cutterhead face, is carrying out shield work
When making, power head assembly drives drilling rod to retreat, and superelevation pressure rotary-spraying device is hidden in support tube internal channel, device overall structure is in
Strip, it is compact-sized, it installs and small using required space, it is easy to operate flexible.
Sealing device is arranged in advance frame front end in the present invention, and drilling rod passes through sealing device, and the multiple tracks axis in sealing device is used
Sealing ring is sealed cutterhead working bin storehouse pressure, and the drilling rod of second half section and power head assembly is made to work under normal pressure state,
Therefore, staff can operate power head assembly outside air cushion storehouse under normal pressure state, without being handled into air cushion storehouse, keep away
The influence of air pressure in air cushion storehouse is exempted from.
Present invention utilizes existing equipments to improve, and existing drilling tool is mounted on the sealing of air cushion storehouse by sealing device
On the preserved pipeline of partition, does not need shield machine to be installed interface progress upgrading, the height to cutter head of shield machine can be realized
Pressure rotary-spraying washing and cleaning operation, environmental suitability is strong, has saved shield machine scrap build cost.
