It is mobile.
Preceding cutterhead 200 is connect especially by cutterhead gland 210 with hollow spindle 500, and before cutter head center knife 220 is fixed on
On cutterhead 200.
It is moved in order to which cutterhead 300 after inner sleeve axis 510 drives can be achieved, is removably set in the end of inner sleeve axis 510
There is axis to draw lid 511, drawn in axis and be equipped with several high-intensitive pull rods 512 on lid 511, these high-intensitive pull rods 512 respectively with rear knife
Disk 300 is attached by bolt.
It is respectively equipped with preceding copper sheathing 310 and rear copper sheathing 320 at rear 300 both ends of cutterhead, preceding copper sheathing 310 is supported on preceding cutterhead 200
Outside, rear copper sheathing 320 are supported on outside hollow spindle 500, and preceding copper sheathing 310 and rear copper sheathing 320 are the guiding for rear cutterhead 300
It is wear-resisting.
In addition, being respectively equipped with J-type dustband and Yx type sealing ring in preceding copper sheathing 310 and rear copper sheathing 320, can prevent in this way
Native storehouse muddy water enters 201 internal corrosion spline 201 of spline, improves leakproofness.
Furthermore in telescopic process, rear cutterhead 300 can drive preceding copper sheathing 310 and rear copper sheathing 320 to be moved forward and backward, in preceding copper
The mobile position of set 310 and rear copper sheathing 320 is equipped with chromium plating hardened wear-resistant layer, to protect to preceding copper sheathing 310 and rear copper sheathing 320
Shield, can be improved service life in this way.
Cutterhead shell 400, specifically can be used existing structure, before being set on cutterhead 200, and with rear 300 phase of cutterhead
Cooperation.
Primary fragmentation structure 610 can be formed between the centrum back side of preceding cutterhead 200 before the centrum of cutterhead shell 400,
The cataclasitlc structure is specifically also existing structure.
And apply also adding second-time breakage structure 620, it is secondary to be specifically equipped with several crescent in rear 300 tail portion of cutterhead
Breaker bars 330, and in cutterhead shell 400 be equipped with several crescent second-time breakage rings, these crescent second-time breakage rings with
The mutual cooperation of crescent second-time breakage item 330 can form second-time breakage structure 620.
Concretely dregs arranges wan access in gap among second-time breakage structure 620, and when machine moves forward, dregs can
It is squeezed by front band pressure soil to rear portion slag-drip opening 710 along slope；Second-time breakage structure 620 can will squeeze into gap simultaneously
Rock pass through 620 shearing-crushing of second-time breakage structure.
In this way, the application can be moved forward and backward by flexible rear cutterhead 300 to realize by the implementation of above structure, thus
Realize that the second-time breakage mouth of second-time breakage structure 620 is slagged tap the change in space, can effectively adjust the viscosity of the preceding storehouse soil body with
Pressure improves the mobility of front dregs, and mobile by rear cutterhead 300, can effectively control Tu Cang and cutterhead front soil
The pressure of body, to effectively avoid the problem that surface subsidence.
Muddy water storehouse 700 and water inlet centrum 800 is respectively set in rear 300 tail portion of cutterhead, slag-drip opening is set on muddy water storehouse 700
710, the native storehouse 810 of delay can be formed by intaking between centrum 800 and preceding cutterhead 200, integrated setting with this configuration, it can be achieved that
Effectively water inlet deslagging is effectively controlled according to the mobility selective control deslagging space of geological conditions and the soil body to smooth deslagging
Soil pressure processed, effective real-time feedback control front pressure, avoids surface subsidence while cutting deslagging.
In order to realize, the control to preceding cutterhead 200 and rear cutterhead 300, the application change telescopic oil cylinder 100 respectively
Into.
Telescopic oil cylinder 100 specifically includes cylinder body 110, piston 120, bearing block 130, guide sleeve 140,150 and of thrust bearing
Gland 160.
Piston 120 is arranged in cylinder body 110, and bearing block 130 is equipped with by gland 160 and round nut in cylinder body 110
Tail portion, inner sleeve axis 510 may pass through piston 120, and is integrated by bearing block 130 and gland 160 and mating connection.
Thrust bearing 150 is separately positioned on the both ends of piston 120, and one end and inner sleeve axis 510 are cooperatively connected, the other end and axis
The mating connection of seat 130 is held, thrust bearing 150 is used to transmit inner sleeve axis 510 and moves forward and backward rotary motion between piston 120.
Guide sleeve 140 is separately fixed at the both ends in cylinder body 110, and both ends, which are supported on, during piston 120 moves forward and backward leads
Into set 140.
Piston 120 moves forward and backward under the action of hydraulic oil in this way, so that inner sleeve axis 510 is driven to move forward and backward, it is final real
Now after cutterhead 300 back-and-forth motion, and between cylinder body 110 and hollow spindle 500 by 501 fixed delivery torque of connecting flange with
Power.
In addition, being equipped with a plate 900 outside cylinder body 110, U-lag is equipped with outside bearing block 130, plate 900 can pacify
It injects in U-lag, for preventing bearing block 130 from inner sleeve axis 510 being followed to rotate.
In the fixing end of 900 outside fixed journey system sensor 910 of plate, 910 tache motorice of stroke sensor is fixed on bearing
On the U-lag of seat 130, cylinder movement of the stroke sensor 910 for real-time monitoring is displaced, i.e., what rear cutterhead 300 moved forward and backward
Real-time displacement can understand deslagging pressure in real time in this way.
