Embodiment
For the technical characterstic for illustrating this programme can be understood, below by an embodiment, and its accompanying drawing is combined, it is right
This programme is illustrated.
Hobboing cutter serrated knife exchanges process, including following operating procedure under a kind of compound stratum shield normal pressure：
Step one, knife cylinder is rinsed, the purpose for rinsing knife cylinder is to clean out the silt between interior knife cylinder and outer knife cylinder, to avoid
Interior knife cylinder is blocked in motion process by silt；
Step 2, fixed oil cylinder, oil cylinder is as power part, and the motion for knife cylinder provides certain pulling force；
Step 3, unclamps knife cylinder bolt；
Step 4, withdraws oil cylinder, lifts by crane knife cylinder, the withdrawal oil cylinder of this step is that knife cylinder is recovered into position of strobe；
Step 5, flush gate, the purpose of flush gate is to rinse the silt in gate and gate neck well, it is to avoid gate
Gai Buyan or the phenomenon do not covered；
Step 6, closed shutter, after closing gate, the anterior mud UNICOM that will be with face of gate, the front portion of gate
For higher-pressure region, the rear portion of gate is atmospheric area, and operating personnel carry out the replacing of cutter in atmospheric area；
Pressure difference between in step 7, balance gate and outside gate；
Step 8, thoroughly withdraws oil cylinder, and the withdrawal oil cylinder of this step is to be completely pulled out knife cylinder；
Step 9, removes oil cylinder and interim storage；
Step 10, knife cylinder is fully drawn out；
Cutter on step 11, more tool changing cylinder；
Step 12, installs knife cylinder.
It is different according to the Cutting trajectory of cutter, it is also different to the dismounting step of cutter and instrument used during tool changing.
The first embodiment：
Step one, see Fig. 1, water pipe is connected with the flushing ball valve 1 on knife cylinder 5, open and rinse the flushing knife of ball valve 1 cylinder 5, rinsed
Closed after finishing and rinse ball valve 1 and remove water pipe, close wear detection ball valve 2（For detecting whether cutter weares and teares）, then remove
Wear detection pipeline；
Step 2, is shown in Fig. 2, and oil cylinder 4 is sling using tool changing loop wheel machine, makes oil cylinder 4 with oil cylinder fixing base 3 in sustained height, using even
Oil cylinder 4 is fixed on oil cylinder fixing base 3 by fitting 6, and locked with pin；
Step 3, is shown in Fig. 3, it is ensured that the locking mechanism of the afterbody of oil cylinder 4 with chain in the horizontal direction, by control valve and the pipe of oil cylinder 4
Road is attached, and the piston rod of control cylinder 4 stretches out and is connected with knife cylinder 5, by locking mechanism controls at 1 grade, it is ensured that walk above
After rapid, to knife cylinder bolt on some point pressures to oil cylinder 4, is then unclamped, the purpose of control valve described in this step is to be used to control
Liquefaction cylinder piston rod it is flexible；
Step 4, is shown in Fig. 4, and the piston rod 4.1 of control cylinder 4 is retracted to the position of gate 26 with moving knife cylinder 5（#1-#18 knives are about
435 mm are withdrawn, #25/26 knives about withdraw 695mm）, knife collet chuck tool 7 is fixed on knife cylinder 5, by the suspension hook of air hoist 8
Hang on knife collet chuck tool 7, and air hoist 8 is taken power, by knife cylinder bracket（Because the gross weight of knife cylinder 5 and knife is larger, 1 is weighed
Ton is more, to avoid the failure of air hoist 8 from producing security incident, so there is provided knife cylinder bracket）It is fixed on 5 bottoms of knife cylinder（At least
Use 3 M27 X 100 bolt）；
Step 5, is shown in Fig. 4, on the flushing line that water pipe is connected to gate 26, opens the flushing ball valve on flushing line to rush
Gate 26 is washed, after flushing is finished, closes and rinses ball valve, and remove water pipe；
Step 6, is shown in Fig. 5, and control valve is connected with the pipeline of gate 26, removes the yellow protective case on gate oil cylinder piston rod,
Gate 26 is shut, shut after gate 26, it is ensured that gate clamping screw is locked, in this step, the effect of control valve is to be used to control
Liquefaction pressure, and then the open and-shut mode of regulating gate 26, gate oil cylinder drive the opening and closing of gate 26, normal driving state tail gates 26
It is to open, gate piston rod is pounded to avoid during driving state part bolt from dropping, so early stage can be equipped with yellow protective case；
Step 7, is shown in Fig. 6, and ball valve 1.1 is opened with the inside and outside differential pressure of balance gate 26, after inside and outside differential pressure balance, by ball valve 1.1
Shut, by locking mechanism controls at 2 grades；
Step 8, is shown in Fig. 7,4 two withdrawals completely of control cylinder；
Step 9, is shown in Fig. 8, removes connector 6, oil cylinder 4 is separated with fixed seat, hung oil cylinder 4 using second air hoist
Rise and be temporarily stored to a suitable position, oil cylinder 4 and other weights should not must be placed on the distachable platform of tool changing；
Step 10, is shown in Fig. 9, and knife cylinder 5 is fully drawn out（Notice that knife cylinder 5 can be rocked or swung after extracting out）, and it is transported to material fortune
Defeated passage；
Cutter on step 11, more tool changing cylinder 5；
Step 12, installation operation is carried out to changing the knife cylinder 5 after cutter.
The installation of knife cylinder 5 is substantially the contrary operation that knife cylinder 5 is removed, but is the steps of having to carry out in place：（1）Knife
When cylinder 5 puts into gate valve body, without jam plate is locked into 2 grades, knife cylinder 5 is put into before gate valve body, must be by inside gate
（It can contact）Clean out, and smeared 5 outer surfaces of knife cylinder completely completely using machine oil or butter：（2）Open gate 26 it
Before, water is filled in the small space between knife cylinder 5 and gate 26 by the flushing ball valve 1 on knife cylinder 5, added hydraulic pressure need to be with the palm
Sub- surface pressure is consistent；（3）During adding water, the ball valve 1.1 on flushing line on knife cylinder 5 need to be opened so that gas is arranged
Go out；（4）When the space between knife cylinder 5 and gate 26 fills its water of water from when rinsing the spilling of ball valve 1, flushing line ball is shut again
Valve；（5）When knife cylinder 5 is promoted into gate valve body, notice that alignment pin must be consistent with gate valve body upper Positioning holes on knife cylinder 5（Note
The position of alignment pin）.
Locking mechanism is locked in 1 grade and 2 grades, wherein 1 grade and 2 grades equivalent to two limiters, locking mechanism is locked in 1 grade
When oil cylinder 4 can only be recovered to a specified location, oil cylinder 4 can only be recovered to another specific bit when locking mechanism is scheduled on 2 grades
Put.
