Specific embodiment
In order to clarify the technical characteristics of the invention, below by a specific embodiment, and its attached 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 1 rinses knife cylinder, and the purpose for rinsing knife cylinder is to clean out the silt between interior knife cylinder and outer knife cylinder, with
Interior knife cylinder is avoided to be blocked during the motion by silt；
Step 2, fixed oil cylinder, oil cylinder provide certain pulling force as power part, for the movement of knife cylinder；
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 to position of strobe；
Step 5, flush gate, the purpose of flush gate are to rinse the silt in gate and gate card slot well, are avoided
Gate Gai Buyan or the phenomenon that do not cover；
Step 6, closed shutter, after closing gate, the front of gate will with the mud connection of face, gate
Front is higher-pressure region, and the rear portion of gate is atmospheric area, and operator carries out the replacement of cutter in atmospheric area；
Step 7, in balance gate and gate it is outer between pressure difference；
Step 8, thoroughly withdraws oil cylinder, and the withdrawal oil cylinder of this step is to be completely pulled out knife cylinder；
Step 9 is removed oil cylinder and is temporarily stored；
Step 10, knife cylinder are fully drawn out；
Step 11, the cutter on more tool changing cylinder；
Step 12 installs knife cylinder.
Different according to the Cutting trajectory of cutter, when tool changing, is also different to the dismounting step of cutter and tool used.
The first specific embodiment:
Step 1 is shown in Fig. 1, and water pipe is connected with the flushing ball valve 1 on knife cylinder 5, opens and rinses the flushing knife cylinder 5 of ball valve 1, punching
It is closed after washing and rinses ball valve 1 and remove water pipe, closed wear detection ball valve 2 (for detecting whether cutter wears), then
Remove wear detection pipeline；
Step 2 is shown in Fig. 2, slings oil cylinder 4 using tool changing loop wheel machine, makes oil cylinder 4 and oil cylinder fixing base 3 in sustained height, adopts
Oil cylinder 4 is fixed on oil cylinder fixing base 3 with connector 6, and locked with pin；
Step 3 is shown in Fig. 3, it is ensured that the locking mechanism of 4 tail portion of oil cylinder and chain in the horizontal direction, by control valve and oil cylinder 4
Pipeline be attached, control oil cylinder 4 piston rod stretch out simultaneously is connect with knife cylinder 5, by locking mechanism controls at 1 grade, it is ensured that with
After upper step, 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 use
In the flexible of control cylinder piston rod；
Step 4, is shown in Fig. 4, controls the piston rod 4.1 of oil cylinder 4 and with moving knife cylinder 5 is retracted to 26 position of gate (#1-#18 knife is big
435mm is about withdrawn, #25/26 knife about withdraws 695mm), knife collet chuck tool 7 is fixed on knife cylinder 5,8 suspension hook of air hoist is hung
On knife collet chuck tool 7, and air hoist 8 is made to take power, knife cylinder bracket (because the total weight of knife cylinder 5 and knife is larger, is weighed 1 ton
It is more, to avoid the failure of air hoist 8 from generating safety accident, so being provided with knife cylinder bracket) be fixed on 5 bottom of knife cylinder and (at least make
With the bolt of 3 M27X 100)；
Step 5 is shown in Fig. 4, water pipe is connected in the flushing pipeline of gate 26, opens the flushing ball valve in flushing pipeline
Carry out flush gate 26, after flushing, closes and rinse ball valve, and remove water pipe；
Step 6 is shown in Fig. 5, and by the piping connection of control valve and gate 26, the yellow removed on gate oil cylinder piston rod is protected
Sheath shuts gate 26, after shutting gate 26, it is ensured that gate clamping screw is locked, and in this step, the effect of control valve is to use
In control oil pressure, and then the open and-shut mode of regulating gate 26, gate oil cylinder drive the opening and closing of gate 26, lock under normal driving state
Door 26 is open, and part bolt, which is fallen, when to avoid driving state pounds gate piston rod, so early period can protect equipped with yellow
Sheath；
Step 7 is shown in Fig. 6, ball valve 1.1 is opened with 26 inside and outside differential pressure of balance gate, after inside and outside differential pressure balance, by ball
Valve 1.1 is shut, by locking mechanism controls at 2 grades；
Step 8 is shown in Fig. 7,4 two withdrawals completely of control oil cylinder；
Step 9, is shown in Fig. 8, removes connector 6, separates oil cylinder 4 with fixing seat, using second air hoist by oil cylinder
4 sling and are temporarily stored to a suitable position, are sure to that oil cylinder 4 and other weights are not placed on to the distachable platform of tool changing
On；
Step 10 is shown in Fig. 9, is fully drawn out and (pays attention to shake or swinging after knife cylinder 5 is extracted out) knife cylinder 5, and be transported to object
Expect transport channel；
Step 11, the cutter on more tool changing cylinder 5；
Step 12 carries out installation operation to the knife cylinder 5 after replacement cutter.
The installation of knife cylinder 5 is substantially the contrary operation that knife cylinder 5 is removed, but is the steps of and has to carry out in place: (1) knife
It,, must will be inside gate before knife cylinder 5 is put into gate valve body without jam plate is locked into 2 grades when cylinder 5 puts into gate valve body
(can contact) cleans out completely, and is smeared 5 outer surface of knife cylinder 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 Jia Shui, a ball valve 1.1 in the flushing pipeline on knife cylinder 5 need to be opened so that gas is arranged
Out；(4) when the space between knife cylinder 5 and gate 26, which fills its water of water, overflows from flushing ball valve 1, flushing pipeline ball is shut again
Valve；(5) when knife cylinder 5 being promoted gate valve body, notice that positioning pin consistent (must pay attention to location hole on gate valve body on knife cylinder 5
The position of positioning pin).
Locking mechanism is locked in 1 grade and 2 grades, wherein 1 grade and 2 grades is equivalent to two limiters, locking mechanism is locked in 1 grade
When oil cylinder 4 can only be recovered to a designated position, oil cylinder 4 can only be recovered to another specific bit when locking mechanism is scheduled on 2 grades
It sets.
Second of specific embodiment:
Step 1 is shown in Figure 10, controls area surface pressure, water pipe is connected with the flushing ball valve 10 on knife cylinder 14, opens punching
It washes ball valve 10 and rinses knife cylinder 14, closed after flushing and rinse ball valve 10 and remove water pipe, closed wear detection ball valve, then tear open
Except wear detection pipeline；
Step 2 is shown in Figure 11, and oil cylinder 12 is hung 14 position of knife cylinder using tool changing loop wheel machine, and oil cylinder 12 is fixed to knife cylinder 14
Lifting lug 11 on；
Step 3 is shown in Figure 12, and the pipeline of control valve and oil cylinder 12 is attached, and oil cylinder 12 is fully extended, uses 2
Pin locks oil cylinder 12 and stand 13, and the screw thread anchor ear of cylinder piston rod outer ring is unclamped；
Step 4 is shown in Figure 13 and Figure 14, and the piston rod band moving knife cylinder 14 for controlling oil cylinder 12 is retracted to 9 position of gate, by knife
Collet chuck tool is fixed on knife cylinder 14, air hoist suspension hook is hung on knife collet chuck tool, and hang power on air hoist band (just
Firmly), knife cylinder bracket 15 is fixed on 14 bottom of knife cylinder, at least uses the bolt of 3 M27；
Water pipe is connected in the flushing pipeline of gate 9 by step 5, opens the flushing ball valve 10 in flushing pipeline to rinse
Gate 9 after flushing, closes and rinses ball valve 10, and remove water pipe；
Step 6 is shown in Figure 15, and by the piping connection of control valve and gate 9, the yellow removed on gate oil cylinder piston rod is protected
