The upper planetary gear 303 different there are two height, for one of planetary gear 303 directly by big crossed helical gears 315, second is small
Crossed helical gears 316 drives feed screw 308, another planetary gear 303 passes through long planet wheel spindle 311, intermediate gear shaft 312
It changes and back-drives feed screw 308.When being achieved in collision planetary gear feeding from different directions, feed screw can be driven to conjunction
Suitable direction rotation, completes feeding, improves cutting efficiency.The height of two planetary gears 303 is different on three toolframes, cooperate into
To block, being able to achieve rotation every time has and only one planetary gear 303 is fed, and pacifies between planetary gear 303 and transmission shaft 317
Equipped with freewheel clutch 304, it is ensured that opposite direction rotation when planetary gear 303 will not opposite direction rotation, avoid withdrawing.Cutter
307 are mounted on cutter slide unit 305, drive cutter slide unit 305 to complete radial feed when feed screw 308 rotates.The row of cutter
It is also equipped with ROV handle 318 on star-wheel, after the completion of can cutting or manual withdrawing is completed by ROV when there is fortuitous event and is moved
Make.
3 tool feeding mechanisms 2 are spaced on 120 degree of fore-stocks 12 being mounted on forebay 10, and cutter can be made to close
Suitable position carries out the feeding in proper orientation.4 feeding block brackets being mounted on feeding block pedestal 201 constitute three layers of sky
Between.Feeding driving lever 203 is installed on different two layers in three sheaf spaces.Feeding block one shares 3, mutually constitutes adjacent two
In the 180 degree space of a feeding block composition, every layer of only feeding driving lever 203.The double layer design for cooperating toolframe, can make
When each toolframe passes through toolframe in any direction, all only one feeding driving lever 203 contact, avoid feed reversing with
Repeat feed.
Driving mechanism 4 is fixed on forebay 10 by slide rail 409, and drive motor 5 is turned by the driving of retarder 404
Disk 403 does rotary motion.Roller bearing 401 is mounted on turntable, is driven sine mechanism 402, is made the rack gear for being mounted on sine mechanism 402
412 do reciprocal linear motion.Rack gear 410 is engaged with pinion gear 411, so that pinion gear 411 does reciprocal rotary motion, and is had
There is sinusoidal nature.Pinion gear 411 constitutes gear speed increasing mechanism by speedup gear wheel 408, speedup pinion gear 406, so that driving
Gear 407 does the higher reciprocating rotating movement of revolving speed, so that and driving the traffic cycle 11 of the engagement of gear 407 to do stroke is 180 degree
And the reciprocating rotating with sinuso sine protractor moves.
Clamp system 9 is mounted between forebay 10 and rear frame 7.Clamp system is bilateral symmetry double layer design, left part
It is identical with right part, guarantee that its qualitative performance, double layer design guarantee its stability clamped, it is ensured that the axle center of fixture and pipeline
Axle center is overlapped.Fixing axle 901 secures fixtures between forebay 10 and rear frame 7, long clamping bar 902 and short clamping bar 906
Rotated around fixing axle.Long clamping bar 902 passes through the first drive rod 903 and drive rod 904 with short clamping bar 906 respectively
Connection.Two drive rods 903, long clamping bar 902 constitute parallelogram mechanism with short clamping bar 906 and work as folder due to its characteristic
When tight Driven by Hydraulic Cylinder drive rod 904 moves downward, angle that long clamping bar 902 rotates at any time with short clamping bar 906
It is all the same, and long clamping bar 902 and the angular bisector position of the angle of short clamping bar 906 are constant.Since its bilateral symmetry designs,
Four clamping bars of two sides can move synchronously, and can guarantee can make in the central axis and pipeline of pipeline at any time
Mandrel guarantees its performance of feeling relieved, improves cutting efficiency and cut quality to coinciding.Fixture also has mechanical interlock mechanism,
It is mounted on forebay 10 by pedestal 907.After clamping bar is completed to clamp, 911 rotary worm of ROV handle is operated by ROV
912, drive worm gear 913 to rotate.Worm gear 913 is connected with lead screw 908, and 908 both ends of lead screw are provided with oppositely oriented screw thread, works as silk
When thick stick 913 rotates, gripping block 909 and gripping block 910 are synchronously to intermediary movements.In left gripping block 909 and right gripping block 910
Inclined-plane is identical as the angle of 904 ramp of drive rod.When oblique on the inclined-plane and drive rod 904 in gripping block 909 and gripping block 910
When face is in contact, ROV stops operating.At this time due to screw thread and the latching characteristics of worm and gear, there is no the case where pretightning force
Under, left gripping block 909 with right gripping block 910 prevented also from drive rod 904 due to cutting when vibration and upward play, guarantee folder
Compaction forces.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
