Description
Technical field
The present invention relates to a kind of for deep water cutting cut checkout gear.
Background technology
Under water in high-pressure abrasive material cutting operation, operating personnel's Non-follow control Cutting dolly cuts around being run by circle of contact cartridge type material.Because Cutting dolly runs under water, operating personnel can only by virtue of experience, and manual adjustments hydraulic flow regulable control Cutting dolly runs, and for guaranteeing that cut material body is cut completely, can only reduce cutting speed.After cutting, need to send diver to go deep into underwater inspection cut material body and whether cut completely, judge whether that carrying out benefit cuts.Control accuracy is low, and cutting efficiency is low.
The key technology that the automatic control of imderwater cutting device relates to is that imderwater cutting detects.The water cutter of cutting equipment is High-Pressure Water, to adulterate a large amount of abrasive material, producing splashing current in cutting process for increasing cutting effect in current, other equipment directly near threat water cutter.In cutting process, current can stir the floating things such as the sand and dust near cutting equipment, and make water become muddy, transparency declines.Have impact on cutting effect to detect.Also to consider the equipment seal request under deepwater environment in addition.
Current proximity transducer technology maturation, is widely used.The mobile message of proximity transducer energy detected object and there is information, and be converted to the signal of telecommunication.Use under being adapted at water environment, fast response time, and not contact detection object.Reliability is high, the life-span is long.
Summary of the invention
In order to realize the automatic control of deep water cutter sweep, the invention provides the cutting checkout gear that also a kind of easy for installation, reliability is strong, can meet underwater operation condition.
To achieve these goals, technical scheme of the present invention is as follows:
For deep water cutting cut a checkout gear, comprise a proximity transducer 3, steamboat 8 of advancing, slide bar 7, spring 5, sleeve pipe 6 and upper bracket 2, lower carriage 4.Sleeve pipe 6 is hollow cylinder, and top cover leaves cable outlet mouth, and bottom leaves slide bar 7 import.The upper bracket 2 of sleeve pipe 6 inside and lower carriage 4 are divided into upper, middle and lower 3 sheaf space sleeve pipe 6 inner space.Upper bracket 2 and lower carriage 4 are circular metal plate, and the signal that upper bracket 2 center hollows out as proximity transducer transmission and reception provides passage, and space is left at lower carriage 4 center.The upper strata space mounting proximity transducer 3 of sleeve pipe 6 inside, lower layer space mounting spring 5, middle space is as the activity space of proximity transducer 3 detected object.Proximity transducer 3 is fixed on upper bracket 2, and spring 5 is fixed on lower carriage 4.Slide bar 7 is made up of three parts, and top is cylindrical, massive thin bar, and bottom is cuboid bonding jumper, and be welded on the circular metal plate upper and lower surface in the middle part of slide bar respectively, circular metal plate diameter is less than internal surface of sleeve pipe diameter.Circular metal plate in the middle of slide bar is positioned at the lower layer space of sleeve pipe 6 inside, and slide bar upper end, through spring 5, enters inside pipe casing middle space by the space at lower carriage 4 center, and spring 5 is clipped between the circular metal plate in the middle of lower carriage 4 and slide bar 7.Slide bar 7 top is positioned at inside pipe casing middle space, as the detected object of proximity transducer 3.Link together with steamboat rotating shaft of advancing bottom slide bar 7.The output signal of proximity transducer 3 is sent to the control room on ground or ship by watertight cable 1.
Slide bar 7 to have passed through bottom sleeve pipe 6 and lower carriage 4, when sleeve position is fixed, ensure that advance steamboat and slide bar do not have the movement of horizontal level, and the steamboat driving trace that can make like this to advance is consistent with cutting track.Circular metal plate in the middle of slide bar 7 ensure that slide bar 7 and steamboat 8 of advancing can not depart from sleeve pipe, and spring 5 ensure that advance dolly and cut material surface close contact.When little rolling of advancing crosses cutting track, it is consistent that joint-cutting change in depth changes with the distance of top end of sliding rod distance proximity transducer.The positional information that proximity transducer detects is joint-cutting depth information, and this information can as the foundation judging whether to cut.
Sleeve pipe of the present invention, advance steamboat and slide bar material are antifriction metal (AFM) alloy.
The insulation sheath of watertight cable of the present invention is corrosion-resistant material.
The present invention adopts proximity transducer to detect Cutting dolly underwater operation state, and structure is simple.Deep water cutting environment can be met well, and effectively can judge whether cut material body is cut.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is working state figure of the present invention.
In figure: 1 watertight cable; 2 upper brackets; 3 proximity transducers; 4 lower carriages; 5 springs; 6 sleeve pipes; 7 slide bars; 8 advance steamboat; 9 cut material bodies; 10 fixed supports; 11 hydraulic giants.
Detailed description of the invention
Sleeve pipe 6 is fixed together by fixed support 10 and hydraulic giant 11.Hydraulic giant 11 is as a part for deep water cutter sweep, and the height on distance cut material body 9 surface is constant.Proximity transducer is fixed on the upper bracket of sleeve pipe, and the height on distance cut material body 9 surface is also constant.Slide bar 7 is through sleeve bottom and lower carriage 4, and internal surface of sleeve pipe also has supporting role to the circular metal plate in the middle of sleeve pipe, ensure that the movement locus of steamboat 8 of advancing is consistent with cutting track.Spring 5 is fixed on lower carriage 4, compresses the circular metal plate in the middle of slide bar 7, ensure that advance steamboat and cut material body 9 intimate surface contact.Circular metal plate diameter in the middle of slide bar is slightly less than internal surface of sleeve pipe, can ensure that slide bar can not depart from sleeve pipe, play clamping action to slide bar.The top of slide bar 7 is as the detected object of proximity transducer 3.Slide bar is synchronized with the movement with steamboat of advancing, and in the vertical direction of cut material surface, the change of slide bar position is equal to the change of the joint-cutting degree of depth.Like this, the position signalling of detected object just can reflect the depth of cut of cut material body, the position signalling of detected object is converted to the signal of telecommunication by proximity transducer 3, the signal of telecommunication is sent to the control room on ground or ship by watertight cable 1, achieves operating personnel on ground or ship, judges whether cut material body is cut.
