Description
Technical field
The present invention relates to a kind of checkout gear of cutting for the deep water cutting.
Background technology
In the high-pressure abrasive material cutting operation, operating personnel manually control the cutting dolly around being cut by the operation of circle of contact cartridge type material under water.Because the cutting dolly moves under water, operating personnel can only be by virtue of experience, and the manual adjustments hydraulic flow is regulated control cutting trolley travelling, is cut fully for guaranteeing the cut material body, can only reduce cutting speed.After cutting finishes, need send the diver to go deep into underwater inspection cut material body and whether be cut fully, judge whether to mend and cut.Control accuracy is low, and cutting efficiency is low.
The key technology that the automatic control of cutter sweep under water relates to detects for cutting under water.The water cutter of cutting equipment is High-Pressure Water, for increase cutting effect a large amount of abrasive materials that mix in current, produces the current that splash in cutting process, directly threatens near other equipment of water cutter.In the cutting process, current can stir near the floating things such as sand and dust the cutting equipment, make water become muddy, and transparency descends.Influenced the cutting effect detection.Also to consider the equipment seal request under the deepwater environment in addition.
The proximity transducer technology maturation is widely used at present.Proximity transducer can detected object mobile message and have information, and be converted to the signal of telecommunication.Be adapted at using under the water environment, response speed is fast, and contact detection object not.Reliability height, life-span are long.
Summary of the invention
In order to realize the automatic control of deep water cutter sweep, the invention provides also a kind of easy for installation, good reliability, can satisfy the cutting checkout gear of underwater operation condition.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of checkout gear of cutting for deep water cutting comprises a proximity transducer 3, the 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 the cable outlet mouth, and bottom leaves slide bar 7 imports.The upper bracket 2 of sleeve pipe 6 inside and lower carriage 4 are divided into upper, middle and lower 3 sheaf spaces to sleeve pipe 6 inner spaces.Upper bracket 2 and lower carriage 4 are circular metal plate, and upper bracket 2 centers hollow out the signal that sends and receive for proximity transducer passage is provided, and the space is left at lower carriage 4 centers.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 objects.Proximity transducer 3 is fixed on the upper bracket 2, and spring 5 is fixed on the lower carriage 4.Slide bar 7 is made up of three parts, and top is the thin bar of cylindrical, massive, and the bottom is the cuboid bonding jumper, is welded on the circular metal plate upper and lower surface at slide bar middle part respectively, and the circular metal plate diameter is less than the internal surface of sleeve pipe diameter.Circular metal plate in the middle of the slide bar is positioned at the lower layer space of sleeve pipe 6 inside, and spring 5 is passed in the slide bar upper end, and the space by lower carriage 4 centers enters the inside pipe casing middle space, and spring 5 is clipped between the circular metal plate in the middle of lower carriage 4 and the slide bar 7.Slide bar 7 tops are positioned at the inside pipe casing middle space, as the detected object of proximity transducer 3.Slide bar 7 bottoms link together with the steamboat rotating shaft of advancing.The output signal of proximity transducer 3 is sent to control room on ground or the ship by watertight cable 1.
Sleeve pipe of the present invention, advance steamboat and slide bar material are the 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 is simple in structure.Can satisfy the deep water cutting environment well, and can judge effectively whether the cut material body is cut.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is working state figure of the present invention.
Among the figure: 1 watertight cable; 2 upper brackets; 3 proximity transducers; 4 lower carriages; 5 springs; 6 sleeve pipes; 7 slide bars; 8 steamboats of advancing; 9 cut material bodies; 10 fixed supports; 11 hydraulic giants.
The specific embodiment
Sleeve pipe 6 is fixed together by fixed support 10 and hydraulic giant 11.Hydraulic giant 11 is as the part of deep water cutter sweep, and is constant apart from the height on cut material body 9 surfaces.Proximity transducer is fixed on the upper bracket of sleeve pipe, and is also constant apart from the height on cut material body 9 surfaces.Slide bar 7 passes 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 the sleeve pipe, and the movement locus of the steamboat 8 that guaranteed to advance is consistent with cutting track.Spring 5 is fixed on the lower carriage 4, compresses the circular metal plate of slide bar 7 centres, and the steamboat that guaranteed to advance closely contacts with cut material body 9 surfaces.Circular metal plate diameter in the middle of the slide bar is slightly less than internal surface of sleeve pipe, can guarantee that slide bar can not break away from sleeve pipe, plays 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 the steamboat of advancing, and on the vertical direction of cut material surface, the variation of slide bar position is equal to the variation 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, proximity transducer 3 is converted to the signal of telecommunication with the position signalling of detected object, the signal of telecommunication is sent to control room on ground or the ship by watertight cable 1, has realized operating personnel on ground or ship judges whether the cut material body is cut.
