Refer to accompanying drawing 8-11, operation process and principle
The process of casting anchor
1. device connects
1) extension rod is bolted in spiral windlass mounting head, will leads an anchor hawser simultaneously and lie in anti-revolving on hanger;
2) extension rod loudspeaker casing pipe sleeve is being connected with on the mooring screw hex union of leading an anchor hawser;
3) guiding anchor hawser is through in guiding snap ring by clamp button of the spring, strains guide anchor cable after locking, finishing device connects.
2. spiral anchorage
1) testing fixture coupled condition errorless after, will be except spiral windlass other parts, as the integral body such as mooring screw, extension rod, anchor hawser are put into water, and mooring screw anchor head touches the bottom;
2) start spiral windlass and carry out anchorage operation, mooring screw is threaded to desired depth;
3) mooring screw in place after, spiral windlass, extension rod etc. are partly removed to receipts, the anchor hawser that is strained and fixed, completes vertical anchorage.
The process of weighing anchor
1. search is located
This process is divided into four steps
The first step, is through at by guiding snap ring the extension rod being connected on spiral windlass by guiding anchor hawser, and extension rod is glided to position (1) along guiding anchor hawser, and now under loudspeaker sleeve pipe, spacing ball is just touched on edge;
Second step, loudspeaker sleeve pipe is crossed spacing ball, and divides and lead an anchor hawser in the tension force effect bottom of guiding anchor hawser;
The 3rd step, under the guiding of leading two anchor hawsers triangular in shape of an anchor hawser is led position effect, loudspeaker sleeve pipe is drawn close to axis centre gradually, until under loudspeaker sleeve pipe along the hex union top that approaches spiral anchor rod, now hex union is in the ring of loudspeaker sleeve pipe in scope;
The 4th step, loudspeaker sleeve pipe continues descending, until inside pipe casing top is supported to hex union top, completes the sliding block joint of extension rod and spiral anchor rod;
2. rotation is weighed anchor
Extension rod and spiral anchor rod complete after sliding block joint, lax anchor hawser, and reverse starting spiral windlass is extracted mooring screw from subaqueous soil.
Principle of work
The utility model mainly solves two technical matterss that application mooring screw is carried out vertical anchorage waterborne: the one, and anchor pole orientation problem, the 2nd, anchor hawser rotational problems.
One, anchor pole orientation problem, the problem that will solve exactly while weighing anchor locking screw anchor how and extension rod is connected with spiral anchor rod.Mooring screw is arranged in deep water, is difficult to searched location.Address this problem and mainly taked following measures:
1) utilize anchor hawser as the slip rope with directional tagging, shaping-orientation snap ring makes extension rod slide to mooring screw along guiding anchor hawser, and makes the anchor hawser snap ring of can coming in and going out easily;
2) it is cylindrical adopting outside face, and inside face is the loudspeaker sleeve pipe of interior hexagonal cylinder, utilizes the tension force effect of guiding anchor hawser and leads the two-orbit effect of an anchor hawser, makes loudspeaker sleeve pipe be directed to smoothly and to locate;
3) spacing ball is set, prevents that extension rod loudspeaker sleeve pipe from missing the hex union of spiral anchor rod and causing connection failure.
Two, anchor hawser rotational problems, will solve the problem that rotates relatively freely of swivel and non-rotary body while casting anchor and weighing anchor operation exactly.Under friction force effect, mooring screw inevitably can drive together with the non-rotary bodies such as anchor hawser and rotate when extension rod rotates, and causes thus anchor hawser and extension rod tangle up, affects normally carrying out of operation.Address this problem and mainly taked following measures: the revolute between guiding snap ring and extension rod, anti-revolute of revolving between hanger and spiral anchor rod are designed to low friction pair, reduce the friction force between contact surface, make the to lead snap ring and anti-revolve hanger to remain on original place motionless of the restoring moment while simultaneously utilizing anchor hawser to be reversed as far as possible.
Refer to accompanying drawing 12, mooring screw vertical anchorage general arrangement waterborne
During vertical anchorage device work, under the rotary torque effect of spiral windlass, mooring screw, extension rod rotatablely move, and guiding anchor hawser, lead an anchor hawser, guiding snap ring, spacing ball, anti-ly revolve the not rotations thereupon such as hanger, will substantially keep quiescence.
The above, be only preferred embodiment of the present utility model, not structure of the present utility model done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of the technical solution of the utility model.
