Description

Substantial equipment is at the extraordinary mobile device at seabeach

The utility model relates to a kind of extraordinary mobile device, especially a kind of substantial equipment is at the extraordinary mobile device at seabeach.Belong to the flat-bottomed barge class field in the boats and ships.

In beach, utmost point neritic area, how to deliver substantial equipment, be the gordian technique of develop shoals, utmost point neritic area, be subjected to the great attention in offshore engineering field always.Multiple device and the technology developed all respectively have merits and faults as walking devices, air cushion vehicle technology, length apart from traction technology, trench digging and fill technology etc., and unique Applicable scope is respectively arranged.As walking devices, high to the load-carrying capacity requirement of soil property, involve great expense, but do not turn to function; The air cushion vehicle technology can only the little tonnage of carrying equipment, can not satisfy the requirement of pipe laying, cabling, drilling well, and dynamic air cushion is very big with air screw propelling power demand.In addition, long apart from the traction technology, if distance is long, frictional resistance is excessive, implements very difficulty.Through to existing publication and literature search, still find no the substantial equipment that can overcome above-mentioned shortcoming simultaneously extraordinary mobile device at the seabeach.

The purpose of this utility model is to overcome deficiency of the prior art and defective, and the extraordinary mobile device of a kind of substantial equipment at the seabeach is provided.

The technical solution of the utility model is as follows: the utility model is made up of hull, air chamber, ground tackle system and rigging system, hull is flat shape, its flat of bottom can contact with beach ground, and in flat bottoms the space of one indent being arranged is air chamber, and ground tackle system and rigging system all are arranged on the deck.Air chamber can also reduce the ground adsorption in the face of the contact pressure of hull, moving when being convenient to pull with reducing.

The ground tackle system comprises: by the huge anchor of special type, bar casts anchor, masthead guy rope and top lift winch cast anchor, the dead rope capstan winch, mast, the bar dead rope casts anchor, the dead rope winch, the dead rope leading sheave, the bar analog bracket is retouched in throwing, two bars that cast anchor can make box type construction, perhaps truss form, perhaps directly make with steel pipe, throwing is retouched bar and is connected with the deck with hinge at the bow of hull, casting anchor bar can be at dead rope, dead rope capstan winch and dead rope, leading sheave, in level, swing under the synergy of dead rope winch, about the capstan winch of two sides of a ship can be installed on the mast with screw, its height is with dead rope and cast anchor the point of connection of bar in same horizontal surface, when the bar that casts anchor is swung in horizontal surface, dead rope is all the time in same horizontal surface, one end of dead rope links to each other with the end of the bar that casts anchor, the other end is by being fixed on the leading sheave on the hull stern deck, enter and deck screw bonded assembly dead rope winch, one end of top lift links to each other with the end of the bar that casts anchor, the other end imports the top lift winch at the superstructure top that firmly is installed in hull, utilize top lift winch and top lift, the bar that casts anchor is swung in the vertical plane, bar is cast anchor in utilization can be in level, rotate around hinge-point in the vertical plane surface, the bar that casts anchor can be placed on the carriage fixingly, carriage is at the stern of hull and hull weld together securely.The rigging system comprises: compositions such as cat fall, four cylinder cat fall fairleads, hanger rope rope winch, windlass, extraordinary huge anchor links to each other with anchor cable by pulley, cat fall leads by pulley that is fixed on the boom end that casts anchor and the four cylinder fairleads that are fixed on the hull bow deck, enter winch, winch is screwed on the bow deck of hull, winch, fairlead, the cat fall anchor of can transferring and sling, windlass firmly is connected with the bow deck of hull with screw, and it is connected with anchor by anchor chain again.Utilize throwing to retouch lever system two anchors are thrown to desired locations such as ship the place ahead, side direction, after anchor penetrates top layer mud, utilize windlass to tighten up anchor chain, anchor fluke is nibbled soil layer under the people, produces big grasping force, forms the power that makes whole device move and turn to.If two anchor symmetries dish out, and tighten up simultaneously, can make the hull straight ahead, if not symmetry is dished out, or do not dish out simultaneously, or tighten up the length difference, hull is turned to.Cast anchor tighten up anchor chain-hull and advance-weigh anchor-cast anchor again ..., circulation is again and again intermittently advanced whole device.When whole device is not mobile, the bar that casts anchor can be utilized top lift winch, top lift dead rope and dead rope winch, bar be retouched in throwing be parked on the analog bracket, in deep water, can float, tug boat, or in deep water, berth.

Extraordinary huge anchor is made up of anchor shackle, anchor shank, rotation anchor fluke and bearing pin, extraordinary huge anchor has suitable people's soil area and weight ratio, can penetrate the mud top layer of load-carrying capacity difference, fall on the strong soil layer of bearing capacity, anchor fluke can only open to one-sided with respect to anchor shank, when anchor fluke and anchor shank close up, suitable initial angle is arranged.Closing up under the state, penetrating top layer mud with the least possible people's soil area, falling the strong soil layer of bearing capacity, after being subjected to the anchor chain pulling force, anchor fluke can open, and in the engaging-in reposefully soil layer, produces big grasping force.

The utlity model has significant effect and very strong practical value, be not only applicable to stronger beach of soil property load-carrying capacity and utmost point neritic area, and be applicable to the mud matter seabeach of load-carrying capacity difference; Not only have locomotive function, and have the function of turning to; Can deliver substantial equipment, can be used as the beach means of delivery of substantial equipment such as pipe laying, cabling, drilling well; The seabeach of little to the gradient, long distance utilizes this device, invest for a short time, implements simply.

Further describe below in conjunction with accompanying drawing:
