Abstract
The utility model relates to a hydraulic elevator for an offshore floating device, which is characterized in that the hydraulic elevator comprises a hydraulic system, elevating cylinders, a clamping system, a positioning and fixing system, pillars, a frame, a guide pipe and the offshore floating device; the hydraulic elevator for the offshore floating device is used in combination with the offshore floating device and the pillars; the hydraulic system and the elevating cylinders are arranged on the offshore floating device; the offshore floating device is fixedly connected to the pillars through the clamping system and the positioning and fixing system arranged on the elevating cylinders; based on the design for the load capacity of the pillars, two to eight elevating cylinders are arranged on each pillar; and the number of either the pillars or hydraulic elevating units on each offshore floating device is no less than three, and the pillars and the hydraulic elevating units are arranged in the shape of triangle, circle or square on a deck of the offshore floating device. The hydraulic elevator for the offshore floating device provided by the utility model has the characteristics of large elevating tonnage, high safety factor, simple structure and relatively low cost.
Description
Technical field
The utility model belongs to a kind of hydraulic lift, particularly a kind of marine surface unit hydraulic hoist.
Background technology
At present, at sea on the marine surface unit such as platform, most electric gear tooth bar lifting mechanism and the steel rope capstan winch lifting mechanisms of adopting of the jacking system that is adopted, preceding a kind of lifting mechanism exists: complex structure, investment cost height; A kind of lifting mechanism in back exists: problems such as the lifting tonnage is less, and safety factor is lower.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is to be marine surface units such as offshore platform, provides a kind of and has that the lifting tonnage is big, safety factor is high, simple in structure, marine surface unit hydraulic hoist that cost is relatively low.
The marine surface unit hydraulic hoist of the utility model content Description:
The marine surface unit hydraulic hoist of the utility model, it is characterized in that: it comprises hydraulic efficiency pressure system, hoist cylinder, clamping system, positioning and fixing system, pillar, framework, guide pipe and marine surface unit, marine surface unit hydraulic hoist and marine surface unit and a column kit use, at sea surface unit is provided with hydraulic efficiency pressure system and hoist cylinder, by clamping system and the positioning and fixing system that is provided with on the hoist cylinder marine surface unit is fixedly connected on the pillar;
Load capacity design according to pillar is provided with 2～8 hoist cylinders on every pillar;
On every Taiwan Straits surface unit upper supporting column and hydraulic lifting unit quantity be no less than 3 the cover, at sea on the surface unit deck with triangle or circle or square arrangement.
The marine surface unit hydraulic hoist of the utility model has that the lifting tonnage is big, safety factor is high, simple in structure, characteristics that cost is relatively low.
Description of drawings
Fig. 1 is marine surface unit hydraulic hoist structural representation
Among the figure: the 1st, hydraulic efficiency pressure system, the 2nd, hoist cylinder, the 3rd, clamping system, the 4th, positioning and fixing system, the 5th, pillar, the 6th, framework, the 7th, guide pipe, the 8th, marine surface unit, the 9th, the water surface, the 10th, seabed.
The specific embodiment
The marine surface unit hydraulic hoist of the utility model is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, marine surface unit hydraulic hoist, it comprises: hydraulic efficiency pressure system 1, hoist cylinder 2, clamping system 3, positioning and fixing system 4, pillar 5, framework 6, guide pipe 7 and marine surface unit 8, marine surface unit hydraulic hoist and marine surface unit 8 and pillar 5 supporting uses, at sea surface unit 8 is provided with hydraulic efficiency pressure system 1 and hoist cylinder 2, by clamping system 3 and the positioning and fixing system 4 that is provided with on the hoist cylinder 2 marine surface unit 8 is fixedly connected on the pillar 5.Weight and operating characteristic according to marine surface unit are determined pillar quantity, design oil cylinder tonnage, quantity and stroke.
The load by factor of natural environment such as wind, wave, stream, tide, earthquakes should will be considered simultaneously according to marine surface unit 8 distribution of load reasonable Arrangement in the position of pillar 5 and hydraulic hoist.It is to provide hydraulic power by hydraulic efficiency pressure system 1, by control system hydraulic power is offered hoist cylinder 2 and clamping system 3, under the clamping of hoist cylinder 2 and clamping system 3 and fixed system 4 and pillar 5, lifting, fixing working in reciprocating mode, marine surface unit 8 is promoted or drop to the height that needs by framework 6 and guide pipe 7.
Marine surface unit hydraulic hoist is matching used with the surface unit pillar, can 2～8 hoist cylinders be set according to every pillar load capacity, determines hoist cylinder diameter and stroke by marine surface unit constructional feature simultaneously.Add the non-return lock on the hydraulic efficiency pressure system, make hoist cylinder and clamping oil cylinder reliable operation.
The screw thread that satisfies design load, positioning groove, knock hole or location tooth bar to be arranged on clamp fitting system and the pillar, make clamping system, fixed system supporting, guarantee the safe in utilization of marine surface unit with it.
Form elevator group by the above elevator of three covers, to guarantee the stable of marine surface unit, again according to the weight of marine surface unit and the quantity of volume and operating characteristic increase pillar and elevator.
The hydraulic lifting unit of at sea installing on the surface unit, by hydraulic hoist surface units such as offshore work platform, life afloat, lodging, amusement are inserted into seabed 10 by pillar after, rise to the altitude hold that the water surface needs more than 9.
When marine surface unit need be changed the place of erection, marine surface unit hydraulic hoist can drop to marine surface unit in the water, and pillar is recovered in the marine surface unit after promoting, and does not influence marine surface unit and navigates by water in water.
