Description

FPSO module major diameter oil gas pipeline hoisting machine constructs

Technical Field

The utility model relates to a crane structure of ocean engineering is served FPSO module major diameter oil gas pipeline hoisting machine very much and is constructed.

Background

In the ocean engineering FPSO construction process, the large-diameter oil-gas pipeline needs to be welded in advance and then installed in a hoisting mode. In the installation of FPSO module major diameter oil gas pipeline, the method that often adopts is that the mode that adopts the hoist to carry out combined hoisting is gone on, the mode that this kind of hoist combined hoisting needs to go on in step, can not receive weather environment's such as wind, rain influence at the hoist and mount in-process, and at the in-process of hoist and mount, the mode that constructor adopted usually is tied up with wire rope, then adopt the hoist to hoist and mount again, this kind of mode of tying up produces major diameter pipeline landing, phenomenons such as unhook very easily at the hoist and mount in-process, can cause serious hoist and mount accident under the serious condition. Therefore, the utility model provides a FPSO major diameter oil gas pipeline hoisting machine constructs.

Disclosure of Invention

An object of the utility model is to overcome prior art's is not enough, provide a hoisting machine who serves FPSO module major diameter oil gas pipeline constructs. When the large-diameter pipeline of the FPSO module is hoisted, the problems of pipeline slipping, unhooking and the like caused by external influence during hoisting of the large-diameter pipeline in the hoisting process are solved, and hoisting accidents are reduced, so that the hoisting requirement on the large-diameter pipeline is met.

In order to achieve the above object, the utility model adopts the following technical scheme:

FPSO module major diameter oil gas pipeline hoisting machine construct, including installing the pipeline gallows in the oil gas pipeline left and right sides respectively, each the pipeline gallows include the last roof that sets up along the horizontal direction, four connecting plate roofs that set up along vertical direction are fixed respectively around last roof on the diapire of border position department about both sides, it has the guide way to open along vertical direction on each connecting plate, be fixed with an hydro-cylinder respectively in the left and right sides of last roof, the telescopic link of each hydro-cylinder passes the roof and the tip passes through the nut and links to each other with last grip block is fixed along vertical direction, it has a guide post that sets up along the horizontal direction to weld respectively in both sides around last grip block, two guide posts are inserted respectively and are corresponded the guide way of the connecting plate that sets up around and can be followed the guide way and slide from top to bottom. The top wall of a lower clamping plate is fixedly connected with the bottom walls of the four connecting plates respectively.

The utility model has the advantages that:

the utility model discloses a hydraulic pressure centre gripping scheme has solved the FPSO module major diameter oil gas pipeline hoist and mount in-process and has received the influence of environmental factor, solves phenomenons such as the easy landing of major diameter pipeline, easy unhook among the hoist and mount process, the utility model discloses the suitability is high, the laminating degree is high, is difficult for droing, has guaranteed the security performance of major diameter oil gas pipeline hoist and mount process, improves hoist and mount efficiency.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in the attached drawings, the FPSO module major diameter oil gas pipeline hoisting mechanism comprises pipeline hangers 2 respectively arranged at the left and right sides of a major diameter oil gas pipeline 1.

Each pipeline hanger 2 comprises an upper top plate 2-1 arranged in the horizontal direction, top walls of four connecting plates 2-2 arranged in the vertical direction are respectively fixed on bottom walls at the left and right edge positions of the front and back sides of the upper top plate 2-1, a guide groove is formed in each connecting plate 2-2 in the vertical direction, oil cylinders 2-3 are respectively fixed on the left and right sides of the upper top plate 2-1, a telescopic rod of each oil cylinder 2-3 penetrates through the upper top plate 2-1 in the vertical direction, the end part of each oil cylinder is fixedly connected with an upper clamping plate 2-4 through nuts 2-5, guide columns 2-7 arranged in the horizontal direction are respectively welded on the front and back sides of the upper clamping plate 2-4, and the two guide columns 2-7 are respectively inserted into the guide grooves of the connecting plates 2-2 correspondingly arranged in the front and back directions and can slide up and down along the guide grooves. The top wall of one lower clamping plate 2-8 is fixedly connected with the bottom walls of the four connecting plates 2-2 respectively.

Rubber layers 2-6 are respectively bonded on the bottom wall of the upper clamping plate 2-4 and the top wall of the lower clamping plate 2-8.

Two lifting lugs 2-9 are respectively fixed at the left and right ends of the front and rear sides of the top wall of the upper top plate 2-1 of each pipeline hanger 2, and the two lifting lugs 2-9 at the front side and the two lifting lugs at the rear side are respectively connected to a lifting ring 4 of a crane through steel strands 3.

Preferably, the upper clamping plate 2-4 and the lower clamping plate 2-8 are in a V-shaped structure.

The specific working principle is as follows:

retracting telescopic rods of oil cylinders 2-3 of a pipeline hanger 2, respectively installing the pipeline hanger 2 on the left side and the right side of a large-diameter oil-gas pipeline 1, wherein the bottom end of a steel strand 3 is tied and fixed on lifting lugs 2-9 of the pipeline hanger 2, the top of the steel strand is tied and fixed on a lifting ring 4, and the lifting ring 4 is installed on a lifting hook of a crane. After the installation is finished, the telescopic rods of the oil cylinders 2-3 of the pipeline hanging bracket 2 are extended out, the large-diameter oil-gas pipeline 1 is clamped on the lower clamping plates 2-8 through the upper clamping plates 2-4, after the clamping is finished, a hoisting worker operates a crane to hoist the large-diameter oil-gas pipeline 1 to the installation position, after the hoisting is finished, the telescopic rods of the oil cylinders 2-3 of the pipeline hanging bracket 2 are retracted, the pipeline hanging bracket 2 is detached, and next hoisting preparation is carried out.
