Description

Turret type single-point assembly guiding device

Technical Field

The invention relates to the field of single-point mooring for offshore crude oil or product oil transmission, in particular to a guide device capable of guiding a buoy in a single-point mooring device to be in butt joint with a turret.

Background

Offshore oil is increasingly gaining attention as a major source of crude oil. The transfer of crude or product oil typically takes two forms: the production platform or the FPSO is conveyed to the shuttle tanker through the single-point mooring device; the shuttle tanker is used as a port on the sea surface through a single-point mooring device to realize oil transportation with a land factory.

The single-point mooring device is divided into a turret type single point and a turret type single point. Compared with the turret type single point, the turret type single point has the characteristics of long service life and good stability.

The construction of a turret type single point mooring is particularly important. The turret type single point mooring device consists of a buoy and a turret, wherein the buoy provides buoyancy and serves as a rotating part, and the turret serves as a mooring fixing part.

Although the turret type single-point mooring device has the advantages and characteristics, the difficulty in building is relatively high. As the radial clearance between the outer upright column phi 4012mm of the turret and the inner barrel phi 4022mm of the buoy is small, the height is about 4500mm, the weight of the buoy is 140 tons, the buoy is assembled with the turret by hoisting by a crane, and the radial assembly clearance is only 10mm, so that great difficulty is brought to accurate and safe installation.

Disclosure of Invention

In order to solve the problems, the invention provides a turret type single-point assembly guide device, which adopts the technical scheme that:

the utility model provides a turret type single-point assembly guider, has capstan head and flotation pontoon, the flotation pontoon cup joints outside the capstan head stand, has the guider body, the whole "C" style of calligraphy that is of direction body, the top and the bottom of direction body are square plate, the "C" style of calligraphy opening of direction body towards the capstan head stand, the direction body top is fixed the flotation pontoon bottom, the square plate at direction body top with the flotation pontoon bottom aligns, direction body bottom is fixed with the gyro wheel, the gyro wheel passes through the round pin axle to be fixed direction body bottom, the gyro wheel with the surface of capstan head stand contacts, the baffle passes the round hole that round pin axle one end has, the baffle passes through the bolt fastening on the direction body. The baffle plays the fixed action to the axis of rotation, prevents that the gyro wheel from rotating the in-process, and the axis of rotation also follows the gyro wheel and rotates.

Above-mentioned turret type single point assembly guider, further, the gyro wheel imbeds the square board center in direction body bottom, through the round pin axle is fixed.

Above-mentioned turret type single point assembly guider, further, the baffle is the rectangle, the baffle passes the round hole that round pin axle one end was equipped with, the baffle both ends pass through the bolt fastening on the direction body.

Above-mentioned turret type single point assembly guider, further, the square board length of direction body bottom is greater than the square board length at direction body top.

Above-mentioned turret type single point assembly guider, further, the direction body passes through the bolt fastening in the flotation pontoon bottom, the bolt passes in proper order the flotation pontoon, the direction body, with the nut cooperation.

In the turret-type single-point assembling guide device, furthermore, the number of the bolts is two, and the two bolts are arranged side by side.

When the device is used, two or more than two guide devices are required to be used simultaneously, the guide devices are fixed at the bottom of the buoy, and the buoy can be safely and reliably assembled on the turret upright post through the guide of the rollers, so that the buoy can be smoothly installed in place. When the roller wheels are used, the roller wheels not only play a role in guiding the buoy, but also are stressed in the downward process of the buoy, the roller wheels are mutually restricted, the turret upright post is positioned at the center of the buoy, and even if the gap between the turret upright post and the buoy is small, the safe falling of the buoy can be ensured.

FIG. 2 is a schematic side view of the present invention;

FIG. 3 is a schematic view of the installation of the buoy and turret column;

wherein: 1-turret column, 2-buoy, 5-guide device, 5.1-guide body, 5.2-roller, 5.3-bolt, 5.4-pin shaft and 5.5-baffle.

Detailed Description

The invention is further explained with reference to the drawings.

A buoy 2 of a turret type single-point mooring device needs to be sleeved outside a turret upright post 1, and 4 turret type single-point assembly guide devices (hereinafter referred to as guide devices) are fixed at the bottom of the buoy at equal intervals along the circumferential direction of the buoy.

The guiding device is provided with a guiding body 5.1, the guiding body is integrally in a C shape, the C-shaped opening of the guiding body faces to the turret upright post, the top and the bottom of the guiding body are square plates, the square plate at the top of the guiding body is aligned with the bottom of the floating barrel, as shown in figures 1 and 2, the guiding body is fixed at the bottom of the floating barrel through a bolt 5.3, a roller 5.2 is fixed at the bottom of the guiding body and is located at the center of the square plate at the bottom of the guiding body, the roller is fixed at the bottom of the guiding body through a pin shaft 5.4, and the roller is in contact with the outer surface of the turret upright post. After the pin shaft penetrates through the guide body and the idler wheel, the pin shaft is fixed through the baffle, the baffle penetrates through a round hole formed in one end of the pin shaft, two ends of the pin shaft are fixed to the guide body through bolts, and when the idler wheel is prevented from rotating, the pin shaft is also rotated accordingly.

The invention has simple structure, and the guide device is arranged at the bottom of the buoy, so that the buoy can be safely and reliably assembled on the turret upright post, and the buoy can be smoothly arranged in place.
