Exemplary embodiments that embody features and advantages of the utility model are described in detail below in the specification. It is to be understood that the utility model is capable of other embodiments and that various changes in form and details may be made therein without departing from the scope of the utility model and the description and drawings are to be regarded as illustrative in nature and not as restrictive.
The embodiment provides an offshore platform, which adopts a movable crane to meet the use of more service objects without arranging a plurality of cranes, tugboats and the like for auxiliary operation. The crane adopting the mode can rotate, stretch and move in a pitching mode by utilizing the original functions, and importantly, the crane can move through the walking guide rail to adjust the position according to the position of the target platform, so that the adaptability of the crane is improved, and more target platforms can be served.
Referring to fig. 1, fig. 1 shows a specific structure of an offshore platform 100 provided in this embodiment.
The offshore platform 100 is a semi-submersible platform, and comprises a platform body 11, support legs 12 arranged below the platform and a lower floating body 13 connected with the support legs 12. The floating action is mainly realized by the lower floating body 13, and the whole platform main body 11 is positioned above the sea level. The platform main body 11 has a main deck 111, and a living area and a working area on the main deck 111.
The crane 3 is movably arranged in the working area.
Specifically, a linear traveling rail 21 is laid on the main deck 111. The crane 3 includes a base 31 and a crane body 33 rotatably provided on the base 31. Wherein, the base 31 can be arranged on the walking guide rail 21 in a sliding way; the crane body 33 moves along the running guide rail 21 together with the base 31, and can adjust its own rotation angle to expand the hoisting operation range and serve production platforms at different positions.
In the present embodiment, the number of the travel rails 21 is at least two, and are arranged side by side, thereby supporting opposite sides of the crane base 31. Of course, multiple guide rail arrangements may be employed to improve the stability of the crane base 31. Further, the running rails 21 can be flexibly designed according to the deck space of the platform and the specific form of the platform to be served.
Referring to fig. 2, two anti-tilt rails 22 are disposed at positions corresponding to either one of the running rails 21.
The tilt prevention guide 22 is adapted to be brought into contact with the base 31, thereby preventing the base 31 from being tilted to the left or right during movement.
The two anti-tilt guide rails 22 are relatively protrudingly provided on the lateral left and right sides of the traveling guide rail 21, and the two anti-tilt guide rails 22 are symmetrically provided. The inclination prevention guide 22 is perpendicular to the running guide 21. Meanwhile, the anti-tilt guide rail 22 is a linear guide rail, and the extending direction of the anti-tilt guide rail 22 is the same as the extending direction of the traveling guide rail 21. Preferably, the anti-tilt guide rail 22 is integrally formed with the walking guide rail 21, and has the advantages of high strength and convenience in manufacturing and installation.
As shown in fig. 2, the base 31 includes a base 311 and two fixing bases 312 respectively disposed on both lateral sides of the base 311. The base 311 is slidably disposed on the upper surface of the traveling rail 21 via the roller 45, and the fixing base 312 extends vertically downward relative to the base 311. Thus, the cross-sectional shape of the base 31 is similar to an inverted U-shape. When the base 31 is assembled on the walking rail 21, the fixing seat 312 is parallel and opposite to the side wall of the walking rail 21 and is in sliding fit with the anti-tilt rail 22. In other embodiments, the shape of the base 31 can be flexibly designed according to the installation form of the base 31 of the crane 3, and the cross section can be various forms such as circular, square and the like.
The base 31 also comprises two symmetrically arranged anti-tilt bumps 34.
The inclination prevention protrusion 34 is protrudingly provided on an inner side of the fixing base 312 toward the side wall of the running rail 21. Preferably, the anti-tilt protrusion 34 is integrally formed with the fixing seat 312, and has high strength.
In the height direction, the anti-tilt protrusions 34 and the anti-tilt guide rails 22 are arranged in a staggered manner, and are mutually limited when the base 31 moves, so that the base 31 is prevented from being tilted, and the stability of the crane 3 is ensured.
Specifically, the anti-tip rail 22 is spaced above the anti-tip tab 34. In this embodiment, the anti-tip rail 22 is spaced a short distance from the anti-tip tab 34, which may range from 10mm to 30 mm.
At the same time, the projections of both the anti-tilt bump 34 and the anti-tilt rail 22 at the same horizontal plane largely coincide. This means that the anti-tilt rail 22 is closer to the inner side wall of the fixed seat 312 opposite to the anti-tilt rail 22, for example, the horizontal distance between the anti-tilt rail 22 and the inner side wall of the fixed seat 312 is 10mm to 30 mm. Meanwhile, the anti-tilt protrusion 34 is closer to the side wall of the walking rail 21 opposite thereto.
During the movement of the base 31 along the travel rail 21, the base 31 may be inclined to the left or right when the crane 3 rotates, which may affect the smooth movement of the base 31. At this time, under the action of the inclination, the fixing base 312 on one side below the base 31 is close to and abutted against the anti-inclination guide rail 22, and at the same time, the anti-inclination protrusion 34 protruding from the fixing base 312 on the other side is abutted against the side wall of the traveling guide rail 21, and the abutment generates a reaction force to limit the base 31 to continuously deviate, so that the base 31 is restored to the normal rail, and the moving straightness of the base 31 is ensured.
In this embodiment, the anti-tilt rail 22 is similar in shape to the anti-tilt tab 34, both of which are rectangular in cross-section.
As shown in fig. 2, the offshore platform 100 further includes a running gear. The position of the crane 3 can be changed by means of a movable running gear.
The walking device mainly comprises a motor 41, a speed changer 42, a rack 43, a gear 44, a roller 45 and a fixed pin 46.
Wherein, motor 41, derailleur 42 and gear 44 all locate on base 31, specifically, and motor 41 locates the eminence on base 311, and derailleur 42 is installed in the middle part of base 311. An output shaft of the motor 41 is connected to an input shaft of the transmission 42, and an output shaft of the transmission 42 is connected downward to the gear 44, so that the gear 44 is driven to rotate. The rack 43 extends on the side wall of the traveling rail 21, and the rack 43 is located above the anti-tilt rail 22. The rack 43 is intermeshed with the pinion 44. The roller 45 is connected with the bottom of the base 311, and the roller 45 runs on the running guide rail 21. The power direction of the motor 41 is changed by the transmission 42. The motor 41 drives the gear 44 to engage with the rack 43 to move, and the roller 45 rolls on the guide rail to complete the walking.
The lower part of the fixing seat 312 and the lower part of the traveling guide rail 21 are oppositely provided with pin holes which are penetrated through along the transverse direction, and the fixing pins 46 are penetrated through the pin holes to realize the limiting and fixing of the base 31. In addition, the traveling device further includes a control circuit for controlling the motor 41, and the base 31 and the traveling device are connected by upper and lower bolts.
During the moving process, the anti-tilting protrusion 34 and the anti-tilting guide rail 22 are mutually limited, so that the stability of the crane 3 is ensured.
After the crane base 31 is moved to the right position, the fixing pin 46 is used to transversely penetrate through the fixing seat 312 and the walking guide rail 21 for connection, the position of the crane base 31 is fixed, and meanwhile, the anti-tilt protrusion 34 and the anti-tilt guide rail 22 are matched to ensure the stability and reliability of the base 31.
In this way, the crane 3 can slide freely on the guide rail and stay at any desired position.
In conclusion, the offshore platform 100 of the present invention employs the movable crane base 31, can conveniently change the position of the crane 3, can change the work of the crane 3 from a fixed type to an adjustable type, and employs the anti-tilt guide rail 22 to achieve reliability of movement. The crane 3 can be flexibly applied to ocean platforms at various positions, so that the use objects of the crane 3 are enlarged, and the functional adaptability of the crane 3 is improved.
