Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, specifically to a crane support cylinder for a crane ship. Background Technology

[0002] In the current technology, with the rapid development of the world economy, the demand for traditional energy sources such as oil and natural gas is increasing year by year, while the production of land resources can no longer meet the growing needs. Countries have begun to vigorously develop offshore oil exploration and exploitation. As an auxiliary barge for marine engineering, crane ships play an important role in the development of offshore oil and gas fields. In addition, large crane ships are also indispensable equipment for offshore engineering hoisting, dismantling (platforms, large parts, structures) and marine salvage operations. As a key device of crane ships, the crane support cylinder supports the entire crane and the forces it bears during operation, providing theoretical support and technical guarantee for the safe and stable operation of crane ships.

[0003] In the prior art, the support cylinder structure of cranes is as follows: Patent document CN 103663133 A discloses "a marine crane base". This technical solution includes a base, with an upper flange and a lower flange respectively provided on the upper and lower parts of the base. The upper flange is connected to the slewing bearing by fasteners. It also includes a base, with reinforcing ribs installed on the outer circumference of the base. An upper flange is provided on the upper part of the base, which is connected to the lower flange of the base by bolts. Reinforcing plates are provided on the upper and lower parts of the outer circumference of the base.

[0004] The main advantages of the above technical solution are its compact and reasonable structure; convenient manufacturing, installation, and disassembly, avoiding the cumbersome operation of cutting the base during maintenance as required in existing technologies. In this solution, the base is connected to the base with bolts. When maintenance or replacement of the marine crane base is needed, only the bolts connecting the lower flange of the base and the upper flange of the base need to be removed, eliminating the need for cutting. It offers advantages such as flexible and convenient installation and disassembly, strong usability, and improved work efficiency.

[0005] However, in the above technical solutions, the base is only supported and fixed by reinforcing plates, bases, etc., and the support function and stability are very general, which cannot provide strong support for cranes.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a crane support cylinder for crane ships with very high stability and support capacity. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a crane support cylinder for a crane vessel; the technical solution is as follows:

[0008] A crane support cylinder for a crane vessel includes a base on which a support cylinder is mounted. The upper end of the support cylinder is provided with an outwardly extending support portion. A fixed flange is correspondingly mounted on the upper end of the support portion. The fixed flange is correspondingly mounted with a slewing bearing mechanism of the crane, and the slewing bearing mechanism extends into the support cylinder. The lower end face of the support portion is also provided with a ring of inclined support surface.

[0009] Several support ribs are also provided on the outer wall of the support cylinder. The support ribs extend upward from the base at the bottom and are fixed to the inclined support surface of the support part. A detachable support sealing plate is also installed at the end position of two adjacent support ribs. The support sealing plate forms a closed area between the two support ribs. In this closed area, staggered support ribs are installed on the outer wall of the support cylinder and the inner wall of the support sealing plate. Concrete is poured into this closed area to completely fill it. The cooled concrete supports the support part above.

[0010] Furthermore, a total of ten supporting stiffeners are provided on the support cylinder, with the ten supporting stiffeners evenly spaced, while five supporting sealing plates and closed areas are provided accordingly, with the five closed areas evenly spaced.

[0011] Furthermore, a triangular support is provided between two adjacent enclosed areas on the outer side of the support cylinder. Five triangular supports are provided in total, and the triangular supports are installed on the outer wall of the support cylinder and the bottom is installed on the base to support the entire support cylinder at an angle.

[0012] Furthermore, mounting holes are provided at the ends of the supporting stiffener and at both ends of the supporting sealing plate, and fasteners are installed in the mounting holes, allowing the supporting sealing plate to be detached and installed.

[0013] Furthermore, the support portion includes an upper horizontal end and a lower inclined end. The fixed flange is installed on the horizontal end, and the inclined end is provided with an inclined support surface, the inclination angle of which is set to 45°.

[0014] Furthermore, the base is also provided with an installation component, which secures the base to the crane vessel.

[0015] Beneficial effects: The present invention has the following beneficial effects:

[0016] (1) The crane of the present invention still relies on the overall base and support cylinder for support. However, the present invention provides a support part at the upper end of the base. The specific shape and structure of the support part is configured such that the upper side is a horizontal end and the lower side is an inclined end. The horizontal end is used to install a fixed flange, which is used to install a slewing bearing mechanism. The inclined end at the lower side is provided with a ring of inclined support surface, which is used to support the installation of stiffeners. The entire crane can be supported by the support cylinder, which is also more reasonable in terms of structure.

[0017] (2) The most important aspect of this invention is the provision of support stiffeners on the side wall of the support cylinder. There are many support stiffeners. On the one hand, the support stiffeners are used to increase the support force of the support cylinder. On the other hand, adjacent support stiffeners can form a closed area. The outside of the closed area is then sealed by a support sealing plate. Concrete is then injected into the closed area. The support stiffeners extend upward from the base plate at the lower end to the inclined support surface. The concrete is injected until the entire closed area is filled. After the concrete solidifies, several concrete support columns are formed on the outer side wall of the support cylinder. In addition, with the support of the support stiffeners and the support sealing plate, the upper outward support part can be supported. The stability and support performance of the overall structure are greatly improved.

[0018] (3) In this invention, both the supporting stiffener plate and the support cylinder are equipped with supporting stiffeners. The performance of the concrete is increased by the cooperation of the supporting stiffeners with the poured concrete. In addition, the location of the closed area is specifically set in this invention. There are a total of ten supporting stiffener plates in this invention, which constitute five closed areas. The closed areas are set at intervals, so a part of the area is left empty at the interval of the closed areas. In this invention, a triangular support is set in the empty area. The side wall of the triangular support is installed on the side wall of the support cylinder and the bottom is fixed on the base, thereby supporting the entire support cylinder. In conjunction with the concrete support columns on both sides, the stability and stability are further increased.

[0019] (4) In this invention, the support sealing plate on the support rib is detachable and can be installed. In order to adapt to the concrete pouring diagram, a pouring hole can be set at the upper end of the support sealing plate. The interior can be completely filled through the pouring hole. At the same time, the installation components are set on the base, which can be installed more stably on the crane ship. Attached Figure Description

[0021] Figure 2 for Figure 1 Sectional view of AA. Detailed Implementation

[0022] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0023] like Figure 1 and Figure 2 As shown, a crane support cylinder for a crane ship includes a base 1, on which a support cylinder 2 is mounted. The upper end of the support cylinder 2 is provided with an outwardly extending support portion 3. The upper end of the support portion 3 is correspondingly provided with a fixed flange 4, which is correspondingly installed with the slewing bearing mechanism of the crane. The slewing bearing mechanism extends and is installed inside the support cylinder 2. The lower end face of the support portion 3 is also provided with a ring of inclined support surface 5.

[0024] The support part 3 includes an upper horizontal end 31 and a lower inclined end 32. The fixed flange 4 is installed on the horizontal end 31. The inclined end 32 is provided with an inclined support surface 5, and the inclination angle of the inclined support surface 5 is set to 45°.

[0025] The crane of the present invention still relies on the overall base and support cylinder for support. However, the present invention provides a support part at the upper end of the base. The specific shape and structure of the support part is configured such that the upper side is horizontal and the lower side is inclined. The horizontal end is used to install the fixing flange, which is used to install the slewing bearing mechanism. The inclined support surface is provided on the lower inclined end, which is used to support the installation of the stiffening plate. The entire crane can be supported by the support cylinder, which is also relatively reasonable in structure.

[0026] Several support ribs 6 are also provided on the outer wall of the support cylinder 2. The support ribs 6 extend upward from the base 1 at the bottom and are fixed to the inclined support surface 5 of the support part 3. A detachable support sealing plate 7 is also installed at the end position of two adjacent support ribs 6. The support sealing plate 7 forms a closed area 8 between the two support ribs 6. In the closed area 8, staggered support ribs 9 are installed on the outer wall of the support cylinder 2 and the inner wall of the support sealing plate 7. Concrete 16 is poured into the closed area 8 to completely fill the closed area 8. The cooled concrete 16 supports the support part 3 above.

[0027] The most important aspect of this invention is the provision of supporting stiffeners on the sidewalls of the support cylinder. Multiple supporting stiffeners are provided, serving two purposes: firstly, to increase the supporting force of the support cylinder; and secondly, to create a closed area between adjacent supporting stiffeners. This closed area is then sealed off by a supporting sealing plate. Concrete is then injected into this closed area, with the supporting stiffeners extending upwards from the lower base plate to the inclined supporting surface. The concrete fills the entire closed area. After the concrete solidifies, several concrete supporting columns are formed on the outer sidewalls of the support cylinder. Combined with the support stiffeners and the supporting sealing plate, this supports the outwardly expanding upper support section, significantly improving the overall structural stability and supporting performance.

[0028] Ten support ribs 6 are provided on the support cylinder 2. The ten support ribs 6 are evenly spaced, while five support sealing plates 7 and five closed areas 8 are provided. The five closed areas 8 are evenly spaced.

[0029] A triangular support 11 is also provided between two adjacent closed areas 8 on the outer side of the support cylinder 2. Five triangular supports 11 are provided, and the triangular supports 11 are installed on the outer wall of the support cylinder 2 and the bottom is installed on the base 1, which obliquely supports the entire support cylinder 2.

[0030] In this invention, both the supporting stiffeners and the support cylinder are equipped with supporting ribs. The performance of the concrete is enhanced by the cooperation of the supporting ribs with the poured concrete. In addition, the invention also specifically sets the location of the closed areas. The invention has a total of ten supporting stiffeners, forming five closed areas. The closed areas are spaced apart, leaving a portion of the area empty. In this empty area, the invention sets a triangular support. The sidewall of the triangular support is installed on the sidewall of the support cylinder, and the bottom is fixed to the base, thereby supporting the entire support cylinder. Together with the concrete support columns on both sides, the stability and sturdiness are further increased.

[0031] Mounting holes 12 are provided at the ends of the supporting stiffener 6 and at both ends of the supporting sealing plate 7. Fixing members 13 are installed in the mounting holes 12, and the supporting sealing plate 7 can be detached and installed through the fixing members 13.

[0032] The base 1 is also provided with an installation component 14, which is used to fix the base 1 to the crane ship.

[0033] In this invention, the support plate on the support rib is detachable and can be installed. In order to adapt to the concrete pouring diagram, a pouring hole can be provided at the upper end of the support plate. The interior can be completely filled through the pouring hole. At the same time, the mounting components are provided on the base, which can be installed on the crane ship relatively stably.

[0034] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the implementation of the present invention or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of patent protection of the present invention should be included within the scope of the present invention patent application.
