Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a multi-functional flange processing platform. Background Technology

[0002] In the construction of bearing-type floating cranes, the slewing chassis and the lower cylinder are connected by a slewing bearing. The slewing function of the floating crane is achieved by the rotation of the rotor inside the slewing bearing. The slewing bearing is fitted with the flange face of the upper slewing chassis and fixed with bolts; similarly, the slewing bearing is fitted with the flange face of the lower cylinder and fixed with bolts. Therefore, the precision requirements for the flange face and bolt holes are very high, necessitating machining. To ensure that the machining accuracy meets the requirements, the flanges are usually machined after the lower cylinder is installed onto the hull base (which is installed on the main deck of the ship) during the final assembly of the floating crane. The machining equipment consists of a base and a rocker arm. The base is self-powered and fixed not in the middle area of ​​the cylinder. The flange face is machined by the full rotation of the rocker arm.

[0003] In existing technologies, the base of the processing equipment weighs approximately 16-20 tons. To accommodate the equipment in the middle of the lower cylinder, a support platform is typically erected from the main deck upwards, reaching approximately the height of the cylinder flange. This requires significant labor and material costs. Furthermore, for personnel safety during processing operations, scaffolding must be fully erected in the area outside the support platform. After processing is completed, the platform and scaffolding must be dismantled. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-functional flange processing platform that can solve the problems of large labor and material costs required for setting up a support platform in the prior art, as well as the problem of needing to fully erect scaffolding in areas outside the support platform.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a multi-functional flange processing platform, which is installed on the hull base of the ship's main deck. Its innovation lies in: including... The lower cylinder is horizontally positioned at the top of the hull base, and its central axis is vertically positioned. The main body of the multi-functional machining platform is located inside the lower cylinder and has a cross-shaped structure, including a first H-beam arranged horizontally, a second H-beam arranged vertically, and a third H-beam arranged at an inclination. A flange is installed at the top of the lower cylinder, and the distance between the upper surface of the flange and the upper surface of the multi-functional machining platform body is 350mm-400mm.

[0006] Furthermore, multiple lifting lugs are installed on the upper and lower surfaces of the third H-beam on the main body of the multi-functional machining platform. The extended sides of the third H-beam are all welded to the inner wall of the lower cylinder. No connecting plate is used for this welding, which increases the length of the weld seam connected to the inner wall of the lower cylinder, ensuring the overall strength during hoisting. The weld seam connected to the inner wall of the lower cylinder must also meet the flaw detection requirements. At the same time, it can not only meet the hoisting of the main body of the multi-functional machining platform, but also allow the entire lower cylinder to be horizontally hoisted and flipped after the machining platform is installed inside the lower cylinder.

[0007] Furthermore, the first H-beam and the second H-beam of the main body of the multi-functional machining platform are connected to the inner wall of the lower cylinder through connecting plates, which can reduce the amount of welding and facilitate disassembly.

[0008] Furthermore, connecting plates are installed between multiple lifting lugs on the upper surface and between multiple lifting lugs on the lower surface of the multi-functional machining platform body. These connecting plates are all welded to the third H-beam, which ensures the lifting force while also increasing stability. The connecting plate includes a convex body, the top side length of which is greater than the bottom side length, and a relief groove is provided at each of its two apex corners to prevent the two apex corners from hitting the inner corner of the third H-shaped steel.

[0009] Furthermore, a steel plate is also placed at the center of the main body of the multi-functional machining platform, and the steel plate is placed in front of the hoisting and processing equipment arranged in front of the main body of the multi-functional machining platform. The thickness of the steel plate is ≥40mm, which can improve the stability of the processing equipment during operation.

[0010] Furthermore, the main body of the multi-functional machining platform is also equipped with scaffolding pipes and scaffold boards, which are securely tied to provide walking space for flange processing workers.

[0011] Furthermore, the lower cylinder body is also provided with a circular outer platform, and an inclined ladder is provided between the outer side of the hull base and the outer platform, which can help operators safely complete the processing and drilling of the flange.

[0012] Furthermore, a first connecting beam is provided between adjacent second H-beams and third H-beams, and a second connecting beam is provided between adjacent first H-beams and third H-beams, and all the first connecting beams and second connecting beams form an octagonal structure.

[0013] The advantages of this utility model are: 1. This structure eliminates the need to erect a support platform from the main deck of the ship and to build a full scaffold, saving material and labor costs. At the same time, the main body of this multi-functional machining platform can also serve as a process support during the construction of the lower cylinder. In addition, the main body of the multi-functional machining platform is equipped with lifting lugs. After the main body of the multi-functional machining platform is installed on the lower cylinder, it can be used to lift and turn the lower cylinder structure horizontally, avoiding the need to install lifting lugs on the cylinder structure again and to dismantle and grind them. It meets the lifting requirements of the lower cylinder and is a multi-functional platform.

[0014] 2. The main body of the multi-functional machining platform uses H-beams as the main structure, which increases the stability of the platform and reduces the vibration caused by the rotation of the machining equipment.

[0015] 3. The lower cylinder is prone to deformation during manufacturing, especially during hoisting. Installing the multi-functional machining platform acts as an additional process support, effectively controlling the roundness of the cylinder and reducing the construction difficulty of installation with the flange and hull base.

[0016] 4. Personnel can directly access the inclined ladder and external platform on the outside of the cylinder and hull base for processing operations, and the platform is also easy to dismantle after the processing is completed. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] In the construction of a bearing-type floating crane, the slewing chassis 6 and the lower cylinder 3 are connected by a slewing bearing 7. The slewing function of the floating crane is realized by the rotation of the rotor inside the slewing bearing 7.

[0025] like Figure 1-5 The multi-functional flange processing platform shown is mounted on the hull base 2 of the main deck 1 of a ship and includes a lower cylinder 3, a multi-functional machining platform body 4, and a flange 5.

[0026] The lower cylinder 3 is horizontally positioned at the top of the hull base 2, and the central axis of the lower cylinder 3 is vertically positioned.

[0027] The main body 4 of the multi-functional machining platform is located inside the lower cylinder 3. It is a cross-shaped structure composed of multiple H-beams. These multiple H-beams are all 400x200x8x13 H-beams, which can increase the strength of the structure. In addition, the use of H-beam structure is more conducive to laying mats and scaffold boards on the platform.

[0028] Flange 5 is installed at the top of the lower cylinder 3, and the distance between the upper surface of flange 5 and the upper surface of the multi-functional machining platform body 4 is 350mm-400mm.

[0029] The main body 4 of the cross-shaped multi-functional machining platform includes a longitudinally arranged second H-beam 42, two transversely arranged first H-beams 41, and four inclined third H-beams 43. A first H-beam 41 is arranged transversely on both sides of the middle of the second H-beam 42, and an inclined third H-beam 43 is provided between adjacent first H-beams 41 and second H-beams 42.

[0030] A first connecting beam 44 is fully welded between adjacent second H-beams 42 and third H-beams 43, and a second connecting beam 45 is fully welded between adjacent first H-beams 41 and third H-beams 43. All the first connecting beams 44 and second connecting beams 45 form an octagonal structure. Both the first connecting beams 44 and the second connecting beams 45 are made of φ168x10 steel pipes, which not only increases the stability of the platform but also facilitates the laying of scaffold boards.

[0031] The extension sides of the first H-beam 41 and the second H-beam 42 of the main body 4 of the multi-functional machining platform are connected to the inner wall of the lower cylinder 3 by a connecting plate 47, which can reduce the amount of welding and facilitate disassembly.

[0032] Four 40T lifting lugs 46 are installed on the upper and lower surfaces of the third H-beam 43 on the main body 4 of the multi-functional machining platform. The extended sides of the third H-beam 43 are welded to the inner wall of the lower cylinder 3. No connecting plate is used for this welding, which increases the length of the weld seam connecting to the inner wall of the lower cylinder 3 and ensures the overall strength during hoisting. The weld seam connecting to the inner wall of the lower cylinder 3 must also meet the flaw detection requirements. At the same time, it can not only meet the hoisting of the main body 4 of the multi-functional machining platform, but also allow the entire lower cylinder 3 to be horizontally hoisted and flipped after the machining platform is installed inside the lower cylinder 3.

[0033] Furthermore, the lifting lugs 46 on the upper surface correspond one-to-one with the lifting lugs 46 on the lower surface, and two symmetrically arranged connecting plates 9 are provided inside the third H-beam 43, which can ensure the lifting force and also increase the stability of the H-beam.

[0034] like Figure 6 The connecting plate 9 shown includes a convex body, the top side length of which is greater than the bottom side length, and a relief groove 11 is provided at each of its two apex corners to prevent the two apex corners from hitting the inner corner of the third H-beam 43.

[0035] The third H-beam 43 includes two horizontal sections 101 and a vertical section 102 arranged in an H-shape. The top sides of the two connecting plates 9 are aligned with the vertical section 102 of the third H-beam and pushed to the bottom and welded. Then, the space between the two connecting plates 9 and the upper and lower lifting lugs 46 forms a space that can just accommodate the third H-beam 43.

[0036] A steel plate 12 is also placed at the center of the main body 4 of the multi-functional machining platform. The steel plate 12 is placed in front of the hoisting and processing equipment arranged in front of the main body 4 of the multi-functional machining platform, and the thickness of the steel plate 12 is ≥40mm, which can improve the stability of the processing equipment during operation.

[0037] The main body 4 of the multi-functional machining platform is also equipped with scaffolding pipes and scaffold boards, which are securely tied to provide a walking path for the flange 5 processing personnel.

[0038] A circular outer platform 8 is provided on the outer ring of the lower cylinder 3, and an inclined ladder is provided between the outer side of the hull base 2 and the outer platform 8, which can help the operators safely complete the processing and drilling of the flange 5.

[0039] The working principle of this patent: Before machining flange 5, a pad with a thickness of ≥40mm is laid in the middle of the main body 4 of the multi-functional machining platform. The size of the pad depends on the size of the machining equipment. The purpose of the pad is to make the machining equipment run more smoothly. Then, scaffolding pipes are arranged on the main body 4 of the multi-functional machining platform, and scaffolding boards are laid and securely tied for the workers to walk on. In addition, an outer platform 8 is installed on the outer ring structure of the lower cylinder 3. Workers can go from the ladder platform on the hull base 2 to the outer platform 8, and then to the machining platform to safely complete the machining and drilling of flange 5.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
