Description

Technical Field

[0001] This application relates to the field of support platform technology for building construction, and in particular to a curved outer plate work platform with adjustable function. Background Technology

[0002] The global shipping industry is facing the dual challenges of an urgent need for green and low-carbon transformation and the need to upgrade its aging fleet. Suezmax crude oil tankers, with their moderate cargo capacity and main dimensions, can flexibly adapt to most ports worldwide and pass through the Suez Canal fully loaded, significantly shortening voyages and reducing transportation costs, demonstrating excellent economic performance on major crude oil routes from the Middle East and West Africa to Europe and the United States. However, with tankers over 20 years old accounting for 17% of the global fleet, the aging problem of the Suezmax fleet is particularly prominent. Older vessels generally suffer from low energy efficiency, excessive carbon emissions, and insufficient levels of intelligent technology, making it difficult to meet the EEDI Phase III energy efficiency standards and carbon intensity index (CII) requirements proposed by the International Maritime Organization (IMO). At the same time, increasingly stringent environmental regulations (such as the EU carbon tax and ship exhaust emission limits) and increased scrapping volumes have led to a structural capacity gap, resulting in a growing market demand for a new generation of energy-efficient and environmentally friendly Suezmax crude oil tankers.

[0003] Shipbuilding often requires welding, grinding, painting, and inspection of outer plates with complex curved surfaces. Because the outer surface of the curved plate has a continuously changing curved shape, the height of the work point for construction workers also changes constantly during the operation.

[0004] Traditional construction methods typically use scaffolding or simple platforms at fixed heights. When workers are working continuously, they need to frequently bend over, squat down, or laboriously raise their arms or stand on tiptoe depending on the height of the work point. This not only leads to extremely high labor intensity and rapid fatigue for workers, but also poses safety hazards due to unstable posture.

[0005] In other words, existing technologies have the following technical problems: ordinary support equipment cannot adapt to the changes in the curved surface of the outer panel, resulting in inconvenience and low efficiency for construction workers. Therefore, an adjustable curved panel working platform is proposed to address the above problems. Summary of the Invention

[0006] This embodiment provides an adjustable curved outer plate working platform to solve the problem that ordinary support equipment in the prior art cannot adapt to the changes in the curved surface of the curved outer plate, resulting in inconvenience and low efficiency for construction personnel.

[0007] According to one aspect of this application, an adjustable curved outer plate working platform is provided, including a bottom platform, a fixed bracket is fixedly provided on the upper surface of the bottom platform, and a movable inner platform is also provided on the inner side of the bottom platform. A lifting and adjusting mechanism is also fixedly connected to the side of the bottom platform. The lifting and adjusting mechanism is connected to the inner platform and is used to adjust the overall height of the inner platform. The inner platform is also equipped with a stepped support assembly consisting of several support plates, which are movable and adjustable.

[0008] Furthermore, the bottom platform is also fixedly equipped with wheels to facilitate its movement.

[0009] Furthermore, the inner platform and the bottom platform move linearly together via fixed brackets.

[0014] Furthermore, the adjustment unit includes a U-shaped fixed base, positioning sliders, support seats, and support frames. The U-shaped fixed base is fixedly installed on the bottom surface of the inner platform and located directly below the support platform. A guide rail is fixedly installed on the upper surface of the U-shaped fixed base. Positioning sliders are slidably connected to both sides of the guide rail. Support seats are fixedly connected to both positioning sliders. One end of the support frame is rotatably connected to the support seat. Both support frames are rotatably connected to the fixed base frame. The fixed base frame is fixedly installed on the bottom surface of the support platform.

[0015] Furthermore, a threaded rod is rotatably connected between the two side walls of the U-shaped fixed base. The threaded rod passes through the support base and is threadedly engaged with the support base. An adjusting disc is also rotatably connected to the side wall of the U-shaped fixed base. One end of the adjusting disc is fixedly connected to one end of the threaded rod.

[0016] Furthermore, the threaded rod is a double-helix screw, with both ends of the threaded rod passing through two support seats and threadedly engaged with the support seats.

[0017] In order to solve the problem in the prior art where ordinary support equipment requires workers to frequently bend over or raise their arms due to the changing curvature of the outer wall of the curved outer panel, the present application provides a working platform with a movable inner platform.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figure 1 and Figure 2 As shown, the adjustable curved outer plate working platform includes a bottom platform 1, a fixed bracket 3 is fixedly installed on the upper surface of the bottom platform 1, and a movable inner platform 4 is also installed on the inner side of the bottom platform 1. A lifting adjustment mechanism 6 is also fixedly connected to the side of the bottom platform 1. The lifting adjustment mechanism 6 is connected to the inner platform 4 and is used to adjust the overall height of the inner platform 4. The inner platform 4 is also provided with a stepped support assembly 7 consisting of several support plates 701, which are movable and adjustable.

[0023] To address the problem in existing technologies where conventional support equipment requires workers to frequently bend over or extend their arms due to the varying curvature of the outer wall of the curved outer panel 8, resulting in inconsistent heights during construction, this application designs a working platform with a movable inner platform 4. The height of the inner platform 4 can be flexibly adjusted via a lifting and adjusting mechanism 6, facilitating operation on different curved outer panels 8. Furthermore, a stepped support assembly 7, composed of several support plates 701, is provided. The height of the support plates 701 is flexibly adjustable, forming a stepped shape, allowing construction workers to easily step on the steps and climb to different positions to perform construction operations on the surface of the curved outer panel 8. This design is particularly suitable for construction work on curved outer panels 8.

[0024] Preferably, to accommodate construction workers of different weights and working conditions carrying tools, and to enhance the overall load-bearing capacity of the platform, the inner frame of the bottom platform 1 is welded from channel steel, and the inner platform 4 is formed by stamping steel plates with reinforcing ribs. This reinforced structural design ensures the structural strength and reliability of the platform when supporting construction workers and equipment.

[0025] For specific technical solutions, please refer to Figure 1 and Figure 2 As shown, a walking wheel 2 is also fixedly installed on the bottom surface of the bottom platform 1 to facilitate the movement of the bottom platform 1.

[0026] Specifically, to address the potential for accidental platform movement during operation and to ensure stable positioning, at least two of the aforementioned wheels 2 are swivel wheels equipped with foot brakes. After the platform has moved to a suitable work position, the foot brakes can be applied to lock the wheels 2, preventing platform movement during construction and ensuring operational safety.

[0027] As a further technical solution, see Figure 2 As shown, the inner platform 4 and the bottom platform 1 move linearly together via fixed brackets 3. Four fixed brackets 3 are provided, which are fixed at the four corners of the upper surface of the bottom platform 1. A linear slide rail 301 is also fixedly connected to the side wall of the fixed bracket 3. A guide groove 401 is provided at each of the four corners of the inner platform 4. The guide groove 401 slides with the linear slide rail 301. Through this technical solution, the inner platform 4 can move up and down in a straight line by setting the fixed brackets 3, which plays a role in positioning and guiding.

[0028] For specific technical solutions, please refer to Figure 1 and Figure 4As shown, the lifting and adjusting mechanism 6 includes a fixed base 601, a hydraulic cylinder 602, a connecting plate 603, and a connecting guide rod 604. The fixed base 601 is fixedly installed on the side of the bottom platform 1, and the hydraulic cylinder 602 is fixedly connected to the upper surface of the fixed base 601.

[0029] As a preferred technical solution, please refer to Figure 4 As shown, a connecting plate 603 is fixedly connected to the top of the hydraulic cylinder 602, and one end of a connecting guide rod 604 is fixedly connected to the bottom surface of the connecting plate 603. The other end of the connecting guide rod 604 is fixedly connected to the upper surface of the inner platform 4. Through this technical solution, the connecting plate 603 can be moved by the extension and retraction of the hydraulic cylinder 602, thereby driving the connecting guide rod 604 to move. The inner platform 4 is moved by the connecting guide rod 604, realizing the moving and lifting function of the inner platform 4, which facilitates the carrying of construction personnel to a suitable height for construction operations on the curved outer plate 8.

[0030] Preferably, in order to solve the problem of swaying or deviation that may occur during the lifting and lowering of the hydraulic cylinder 602 and to enhance the overall structural stability, multiple connecting guide rods 604 can be provided and symmetrically distributed on both sides of the hydraulic cylinder 602. This can effectively prevent the inner platform 4 from twisting or tilting during the lifting and lowering process, ensuring the stability and safety of the construction process.

[0031] For a preferred technical solution, please refer to Figure 2 As shown, the hydraulic cylinder 602 is a manually operated hydraulic cylinder. The side of the hydraulic cylinder 602 is provided with a pressing handle 605 for operation. With this technical solution, the hydraulic cylinder 602 can be lifted by the operator repeatedly pressing the pressing handle 605 manually.

[0032] For specific technical solutions, please refer to Figure 5 and Figure 6 As shown, the stepped support assembly 7 consists of several support plates 701 and an adjustment part for adjusting the support plates 701. Several grooves are provided on the inner platform 4. The support plates 701 are disposed in the grooves of the inner platform 4 and slide in cooperation with the inner platform 4. An adjustment part is fixedly connected to the bottom surface of the support plates 701.

[0033] As a further technical solution, the adjustment unit includes a U-shaped fixed base 702, a positioning slider 704, a support base 705, and a support frame 706. The U-shaped fixed base 702 is fixedly installed on the bottom surface of the inner platform 4 and directly below the support plate 701. A guide rail 703 is fixedly installed on the upper surface of the U-shaped fixed base 702. Positioning sliders 704 are slidably connected to both sides of the guide rail 703. Support bases 705 are fixedly connected to both positioning sliders 704. One end of the support frame 706 is rotatably connected to the support base 705. Both support frames 706 are rotatably connected to a fixed base frame 707, which is fixedly installed on the bottom surface of the support plate 701. Through this technical solution, the movement of the positioning slider 704 can drive the support base 705 to move, thereby driving the support frame 706 to rotate angularly, thus realizing the function of adjusting the height position of the support plate 701.

[0034] As a preferred technical solution, please refer to Figure 6 As shown, a threaded rod 708 is rotatably connected between the two side walls of the U-shaped fixed base 702. The threaded rod 708 passes through the support base 705 and is threadedly engaged with the support base 705. An adjusting plate 709 is also rotatably connected to the side wall of the U-shaped fixed base 702. One end of the adjusting plate 709 is fixedly connected to one end of the threaded rod 708.

[0035] For further details, please refer to [link / reference]. Figure 6 As shown, the threaded rod 708 is a double-helix screw. Both ends of the threaded rod 708 pass through two support seats 705 and are threadedly engaged with the support seats 705. Through this technical solution, the threaded rod 708 can be rotated by manually rotating the adjusting disc 709. Thus, the rotation of the threaded rod 708 can drive the support seats 705 on both sides to move synchronously, thereby adjusting the height of the support platform 701 and realizing the adjustment function.

[0036] For specific applications of the stepped support component 7, please refer to [the relevant documentation / reference]. Figure 7 and Figure 8 As shown, the threaded rods 708 of different support plates 701 can be driven to rotate by manually rotating the adjusting discs 709 corresponding to them. Since the threaded rods 708 are double helical screws, they will synchronously drive the two support seats 705 on them to move towards or away from each other; the movement of the support seats 705 will push or pull the support frame 706 that is hinged to them, thereby raising or lowering the support plates 701; by adjusting the adjusting parts under each support plate 701 in sequence, several support plates 701 can be arranged in a stepped pattern from low to high on the inner platform 4.

[0037] This stepped arrangement allows construction workers to easily reach suitable positions for working on different height parts of the curved outer panel 8 by stepping on the support platforms 701 at different heights, much like climbing stairs. When the curvature of the outer panel 8 causes continuous changes in construction height, construction workers do not need to frequently bend over excessively or strain their arms on a single plane. They can simply move laterally or step up or down on the steps to maintain the optimal match between their height and the current construction point on the outer panel 8, thereby significantly reducing labor intensity and improving construction efficiency and operational comfort. In addition, when it is necessary to adjust the overall working height, the lifting and adjusting mechanism 6 can be activated, and the hydraulic cylinder 602 can drive the entire inner platform 4 and its stepped support components 7 to rise and fall together, achieving rapid adaptation to different vertical areas of the outer panel 8. The entire platform can be moved by the wheels 2, further enhancing the flexibility of use.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
