Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding engineering, in particular to an outer plate scaffolding suspension folding platform. Background Art

[0002] During shipbuilding, the outer hull walls require specialized coating operations, including surface impurity treatment, oil cleaning, sandblasting, and then application of various paints. Due to the large exterior construction area of ​​the cabin sections, prior to painting and other operations, scaffolding must be erected to facilitate construction. Traditional scaffolding erection methods utilize full-length scaffolding, requiring the scaffolding steel pipes to be placed on the ground. This large number of scaffolding pipes on the ground prevents simultaneous construction on the bottom of the sections, requiring the scaffolding to be removed before various construction operations can be performed. This results in a long processing cycle for the hull sections and impacts the ship's schedule.

[0003] Prior art application number: CN201910458291.1 discloses a chemical ship cargo oil tank tooling scaffolding, including a surrounding bulkhead scaffolding module and a top inverted scaffolding module, the surrounding bulkhead scaffolding module includes a number of angle steel brackets connected to the surrounding bulkhead eye plates, a number of supporting uprights arranged in pairs upright on the angle steel brackets, and a number of steel pipe brackets are connected between each pair of supporting uprights from bottom to top, and the steel pipe brackets are fixed to the surrounding bulkhead eye plates; the connection between the steel pipe brackets and the supporting uprights is fixed by a double-tube clamp module; the top inverted scaffolding module includes a number of hook rods distributed at intervals and hung on the top lifting ring inside the oil tank, and a supporting cross bar horizontally hung at the lower end of the hook rod, and the two ends of the supporting cross bar are fixedly connected to the supporting uprights by a double-tube clamp module. This technology is used to erect scaffolding inside the hull section. The surrounding bulkhead scaffolding modules need to be attached to the eye plates welded on the inner wall of the hull to be fixed. However, when constructing on the outer plate of the hull section, the outer plate surface is flat and there are no prefabricated eye plates, so the existing technology cannot be used to erect scaffolding.

[0004] The existing method for erecting segmented exterior panel scaffolding involves using traditional steel pipe fastener-type inverted scaffolding, which is connected to the segmented slope and two side surfaces using traditional steel pipe scaffolding. This method requires a large amount of scaffolding materials and labor-intensive assembly and disassembly. To address these issues and optimize the traditional scaffolding process, a folding platform fixture for the exterior panel scaffolding was designed. Summary of the Invention

[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0036] An outer plate scaffolding hanging and folding platform, as Figure 1-10 shown, includes an inner module 1 and an outer module 2. A plurality of laminates 3 are provided between the inner module 1 and the outer module 2. All of the plurality of laminates 3 are hingedly connected to the inner module 1 and the outer module 2 through hinge parts 4, as Figure 1-3 shown. In this embodiment, four laminates 3 are provided, so that the inner module 1 and the outer module 2 are formed into a "mu" character structure as Figure 2 、 3 shown. In actual use, the inner module 1 and the outer module 2 are welded by angle steel to form a fixed rectangular shape, and triangular stiffeners are welded at the corner parts to fix the frame-shaped structures of the inner and outer modules 2. And hinge parts 4 are provided on the side walls of the frames for connecting with the laminates 3, so that the laminates 3 and the inner module 1 and the outer module 2 form a deformable parallelogram structure; and a clamping head 6 for connecting with the outer plate of the ship is provided on the upper part of the inner module 1; when in use, the whole is hung on the outer plate of the ship section by using the clamping head 6, and the overall installation usage mode can be realized. Specifically, the hinge part 4 is as Figure 8 shown. A hinge plate 33 is provided at the corner of the laminate 3. A fixed-distance pipe 34 is provided between the hinge plate 33 and the angle steel column of the inner module 1 and the outer module 2. The fixed-distance pipe 34 is used to maintain the distance between the edge of the laminate 3 and the angle steel column, so that the laminate 3 can be retracted inside the angle steel column when folding, so as to be folded thinner. Bolts are sequentially passed through the angle steel column, the fixed-distance pipe 34 and the hinge plate 33 for fixation. It can be understood that in order to strengthen the firmness of the punching part of the angle steel column, a column angle steel reinforcement plate 35 is welded at its punching position.

[0037] As Figure 4 shown, the left side in the figure is the open state of this folding platform. At this time, each laminate 3 is in a horizontal state, and the laminate 3 is perpendicular to the inner module 1 and the outer module 2. At this time, operators can stand on the laminate 3 to perform operations. When this platform is not in use, it can be folded in the way shown on the right side in Figure 4 , that is, the outer module 2 is moved upward relative to the inner module 1. By using the deformation principle of the parallelogram, the inner and outer modules 2 can be made to approach each other, so as to reduce the space occupied during stacking; this device connects the inner side, the outer side and the laminate 3 of the scaffolding together to form a modular design, which is convenient for overall use and reduces the cumbersome operation of building the scaffolding with steel pipes one by one in the prior art, and has the advantage of high efficiency.

[0038] In order to improve the stability of the structure during use, a locking device 5 is provided between the inner module 1 and the outer module 2 to keep the scaffold in an open state; Figure 1 、 2 5, specifically, the locking device 5 includes a cross fixing mechanism 7 connected between the inner module 1 and the outer module 2, and the cross fixing mechanism 7 is evenly spaced in a plurality of groups in the height direction, thereby forming a multi-point reinforcement fixation in the entire height direction. It can be understood that the locking device 5 needs to be removed when in the folded state and installed again when needed, and the locking device 5 is used to maintain the stability of the platform.

[0039] The cross fixing mechanism 7 includes a cross rod 8 and a positioning pin 9. The positioning pin 9 is fixedly set on the side of the inner module 1 and the outer module 2. The cross rod 8 is pivotally connected in the middle of two steel pipes. The two ends of the steel pipe are provided with positioning holes 10 that match the positioning pin 9. The middle parts of the two cross rods 8 are pivotally connected. Each set of cross fixing mechanisms 7 includes four positioning holes 10 and four positioning pins 9, so that the cross fixing mechanism 7 and the inner and outer modules 2 form a triangular stable structure; during installation, the two positioning pins 9 at the diagonal positions are correspondingly inserted into the positioning holes 10 at both ends of the cross rod 8 to form a cross fixation, and the stability of the triangle is used to prevent the outer module 2 from sinking during use. The positioning pin 9 is a tongue-type pin; as Figure 6 As shown, when the positioning pin 9 is inserted into the positioning hole 10, the lock tongue movably connected to the end of the positioning pin 9 automatically droops to form a block to prevent the cross rod 8 from escaping from the positioning pin 9 during use.

[0040] As an embodiment of the positioning hole 10, the positioning hole 10 can be designed into a circular hole shape that matches the diameter of the positioning pin 9. The advantages of this structure are simple structure and good fixing effect. However, due to the small matching clearance between the circular hole and the positioning pin 9, it is easy for the circular hole and the positioning pin 9 to be misaligned due to slight deformation of the platform during use, resulting in a small fault tolerance rate of the circular hole-shaped positioning hole 10, and it is more difficult to install or remove.

[0041] As another embodiment of the positioning hole 10, in this embodiment, the positioning hole 10 is designed as a waist hole structure, such as Figure 5 As shown, both ends of the cross rod 8 are plate-shaped positioning ear plates 13, and waist-shaped positioning holes 10 are formed on the positioning ear plates 13. As shown in the figure, the extension direction of the waist hole is the same as the length direction of the steel pipe of the cross rod 8. In this embodiment, the waist hole positioning hole 10 can not only be more easily fitted on the positioning pin 9, but also allow the positioning pin 9 to have a margin for left and right movement in the positioning hole 10, thereby compensating for the error between the positioning pin 9 and the positioning hole 10 caused during processing or use, making it easier to install and remove the cross rod 8.

[0042] However, this will cause the outer module 2 to have a certain amount of vertical movement relative to the inner module 1, thus slightly reducing the stability of the overall structure. In order to solve this problem, under the premise of facilitating the installation and removal of the cross bar 8, and ensuring the firm fixation, it is necessary to compensate for the error caused by the deformation of the parts. In this embodiment, a hole adjustment device is added to the positioning ear plate 13, such as Figure 9 、 10 As shown, the hole position adjustment device includes a first toothed surface 14 formed on the surface of the positioning ear plate 13, the ridged teeth of the first toothed surface 14 are axially perpendicular to the length direction of the steel pipe, and also includes a clamping plate 15 arranged on both sides of the positioning ear plate 13. During installation, the clamping plates 15 are respectively arranged on both sides of the positioning ear plate 13, and a second toothed surface 16 meshing with the first toothed surface 14 is provided on the clamping plate 15. When the clamping plate 15 clamps the positioning ear plate 13, the ridged protrusions on the second toothed surface 16 are clamped into the first toothed surface 14, thereby fixing the position of the clamping plate 15 and the positioning ear plate 13. In this way, the position of the clamping plate 15 relative to the positioning ear plate 13 is adjusted, that is, the position of the clamping plate 15 is loosened. When the first toothed surface 14 and the second toothed surface 16 are disengaged when the clamping plates 15 on both sides are in the state of being clamped, the clamping plates 15 can be moved and adjusted in the axial direction of the cross rod 8. Furthermore, a through hole 17 for the positioning pin 9 to pass through is provided in the middle of the clamping plate 15. When in actual use, the positioning pin 9 passes through the waist-shaped positioning hole 10 and the through hole 17 in sequence. In this way, the position of the positioning pin 9 in the positioning hole 10 can be easily adjusted in the unlocked state; when locking and fixing are required, only the first toothed surface 14 and the second toothed surface 16 need to be meshed to make the clamping plates 15 on both sides clamped on the positioning ear plates 13, that is, the position of the positioning pin 9 can be fixed through the through hole 17. Specifically, Figure 9 、 10 As shown, clamping bolts 18 are provided at both ends of the clamping plates 15. In this embodiment, the two clamping plates 15 are fastened by providing clamping bolts 18 through both ends of the clamping plates 15. After fastening, the position of the locating pin 9 in the waist-shaped locating hole 10 can be fixed. This not only can adapt to the positional errors that are difficult to avoid during the use and processing of parts, but also can ensure the stability of the entire platform after locking.

[0043] As an embodiment of the locking device 5, the cross fixing mechanism 7 is used for positioning in the above description. In this embodiment, as a supplement, specifically, the locking device 5 further includes a limiting tube 11, which is fixedly arranged on the inner module 1. Figure 4As shown, the limiting tube 11 can be welded from a round tube of a certain length, or can be processed from a plate to achieve the same effect. The limiting tube 11 is arranged near the hinge portion 4 and is perpendicular to the inner module 1. The upper edge of the limiting tube 11 forms an abutment surface 12, so that when the layer 3 rotates to a position perpendicular to the inner module 1, it abuts against the abutment surface 12 to form a limit. In actual use, when the outer template is rotated to open, the layer 3 is pulled to rotate to a horizontal state. At this time, the lower edge of the layer 3 is stuck on the abutment surface 12 on the upper edge of the limiting tube 11. Therefore, the limiting tube 11 in this embodiment can not only play an angular positioning role, but also limit the angle of opening of the layer 3 during the opening and assembly process, preventing excessive opening, which would cause a large offset of the cross-fixing mechanism 7 and make assembly difficult. Secondly, during the hanging process, the outer module 2 has a tendency to fall under the action of its own weight, and the limiting tube 11 in this embodiment acts as a stop.

[0044] As another embodiment of the locking device 5, the locking device 5 further includes a locking transverse tube 19, such as Figure 5 As shown, the inner module 1 and the outer module 2 are both provided with transversely arranged locking lugs 20. The locking lugs 20 on each side are symmetrically arranged. A channel is formed between the two locking lugs 20 for the end of the locking transverse tube 19 to be inserted. The end of the locking transverse tube 19 is inserted into the locking lug 20 and fixed with a locking bolt 21. Figure 6 As shown, the locking ear plate 20 is arranged horizontally, and the locking transverse tube 19 is inserted horizontally into the locking ear plate 20, which also plays a locking role on the inner module 1 and the outer module 2 to prevent the far end of the outer module 2 from falling. In summary, this device adopts a triple locking device 5 of a cross fixing mechanism 7, a limit tube 11, and a locking transverse tube 19 to fix the platform, effectively ensuring safe operation.

[0045] Based on practical requirements, this suspended folding platform is designed with a 2m height and four decks (3). The top deck (3) can be protected by a guardrail to form a work area. The three lower decks are protected by outer modules (2), which also feature integrated ladders (22) for access. Each platform is 2236mm long and 940mm wide. Based on the safe load calculation, each platform can accommodate three people, fully meeting construction requirements.

[0046] Specifically, such as Figure 3 、 7As shown, the folding platform is also equipped with a climbing passage connecting each floor. The climbing passage includes a ladder 22 formed on the outer module 2 and a ladder cover 23 formed on the floor 3. The ladders 22 on each floor of the folding platform are staggered, and the upper ends of the ladders 22 are connected to the ladder cover 23 of the upper floor 3. The ladder cover 23 is hinged to the floor 3 on one side via a ladder hinge 25 and fastened to the floor 3 on the other side via a ladder angle 24. People can climb the ladder 22 to pass through the upper floor 3, and then open the ladder cover 23 on the floor 3 from the bottom to establish communication between the upper and lower floors, and then close the ladder cover 23.

[0047] like Figure 2 、 3 As shown, expansion rods 26 are provided on both sides of the folding platform. A plurality of expansion rods 26 are evenly spaced on the inner module 1 and the outer module 2. The expansion rods 26 can be used for laying pipelines between the platforms and provide a fulcrum for laying scaffolding extending laterally. Fork-leg square tubes 27 are respectively provided on the outer sides of the inner module 1 and the outer module 2. The fork-leg square tubes 27 are used for forklifts to transport the platform.

[0048] The clamping part 6 includes a clamping plate 28 welded to the upper end of the inner module 1, as shown in FIG. Figure 5 As shown, the clamping plate 28 is provided with a downward-facing U-shaped bayonet 29. An inner lining plate 30 is provided on the inner wall of the U-shaped bayonet 29, through which fastening screws 31 are screwed. The clamping plate 28 also has lifting lugs 32 on its side. The assembled platform is hoisted as a whole using the lifting lugs 32. When the platform is close to the ship's sectioned outer plate, the clamping head 6 is connected to the outer plate. Specifically, the U-shaped bayonet 29 is clamped to the upper edge of the outer plate, and then the platform is positioned using the fastening screws 31, thus achieving rapid installation.

[0049] The use of the external panel scaffolding suspended folding platform reduces the use of traditional steel pipe scaffolding materials, improves erection efficiency, and optimizes the traditional scaffolding process. Benefits: For example, a conventional scaffolding suspended platform tooling measuring 2.24*6.45*0.94 (length*height*width) requires five people two hours to erect this type of steel pipe scaffolding, totaling 10 hours. Dismantling requires another five people one and a half hours, totaling 7.5 hours, for a total of 17.5 hours, not including the trucking and transport of the necessary materials. Using the improved scaffolding suspended folding platform tooling of the present invention, tests have shown that erection and dismantling require only two people three hours, totaling 6 hours, significantly reducing construction costs.

[0050] The method for using the outer plate scaffolding hanging folding platform of the present invention comprises the following steps:

[0051] S1: pre-assemble the inner module 1, the outer module 2, and the layer 3 into a foldable and stackable configuration, and hinge the four corners of the layer 3 to connect the inner module 1 and the outer module 2 through the hinge parts 4 to form a pre-assembled structure with a deformable parallelogram structure;

[0052] S2: Use a forklift to transport the parts of the folding platform to the construction site. The forklift uses the fork leg square tube 27 to move the pre-assembled structure as a whole to the construction site;

[0053] S3: Prop up the pre-assembled structure in a stacked position so that the layer 3 is perpendicular to the inner module 1 and the outer module 2, and install the locking device 5. Insert the locking transverse tubes 19 at the upper and lower ends into the locking lugs 20 and tighten them with bolts; install multiple sets of cross fixing mechanisms 7 on both sides to form a triangular stable structure, and complete the assembly;

[0054] S4: Use the lifting equipment to lift the folding platform upright using the lifting lugs 32, and then lift it onto the segmented outer plate and fix it to the segmented outer plate through the clamping head 6;

[0055] S5: Folding platforms are suspended on both sides of the hull segment, and scaffolding is set up between the folding platforms on both sides via expansion rods 26.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
