Description

[0001] The invention belongs to the field of shipbuilding, relates to the manufacture of a heat-insulating layer, and in particular to an adaptive scraping device with a variable angle. Background Art

[0002] The cargo holds of LNG (Liquefied Natural Gas) vessels require two layers of thermal insulation to maintain an absolute low temperature of -163°C. The insulation layer in the MARK III membrane containment system consists of modular polyurethane panels. The dihedral workpieces installed in the corners are composed of a FSB (Fiberglass Sheeting) on the back of the secondary sheet, a secondary sheet consisting of two single-leg panels, a FSB on the front of the secondary sheet, and a main sheet bonded together. The FSB is a composite waterproof fabric or film. It is adhered to the secondary sheet with glue. To ensure the adhesion and precision of the FSB to the secondary sheet, manual scraping is currently used to smooth the FSB and eliminate any bubbles in the glue. However, due to the large size and variety of sizes of the secondary sheets, the sizes and angles of the different sizes vary. Furthermore, the secondary sheets are dihedral in shape, requiring the FSB to be adhered to both sides. This manual process is labor-intensive and difficult to apply evenly within the specified thickness range, resulting in poor product quality. Summary of the Invention

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is described in detail in the following embodiments with reference to the accompanying drawings.

[0025] Example

[0026] Figure 1 This is a schematic diagram of the structure of the variable-angle adaptive scraping device before flipping. Figure 2 It is a schematic diagram of the structure of the variable-angle adaptive scraping device after flipping.

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a variable-angle adaptive scraping device for scraping FSB on a secondary component to eliminate glue bubbles between the FSB and the secondary component, ensuring smooth adhesion between the two. The variable-angle adaptive scraping device includes a frame body 10, two mounting frames 20, multiple lifting angle adjustment mechanisms 30, a synchronous drive mechanism 40, two adaptive pressure roller assemblies 50, two Y-axis adjustment mechanisms 60, and two X-axis travel mechanisms 70. A detailed description is provided below. The X-axis and Y-axis shown in the figure represent the length and width directions, respectively.

[0028] The rack body 10 is used to mount and carry components and is approximately rectangular. Each mounting bracket 20 is rectangular, and two mounting brackets 20 are symmetrically arranged on either side of the rack body 10. The adjacent sides of the top surfaces of the two mounting brackets 20 are hinged to the bottom surface of the rack body 10 via multiple hinges distributed along the length.

[0029] Multiple lifting angle adjustment mechanisms 30 are mounted on the frame body 10 and are evenly spaced along the length of the frame body 10. Each lifting angle adjustment mechanism 30 is connected to two mounting frames 20 and is used to adjust the angle between the two mounting frames 20. Specifically, each lifting angle adjustment mechanism 30 includes a lifting mechanism, a lifting slider 32, and two connecting rods 33. The lifting mechanism is mounted on the frame body 10, and the lifting slider 32 is connected to the lifting mechanism and is driven by the lifting mechanism to move up and down. The frame body 10 is provided with a slideway for the lifting slider 32 to slide. The two connecting rods 33 are arranged on either side of the lifting slider 32. One end of the two connecting rods 33 is hinged to the two sides of the lifting slider 32, and the other end of the two connecting rods 33 is hinged to the top surface of the two mounting frames 20. When the lifting slider 32 is raised or lowered, the two connecting rods 33 drive the two mounting frames 20 to rotate, thereby changing the angle between the two mounting frames 20.

[0030] In this embodiment, the lifting mechanism uses a worm gear screw lift 31, which has the advantages of high precision, compact structure, light weight, and a wide range of power sources. More importantly, it can be used in combination with multiple machines. The base of the worm gear screw lift 31 is installed on the top surface of the frame body 10, and the nut 623 of the worm gear screw lift 31 is connected to the lifting slider 32; the length of the two connecting rods 33 ensures that when the variable-angle adaptive scraping device is not flipped and the lifting slider 32 is in the lowest position, the height position of the adjacent sides of the two mounting frames 20 is still lower than the height position of the opposite sides.

[0031] The synchronous drive mechanism 40 is mounted on the frame body 10 and connected to the lifting mechanisms of the multiple lifting angle adjustment mechanisms 30. The synchronous drive mechanism 40 is used to synchronously drive the lifting mechanisms of the multiple lifting angle adjustment mechanisms 30. Specifically, the synchronous drive mechanism 40 includes multiple synchronization shafts 41 and a drive member. The lifting mechanisms of each adjacent two lifting angle adjustment mechanisms 30 are connected by a synchronization shaft 41, and the drive member is connected to the lifting mechanism at the end via a synchronization shaft 41.

[0032] In this embodiment, because the angle between the two mounting frames 20 does not need to be adjusted frequently in actual use, there is no need to frequently drive the lifting mechanism, so the driving member is a handle 42, and the power source is manual, which is more economical and practical. At the same time, a clamping member 43 is configured. The clamping member 43 is installed on the top surface of the frame body 10 and is used to clamp the synchronization shaft 41 connected to the handle 42, which can meet the high-precision positioning requirements.

[0033] Figure 3 This is a side view of the variable angle adaptive scraping device. Figure 4 yes Figure 3 The cross-sectional view of the AA line, Figure 5 yes Figure 3Cross-sectional view along line BB.

[0034] Two adaptive pressure roller assemblies 50 are respectively arranged on the bottom surfaces of the two mounting frames 20, and the adaptive pressure roller assemblies 50 are used to contact with the FSB and flatten it. Figure 3 and 4 As shown, each adaptive pressure roller assembly 50 comprises a roller frame 51, a roller frame 52, multiple mandrels 53, multiple springs 54, and a pressure roller 55. The roller frame 51 is mounted on the slider of the Y-axis linear guide 61 of the Y-axis adjustment mechanism 60. The roller frame 52 is connected to the roller frame 51 below via multiple mandrels 53 and extends along the width of the mounting frame 20. The multiple mandrels 53 are spaced apart along the width of the mounting frame 20. Multiple springs 54 are respectively mounted on the multiple mandrels 53, each spring 54 resting between the roller frame 51 and the roller frame 52. The springs 54 are used to achieve the adaptive function. The pressure roller 55 is mounted on the roller frame 52 at both ends, with a gap between the ends and the roller frame 52 to further ensure that the pressure roller 55 can adapt to the shape of the sub-layer component. In this embodiment, the spring 54 is a rectangular spring, which has the advantages of high strength and long service life; the pressure roller 55 is a polyurethane pressure roller, which is made of the same material as the secondary layer and can protect the contacting FSB surface.

[0035] Two Y-axis adjustment mechanisms 60 are respectively provided on the two mounting frames 20. Each Y-axis adjustment mechanism 60 is connected to the adaptive pressure roller assembly 50 on the mounting frame 20, and is used to adjust the position of the adaptive pressure roller assembly 50 in the width direction of the mounting frame 20. Because when the angle between the two mounting frames 20 changes, if the positions of the two adaptive pressure roller assemblies 50 remain unchanged, the folded corners of the FSB may not be scraped by the pressure roller 55 during the scraping operation. Therefore, it is necessary to adjust the positions of the two adaptive pressure roller assemblies 50 so that the positions of the two adaptive pressure roller assemblies 50 match the surface of the FSB to be scraped, ensuring that the pressure roller 55 covers the folded corners of the FSB. Figures 3 to 5 As shown, each Y-axis adjustment mechanism 60 includes a Y-axis linear guide 61 and a lead screw mechanism 62. The slide rail of the Y-axis linear guide 61 is mounted on the movable base 72 of the X-axis travel mechanism 70 along the width direction of the mounting frame 20 on which it is mounted. The roller frame 51 of the adaptive pressure roller assembly 50 is mounted on the slider of the Y-axis linear guide 61. The lead screw mechanism 62 is mounted on the movable base 72 of the X-axis travel mechanism 70 along the width direction of the mounting frame 20 on which it is mounted and is connected to the roller frame 51 of the adaptive pressure roller assembly 50.

[0036] In this embodiment, the screw mechanism 62 includes a screw base 621, a trapezoidal screw 622, a nut 623, and a handwheel 624. The screw base 621 is mounted on the moving base 72 of the X-axis travel mechanism 70, the trapezoidal screw 622 is mounted on the screw base 621, and the trapezoidal screw 622 is self-locking. The nut 623 is mounted on the trapezoidal screw 622 and connected to the roller frame base 51 of the adaptive pressure roller assembly 50. The handwheel 624 is mounted on one end of the trapezoidal screw 622. Because the angle between the two mounting frames 20 does not need to be frequently adjusted in actual use, and the position of the two adaptive pressure roller assemblies 50 in the width direction of the mounting frames 20 does not need to be frequently adjusted, the screw mechanism 62 uses a handwheel 624, and the power source is manually operated, which is more economical and practical.

[0037] Two X-axis running mechanisms 70 are respectively mounted on the two mounting frames 20. Each X-axis running mechanism 70 is connected to the adaptive pressure roller assembly 50 and the Y-axis adjustment mechanism 60 on the mounting frame 20, and is used to drive the adaptive pressure roller assembly 50 and the Y-axis adjustment mechanism 60 to move along the length direction of the mounting frame 20. Figure 3 and Figure 4 As shown, each X-axis travel mechanism 70 includes an X-axis linear guide 71, a movable base 72, a drive motor 73, a gear 74, and a rack 75. The slide rail of the X-axis linear guide 71 is mounted on the bottom surface of the mounting frame 20 along the length direction, the movable base 72 is mounted on the slider of the X-axis linear guide 71, and the slide rail of the Y-axis linear guide 61 and the screw base 621 of the screw mechanism 62 are mounted on the movable base 72. The drive motor 73 is mounted on the movable base 72, the gear 74 is mounted on the output shaft of the drive motor 73, and the rack 75 is mounted on the side of the mounting frame 20 along the length direction and meshes with the gear 74. Among them, the X-axis travel mechanism 70 adopts a gear rack transmission, which has the advantages of smooth transmission and precise positioning.

[0038] The variable-angle adaptive scraping device further includes a control unit, which is used to control the operation of the drive motors 73 of the two X-axis walking mechanisms 70, so that the adaptive scraping device can realize automatic scraping operations.

[0039] In addition, according to the actual installation situation, the two X-axis walking mechanisms 70 can be arranged alternately to avoid collision between the adaptive pressure roller assembly 50 and the Y-axis adjustment mechanism 60 thereon, and the stroke of the drive motor 73 of the two X-axis walking mechanisms 70 also needs to be adjusted.

[0040] Before using this variable-angle adaptive scraping device for scraping, the angle between the two mounting frames 20 and the position of the two adaptive pressure roller assemblies 50 must be adjusted to match the shape of the sub-layer. To adjust the angle between the two mounting frames 20, first release the clamping member 43. Then, manually operate the handle 42 of the synchronous drive mechanism 40. The synchronous drive mechanism 40 drives the multiple lifting angle adjustment mechanisms 30 to operate synchronously, changing the angle between the two mounting frames 20. When the angle matches the sub-layer, stop operating the handle 42 and then tighten the clamping member 43, completing the adjustment. Next, adjust the position of the two adaptive pressure roller assemblies 50. To adjust, manually operate the handwheel 624 of the lead screw mechanism 62 of the Y-axis adjustment mechanism 60 to align the position of the adaptive pressure roller assembly 50 with the FSB surface to be scraped. Once adjusted to the desired position, release the handwheel 624, causing the trapezoidal lead screw 622 to self-lock.

[0041] Figure 6 It is a structural diagram of a variable-angle adaptive scraping device performing scraping operations.

[0042] like Figure 6 As shown, this variable-angle adaptive scraping device is installed on a dihedral workpiece scraping device. During operation, the main frame 10 is driven downward by the dihedral workpiece scraping device's lifting motor 3. The pressure rollers 55 of the two adaptive pressure roller assemblies 50 contact the FSB surface of the secondary component 1 supported by the dihedral workpiece scraping device's lower die 2. The pressing force of the pressure rollers 55 is adjusted by the lifting motor 3, which controls the amount of descent. The control unit then activates the drive motors 73 of the two X-axis travel mechanisms 70, driving the pressure rollers 55 of the two adaptive pressure roller assemblies 50 along their lengths. The pressure rollers 55 scrape the FSB. During this process, the pressure rollers 55, driven by springs 54, maintain contact with the FSB surface, ensuring a smooth and effective scraping process. Ultimately, the glue between the FSB and the secondary component is smoothed, and any bubbles in the glue are removed. The resulting glue maintains a uniform thickness within a specified thickness range, ensuring a smooth and accurate adhesion between the FSB and the secondary component.

[0043] Functions and Effects of the Embodiments

[0044] According to the variable-angle adaptive scraping device involved in this embodiment, a synchronous drive mechanism is used to drive multiple lifting angle adjustment mechanisms to adjust the angle between the two mounting frames. Each mounting frame is equipped with an adaptive pressure roller assembly and an X-axis walking mechanism that drives it to move. The pressure roller of the adaptive pressure roller assembly can always fit with the FSB. Therefore, this variable-angle adaptive scraping device can perform scraping operations on the FSB on sub-layer parts of different sizes and angles, and realize the scraping of the glue between the FSB and the sub-layer parts and the removal of bubbles in the glue. The thickness of the glue after scraping is uniform. The thickness is uniform and within the specified range, which ensures the adhesion effect and accuracy between the FSB and the sub-layer parts, and ensures the product quality; because a Y-axis adjustment mechanism is installed on each mounting frame, when the mounting frame is in different angle states, the Y-axis adjustment mechanism can adjust the position of the adaptive pressure roller assembly in the width direction of the mounting frame, so that the position of the adaptive pressure roller assembly matches the surface of the FSB to be scraped, ensuring that the folded corners of the FSB to be scraped are covered, so this variable-angle adaptive scraping device avoids the situation where the folded corners of the FSB are not scraped by the pressure roller, and ensures product quality.

[0045] The lifting angle adjustment mechanism includes a lifting mechanism, a lifting slider, and two connecting rods. The lifting mechanism drives the lifting slider up and down, and the lifting slider drives the two mounting frames to rotate via the two connecting rods, thereby changing the angle between the two mounting frames. The lifting mechanism preferably uses a worm gear screw lift, which has the advantages of high precision, compact structure, light weight, and a wide range of power sources. More importantly, it can be used in combination with multiple devices.

[0046] The synchronous drive mechanism consists of a synchronous shaft and a driver. The lifting mechanisms of multiple lifting angle adjustment mechanisms are linked via the synchronous shaft. The driver drives the synchronous shaft, which in turn drives the multiple lifting mechanisms to operate synchronously. Because the angle between the two mounting brackets does not require frequent adjustment, the driver is preferably a handle, using manual power as the source. A clamping member is configured on the synchronous shaft connected to the driver to meet high-precision positioning requirements.

[0047] The adaptive roller assembly consists of a roller stand, a roller frame, multiple mandrels, multiple springs, and a roller. The springs enable the roller's adaptive function, ensuring it maintains contact with the FSB surface during scraping. The roller is preferably made of polyurethane to protect the FSB surface.

[0048] The Y-axis adjustment mechanism utilizes a linear guide for guidance and a lead screw mechanism for adjustment, resulting in a simple structure and easy operation. Because the positioning requirements for the adaptive pressure roller assembly are relatively low, a trapezoidal lead screw is used for the lead screw mechanism, which self-locks once adjusted. Since the angle between the two pressure head mounting brackets does not require frequent adjustment, nor does the position of the two adaptive pressure roller assemblies, manual adjustment of the lead screw mechanism is more economical and practical.

[0049] The X-axis travel mechanism utilizes a drive motor, rack and pinion transmission, and an X-axis linear guide. The drive motor is controlled by a control unit, enabling automated scraping and leveling operations. This improves automation, significantly reduces labor intensity, and mitigates product quality issues caused by human error. The rack and pinion transmission offers the advantages of smooth transmission and precise positioning.

[0050] The above embodiments are preferred examples of the present invention and are not intended to limit the scope of protection of the present invention.
