Each example is provided to explain the invention and not to limit it. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made to the invention without departing from the scope or spirit thereof. For example, a feature shown or described as part of one embodiment may be used with another embodiment to produce yet another embodiment. Therefore, the invention is intended to cover these modifications and variations that fall within the scope of the appended claims and their equivalents.

[0024] As used herein, the terms “first,” “second,” and “third” are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of the individual components.

[0025] An LNG storage tank includes an inner wall (not shown) and wall panels (not shown), with a sandwich layer formed between the inner wall and the wall panels, the sandwich layer having a certain space. The construction device for the tank sandwich layer of the present invention allows construction personnel to perform construction operations within the confined space of this sandwich layer.

[0026] Figure 1 The structure of an embodiment of the construction apparatus for the storage tank interlayer of the present invention is shown. For example... Figure 1 As shown, the construction device of the present invention includes a base assembly 100, an extension assembly 200, a support platform 300, and a movement assembly 400. The base assembly 100, extension assembly 200, and support platform 300 are located within a mezzanine; the movement assembly 400 is located on top of a wall panel and cooperates with the wall panel. The support platform 300 can accommodate construction personnel for their work. A protective frame 500 is welded to the support platform 300, providing protection for construction personnel who squat and step on the top of the platform.

[0027] The construction device of the present invention includes a first side 11 and a second side 12 opposite to each other, wherein the first side 11 is close to the wall panel and the second side 12 is close to the inner wall, and the motion component 400 is located on the first side 11 to dock with the wall panel.

[0028] The extension assembly 200 includes an extension mechanism 210, and the base assembly 100 includes a base plate 110 and an extension engagement mechanism 120. The extension mechanism 210 and the extension engagement mechanism 120 cooperate to allow the extension mechanism 210 to move relative to the extension engagement mechanism 120 in the vertical YY direction (i.e., the height direction). The support platform 300 is fixed to the extension mechanism 210 and can move with the extension mechanism 210.

[0029] The motion component 400 is disposed on the support platform 300. The motion component 400 cooperates with the top of the wall panel and can move along the top of the wall panel to drive the support platform 300 to move horizontally along the wall panel.

[0030] The base assembly 100 also includes a first sliding mechanism 130 and a second sliding mechanism 140 disposed on the extension mating mechanism 120. The first sliding mechanism 130 is disposed on the first side 11 of the construction device and is used to abut against the wall panel. The second sliding mechanism 140 is disposed on the second side 12 of the construction device and is used to abut against the inner wall.

[0031] The construction device for the storage tank interlayer of the present invention can be installed inside the storage tank interlayer. The moving component 400 realizes the horizontal movement along the wall panel. The first sliding mechanism 130 and the second sliding mechanism 140 respectively adhere to the wall panel and the inner wall to form a stable support, thereby improving the overall stability of the device's movement. When the height of the top of the wall panel changes and the construction position needs to be adjusted, the first sliding mechanism 130 and the second sliding mechanism 140 can fix the position of the base component 100 in the vertical YY direction. The relative movement between the extension mechanism 210 and the extension cooperation mechanism 120 drives the support platform 300 to move, thereby changing the height of the support platform 300, which facilitates the adjustment of the construction position according to the height of the top of the wall panel.

[0032] In one embodiment, the motion assembly 400 includes a motion mechanism 410 and a guide frame 420. The guide frame 420 is fixed to the support platform 300 and defines a receiving groove 421 with its opening facing downwards, capable of accommodating at least a portion of the top of the wall panel. The motion mechanism 410 is movably disposed within the receiving groove 421. Figure 1 and Figure 2 As shown, the guide frame 420 includes two opposing side frames 422, which cooperate with the wall panel and have a guiding function, so that the motion mechanism 410 can only move along the extension direction of the top of the wall panel.

[0033] The motion mechanism 410 includes a drive element 411 and multiple track wheels. The track wheels are spaced apart within the receiving groove 421. The track wheels are movably connected to the guide frame 420. The drive element 411 connects to the multiple track wheels to drive them to rotate relative to the guide frame 420. The track wheels move on top of the wall panel, thereby moving the entire construction device along the wall panel. The multiple track wheels improve the stability of movement and prevent tipping.

[0034] In one specific embodiment, there are two track wheels, namely a first track wheel 412 and a second track wheel 413. The central axes of both the first track wheel 412 and the second track wheel 413 are on a first direction AA. The first direction AA is perpendicular to the vertical direction YY and perpendicular to the wall panel and the inner wall. The output end of the drive unit 411 is connected to the first track wheel 412 to drive its rotation. The drive unit 411 can be a servo motor. The first track wheel 412 and the second track wheel 413 are connected to drive their rotation. By using a servo motor to drive the first track wheel 412 to rotate, and the first track wheel 412 driving the second track wheel 413 to rotate, a synergistic advantage is formed in terms of structural stability, motion accuracy, spatial adaptability, and control efficiency, making it suitable for achieving precise and stable movement in tank construction operations within confined spaces.

[0035] like Figure 4 As shown, specifically, a partition plate 430 is fixedly disposed within the receiving groove 421 of the guide frame 420. The partition plate 430 is disposed along the first direction AA. The motion mechanism 410 also includes a first pulley 414, a second pulley 415, a third pulley 416, a first transmission belt 417, and a second transmission belt 418. The first end of the first track wheel 412 passes through the partition plate 430 and is fixedly connected to the first pulley 414, and the second end of the first track wheel 412 is movably connected to the guide frame 420. The first end of the second track wheel 413 passes through the partition plate 430 and is fixedly connected to the second pulley 415, and the second end of the second track wheel 413 is movably connected to the guide frame 420. The output end of the drive member 411 is fixedly connected to the third pulley 416. The first transmission belt 417 is drivingly connected between the third pulley 416 and the first pulley 414, and the second transmission belt 418 is drivingly connected between the first pulley 414 and the second pulley 415. The partition plate 430 can support the first track wheel 412 and the second track wheel 413.

[0036] refer to Figure 2 A fixing plate 440 is fixedly provided between the partition plate 430 and the side frame 422. The driving component 411 is fixed on the fixing plate 440 to avoid interference between the driving component 411 and the first track wheel 412 and the second track wheel 413.

[0037] Combination Figure 1 and Figure 5 In one embodiment, the extension mechanism 210 includes a plurality of extension posts 211, and the extension mating mechanism 120 includes a plurality of mating sleeve posts 121. Both the extension posts 211 and the mating sleeve posts 121 extend in the vertical direction YY. The number of extension posts 211 and mating sleeve posts 121 are the same. Figure 5 and Figure 6 As shown, there are four extension columns 211 and four mating sleeve columns 121. The four mating sleeve columns 121 are fixed to the four corners of the base plate 110, with two mating sleeve columns 121 located on the first side 11 and the remaining two on the second side 12. The multiple mating sleeve columns 121 are fixed to the base plate 110. The design of multiple extension columns 211 and mating sleeve columns 121 evenly distributes the weight and force of the bearing platform 300, enhancing the stability of the entire structure. Simultaneously, the mating sleeve columns 121, fixed to the base plate 110, provide reliable support for the extension columns 211, ensuring the bearing platform 300 remains stable at different heights, can withstand large loads, and is suitable for carrying heavy equipment or personnel.

[0038] A guide groove 122 is provided on the sleeve 121, and the guide groove 122 extends in the vertical YY direction. For example... Figure 5 and Figure 6 As shown, the cross-sections of the extension column 211 and the guide groove 122 are T-shaped. At least a portion of the extension column 211 is housed within the guide groove 122. The extension column 211 can move along the extension direction of the guide groove 122, thereby changing the position of the support platform 300 relative to the base plate 110. This allows the support platform 300 to flexibly adjust its position according to the height of the top of the wall panel. The guide groove 122 on the sleeve column 121 provides a clear movement trajectory for the extension column 211, ensuring its stability during movement and preventing deviation or swaying, thus achieving precise positioning of the support platform 300.

[0039] like Figure 1 As shown, in one embodiment, the base assembly 100 further includes a first drive mechanism 150. The output end of the first drive mechanism 150 is fixed to the top surface of the base plate 110, and the fixed end of the first drive mechanism 150 is fixed to the bottom of the extension column 211. The first drive mechanism 150 can extend and retract in the vertical direction YY, thereby driving the extension column 211 to move relative to the mating sleeve column 121 in the vertical direction YY. The first drive mechanism 150 can be an electric cylinder, eliminating the need for manual adjustment of the position of the extension column 211, significantly reducing labor costs and operational intensity.

[0040] like Figure 5As shown, in one embodiment, the extension assembly 200 further includes a plurality of connecting rods 220, which are arranged along a first direction AA and used to connect two adjacent extension posts 211. The plurality of connecting rods 220 are spaced apart in the vertical direction YY. Figure 5 In the illustrated embodiment, two connecting rods 220 are arranged on the same horizontal plane, which can be regarded as a set of connecting rods 220; as Figure 1 As shown, there are six sets of connecting rods 220 in the vertical YY direction. The connecting rods 220 facilitate climbing by construction workers.

[0041] Continue to refer to Figure 5 A support rod 230 is fixed between a set of connecting rods 220. The support rod 230 is arranged along the second direction. The connecting rods 220 and the support rod 230 can increase the overall stability of the extension column 211.

[0042] In one embodiment, the first sliding mechanism 130 includes a plurality of first sliding rollers 131, which are spaced apart on the mating sleeves 121 located on the first side 11. The second sliding mechanism 140 includes a plurality of second sliding rollers 141, which are spaced apart on the mating sleeves 121 located on the second side 12. As the two sets of track wheels rotate along the top of the wall panel, the cooperation of the plurality of first sliding rollers 131 and second sliding rollers 141 enables the construction device to move autonomously.

[0043] Combination Figure 3 and Figure 6 As shown, in one embodiment, the base assembly 100 further includes a plurality of connecting brackets 160, which connect two mating sleeve posts 121 located on the first side 11 and two mating sleeve posts 121 located on the second side 12, and the connecting brackets 160 are arranged along a second direction BB. The second direction BB is perpendicular to the first direction AA and the vertical direction YY.

[0044] The construction device also includes a movable mechanism 600 disposed on a connecting frame 160 located on the second side 12. The movable mechanism 600 is movable relative to the connecting frame 160 in a first direction AA. During the movement of the construction device, the movable mechanism 600 can conform to the inner wall of the building and roll along the inner wall. It works in conjunction with the first sliding mechanism 130 and the second sliding mechanism 140 to conform to the wall panel and form support, thereby increasing the stability of the overall equipment during movement, providing support to the inner wall, and increasing the stability of the movement.

[0045] If the first sliding roller 131 and the wall panel are not tightly attached and / or the second sliding roller 141 and the wall panel are not tightly attached, the movable mechanism 600 moves toward the inner wall in the first direction AA until the first sliding roller 131 on the first side 11 abuts against the wall panel, and at the same time the movable mechanism 600 abuts against the inner wall, so that the base assembly 100 can be relatively fixed, thus adjusting the height of the bearing platform 300.

[0046] Combination Figure 3 and Figure 6 Specifically, the movable mechanism 600 includes a roller frame 610, a movable roller 620, a concave seat 630, and a second drive mechanism 640. The concave seat 630 is fixed to the mating sleeve 121, and the second drive mechanism 640 is mounted on the concave seat 630. The output end of the second drive mechanism 640 is fixedly connected to the roller frame 610, and the movable roller 620 is rotatably mounted on the roller frame 610. The second drive mechanism 640 can drive the roller frame 610 to move in the first direction AA, thereby moving closer to or away from the inner wall. (Reference) Figure 6 There is a certain distance between the left side of the second drive mechanism 640 and the right side of the support rod 230 to avoid interference. The second drive mechanism 640 can be an electric cylinder.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the construction device of the present invention further includes a controller 700. The controller 700 is fixed to the top of the support platform 300. The controller 700 is electrically connected to the drive component 411 for easy relocation during construction. The controller 700 is electrically connected to the first drive mechanism 150 for easy adjustment of the height of the construction device. The controller 700 is electrically connected to the second drive mechanism 640 to increase stability during movement.

[0048] The working principle and process of the construction device of the present invention are described in detail below with reference to the above embodiments: When using the construction device of the present invention, firstly, the height of the bearing platform 300 is adjusted according to the height of the wall panel, and the receiving groove 421 is located directly above the wall panel. The first track wheel 412 and the second track wheel 413 press on the top of the wall panel, and the construction personnel squat on the top of the platform. The protective frame 500 can play a protective role.

[0049] When the current section of construction is completed and needs to be moved, the drive unit 411 is activated. The drive unit 411 drives the first track wheel 412 to rotate through the third pulley 416, the first transmission belt 417, and the first pulley 414. The first track wheel 412 drives the second track wheel 413 to rotate through the first pulley 414, the second pulley 415, and the second transmission belt 418. The two sets of track wheels rotate along the top of the wall panel. With the cooperation of the first sliding roller 131 and the second sliding roller 141, the device can move autonomously.

[0050] The connecting rods 220 between the extension columns 211 facilitate climbing by construction workers. The height of the bearing platform 300 can be adjusted according to the height of the wall panel. The first drive mechanism 150 is activated, and the first drive mechanism 150 can extend or retract, thereby pushing the extension column 211 to slide up and down along the mating sleeve column 121, thereby adjusting the height of the bearing platform 300.

[0051] The connecting rod 220 and the support rod 230 can increase the overall stability of the extension column 211. During the displacement process, the second drive mechanism 640 on the concave seat of the construction device of the present invention extends outward, pushing the roller frame 610 together with the movable roller 620 to fit against the inner wall of the building. The movable roller 620 rolls against the inner wall of the building, and cooperates with the sliding roller to fit against the sandwich panel to form support, thereby increasing the stability of the device during overall displacement.

[0052] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any variations and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the invention, fall within the protection scope defined by the claims of the present invention.
