Description

Technical Field

[0001] This application relates to the technical field of installing pressure-bearing timber under ship tanks, and more particularly to an installation mechanism and method for installing pressure-bearing timber under ship tanks. Background Technology

[0002] In the construction of large ships and marine engineering equipment (such as LNG carriers), pressure timber is required between the tank structure and the hull structure to transfer loads, buffer vibrations, and insulate against heat conduction. A single piece of pressure timber can weigh between 300 kg and 600 kg, characterized by its heavy weight and high surface precision.

[0003] Currently, the installation of pressure timber mainly uses a hydraulic jacking vehicle in conjunction with a manual hoist: first, the pressure timber is lifted to the installation height, ropes are tied to the timber, and the hoist is used to pull it horizontally into the slot between the tank and the ship.

[0004] However, this method has the following drawbacks: First, the binding and dragging process can easily cause wear and scratches on the surface of the pressure-bearing wood, affecting its load-bearing capacity; second, it requires the cooperation of many people, making the operation cumbersome and the construction efficiency low; third, there are safety risks such as rope slippage and falling wood blocks when dragging the hoist; fourth, the installation space is narrow, and the lifting vehicle cannot be moved directly under the slot, increasing the difficulty of operation. Summary of the Invention

[0005] The purpose of this invention is to provide an installation mechanism and method for pressure-bearing timber in ship tanks, which can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] On the one hand, an installation mechanism for pressure-bearing timber in ship tanks is provided, which includes a first pulley assembly and a second pulley assembly; The first pulley assembly is detachably fixed to the end panel of the hull structure, and the second pulley assembly is placed on the panel of the tank structure; the end panel is located on one side of the slot for installing the pressure-bearing timber between the hull structure and the tank structure, and the panel is located at the bottom of the slot; Both the first pulley assembly and the second pulley assembly are provided with at least one rotatable rolling element, and the working surfaces of the rolling elements on the two pulley assemblies are at the same height; and When the pressure-bearing wood is inserted into the slot, the rolling element makes rolling contact with the lower end face of the pressure-bearing wood.

[0009] Preferably, the fastener is a bolt, used to pass through the hook portion and abut against the end panel of the hull structure.

[0010] Preferably, the second pulley assembly includes: A base for placement on the panel of the tank structure; and At least one second pulley is rotatably mounted on the base, and the rolling surface of the second pulley is higher than the upper surface of the base.

[0011] Preferably, the first pulley assembly and / or the second pulley assembly have multiple rolling elements, which are arranged side by side along the insertion direction of the pressure-bearing wood.

[0012] On the other hand, this disclosure also provides a method for installing pressure-bearing timber for ship tanks, which employs the installation mechanism described in any of the preceding claims, and includes the following steps: Step S1: Fix the first pulley assembly to the end panel of the hull structure, and place the second pulley assembly on the panel of the tank structure; Step S2: Use a lifting device to lift the pressure wood until its lower end surface is higher than the rolling surfaces of the first pulley assembly and the second pulley assembly; Step S3: Push the pressure wood horizontally so that the lower end face of the pressure wood slides into the slot between the hull structure and the tank structure under the rolling support of the first pulley assembly and the second pulley assembly; Step S4: Remove the first pulley assembly and the second pulley assembly, and tighten the fasteners of the pressure-bearing timber to complete the installation of the pressure-bearing timber.

[0013] Preferably, in step S1, the first pulley assembly is hooked to the end panel of the hull structure via a hook and locked to the end panel with bolts.

[0014] Preferably, in step S2, the lifting device is a hydraulic lifting trolley, and the pressure-bearing wood is placed on the hydraulic lifting trolley and moved to the side of the slot before being lifted.

[0015] Preferably, in step S3, when the pressure-bearing wood is pushed, the lower end face of the pressure-bearing wood simultaneously contacts the rolling elements of the first pulley assembly and the second pulley assembly.

[0016] Preferably, in step S4, the fastener is a bolt located at the lower end of the panel of the tank structure, and the bolt is tightened to press and fix the pressure wood in the slot.

[0017] The beneficial effects of this application are as follows: By setting up a first pulley assembly and a second pulley assembly, and installing rolling elements with working surfaces flush with the height of the two pulley assemblies, the sliding friction during the pushing of the pressure-bearing timber is transformed into rolling friction, significantly reducing the pushing resistance. The first pulley assembly adopts a wall-mounted structure, which, combined with the supporting structure of the second pulley assembly, can improve the transportation efficiency of pressure-bearing timber within a limited space.

[0018] Meanwhile, this solution is easy to operate, does not damage the pressure-bearing timber, is safe and reliable, and can be installed by a single person, which significantly improves construction efficiency and has good economic and social benefits. Attached Figure Description

[0022] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] Please see Figures 1 to 5 As shown, this embodiment provides an installation mechanism for pressure-bearing timber in ship tanks, which can improve the current problems of the pressure-bearing timber 600 between the tank structure 400 and the ship structure 300 being difficult to install, the easy wear and tear of the timber layer during the process of pulling it into the slot 500 by a hoist, the low overall construction efficiency, and the existence of safety risks.

[0026] Specifically, the installation mechanism for the pressure-bearing timber 600 of a ship tank provided in this disclosure includes a first pulley assembly 100 and a second pulley assembly 200. The first pulley assembly 100 is detachably fixed to the end panel 310 of the hull structure 300. Specifically, the end panel 310 of the hull structure 300 refers to a vertical or inclined plate located between the hull structure 300 and the tank structure 400, on one side of the slot 500 for installing the pressure-bearing timber 600. This plate is typically a steel structure with sufficient strength and rigidity to support the first pulley assembly 100 and the load it bears. The second pulley assembly 200 is placed on the panel 410 of the tank structure 400. The panel 410 is located at the bottom of the slot 500, typically a horizontal extension of the tank structure 400, and has a flat upper surface for stable placement of the second pulley assembly 200.

[0027] Furthermore, both the first pulley assembly 100 and the second pulley assembly 200 are provided with at least one rotatable rolling element. In this embodiment, the rolling element can be in the form of a rolling bearing, roller, or cylinder, as long as it can rotate freely around its own axis. The working surfaces of the rolling elements on the first pulley assembly 100 and the second pulley assembly 200 are at the same height. This means that when the first pulley assembly 100 and the second pulley assembly 200 are installed in their predetermined positions, the highest point of the rolling element on both sets of pulley assemblies is at the same horizontal level as the working surface in contact with the pressure-bearing wood 600. Therefore, it can be ensured that when the pressure-bearing wood 600 is pushed, its lower end face can simultaneously contact the rolling elements on both sets of pulley assemblies, obtaining stable rolling support.

[0028] Furthermore, when the pressure-bearing wood 600 is inserted into the slot 500, the rolling element makes rolling contact with the lower end face of the pressure-bearing wood 600. Specifically, as the pressure-bearing wood 600 is pushed into the slot 500, its lower end face first contacts the rolling elements on the first pulley assembly 100 and the second pulley assembly 200. As the pushing force continues to act, the rolling element rotates around its own axis, transforming the sliding friction between the pressure-bearing wood 600 and the hull structure 300 and the tank structure 400 into rolling friction, thereby significantly reducing the pushing resistance.

[0029] Understandably, by setting up the first pulley assembly 100 and the second pulley assembly 200, and by setting rolling elements with working surfaces flush with the height of the two pulley assemblies, the pressure wood 600 can obtain stable rolling support during insertion into the slot 500, effectively reducing pushing resistance and reducing wear on the surface of the pressure wood 600.

[0030] It should be noted that in some embodiments, the rolling element is not limited to pulleys, but may also be in the form of ball bearings, rollers, or omnidirectional balls. When an omnidirectional ball is used, the pressure-bearing wood 600 can not only be pushed in a single direction, but also adjusted at a certain angle, making it easier to make fine adjustments in confined spaces. In addition, the connection method between the first pulley assembly 100 and the end panel 310 of the hull structure 300 is not limited to bolt fixing, but may also be magnetic adsorption, snap-fit ​​connection, or vacuum suction cup, etc., which can be flexibly selected according to the on-site operating conditions.

[0031] In one embodiment, the first pulley assembly 100 includes a mounting base 110 and at least one first pulley 140. The upper part of the mounting base 110 is provided with a hook portion 120 for engaging with the end panel 310 of the hull structure 300. Specifically, the hook portion 120 is inverted U-shaped or L-shaped, and its opening size matches the thickness of the end panel 310, allowing it to be hooked from top to bottom onto the upper edge or side edge of the end panel 310. The hook portion 120 is provided with fasteners 130 for further tightening after engagement, preventing the first pulley assembly 100 from shifting or falling off during installation.

[0032] Furthermore, a first pulley 140 is rotatably mounted on the lower part of the fixed base 110. The first pulley 140 is connected to the fixed base 110 via an axle, and bearings can be installed at both ends of the axle to reduce rotational friction. There can be one or more first pulleys 140. When multiple first pulleys 140 are provided, they are arranged side by side along the insertion direction of the pressure wood 600 to form a continuous rolling support surface.

[0033] For example, in one specific implementation of this embodiment, the fixing base 110 is welded from steel plate, and the hook portion 120 is integrally formed with the fixing base 110 or connected by welding. The inner side of the hook portion 120 is provided with anti-slip texture or rubber pad to increase the friction between it and the end panel 310 and prevent slippage.

[0034] Understandably, the hook portion 120 allows the first pulley assembly 100 to be quickly attached to the end panel 310 of the hull structure 300, enabling rapid installation and removal. Simultaneously, the fasteners 130 ensure the stability of the first pulley assembly 100 during use, preventing displacement due to vibration or pushing force. The first pulley 140 is mounted on the lower part of the fixed base 110, forming good rolling contact with the lower end face of the pressure-bearing wood 600, further reducing pushing resistance.

[0035] It should be noted that in some embodiments, the shape of the hook portion 120 can be adapted to the specific structure of the end panel 310. For example, for end panels 310 with a larger thickness, the hook portion 120 can be designed as a structure with an adjustable opening width, and the opening size can be changed by adjusting the bolt to accommodate end panels 310 of different thicknesses. The fastener 130 is not limited to bolts, and can also adopt quick-locking structures such as quick clamps and eccentric cams to further improve the efficiency of disassembly and assembly.

[0036] In one embodiment, the fastener 130 is a bolt. Specifically, a threaded hole is provided on the hook portion 120, through which the bolt passes and extends in a direction perpendicular to the end panel 310. After the first pulley assembly 100 is attached to the end panel 310, the bolt is tightened so that the end of the bolt abuts against the surface of the end panel 310, thereby firmly fixing the first pulley assembly 100 to the end panel 310. Preferably, a flexible washer or a spherical contact head may be provided at the end of the bolt to avoid indentation or damage to the surface of the end panel 310. A handwheel or wing nut may be provided at the head of the bolt for easy manual operation, allowing tightening and loosening without the aid of tools.

[0037] For example, in one specific application of this embodiment, two bolts are provided on the hook portion 120, located on both sides of the hook portion 120 respectively, forming a two-point locking, which further improves the stability of the fixation. The two bolts can be tightened simultaneously, so that the first pulley assembly 100 is subjected to force evenly.

[0038] Understandably, bolts are used as fasteners 130 because they offer good detachability and facilitate reuse. At the same time, tightening the bolts against the end panel 310 effectively prevents displacement or wobbling of the first pulley assembly 100 during the pushing process, ensuring the stability of the rolling support.

[0039] In one embodiment, the second pulley assembly 200 includes a base 210 and at least one second pulley 220. The base 210 is used to place on the panel 410 of the tank structure 400, and its bottom surface is flat, enabling stable surface contact with the upper surface of the panel 410. The base 210 may be made of steel plate or cast iron, and has a certain weight and a low center of gravity to ensure stability after placement.

[0040] Furthermore, a second pulley 220 is rotatably mounted on the base 210. The second pulley 220 is connected to the base 210 via an axle, with bearings at both ends of the axle to reduce rotational friction. The rolling surface of the second pulley 220 is higher than the upper surface of the base 210, meaning the top of the second pulley 220 protrudes beyond the upper surface of the base 210. This ensures that when the lower end face of the pressure wood 600 contacts the second pulley 220, a certain gap is maintained between the pressure wood 600 and the base 210, preventing interference from the base 210 in pushing the pressure wood 600.

[0041] In one specific implementation of this embodiment, the base 210 is provided with two second pulleys 220, which are arranged side by side along the insertion direction of the pressure wood 600. The rolling surfaces of the two second pulleys 220 are at the same height, forming a continuous rolling support surface together.

[0042] It should be noted that an anti-slip pad, such as a rubber pad or a felt pad, can be provided on the bottom of the base 210 to increase the friction between it and the panel 410 and prevent the second pulley assembly 200 from sliding during the pushing process. The anti-slip pad also acts as a cushion to prevent the base 210 from damaging the surface of the panel 410.

[0043] Understandably, the base 210 provides a stable support foundation, allowing the second pulley assembly 200 to be placed smoothly on the panel 410 of the tank structure 400; the rolling surface of the second pulley 220 is higher than the upper surface of the base 210, ensuring that the pressure wood 600 only contacts the pulley when pushed, avoiding interference from the base 210; the second pulley assembly 200 does not need to be fixedly connected to the panel 410, but only relies on gravity to maintain its position, making installation and removal extremely convenient, and it can be flexibly moved as the installation position of the pressure wood 600 changes.

[0044] In one embodiment, the first pulley assembly 100 contains multiple rolling elements arranged side-by-side along the insertion direction of the pressure-bearing wood 600. Specifically, the first pulley assembly 100 contains two, three, or more first pulleys 140, which are arranged sequentially along the direction in which the pressure-bearing wood 600 is inserted into the slot 500. The axles of each first pulley 140 are parallel to each other, and the rolling surfaces of each first pulley 140 are at the same height, forming a continuous rolling support belt. Similarly, the second pulley assembly 200 can also contain multiple rolling elements. When the second pulley assembly 200 contains multiple second pulleys 220, the multiple second pulleys 220 are also arranged side-by-side along the insertion direction of the pressure-bearing wood 600, forming a continuous rolling support belt.

[0045] Understandably, the arrangement of multiple rolling elements allows the lower end face of the pressure wood 600 to contact multiple rolling elements simultaneously, dispersing the contact pressure, reducing wear on individual rolling elements, and improving the stability of the rolling support. When the pressure wood 600 is long or heavy, multiple rolling elements can provide more even support, preventing the pressure wood 600 from tilting or jamming during pushing.

[0046] Please see Figure 5 As shown, on the other hand, this disclosure also provides a method for installing pressure-bearing timber 600 for ship tanks, which can employ any of the installation mechanisms described in the above embodiments.

[0047] Specifically, the installation method for the pressure-bearing timber 600 of a ship tank provided in this disclosure may include the following steps.

[0048] First, in step S10, the first pulley assembly 100 is fixed to the end panel 310 of the hull structure 300, and the second pulley assembly 200 is placed on the panel 410 of the tank structure 400. Specifically, the operator first hooks the hook portion 120 of the first pulley assembly 100 onto the upper edge of the end panel 310, and then tightens the fastener 130 (such as a bolt) to securely connect the first pulley assembly 100 to the end panel 310. Subsequently, the base 210 of the second pulley assembly 200 is placed stably on the panel 410 of the tank structure 400, ensuring that the position of the second pulley assembly 200 corresponds to that of the first pulley assembly 100, and that the rolling surfaces of the two pulley assemblies are flush.

[0049] It should be noted that in step S10, the operator can adjust the placement of the second pulley assembly 200 according to the installation position of the pressure-bearing wood 600, so that it is aligned with the rolling element of the first pulley assembly 100 to form a continuous rolling support path.

[0050] Then, step S20 is executed, using the lifting device 700 to lift the pressure wood 600 until its lower end face is higher than the rolling surfaces of the first pulley assembly 100 and the second pulley assembly 200. Specifically, the pressure wood 600 is placed on the lifting device 700 (such as a hydraulic lifting trolley), and the lifting device 700 is operated to slowly raise the pressure wood 600. When the height of the lower end face of the pressure wood 600 exceeds the highest point of the rolling elements of the two sets of pulley assemblies, the lifting is stopped. At this time, a gap of about 5-10 mm is maintained between the lower end face of the pressure wood 600 and the rolling elements to facilitate subsequent horizontal pushing operations.

[0051] Furthermore, in step S30, the pressure-bearing wooden block 600 is pushed horizontally, causing its lower end face to slide into the slot 500 between the hull structure 300 and the tank structure 400 under the rolling support of the first pulley assembly 100 and the second pulley assembly 200. The operator applies a horizontal thrust from the side of the pressure-bearing wooden block 600, pushing it towards the slot 500. When the pressure-bearing wooden block 600 moves above the rolling element, its lower end face contacts the rolling element. Since the rolling element can rotate freely, the sliding friction of the pressure-bearing wooden block 600 is converted into rolling friction, significantly reducing the pushing resistance. The operator can then easily push the pressure-bearing wooden block 600 into the predetermined position within the slot 500.

[0052] Finally, step S40 is executed to remove the first pulley assembly 100 and the second pulley assembly 200, and to tighten the fasteners of the pressure-bearing timber 600, thus completing the installation of the pressure-bearing timber 600. Specifically, after the pressure-bearing timber 600 is fully inserted into the slot 500, the second pulley assembly 200 is first removed and taken off the panel 410; then the fasteners 130 on the first pulley assembly 100 are loosened, and the first pulley assembly 100 is removed from the end panel 310. Finally, the bolts or other fasteners located at the lower end of the panel 410 of the tank structure 400 are tightened to secure the pressure-bearing timber 600 within the slot 500.

[0053] Understandably, this method achieves rapid, safe, and non-destructive installation of the pressure timber 600 through a process of first installing the pulley assembly, then lifting the pressure timber 600, then pushing it horizontally, and finally removing the fixing devices. Throughout the process, there is no need to tie ropes to the pressure timber 600 or use a hoist for dragging, thus avoiding surface damage to the pressure timber 600 and reducing labor intensity and safety risks.

[0054] In one embodiment, step S10 specifically includes: the first pulley assembly 100 is hooked onto the end panel 310 of the hull structure 300 via a hook portion 120, and then locked and fixed to the end panel 310 with bolts. During operation, the operator first hooks the hook portion 120 of the first pulley assembly 100 onto the upper edge of the end panel 310 from top to bottom. Since the opening size of the hook portion 120 matches the thickness of the end panel 310, after hooking, the first pulley assembly 100 naturally droops under gravity, and the inner side of the hook portion 120 is in contact with the surface of the end panel 310. Subsequently, the operator tightens the bolts provided on the hook portion 120, so that the end of the bolt abuts against the surface of the end panel 310. The tightening force of the bolts is transmitted through the hook portion 120, firmly clamping the first pulley assembly 100 onto the end panel 310.

[0055] In one embodiment, the lifting device 700 used in step S20 is a hydraulic lifting trolley. The hydraulic lifting trolley has a frame, hydraulic jacks, and wheels, and can carry the pressure-bearing timber 600 and perform movement and lifting operations.

[0056] In practice, the operator first places the pressure-bearing timber 600 on the pallet of the hydraulic jacking trolley, ensuring its center of gravity is stable. Then, the hydraulic jacking trolley is moved to the side of the slot 500, aligning the length of the pressure-bearing timber 600 with the opening direction of the slot 500. Next, the hydraulic handle of the hydraulic jacking trolley is operated, causing the hydraulic jacks to slowly rise, with the pallet lifting the pressure-bearing timber 600. The operator observes the relative height between the lower end face of the pressure-bearing timber 600 and the rolling elements of the two sets of pulley assemblies. Lifting is stopped when the lower end face of the pressure-bearing timber 600 is approximately 5-10mm higher than the working surface of the rolling elements.

[0057] It is important to note that the hydraulic jacking trolley has a self-locking function, which maintains the jacking height after operation stops, ensuring that the pressure-bearing timber 600 will not fall accidentally during horizontal pushing. After pushing the pressure-bearing timber 600, operate the hydraulic jacking trolley to release pressure, causing the pallet to lower, and then the trolley can be moved away.

[0058] In one embodiment, during step S30, when the pressure-bearing wood 600 is pushed, the lower end face of the pressure-bearing wood 600 simultaneously contacts the rolling elements of the first pulley assembly 100 and the second pulley assembly 200.

[0059] Specifically, as the pressure-bearing wood 600 is pushed into the slot 500, its lower end face first contacts the first pulley 140 on the first pulley assembly 100. With the continued pushing force, the pressure-bearing wood 600 continues to move forward, and its lower end face gradually contacts the second pulley 220 on the second pulley assembly 200. Since the working surfaces of the first pulley 140 and the second pulley 220 are at the same height, when the pressure-bearing wood 600 has a sufficient length to pass over the first pulley assembly 100, the lower end face of the pressure-bearing wood 600 will simultaneously contact at least one first pulley 140 and at least one second pulley 220. At this time, the weight of the pressure-bearing wood 600 is evenly distributed across multiple rolling elements through its lower end face, and each rolling element shares the load and rotates around its own axis. Because the rolling elements and the lower end face of the pressure-bearing wood 600 are in rolling contact, the friction is minimal, and the operator only needs to apply a very small horizontal pushing force to propel the pressure-bearing wood 600 forward smoothly.

[0060] It should be noted that for longer load-bearing timber 600, a third or fourth pulley assembly can be added along the pushing path to form multiple sets of rolling supports, further distributing the load and making the pushing process more stable. For wider load-bearing timber 600, multiple sets of second pulley assemblies 200 can be arranged side by side to form a wider rolling support surface, preventing the load-bearing timber 600 from tilting during the pushing process.

[0061] In one embodiment, the fixing element in step S40 is a bolt located at the lower end of the panel 410 of the tank structure 400. Specifically, the lower end of the panel 410 of the tank structure 400 is pre-set with multiple threaded holes or through holes for use with fixing bolts. After the pressure wood 600 is pushed into the predetermined position in the slot 500, the operator passes the fixing bolt through the through hole on the panel 410 and screws it into the pre-set threaded hole on the pressure wood 600, or directly presses the fixing bolt against the surface of the pressure wood 600, so that the pressure wood 600 is pressed and fixed in the slot 500.

[0062] It is important to note that when tightening the fixing bolts, the operator should use a diagonal tightening sequence to ensure even stress distribution on the load-bearing timber 600 and avoid deformation or stress concentration caused by excessive tightening in certain areas. The tightening torque should be determined based on the material properties of the load-bearing timber 600 and the specifications of the fixing bolts, and is generally controlled within the range of 30-50 N·m.

[0063] In summary, the present invention provides an installation mechanism and method for pressure-bearing timber in ship tanks. By setting up a first pulley assembly 100 and a second pulley assembly 200, and installing rolling elements with working surfaces flush with the height of the two pulley assemblies, the sliding friction during the pushing process of the pressure-bearing timber 600 is transformed into rolling friction, significantly reducing the pushing resistance. Furthermore, this technical solution is simple to operate, causes no damage to the pressure-bearing timber 600, is safe and reliable, and can be installed by a single person, significantly improving construction efficiency and demonstrating good economic and social benefits.
