Description

Technical Field

[0001] This invention relates to the technical field of large-scale marine engineering equipment, specifically to a method for low-altitude construction of modular non-slipway areas. Background Technology

[0002] Currently, ultra-large marine engineering equipment generally adopts the slipway construction and slip-shift loading mode, which requires laying long slipway blocks from the construction location to the front of the dock, resulting in low efficiency of slipway resource utilization. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a low-altitude construction method for the non-slide area of ​​the module that is conducive to improving the utilization rate of the slide, and at the same time, the construction scheme can enrich the structure of the module tooling.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A method for low-altitude construction of modular non-slide areas includes the following steps:

[0006] Two sets of modular transport vehicles arranged at intervals transport modular components from a non-slide area to a slide area. The modular components include blocks. The slide area has at least two slides, at least a portion of which is exposed in the gap between the two sets of modular transport vehicles. A lifting module is placed in the exposed area of ​​each slide. The lifting module is spaced apart from the block and includes a lifting device.

[0007] After transferring the module to the lifting device, the module transport vehicle drives away from the slide area;

[0008] The lifting device raises the block to a preset height and arranges two sets of support modules spaced apart from the raised block, such that at least two of the lifting modules are placed between the two sets of support modules. Each support module includes a support leg, and each support leg includes a boss and a support portion configured to support the block. The boss is provided on at least two opposite sides of the support portion.

[0009] The lifting device retracts to transfer the block to the support, connects the support and the retracted block, and the lifting module retracts from the slide after retraction. A functional structure is installed at the end of the block away from the support leg to form a tooling body. Each slide holds a set of drag slide blocks, and the drag slide blocks are spaced apart from the block.

[0010] A weight transfer device is placed on the side of the boss away from the block. At least two weight transfer devices are provided around the periphery of each support. The weight transfer device lifts the tooling body and installs the sliding shoe DSF on the drag track block. The sliding shoe DSF is spaced apart from the lifted block.

[0011] The weight transfer device retracts to transfer the tooling body to the slipper DSF, after which the support detaches from the assembly, and the retracted weight transfer device and the support module are removed.

[0012] In some possible implementations, the steps of loading and transferring the module components by the module transport vehicle include:

[0013] Two sets of first pad blocks are placed at intervals in the non-slide area;

[0014] The block assembly is placed in two sets of first pads. The block assembly also includes two lifting beams spaced apart. Each lifting beam is placed in a set of first pads. The lifting beam is connected to the block and protrudes from the opposite sides of the first pads along the arrangement direction of the two sets of first pads.

[0015] The module transport vehicle travels to the side of the protrusion of the lifting beam that is close to the first pad. The module transport vehicle includes a lifting component, which lifts the module component away from the first pad.

[0016] The lifting assembly descends to bring the lifting device into contact with the block, after which the lifting beam detaches from the block, and the module transport vehicle carries the detached lifting beam away from the slide area.

[0017] In some possible implementations, the step of placing the block assembly in the two sets of the first pads includes:

[0018] Each set of the first piers holds one of the aforementioned lifting beams;

[0019] The block is fixed to the end of the lifting beam away from the first pier.

[0020] In some possible implementations, the module includes a main body and two sets of columns spaced apart. The functional structure is mounted on the main body, and the columns are fixed to the main body and protrude from the main body relative to the ground. The lifting beam and the support portion are recessed relative to the end face of the column to form a slot. Each column is configured to be inserted into one of the slots, and the number of support legs and columns is the same.

[0021] The step of fixing the module to the lifting beam includes:

[0022] After inserting the column into the slot of the lifting beam, weld the two together.

[0023] After the lifting assembly returns to its original position, the solder is removed and the column is disengaged from the slot of the lifting beam;

[0024] Both the lifting module and the dragging slide block are positioned relative to the portion of the main body between the two sets of columns. When the lifting device falls back, the column moves toward the support to insert the column into the slot of the support, and then the two are welded together. After the solder between the support and the column is removed, the slot of the support disengages from the column.

[0025] In some possible implementations, the lifting beam includes a base and at least two spaced-apart support columns, the base being configured to rest on the first pier, the support columns protruding from the base away from the first pier, each of the support columns being configured to be disposed relative to a first pier, and the end face of the support column away from the base being recessed to form the slot.

[0026] In some possible implementations, at least two of the uprights are arranged at intervals to form a group, and at least two of the first pads are arranged at intervals to form a group, with the number of both the uprights and the support columns being the same.

[0027] In some possible implementations, the lifting module further includes a second pad, which is disposed between the lifting device and the slide.

[0028] In some possible implementations, the support module further includes a third pad, on which the support leg rests, the boss is spaced apart from the third pad, and the weight transfer device is located between the boss and the third pad.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] In this application, the modules are transported from the non-slide area to the slide area before the functional structure and DSF (Diverterless Supersonic Flip-Flap) are installed. This reduces the time the modules occupy the slide, thereby improving the utilization efficiency of the slide. Furthermore, during assembly, the coordinated use of the lifting device, support legs, and weight transfer device enriches the structure of the module tooling, allowing the functional structure to be installed on the top of the module.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0045] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are constructed to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. It should be noted that when an element is referred to as "fixed to" another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as "connected to" another element, it may be directly connected to the other element or there may be an intervening element.

[0046] One embodiment of this application provides a method for low-altitude construction of non-slide areas in modular blocks, comprising the following steps:

[0047] Step 1: Refer to Figure 1 Two sets of first pads 10 are placed at intervals in the non-slide area. Each set of first pads 10 holds a lifting beam 20. The lifting beam 20 protrudes from the opposite sides of the first pads 10 along the arrangement direction of the two sets of first pads 10.

[0048] In some embodiments, at least two first pads 10 spaced apart form a group, such that each group of first pads 10 can avoid at least three working areas of the lifting beam 20. For example, the first pads 10 can be formed by two independent blocks abutting against each other. For example, the blocks can be cement blocks. In this embodiment, two first pads 10 spaced apart form a group.

[0049] In some embodiments, the lifting beam 20 includes a base 21 and at least two spaced-apart support columns 22 (two support columns 22 are shown in the figure). The base 21 is configured to be placed on a first pad 10. The support columns 22 protrude from the base 21 away from the first pad 10. Each support column 22 is disposed relative to a first pad 10. Optionally, the end face of the support column 22 away from the base 21 is recessed to form a slot (shown in the figure).

[0050] In some embodiments, the lifting beam 20 may further include reinforcing ribs 23, with adjacent sides of the reinforcing ribs 23 adjacent to the support column 22 and the base 21. Each support column 22 is connected to two oppositely arranged reinforcing ribs 23 to improve the load-bearing strength of the lifting beam 20.

[0051] Step Two: Refer to Figure 2The module 30 is fixed to the end of the lifting beam 20 away from the first support 10 to form a module assembly (not shown in the figure), thereby completing the step of placing the module assembly on the two sets of first support 10s. That is, the module assembly includes the module 30 and two lifting beams 20 spaced apart. Each lifting beam 20 is placed on a set of first support 10s and is connected to the module 30. The lifting beams 20 can reduce the wear and tear on the module 30 during subsequent transportation and expand the working space under the module 30, thereby improving the ease of construction of the module tooling.

[0052] In some embodiments, the module 30 includes a main body 31 and two sets of spaced-apart columns 32. Exemplarily, the main body 31 may be primarily constructed of crossbeams and diagonal beams. The columns 32 are fixed to the main body 31 and protrude from the ground relative to the main body 31. Each column 32 is configured to insert into a slot. Therefore, in some embodiments, the columns 32 can be inserted into slots in the lifting beam 20 and then welded together to fix the module 30 to the lifting beam 20. Optionally, at least two spaced-apart columns 32 form a group, and the number of columns 32 and support columns 22 is the same, so that each column 32 can be inserted into a slot in each support column 22. The distribution of the columns 32 facilitates the balanced distribution of the weight of the module assembly, thereby improving the stability of the module assembly during transportation. Simultaneously, the structure of the module 30 also facilitates expanding the working space below the module 30.

[0053] In another embodiment, the block 30 and the lifting beam 20 can be fixed by direct welding or sleeve clamping, and the block 30 may consist only of the main body 31.

[0054] In another embodiment, the assembled modular components can be placed in two sets of first pads 10.

[0055] Step 3: Refer to Figures 2 to 4 Two sets of modular transport vehicles 40, spaced apart, transport modular components from a non-slide area to a slide area, which has at least two slides 50 (two slides are shown in the figure). For example, the modular transport vehicle 40 can be a self-propelled modular flatbed vehicle (SPMT), and at least a portion of the slide 50 is exposed through the gap between the two sets of modular transport vehicles 40. SPMT is open source, so the specific structure of the modular transport vehicle will not be described in detail.

[0056] Specifically, in some embodiments, the modular transport vehicle 40 includes a lifting assembly 41. For example, the lifting assembly 41 can be a pneumatic cylinder or a hydraulic cylinder. When the modular transport vehicle 40 travels to the side of the protrusion of the lifting beam 20 near the first support 10, the lifting assembly 41 lifts the module assembly away from the first support 10, thereby transporting the module assembly from the non-slide area to the slide area. The cooperation between the lifting assembly and the first support 10 facilitates the rapid loading of the module 30. Furthermore, the arrangement of each set of first support 10 increases the number of modular transport vehicles 40, thereby improving the transport stability of the module 30.

[0057] In another embodiment, modular components can be loaded into the module transport vehicle 40 in a non-slide area, thereby omitting steps one and two.

[0058] A lifting module 60 is placed in the exposed area of ​​each slide 50. The lifting module 60 is spaced apart from the block 30 and includes a lifting device 61. For example, the lifting device 61 can be a scissor lifting structure or a hydraulic lifting structure. In some embodiments, the lifting module 60 is disposed relative to a portion of the main body 31 between the two sets of columns 32.

[0059] In some embodiments, the lifting module 60 may further include a second support 62 disposed between the lifting device 61 and the slide rail 50. For example, the material of the second support 62 may be cement.

[0060] Step Four: Refer to Figures 3 to 5 The modular transport vehicle 40 transfers the module 30 to the lifting device 61 and then drives away from the slide area.

[0061] In some embodiments, specifically, the lifting assembly 41 falls back to allow the lifting device 61 to abut against the block 30, after which the lifting beam 20 detaches from the block 30, and the module transport vehicle 40 carries the detached lifting beam 20 away from the slide area. The module transport vehicle 40 can then return to the non-slide area for loading the next batch of blocks 30.

[0062] In some embodiments, after the lifting assembly 41 returns to its original position, the lifting beam 20 and the module 30 can be cut by laser removal of solder, and the column 32 can be disengaged from the slot of the lifting beam 20, thereby enabling the module transport vehicle 40 to complete the step of transferring the module 30. Transferring the module 30 by returning the lifting assembly 41 to its original position helps to reduce the working height and improve the convenience of operation.

[0063] In another embodiment, the weight of the assembly 30 can be transferred to the lifting device 61 by lifting the assembly 30 against the lifting device 61.

[0064] Step 5: Refer to Figure 6The lifting device 61 raises the block 30 to a preset height. It is understood that the lifting height of the lifting device 61 can be locked and fixed. Two sets of support modules 70 are arranged at intervals between the raised block 30, such that at least two lifting modules 60 are placed between the two sets of support modules 70. Each support module 70 includes a support leg 71, which includes a boss 712 and a support portion 711 configured to support the block 30. The number of support legs 71 and columns 32 is the same. The bosses 712 are at least located on opposite sides of the support portion 711. In this embodiment, the two spaced-apart support modules 70 form a group.

[0065] In some embodiments, the end face of the support relative to the column 32 is recessed to form a slot (not shown in the figure).

[0066] In some embodiments, the support module 70 further includes a third pad 72, on which the support leg 71 rests, and the boss 712 is spaced apart from the third pad 72. For example, the material of the third pad 72 may also be cement.

[0067] Step Six: Refer to Figure 6 and Figure 7 The lifting device 61 descends to transfer the block 30 to the support 711, connecting the support 711 and the descended block 30. In some embodiments, as the lifting device 61 descends, the column 32 moves toward the support 711 to insert the column 32 into the slot of the support 711 and then welds the two together. In other embodiments, the support 711 and the descended block 30 can be connected by pipe clamps or direct welding (omitting the slot).

[0068] After the lifting module 60 retracts from the slide rail 50, a functional structure 90 is installed at the end of the block 30 opposite to the support leg 71 to form a tooling body (not shown). For example, the functional structure 90 may include at least one of a drilling rig module, living quarters, operator's cab, or flare arm. Specifically, the functional structure 90 may be installed at the end of the body 31 opposite to the support leg 71. Each slide rail 50 holds a set of drag slide blocks 80, which are spaced apart from the block 30. In some embodiments, the drag slide blocks 80 are positioned relative to a portion of the body 31 between two sets of columns 32, and correspondingly, the drag slide blocks 80 are spaced apart from the body 31. For example, the drag slide blocks 80 may be cement blocks. It is understood that the order in which the drag slide blocks 80 are placed and the order in which the functional structure 90 is installed can be interchanged.

[0069] Step Seven: Refer to Figure 8 and Figure 9A weight transfer device 81 is placed on the side of the boss 712 away from the block 30. Optionally, the weight transfer device 81 is located between the boss 712 and the third pad 72. For example, the weight transfer device 81 can be a cylinder structure or a hydraulic cylinder structure. At least two weight transfer devices 81 are provided on the periphery of each support 711 (two weight transfer devices 81 are shown in the figure). The weight transfer device 81 lifts the tooling body and installs the slide shoe DSF (DECK SUPPORT FRAME) 91 on the drag track block 80. The slide shoe DSF 91 is spaced apart from the lifted block 30. The slide shoe DSF 91 is an open-source component, so its specific structure will not be described in detail. Since the drag track block 80 is set relative to the part of the main body 31 between the two sets of columns 32, the slide shoe DSF is also set relative to the part of the main body 31 between the two sets of columns 32. Specifically, the slide shoe DSF 91 is spaced apart from the lifted main body 31.

[0070] Step 8: Refer to Figures 8 to 10 The weight transfer device 81 falls back to transfer the tooling body to the slip shoe DSF91. Then the support 711 is detached from the block 30. The weight transfer device 81 and the support module 70 after falling back are removed, so that the tooling body and the slip shoe DSF91 together form the block tooling.

[0071] In some embodiments, after the solder between the support 711 and the column 32 is removed, the slot of the support 711 disengages from the column 32, thereby completing the disengagement of the support 711 from the assembly 30.

[0072] The modular tooling can be towed and loaded onto a ship for sea transport using a traction device (not shown in the figure).

[0073] In this application, the module 30 is transported from the non-slide area to the slide area before the functional structure 90 and the slide shoe DSF91 are installed. This reduces the time that the module 30 occupies the slide 50, thereby improving the utilization efficiency of the slide 50. In addition, during the assembly process, the coordinated operation of the lifting device 61, the support leg 71, and the weight transfer device 81 enriches the structure of the module tooling, allowing the functional structure 90 to be arranged on the top of the module 30.

[0074] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
