Description

Technical Field

[0001] This utility model belongs to the field of marine oil engineering technology, and specifically relates to a slip block transport tool based on SPMT. Background Technology

[0002] In modern offshore oil engineering, slipway blocks, as crucial components for the onshore construction of large structures, play a vital role throughout the entire construction cycle. These slipway blocks are typically square or regular linear hexahedral structures, allowing for proper placement within the construction site and providing various possibilities for optimized transportation. However, current on-site transportation of slipway blocks primarily relies on lifting equipment such as crawler cranes to move them from one location to another. While effective in specific situations, this method becomes inefficient, resource-intensive, and environmentally impactful when transporting slipway blocks over long distances. First, due to the considerable distances between different slipways, using crawler cranes to transport slipway blocks requires covering a significant distance. In this context, a design where only one slipway block is lifted at a time is clearly inappropriate and inefficient. Crawler cranes are not only slow but can also handle only one slipway block per lifting operation, significantly extending transportation time. Furthermore, the operation of crawler cranes is complex, and the assembly and disassembly processes are cumbersome, increasing additional time costs and manpower requirements. This inefficient transportation method is particularly inconvenient for slide blocks that frequently change position.

[0003] Secondly, crawler cranes have high requirements for ground flatness during operation; any unevenness can affect their normal operation and even lead to safety hazards. At the same time, crawler cranes have relatively slow travel speeds, especially under non-ideal ground conditions, where their speed is further limited. More importantly, crawler cranes may cause serious damage to the ground during operation, particularly on sites paved with special materials or requiring preservation of integrity, which undoubtedly presents a significant challenge. Furthermore, due to their large size, crawler cranes have poor maneuverability in confined spaces, limiting their application in complex terrain conditions.

[0004] Furthermore, the transportation of slide blocks is also affected by natural factors such as wind speed and weather conditions. Adverse weather conditions not only affect the working efficiency of crawler cranes but also increase operational risks. For example, in strong winds, slide blocks at high altitudes are prone to swaying, increasing control difficulty and potential safety hazards. In addition, traditional transportation methods often require a large amount of auxiliary equipment and personnel, which not only increases operating costs but also adds complexity to management. To address these issues, this invention proposes a slide block transportation fixture based on a SPMT (Self-Propelled Modular Transporter), aiming to overcome many shortcomings of existing technologies. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a sliding block transportation fixture based on SPMT. By adopting SPMT, this fixture not only improves the transportation efficiency of the sliding blocks and reduces the probability of accidents, but also reduces the degree of damage to the ground.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a SPMT-based slide block transportation fixture, comprising: a top beam and column assembly, the first beam and column assembly comprising a first bottom beam and column assembly and two first span top columns, the two first span top columns being respectively inclined and fixed on both sides of the first bottom beam and column assembly, and the first ends of the two first span top columns being connected by a first fixed crossbeam.

[0007] The bottom beam assembly is fixed to the lower part of the top beam assembly by two vertical support columns and two second span top columns. The first end of the first span top column and the first end of the second span top column are both fixed to the top of the vertical support column, and the second end of the second span top column is fixed to the end face of the bottom beam assembly. The second span top column and the bottom beam assembly are placed at an angle.

[0008] Compared to existing technologies, the advantages of this utility model are as follows: The transport fixture proposed in this utility model, through cutting and welding, forms an overall structure with upper and lower layers. The upper layer's top beam and column assembly adopts a stable frame structure formed by the inclined arrangement of the first span top column and the first fixed crossbeam, which can effectively improve the bending stiffness and load-bearing capacity of the overall device, thereby better protecting the slide block from damage during transportation. Secondly, by connecting the bottom beam assembly to the top beam assembly at an angle, not only is the spatial layout of the structure optimized, but the stability of the entire fixture's center of gravity is also enhanced, avoiding the risk of overturning caused by the structural instability of traditional hoisting equipment. During transportation, two SPMTs are placed side by side, and the distance between the left and right ends of the two vehicles is controlled by the connecting blocks provided with the vehicles, so that the distance between the left and right ends of the two vehicles is consistent with the length of the bottom crossbeam, which facilitates the placement of the fixture. After confirmation, a forklift can be used to load the fixture onto the SPMT through the forklift loading and unloading holes reserved in the steel plate, and the fixture is fixed to the SPMT vehicle by the connecting bolts provided with the SPMT vehicle itself. The forklift then places the counterweight at the pre-reserved counterweight bearing area in the bottom frame and connects the corresponding locking device to the hook, suspending the necessary parts for lifting the slide block below. Once the vehicle reaches the vicinity of the slide block and secures it, the SPMT top plate can be used to lift the slide block off the ground and transport it to various locations within the site. This structural design facilitates quick docking with SPMT transport vehicles, improves loading and unloading efficiency, reduces manual intervention, and lowers operating costs.

[0009] The aforementioned transport fixture includes a first bottom beam-column assembly comprising multiple first horizontal beams, a first inclined beam, multiple first transverse columns, and multiple first crossbeams. The multiple first horizontal beams are disposed between the two first transverse columns, and the multiple first horizontal beams are arranged parallel to each other.

[0010] In the aforementioned transport fixture, the two first transverse columns and the two first horizontal beams form a parallelogram structure, and the first inclined beam is configured to connect a set of diagonal points of the parallelogram.

[0011] In the aforementioned transport fixture, the two vertical support columns are connected to the second span top column through multiple first crossbeams, and the two first crossbeams are arranged in parallel.

[0012] The aforementioned transport fixture includes a bottom beam assembly comprising multiple bottom horizontal beams and multiple bottom transverse beams, wherein the multiple bottom horizontal beams are disposed between two bottom transverse beams and the multiple bottom horizontal beams are arranged parallel to each other.

[0013] The aforementioned transport fixture, the bottom beam assembly further includes multiple first fixing stiffeners, and the bottom crossbeam is reinforced with the first fixing stiffeners.

[0014] The aforementioned transport fixture has a second fixing rib plate reinforcing the fixing points between the two vertical support columns and the bottom beam assembly.

[0015] The aforementioned transport fixture has a hook reinforcement plate below the top beam-column assembly.

[0016] The aforementioned transport fixture is fixed by welding between the bottom crossbeam, the number of vertical support columns, and the two first transverse columns.

[0017] The aforementioned transport fixture is fixed by welding the bottom horizontal beam and the bottom crossbeam, and the first horizontal beam, the first inclined beam, the first transverse column, and the first crossbeam are fixed by welding. Attached Figure Description

[0020] The reference numerals are as follows: 1000 First beam-column assembly, 1100 First bottom beam-column assembly, 1110 First horizontal beam, 1120 First inclined beam, 1130 First transverse column, 1140 First transverse beam, 1200 First span top column, 1300 First fixed transverse beam, 2000 Bottom beam assembly, 2100 Bottom horizontal beam, 2200 Bottom transverse beam, 2300 Vertical support column, 2400 Second span top column, 2500 First fixed stiffening plate, 2600 Second fixed stiffening plate, 2700 Hook stiffening plate. Detailed Implementation

[0021] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 2 This utility model provides a SPMT-based sliding block transport fixture, comprising: a top beam-column assembly 1000, the first beam-column assembly 1000 including a first bottom beam-column assembly 1100 and two first span top columns 1200, the two first span top columns 1200 being respectively inclinedly fixed to both sides of the first bottom beam-column assembly 1100, the first ends of the two first span top columns 1200 being connected by a first fixed crossbeam 1300; and a bottom beam assembly 2000, the bottom beam assembly 2000 being fixed to the lower side of the top beam-column assembly 1000 by two vertical support columns 2300 and two second span top columns 2400, the first ends of the first span top columns 1200 and the first ends of the second span top columns 2400 being fixed to the top of the vertical support columns 2300, the second ends of the second span top columns 2400 being fixed to the end face of the bottom beam assembly 2000, and the second span top columns 2400 being placed at an inclination with the bottom beam assembly 2000. The transport fixture 1000 proposed in this utility model, through cutting and welding, forms an overall structure with upper and lower layers. The upper layer's top beam-column assembly 1000 adopts a stable frame structure formed by an inclined arrangement of the first span top column 1200 and the first fixed crossbeam 1300, which can effectively improve the bending stiffness and load-bearing capacity of the overall device, thereby better protecting the slide blocks from damage during transportation. Secondly, by connecting the bottom beam assembly 2000 to the top beam assembly 1000 in a downward oblique manner, not only is the spatial layout of the structure optimized, but the stability of the center of gravity of the entire fixture 1000 is also enhanced, avoiding the risk of overturning caused by the structural instability of traditional hoisting equipment.

[0022] During transportation, two SPMTs are placed side by side. The spacing is controlled using the vehicle's connecting blocks, ensuring the distance between the left and right ends of the two vehicles matches the length of the bottom crossbeam 2200. This facilitates the placement of the design fixture. After confirmation, a forklift can load the fixture onto the SPMT through the forklift loading / unloading holes in the steel plate. The design fixture 2000 is then secured to the SPMT using the connecting bolts integrated into the SPMT itself. The forklift then places the counterweight at the pre-reserved counterweight bearing area in the bottom frame and connects the corresponding locking device to the hook, suspending the necessary parts for lifting the slide block below. Once the vehicle reaches the vicinity of the slide block and secures it, the slide block can be lifted off the ground by the SPMT's top plate and transported to various locations within the site. This structural design facilitates quick docking with the SPMT transport vehicle, solving the problem of unnecessary long-distance lifting and handling of slide blocks using crawler cranes in existing technologies, which is time-consuming and difficult. This significantly improves transportation efficiency, reduces the accident rate, minimizes slide block congestion, and protects the platform's integrity.

[0023] Furthermore, the first bottom beam-column assembly 1100 of the SPMT-based slide block transport fixture 1000 proposed in this application includes multiple first horizontal beams 1110, first inclined beams 1120, multiple first transverse columns 1130, and multiple first crossbeams 1140. The multiple first horizontal beams 1110 are disposed between two first transverse columns 1130, and are arranged parallel to each other. Of course, this application does not limit the specific structure between the first transverse columns 1130 and the first horizontal beams 1110. Preferably, the two first transverse columns 1130 and the two first horizontal beams 1110 form a parallelogram structure, and the first inclined beams 1120 are configured to connect a set of diagonal points of the parallelogram. The multiple parallel first horizontal beams 1110 form a uniformly distributed force system between the two first transverse columns 1130, which helps to disperse the vertical load from the top structure, prevent local stress concentration, and thus improve the safety and service life of the structure. Meanwhile, the first inclined beam 1120, acting as a diagonal support member, together with the first horizontal beam 1110 and the first transverse column 1130, forms a stable geometric structure, utilizing the principle of triangles to enhance the overall stability of the frame and prevent structural deformation or instability. The design of multiple first transverse beams 1140 not only provides additional lateral support for the first horizontal beam 1110 but also enhances the in-plane stiffness of the entire bottom beam-column assembly 1100, ensuring structural integrity under dynamic loads. By combining the first horizontal beam 1110 and the first transverse column 1130 into a parallelogram structure, higher structural stiffness and stability can be achieved without increasing material usage. Since parallelograms inherently possess a degree of variability, introducing the first inclined beam 1120 as a diagonal support effectively transforms it into two triangular structures, thereby utilizing the indeformable properties of triangles to enhance the overall structure's torsional resistance and load-bearing capacity. This design is particularly suitable for transport equipment 1000 subjected to complex directional loads, such as the lateral and longitudinal impact forces generated during SPMT operation due to ground undulations or acceleration / deceleration. Furthermore, the first inclined beam 1120 also serves as a guide and positioning element, ensuring that the spacing between the first horizontal beams 1110 remains constant and preventing structural displacement or misalignment caused by external forces. Ultimately, the technical effect of this claim is that it significantly improves the structural stability, torsional resistance, and load distribution uniformity of the first bottom beam-column assembly 1100, providing strong protection for safety and reliability during transportation.

[0024] Furthermore, the two vertical support columns 2300 are connected to the second span top column 2400 via multiple first crossbeams 1140, with the two first crossbeams 1140 arranged in parallel. The vertical support columns 2300 play a crucial role in transmitting and distributing loads from the top structure, while the second span top column 2400 is an important structure connecting the vertical support columns 2300 and the bottom beam assembly 2000. If the connection between the two is not strong enough, it is prone to loosening or even breaking under dynamic loads. Therefore, by setting multiple parallel first crossbeams 1140, not only can the connection stiffness between the vertical support columns 2300 and the second span top column 2400 be enhanced, but the shear resistance of the overall structure can also be effectively improved. In addition, the even distribution of the multiple first crossbeams 1140 also helps to rationally distribute the load and prevent structural failure caused by local overload. Furthermore, the bottom beam assembly 2000 proposed in this application includes multiple bottom horizontal beams 2100 and multiple bottom crossbeams 2200. The multiple bottom horizontal beams 2100 are arranged between two bottom crossbeams 2200 and are parallel to each other. As the basic load-bearing structure of the entire transport fixture 1000, the strength and stiffness of the bottom beam assembly 2000 directly determine the safety and reliability of the fixture 1000 during transportation. By setting multiple parallel bottom horizontal beams 2100 between two bottom crossbeams 2200, a densely distributed load-bearing network can be formed, making the load more evenly distributed on each stress point, thereby effectively preventing structural damage caused by local stress concentration. Of course, the bottom beam assembly 2000 proposed in this application also includes multiple first fixed stiffeners 2500, and the bottom crossbeams 2200 are reinforced with first fixed stiffeners 2500. During transportation, the bottom crossbeams 2200 must not only bear the vertical load from the slide block, but also resist the lateral and longitudinal impact forces caused by the movement of the transport vehicle. If the strength of the crossbeam structure is insufficient, problems such as bending and shear failure are likely to occur. Therefore, multiple first fixing stiffeners 2500 are added at the bottom crossbeam 2200, which can effectively improve the bending and shear resistance of the crossbeam through local reinforcement. Simultaneously, the introduction of stiffeners can also improve the connection stiffness between the crossbeam and other structural components (such as the bottom horizontal beam 2100), making the load transfer path clearer and more efficient. Furthermore, second fixing stiffeners 2600 are reinforced at the fixing points between the two vertical support columns 2300 and the bottom beam assembly 2000. As an important component connecting the top and bottom structures, the connection between the vertical support column 2300 and the bottom beam assembly 2000 is often one of the most critical stress nodes in the entire transport fixture 1000. If the strength of this connection is insufficient, it is very likely to become a weak point leading to structural failure. Therefore, the addition of second fixing stiffeners 2600 at the connection between the vertical support column 2300 and the bottom beam assembly 2000 can effectively enhance the tensile, shear, and bending resistance of this part. At the same time, the presence of stiffeners can also improve the stress distribution in the weld area and prevent weld cracking caused by stress concentration.

[0025] Furthermore, referring to Figure 2 A hook stiffener plate 2700 is provided below the top beam-column assembly 1000. As a key component connecting the lifting device or SPMT lifting mechanism, the hook stiffener plate 2700's location and structural strength directly affect the lifting efficiency and safety of the entire transport fixture 1000. By rationally arranging the hook stiffener plate 2700 below the top beam-column assembly 1000, a more stable and reliable connection between the lifting device or SPMT lifting mechanism and the fixture 1000 can be ensured, thereby reducing the risk of swaying and displacement during lifting. Of course, this application does not limit the structure of the hook stiffener plate 2700. Preferably, the hook stiffener plate 2700 has good versatility and interchangeability, facilitating compatibility with different models of SPMT equipment. Furthermore, the bottom crossbeam 2200, the several vertical support columns 2300, and the two first transverse columns 1130 are fixed together by welding. The bottom horizontal beam 2100 and bottom crossbeam 2200 are fixed by welding. The first horizontal beam 1110, first inclined beam 1120, first transverse column 1130, and first crossbeam 1140 are also fixed by welding. Welding, as a commonly used metal connection method, has advantages such as high connection strength, good sealing, and compact structure. In this invention, by using welding to fix the bottom crossbeam 2200 to the vertical support column 2300 and the first transverse column 1130, not only can seamless connection between components be achieved, but the tensile, shear, and bending resistance of the connection points can also be effectively improved. Furthermore, welded connections have good overall integrity, avoiding problems such as loosening and slippage that exist in bolted connections, thereby improving the structural stability and service life of the entire transport fixture 1000. In this invention, by fixing multiple key structural components by welding, the bending, shear, and torsional resistance of the entire transport fixture 1000 can be effectively improved, thereby enhancing its structural stability during transportation. In addition, welding can avoid problems such as loose bolts and gaps in the connection.

[0026] Furthermore, in actual use, the SPMT-based slide block transport fixture 1000 mentioned in this application is constructed by selecting steel sections, steel pipes, and steel plates with certain strength and specifications, and assembling them as described above. The connection style is not entirely fixed and can be modified. The steel plates on both sides of the bottom crossbeam 2200 can be added based on actual conditions to save materials, but welding quality and stability must be guaranteed. Using this fixture 1000 is convenient and quick; safety must be ensured during use, and forklift loading and unloading must comply with requirements to avoid risks arising from improper operation.
