Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, and in particular to a track beam structure for the shipment of HDPE pipelines. Background Technology

[0002] HDPE (High Density Polyethylene) pipes have excellent corrosion resistance, resisting the erosion of salt and other chemicals in seawater, and are therefore commonly used for seawater transportation. When HDPE pipes are used as water intake pipes in seawater cooling systems, large HDPE pipes (diameter ≥ 3000 mm; weight ≥ 1 t) are often required. Before these HDPE pipes are introduced into the water, ballast blocks need to be placed on a transport trolley on land. Then, the HDPE pipes are connected to the ballast blocks, and the transport trolley moves along the transport track to bring the HDPE pipes into the sea.

[0003] Currently, the commonly used track beam structure is mostly a conventional track with an I-beam cross-section. The concave wheels of the trolley roll on the track, thus moving the transport trolley. However, the existing prefabricated track beams have a single size, which cannot fully meet the different needs of on-site construction for the wheel size of the transport trolley. In addition, after the trolley enters the water, it is subject to lateral loads from wind and waves. Using prefabricated track beams can easily cause the trolley wheels to collide with the track beam and be damaged, shortening the service life of the trolley. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing track beams, such as their limited size, poor construction flexibility, and the tendency for the track to collide with the wheels of the transport trolley after entering the water, thereby damaging the transport trolley. This invention provides a track beam structure for transporting HDPE pipes.

[0005] In a first aspect, this utility model provides a track beam structure for transporting HDPE pipes, comprising a plurality of unit sections connected in sequence. Each unit section includes a foundation and a track fixedly connected to the top of the foundation. The track is a groove-shaped structure with its opening facing upwards. The groove of the track is for the wheels of the transport trolley to be inserted. The width of the groove of the track on land is d, and the width of the groove of the track underwater is D, where d < D.

[0006] The track beam structure for transporting HDPE pipes provided by this utility model is a groove-shaped structure with the track opening facing upwards. Different track openings can be selected according to the actual construction needs on site to adapt to the width of the transport trolley wheels. Compared with the traditional fixed-size I-beam structure, it is simpler and more adaptable.

[0007] The underwater track's groove width is designed to be wider than that of the land-based track. This allows the trolley to move precisely along the track when operating on land. When the trolley enters the water, the wider groove effectively prevents wheel collisions with the track when faced with lateral loads caused by waves, thus reducing the risk of collision damage and extending the trolley's lifespan. Furthermore, the wider underwater groove design facilitates easier separation of the HDPE pipe from the track and allows it to float upwards after being submerged in water, preventing jamming or difficulty in detachment and improving operational convenience.

[0008] The overall track beam structure adopts a modular design, consisting of several unit sections connected in sequence. Each unit section can be prefabricated in the factory and quickly assembled on site, which improves the stability of construction quality and construction efficiency.

[0009] Preferably, the track is a channel steel with the groove facing upwards.

[0010] With this structural design, the preferred track is channel steel with the groove facing upwards. The raw materials for the track are easier to obtain, and the size of the channel steel opening can be selected according to the size of the trolley wheels, providing greater flexibility.

[0011] Preferably, a plurality of reinforcing plates are provided on both sides of the track, and the reinforcing plates connect the side wall of the track and the top of the foundation.

[0012] This structural design, with reinforcing plates connecting the sidewalls of the track to the foundation, forms an additional supporting structure. It effectively enhances the track's rigidity in both the lateral and vertical directions, enabling it to better resist vertical loads from beam loads and lateral loads from external forces such as wind and waves. This results in greater track stability during trolley movement and pipeline immersion in water, extending the track structure's service life.

[0013] Preferably, the reinforcing plates are arranged at intervals along the extension direction of the track, and the distance between adjacent reinforcing plates is 550mm-650mm.

[0014] This structural design, with the reinforcing plates evenly spaced along the track's extension direction, helps to uniformly transfer the vertical and lateral loads generated by the trolley and HDPE pipes to the foundation, thereby reducing the risk of track deformation or localized damage and improving the overall structural strength and durability.

[0015] Preferably, a fixing plate is pre-embedded in the top of the foundation, and the track is fixedly connected to the foundation through the fixing plate.

[0016] With this structural design, the fixing plate is pre-embedded in the top of the foundation. The fixing plate can be made of steel plate, which makes it easy to weld the track to the fixing plate. The pre-embedded fixing plate is arranged in advance during the foundation construction stage, which can ensure the accurate installation position of the track, thereby reducing the alignment error during later installation.

[0017] Preferably, one end of the base is configured as a first tongue and groove joint, and the other end of the base is configured as a second tongue and groove joint, with adjacent sections of the base connected by the tongue and groove joint.

[0018] This structural design, with tongue-and-groove joints between adjacent foundations, ensures a tight and continuous connection between them. This method is more stable than traditional simple splicing, effectively reducing loosening and displacement between unit sections, thereby improving the overall load-bearing capacity and deformation resistance of the track beam structure, and ensuring the safety and stability of HDPE pipes during transportation.

[0019] Preferably, adjacent foundation sections are connected by reinforcing steel bars.

[0020] This structural design provides a direct force path between adjacent foundations, allowing for rapid load transfer and dispersion, effectively preventing relative slippage and misalignment between foundations. This continuity enhances the overall structural rigidity of the track beam, ensuring smoother operation of the transport trolley.

[0021] Preferably, both the first tongue and the second tongue are provided with steel plates, and the steel plates of two adjacent foundation sections are welded with force-transmitting steel bars, and the two adjacent foundation sections are connected by the force-transmitting steel bars.

[0022] This structural design, employing reinforcement bars welded to the steel plates at the tongue and groove joints, achieves a high-strength connection between adjacent foundations. These reinforcement bars act as reinforcing components, transferring tensile and shear forces at the tongue and groove joints. This ensures that adjacent foundations not only rely on the physical interlocking of the tongue and groove but also achieve a reliable mechanical connection through the reinforcement bars, significantly improving the stability of the track beam structure under heavy loads. Furthermore, the reinforcement bars provide better impact resistance at the tongue and groove joints. Whether it's lateral loads from wind and waves or impact forces generated during trolley transport, the reinforcement bars effectively disperse impact loads, reduce stress concentration at the tongue and groove joints, and ensure the impact resistance and stability of the track beam structure.

[0023] Preferably, it also includes a connecting system, through which the foundations located side by side underwater are connected.

[0024] With this structural design, several unit sections are connected in sequence to form a track beam. Two track beams are set up side by side to support the transport trolley. Since the underwater environment is subject to lateral loads caused by wind and waves, a connecting system is added between the foundations set up side by side underwater. This enhances the lateral stiffness of the track beam structure and effectively prevents the foundations from lateral displacement or swaying caused by wind, waves or fluid impact underwater, ensuring the stability of the track system in the marine environment.

[0025] Preferably, the foundation located underwater has a pre-embedded C-shaped steel plate, and the foundations arranged side by side underwater are connected to the connecting system by bolts through the C-shaped steel plate.

[0026] With this structural design, the C-shaped steel plate provides excellent mechanical properties through its bending structure, allowing the forces between the underwater foundations to be evenly distributed, avoiding deformation or damage caused by excessive local stress, and ensuring the long-term stable operation of the track beam structure.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1. The track beam structure for transporting HDPE pipes provided by this utility model sets the track as an upward-facing groove structure. Different track openings can be selected according to the actual construction needs on site to adapt to the width of the transport trolley wheels. Compared with the traditional fixed-size I-beam structure, it is simpler and more adaptable.

[0029] 2. The track beam structure for transporting HDPE pipes provided by this utility model features an underwater track with a wider groove than the land-based track. This allows the trolley to move precisely along the track when on land. When the trolley enters the water, the wider underwater groove effectively prevents wheel collisions with the track, reducing the risk of collision damage and extending the trolley's service life, especially when facing lateral loads caused by waves. Furthermore, the wider underwater groove design facilitates easier separation of the HDPE pipe from the track and allows it to float upwards after being submerged, avoiding jamming or difficulty in detachment and improving operational convenience.

[0030] 3. The track beam structure for HDPE pipe transportation provided by this utility model adopts a modular design, which is composed of several unit sections connected in sequence. Each unit section can be prefabricated in the factory and quickly assembled on site, thereby improving the stability of construction quality and construction efficiency. Attached Figure Description

[0046] Example 1

[0047] When large HDPE pipes (diameter ≥ 3000 mm; weight ≥ 1 t) are transported from land to water, the HDPE pipes need to be placed on a transport trolley, which is then guided by a track beam to gradually move from land into the water. This embodiment provides a track beam structure for transporting HDPE pipes, such as... Figure 1 As shown, it includes several unit sections connected in sequence, which are connected in sequence to form a track beam. Two track beams are arranged side by side to support the transport trolley.

[0048] Specifically, the unit section includes a reinforced concrete foundation 1 and a track 2 fixedly connected to the top of the foundation 1. The track 2 is a channel-shaped structure with the opening facing upwards. Preferably, the track 2 is a channel steel with the opening facing upwards. The preferred choice of channel steel for the track 2 makes the raw materials for the track 2 easier to obtain, and the size of the channel steel opening can be selected according to the size of the trolley wheels, providing greater flexibility.

[0049] The slot in track 2 allows the wheels of the transport trolley to be inserted, specifically, as follows: Figure 2 As shown, the slot width of track 2 located on land is d, as follows: Figure 3 As shown, the width of the slot of the underwater track 2 is D, where d < D.

[0050] Furthermore, such as Figure 2 , Figure 3 As shown, several reinforcing plates 3 are installed on both sides of the track 2. These reinforcing plates 3 connect the sidewalls of the track 2 to the top of the foundation 1. Specifically, the reinforcing plates 3 can be triangular steel plates, with one side welded to the sidewall of the track 2 and the other side fixedly connected to the top surface of the foundation 1. This structural arrangement connects the sidewalls of the track 2 and the foundation 1, forming an additional support structure. It effectively enhances the rigidity of the track 2 in both the lateral and vertical directions, enabling the track 2 to better resist vertical loads caused by beam loads and lateral loads generated by external forces such as wind and waves. This results in greater stability of the track 2 during trolley movement and pipeline entry into water, extending the service life of the track 2 structure.

[0051] Furthermore, reinforcing plates 3 are arranged at intervals along the extension direction of track 2, with a spacing of 550mm-650mm between adjacent reinforcing plates 3, preferably 600mm. The uniformly spaced arrangement of reinforcing plates 3 along the extension direction of track 2 helps to evenly transfer the vertical and lateral loads generated by the trolley and HDPE pipes to the foundation 1, thereby reducing the risk of deformation or local damage to track 2 and improving the overall structural strength and durability.

[0052] Furthermore, such as Figure 2 , Figure 3 , Figure 4 As shown, a fixing plate 4 is pre-embedded in the top of the foundation 1, and the track 2 is fixedly connected to the foundation 1 through the fixing plate 4. With this structural setting, the fixing plate 4 is pre-embedded in the top of the foundation 1. The fixing plate 4 can be made of galvanized steel plate with a thickness of 2cm-3cm, which can facilitate welding the track 2 to the fixing plate 4. The pre-embedded fixing plate 4 is arranged in advance during the construction stage of the foundation 1, which can ensure the accurate installation position of the track 2, thereby reducing the alignment error during the later installation.

[0053] Furthermore, such as Figure 4As shown, one end of base 1 is configured as the first tongue-and-groove joint 11, and the other end of base 1 is configured as the second tongue-and-groove joint 12. Adjacent base 1 sections are connected by tongue-and-groove joints. Figure 4 For example, Figure 4 In the same base 1, the left side has the first tongue-and-groove joint 11, which is aligned with the top of base 1; the right side of the same base 1 has the second tongue-and-groove joint 12, which is aligned with the bottom of base 1. Figure 4 When the two bases 1 on the left and right are connected, the second tongue-and-groove joint 12 of the left base 1 is connected to the first tongue-and-groove joint 11 of the right base 1.

[0054] This structural design uses tongue-and-groove joints between adjacent foundations 1, ensuring a tight and continuous connection. This method is more stable than traditional simple splicing, effectively reducing loosening and displacement between unit sections, thereby improving the overall load-bearing capacity and deformation resistance of the track beam structure, and ensuring the safety and stability of HDPE pipes during transportation.

[0055] Furthermore, adjacent foundation sections 1 are connected by reinforcing steel bars 5. Preferably, as shown... Figure 4 As shown, steel plates 6 are installed on both sides of the first tongue-and-groove joint 11 and the second tongue-and-groove joint 12. Force-transferring steel bars 7 are welded to the steel plates 6 of adjacent foundation sections 1, and the adjacent foundation sections 1 are connected by these force-transferring steel bars 7. With this structural arrangement, a high-strength connection is achieved between adjacent foundation sections 1 by welding force-transferring steel bars 5 onto the steel plates 6 at the tongue-and-groove joints. The force-transferring steel bars 5, acting as reinforcements, transmit tensile and shear forces at the tongue-and-groove joints, ensuring that adjacent foundation sections 1 not only rely on the physical interlocking of the tongue-and-groove joints but also achieve a reliable mechanical connection through the steel bars, significantly improving the stability of the track beam structure under heavy loads. The force-transferring steel bars 5 also provide better impact resistance at the tongue-and-groove joints. Whether it is the lateral load of wind and waves or the impact force generated during the transport of the trolley, the force-transferring steel bars 5 can effectively disperse the impact load, reduce stress concentration at the tongue-and-groove joints, and ensure the impact resistance and stability of the track beam structure.

[0056] The track beam structure for HDPE pipe transportation provided in this embodiment sets the track 2 as an upward-facing groove structure. Different openings of the track 2 can be selected according to the actual construction needs on site to adapt to the width of the transport trolley wheels. Compared with the traditional fixed-size I-beam structure, it is simpler and more adaptable.

[0057] During use, the slot width of the underwater track 2 is designed to be wider than that of the land track 2. For example, the distance between the inner wall of the underwater track 2 slot and the wheels of the trolley is 3cm-5cm. When the trolley is running on land, it can be precisely guided along the track 2. When the trolley enters the water, facing the lateral load caused by wind and waves, which may cause the wheels to deviate or sway, the wider underwater slot can effectively prevent the wheels from colliding with the track 2, thereby reducing the risk of collision damage to the trolley during underwater operation and extending its service life. In addition, the wide underwater slot design also makes it easier to separate the HDPE pipe from the track 2 and float up after it is submerged in water, thus avoiding jamming or difficulty in detaching the trolley from the track 2 during the separation process and improving the convenience of operation.

[0058] The track beam structure for HDPE pipe transportation provided in this embodiment adopts a modular design, consisting of several unit sections connected sequentially. Each unit section can be prefabricated in the factory and quickly assembled on site, improving the stability of construction quality and construction efficiency.

[0059] Example 2

[0060] Based on Example 1, in order to further improve the underwater stability of the track beam structure in this embodiment, such as... Figure 5 As shown, the track beam structure for HDPE pipe transportation provided in this embodiment also includes a connecting system 8, and the foundations 1 located side by side underwater are connected by the connecting system 8.

[0061] Furthermore, such as Figure 6 , Figure 7 As shown, the foundation 1 located underwater has a pre-embedded C-shaped steel plate 9, and the connection system 8 can be a double I-beam connecting beam. It is foreseeable that the connection system 8 can also be an I-beam connecting beam. The foundation 1, which is set up side by side underwater, is bolted to the connection system 8 through the C-shaped steel plate 9.

[0062] In this structural configuration, several unit sections are sequentially connected to form a track beam. Two track beams are arranged side-by-side to support the transport trolley. Since underwater transport is subject to lateral loads caused by wind and waves, a connecting system 8 is added between the parallel underwater foundations 1. This enhances the lateral stiffness of the track beam structure and effectively prevents lateral displacement or swaying of the foundations 1 underwater due to wind, waves, or fluid impact, ensuring the stability of the track system in the marine environment. The C-shaped steel plate 9 provides excellent mechanical properties through its bending structure, allowing for a uniform distribution of forces between the underwater foundations 1. This avoids deformation or damage caused by excessive local stress, ensuring the long-term stable operation of the track beam structure.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
