Description

Technical Field

[0001] This invention belongs to the field of cracking furnace structure technology, and more specifically, relates to a transport and reinforcement support structure for an overall module of an ethylene cracking furnace. Background Technology

[0002] The ethylene cracking furnace is the core equipment of an ethylene cracking unit, characterized by its large size, heavy weight, complex structure, multi-disciplinary integration, and long installation period. During the manufacturing or installation of the ethylene cracking furnace, construction work is highly concentrated, and the workload of personnel is high. If construction is organized in a conventional manner, it is difficult to achieve the project's schedule, safety, and quality objectives. To solve these problems, on-site prefabrication and assembly into integral modules can be adopted, which are then transported to the site for overall installation.

[0003] The support system is crucial to the implementation of the entire furnace module. During the processing and transportation of the overall module, the support system plays a role in supporting the module, preventing overturning, and distributing the load. However, due to the characteristics of the pyrolysis furnace module, such as large weight, high center of gravity, and poor stability, its fixing and transportation are quite difficult, which places high demands on the transport support system. Most existing pyrolysis furnace support systems have complex structures. When the pyrolysis furnace needs to be transported, the support system must be disassembled and then the corresponding transport support structure must be assembled. This not only makes the construction process complicated, but also makes the disassembly of the support system time-consuming and labor-intensive, affecting the overall construction efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a simple, stable, and easy-to-transport and disassemble integrated modular transport and reinforcement support structure for an ethylene cracking furnace.

[0005] To achieve the above objectives, the present invention provides an integral modular transportation and reinforcement support structure for an ethylene cracking furnace, comprising furnace body steel columns, a transverse truss structure, a longitudinal truss structure, and a horizontal truss structure. The furnace body steel columns are located outside the cracking furnace body. The transverse truss structure, the longitudinal truss structure, and the horizontal truss structure are detachably connected to each other. The transverse truss structure and the horizontal truss structure are both connected to the furnace body steel columns.

[0006] The longitudinal truss structure includes multiple support steel columns and multiple longitudinal steel beams. The multiple support steel columns are evenly distributed on both sides of the cracking furnace in the vertical direction, and adjacent support steel columns are connected by the longitudinal steel beams.

[0007] The horizontal truss structure includes multiple transport beams and multiple horizontal steel beams. The multiple transport beams are arranged in parallel. Both ends of the transport beams are detachably connected to the support steel column and the furnace body steel column, respectively. Adjacent transport beams are connected by the horizontal steel beams.

[0008] The transverse truss structure includes multiple transverse steel beams and multiple diagonal support beams. The two ends of the transverse steel beams are detachably connected to the top of the support steel column and the furnace body steel column, respectively. The diagonal support beams are inclined and are detachably connected to the support steel column and the furnace body steel column, respectively.

[0009] Furthermore, the inclined support beam includes an upper inclined support beam and a lower inclined support beam, the upper inclined support beam being located above the transverse steel beam, and the lower inclined support beam being located between the transverse steel beam and the transport beam.

[0010] Furthermore, it also includes an auxiliary support beam, one end of which is connected to the upper or lower support beam, and the other end is connected to the transverse steel beam.

[0011] Furthermore, the upper and lower support beams are arranged in parallel, and the angle between the upper support beam and the transverse steel beam is 45°. The auxiliary support beam is perpendicular to the upper and lower support beams and is connected to the middle of the upper and lower support beams.

[0012] Furthermore, the furnace body steel columns are evenly distributed outside the pyrolysis furnace, and the furnace body steel columns are vertically arranged, with temporary foundations provided at the bottom of the furnace body steel columns.

[0013] Furthermore, a pair of longitudinal steel beams are provided between two adjacent support steel columns, the pair of longitudinal steel beams are distributed vertically and the longitudinal steel beams are perpendicular to the support steel columns, the transport beam is set horizontally and the transport beam is perpendicular to the support steel columns.

[0014] Furthermore, both ends of the horizontal steel beam are connected to the middle of the transport beam, and the horizontal steel beam is perpendicular to the transport beam.

[0015] Furthermore, both ends of the transport beam are bolted to the support steel column and the furnace body steel column, respectively; both ends of the transverse steel beam are bolted to the support steel column and the furnace body steel column, respectively; and both ends of the inclined support beam are bolted to the support steel column and the furnace body steel column, respectively.

[0016] Furthermore, the longitudinal truss structure also includes longitudinal diagonal supports, which are inclinedly arranged between two adjacent support steel columns, and both ends of the longitudinal diagonal supports are connected to the support steel columns.

[0017] Furthermore, the horizontal truss structure also includes horizontal diagonal supports, which are "X" shaped and connected to the transport beam at all four corners.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention, through the combination of detachable horizontal truss structure, horizontal truss structure and longitudinal truss structure, can resist lateral loads and share vertical loads during the overall modular processing and assembly of the pyrolysis furnace, ensuring the safety of the overall modular assembly of the pyrolysis furnace, playing a beneficial reinforcement role, and achieving the stability of the pyrolysis furnace as a whole.

[0019] Meanwhile, a horizontal truss structure has been added, which can support the transport of the module, prevent the module from tipping over, and achieve safe transport. Compared with the existing support structure, during the transport of the entire pyrolysis furnace module, the present invention does not require disassembly of the support system and can be transported directly together with the support system. After the transport is completed, the support system only needs to be disassembled once. There is no need to install the transport support structure before transport, which is conducive to promoting the progress of the project and improving the quality of the project.

[0020] Meanwhile, the transverse truss structure, horizontal truss structure and longitudinal truss structure of the present invention are all connected in a detachable manner. After assembly and transportation, only the corresponding truss modules need to be removed, which not only shortens the disassembly period of the support system, but also facilitates the next installation and use.

[0026] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] This embodiment provides a transport and reinforcement support structure for an integral module of an ethylene cracking furnace, including furnace body steel columns 6, a transverse truss structure, a longitudinal truss structure, and a horizontal truss structure. The furnace body steel columns 6 are located outside the cracking furnace body and can also serve as transport support columns. The furnace body steel columns 6 are evenly distributed outside the radiant furnace chamber of the cracking furnace, and the furnace body steel columns 6 are vertically arranged. A temporary foundation 12 is provided at the bottom of the furnace body steel columns 6, which can support the furnace body steel columns 6 and create a height difference between the furnace body steel columns 6 and the ground, facilitating transportation.

[0028] The transverse truss structure, longitudinal truss structure, and horizontal truss structure are detachably connected to each other by bolts, and both the transverse truss structure and the horizontal truss structure are connected to the furnace body steel column 6.

[0029] The longitudinal truss structure includes multiple support steel columns 4 and multiple longitudinal steel beams 7. The multiple support steel columns 4 are evenly distributed on both sides of the cracking furnace in the vertical direction, and two adjacent support steel columns 4 are connected by the longitudinal steel beams 7.

[0030] Furthermore, a pair of longitudinal steel beams 7 are provided between two adjacent support steel columns 4. The pair of longitudinal steel beams 7 are distributed vertically and are perpendicular to the support steel columns 4. The transport beam 5 is set horizontally and is perpendicular to the support steel columns 4. The vertically distributed longitudinal steel beams 7 can be adapted to the transverse truss structure and the horizontal truss structure respectively, increasing the connection stability of the longitudinal truss structure with other truss structures, and increasing the structural strength of the longitudinal truss structure.

[0031] Furthermore, the longitudinal truss structure also includes a longitudinal diagonal support 8, which is inclinedly arranged between two adjacent support steel columns 4, and both ends of the longitudinal diagonal support 8 are bolted to the support steel column 4. By adding the longitudinal diagonal support 8, a triangular structure can be formed between adjacent support steel columns 4, thereby increasing the stability and structural strength of the longitudinal truss structure.

[0032] The horizontal truss structure includes multiple transport beams 5 and multiple horizontal steel beams 10. The multiple transport beams 5 are arranged in parallel. The two ends of each transport beam 5 are respectively bolted to the support steel column 4 and the furnace body steel column 6. Adjacent transport beams 5 are connected by the horizontal steel beams 10. The two ends of each horizontal steel beam 10 are connected to the middle of the transport beam 5, and the horizontal steel beams 10 are perpendicular to the transport beams 5. The horizontal steel beams 10 can connect the transport beams 5, so that the horizontal truss structure forms an integral structure, increasing the stability and structural strength of the horizontal truss structure.

[0033] Furthermore, the horizontal truss structure also includes horizontal diagonal supports 11, which are "X" shaped and connected to the transport beam 5 at all four corners. The horizontal diagonal supports can form a mesh structure in the horizontal truss structure, reducing the gaps between the connections of the horizontal truss structure, increasing stability and structural strength, and facilitating the movement and construction of the horizontal truss structure by operators.

[0034] The transverse truss structure includes multiple transverse steel beams 1 and multiple diagonal support beams. The two ends of the transverse steel beams 1 are respectively connected to the support steel column 4 and the furnace body steel column 6 by bolts.

[0035] The inclined support beam includes an upper inclined support beam 2 and a lower inclined support beam 3. The upper inclined support beam 2 is located above the transverse steel beam 1, and the lower inclined support beam 3 is located between the transverse steel beam 1 and the transport beam 5. Both ends of the inclined support beam are bolted to the support steel column 4 and the furnace body steel column 6, respectively. The upper inclined support beam 2 and the lower inclined support beam 3 are arranged parallel to each other, and the angle between the upper inclined support beam 2 and the transverse steel beam 1 is 45°. The inclined support beam increases the stability of the connection between the longitudinal truss structure and the furnace body steel column 6, and increases the overall structural strength of the support system. The inclined support beam also serves as an auxiliary connection. The auxiliary support beam 9 has one end connected to the upper support inclined beam 2 or the lower support inclined beam 3, and the other end connected to the transverse steel beam 1. The auxiliary support beam 9 is perpendicular to the upper support inclined beam 2 and the lower support inclined beam 3, and is connected to the middle of the upper support inclined beam 2 and the lower support inclined beam 3. The auxiliary support beam 9 can support the inclined support beam, increase the structural strength of the inclined support beam, and the two ends of the transverse steel beam 1 are detachably connected to the top of the support steel column 4 and the furnace body steel column 6, respectively. The inclined support beam is inclined, and the two ends of the inclined support beam are detachably connected to the support steel column 4 and the furnace body steel column 6, respectively.

[0036] During assembly, the furnace body steel column 6 is first bolted to the temporary foundation 12. Then, the transverse truss structure, longitudinal truss structure and horizontal truss are assembled and connected to complete the support system construction. During transportation, the transport beam 5 is simply fixed to the vehicle for transportation. After transportation, the support system can be disassembled.

[0037] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
