Description

Technical Field

[0001] This invention relates to the field of engine manufacturing technology, and more particularly to engine storage fixtures. Background Technology

[0002] In the manufacturing, transportation, storage, and maintenance of large power equipment (such as engines, gas turbines, and large electric motors), specialized storage fixtures are critical infrastructure for ensuring the safety and stable performance of the equipment. Traditional storage methods often employ simple steel support frames or direct placement on the ground. Their structural design tends to focus on the static load-bearing function of the foundation, using several columns and main beams to form a basic load-bearing plane to meet the temporary placement needs of the equipment when it is not in operation.

[0003] With the continuous increase in single-unit power, the weight and size of the main equipment have increased significantly, placing higher demands on the structural strength, stability, and environmental adaptability of the storage fixtures. However, in practical applications, the traditional frame support structure of existing engine storage fixtures is poorly designed, often concentrating the weight of the main unit on a few load-bearing points. This causes the support beams and bottom components to be under localized overload for extended periods, and in severe cases, it can even lead to plastic deformation of the frame or damage to the support components, failing to provide long-term, stable, and reliable support and protection for the main unit. Summary of the Invention

[0004] The purpose of this invention is to provide an engine storage fixture to solve the aforementioned problems existing in the main equipment storage fixtures in related technologies.

[0005] To address the aforementioned problems in the existing technology, the present invention adopts the following technical solution:

[0007] Main beam frame;

[0008] The support assembly includes multiple support beams, all of which are disposed below the main beam frame;

[0009] Diagonal bracing is provided between adjacent support beams, and the diagonal bracing is inclined relative to the support beams;

[0010] The top support mechanism includes a cross brace and multiple top support components. The cross brace is disposed on the main beam frame, and the multiple top support components are arranged to form a polygonal structure. Each top support component includes a top support and two first stiffening plates. The two first stiffening plates are respectively disposed on two adjacent side walls of the main beam frame, and the two ends of the top support are respectively connected to the two first stiffening plates.

[0013] As an optional technical solution, the two reinforcing beams are arranged at an intersection point D, and the vertical axis passing through the intersection point D and perpendicular to the two reinforcing beams is L. The multiple top support components are connected end to end around the vertical axis L.

[0014] As an optional technical solution, the main beam frame further includes a second stiffening plate, which is connected to the first upright plate and is perpendicular to the first upright plate. The two ends of the second stiffening plate are respectively connected to the first main beam plate and the second main beam plate.

[0015] As an optional technical solution, the support beam includes a top plate, a bottom plate, a third stiffening plate, and a second vertical plate. The second vertical plate is connected between the top plate and the bottom plate, and the third stiffening plate is connected to the top plate. The third stiffening plate and the second vertical plate are arranged perpendicularly.

[0017] As an optional technical solution, the support beam further includes a fourth stiffening plate, which is connected to the base plate and is perpendicular to the second upright plate. The two ends of the diagonal brace are respectively connected to the third stiffening plate and the fourth stiffening plate corresponding to two adjacent support beams.

[0019] As an optional technical solution, there are multiple supporting mechanisms, and the multiple supporting mechanisms are distributed in a matrix on the main beam frame.

[0020] The engine storage fixture provided by this invention has at least the following beneficial effects:

[0021] The engine storage fixture includes a main beam frame, support components, diagonal braces, and a top support mechanism. The support components consist of multiple support beams positioned below the main beam frame.

[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] For example, such as Figures 1-2As shown, the main engine 100 is a large marine engine, and the main engine 100 is mounted on the bracket 200.

[0041] like Figures 3 to 7 As shown, this embodiment provides an engine storage fixture, which includes a main beam frame 1, a support assembly, diagonal braces 3, and a top support mechanism. The support assembly includes multiple support beams 2, all positioned below the main beam frame 1. Diagonal braces 3 are positioned between adjacent support beams 2 and are inclined relative to the support beams 2. The top support mechanism includes a cross brace 4 and multiple top support components 5. The cross brace 4 is positioned on the main beam frame 1, and the multiple top support components 5 form a polygonal structure. Each top support component 5 includes a top support 51 and two first stiffening plates 52. The two first stiffening plates 52 are respectively positioned on two adjacent side walls of the main beam frame 1, and the two ends of the top support 51 are respectively connected to the two first stiffening plates 52.

[0042] It should be noted that the main beam frame 1, support components, diagonal braces 3, and top support mechanism of the engine storage fixture are all made of Q235A structural steel or higher strength steel, resulting in high structural strength and long service life. Furthermore, all of the above structures are rigidly connected by welding, ensuring direct force transmission, reliable connections, and no loosening or gaps.

[0043] The main beam frame 1 and the support assembly form the upper and lower parts of the engine storage fixture. Multiple support beams 2 are evenly distributed at the bottom of the main beam frame 1. The main beam frame 1 is fixedly installed above the support assembly. The main beam frame 1 is used to store the main engine 100 with a bracket 200, and the support assembly is used to support the main beam frame 1. The two ends of the diagonal brace 3 are welded between two adjacent support beams 2, and the diagonal brace 3 is set at a relative inclination to resist the lateral force and overturning moment of the main engine 100 on the support beams 2.

[0044] The cross brace 4 is fixedly connected to the main beam frame 1 by welding to suppress buckling of the main beam frame 1, thereby improving the overall rigidity and fatigue resistance of the main beam frame 1. Multiple top support components 5 are connected end to end and form a closed polygonal structure to disperse stress concentration. Two first stiffening plates 52 are respectively welded and fixed to two adjacent side walls of the main beam frame 1. The top support 51 is fixedly installed between the two first stiffening plates 52 by welding to evenly distribute the load of the host 100 on the main beam frame 1 and the support components and prevent local overload.

[0045] The operation of this engine storage fixture is as follows: Based on the different models of the main engine 100 to be stored, a suitable storage device is selected. The main engine 100 to be stored in the workshop is transported to the main engine 100 storage yard by a flatbed truck. A crane in the yard lifts the main engine 100 to be stored onto the main beam frame 1 of the outdoor engine storage fixture. The support components and top support mechanism bear the pressure of the main engine 100. The lifting wire rope is then removed, and the crane leaves. This engine storage fixture can store the main engine 100, preventing water, snow, and dust from contaminating it, thus protecting the main engine 100. Furthermore, it meets the requirements of convenient use and improves the efficiency of operators.

[0046] Furthermore, referring to Figures 3-4 The main beam frame 1 includes multiple main beams 11 connected end to end in sequence. The main beam 11 includes a first main beam plate 111 and a second main beam plate 112, and a first vertical plate 113 connected between the first main beam plate 111 and the second main beam plate 112. The side wall of the first vertical plate 113 is connected to the first stiffening plate 52, and the bottom of the first main beam plate 111 is connected to the first stiffening plate 52.

[0047] The first vertical plate 113 has an I-shaped longitudinal section. It is welded between the first main beam plate 111 and the second main beam plate 112 to form a main beam 11. Multiple main beams 11 are connected end to end to form a closed load-bearing main beam frame 1, which is used to improve bending and torsional stiffness. The first stiffening plate 52 is fixed to the side wall of the first vertical plate 113 by welding and fixedly connected to the bottom of the first column beam plate. The top support 51 fixedly connected between two first stiffening plates 52 is used to evenly distribute the load of the main unit 100 on the main beam frame 1 and the support components, and prevent local overload.

[0048] Furthermore, referring to Figure 5 The cross brace 4 includes two reinforcing beams 41, which are arranged vertically and cross each other. The reinforcing beams 41 are connected to the side wall of the first main beam plate 111. Both ends of the reinforcing beams 41 are welded to the side wall of the first main beam plate 111 to suppress buckling of the main beam frame 1, thereby improving the overall rigidity and fatigue resistance of the main beam frame 1.

[0049] Furthermore, continue to refer to Figure 5 Two reinforcing beams 41 are arranged at an intersection point D. The vertical axis passing through the intersection point D and perpendicular to the two reinforcing beams 41 is L. Multiple top support components 5 are connected end to end around the vertical axis L.

[0050] The intersection point of the two reinforcing beams 41 is D. The vertical axis L passes through the intersection point D and is perpendicular to the two reinforcing beams 41. With the vertical axis L as the center line, multiple top support components 5 are connected end to end around the vertical axis L to form a closed polygonal structure, which is used to disperse stress concentration. The multiple top support components 5, together with the cross brace 4, can provide good support for the main unit 100, and suppress the buckling of the main beam frame 1, thereby improving the overall rigidity and fatigue resistance of the main beam frame 1.

[0051] Furthermore, continue to refer to Figures 3-4 The main beam frame 1 also includes a second stiffening plate 12, which is connected to the first vertical plate 113 and is perpendicular to the first vertical plate 113. The two ends of the second stiffening plate 12 are respectively connected to the first main beam plate 111 and the second main beam plate 112.

[0052] The second stiffening plate 12 is fixedly welded to the side of the first upright plate 113, and its two ends are respectively fixedly welded to the bottom of the first main beam plate 111 and the top of the second main beam plate 112. The second stiffening plate 12 is perpendicular to the first upright plate 113, the first main beam plate 111, and the second main beam plate 112. The second stiffening plate 12 can further improve the structural strength of the main beam frame 1, suppress buckling of the main beam frame 1, and improve the overall stiffness and fatigue resistance.

[0053] Furthermore, continue to refer to Figures 3-4 The supporting beam 2 includes a top plate 21, a bottom plate 22, a third stiffening plate 23, and a second vertical plate 24. The second vertical plate 24 is connected between the top plate 21 and the bottom plate 22, and the third stiffening plate 23 is connected to the top plate 21. The third stiffening plate 23 and the second vertical plate 24 are arranged perpendicularly.

[0054] The two ends of the second vertical plate 24 are fixedly connected to the top plate 21 and the bottom plate 22 by welding, respectively. The top plate 21 converts the concentrated load of the main engine 100 into a uniformly distributed load, and the bottom plate 22 can reduce the pressure on the hull deck. The third stiffening plate 23 is fixedly connected to the top plate 21 and the second vertical plate 24 by welding, and the third stiffening plate 23 is perpendicular to both the top plate 21 and the second vertical plate 24. There are multiple third stiffening plates 23, which are spaced apart along the outer periphery of the second vertical plate 24 to suppress buckling of the main beam frame 1, disperse stress concentration, and improve overall rigidity and fatigue resistance.

[0055] Furthermore, referring to Figure 4 The support beam 2 also includes a fourth stiffening plate 25, which is connected to the bottom plate 22 and is perpendicular to the second vertical plate 24. The two ends of the diagonal brace 3 are respectively connected to the third stiffening plate 23 and the fourth stiffening plate 25 of the two adjacent support beams 2.

[0056] The fourth stiffening plate 25 is fixedly connected to the base plate 22 by welding, and the fourth stiffening plate 25 is perpendicular to both the second upright plate 24 and the base plate 22. There are two diagonal braces 3, which are arranged in a crisscross pattern. The two ends of one diagonal brace 3 are respectively fixed to the upper third stiffening plate 23 and the lower fourth stiffening plate 25 on two adjacent support beams 2, and the diagonal brace 3 is located on the same side of the third stiffening plate 23 and the fourth stiffening plate 25. The two ends of the other diagonal brace 3 are respectively fixed to the upper third stiffening plate 23 and the lower fourth stiffening plate 25 on two adjacent support beams 2, and the diagonal brace 3 is located on the other side of the third stiffening plate 23 and the fourth stiffening plate 25, which are used to resist the lateral force and overturning moment of the main unit 100 on the support beams 2.

[0057] Furthermore, continue to refer to Figure 5 There are multiple supporting mechanisms, which are distributed in a matrix on the main beam frame 1, making the whole structure centrally symmetrical, so that the load center coincides with the structural center of gravity, reducing the additional bending moment. When the main unit 100 is too large, the number of storage devices can be increased and combined, and then multiple main units 100 can be stored in the combined storage devices in sequence.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
