[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown in the figure, a modular engine room overhead crane beam provided by this utility model includes a left support frame and a right support frame. A transformer room partition beam 1, a water-cooled bracket front beam 3 and a lifting beam 7 are arranged sequentially from back to front between the left support frame and the right support frame. The transformer room partition beam 1, the water-cooled bracket front beam 3, and the lifting beam 7 are all provided with a second connection structure on both sides. The transformer room partition beam 1, the water-cooled bracket front beam 3, and the lifting beam 7 are fixedly connected to the left support frame and the right support frame respectively through the second connection structure. The left and right support frames are provided with a first connecting structure, and the left and right support frames are fixedly connected by the first connecting structure.

[0022] The left support frame includes a left front triangular frame 6, a left middle triangular frame 4 is fixedly connected to the rear side of the left front triangular frame 6 through a first connecting structure, and a left rear triangular frame 2 is fixedly connected to the rear side of the left middle triangular frame 4 through a first connecting structure.

[0023] The above scheme demonstrates that the triangular frame structure has high stability and load-bearing capacity, effectively disperses stress, reduces local stress concentration, and achieves modular connection through the first connecting structure, ensuring the rigidity of the overall structure, facilitating disassembly and maintenance, and improving the structure's resistance to deformation.

[0024] The right-side support frame includes a right front triangular frame 8, a right middle triangular frame 10 fixedly connected to the rear of the right front triangular frame 8 via a first connecting structure, a right rear triangular frame 11 fixedly connected to the rear of the right middle triangular frame 10 via a first connecting structure, the two sides of the lifting beam 7 fixedly connected to the left front triangular frame 6 and the right front triangular frame 8 respectively via a second connecting structure, the two sides of the water-cooled bracket front beam 3 fixedly connected to the left middle triangular frame 4 and the right middle triangular frame 10 respectively via a second connecting structure, and the two sides of the transformer room partition beam 1 fixedly connected to the left rear triangular frame 2 and the right rear triangular frame 11 respectively via a second connecting structure.

[0025] The above solution can make the overall structure more stable and robust, with tight connections between parts, effectively dispersing and bearing forces from different directions, and improving the structure's load-bearing capacity and resistance to deformation.

[0026] The first connecting structure includes a first bolt 12, and there are several first bolts 12 evenly distributed. A first washer 13 is fitted on the surface of the first bolt 12. The first washer 13 is used in conjunction with the left front triangular frame 6, the left middle triangular frame 4, the right front triangular frame 8, and the right middle triangular frame 10. A first nut 14 is threaded onto the surface of the first bolt 12. A second washer 15 is provided between the first washer 13 and the first nut 14. The surface of the second washer 15 is used in conjunction with the left middle triangular frame 4, the left rear triangular frame 2, the right middle triangular frame 10, and the right rear triangular frame 11.

[0027] The above scheme enhances the stability and reliability of the structural connection. The first washer 13 works in conjunction with the left front triangular frame 6, the left middle triangular frame 4, the right front triangular frame 8, and the right middle triangular frame 10 to effectively distribute the pressure and prevent local stress concentration. The first nut 14 is threadedly connected to the first bolt 12 to ensure the tightness of the connection. The second washer 15, in conjunction with the left middle triangular frame 4, the left rear triangular frame 2, the right middle triangular frame 10, and the right rear triangular frame 11, ensures uniform stress distribution in the structure and improves the overall load-bearing capacity of the structure.

[0028] The second connection structure includes a number of second bolts 16, which are evenly distributed. A third washer 17 is fitted on the surface of the second bolt 16. The surface of the second bolt 16 is used in conjunction with the transformer room partition beam 1, the front beam of the water-cooled bracket 3, the lifting beam 7, the left front triangular frame 6, the left middle triangular frame 4, the left rear triangular frame 2, the right front triangular frame 8, the right middle triangular frame 10, and the right rear triangular frame 11. A second nut 18 is threaded onto the surface of the second bolt 16. A fourth washer 19 is provided between the third washer 17 and the second nut 18. The fourth washer 19 is used in conjunction with the left front triangular frame 6, the left middle triangular frame 4, the left rear triangular frame 2, the right front triangular frame 8, the right middle triangular frame 10, and the right rear triangular frame 11.

[0029] The above scheme ensures a stable connection between the transformer room partition beam 1, the front beam 3 of the water-cooled bracket, the lifting beam 7, the right front triangular frame 8, the left middle triangular frame 4, the left rear triangular frame 2, the right middle triangular frame 10, and the right rear triangular frame 11, enhancing the overall structural stability and load-bearing capacity. The third washer 17 fitted on the surface of the second bolt 16 and the fourth washer 19 set between the second nut 18 and the third washer 17 effectively reduce wear and loosening at the connection points, improving the service life of the structure.

[0030] The bottom of the left front triangular frame 6 is fixedly connected to the left upright frame 5, the bottom of the right front triangular frame 8 is fixedly connected to the right upright frame 9, and the bottoms of the left middle triangular frame 4 and the right middle triangular frame 10 are at an angle of five degrees.

[0031] The above scheme provides a stable supporting foundation, enhances the structural stability, and the bottom of the left and right triangular frames 4 and 10 are at a 5-degree angle, which helps to distribute the force borne by the structure, reduce stress concentration, improve the load-bearing capacity and deformation resistance of the structure, adapt to different terrains or usage environments, and increase the flexibility of the structure.

[0032] The working principle of this utility model: In use, the overall support structure is formed by the left and right support frames. The left support frame consists of a left front triangular frame 6, a left middle triangular frame 4, and a left rear triangular frame 2, which are sequentially fixedly connected by a first connecting structure. The right support frame consists of a right front triangular frame 8, a right middle triangular frame 10, and a right rear triangular frame 11, which are sequentially fixedly connected by a first connecting structure. The design of the triangular frame structure ensures high overall stability and load-bearing capacity. The modular connection effectively distributes the force and reduces local stress concentration. The transformer room partition beam 1, the water-cooled bracket front beam 3, and the lifting beam 7 are sequentially arranged between the left and right support frames from back to front and are fixedly connected to the corresponding triangular frames by a second connecting structure. The lifting beam 7 connects the left front triangular frame 6 and the right front triangular frame 8, the water-cooled bracket front beam 3 connects the left middle triangular frame 4 and the right middle triangular frame 10, and the transformer room partition beam 1 connects the left rear triangular frame 2 and the right rear triangular frame 11. The frame 11 ensures even stress distribution across all parts, enhancing the overall structural rigidity. The first connection structure, through evenly distributed first bolts 12, first washers 13, second washers 15, and first nuts 14, achieves a stable connection between the left and right support frames and the left front triangular frame 6, left middle triangular frame 4, right front triangular frame 8, and right middle triangular frame 10, effectively dispersing pressure and preventing localized deformation. The second connection structure, through evenly distributed second bolts 16, third washers 17, fourth washers 19, and second nuts 18, ensures a reliable connection between the crossbeam and the triangular frame, reducing wear and loosening. The left front triangular frame 6 has the left upright 5 fixed to its bottom, and the right front triangular frame 8 has the right upright 9 fixed to its bottom, providing stable support for the whole structure. The left middle triangular frame 4 and right middle triangular frame 10 have a five-degree angled bottom design, which helps to disperse structural stress, reduce stress concentration, improve load-bearing capacity and deformation resistance, and enhance adaptability to different terrains or usage environments.

[0033] In summary, this modular nacelle overhead crane beam, through the installation of transformer room partition beam 1, left rear triangular frame 2, water-cooled bracket front beam 3, left middle triangular frame 4, left upright 5, left front triangular frame 6, lifting beam 7, right front triangular frame 8, right upright 9, right middle triangular frame 10, right rear triangular frame 11, first bolt 12, first washer 13, first nut 14, second washer 15, second bolt 16, third washer 17, second nut 18, and fourth washer 19, solves the problem that existing nacelle overhead crane beams, due to their large load-bearing capacity, are mostly directly supported by columns, and the nacelle overhead crane beams on both sides are fixed to the side walls, resulting in poor stability and easy tilting on one side, leading to stress damage to the nacelle overhead crane beams.
