This structure is welded as a whole, so it is difficult to manufacture, transport and install.
[0005] It can be seen that the cabin trusses in the prior art have obvious deficiencies and defects in use and structure, and need to be further improved urgently. How to create a truss that meets the requirements of lifting heavy objects with large-tonnage cranes, effectively reduces dead weight and reduces costs, and The nacelle truss with obvious wind load resistance is one of the current important research and development topics

Embodiment 1
[0040] Please refer to figure 1 As shown, the cabin truss of the one-piece longitudinal beam of the present invention includes a left side frame 1, a right side frame 2, a front beam 3, a middle beam 4, a rear beam 5 and an elastic support seat 6, and the left side frame 1 and the right side frame 2 are symmetrical set up.
[0041] Wherein, the left frame 1 includes pillars 11, triangle braces 12, diagonal braces 13 and longitudinal beams; correspondingly, the right frame 2 includes pillars 21, triangle braces 22, diagonal braces 23 and longitudinal beams. In this embodiment, the longitudinal beams One segment, one triangle brace 12 or one triangle brace 22, and one middle beam 4.
Embodiment 2
[0043] see figure 2 As shown, the cabin truss includes a left side frame 1, a right side frame 2, a front beam 3, a middle beam 4, a rear beam 5 and an elastic support seat 6, and the left side frame 1 and the right side frame 2 are left and right symmetrical.
[0044] Wherein, the left side frame 1 includes a pillar 11, a triangle brace 12, a diagonal brace 13, a longitudinal beam front section 14 and a longitudinal beam rear section 15; correspondingly, the right side frame 1 includes a pillar 21, a triangle brace 22, a diagonal brace 23, a longitudinal beam The front section 24 and the rear section 25 of the stringer. In this embodiment, the longitudinal beam is divided into the front section of the longitudinal beam and the rear section of the longitudinal beam, the number of triangle braces 12 and triangle braces 22 is two, and the number of middle beams 4 is two.
[0045] see Figure 4 As shown, the front beam of the present invention is provided with a frame connecti...

Abstract
The invention discloses an engine room truss of a wind generation set. The engine room truss comprises a left side frame, a right side frame, a front beam, a back beam and more than one middle beam, wherein the front end of the left side frame is connected with the front end of the right side frame through the front beam; the back end of the left side frame is connected with the back end of the right side frame through the back beam; and the middle beams are bridged between the left side frame and the right side frame. According to the engine room truss, a triangular support and an inclined strut are used for being connected with the bottom of a support; the improvement comes from a load transmitting path of a traveling car and an engine room cover; and the left side frame and the right side frame in bilateral symmetry are connected by the middle beams, so that the stability of the whole engine room truss is greatly improved and the wind loading resistance action is obvious.
Description
technical field [0001] The invention relates to the technical field of wind power, in particular to a nacelle truss of a wind turbine. Background technique [0002] Wind power is a clean energy, and the development of wind power energy has continuously promoted the development of wind turbines in the direction of large-scale and professionalization. With the increase of the capacity of a single wind turbine, the volume and weight of the transmission chain and other components placed in the nacelle also increase. The weight of the nacelle reflects the pros and cons of the design of the entire wind turbine. Compact to optimize supporting structures such as front and rear racks. [0003] In addition, the wind turbine nacelle generally needs to be equipped with a maintenance hoisting system to repair or replace components when they fail. High-power wind turbines, especially offshore high-power wind turbines, in order to reduce maintenance costs and improve maintainability, inst...
