[0002] With the rapid development of renewable energy, wind power generation has attracted much attention as one of the clean energy sources. In wind turbines, the transmission box is a vital component, and its adjustment support device is the key to ensure the normal operation of the transmission box. By supporting and adjusting the position and posture of the transmission box, it ensures that the transmission system maintains stable and efficient operation during the operation of the wind turbine. In the future development of the wind power industry, it will play an increasingly important role and make greater contributions to the advancement and improvement of wind power technology.

[0003] The existing wind turbine transmission box adjustment support device can only meet the support requirements for the wind turbine transmission box. In the face of different construction scenarios, when the position of the wind turbine transmission box needs to be adjusted, this type of wind turbine transmission box adjustment support device cannot meet the work requirements, which will affect the installation and adjustment efficiency of the wind turbine transmission box and cause certain losses. Some wind turbine transmission box adjustment support devices have a fixed structure, which can only meet the adjustment and support requirements for one type of wind turbine transmission box. However, when faced with wind turbine transmission boxes of different sizes, this type of wind turbine transmission box adjustment support device cannot adjust and support them, which affects work efficiency and requires extra time to find a matching wind turbine transmission box adjustment support device, which is time-consuming and labor-intensive.

[0004] Therefore, it is urgent to provide a wind turbine transmission box lifting mechanism to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is that the existing wind turbine transmission box adjustment support device can only meet the support requirements for the wind turbine transmission box. In the face of different construction scenarios, when the position of the wind turbine transmission box needs to be adjusted, this type of wind turbine transmission box adjustment support device cannot meet the work requirements, which will affect the installation and adjustment efficiency of the wind turbine transmission box and cause certain losses. Some wind turbine transmission box adjustment support devices have a fixed structure, which can only meet the adjustment and support requirements for one type of wind turbine transmission box. However, when faced with wind turbine transmission boxes of different sizes, this type of wind turbine transmission box adjustment support device cannot adjust and support them, which affects work efficiency and requires extra time to find a matching wind turbine transmission box adjustment support device, which is time-consuming and labor-intensive.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a wind turbine transmission box lifting mechanism, including a bottom plate, a plurality of limit sliding grooves are opened on the top of the bottom plate, two first sliding bars are fixedly connected to the top of the bottom plate, a driving motor is installed at the middle position of the top of the two first sliding bars, the output ends of the two driving motors are fixedly connected to a rotating block, the tops of the two rotating blocks are fixedly connected to a connecting block, the tops of the two first sliding bars are slidably connected to two sliding blocks, a first hydraulic cylinder is installed inside the plurality of sliding blocks, a fixed block is fixedly connected to one side of the plurality of sliding blocks, and a connecting bar is rotatably connected inside the plurality of fixed blocks;

[0007] The tops of the plurality of sliding blocks are each provided with an adjusting support structure, and the tops of the plurality of adjusting support structures are each installed with a supporting plate.

[0008] The utility model is further configured as follows: the connecting strip is installed between the connecting block and the fixing block.

[0009] Through the above technical solution, when the connecting block is rotated, the fixed block and the slider fixedly connected thereto will also move along with the movement of the connecting strip, thereby realizing the movement of the slider.

[0010] The utility model is further configured as follows: the output end of the first hydraulic cylinder is in contact with the inner wall of the corresponding sliding block.

[0011] Through the above technical solution, when the driving motor moves to control the sliding of the slider, the first hydraulic cylinder will not operate, affecting the working process of the driving motor. When the driving motor completes the control and adjustment of the slider, the first hydraulic cylinder will start to operate, and its output end will be against the inner wall of the slider, so that the slider cannot continue to move, thereby ensuring the smooth progress of subsequent adjustment work.

[0012] The utility model is further configured as follows: the adjustment support structure includes a fixed plate fixedly connected to the top of the sliding block, two second sliding bars are fixedly connected to the top of the fixed plate, a plurality of screw holes are provided on the tops of the two second sliding bars, two adjustment bars are installed between the two second sliding bars, a plurality of screws are installed on the tops of the two adjustment bars, the tops of the two adjustment bars are rotatably connected to two support bars, two second hydraulic cylinders are installed on the top of the fixed plate, and a plurality of support columns are fixedly connected to the bottom of the fixed plate.

[0013] Through the above technical solution, after completing the adjustment work of the slider, the second hydraulic cylinder can be started and controlled, and the adjustment bar can be driven to slide through the output end of the second hydraulic cylinder. While the adjustment bar is sliding, the support bar on the adjustment bar will also start to move, thereby realizing the top lifting function. After completing the adjustment work, the screws are fixed on the second slide bar to ensure that the second slide bar can no longer move, thereby ensuring the stability of subsequent installation work.

[0014] The utility model is further configured as follows: the inner wall of the adjustment bar is attached to and slides on the outer wall of the second sliding bar.

[0015] Through the above technical solution, the fitting and sliding design can increase the stability of the system, ensure the uniform and reliable transmission of force, and ensure that the adjustment bar will not easily deviate when sliding on the second slide bar, thereby affecting subsequent installation work.

[0016] The utility model is further configured as follows: the output end of the second hydraulic cylinder is attached to the inner side of the adjustment bar.

[0017] Through the above technical solution, the second hydraulic cylinder is used to drive the adjustment bar to move. After the adjustment work is completed, the second hydraulic cylinder will stop working, so that the adjustment bar is fixed in the specified position, which is convenient for the staff to install subsequent parts.

[0018] The utility model is further configured as follows: the outer wall of the support column is fitted to the inner wall of the limiting sliding groove.

[0019] Through the above technical solution, the outer wall fits against the inner wall of the limiting slide groove to provide more stable support, ensuring that the support column is accurately and stably positioned in the limiting slide groove. It can also effectively prevent the support column from accidentally shifting or shaking during use, thereby improving the safety and stability of the system.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1. The utility model is designed to adjust the support structure. When the height of the support plate is adjusted according to the actual situation, it is only necessary to use the second hydraulic cylinder inside the adjustment support structure to continuously adjust the position of the adjustment bar by controlling the position of the output end of the second hydraulic cylinder, so that the position between the support bars is continuously changed until the support plate on the support bar reaches the specified height. Then, the wind turbine transmission box can be installed on the support plate. By adjusting the support structure, it can easily help the staff cope with various construction scenes, so that the versatility of the device is greatly increased;

[0022] 2. The utility model designs the first slide bar and the slider, and continuously adjusts the position of the slider on the slide bar so that the adjustment support structure on the slider will also move accordingly until the support plate is installed with the wind turbine transmission box. By adjusting the position of the slider, the device can make corresponding adjustments according to wind turbine transmission boxes of different sizes, ensuring that the support plate can accommodate the wind turbine transmission box to the greatest extent.
