Description

Technical Field

[0001] This utility model relates to the field of wind turbine main shaft support technology, specifically a support device for connecting wind turbine main shafts. Background Technology

[0002] The wind turbine main shaft is one of the core components of a wind turbine generator set, converting the mechanical energy of the rotating wind turbine into electrical energy. During the docking process of the wind turbine main shaft, the support device plays a crucial role, ensuring that the main shaft remains stably and accurately aligned during the docking process. This is of great significance for ensuring the normal operation of the wind turbine generator set, improving power generation efficiency, and extending equipment life. To accommodate wind turbine main shafts of different sizes, the support device is equipped with an adjustment mechanism. However, this adjustment mechanism has a simple structure and limited load-bearing capacity, making it prone to damage when encountering heavier wind turbine main shafts, thus presenting certain shortcomings. Therefore, we propose a support device for wind turbine main shaft docking. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a support device for connecting wind turbine main shafts, including a base, a support rod, a cylinder, a top seat, an adjusting rod, and a reinforcing component. The support rod is arranged at the top of the base, the cylinder is rotatably connected to the support rod, the top seat is arranged at the top of the support rod, and the top of the top seat is provided with scale lines. The adjusting rod is rotatably connected inside the top seat. The reinforcing component includes a retainer inserted into the top seat, a fastening knob threaded to the outside of the retainer, a fixed shaft arranged inside the retainer, and a rotating seat rotatably connected to the fixed shaft.

[0005] Preferably, it further includes a first connector, which includes a connecting rod passing through the support rod and the cylinder, an insertion hole opened on the connecting rod, and a steel wire passing through the insertion hole.

[0006] Preferably, it further includes a second connector, which is disposed on the top of the cylinder, and the second connector has the same structure as the first connector.

[0007] Preferably, the top of the top seat has a groove.

[0008] Preferably, the adjusting rod has a rotating hole for rotation.

[0009] Preferably, it further includes a third connector, which is disposed on the top seat and has the same structure as the first connector.

[0010] Preferably, the rotating seat has a circular hole, and the rotating seat is rotatably connected to the fixed shaft through the circular hole.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: This utility model, by setting a top seat and reinforcing components, can bear a portion of the weight without affecting the use of the support device, exhibiting excellent stability and convenient calibration. It avoids the problem of the wind turbine main shaft not being able to align due to different angles of the two adjusting rods. Simultaneously, by setting a groove, the adjusting rod can be hidden on the top seat for storage. In use, the user can align the retaining bracket of the reinforcing component with the top seat and insert it. After insertion, the user moves the retaining bracket and rotates the rotating seat until the rotating seat abuts against the adjusting rod. After abutment, it can be rotated to tighten. Tighten the knob until it abuts against the top seat to secure the reinforcement component. Once secured, the reinforcement component can bear part of the weight, providing excellent stability. You can check the scale lines on the edge of the mounting bracket to see if the two adjusting rods are at the same angle to the top seat. When the angles are the same, the device is working properly. When the angles are different, the device cannot fix the wind turbine main shaft in the middle position, which will cause the wind turbine main shaft to shift and cause a misalignment problem. When not in use, the two adjusting rods can be rotated into the groove to hide them for storage. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a support device for connecting wind turbine main shafts.

[0028] Example 1:

[0029] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a support device for connecting wind turbine main shafts, including a base 100, a support rod 200, a cylinder 300, a first connecting member 400, a second connecting member 500, a top seat 600, an adjusting rod 700, a third connecting member 800, and a reinforcing component 900.

[0030] Specifically, the support rod 200 is installed at the top of the base 100. In use, the support rod 200 is used to connect the base 100 and the top seat 600, providing support.

[0031] Specifically, the cylinder 300 is rotatably connected to the support rod 200. During use, the cylinder 300 can be controlled to extend and retract. The extended cylinder 300 can drive the adjusting rod 700 to rotate upward, thereby adjusting the angle of the adjusting rod 700 to adapt to wind turbine main shafts of different sizes, thus having a wide range of applications.

[0032] Specifically, the first connector 400 includes a connecting rod 401 that passes through the support rod 200 and the cylinder 300, an insertion hole 402 opened on the connecting rod 401, and a steel wire 403 that passes through the insertion hole 402. In use, the connecting rod 401 can be passed through the support rod 200 and the cylinder 300, and then the steel wire 403 can be passed through the insertion hole 402. After passing through, the steel wire 403 can be bent to connect the support rod 200 and the cylinder 300. After connection, the bottom of the cylinder 300 can rotate on the support rod 200 for use.

[0033] Specifically, the second connector 500 is arranged on the top of the cylinder 300. The second connector 500 has the same structure as the first connector 400. In use, the cylinder 300 can be rotated on the adjusting rod 700 through the second connector 500 so that the angle of the adjusting rod 700 can be adjusted through the cylinder 300.

[0034] Specifically, the top seat 600 is located at the top of the support rod 200, and the top of the top seat 600 is provided with a scale line 602. The top of the top seat 600 is provided with a groove 601. In use, the scale line 602 is used to detect whether the two adjusting rods 700 rotate synchronously, while the groove 601 can hide the two adjusting rods 700 for storage.

[0035] Specifically, the adjusting rod 700 is rotatably connected inside the top seat 600. The adjusting rod 700 has a rotating hole 701 for rotation. In use, the adjusting rod 700 can be installed on the top seat 600 through the rotating hole 701. After installation, the adjusting rod 700 can rotate on the top seat 600 so that the adjusting rod 700 can adjust the support.

[0036] Specifically, the third connector 800 is mounted on the top seat 600. The third connector 800 has the same structure as the first connector 400. In use, the third connector 800 allows the adjusting rod 700 to rotate on the top seat 600 so as to adjust the angle of the adjusting rod 700.

[0037] Specifically, the reinforcing component 900 includes a retainer 901 inserted into the top seat 600, a fastening knob 902 threaded to the outside of the retainer 901, a fixed shaft 903 located inside the retainer 901, and a rotating seat 904 rotatably connected to the fixed shaft 903. The rotating seat 904 has a circular hole 905, through which it is rotatably connected to the fixed shaft 903. In use, the user aligns the retainer 901 of the reinforcing component 900 with the top seat 600 and inserts it. After insertion, the user moves the retainer 901 and rotates the rotating seat 904 until the rotating seat 904 aligns with the adjusting rod 700. After contact, rotate the fastening knob 902 until it contacts the top seat 600. This will fix the reinforcing component 900 onto the top seat 600. Once fixed, the reinforcing component 900 can bear part of the weight, providing good stability. You can also check the scale line 602 corresponding to the edge of the card holder 901 to see if the angle between the two adjusting rods 700 and the top seat 600 is the same. When the angles are the same, it means the device is working normally. When the angles are different, it means the device cannot fix the wind turbine main shaft in the middle position, which will cause the wind turbine main shaft to shift and cause a problem with docking.

[0038] The working principle and usage process of this utility model are as follows: In use, the user aligns the retainer 901 of the reinforcing component 900 with the top seat 600 and inserts it. After insertion, the user moves the retainer 901 and rotates the rotating seat 904 until the rotating seat 904 abuts against the adjusting rod 700. After abutting, the user rotates the fastening knob 902 until it abuts against the top seat 600, thus fixing the reinforcing component 900 onto the top seat 600. After fixing, the reinforcing component 900 can bear a portion of the weight, providing stability. The device has good stability and can be checked by looking at the scale line 602 corresponding to the edge of the card holder 901. The scale line 602 can be used to determine whether the angle between the two adjusting rods 700 and the top seat 600 is the same. When the angle is the same, it means that the device is working normally. When the angle is different, it means that the device cannot fix the wind turbine main shaft in the middle position, which will cause the wind turbine main shaft to shift and cause the problem of non-connection. When not in use, the two adjusting rods 700 can be rotated into the groove 601 to hide the two adjusting rods 700 for storage.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
