Description

Technical Field

[0001] This utility model relates to the field of transport base technology, and in particular to a transport base for a wind turbine hub. Background Technology

[0002] The transport base is used to support and fix the wind turbine hub during transport. The transport base consists of a base, mounting holes, a support platform, and fixing holes. When using the transport base to transport a small wind turbine hub, the base is placed on the transport vehicle, and then the mounting holes are aligned with the mounting slots on the transport vehicle. Then, bolts are used to fix the base to the transport vehicle. Next, the wind turbine hub is lifted onto the support platform by a crane. Then, the round holes and fixing holes on the wind turbine hub are aligned horizontally and vertically, and bolts are used to fix them, thereby supporting and fixing the wind turbine hub. Finally, the transport vehicle can transport the wind turbine hub.

[0003] In their daily work, the inventors discovered that when using the transport base, the wind turbine hub is placed on the support platform, and then the round hole on the wind turbine hub is aligned horizontally and vertically with the fixing hole on the support platform. However, because the wind turbine hub is very heavy, it is difficult to adjust the position of the wind turbine hub after it is placed on the support platform, which may affect the transport support and fixing efficiency of the transport base and the wind turbine hub. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, when the wind turbine hub is placed on the support platform and the circular hole on the wind turbine hub is aligned horizontally and vertically with the fixing hole on the support platform, it is difficult to adjust the position of the wind turbine hub after it is placed on the support platform because the wind turbine hub is very heavy. This may affect the efficiency of transport base and wind turbine hub transport support and fixing. Therefore, a transport base for wind turbine hub is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a transport base for a wind turbine hub, comprising a base, a support platform fixedly connected to the upper end of the base, an installation hole provided at the upper end of the base, a fixing hole provided at the upper end of the support platform, an auxiliary component provided at the upper end of the support platform, the auxiliary component comprising a rotating block rotatably connected to the support platform by means of a bearing, and a drive mechanism for driving the rotating block to rotate provided on the inner wall of the support platform.

[0006] The effect achieved by the above components is as follows: when it is necessary to easily adjust the wind turbine hub, the wind turbine hub is placed on the rotating block, and then the rotating block is rotated by the drive mechanism. The adjustment is made so that the round hole on the wind turbine hub is horizontally and vertically aligned with the fixing hole on the support platform. Then, bolts are used to fix it, thereby facilitating the adjustment of the wind turbine hub as much as possible.

[0007] Preferably, the driving mechanism includes a gear ring fixedly connected to the inner wall of the rotating block, and the inner arc surface of the gear ring is meshed with a gear.

[0008] The effect achieved by the above components is that the gear rotates, causing the gear ring to rotate, and the rotating block to rotate.

[0009] Preferably, a mounting plate is fixedly connected to the inner arc surface of the support platform, and a motor is installed at the lower end of the mounting plate, the motor controlling the rotation of the gears.

[0010] The effect achieved by the above components is as follows: the motor at the lower end of the mounting plate is started, the motor is connected to the gear through the reducer and coupling, and the gear rotates.

[0011] Preferably, ball bearings are provided between the support platform and the rotating block.

[0012] The effect achieved by the above components is to support the rotating block by setting ball bearings.

[0013] Preferably, the upper end of the base is provided with a pre-fixing component, which includes a pressure plate disposed on the upper end of the support platform.

[0014] The effect achieved by the above components is as follows: after the round hole on the wind turbine hub and the fixing hole on the support platform are horizontally and vertically aligned, the pressure plate of the pushing mechanism is pressed onto the wind turbine hub to pre-fix it, and then bolts are used to fix it.

[0015] Preferably, a round rod is fixedly connected to the upper end of the base, and a lead screw is provided at the upper end of the base via a bearing for rotatable connection. The pressure plate and the lead screw are threadedly connected, and the pressure plate slides on the round rod.

[0016] The effect achieved by the above components is that, by rotating the lead screw and restricting it with the round rod, the pressure plate presses against the hub of the wind turbine.

[0017] Preferably, a rod is inserted into the front of the pressure plate, the rod has a protrusion on its arc surface, and the arc surface of the rod has multiple evenly distributed positioning grooves.

[0018] The effect achieved by the above components is to fix the pressure plate by inserting the rod into the positioning groove.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by means of an auxiliary component, when it is necessary to conveniently adjust the wind turbine hub, the wind turbine hub is placed on the rotating block, and then the rotating block is rotated by the drive mechanism. The adjustment is made so that the round hole on the wind turbine hub and the fixing hole on the support platform are horizontally and vertically aligned, and then bolts are used to fix it, thereby achieving the effect of facilitating the adjustment of the wind turbine hub as much as possible.
