Description

Technical Field

[0001] This utility model relates to the field of placement device technology, and in particular to a wind tower placement device. Background Technology

[0002] Against the backdrop of the global energy structure transitioning towards clean energy, wind power, as a mature renewable energy utilization method, has seen its industry scale continue to expand. As the core load-bearing component of wind turbine generators, the wind tower needs to have sufficient structural strength to support equipment such as the nacelle and blades. Therefore, it is relatively large in size and heavy in weight. During the production and pretreatment of the wind tower, it is necessary to rely on a special placement device to achieve stable support. This device must not only ensure that the tower does not deform during placement but also provide safe and convenient operating conditions for subsequent operations. Therefore, the rationality and stability of the tower placement device are crucial to the production efficiency and safety management of wind towers.

[0003] Existing wind turbine tower placement devices still have the following drawbacks in practical applications: Existing devices mostly support the bottom of both ends of the tower only through two or more sets of roller frames, without setting an effective auxiliary support structure for the top of the tower. Due to the slender cylindrical structure of the tower, the overall center of gravity is relatively high. When there are external environmental disturbances, such as wind in the factory area, slight collisions with hoisting equipment, or asynchronous rotation of the roller frames due to different drives, the tower may shift laterally or even overturn. This may not only cause damage to the tower body, but also pose a serious safety hazard. Therefore, this utility model proposes a wind tower placement device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind turbine tower placement device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wind turbine tower placement device includes a roller frame, on the top surface of which a tower is placed. It also includes a support assembly for supporting the top of the tower, the support assembly being disposed on one side of the roller frame. The support assembly includes a support platform, which is disposed on one side of the roller frame. A vertical support steel structure is fixedly installed on the top surface of the support platform. Lateral reinforcing steel structures are fixedly installed on both sides of the vertical support steel structure, and the lateral reinforcing steel structures are fixedly installed to the support platform. A first circular through hole is formed on the top surface of the lateral reinforcing steel structure. A first hydraulic cylinder is fixedly sleeved on the inner circular wall of the hole. A support frame is movably sleeved on the outside of the vertical support steel structure. Several rotating wheels are installed on both sides of the inside of the support frame. The rotating wheels abut against the inner and outer side walls of the vertical support steel structure. The top surface of the telescopic shaft of the first hydraulic cylinder is connected to the bottom surface of the support frame. A double wheel frame is fixedly installed on one side of the support frame. The rollers of the double wheel frame are supported on the inner side wall of the tower. An adjustment mechanism is provided on one side of the roller frame for adjusting the distance between the roller frame and the support frame.

[0006] As a further embodiment of this utility model, the adjusting mechanism includes: a connecting pipe, the connecting pipe being fixedly installed on one side of the roller frame, a connecting U-shaped pipe being movably sleeved inside the connecting pipe, the connecting U-shaped pipe being fixedly installed with the support frame, a second hydraulic cylinder being connected to one side of the support frame, and the other end of the second hydraulic cylinder being connected to one side of the roller frame.

[0007] As a further embodiment of this utility model, an inclined support steel structure is fixedly installed on one side of the vertical support steel structure, and the inclined support steel structure is fixedly installed on the top surface of the support platform.

[0008] As a further embodiment of this utility model, the bottom surface of the roller frame is provided with two tracks, through which the support frame is supported and moved.

[0009] As a further embodiment of this utility model, a limiting top plate is fixedly installed on the top surface of the vertical support steel structure.

[0010] As a further embodiment of this utility model, both the vertical support steel structure and the lateral reinforcement steel structure are made of steel.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, by setting a targeted tower top support component, can drive the double-wheel frame to abut against the inner wall of the tower top and form a stable support, overcoming the structural defects of existing technologies that only support the bottom of the tower, and significantly reducing the risk of tipping over due to the high center of gravity. Even in the case of asynchronous rotation of the roller frames or slight external disturbances, the stability of the tower placement can still be guaranteed, providing a safety guarantee for tower pretreatment operations and long-term storage.

[0012] 2. The horizontal distance between the roller frame and the support platform can be flexibly adjusted using an adjustment mechanism. Simultaneously, the support frame is moved up and down via a first hydraulic cylinder, allowing for adaptation of the double-roller frame support height. This adapts to towers of different diameters, enhancing the device's applicability in various tower production scenarios. The dual reinforcement design of the lateral and diagonal support steel structures disperses concentrated stress generated during support to the support platform and the ground, preventing bending and tipping accidents.

[0018] Reference Figures 1-6 A wind turbine tower placement device includes a roller frame 1, on the top surface of which a tower 2 is placed. It also includes a support assembly for supporting the top of the tower 2, the support assembly being disposed on one side of the roller frame 1. The support assembly includes a support platform 3, which is disposed on one side of the roller frame 1. A vertical support steel structure 4 is fixedly installed on the top surface of the support platform 3. Lateral reinforcing steel structures 5 are fixedly installed on both sides of the vertical support steel structure 4. The lateral reinforcing steel structures 5 are fixedly installed to the support platform 3. A first circular through hole is formed on the top surface of the lateral reinforcing steel structure 5. A first hydraulic cylinder 6 is fixedly sleeved on the inner circular wall. A support frame 7 is movably sleeved on the outside of the vertical support steel structure 4. Several rotating wheels 8 are installed on both sides of the inside of the support frame 7. The rotating wheels 8 abut against the inner and outer side walls of the vertical support steel structure 4, respectively. The top surface of the telescopic shaft of the first hydraulic cylinder 6 is connected to the bottom surface of the support frame 7. A double wheel frame 9 is fixedly installed on one side of the support frame 7. The rollers of the double wheel frame 9 are supported on the inner side wall of the tower 2. An adjustment mechanism is provided on one side of the roller frame 1 for adjusting the distance between the roller frame 1 and the support platform 3.

[0019] In this embodiment, the adjustment mechanism includes: a connecting pipe 10, which is fixedly installed on one side of the roller frame 1. A connecting U-shaped pipe 15 is movably sleeved inside the connecting pipe 10. The connecting U-shaped pipe 15 is fixedly installed with the support frame 3. A second hydraulic cylinder 14 is connected to one side of the support frame 3. The other end of the second hydraulic cylinder 14 is connected to one side of the roller frame 1. An inclined support steel structure 13 is fixedly installed on one side of the vertical support steel structure 4. The inclined support steel structure 13 is fixedly installed on the top surface of the support frame 3. Two rails 11 are provided on the bottom surface of the roller frame 1. The support frame 3 is supported and moved by the rails 11. A limiting top plate 12 is fixedly installed on the top surface of the vertical support steel structure 4. Both the vertical support steel structure 4 and the lateral reinforcing steel structure 5 are made of steel.

[0020] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: When the tower 2 is supported by the roller frame 1, the tower 2 is hoisted and placed on the top surface of the roller frame 1. Generally, the tower 2 is supported at both ends by two roller frames 1. After placement, the second hydraulic cylinder 14 is retracted to pull the support platform 3 to move, so that the support platform 3 moves and drives the double wheel frame 9 into the interior of the tower 2. Then, the two first hydraulic cylinders 6 are activated to push the support frame 7 to move upward under the support of the rotating wheel 8, so that the double wheel frame 9 is pressed against the inner wall of the tower 2.

[0021] This allows the tower 2 to support the inner top wall when rotating, preventing accidents such as the tower 2 tipping over due to an excessively high center of gravity or asynchronous rotation of the roller frame 1. Even if the roller frame 1 rotates asynchronously or there is slight external disturbance, the stability of the tower 2 can still be guaranteed, providing a safety guarantee for the pre-treatment operation and long-term storage of the tower 2, which is quite practical.

[0022] The vertical support steel structure 4 is reinforced by the inclined support steel structure 13 and the lateral reinforcement steel structure 5. The bottom of the support platform 3 is supported by the connecting pipe 10 and the second hydraulic cylinder 14. The concentrated stress generated during the support process can be distributed to the support platform 3, the roller frame 1 and the ground to prevent bending and tilting accidents, and to prevent the support platform 3 from tilting towards the tower 2.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
