Description

Technical Field

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

[0002] As the global wind power industry develops towards large-scale and large-scale production, wind towers, as the core supporting components of wind turbine generators, are mostly cylindrical steel structures with large diameters and long dimensions. After the wind towers are manufactured in the factory, they need to be transported to the wind power construction site and hoisted in sections on site.

[0003] In existing technologies, when transporting and installing the main body of a wind turbine, only the two ends of the turbine are rigidly fixed. There is a lack of effective clamping and support for the middle area of ​​long wind turbines. This causes the middle part to generate large lateral stress due to its own weight and transportation bumps. When encountering unexpected situations such as sudden braking or road bumps, the lateral impact load will increase sharply, affecting the structural stability and making it easy for the turbine to tilt and shift. This seriously affects the safety during transportation, increases construction costs and construction period, and therefore there is an urgent need for a wind turbine installation clamping 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 tower installation clamping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wind turbine mounting clamping device includes a base, on the top surface of which a wind turbine body is mounted, and a clamping assembly for clamping the wind turbine body. The clamping assembly is disposed on the top surface of the base and includes two fixing plates, both of which are fixedly mounted on the top surface of the base. A first fixing hole is formed on the top surface of the base, and a double-eared hydraulic cylinder is disposed inside the first fixing hole. A rotating plate is hinged to the inner circular wall of the telescopic end lug of the double-eared hydraulic cylinder. A first circular through hole is formed on one side of the rotating plate, and a fixing post is movably sleeved on the inner circular wall of the first circular through hole. One end of the fixing post is fixedly mounted to one side of the fixing plate. The rotating plate can rotate about the fixing post as an axis under the pull of the double-eared hydraulic cylinder, and the clamping plate is fixedly mounted on the top surface of the rotating plate.

[0006] As a further embodiment of this utility model, a second fixing hole is provided on each side of the base, a threaded post is inserted into the inner circular wall of the second fixing hole, and a nut is threadedly connected to the outer circular wall of the threaded post.

[0007] As a further embodiment of this utility model, a sleeve is movably sleeved on the outer circular wall of the threaded column, and the sleeve is movably sleeved with the tail end ear of the double-eared oil cylinder.

[0008] As a further embodiment of this utility model, a pin opening is provided on the outer circular wall surface of the threaded column.

[0009] As a further embodiment of this utility model, the top surface of the base is provided with an arc-shaped support groove, which conforms to the curvature of the wind tower body.

[0010] As a further embodiment of this utility model, the top surface of the base is provided with a plurality of mounting holes.

[0011] As a further embodiment of this utility model, a rubber plate is fixedly installed on one side of the clamping plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This device precisely matches the curvature of the wind tower through the arc-shaped support groove, providing full support to the bottom of the wind tower and dispersing vertical gravity. The clamping components on both sides can clamp from the middle of both sides of the wind tower. Compared with the existing method of fixing only the two ends, it improves the efficiency of lateral stress dispersion in the middle area of ​​the wind tower. It can prevent weld cracking and steel structure deformation when encountering unexpected impact loads. At the same time, it avoids position tilting and displacement, avoids affecting the safety during transportation, and reduces subsequent correction costs.

[0013] 2. By using a double-eared hydraulic cylinder and controlling the extension and retraction of the cylinder through a hydraulic control system, the clamping and releasing operation of a set of devices can be completed within minutes. A single person can operate a set of devices simultaneously, improving the efficiency of batch transportation scenarios. The main body of the double-eared hydraulic cylinder is embedded in the first fixing hole inside the base, and the drive component is integrated with the base. The compact design reduces space occupation and is quite practical. Attached Figure Description

[0019] Reference Figures 1-5 A wind turbine mounting clamping device includes: a base 1, a wind turbine body 2 mounted on the top surface of the base 1, and a clamping assembly for clamping the wind turbine body 2. The clamping assembly is mounted on the top surface of the base 1 and includes: two fixing plates 4, both of which are fixedly mounted on the top surface of the base 1. A first fixing hole 8 is provided on the top surface of the base 1. A double-eared hydraulic cylinder 9 is provided inside the first fixing hole 8. A rotating plate 5 is hinged to the inner circular wall of the telescopic end ear of the double-eared hydraulic cylinder 9. A first circular through hole is provided on one side of the rotating plate 5. A fixing post 6 is movably sleeved on the inner circular wall of the first circular through hole. One end of the fixing post 6 is fixedly mounted to one side of the fixing plate 4. The rotating plate 5 can rotate around the fixing post 6 as an axis under the pull of the double-eared hydraulic cylinder 9. A clamping plate 7 is fixedly mounted on the top surface of the rotating plate 5.

[0020] In this embodiment, the base 1 has second fixing holes 10 on both sides. A threaded post 12 is inserted into the inner circular wall of the second fixing hole 10. A nut 13 is threadedly connected to the outer circular wall of the threaded post 12. A sleeve 11 is movably sleeved on the outer circular wall of the threaded post 12. The sleeve 11 is movably sleeved with the tail end ear of the double-eared cylinder 9. A pin 14 is opened on the outer circular wall of the threaded post 12. An arc-shaped support groove 3 is provided on the top surface of the base 1. The arc-shaped support groove 3 fits the outer curvature of the wind tower body 2. Several mounting holes 15 are opened on the top surface of the base 1. A rubber plate 16 is fixedly installed on one side of the clamping plate 7.

[0021] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: When transporting and installing the existing wind tower body 2, it is generally placed and transported using a special vehicle with an arc groove. The two ends of the wind tower body 2 are fixed, but the middle part is less fixed, resulting in greater lateral stress. This may lead to increased lateral force or other directional force loads in case of accidents, which may easily cause damage to the internal structure due to insufficient support. At the same time, it may also cause tilting and displacement.

[0022] To avoid compromising safety during transport, a clamping device is needed for support. With the base 1 in place, when the user needs to transport the wind turbine main body 2, the base 1 is installed on the vehicle body through the mounting holes 15. The vehicle body has a position for installing the base 1, and the width of the base 1 matches the width of the vehicle body. At the same time, the fixing plate 4 matches the outer diameter of the wind turbine main body 2. The fixing plate 4 and the supporting arc groove on the vehicle body are at the same level, so that they can work together to support the wind turbine main body 2. After the wind turbine main body 2 is hoisted into the fixing plate 4 on the top surface of the base 1 for support, the double-ear hydraulic cylinder 9 is activated to push the rotating plate 5 to rotate, which in turn drives the clamping plate 7 to rotate. Then, the clamping plates 7 on both sides clamp the sides of the wind turbine main body 2 like human hands, improving the support effect on both sides of the wind turbine main body 2. When subjected to high lateral loads, it can provide support, avoid structural damage to the wind turbine main body 2, avoid tilting and displacement, and avoid affecting the safety during transportation.

[0023] The rubber plate 16 provides buffer protection between the clamping plate 7 and the main body 2 of the wind tower. The threaded column 12 and the sleeve 11 can be disassembled by turning the nut 13. By setting the main body of the double-ear cylinder 9 inside the base 1, the whole structure is compact and occupies little space, thus avoiding affecting the vehicle's transportation and operation.

[0024] The mounting holes 15 on the top surface of the base 1 are standardized interfaces that can be directly connected to transport vehicles and construction platforms of different specifications without the need for customized adjustments; the arc-shaped support groove 3 and the clamping plate 7 can be flexibly designed according to the diameter of the wind tower body 2, and one set of equipment can be adapted to multiple models of wind tower body 2, reducing procurement costs.

[0025] 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.
