Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine transportation equipment, in particular to a clamping device for wind power generation blades. Background Technique

[0002] The design of wind turbine blades directly affects the conversion efficiency of wind energy and its annual power generation. It is an important part of wind energy utilization. Nowadays, the application of wind turbine blades has been very extensive, making great contributions to the power development of today's society. During the transportation of wind turbine blades, clamping devices are needed to fix them to improve the stability of wind power generation blades.

[0003] When the current wind turbine blades are transported, the front end of the blade is fixed to the fixed pile of the transport vehicle through a professional transport vehicle, and the tail of the blade is clamped and supported. Most of the clamping structures at the tail are hoisting clamp structures. When the heavy clamp is disassembled and installed, the operation is very inconvenient and it is easy to scratch the blade. Since the clamp structure is a rigid fixation, during the transportation of the fan blade in mountainous areas, with the operation of the vehicle going up and down slopes, it is easy to cause friction between the blade and the clamp, resulting in scratches. After arriving at the destination, the blade needs to be polished and repaired, increasing the transportation cost and reducing the quality of the blade at the same time. Therefore, a clamping device for wind power generation blades is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamping device for wind power generation blades to solve the problem that the existing wind blade clamping device is easy to cause wear with the blade during installation, disassembly and transportation, thus affecting the service life of wind turbine blades.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A clamping device for wind power generation blades, including a transportation platform, on the upper end surface of which a fixed base, a support platform and a clamping platform are arranged. The support platform is located at the side end surface of the fixed base, and the clamping platform is located at the end far from the fixed base on the upper end surface of the transportation platform. The clamping platform is composed of a support plate and a clamping plate. The clamping plate is rotatably connected to the support plate. Positioning grooves are arranged on the inner end surfaces of the clamping plate and the support plate, and protective air bags are arranged on the inner end surfaces of the positioning grooves. A high-pressure air blower is arranged at the bottom of the support plate.

[0006] Preferably, hydraulic telescopic rods are arranged at the bottoms of the support platform and the clamping platform, which is convenient for adjusting the heights of the support platform and the clamping platform.

[0007] Preferably, the number of the clamping plates is two, and damping hinges are arranged at the edges of the upper end surface of the support plate. The two groups of clamping plates are rotatably connected to the support plate through the damping hinges. The damping hinges reduce the rotation speed of the clamping plates to avoid hitting the equipment too fast.

[0008] Preferably, the protective airbag is made of silica gel material. The bottom of the protective airbag is connected to the high-pressure blower in a through manner, and an exhaust port is provided at the top of the protective airbag. Air is pumped into the protective airbag by the high-pressure blower, so that the protective airbag wraps the generator blade around the center of the clamping table, preventing the wind turbine blade from contacting the clamping table.

[0009] Preferably, a first one-way valve is provided between the protective airbag and the high-pressure blower, and a second one-way valve is provided at the exhaust port.

[0010] Preferably, fixing bolts are provided on the upper end surface of the clamping plate, and the two clamping plates are fixed by the fixing bolts.

[0011] Preferably, a dust-proof cover is provided at the outer end of the high-pressure blower to prevent dust from entering the high-pressure blower.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model replaces the traditional lifting buckle and clamp structure with a flip-type clamping plate structure, so that the clamping table does not need to be lifted by external equipment during fixation, thereby avoiding damage to the equipment or employees during the lifting process of the clamping table, and improving the safety and convenience of the equipment.

[0014] 2. The present utility model is provided with a protective airbag on the inner end surface of the clamping table and a high-pressure blower at the bottom of the clamping table. Air is blown into the protective airbag by the high-pressure blower, so that the protective airbag wraps the generator blade around the center of the clamping table, preventing the wind turbine blade from contacting the clamping table and causing wear of the generator blade, thereby improving the service life of the generator blade.
