Description

Technical Field

[0001] The invention relates to the technical field of wind turbine blade processing, and in particular to a curing furnace profile support device for post-curing heating of wind turbine blades. Background Art

[0002] With the continuous development of the wind power industry and the increasingly stringent requirements on the output of blades, the production efficiency of blades has become a major problem in production. A curing furnace is required for post-curing of blades, that is, a blade is placed upright in a template that matches the blade profile, and is pushed into the curing furnace using a furnace trolley for heating and curing. Each curing furnace is equipped with a furnace trolley.

[0003] However, because it only has one type of profile, it cannot cope with the curing of multiple types of blades in production. Each curing oven can only meet the curing of one blade type, and it is impossible to achieve rapid switching and rapid curing of blade types. When curing multiple blade types, the profile needs to be repeatedly disassembled and assembled, resulting in slow blade circulation and reduced production efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a curing furnace plate support device for post-curing heating of wind turbine blades, which supports and fixes blades of different models by quickly switching between different plates to increase the rotation speed of the blades.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A curing furnace profile support device for post-curing heating of wind turbine blades, characterized in that it comprises:

[0007] A plurality of support seats are arranged on the furnace car at intervals along the axial direction of the blade, and the top of each support seat has a steering support plate arranged along the chord direction of the blade, and the steering support plate can be turned over and locked along the rotating axis in the chord direction;

[0008] Each support base has:

[0009] A fixing seat, capable of being fixed on the steering support plate, having two cavities perpendicular to each other; and

[0010] The mold plate is fixed in each mold cavity. The outer end of the mold plate extending out of the mold cavity has an arc groove matching the blade profile. The arc grooves on the two mold plates in the same fixed seat match the blade profiles of two models.

[0011] A further technical solution is that the steering support plate of each support seat has columns No. I, No. II, No. III and No. V arranged in equal intervals in the chord direction;

[0012] A fixing seat is provided between the No. Ⅰ column and the No. Ⅱ column, which is the No. Ⅰ fixing seat. The No. Ⅰ fixing seat is rotatably connected to the No. Ⅱ column, can be locked with the No. Ⅰ column, and can be locked with the No. Ⅲ column after rotating along the No. Ⅱ column;

[0013] A fixing seat is provided between the No. II column and the No. III column, which is the No. II fixing seat. The No. II fixing seat is rotatably connected to the No. III column, can be locked with the No. II column, and can be locked with the No. V column after rotating along the No. III column;

[0014] The arc grooves on the four mold plates on the No. Ⅰ fixing seat and the No. Ⅱ fixing seat match the blade profiles of four types.

[0015] A further technical solution is that the structures of the No. Ⅰ column, No. Ⅱ column, No. Ⅲ column and No. Ⅴ column are the same, with an annular groove at the bottom and a radially protruding limit plate at the middle;

[0016] A rotating ring is fixed on one side of the fixed seat, and the rotating ring is rotatably assembled in the annular groove through a bearing. A lifting ring is connected to the other side of the fixed seat so as to slide up and down. The lifting ring can be put on or off the corresponding column No. I, column No. II, column No. III or column No. V by sliding up and down, and is limited downward by a limiting plate.

[0017] A further technical solution is that an electromagnetic suction cup is fixed on the top of the limit plate, and the electromagnetic suction cup can be adsorbed and locked with the lifting ring after being energized.

[0018] A further technical solution is that the support seat includes two directional support plates arranged at intervals along the chord direction of the blade, and the steering support plate is horizontally located above the two directional support plates, and its two ends are rotatably connected and lockable to the corresponding directional support plates through a chord-wise rotating shaft.

[0019] A further technical solution is that the steering support plate and the furnace car are connected via a telescopic rod with a locking function, and both ends of the telescopic rod are hinged and fixed to the steering support plate and the furnace car respectively.

[0020] A further technical solution is that the telescopic rod is an electric telescopic rod, a pneumatic cylinder or an oil cylinder.

[0021] A further technical solution is that each steering support plate is locked by two telescopic rods, and the two telescopic rods are respectively placed at two ends of the steering support plate.

[0022] A further technical solution is that the two telescopic rods are arranged in an eight-shaped shape.

[0023] A further technical solution is that the mold plate is located in the mold cavity and is fixed by at least two groups of bolt and nut assemblies penetrating the fixing seat.

[0024] A further technical solution is that an elastic buffer layer is fixed on the supporting surface of the arc-shaped groove.

[0025] The beneficial effects of adopting the above technical solution are:

[0026] The device sets two different types of templates arranged at 90 degrees on the steering support plate of each support seat, so that the two types of leaf-shaped templates can be placed upright or horizontally, one for backup and the other for use. Then, by driving the steering support plate to flip, the templates can be quickly switched, so that blades of different types can be switched into the curing oven for rapid curing, thereby increasing the speed of blade circulation, reducing the waiting time for blades, and quickly achieving the production capacity target.

[0033] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Embodiment 1

[0036] like Figure 1 , Figure 2 and Figure 5As shown, the curing furnace template support device for post-curing heating of wind turbine blades disclosed in the present invention includes a plurality of support seats, each of which is provided with a fixing seat 20 and a template 30 .

[0037] Multiple support seats are arranged on the furnace car at intervals along the axial direction of the blade to support different profiles of the same blade. Generally, 7 support seats are used to support one wind turbine blade, and the number of support seats is adjusted according to the size of the wind turbine blade.

[0038] The support seat includes two directional support plates 12 arranged at intervals along the chord direction of the blade, and a steering support plate 11 arranged along the chord direction of the blade is provided on the top of the two directional support plates 12. The horizontal ends of the steering support plate 11 are rotatably connected and lockable with the corresponding directional support plates 12 through a chord-wise rotating shaft.

[0039] The steering support plate 11 is connected to the furnace car through a telescopic rod 13 with a locking function. The telescopic rod 13 can be an electric telescopic rod 13, a cylinder or an oil cylinder. The two ends of the telescopic rod 13 are respectively hinged and fixed to the steering support plate 11 and the furnace car. The telescopic rod 13 can drive the steering support plate 11 to flip along the rotating axis and lock it after rotating 90 degrees.

[0040] Furthermore, each steering support plate 11 is locked by two telescopic rods 13, which are disposed at both ends of the steering support plate 11 and arranged in an eight-shaped shape. When the steering support plate 11 is turned over along the rotating shaft, one telescopic rod 13 is extended and the other telescopic rod 13 is retracted. The two telescopic rods 13 are arranged in an eight-shaped shape, which makes the support and locking of the steering support plate 11 more reliable.

[0041] The fixing seat 20 is fixed to the steering support plate 11 by bolts or welding. The fixing seat 20 has two mutually perpendicular cavities, one of which is arranged parallel to the steering support plate 11. A mold plate 30 is fixed in each cavity. The mold plate 30 is fixed by at least two sets of bolt and nut assemblies penetrating the fixing seat 20. The outer end of the mold plate 30 extending out of the cavity has an arc groove matching the blade profile. The arc grooves on the two mold plates 30 in the same fixing seat 20 match the blade profiles of the two models. In addition, an elastic buffer layer 31, such as foam, is fixed on the supporting surface of the arc groove to prevent damage from collision with the blade.

[0042] The device arranges two different types of templates 30 arranged at 90 degrees on the steering support plate 11 of each support seat, so that the two types of leaf-shaped templates 30 can be placed upright and horizontally, one for backup and the other for use. Then, by driving the steering support plate 11 to flip, the templates 30 can be quickly switched, so that blades of different types can be switched into the curing oven for rapid curing, thereby increasing the speed of blade circulation, reducing the waiting time of blades, and quickly achieving the production capacity target.

[0043] Embodiment 2

[0044] like Figure 3 and Figure 4 As shown, the curing furnace profile support device for post-curing heating of wind turbine blades disclosed in the present invention is optimized on the basis of the first embodiment, and can support four different types of blades by switching.

[0045] In this embodiment, on the steering support plate 11 of each support seat, there are columns 111, 112, 113 and 114 arranged in equal intervals in the chord direction. There is a fixed seat between columns 111 and 112, which is a fixed seat 20A. The fixed seat 20A is rotatably connected to column 112, can be locked with column 111, and can be locked with column 113 after rotating along column 112. There is a fixed seat between columns 112 and 113, which is a fixed seat 20B. The fixed seat 20B is rotatably connected to column 113, can be locked with column 112, and can be locked with column 114 after rotating along column 113. The arc grooves on the four mold plates 30 on the No. Ⅰ fixing seat 20A and the No. Ⅱ fixing seat 20B match the profiles of the four types of blades.

[0046] Among them, the structures of the No. Ⅰ column 111, the No. Ⅱ column 112, the No. Ⅲ column 113 and the No. Ⅴ column 114 are the same, with an annular groove at the bottom and a radially protruding limit plate 115 at the middle. A rotating ring 202 is fixed on one side of the fixed seat 20. The rotating ring 202 on the No. Ⅰ fixed seat 20A is rotatably assembled in the annular groove on the No. Ⅱ column 112 through a bearing to achieve a rotatable connection with the No. Ⅱ column 112; the rotating ring 202 on the No. Ⅱ fixed seat 20B is rotatably assembled in the annular groove on the No. Ⅲ column 113 through a bearing to achieve a rotatable connection with the No. Ⅲ column 113. A vertical slide groove 201 is provided on the other side of the fixed seat 20, and a lifting ring 203 is connected to the slide groove 201 so as to slide up and down. The lifting ring 203 on the No. Ⅰ fixed seat 20A can be mounted on the No. Ⅰ column 111 or the No. Ⅲ column 113, and the lifting ring 203 on the No. Ⅱ fixed seat 20B can be mounted on the No. Ⅱ column 112 or the No. Ⅴ column 114, and the lifting ring 203 is limited downward by the limit plate 115.

[0047] In addition, an electromagnetic suction cup 116 is fixed on the top of the limiting plate 115 . The electromagnetic suction cup 116 can be adsorbed and locked with the lifting ring 203 after being energized, so that the state of the fixing seat 20 is more stable.

[0048] The position between the column II 112 and the column III 113 is the working position, and the fixing seat 20 in the working position supports the blades. Figure 3The initial position is shown, at which time the blades are supported by the template 30 on the No. II fixing seat 20B. When the No. I fixing seat 20A needs to be switched to the working position, the lifting ring 203 on the No. II fixing seat 20B is first moved up along the slide slot 201 to get out of the No. II column 112, and then the No. II fixing seat 20B is driven to rotate 180° along the No. III column 113, and then the lifting ring 203 on the No. II fixing seat 20B is sleeved on the No. V column 114, so that the No. II fixing seat 20B is fixed between the No. III column 113 and the No. V column 114, and the working position is made available. Then, in the same way, the No. I fixing seat 20A is rotated 180° along the No. II column 112 to the working position, at which time the template 30 on the No. I fixing seat 20A can be used to support the blades. To achieve chord-wise switching of the No. Ⅰ fixing seat 20A and the No. Ⅱ fixing seat 20B, when it is necessary to flip the steering support plate 11 to switch the template 30, the No. Ⅰ fixing seat 20A and the No. Ⅱ fixing seat 20B can be reset to the initial state first, thereby achieving switching of the four templates 30.

[0049] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent substitution made by anyone to the present invention based on the contents of the present invention shall fall within the protection scope of the present invention.
