Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blade flash cutting devices, in particular to a suspension device for wind turbine blade follow-up edge cutting equipment. Background Art

[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electrical energy, and are also the main basis for measuring the design and technical level of wind turbines. Wind turbine blades use glass fiber epoxy resin as the main raw material and vacuum assisted resin transfer molding as the main processing technology. The two semi-shells and shear webs are formed separately, and after secondary bonding and assembly, a complete large wind turbine blade is obtained.

[0003] In the manufacturing process of wind turbine blades, there is a process of closing the upper blade and the lower blade with adhesive. However, after closing the mold, the adhesive and the glass fiber cloth will exceed the outline of the blade. Only after the adhesive that exceeds the outline of the blade is cut, the production requirements can be met. Traditionally, the cutting of the flash is mainly done by manual cutting and polishing. However, manual cutting not only has poor cutting effect, low efficiency, and a harsh working environment, which is extremely harmful to workers, but also cannot accurately cut the flash, resulting in uneven blade burrs. The existing device for cutting the flash of wind turbine blades cuts the flash by setting a disc cutting knife, an adjustment plate, an adjustment spring and a number of brackets to cooperate with each other, thereby replacing the traditional manual cutting in the specific operation process. Although it reduces the loss of labor, other power equipment is required to provide power when cutting the flash. At the same time, when cutting the flash, if the staff is distracted during the work, it will also cause uneven blade burrs and even damage the root of the wind turbine blade mold.

The balancer is connected to the first mounting ring 121. At the same time, the second slide rail 11 and the balancer are both installed on the external wind turbine blade trimming device. The balancer cooperates with the lifting mechanism 10 to realize that the limiting cutting mechanism 30 follows the flash edge to make synchronous up and down movements.

[0029] The position-limiting cutting mechanism 30 includes a cutting assembly 31 and a mounting frame. The cutting assembly 31 includes an upper dust cover 311, a lower dust cover 312 and a cutting blade 313. The cutting blade 313 is controlled by a motor to perform rotational cutting on the flash. The lower dust cover 312 is slidably connected to the lower part of the upper dust cover 311. The cutting blade 313 is installed in the upper dust cover 311, and the end of the cutting blade 313 protrudes from the bottom of the upper dust cover 311 and extends into the lower dust cover 312. The mounting frame includes an upper mounting frame 32 connected to the upper dust cover 311 and a lower mounting frame 33 connected to the lower dust cover 312. The upper mounting frame 32 is connected to a first slide rail 324 through a mounting plate 323. The lower mounting frame 33 is fixedly connected to a first slide seat 325. The first slide rail 324 is connected to the first slide seat 325 and the first slide seat 325 can slide along the first slide rail 324, thereby realizing a sliding connection between the upper mounting frame 32 and the lower mounting frame 33. When the first slide 325 slides downward along the first slide rail 324, the first slide 325 drives the lower mounting frame 33 to slide downward synchronously, and at the same time, the lower dust cover 312 follows the lower mounting frame 33 to make synchronous movement, that is, a certain interval is generated between the upper dust cover 311 and the lower dust cover 312. At this time, the external wind turbine blade trimming equipment is moved toward the side close to the flash until the flash is located between the upper dust cover 311 and the lower dust cover 312. At this time, the first slide 325 is controlled by the cylinder to move toward the side close to the upper mounting frame 32 until the upper mounting frame 32 and the lower mounting frame 33 clamp the flash.

The third roller 322 and the fourth roller 332 clamp the burr from the upper and lower sides. The first roller 321 and the second roller 331 cooperate with the third roller 322 and the fourth roller 332 to clamp the burr, which will not damage the root of the wind turbine blade mold while ensuring the fixing of the burr cutting size, with high cutting accuracy and good effect. In a preferred embodiment, a fifth roller 326 is longitudinally provided on the upper mounting frame 32, the fifth roller 326 is provided with one, and the fifth roller 326 is disposed between the first roller 321 and the cutting assembly 31, and a sixth roller 333 is longitudinally provided on the lower mounting frame 33, the sixth roller 333 is provided with one, and the sixth roller 333 is located directly below the fifth roller 326, and the fifth roller 326 and the sixth roller 333 are flush with the outer end surfaces of the third roller 322 and the fourth roller 332.

[0031] The lifting mechanism 10 is connected to the rotating mechanism, and the rotating mechanism is connected to the limiting cutting mechanism 30. The rotating mechanism includes a first rotating assembly 21, a second rotating assembly 22 and a third rotating assembly 23. The first rotating assembly 21 includes a first outer ring 211, a first inner ring 212 and a first mounting seat 213. The first outer ring 211 is fixedly connected to the second slide 12 and is rotatably connected to the first inner ring 212. The first inner ring 212 is fixedly connected to the first mounting seat 213. The first rotating assembly 21 enables the cutting assembly 31 to make synchronous steering movement along the X axis, which can ensure that the suspension device follows the shape along the length direction of the flash. The second rotating assembly 22 includes a second inner ring 221, a second outer ring 222 and a first connecting frame. The second inner ring 221 is rotatably connected to the second outer ring 222. The second outer ring 222 is fixedly connected to the first connecting frame. The second rotating assembly 22 enables the cutting assembly 31 to make synchronous steering movement along the Z axis. When the distance between the suspension device and the wind turbine blade die-stitching root changes, it can ensure that the distance between the suspension device and the wind turbine blade die-stitching root is consistent. A telescopic assembly 40 is provided between the first rotating assembly 21 and the second rotating assembly 22. The telescopic assembly 40 includes a telescopic cylinder 41 and a second connecting frame 42. The telescopic cylinder 41 is fixedly mounted on the first mounting seat 213.

The telescopic assembly 40 is equivalent to a compressed spring, which pushes the limiting cutting mechanism 30 to a position close to the root of the external wind turbine blade mold clamping position, that is, the limiting cutting mechanism 30 is pressed against the root of the wind turbine blade mold clamping position. The third rotating component 23 includes a bearing 231, which is inserted into the first connecting frame 223 and the upper mounting frame 32 to realize the rotational connection between the first connecting frame 223 and the upper mounting frame 32. The third rotating component 23 realizes the synchronous steering movement of the limiting cutting component 31 along the Y-axis. During the movement, the suspension device is installed on the external wind turbine blade conforming trimming equipment. Due to the uneven road surface, the cutting component 31 may move in the left and right directions. The third rotating component 23 can ensure that the limiting cutting component 31 conforms to the left and right shapes.

[0032] In this embodiment, a third slide rail 421 and a third slide seat 422 are provided on the second connecting frame 42, the third slide rail 421 is fixedly installed on the second connecting frame 42, the third slide seat 422 is connected to the second inner ring 221, and the third slide seat 422 can move along the third slide rail 421, and a plug-in rod is provided on the second connecting frame 42, a first spring 423 and a second spring 424 are inserted into the plug-in rod, a second mounting ring is inserted between the first spring 423 and the second spring 424, and the third slide seat 422 is connected to the second mounting ring. When the external wind turbine blade conforming trimming device is suddenly started or the external wind turbine blade conforming trimming device moves at a faster speed, the cutting speed of the cutting blade 313 cannot keep up with the moving speed of the external wind turbine blade conforming trimming device. At this time, the first spring 423 or the second spring 424 generates elastic support for the slide seat to increase the stability of the device. The first spring 423 and the second spring 424 have the same length, that is, when not in use, the second mounting ring is located in the middle of the plug rod, and the first spring 423 or the second spring 424 provides elastic support to the second mounting ring. When the suspension device cuts off the flash, the first spring 423 and the second spring 424 play a buffering role, so that the cutting speed of the cutting blade 313 is not affected by the external wind turbine blade trimming device even if it is slightly faster or slower. In this embodiment, a collection pipe 5 can also be installed on the lower dust cover 312 to collect the cut droplets.

[0033] When in use, the first slide 325 is first controlled by the cylinder to slide downward, so that the upper dust cover 311 and the lower dust cover 312 are opened a certain distance, and then the suspension device is moved to the flash position and the flash is located between the upper dust cover 311 and the lower dust cover 312. The first slide 325 is then controlled by the cylinder to slide upward, so that the third roller 322 and the fourth roller 332 are tightly clamped from the upper and lower sides of the flash, and at this time, the first roller 321 and the second roller 331 are against the root of the wind turbine blade mold from the upper and lower sides, and the motor controls the cutting blade 313 to rotate and cut the flash.

[0034] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
