Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine blade cutting equipment, specifically a wind turbine blade cutting device. Background Technology

[0002] Wind turbine blades need to be cut and recycled after they reach their designed service life or are damaged. This process requires the use of specialized cutting equipment.

[0003] A search revealed that CN205888252U discloses a wire saw cutting device for wind turbine blades, comprising a wire saw main unit, a tooling frame, a first hydraulic pump, and a second hydraulic pump. Specifically, the tooling frame has a traveling section at its lower end and a push rod perpendicular to the plane of the tooling frame at its side end. One end of the push rod is fixed to the tooling frame, and the other end is equipped with a handle. At least two sets of guide wheels for winding the cutting rope are mounted on the push rod—all guide wheel sets are on the same plane, which is perpendicular to the plane of the tooling frame but does not intersect with it. Simultaneously, fastening buckles are installed at the upper and lower ends of the tooling frame, and two support plates perpendicular to the plane of the tooling frame are located on the side opposite to the push rod. The wire saw main unit is fixed to the tooling frame and connected to the first and second hydraulic pumps via hydraulic pipes.

[0004] However, the aforementioned wire saw cutting equipment for wind turbine blades has significant shortcomings in actual wind turbine blade cutting operations: after each section of wind turbine blade is cut, the cutting rope must be manually reattached to the blade before the next cutting operation can begin. This process is not only cumbersome but also significantly increases manpower and time consumption, affecting overall cutting efficiency. Utility Model Content

[0005] This utility model provides a wind turbine blade cutting device to solve the following problems mentioned in the background art regarding the wire saw cutting equipment used for wind turbine blades: the operation process is not only cumbersome, but also significantly increases manpower input and operation time, affecting the overall cutting efficiency.

[0006] To address the existing problems, this utility model provides a wind turbine blade cutting device, including a base, a pair of support arms symmetrically arranged above the base, the lower end of the support arms being fixedly connected to the base, the upper end of the support arms being fixedly connected to the lower end of a limiting frame, a lifting and cutting assembly being installed on the limiting frame, and a feeding assembly being provided on one side of the limiting frame.

[0007] The lifting and cutting assembly includes a mounting frame, with both ends of the mounting frame slidably connected to a limiting frame. Auxiliary wheels are rotatably connected to the mounting frame near its upper and lower ends, respectively. A drive wheel is mounted in the middle of the upper end of the mounting frame, and two tension wheels are symmetrically arranged above the drive wheel, both of which are rotatably connected to the mounting frame. The auxiliary wheels, drive wheel, and tension wheels are connected via a cutting rope. The drive wheel is connected to the output shaft of a drive motor fixed to the surface of the mounting frame. A fixing member is provided on the outside of the limiting frame, and the fixing member is fixedly connected to the side end of the mounting frame. A fixing block is fixed to the side end of the limiting frame, and a first hydraulic cylinder connects the fixing member and the fixing block.

[0008] The feeding assembly includes two fixed plates, a row of rotating rollers is rotatably connected between the two fixed plates, a support beam is fixedly connected to the lower end of the fixed plates, and a vertically upward clamping mechanism is provided on the fixed plate near the limiting frame.

[0009] Furthermore, the clamping mechanism includes a frame whose lower end is fixed to a fixed plate, a sliding roller rotatably connected to the lower inner side of the frame, second sliding grooves opened on the two side walls of the frame, a pressure plate provided inside the frame, the two ends of the pressure plate slidably connected to the second sliding groove, and the upper end of the pressure plate and the lower end of the frame respectively connected to the two ends of the second hydraulic cylinder.

[0010] Furthermore, the limiting frame has a first sliding groove on its two inner sidewalls, and the first sliding groove is adapted to the side end of the mounting frame.

[0011] Furthermore, a reinforcing plate is fixedly connected between the lower end of the frame and the support beam.

[0012] Furthermore, the rollers are arranged vertically.

[0013] Furthermore, both the first and second hydraulic cylinders are powered by an oil pump.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This device, by setting up a feeding assembly and a lifting and cutting assembly, allows the lifting and cutting assembly to move downwards along the first slide groove of the limiting frame under the drive of the first hydraulic cylinder. Simultaneously, it drives the cutting rope, which is co-driven by the drive wheel, auxiliary wheel, and tension wheel, to complete the single-segment cutting of the fixed wind turbine blade. After cutting, the lifting and cutting assembly resets. The operator only needs to push the blade forward along the rotating roller of the feeding assembly to the next cutting position. The second hydraulic cylinder of the clamping mechanism drives the pressure plate to fix the blade again, and then the lifting and cutting assembly moves downwards again to cut the blade. Compared with existing technologies, this process eliminates the need for manual reset, adjustment, or re-attaching of the cutting rope, significantly simplifying the operation steps, effectively shortening the auxiliary waiting time for a single cut, and improving the overall efficiency of wind turbine blade cutting operations.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A wind turbine blade cutting device includes a base 1, a pair of support arms 2 symmetrically arranged above the base 1, the lower end of the support arm 2 is fixedly connected to the base 1, the upper end of the support arm 2 is fixedly connected to the lower end of the limiting frame 3, a lifting cutting assembly 4 is installed on the limiting frame 3, and a feeding assembly 5 is provided on one side of the limiting frame 3.

[0023] The lifting and cutting assembly 4 includes a mounting frame 401, with both ends of the mounting frame 401 slidably connected to the limiting frame 3. Auxiliary wheels 402 are rotatably connected to the mounting frame 401 near its upper and lower ends, respectively. A drive wheel 403 is mounted in the middle of the upper end of the mounting frame 401. Two tension wheels 404 are symmetrically arranged above the drive wheel 403, and both tension wheels 404 are rotatably connected to the mounting frame 401. The auxiliary wheels 402, drive wheel 403, and tension wheels 404 are connected via a cutting rope 405. The drive wheel 403 is connected to the output shaft of a drive motor 409 fixed to the surface of the mounting frame 401. A fixing member 406 is provided on the outside of the limiting frame 3, and the fixing member 406 is fixedly connected to the side end of the mounting frame 401. A fixing block 407 is fixed to the side end of the limiting frame 3, and a first hydraulic cylinder 408 is connected between the fixing member 406 and the fixing block 407.

[0024] It should be noted that there are two first oil cylinders 408. The oil pipes of the two first oil cylinders 408 are connected to the oil pump through a synchronization valve, so that the two first oil cylinders 408 can operate synchronously.

[0025] The feeding assembly 5 includes two fixed plates 501, a row of rotating rollers 502 is rotatably connected between the two fixed plates 501, a support beam 503 is fixedly connected to the lower end of the fixed plate 501, and a vertically upward clamping mechanism 504 is provided on the fixed plate 501 near the limit frame 3.

[0026] The clamping mechanism 504 includes a frame 5041 whose lower end is fixed to a fixed plate 501. A sliding roller 5042 is rotatably connected to the lower inner side of the frame 5041. Second sliding grooves 5043 are provided on both side walls of the frame 5041. A pressure plate 5044 is provided inside the frame 5041. The two ends of the pressure plate 5044 are slidably connected to the second sliding grooves 5043. The upper end of the pressure plate 5044 and the lower end of the frame 5041 are respectively connected to the two ends of the second hydraulic cylinder 5045.

[0027] The limiting frame 3 has a first sliding groove 301 on its two inner side walls, which is adapted to the side end of the mounting frame 401.

[0028] Among them, a reinforcing plate 6 is fixedly connected between the lower end of the frame 5041 and the support beam 503.

[0029] Among them, the sliding rollers 5042 are vertically distributed.

[0030] Both the first hydraulic cylinder 408 and the second hydraulic cylinder 5045 are powered by an oil pump.

[0031] Working principle: Before operation, the wind turbine blade to be cut is placed on the rotating roller 502 of the feeding assembly 5. The wind turbine blade is pushed to move along the direction of the lifting and cutting assembly 4 on the rotating roller 502 until the part of the blade to be cut is below the cutting rope 405 of the lifting and cutting assembly 4. At this time, the second hydraulic cylinder 5045, powered by an oil pump, in the clamping mechanism 504 is activated. The second hydraulic cylinder 5045 pushes the pressure plate 5044 to slide downward along the second sliding grooves 5043 on both sides of the frame 5041, pressing and fixing the upper surface of the wind turbine blade to prevent displacement during cutting. Then, the drive motor 409 is activated, and its output shaft drives the drive wheel 403 in the middle of the upper end of the mounting bracket 401 to rotate. The drive wheel 403 drives the cutting rope 405 to rotate in cooperation with the auxiliary wheel 402 and the symmetrically arranged tensioning wheels 404. Subsequently, the first hydraulic cylinder 408, also powered by an oil pump, is activated. The piston rod of the first hydraulic cylinder 408 extends and retracts, causing the fixing member 406 to move downward. Since the fixing member 406 is fixed to the side end of the mounting bracket 401, and the mounting bracket 401 is fixed to the side end of the frame, the first hydraulic cylinder 408 is activated. The mounting frame 401 is slidably connected to the first slide groove 301 on the inner side wall of the limiting frame 3 via its side end. The mounting frame 401 will move downward along the first slide groove 301, thereby driving the cutting rope 405 to descend synchronously. The cutting rope 405 will cut the fixed wind turbine blade. During the cutting process, the first hydraulic cylinder 408 will slowly move downward until the cutting rope 405 cuts a section of the wind turbine blade. Then, the first hydraulic cylinder 408 and the second hydraulic cylinder 5045 will rise and reset, pushing the wind turbine blade forward along the rotating roller 502, so that the position of the wind turbine blade to be cut is below the cutting rope 405. The second hydraulic cylinder 5045 pushes the pressure plate 5044 to descend again to press down the wind turbine blade. Then, the lifting and cutting assembly 4 descends again to complete the cutting.
