Description

Technical Field

[0001] The present invention relates to the technical field of cutting processing, and particularly relates to a cutting system for a wire saw machine. Background Art

[0002] Wind turbine blades are the core components of wind turbine units and are also an important part of the entire wind power generation industry. During use, due to the influence of comprehensive factors such as their own structure and weather conditions, wind turbine blades generally need to be considered for replacement after 15 - 20 years of service life. When the old blades are replaced, because the overall cost is very high and many of the materials are recyclable materials, from the perspective of environmental protection and energy conservation, it is necessary to recycle and reuse the blades. Considering the overall use environment of wind turbine blades, the overall handling cost is too high and it is not convenient for transportation. Therefore, a new type of blade cutting device is particularly important at this time. Based on the above environment, we need to first cut the wind turbine blades horizontally into sections, and then transport them back to the factory as a whole and cut them vertically into pieces to complete the preliminary recycling and utilization.

[0003] Currently, the device for cutting wind turbine blades using a wire saw machine mainly relies on manual operation. First, the operator places the wire saw machine in the corresponding position, then inserts the wire saw rope into one end of the wind turbine blade, and then makes the wire saw rope loop around the pre-cutting position. After determining the position, the position of the wire saw machine is fixed. Since the wire saw machine is equipped with a guide rail device, after starting the wire saw machine, the wire saw machine will cut the wind turbine blade along the corresponding route. After cutting is completed, at this time, the wire saw rope will fall off. The operator needs to re-insert the wire saw rope into the wind turbine blade, then adjust the position of the wire saw machine to the pre-cutting position, and after fixing the wire saw machine again, start the cutting program.

[0004] The above-mentioned cutting method for wind turbine blades has cumbersome work content. Because the cutting volume of wind turbine blades is too large, it is not only time-consuming and laborious for the operator to insert the wire saw rope into the wind turbine blade, with very low work efficiency, but also each step requires manual adjustment of the position. Therefore, it has become an urgent problem to develop a wire saw machine cutting system that can be applied to the cutting of large parts, does not require manual adjustment of the position of the wire saw rope, and is time-saving, labor-saving, and has high work efficiency.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] A wire saw machine cutting system provided by an embodiment of the present invention, as Figures 1 to 5 shown, includes: a gantry 9, a wire saw machine 6 that drives the movement of a wire saw rope 10, a universal wheel module, and a driving mechanism; the universal wheel module includes a first universal wheel 1 that is horizontally movable and disposed on the upper beam frame 91 of the gantry, a second universal wheel 2 and a fifth universal wheel 5 that are respectively fixedly disposed on the upper and lower parts of the first longitudinal beam frame 94 of the gantry, a third universal wheel 3 and a fourth universal wheel 4 that are horizontally movable and disposed on the lower beam frame 92 of the gantry, and the wire saw rope 10 sequentially winds around the first universal wheel 1, the second universal wheel 2, the wire saw machine 6, the fourth universal wheel 4, the fifth universal wheel 5, and the third universal wheel 3 to form a closed loop;

[0030] The driving mechanism is used to drive the first universal wheel 1 and the third universal wheel 3 to move in the same direction, drive the wire saw rope 10 to perform cutting or resetting, and at the same time is used to drive the fourth universal wheel 4 to move in the opposite direction to the third universal wheel 3.

[0031] An embodiment of the present invention provides a wire saw rope cutting system. Within the framework range of the gantry, by arranging a laterally movable first universal wheel on the upper cross beam frame, and arranging a laterally movable third universal wheel and a fourth universal wheel on the lower cross beam frame, and fixedly arranging a second universal wheel and a fifth universal wheel on the first longitudinal beam frame; the wire saw rope is sequentially wound around the first universal wheel, the second universal wheel, the wire saw machine, the fourth universal wheel, the fifth universal wheel and the third universal wheel to form a closed loop. The contour range formed by the first universal wheel, the second universal wheel, the third universal wheel and the fifth universal wheel can accommodate large parts. The driving mechanism drives the first universal wheel and the third universal wheel to move in the same direction, realizing the cutting of large parts and the wire saw rope returning to the initial cutting position after cutting is completed, waiting for the next feeding, and cutting in this cycle. The wire saw machine cutting system provided by the embodiment of the present invention can realize the cutting of large parts by using a gantry, and at the same time can realize the automatic cutting of the wire saw rope and the automatic return of the wire saw rope to the initial cutting position after cutting by using a driving mechanism, without manually repeatedly adjusting the position of the wire saw rope, saving time and effort and having high working efficiency.

[0032] Combined with the embodiments of the present invention, the overall structure of a wire saw machine cutting system provided by the embodiments of the present invention will be described next.

[0033] Combined with the embodiments of the present invention, see Figure 3 and Figure 4 , for the description of the structure of the gantry 9. The gantry 9 is a frame structure, and large parts can be accommodated within the frame of the gantry 9. For example, when cutting a wind turbine blade, the wind turbine blade can be horizontally transported into the "mouth"-shaped frame of the gantry 9. The gantry 9 includes an upper cross beam frame 91, a lower cross beam frame 92, a first longitudinal beam frame 94, a second longitudinal beam frame 93 that form a frame structure, and hydraulic cylinders 95 on both sides. A guide rail 11 is provided on the upper middle cross beam 911 of the upper cross beam frame 91. The lower middle cross beam 921 of the lower cross beam frame 92 is directly below the upper middle cross beam 911. One side of the lower middle cross beam 921 is offset by a certain distance to be the lower side cross beam 922. Guide rails (not shown in the figure) are provided on both the lower middle cross beam 921 and the lower side cross beam 922. The first longitudinal beam frame 94 and the second longitudinal beam frame 93 are respectively on both sides of the gantry.

[0034] In combination with the embodiments of the present invention, the driving mechanism will be described. The driving mechanism includes: a first driving motor 8 and a second driving motor 7; the first driving motor 8 is connected to the first universal wheel 1 and is used to drive the first universal wheel 1 to move; the second driving motor 7 is used to drive the third universal wheel 3 and the first universal wheel 1 to move in the same direction, and is used to drive the fourth universal wheel 4 and the third universal wheel 3 to move in opposite directions.

[0035] In combination with the embodiments of the present invention, refer to Figure 1 and Figure 2 , the overall structure of the wire sawing machine cutting system will be described. A first universal wheel 1 that can move horizontally is arranged on the upper middle cross beam 911 of the gantry 9, and a second universal wheel 2 is arranged at the connection position between the upper middle cross beam 911 and the first longitudinal beam frame 94; the first universal wheel 1 is connected to the first driving motor 8, and the first driving motor 8 can drive the first universal wheel 1 to move horizontally on the upper middle cross beam 911 through a guide rail slider mechanism. Specifically, taking the illustration as an example, when the first driving motor 8 drives the first universal wheel 1 to move to the right along the guide rail 11 of the upper middle cross beam 911, the wire saw rope 10 can cut to the right; when the first driving motor 8 drives the first universal wheel 1 to move to the left along the guide rail 11 of the upper middle cross beam 911, the wire saw rope 10 can return to the cutting initial position to the left without manual adjustment. Optionally, the first driving motor 8 is a synchronous servo motor.

[0036] A third universal wheel 3 that can move horizontally is arranged on the lower middle cross beam 921 of the gantry 9, a fifth universal wheel 5 is arranged at the connection position between the lower middle cross beam 921 and the first longitudinal beam frame 94, and a fourth universal wheel 4 that can move horizontally is arranged on the lower side cross beam 922. The third universal wheel 3 moves horizontally along the lower middle cross beam 921 through a guide rail slider mechanism (the guide rail slider mechanism is not shown in the figure), and the fourth universal wheel 4 moves horizontally along the lower side cross beam 922 through a guide rail slider mechanism (the guide rail slider mechanism is not shown in the figure).

[0037] In combination with the embodiments of the present invention, refer to Figure 1 , the wire sawing machine 6 is located outside the first longitudinal beam frame 94 and away from the second longitudinal beam frame 93. It can be understood that the longitudinal beam frame where the fixed second universal wheel 2 and fifth universal wheel 5 are located is the first longitudinal beam frame 94. In a specific embodiment, as Figure 1 shown, the first longitudinal beam frame 94 is the right longitudinal beam frame, the second longitudinal beam frame 93 is the left longitudinal beam frame, and the wire sawing machine 6 is located outside the right longitudinal beam frame.

[0038] In combination with the embodiments of the present invention, refer to Figure 5, the wire saw rope 10 is successively wound around the first universal wheel 1, the second universal wheel 2, the wire saw machine 6, the fourth universal wheel 4, the fifth universal wheel 5 and the third universal wheel 3 to form a closed loop. Among them, the position of the fourth universal wheel 4 on the lower cross beam frame is lower than that of the third universal wheel 3. As can be seen from the figure, the laterally movable fourth universal wheel 4 and the third universal wheel 3 form a movable pulley group.

[0039] The second drive motor 7 is fixedly arranged at the connection of the lower cross beam frame 92 and the second longitudinal beam frame 93, and is located between the lower middle cross beam 921 and the lower side cross beam 922. The second drive motor 7 is connected to a synchronous pulley mechanism (not shown in the figure). The synchronous pulley mechanism includes a synchronous pulley and a synchronous belt. The second drive motor 7 drives the synchronous pulley, and the synchronous pulley drives the synchronous belt to move. One side of the synchronous belt is cooperatively connected with the third universal wheel 3, and the other side of the synchronous belt is cooperatively connected with the fourth universal wheel 4. When the second drive motor 7 drives the synchronous pulley mechanism to work, the synchronous belt drives the third universal wheel 3 and the fourth universal wheel 4 to move in opposite directions respectively. Specifically, taking Figure 1 and Figure 5 as examples for illustration, when the second drive motor 7 drives the third universal wheel 3 to move to the right along the guide rail of the lower middle cross beam 921 through the synchronous pulley mechanism, the synchronous pulley mechanism simultaneously drives the fourth universal wheel 4 to move to the left along the guide rail of the lower side cross beam 922, and the wire saw rope 10 can cut to the right. Since the fourth universal wheel 4 is the movable wheel part of the movable pulley group, according to the characteristics of the movable pulley, the distance that the fourth universal wheel 4 moves to the left is one-half of the moving distance of the wire saw rope 10; when the second drive motor 7 drives the third universal wheel 3 to move to the left along the guide rail of the lower middle cross beam 921 through the synchronous pulley mechanism, the synchronous pulley mechanism simultaneously drives the fourth universal wheel 4 to move to the right along the guide rail of the lower side cross beam 922, and the wire saw rope 10 can return to the cutting initial position to the left without manual adjustment. Optionally, the second drive motor 7 is a synchronous servo motor.

[0040] Combined with the embodiments of the present invention, a wire saw machine cutting system provided by the embodiments of the present invention further includes a start switch and a reset switch. The start switch is used to control the first drive motor 8 to drive the first universal wheel 1 and the second drive motor 7 to drive the third universal wheel 3 to move in the same direction for cutting when the wire saw rope 10 is in the cutting initial position; when the wire saw machine cutting system completes cutting, the reset switch is used to control the first drive motor 8 to drive the first universal wheel 3 to return to the cutting initial position, and is used to control the second drive motor 7 to drive the third universal wheel 3 and the fourth universal wheel 4 to return to the cutting initial position. At this time, the wire saw rope 10 is also in the cutting initial position accordingly.

[0041] Next, combined with Figure 1 and Figure 5 , the working process of a wire saw machine cutting system provided by the embodiments of the present invention will be described in detail.

[0042] First, within the framework of the gantry 9, the first universal wheel 3 and the third universal wheel 3 are respectively located near the second longitudinal beam 93. At this time, the cuttable space of the wire saw rope 10 within the gantry 9 is determined by the "mouth"-shaped space formed by the first universal wheel 1, the second universal wheel 2, the third universal wheel 3, and the fifth universal wheel 5. When the first universal wheel 1 and the third universal wheel 3 move synchronously towards the first longitudinal beam 94, the cuttable space becomes smaller; when the first universal wheel 1 and the third universal wheel 3 move synchronously towards the second longitudinal beam 93, the cuttable space becomes larger.

[0043] When the wire saw rope 10 is in the initial cutting position, the wind turbine blade is conveyed into the cutting space of the wire saw rope 10.

[0044] Subsequently, the wire saw machine 6 is started to drive the wire saw rope 10 to rotate together; the first drive motor 8 drives the first universal wheel 1 to move to the right, and at the same time, the second drive motor 7 drives the synchronous pulley mechanism to drive the third universal wheel 3 to move to the right and the fourth universal wheel 4 to move to the left. At this time, the wire saw rope 10 moves to the right to cut the wind turbine blade until the cutting is completed.

[0045] Finally, the first drive motor 8 drives the first universal wheel 1 to move to the left, and at the same time, the second drive motor 7 drives the synchronous pulley mechanism to drive the third universal wheel 3 to move to the left and the fourth universal wheel 4 to move to the right. At this time, the wire saw rope 10 moves back to the left to the initial cutting position. Throughout the process, the wire saw rope 10 is always buckled on the universal wheels and will not fall off. After waiting for the first universal wheel 1, the third universal wheel 3, and the fourth universal wheel 4 to return to the initial positions, just wait for the next feeding action to be in place.

[0046] The above is a complete working state of the wire saw machine cutting system. By following this, cyclic cutting is achieved, enabling the cutting of large parts without the need for manual repeated adjustment of the position of the wire saw rope, saving time and effort and having high work efficiency.
