Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade recycling technology, and in particular to a mobile large-scale waste wind turbine blade on-site cutting and processing equipment. Background Technology

[0002] Currently, retired wind turbine blades and those damaged during use are weighing nearly 10 tons each, are enormous, approximately 38 meters long, and have a maximum width exceeding 3 meters. Therefore, transporting retired blades entirely to recycling plants for cutting and processing is extremely difficult and costly. With increased domestic investment in offshore wind power, wind turbine blade sizes are expected to further increase in the future to capture more wind power. Given this trend of increasing overall blade size, transporting retired blades entirely as a unit would increase transportation costs and difficulties, making the issue of whole-blade transportation and recycling even more prominent. Therefore, when recycling fiberglass wind turbine blades, the first step is to cut large wind turbine blades on-site. Currently, direct cutting of blades in wind farms is often done manually or with a wire saw. Manual cutting is difficult, dangerous, unsafe, and inefficient. Wire saw cutting requires specialized equipment to lift the blade before the tooling can be fixed on it for cutting, making the operation cumbersome and complex. Some methods use mobile cutting machinery and hoisting equipment to cut the blades. However, due to the large size of the blades, regardless of the cutting method used, the hoisting device needs to constantly adjust the blade position during the cutting process to obtain the appropriate cutting position and angle. This results in low cutting efficiency, long operation cycles, poor on-site working environment, and low safety. Utility Model Content

[0049] Currently, the direct recycling and cutting of large wind turbine blades in wind farms is often done manually or with wire saws. Manual cutting is difficult, dangerous, unsafe, and slow. Wire sawing requires specialized equipment to lift the blade before the tooling can be fixed on it for cutting, making the operation cumbersome and complex. Some methods use mobile cutting machinery and hoisting equipment to cut the blades; however, due to the large size of the blades, regardless of the cutting method used, the hoisting device needs to constantly adjust the blade position during the cutting process to obtain the appropriate cutting position and angle. Furthermore, the hoisting device is prone to swaying, resulting in low cutting efficiency, long operation cycles, poor on-site working environment, and low safety.

[0050] In view of this, such as Figures 1 to 5 As shown, this solution provides a mobile, large-scale on-site cutting and processing equipment for waste wind turbine blades to alleviate the above-mentioned problems.

[0051] This equipment includes a gripping device 100 and a cutting device 200;

[0052] The gripping equipment 100 is equipped with a hydraulic clamping device 110;

[0053] While the cutting equipment 200 cuts the blades using the hydraulic circular saw 210, the hydraulic clamping device 110 can clamp the blades, and the hydraulic clamping device 110 can adjust the angle of the gripper 111 according to the position of the blade to be clamped.

[0054] Specifically, the gripping equipment 100 is used to assist the cutting equipment 200 in fixing the wind turbine blades during blade cutting operations, and to grip and load the cut sheet-like blade material onto a vehicle. The rotatable and adjustable gripper 111 can use blades at different angles and orientations, thereby fixing the cut part when the cutting equipment 200 cuts the blade at different positions, and preventing the blade from shaking under force and affecting the cutting effect.

[0055] In this scheme, the hydraulic clamping device 110 includes a gripper 111, a main body 112, and a first hydraulic motor 113;

[0056] Two grippers 111 are hinged to the main body 112 respectively, and the tips of the two grippers 111 are respectively set to face each other;

[0057] A hydraulic cylinder is installed inside the main body 112;

[0058] The output end of the hydraulic cylinder is fixedly connected to the gripper 111;

[0059] The hydraulic cylinder can drive the two grippers 111 to move closer to each other or further apart;

[0060] The side of the main body 112 away from the gripper 111 is connected to the output end of the first hydraulic motor 113;

[0061] The first hydraulic motor 113 can drive the main body 112 to rotate;

[0062] The grabbing equipment 100 also includes a first tracked vehicle body 120;

[0063] The first tracked vehicle body 120 is connected to the hydraulic clamping device 110 via the first robotic arm 130;

[0064] The first tracked vehicle body 120 can drive the first robotic arm 130 to rotate.

[0065] Specifically, the upper part of the hydraulic clamping device 110 is fixedly connected to the first robotic arm 130 via a connecting seat. The seat body is made of high-strength steel plate and is designed with upper and lower flanges, which are respectively connected to the upper seat lug and the lower first hydraulic motor 113 using high-strength bolts. There are two connecting holes on the seat lug, through which high-strength pins can be passed to connect to the boom and forearm on the robotic arm of the mobile device. The connecting seat is made of high-strength thick plate and is equipped with reinforcing ribs. The lower part is designed with a thick flange and is connected to the rotating device via high-strength bolts. The adjusting sleeve is designed with multiple sets of thicknesses for installation on the pins, which can eliminate the axial gap between the seat lug and the boom and forearm after installation, and improve the dimensional adaptability and flexibility of the hydraulic clamping device and the robotic arm installation.

[0066] The opening and closing of the gripper 111 is controlled by a hydraulic cylinder. The hydraulic cylinder is located inside the main body 112. The two ends of the hydraulic cylinder 111 are respectively provided with a cylinder head hinge and a cylinder seat hinge. The cylinder head hinge and the cylinder seat hinge are rotatably connected to the inside of the main body 112 through a rotating shaft. The cylinder head hinge and the cylinder seat hinge are each hinged to a gripper. The cylinder head hinge and the cylinder seat hinge are connected by a connecting rod. When the hydraulic cylinder extends, the gripper 111 is in a closed state. When the hydraulic cylinder retracts, the gripper 111 is in an open state.

[0067] The maximum opening size of the gripper 111 is 1400mm, the closing working pressure of the hydraulic cylinder is 18-20MPa, and the closing working flow rate is 45-50L / min. The hydraulic cylinder transmits force to the gripper 111 through a hinge and connecting rod structure, which can generate a gripping force of over 500kg.

[0068] The main body 112 is also equipped with a special solenoid valve for adjusting and switching the oil supply for the rotation of the main body 112 and the opening and closing of the gripper 111, so as to realize the function of the gripper 111 rotating and opening and closing.

[0069] In this design, the cutting equipment 200 includes a second tracked vehicle body 220;

[0070] The second tracked vehicle body 220 is connected to the hydraulic circular saw 210 via the second robotic arm 230.

[0071] The second tracked vehicle body 220 can drive the second robotic arm 230 to rotate;

[0072] The hydraulic circular saw 210 includes a saw blade motor 221, a saw blade 222, and a protective cover 223;

[0073] The saw blade motor 221 is splined to the connecting rod of the saw blade 222;

[0074] The protective cover 223 is fitted onto the upper part of the saw blade 222;

[0075] The cutting equipment 200 also includes a second hydraulic motor 240;

[0076] The upper part of the second hydraulic motor 240 is fixedly connected to the second robotic arm 230 via a connecting seat;

[0077] The output end of the second hydraulic motor 240 is connected to the gear housing outside the saw blade motor 221;

[0078] The second hydraulic motor 240 can drive the saw blade motor 221 to rotate.

[0079] Specifically, the saw blade motor 221 is installed inside the housing. The motor is a low-speed, high-torque hydraulic motor with a speed range of 300~600 r / min, a working pressure of 25 MPa, an oil supply flow of 200~400 L / min, and a rated power of 59 kW.

[0080] The saw blade 222 consists of a base and cutting teeth. The base is made of 65Mn alloy steel with a thickness of 7.5-9mm. The cutting teeth are made of diamond and have a cutter head structure with broken teeth. The cutting teeth are 9-12mm thick. The thickness of the cutting teeth is greater than that of the base, which can reduce the phenomenon of blade jamming when cutting materials.

[0081] The diameter of the saw blade 222 is 1200~1800mm, corresponding to an effective cutting depth of 300~600mm and a cutting speed of 300~500r / min, to ensure that the rotating disc can generate sufficient shearing force and ensure the cutting efficiency of wind turbine blades.

[0082] The second hydraulic motor 240 adopts a worm gear hydraulic rotary reducer structure. The upper part of the reducer is fixedly connected to the connecting seat by bolts, and the lower rotating part is connected to the saw blade motor housing. The 360° rotation angle of the saw blade can be adjusted by hydraulic oil supply. The working pressure of the second hydraulic motor 240 is 12-14MPa, and the working flow rate is 30-70L / min.

[0083] The first tracked vehicle body 120 and the second tracked vehicle body 220 have the same structure. The tracks are made of rolled track plates. A turntable is set on the upper part of the tracks. The turntable is equipped with a driver's cab, a hydraulic transmission device, an oil supply device and a slewing device. The hydraulic circular saw 210 is equipped with a solenoid valve group. The hydraulic transmission device uses a single set of oil supply pipelines. Under the control of the solenoid valve group, the hydraulic oil is distributed to the saw blade motor 221 and the second hydraulic motor 240. The maximum oil supply flow rate of the oil supply device is 400L / min and the maximum oil supply pressure is 37MPa.

[0084] Preferably, the protective cover 223 is made of steel plate with a thickness of not less than 5mm and adopts a reinforcing rib structure to prevent the saw blade 222 from falling off and splashing and injuring people during operation. In addition, the outer wall of the protective cover 223 is provided with a water supply pipe connected to the water spray nozzle. The water spray nozzle is located at both ends of the protective cover 223. When the saw blade 222 cuts the blade, the water spray nozzle can spray water from different angles to the cutting area to reduce the operating temperature and suppress dust.

[0085] In this solution, the saw blade motor 221 is equipped with a visual blind spot monitoring system, which can be a distance sensor and a high-definition camera. The distance sensor is installed at the lower end of the housing of the saw blade motor 221, and the detection direction is along the diameter direction of the saw blade 222. It can display the real-time distance to the cutting surface when the saw blade 222 is cutting in the cab via an instrument, and set an alarm value for the extreme cutting depth to remind the operator. The high-definition camera is installed on the side of the saw blade motor 221 directly opposite the blade, and can display the image of the cutting operation in the cab, enhancing the operator's real-time control of the cutting position and cutting conditions.

[0086] A mobile large-scale waste wind turbine blade on-site cutting and processing system can be implemented using the aforementioned mobile large-scale waste wind turbine blade on-site cutting and processing equipment.

[0087] In this solution, the cutting process of the mobile large-scale waste wind turbine blade on-site cutting and processing equipment is as follows:

[0088] S1: Blade front section cutting: When the blade front section height is <400mm, the blade is directly radially cut off;

[0089] S2: When the section height of the blade's middle segment is greater than 400mm, first, make a horizontal cut at the junction of the upper and lower surfaces of the leading edge, with a cutting length of approximately 3-4m; then, sequentially make axial vertical cuts at the junction of the leading edge and the main beam, the junction of the upper and lower surfaces of the trailing edge, and the junction of the trailing edge and the main beam; then, make radial vertical cuts to remove the upper skin of the leading edge, exposing the internal web of the blade; continue radial vertical cuts to radially cut open the lower part of the leading edge skin; then, adjust the cutter to make a horizontal cut on the side web of the leading edge; then, make a radial longitudinal cut to remove the upper skin of the trailing edge, exposing the side web of the trailing edge, and adjust the cutter to make a horizontal cut on the side web of the trailing edge; then, adjust the cutter to radially vertically cut away the upper part of the main beam, and continue radial vertical cuts to radially cut open the lower part of the leading edge skin; then, sequentially make axial vertical cuts at the junction of the trailing edge and the main beam, and the junction of the leading edge and the main beam; finally, cut away the lower part of the main beam. Each segment requires 14 cuts, including 3 horizontal cuts, 6 axial longitudinal cuts, and 4 radial longitudinal cuts. During the cutting process, a gripping device can be used to straighten and clamp the cut and separated materials.

[0090] S3: Cut at the leaf root, cut into 4 pieces along the axial direction (blocks with a height < 400mm); each section is cut 8 times, from top to bottom, 4 times axially and 4 times radially.

[0091] This solution has at least the following beneficial effects:

[0092] This solution provides a mobile, large-scale on-site cutting and processing equipment for waste wind turbine blades, effectively solving the problems of high operational difficulty, low safety, low efficiency, and poor working environment associated with traditional manual or wire saw cutting methods. This equipment achieves efficient and stable cutting of wind turbine blades through the coordinated use of a gripping and cutting device. The gripping device is equipped with an adjustable-angle hydraulic clamping device, which can flexibly hold blades at different angles and positions, and fix the blades during cutting to prevent swaying, thus improving cutting accuracy and safety. The cutting device uses a high-performance hydraulic circular saw with high torque, high speed, and deep cutting capabilities. Combined with a protective cover and water spray system, it ensures efficient and safe cutting while reducing dust and temperature. Furthermore, the equipment is equipped with a blind-spot monitoring system, enhancing the operator's real-time control of the cutting process. The overall structure adopts a tracked vehicle body and robotic arm linkage design, improving the equipment's mobility and adaptability, making it suitable for rapid operation in complex wind farm environments, and significantly improving cutting efficiency, operational safety, and environmental performance.
