[0052] With the development of large-megawatt offshore units, medium-speed permanent magnet technology has gradually become the mainstream. Currently, the units developed are at the 18MW level, and the blade length exceeds 120 meters. Therefore, blade installation has become a technical bottleneck restricting the development of large-megawatt units. Due to manufacturing and control logic reasons, the currently developed medium-speed permanent magnet unit turning tooling can easily cause uncontrollable rotation when the impeller is turned during the blade installation process, which poses a great safety risk to construction and installation. For example, when the internal transmission parts of the turning tooling slip or loosen, no-load operation will occur, and the brake disc will rotate too fast and the turning will fail. For example, if the blades are too heavy or the internal transmission parts of the turning tooling are stuck, the brake disc may rotate too slowly, and the motor may be driven at full power, which is easy to cause a fault. However, the current turning tooling cannot detect the turning failure in time, nor can it be effectively locked, which increases safety hazards.

[0053] Specifically, there are two common types of winch tooling on the market, one is electric drive and the other is hydraulic drive. The electric drive winch tooling has a low cost, but it cannot achieve mechanical locking and has poor safety. In the actual lifting process, once the winch rotation fails, there is currently no other safe and controllable way except the braking of the motor itself. Especially in the case of large torque, the braking reliability is not very high, the risk is high, and it is easy to continue to rotate under the influence of the load after braking. The hydraulically driven winch tooling has a complex control structure and high cost, and once there is a problem with the hydraulic system, it is also easy to fail. Therefore, how to achieve the winch tooling without stalling and losing control after loading has always been a technical bottleneck in the industry. Common methods include driving through a hydraulic motor, controlling the pressure through a balance valve and a one-way valve, and achieving locking with load, but once there are problems such as oil leakage from the oil pipe joint and joint leakage, the hydraulic part is also prone to failure. Therefore, it is urgent to design a winch tooling and a control method that can monitor and control the rotation state of the loaded winch in real time, so that the winch with load is safe and controllable.

[0054] Based on this, an embodiment of the present invention proposes a cranking tool. The cranking tool can be applied to a wind turbine generator set, for example, during the installation of the blades 90, the hub 80 is cranked, and the blade interface of the hub 80 is rotated to a horizontal position or other set position, so that the installer can connect the blades 90 and the hub 80 together. Specifically, the cranking device is connected to the rotor of the generator (not shown in the figure), and drives the rotor to rotate, thereby driving the hub 80 connected to the rotor to rotate. Of course, the cranking tool can also be applied to other components of the wind turbine generator set, or it may not be applied to the wind turbine generator set, but to other equipment that requires cranking. For the convenience of description below, a cranking tool is connected to the rotor of the generator of the wind turbine generator set, and the hub 80 is cranked as an example for detailed description, but it is not limited to this.

[0055] The turning tool includes a rotatable part. The rotatable part is used to connect with the component to be turned, such as the rotor of the generator, so as to drive the rotor to rotate, thereby driving the hub 80 linked with the rotor to rotate for turning, and facilitating the installation of the blades 90.

[0056] The turning tool further includes a brake disc 210, which can drive the rotatable part to rotate for turning.

[0057] Specifically, since the blade 90 is heavy, the turning tool is under a heavy load during loaded operation. To improve the rotation stability of the turning tool, the brake disc 210 can drive the rotatable part to rotate through gear transmission, which can bear a large torque and is conducive to stable turning.

[0058] As an example, Figure 1 , Figure 2 and Figure 3As shown, the turning tool further includes a first transmission gear 310 and a second transmission gear 320. The first transmission gear 310 is connected to the brake disc 210 and rotates synchronously with the brake disc 210. The first transmission gear 310 is meshed with the second transmission gear 320. The second transmission gear 320 is configured as a rotatable member.

[0059] Reference here Figure 1 , the number of brake discs 210 can be two, the number of first transmission gears 310 can be two, and the two first transmission gears 310 can mesh with the second transmission gear 320 at the same time, driving the second transmission gear 320 to rotate in two directions, and the rotation stability is good. At this time, reference Figure 3 The brake disc driving member 220 for driving the brake disc 210 to rotate may include two motors, namely a first driving motor 221 and a second driving motor 223. The first driving motor 221 is connected to one brake disc 210 via a first gear box 222, and the second driving motor 223 is connected to another brake disc 210 via a second gear box 224.

[0060] Of course, in other examples, the second transmission gear 320 and the rotatable member may be two independent components, which are connected together for synchronous rotation.

[0061] In addition, the turning tool further includes a brake disc driving component 220 for driving the brake disc 210 to rotate.

[0062] As an example, the brake disc driving member 220 includes a driving motor and a gear box, and the driving motor drives the brake disc 210 to rotate via the gear box.

[0063] Specifically, refer to Figure 3 When there are two brake discs 210, the brake disc driver 220 includes a first drive motor 221, a first gear box 222, a second drive motor 223, and a second gear box 224. The first drive motor 221 is connected to one of the brake discs 210 via the first gear box 222, and the second drive motor 223 is connected to the other brake disc 210 via the second gear box 224.

[0064] Furthermore, if Figure 6 and Figure 7 As shown, the brake disc 210 is provided with a plurality of circumferentially distributed plug holes 211. Figure 3 , Figure 4 and Figure 5As shown, the turning tool further includes a locking module, which includes a bracket 250, a locking pin 230 and a locking pin driving member (not shown in the figure), the locking pin 230 is movably arranged on the bracket 250, and the locking pin driving member is used to drive the locking pin 230 to extend into the insertion hole 211 on the brake disc 210. The brake disc 210 is restricted by the locking pin 230 and cannot continue to rotate.

[0065] The locking pin 230 is inserted into the socket 211 to limit the rotation of the brake disc 210. Compared with the related art that only relies on the motor to stop to prevent the brake disc 210 from rotating, and the large torque only relies on motor braking, it is beneficial to effectively stop the turning tool and stably maintain it in the stopped position. Compared with the related art that only relies on the hydraulic drive brake caliper 240 to control the brake disc 210 to stop, the problem of load stall caused by the risk of leakage can be avoided. The structure of the turning tool itself and the components to be turned can be protected to avoid continued rotation after a fault occurs and expand the impact of the fault. In addition, it is convenient for the crew to install, repair and other operations on the unit and the turning tool after the brake disc 210 stops stably, which can improve the safety of the unit installers.

[0066] Here, the locking bolt driver can be an electric driver, such as an electromagnetic push rod, etc., to avoid leakage of the hydraulic drive, and the reliability is high. Of course, the locking bolt driver can also be a hydraulic driver.

[0067] In addition, the locking pin driver and the brake disc driver 220 for driving the brake disc 210 to rotate can be independent of each other, independently drive the locking pin 230 and independently stop driving the brake disc 210 to rotate, so that multiple braking operations can be performed on the brake disc 210.

[0068] As for the specific structure of the insertion hole 211, the insertion hole 211 is further configured as a long strip hole extending along the circumference of the brake disc 210. On the one hand, the probability of the locking pin 230 being inserted into the insertion hole 211 is increased, and it is convenient for the locking pin 230 to lock the brake disc 210. On the other hand, after the locking pin 230 is inserted into one end of the insertion hole 211, as the brake disc 210 rotates, the locking pin 230 can move a certain distance in the insertion hole 211 and then abut against the inner wall of the insertion hole 211, which has a certain buffering effect compared with locking immediately after being inserted into the insertion hole 211.

[0069] Further, the space enclosed by one end of the plug hole 211 in the circumferential direction of the brake disc 210 is large, which is configured as a large head end 2111, and the space enclosed by the other end of the plug hole 211 in the circumferential direction of the brake disc 210 is small, which is configured as a small head end 2112. The locking pin 230 can shrink and expand radially. Therefore, when the brake disc 210 rotates from the direction of the small head end 2112 of a plug hole 211 to the direction of the large head end 2111, the locking pin 230 can be inserted into the plug hole 211 through the large head end 2111, and then squeezed and shrunk to abut against the small head end 2112. When the brake disc 210 rotates from the direction of the large head end 2111 of a plug hole 211 to the direction of the small head end 2112, the locking pin 230 can be inserted into the plug hole 211 and abut against the large head end 2111.

[0070] The locking pin 230 can shrink and expand radially, and after being inserted into the socket 211, it is gradually squeezed and shrunk by the small head end 2112 of the socket 211 as the brake disc 210 rotates. Compared with the rigid collision between the locking pin 230 and the socket 211, the impact force can be reduced, and the risk of the locking pin 230 breaking can be reduced, thereby ensuring that the locking pin 230 stably locks the brake disc 210. In addition, during the locking process, the locking ability can be gradually adjusted as the size of the brake disc 210 hole is adjusted, and a buffer zone is reserved, so that the locking pin 230 will not be too much impacted, ensuring the stability of the mechanical structure. It can solve the problem that the traditional pin is too small and unevenly stressed, resulting in the concentration of individual pins.

[0071] The current unit does not have a brake disc 210, so all braking needs to be borne by the main body of the turning tool. The turning tool is designed with a micro brake disc structure, which is used for gear transmission for turning, but the traditional brake disc cannot brake quickly. It mainly slows down the rotation speed by friction of the friction plate and cannot stop at a fixed point. The present embodiment is designed with a self-locking brake disc structure. Through the large and small head ends of the insertion hole 211 of the brake disc 210 and the adjustment of the locking pin 230, the brake disc 210 is used to slow down the rotation speed of the loaded turning car. At the same time, through the uniformly distributed specific brake disc 210 holes, the locking pin 230 is inserted from the large head end 2111, and the rotation of the brake disc 210 is used to squeeze the locking pin 230 to achieve buffered locking of the pin. At the same time, the hole of the brake disc 210 becomes smaller. After the buffer zone ends, it can be accurately positioned and locked to ensure the safe locking of the turning car with load.

[0072] As an example, Figure 6 and Figure 7As shown, the big end 2111 and the small end 2112 of the socket 211 are circular, connected by a smooth arc in the middle, similar to a water drop shape, which can realize a smooth transition from a large diameter to a small diameter of the locking pin 230. Of course, the big end 2111 and the small end 2112 can also be connected by two tangents in the middle, which is convenient for processing. The diameter of the circle corresponding to the small end 2112 can be the diameter of the locking pin 230 after being compressed, and the diameter of the circle corresponding to the big end 2111 can be the diameter of the locking pin 230 in the expanded state. It is convenient for the locking pin 230 to fully abut against the socket 211 and lock. Or the diameter of the locking pin 230 in the expanded state, that is, its diameter in the natural state is smaller than the diameter of the circle corresponding to the big end 2111, and larger than the diameter of the circle corresponding to the small end 2112, so that the locking pin 230 is smoothly inserted into the socket 211.

[0073] refer to Figure 6 , the distance M between the center of the large circle corresponding to the large end 2111 and the center of the small circle corresponding to the small end 2112, as well as the small circle pitch circle radius R1 and the large circle pitch circle radius R2 can be designed according to the gear ratio of the unit gearbox and the instantaneous impeller locking time allowed by the impeller end to meet the acceleration impact caused by the sudden impeller load stop of the unit. When the turning gear is running with load, M is the buffer area of ​​the locking pin 230. Therefore, the instantaneous locking of the brake disc 210 can set the pin buffer area according to the above parameters to ensure that the overall force of the locking pin 230 is uniform and safe and reliable. In addition, the number of holes 211 opened on the brake disc 210 can be designed according to the actual requirements of braking accuracy, which is generally greater than 3. The maximum number depends on the torque carried, that is, when there are many holes, the structure of the brake disc 210 itself can meet the load requirements. The hole form can be symmetrical, evenly distributed, or set according to the structure of the bracket 250. Therefore, in addition to the above-mentioned shapes, the structure of the hole 211 can also include other structures such as round, square, diamond, etc., which belong to the present design concept.

[0074] Furthermore, a plurality of sockets 211 are distributed in a plurality of circles around the rotation center line of the brake disc 210. In each circle of sockets 211, the large end 2111 of any socket 211 is close to the small end 2112 of the adjacent socket 211. The arrangement directions of the inner and outer circles of sockets 211 are opposite. For example, the large end 2111 of one circle of sockets 211 faces clockwise, and the large end 2111 of the other circle of sockets 211 faces counterclockwise. There are a plurality of locking pins 230, and each circle of sockets 211 is arranged opposite to at least one locking pin 230. This ensures that when the brake disc 210 rotates clockwise and counterclockwise, the locking pin 230 can buffer and lock the brake disc 210 without causing too much impact with the brake disc 210.

[0075] For example, the multiple jacks 211 are distributed in two circles, inner and outer, around the rotation center line of the brake disc 210. Figure 6 , the big end 2111 of each socket 211 of the inner circle is in the counterclockwise direction of its small end 2112, and the big end 2111 of each socket 211 of the outer circle is in the clockwise direction of its small end 2112. There are two locking pins 230, corresponding to the positions of the inner circle socket 211 and the outer circle socket 211 respectively. When the brake disc 210 rotates clockwise, the locking pin 230 corresponding to the outer circle is first inserted into the socket 211 through the big end 2111 of the outer circle socket 211, and then as the brake disc 210 rotates, it is squeezed and contracted by the inner wall of the socket 211 until it abuts against the socket 211, thereby locking the brake disc 210. Meanwhile, when the locking pin 230 corresponding to the inner ring plug hole 211 is first opposite to the small head end 2112, it will not extend into the plug hole 211. As the brake disc 210 rotates, the size of the plug hole 211 gradually increases. The locking pin 230 is inserted into the plug hole 211 and can abut against the large head end 2111 of the inner ring plug hole 211 when the outer ring locking pin 230 abuts against the outer ring plug hole 211. While achieving double locking of the inner and outer rings, the outer ring locking pin 230 can also buffer and lock the brake disc 210 to avoid a large impact.

[0076] Of course, the number of the locking pins 230 here can be four, six, etc. in addition to two, and each circle of the socket 211 corresponds to multiple locking pins 230, firmly locking the brake disc 210. Similarly, the sockets 211 can also be distributed in three circles, four circles, or even more circles, corresponding to more locking pins 230, firmly locking the brake disc 210. The structural design of the large and small ends of the socket 211 can squeeze all the locking pins 230 during the rotation process, so that all the locking pins 230 are more evenly stressed, ensuring that the torque transmission of the mechanical interface is safe and reliable.

[0077] Furthermore, if Figure 4 and Figure 5 As shown, the turning tool also includes a brake module, which is arranged outside the brake disc 210. The brake module includes a brake caliper 240 and a caliper driver, and the caliper driver can drive the brake caliper 240 to apply friction braking to the brake disc 210.

[0078] In addition to using the locking pin 230 to lock the brake disc 210, the brake caliper 240 can also be used to brake the brake disc 210. The two provide redundant protection. When a problem occurs with the turning tool and the turning needs to be stopped, two methods can be used to brake and two methods can be used to limit the rotation of the brake disc 210, thereby ensuring that the turning tool will not rotate accidentally, thereby improving the safety of the crew.

[0079] In a specific application, the clamp driver may be a hydraulic driver. The brake clamp 240 is disposed on the bracket 250, between the first baffle 251 and the second baffle 252, and on both sides of the brake disc 210, for clamping the brake disc 210. The clamp driver may be a motor driver.

[0080] Furthermore, the turning tool further includes a detection module, which is used to detect the rotation parameters of the rotatable part and / or the rotation parameters of the brake disc 210. The detection module can be used to timely understand the turning condition of the turning tool and timely find out whether the turning tool has a fault.

[0081] In a specific application, the rotation parameter may be the rotation speed, or may be other parameters that can reflect the size of the rotation speed.

[0082] The detection module may have only one detection device, and only detect the rotation parameters of the rotatable part, or only detect the rotation parameters of the brake disc 210, so as to reduce parts and save costs.

[0083] like Figure 3 and Figure 5 As shown, the detection module may also have two detection devices, namely a first detection device 50 and a second detection device 40. The first detection device 50 is used to detect the rotation parameters of the brake disc 210, and the second detection device 40 is used to detect the rotation parameters of the rotatable part. Monitoring the rotation of the turning tool at two positions can realize redundant monitoring of the turning condition and high-precision monitoring, which is conducive to timely detection of the turning problem after a turning failure occurs.

[0084] As an example, the first detection device 50 is a laser sensor, which is used to detect the time taken by the brake disc 210 to rotate to a set central angle. The bracket 250 is provided with a plurality of through holes, which are distributed around the center of the brake disc 210 at intervals of a set central angle, and the laser sensor is arranged relative to the positions of the plurality of through holes. By sensing the plurality of through holes, the time taken by the brake disc 210 to rotate to a set central angle is detected. The second detection device 40 is a rotary encoder, which is used to detect the rotation angle of the second transmission gear 320 within a set time.

[0085] Of course, the first detection device 50 and the second detection device 40 may also be other sensors to detect the rotation speed of the brake disc 210 and the like.

[0086] Furthermore, the turning tool also includes a control module, which can be independent of the wind turbine generator set or have the same structure as the control device of the wind turbine generator set.

[0087] In some embodiments, the control module is used to control the locking bolt driver according to the detection result of the detection module.

[0088] In some embodiments, the control module is further configured to control the brake disc driver 220 according to the detection result of the detection module.

[0089] In some embodiments, the control module is further used to control the clamp driving member according to the detection results of the detection module.

[0090] The control module here is a general term for the control structure, which does not mean that one control structure must control the three driving components. Multiple control structures can also control the locking pin driving component, the brake disc driving component 220 and the clamp driving component respectively. Multiple control structures can be set at different positions or assembled together.

[0091] Regarding the specific control method of the control module, in some embodiments, when the detection module can detect the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210, the control module can control one or more of the locking latch driver, the brake disc driver 220 and the clamp driver according to any of the rotation parameters of the rotatable part and the brake disc 210. When the detection module finds that there is a problem with the turning gear, braking or other adjustment methods can be performed in time.

[0092] As an example, when any of the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210 is lower than the corresponding set range, the control module sends a brake signal to the clamp driver to drive the brake clamp 240 to brake. At this time, the turning tool may rotate too slowly, and the brake disc 210 can be stopped by using the brake clamp 240 to brake, which is simple to operate. Before the brake clamp 240 is braked, the control module can also send a deceleration signal to the brake disc driver 220 to drive the brake disc 210 to rotate at a speed lower than the preset speed. Therefore, after the brake disc 210 decelerates and rotates, the brake clamp 240 is driven to brake, which is conducive to the rapid stop of the brake disc 210.

[0093] When the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210 are both within the corresponding set range, the control module controls the brake disc 210 to continue rotating. At this time, it means that there is no fault in the turning tooling, and the control module can send a full-speed signal to the brake disc driver 220 to drive the brake disc 210 to rotate at a preset speed and continue turning. Until the brake disc 210 rotates to the set angle, the brake disc 210 is controlled to stop rotating. Here, the brake disc driver 220 can be used to stop driving the brake disc 210 to rotate, and the brake caliper 240 can be controlled in conjunction with the clamp driver to brake the brake disc 210. After the brake disc 210 stops rotating, the locking pin driver can be controlled to drive the locking pin 230 to insert into the socket 211 of the brake disc 210 to lock the brake disc 210, thereby preventing the turning tooling from continuing to turn and rotate, affecting safety.

[0094] It should be noted that after the brake disc 210 stops rotating, when the turning tool is loaded, even if the brake caliper 240 clamps the brake disc 210, due to the heavy blade 90, when the blade 90 is not in a vertical state, the brake disc 210 will rotate a certain angle under the action of the torque brought by the load, thereby facilitating the locking pin 230 to be inserted into the socket 211.

[0095] When any one of the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210 is higher than the corresponding set range, the control module sends a brake signal to the clamp driver to drive the brake clamp 240 to brake, and sends a lock signal to the locking pin driver to drive the locking pin 230 to insert into the socket 211 during the deceleration of the brake disc 210. At this time, the turning tool may have the problem of too fast speed, which poses a great safety hazard. Therefore, the brake clamp 240 is emergency braked, and the locking pin 230 is inserted into the brake disc 210 during the deceleration of the brake disc 210, so that the brake disc 210 can be stopped quickly and stably, reducing the safety hazard. Here, the locking pin 230 is extended during the deceleration of the brake disc 210, which increases the probability of the locking pin 230 inserting into the socket 211 on the one hand, and reduces the wear of the locking pin 230 and the brake disc 210 on the other hand, and avoids the locking pin 230 from being inserted into the high-speed rotation of the brake disc 210 and generating a great impact with the brake disc 210.

[0096] In addition, in this case, the control module can also send a stop signal to the brake disc driver 220 to stop driving the brake disc 210 to rotate, and cooperate with the brake caliper 240 and the locking pin 230 to ensure that the brake disc 210 stops rotating in time.

[0097] Regarding the specific control method of the control module, in other embodiments, when the detection module is capable of detecting the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210, the control module can control one or more of the locking pin driver, the brake disc driver 220 and the clamp driver according to the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210.

[0098] As an example, when the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210 are both within the corresponding set range, the control module controls the brake disc 210 to continue rotating. At this time, it means that there is no fault in the turning tooling, and the control module can send a full-speed signal to the brake disc driver 220 to drive the brake disc 210 to rotate at a preset speed and continue turning. Until the brake disc 210 rotates to the set angle, the brake disc 210 is controlled to stop rotating. Here, the brake disc driver 220 can be used to stop driving the brake disc 210 to rotate, and the brake caliper 240 can also be controlled in conjunction with the clamp driver to brake the brake disc 210. After the brake disc 210 stops rotating, the locking pin driver can be controlled to drive the locking pin 230 to insert into the socket 211 of the brake disc 210 to lock the brake disc 210, thereby preventing the turning tooling from continuing to turn and rotate, affecting safety.

[0099] When one of the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210 is not within the corresponding setting range, the control module sends a brake signal to the clamp driver to drive the brake clamp 240 to brake. Since one of the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210 is not within the corresponding setting range, and the other is within the corresponding setting range, it means that the turning tooling has a fault, but the impact caused by the fault is not large at present. Therefore, in this case, the brake clamp 240 can be used to stop the brake disc 210, which is simple to operate. Of course, before the brake clamp 240 is braked, the control module can also send a deceleration signal to the brake disc driver 220 to drive the brake disc 210 to rotate at a speed lower than the preset speed, so that when the brake disc 210 is decelerated, the brake clamp 240 is driven to brake, which is conducive to the rapid stop of the brake disc 210 and reduces wear.

[0100] When the rotation parameters of the rotatable part and the rotation parameters of the brake disc 210 are not within the corresponding set range, the control module sends a brake signal to the clamp driver to drive the brake clamp 240 to brake, and sends a locking signal to the locking pin driver to drive the locking pin 230 to insert into the socket 211 during the deceleration of the brake disc 210. In this case, it means that the turning tooling has a fault and continuously affects the rotation parameters of the two positions. Therefore, emergency braking is required to avoid major problems. Therefore, the brake clamp 240 is emergency braked, and the locking pin 230 is inserted into the brake disc 210 during the deceleration of the brake disc 210, so that the brake disc 210 can be stopped quickly and stably, reducing safety hazards. Here, the locking pin 230 is extended during the deceleration of the brake disc 210, which increases the probability of the locking pin 230 inserting into the socket 211 on the one hand, and can reduce the wear of the locking pin 230 and the brake disc 210 on the other hand, and avoids the locking pin 230 from being inserted during the high-speed rotation of the brake disc 210, which has a greater impact on the brake disc 210.

[0101] In addition, in this case, the control module can also send a stop signal to the brake disc driver 220 to stop driving the brake disc 210 to rotate, and cooperate with the brake caliper 240 and the locking pin 230 to ensure that the brake disc 210 stops rotating in time.

[0102] Of course, in other embodiments, when the detection module can only detect the rotation parameters of the rotatable part or the rotation parameters of the brake disc 210, the control module can also control one or more of the locking pin driver, the brake disc driver 220 and the clamp driver according to the detected parameters.

[0103] In addition, referring to the above embodiment, the control module can control the brake disc 210 to continue rotating when the rotation parameter detected by the detection module is within the set range. The control module can also control the brake caliper 240 to engage the brake when the rotation parameter detected by the detection module is not within the set range, and control the locking pin 230 to insert into the socket 211 of the brake disc 210 during the deceleration process of the brake disc 210. Or the control module can also control the brake caliper 240 to engage the brake when the rotation parameter detected by the detection module is lower than the set range, and control the brake caliper 240 to engage the brake when the rotation parameter detected by the detection module is higher than the set range, and control the locking pin 230 to insert into the socket 211 of the brake disc 210 during the deceleration process of the brake disc 210.

[0104] To facilitate the connection between the rotatable member and the rotor, further, as Figure 1 , Figure 2 , Figure 3 and Fig.12 As shown, a plurality of connecting pins 110 are provided on one side of the rotatable member, and the plurality of connecting pins 110 are used for plugging and connecting with the waiting turning gear assembly, for example, plugging and connecting with the rotor. The structure is simple, the installation is convenient, and the rotatable member is convenient to drive the rotor to rotate synchronously.

[0105] The current rotor plug hole and the installation gap between the pins have a large deviation, and the design and manufacturing precision cannot be synchronized, resulting in a large gap, uneven force on the pins, and a small gap, which makes it impossible to install all the pins in multiple plug holes. In addition, the multiple pins of the current turning tooling cannot be stressed at the same time after installation, and there is an eccentricity problem, which causes individual pins to be stressed and easy to break. In order to reduce costs, most current wind turbine manufacturers have cancelled the brake disc structure of the original unit. Once the pin connected to the generator breaks, the impeller will rotate uncontrollably.

[0106] Therefore, in order to improve the connection stability of the connecting pin 110, it is further designed that the multiple connecting pins 110 can shrink and expand in the radial direction. The multiple connecting pins 110 are inserted into the plug holes of the rotor under pressure, so that the multiple connecting pins 110 can be stressed more evenly, and it is not easy for a single connecting pin 110 to break, thereby avoiding safety problems caused by the breakage of the pins.

[0107] Specifically, a plurality of connecting pins 110 are circumferentially spaced around the rotation centerline of the rotatable part. The plurality of connecting pins 110 are inserted into the plug holes of the rotor under pressure. In the process of hoisting the blades 90, when one or two blades 90 have been hoisted and the turning tool is rotating with load, under the influence of load and torque, if the connecting pin 110 is a simple metal shaft with an assembly gap between the connecting pin and the plug hole, it is possible that the connecting pin 110 at the top is almost not subjected to force, while the connecting pin 110 at the bottom is subjected to the greatest force. In this embodiment, the plurality of connecting pins 110 are able to contract and expand radially, so that the connecting pins 110 located at various locations can effectively support the rotor, so that the overall force of the plurality of connecting pins 110 is more balanced to avoid breakage.

[0108] Regarding the specific structure of the connecting pin 110, in some embodiments, as Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, each connecting pin 110 includes a second inner shaft 111, a plurality of second outer shaft pieces 112, and a second elastic component. The plurality of second outer shaft pieces 112 are circumferentially distributed on the outer side of the second inner shaft 111 to surround the second inner shaft 111. The second elastic component connects the second inner shaft 111 and the plurality of second outer shaft pieces 112, and the plurality of second outer shaft pieces 112 can be compressed and contracted to abut against each other in the circumferential direction of the second inner shaft 111 and press the second elastic component inwardly, and the plurality of second outer shaft pieces 112 can also expand outward and separate from each other under the elastic force of the second elastic component.

[0109] This structure with a second inner shaft 111 inside and multiple second outer shaft pieces 112 that can shrink and expand outside can ensure that the connecting pin 110 has a certain structural strength and can achieve expansion and shrinkage, which is convenient for stably supporting the rotor. In addition, since the outer peripheral part is designed as a split body, the production cost is low and can be made of waste scraps to reduce costs. The number of multiple second outer shaft pieces 112 is at least two, including but not limited to three, four, etc.

[0110] Fig.13 A schematic diagram of the side view of the connecting pin 110 is shown. Fig.14 , Fig.15 and Fig.16 They are Fig.13The figure is a cross-sectional view taken along the QQ direction, and is a cross-sectional view of the connecting pin 110 in different states.

[0111] Fig.14 A cross-sectional view of the connecting pin 110 in a natural state without being squeezed is shown. It can be seen that when the connecting pin 110 is not squeezed, the cross-section is substantially a perfect circle. Fig.15 The schematic diagram shows the connecting pin 110 in the process of being compressed. At this time, the second elastic component is compressed, and two adjacent second outer shaft sheets 112 have not yet completely abutted against each other. Fig.16 The cross-sectional schematic diagram of the connecting pin 110 in a compressed state is shown. At this time, any two circumferentially adjacent second outer shaft sheets 112 abut against each other, and the connecting pin 110 is compressed to a minimum state.

[0112] Here, the plurality of second outer shaft pieces 112 can be designed according to the maximum diameter, that is, when the connecting pin 110 is observed along the axial direction of the connecting pin 110, the connecting line of the outer contours of the plurality of second outer shaft pieces 112 in the natural state without compression is a circle. Therefore, after the second outer shaft pieces 112 are squeezed and contracted, the connecting line of the outer contours of the plurality of second outer shaft pieces 112 is non-circular and has a certain bulge, as shown in FIG. Fig.16 The connecting pin 110 has four bulges on the top, bottom, left and right sides, with the center position in the figure as the reference, which is similar to a square-circular structure. This structure can ensure buffering after a large deviation of the shaft-hole clearance. Even if the connecting pin 110 rotates, it will get stuck due to the non-circular structure after rotating to a certain angle, thereby ensuring that the connecting pin 110 can stably withstand torque. Fig.14 and Fig.16 As shown, L5 is the lateral movement space of the second outer shaft piece 112, L6 is the minimum diameter of the second outer shaft piece 112 in a compressed state, L7 is the buffer area of ​​the second outer shaft piece 112, and L8 is the difference between the maximum adaptation diameter and the minimum adaptation diameter of the connecting pin 110. Therefore, in order to adapt to the plug holes on different generator rotors, the size of the buffer area can be set according to the above four parameters to ensure that the overall force of the connecting pin 110 is uniform and safe and reliable.

[0113] Regarding the specific structure of the second elastic component, in a specific embodiment, as Fig.12 , Fig.14 , Fig.15 and Fig.16 As shown, the second elastic component includes a plurality of second springs 113, and at least one second spring 113 is connected between any two circumferentially adjacent second outer shaft sheets 112. When the connecting pin 110 is compressed, two adjacent second outer shaft sheets 112 approach each other and squeeze the second spring 113. On the one hand, the second spring 113 can provide a supporting force to enable the connecting pin 110 to stably support the rotor, and on the other hand, it can also buffer the force impact of the connecting pin 110 and increase the service life of the connecting pin 110.

[0114] The second spring 113 may be a leaf spring, extending along the axial direction of the second inner shaft 111. The leaf spring takes up little space and is easy to install. Of course, the second spring 113 may not be a leaf spring, and multiple structures of this type may be used.

[0115] Two or more second springs 113 may be provided between two circumferentially adjacent second outer shaft pieces 112, and the two or more second springs 113 may be spaced apart in the radial direction of the second inner shaft 111, or spaced apart in the axial direction of the second inner shaft 111. The compression resistance of the connecting pin 110 may be increased, which is conducive to keeping the plurality of second outer shaft pieces 112 in an expanded state, and not prone to partial collapse due to failure of the second springs 113.

[0116] In addition, if Fig.14 , Fig.15 and 16 As shown, at least one of the two circumferentially adjacent end faces of the two circumferentially adjacent second outer shaft pieces 112 is provided with a spring receiving groove 1121, and the second spring 113 can be compressed and embedded in the spring receiving groove 1121, so that the two circumferentially adjacent second outer shaft pieces 112 are in contact with each other in the circumferential direction. The design of the spring receiving groove 1121 is convenient for accommodating the second spring 113, facilitating the full contact of the two adjacent second outer shaft pieces 112, and also conducive to limiting the deformation range of the second spring 113.

[0117] Of course, in other embodiments, the second spring 113 may also be replaced by other structures, such as an elastic rubber member or other damping devices that can achieve this function, which are also within the protection scope of the present application.

[0118] Furthermore, the second elastic component also includes a non-Newtonian fluid layer 114, which is wrapped around the outside of the second inner shaft 111 and can support multiple second outer shaft sheets 112 on the inside. Due to the material properties of non-Newtonian fluids, the greater the torque, the greater the reaction force, so there will be no problem of deformation and disengagement of the connecting pin 110. Moreover, there is no external load torque during installation and disassembly, and plugging and unplugging are extremely easy. During the load-carrying process, due to the characteristics of non-Newtonian fluids, it is strong when encountering rigidity and can transmit force very well. The non-Newtonian fluid layer 114 can buffer the buffering force during the installation of the pin and the rotation process under load.

[0119] Specifically, the non-Newtonian fluid layer 114 can be a polyvinyl chloride layer or a polyethylene layer. Of course, other non-Newtonian fluids can also be used instead (such as concentrated solutions and suspensions of high molecular polymers are generally non-Newtonian fluids. Polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, polyester, rubber solution, various engineering plastics, chemical fiber melts, solutions, etc. are all non-Newtonian fluids. Petroleum, mud, coal-water slurry, ceramic slurry, pulp, paint, ink, toothpaste, silk regeneration solution, drilling fluid and completion fluid, magnetic slurry, coatings of certain photosensitive materials, foams, liquid crystals, high sand content water flow, debris flow, mantle, etc. are also non-Newtonian fluids, etc.).

[0120] In a specific application, the non-Newtonian fluid layer 114 can be nested outside the second inner shaft 111. The non-Newtonian fluid layer 114 is buffered and finally transmits the force to the second inner shaft 111. The second spring 113 is used to connect the plurality of second outer shaft pieces 112 into a whole, and the spring receiving groove 1121 is used to compress and store the second spring 113 after the plurality of second outer shaft pieces 112 are compressed to the minimum.

[0121] Regarding the specific structure of the second spring assembly, in another specific embodiment, the second elastic assembly includes a plurality of second springs. Different from the above structure, each second spring is connected to the outer side of the second inner shaft 111 and the inner side of the second outer shaft sheet 112, and the second spring is used to support the second outer shaft sheet 112. The structure is similar to Fig. 9 When the connecting pin 110 is compressed, the second outer shaft sheet 112 directly presses the second spring inwards to achieve radial change of the connecting pin 110.

[0122] In order to smoothly insert the connecting pin 110 into the insertion hole of the rotor, further, as Fig.13 As shown, the cross-sectional area of ​​one end of the plurality of connecting pins 110 close to the rotatable member is larger than the cross-sectional area of ​​one end of the plurality of connecting pins 110 away from the rotatable member. For example, the plurality of connecting pins 110 are in the form of a cone with one end being larger than the other end. On the one hand, it is convenient for the connecting pins 110 to be smoothly inserted into the corresponding plug holes on the rotor, and on the other hand, it is conducive to making the connecting pins 110 abut against the plug holes, avoiding the connecting pins 110 from moving in the plug holes, thereby facilitating the connecting pins 110 to fully bear the torque and improving the operational reliability of the turning tooling.

[0123] Here, the quasi-axis structure surrounded by the plurality of second outer shaft pieces 112 may be made large at one end and small at the other end, or the quasi-axis structure surrounded by the plurality of second outer shaft pieces 112 and the second inner shaft 111 may be made large at one end and small at the other end.

[0124] During the installation of the connecting pin 110 and the rotor, the small head of the connecting pin 110 is first inserted into the rotor plug hole. At this time, the shaft hole gap is large and there is a problem of eccentricity. When the connecting pin 110 is gradually pushed in (pushed toward the generator end), the second spring 113 is gradually compressed into the spring receiving groove 1121, and the polyvinyl chloride layer is gradually stressed. Because the reaction force is not large during the installation process, the installation can be gradually recommended. The large head of the connecting pin 110 gradually enters the differential control of the rotor to achieve seamless installation. Finally, after the turning structure is installed, all the plug holes and the connecting pin 110 are tightly connected, solving the problem of difficult installation with the same diameter at both ends in the traditional method.

[0125] Furthermore, the plurality of connecting pins 110 and the rotatable member are detachably connected, so that the connecting pins 110 can be easily replaced, and the connecting pins 110 can be prevented from being worn out over a long period of time and affecting the turning gear.

[0126] The connecting pin 110 can contract and expand radially, and is roughly push-shaped, so that the connecting pin 110 can be suitable for connection with different generators. In addition, when the connecting pin 110 can also be detachably connected to the rotatable part, it is also beneficial to replace different connecting pins 110 according to different types of generators, and connect to the ports of different types of generators. The turning tool can be applied to various types of generators, realize the turning function of different manufacturers, different models, and different impeller loads, and greatly increase the versatility of the turning tool. According to the calculation of 1.5 million for a set of turning tool, the development of such a set of universal turning tool with a universal interface can be directly applied to future models above 20MW. It only needs to increase the diameter of the connecting pin 110, the diameter of the locking pin 230, and the torque of the drive motor. The cost is about 100,000, which is equivalent to purchasing a new set of turning tool, reducing costs.

[0127] In addition, the design of the connecting pin 110 of the present invention allows for free combination. In addition to being used to connect the rotor, it is also convenient for universal connection of the interface between the stator and rotor of generators from different manufacturers, and can also be used for the connection of the plug interface of old lifting equipment to achieve cost reduction of the lifting equipment. The connecting pin 110 is universal and multi-purpose, and the pin can adjust the gap radially. Of course, the pin can also be adjusted axially, which is convenient for mass production.

[0128] To prevent the locking pin 230 from breaking, the locking pin 230 can further be radially contracted and expanded. Compared with a rigid structure, the locking pin 230 can buffer the impact force with the inner wall of the insertion hole 211 of the brake disc 210, thereby reducing the probability of the locking pin 230 breaking.

[0129] Regarding the specific structure of the locking pin 230, in some embodiments, as Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the locking latch 230 includes a first inner shaft 231, a plurality of first outer shaft pieces 232, and a first elastic component. The plurality of first outer shaft pieces 232 are circumferentially distributed on the outer side of the first inner shaft 231 to surround the first inner shaft 231. The first elastic component connects the first inner shaft 231 and the plurality of first outer shaft pieces 232. The plurality of first outer shaft pieces 232 can be compressed and contracted to abut against each other in the circumferential direction of the first inner shaft 231 and press the first elastic component inwardly. The plurality of first outer shaft pieces 232 can also expand outward and separate from each other under the elastic force of the first elastic component.

[0130] This structure, which has a first inner shaft 231 inside and a plurality of first outer shaft sheets 232 that can shrink and expand outside, can ensure that the locking pin 230 has a certain structural strength, and can also achieve expansion and contraction, so as to stably support the rotor. Moreover, since the peripheral part is designed as a slice body, the production cost is low, and it can be made of waste scraps to reduce costs. In addition, the periphery of the locking pin 230 adopts a sheet body design, which is used to lock the brake disc 210 in the contracted state and is used for buffering inside the socket 211 of the brake disc 210 in the expanded state, which can ensure that the mechanical structure will not be subjected to unbearable impact loads during instantaneous braking. The shrinkable and expandable locking pin 230 can play a buffering role during installation and load-carrying rotation.

[0131] Figure 8 A side view of the locking latch 230 is shown. Fig. 9 , Fig.10 and Fig.11 They are Figure 8 The figure is a cross-sectional view taken along the PP direction, and is a cross-sectional view of the locking pin 230 in different states. Fig. 9 A cross-sectional view of the locking pin 230 in a natural state without being squeezed is shown. It can be seen that when the locking pin 230 is not squeezed, the cross-section is substantially a perfect circle. Fig.10 The schematic diagram shows the locking pin 230 in the process of being compressed. At this time, the first elastic component is compressed, and two adjacent first outer shaft pieces 232 have not yet completely abutted against each other. Fig.11 The cross-sectional schematic diagram of the locking pin 230 in a compressed state is shown. At this time, any two circumferentially adjacent first outer shaft pieces 232 abut against each other, and the locking pin 230 is compressed to a minimum state.

[0132] In a specific application, during the locking process of the locking pin 230, it first penetrates into the mounting hole on the left side of the brake disc 210, that is, the first avoidance hole 2511 on the bracket 250. At this time, the shaft hole gap is very large and there is a problem of eccentricity. When the locking pin 230 gradually penetrates (pushes toward the right side of the brake disc 210), the first elastic component is gradually compressed and gradually subjected to force. As the brake disc 210 rotates, the position of the locking pin 230 remains fixed, but the diameter is gradually compressed to match the large and small head ends of the socket 211 of the brake disc 210, thereby realizing damping mechanical control braking. Finally, the locking pin 230 and the socket 211 of the brake disc 210 are seamlessly fitted together for braking, thereby realizing the load-bearing braking function.

[0133] During the operation of the turning gear with load, since the first outer shaft sheet 232 is gradually compressed, the greater the reaction force, there will be no problem of deformation and disengagement of the locking pin 230 due to force. The advantage of this structure is that when installing and disassembling, it is only necessary to slightly reverse the brake disc 210 to move the locking pin 230 toward the large end 2111 of the insertion hole 211, and then the locking pin 230 can be pulled out through the locking pin driving member, which is extremely easy to insert and pull out. Moreover, during the operation of the turning gear with load, since the contracted locking pin 230 is roughly in a semi-circular structure, it can well transmit the force, increase the contact area, and have a good locking effect.

[0134] Here, the plurality of first outer shaft pieces 232 can be designed according to the maximum diameter, that is, when the locking pin 230 is observed along the axial direction of the locking pin 230, the connecting line of the outer contours of the plurality of first outer shaft pieces 232 in the natural state without compression is a circle. Therefore, after the first outer shaft pieces 232 are squeezed and contracted, the connecting line of the outer contours of the plurality of first outer shaft pieces 232 is non-circular, with a certain bulge, as shown in FIG. Fig.11 The four bulges of the upper, lower, left and right connecting pin 110 are based on the center position in the figure, similar to the square and circle structure. This structure can ensure the buffer after the shaft hole gap deviation is large. Even if the locking pin 230 rotates, it will get stuck due to the non-circular structure after rotating to a certain angle, thereby ensuring that the locking pin 230 can stably withstand the torque. Fig. 9 and Fig.11 As shown, L1 is the lateral movement space of the first outer shaft piece 232, L2 is the minimum diameter of the first outer shaft piece 232 in a compressed state, L3 is the buffer area of ​​the first outer shaft piece 232, and L4 is the difference between the maximum adaptation diameter and the minimum adaptation diameter of the locking pin 230. Therefore, in order to adapt to different brake discs 210, the size of the buffer area can be set according to the above four parameters to ensure that the overall force of the locking pin 230 is uniform and safe and reliable.

[0135] In addition, the number of the plurality of first outer shaft pieces 232 is at least two, including but not limited to three, four, etc. The number of the first outer shaft pieces 232 can be designed according to actual force requirements, and can be symmetrically or asymmetrically distributed relative to the center line of the first inner shaft 231 .

[0136] In addition, the cross-section of the locking pin 230 in the natural state may be in other shapes besides being roughly circular, such as square, polygonal, etc.

[0137] Furthermore, the locking pin 230 is in a tapered structure with one end being large and the other end being small. The cross-sectional area of ​​the end of the locking pin 230 facing the brake disc 210 is smaller than the cross-sectional area of ​​the end away from the brake disc 210. This facilitates the insertion of the locking pin 230 into the insertion hole 211 and helps ensure that the locking pin 230 abuts against the insertion hole 211. Here, the first inner shaft 231 and the plurality of first outer shaft pieces 232 may both be in a tapered structure, or the first inner shaft 231 may be in a straight cylindrical shape, and the plurality of first outer shaft pieces 232 may be distributed roughly in a tapered shape.

[0138] Regarding the specific structure of the first elastic component, in a specific embodiment, as Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the first elastic component includes a plurality of first springs 233, which are respectively connected to the outer side of the first inner shaft 231 and the inner side of the first outer shaft piece 232. The first springs 233 are used to support the plurality of first outer shaft pieces 232, so as to facilitate radial compression under pressure. Moreover, since the first springs 233 are located between the first inner shaft 231 and the outer shaft piece, there will be no interference problem between the plurality of first outer shaft pieces 232 during the contraction and expansion process of the locking pin 230. Moreover, the elastic force of the spring is relatively large, and a relatively large supporting force can be provided to cause the locking pin 230 to be closely contacted with the insertion hole 211, thereby improving the locking effect and buffering the impact borne by the locking pin 230.

[0139] The first spring 233 may be a leaf spring, extending along the axial direction of the first inner shaft 231. The leaf spring takes up little space and is easy to install. Of course, the first spring 233 may not be a leaf spring, and multiple structures of this type may be used.

[0140] In addition, one, two or more first springs 233 may be provided between each first outer shaft piece 232 and the first inner shaft 231. The two or more first springs 233 may be spaced apart in the circumferential direction of the first inner shaft 231, or spaced apart in the axial direction of the first inner shaft 231. The compression resistance of the locking pin 230 may be increased, which is conducive to keeping the plurality of first outer shaft pieces 232 in an expanded state, and not prone to local collapse due to failure of the first springs 233.

[0141] Of course, in other embodiments, the first spring 233 may be replaced by other structures, such as a first rubber pad or other damping device that can achieve this function, which is also within the protection scope of the present application. Based on the situation that the first elastic component includes a plurality of first rubber pads, the first rubber pad may be in the shape of an elongated strip, extending along the axial direction of the first inner shaft 231, and at least one first rubber pad is connected between each first outer shaft sheet 232 and the first inner shaft 231 in the circumferential direction of the first inner shaft 231.

[0142] Regarding the specific structure of the first elastic component, in another specific embodiment, the first elastic component includes a plurality of first springs, and at least one first spring is connected between any two circumferentially adjacent first outer shaft pieces 232. The first elastic component also includes a non-Newtonian fluid layer, which is wrapped around the outside of the first inner shaft 231 and can support the plurality of first outer shaft pieces 232 on the inside. Due to the material properties of the non-Newtonian fluid, the greater the torque, the greater the reaction force, and it is rigid when encountering rigidity, and it has a buffering effect while ensuring a braking effect.

[0143] Regarding the specific structure of the bracket 250, further, as Figure 4 , Figure 5 and Figure 6 As shown, the bracket 250 includes a first baffle 251 and a second baffle 252, which are respectively located on both sides of the brake disc 210, a first avoidance hole 2511 is provided on the first baffle 251, and a second avoidance hole 2521 is provided on the second baffle 252. The insertion hole 211 is a through hole, and the locking pin 230 can pass through the insertion hole 211 through the first avoidance hole 2511 and then be inserted into the second avoidance hole 2521. The locking pin 230 is inserted into the two baffles and the brake disc 210 at the same time, which can effectively limit the brake disc 210 and has a good locking effect.

[0144] Of course, in other examples, the bracket 250 may also include only the first baffle 251 or the second baffle 252, and the insertion hole 211 may be a countersunk hole in addition to a through hole, and the locking pin 230 extends from the avoidance hole on one side of the brake disc 210 into the countersunk hole to lock the brake disc 210. Since the insertion hole 211 is a countersunk hole, it has little effect on the structural strength of the brake disc 210, which is conducive to bearing a larger torque.

[0145] The following describes a second aspect of the present invention, which provides a control method for a turning tool, and is used for the turning tool in the first aspect of the present invention. The control method includes the following steps:

[0146] Receive a start command and control the brake disc 210 to rotate;

[0147] The rotation parameters of the rotatable member and / or the rotation parameters of the brake disc 210 are acquired, and based on the acquired rotation parameters, the locking pin 230 is controlled to be inserted into the insertion hole 211 of the brake disc 210 .

[0148] Furthermore, the turning tool further includes a brake caliper 240 for performing friction braking on the brake disc 210 , and the control method further includes: controlling the brake caliper 240 to engage the brake based on the acquired rotation parameters.

[0149] In a specific embodiment, Fig.18 As shown, the control method of the turning tool comprises the following steps:

[0154] When any one of the rotation parameters of the rotatable part and the rotation parameter of the brake disc 210 is higher than the corresponding set range, the brake caliper 240 is controlled to engage the brake, and the locking pin 230 is controlled to be inserted into the insertion hole 211 of the brake disc 210 during the deceleration process of the brake disc 210.

[0155] Further, the step of obtaining the rotation parameters of the brake disc 210 includes: obtaining the time required for the brake disc 210 to rotate a set angle. The step of obtaining the rotation parameters of the rotatable part includes: obtaining the rotation angle of the rotatable part within the set time.

[0156] Furthermore, after the step of controlling the brake disc 210 to continue rotating, the method further includes: after the brake disc 210 is controlled to rotate to a specified angle, the brake caliper 240 is controlled to engage the brake, and the locking pin 230 is controlled to be inserted into the socket 211 on the brake disc 210 to ensure that the brake disc 210 does not continue to rotate.

[0157] Furthermore, after the step of controlling the brake caliper 240 to engage the brake, the method further includes: after the brake disc 210 stops rotating, controlling the locking pin 230 to be inserted into the insertion hole 211 on the brake disc 210 to ensure that the brake disc 210 does not continue to rotate.

[0158] In another specific embodiment, Fig.19 As shown, the control method of the turning tool comprises the following steps:

[0159] Receive a start command and control the brake disc 210 to rotate;

[0160] Obtaining the rotation parameters of the rotatable member and the rotation parameters of the brake disc 210;

[0161] When the rotation parameter of the brake disc 210 is within the first setting range and the rotation parameter of the rotatable member is within the second setting range, the brake disc 210 continues to be driven to rotate at a preset speed;

[0162] When the rotation parameter of the brake disc 210 is not within the first setting range, or the rotation parameter of the rotatable part is not within the second setting range, the brake disc 210 is driven to rotate at a speed lower than the preset speed, and the brake caliper 240 is controlled to engage the brake;

[0163] When the rotation parameter of the brake disc 210 is not within the first set range and the rotation parameter of the rotatable part is not within the second set range, the brake disc 210 is stopped from being driven to rotate, the brake caliper 240 is controlled to engage, and the locking pin 230 is controlled to be inserted into the socket 211 of the brake disc 210 during the deceleration process of the brake disc 210.

[0164] Further, the step of obtaining the rotation parameters of the brake disc 210 includes: obtaining the time required for the brake disc 210 to rotate a set angle. The step of obtaining the rotation parameters of the rotatable part includes: obtaining the rotation angle of the rotatable part within the set time.

[0165] Furthermore, after the step of controlling the brake disc 210 to continue rotating, the method further includes: after the brake disc 210 is controlled to rotate to a specified angle, the brake caliper 240 is controlled to engage the brake, and the locking pin 230 is controlled to be inserted into the socket 211 on the brake disc 210 to ensure that the brake disc 210 does not continue to rotate.

[0166] Furthermore, after the step of controlling the brake caliper 240 to engage the brake, the method further includes: after the brake disc 210 stops rotating, controlling the locking pin 230 to be inserted into the insertion hole 211 on the brake disc 210 to ensure that the brake disc 210 does not continue to rotate.

[0167] The present embodiment combines dual protection control logic, detects the rotation of the rotatable parts and the rotation of the brake disc 210 at the same time, and controls the rotation of the brake disc 210 in multiple ways. It can timely monitor whether there is a problem with the turning wheel and lock the brake disc 210, thereby improving the safety and controllability of the turning wheel tooling carrying the turning wheel.

[0168] The following is a detailed description of a turning tool of an embodiment of the present invention. The turning tool provides a connecting pin 110 that can be radially contracted and expanded, a turning tool load locking mechanical structure, and a turning tool load control logic, which can be applied to the impeller load mechanical locking and electrical control logic of medium-speed permanent magnet units, semi-direct drive units, and direct drive units.

[0169] The following describes the components and their functions in the turning tooling. Figure 3 As shown, the second transmission gear 320 is provided with a mounting hole on its upper part. The connecting pin 110 is characterized by a conical structure and can shrink and expand in the radial direction, so as to realize seamless connection with the plug hole on the generator rotor. The support seat 60 is provided with a support shaft 610, and the support shaft 610 is sleeved with a shaft sleeve 620 and an end face flange 630. The end of the support shaft 610 is inserted into the center hole of the second transmission gear 320 and fixed, so that after the second transmission gear 320 rotates, the whole gear 320 is driven to rotate. The connecting shaft 212 is installed on the brake disc 210, and the front end of the brake disc 210 is provided with a first transmission gear 310, and the first transmission gear 310 is meshed with the second transmission gear 320 to transmit power. The bracket 250, a part of the brake disc 210 is located inside the bracket 250. The brake caliper 240 is arranged on the bracket 250, and is used for friction braking of the brake disc 210. The brake disc 210 and the brake caliper 240 are used for load adjustment and stepless mechanical control of the turning wheel rotation structure. The brake disc drive 220 includes two drive motors and two gear boxes. There are two brake discs 210. The connecting shafts 212 on the two brake discs 210 are connected to a drive motor via a gear box respectively, so that the drive motor drives the brake disc 210 to rotate via the gear box. The two drive motors can be driven at the same time, or one of them can be driven independently. They can be operated at full power to rotate the brake disc 210 at a preset speed, or they can be operated at half power to rotate the brake disc 210 at half the speed, ensuring that the driving force meets the redundancy requirements. The gearbox is used to adjust the reduction ratio to achieve torque load adjustment. At the same time, the rotation parameters of the second transmission gear 320 are monitored by a rotary encoder, and the rotation parameters of the brake disc 210 are monitored by a laser sensor. Double detection and redundant feedback control ensure that the load adjustment logic control of the winch is meticulous and that no safety problems occur. The protective cover 70 is used to protect the mechanical structure of the winch tooling against rain and corrosion, and the structure can be adapted to the size and shape of the box. Reference Figure 3 The second transmission gear 320 , the brake disc 210 , the brake caliper 240 , the brake disc driving member 220 and other structures are all arranged on the inner side of the protective cover 70 .

[0170] The turning tooling proposed in this embodiment, the connecting pin 110 can be used to meet the connection requirements of generator ports of different models, ensuring smooth installation of interfaces of different models. At the same time, the connecting pin 110 is evenly stressed, and the problem of single pin breakage will not occur. This structure is relatively important. Due to the trend of reducing costs, all main engine manufacturers currently cancel the brake disc 210 structure of the original unit. Once the pin connected to the generator breaks, the impeller rotation will become uncontrollable. This embodiment can perfectly solve this problem through the design of a conical connecting pin 110. In addition, since the current unit does not have a brake disc 210, all braking needs to be borne by the turning machine tooling body. Therefore, the present structure is designed with a micro brake disc 210 structure, specifically a self-locking brake disc 210 structure. Through the design of the brake disc 210 socket 211 and the locking pin 230, the brake disc 210 is used to slow down the rotation speed of the loaded turning machine. At the same time, through the evenly distributed specific socket 211 hole position, the locking pin 230 is inserted from the big head end 2111, and with the help of the rotation of the brake disc 210, the locking pin 230 is squeezed to achieve buffered locking of the pin. At the same time, the hole position of the socket 211 becomes smaller. After the buffer zone ends, it can be accurately positioned and locked to ensure the safe locking of the turning machine with load. At the same time, a sensor monitors the angular interval of the second transmission gear 320 rotating for a specific time, and another sensor monitors the time interval used for the brake disc 210 to rotate at a specific angle, thereby controlling the insertion and withdrawal of the locking pin 230 and the full-power and reduced-power operation of the brake disc drive 220, thereby logically providing safe and controllable protection, ensuring automatic control of the brake wheel with load, and reducing the risk of human error.

[0171] Specifically, when the turning tool fails to load, the hydraulic drive structure (a type of clamp drive) first drives the brake caliper 240 to engage the brake, so that the rotation speed of the brake disc 210 decreases, and at the same time, the feedback control module drives the locking pin 230 to start pushing forward. The brake disc 210 can be provided with 6-8 pairs of sockets 211, which are used to achieve mechanical locking of the locking pin 230 at different angles. After the locking pin 230 penetrates the first avoidance hole 2511 on one side of the bracket 250, it passes through the socket 211 on the brake disc 210 and is inserted into the avoidance hole on the other side of the bracket 250 to achieve mechanical locking of the brake disc 210. Preferably, the number of the locking pins 230 is more than two, which are redundant with each other, and a single locking pin 230 itself can withstand the mechanical locking of the turning tool load.

[0172] The specific implementation process is as follows: when the detection module detects that the turning wheel has a fault, the brake caliper 240 starts to brake, and the friction resistance of the brake disc 210 increases. At the same time, the locking pin 230 penetrates into the brake disc 210 and the bracket 250. At this time, the brake disc 210 continues to rotate. After the locking pin 230 penetrates into the inside of the insertion hole 211 of the brake disc 210 (the large hole is designed to facilitate the smooth insertion of the locking pin 230), as the turning wheel tooling continues to rotate, the locking pin 230 is gradually compressed, and the first outer shaft piece 232 is gradually compressed and stressed, shrinking inward, and even forming a solid pin structure. When the position size corresponding to the insertion hole 211 and the locking pin 230 gradually becomes smaller, the force on the locking pin 230 gradually increases. At the same time, under the action of the continued rotation of the brake disc 210 under force, the loaded turning wheel can be quickly braked, and the self-locking function can be realized. At the same time, the rotation angle is very small, dispersed to more than 100 of the gearbox transmission ratio, and the rotation angle of the impeller end is negligible, which can be considered to be a static state, thereby ensuring the safety of personnel working in the hub 80.

[0173] The following is an explanation of the example of the winching of the winching tool during the process of hoisting the blade 90. First, power is supplied from the deck and the brake disc drive 220 is turned on. After the self-inspection of the winching tool is completed, the winching tool can be lifted to be installed with the plug holes on the generator rotor of the unit. The plug holes are usually 4, 6 or 8 evenly distributed. The connecting pin 110 is plugged into the plug holes. Usually after the connecting pin 110 is installed, there will be a bolt connection. Since the rotational torque is mainly borne by the shear of the connecting pin 110, the bolt only needs to bear the axial weight of the winch itself. The method is relatively common and will not be described in detail in this solution. It is sufficient to fix the winching tool itself. Reference Fig.17 After the installation of the turning tool is completed, the blade 90 can be lifted, and the hub 80 interface of the turning tool for installing the blade 90 can be rotated to a horizontal level (this process is no-load). When the blade 90 is lifted to the position, the blade 90 is docked. When the bolt torque of the blade 90 is tightened, the blade 90 clamp can be loosened. At this time, the turning tool starts to rotate with load and rotates normally. This is a normal working condition and will not be described in detail. When the turning tool is abnormal under load, the rotary encoder and the laser sensor control the brake clamp 240 through signal feedback, and at the same time control the locking pin 230 to penetrate into the brake disc 210, and adjust the operating power of the brake disc drive 220 to prevent overload of the connecting shaft 212, so as to ensure that the loaded turning tool is braked quickly and smoothly, and to ensure the safety of the operator and the unit construction personnel. When the turning gear failure is eliminated, the locking pin 230 is pulled out again, the brake caliper 240 is opened, and the wheel hub 80 is driven to rotate again through the brake disc 210, the first transmission gear 310, the second transmission gear 320, and the rotor. The brake caliper 240 is driven by a hydraulic drive, and the electrical control of the brake disc drive 220 and the locking pin 230 is a separate circuit for redundant protection. If one circuit fails, the other circuit continues to keep locked.

[0174] The control part of this embodiment has high stability through mature sensor technology and feedback mechanism, and is combined with the redundant protection of the brake disc drive 220 to achieve stepless locking during the braking process of the loaded disc car, and can hover at a set angle to achieve precise control and ensure the safety of on-site operators and hoisting personnel. The mechanical structure of this embodiment has low manufacturing cost, simple electrical control components, high efficiency, mature principles, and greatly reduces the requirements for safety, reliability, and low cost in the development process of the disc car tooling. This solution can be applied to medium-speed permanent magnet units, as well as direct-drive units and double-fed units. As long as the generator end and the pin structure are connected, the loaded disc car, drive and locking functions can be realized, and the application prospects are broad.

[0175] The turning tool provided in this embodiment can solve the problem that the turning tool on the market cannot monitor and lock the turning tool in real time after the turning tool fails. It can also solve the safety problem of the large circumferential space of the drive shaft and the lack of redundant locking in the current electric-driven turning tool, and solve the problem of oil leakage risk and load stall in the current hydraulic-driven turning tool.

[0176] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention defined by the claims.
