However, in the actual application process, how to efficiently and reliably realize the input and output of the turning device has become a technical problem that needs to be solved urgently.
[0003] At present, the commonly used winch devices mainly use power sources such as cylinders or electric motors in conjunction with connecting rod mechanisms to achieve the winch engagement and disengagement functions. Existing technical means mainly include the use of multi-stage connecting rod mechanisms and cylinder linkage to achieve the engagement and disengagement of winch gears; the other is to use a combination of springs and connecting rod mechanisms to provide necessary auxiliary functions during the engagement and disengagement process. In addition, some technologies use hydraulic control systems in conjunction with mechanical transmissions to achieve automatic engagement and disengagement of the winch. Although these means can meet engineering and technical requirements to a certain extent, there are still some defects in actual application.
[0004] In the prior art, the engagement between the turning gear and the rotor gear is axial engagement, that is, the turning gear moves linearly along the axial direction of the rotor to engage with the rotor gear, and the linear movement is completed by sliding on the threaded groove on the turning gear engaging gear shaft.

[0050] The connecting rod mechanism 5 includes an active connecting rod assembly 51 arranged on the housing 1 for driving the mounting seat 2 to rotate, and an assisting connecting rod assembly 52 arranged on the housing 1 for assisting the operation of the active connecting rod assembly 51. The housing 1 is also provided with a separation and engagement retaining assembly 53 for engaging or disengaging the swing gear set 3 with the rotor gear, which cooperates with the multi-stage connecting rod mechanism 5 so that the swing gear set 3 and the rotor gear engage or disengage with each other, and the engagement state is more stable and the disengagement state is more thorough, thereby reducing the occurrence of tooth collision problems; the active connecting rod assembly 51 and the assisting connecting rod assembly 52 ensure the reliability and stability of the winch device when linked.
[0051] See also Figure 3As shown, the active connecting rod assembly 51 includes a crank arm 511 rotating on the housing 1, a connecting rod 512 hinged at one end of the crank arm 511 away from the second driving assembly 6, a driving fork 513 hinged at one end of the connecting rod 512 away from the crank arm 511, a control fork 514 rotatably connected to the housing 1 for use with the driving fork 513, a pull rod fork 515 coaxially fixed with the control fork 514, and a pull rod 516 hinged at one end of the pull rod fork 515 away from the control fork 514, wherein the length of the pull rod 516 is greater than the length of the pull rod fork 515. It is set at an acute angle to the pull rod fork 515, the pull rod 516 is hinged to the mounting seat 2, a fork shaft 517 is rotatably set on the box body 1, the control fork 514 and the pull rod fork 515 are coaxially connected to the fork shaft 517, the control fork 514 and the pull rod fork 515 are set at an obtuse angle; the length of the crank arm 511 is greater than the length of the connecting rod 512, the crank arm 511 and the connecting rod 512 are set at an obtuse angle, and the length of the driving fork 513 is greater than the length of the connecting rod 512; the use of a multi-stage connecting rod mechanism 5 improves the coordination of the overall turning gear and ensures the reliability of the linkage between the connecting rods.
[0052] When the second driving assembly 6 acts on the crank arm 511, the crank arm 511 in the housing 1 rotates clockwise, the connecting rod 512 moves along the driving fork 513, the driving fork 513 rotates clockwise, the control fork 514 and the pull rod fork 515 both rotate counterclockwise along the fork shaft 517, the pull rod 516 moves toward the mounting seat 2, the swing gear set 3 swings clockwise, and the swing gear set 3 and the rotor gear form a meshing state;
[0053] The swing gear set 3 swings counterclockwise, the pull rod 516 moves away from the mounting seat 2, the control fork 514 and the pull rod fork 515 both rotate clockwise along the fork shaft 517, the driving fork 513 rotates counterclockwise, the connecting rod 512 moves away from the driving fork 513, the crank arm 511 rotates counterclockwise, and the swing gear set 3 and the rotor gear form a separation state;
[0054] The rotor gear is the gear on the turbine rotor. The process of cranking is that the swing gear set 3 of the cranking device is meshed with the rotor gear. The cranking starts to drive the turbine rotor to rotate. When the turbine starts to run (the turbine starts to drive the generator to start generating electricity, and the turbine speed is generally 3000 rpm), the cranking device needs to exit from the meshing state;
[0055] See also Figure 2 and Figure 4As shown, the power-assist connecting rod assembly 52 includes a separation driving fork 521 rotating on the housing 1, and a separation micro-driving push rod 522 rotatably connected to the separation driving fork 521, the separation driving fork 521 and the driving fork 513 are coaxially connected, and one end of the separation micro-driving push rod 522 away from the driving fork 513 is slidably matched with the separation and combination holding assembly 53, the length of the separation driving fork 521 is less than the length of the separation micro-driving push rod 522, and the separation driving fork 521 and the separation micro-driving push rod 522 are arranged at an obtuse angle; a pair of waist-shaped grooves are provided on the separation driving fork 521, and a locking pin is arranged through the waist-shaped groove, and the locking pin passes through the waist-shaped groove and is locked with the housing 1, and a spring is provided on the structure sleeve of the locking pin at the bottom of the waist-shaped groove, one end of the spring is against the separation driving fork 521, and the other end of the spring is against the bottom end of the locking pin, so that the coaxially connected separation driving fork 521 and the driving fork 513 always maintain a close contact state.
[0056] See also Figure 4 and Figure 5 As shown, the separation and combination holding assembly 53 includes a torque shaft 531 rotating on the box body 1, a torque sleeve 532 fixed on the torque shaft 531, and a linkage rod 533 hinged on the torque sleeve 532. The end of the linkage rod 533 away from the torque sleeve 532 is hinged to the crank arm 511. An angle adjustment block 534 is also provided on the outer wall of the box body 1. A holding member 535 is fixedly provided on the side of the torque shaft 531 passing through the box body 1. The end of the holding member 535 away from the torque shaft 531 is rotatably set on the angle adjustment block 534. The axis of the angle adjustment block 534 and the torque shaft 531 forms a dead point line 536, see Figure 6 and Figure 7 As shown, the retaining member 535 rotates counterclockwise along the angle adjustment block 534 to form an engagement position 537, and the retaining member 535 rotates clockwise along the angle adjustment block 534 to form a separation position 538, and the angle between the separation position 538 and the dead point line 536 is greater than the angle between the engagement position 537 and the dead point line 536.
[0057] See also Figure 7 and Figure 8 As shown, the retaining member 535 includes a fixed ring 5351 rotatably arranged on the angle adjustment block 534 and a frame 5352 arranged on the fixed ring 5351. A rotating rod 5353 is rotatably arranged on one end of the frame 5352 away from the fixed ring 5351. The rotating rod 5353 is connected to the torque shaft 531, so that one end of the frame 5352 and the angle adjustment block 534 can be limited and rotated, and the other end of the frame 5352 swings in an arc along the center of the angle adjustment block 534, thereby realizing the separation position 538 or the engagement position 537.
[0058] The structure of the frame 5352 is provided with a tension spring arranged along the axial direction, and the dead point line 536 is the line connecting the centers of the two fulcrums of the tension spring. When the frame 5352 is located at the position of the line, the tension spring of the separation and combination holding assembly 53 cannot make the torque shaft 531 rotate in either clockwise or counterclockwise direction. When the tension spring is on the left side of the dead point line 536, the spring force of the tension spring is the force that makes the torque shaft 531 rotate clockwise; when the tension spring is on the right side of the dead point line 536, the force of the tension spring is the force that makes the torque shaft 531 rotate counterclockwise. During the engagement process of the winch, the torque shaft 531 drives the rotating rod 5353 to overcome the clockwise rotation force of the tension spring and rotate from the separation position 538 to the engagement position 537. When bypassing the dead point line 536 to reach the engagement position 537, the spring force changes direction, and its force becomes counterclockwise. This force enables the winch to remain in the engagement position 537. When the engagement is in place, the cylinder 61 driving the gear engagement is depressurized. Fig.11 As shown, return springs are arranged on both sides of the cylinder 61, and the cylinder 61 returns to the position as shown in FIG. Fig.11 position, and under the action of the spring force of the separation and combination holding assembly 53, the turning gear can still be maintained in the meshing position 537. At this time, there is no pressure from the cylinder 61 to force the turning gear to the meshing position 537. Only the spring force of the separation and combination holding assembly 53 keeps the turning gear in the meshing position 537.
[0059] During the automatic separation of the turning gear, the rotor rushes, and the rotor gear changes from a passive gear to a driving gear, and the speed gradually increases. Under the action of centrifugal force, the torque shaft 531 rotates clockwise, and the rotating rod 5353 rotates clockwise with the torque shaft 531 as the center, overcoming the spring force, bypassing the dead point line 536, and the direction of the spring force changes. Under the action of the spring force, the turning gear is pulled back to the separation position 538. According to the different modules of the gears, the full tooth height is different. When the rotor gear and the turning gear gear are separated to the tooth top position, the tension spring must bypass the dead point line 536. Because the rotor gear and the turning gear gear are about to be completely separated at this time, the centrifugal force will no longer exist, and the turning gear needs to be pulled to the separation position 538 by the conversion of the spring force. The size of the dead point angle is set according to the module and the full tooth height of the rotor gear, and is adjusted by the adjustment block.
[0060] See also Fig. 9As shown, the second driving assembly 6 includes a cylinder 61 arranged on the box body 1, and a main fork head 62 is arranged on the piston rod of the cylinder 61, and pull ears 63 are slidably provided on both sides of the main fork head 62, and a movable groove 65 for the pull ears 63 to slide is opened in the main fork head 62, and a roller sleeve shaft 64 is arranged at one end of the main fork head 62 away from the cylinder 61. The opened movable groove 65 requires that when the piston rod of the cylinder 61 is started, the stroke of the movable groove 65 needs to be eliminated so that the roller sleeve shaft 64 and the crank arm 511 can be abutted, so that there will be a certain time for the cylinder 61 to compress and discharge the air before the impact, and the piston rod of the cylinder 61 will slide along the movable groove 65 to the middle position of the movable groove 65 with the pull ears 63 on both sides, so as to prepare for the impact before the impact.
[0061] The swing gear set 3 includes an idle gear 31 rotatably set on the mounting seat 2 and a power output gear 32 meshing with the idle gear 31. The power output gear 32 and the side wall of the housing 1 are rotationally matched. During the swinging process, the mounting seat 2 drives the idle gear 31 to swing, thereby realizing radial engagement and separation between the idle gear 31 and the rotor gear; the swing gear set 3 meshes in a radial manner, and the swing gear set 3 moves along the radial direction of the rotor gear by a certain angle to complete the engagement. The engagement is completed by the swinging of the connecting rod mechanism 5, which makes it insensitive to foreign matter and effectively reduces the risk of the external driving force not being able to withdraw in time when the rotor is running.

[0064] The implementation principle of an automatic separation type winch device in the embodiment of the present application is as follows: during the winch operation: the piston rod of the cylinder 61 moves downward, the active connecting rod assembly 51 located inside the housing 1 rotates clockwise, the power-assist connecting rod assembly 52 and the active connecting rod assembly 51 rotate clockwise along the coaxial axis, the crank arm 511 is acted upon by the roller sleeve shaft 64 on the piston rod of the cylinder 61, the crank arm 511 drives the connecting rod 512 to move toward the driving fork 513, the driving fork 513 rotates clockwise, at this time, the control fork 514 matched with the driving fork 513 rotates counterclockwise along the axis of the fork shaft 517, the pull rod fork 515 coaxially connected to the fork shaft 517 also rotates counterclockwise, the pull rod fork 515 drives the pull rod 516 to move downward, the mounting seat 2 swings clockwise, so that the idler gear 31 located on the mounting seat 2 meshes with the rotor gear, and the driving fork 513 is separated. 21 and the driving fork 513 make the active connecting rod assembly 51 and the auxiliary connecting rod assembly 52 always fit together through the force of the right locking pin and the spring, and the linkage rod 533 drives the separation micro-drive push rod 522 to slide close to the torque shaft 531. At the same time, the torque shaft 531 rotates counterclockwise under the action of the separation micro-drive push rod 522, and the retaining member 535 rotates counterclockwise under the drive of the torque shaft 531, and bypasses the center line of the torque shaft 531 and the angle adjustment block 534, so that the retaining member 535 is maintained in the meshing position 537; after the meshing signal is sent, the turning device is started, and when the rated speed is reached, the cylinder 61 compresses and discharges the air, and the piston rod of the cylinder 61 returns to the middle position of the movable groove 65 to prepare for the impact rotation. If the phenomenon of tooth collision occurs during the meshing process, the motor 44 rotates at a low frequency and low speed for a meshing angle to mesh again.
[0065] During the withdrawal process of the turning device, the rotor rotates, the gear on the rotor changes from a passive wheel to an active wheel, the turning idler gear 31 moves under the action of centrifugal force, the mounting seat 2 swings counterclockwise, the pull rod 516 moves upward, the pull rod fork 515 and the control fork 514 rotate clockwise along with the fork shaft 517, the driving fork 513 rotates counterclockwise under the influence of the control fork 514, the connecting rod 512 moves toward the side of the crank arm 511, the crank arm 511 rotates counterclockwise, and the linkage rod 533 drives the separation micro-drive push rod 522 to slide toward the torque shaft 531. The torque shaft 531 rotates clockwise, and the retaining member 535 rotates clockwise around the dead point line 536 driven by the torque shaft 531, and the turning gear idler gear 31 and the rotor gear are withdrawn from the meshing state under the action of the spring force. At this time, the power-assisting connecting rod assembly 52 plays an auxiliary withdrawal role. The active connecting rod assembly 51 is not sufficient to make the power-assisting connecting rod assembly 52 amplify the signal when the turning gear is withdrawn, driving the separation micro-drive push rod 522 to slide toward the direction close to the torque shaft 531, and ejecting the withdrawal pin on the torque shaft 531, thereby causing the torque shaft 531 to rotate clockwise.
