[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0046] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0047] It should be noted that the following orientation terms such as "left and right" are defined based on the accompanying drawings of the specification.

[0048] The core of the present utility model is to provide a pitch bearing hoisting tooling, which can be applicable to the hoisting of pitch bearings 01 with different diameters and can adjust the hoisting angle, thereby effectively improving the assembly quality of the pitch bearings 01.

[0049] Please refer to Figure 1 and Figure 2 , a pitch bearing hoisting tooling includes a tooling body 1, an adjusting sleeve 2, a slide rail 3, a slider 4, a sling 5, a shackle 6, a hinge seat 7, a driving assembly 8, an angle sensor 9 and a controller.

[0050] Specifically, one end of the tooling body 1 connected to the pitch bearing 01 is provided with an adjusting sleeve 2 for adjusting the connection point to realize the hoisting of pitch bearings 01 with different diameters and improve the versatility of the tooling. One end of the tooling body 1 far from the pitch bearing 01 is provided with a slide rail 3 extending along the axial direction of the pitch bearing 01. A slider 4 is arranged on the slide rail 3, and a hinge seat 7 hinged to the shackle 6 of the sling 5 is arranged on the slider 4. When the center of gravity of the pitch bearing 01 and the sling 5 are on the same line, the slider 4 is located in the middle of the slide rail 3. At this time, the included angle between the center of gravity of the pitch bearing 01 and the end face of the pitch bearing 01 is 0 degree. That is to say, the hoisting angle of the pitch bearing 01 in this position is 0 degree, and this is used as the 0 reference line for adjusting the hoisting angle of the pitch bearing 01.

[0051] The driving component 8 is arranged on the tooling body 1 and is signal-connected to the controller. The driving component 8 is used to drive the slider 4 to slide along the slide rail 3. By controlling the operation of the driving component 8 through the controller, the slider 4 is driven to move along the slide rail 3, thereby driving the pitch bearing 01 to move synchronously, so that the center of gravity of the pitch bearing 01 deflects, so as to change the hoisting angle of the pitch bearing 01, so that the hoisting posture of the pitch bearing 01 can be adjusted more accurately, and then the assembly quality of the pitch bearing 01 is improved. The angle sensor 9 is arranged on the slider 4 and is signal-connected to the controller. The angle sensor 9 is used to monitor in real time the included angle between the center of gravity of the pitch bearing 01 and the end face of the pitch bearing 01. By monitoring in real time the change of the included angle between the center of gravity of the pitch bearing 01 and the end face of the pitch bearing 01 through the angle sensor 9, and sending the monitored included angle signal of the deflection of the center of gravity of the pitch bearing 01 to the controller. By judging the difference between the included angle signal and the actual included angle degree of the installed pitch bearing 01 through the controller, until the angle of deflection of the pitch bearing 01 monitored in real time by the angle sensor 9 is consistent with the actual installation angle, the controller controls the driving component 8 to stop running.

[0052] For the pitch bearing hoisting tooling arranged in the above manner, by setting the adjusting sleeve 2, it is applicable to the hoisting of pitch bearings 01 with different diameters. By means of the driving component 8 plus the slider 4, the hoisting angle of the pitch bearing 01 can be adjusted more accurately.

[0053] Please refer to Figure 2 、 Figure 3 and Figure 4 The driving component 8 includes a servo motor 81 and a speed reducer 82 connected to the servo motor 81. Both the servo motor 81 and the speed reducer 82 are signal-connected to the controller. The output shaft of the speed reducer 82 is connected to a ball screw assembly 84 through a coupling 83, and the ball screw assembly 84 is connected to the slider 4.

[0054] It should be noted that by controlling the running state of the servo motor 81 through the controller, and further decelerating the power output by the servo motor 81 through the speed reducer 82 to control the output power of the servo motor 81. The power is transmitted to the ball screw assembly 84 through the coupling 83, driving the ball screw assembly 84 to run, and making the slider 4 move along the slide rail 3.

[0055] The ball screw assembly 84 of the present application converts rotary motion into linear motion, which is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial reciprocating force, and at the same time has the characteristics of high precision, reversibility and high efficiency. Due to having very small frictional resistance, it is widely used in various industrial equipment and precision instruments.

[0056] In the above situation, the ball screw assembly 84 includes a screw rod and a nut movably sleeved on the screw rod. One end of the screw rod is connected to the coupling 83, and the other end of the screw rod is rotatably connected to the side plate 113 of the tooling body 1. The slider 4 is connected to the nut.

[0057] It can be understood that by controlling the operation of the servo motor 81 through the controller, the output is transmitted through the reducer 82, and the power is transmitted to the screw rod through the coupling 83, driving the screw rod to rotate synchronously, thereby driving the nut on the screw rod to move axially along the screw rod, so as to drive the slider 4 to move synchronously along the slide rail 3.

[0058] Furthermore, a scale 31 is provided on the slide rail 3, and the 0 graduation line of the scale 31 is located in the middle of the slide rail 3.

[0059] It should be noted that the graduation line of the scale 31 is located in the middle of the slide rail 3. When the slider 4 is located at the 0 graduation line, the included angle between the center of gravity of the pitch bearing 01 and the end face of the pitch bearing 01 is 0 degree. Among them, the deflection angle brought by the moving stroke of the slider 4 along the slide rail 3 is 7 - 8 degrees. In practical applications, there is no limit to the deflection angle, which can be customized according to the actual situation.

[0060] In practical applications, there is no limit to the accuracy of the scale 31, as long as the above technical effects can be achieved.

[0061] In the above embodiment, the tooling body 1 includes a first main body part 11 and a second main body part 12. The first main body part 11 is detachably connected to the second main body part 12. The first main body part 11 is used to connect the sling 5, and the second main body part 12 is used to connect the pitch bearing 01.

[0062] It can be understood that the first main body part 11 and the second main body part 12 are set as a detachable structure to facilitate the disassembly and assembly of the sling 5 and the pitch bearing 01.

[0063] On the basis of the above embodiment, the first main body part 11 includes a U-shaped structure 111 connected to the second main body part 12. One side of the U-shaped structure 111 is provided with an end plate 112 for installing the reducer 82, and the other side of the U-shaped structure 111 is provided with a side plate 113.

[0064] It should be noted that the effective connection to the second main body part 12 is achieved by setting the U-shaped structure 111. An end plate 112 is provided at one end of the U-shaped structure 111, and a side plate 113 is provided at the other end of the U-shaped structure 111 to realize the installation of the reducer 82 and at the same time provide support for the rotation of the screw rod.

[0065] Please refer to Figure 5 and Figure 6, the second main body 12 includes a first connecting portion 121 connected to the U-shaped structure 111, and further includes second connecting portions 122 vertically provided on both sides of the first connecting portion 121. The second connecting portions 122 are arranged in a trapezoidal structure. A trapezoidal groove 1221 extending circumferentially along the pitch bearing 01 is provided on the second connecting portions 122. A detachable adjusting sleeve 2 is provided in the trapezoidal groove 1221. The adjusting sleeve 2 is connected to the pitch bearing 01 through a mounting bolt pair.

[0066] It can be understood that during installation, the first connecting portion 121 of the second main body 12 is connected to the U-shaped structure 111, and the second connecting portion 122 is connected to the pitch bearing 01.

[0067] Among them, the second connecting portion 122 is arranged in a trapezoidal structure to adapt to the radian of the pitch bearing 01. A trapezoidal groove 1221 is provided on the second connecting portion 122. A detachable adjusting sleeve 2 is provided in the trapezoidal groove 1221. By replacing adjusting sleeves 2 of different specifications, different positions of mounting holes are provided on the adjusting sleeves 2 of different specifications to adapt to pitch bearings 01 of different specifications.

[0068] As a preferred embodiment, the adjusting sleeve 2 is fixed to the trapezoidal groove 1221 through a pressing plate 10 and screws.

[0069] It should be noted that when installing the adjusting sleeve 2, first install the adjusting sleeve 2 in the trapezoidal groove 1221, then press the pressing plate 10 on the adjusting sleeve 2, and fix and tighten it with screws.

[0070] In the above situation, a transverse adjustment hole group 1111 parallel to the slide rail 3 is provided on the U-shaped structure 111, and a longitudinal adjustment hole group 1211 perpendicular to the slide rail 3 is provided on the first connecting portion 121. The transverse adjustment hole group 1111 and the longitudinal adjustment hole group 1211 are connected through adjustment bolts.

[0071] It can be understood that by providing the transverse adjustment hole group 1111, the transverse position of the first connecting portion 121 and the U-shaped structure 111 is adjusted. By providing the longitudinal adjustment hole group 1211, the longitudinal position of the first connecting portion 121 and the U-shaped structure 111 is adjusted. When the relative position of the first connecting portion 121 and the U-shaped structure 111 is adjusted, it is locked through the adjustment bolts. In practical applications, through the cooperation of the transverse adjustment hole group 1111, the longitudinal adjustment hole group 1211 and the adjustment bolts, the relative position of the first connecting portion 121 and the U-shaped structure 111 is effectively adjusted.

[0072] In the above embodiment, any group of the transverse adjustment hole group 1111 includes two first adjustment holes, and any group of the longitudinal adjustment hole group 1211 includes two second adjustment holes. The first adjustment holes and the second adjustment holes are arranged in one-to-one correspondence. Both the first adjustment holes and the second adjustment holes are long strip-shaped waist-shaped holes.

[0073] It should be noted that this hoisting tooling can be adapted to the installation of various pitch bearings 01. During installation, the circumferential installation adjustment of the pitch bearing 01 can be carried out through the waist-shaped hole and adjusting bolts between the U-shaped structure 111 and the first connecting part 121. The circumferential adaptation adjustment of the pitch bearing 01 is carried out by replacing different adjusting sleeves 2 and installation bolt pairs. After the adjustment is completed, the pressure plate 10 and screws are used for limiting to prevent the adjusting sleeve 2 from falling off.

[0074] The installation angle adjustment of the pitch bearing 01 is realized by using the adjustment of the lead screw, slider 4 and servo motor 81. Specifically, the servo motor 81 and the reducer 82 drive the lead screw, so that the slider 4 moves left and right along the slide rail 3 to realize the angle adjustment. During the adjustment process, personnel can observe through the scale 31 on the side of the slide rail 3 to make the slider 4 move to a rough position, and then carry out fine adjustment. The angle sensor 9 on the slider 4 feeds back a signal to confirm whether it is adjusted to the set position. If the set angle is reached, the electromagnetic brake locks.

[0075] In practical applications, first input a start signal through the control panel of the controller, set the working angle for installing the pitch bearing 01, install the pitch bearing 01 through the hoisting tooling. At the same time, the angle sensor 9 can continuously monitor the change in the angle between the center of gravity of the pitch bearing 01 and the end face of the pitch bearing 01, and send the monitored angle signal of the center of gravity deflection of the pitch bearing 01 to the controller. The controller judges the difference between this angle signal and the actual working angle of the installed pitch bearing 01. When the angle of the pitch bearing 01 continuously monitored by the angle sensor 9 is equal to the working angle as Figure 7 shown, the controller controls the servo motor 81 to stop running.

[0076] Please refer to Figure 8 , when the angle A of the pitch bearing 01 continuously monitored by the angle sensor 9 is greater than the working angle, the controller controls the servo motor 81 to run to drive the lead screw to rotate forward until the angle A of the pitch bearing 01 continuously monitored by the angle sensor 9 is equal to the working angle, and then controls the servo motor 81 to stop running, completing the adjustment of the installation angle of the pitch bearing 01.

[0077] When the angle A of the pitch bearing 01 continuously monitored by the angle sensor 9 is less than the working angle, the controller controls the servo motor 81 to run to drive the lead screw to rotate in the reverse direction until the angle A of the pitch bearing 01 continuously monitored by the angle sensor 9 is equal to the working angle, and then controls the servo motor 81 to stop running, completing the adjustment of the installation angle of the pitch bearing 01.

[0078] In summary, the pitch bearing hoisting tooling provided by the present utility model adopts a modular design, ensuring that pitch bearings 01 of different specifications and models can be adapted by simply replacing the adjustment sleeve 2, thereby enhancing the versatility and flexibility of the hoisting tooling. This tooling can install pitch bearings 01 of various sizes, and adjust the installation angle of the pitch bearing 01 through the cooperation of the controller, angle sensor 9, servo motor 81, reducer 82, ball screw assembly 84, slider 4 and slide rail 3, so as to install the pitch bearing 01 more precisely. The coupling surface interface of the hoisting tooling is realized by replacing different adjustment sleeves 2 and installation bolt pairs.

[0079] The pitch bearing hoisting tooling provided by the present utility model is an efficient, flexible and low-cost-optimized pitch bearing hoisting tooling, which is convenient for the mainframe manufacturer to improve the overall machine assembly efficiency, save installation man-hours and tooling costs, and ensure the bearing assembly quality. It can be used for the assembly of pitch bearings 01 in current wind turbine generators, mainly solving the problem of universal installation of pitch bearings 01 with different models, different diameters and different pitch circles, and can realize attitude adjustment and center of gravity compensation actions at different installation angles, covering all existing pitch bearing 01 assemblies in all directions, reducing installation costs and improving the assembly quality of pitch bearings 01.
