[0041] The present application provides an adjustment tool for adjusting the position of a suspension point and an adjustment method thereof. The adjustment tool for adjusting the position of a suspension point and an adjustment method thereof of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0042] The present application provides an adjustment tool for adjusting the position of a lifting point. The adjustment tool includes a connector for connecting a lifting object, a connecting shaft for connecting a lifting device, and an adjustment member. The connecting shaft is movably arranged in the connector along the axial direction of the connecting shaft. The adjustment member is sleeved on the connecting shaft, and the adjustment member is movably connected to the connector; the adjustment member moves relative to the connecting member, driving the connecting shaft to move relative to the connecting member, so as to adjust the position of the lifting point at the connection between the lifting device and the lifting object. The lifting object is connected to the lifting object through the connecting member, the lifting device is connected to the connecting shaft, and the lifting device is movably connected to the connecting member through the adjustment member. When the adjustment member moves relative to the connecting member, the connecting shaft is driven to move relative to the connecting member to adjust the position of the lifting point at the connection between the lifting device and the lifting object, so that the lifting point at the connection between the connecting shaft and the lifting device and the center of gravity of the lifting object are on the same vertical line, thereby reducing the difficulty of assembling, replacing or repairing the lifting object.

[0043] In this embodiment, the adjustment tool is applied to a wind turbine. The hoisted object is a reducer (hereinafter, all hoisted objects are reducers), and this application uses a reducer as an example for explanation. In some other embodiments, the hoisted object may also be other objects with larger volume and / or weight. This is not limited in this application.

[0044] Figure 1 It is a structural schematic diagram of an embodiment of the present application in which the adjusting tool 10 is assembled with the hoisting object (reducer 20) and the pulley assembly 30 of the hoisting equipment. Figure 2 Shown Figure 1 The structure diagram shown is a front view of the assembly of the adjusting tool 10, the hoisting object (reducer 20), and the pulley assembly 30 of the hoisting equipment. Figure 3 Shown Figure 1 The structure diagram of the adjustment tool 10, the hoisting object (reducer 20), and the pulley assembly 30 of the hoisting equipment is shown in a side view. Figure 4 Shown Figure 3 The cross-sectional view of the adjustment tool 10 assembled with the hoisted object (reducer 20) and the pulley assembly 30 of the hoisting equipment is shown. Figures 1 to 4 As shown, the adjusting tool 10 is applied to a wind turbine. The adjusting tool 10 is used to connect the reducer 20 and the lifting device on one hand, and to adjust the position of the lifting point where the lifting device (not shown) is connected to the reducer 20 on the other hand.

[0045] Specifically, the adjusting tool 10 includes a connecting piece 101, a connecting shaft 102 and an adjusting piece 103. The connecting piece 101 is used to connect the reducer 20. The connecting shaft 102 is used to connect the lifting equipment. The connecting shaft 102 is movably arranged in the connecting piece 101 along the axial direction of the connecting shaft 102. The axial direction of the connecting shaft 102 is the same as the axial direction of the reducer 20. Figure 3The axial direction A of the reducer 20 is used to represent the axial direction of the connecting shaft 102. The adjusting member 103 is sleeved on the connecting shaft 102. The adjusting member 103 is movably connected to the connecting member 101. When the lifting equipment lifts the reducer 20, the adjusting member 103 is operated to move relative to the connecting member 101, so as to drive the connecting shaft 102 to move relative to the connecting member 101, and adjust the position of the lifting point where the lifting equipment is connected to the reducer 20, so as to adjust the angle between the axis of the reducer 20 and the axis of the main shaft of the wind turbine (not shown), so that the lifting point where the connecting shaft 102 is connected to the lifting equipment and the center of gravity of the reducer 20 are on the same vertical line.

[0046] According to the installation requirements, the reducer 20 is coaxially assembled with the main shaft of the wind turbine. When hoisting the reducer 20, the center of gravity of the reducer 20 is kept unchanged, and the position of the hanging point where the connecting shaft 102 is connected to the lifting equipment is fine-tuned (for example, the hanging point position is adjusted to move forward and backward along the axial direction of the reducer 20), so that the axis of the reducer is adjusted to the required angle (for example, the angle is to keep the axis of the reducer 20 and the axis of the main shaft of the wind turbine (not shown) on the same axis), so as to keep the hanging point position and the center of gravity of the reducer 20 on the same vertical line, avoid the reducer 20 from rotating around the hanging point of the lifting equipment, thereby avoiding the axis of the reducer 20 from deviating from the axis of the main shaft of the wind turbine, and thus facilitating the assembly, replacement or maintenance of the reducer 20.

[0047] Due to the large size and weight of the reducer 20, when the reducer 20 rotates around the lifting point of the lifting device without changing the position of the lifting point where the reducer 20 is connected to the lifting device, if the adjustment tool 10 is not set, the reducer 20 and / or the lifting device are adjusted to make the lifting point where the lifting device is connected and the center of gravity of the reducer 20 on the same vertical line.

[0048] During this adjustment process, the adjustment range may be relatively large, which increases the difficulty of adjustment and thus affects the adjustment efficiency. By setting the above-mentioned adjustment tool 10, the operator only needs to operate the adjustment tool 10 to keep the center of gravity of the reducer 20 unchanged, and the position of the lifting point of the lifting equipment changes with the movement of the connecting shaft 102, thereby changing the angle between the axis of the reducer 20 and the axis of the main shaft of the wind turbine. This can be achieved by fine-tuning the position of the lifting point, which can reduce the difficulty of adjustment, improve the adjustment efficiency, and also save manpower.

[0049] It should be noted that the adjusting member 103 is adjusted by the operator using installation or removal tools (for example, a wrench), and other tools may also be used. In the present embodiment, the lifting device is connected to the adjusting fixture 10 via a pulley assembly 30. Only the pulley assembly 30 is shown in the accompanying drawings. The lifting point position where the lifting device is connected to the reducer 20 is the lifting point position where the pulley assembly 30 is connected to the reducer 20, that is, in the present embodiment, the lifting point position is the lifting point position where the connecting shaft 102 is connected to the pulley assembly 30. In some other embodiments, the lifting device may also be connected to the adjusting fixture 10 via other components. This is not limited in the present application.

[0050] In some embodiments, the connector 101 is provided with a first through hole 104 and a second through hole 105 (eg, Figure 4 As shown in FIG. 1 , one of the first through hole 104 and the second through hole 105 is a first threaded hole. Figure 4 In the embodiment shown, the first through hole 104 is a first threaded hole, and the first threaded hole is located on the side of the reducer 20 away from the mounting opening 21 of the reducer 20. The mounting opening 21 is used to mount the main shaft of the wind turbine (such as Figure 4 As shown). The adjusting member 103 is inserted into the first threaded hole, and the outer wall of the adjusting member 103 is provided with a first thread matching the first threaded hole. The adjusting member 103 is assembled to the connecting member 101 by matching the first thread with the first threaded hole. The adjusting member 103 and the connecting member 101 are threadedly connected to ensure the smooth movement. The threaded connection is a detachable fixed connection method, which can be easily assembled and disassembled, and the threaded connection structure is simple and the connection is reliable. One end of the adjusting member 103 is the adjustment end, and the adjustment end is arranged on the side away from the mounting port 21 of the reducer 20, which is convenient for the operator to operate. In addition, the second through hole 105 is set as an ordinary through hole, and the connecting member 101 and the connecting shaft 102 are in a shaft-hole matching manner. The connecting shaft 102 moves along the axial direction of the connecting shaft 102, so that the connecting shaft 102 can move more flexibly in the through hole. When hoisting the reducer 20 , the adjusting member 103 rotates relative to the connecting member 101 , driving the connecting shaft 102 to move relative to the connecting member 101 along the axial direction of the connecting shaft 102 , thereby adjusting the position of the lifting point where the lifting equipment is connected to the reducer 20 .

[0051] In some embodiments, the connecting member 101 includes two ears 106 spaced apart in the axial direction of the connecting shaft 102, and the connecting shaft 102 is inserted into the two ears 106 (eg, Figure 1As shown). The adjusting member 103 is sleeved on one of the two lifting ears 106. The lifting point where the connecting shaft 102 is connected to the lifting device is located between the two lifting ears 106 in the axial direction of the connecting shaft 102, that is, the pulley assembly 30 is assembled on the connecting shaft 102 and is located between the two lifting ears 106. In this way, the lifting point where the connecting shaft 102 is connected to the lifting device is balanced with the contact point between the connecting member 101 and the connecting shaft 102, making the adjustment process smoother. Figure 4 In the illustrated embodiment, the adjusting member 103 is inserted into a lifting ear 106 located on the side of the reducer 20 away from the mounting opening 21 of the reducer 20, and the adjusting member 103 is threadedly connected to the lifting ear 106. In some embodiments, the two lifting ears 106 are integrally provided with the reducer 20, and the fixing stability of the connecting member 101 fixed to the reducer 20 is better, the service life is longer, and unnecessary losses caused by unstable fixing are avoided.

[0052] When hoisting the reducer 20, first connect the connector 101 to the reducer 20. In this embodiment, the connector 101 is a lifting lug 106 integrally formed with the reducer 20. Therefore, this step can be omitted. In other embodiments, when the connector 101 and the reducer 20 are separately provided, it can be performed as the first step. It is not limited in this application. Then, the pulley assembly 30 of the lifting equipment and the connector 101 are connected by adjusting the tooling 10. Then, the speed reducer 20 is lifted by the lifting equipment, and the deviation between the axis of the speed reducer 20 after lifting and the axis of the main shaft of the wind turbine is observed. The adjusting member 103 on the adjusting tool 10 is rotated. Since the adjusting member 103 and the connecting member 101 are threadedly connected, the adjusting member 103 will move left or right along the axial direction of the connecting shaft 102 relative to the connecting member 101, driving the connecting shaft 102 to move left or right together. At this time, the hanging point position where the connecting shaft 102 and the speed reducer 20 are connected will move left or right with the connecting shaft 102. At this time, the center of gravity of the speed reducer 20 will rotate around the center point of the hanging point position, so that the axis of the speed reducer 20 can be adjusted to the required angle. This can reduce the difficulty of adjustment and save manpower.

[0053] Figure 5 It is a structural schematic diagram of an embodiment of assembling the adjusting tool 10 of the present application with the pulley assembly 30 of the lifting equipment. Figure 6 Shown Figure 5 The structure diagram of the adjustment tool 10 and the pulley assembly 30 of the lifting equipment is shown in a side view. Figure 7 Shown Figure 5 The structure diagram shown is a front view of the assembly of the adjusting tool 10 and the pulley assembly 30 of the lifting equipment. Figure 8 Shown Figure 5 The adjustment tool 10 is shown in a cross-sectional view assembled with the pulley assembly 30 of the lifting equipment. Figures 1 to 8As shown, the adjusting member 103 and the connecting shaft 102 are separately arranged.

[0054] In some embodiments, the connecting shaft 102 includes a shaft body 107 that passes through the connecting member 101 and a connecting bearing 108 that is sleeved on the shaft body 107. The connecting bearing 108 is sleeved on the outer side of the shaft body 107. The lifting device (for example, the pulley assembly 30) is connected to the connecting bearing 108. That is, the position where the connecting bearing 108 is located is the position of the hanging point where the connecting shaft 102 is connected to the lifting device. The adjusting member 103 is sleeved on one end of the shaft body 107 to partially cover the shaft body 107. The adjusting end is used to be operated by the operator, and the end opposite to the adjusting end abuts against the connecting bearing 108 in the axial direction of the connecting shaft 102. Such a setting plays a role in positioning the connecting bearing 108, ensuring that when the adjusting member 103 drives the shaft body 107 and the connecting bearing 108 to move, the shaft body 107 and the connecting bearing 108 can move synchronously, so that the hanging point position can be adjusted synchronously.

[0055] When hoisting the reducer 20, the adjusting member 103 rotates relative to the connecting member 101, driving the shaft 107 and the connecting bearing 108 to move relative to the connecting member 101 along the axial direction of the connecting shaft 102, so as to adjust the position of the lifting point where the lifting equipment is connected to the reducer 20. During this adjustment process, the adjusting member 103 rotates relative to the connecting member 101 along the axial direction of the connecting shaft 102, and moves along the axial direction of the connecting shaft 102. After the shaft 107 is driven by the adjusting member 103, it rotates relative to the connecting member 101 along the axial direction of the connecting shaft 102, and moves along the axial direction of the connecting shaft 102. After the connecting bearing 108 is driven by the adjusting member 103, it moves synchronously relative to the shaft 107 along the axial direction of the connecting shaft 102. In this way, the position of the hanging point where the connecting shaft 102 is connected to the lifting equipment is adjusted so that the axis of the reducer is adjusted to the required angle, thereby keeping the hanging point position and the center of gravity of the reducer 20 on the same vertical line, avoiding the reducer 20 from rotating around the hanging point of the lifting equipment, thereby avoiding the axis of the reducer 20 from deviating from the main axis of the wind turbine main shaft, and facilitating the assembly, replacement or maintenance of the reducer 20.

[0056] In this embodiment, the shaft body 107, the connecting bearing 108 and the adjusting member 103 are separately arranged. The shaft body 107 is a conical structure, including a large end and a small end. Among them, the adjusting member 103 is sleeved on the small end of the shaft body 107, and the large end of the shaft body 107 is matched with the shaft hole of the connecting member 101. In some embodiments, the shaft body 107 includes a first shaft end 109 and a second shaft end 110, and the radial dimension of the first shaft end 109 is smaller than the radial dimension of the second shaft end 110. In this embodiment, since the aperture sizes of the first through hole 104 and the second through hole 105 are consistent, in order to ensure that the adjusting member 103 can be assembled on the first shaft end 109, the cross-sectional area of ​​the first shaft end 109 is set smaller than the cross-sectional area of ​​the second shaft end 110, so that there is space between the first shaft end 109 and the first through hole 104, the adjusting member 103 is sleeved on the first shaft end 109 to adapt to the first through hole 104 on the connecting member 101, ensuring that the threaded connection between the adjusting member 103 and the first through hole 104 is more adapted, making the structure more compact.

[0057] In some embodiments, the shaft body 107 is provided with a first step 111 and a second step 112 along the axial direction of the connecting shaft 102, and the first step 111 is closer to the first shaft end 109 (eg, Figure 8 As shown). The adjusting member 103 is arranged at the first shaft end 109, and abuts against the first step 111 in the axial direction of the connecting shaft 102, and the connecting bearing 108 abuts between the adjusting member 103 and the second step 112. Since the adjusting end of the adjusting member 103 is threadedly connected to the first through hole 104, that is, the adjusting end is fixedly connected to the connecting member 101, and the other end of the adjusting member 103 opposite to the adjusting end abuts against one end of the connecting bearing 108 in the axial direction of the connecting shaft 102, and the other end of the connecting bearing 108 abuts against the second step 112, the connecting bearing 108 is fixed to the shaft body 107 in this way. In this way, the connecting bearing 108 and the shaft body 107 are ensured to move synchronously, so that the movement stability is better.

[0058] In some embodiments, the adjusting member 103 includes a cylindrical structure. The cylindrical structure is wrapped around the outside of the first shaft end 109. The connecting shaft 102 also includes a first fixing member 113, and the adjusting member 103 is assembled to the first shaft end 109 by matching the first fixing member 113 with the first shaft end 109. In some embodiments, the first fixing member 113 can be a bolt or a latch, etc., which is not limited in the present application. The adjusting member 103 is fixed to the first shaft end 109 by the first fixing member 113 to ensure that the end of the adjusting member 103 opposite to the adjusting end is in contact with the first step 111 and the connecting bearing 108. This arrangement ensures that the connecting bearing 108 and the shaft body 107 move synchronously.

[0059] In some embodiments, the first shaft end 109 is provided with a limiting groove 114. The connecting shaft 102 further includes a shaft end retaining ring 115, which is sleeved in the limiting groove 114 and clamped between the first fixing member 113 and the adjusting member 103. The shaft end retaining ring 115 is limited in the limiting groove 114 to fix the adjusting member 103. The shaft end retaining ring 115 can be used as a gasket between the first fixing member 113 and the adjusting member 103, so that the contact area between the first fixing member 113 and the adjusting member 103 is larger, and the force between the first fixing member 113 and the adjusting member 103 is ensured to be uniform.

[0060] In some embodiments, the adjusting member 103 includes a sleeve 116 and an adjusting boss 117 protruding from the surface of the sleeve 116. The adjusting boss 117 is compatible with the installation or removal tool used by the operator. The radial dimension of the adjusting boss 117 is at least larger than the radial dimension of the shaft end retaining ring 115. When the operator operates the adjusting member 103, the installation or removal tool is sleeved on the edge of the adjusting boss 117 and is in full contact with the adjusting boss 117. The radial dimension of the adjusting boss 117 is set to be at least larger than the radial dimension of the shaft end retaining ring 115 to avoid being affected by the edge of the shaft end retaining ring 115 when operating the adjusting boss 117, thereby affecting the installation efficiency.

[0061] In some embodiments, the thickness of the sleeve 116 along the radial direction of the connecting shaft 102 is greater than the height of the first step 111 along the radial direction of the connecting shaft 102. The radial direction of the connecting shaft 102 is the same as the radial direction of the reducer 20. The thickness of the sleeve 116 is set to be slightly higher than the first step 11 to ensure that one end of the sleeve 116 abuts against the first step 111 and can partially or completely abut against the connecting bearing 108, in order to fix the connecting bearing 108 and prevent the connecting bearing 108 from being misaligned, thereby avoiding changes in the position of the hanging point. In some embodiments, the sleeve 116 and the adjusting boss 117 are integrally arranged. The integral structure is simple and compact, and reduces the number of components, making assembly easier.

[0062] When assembling the adjusting tool 10, firstly, one end of the shaft body 107 is sleeved on the second through hole 105, and then the connecting bearing 108 is sleeved on the shaft body 107 and abutted against the second step 112, and then the adjusting member 103 is sleeved on the first shaft end 109 and threadedly connected to the first through hole 104, and then assembled in the limiting groove 114 using the shaft end retaining ring 115, and finally the adjusting member 103 is fixed to the first shaft end 109 using the first fixing member 113.

[0063] In some other embodiments, the connecting shaft includes a shaft body passing through the connecting member and a connecting bearing sleeved on the shaft body, and the adjusting member and the shaft body are integrally arranged as an adjusting shaft body. The lifting equipment is connected to the connecting bearing, and the connecting bearing is provided with a second threaded hole. The adjusting shaft body is passed through the second threaded hole, and the outer wall of the adjusting shaft body is provided with a second thread matching the second threaded hole. The connecting bearing is assembled on the adjusting shaft body through the matching of the second thread and the second threaded hole, and the adjusting shaft body rotates relative to the connecting bearing and the connecting member, driving the connecting bearing to move relative to the connecting member along the axial direction of the connecting shaft. The two ends of the adjusting shaft body are fixed to the connecting member by fixing members (for example, bolts or latches, etc.). When adjusting the rotation of the adjusting shaft body, the adjusting shaft body is relative to the connecting bearing and the connecting member.

[0064] During the adjustment process, for the connecting piece, the adjusting shaft body rotates relative to the connecting piece along the axial direction of the connecting shaft, but does not move relatively in the axial direction of the connecting shaft. For the connecting bearing, the adjusting shaft body rotates relative to the connecting bearing along the axial direction of the connecting shaft, and at this time the connecting bearing also rotates relative to the adjusting bearing along the axial direction of the connecting shaft, and also moves along the axial direction of the connecting shaft, so as to adjust the position of the hanging point where the adjusting shaft body is connected with the lifting device, so as to adjust the angle between the axis of the reducer and the axis of the main shaft of the wind turbine, so that the hanging point where the connecting shaft and the lifting device are connected is on the same vertical line as the center of gravity of the reducer. By setting an integrated structure of the adjusting shaft body to cooperate with the reducer and the lifting device, the number of components is simplified, the difficulty of matching between components is reduced, and the assembly efficiency is improved.

[0065] In some other embodiments, the connecting member is separately provided from the reducer. The connecting member 101 is an independent connecting member. The adjustment tool further includes a second fixing member, through which the connecting member is fixedly connected to the reducer. By providing the second fixing member, the disassembly and assembly of the adjustment tool are facilitated. The second fixing member may be a bolt, a latch, etc., which is not limited in this application.

[0066] Fig. 9 FIG. 1 is a flow chart showing the steps of an embodiment of the adjustment method of the present application. Fig. 9 As shown in FIG. 1 , the adjustment method for adjusting the position of the suspension point is applied to the adjustment tool for adjusting the position of the suspension point. The adjustment tool can be the above Figures 1 to 8 The adjusting tool in the embodiment shown. The adjusting method comprises step S1.

[0067] Step S1, adjust the adjusting member to drive the connecting shaft to move relative to the connecting member to adjust the position of the lifting point where the lifting device is connected to the lifting object. By using the above adjustment method, it is ensured that the lifting point where the connecting shaft is connected to the lifting device and the center of gravity of the lifting object are on the same vertical line, reducing the difficulty of assembling, replacing or repairing the lifting object.

[0068] In this embodiment, the adjustment method is applied to a wind turbine. The hoisted object is a reducer, and this adjustment method is explained by taking the adjustment of the reducer as an example. By adjusting the adjusting member, the connecting shaft is driven to move relative to the connection to adjust the position of the hanging point where the lifting device is connected to the reducer, so as to adjust the angle between the axis of the reducer and the axis of the main shaft of the wind turbine. By adopting the above adjustment method, the center of gravity of the reducer is kept unchanged, and the angle between the axis of the reducer and the axis of the main shaft of the wind turbine is adjusted by fine-tuning the position of the hanging point where the reducer is connected to the lifting device, so as to make the center of gravity of the hanging point and the reducer be located on the same vertical line, so as to avoid the reducer from rotating around the hanging point of the lifting device, thereby avoiding the deviation of the axis of the reducer from the main axis of the wind turbine, thereby facilitating the assembly, replacement or maintenance of the reducer.

[0069] Fig.10 Shown Fig. 9 FIG. 1 is a flow chart of an embodiment of step S1 of the adjustment method shown in FIG. Fig.10 As shown, step S1 includes step S11. Among them,

[0070] Step S11, adjust the adjusting member to rotate relative to the connecting member, and drive the connecting shaft to move relative to the connecting member along the axial direction of the connecting shaft. With the above adjustment method, the operator only needs to use the installation or removal tool to rotate the adjusting member to drive the connecting shaft to move along the axial direction of the connecting shaft. This can be achieved by fine-tuning the position of the hanging point, which can reduce the difficulty of adjustment, improve the adjustment efficiency, and also save manpower.

[0071] Fig.11 Shown Fig. 9 FIG. 1 is a flow chart of another embodiment of step S1 of the adjustment method shown in FIG. Fig.11 As shown, step S1 includes step S12. Among them,

[0072] Step S12, adjust the adjusting member to rotate relative to the connecting member, and drive the shaft body and the connecting bearing to move relative to the connecting member along the axial direction of the connecting shaft. With the above adjustment method, the operator only needs to use the installation or removal tool to rotate the adjusting member to drive the shaft body and the connecting bearing to move along the axial direction of the connecting shaft, so as to adjust the position of the lifting point where the connecting shaft 102 is connected to the lifting device. This can reduce the difficulty of adjustment and improve the efficiency of adjustment.

[0073] Fig.12 Said Fig. 9 FIG. 1 is a flow chart of another embodiment of step S1 of the adjustment method shown in FIG. Fig.12 As shown, step S1 includes step S13. Among them,

[0074] Step S13, adjust the adjustment shaft body to rotate relative to the connecting bearing and the connecting member, and drive the connecting bearing to move relative to the connecting member along the axial direction of the connecting shaft. Using the above adjustment method, for the connecting member, the adjustment shaft body rotates relative to the connecting member along the axial direction of the connecting shaft, but does not move relatively in the axial direction of the connecting shaft. For the connecting bearing, the adjustment shaft body rotates relative to the connecting bearing along the axial direction of the connecting shaft, and at this time the connecting bearing also rotates relative to the adjustment bearing along the axial direction of the connecting shaft, and also moves along the axial direction of the connecting shaft, so as to adjust the position of the hanging point where the adjustment shaft body is connected to the lifting device, so as to adjust the axis of the reducer to the desired angle, so that the hanging point where the connecting shaft is connected to the lifting device and the center of gravity of the reducer are on the same vertical line.

[0075] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
