Description

Technical field:

[0002] The invention relates to the technical field of wind power generation, and in particular to a positioning arm for a blade web positioning tool. Background technology:

[0004] With the development of wind power generation technology, higher and higher requirements are put forward for the strength and assembly efficiency of wind turbine blades. In the manufacturing process of wind turbine blades, each blade needs to be installed with a web to improve the force strength of the blade, and the assembly of the web to the blade requires relevant positioning tooling to assist in the installation. The positioning tooling uses a positioning arm for positioning. The design of the positioning arm is very critical and directly determines whether the positioning of the entire tooling is convenient and accurate. Summary of the invention:

[0006] To this end, it would be advantageous for the present invention to provide a positioning arm for a blade web positioning tooling that is easy to use, easy to position and adjust, and accurate.

[0007] To achieve the above object, the present invention provides a positioning arm for a blade web positioning tool, which is installed in pairs on the main steel frame of the blade web positioning tool, wherein the positioning arm includes

[0008] A boom steel frame and a retractable positioning arm, wherein the boom steel frame is rotatably mounted on the main steel frame between an extended support position and a folded storage position, the retractable positioning arm comprises a positioning jacking device, a three-way adjustable leg seat and a boom base, the positioning jacking device is mounted on the boom steel frame and has a retractable top rod that can move between a downwardly extended position and an upwardly retracted position, the three-way adjustable leg seat comprises a jacking docking base located at its upper end for receiving and supporting the retractable top rod.

[0009] In the present invention, since the positioning jacking device is installed on the boom steel frame and its retractable push rod is received on the jacking docking base of the three-way adjustable leg seat, when the retractable push rod moves from the upward retracted position to the downward extended position, the retractable positioning arm becomes longer (i.e., it becomes higher relative to the ground), so that the main steel frame of the entire tooling can be moved upward; when the retractable push rod moves from the downward extended position to the upward retracted position, the retractable positioning arm becomes shorter (i.e., it becomes shorter relative to the ground), so that the main steel frame of the entire tooling can be moved downward; through this upward and downward adjustment, the blade web positioning tooling using the positioning boom can position the blade web at an appropriate height; and the length of the retractable positioning arm is adjusted by the positioning jacking device, which has good stability, high strength and impact resistance. In addition, the setting of the three-way adjustable leg seat enables the position of the jacking docking base to be adjusted in three directions: front and back, up and down, and left and right, so as to accurately receive the retractable push rod. In addition, the setting of the boom base allows the positioning boom to be fixed on both sides of the blade production mold through it.

[0010] Furthermore, the positioning and lifting device includes an electric cylinder mounting seat fixed on the boom steel frame, an electric cylinder with a retractable top rod, and a servo motor driving the electric cylinder, wherein a guide force-bearing seat is also installed on the electric cylinder mounting seat, and the retractable top rod is installed through the guide force-bearing seat.

[0011] Through the above structural arrangement, the operation of lengthening and shortening the telescopic positioning arm is very convenient, and the use is safe and reliable.

[0012] Furthermore, the three-way adjustable leg base includes, from top to bottom, a lifting and docking base, a mounting base, a connecting base and a connecting leg, wherein the lifting and docking base is adjustably mounted on the mounting base front and back, the mounting base is adjustably mounted on the connecting base up and down, the connecting base is adjustably mounted on the connecting leg left and right, and the connecting leg is fixed on the boom base.

[0013] Through the above-mentioned structural arrangement, the position of the lifting docking base can be adjusted in three directions: front and back, up and down, and left and right.

[0014] Furthermore, the mounting base is provided with a front and rear adjustment waist-shaped hole, and the jacking docking base is mounted on the mounting base in a front and rear adjustable manner with the aid of bolts that pass through the front and rear adjustment waist-shaped hole and are tightened thereon; the mounting base is also provided with a height adjustment bolt, and the connecting base is provided with a bolt receiving seat that is adapted to the height adjustment bolt; the connecting leg is provided with a left and right adjustment waist-shaped hole, and the connecting base is mounted on the connecting leg in a left and right adjustable manner with the aid of bolts that pass through the left and right adjustment waist-shaped hole and are tightened thereon.

[0015] Through the above structural setting, the position of the lifting docking base can be adjusted very conveniently from front to back, up to down, left to right by adjusting the position of the bolt, so as to better connect the top rod.

[0016] Furthermore, the three-way adjustable leg base also includes a height limiting device, which includes a limiting bolt and a limiting through hole located on the connecting base, the limiting through hole is arranged to extend horizontally and be connected to the bolt receiving seat, and the limiting bolt is suitable for passing through the limiting through hole to abut the height adjustment bolt in the radial direction.

[0017] Through the above-mentioned structural setting, the height adjustment and height stability of the height adjustment bolt can be achieved by loosening and tightening the limit bolt.

[0018] Furthermore, the height adjustment bolt is also provided with an adjusting nut adapted thereto, and the adjusting nut is located above the mounting base; a nut accommodating cavity is provided at the bottom of the jacking docking base corresponding to the adjusting nut.

[0019] Through this structural arrangement, when the height adjustment bolt is adjusted to a certain height position, it can also be tightened by adjusting the nut, thereby further ensuring the position retention of the height adjustment bolt.

[0020] Furthermore, a positioning pin is installed at the end of the telescopic top rod, and a positioning pin seat adapted to the positioning pin is arranged on the jacking docking base.

[0021] Through this structural arrangement, the coordinated positioning of the telescopic jack and the lifting docking base is made more reliable.

[0022] Furthermore, the upper arm base is constructed in the form of a tripod and has a mounting base plate, and the mounting base plate is provided with left and right adjustment waist-shaped holes.

[0023] Through the above structure, the supporting capacity of the boom base is enhanced. At the same time, due to the setting of the left and right adjustment waist-shaped holes thereon, the positioning of the boom base on both sides of the blade web production mold becomes adjustable, making the positioning of the entire positioning boom flexible and adjustable.

[0024] Furthermore, the boom steel frame is rotatably fixed to the main steel frame via a rotating mounting assembly on its inner side close to the main steel frame. The rotating mounting assembly includes an upper rotating mounting seat and a lower rotating mounting seat fixed to the main steel frame, and a long rotating shaft fixed to the boom steel frame. The long rotating shaft is rotatably mounted at its upper and lower ends in the upper rotating mounting seat and the lower rotating mounting seat respectively.

[0025] This structural arrangement makes it easy and smooth for the boom steel frame for positioning the boom to switch between the unfolded support position and the folded storage position.

[0026] Furthermore, the positioning arm for the blade belly positioning tooling also includes an expansion positioning device for positioning the arm steel frame in the expansion support position, and the expansion positioning device includes a triangular bracket installed on the main steel frame, a spring pin mounting seat installed on the triangular bracket, an expansion positioning seat installed on the arm steel frame, and a spring pin fixing the expansion positioning seat and the spring pin mounting seat together.

[0027] By means of the above structural arrangement, when the positioning arm is in the unfolded support position, the arm steel frame can be fixed relative to the main steel frame by means of the spring pin, so that the positioning arm can be stably positioned at this position as a support for the entire tooling. These and other aspects of the present invention will be more clearly described by referring to the embodiments described below. Description of the drawings:

[0040] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, according to a specific embodiment of the present invention, the positioning arm 3 for the blade web positioning tool is installed in pairs on the main steel frame 1 of the blade web positioning tool 100. For the sake of clarity of the figure, Figure 2 Only a pair of positioning arms 3 are shown on the front side, while the suction cup arms 5 of the blade positioning web tooling 100 are Figure 1They are not shown in pairs, and only the suction cup arm 5 located on the right side of the main steel frame 1 is shown.

[0042] like Figure 1 and Figure 2 As shown, and refer to Figure 3 and Figure 4 Each positioning boom 3 includes a boom steel frame 30 and a telescopic positioning arm 32. The boom steel frame 30 is configured to be suitable for being in the unfolded support position (see Figure 1 The telescopic positioning arm 32 includes a positioning lifting device 2, a three-way adjustable leg base 34 and a large arm base 36. Figures 2 to 4 As shown, the positioning jacking device 2 is installed on the boom steel frame 30 and has a retractable jack rod 21 that can move between a downward extended position and an upward retracted position. The three-way adjustable leg base 34 includes a jacking docking base 31 located at its upper end to receive and support the retractable jack rod 21.

[0043] In the present invention, since the positioning jacking device 2 is installed on the boom steel frame 30, and its telescopic top rod 21 is received on the jacking docking base 31 of the three-way adjustable leg seat 34, when the telescopic top rod 21 moves from the upward retracted position to the downward extended position, the entire telescopic positioning arm 32 of the positioning boom 3 becomes longer (i.e., becomes higher relative to the ground), and the main steel frame 1 moves upward with the suction cup arm 5; when the telescopic top rod 21 moves from the downward extended position to the upward retracted position, the telescopic positioning arm 32 becomes shorter (i.e., becomes shorter relative to the ground), and the main steel frame 1 moves downward with the suction cup arm 5; through the upward and downward adjustment of the suction cup arm 5, the suction cup arm 5 can adsorb and position the blade web at an appropriate height (not shown); and the length of the telescopic positioning arm 32 is adjusted by the positioning jacking device 2, which has good stability, high strength and impact resistance. In addition, the setting of the three-way adjustable leg seat 34 enables the position of the jacking docking base to be adjusted in three directions: front and back, up and down, and left and right, so as to accurately receive the telescopic top rod. In addition, the arrangement of the upper arm base 36 allows the three-way adjustable leg base 34 to be fixed to both sides of the blade production mold (not shown) through it.

[0044] It should be noted that the upper arm base 36 is constructed in the form of a tripod and is provided with a plurality of left and right adjustment waist-shaped holes 360 for adjusting its installation position on the blade web production mold to meet the position adjustment within the error range.

[0045] like Figure 5 As shown, and refer to Figure 1The positioning and lifting device 2 includes an electric cylinder 20 with a retractable push rod 21, an electric cylinder mounting seat 22 fixed on a large arm steel frame 30, and a servo motor 24 driving the electric cylinder 20.

In addition, in this embodiment, Figure 5 and Figure 6 As shown, the telescopic push rod 21 has a positioning pin 210 at its end, and the lifting docking base 31 is provided with a positioning pin seat 310 adapted to the positioning pin 210. When the positioning arm 3 is in the position as shown in FIG. Figure 3 In the positioning state shown, the positioning pin 210 sits on the positioning pin seat 310 of the lifting docking base 31. Through the above-mentioned structural arrangement, the operation of lengthening and shortening the telescopic positioning arm 32 is very convenient, and the use is safe and reliable.

[0046] like Figure 5 , Figure 6 and Figure 7 As shown, and refer to Figures 1 to 4 The three-way adjustable leg base 34 includes a lifting and docking base 31, a mounting base 33, a connecting base 35 and a connecting leg 37 from top to bottom, wherein the lifting and docking base 31 is adjustably mounted on the mounting base 33 front and back, the mounting base 33 is adjustably mounted on the connecting base 35 up and down, the connecting base 35 is adjustably mounted on the connecting leg 37 left and right, and the connecting leg 37 is fixed on the boom base 36.

[0047] Specifically, Figure 6 As shown, and refer to Figure 5 and Figure 7 In this embodiment, a front-to-back adjustment waist-shaped hole 331 is provided on the mounting base 33, and the lifting docking base 31 is adjustably mounted on the mounting base 33 by means of a bolt (not shown) passing through the front-to-back adjustment waist-shaped hole 331 and tightened thereon; a height adjustment bolt 335 is also provided on the mounting base 33, and a bolt receiving seat 355 adapted to the height adjustment bolt 335 is provided on the connecting base 35; a left-to-right adjustment waist-shaped hole 375 is provided on the connecting leg 37, and the connecting base 35 is adjustably mounted on the connecting leg 37 by means of a bolt 377 passing through the left-to-right adjustment waist-shaped hole 375 and tightened thereon.

[0048] The three-way adjustable leg base 34 also includes a height limiting device, which includes a limiting bolt 337 and a limiting through hole 357 located on the connecting base 35. The limiting through hole 357 is arranged to extend horizontally and communicate with the bolt receiving seat 355. The limiting bolt 337 is suitable for passing through the limiting through hole 357 to abut against the height adjustment bolt 335 in the radial direction. When the height adjustment bolt 335 is adjusted to a certain height, the limiting member 337 passes through the limiting hole 357 and is tightened inwardly so as to abut against the height adjustment bolt 335. It should be noted that a bolt storage seat 332 is also installed at the bottom of the mounting base 33, and the limiting bolt 337 can be stored in the bolt storage seat 332 when it is not working. Through the above-mentioned structural setting, the position of the jacking docking base 31 can be adjusted very conveniently from the front and back, up and down, and left and right directions, and the height adjustment bolt 335 can also be limited by the limiting member 337.

[0049] In addition, if Figure 7 and Figure 8 As shown, in this embodiment, the height adjustment bolt 335 is also provided with an adjustment nut 334 adapted thereto, and the adjustment nut 334 is located above the mounting base 33, and a nut accommodating cavity 314 is provided at the bottom of the jacking docking base 31 corresponding to the adjustment nut 334. With this structural arrangement, when the height adjustment bolt 335 is adjusted to a certain height position, it can also be tightened by the adjustment nut 334, thereby further ensuring the position retention of the height adjustment bolt 335.

[0050] It should be noted that when the positioning arm 3 is used, the arm base 36 of the telescopic positioning arm 32 is first fixed to the ground on both sides of the web mold, and the three directions of the three-way adjustable leg seat 34 are adjusted to meet the composite position requirements. The other parts of the tooling help the telescopic top rod 21 of the positioning jacking device 2 to find a position under the transportation of the crane. At this time, the telescopic top rod 21 is not received on the three-way adjustable leg seat 34. Figure 4 As shown, when the telescopic top rod 21 is aligned with the jacking docking base 31 of the three-way adjustable leg seat 34 and is received therein, the crane lowers the tooling, and at this time, the extension or retraction length of the telescopic top rod 21 of the positioning jacking device 2 is adjusted to adjust the height of the positioning boom 3 to adapt to the size of the web.

[0051] For example Figure 1 As shown, and refer to Figure 2In this embodiment, the boom steel frame 30 is rotatably fixed to the main steel frame 1 via a rotating mounting assembly 4 on its inner side close to the main steel frame 1. The rotating mounting assembly 4 includes an upper rotating mounting seat 40 and a lower rotating mounting seat 42 fixed to the main steel frame 1, and a long rotating shaft 41 fixed to the boom steel frame 30. The long rotating shaft 41 is rotatably mounted in the upper rotating mounting seat 40 and the lower rotating mounting seat 42 at its upper end and lower end, respectively. Through this structural setting, the boom steel frame 30 for positioning the boom 3 becomes easy and smooth to switch between the unfolded support position and the folded storage position. The rotating mounting assembly 4 also includes a bearing and a dust cover (not shown in the figure). The bearing is installed in a bearing mounting hole (not shown in the figure) integrally formed with the upper rotating mounting seat 40 and the lower rotating mounting seat 42, respectively, and is sleeved on the long rotating shaft 41.
