The wind power blade is connected to a power generation main machine hub through a blade root pre-embedded bolt sleeve. The pre-embedded bolt sleeve has an internal thread structure. The pre-embedded bolt sleeve is connected to the power generation main machine hub through a bolt. The pre-embedded bolt sleeve is one of the key stress components of the pre-embedded blade root structure. In the current blade structure design, the form of pre-embedding the bolt sleeve in the layering process is adopted, specifically including: in the blade root production process, first, laying an outer skin, manually assembling and arranging pre-embedded components on the outer skin, the bolt sleeve and the wedge block forming the pre-embedded component. After the arrangement of multiple pre-embedded components is completed, laying an inner skin on the pre-embedded component, and then completing resin pouring in a vacuum pouring manner, and forming the blade root component after the resin is cured.

One flange hole 121 corresponds to the arrangement of one bolt 130 and one bolt sleeve 160. The bolt 130 is connected with the bolt sleeve 160.

[0082] In some implementable manners, in the blade root pre-embedded assembly 100, along the circumferential direction of the flange 120, the bolt sleeve 160 and the first wedge block 140 are arranged alternately.

In the blade root 40 forming process, after the outer skin is laid on the blade root 40 mold, the embedded part 110 can be accurately placed on the outer skin by the blade root embedded assembly 100, so that the embedded part 110 does not need to be placed in the blade root 40 mold one by one by manual operation, which is beneficial to optimize the production rhythm and improve the production efficiency.

[0096] In some implementable manners, referring to Figure 5 As shown, the flange 120 in the blade root embedded assembly 100 is semicircular. The blade root structure formed after the blade root 40 mold is semicircular. Two semicircular blade root structures are used to form a circular blade root 40.

[0097] Referring to Figure 9 to Figure 13 As shown in the drawings, the embodiment of the present application provides a blade root pre-embedded component assembly equipment 200 for wind turbine blades, which comprises a flange fixing device 210, a feeding device 220, a pre-embedded component assembly device 230 and a bolt mounting device 240.

[0098] The flange fixing device 210 comprises a first driving assembly 211, a horizontal support platform 212 and a sliding seat 213. The horizontal support platform 212 comprises an annular horizontal guide rail 214. The axial direction of the annular horizontal guide rail 214 is the same as the vertical direction. The sliding seat 213 is slidably connected to the annular horizontal guide rail 214.

[0099] The sliding seat 213 is used for connecting and fixing a semicircular flange 120. The axial direction of the flange 120 is the same as the vertical direction. The flange 120 comprises flange holes 121. A plurality of flange holes 121 are distributed along the circumference of the flange 120. The first driving assembly 211 is used for driving the sliding seat 213 and the flange 120 to move synchronously along the annular horizontal guide rail 214.

[0100] The feeding device 220 comprises a material conveying assembly 221. The material conveying assembly 221 is used for moving the material to be assembled from a feeding station to an assembly station. The material to be assembled comprises a bolt sleeve 160 and a first wedge-shaped block 140.

[0101] The pre-embedded component assembly device 230 is used for transferring the bolt sleeve 160 or the first wedge-shaped block 140 at the assembly station to above the flange 120, and aligning the bolt sleeve 160 with the flange holes 121 in the vertical direction.

[0102] The bolt mounting device 240 is used for transferring the bolt 130 to below the flange 120, and connecting the bolt 130 with the bolt sleeve 160 through the flange hole 121 in the vertical direction, so as to connect and fix the bolt 130, the bolt sleeve 160 and the flange 120.

[0103] In some implementable manners, the bolt sleeve 160 and the first wedge-shaped block 140 are alternately arranged on the material conveying assembly 221. The pre-embedded component assembly device 230 is used for aligning the bolt sleeve 160 with the first flange hole 121 of the flange 120. The bolt 130 is connected and fixed with the bolt sleeve 160. The pre-embedded component assembly device 230 transfers the first wedge-shaped block 140 to the flange 120, and the first wedge-shaped block 140 is arranged side by side with the bolt sleeve 160. The pre-embedded component assembly device 230 alternately transfers the bolt sleeve 160 and the first wedge-shaped block 140 to the flange 120 in sequence.

[0104] The first driving assembly 211 is used to drive the flange 120 to rotate. After the bolt 130 and the bolt sleeve 160 are connected in the first flange hole 121, the first driving assembly 211 drives the flange 120 to rotate by a predetermined angle, and the first wedge-shaped block 140 is transferred to the flange 120 by the embedded part assembling device 230, and the first wedge-shaped block 140 is arranged side by side with the bolt sleeve 160. Then, the first driving assembly 211 drives the flange 120 to rotate by a predetermined angle, and the second flange hole 121 reaches the position where the bolt 130 and the bolt sleeve 160 are to be assembled. In this way, the first driving assembly 211 drives the flange 120 to rotate until the last flange hole 121 reaches the position where the bolt 130 and the bolt sleeve 160 are to be assembled.

[0105] In some implementable manners, the bolt sleeve 160 on the material conveying assembly 221 is in an upright state, and the axial direction of the bolt sleeve 160 is the same as the vertical direction. The tapered hole 161 of the bolt sleeve 160 faces upward. The first wedge-shaped block 140 on the material conveying assembly 221 is in an upright state.

[0106] In some implementable manners, the semicircular flange 120 can be lifted onto the horizontal support platform 212 by a lifting tool. After the sliding seat 213 is fixedly connected with the flange 120, the embedded part assembling device 230 can transfer the material in the assembly station to above the flange 120. When the embedded part assembling device 230 transfers the bolt sleeve 160 to above the flange 120, the bolt sleeve 160 is aligned with the flange hole 121 in the vertical direction. Then, the bolt installing device 240 transfers the bolt 130 to below the flange 120, and connects the bolt 130 with the bolt sleeve 160 in the vertical direction through the flange hole 121.

[0107] After the assembly of the blade root embedded assembly 100 is completed, the sliding seat 213 can be separated from the flange 120. The blade root embedded assembly 100 is lifted by a lifting tool and removed from the horizontal support platform 212, so as to complete the blanking of the blade root embedded assembly 100.

[0108] In some implementable manners, in the assembled blade root embedded assembly 100, one first wedge-shaped block 140 is provided with a bolt sleeve 160 on one side and a bolt sleeve 160 on the other side along the circumference of the flange 120. The first wedge-shaped block 140 can be limited and constrained by the bolt sleeves 160 on both sides, so that the first wedge-shaped block 140 will not fall off.

[0109] In some implementable manners, after the corresponding bolt 130 and bolt sleeve 160 are sequentially connected and fixed to each flange hole 121, the plurality of bolts 130, the plurality of first wedge blocks 140 and the flange 120 form the blade root pre-embedded assembly 100. The blade root pre-embedded assembly 100 can be stored as a whole in a predetermined area. When the blade root 40 needs to be formed, the blade root pre-embedded assembly 100 can be transferred as a whole to the blade root 40 mold.

[0110] In some implementable manners, the second wedge block 150 can be arranged on the blade root pre-embedded assembly 100. The second wedge block 150 can be inserted into the gap between two adjacent first wedge blocks 140. The tapered section 151 of the second wedge block 150 is inserted and fixed with the tapered hole 161 of the bolt sleeve 160. One second wedge block 150 is arranged corresponding to one bolt sleeve 160. The bolt sleeve 160 and the second wedge block 150 are arranged along the axial direction of the flange 120. The first wedge block 140 and the second wedge block 150 are alternately arranged along the circumferential direction of the flange 120. The blade root pre-embedded assembly 100 and the second wedge block 150 form a composite structure. When the blade root 40 needs to be formed, the composite structure formed by the blade root pre-embedded assembly 100 and the second wedge block 150 can be transferred as a whole to the blade root 40 mold.

[0111] The wind turbine blade blade root pre-embedded assembly assembly equipment 200 of the embodiment of the application, through the flange fixing device 210, the feeding device 220, the pre-embedded part assembly device 230 and the bolt mounting device 240, improves the automation degree of the blade root pre-embedded assembly 100 assembly, is conducive to improving the blade root pre-embedded assembly 100 assembly product quality, and is also conducive to improving the blade root pre-embedded assembly 100 assembly work efficiency. In the blade root pre-embedded assembly 100 assembled by the wind turbine blade blade root pre-embedded assembly assembly equipment 200, the position precision of each pre-embedded part 110 is high, which is conducive to improving the quality of the formed blade root 40. The way of assembling the blade root pre-embedded assembly 100 by the wind turbine blade blade root pre-embedded assembly assembly equipment 200 transfers the assembly process of each pre-embedded part 110 to outside the blade root 40 mold, does not need to assemble each pre-embedded part 110 in the blade root 40 mold by manual way, reduces the mold time occupied, is conducive to improving the production efficiency, and reduces the labor input and labor intensity.

[0112] In some implementable manners, referring to Figure 10 The first driving assembly 211 includes a power output shaft 215. The axis of the power output shaft 215 is coaxially arranged with the axis of the annular horizontal guide rail 214. The power output shaft 215 is used for being connected and fixed with the flange 120, and the axis of the power output shaft 215 is coaxially arranged with the axis of the flange 120. In some examples, the power output shaft 215 and the flange 120 can be connected and fixed by screws or pins.

[0113] The first drive assembly 211 drives the flange 120 to rotate via the power output shaft 215. The axis of the power output shaft 215 is coaxial with the axis of the annular horizontal guide rail 214, which helps to ensure the stable movement of the slide 213 and the flange 120 on the annular horizontal guide rail 214. At the same time, it helps to accurately control the rotation angle of the flange 120 so that the bolt sleeve 160 or the first wedge block 140 can be accurately transferred to the predetermined position on the flange 120, thereby improving the installation accuracy of the bolt sleeve 160 or the first wedge block 140 and improving the quality of the formed blade root 40.

[0114] In some examples, the first drive assembly 211 can be an intermittent drive assembly. The power output shaft 215 of the first drive assembly 211 rotates intermittently. After the power output shaft 215 drives the flange 120 to rotate by a predetermined angle, the power output shaft 215 stops rotating so that the embedded part assembly device 230 can install the bolt sleeve 160 or the first wedge block 140 into place. Then the power output shaft 215 rotates, driving the flange 120 to rotate by a predetermined angle again, and this process is repeated until the last flange hole 121 on the flange 120 rotates to the position where the bolt sleeve 160 is to be installed.

[0115] After the corresponding bolts 130 and bolt sleeves 160 are connected and fixed in sequence to the corresponding flange holes 121, the first drive assembly 211 drives the flange 120 to rotate to the unloading position, and then the blade root pre-embedded assembly 100 is hoisted as a whole and removed from the horizontal support platform 212 by the lifting tool to complete the unloading.

[0116] In some examples, the first drive component 211 can be a cam divider.

[0117] In some examples, the first drive component 211 may include a motor and a reducer. The motor is connected to the reducer. The reducer includes a power output shaft. Exemplarily, the reducer may be a gear reducer.

[0118] See also some of the possible implementation methods. Figure 10 and Figure 11 As shown, the horizontal support platform 212 includes a circular top plate 2121, an annular side plate 2122, and support feet 2123. An annular horizontal guide rail 214 is provided on the upper surface of the circular top plate 2121. The circular top plate 2121 and the annular side plate 2122 are connected, enclosing a receiving space. The main body 30 of the first drive assembly 211 can be disposed within the receiving space. A power output shaft 215 extends from the center of the circular top plate 2121. The annular side plate 2122 is connected to the support feet 2123. The support feet 2123 are used to support the horizontal support platform 212.

[0119] In some possible implementations, the horizontal support platform 212 can be configured to mount flanges 120 with different pitch circle diameters. The pitch circle diameter of the flanges 120 can range from 2800 mm to 3600 mm.

[0120] In some possible implementations, referring to Figure 12 The feeding device 220 includes a material anti-toppling assembly 222, as shown. The material anti-toppling assembly 222 is connected to a material conveying assembly 221. The material conveying assembly 221 includes a first annular conveying member 223. The first annular conveying member 223 is configured to convey the material to be assembled. The material anti-toppling assembly 222 is arranged on both sides of the first annular conveying member 223 in the horizontal direction. The material anti-toppling assembly 222 is configured to limit the material to be assembled on the first annular conveying member 223.

[0121] During the conveying of the material to be assembled by the first annular conveying member 223, the material can pass through the channel formed by the material anti-toppling assembly 222 on both sides. The material anti-toppling assembly 222 can protect the material on both sides, so that the material is less likely to topple during the conveying process, which is conducive to improving the stability of the material conveying, reducing the possibility of frequent shutdown of the feeding device 220 due to the toppling of the material, and improving the production efficiency.

[0122] In some examples, the first annular conveying member 223 includes a conveying belt or a conveying chain. The material conveying assembly 221 includes a driving roller, a driven roller, and a motor. The first annular conveying member 223 is arranged on the driving roller and the driven roller. The motor drives the driving roller to rotate. The driving roller drives the first annular conveying member 223 and the driven roller to rotate.

[0123] In some examples, referring to Figure 12 The material anti-toppling assembly 222 includes a first vertical support 224, a first horizontal rod 225, a second horizontal rod 226, and a first position adjusting component 227. The first vertical support 224 is connected to the material conveying assembly 221. The first horizontal rod 225 is connected to the first vertical support 224. The second horizontal rod 226 is connected to the first position adjusting component 227. The first position adjusting component 227 is configured to adjust the position of the second horizontal rod 226 in the horizontal direction, so as to adjust the horizontal distance between the second horizontal rods 226 on both sides of the first annular conveying member 223.

[0124] The first vertical support 224 can provide a mounting basis for the first horizontal rod 225, facilitating the mounting and fixation of the first horizontal rod 225. The first horizontal rod 225 and the second horizontal rod 226 are respectively configured to protect the material at different positions of the material, reducing the possibility of toppling of the material.

[0125] The second transverse rods 226 are adjusted in horizontal spacing by the first position adjustment component 227, so that the material anti-toppling assembly 222 can be adapted to materials of different sizes, such as bolt sleeves 160 of different diameters or first wedge-shaped blocks 140 of different widths. By adjusting the horizontal spacing between the second transverse rods 226, the material anti-toppling assembly 222 and the material can be kept in relatively small clearance, reducing the possibility of the material toppling due to the relatively large clearance between the material anti-toppling assembly 222 and the material of smaller size.

[0126] In some examples, the first transverse rods 225 are located above the second transverse rods 226. The first transverse rods 225 and the second transverse rods 226 are both round rods, which can reduce the contact area between the first transverse rods 225 and the second transverse rods 226 and the material, reducing the possibility of the material toppling along the conveying direction of the first annular conveying member 223 due to the large frictional resistance between the first transverse rods 225 and the second transverse rods 226 and the material.

[0127] In some examples, the first vertical support 224 is provided with the first position adjustment component 227.

[0128] In some examples, as shown in Figure 12 and Figure 14 The first position adjustment component 227 includes first clamping blocks 2271 and a first adapter 2272. The first adapter 2272 includes a first shaft body 2273 and a first clamping portion 2274. The two first clamping blocks 2271 clamp the first shaft body 2273. The second transverse rods 226 are clamped with the first clamping portion 2274.

[0129] The first shaft body 2273 is axially aligned with the horizontal direction. The first clamping portion 2274 is arranged on the end of the first shaft body 2273 facing the first annular conveying member 223. The two first clamping blocks 2271 apply clamping force to the first shaft body 2273. When the position of the second transverse rods 226 needs to be adjusted, the first shaft body 2273 moves relative to the two first clamping blocks 2271. By clamping the first shaft body 2273 with the two first clamping blocks 2271, the overall structure of the first position adjustment component 227 is relatively simple, reducing the manufacturing difficulty of the first position adjustment component 227. At the same time, the adjustment operation of the first shaft body 2273 is simple and convenient, which can reduce the difficulty of the position adjustment of the second transverse rods 226 and improve the work efficiency.

[0130] In some realizable ways, as shown in Figure 15 and Figure 16As shown, the feeding device 220 comprises a material sorting and limiting assembly 228. The material sorting and limiting assembly 228 is arranged on the material conveying assembly 221. When the material conveying assembly 221 stops conveying, the material sorting and limiting assembly 228 is used to contact and limit the to-be-assembled material located on the material conveying assembly 221. When the material conveying assembly 221 starts conveying, the material sorting and limiting assembly 228 releases the to-be-assembled material, so that the to-be-assembled material is transferred to the assembly station.

[0131] The material on the material conveying assembly 221 is limited by the material sorting and limiting assembly 228 before reaching the assembly station. The material sorting and limiting assembly 228 can make the materials on the material conveying assembly 221 be sequentially conveyed to the assembly station, thereby improving the orderliness of the material conveying process.

[0132] When the previous material on the material conveying assembly 221 reaches the assembly station, the material conveying assembly 221 stops conveying, and at the same time, the material sorting and limiting assembly 228 can contact and limit the subsequent material. After the material on the assembly station is completed, the material conveying assembly 221 starts conveying, and the material sorting and limiting assembly 228 can release the subsequent material, so that the subsequent material can reach the assembly station.

[0133] In some examples, the number of the material sorting and limiting assembly 228 is two. The two material sorting and limiting assemblies 228 are arranged along the material conveying direction. For example, the two material sorting and limiting assemblies 228 can be respectively used to contact and limit the first material and the second material close to the assembly station.

[0134] In some examples, referring to Figure 16 As shown, the material sorting and limiting assembly 228 comprises a second driving assembly 2281 and a first horizontal telescopic shaft 2282. The first horizontal telescopic shaft 2282 is connected with the second driving assembly 2281. The second driving assembly 2281 is used to drive the first horizontal telescopic shaft 2282 to perform telescopic movement, so that the first horizontal telescopic shaft 2282 contacts and limits the to-be-assembled material or releases the to-be-assembled material.

[0135] When the material conveying assembly 221 stops conveying, the second driving assembly 2281 drives the first horizontal telescopic shaft 2282 to extend. The first horizontal telescopic shaft 2282 extends to the front of the material. The first horizontal telescopic shaft 2282 contacts and limits the to-be-assembled material located on the material conveying assembly 221.

[0136] When the material conveying assembly 221 starts conveying, the second driving assembly 2281 drives the first horizontal telescopic shaft 2282 to retract. The first horizontal telescopic shaft 2282 releases the to-be-assembled material, and the first horizontal telescopic shaft 2282 avoids the to-be-assembled material, so that the material can be conveyed to the assembly station.

[0137] The material sorting limiting assembly 228 can quickly realize limiting or releasing the to-be-assembled material through the telescopic movement of the first horizontal telescopic shaft 2282, thereby improving the work efficiency.

[0138] Exemplarily, the second driving assembly 2281 can be a pneumatic cylinder or an electric cylinder.

[0139] In some possible implementation manners, referring to Figure 13 As shown in the figure, the embedded part assembling device 230 comprises a lifting moving assembly 231, a rotary driver 232 and a material clamping jaw 233. The lifting moving assembly 231 is connected to the rotary driver 232. The material clamping jaw 233 is connected to the lifting moving assembly 231. The rotary driver 232 is used to drive the lifting moving assembly 231 and the material clamping jaw 233 to rotate, so that the material clamping jaw 233 transfers the to-be-assembled material from the assembling station to above the flange 120. The lifting moving assembly 231 is used to drive the material clamping jaw 233 to ascend or descend along the vertical direction.

[0140] The material clamping jaw 233 is used to clamp the material at the assembling station. After the material clamping jaw 233 clamps the material, the rotary driver 232 drives the lifting moving assembly 231 and the material clamping jaw 233 to rotate, and the material clamping jaw 233 transfers the to-be-assembled material from the assembling station to above the flange 120. Then, the lifting moving assembly 231 drives the material clamping jaw 233 to descend along the vertical direction, so that the material clamping jaw 233 places the material at the predetermined position of the flange 120.

[0141] The material clamping jaw 233 releases the material, the lifting moving assembly 231 drives the material clamping jaw 233 to ascend along the vertical direction, the rotary driver 232 drives the lifting moving assembly 231 and the material clamping jaw 233 to rotate, and the material clamping jaw 233 clamps the next material at the assembling station again.

[0142] The rotary driver 232 drives the lifting moving assembly 231 and the material clamping jaw 233 to rotate horizontally.

[0143] The rotary driver 232 and the lifting moving assembly 231 are cooperated with each other, so that the material clamping jaw 233 smoothly transfers the material and improves the material transfer efficiency. The rotary driver 232 drives the material clamping jaw 233 to adjust the position, thereby reducing the possibility of position interference between the material clamping jaw 233 and the feeding device 220.

[0144] In some examples, the rotary driver 232 can comprise a motor and a speed reducer. The speed reducer is connected to the motor. The output end of the speed reducer is connected to the lifting moving assembly 231. The rotary axis of the output end of the speed reducer is a vertical axis.

[0145] In some examples, the lifting moving assembly 231 can include a pneumatic cylinder and a telescopic piece. The pneumatic cylinder drives the telescopic piece to perform telescopic movement. The telescopic piece is connected with the material gripper 233. The telescopic movement of the telescopic piece drives the material gripper 233 to perform lifting movement.

[0146] In some examples, the lifting moving assembly 231 can include an electric cylinder and a telescopic piece. The electric cylinder drives the telescopic piece to perform telescopic movement. The telescopic piece is connected with the material gripper 233. The telescopic movement of the telescopic piece drives the material gripper 233 to perform lifting movement.

[0147] In some examples, referring to Figure 13 The pre-embedded part assembling device 230 includes a horizontal moving assembly 234. The rotary driver 232 is connected with the horizontal moving assembly 234. The horizontal moving assembly 234 is used to drive the rotary driver 232, the lifting moving assembly 231 and the material gripper 233 to move along the horizontal direction, so that the material gripper 233 approaches or moves away from the assembling station.

[0148] After the material gripper 233 clamps the material, the horizontal moving assembly 234 drives the rotary driver 232, the lifting moving assembly 231 and the material gripper 233 to move along the horizontal direction, so that the material gripper 233 moves away from the assembling station. Then, the rotary driver 232 drives the lifting moving assembly 231 and the material gripper 233 to rotate, and the material gripper 233 transfers the material to be assembled from the assembling station to above the flange 120. The lifting moving assembly 231 drives the material gripper 233 to descend along the vertical direction, so that the material gripper 233 places the material at the predetermined position of the flange 120.

[0149] After the material gripper 233 releases the material, the lifting moving assembly 231 drives the material gripper 233 to ascend along the vertical direction, the rotary driver 232 drives the lifting moving assembly 231 and the material gripper 233 to rotate, the horizontal moving assembly 234 drives the rotary driver 232, the lifting moving assembly 231 and the material gripper 233 to move along the horizontal direction, so that the material gripper 233 approaches the assembling station, and the material gripper 233 can clamp the next material at the assembling station.

[0150] The horizontal moving assembly 234, the rotary driver 232 and the lifting moving assembly 231 cooperate with each other, so that the material gripper 233 can smoothly transfer the material and improve the material transfer efficiency. The horizontal moving assembly 234 and the rotary driver 232 drive the material gripper 233 to perform position adjustment, which is beneficial to reduce the possibility of position interference between the material gripper 233 and the feeding device 220.

[0151] Exemplarily, the horizontal moving assembly 234 can include a pneumatic cylinder and a telescopic piece. The pneumatic cylinder drives the telescopic piece to perform telescopic movement. The telescopic movement of the telescopic piece drives the rotary driver 232, the lifting moving assembly 231 and the material gripper 233 to move along the horizontal direction.

[0152] Exemplarily, the horizontal moving assembly 234 can include an electric cylinder and a telescopic piece. The electric cylinder drives the telescopic piece to perform telescopic movement. The telescopic movement of the telescopic piece drives the rotary driver 232, the lifting moving assembly 231 and the material gripper 233 to move along the horizontal direction.

[0153] Exemplarily, the pre-embedded part assembling device 230 includes a pneumatic cylinder. The pneumatic cylinder is used to drive the material gripper 233 to open and close.

[0154] In some possible implementations, referring to Figure 17 As shown, the bolt mounting device 240 includes a bolt feeding assembly 241 and a bolt mounting assembly 242. The bolt feeding assembly 241 and the bolt mounting assembly 242 are arranged in a spaced manner. The bolt feeding assembly 241 is used to convey the bolts 130. The bolt mounting assembly 242 is used to transfer the bolts 130 to the lower side of the flange 120, and connect the bolts 130 to the bolt sleeves 160 along the vertical direction through the flange holes 121.

[0155] The bolt feeding assembly 241 and the bolt mounting assembly 242 are arranged independently, so that the bolt feeding assembly 241 and the bolt mounting assembly 242 can be maintained or repaired individually, which is beneficial to reduce the difficulty of maintenance. When one of the bolt feeding assembly 241 and the bolt mounting assembly 242 fails, it can be replaced individually, which is beneficial to reduce the difficulty and cost of replacement.

[0156] In some examples, referring to Figure 18 and Figure 19 As shown, the bolt mounting assembly 242 includes a horizontal moving unit 243, a base 244, a bolt gripper 245 and a bolt screwing unit 246. The base 244 is arranged on the horizontal moving unit 243. The bolt gripper 245 and the bolt screwing unit 246 are arranged in a spaced manner along the vertical direction on the base 244. The bolt gripper 245 is located above the bolt screwing unit 246. The bolt gripper 245 is used to clamp the bolts 130. The horizontal moving unit 243 is used to drive the base 244, the bolt gripper 245 and the bolt screwing unit 246 to move horizontally synchronously. The bolt screwing unit 246 is used to screw the bolts 130.

[0157] When the bolt clamping jaw 245 is required to clamp the bolt 130, the horizontal moving unit 243 drives the base 244, the bolt clamping jaw 245 and the bolt screwing unit 246 to move horizontally synchronously, and the bolt clamping jaw 245 approaches the bolt 130 to be assembled on the bolt feeding assembly 241. After the bolt clamping jaw 245 clamps the bolt 130, the horizontal moving unit 243 drives the base 244, the bolt clamping jaw 245 and the bolt screwing unit 246 to move horizontally synchronously, and the bolt clamping jaw 245 transfers the bolt 130 clamped to the position below the flange 120 and aligns the bolt 130 with the corresponding flange hole 121. The bolt screwing unit 246 is connected with the bolt 130. The bolt clamping jaw 245 releases the bolt 130. The bolt screwing unit 246 screws the bolt 130, so that the bolt 130 is connected and fixed with the bolt sleeve 160 on the flange 120.

[0158] The horizontal moving unit 243, the base 244, the bolt clamping jaw 245 and the bolt screwing unit 246 are cooperated with each other, so as to improve the automation degree of the bolt 130 installation, and improve the precision and working efficiency of the bolt 130 installation.

[0159] Exemplarily, when the horizontal support platform 212 fixes the flange 120, the bolt installation device 240 is located below the flange 120.

[0160] Exemplarily, the bolt installation assembly 242 comprises a pneumatic cylinder. The pneumatic cylinder is used to drive the bolt clamping jaw 245 to open and close.

[0161] In some examples, as shown in Figure 18 and Figure 19 Exemplarily, the bolt screwing unit 246 comprises a driving feeding mechanism 247 and a bolt tightening machine 248. The driving feeding mechanism 247 is connected with the base 244. The bolt tightening machine 248 is connected with the driving feeding mechanism 247. The driving feeding mechanism 247 is used to drive the bolt tightening machine 248 to approach or move away from the flange 120. The bolt tightening machine 248 is used to connect and screw the bolt 130.

[0162] During the process of the bolt screwing machine screwing the bolt 130, the driving feeding mechanism 247 synchronously drives the bolt screwing machine to move towards the flange 120, so that the bolt screwing machine is always connected with the bolt 130. After the bolt 130 is installed in place, the driving feeding mechanism 247 drives the bolt tightening machine 248 to move away from the flange 120, and the bolt tightening machine 248 is separated from the bolt 130. The driving feeding mechanism 247 drives the bolt tightening machine 248 to return to the original position.

[0163] The driving feeding mechanism 247 and the bolt tightening machine 248 are cooperated with each other, so as to improve the automation of the bolt 130 installation process, and improve the precision and working efficiency of the bolt 130 installation.

[0164] In some examples, the bolt screwing unit 246 can record the torque information when the bolt 130 is screwed, save the torque value, so as to facilitate the judgment of whether the torque is qualified and the quality traceability.

[0165] In some examples, referring to Figs. 24 and 25, the bolt tightening machine 248 comprises a servo motor 2481, a speed reducer 2482 and a sleeve 2483. The sleeve 2483 is connected with the output end of the speed reducer 2482. The speed reducer 2482 is connected with the servo motor 2481. The sleeve 2483 is used for connecting the bolt 130. The servo motor 2481 and the speed reducer 2482 are used for driving the sleeve 2483 to rotate, so as to screw the bolt 130 by the sleeve 2483. Figure 18 Figure 19 In some examples, referring to Figs. 24 and 25, the bolt tightening machine 248 comprises a servo motor 2481, a speed reducer 2482 and a sleeve 2483. The sleeve 2483 is connected with the output end of the speed reducer 2482. The speed reducer 2482 is connected with the servo motor 2481. The sleeve 2483 is used for connecting the bolt 130.

The sleeve 2483 is connected with the output end of the speed reducer 2482. The speed reducer 2482 is connected with the servo motor 2481. The sleeve 2483 is used for connecting the bolt 130. The servo motor 2481 and the speed reducer 2482 are used for driving the sleeve 2483 to rotate, so as to screw the bolt 130 by the sleeve 2483.

[0167] The sliding table 2472 can move along the vertical direction relative to the support 2471. The support 2471 can carry the bolt tightening machine 248 and can guide the bolt tightening machine 248, so as to improve the moving stability of the bolt tightening machine 248 and reduce the possibility of shaking of the bolt tightening machine 248 during the screwing of the bolt 130.

[0168] In some examples, the driving mechanism 2473 comprises a motor and a lead screw. The lead screw is connected with the motor and the sliding table 2472. The motor drives the lead screw to rotate. The lead screw drives the sliding table 2472 to move relative to the support 2471.

The sleeve 2483 is connected with the output end of the speed reducer 2482. The speed reducer 2482 is connected with the servo motor 2481. The sleeve 2483 is used for connecting the bolt 130.

[0170] ​​​During the process of conveying the bolts 130 to be assembled by the second annular conveyor 2411, the bolts 130 can pass through the channels formed by the bolt anti-tipping components 2412 on both sides. The bolt anti-tipping components 2412 can protect the bolts 130 on both sides, making it less likely for the bolts 130 to tip over during the conveying process. This helps to improve the conveying stability of the bolts 130, reduces the possibility of frequent shutdowns of the bolt feeding assembly 241 due to the tipping of the bolts 130, and helps to improve production efficiency.

[0171] In some examples, the second annular conveyor 2411 includes a conveyor belt or conveyor chain. The bolt feeding assembly 241 includes a drive roller, a driven roller, and a motor. The second annular conveyor 2411 is disposed on the drive roller and the driven roller. The motor drives the drive roller to rotate. The drive roller drives the second annular conveyor 2411 and the driven roller to rotate.

[0172] See in some examples Figure 20 and Figure 21 As shown, the bolt anti-tipping component 2412 includes a second vertical support 2413, a third horizontal bar 2414, a fourth horizontal bar 2415, and a second position adjustment component 2416. The third horizontal bar 2414 is connected to the second vertical support 2413. The fourth horizontal bar 2415 is connected to the second position adjustment component 2416. The second position adjustment component 2416 is used to adjust the position of the fourth horizontal bar 2415 in the horizontal direction to adjust the horizontal distance between the fourth horizontal bars 2415 on both sides of the second annular conveyor 2411.

[0173] The second vertical support 2413 can provide an installation base for the third horizontal bar 2414, facilitating its installation and fixation. The third horizontal bar 2414 and the fourth horizontal bar 2415 are used to protect the bolt 130 at different positions, reducing the possibility of the bolt 130 tipping over.

[0174] By adjusting the horizontal spacing between the fourth transverse bars 2415 using the second position adjustment component 2416, the bolt anti-tipping component 2412 can be adapted to bolts 130 of different sizes. This adjustment also ensures a relatively small gap between the bolt anti-tipping component 2412 and the bolt 130, reducing the likelihood of the bolt 130 easily tipping over due to a relatively large gap between the bolt anti-tipping component 2412 and the smaller bolt 130.

[0175] In some examples, the third transverse rod 2414 is located above the fourth transverse rod 2415. The third transverse rod 2414 and the fourth transverse rod 2415 are both round rods, which is conducive to reducing the contact area between the third transverse rod 2414 and the bolt 130 and the contact area between the fourth transverse rod 2415 and the bolt 130, and reducing the possibility of material dumping along the conveying direction of the second annular conveying member 2411 due to large frictional resistance between the third transverse rod 2414 and the bolt 130 and between the fourth transverse rod 2415 and the bolt 130.

[0176] In some examples, the second vertical support 2413 is provided with a second position adjusting component 2416.

[0177] In some examples, as shown in Figure 20 and Figure 21 , the second position adjusting component 2416 includes a second clamping block 2417 and a second adapter 2418. The second adapter 2418 includes a second shaft body 24181 and a second clamping portion 24182. The two second clamping blocks 2417 clamp the second shaft body 24181. The fourth transverse rod 2415 is clamped with the second clamping portion 24182.

[0178] The axial direction of the second shaft body 24181 is the same as the horizontal direction. The second clamping portion 24182 is arranged on the end of the second shaft body 24181 facing the second annular conveying member 2411. The two second clamping blocks 2417 apply clamping force to the second shaft body 24181. When it is necessary to adjust the position of the fourth transverse rod 2415, the second shaft body 24181 moves relative to the two second clamping blocks 2417. By clamping the second shaft body 24181 through the two second clamping blocks 2417, the overall structure of the second position adjusting component 2416 is relatively simple, which reduces the manufacturing difficulty of the second position adjusting component 2416. At the same time, the adjustment operation mode of the second shaft body 24181 is simple and convenient, which is conducive to reducing the difficulty of position adjustment of the fourth transverse rod 2415 and improving the work efficiency.

[0179] In some realizable modes, as shown in Figure 20 and Figure 21 , the bolt mounting device 240 includes a bolt sorting and limiting assembly 249. The bolt sorting and limiting assembly 249 is arranged on the bolt feeding assembly 241. When the bolt feeding assembly 241 stops conveying, the bolt sorting and limiting assembly 249 is used to contact and limit the bolt 130 to be assembled on the bolt feeding assembly 241. When the bolt feeding assembly 241 starts conveying, the bolt sorting and limiting assembly 249 releases the bolt 130 to be assembled.

[0180] Before reaching the assembly station, the bolts 130 on the bolt feeding assembly 241 are limited by the bolt sorting and limiting assembly 249. The bolt sorting and limiting assembly 249 enables the bolts 130 on the bolt feeding assembly 241 to be transported to the assembly station in sequence, which helps to improve the orderliness of the bolt transport process.

[0181] When the previous bolt 130 on the bolt feeding assembly 241 arrives at the assembly station, the bolt feeding assembly 241 stops conveying, and at the same time, the bolt sorting and limiting assembly 249 can contact and limit the subsequent bolt 130. After the bolt 130 at the assembly station has completed its transfer, the bolt feeding assembly 241 starts conveying again, and the bolt sorting and limiting assembly 249 can release the subsequent bolt 130 so that the subsequent bolt 130 can reach the assembly station.

[0182] In some examples, there are two bolt sorting limit components 249. The two bolt sorting limit components 249 are spaced apart along the bolt 130 conveying direction. Exemplarily, the two bolt sorting limit components 249 can be used to limit contact between the first bolt 130 and the second bolt 130 near the assembly station, respectively.

[0183] See in some examples Figure 21 As shown, the bolt sorting and limiting assembly 249 includes a third drive assembly 2491 and a second horizontal telescopic shaft 2492. The second horizontal telescopic shaft 2492 is connected to the third drive assembly 2491. The third drive assembly 2491 is used to drive the second horizontal telescopic shaft 2492 to extend and retract, so that the second horizontal telescopic shaft 2492 contacts and limits the bolt 130 to be assembled or releases the bolt 130 to be assembled.

[0184] When the bolt feeding assembly 241 stops conveying, the third drive assembly 2491 drives the second horizontal telescopic shaft 2492 to extend. The second horizontal telescopic shaft 2492 extends to the front of the bolt 130. The second horizontal telescopic shaft 2492 contacts and limits contact with the bolt 130 to be assembled on the bolt feeding assembly 241.

[0185] When the bolt feeding assembly 241 starts conveying, the third drive assembly 2491 drives the second horizontal telescopic shaft 2492 to retract. The second horizontal telescopic shaft 2492 releases the bolt 130 to be assembled and avoids the bolt 130 to be assembled, so that the bolt 130 can be conveyed to the assembly station.

[0186] The bolt sorting and limiting assembly 249 can quickly limit or release the material to be assembled by means of the telescopic movement of the second horizontal telescopic shaft 2492, which helps to improve work efficiency.

[0187] For example, the third drive component 2491 may be a cylinder or an electric cylinder.
