Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade production and processing technology, specifically to a feeding device for a wind turbine blade bolt winding machine. Background Technology

[0002] A wind turbine is a power generation device that converts wind energy into mechanical energy and then into electrical energy through blades. The blades are the key components of a wind turbine, and high-strength bolt sleeves are usually pre-embedded at the end face of the blade root, connecting the wind turbine blade and the hub together with bolts. To enhance the strength of the bolt sleeves embedded in the blade, fiberglass filaments are wound around the surface of the bolt sleeves. In existing technology, a wire winding machine is used to automatically wind the bolt sleeves. The wire winding machine includes a wire winding assembly, and a support assembly is usually located directly below the wire winding assembly. The bolt sleeve is placed on the support assembly, and the support assembly drives the bolt sleeve to rise until it is coaxial with the wire winding assembly. Then, the wire winding assembly fixes the bolt sleeve. The wire winding assembly usually includes a fixed first positioning sleeve and a telescopic second positioning sleeve, and the end faces of the first and second positioning sleeves have conical platforms that penetrate into the bolt sleeve to prevent the bolt sleeve from falling off the wire winding assembly during rotation. However, in use, it has been found that because the support assembly is very close to the wire cutting shears of the wire winding machine, it is easy to cut the back of the hand when placing the bolt sleeve on the support assembly. At the same time, when placing the bolt sleeve, there will be a certain gap between it and the first positioning sleeve to avoid the conical platform on the first positioning sleeve. Before fixing the bolt sleeve to the wire winding assembly, the second positioning sleeve will push the bolt sleeve to move horizontally a distance. During this process, the bolt sleeve is easy to tilt and become eccentric, which will affect the uniformity of the wire winding of the bolt sleeve. Utility Model Content

[0003] The purpose of this invention is to provide a feeding device for a wind turbine blade bolt sleeve winding machine. This feeding device can conveniently deliver the bolt sleeve to the rotating component of the winding machine and prevent one end of the rotating component from pushing the bolt sleeve to move horizontally.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A feeding device for a wind turbine blade bolt sleeve winding machine includes a first slide rail, which is fixedly mounted on the frame of the winding machine and extends to the outside of the frame. A first slide block is slidably mounted on the first slide rail, and a lifting seat that can move up and down is provided on the first slide block. A second slide block that slides along the length of the winding machine frame is provided on the lifting seat. At least two sets of positioning blocks are provided in the middle of the second slide block, and the positioning blocks are provided with V-grooves or U-grooves that match the size of the bolt sleeve.

[0006] Preferably, it includes a base, which is fixedly connected to the lower side of the positioning and rotating assembly of the winding machine, and the first slide rail is fixedly connected to the base; a first driving part is fixedly connected to the base, and the first driving part drives the first slide to slide on the first slide rail.

[0007] Preferably, the first slide rail has two tracks, and the first slide block includes two vertical plates and a horizontal plate. The vertical plates are connected to both sides of the horizontal plate to form a portal structure. A first slider that cooperates with the first slide rail is fixedly connected to the bottom side of the vertical plate. A reinforcing plate is also fixedly connected between the two vertical plates, and the middle part of the reinforcing plate is fixedly connected to the output end of the first drive unit.

[0008] Preferably, two second slide rails are fixedly connected to the upper surface of the lifting seat, and a second slider that cooperates with the second slide rail is fixedly connected to the bottom side of the second slide rail; a second driving unit is also provided on the lifting seat, and the output end of the second driving unit is fixedly connected to the second slide rail to drive the second slide rail to slide on the second slide rail.

[0009] Preferably, a third drive unit is fixedly connected to the horizontal plate, and the output end of the third drive unit is fixedly connected to the lower side of the lifting seat; a guide rod is also provided on the lower side of the lifting seat, and a guide sleeve that cooperates with the guide rod is provided on the horizontal plate, and the guide rod slides up and down in the guide sleeve.

[0010] Preferably, the first slide is perpendicular to the axis of the positioning and rotating assembly of the winding machine, and the second slide is parallel to the axis of the positioning and rotating assembly of the winding machine.

[0011] Preferably, a photoelectric sensor is also provided around the second slide block to detect the bolt sleeve placed on the positioning block.

[0012] Preferably, it further includes a control unit, wherein the first drive unit, the second drive unit, the third drive unit, and the through-beam sensor are all electrically connected to the control unit.

[0013] The beneficial effects of this utility model are:

[0014] By extending the first slide rail and the first slide block to the outside of the winding machine frame, loading and unloading of materials from the outside of the winding machine is convenient, avoiding the problem of workers being scratched. Simultaneously, workers no longer need to operate on the winding machine, allowing a cover to be installed to enclose it, isolating the machine from the external environment and effectively preventing dust generated during the fiberglass winding process from affecting worker health. The horizontally positioned second slide block causes the bolt sleeve to actively move towards the rotating winding assembly and form pre-contact. Then, the second positioning sleeve can directly clamp and fix the bolt sleeve onto the first positioning sleeve. Compared to the existing technology where the second positioning sleeve pushes the bolt sleeve horizontally for clamping and fixing, this effectively avoids the problem of the bolt sleeve tilting or becoming eccentric.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 4As shown, a feeding device for a wind turbine blade bolt sleeve winding machine includes a base 41, which is fixedly connected to the frame 1 of the winding machine. A first slide rail 42 is fixedly connected to the base 41. The first slide rail 42 is located below the positioning and rotating assembly 2 of the winding machine and is perpendicular to the axis of the positioning and rotating assembly 2, i.e., perpendicular to the axis of the bolt sleeve 3. The first slide rail 42 extends to the outside of the frame 1 of the winding machine. A first slide block 43 is slidably arranged on the first slide rail 42. The first slide block 43 is lower than the lower surface of the positioning and rotating assembly 2 to facilitate the movement of the bolt sleeve. The first slide block 43 is provided with a lifting seat 46 that can move up and down. A second slide block 47 is provided on the lifting seat 46. The second slide block 47 slides along the length direction of the frame 1 of the winding machine. At least two sets of positioning blocks 48 are provided in the middle of the second slide block 47. The positioning blocks 48 are provided with V-grooves 481 or U-grooves that match the size of the bolt sleeve. The V-grooves 481 or U-grooves allow the bolt sleeve to roll. When it is necessary to place the bolt sleeve, the first slide block 43 extends along the first slide rail 42 to the outside of the wire winding machine frame 1. The worker places the bolt sleeve 3 in the V-groove 481. The first slide block 43 retracts along the first slide rail 42 to the area directly below the axis of the positioning rotating assembly 2. Then, the lifting seat 6 moves upward to make the bolt sleeve 3 coaxial with the positioning rotating assembly 2. Finally, the second slide block 47 slides along the axis of the bolt sleeve 3 to one end of the positioning rotating assembly 2 and makes the end face of the bolt sleeve contact one end of the positioning rotating assembly 2. At this time, the other end of the positioning rotating assembly 2 moves toward the bolt sleeve, thereby stably clamping and fixing the bolt sleeve on the positioning rotating assembly 2, thus avoiding the problem of eccentricity caused by the positioning rotating assembly 2 pushing the bolt sleeve to move horizontally. After the wire winding is completed, the feeding device 4 moves to the lower side of the positioning and rotating assembly 2 and puts the bolt sleeve 3 into the V-groove 481. The positioning and rotating assembly 2 loosens the bolt sleeve 3, the second slide 47 drives the bolt sleeve 3 to move in the opposite direction to avoid the conical platform on the end face of the positioning and rotating assembly 2, and the lifting seat 46 descends. Finally, the first slide 43 drives the bolt sleeve 3, which has completed the wire winding, to slide to the outside of the frame 1 for easy replacement of a new bolt sleeve.

[0022] A first driving unit 44 is fixedly connected to the base 41, and the first driving unit 44 drives the first slide block 43 to slide on the first slide rail 42. Further, the first slide rail 42 has two sections, and the first slide block 43 includes two vertical plates 431 and a horizontal plate 432. The vertical plates 431 are connected to both sides of the horizontal plate 432 to form a portal structure. A first slider 45 that mates with the first slide rail 42 is bolted to the bottom side of the vertical plates 431. A reinforcing plate 433 is also fixedly connected between the two vertical plates 431. The middle part of the reinforcing plate 433 is fixedly connected to the output end of the first driving unit 44. Preferably, the first driving unit 44 is a driving cylinder, and the extension rod of the driving cylinder drives the first slide block 43 to slide on the first slide rail 42. Further, an ear plate 435 is fixedly connected to the bottom side of the vertical plates 431, and the first slider 45 is screwed to the ear plate 435.

[0023] A third drive unit 462 is fixedly connected to the lower side of the horizontal plate 432, and the output end of the third drive unit 462 is fixedly connected to the middle of the lower side of the lifting seat 46. Preferably, the third drive unit 462 is a cylinder, and the extension rod of the cylinder drives the lifting seat 46 to move up and down. Furthermore, several vertical guide rods 463 are also provided on the lower side of the lifting seat 46. The guide rods 463 are arranged around the lifting seat 46, and guide sleeves 434 that cooperate with the guide rods 463 are provided on the horizontal plate 432. When the lifting seat 46 moves up and down, the guide rods 463 slide up and down in the guide sleeves 434, thereby improving the stability of the lifting movement of the lifting seat 46.

[0024] Two second slide rails 461 are fixedly connected to the upper surface of the lifting seat 46. The second slide rails 461 are parallel to the axis of the positioning and rotating assembly 2 of the winding machine. A second slider 471 that cooperates with the second slide rails 461 is fixedly connected to the bottom side of the second slide seat 47. A second drive unit 472 is also provided on the lifting seat 46. The output end of the second drive unit 472 is fixedly connected to the second slide seat 47 to drive the second slide seat 47 to slide on the second slide rails 461 through the second slider 471. Preferably, the second drive unit 472 is a cylinder.

[0025] A bracket 491 is also provided around the second slide block 43. A through-beam sensor 49 is installed on the bracket 491. The through-beam sensor 49 is used to detect the bolt sleeve placed on the positioning block 48. Preferably, two sets of through-beam sensors 49 are provided, and they are respectively located on both sides of the positioning block 48. When the signal of the through-beam sensor 49 is blocked, it indicates that the bolt sleeve 3 is placed on the positioning block 48. At this time, the feeding device 4 moves closer to the positioning rotating assembly 2 to feed the material or moves away from the positioning rotating assembly 2 to unload the material. When the through-beam sensor 49 can detect the signal, it indicates that the bolt sleeve 3 is not placed on the positioning block 48 or the bolt sleeve is not placed in place. At this time, the feeding device will not operate.

[0026] In one embodiment, a control unit (not shown in the figures) is also included. The first driving air unit 44, the second driving unit 472, the third driving unit 762 and the through-beam sensor 49 are all electrically connected to the control unit. The control unit issues commands based on the signals fed back by the through-beam sensor 49 to drive the first driving air unit 44, the second driving unit 472 or the third driving unit 762 to perform corresponding actions.

[0027] In one embodiment, the positioning and rotating assembly 2 of the wire winding machine includes a first positioning sleeve 21 and a second positioning sleeve 22, which are coaxially arranged. The two ends of the bolt sleeve 3 are respectively fixed to the first positioning sleeve 21 and the second positioning sleeve 22. The first positioning sleeve 21 drives the bolt sleeve 3 to rotate, and the extension and retraction of the second positioning sleeve 22 fixes the bolt sleeve between the first and second positioning sleeves 22. A conical platform 23 is provided on the end face of both the first and second positioning sleeves 21 to prevent the bolt sleeve from falling off.

[0028] In use, when the bolt sleeve 3 needs to be placed, the first drive unit 44 drives the first slide 43 to extend to the outside of the winding machine frame 1. The worker places the bolt sleeve 3 in the V-groove 481. The through-beam sensor 49 detects the signal interruption and feeds it back to the control unit. The control unit controls the first drive unit 44 to move, so that the first slide 43 retracts to directly below the axis of the positioning rotation assembly 2. Then, the third drive unit 462 drives the lifting seat 6 to move upward so that the bolt sleeve 3 is coaxial with the positioning rotation assembly 2. Finally, the second drive unit 472 drives the second slide 47 to slide along the axis of the bolt sleeve 3 to the end face of the first positioning sleeve 21 and put the bolt sleeve 3 on the conical platform 23 until it contacts the end face of the first positioning sleeve 21. At this time, the second positioning sleeve 22 moves toward the bolt sleeve 3 and clamps and fixes the bolt sleeve 3 between the first positioning sleeve 21 and the second positioning sleeve 22, thereby stably clamping and fixing the bolt sleeve on the positioning rotation assembly 2.

[0029] After the wire winding is completed, the feeding device moves to the lower side of the positioning and rotating assembly 2, the lifting seat 46 rises and the bolt sleeve 3 enters the V-groove 481, then the second positioning sleeve 22 loosens the bolt sleeve 3, the second slide 47 drives the bolt sleeve 3 to move in the opposite direction to avoid the conical platform on the first positioning sleeve 21, and finally the lifting seat 46 descends, the first slide 43 drives the bolt sleeve 3 with the completed wire winding to slide to the outside of the frame 1, which is convenient for replacing the new bolt sleeve.

[0030] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
