Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of wind power blades, in particular to a feeding device for a wire winding machine of a bolt sleeve of a wind power blade. Background Art

[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 key components of the wind turbine. Generally, high-strength bolt sleeves are embedded at the end face of the blade root and connected to the hub as a whole through bolts. In order to enhance the strength of the bolt sleeve embedded in the blade, glass fiber filaments are wound on the surface of the bolt sleeve. In the prior art, the process of winding glass fiber filaments on the bolt sleeve mainly adopts a semi-automatic winding scheme, that is, a bolt sleeve is manually inserted into a mandrel with rotational power, and several glass fiber filament heads are manually fixed on the bolt sleeve. Then, the mandrel is started to rotate, and the glass fiber filaments are wound on the bolt sleeve. After the winding is completed, the tail of the glass fiber filament is knotted on the bolt sleeve to prevent the glass fiber filament from falling off the bolt sleeve. However, in the above process, when manually fixing the glass fiber filament to the bolt sleeve, affected by the proficiency and operation stability of the operator, different fixing methods are used. When starting to wind the glass fiber filament, the operator will leave an overly long head of the glass fiber filament to avoid being scratched, resulting in the phenomenon that the head of the glass fiber filament extends beyond the bolt sleeve. Moreover, the glass fiber filament is very sharp and is prone to scratching the fingers during the manual winding process. At the same time, if the glass fiber dust is inhaled, it is very harmful to the human body. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below with reference to the drawings through specific embodiments:

[0024] As Figures 1 to 6As shown in the figure, an upper line device for a wind power blade bolt sleeve winding machine includes a frame 1, on which a support assembly 10 and a winding assembly 70 are arranged. The support assembly 10 is used to fix the bolt sleeve 100 and drive the bolt sleeve 100 to rotate; the winding assembly 70 includes a rotatable shaft sleeve 73, which is coaxially arranged with the bolt sleeve 100 and can rotate around the axis of the bolt sleeve 100. A winding clamp 808 is fixedly connected to the end of the shaft sleeve 73. The winding clamp 80 includes a fixed clamp 82 and a movable clamp 83 arranged below the fixed clamp 82. The movable clamp 83 opens and loosens the fiberglass wire wound on the bolt sleeve 100 relative to the fixed clamp 82, and the movable clamp 83 bites and clamps the fiberglass wire relative to the fixed clamp 82 and drives the fiberglass wire to rotate to wind the fiberglass wire on the bolt sleeve 100. The winding clamp 80 clamps the end of the fiberglass wire and then rotates around the axis of the bolt sleeve 100 to wind the end of the fiberglass wire on the bolt sleeve. Then the support assembly 100 drives the bolt sleeve 100 to rotate to press the fiberglass wire wound by the previous winding clamp 80. The winding clamp 80 loosens the end of the fiberglass wire, and the bolt sleeve 100 accelerates to rotate to start wire winding.

[0025] The winding assembly 70 further includes a base 71 and a first slide rail 101. The first slide rail 101 is arranged along the length direction of the bolt sleeve 100. The base 71 is slidably arranged on the first slide rail 101. A support seat 72 is fixedly arranged on the base 71. The shaft sleeve 73 is rotatably arranged on the support seat 72. The shaft sleeve 73 is coaxially arranged with the support assembly 10, and one end of the support assembly 10 passes through the shaft sleeve 73; one end of the shaft sleeve 73 is rotatably connected to an eighth driving member 74, and a winding clamp 80 is arranged at the end of the other end. In this way, when wire winding operation is not required, the base 71 drives the shaft sleeve 73 and the winding clamp 80 to move along the axis of the bolt sleeve 100 away from the surface of the bolt sleeve 100, avoiding the winding clamp 80 affecting the wire winding of the bolt sleeve. At the same time, the base 71 drives the shaft sleeve 73 and the winding clamp 80 to move along the axis of the bolt sleeve 100 to the middle of the surface of the bolt sleeve 100, so as to facilitate wire winding.

[0026] In a preferred case, a clamp seat 81 is arranged at the end of the shaft sleeve 73. The fixed clamp 82 is fixed on the clamp seat 81. The movable clamp 83 is rotatably arranged on the clamp seat 81. The movable clamp 83 is hinged with a linkage plate 84, and the other end of the linkage plate 84 is hinged with a pull rod 85. The other end of the pull rod 85 is connected with a ninth driving member 75. The ninth driving member 75 drives the pull rod 85 to reciprocate. The pull rod 85 drives the movable clamp 83 to bite or open through the linkage plate 84.

[0027] In a preferred case, the linkage plate 84 is vertically arranged on the clamping seat 82, the pull rod 85 is horizontally arranged on the clamping seat 81, a sliding block 86 is arranged between the linkage plate 84 and the clamping seat 81, and the sliding block 86 is hinged to the linkage plate 84 and the pull rod 85 through a triangular plate 861. When the pull rod 85 moves horizontally, the sliding block 86 and the linkage plate 84 move up and down, and the sliding block 86 and the linkage plate 84 limit each other to prevent tilting. Further, an avoidance groove 851 matching with the sliding block 86 is arranged on the pull rod 85 to avoid interference between the pull rod 85 and the sliding block 86.

[0028] In a preferred case, an installation seat 87 is further arranged on the base 71. A through hole 871 is arranged in the middle of the installation seat 87, and the rotating shaft sleeve 73 passes through the through hole 871; a ninth driving member 75 is fixedly connected to the installation seat 87, and an arc-shaped sliding groove 88 is fixedly connected to the output end of the ninth driving member 75. The arc-shaped sliding groove 88 is coaxially arranged with the support assembly 10; a clamping plate 89 is arranged at one end of the pull rod 85 far away from the moving clamp 83, and the clamping plate 89 is slidably clamped in the arc-shaped sliding groove 88. The ninth driving member 75 drives the arc-shaped sliding groove 88 to move along the axis of the support assembly 10, so as to drive the clamping plate 89 clamped in the arc-shaped sliding groove 88 to reciprocate, and further realize the reciprocating movement of the pull rod 85, that is, realize the opening or closing of the wire winding clamp. The base 71 drives the arc-shaped sliding groove 88 to move along the axis of the support assembly 10. When the wire winding clamp 80 rotates, the clamping plate 89 slides in the arc-shaped sliding groove 88.

[0029] In a preferred case, a rotating piece 90 is hinged to the middle of the pull rod 85. The upper end of the rotating piece 90 is hinged to the clamping seat 81, and a spring 92 is connected to the lower end of the rotating plate 90.

The first fixing plate 61 and the first clamping plate 62 are arranged oppositely. The first clamping plate 62 is connected with a fifth driving member 44. The fifth driving member 44 is used to drive the first clamping plate 62 to move vertically to approach the first fixing plate 61 to press the glass fiber yarn against the second fixing plate 61, or move away from the first fixing plate 61 to loosen the glass fiber yarn; a wire passing hole 47 is arranged at the end of the first fixing plate 61.

[0031] The first wire clamping part 60 presses down to clamp the glass fiber yarn. The wire winding clamp 80 rotates to make the fixed clamp 82 pick and press the glass fiber yarn, which facilitates the moving clamp 83 to lift and close to clamp the glass fiber yarn.

[0032] In a preferred case, the first wire clamping part 60 is arranged on the sliding table 41. The sliding table 41 can slide along the length direction of the bolt sleeve 100. The sliding table 41 drives the glass fiber wire to reciprocate along the length direction of the bolt sleeve 100, and uniformly winds the glass fiber wire on the surface of the bolt sleeve. An air-operated scissors 42 is arranged on the sliding table 41, and the air-operated scissors 42 is arranged on the lower side of the first wire clamping part 60. After the wire winding of the previous bolt sleeve is completed, the winding clamp 80 clamps the glass fiber wire. At this time, the air-operated scissors 60 extends to the upper surface of the bolt sleeve 100 to cut off the glass fiber wire, replace the new bolt sleeve, and the winding clamp 80 drives the glass fiber wire to wind and fix on the next bolt sleeve.

[0033] In a preferred case, the support assembly 10 includes a fixed seat 20 and a movable seat 30. The fixed seat 20 is fixedly connected to the frame 1 and a first positioning sleeve 21 is rotatably connected to the fixed seat 20. The movable seat 30 is rotatably connected with a second positioning sleeve 31. The first positioning sleeve 21 and the second positioning sleeve 31 are arranged coaxially relative to each other. Both ends of the bolt sleeve 100 are respectively fixed on the first positioning sleeve 21 and the second positioning sleeve 31, and the first positioning sleeve 21 drives the double-threaded screw 100 to rotate. The movable seat 30 is slidably arranged on the first slide rail 101, which facilitates the replacement of the bolt sleeve. Further, the second positioning sleeve 31 passes through the rotating shaft sleeve 73, and a through hole 871 is arranged on the mounting seat 87, and the rotating shaft sleeve 73 passes through the through hole 871.

[0034] To better illustrate the working method of the present invention, the working steps of the wire feeding device for the bolt sleeve wire winding machine for wind turbine blades are as follows:

[0035] (1) The end of the glass fiber wire sequentially passes through the first wire clamping part 60 and the wire passing hole 47, and is clamped by the winding clamp 80;

[0036] (2) The bolt sleeve 100 is tightly fixed between the first positioning sleeve 21 and the second positioning sleeve 31;

[0037] (3) The winding clamp 80 moves to the middle of the bolt sleeve 100 and rotates clockwise to wind the end of the glass fiber wire on the bolt sleeve 100;

[0038] (4) The winding clamp 80 retracts, and the sliding table 41 moves in the same direction. At the same time, the bolt sleeve 100 rotates clockwise to wind the wire and press the glass fiber wire wound by the previous wire clamp 80. Then the winding clamp 80 releases the glass fiber wire and resets, and the bolt sleeve 100 starts to rotate quickly to wind the wire;

[0039] (5) After the wire winding is completed, the bolt sleeve 100 stops rotating, and the sliding table 41 stops at the middle position of the bolt sleeve 100;

[0040] (6) The first wire clamping part 60 presses down to clamp the fiberglass filament. The winding clamp 80 rotates counterclockwise, causing the fixed clamp 82 to pick and press the fiberglass filament to the lower side of the fixed clamp 82. The movable clamp 83 lifts and closes to clamp the fiberglass filament.

[0041] (7) The pneumatic scissors 42 extend to cut the fiberglass filament between the winding clamp 80 and the bolt sleeve 100 and then reset.

[0042] (8) Repeat the process of the above (2) to (7) to wind the next bolt sleeve.
