Description

Technical Field

[0001] The invention relates to the technical field of wire take-up machines, and in particular to a double-drum wire take-up machine for steel stranded wires. Background Art

[0002] After a series of production processes, the steel strand will eventually be wound on the I-shaped wheel by the wire take-up machine, which is the last production process. When the steel strand on the I-shaped wheel reaches a certain length, it is necessary to cut the steel strand, remove the I-shaped wheel, and replace and install a new I-shaped wheel. During the replacement of the new I-shaped wheel, the transportation of the steel strand must be suspended to prevent the steel strand from continuing to be transported backward. Therefore, the production equipment before the wire take-up machine must be shut down. After the I-shaped wheel is installed on the wire take-up machine, all production equipment can be started again, and then the production line can be operated again. In this way, the continuous transportation of the steel strand cannot be achieved, which will reduce the production efficiency of the steel strand and affect the quality of the steel strand.

By using the wire accumulation mechanism of the spindle device, the wire take-up machine can be replaced with a spool without stopping, greatly improving product quality and product manufacturing efficiency. However, it should be noted that the operation of the entire device needs to be controlled by two power motors and pneumatic brakes, which occupies a large space, wastes electricity, and has a high cost.

DETAILED DESCRIPTION

[0034] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings: like Figure 1 to Figure 17As shown, a double-drum wire-winding machine for steel strands includes a frame 1 and a wire-winding system arranged on the frame 1. The number of wire-winding systems is at least one, and here there are two wire-winding systems, that is, two wire-winding systems are installed on the frame 1. The wire-winding system includes a wire collecting device 2, a wire arranging device 3, and a wire-winding device 4 arranged in sequence from top to bottom. The steel strands are wound around the wire collecting device 2 and the wire arranging device 3 in sequence and then wound around the wire-winding device 4. The wire collecting device 2 realizes the function of replacing the I-shaped wheel without stopping the machine, that is, when the I-shaped wheel is replaced by the wire-winding device 4, the steel strands can be wound continuously without stopping, such as Figure 1 and Figure 2 shown.

[0035] The wire collecting device 2 includes a wire wheel 1 5, a wire wheel 2 6, a drum seat 7, a drum shaft 9 controlled by a reduction motor 8, an inner drum 10, a brake cylinder 11, an outer drum 12, and a telescopic ejection assembly 13. The wire wheel 1 5 and the wire wheel 2 6 are arranged on the top of the frame 1. Both the wire wheel 1 5 and the wire wheel 2 6 are V-groove wheels for guiding the steel strands into the wire collecting device 2.

[0036] The frame 1 is also provided with a reduction motor 8 and a reel seat 7. A reel shaft 9 is rotatably provided on the reel seat 7. The reel shaft 9 is rotatably connected to the reel seat 7 through a bearing 14. Both ends of the reel shaft 9 extend outward from the reel seat 7. The axes of the reel shaft 9, the wire passing wheel 1 5 and the wire passing wheel 2 6 are parallel to each other. The reduction motor 8 is arranged on one side of the reel seat 7. The reduction motor 8 includes a wire collecting motor 81 and a reducer 82. The wire collecting motor 81 and the reducer 82 are driven by input shafts, thereby transmitting power to the reducer 82. One end of the reel shaft 9 penetrates into the reducer 82. The reel shaft 9 and the reducer 82 are key-connected, and then the reduction motor 8 can drive the reel shaft 9 to operate, and the reduction motor 8 can control the operating direction of the reel shaft 9.

[0037] The reel shaft 9 is provided with an inner reel 10, a brake cylinder 11 and an outer reel 12 in sequence, and the inner reel 10, the brake cylinder 11 and the outer reel 12 are arranged on the other side of the reel seat 7, and the distances between the inner reel 10, the brake cylinder 11 and the outer reel 12 and the reel seat 7 are increased in sequence. The cross-sections of the inner reel 10 and the outer reel 12 are both in the shape of "]", and the opening directions of the inner reel 10 and the outer reel 12 are consistent and both face the reel seat 7, as shown in FIG. Figure 3 and Figure 4 shown.

[0038] When the inner drum 10 is installed, the inner drum 10 is fixedly connected to the drum shaft 9, that is, the middle part of the inner drum 10 is fixedly connected to the drum shaft 9, and the brake cylinder 11 and the outer drum 12 are both rotatably connected to the drum shaft 9. The middle part of the outer drum 12 is rotatably connected to the drum shaft 9 through the second bearing 15, and the brake cylinder 11 is arranged between the inner drum 10 and the outer drum 12. The cross section of the brake cylinder 11 is an "I" shape, and the middle part of the brake cylinder 11 is rotatably connected to the drum shaft 9 through the third bearing 16. In this way, the drum shaft 9 can drive the inner drum 10 to operate synchronously, and the drum shaft 9 does not affect the state of the brake cylinder 11 and the outer drum 12 during operation.

[0039] The frame 1 is provided with an ejector assembly 13 for limiting the rotation of the brake cylinder 11. The ejector assembly 13 is a pneumatic telescopic structure. Specifically, the ejector assembly 13 includes an ejector cylinder and an ejector rod controlled by the ejector cylinder. The ejector rod is slidably arranged on the frame 1, and the axes of the ejector rod and the drum shaft 9 are parallel to each other. In order to achieve the cooperation between the brake cylinder 11 and the ejector assembly 13, a limit plate 17 is arranged on the outer wall of the brake cylinder 11. When the ejector assembly 13 is extended, the limit plate 17 abuts against the ejector rod, which can limit the rotation of the brake cylinder 11.

[0040] A corner guide wheel 18 is arranged on the outer wall of the brake cylinder 11, and the plate body of the limiting plate 17 and the wheel body of the corner guide wheel 18 are tangent to the outer wall of the brake cylinder 11, forming an inclined state. Specifically, one of the side surfaces of the plate body of the limiting plate 17 is inclined close to the outer wall of the brake cylinder 11, and one of the side surfaces of the wheel body of the corner guide wheel 18 is also inclined close to the outer wall of the brake cylinder 11. The horizontal diameter of the wheel body of the corner guide wheel 18 is parallel to the reel axis 9, and the two ends of the horizontal diameter of the wheel body of the corner guide wheel 18 are respectively close to the inner reel 10 and the outer reel 12.

[0041] The plate body of the limit plate 17 and the wheel body of the corner guide wheel 18 are inclined in the same direction, and the connection points between the limit plate 17 and the brake cylinder 11 and the connection points between the corner guide wheel 18 and the brake cylinder 11 are respectively located at the two ends of the diameter of the brake cylinder 11. The corner guide wheel 18 can rotate by itself, and the corner guide wheel 18 can rotate driven by the brake cylinder 11. The steel strand wound on the inner drum 10 can be guided to the outer drum 12 through the corner guide wheel 18 and wound.

[0042] The steel strand is wound around the wire wheel 1 5, the wire wheel 2 6, the inner drum 10, the corner guide wheel 18, the outer drum 12 and the wire arrangement device 3 in sequence, and then wound around the wire take-up device 4. Specifically, after the steel strand is wound around the wire wheel 1 5 and the wire wheel 2 6, it is wound around the inner drum 10, and then it is wound around the corner guide wheel 18 and then wound around the outer drum 12. The steel strand is led out from the outer drum 12, wound downward through the wire arrangement device 3, and then wound around the wire take-up device 4.

[0043] In order to achieve the linkage control of the inner reel 10 and the brake cylinder 11, that is, to achieve the synchronous operation of the inner reel 10 and the brake cylinder 11, an oil passage 19 is opened in the reel shaft 9. The cross-section of the oil passage 19 is "T"-shaped, and one end of the oil passage 19 is arranged axially along the reel shaft 9, and the other end of the oil passage 19 extends to the reel shaft 9 where the inner reel 10 is located, and radially penetrates both sides of the reel shaft 9.

[0044] One end of the drum shaft 9 is connected to a rotary joint 20 connected to the oil passage 19. Specifically, the end of the drum shaft 9 is connected to the rotary joint 20 after extending out of the reducer 82. The rotary joint 20 is fixed in position and does not affect the rotation of the drum shaft 9. It can also realize the delivery of hydraulic oil. The oil passage 19 is connected to a hydraulic pump through the rotary joint 20. The hydraulic pump is not shown in the figure. The operation of the hydraulic pump can supply hydraulic oil of a certain pressure to the oil passage 19.

[0045] The two ends of the oil passage 19 radially penetrating the two sides of the reel shaft 9 are connected to an oil pipe 21 respectively, that is, the other ends of the oil passage 19 are connected to two oil pipes 21 respectively, and the oil pipes 21 are arranged in the inner reel 10. An oil storage ring 22 is arranged on the end surface of the inner reel 10 facing the brake cylinder 11. The oil storage ring 22 is an annular body with a groove, and the groove space can store oil; at the same time, an oil storage ring cover 23 is slidably arranged on the oil storage ring 22, and the sliding direction of the oil storage ring cover 23 is consistent with the axial direction of the reel shaft 9, that is, the oil storage ring cover 23 is arranged at the opening of the groove of the oil storage ring 22, and the oil storage ring cover 23 can close the opening of the oil storage ring 22. In this way, the oil storage ring 22 and the oil storage ring cover 23 are enclosed to form a closed oil chamber 24. Since the oil storage ring cover 23 is slidable, the size of the oil chamber 24 is adjustable, such as Figure 5 , 6 and Figure 7 shown.

[0046] The oil chamber 24 is connected to the oil pipe 21, that is, the oil chamber 24 is connected to the oil passage 19 through two oil pipes 21. In this way, the hydraulic oil pumped into the oil passage 19 can be introduced into the oil chamber 24 through the oil pipe 21, thereby controlling the left and right sliding of the oil storage ring cover 23. A plurality of groups of guide rods 37 evenly distributed in the annular direction are arranged in the oil storage ring cover 23, and the number of each group of guide rods 37 is two. The guide rods 37 penetrate into the oil storage ring 22 and are slidably arranged with the oil storage ring 22. In this way, the oil storage ring cover 23 can be prevented from rotating in a circle, and the oil storage ring 22 and the oil storage ring cover 23 can be prevented from rotating relative to each other.

[0047] A friction ring 25 is arranged on the end surface of the brake cylinder 11. When the friction ring 25 is installed, a mounting ring 26 is arranged on the end surface of the brake cylinder 11. The friction ring 25 is arranged on the mounting ring 26. The oil storage ring cover 23 is movably arranged between the friction ring 25 and the oil storage ring 22. The movably arranged oil storage ring cover 23 is positionally variable, and the end surface of the oil storage ring cover 23 is in corresponding contact with the friction ring 25. After the ejection assembly 13 does not restrict the brake cylinder 11, hydraulic oil is filled into the oil chamber 24, and then the hydraulic oil pushes the oil storage ring cover 23 to be in close contact with the friction ring 25. In this way, the inner reel 10 can drive the brake cylinder 11 to operate synchronously.

[0048] The principle of the above wire collecting device 2 is as follows: after the steel strands are wound around the wire wheel 1 5 and the wire wheel 2 6, they are wound several times on the inner drum 10, and then led out to pass around the corner guide wheel 18, and then wound several times on the outer drum 12, and then led out to pass through the wire arrangement device 3, and finally wound on the I-shaped wheel of the take-up device 4. Under normal operating conditions, the reduction motor 8 drives the inner drum 10 to rotate counterclockwise, and after the steel strands are wound several times, they are wound around the inner drum 10 and wound around the corner guide wheel 18 to the outer drum 12, and the ejection assembly 13 is extended to block the rotation of the brake drum 11, so that the brake drum 11 does not rotate, and the outer drum 12 rotates clockwise due to the force of the take-up device 4 winding and pulling the steel strands.

[0049] When the steel strand wound on the take-up device 4 reaches a certain length and the I-shaped wheel needs to be replaced, the take-up device 4 and the wire arrangement device 3 both stop running, the steel strand between the take-up device 4 and the wire arrangement device 3 is cut off, and the wire arrangement device 3 is used to clamp the cut end of the steel strand led out of the outer drum 12 to achieve temporary fixation, and the I-shaped wheel can be replaced at this time. At the same time, the ejection assembly 13 retracts and no longer restricts the brake cylinder 11, and the hydraulic pump pumps hydraulic oil into the oil chamber 24, causing the oil storage ring cover 23 and the friction ring 25 to be in close contact, and then the inner drum 10 and the brake cylinder 11 operate together, and the steel strand is wound around the inner drum 10 and the outer drum 12 in circles. At this time, since the take-up device 4 is in a stopped state and no longer pulls the steel strand downward, the wire arrangement device 3 clamps the cut end of the steel strand led out of the outer drum 12 to achieve temporary fixation, and then the outer drum 12 stops running. It can be seen that the steel strand does not stop running, but is temporarily wound around the inner drum 10 and the outer drum 12 .

[0050] When the take-up device 4 completes the replacement of the I-shaped wheel, it no longer clamps the steel strand and continues to pull the steel strand through the take-up device 4. At this time, the steel strand pulls the outer drum 12 to rotate at high speed. At the same time, the hydraulic oil is controlled to exit the oil chamber 24, and the oil storage ring cover 23 is not in close contact with the friction ring 25. The steel strand pulls the outer drum 12 and the brake drum 11 to run in the same direction. At this time, the direction of the brake drum 11 is opposite to that of the inner drum 10, and the speed of the brake drum 11 is less than that of the outer drum 12, thereby releasing the steel strand accumulated during the replacement of the I-shaped wheel. Then the ejection assembly 13 extends to limit the rotation of the brake drum 11 again, and the take-up device 4 returns to the normal take-up speed, and then the outer drum 12 operates normally. The wire collecting device 2 can realize the replacement of the I-shaped wheel without stopping the machine, thereby improving the production efficiency of the steel strand.

[0051] In order to optimize the product, the steel strands drawn out through the wire wheel 2 6 can be introduced from the end of the inner drum 10, so as to facilitate the uniform arrangement of the steel strands on the inner drum 10. A limit assembly 38 is provided on the frame 1. The limit assembly 38, the wire wheel 1 5, the wire wheel 2 6, and the inner drum 10 are on the same side of the frame 1. The limit assembly 38 is arranged between the wire wheel 2 6 and the inner drum 10. The limit assembly 38 corresponds to the end of the inner drum 10 connected to the drum seat 7. The limit assembly 38 includes a limit seat 381 with a "T"-shaped cross section and a limit roller 1 382 rotatably arranged on the limit seat 381. One end of the limit roller 1 382 is vertically installed at the end of the limit seat 381 away from the frame 1, and the axial direction of the limit roller 1 382 faces the end of the inner drum 10 close to the drum seat 7. As a result, after the steel strand is wound around the wire wheel 2 6, it contacts the limiting roller 1 382 near the side wall of the frame 1, and then is introduced through the end of the inner drum 10 connected to the drum seat 7 and wound on the inner drum 10. The limiting roller 1 382 can limit the introduction position of the steel strand on the inner drum 10, and the introduction position is at the end of the inner drum 10 near the drum seat 7 to avoid the introduction position from shifting back and forth.

[0052] The steel strand will shake during operation due to poor cable arrangement. If the position of the limit roller 382 is fixed, the steel strand will break. Here, the limit roller 382 needs to be able to swing to a certain extent, so as to tighten the steel strand, avoid the breakage caused by shaking, and ensure the tension of the inner reel 10. Specifically, a single bolt 39 is movably inserted into the bosses on both sides of the limit seat 381. The tail end of the single bolt 39 is threadedly connected to the frame 1 through the limit seat 381. The single bolt 39 passes through the frame 1 and is connected to the nut, which can better ensure the reliability of the installation of the single bolt 39. The limiting seat 381 is supported by two single bolts 39, and the limiting seat 381 can slide back and forth on the single bolts 39. The single bolts 39 are sleeved with a single compression spring 40 located between the boss of the limiting seat 381 and the head end of the single bolt 39, so that the limiting seat 381 can elastically slide on the single bolt 39, so that the limiting roller 1 382 can slide away from the reel seat 7 or close to the reel seat 7, thereby changing the position of the limiting roller 1 382. The adjustment of the position of the limiting roller 1 382 can balance the winding force of the steel strand, ensure the best tension of the steel strand, and avoid damage to the wire.

[0053] When installing the corner guide wheel 18 , a wheel mounting plate 41 is arranged on the outer wall of the brake cylinder 11 , and the corner guide wheel 18 is rotatably arranged on the wheel mounting plate 41 . The diameter of the corner guide wheel 18 is greater than the axial length of the brake cylinder 11 . In the process of the steel strand passing through the corner guide wheel 18, in order to prevent the steel strand from falling off the wheel, an anti-slip plate 42 is fixedly connected to the wheel mounting plate 41, and the anti-slip plate 42 is located between the wheel mounting plate 41 and the corner guide wheel 18. The anti-slip plate 42 is an integrated structure composed of two strip plates connected in a V shape. The center of the V-shaped top of the anti-slip plate 42 and the center of the corner guide wheel 18 are on the same axis, and the V-shaped angle of the anti-slip plate 42 is 120°-160°. The two strip plates of the anti-slip plate 42 extend radially along the corner guide wheel 18 respectively, and the two strip plate ends of the anti-slip plate 42 protrude from the edge of the corner guide wheel 18. The two strip plate ends of the anti-slip plate 42 are rotatably provided with anti-slip wheels 43 tangent to the corner guide wheel 18, and the two anti-slip wheels 43 correspond to the two end positions of the axial direction of the brake cylinder 11 respectively. The thickness of the anti-slip wheel 43 is greater than that of the corner guide wheel 18 . The anti-slip wheel 43 cooperates with the corner guide wheel 18 to limit the passing steel strands and prevent the steel strands from escaping from the corner guide wheel 18 .

[0054] At the same time, in the process of the steel strand winding out of the corner guide wheel 18 and winding into the outer drum 12, in order to ensure that the steel strand can be introduced from one end of the outer drum 12 and facilitate the uniform arrangement of the steel strand on the outer drum 12, a limit rod 44 of a plate structure is provided on one of the two strip plates close to the outer drum 12, and the limit rod 44 extends longitudinally toward the outer drum 12, and the limit rod 44 points to the end of the outer drum 12 close to the brake cylinder 11. A limit roller 2 45 is provided at the longitudinally extending end of the limit rod 44, and after the steel strand is wound out of the corner guide wheel 18, it contacts a side wall of the limit roller 2 45 close to the corner guide wheel 18, and then is introduced from one end of the outer drum 12 and wound on the outer drum 12, so as to prevent the introduction position of the steel strand on the outer drum 12 from being offset.

When the resisting spring 49 is in a balanced state, the limit upper rod 441 and the limit lower rod 442 are arranged in a straight line. When the steel strand passes through the limiting roller 45, the limiting roller 45 can be caused to swing according to the state of the steel strand to balance the wire-winding force of the steel strand, thereby ensuring the best tension of the steel strand and avoiding damage to the wire.

[0056] In this embodiment, the wire arrangement device 3 ensures that the steel strands can be evenly arranged on the take-up I-shaped wheel 31 of the take-up device 4.
