Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a double-drum winding machine for steel strand. Background Technology

[0002] After a series of production processes, the steel strand is finally wound onto a reel by a take-up machine, which is the final production step. Once the steel strand on the reel reaches a certain length, it needs to be cut, the reel removed, and a new reel installed. During this replacement process, the steel strand feeding must be paused to prevent further feeding. Therefore, all upstream production equipment must be shut down until the reel is installed on the take-up machine before all equipment is restarted and the production line resumes operation. This disrupts the continuous feeding of the steel strand, reducing production efficiency and affecting the quality of the steel strand.

[0003] In response, patent publication number CN216662030U discloses a main shaft device for a double-drum wire accumulation mechanism. By using the wire accumulation mechanism of this main shaft device, the take-up machine can be changed without stopping, significantly improving product quality and manufacturing efficiency. However, it should be noted that the operation of the entire device relies on two power motors and a pneumatic brake for control, which occupies a large space, wastes electrical energy, and has a high cost. Summary of the Invention

[0004] This invention addresses the problem that conventional winding machines require the shutdown of upstream production equipment when changing I-beams. It provides a double-drum winding machine for steel strands, which allows for I-beam replacement without stopping the production line, thereby improving production efficiency, reducing energy consumption, and saving costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A double-drum take-up machine for steel strand includes a frame and a take-up system mounted on the frame. The take-up system includes a wire collecting device, a wire feeding device, and a take-up device arranged sequentially from top to bottom.

[0007] The wire collecting device includes a first wire guide wheel, a second wire guide wheel, a drum seat, a drum shaft controlled by a reduction motor, an inner drum, a brake drum, an outer drum, and a telescopic ejection assembly. The first and second wire guide wheels are arranged on the top of the frame to facilitate guiding the steel strands into the wire collecting device. The reduction motor and the drum seat are also provided on the frame.

[0008] The drum shaft is rotatably mounted on the drum seat. The axes of the drum shaft, the first guide wheel, and the second guide wheel are parallel to each other. The inner drum, the brake drum, and the outer drum are sequentially threaded onto the drum shaft. The inner drum and the drum shaft are connected and fixed, and the two run synchronously. The brake drum and the outer drum are both rotatably connected to the drum shaft.

[0009] The frame is provided with the ejection assembly for limiting the rotation of the brake cylinder. An angle guide wheel is provided on the outer wall of the brake cylinder. The steel strand is wound around the first wire wheel, the second wire wheel, the inner drum, the angle guide wheel, the outer drum and the wire winding device in sequence and then wound onto the take-up device.

[0010] The drum shaft has an oil passage inside. One end of the drum shaft is connected to a rotary joint that connects to the oil passage, which does not affect the operation of the drum shaft and can ensure the delivery of oil. The other end of the oil passage radially passes through the drum shaft and is connected to an oil pipe. The oil pipe is arranged in the inner drum. An oil reservoir ring is provided on the end face of the inner drum facing the brake cylinder. An oil reservoir ring cover is slidably provided on the oil reservoir ring. The oil reservoir ring and the oil reservoir ring cover together form an oil cavity. The amount of hydraulic oil in the oil cavity can control the sliding of the oil reservoir ring cover. The oil cavity is connected to the oil pipe. A friction ring is provided on the end face of the brake cylinder. The end face of the oil reservoir ring cover is in corresponding contact with the friction ring, which facilitates the inner drum to drive the brake cylinder to run together.

[0011] Furthermore, the geared motor is arranged on one side of the drum seat, and the inner drum, brake drum, and outer drum are all arranged on the other side of the drum seat; the geared motor includes a wire collecting motor and a reducer, the wire collecting motor and the reducer are driven by the input shaft, one end of the drum shaft is inserted into the reducer, the drum shaft and the reducer are keyed to facilitate the rotation of the drum shaft, and the end of the drum shaft extends out of the reducer and is connected to the rotary joint.

[0012] Furthermore, a limiting plate is provided on the outer wall of the brake cylinder; the ejection assembly includes an ejection cylinder and an ejection rod controlled by the ejection cylinder. The ejection rod is slidably mounted on the frame. The axes of the ejection rod and the drum shaft are parallel to each other. When the ejection rod slides out, the limiting plate abuts against the ejection rod to facilitate limiting the rotation of the brake cylinder.

[0013] Furthermore, after the steel strand passes over the first and second wire rollers, it is wound onto the inner drum, then around the corner guide roller, and finally wound onto the outer drum. The steel strand is led out from the outer drum, wound downwards through the wire laying device, and then wound onto the take-up device.

[0014] Furthermore, the distance between the inner drum, the brake drum, and the outer drum and the drum seat increases sequentially. The cross-sections of the inner drum and the outer drum are both in the shape of "]". The opening directions of the inner drum and the outer drum are consistent and both face the drum seat. The middle part of the inner drum is fixedly connected to the drum shaft, and the middle part of the outer drum is rotatably connected to the drum shaft.

[0015] The brake cylinder is arranged between the inner and outer drums. The brake cylinder has an "I" shaped cross-section and is rotatably connected to the drum shaft in the middle.

[0016] Furthermore, the oil passage has a "T" shaped cross section. One end of the oil passage is arranged along the axial direction of the drum shaft and connected to the rotary joint. The other end of the oil passage extends to the position of the drum shaft where the inner drum is located, and then radially penetrates both sides of the drum shaft, and then connects to one of the oil pipes on each side.

[0017] The oil storage ring is an annular body with a groove to facilitate the storage of oil. The oil storage ring cover is arranged at the opening of the groove of the oil storage ring to facilitate the sealing of the oil storage ring. The sliding direction of the oil storage ring cover is consistent with the axial direction of the drum shaft. The oil chamber is connected to the oil passage through two oil pipes, and the oil passage is connected to the hydraulic pump through a rotary joint.

[0018] A mounting ring is provided on the end face of the brake cylinder, and the friction ring is arranged on the mounting ring. An oil reservoir cover is movably arranged between the friction ring and the oil reservoir ring.

[0019] Furthermore, the wire laying device includes a synchronous belt module and a wire laying wheel assembly controlled by the synchronous belt module, which facilitates the uniform laying of steel strands.

[0020] Furthermore, the take-up device includes a take-up motor, an active clamping assembly, a passive clamping assembly, and a lifting seat. The take-up motor and the active clamping assembly are chain-driven. The active clamping assembly and the passive clamping assembly are arranged coaxially from left to right. A take-up I-beam is clamped between the active clamping assembly and the passive clamping assembly, which facilitates the rotation of the take-up I-beam. The frame is slidably equipped with a lifting seat for raising and lowering the take-up I-beam. The lifting seat is arranged between the active clamping assembly and the passive clamping assembly. The lifting seat facilitates the raising and lowering of the take-up I-beam, and allows for the disassembly and replacement of the take-up I-beam.

[0021] Furthermore, the plate body of the limiting plate and the wheel body of the corner guide wheel are both tangent to the outer wall of the brake cylinder, forming an inclined state. The inclined directions of the plate body of the limiting plate and the wheel body of the corner guide wheel are the same. The connection point between the limiting plate and the brake cylinder and the connection point between the corner guide wheel and the brake cylinder are respectively located at both ends of the brake cylinder diameter.

[0022] The beneficial effects of this utility model through the above technical solution are:

[0023] This utility model features a reasonable structural design. The steel strand is sequentially wound around the wire collecting device, the wire laying device, and the take-up device. Particularly noteworthy is the wire collecting device, where the steel strand first winds several turns on the inner drum, then is led out, passes around the corner guide wheel, winds onto the outer drum, winds several more turns, and finally winds into the wire laying device. Therefore, when changing the I-beam, controlling the rotation of the brake cylinder allows the steel strand to be temporarily wound around the inner and outer drums, enabling continuous I-beam replacement without stopping the machine. During this replacement process, the steel strand continues to run on the wire collecting device, preventing the entire production line from stopping and improving production efficiency.

[0024] The wire-laying device of this invention uses a synchronous belt module to drive the wire-laying wheel assembly to move linearly and reciprocally, thereby evenly distributing the steel strand on the take-up device. The wire-laying wheel assembly has guiding and clamping functions; during the replacement of the take-up reel, the components in the wire-laying wheel assembly can clamp and fix the steel strand. The take-up device is driven by a take-up motor to operate the active clamping assembly, which, in conjunction with the passive clamping assembly, fixes the take-up reel and drives its rotation, thus realizing the take-up operation. The lifting seat facilitates the raising and lowering of the take-up reel, thereby facilitating the disassembly and replacement of the take-up reel. Attached Figure Description

Detailed Implementation

[0043] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0044] like Figures 1-17 As shown, the double-drum take-up machine for steel strand includes a frame 1 and a take-up system mounted on the frame 1. The take-up system has at least one component, but here there are two, meaning two take-up systems are installed on the frame 1. Each take-up system includes a wire collecting device 2, a wire guiding device 3, and a take-up device 4, arranged sequentially from top to bottom. The steel strand passes through the wire collecting device 2 and the wire guiding device 3 before being wound onto the take-up device 4. The wire collecting device 2 enables the replacement of the I-beam without stopping the machine; that is, when the take-up device 4 is changing the I-beam, the steel strand can continue to wind without stopping. Figure 1 and Figure 2 As shown.

[0045] The wire collecting device 2 includes a first wire guide wheel 5, a second wire guide wheel 6, a drum seat 7, a drum shaft 9 controlled by a geared motor 8, an inner drum 10, a brake cylinder 11, an outer drum 12, and an ejection assembly 13 with a telescopic structure. The first wire guide wheel 5 and the second wire guide wheel 6 are arranged on the top of the frame 1. Both the first wire guide wheel 5 and the second wire guide wheel 6 are V-grooved wheels used to guide the steel strands into the wire collecting device 2.

[0046] The frame 1 is also equipped with a geared motor 8 and a drum seat 7. A drum shaft 9 is rotatably mounted on the drum seat 7. The drum shaft 9 is rotatably connected to the drum seat 7 via a bearing 14. Both ends of the drum shaft 9 extend outward from the drum seat 7. The axes of the drum shaft 9, the first guide roller 5, and the second guide roller 6 are parallel to each other. The geared motor 8 is arranged on one side of the drum seat 7. The geared motor 8 includes a yarn collecting motor 81 and a reducer 82. The input shafts of the yarn collecting motor 81 and the reducer 82 are belt driven, thereby transmitting power to the reducer 82. One end of the drum shaft 9 passes through the reducer 82. The drum shaft 9 and the reducer 82 are keyed together, so the geared motor 8 can drive the drum shaft 9 to rotate. At the same time, the geared motor 8 can control the rotation direction of the drum shaft 9.

[0047] An inner drum 10, a brake drum 11, and an outer drum 12 are sequentially threaded onto the drum shaft 9. The inner drum 10, brake drum 11, and outer drum 12 are all located on the other side of the drum base 7, and the distances between the inner drum 10, brake drum 11, and outer drum 12 and the drum base 7 increase sequentially. Both the inner drum 10 and outer drum 12 have a "]" shaped cross-section, and their openings face the same direction and both face the drum base 7. Figure 3 and Figure 4 As shown.

[0048] During installation, the inner drum 10 is fixedly connected to the drum shaft 9, meaning the middle part of the inner drum 10 is fixedly connected to the drum shaft 9. 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 via bearing 15. A brake cylinder 11, with an "I"-shaped cross-section, is positioned between the inner drum 10 and the outer drum 12. The middle part of the brake cylinder 11 is rotatably connected to the drum shaft 9 via bearing 16. In this way, the drum shaft 9 can drive the inner drum 10 to rotate synchronously, and the rotation of the drum shaft 9 does not affect the state of the brake cylinder 11 and the outer drum 12.

[0049] The frame 1 is equipped 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 mounted 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 provided on the outer wall of the brake cylinder 11. When the ejector assembly 13 extends, the limit plate 17 abuts against the ejector rod, thereby limiting the rotation of the brake cylinder 11.

[0050] An angle guide wheel 18 is provided on the outer wall of the brake cylinder 11. The plate body of the limiting plate 17 and the wheel body of the angle guide wheel 18 are both tangent to the outer wall of the brake cylinder 11, forming an inclined state. Specifically, one side of the plate body of the limiting plate 17 is inclined close to the outer wall of the brake cylinder 11, and one side of the wheel body of the angle guide wheel 18 is also inclined close to the outer wall of the brake cylinder 11. The diameter of the wheel body of the angle guide wheel 18 in the horizontal direction is parallel to the drum shaft 9. The two ends of the diameter of the wheel body of the angle guide wheel 18 in the horizontal direction are close to the inner drum 10 and the outer drum 12, respectively.

[0051] The limiting plate 17 and the angle guide wheel 18 are inclined in the same direction. The connection point between the limiting plate 17 and the brake cylinder 11 and the connection point between the angle guide wheel 18 and the brake cylinder 11 are located at opposite ends of the diameter of the brake cylinder 11. The angle guide wheel 18 can rotate on its own and can also rotate under the drive of the brake cylinder 11. The steel strand wound on the inner drum 10 can be guided to the outer drum 12 and wound through the angle guide wheel 18.

[0052] The steel strand is wound sequentially around the first wire wheel 5, the second wire wheel 6, the inner drum 10, the corner guide wheel 18, the outer drum 12, and the wire laying device 3 before being wound onto the take-up device 4. Specifically, after passing over the first wire wheel 5 and the second wire wheel 6, the steel strand is wound onto the inner drum 10, then around the corner guide wheel 18, and finally onto the outer drum 12. The steel strand is then led out from the outer drum 12, wound downwards through the wire laying device 3, and finally wound onto the take-up device 4.

[0053] In order to achieve the linkage control of the inner drum 10 and the brake cylinder 11, that is, to achieve the synchronous operation of the inner drum 10 and the brake cylinder 11, an oil passage 19 is provided in the drum shaft 9. The oil passage 19 has a "T" shaped cross section. One end of the oil passage 19 is arranged along the axial direction of the drum shaft 9, and the other end of the oil passage 19 extends to the position of the drum shaft 9 where the inner drum 10 is located, and then radially penetrates both sides of the drum shaft 9.

[0054] One end of the drum shaft 9 is connected to a rotary joint 20 that connects to the oil passage 19. Specifically, the rotary joint 20 is connected to the end of the drum shaft 9 after it extends out of the reducer 82. The rotary joint 20 is fixed in position and does not affect the rotation of the drum shaft 9, and it can 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 at a certain pressure into the oil passage 19.

[0055] Each end of the oil passage 19, which radially penetrates both sides of the drum shaft 9, is connected to an oil pipe 21, meaning that the other end of the oil passage 19 is connected to two oil pipes 21 respectively. The oil pipes 21 are arranged in the inner drum 10. An oil reservoir ring 22 is provided on the end face of the inner drum 10 facing the brake cylinder 11. The oil reservoir ring 22 is an annular body with a groove, and the groove space can store oil. At the same time, an oil reservoir ring cover 23 is slidably arranged on the oil reservoir ring 22. The sliding direction of the oil reservoir ring cover 23 is consistent with the axial direction of the drum shaft 9, that is, the oil reservoir ring cover 23 is arranged at the groove opening of the oil reservoir ring 22. The oil reservoir ring cover 23 can close the opening of the oil reservoir ring 22. In this way, the oil reservoir ring 22 and the oil reservoir ring cover 23 together form a closed oil cavity 24. Since the oil reservoir ring cover 23 is slidable, the size of the oil cavity 24 is adjustable. Figure 5 , 6 and Figure 7 As shown.

[0056] The oil chamber 24 is connected to the oil pipe 21, meaning the oil chamber 24 is connected to the oil passage 19 via two oil pipes 21. This allows hydraulic oil pumped into the oil passage 19 to be introduced into the oil chamber 24 through the oil pipes 21, thereby controlling the left and right sliding of the oil reservoir ring cover 23. The oil reservoir ring cover 23 is equipped with multiple sets of circumferentially distributed guide rods 37, with two guide rods in each set. The guide rods 37 insert into the oil reservoir ring 22 and slide alongside it, thus preventing circumferential rotation of the oil reservoir ring cover 23 and preventing relative rotation between the oil reservoir ring 22 and the oil reservoir ring cover 23.

[0057] A friction ring 25 is provided on the end face of the brake cylinder 11. During installation, a mounting ring 26 is provided on the end face of the brake cylinder 11, and the friction ring 25 is arranged on the mounting ring 26. An oil reservoir cover 23 is movably arranged between the friction ring 25 and the oil reservoir ring 22. The movable arrangement means that the position of the oil reservoir cover 23 is variable, and the end face of the oil reservoir cover 23 is in corresponding contact with the friction ring 25. After the ejector assembly 13 no longer restricts the brake cylinder 11, hydraulic oil is filled into the oil chamber 24. The hydraulic oil then pushes the oil reservoir cover 23 into close contact with the friction ring 25. In this way, the inner drum 10 can drive the brake cylinder 11 to rotate synchronously.

[0058] The principle of the above-mentioned wire collecting device 2 is as follows: After the steel strand passes over the first wire guide wheel 5 and the second wire guide wheel 6, it is wound several times on the inner drum 10, then led out and passed over the corner guide wheel 18, wound several times on the outer drum 12, then led out and passed through the wire laying device 3, and finally wound onto the H-beam of the take-up device 4. Under normal operating conditions, the reduction motor 8 drives the inner drum 10 to rotate counterclockwise. After the steel strand is wound several times, it is wound out of the inner drum 10 and wound onto the outer drum 12 by the corner guide wheel 18. The push-out component 13 extends and blocks the rotation of the brake cylinder 11, so the brake cylinder 11 does not rotate. Under the force of the take-up device 4 winding and pulling the steel strand, the outer drum 12 rotates clockwise.

[0059] When the steel strand wound on the take-up device 4 reaches a certain length and the I-beam needs to be replaced, both the take-up device 4 and the wire-laying device 3 stop operating, cutting the steel strand between them. The wire-laying device 3 then clamps the cut end of the steel strand leading out of the outer drum 12, temporarily fixing it in place. At this point, the I-beam can be replaced. Simultaneously, the ejector assembly 13 retracts, no longer restricting the brake cylinder 11. The hydraulic pump pumps hydraulic oil into the oil chamber 24, causing the oil reservoir cover 23 and the friction ring 25 to come into close contact. Consequently, the inner drum 10 and the brake cylinder 11 rotate together, and the steel strand winds around the inner drum 10 and the outer drum 12. Since the take-up device 4 is stopped and no longer pulls the steel strand downwards, the wire-laying device 3 clamps the cut end of the steel strand leading out of the outer drum 12, temporarily fixing it in place. The outer drum 12 then stops operating. It can be seen that the steel strand has not stopped running, but is temporarily wound around the inner drum 10 and the outer drum 12.

[0060] After the take-up device 4 completes the replacement of the I-beam reel, it no longer clamps the steel strand and continues to pull it. At this time, the steel strand pulls the outer drum 12 to rotate at high speed. Simultaneously, the hydraulic oil is controlled to exit the oil chamber 24, and the oil reservoir cover 23 is not in close contact with the friction ring 25. The steel strand pulls the outer drum 12 and the brake cylinder 11 to rotate in the same direction. At this time, the brake cylinder 11 rotates in the opposite direction to the inner drum 10, and the speed of the brake cylinder 11 is less than that of the outer drum 12, thereby releasing the steel strand accumulated during the replacement of the I-beam reel. Then, the ejector assembly 13 extends and restricts the rotation of the brake cylinder 11 again, and the take-up device 4 returns to the normal take-up speed, and the outer drum 12 operates normally. The wire collecting device 2 enables the replacement of the I-beam reel without stopping the machine, improving the production efficiency of steel strand.

[0061] In this embodiment, the wire laying device 3 ensures that the steel strands can be evenly distributed on the take-up reel 31 of the take-up device 4. The wire laying device 3 includes a timing belt module 301a and a wire laying reel assembly 302a controlled by the timing belt module 301a. The timing belt module 301a is prior art and can drive the wire laying reel assembly 302a to move linearly back and forth, such as... Figure 8 and Figure 9 As shown. The cable tray assembly 302a adopts the steel cord reel heavy-duty I-beam reel take-up and cable tray structure locking device disclosed in patent publication number CN102745553B.

[0062] The take-up device 4 includes a take-up motor 27, an active clamping assembly 28, a passive clamping assembly 29, and a lifting seat 30. The take-up motor 27 and the active clamping assembly 28 are chain-driven, providing rotational power to the active clamping assembly 28. The active clamping assembly 28 and the passive clamping assembly 29 are coaxially arranged on the frame 1 with a gap between them, such as... Figure 10As shown. The structure and principle of the active clamping assembly 28 and the passive clamping assembly 29 can be found in a wire take-up machine disclosed in patent publication number CN220216278U.

[0063] A take-up reel 31 is clamped between the active clamping assembly 28 and the passive clamping assembly 29. The take-up reel 31 is suspended in the air during normal operation. To facilitate the loading and unloading of the take-up reel 31, a lifting seat 30 is slidably mounted on the frame 1 for raising and lowering the take-up reel 31. The lifting seat 30 is positioned between the active clamping assembly 28 and the passive clamping assembly 29. The lifting seat 30 has a lifting function, allowing the take-up reel 31 to be raised and installed between the active clamping assembly 28 and the passive clamping assembly 29, or to unload the take-up reel 31 wound with steel strand, allowing it to fall to the ground.

[0064] The lifting seat 30 includes a main lifting cylinder 301, an auxiliary lifting cylinder 302, and a lifting plate 303, such as Figure 11 , 12 and Figure 13 As shown. A main lifting cylinder 301 and an auxiliary lifting cylinder 302 are installed on the frame 1. The main lifting cylinder 301 is inverted with its piston end facing downwards and connected to the lifting plate 303. The auxiliary lifting cylinder 302 is connected to the lifting plate 303 with its piston end facing upwards. Figure 12 As shown. There are two auxiliary lifting cylinders 302, and the line connecting the auxiliary lifting cylinder 302 and the main lifting cylinder 301 forms an isosceles triangle. A lifting plate 303 is arranged between the main lifting cylinder 301 and the auxiliary lifting cylinder 302. The lifting plate 303 can be controlled to rise and fall by the synchronous operation of the main lifting cylinder 301 and the auxiliary lifting cylinder 302.

[0065] Meanwhile, an offset plate 32 is slidably mounted on the lifting plate 303, with its sliding direction aligned with the axial direction of the take-up reel 31. The offset plate 32 rises and falls together with the lifting plate 303. The offset plate 32 supports the take-up reel 31 during assembly and disassembly. After the take-up reel 31 sits on the offset plate 32, the offset plate 32 can move it left and right relative to the lifting plate 303. Rolling elements 33 are provided at both ends of the offset plate 32. Each rolling element 33 includes a roller and bearing rollers at both ends of the roller. The bearing rollers roll along the lifting plate 303. Furthermore, a positioning block 34 is provided on the offset plate 32, and a positioning rod 35 is provided on the lifting plate 303. The positioning block 34 passes through the positioning rod 35, providing guidance for the sliding of the offset plate 32. Compression springs 36 are sleeved on the positioning rods 35 on both sides of the positioning block 34 to keep the offset plate 32 centered.

[0066] To optimize the product and ensure that the steel strand led out by the second wire guide wheel 6 can be introduced from the end of the inner drum 10, facilitating the uniform winding of the steel strand on the inner drum 10, a limiting component 38 is provided on the frame 1. The limiting component 38, the first wire guide wheel 5, the second wire guide wheel 6, and the inner drum 10 are on the same side of the frame 1. The limiting component 38 is arranged between the second wire guide wheel 6 and the inner drum 10, corresponding to the end of the inner drum 10 connected to the drum seat 7. The limiting component 38 includes a limiting seat 381 with a "T"-shaped cross section and a limiting roller 382 rotatably mounted on the limiting seat 381. One end of the limiting roller 382 is vertically mounted on the end of the limiting seat 381 away from the frame 1, and the axial direction of the limiting roller 382 is towards the end of the inner drum 10 near the drum seat 7. As a result, after the steel strand passes through the wire guide wheel 6, it contacts the limiting roller 382 near the side wall of the frame 1. Then, it is introduced and wound onto the inner drum 10 by the end connected to the drum seat 7. The limiting roller 382 can restrict the introduction position of the steel strand on the inner drum 10. The introduction position is at the end of the inner drum 10 near the drum seat 7, which prevents the introduction position from shifting back and forth.

[0067] During operation, poor wire routing can cause vibration in the steel strand. If the position of the limit roller 382 remains fixed, the steel strand will break. Therefore, the limit roller 382 needs to be able to swing to a certain extent to keep the steel strand taut, thus preventing breakage due to vibration and ensuring the tension of the inner drum 10. Specifically, single bolts 39 are movably inserted through the protrusions on both sides of the limit seat 381. The tail end of the single bolt 39 is threaded to the frame 1 via the limit seat 381. After passing through the frame 1, the single bolt 39 is connected to a nut, which further ensures 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. A single compression spring 40 is sleeved on the single bolt 39, located between the boss of the limiting seat 381 and the head end of the single bolt 39. Thus, the limiting seat 381 can elastically slide on the single bolt 39, causing the limiting roller 382 to elastically slide away from or towards the drum seat 7, thereby changing the position of the limiting roller 382. The adjustment of the position of the limiting roller 382 can balance the winding force of the steel strand, ensure the optimal tension of the steel strand, and avoid damage to the wire.

[0068] When installing the corner guide wheel 18, a wheel mounting plate 41 is set on the outer wall of the brake cylinder 11, and the corner guide wheel 18 is rotatably set on the wheel mounting plate 41. The diameter of the corner guide wheel 18 is larger than the axial length of the brake cylinder 11. During the process of the steel strand passing through the corner guide wheel 18, in order to prevent the steel strand from detaching from the wheel, an anti-detachment plate 42 is fixedly connected to the wheel mounting plate 41. The anti-detachment plate 42 is located between the wheel mounting plate 41 and the corner guide wheel 18. The anti-detachment plate 42 is an integral structure composed of two strip plates connected in a V shape. The center of the top of the V-shape of the anti-detachment plate 42 is on the same axis as the center of the corner guide wheel 18. The included angle of the V-shape of the anti-detachment plate 42 is 120°-160°. The two strip plates of the anti-detachment plate 42 extend radially along the corner guide wheel 18, and the ends of the two strip plates of the anti-detachment plate 42 protrude from the edge of the corner guide wheel 18. The ends of the two strip plates of the anti-detachment plate 42 are rotatably provided with anti-detachment wheels 43 that are tangent to the corner guide wheel 18. The two anti-detachment wheels 43 correspond to the two ends of the brake cylinder 11 in the axial direction. The anti-detachment wheel 43 is thicker than the corner guide wheel 18. The anti-detachment wheel 43, together with the corner guide wheel 18, can restrict the passing steel strand and prevent the steel strand from detaching from the corner guide wheel 18.

[0069] Meanwhile, during the process of the steel strand winding out of the corner guide wheel 18 and 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 winding of the steel strand on the outer drum 12, a limiting rod 44 of the plate structure is provided on one of the two strip plates near the outer drum 12. The limiting rod 44 extends longitudinally towards the outer drum 12 and points to the end of the outer drum 12 near the brake cylinder 11. A limiting roller 45 is provided at the longitudinally extending end of the limiting rod 44. After the steel strand winds out of the corner guide wheel 18, it contacts the side wall of the limiting roller 45 near the corner guide wheel 18, and then is introduced from one end of the outer drum 12 and wound on the outer drum 12, preventing the steel strand from shifting its introduction position on the outer drum 12.

[0070] Similarly, to ensure stable wire tension of the outer drum 12, the limiting rod 44 is designed as a hinged split structure, comprising an upper limiting rod 441 and a lower limiting rod 442 hinged together. The upper limiting rod 441 is fitted with a limiting roller 45, and the lower limiting rod 442 is fixedly connected to the end of the anti-detachment plate 42. Upper abutment plates 47 are provided on both sides of the upper limiting rod 441, and lower abutment plates 48 are provided on both sides of the lower limiting rod 442. A retaining spring 49 is arranged between the corresponding lower abutment plates 48 and upper abutment plates 47. Cylindrical positioning blocks 46 are provided on both the lower abutment plates 48 and upper abutment plates 47 at both ends of the retaining spring 49, and the end of the retaining spring 49 is sleeved and fixed on the positioning blocks 46. When the retaining spring 49 is in a balanced state, the upper limiting rod 441 and lower limiting rod 442 maintain a straight-line arrangement. When the steel strand passes through the limiting roller 45, the limiting roller 45 can be made to swing according to the state of the steel strand, so as to balance the winding force of the steel strand, ensure the optimal tension of the steel strand and avoid damage to the wire.
