Description

Technical Field

[0001] This application relates to the technical field of coiling systems, and more particularly to a coiling device and a coiling system. Background Art

[0002] At present, when the finished cables in cable factories leave the factory, they are basically coiled with wooden cable reels. However, the overall size of the cable reels coiled with wooden cable reels is relatively large, resulting in many problems such as increased costs, inconvenient transportation and unloading, no space to accommodate on-site, and inconvenient on-site construction. Summary of the Utility Model

[0003] This application aims to at least solve the problems of increased costs, inconvenient transportation and unloading, no space to accommodate on-site, and inconvenient on-site construction caused by the relatively large overall size of the cable reels in the above-mentioned prior art or related technologies.

[0004] To achieve the above object, the first aspect embodiment of this application provides a coiling device, which includes: a main shaft, a core shaft, and a variable diameter driving mechanism. Among them, the core shaft is arranged on the main shaft to rotate under the drive of the main shaft. The core shaft is formed by enclosing multiple core shaft segments. The multiple core shaft segments are arranged around the main shaft and can move relative to the main shaft; the variable diameter driving mechanism is arranged on the main shaft and is used to drive the multiple core shaft segments to approach or move away from the main shaft to adjust the diameter of the core shaft.

[0005] According to the coiling device provided by the embodiment of this application, during use, the approximate diameter of the required core shaft can be estimated according to the basic parameters of different cables, and then the diameter of the core shaft can be adjusted according to the estimated diameter. In this way, without damaging the basic performance of the cable, the overall size of the cable after coiling can be avoided from being too large, thereby solving the problems of increased costs, inconvenient transportation and unloading, no space to accommodate on-site, and inconvenient on-site construction caused by the relatively large overall size of the cable after coiling.

[0006] In some embodiments, the variable diameter driving mechanism includes an adjusting plate. The adjusting plate is sleeved on the main shaft and can rotate around the main shaft. An arc-shaped groove is arranged on the adjusting plate, and the arc-shaped groove is an involute-shaped groove. A pin is arranged at the lower end of the core shaft segment, and the pin of each core shaft segment is correspondingly inserted into each arc-shaped groove. When the adjusting plate rotates, it can drive each core shaft segment to move in the arc-shaped groove, thereby changing the diameter of the core shaft.

[0007] In these embodiments, the arc-shaped groove is an involute-shaped groove. Different positions of the arc-shaped groove have different radii relative to the main shaft. As the adjusting plate rotates, the movement of the pin column in the arc-shaped groove can generate a movement component in the radial direction of the main shaft, causing the split mandrels to approach or move away from the main shaft relative to each other, thereby changing the overall diameter of the mandrel to adapt to different cable coiling requirements.

[0008] In some embodiments, the variable-diameter drive mechanism further includes a guiding support plate. The guiding support plate is fixedly installed on the main shaft. A guiding groove extending along the radial direction of the guiding support plate is provided on the guiding support plate. The pin column is also inserted into the guiding groove, such that the split mandrels move along the radial direction of the guiding support plate.

[0009] In these embodiments, the arc-shaped groove is an involute-shaped groove. Different positions of the arc-shaped groove have different radii relative to the main shaft. The guiding groove extends along the radial direction of the guiding support plate, and the pin column can move in both the arc-shaped groove and the guiding groove simultaneously. In this case, when the adjusting plate rotates, under the combined constraint of the arc-shaped groove and the guiding groove, the pin column can move in the radial direction to drive the split mandrels to move in the radial direction, avoiding the split mandrels from shifting or misaligning during the movement, and ensuring the stability and accuracy of the movement of the split mandrels. As the split mandrels move, the overall diameter of the mandrel will change to adapt to different cable coiling requirements.

[0010] In some embodiments, a supporting tray is fixedly connected to the lower end of the split mandrel. The pin column extends downward from the lower surface of the supporting tray. The guiding support plate is arranged below the supporting tray, and the adjusting plate is located below the guiding support plate. The variable-diameter drive mechanism further includes a plurality of supporting track assemblies extending along the radial direction of the guiding support plate. Each supporting track assembly includes a slide rail provided on the guiding support plate and a sliding groove provided on the lower surface of the supporting tray. The sliding groove cooperates with the slide rail to respectively support each split mandrel.

[0011] In these embodiments, the supporting track assembly including the sliding groove and the slide rail can provide sliding support in the radial direction for each supporting tray, such that the split mandrels can move along a predetermined path and at a predetermined speed, avoiding deviating from the track due to external forces or other factors, thereby ensuring the stability and reliability of the split mandrels during the movement. In addition, the arrangement of the supporting track assembly can increase the smoothness and flexibility of the movement of the split mandrels. Moreover, the arrangement of the supporting track assembly can slidably carry the upper split mandrels and the supporting trays above, reduce the friction between the supporting trays and the guiding support plate, avoid jamming during the movement, improve the movement efficiency, reduce energy consumption, and extend the service life of the device.

[0012] In some embodiments, the variable-diameter drive mechanism further includes a drive motor, which is disposed on the main shaft, below the adjustment plate, and is connected to the adjustment plate for driving the adjustment plate to rotate around the main shaft.

[0013] In these embodiments, by driving the adjustment plate to rotate through the drive motor to automatically adjust the diameter of the mandrel, it can not only improve work efficiency and reduce operation difficulty, but also reduce labor intensity and facilitate automatic setting.

[0014] In some embodiments, the coiling device further includes a coil tray, which can be disposed on the support tray for supporting the wound coil.

[0015] In these embodiments, by providing the coil tray, the support area during cable coiling can be increased, preventing the cable from slipping or shifting during coiling, and ensuring that the cable can be wound neatly and tightly on the coil. Additionally, the coil tray can be provided to facilitate the fixation of the cable after coiling is completed, avoiding the cable from becoming scattered.

[0016] In some embodiments, the coiling device further includes a support frame and a lifting drive mechanism. The support frame includes a top plate with an opening. The mandrel is disposed below the top plate, and the lifting drive mechanism can drive the mandrel to move upward through the opening or move downward and retract below the opening.

[0017] In these embodiments, by providing the lifting drive mechanism, it is convenient to adjust the position of the mandrel according to actual needs. For example, before coiling, the lifting drive mechanism can move the mandrel upward so that it passes through a predetermined opening and is positioned on one side of the wire arranging unit mentioned below. In this way, it can ensure that the cable smoothly transitions from the wire arranging unit to the mandrel during coiling, reducing cable twisting and knotting, and further improving the quality of the coiled cable. After coiling is completed, the lifting drive mechanism can move the mandrel downward so that it retracts below the opening. With this setting, the cable can be easily withdrawn from the mandrel, providing convenience for the next coiling operation. In addition, when the mandrel is in the retracted state, it can also reduce the floor area and facilitate storage. Moreover, the setting of the lifting drive mechanism can not only improve work efficiency and reduce operation difficulty, but also reduce labor intensity and facilitate automatic setting.

[0018] In some embodiments, a chuck is provided on the coil tray. The chuck can fix the end of the cable. The coil tray can cover the opening and, after the mandrel moves upward and the support tray passes through the opening, be seated on the support tray.

[0019] In these embodiments, the chuck can fix the end of the cable. The starting end of the cable can be kept stable, not easy to slide or shift, so as to ensure that the cable can be wound neatly and tightly on the cable reel. When it is necessary to coil the cable, first, the mandrel is moved upward by the lifting drive mechanism until the support pallet passes through the opening of the top plate. During this process, the cable reel pallet originally covers the opening. As the mandrel rises, the cable reel pallet is pushed away or moved aside and seated on the support pallet. In this way, the cable reel pallet can rotate together with the support pallet. When the end of the cable is fixed, the rotation of the cable reel pallet and the support pallet together can ensure that the cable is not excessively bent. In addition, the rotation of the cable reel pallet and the support pallet together can reduce the friction during the coiling process, ensuring the smoothness of coiling and the service life of the device. After the coiling is completed, the lifting drive mechanism is started again to lower the mandrel below the opening. Subsequently, the mandrel can be separated from the cable coil and the cable reel pallet, and the cable coil and the cable reel pallet can be removed and fixed for subsequent use.

[0020] In some embodiments, the support frame includes a base located below the top plate. The lifting drive mechanism includes: a connecting bottom plate, a plurality of adjusting lead screws, and a drive unit. Among them, the connecting bottom plate is fixedly connected to the lower end of the main shaft; the adjusting lead screws are rotatably arranged on the base. The connecting bottom plate is sleeved on the plurality of adjusting lead screws and is threadedly connected to each adjusting lead screw. The drive unit is connected to the adjusting lead screw and can drive the adjusting lead screw to rotate to drive the connecting bottom plate to move in the height direction.

[0021] In these embodiments, the movement of the connecting bottom plate in the height direction can be realized through the lead screw-nut structure. The connecting bottom plate is fixedly connected to the lower end of the main shaft. When the connecting bottom plate moves, the main shaft and the mandrel will also move up and down accordingly, so that the mandrel can extend out or retract from the opening. The lifting drive mechanism adopting a plurality of adjusting lead screws and a drive unit can jointly bear the weight of the upper components (the main shaft and the mandrel) and evenly transmit the power, making the mandrel more stable and reliable during the up and down movement.

[0022] In some embodiments, the coiling device is used to coil the cable. The coiling device further includes a wire arranging unit and a servo motor. The wire arranging unit is arranged on the top plate. The wire arranging unit has a wire outlet roller; the servo motor is communicatively connected to the wire outlet roller and is used to measure the length of the cable output through the wire outlet roller.

[0023] In these embodiments, during the coiling process, the cable can drive the wire outlet roller to move under the traction force of the mandrel. Since the servo motor is communicatively connected to the wire outlet roller, the servo motor can monitor the passive rotation of the wire outlet roller in real time to calculate and output the length of the cable, so as to obtain the actual coiling length of the cable, which is convenient for marking the length of the cable coil obtained by coiling.

[0024] In some embodiments, through holes are provided on the coil tray, the bending radius of the mandrel in the circumferential direction is greater than the minimum bending radius of the cable, and the part of the mandrel extending out of the through hole is substantially flush with the wire outlet roller.

[0025] In these embodiments, the bending radius of the mandrel in the circumferential direction is greater than the minimum bending radius of the cable, which can ensure that the cable will not be excessively bent during the bending process, thus affecting its service performance and ensuring the quality of the coiled cable. Through holes are also provided on the coil tray, and the part of the mandrel extending out of the through hole is substantially flush with the wire outlet roller. In this way, the cable can smoothly transition between the two during the coiling process, further ensuring the quality of the coiled cable.

[0026] According to a second aspect of the present application, a coiling system is provided, wherein the coiling system includes the coiling device provided in each of the above embodiments and an unwinding device connected to the coiling device. Description of the Drawings

[0053] The following will be combined with Figures 1 to 7 to introduce the coiling device and coiling system provided by the embodiments of this application.

[0054] An embodiment of the present application provides a coiling device, which is at least used for coiling a cable 200. As shown in Figures 1 to 7 , the coiling device includes a main shaft 10, a mandrel 30, and a variable-diameter driving mechanism 20. The mandrel 30 is at least used for coiling the cable, is arranged on the main shaft 10, and can rotate driven by the main shaft 10. The mandrel 30 is formed by enclosing a plurality of mandrel segments 31. The plurality of mandrel segments 31 are arranged around the main shaft 10 on the outer periphery of the main shaft 10 and can move relative to the main shaft 10. The variable-diameter driving mechanism 20 is arranged on the main shaft 10 and is used to drive the plurality of mandrel segments 31 to approach or move away from the main shaft 10 so as to adjust the diameter of the mandrel 30.

[0055] In the embodiment of the present application, the main shaft 10 can rotate, so as to drive the mandrel 30 connected thereto to rotate, and thus wind the cable around the mandrel 30. The mandrel 30 is composed of a plurality of mandrel segments 31. As an example, the mandrel segment 31 can be columnar or arc-shaped plate-like, so that a plurality of columnar or arc-shaped plate-like mandrel segments 31 can enclose to form a generally cylindrical mandrel 30. By enclosing to form the mandrel 30 with different sizes, thus, the size of the mandrel 30 can be flexibly adjusted to be suitable for coiling various linear materials. As an example, the linear material can be a cable. Specifically, the cable can be an electric cable or other types of wires (for example, an optical fiber cable). When the coiling device is used to coil the cable, the overall diameter of the required mandrel 30 can be estimated according to the minimum bending radius of the cable, and then each mandrel segment 31 approaches or moves away from the main shaft 10 to change the diameter of the mandrel 30 to ensure that the cable will not be damaged due to excessive bending during the coiling process.

[0056] For the coiling device provided by the embodiment of the present application, during use, the general diameter of the required mandrel can be estimated according to the basic parameters of different cables (such as the minimum bending radius, length, wire diameter, inner diameter, and outer diameter, etc.). When it is necessary to adjust the diameter of the mandrel 30, the variable-diameter driving mechanism 20 can drive the plurality of mandrel segments 31 to approach or move away from the main shaft 10. As the mandrel segments 31 move, the diameter of the mandrel 30 also changes accordingly. When the diameter of the mandrel 30 is adjusted to the pre-estimated diameter, the variable-diameter driving mechanism 20 stops working. Then, the main shaft 10 rotates and drives the mandrel 30 to rotate, so that the cable to be coiled is coiled around the mandrel 30, thereby completing the coiling work of the cable.

[0057] According to the coiling device provided by the embodiments of the present application, the diameter of the mandrel 30 is adjustable, which can bring great convenience to the coiling process of the cable. For example, during use, the approximate diameter of the mandrel 30 required can be estimated according to the basic parameters of different cables, and then the mandrel 30 can be adjusted according to the estimated diameter. In this way, without damaging the basic performance of the cable, the overall size of the coiled cable can be prevented from being too large, thereby solving the problems of increased cost, inconvenient transportation and unloading, lack of space for accommodation at the site, and inconvenient on-site construction caused by the too large overall size of the coiled cable. In addition, the mandrel 30 with an adjustable diameter not only improves the applicability of the coiling device, enabling it to handle cables of various different materials and specifications, but also improves the safety and efficiency of the coiling process. Moreover, by controlling the diameter of the mandrel, it is possible to ensure that the cable maintains an appropriate tension during the coiling process, avoiding damage or slack of the cable, and improving the coiling quality.

[0058] According to the present application, the variable-diameter drive mechanism 20 drives a plurality of mandrel segments 31 so that they can move radially relative to the main shaft 10. In this way, the diameter of the mandrel 30 can be adjusted. Specifically, when the mandrel segments 31 move outward, the diameter of the mandrel 30 increases, and when the mandrel segments 31 move inward, the diameter of the mandrel 30 decreases.

[0059] In some embodiments, the variable-diameter drive mechanism 20 includes an adjustment plate 23. The adjustment plate 23 is sleeved on the main shaft 10 and can rotate around the main shaft 10. A plurality of arc-shaped grooves 231 are provided on the adjustment plate 23. The arc-shaped grooves 231 are involute-shaped grooves. A pin 33 is provided at the lower end of each mandrel segment 31. The pin 33 of each mandrel segment 31 is correspondingly inserted into the corresponding arc-shaped groove 231. When the adjustment plate 23 rotates, each mandrel segment 31 can be driven to move in the arc-shaped groove 231 through the cooperation of the pin 33 and the arc-shaped groove 231, thereby changing the diameter of the mandrel 30.

[0060] In the embodiments of the present application, the arc-shaped grooves 231 are involute-shaped grooves. Different positions of the arc-shaped grooves 231 have different radii relative to the main shaft 10. As the adjustment plate 23 rotates, the movement of the pin 33 in the arc-shaped groove 231 can generate a radial movement component along the main shaft 10, causing the respective mandrel segments 31 to approach or move away from the main shaft 10, thereby changing the overall diameter of the mandrel 30 to meet the coiling requirements of cables of different specifications or materials.

[0061] In some embodiments, such as Figures 1 to 4As shown, the variable-diameter drive mechanism 20 further includes a guiding support plate 21. The guiding support plate 21 is fixedly installed on the main shaft 10 and serves as a guiding and supporting structure for the movement of the split mandrel 31. Specifically, the guiding support plate 21 is generally circular and is coaxially arranged with the main shaft 10. A guiding groove 211 extending along the radial direction of the guiding support plate 21 is provided on the guiding support plate 21, and the pin 33 is also inserted into the guiding groove 211, so that the split mandrel 31 moves along the radial direction of the guiding support plate 21.

[0062] In these embodiments, the arc-shaped groove 231 is an involute-shaped groove. Different positions of the arc-shaped groove 231 have different radii relative to the main shaft 10. The guiding groove 211 extends along the radial direction of the guiding support plate 21, and the pin 33 can move in both the arc-shaped groove 231 and the guiding groove 211 simultaneously. In this case, when the adjusting plate 23 rotates, under the combined restraint of the arc-shaped groove 231 and the guiding groove 211, the pin 33 can move in the radial direction to drive the split mandrel 31 to move in the radial direction, preventing the split mandrel 31 from shifting or misaligning during the movement and ensuring the stability and accuracy of the movement of the split mandrel 31. As the split mandrel 31 moves, the overall diameter of the mandrel 30 will change to adapt to different cable coiling requirements.

[0063] In some embodiments, a supporting tray 32 is fixedly connected to the lower end of the split mandrel 31. As an example, the supporting tray 32 extends radially outward from the lower end of the split mandrel 31, the pin 33 extends downward from the lower surface of the supporting tray 32, the guiding support plate 21 is arranged below the supporting tray 32, the adjusting plate 23 is located below the guiding support plate 21, and the pin 33 is inserted into the arc-shaped groove 231 after passing through the guiding groove 211. The variable-diameter drive mechanism 20 further includes a plurality of supporting track assemblies 22 extending along the radial direction of the guiding support plate 21. The supporting track assemblies 22 include slide rails 221 arranged on the guiding support plate 21 and sliding grooves 222 arranged on the lower surface of the supporting tray 32. The sliding grooves 222 cooperate with the slide rails 221 to support each split mandrel 31 respectively. Obviously, the positions of the slide rails 221 and the sliding grooves 222 can be interchanged.

[0064] In these embodiments, the supporting track assemblies 22 including the sliding grooves 222 and the slide rails 221 can provide sliding support in the radial direction for each supporting tray 32, enabling the split mandrel 31 to move along a predetermined path and at a predetermined speed, preventing deviation from the track due to external forces or other factors, and the arrangement of the supporting track assemblies 22 can slidably carry the upper split mandrel 31, thereby ensuring the stability and reliability of the split mandrel 31 during the movement.

[0065] In some embodiments, the variable-diameter drive mechanism 20 further includes a drive motor 24. The drive motor 24 is disposed on the main shaft 10 or other fixed support structures, below the adjustment plate 23, and is connected to the adjustment plate 23 for driving the adjustment plate 23 to rotate around the main shaft 10.

[0066] In these embodiments, by driving the adjustment plate 23 to rotate through the drive motor 24 to automatically adjust the diameter of the mandrel 30, not only can the working efficiency be improved and the operation difficulty be reduced, but also the labor intensity can be reduced and the automation setting can be facilitated.

[0067] In some embodiments, the coiling device further includes a coil tray 70. The coil tray 70 is disposed on the support tray 32 for supporting the wound coil.

[0068] In these embodiments, by providing the coil tray 70, the cable coil can be better supported and fixed. Specifically, the coil tray 70 can increase the support area during cable coiling, prevent the cable from sliding or shifting during the coiling process, and ensure that the cable can be wound neatly and tightly on the coil. In addition, the coil tray 70 can facilitate the fixing after the cable coiling is completed and prevent the cable from being scattered. During use, the coil tray 70 is sleeved on the outer periphery of the mandrel 30 and disposed on the support tray 32, and then one end of the cable is wound around the mandrel 30 and fixed on the coil tray 70. When the mandrel 30 rotates, the cable can be wound around the mandrel 30. After the cable coiling is completed, the mandrel 30 can be withdrawn from the cable coil, and then the coil tray 70 together with the cable coil can be removed and stored after being fixed.

[0069] According to the present application, the coil tray 70 is provided with a cable tying groove. When the coiling device completes the coiling operation, a cable tie can be used to tie and fix the cable coil through the cable tying groove on the coil tray 70. In this way, the fixing of the cable coil can be ensured, the cable can be prevented from being scattered during the movement process, and the subsequent use, taking and placing are facilitated.

[0070] In some embodiments, the bending radius of the mandrel 30 in the circumferential direction is greater than the minimum bending radius of the cable, which can ensure that the cable will not be excessively bent during the bending process and affect its use performance, and can guarantee the quality of the coiled cable. The coil tray 70 is further provided with a through hole 71. The part of the mandrel 30 extending out of the through hole 71 is flush with the wire outlet roller 91. In this way, the cable smoothly transitions between the two, and can further guarantee the quality of the coiled cable. It should be noted that since there is no need for excessive control accuracy between the part of the mandrel 30 extending out of the through hole 71 and the wire outlet roller 91, the part of the mandrel 30 extending out of the through hole 71 and the wire outlet roller 91 can be substantially flush.

[0071] Cables are usually relatively heavy. To ensure that in some embodiments, the coiling device further includes a support frame and a lifting drive mechanism 50. The support frame includes a top plate 60, and the top plate 60 has an opening 61. The mandrel 30 is disposed below the top plate 60. The lifting drive mechanism 50 can drive the mandrel 30 to move upward through the opening 61 or move downward and retract below the opening 61.

[0072] In these embodiments, by providing the lifting drive mechanism 50, it is possible to facilitate the adjustment of the position of the mandrel 30 according to actual needs. For example, before coiling, the lifting drive mechanism 50 can move the mandrel upward so that it passes through a predetermined opening 61 and is positioned on one side of the wire arranging unit 90 mentioned below. In this way, it can ensure that the cable smoothly transitions from the wire arranging unit to the mandrel during the coiling process, reducing cable twisting and knotting, and further improving the quality of the coiled cable. The diameter of the opening 61 is larger than the outer diameter of the support tray 32, so that the support tray 32 can pass through the opening 61. After the coiling is completed, the lifting drive mechanism 50 can move the mandrel downward again so that it retracts below the opening 61. Such a setting facilitates the extraction of the mandrel 30 from the cable coil and the removal of the cable coil. In addition, when the mandrel is in the retracted state, it can also reduce the floor area and facilitate storage. In addition, the setting of the lifting drive mechanism 50 can not only improve work efficiency, but also reduce the operation difficulty and labor intensity. The staff does not need to manually move the mandrel, and only needs to control the lifting drive mechanism to complete the position adjustment of the mandrel. In this way, the possibility of human operation errors can be reduced, making the entire coiling process more stable and reliable. In addition, the introduction of the lifting drive mechanism 50 also makes automation possible. According to the present application, in combination with the control system, the lifting drive mechanism can automatically adjust the position of the mandrel 30 according to a preset program to realize the automatic operation of cable coiling.

[0073] According to the present application, as Figure 1 and Figure 2 shown, the wire spool tray 70 is provided with a chuck 72, and the chuck 72 can fix the end of the cable 200. In some embodiments, the wire spool tray 70 can cover the opening 61 and be supported by the top plate 60. After the mandrel 30 moves upward and the support tray 32 passes through the opening, the support tray 32 can push the wire spool tray 70 upward, so that the wire spool tray 70 is seated on the support tray 32.

[0074] In these embodiments, the chuck 72 can fix the end of the cable. The starting end of the cable can be kept stable, not easy to slide or shift, so as to ensure that the cable can be wound around the cable reel neatly and tightly. When the cable needs to be coiled, first, the mandrel 30 is moved upward by the lifting drive mechanism 50 until the support plate 32 passes through the opening 61 of the top plate 60. During this process, the cable reel support plate 70 originally covers the opening 61. As the mandrel 30 rises, the cable reel support plate 70 is pushed and seated on the support plate 32. In this way, the cable reel support plate 70 can rotate together with the support plate 32. When the end of the cable is fixed, the rotation of the cable reel support plate 70 and the support plate 32 together can ensure that the cable is not overly bent. In addition, the rotation of the cable reel support plate 70 and the support plate 32 together can reduce the friction during the coiling process, ensuring the smoothness of coiling and the service life of the device. After the coiling is completed, the lifting drive mechanism 50 is started again to lower the mandrel 30 below the opening 61. Subsequently, the mandrel 30 can be separated from the cable reel and the cable reel support plate 70, and the cable reel and the cable reel support plate 70 can be removed and fixed for subsequent use. Before moving the mandrel 30 downward, the diameter of the mandrel 30 can be reduced by the diameter-changing drive mechanism 20 to facilitate separation from the cable reel.

[0075] According to the present application, multiple hydraulic cylinders, pneumatic cylinders or oil cylinders can be used as the lifting drive mechanism 50 to drive the mandrel 30 to move up and down in the height direction. To further ensure the stability of the up and down movement, in some embodiments, as Figure 1 , Figure 5 and Figure 6 shown, the support frame includes a base 40, the base 40 is located below the top plate 60, the lifting drive mechanism 50 includes a connecting bottom plate 51, a plurality of adjusting lead screws 52 and a driving unit 53. The connecting bottom plate 51 is fixedly connected to the lower end of the main shaft 10. The adjusting lead screws 52 are rotatably arranged on the base 40. The connecting bottom plate 51 is sleeved on the plurality of adjusting lead screws 52 and is threadedly connected to each adjusting lead screw 52. The driving unit 53 is connected to the adjusting lead screw 52 and can drive the adjusting lead screw 52 to rotate to drive the connecting bottom plate 51 to move in the height direction.

[0076] As an example, the adjusting lead screw 52 consists of at least three, and at least three adjusting lead screws 52 rotate synchronously (linkage). The driving unit 53 can be a power device such as a motor or a hydraulic motor, and transmits power to multiple adjusting lead screws 52 through a transmission mechanism (such as a chain, a belt, etc.) to make them rotate synchronously. When the driving unit 53 works, the adjusting lead screws 52 will rotate synchronously, thereby driving the connecting base plate 51 to move smoothly in the height direction. Specifically, when the adjusting lead screw 52 rotates forward, the connecting base plate 51 will move upward along the lead screw, thereby driving the main shaft 10 and the core shaft 30 to move upward until the supporting tray 32 passes through the opening 61 of the top plate 60. When the adjusting lead screw 52 rotates reversely, the connecting base plate 51 will move downward along the lead screw, thereby driving the main shaft 10 and the core shaft 30 to move downward until they retract below the opening 61.

[0077] In these embodiments, the connecting base plate 51 can be moved in the height direction through a lead screw-nut structure. The connecting base plate 51 is fixedly connected to the lower end of the main shaft 10. When the connecting base plate 51 moves, the main shaft 10 and the core shaft 30 will also move up and down accordingly, so that the core shaft 30 can extend out or retract from the opening 61. The lifting drive mechanism 50 with multiple adjusting lead screws 52 and the driving unit 53 can jointly bear the weight of the upper components (the main shaft 10 and the core shaft 30) and evenly transmit power, making the core shaft 30 more stable and reliable during the up and down movement.

[0078] In the embodiment of the present application, the base 40 is the bottom structure of the support frame, located below the top plate 60, providing stable support for the entire device. The top plate 60 is the top structure of the support frame, having an opening 61, at least for setting the wire arranging unit 90 mentioned later. An accommodating space 80 is formed between the base 40 and the top plate 60, and the core shaft 30 is located in the accommodating space 80 when it retracts below the opening 61.

[0079] In some embodiments, the coiling device is used for coiling cables. The coiling device further includes a wire arranging unit 90 and a servo motor 100. The wire arranging unit 90 is arranged on the top plate 60. The wire arranging unit 90 has a wire outlet roller 91, and the servo motor 100 is communicatively connected to the wire outlet roller 91 for measuring the length of the cable output through the wire outlet roller 91.

[0080] In the embodiment of the present application, the wire outlet roller 91 is used to pull out the cable from a pay-off device (such as a wooden cable reel) and guide its general direction. The wire outlet roller 91 can be one or more, and the specific number is set according to the design requirements and the cable type.

[0081] In these embodiments, the servo motor 100 is communicatively connected to the wire outlet roller 91. During the coiling process, the wire can drive the movement of the wire outlet roller 91 under the traction force of the mandrel 30. Since the servo motor 100 is communicatively connected to the wire outlet roller 91, the servo motor 100 monitors the passive rotation of the wire outlet roller 91 in real time through an internal encoder or other sensors to calculate and output the length of the wire, so that the actual coiling length of the wire can be obtained, facilitating the length marking of the coiled wire reel.

[0082] According to the present application, the coiling device further includes a main drive mechanism. Among them, the main drive mechanism includes a main control motor 110 and a speed reducer 120. The speed reducer 120 is installed on the main shaft 10, and the main control motor 110 drives the speed reducer 120 to rotate to drive the main shaft 10 to rotate.

[0083] According to the present application, the coiling device further includes a safety warning mechanism 130, which is used to monitor whether there is any personnel interference in the working area of the coiling device during the normal coiling operation of the coiling device. As an example, the safety warning mechanism 130 is a safety grating, which can provide safety protection for personnel during the operation of the coiling device.

[0084] According to the present application, the coiling device further includes a control system and a display interface connected to the control system. The control system is communicatively connected to the drive motor 24, the main control motor 110, and the drive unit 53 respectively to correspondingly control the movement of each part. The display interface is used to display the parameter setting options of the corresponding components.

[0085] According to the second aspect of the present application, a coiling system is provided. Among them, the coiling system includes the coiling device provided in each of the above embodiments and an unwinding device connected to the coiling device.

[0086] In some embodiments, the unwinding device is used to provide the wire to be coiled. In the unwinding device, the wire is coiled on the unwinding roller of the unwinding device in a size larger than the size after coiling. For example, the wire is wound on a wooden wire reel. Through the coiling device of the present application, the size of the wire after coiling can be reduced, eliminating the cost of the wooden wire reel, facilitating transportation, unloading, storage, and on-site operation, and being more suitable for the actual requirements of wind turbine generators.

[0087] Although the embodiments of the present application have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. However, it should be understood that in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present application defined by the claims.
