[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figure 1 and Figure 2 As shown, the present invention provides a cable winding device for underground coal mines, including a winding roller 10 for winding cables, a moving track 20 is arranged on one side of the winding roller 10, a straightening mechanism 30 is arranged on the moving track 20 and is located on one side of the winding roller 10, the straightening mechanism 30 makes a linear motion along the axial direction of the winding roller 10, guides the cable to be wound around the winding roller 10 in sequence, the straightening mechanism 30 rotates radially around the winding roller 10 on the outer wall of the cable to form an anti-twisting structure, a clamping mechanism 40 is arranged at the rotation center of the straightening mechanism 30, and the cable is wound by the winding roller 10 after passing through the clamping mechanism 40 to form a guided winding structure;

[0044] A tensioning mechanism 50 is provided on one side of the clamping mechanism 40 , and a control mechanism 60 is provided on the clamping mechanism 40 . The cable enters the clamping mechanism 40 through the tensioning mechanism 50 , and the tensioning mechanism 50 rotates to adjust the contact position with the cable to form a tension adjusting structure.

[0045] The present invention uses self-rotation to adjust the angle of cable transportation, further adjusts the cable tension, and cooperates with the guide tube to guide the cable to be transported to the winding roller, which is beneficial to the safe winding of the cable. The cable transportation is guided by the clamping mechanism, which is beneficial to control the cable transportation position, limit the twisting of the cable to help it straighten it, and move along the axial direction of the winding roller to cooperate with the winding, so as to achieve the purpose of orderly and neat winding, reduce manual intervention, improve winding efficiency, and reduce the occurrence of cable damage.

[0046] When the cable is rolled up by the winding roller 10, the straightening mechanism 30 is driven by the moving track 20 to follow the winding position of the cable on the winding roller 10 to move, which is conducive to controlling the cable to be at a suitable angle when it is sent to one side of the winding roller 10, and it is not easy to be twisted or skewed;

[0047] The clamping mechanism 40 controls the range of cable delivery and provides a reaction force to the cable when it is twisted to achieve the purpose of straightening, which helps to reduce the situation where the cable is twisted and affects the order of winding, thereby reducing the problem of possible wear of the twisted cable;

[0048] In conjunction with the tensioning adjustment mechanism 50 at the cable feeding end, the tension of the cable is adjusted as needed during the cable transportation process, so as to cooperate with the straightening mechanism 30 to achieve the purpose of orderly winding the cable. By controlling the tension of the cable during winding, the distortion and crookedness of the cable can be reduced, and at the same time, the loose winding of the cable can be avoided as much as possible, resulting in unevenness, which is conducive to improving the efficiency and quality of cable winding.

[0049] like Figure 2 , Figure 3 and Figure 4 As shown, the straightening mechanism 30 includes a support rod 31 and a fixed cylinder 32, the support rod 31 is connected to the motion track 20, and the support rod 31 moves linearly along the axial direction of the winding roller 10;

[0050] A movable cylinder 33 is arranged inside the fixed cylinder 32. The movable cylinder 33 radially rotates around the winding roller 10 to relieve the cable twisting and form a straightening structure.

[0051] The fixed cylinder 32 and the moving track 20 are connected by the support rod 31, and the straightening mechanism 30 is controlled by the moving track 20 to perform linear motion, so that it can move along with the winding position of the cable on the winding roller 10, which is beneficial to maintaining the angle of the cable when winding on one side of the winding roller 10, thereby achieving the purpose of neat winding.

[0052] The movable cylinder 33 rotates freely in the fixed cylinder 32, and drives the movable cylinder 33 to rotate when the cable is twisted. At the same time, the movable cylinder 33 applies a reverse force to the cable, which helps to straighten the cable and prevent it from twisting and affecting neat winding.

[0053] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the tension adjustment mechanism 50 includes a frame 51, a pulley block 52 and a rotating motor 53. After the pulley block 52 rotates around the connection between it and the frame 51, the bending degree of the cable is adjusted to form a tension adjustment structure;

[0054] The pulley block 52 includes a driving pulley 521 and a driven pulley 522. A driving shaft 523 is provided on the driving pulley 521, and a driven shaft 524 is provided on the driven pulley 522. The output shaft of the rotary motor 53 is connected to the driving shaft 523 through a coupling, and a connecting rod 525 connected to the driven shaft 524 is provided on the outer wall of the driving shaft 523. The driving shaft 523 is connected to the frame 51 through a bearing, and a slide groove matching the driven shaft 524 is provided on the frame 51.

[0055] The cable winds around the outer wall of the driven pulley 522 to the outer wall of the driving pulley 521 to form an S-shaped winding structure.

[0056] A tension sensor is provided on the active pulley 521, which can monitor the tension during the cable winding process, and further feed back to the tension adjustment mechanism 50, and drive the pulley group 52 to rotate by the rotating motor 53, so that the driven pulley 522 rotates together around the center of the active pulley 521;

[0057] When the driven pulley 522 rotates upward, the curvature of the cable between the driving pulley 521 and the driven pulley 522 is continuously slowed down, thereby reducing the contact surface between the cable and the driving pulley 521 and the driven pulley 522, thereby achieving the purpose of reducing tension and facilitating the adjustment process of the cable;

[0058] When the driven pulley 522 rotates downward, the curvature of the cable between the active pulley 521 and the driven pulley 522 is continuously increased, thereby increasing the contact surface between the cable and the active pulley 521 and the driven pulley 522, thereby achieving the purpose of increasing the tension and preventing the cable from being too loose, resulting in uneven winding or even tangled chaos.

[0059] like Figure 2 and Figure 7 As shown, the control mechanism 60 drives the clamping mechanism 40 to move along the radial direction of the cable. The control mechanism 60 includes a double-headed motor 61, a second screw rod 62 and a second slide 63. The second screw rod 62 drives the clamping mechanism 40 to move axially along the winding roller 10 and clamp the cable inside.

[0060] Among them, the output shaft of the double-headed motor 61 is fixedly connected to the second screw rod 62 through a coupling, and one end of the second screw rod 62 is connected to the movable cylinder 33 through a bearing, the lower surface of the second slide 63 is connected to the clamping mechanism 40, and the second slide 63 is threadedly connected to the second screw rod 62.

[0061] The second screw rods 62 at both ends are driven to move by the double-headed motor 61, so that the second slide 63 drives the clamping mechanism 40 to move, thereby clamping and fixing the cable. This is applicable to cables of more specifications and facilitates adjustment of the clamping distance.

[0062] It is convenient to control the movable range of the cable in the movable cylinder 33, and to guide the cable to be sent to the winding roller 10 for winding.

[0063] like Figure 3 , Figure 4 and Figure 7 As shown, the clamping mechanism 40 includes a guide tube 41 and an anti-twist assembly 42. The guide tube 41 guides the cable to enter the winding roller 10. The anti-twist assembly 42 is arranged in the guide tube 41 and movably abuts against the cable to form an anti-twist structure.

[0064] The outer wall of the guide tube 41 is provided with an elastic support assembly 43 installed in the straightening mechanism 30 .

[0065] The cable is clamped by the anti-twist assembly 42, so that the twisting of the cable can be controlled and the cable can be guided to be straightened for easy and neat winding.

[0066] The guide tube 41 is fixed and supported by the elastic support assembly 43. The guide tube 41 limits the range of cable movement inside the movable cylinder 33, thereby reducing the large shaking amplitude of the cable during the winding process that affects the neatness of the winding.

[0067] like Figure 4 As shown, the movable cylinder 33 includes a rotary bearing 331 disposed in the fixed cylinder 32 , the rotary bearing 331 is used to support the rotation of the movable cylinder 33 , and a torsion spring 332 is disposed in the rotary bearing 331 , the torsion spring 332 provides torque for the reverse rotation of the movable cylinder 33 .

[0068] The movable cylinder 33 rotates in the fixed cylinder 32 through the rotating bearing 331. The torsion spring 332 connects the rotating bearing 331 and the fixed cylinder 32 to control the rotation angle of the rotating bearing 331, further control the rotation of the movable cylinder 33, and provide a reverse force for the movable cylinder 33 when it rotates.

[0069] The movable cylinder 33 and the cable are connected by the clamping mechanism 40. When the cable is twisted, the movable cylinder 33 is driven to rotate and a force in one direction is applied to the torsion spring 332. The rebound of the torsion spring 332 drives the movable cylinder 33 and the cable to rotate in the opposite direction, thereby reducing the twisting of the cable and helping to straighten the cable to achieve the purpose of neat winding.

[0070] like Figure 1 As shown, the winding roller 10 includes a winding shaft 11, a driving motor 12 and a limiting plate 13. The driving motor 12 drives the winding shaft 11 to rotate to drive the cable to be wound. The limiting plate 13 forms a limiting structure for the cable at both ends of the winding roller 10.

[0071] The driving motor 12 is connected to the winding roller 10 through the winding shaft 11, driving the winding roller 10 to rotate to reel in the cable. At the same time, the limit plate 13 protects the two ends of the winding roller 10 to limit the cable reeling range, which is conducive to keeping the cable neatly reeled on the winding roller 10.

[0072] like Figure 4 and Figure 7As shown, the anti-twist assembly 42 includes a clamping block 421 movably arranged in the guide tube 41, a groove matching the clamping block 421 is provided on one side of the guide tube 41, the clamping block 421 is connected to the second slide 63, protrusions 422 are provided on both sides of the clamping block 421, and a protrusion groove matching the protrusion 422 is provided on one side of the guide tube 41 close to the groove. After the clamping block 421 slides to one end of the guide tube 41, the protrusion 422 movably abuts against the guide tube 41, driving the guide tube 41 to stretch and movably abut against the cable, and a roller group 423 is provided in the clamping block 421, and the roller group 423 rotates around the connection between it and the clamping block 421 to guide the cable to enter the winding roller 10;

[0073] The elastic support assembly 43 supports the guide tube 41 at the center position inside the movable cylinder 33, and the cable passes through the guide tube 41 and is sent to the winding roller 10. The elastic support assembly 43 includes a support 431 fixed to the inner wall of the movable cylinder 33, and a telescopic rod 432 connected to the guide tube 41 is arranged at one end of the support 431, and a spring 433 is arranged at one end of the support 431 and is sleeved on the outer wall of the telescopic rod 432.

[0074] First, the guide tube 41 is used to limit the range of movement of the cable. When winding, the double-headed motor 61 and the second screw rod 62 drive the second slide 63 to move, further driving the clamping block 421 to move. When the clamping block 421 moves to the inside of the guide tube 41, the protrusion 422 abuts against the protrusion groove in the guide tube 41, so that the clamping block 421 further drives the guide tube 41 to move toward the cable, and the cable is clamped by the clamping blocks 421 and the guide tube 41 on both sides;

[0075] The connection between the guide tube 41 and the support 431 is stretched by the telescopic rod 432, and the spring 433 provides a rebound force therefor. When the clamp 421 is away from the inside of the guide tube 41, the guide tube 41 rebounds to the initial position through the spring, maintaining a certain range of movement of the cable.

[0076] At the same time, the roller group 423 in the clamping block 421 contacts the cable, and guides the transmission of the cable while clamping the cable. The roller group 423 is composed of multiple groups of rollers and roller shafts, and the multiple groups of rollers are movably connected to the inside of the clamping block 421 through the roller shafts, so that the rotation of the rollers during the cable transmission process is beneficial to further guide the transmission of the cable, so that the clamping block 421 can control the rotation of the cable without affecting the transmission of the cable. When the cable is twisted, it is fed back to the clamping block 421, and the anti-twist component 42 provides a reverse force to help straighten the cable, thereby facilitating neat winding.

[0077] like Figure 1 As shown, the winding roller 10 is provided with a control unit 70 connected to the tension adjustment mechanism 50 and the control mechanism 60 respectively. The control unit 70 is connected to the driving motor 12 to cooperate with the winding roller 10 to form a speed control structure.

[0078] The control unit 70 is connected to the tension sensor to form a tension adjustment structure, and the control unit 70 is connected to the screw motor 64 and cooperates with the clamping mechanism 40 to form a reciprocating motion structure.

[0079] The control unit 70 has a wireless control module, which is respectively connected to the tensioning sensor, the lead screw motor 64 and the winding roller 10, so as to synchronously transmit the signal to the tensioning sensor and the lead screw motor 64 while the winding roller 10 is winding, so as to coordinate the work.

[0080] like Figure 2 As shown, the motion track 20 includes a first screw motor 21, a first screw 22 and a first slide 23. The output shaft of the first screw motor 21 is connected to the first screw 22 through a coupling, and the first slide 23 is threadedly connected to the first screw 22. The top end of the first slide 23 is fixedly connected to the support rod 31.

[0081] The first screw motor 21 drives the first screw 22 to rotate, causing the first slide 23 to move, thereby driving the straightening mechanism 30 to move axially along the winding roller 10 through the support rod 31, so that the straightening mechanism 30 can move together with the cable winding position on the winding roller 10, thereby maintaining the angle of the cable on the winding roller 10, which is beneficial to reduce the twisting and tilting of the cable, thereby achieving the purpose of orderly winding in sequence.

[0082] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
