Description

Technical Field

[0001] The invention relates to the field of rope making machines, and in particular to a tension control device and a tension control method for a C-type D-type rope making machine. Background Art

[0002] C steel rope is a core containing multiple strands of steel wire (i.e. steel wire rope) in each strand. The synthetic rope also contains a core containing multiple strands of steel wire (i.e. steel wire rope), and is covered with a plastic braid of PP or PE material. This kind of rope is relatively hard, not easy to bend, and has high elasticity. Plastic and steel wire are mixed together. The rope needs to be twisted on a C steel rope D-type rope making machine. This equipment belongs to a type of D-type rope making machine. Compared with ordinary D-type rope making machines of the same specifications, the power of the rope twisting motor, traction motor and rope collection motor are all large; the tension of the rope is very large, and it is necessary to add a damping tension control device for each strand. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a tension control device and a tension control method for a C-type D-type steel rope making machine.

[0004] The camming device is a device for activating a tensioning mechanism, wherein the camming mechanism is adapted to move the camming mechanism upwards and downwards, and the camming mechanism is adapted to move the camming mechanism upwards and downwards, and the camming mechanism is adapted to move the camming mechanism upwards and downwards, and the camming mechanism is adapted to move the camming mechanism upwards and downwards, and the camming mechanism is adapted to move the camming mechanism upwards and downwards,

[0005] In this solution, the strands passing through the rope closing shaft are guided from the inside of the fixed tensioning wheel, then bypass the outside of the movable tensioning wheel, and then enter the die mouth. The adjustable tensioning wheel is installed on the adjusting block. By adjusting the adjusting bolt, the adjusting block can be pressed radially inward, so that the adjustable tensioning wheel is pressed on the strands. By adjusting the pressing amount of the adjustable tensioning wheel, the function of adjusting the strand tension is achieved. In this solution, the number of fixed tensioning wheels, movable tensioning wheels and adjustable tensioning wheels depends on the number of strands.

[0006] As an optimization, the fixed tensioning frame is fixed with a threaded shaft coaxial with the rope closing shaft, the adjustable tensioning frame and the movable tensioning frame are both threadedly connected to the threaded shaft, and also includes a fixing device for fixing the adjustable tensioning frame and the movable tensioning frame. In this solution, the adjustable tensioning frame and the movable tensioning frame are both threadedly connected to the threaded shaft, so that by rotating the adjustable tensioning frame and the movable tensioning frame, the distance between the fixed tensioning wheel group, the radially adjustable tensioning wheel group and the movable tensioning wheel group can be adjusted, and after the adjustment is completed, the fixing is achieved by the fixing device.

[0007] As an optimization, the fixing device includes a plurality of pull rods, which pass through the fixed tensioning frame, the adjustable tensioning frame and the movable tensioning frame. The pull rods in this solution pass through the fixed tensioning frame, the adjustable tensioning frame and the movable tensioning frame, thereby preventing the adjustable tensioning frame and the movable tensioning frame from rotating.

[0008] As an optimization, the rope closing shaft and the fixed tensioning wheel assembly are both provided with a steel wire passing hole coaxial with the rope closing shaft.

[0009] As an optimization, a locking nut is mounted on the adjusting bolt, and the locking nut in this solution prevents the adjusting bolt from loosening.

[0010] As an optimization, the fixed tensioning frame is fixedly connected to the rope closing shaft by bolts. In this solution, the fixed tensioning frame is fixedly connected to the rope closing shaft by bolts, thereby facilitating the disassembly and assembly of the fixed tensioning wheel set.

[0011] As an optimization, the fixed tension wheel, the adjustable tension wheel and the movable tension wheel are all U-shaped groove wheels. In this solution, they are arranged as U-shaped groove wheels, which is convenient for guiding the strands.

[0012] A tension control method using a tension control device comprises the following steps:

[0013] a. The strands passing through the rope shaft are guided by the inner side of the fixed tension wheel, and then guided by the outer side of the movable tension wheel and enter the die;

[0014] b. By adjusting the adjusting bolt, the adjusting block is pressed radially inward, so that it is pressed on the strand through the adjustable tension wheel. The high elasticity of the C steel rope is used to bend and deform through the adjustable tension wheel to generate bending positive stress to provide damping tension. By adjusting the pressing amount of the adjustable tension wheel, the function of adjusting the strand tension is achieved;

[0015] c. By adjusting the pressing amount of each adjustable tension wheel, the tension of each strand is equal, and equal tension rope twisting is achieved, that is, each strand is twisted synchronously;

[0016] d. By adjusting the distance between the fixed tension wheel group, the radially adjustable tension wheel group and the movable tension wheel group, it can adapt to different strand diameters and adjust the strand tension at the same time.

[0017] The beneficial effects of the present invention are as follows: the tension control device and tension control method for the C steel rope D-type rope making machine of the present invention provide sufficient damping tension for the correction process through the device. The outer skin of each strand of the C steel rope is a plastic braid made of PP or PE material, and a large tension damping cannot be directly adopted for it, otherwise it is easy to be damaged. The device uses the high elasticity of the C steel rope to bend and deform after passing through a small diameter wheel to generate a bending positive stress to provide sufficient damping tension. The device can also adjust the tension of each strand to be equal, and realize equal tension rope twisting, that is, synchronous rope twisting of each strand. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0025] like Figures 1 to 4 As shown, the tension control device for the C steel rope D type rope making machine of the present invention comprises a fixed tension wheel group 2, a radially adjustable tension wheel group 3 and a movable tension wheel group 4 which are fixedly connected to the discharge side of the rope closing shaft 1 in sequence along the discharge direction. The rope closing shaft 1 is provided with a plurality of rope closing holes 10 arranged along the circumferential direction. In this embodiment, the number of the rope closing holes 10 is 6. The strands 7 pass through the rope closing holes 10 and enter the die opening 9. The rope closing shaft 1 is fixed to one end of the rotating main shaft. Through the rotation of the rope closing shaft 1, the strands 7 are made into ropes in the die opening 9. The die opening 9 is fixed to a die opening frame 12. The fixed tension wheel group 2, the radially adjustable tension wheel group 3 and the movable tension wheel group 4 are all located between the rope closing shaft 1 and the die opening 9.

[0026] The fixed tensioning wheel group 2 includes a fixed tensioning frame 21 fixedly connected to the rope closing shaft 1 and a plurality of fixed tensioning wheels 22 installed on the fixed tensioning frame 21 along the circumference of the rope closing shaft 1. In this embodiment, six fixed tensioning wheels 22 are provided. The fixed tensioning wheel 22 is axially connected to the fixed tensioning frame 21 and the rotating shaft is perpendicular to the axis of the rope closing shaft 1. The strand 7 passing through the rope closing hole 10 passes around the inner side of the fixed tensioning wheel 22. The fixed tensioning frame 21 is fixedly connected to the rope closing shaft 1 by bolts.

[0027] The movable tensioning wheel group 4 includes a movable tensioning frame 41 fixed to the rope closing shaft 1 and a plurality of movable tensioning wheels 42 installed on the movable tensioning frame 41 along the circumference of the rope closing shaft 1. In this embodiment, 6 movable tensioning wheels 42 are arranged. The movable tensioning wheel 42 is axially connected to the movable tensioning frame 41 and the rotating shaft is perpendicular to the axis of the rope closing shaft 1. The strand 7 passing through the inner side of the fixed tensioning wheel 22 bypasses the outer side of the movable tensioning wheel 42 and then enters the die opening 9.

[0028] The radially adjustable tensioning wheel group 3 includes an adjustable tensioning frame 31 fixedly connected to the rope closing shaft 1 and a plurality of adjustment blocks 32 arranged circumferentially along the rope closing shaft 1. In this embodiment, six adjustment blocks 32 are provided. The adjustment blocks 32 are radially slidably connected to the adjustable tensioning frame 31 along the rope closing shaft 1. A penetrating sliding opening is opened on the adjustable tensioning frame 31, and the adjustment blocks 32 are slidably connected in the sliding opening.

[0029] like Figure 4 As shown, the adjustable tensioning frame 31 is threadedly connected with an adjusting bolt 34 which is pressed against the outside of the adjusting block 32, and a locking nut is installed on the adjusting bolt 34. The outside here refers to the side away from the center. The adjusting block 32 is equipped with an adjustable tensioning wheel 33, which is axially connected to the adjusting block 32 and the rotating shaft is perpendicular to the axis of the rope closing shaft 1. The adjustable tensioning wheel 33 is located on the side of the strand 7 away from the central axis of the rope closing shaft 1, and the strand 7 is pressed downward toward the central axis of the rope closing shaft 1 through the adjustable tensioning wheel 33.

[0030] The fixed tension wheel 22, the adjustable tension wheel 33 and the movable tension wheel 42 are all the same in size and shape and are all U-shaped groove wheels.

[0031] A threaded shaft 5 coaxial with the rope closing shaft 1 is fixedly connected to the fixed tensioning frame 21. The threaded shaft 5 is fixedly connected to the side of the fixed tensioning frame 21 away from the rope closing shaft 1. The outer side of the threaded shaft 5 is processed with a trapezoidal external thread. The center of the adjustable tensioning frame 31 and the center of the movable tensioning frame 41 are both processed with a trapezoidal internal thread. The adjustable tensioning frame 31 and the movable tensioning frame 41 are both threadedly connected to the threaded shaft 5, so that the distance between the fixed tensioning wheel group, the radially adjustable tensioning wheel group and the movable tensioning wheel group can be adjusted.

[0032] The distance between each strand 7 passing around the fixed tension wheel 22 and the movable tension wheel 42 is the roller distance (T), and the diameter of the fixed tension wheel 22 and the movable tension wheel 42 is the roller diameter (D). The roller distance (T) value is adjusted according to the diameter of the strand. When the diameter of the strand changes from small to large, the roller distance (T) value needs to be adjusted to gradually increase. If the T value is too small, the strand may be locked (not moving the rope), damaging the equipment; when the T value is too large, the strand tension is small or has no tension. The T value is a reasonable value when the strand can build tension and can meet the requirements of the correction process. The tension of the strand can be adjusted by adjusting the downward amount of the adjustable tension wheel 33. The greater the downward amount, the greater the tension value generated by the strand.

[0033] It also includes a fixing device for fixing the adjustable tensioning frame 31 and the movable tensioning frame 41, and the fixing device includes a plurality of pull rods 11, and the pull rods 11 pass through the fixed tensioning frame 21, the adjustable tensioning frame 31 and the movable tensioning frame 41. The pull rods 11 in this embodiment are screws, and the pull rods 11 are threadedly connected to the threaded holes of the fixed tensioning frame 21. The adjustable tensioning frame 31 and the movable tensioning frame 41 are provided with pull rod holes for accommodating the pull rods 11 to pass through.

[0034] The rope closing shaft 1 and the fixed tensioning wheel group 2 are both provided with a steel wire passing hole coaxial with the rope closing shaft 1. When the third steel rope 8 is processed, the central steel wire rope 6 passes through the steel wire passing hole and enters the die opening 9.

[0035] A tension control method using a tension control device comprises the following steps:

[0036] a rope shaft 1 through the strands 7 through the inner guide of the fixed tension wheel 22, through the outer guide of the movable tension wheel 42 into the die 9;

[0037] b. By adjusting the adjusting bolt 34, the adjusting block 32 is pressed radially inward, so that the adjusting block 32 is pressed on the strand 7 through the adjustable tensioning wheel 33. By utilizing the high elasticity of the steel rope C, the steel rope is bent and deformed through the adjustable tensioning wheel 33 to generate a bending positive stress to provide a damping tension. By adjusting the amount of depression of the adjustable tensioning wheel 33, the tension of the strand 7 is adjusted.

[0038] c. By adjusting the amount of depression of each adjustable tension wheel 33, the tension of each strand is equal, and equal tension rope twisting is achieved, that is, each strand is twisted synchronously;

[0039] d. By adjusting the distance between the fixed tension wheel set 2, the radially adjustable tension wheel set 3 and the movable tension wheel set 4, the different diameters of the strands 7 can be adapted, and the tension of the strands 7 can be adjusted at the same time.

[0040] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention.
