Description

Technical Field

[0001] The utility model relates to the technical field of rope making machines, and specifically refers to a traction and twisting mechanism of a high-speed rope making machine. Background Art

[0002] For a rope making machine to achieve rope twist, the rope making machine must have independent motors for traction and twisting. During operation, the rope cradle rotates. In traditional rope making machines, the traction motor is installed on the rope cradle. To achieve power supply, only a conductive slip ring can be used to conduct electricity into the rope cradle of the rope making machine. This structure has certain disadvantages: the conductive slip ring has a service life, and it is relatively troublesome to replace the conductive slip ring. To avoid this disadvantage, a new control structure needs to be developed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a traction and twisting mechanism of a high-speed rope making machine.

[0004] The utility model is realized through the following technical solutions. A traction and twisting mechanism of a high-speed rope making machine is provided, which includes a rope cradle and at least two traction wheel shafts axially connected to the rope cradle. Traction wheels are fixedly connected to the traction wheel shafts. Input end rotating shafts and output end rotating shafts coaxial with each other are fixedly connected to both ends of the rope cradle respectively. An input hole is opened in the center of the input end rotating shaft, and an output hole is opened in the center of the output end rotating shaft. A central gear is sleeved on the output end rotating shaft, and a planetary gear meshing with the central gear is fixedly connected to the traction wheel shaft. The rope cradle driving mechanism for driving the rope cradle to rotate around the axis of the output end rotating shaft and the traction driving mechanism for driving the central gear to rotate are further included.

[0005] In this solution, the output end rotating shaft drives the rope cradle to rotate. Multiple strands of wire are input from the input hole, repeatedly bypass the traction wheels, and finally output from the output hole. Twisting is achieved through the rotation of the rope cradle. The traction driving mechanism drives the central gear to rotate. The central gear drives the traction wheels to rotate through the planetary gears. When the rotation speed of the central gear is different from that of the output end rotating shaft, the traction wheels rotate due to the speed difference, thereby realizing the traction power.

[0006] As an optimization, the rope cradle driving mechanism includes a rope cradle motor and a rope cradle driven pulley fixedly connected to the output end rotating shaft, and a rope cradle driving pulley is installed on the rope cradle motor. In this solution, the rope cradle motor drives the output end rotating shaft to rotate through a synchronous belt.

[0007] As an optimization, the traction driving mechanism includes a traction motor and a traction driven pulley fixedly connected to the central gear, and a traction driving pulley is installed on the traction motor. In this solution, the traction motor drives the central gear to rotate through a synchronous belt.

[0008] As an optimization, one end of the input end rotating shaft close to the output end rotating shaft is pivotally connected with a first wire guiding wheel, and the outer circle of the first wire guiding wheel is tangent to the axis of the input hole. The first wire guiding wheel in this solution turns the wire rope by about 90 degrees, making it face the traction wheel.

[0009] As an optimization, one end of the output end rotating shaft close to the input end rotating shaft is pivotally connected with a second wire guiding wheel, and the outer circle of the second wire guiding wheel is tangent to the axis of the output hole. The second wire guiding wheel in this solution turns the wire rope output by the wire guiding wheel by about 90 degrees, making it face the output hole.

[0010] As an optimization, multiple wire grooves are formed on the traction wheel. The wire grooves in this solution improve the friction with the wire rope, facilitating traction.

[0011] As an optimization, the input end rotating shaft is pivotally connected to the input end bearing seat, and the output end rotating shaft is pivotally connected to the output end bearing seat. The rotation supports of the input end rotating shaft and the output end rotating shaft are realized through the two bearing seats.

[0012] As an optimization, two traction wheel shafts are provided and are circumferentially distributed evenly along the rotation axis of the wire cradle. The wire rope repeatedly bypasses the two traction wheels.

[0013] The beneficial effects of the present utility model are as follows: For the traction and twisting mechanism of a high-speed rope making machine of the present utility model, the motor is placed outside the wire cradle, and the planetary gear transmission principle is adopted. The speed difference generated by the cooperation of the power of the two motors forms the traction speed. By directly inputting the twist value through the PLC, when the rotation speed of the wire swing arm remains unchanged, the twist is changed by changing the linear speed of the traction. The two motors automatically calculate the required linear speed, thereby realizing twisting and traction. Description of the Drawings

[0017] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific embodiments.

[0018] Such as Figure 1As shown in the figure, a traction and twisting mechanism of a high-speed rope making machine of the present utility model includes a rope cradle 1. The two ends of the rope cradle 1 are respectively fixedly connected with a coaxial input end rotating shaft 4 and an output end rotating shaft 8. The input end rotating shaft 4 is pivotally connected to the input end bearing seat 6, and the output end rotating shaft 8 is pivotally connected to the output end bearing seat 10, thereby realizing the rotary support of the rope cradle 1.

[0019] An input hole 5 is opened in the center of the input end rotating shaft 4. The input hole 5 is a through-round hole and is coaxial with the input end rotating shaft 4. Multiple strands of wire pass through the input hole 5, and twisting is realized through the rotation of the rope cradle 1.

[0020] An output hole 9 is opened in the center of the output end rotating shaft 8. The output hole 9 is a through-round hole and is coaxial with the output end rotating shaft 8. The twisted rope is output from the output hole 9.

[0021] It further includes at least two traction wheel shafts 2 pivotally connected to the rope cradle 1. The two ends of the traction wheel shafts 2 are respectively supported on the rope cradle 1 through bearings. The axis of the traction wheel shafts 2 is parallel to the rotation axis of the rope cradle 1. There are two traction wheel shafts 2 and they are circumferentially evenly distributed along the rotation axis of the rope cradle 1.

[0022] A traction wheel 3 is fixedly connected to the traction wheel shaft 2. Multiple turns of rope grooves are opened on the traction wheel 3. The rope reciprocally winds around the two traction wheels 3, and traction is realized through the self-rotation of the traction wheels.

[0023] One end of the input end rotating shaft 4 close to the output end rotating shaft 8 is pivotally connected with a first wire guiding wheel 7. The axis of the first wire guiding wheel 7 is perpendicular to the axis of the input end rotating shaft 4. The outer circle of the first wire guiding wheel 7 is tangent to the axis of the input hole 5. The first wire guiding wheel 7 turns the rope by about 90 degrees so that it faces the traction wheel.

[0024] One end of the output end rotating shaft 8 close to the input end rotating shaft 4 is pivotally connected with a second wire guiding wheel 11. The axis of the second wire guiding wheel 11 is perpendicular to the axis of the output end rotating shaft 8. The outer circle of the second wire guiding wheel 11 is tangent to the axis of the output hole 9. The second wire guiding wheel 11 turns the rope output from the wire guiding wheel by about 90 degrees so that it faces the output hole.

[0025] In order to realize the rotation of the rope cradle 1 and the self-rotation of the traction wheel 3, a central gear 12 is sleeved on the output end rotating shaft 8. The central gear 12 is coaxial with the output end rotating shaft 8 and the relative rotation of the two is realized through bearings. A planetary gear 13 meshing with the central gear 12 is fixedly connected to the traction wheel shaft 2. The planetary gears 13 of the two traction wheel shafts 2 have the same diameter, so the rotation speeds of the two traction wheels are the same.

[0026] It further includes a rope cradle driving mechanism for driving the rope cradle 1 to rotate around the axis of the output end rotating shaft 8. The rope cradle driving mechanism includes a rope cradle motor 14 and a rope cradle driven pulley 16 fixedly connected to the output end rotating shaft 8. A rope cradle driving pulley 15 is installed on the rope cradle motor 14. The rope cradle driving pulley 15 drives the rope cradle driven pulley 16 to rotate through a synchronous belt.

[0027] It further includes a traction driving mechanism for driving the central gear 12 to rotate. The traction driving mechanism includes a traction motor 17 and a traction driven pulley 19 fixedly connected to the central gear 12. A traction driving pulley 18 is installed on the traction motor 17. The traction driving pulley 18 drives the traction driven pulley 19 to rotate through a synchronous belt.

[0028] The usage method of the present utility model:

[0029] In this application, the rope cradle motor 14 drives the output end rotating shaft 8 to rotate through a synchronous belt, thereby driving the rope cradle 1 to rotate. Multiple strands of wire are input from the input hole 5, bypass the first wire guiding pulley 7, repeatedly bypass the two traction pulleys 3, and finally bypass the second wire guiding pulley 11 and are output from the output hole 9. Twisting is achieved through the rotation of the rope cradle 1.

[0030] The traction motor 17 drives the central gear 12 to rotate through a synchronous belt. The central gear 12 drives the traction pulley 3 to rotate through the planetary gear 13. When the rotational speed of the central gear 12 is different from that of the output end rotating shaft 8, the traction pulley 3 rotates due to the speed difference, thereby achieving the traction power.
