Description

Technical Field

[0001] This invention relates to cable production equipment, and more specifically to an automatic cable pulling and cutting system. Background Technology

[0002] In the prior art, the automatic cable pulling and cutting system includes: a cutting device, a pulling drive device, and a reel storage device. The reel storage device is used to store the steel strand reels. A pulling drive device is installed on one side of the reel storage device. A cutting device is set next to the pulling drive device. The pulling drive device pulls the steel strand to the cutting device. The cutting device is used to cut the steel strand to obtain the required length of steel strand.

[0003] Although the above-mentioned automatic cable pulling and cutting system can cut the steel strand after pulling it out, it still has the following drawbacks: because the steel strand used to make the cable is heavy and there is a distance between the pulling drive equipment and the reel storage equipment, the steel strand is prone to falling between the pulling drive equipment and the reel storage equipment due to its weight, causing the steel strand to hit the ground, or the steel strand to move randomly when the pulling drive equipment stops pulling. Summary of the Invention

[0004] The present invention provides an automatic cable pulling and cutting system to solve the problem in the prior art where the steel strand moves arbitrarily when the pulling drive device stops pulling due to the weight of the steel strand.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention discloses an automatic cable pulling and cutting system, comprising: a cutting device, a pulling drive device, a reel storage device, and a wheeled support device; the reel storage device is used to store steel strand reels, the pulling drive device is installed on one side of the reel storage device, and the cutting device is arranged next to the pulling drive device, the pulling drive device pulls the steel strand for the cutting device, and the cutting device is used to cut the steel strand; a wheeled support device is installed between the pulling drive device and the reel storage device, and the wheeled support device provides a rotatable arc support surface for the steel strand located between the pulling drive device and the reel storage device.

[0006] Preferably, a wheeled lifting device is installed between the reel storage device and the wheeled support device. The wheeled lifting device is used to lift the steel strand located between the reel storage device and the wheeled support device.

[0007] Preferably, the wheel-type lifting device includes: a lower wheel, an upper wheel, a lifting frame, a rope-type lifting mechanism, and a mounting frame. The rope-type lifting mechanism is installed on the mounting frame, and the output end of the rope-type lifting mechanism is connected to the lifting frame. The lifting frame is equipped with an upper wheel and a lower wheel arranged vertically. Both the upper wheel and the lower wheel can rotate relative to the lifting frame, and steel strands are clamped between the upper wheel and the lower wheel.

[0008] Preferably, the lifting frame includes a lifting base and a height adjustment unit. The lifting base is equipped with a rotatable upper wheel, the lifting base is equipped with a height adjustment unit that can be raised and lowered, and the height adjustment unit is equipped with a rotatable lower wheel.

[0009] Preferably, the height adjustment unit is connected to the first end of a rotating arm, and a rotatable lower wheel is mounted on the second end of the rotating arm. The direction of rotation of the rotating arm relative to the height adjustment unit is parallel to the horizontal plane.

[0010] Preferably, a rotating positioning part is installed on the lifting base. The rotating positioning part is used to move away from the rotating arm when the lower wheel separates from the upper wheel, and to restrict the rotation of the rotating arm when the lower wheel and the upper wheel approach each other and clamp the steel strand.

[0011] Preferably, a movable arm is installed on the height adjustment unit. The movable arm can move relative to the height adjustment unit in a direction away from or close to the rotating arm.

[0014] Preferably, the wheeled support device includes: a support base and a support wheel, wherein the support base is mounted with a rotatable support wheel, and the support wheel provides a rotatable arc support surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In this application, by setting a wheeled support device, the steel strand located between the traction drive device and the reel storage device is supported by the wheeled support device, which avoids the steel strand between the traction drive device and the reel storage device from having a downward trend due to excessive weight of the steel strand, and avoids the steel strand from detaching due to excessive weight of the steel strand during the traction drive device's cessation of traction, ensuring that the traction drive device always clamps the steel strand and can continuously pull out the steel strand.

[0016] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 7 As shown, this invention discloses an automatic cable pulling and cutting system, comprising: a cutting device 1, a traction drive device 2, a reel storage device 3, and a wheeled support device 4; the reel storage device 3 is used to store steel strand reels, the traction drive device 2 is installed on one side of the reel storage device 3, and the cutting device 1 is arranged next to the traction drive device 2, the traction drive device 2 pulls the steel strand for the cutting device 1, and the cutting device 1 is used to cut the steel strand; the wheeled support device 4 is installed between the traction drive device 2 and the reel storage device 3, and the wheeled support device 4 provides a rotatable arc support surface for the steel strand located between the traction drive device 2 and the reel storage device 3.

[0027] Optionally, the cutting device 1 includes: a cutting blade 11, a lifting drive mechanism 12, a cutting base 13, and a cutting frame 14. The cutting base 13 is installed on the side of the traction drive device 2 away from the wheeled support device 4. The cutting base 13 is spanned by the cutting frame 14, and the lifting drive mechanism 12 is installed on the cutting frame 14. The output end of the lifting drive mechanism 12 is fixed to the cutting blade 11, which is located directly above the cutting base 13. During cutting, the lifting drive mechanism 12 drives the cutting blade 11 to strike the steel strand located on the cutting base 13, thus cutting the steel strand to the target size. The lifting drive mechanism 12 can be a pneumatic cylinder or a hydraulic cylinder.

[0028] Optionally, the traction drive device 2 adopts a clamp-type traction to move the steel strand.

[0029] To prevent the steel strand from dragging on the ground, a wheeled lifting device 5 is installed between the reel storage device 3 and the wheeled support device 4. The wheeled lifting device 5 is used to lift the steel strand located between the reel storage device 3 and the wheeled support device 4. The steel strand is lifted by the wheeled lifting device 5 between the reel storage device 3 and the wheeled support device 4. After being lifted, the steel strand falls onto the wheeled support device 4, thus ensuring that the steel strand located between the traction drive device 2 and the reel storage device 3 has no tendency to fall. It also ensures that the steel strand at the wheeled support device 4 is relatively light and will not have a tendency to fall due to only providing a rotatable arc support surface.

[0030] To raise the steel strand using wheels, the wheel-type raising device 5 includes: a lower wheel 51, an upper wheel 52, a lifting frame 53, a rope-type raising mechanism 54, and a mounting frame 55. The rope-type raising mechanism 54 is mounted on the mounting frame 55, and the output end of the rope-type raising mechanism 54 is connected to the lifting frame 53. The upper wheel 52 and the lower wheel 51 are arranged vertically on the lifting frame 53. Both the upper wheel 52 and the lower wheel 51 can rotate relative to the lifting frame 53, and the steel strand is clamped between the upper wheel 52 and the lower wheel 51.

[0031] Optionally, the rope-type lifting mechanism 54 includes: a lifting rope 541, a guide pulley 542, a rope reel 543, and a rotation positioning mechanism 544. One end of the lifting rope 541 is fixed to the lifting frame 53, the middle of the lifting rope 541 passes over the guide pulley 542, and the other end of the lifting rope 541 is wound on the rope reel 543. Both the guide pulley 542 and the rope reel 543 can rotate relative to the mounting frame 55. The rotation positioning mechanism 544 is installed on the mounting frame 55 to limit the rotation of the rope reel 543. By pulling the lifting frame 53, the upper wheel 52, the lower wheel 51, and the steel strand with the lifting rope 541, the lifting mechanism reduces the pulling force of the steel strand. The pulling force of the steel strand is converted into the rotational force of the rope reel 543, reducing the burden on the lifting steel strand and improving the efficiency of lifting the steel strand.

[0032] Optionally, the rotary positioning mechanism 544 uses gears meshing with elastically movable tooth blocks to position the rope reel 543.

[0033] To adjust the distance between the upper wheel 52 and the lower wheel 51, the lifting frame 53 includes a lifting base 531 and a height adjustment unit 532. The upper wheel 52 is mounted on the lifting base 531, and the height adjustment unit 532 is also mounted on the lifting base 531. The lower wheel 51 is mounted on the height adjustment unit 532. By adjusting the position of the height adjustment unit 532 on the lifting base 531, the distance between the upper wheel 52 and the lower wheel 51 can be adjusted, facilitating the placement of the steel strand between them.

[0034] Optionally, the height adjustment unit 532 includes an adjusting screw ring 536 and a lifting ring 537. The adjusting screw ring 536 is threadedly connected to the lifting base unit 531. The lifting ring 537 is mounted on the adjusting screw ring 536. The adjusting screw ring 536 can move up and down relative to the lifting ring 537, and the adjusting screw ring 536 can drive the lifting ring 537 to move up and down. The lifting ring 537 cannot rotate relative to the lifting base unit 531. Since the steel strand cannot be rotated when it is placed between the rope pulley and the lower pulley 51, the lifting ring 537 cannot rotate. A rotating arm 533 and a moving arm 535 are mounted on the lifting ring 537 to prevent the steel strand from tangling due to the lifting ring 537, the lower pulley 51, and the upper pulley 52 driving the steel strand to rotate.

[0035] To allow the lower wheel 51 to rotate to a position offset from directly below the upper wheel 52, a height adjustment unit 532 is connected to the first end of a rotating arm 533. The rotating lower wheel 51 is mounted on the second end of the rotating arm 533, and the direction of rotation of the rotating arm 533 relative to the height adjustment unit 532 is parallel to the horizontal plane. By rotating the rotating arm 533, the lower wheel 51 can be rotated to a position offset from directly below the upper wheel 52. This allows the steel strand to be directly lifted by the arm and pushed below the upper wheel 52 without further pulling, which is difficult due to the weight of the steel strand. Once the steel strand is pushed below the upper wheel 52, rotating the lower wheel 51 downwards hooks the steel strand, reducing the effort required to install the steel strand between the upper and lower wheels 52 and improving the efficiency of the installation.

[0036] To ensure that the lower wheel 51 does not deviate from the upper wheel 52 after the steel strand is installed, a rotary positioning part 534 is installed on the lifting base 531. The rotary positioning part 534 is used to move away from the rotating arm 533 when the lower wheel 51 separates from the upper wheel 52, and to restrict the rotation of the rotating arm 533 when the lower wheel 51 approaches the upper wheel 52 and clamps the steel strand. Through the rotary positioning part 534, when the lower wheel 51 drives the steel strand to rise and is clamped at the upper wheel 52, the rotary positioning part 534 positions the rotating arm 533, preventing the rotating arm 533 from rotating arbitrarily. The rotary positioning part 534 allows a guide rod 538 to pass through, and the guide rod 538 is fixed to the lifting ring 537, thereby guiding the lifting ring 537 to rise and fall, and preventing the lifting ring 537 from rotating.

[0037] Optionally, the rotating positioning part 534 has a ring structure and is fixed to the lifting base part 531. The inner hole of the rotating positioning part 534 has a flared structure, with the upper part being larger than the lower part. The rotating positioning part 534 is used to position the rotating arm 533 and prevent the rotating arm 533 from flipping arbitrarily. To accommodate the shape of the inner hole of the rotating positioning part 534, a first part of the truncated cone surface is formed on the outer wall of the top of the rotating arm 533. The first part of the truncated cone surface guides the rotating arm 533 to slide into the inner hole of the rotating positioning part 534, thereby effectively positioning the rotating arm 533 and preventing the rotating arm 533 from rotating arbitrarily.

[0038] To improve the stability of the rotating arm 533 and extend its service life, a movable arm 535 is installed on the height adjustment unit 532. The movable arm 535 can move relative to the height adjustment unit 532 in a direction away from or towards the rotating arm 533. When the lower wheel 51 and the upper wheel 52 approach each other and clamp the steel strand, the movable arm 535 can be positioned by the rotation positioning unit 534 to support the second end of the rotating arm 533. The movable arm 535 can move to a position away from the second end of the rotating arm 533 to avoid obstructing the rotation of the rotating arm 533. The movable arm 535 can also move to a position close to the second end of the rotating arm 533 to support the second end of the rotating arm 533, thereby enabling the movable arm 535 to cooperate with the rotating arm 533 in supporting the steel strand, reducing the burden on the rotating arm 533, and extending its service life.

[0039] The rotary positioning part 534 has two effects: First, it positions the rotating arm 533, preventing the rotating arm 533 from causing the lower wheel 51 to deviate from the upper wheel 52. Second, it positions the movable arm 535. When the movable arm 535 approaches the rotating arm 533 (at which point the movable arm 535 supports the second end of the rotating arm 533), it can be positioned by the rotary positioning part 534, and the movable arm 535 will not move away from the rotating arm 533 after being positioned. The basis for the movable arm 535 being positioned by the rotary positioning part 534 is that the outer wall of the top end of the movable arm 535 forms a second part of a frustum-shaped cone. The second part of the frustum-shaped cone guides the movable arm 535 to slide into the inner hole of the rotary positioning part 534, thereby effectively enabling the rotary positioning part 534 to position the movable arm 535 and preventing the movable arm 535 from moving arbitrarily.

[0040] In this application, the steel strand coil storage device 3 includes a storage base 31 and a rotating seat 32. The storage base 31 is installed on the ground, and the rotating seat 32 is installed on the storage base 31. The rotating seat 32 is used to store the steel strand coil. The rotating seat 32 can rotate with the steel strand coil. If the friction between the steel strand coil and the rotating seat 32 is too large, the rotating seat 32 is provided to make the rotation smoother.

[0041] A central column 33 stands at the center of the rotating base 32, and the central column 33 passes through the center of the steel strand coil. The central column 33 positions the steel strand coil.

[0042] In this application, the wheeled support device 4 includes a support base 41 and a support wheel 42. The support base 41 is equipped with a rotatable support wheel 42, which provides a rotatable arc support surface. This allows the support wheel 42 to rotate when the steel strand moves, thereby ensuring that the steel strand can be pulled out smoothly.
