Description

Technical Field

[0001] This utility model relates to the technical field of anti-torsion devices, specifically to an anti-torsion device for steel wire ropes. Background Technology

[0002] Wire rope is a helical bundle of steel wires that meet the requirements of mechanical properties and geometric dimensions, twisted together according to certain rules. In material handling machinery, it is used for lifting, traction, tensioning, and load bearing.

[0003] Because of the spiral structure of the wire rope, when the wire rope is under stress, internal forces will be generated between the layers of wires and strands. Therefore, during hoisting operations, when the wire rope is subjected to tension, these internal forces can be decomposed into axial components parallel to the wire rope axis and radial components perpendicular to the wire rope axis. The radial component will cause the strands or wire rope to twist. Furthermore, the ends of the wire rope are usually fixed during hoisting. This fixing method restricts the free rotation of the wire rope, resulting in the internal torque not being released, which further aggravates the twisting phenomenon. This leads to severe twisting of the wire rope, cracks, breakage, and other phenomena, affecting its service life and safety.

[0004] In summary, existing wire ropes have the problem of being difficult to adjust due to twisting during hoisting. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-torsion device for wire ropes to solve the technical problem that most existing wire ropes are prone to torsion during hoisting operations.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] An anti-torsion device for steel wire ropes.

[0008] The device includes a protective housing, a first gear disc rotatably mounted on the inner bottom of the protective housing, a traction hook for installing a wire rope movably mounted on the bottom of the protective housing and connected to the first gear disc, a second gear disc rotatably mounted on the inner bottom of the protective housing and meshing with the first gear disc, symmetrically distributed positioning rods rotatably mounted on the inner bottom of the protective housing and located on one side of the first gear disc, side plates symmetrically mounted on the inner bottom of the protective housing to match the positioning rods, positioning springs connected to the positioning rods on the side walls of the side plates, and a double-headed cylinder between the two sets of positioning rods.

[0019] 1. In this utility model, the positioning spring provides elastic support to the positioning rod, and the two sets of positioning rods restrict the forward and reverse rotation of the No. 1 gear. When the wire rope twists, the extension and retraction of the telescopic rods at both ends of the double-headed cylinder are controlled according to the twisting direction, thereby releasing the rotation restriction of the No. 1 gear. The servo motor drives the No. 2 gear, which in turn drives the No. 1 gear, the hook, and the wire rope to rotate, effectively preventing the wire rope from twisting during use and improving safety and efficiency. After the adjustment is completed, the extended end of the double-headed cylinder is retracted, and at this time, a set of positioning rods repositions the No. 1 gear, thus ensuring that the No. 1 gear will not rotate with the wire rope after the adjustment is completed, ensuring the stability of the wire rope during hoisting.

[0020] 2. In this utility model, the combination design of the pull shaft, positioning block, return spring and fixing pin realizes the quick fixing and release of the packaging base, which facilitates the maintenance and repair of the device. Attached Figure Description

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0027] like Figure 1-3 As shown, an anti-torsion device for wire ropes is described.

[0028] The system includes a protective housing 1, a first gear 3 rotatably mounted on the inner bottom of the protective housing 1, a traction hook 4 movably mounted on the bottom of the protective housing 1 and connected to the first gear 3 for installing a wire rope, a second gear 5 rotatably mounted on the inner bottom of the protective housing 1 and meshing with the first gear 3, symmetrically distributed positioning rods 8 rotatably mounted on the inner bottom of the protective housing 1, with the positioning rods 8 located on one side of the first gear 3, and symmetrically arranged side plates 9 matching the positioning rods 8 on the inner bottom of the protective housing 1, with positioning devices connected to the positioning rods 8 on the side walls of the side plates 9. A double-headed cylinder 11 is installed between the spring 10 and the two sets of positioning rods 8. The protective housing 1 serves as the main support structure of the entire device, providing installation positions for other structures and ensuring their stability during use. A first gear disc 3 and a second gear disc 5 are rotatably mounted at the bottom inner side of the protective housing 1, achieving free rotation through internal bearings. A hook 4 is used to install and fix the wire rope, ensuring that the wire rope can move with the rotation of the first gear disc 3. A servo motor 6 is installed at the top center of the second gear disc 5 as the drive source. The positioning spring 10 aligns with the positioning rods 8. The system provides elastic support. Without external force, the two sets of positioning rods 8 can limit the forward and reverse rotation of the first gear disc 3. When the wire rope twists, the operator can activate the servo motor 6. Based on the direction of the twist, the servo motor 6 drives the second gear disc 5 to rotate in the corresponding direction. At this time, the second gear disc 5 drives the first gear disc 3 to rotate as well. The first gear disc 3 drives the hook 4 to rotate, and the hook 4 drives the wire rope to rotate. This effectively prevents the wire rope from twisting. It should be noted that when driving the first gear disc 3 to rotate, the operator... Personnel need to control the extension and retraction of the telescopic rods at both ends of the double-headed cylinder 11 according to the rotation direction of the first gear 3. The extension of one end of the telescopic rod can compress the corresponding positioning rod 8, causing the positioning spring 10 to deform and be compressed. At this time, a set of positioning rods 8 deflects and releases the limitation on the rotation direction of the first gear 3. After the adjustment is completed, the extended end of the double-headed cylinder 11 is retracted. At this time, a set of positioning rods 8 repositions the first gear 3, thus ensuring that the first gear 3 will not rotate with the wire rope after the adjustment is completed, ensuring the stability of the wire rope during hoisting.

[0029] In this embodiment, specifically, the double-headed cylinder 11 is fixed to the bottom wall of the protective housing 1 by a clamp, which ensures the stability of the double-headed cylinder 11 during use.

[0030] In this embodiment, specifically, the top of the protective housing 1 is movably provided with an encapsulation base 2, and the bottom of the encapsulation base 2 is provided with a protrusion, the outer wall of the protrusion being in contact with the inner wall of the protective housing 1.

[0031] In this embodiment, specifically, a servo motor 6 is provided at the top center of the second gear disk 5, and a fixed bracket 7 for supporting the servo motor 6 is provided on the side wall of the protective housing 1. The fixed bracket 7 provides suspension support for the servo motor 6, ensuring the stability of the servo motor 6 during use, so that the servo motor 6 can smoothly drive the second gear disk 5 to rotate, thereby realizing the torsion adjustment of the wire rope.

[0032] In this embodiment, specifically, four sets of equidistantly distributed positioning grooves 12 are provided on the outer wall of the protrusion, and a movable groove 13 matching the positioning grooves 12 is provided on the outer wall of the protective shell 1. A storage box 14 matching the movable groove 13 is provided on the outer wall of the protective shell 1, and the storage box 14 covers the movable groove 13. A pull shaft 15 is slidably arranged inside the storage box 14, and one end of the pull shaft 15 passes through the side wall of the storage box 14. A baffle is provided at the through end for easy manual operation. A positioning block 16 is provided at the other end of the pull shaft 15. A return spring 17 is sleeved on the outside of the pull shaft 15 and is located inside the storage box 14. Two sets of limiting holes 18 are provided through the pull shaft 15. A fixing pin 19 is sleeved inside one set of limiting holes 18 and is located on the outside of the storage box 14. The top outer edge of the encapsulation base 2 is opened with... Four sets of spaced fixing holes 20 are provided, and the fixing holes 20 are used to install bolts. Under the action of the return spring 17, the positioning block 16 is inserted into the positioning groove 12 opened on the outer wall of the protrusion, thereby realizing the assembly and fixation between the encapsulation base 2 and the protective shell 1. When it is necessary to disassemble the encapsulation base 2, the operator pulls out the fixing pin 19 and pulls the pull shaft 15 outward. The pull shaft 15 pulls the positioning block 16 out of the positioning groove 12. At this time, the positioning block 16 squeezes the return spring 17, and the return spring 17 is compressed. Then the fixing pin 19 is reinserted into another set of limiting holes 18 to fix the pull shaft 15, thereby completing the disassembly of the encapsulation base 2. When installing the encapsulation base 2, the encapsulation base 2 is installed at the predetermined position of the protective shell 1, and the fixing pin 19 is pulled out. The return spring 17 automatically resets when the pull shaft 15 is released.

[0033] In this embodiment, specifically, four sets of spaced fixing holes 20 are provided on the top outer edge of the encapsulation base 2 for installing bolts, so as to facilitate fixing the entire device to the relevant hoisting equipment.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
