Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire rope processing technology, and more specifically, to a multi-segment straightening device for wire rope. Background Technology
[0002] During the production, processing, and use of wire ropes, due to factors such as raw material characteristics, manufacturing processes, and subsequent handling and storage, wire ropes are prone to bending, twisting, and other deformations. This not only affects their appearance quality but also reduces their strength, toughness, and other mechanical properties, shortens their service life, and may even pose safety hazards during use. Although some wire rope straightening equipment exists on the market, most can only straighten single sections. When faced with complex deformations or multiple sections of wire rope with varying degrees of deformation, the straightening effect is poor and the efficiency is low, making it difficult to meet the needs of high-quality production and diverse application scenarios.
[0003] A search revealed Chinese patent CN210115414U, which discloses a wire rope straightening device. This utility model features a planar straightening wheel assembly and a vertical straightening wheel assembly with straightening wheels arranged in a single row. The wire rope is wound in an S-shape around the straightening wheels at any position for straightening. The right-angled planar and vertical straightening wheel assemblies can straighten the wire rope from all directions, eliminating internal stress. The straightening frame uses simple right-angled square steel, facilitating compatibility with electric suspended platforms, hoists, and lifting equipment.
[0004] Although the above-designed wire rope straightening device uses planar and vertical straightening wheel sets to achieve multi-segment straightening, in actual use, both the planar and vertical straightening wheel sets are installed on the same horizontal line, i.e., a single-line structure. This occupies a large amount of space in actual use. Furthermore, the actual U-shaped guide groove is placed at the initial insertion end of the wire rope. Since the wire rope itself has bent and deformed parts, it is very easy for the wire rope to detach from the U-shaped guide groove during the straightening process, thus causing it to deviate from the planar straightening wheel. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a multi-segment straightening device for steel wire rope.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-segment straightening device for steel wire rope, comprising a support base, with a support adjustment mechanism installed at each of the four corners of the support base, a first support frame fixedly connected to the top of the support base, a first mounting horizontal plate fixedly connected to the top of the first support frame, a second support frame fixedly connected to the top of the first mounting horizontal plate, a second mounting horizontal plate fixedly connected to the top of the second support frame, a limiting seat fixedly provided at the top of one end of the second mounting horizontal plate, a limiting mechanism provided at the top of the limiting seat, a plurality of planar straightening wheels for steel wire rope winding equidistantly installed at the top of the second mounting horizontal plate along the horizontal direction, and a protruding plate fixedly connected to the other end of the second mounting horizontal plate, with a steering straightening wheel connected to the outer wall of the protruding plate, a plurality of vertical straightening wheels for steel wire rope winding connected to the outer wall of the first mounting horizontal plate along the horizontal direction, and a traction machine for traction wire rope winding installed at the bottom of the support base near the limiting seat.
[0007] As a further improvement to the technical solution of this utility model, the support adjustment mechanism includes a fixed cylinder fixedly connected to the bottom of the support base. A stud is connected vertically inside the fixed cylinder. A handwheel is fixedly connected to the top of the stud extending above the support base, and a support foot is fixedly connected to the bottom of the stud below the fixed cylinder.
[0008] As a further improvement to the technical solution of this utility model, the inside of the fixed cylinder is provided with an internal thread hole that matches the external thread structure of the stud, and the stud and the fixed cylinder are connected by threads.
[0009] As a further improvement to the technical solution of this utility model, the connection between the handwheel and the support foot and the upper and lower ends of the stud is welded, and the support base is provided with a through hole for the stud to pass through.
[0010] As a further improvement to the technical solution of this utility model, the limiting mechanism includes a through slot on the top of the limiting seat for the wire rope to pass through. The limiting seat has an arc-shaped cavity inside, and a movable block is provided inside the arc-shaped cavity. A spring is connected between one end of the movable block and the inner wall of the end of the arc-shaped cavity, and an arc-shaped rod with the same arc center as the arc-shaped cavity is connected to the other end of the arc-shaped cavity. The end of the arc-shaped rod extends to the outside of the limiting seat, and a toggle block is fixedly provided on the top outer wall of the arc-shaped rod.
[0011] As a further improvement to the technical solution of this utility model, the top of the limiting seat is provided with a limiting groove for the end of the arc-shaped rod to be inserted.
[0012] As a further improvement to the technical solution of this utility model, the bottom of the traction machine and the top of the support base are fixedly connected by bolts, and the bottom of the second mounting plate is provided with a control switch for driving the motor on the traction machine.
[0013] The beneficial effects of this utility model are:
[0014] 1. Compared with the single-line straightening structure, the reciprocating straightening structure adopted by this utility model occupies less space. The support adjustment mechanism is set in it so that the support height can be adjusted as needed during use. It can also avoid large vibration amplitude caused by uneven placement surface during the straightening process, which can cause instability. During operation, the stud is driven to rotate by turning the handwheel. The stud is connected to the internal thread in the fixed cylinder. When rotating, the stud can be adjusted up and down inside the fixed cylinder.
[0015] 2. By setting a limiting mechanism on the top of the limiting seat, the operator only needs to pull the actuating block to drive the arc-shaped rod to rotate and gradually retract into the arc-shaped cavity. At this time, the spring is compressed, and the operator can place the wire rope inside the slot. Then, release the actuating block, and under the push of the spring's reset, one end of the arc-shaped rod is inserted into the limiting slot, thereby closing the slot. This facilitates the limiting treatment of the wire rope passing through during use, so that the wire rope at the initial entry end will not deviate from the plane straightening wheel.

Support adjustment mechanisms are installed at the four corners of the support base 1. A first support frame 2 is fixedly connected to the top of the support base 1.

Several planar straightening wheels 6 for wire rope winding are equidistantly installed at the top of the second mounting plate 5 along the horizontal direction. A protruding plate 8 is fixedly connected to the other end of the second mounting plate 5. A steering straightening wheel 9 is connected to the outer wall of the protruding plate 8. Several vertical straightening wheels 10 for wire rope winding are connected to the outer wall of the first mounting plate 3 along the horizontal direction. A traction machine 11 for traction wire rope winding is installed at the bottom of the support base 1 near the limiting seat 7.
[0023] As attached Figure 1-3 As shown, the support adjustment mechanism includes a fixed cylinder 12 fixedly connected to the bottom of the support base 1. A stud 13 is connected vertically inside the fixed cylinder 12. The top end of the stud 13 extends to the top of the support base 1 and is fixedly connected to a handwheel 14. The bottom end of the stud 13 is located below the fixed cylinder 12 and is fixedly connected to a support foot 15. The fixed cylinder 12 has an internal threaded hole 121 that matches the external thread structure of the stud 13. The stud 13 and the fixed cylinder 12 are connected by threads. The handwheel 14 and the support foot 15 are connected to the upper and lower ends of the stud 13 by welding. The support base 1 has a through hole 101 for the stud 13 to pass through, which facilitates the adjustment of the support height as needed during use and can also prevent large vibration amplitude caused by uneven placement surface during straightening, thus avoiding placement instability.
[0024] As attached Figure 1 and attached Figure 4As shown, the limiting mechanism includes a through slot 701 on the top of the limiting seat 7 for the wire rope to pass through. The limiting seat 7 has an arc-shaped cavity 702 inside, and a movable block 703 inside the arc-shaped cavity 702. A spring 704 is connected between one end of the movable block 703 and the inner wall of the end of the arc-shaped cavity 702, and an arc-shaped rod 705 with the same arc center as the arc-shaped cavity 702 is connected to the other end of the arc-shaped cavity 702. The end of the arc-shaped rod 705 extends to the outside of the limiting seat 7, and a toggle block 707 is fixedly installed on the top outer wall of the arc-shaped rod 705. The top of the limiting seat 7 has a limiting slot 706 for the end of the arc-shaped rod 705 to be engaged. The limiting mechanism facilitates the limiting treatment of the wire rope passing through during use, so that the wire rope at the initial entry end will not deviate from the plane straightening wheel 6.
[0025] As attached Figure 1 As shown, the bottom of the traction machine 11 is fixedly connected to the top of the support base 1 by bolts, and the bottom of the second mounting plate 5 is provided with a control switch for driving the motor on the traction machine 11.
[0026] Working principle: This utility model designs a multi-segment straightening device for steel wire ropes, the specific structure of which is shown in the attached instruction manual. Figure 1-4 As shown, in use, the wire rope passes through the top of the limiting seat 7, then winds around the outside of multiple planar straightening wheels 6 in sequence, and winds around to the outside of multiple vertical straightening wheels 10 via the steering straightening wheel 9. By controlling the motor on the traction machine 11, the traction machine 11 generates tension, gradually straightening and winding the wire rope at multiple positions. The reciprocating structure occupies less space than the single-line type. The support adjustment mechanism allows for easy adjustment of the support height as needed during use, and can also prevent large vibration amplitudes caused by uneven placement surfaces during straightening, thus avoiding instability. During operation, the handwheel 14 is turned to drive the stud 13 to rotate, and the stud 13 and the inner screw inside the fixed cylinder 12... The threaded connection 121 allows the stud 13 to be adjusted in height within the fixed cylinder 12 during rotation. Furthermore, by setting a limiting mechanism at the top of the limiting seat 7, the operator only needs to pull the actuating block 707 to rotate the arc-shaped rod 705 and gradually retract it into the arc-shaped cavity 702. At this time, the spring 704 is compressed. The operator can then place the wire rope inside the through-groove 701, and then release the actuating block 707. Under the reset push of the spring 704, one end of the arc-shaped rod 705 is inserted into the limiting slot 706, thereby closing the through-groove 701. This facilitates limiting the passage of the wire rope during use, preventing the initial entry end of the wire rope from deviating from the plane straightening wheel 6.
