Description

Technical Field

[0001] This utility model relates to the field of wire rope braiding technology, and in particular to a foot-operated wire rope braiding device. Background Technology

[0002] Wire rope splicing is a connection process that involves interlacing and fixing strands of wire rope to form a secure loop or connection point. This process significantly improves the load-bearing capacity, service life, and safety of the wire rope through mechanical friction interlocking between the strands, and is widely used in heavy equipment handling scenarios such as lifting, construction, and ship anchoring. During wire rope splicing, the end of the wire rope is first divided into independent strands, each retaining its complete structure for interlacing. Then, the strands are crossed and threaded into the gaps between adjacent strands in a specific order to form an interlocking structure.

[0003] In existing technologies, when separating wire rope strands, the self-winding force of the wire rope is relatively large, and the gaps between the strands are small, making manual separation impossible. A tapered tool is needed to pass through the gaps between the strands, and then leverage is used to open them. Then, the remaining wire rope is passed through the gaps between the strands. Separating the strands requires continuous force to maintain separation, which can lead to fatigue and affect operational accuracy over long periods. Therefore, existing technologies for stranding wire ropes are difficult and typically require two people, resulting in low work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a foot-operated wire rope braiding device, which solves the problem of the difficulty in stranding operations when braiding wire ropes in existing technologies.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A foot-operated steel wire rope inserter includes a support frame, with a first pulley and a second pulley arranged horizontally on the top of the support frame; a foot-operated drive assembly is connected to the bottom of the support frame, and one end of the steel wire rope is connected to the foot-operated drive assembly, with the other end of the steel wire rope passing over the first and second pulleys and then connected to a load; a rotating beam is arranged between the first and second pulleys, with one end of the rotating beam movably connected to the top of the support frame, the other end of the rotating beam fixed to the steel wire rope, and a shuttle assembly connected to the middle of the rotating beam.

[0006] In this design, a foot-operated drive assembly is used to move the wire rope. During this movement, the rope segment located between the first and second pulleys moves horizontally, causing the rotating beam to rotate. The rotating beam then drives the shuttle assembly to move synchronously. The end of the shuttle assembly is inserted into the middle of the strands of the wire rope to be braided, thus achieving the stranding operation. This design utilizes foot strength to drive the shuttle assembly to insert into the wire rope, making the operation relatively labor-saving. After insertion, releasing the foot causes the wire rope to move in the opposite direction under the weight, returning to its original position, allowing for the next stranding operation, resulting in high work efficiency.

[0007] Furthermore, the foot pedal drive assembly includes a drive shaft, the two ends of which are rotatably connected to the bottom of the support frame via two first bearings; a foot pedal is connected to the side of the drive shaft, and a connecting lug is connected to the top of the drive shaft; a steel wire rope is connected to the connecting lug.

[0008] In this design, the foot pedal is used to rotate the drive shaft, and the connecting lug connected to the drive shaft pulls the steel wire rope downward, making the operation relatively effortless and convenient.

[0009] Furthermore, the shuttle assembly includes a pad plate, which is fixed in the middle of the rotating beam; one end of the movable connecting rod is rotatably connected to the pad plate, and the other end of the movable connecting rod passes through the limiting ring and is welded to the outer ring of the second bearing; the limiting ring is fixedly installed on the crossbar at the top of the support frame; the inner ring of the second bearing is interference-fitted with a shuttle head, and the end of the shuttle head has a flat conical structure.

[0010] In this design, the steel wire rope pulls the rotating beam to rotate, and the rotating beam drives the movable connecting rod to move through the pad plate. When the movable connecting rod moves, it drives the shuttle head to move synchronously to insert and braid the steel wire rope. The limiting ring can limit the movement direction of the movable connecting rod, so that it moves along the direction of the shuttle head insertion.

[0011] Furthermore, a handle with a straight structure is connected to the middle of the shuttle head; a handle support is connected to the side of the crossbar near the shuttle head; when the shuttle head is not working, the handle is supported on the handle support.

[0012] In this design, the shuttle head is rotatably connected to the movable connecting rod via a second bearing. The handle allows the shuttle head to rotate. When the shuttle head is inserted into the wire rope, rotating it increases the spacing between the strands, facilitating insertion. When the shuttle head is not in operation, the handle is placed on the handle support to prevent rotation.

[0013] Furthermore, a longitudinal bar is provided at the top of the support frame, which is supported at the bottom of the rotating beam and the pad; a stop bolt is installed at the end of the longitudinal bar near the shuttle head, which is used to limit the distance the pad moves.

[0014] Furthermore, positioning stiffeners are welded onto the support frame.

[0015] Furthermore, the support frame is made of angle steel; the angle steel at the top front end of the support frame has an opening for the shuttle head to pass through.

[0016] Furthermore, one end of the connecting steel wire rope of the rotating beam is equipped with a U-shaped buckle by bolts. The steel wire rope passes through the middle of the U-shaped buckle and is pressed and fixed to the rotating beam by bolts.

[0017] The beneficial effects of this utility model are: The foot-operated wire rope braiding device provided by this utility model allows for operation by stepping on a foot pedal, which rotates the drive shaft. Simultaneously, a connecting lug connected to the drive shaft pulls the wire rope, causing it to rotate. This rotation of the wire rope drives the shuttle head forward, inserting it into the middle of the strands of the wire rope to be braided, thus achieving the stranding operation. This design utilizes foot strength to insert the shuttle head into the wire rope, making operation more labor-saving and convenient. After insertion, releasing the foot causes the wire rope to move in the opposite direction under the weight, returning the shuttle head to its original position, allowing for the next stranding operation. This results in high work efficiency. Companies using this foot-operated wire rope braiding device can braid wire ropes themselves, saving costs. Attached Figure Description

For those skilled in the art, various changes are obvious as long as they fall within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0020] like Figure 1 and Figure 2 As shown, this embodiment provides a foot-operated wire rope splicing device, which solves the problem of difficult stranding operation during wire rope splicing in the prior art; specifically, it includes: Support frame 1, first pulley 6, second pulley 5, lifting weight 4, foot pedal drive assembly 3, wire rope 2, rotating beam 7 and shuttle assembly 8; The top of the support frame 1 is equipped with a first pulley 6 and a second pulley 5 arranged horizontally; the bottom of the support frame 1 is connected to a foot pedal drive assembly 3; such as Figure 3 As shown, the foot pedal drive assembly 3 is connected to one end of the steel wire rope 2, and the other end of the steel wire rope 2 passes over the first pulley 6 and the second pulley 5 and is connected to the load 4; a rotating beam 7 is provided between the first pulley 6 and the second pulley 5, one end of the rotating beam 7 is movably connected to the top of the support frame 1, the other end of the rotating beam 7 is fixed to the steel wire rope 2, and a shuttle assembly 8 is connected to the middle of the rotating beam 7.

[0021] The foot-operated drive assembly 3 includes a drive shaft 31, a first bearing 34, a foot pedal 32, and a connecting ear plate 33. Both ends of the drive shaft 31 are rotatably connected to the bottom of the support frame 1 via two first bearings 34. The foot pedal 32 is connected to the side of the drive shaft 31, and the connecting ear plate 33 is connected to the top of the drive shaft 31. A steel wire rope 2 is connected to the connecting ear plate 33. By stepping on the foot pedal 32, the drive shaft 31 is rotated, and the connecting ear plate 33, connected to the drive shaft 31, pulls the steel wire rope 2 downwards, making the operation relatively effortless and convenient.

[0022] like Figure 4As shown, the shuttle assembly 8 includes a pad 85, a movable connecting rod 81, a limiting ring 82, a second bearing 83, and a shuttle 84. The pad 85 is fixed to the middle of the rotating beam 7. One end of the movable connecting rod 81 is rotatably connected to the pad 85, and the other end of the movable connecting rod 81 passes through the limiting ring 82 and is welded to the outer ring of the second bearing 83. The limiting ring 82 is fixedly installed on the crossbar 11 at the top of the support frame 1. The shuttle 84 is interference-fitted into the inner ring of the second bearing 83, and the end of the shuttle 84 has a flat conical structure. The wire rope 2 pulls the rotating beam 7 to rotate, and the rotating beam 7 drives the movable connecting rod 81 to move through the pad 85. When the movable connecting rod 81 moves, it drives the shuttle 84 to move synchronously, inserting and braiding the wire rope. The limiting ring 82 can limit the movement direction of the movable connecting rod 81, so that it moves along the direction in which the shuttle 84 is inserted.

[0023] A handle 86 with a straight section is connected to the middle of the shuttle head 84; a handle support 88 is connected to the side of the crossbar 11 near the shuttle head 84. The shuttle head 84 is rotatably connected to the movable connecting rod 81 via the second bearing 83. The handle 86 can drive the shuttle head 84 to rotate. When the shuttle head 84 is inserted into the wire rope, rotating the shuttle head 84 increases the gap between the strands of the wire rope due to its flat conical structure, facilitating insertion. When the shuttle head 84 is not in operation, the handle 86 is placed on the handle support 88 to prevent the shuttle head 84 from rotating.

[0024] As a preferred embodiment, the second bearing 83 can also be replaced by a nut. The movable connecting rod 81 is welded to one side of the nut, and the shuttle head 84 is threaded into the inside of the nut and can rotate relative to the nut.

[0025] The top of the support frame 1 is also provided with a longitudinal rod 12, which is supported on the bottom of the rotating beam 7 and the pad 85; a stop bolt 87 is installed at the end of the longitudinal rod 12 near the shuttle head 84, which is used to limit the distance the pad 85 can move.

[0026] A positioning stiffener 13 is also welded onto the support frame 1.

[0027] The support frame 1 is made of angle steel; the angle steel at the top front end of the support frame 1 is provided with an opening 14 for the shuttle head 84 to pass through.

[0028] One end of the steel wire rope 2 connected to the rotating beam 7 is fitted with a U-shaped buckle 9 by bolts. The steel wire rope 2 passes through the middle of the U-shaped buckle 9 and is fixed to the rotating beam 7 by bolts.

[0029] The working principle of this embodiment is as follows: During operation, stepping on the foot pedal 32 rotates the drive shaft 31. Simultaneously, the connecting lug 33, connected to the drive shaft 31, pulls the steel wire rope 2. The movement of the steel wire rope 2 pulls the rotating beam 7, causing it to rotate. The rotating beam 7 moves the shuttle head 84 forward, inserting it into the middle of the strands of the steel wire rope to be braided, thus achieving the stranding operation. After insertion, releasing the foot pedal causes the steel wire rope 2 to move in the opposite direction under the weight 4, returning the shuttle head 84 to its original position, allowing for the next stranding operation. This method offers high work efficiency.
