Description

Technical Field

[0001] This utility model relates to the field of wire rope braiding technology, and in particular to a circular braiding machine for wire rope slings. Background Technology

[0002] Wire rope lock splicing is a technology specifically used for manufacturing or repairing wire rope end connection devices. High-quality splicing process can provide additional tensile strength while ensuring the original strength of the wire rope, enabling the wire rope lock to withstand greater working loads. Wire rope locks that have undergone professional splicing treatment have better wear resistance, extend service life, and reduce replacement frequency and maintenance costs.

[0003] Existing wire rope slings with circular braiding are made manually or using hand-pressed braiding machines, which have disadvantages such as low braiding efficiency, high labor intensity for workers, and unstable quality of finished slings. Chinese patent application number "2024211074559" discloses a wire rope braiding machine. The machine uses a motor to rotate a threaded rod, which in turn moves a sliding rod, causing the inserting knife to move. The inserting knife breaks apart the tangled wires of the wire rope. Then, a sliding groove slides on a sliding rod. The sliding rod rotates 90 degrees, causing the inserting knife to rotate, widening the gap. The inserting knife then continues to move downwards, causing the wire clamping groove to move. The movement of the wire slot drives a steel wire through the wire rope, realizing the insertion and braiding of the wire rope. This saves manpower, reduces labor costs, and improves work efficiency to a certain extent. However, the following defects still exist: the space provided by this equipment for placing the wire rope is limited, and the traditional insertion and braiding machine structure relies mainly on the insertion blade to support the gap between the wires. This results in the insertion blade occupying most of the space in the gap, which still causes inconvenience to workers. In addition, the position of the insertion blade and the wire rope is fixed. When the length, diameter, material, and insertion and braiding method of the wire are different, it is difficult to meet the specific application requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a circular braiding machine for wire rope slings, which breaks the tension of the wire rope by un-twisting, saves the labor of workers in inserting the blade and supporting the strand, has a large braiding operation space, can meet different application needs, improves the efficiency of braiding work, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A circular braiding machine for wire rope slings includes a frame, an operating table on one side of the frame, a lower fixing clamping device on the operating table, and an upper fixing clamping device above the lower fixing clamping device. The upper fixing clamping device is fixedly connected to the frame via a connecting plate. The operating table includes a support base, a retraction operating table rotatably connected to the support base, and a self-locking device on one side of the retraction operating table. The retraction operating table and the connecting plate both have recesses suitable for accommodating wire rope loops on the same side.

[0007] Furthermore, the lower fixed clamping device includes a first movable clamping part disposed on the untwisting operating table, a first operating rod connected to the first movable clamping part, and a first fixed clamping part disposed on the untwisting operating table. The first fixed clamping part and the first movable clamping part are symmetrically disposed on both sides of the recess of the untwisting operating table.

[0008] Furthermore, the upper fixing clamping device includes a second movable clamping part disposed on the un-twist operating table, a second operating rod connected to the second movable clamping part, and a second fixed clamping part disposed on the un-twist operating table. The second fixed clamping part and the second movable clamping part are symmetrically disposed on both sides of the recess of the connecting plate.

[0009] Furthermore, the un-twist operating table includes an upper platform, a lower platform located below the upper platform, and a plurality of support columns located between the upper platform and the lower platform. The two ends of each support column are fixedly connected to the upper platform and the lower platform, respectively. The lower platform is rotatably connected to a support base with its axis of rotation coinciding with the vertical axis of the support base.

[0010] Furthermore, a number of limiting grooves are provided on the edge of the lower platform, and the limiting grooves are symmetrically distributed along the rotation axis of the lower platform.

[0011] Furthermore, a self-locking device is provided on one side of the lower platform. The self-locking device includes a support frame, a locking member rotatably connected to the support frame, a stop block provided on one side of the locking member, and an elastic member provided on the stop block. The end of the elastic member away from the stop block is connected to the locking member. The locking member is provided with a limiting head at one end near the lower platform and a pedal at the other end. The shape of the limiting head matches the groove shape of the limiting groove. When the locking member is reset by the elastic deformation force of the elastic member, the limiting head is in the limiting groove.

[0012] The beneficial effects of this utility model are as follows: This utility model addresses the structural characteristics of circular braided wire rope slings by employing a untwisting method to break the tension of the wire rope sling to be braided. After the two ends of the sling to be braided are looped, one loop is clamped and fixed to the untwisting operating platform using a lower fixing clamping device, and the upper end is clamped using an upper fixing clamping device. Then, by stepping on the foot pedal of the foot-operated locking device, the platform is rotated in the opposite direction to untwise the wire rope to be braided. When the gap between the strands increases, the pedal is released, and the platform is rotated to lock. After braiding is completed, the self-locking device is opened, and the elastic deformation force of the wire rope restores the tight twisted state. This makes it more convenient for workers to braid wire ropes, saves labor for workers to insert the sling and support the strands, and provides a large braiding operating space to meet different application needs and improve braiding efficiency.

[0022] The following is an example:

[0023] A circular braiding machine for wire rope slings includes a frame 100. An operating table 200 is provided on one side of the frame 100. A lower fixing clamping device 300 is provided on the operating table 200, and an upper fixing clamping device 400 is provided above the lower fixing clamping device 300. The upper fixing clamping device 400 is fixedly connected to the frame 100 through a connecting plate 500. The operating table 200 includes a support base 210, a retraction operating table 220 rotatably connected to the support base 210, and a self-locking device 230 provided on one side of the retraction operating table 220. The retraction operating table 220 and the connecting plate 500 both have notches suitable for accommodating wire rope loops on the same side. The worker's braiding work area is located between the lower fixing clamping device 300 and the upper fixing clamping device 400. This layout provides the worker with a larger operating space for braiding.

[0024] As a further technical solution in this embodiment, the lower fixed clamping device 300 includes a first movable clamping part 310 disposed on the un-twist operating table 220, a first operating rod 320 connected to the first movable clamping part 310, and a first fixed clamping part 330 disposed on the un-twist operating table 220. The first fixed clamping part 330 and the first movable clamping part 310 are symmetrically disposed on both sides of the recess of the un-twist operating table 220. The first movable clamping part 310 includes a first linear guide mechanism 311, a first movable clamping end 312 mounted on the slider of the linear guide mechanism 311, and a first lead screw 313 threadedly connected to the slider of the linear guide mechanism 311. The first lead screw 313 and the first operating rod 320 are fixedly connected by a nut fastener.

[0025] As a further technical solution in this embodiment, the upper fixed clamping device 400 includes a second movable clamping part 410 disposed on the un-twist operating table 220, a second operating rod 420 connected to the second movable clamping part 410, and a second fixed clamping part 430 disposed on the un-twist operating table 220. The second fixed clamping part 430 and the second movable clamping part 410 are symmetrically disposed on both sides of the recess of the connecting plate 500. The second movable clamping part 410 includes a second linear guide mechanism 411, a second movable clamping end 412 mounted on the slider of the linear guide mechanism 411, and a second lead screw 413 threadedly connected to the slider of the linear guide mechanism 411. The second lead screw 413 and the second operating rod 420 are fixedly connected by a nut fastener.

[0026] As a further technical solution in this embodiment, the un-twist operating table 220 includes an upper table plate 221, a lower table plate 222 disposed below the upper table plate 221, and four support columns 223 disposed between the upper table plate 221 and the lower table plate 222. The two ends of each support column 223 are welded to the upper table plate 221 and the lower table plate 222 respectively. The lower table plate 222 is rotatably connected to the support base 210 through a bearing, and the rotation axis of the lower table plate 222 coincides with the vertical axis of the support base 210.

[0027] As a further technical solution in this embodiment, twelve limiting grooves 2221 are provided on the edge of the lower platform 222, and the limiting grooves 2221 are symmetrically distributed along the rotation axis of the lower platform 222.

[0028] As a further technical solution in this embodiment, a self-locking device 230 is provided on one side of the lower platform 222. The self-locking device 230 includes a support frame 231, a locking member 232 rotatably connected to the support frame 231, a stop block 233 provided on one side of the locking member 232, and an elastic member 234 provided on the stop block 233. The locking member 232 is a Z-shaped alloy tooling part, and the elastic member 234 is a tension spring. The end of the elastic member 234 away from the stop block 233 is connected to the locking member 232. The locking member 232 is provided with a limiting head 2321 at one end near the lower platform 222 and a pedal 2322 at the other end. The shape of the limiting head 2321 matches the groove shape of the limiting groove 2221. When the locking member 232 is reset by the elastic deformation force of the elastic member 234, the limiting head 2321 is in the limiting groove 2221.

[0029] When workers are performing the splicing operation, after the two ends of the rigging to be spliced ​​are looped, one wire rope strand loop is placed in the notch of the untwisting operating table 220 and clamped and fixed to the untwisting operating table 220 using the lower fixing clamping device 300. The other wire rope strand loop is placed in the notch of the connecting plate 500 and clamped using the upper fixing clamping device 400. Then, by stepping on the pedal 2322, the untwisting operating table 220 is rotated in the opposite direction of the wire rope strand twisting to reverse the direction of the splicing of the wire rope. When the gap between the wire rope strands increases, release the pedal 2322. The limiting head 2321 of the locking part 232 is in the limiting groove 2221 of the lower platform 222. The untwisting operation table 220 is locked. At this time, use a cutting tool or directly hold the small strands to insert them in the insertion sequence. After the wire rope strands are inserted, step on the pedal 2322. The untwisting operation table 220 restores the wire rope to a tight twisted state through the elastic deformation force of the wire rope strands, making the small strands of wire rope tightly inserted.

[0030] In summary, this utility model breaks the tension of the wire rope through a untwisting method, saving workers the labor of inserting the cutting tool and supporting the strands. It also provides a large insertion and braiding operation space, which can meet different application needs and improve the efficiency of insertion and braiding work.
