Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire rope twisting technology, and in particular relates to a wire rope twisting machine with an adjustable function for wire rope production. Background Technology
[0002] As a high-strength and high-toughness composite structural material, steel wire rope is widely used in many fields such as hoisting machinery, mining, bridge construction, and elevator manufacturing. Its performance is directly related to the safe operation and service life of related equipment.
[0003] To ensure that the diameter of the strands matches the subsequent rope-jointing process, guide dies with different apertures are used to compress several steel wires, making them in close contact with the rope core and adjacent steel wires, so that the final steel wire rope has dimensional accuracy in compliance with regulations. However, in actual operation, steel wire ropes of different diameters are produced, which requires frequent replacement of guide dies. During disassembly and assembly, workers need to use special tools, which consumes a lot of time, thus reducing the overall production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a wire rope twisting machine with an adjustable function. Specifically, by rotating the handle clockwise, the rotating rod rotates, and the two anti-detachment rings on its left end drive the adjusting ring to the left. The three adjusting blocks lose their compression and move away from each other under the elastic force of the three springs. Rotating the handle counterclockwise moves the adjusting ring to the right, compressing the three adjusting blocks and bringing them closer together. This adjusts the spacing between the three adjusting blocks. By using adjusting blocks with different spacings to compress the wire rope, the diameter can be controlled. This design offers high flexibility and significantly improves production efficiency. It solves the problem that existing wire rope twisting machines use guide molds to ensure dimensional accuracy, but this requires a significant amount of time to replace the guide molds when producing wire ropes of different diameters, leading to reduced production efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0012] Furthermore, a number of fixed seats are fixedly connected to the left side of the outer surface of the outer ring, and a rotating roller is rotatably connected to the ends of the fixed seats that are far apart from each other. A number of lifting rods are slidably limited to the right side of the outer surface of the outer ring, and a rotating roller is rotatably connected to the ends of the lifting rods that are far apart from each other. A fixed sliding rod is fixedly connected to the ends of the lifting rods that are close to each other.
[0013] The fixed seats and the lifting rods are in one-to-one correspondence, and several fixed seats and several lifting rods are distributed in a ring on the outer surface of the outer ring.
[0014] Furthermore, two fixing blocks are fixedly connected to the right side of the regulating tube, and a guide rod is fixedly connected to the left side of each of the two fixing blocks.
[0015] Both guide rods slide through the moving ring and extend to the outside. A second fixing block is fixedly connected to the right side of the adjusting tube. The two fixing blocks are distributed in a ring at equal intervals on the right side of the adjusting tube.
[0016] Furthermore, the fixing block two is internally threaded with a rotating rod, and a rotating handle one is fixedly connected to the right side of the rotating rod;
[0017] The outer surface of the throttle handle is slidably limited to the moving ring, and two anti-detachment rings are fixedly connected to the left end of the throttle rod. The two anti-detachment rings are used to pull the moving ring to move.
[0018] Furthermore, each of the three adjusting blocks is fixedly connected to a limiting rod on the side that is far apart from each other. A spring is sleeved on the outer surface of the limiting rod. One end of the spring is fixedly connected to the adjusting block, and the other end of the spring is fixedly connected to the inner wall of the adjusting tube.
[0019] The inner ring of the adjusting ring has an arc-shaped inclined surface that matches the left side of the adjusting block, and the three limiting rods are all in sliding limiting cooperation with the adjusting tube.

This design allows for flexible adjustment of the tension of the corresponding steel wire, ensuring sufficient tension when multiple steel wires are twisted together. This prevents the wires from breaking due to excessive force or becoming loose due to insufficient force.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0039] Please see Figures 1-7 As shown, this utility model is a wire rope production stranding machine with an adjustable function, including a base 1, a stranding machine 11 installed on the top left side of the base 1, an outer ring 31 provided on the top of the base 1, a support frame 211 fixedly connected to the top right side of the base 1, an adjusting pipe 21 fixedly connected to the top of the support frame 211, and also including:
[0040] A strand diameter adjustment mechanism 2 is located inside the adjustment tube 21. The strand diameter adjustment mechanism 2 is used to adjust the diameter of the wire rope and includes three adjustment blocks 25; and
[0041] Tension adjustment mechanism 3 is set on the outer surface and inside of outer ring 31. Tension adjustment mechanism 3 is used to adjust the tension of single strand steel wire. Among them, three adjustment blocks 25 are distributed in a ring inside the adjustment tube 21, and each of the three adjustment blocks 25 has an arc-shaped inclined surface on its left side.
[0042] The outer surface of the regulating tube 21 is fitted with a sliding ring 22, and the inner ring of the sliding ring 22 is fixedly connected to the regulating ring 221; wherein, the outer surface of the regulating tube 21 is provided with three rectangular sliding grooves, and the regulating ring 221 is fitted with the three rectangular sliding grooves in a sliding limiting manner.
[0043] Several fixed seats 311 are fixedly connected to the left side of the outer surface of the outer ring 31. The ends of the fixed seats 311 that are far apart from each other are rotatably connected to a first roller 312. Several lifting rods 32 are slidably limited to the right side of the outer surface of the outer ring 31. The ends of the lifting rods 32 that are far apart from each other are rotatably connected to a second roller 321. The ends of the lifting rods 32 that are close to each other are fixedly connected to a fixed slide rod 322. The fixed seats 311 and the lifting rods 32 correspond one-to-one, and the fixed seats 311 and the lifting rods 32 are all distributed in a ring on the outer surface of the outer ring 31.
[0044] Two fixing blocks 23 are fixedly connected to the right side of the regulating tube 21, and guide rods 231 are fixedly connected to the left side of each of the two fixing blocks 23. The two guide rods 231 slide through the moving ring 22 and extend to the outside. A fixing block 24 is fixedly connected to the right side of the regulating tube 21. The two fixing blocks 23 and the fixing block 24 are distributed in a ring at equal intervals on the right side of the regulating tube 21.
[0045] The fixed block 24 has a rotating rod 241 internally threadedly connected to it, and a rotating handle 242 is fixedly connected to the right side of the rotating rod 241. The outer surface of the rotating handle 242 is slidably limited to the moving ring 22. Two anti-detachment rings are fixedly connected to the left end of the rotating rod 241. The two anti-detachment rings are used to pull the moving ring 22 to move.
[0046] Each of the three adjusting blocks 25 is fixedly connected to a limiting rod 251 on the side away from each other. A spring 252 is sleeved on the outer surface of the limiting rod 251. One end of the spring 252 is fixedly connected to the adjusting block 25, and the other end of the spring 252 is fixedly connected to the inner wall of the adjusting tube 21. When the handle 242 is turned clockwise, the rotating rod 241 rotates, and the two anti-detachment rings at its left end drive the adjusting ring 221 to the left. The three adjusting blocks 25 lose their compression and move away from each other under the elastic force of the three springs 252. When the handle 242 is turned counterclockwise, the adjusting ring 221 moves to the right, compressing the three adjusting blocks 25 and bringing them closer together. This adjusts the distance between the three adjusting blocks 25. By compressing the wire rope with adjusting blocks 25 at different distances, the diameter of the wire rope can be controlled. This setting is highly flexible and can greatly improve production efficiency. The inner ring of the adjusting ring 221 has an arc-shaped inclined surface that matches the left side of the adjusting block 25. The three limiting rods 251 are all in sliding limiting cooperation with the adjusting tube 21.
[0047] A connecting block 33 is fixedly connected to the inner wall of the outer ring 31, and a fixing rod 331 is fixedly connected inside the connecting block 33. A hinge plate 34 is hinged to the outer surface of the fixing rod 331. The left and right sides of the hinge plate 34 are respectively provided with a first sliding groove 341 and a second sliding groove 342.
[0048] The outer ring 31 has several threaded rods 35 internally connected by threads. A knob 351 is fixedly connected to the ends of the threaded rods 35 that are far apart from each other, while a lifting frame 352 is rotatably connected to the ends of the threaded rods 35 that are close together. Rotating the knob 351 and the threaded rods 35 clockwise moves the lifting frame 352 toward the inner roller 36, causing the left end of the hinge plate 34 to move closer to the inner roller 36 and the right end to move away from the inner roller 36. At this time, the rotating roller 321 at one end of the lifting rod 32 moves away from the outer ring 31. Rotating knob 351 counterclockwise causes roller 321 to move outwards towards ring 31. This setting allows for flexible adjustment of the tension of the corresponding steel wire, ensuring sufficient tension when multiple steel wires are twisted together. This prevents breakage due to excessive force or loosening due to insufficient force. The lifting frame 352 is slidably limited to slide groove 341, and the fixed slide rod 322 is slidably limited to slide groove 342. Several connecting blocks 33 are fixedly connected to an inner roller 36 at one end that is close to each other.
[0049] A specific application of this embodiment is as follows: In use, first, the rope core 12 is passed through the base 1, the inner roller 36 and the adjusting tube 21, and then several steel wires are pulled out from the twisting machine 11. Then, the steel wires are passed between the rotating roller 312 and the fixed seat 311, and then the steel wires are passed through the side of the rotating roller 321 away from the lifting rod 32. The remaining steel wires are pulled out in the same way and passed through the adjusting tube 21 together. Finally, the right end of the steel wires and the rope core 12 is fixed to the outer ring of the take-up roller. At this time, the twisting machine 11 can be started to rotate to perform the twisting operation. The take-up roller rotates synchronously. By repeating this process, several steel wires can be twisted into strands.
[0050] To ensure sufficient tension when multiple steel wires are twisted together, preventing breakage due to excessive force or loosening due to insufficient force, the twisting machine 11 can be turned off in real time to adjust several lifting rods 32. By rotating the knob 351 and the threaded rod 35 clockwise, the lifting frame 352 will move towards the inner roller 36 because the threaded rod 35 is rotatably connected to the lifting frame 352. The hinge plate 34 is hinged to the fixed rod 331, and the fixed slide rod 322 is slidably limited by the slide groove 342. Therefore, the left end of the hinge plate 34 will move closer to the inner roller 36, and the right end will move away from the inner roller 36. At this time, the rotating roller 321 at one end of the lifting rod 32 will move away from the outer ring 31. By rotating the knob 351 counterclockwise, the rotating roller 321 will move towards the outer ring 31. This setting can flexibly adjust the tension of the corresponding steel wire.
[0051] When the diameter of the steel wire needs to be adjusted, the handle 242 can be turned clockwise, and the rotating rod 241 will follow. At this time, the two anti-detachment rings at the left end of the rotating rod 241 will drive the moving ring 22 and the adjusting ring 221 to move to the left. At this time, the three adjusting blocks 25 will move away from each other due to the loss of compression and the elastic force of the three springs 252. When the handle 242 is turned counterclockwise, the adjusting ring 221 will move to the right. During the movement, the arc-shaped inclined surface of the inner ring of the adjusting ring 221 will compress the arc-shaped inclined surface on the left side of the three adjusting blocks 25 and bring the three adjusting blocks 25 closer to each other. At this time, the three springs 252 are stretched. This setting can flexibly adjust the distance between the three adjusting blocks 25, so that the steel wire rope passing between the three adjusting blocks 25 is compressed by the three adjusting blocks 25, thereby achieving the effect of controlling the diameter of the steel wire rope.
