Description
Technical Field
[0001] This utility model relates to the technical field of strand threading machines, and more specifically, to a steel strand threading machine with an automatic guiding structure and a matching cutting mechanism. Background Technology
[0002] A prestressed steel strand threading machine, also known as a steel strand cable threading machine, steel strand wire threading machine, or steel strand tube threading machine, is a mechanically driven machine that uses rollers to clamp and transport the steel strands. It can move forward and backward, continuously or intermittently, with stepless speed adjustment. It is easy to operate, reliable, and highly efficient, significantly reducing labor intensity. Prestressed steel strand threading machines are widely used in large bridges, box girders, and structures. Because these machines need to be used in complex environments, the threaded steel strands need to be inserted into pre-fixed tubes. However, in some complex environments, it is inconvenient to directly insert the prestressed steel strands into the tubes. The wire threading machine is supported and placed, making it difficult to align the machine's outlet precisely with the pipe opening. When the gap between the machine's outlet and the pipe's inlet is too large, the processed steel strands will bend under gravity, potentially causing a positional deviation between the wire strand exiting the machine and the fixed pipe. This prevents the wire strand from being properly inserted into the pipe, requiring manual insertion by staff. This reduces the overall conveying effect of the machine on the processed steel strands and also impacts the overall conveying efficiency of the threaded steel strands.
[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: When processing steel strands, the existing stranding machine technology is prone to uneven force, which causes the steel strands to shift and slip during processing. Moreover, the existing processing technology is difficult to adapt to steel strands of different diameters, thereby reducing the utilization rate of the equipment.
[0004] Therefore, a steel strand threading machine with an automatic guiding structure and a matching cutting mechanism is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel strand threading machine with an automatic guiding structure and a matching cutting mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel strand threading machine with an automatic guiding structure and a cooperating cutting mechanism, comprising a threading device, the threading device comprising a support platform, a pulley rotatably connected to one side of the support platform, a motor device disposed on the top of the support platform, a body disposed on the top of the support platform, a cutting device disposed on the top of the support platform, a groove A being formed in the inner wall of the body, a fixed wheel passing through the inner wall of the groove A and slidably connected to the fixed wheel; The threading device is externally equipped with an adjustment device, which includes a threading disc. One end of the threading disc is equipped with a fixing disc. The end of the fixing disc away from the threading disc is rotatably connected to one side of the body. A threaded rod passes through the circumference of the threading disc and is slidably connected to the threaded rod.
[0007] Preferably, one end of the threaded rod is fixedly connected to a rotating handle, and the end of the threaded rod away from the rotating handle is fixedly connected to a connecting plate. A fixing block passes through one side of the connecting plate and is fixedly connected to the fixing block. A clamping block is fixedly connected to the side of the connecting plate away from the threaded rod. A long plate is rotatably connected to the bottom of the connecting plate, and a ring is rotatably connected to the side of the long plate away from the connecting plate. A sliding groove B is opened at the end of the fixed plate near the machine body. A connecting rod passes through the sliding groove B and is slidably connected to the connecting rod. The end of the connecting rod near the fixed plate is fixedly connected to the connecting plate, and a push plate is fixedly connected to the end of the connecting rod away from the fixed plate.
[0008] Preferably, the pulleys are four in number, arranged in pairs, and symmetrical to each other along the vertical central axis of the support platform.
[0009] Preferably, the threading device is provided with a limiting mechanism on its exterior. The limiting mechanism includes a ratchet. The ratchet is provided on the circumferential surface of the fixed plate. A rectangular box is provided on the circumferential surface of the fixed plate near the ratchet. A short plate is provided inside the rectangular box. A spring is fixedly connected to the top of the short plate. A pawl block is fixedly connected to the end of the spring away from the short plate. A limiting groove is formed on the side of the rectangular box near the ratchet. The end of the pawl block near the ratchet passes through the limiting groove and is slidably connected to the limiting groove. A sliding plate is fixedly connected to the end of the pawl block away from the limiting groove. The side of the sliding plate near the pawl block passes through the side of the rectangular box away from the limiting groove and is slidably connected to the rectangular box.
[0010] Preferably, the ratchet and the pawl block are in contact, and the pawl block is located inside the rectangular box.
[0011] Preferably, the spring is located between the short plate and the pawl block.
[0012] Preferably, there are three clamping blocks arranged in a circumferential array on the fixed disk, and there are two fixed disks arranged symmetrically to each other along the vertical central axis of the machine body.
[0013] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this steel strand threading machine with an automatic guiding structure drives the rotation of the threaded rod by rotating the handle, thereby causing the connecting rod to move horizontally, which in turn causes the long plate to move, which in turn causes the ring to rotate. This allows the three clamping blocks to extend and clamp, ensuring that the steel strand is subjected to uniform force during processing, avoiding skewing and slippage. This makes it adaptable to steel strands of different diameters, suitable for various construction scenarios, and improves equipment utilization.
[0014] Compared with existing technologies, this steel strand threading machine with an automatic guiding structure and a cutting mechanism uses a rotating fixed disc to drive a ratchet on the fixed disc to rotate. The ratchet engages with the inclined surface of the pawl block, ensuring that the fixed disc can only rotate in one direction. This effectively prevents the steel strand from retracting or loosening during processing. Furthermore, the spring always presses the pawl block against the ratchet tooth groove to maintain stable engagement, avoids accidental disengagement, and ensures a safe and reliable processing process.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1 As attached Figures 1 to 5 The diagram shows a steel strand threading machine with an automatic guiding structure and a cutting mechanism. It includes a threading device 1, a support platform 101, a pulley 102 rotatably connected to one side of the support platform 101, a motor device 103 on the top of the support platform 101, a body 104 on the top of the support platform 101, and a cutting device on the top of the support platform 101. A groove A106 is formed on the inner wall of the body 104, and a fixed wheel 107 passes through the inner wall of the groove A106 and is slidably connected to the fixed wheel 107. There are four pulleys 102, arranged in pairs, and symmetrically arranged along the vertical central axis of the support platform 101.
[0019] An adjustment device 2 is externally provided for the threading device 1. The adjustment device 2 includes a threading disc 201. A fixing disc 202 is provided at one end of the threading disc 201. The end of the fixing disc 202 away from the threading disc 201 is rotatably connected to one side of the body 104. A threaded rod 204 passes through the circumference of the threading disc 201 and is slidably connected to the threaded rod 204. A rotating handle 203 is fixedly connected to one end of the threaded rod 204. A connecting plate 205 is fixedly connected to the end of the threaded rod 204 away from the rotating handle 203. A fixing block 206 passes through one side of the connecting plate 205 and is fixedly connected to the fixing block 206. The connecting plate 205 is away from the threaded rod 204. A clamping block 207 is fixedly connected to one side of the threaded rod 204. A long plate 208 is rotatably connected to the bottom of the connecting plate 205. A ring 209 is rotatably connected to the side of the long plate 208 away from the connecting plate 205. A sliding groove B210 is opened at the end of the fixed plate 202 near the machine body 104. A connecting rod 211 passes through the sliding groove B210 and is slidably connected to the connecting rod 211. The end of the connecting rod 211 near the fixed plate 202 is fixedly connected to the connecting plate 205. A push plate 212 is fixedly connected to the end of the connecting rod 211 away from the fixed plate 202. The above design is conducive to driving the precise linear displacement of the connecting plate 205 through the threaded rod 204.
[0020] There are three clamping blocks 207 arranged in a circular array on the fixed plate 202. There are two fixed plates 202 arranged symmetrically along the vertical central axis of the machine body 104. The above design helps to ensure that the steel strand is subjected to uniform force through the clamping blocks 207, and avoids skewing or slippage.
[0021] In this application, a rotating handle 203 and a threaded rod 204 penetrate the circumference of the threaded disc 201. When the rotating handle 203 is rotated, the threaded rod 204 rotates as well. This rotation of the threaded rod 204 causes the connecting plate 205 to move horizontally, which in turn causes the clamping blocks 207 to move horizontally. Since one side of the long plate 208 is connected to the connecting plate 205 and the other side to the ring 209, the horizontal movement of the connecting plate 205 causes the long plate 208 to move, which in turn causes the fixed disc 202 to rotate. The number of clamping blocks 207 is... There are three clamping blocks 207. When the fixed plate 202 rotates, it will cause the three clamping blocks 207 to tighten. When the connecting plate 205 moves horizontally, the long plate 208 swings accordingly and causes the ring 209 to rotate slightly, ensuring that the clamping blocks 207 remain stable during tightening or loosening, avoiding jamming, and thus adapting to different devices. At the same time, when the connecting plate 205 moves horizontally, it will cause the connecting rod 211 to move in the slide groove B210, which will in turn cause the push plate 212 to move up and down, so that the push plate 212 abuts against the fixed wheel 107, causing the fixed wheel 107 to move downward, thereby clamping the material more tightly, ensuring that the material is centered, and improving work efficiency.
[0022] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details: In a preferred embodiment, a limiting mechanism 3 is provided on the outside of the threading device 1. The limiting mechanism 3 includes a ratchet 301. The ratchet 301 is provided on the circumferential surface of the fixed plate 202. A rectangular box 302 is provided on the circumferential surface of the fixed plate 202 near the ratchet 301. A short plate 303 is provided inside the rectangular box 302. A spring 304 is fixedly connected to the top of the short plate 303. A pawl block 305 is fixedly connected to the end of the spring 304 away from the short plate 303. The rectangular box 302 is located near the ratchet 301. A limiting groove 306 is provided on one side of the wheel 301. The end of the pawl block 305 near the ratchet 301 passes through the limiting groove 306 and is slidably connected to the limiting groove 306. A sliding plate 307 is fixedly connected to the end of the pawl block 305 away from the limiting groove 306. A rectangular box 302 passes through the side of the sliding plate 307 near the pawl block 305 away from the limiting groove 306 and is slidably connected to the rectangular box 302. The above design is conducive to effectively blocking dust from entering through the protective design of the rectangular box 302.
[0023] In a preferred embodiment, the ratchet 301 and the pawl block 305 are in contact, and the pawl block 305 is located inside the rectangular box 302. The above design is beneficial to prevent the steel strand from retracting or loosening during processing by the contact between the ratchet 301 and the pawl block 305.
[0024] In a preferred embodiment, the spring 304 is located between the short plate 303 and the pawl block 305. The above design is beneficial to ensure that the pawl block 305 is always pressed against the tooth groove of the ratchet 301 by the spring 304, thereby maintaining stable engagement, avoiding accidental disengagement, and ensuring safe and reliable processing.
[0025] The working process of this utility model is as follows: First, the fixed disk 202 rotates, thereby driving the ratchet 301 on the fixed disk 202 to rotate. Because the ratchet 301 is in contact with the pawl block 305, and one side of the pawl block 305 is inclined, the fixed disk 202 can only drive the ratchet 301 to move in one direction, thus forming a one-way locking mechanism. The spring 304 always presses the pawl block 305, making it engage with the tooth groove of the ratchet 301, thereby keeping the processed material in a stable state. The steel strand will not cause motion interference during processing. When it is necessary to remove the processed material, simply pull the sliding plate 307 by hand to overcome the force of the spring 304, causing the pawl block 305 to disengage from the ratchet 301, thereby removing the processed material.
[0026] The above describes the working principle of this type of steel strand threading machine with an automatic guiding structure and a matching cutting mechanism.
