Description

Technical Field

[0001] This invention relates to the field of wire winding equipment technology, specifically to a wire winding device for a steel wire mesh skeleton composite tube. Background Technology

[0002] Steel wire mesh reinforced composite pipes are widely used in municipal water supply, long-distance water transmission and distribution, industrial pipelines and other fields. As the core equipment for producing this type of pipe, the performance of the wire winding equipment directly determines the forming quality of the steel wire skeleton, which in turn affects the pressure bearing capacity and service life of the pipe.

[0003] Currently, the industry generally adopts a method of rotating multiple sets of wire feeding components driven by a wire winding disc to synchronously spirally wind multiple steel wires onto the surface of the pipe to be processed, forming a reinforcing steel wire skeleton. This is a key process in the production of steel wire mesh reinforced composite pipes. Existing conventional wire winding devices mainly consist of a wire winding disc, a drive mechanism, and multiple wire feeding shafts. The wire winding disc can rotate around the axis of the pipe to be processed, and the drive mechanism drives its rotation. Each wire feeding shaft carries a steel wire cylinder. When the pipe passes through the wire winding disc at a uniform speed, the drive mechanism controls the wire winding disc to rotate at a uniform speed, so that multiple steel wires are evenly spirally wound on the surface of the pipe. During wire feeding, the tension generated by the continuous winding of the steel wires around the pipe drives all the steel wire cylinders to rotate and feed the material. To prevent the steel wires from loosening, the wire feeding shafts that carry the steel wire cylinders are generally designed with a certain rotational resistance.

[0004] It is important to note that the winding disc needs to rotate continuously and at high speed around the tube during operation. The special nature of its main rotation makes it difficult to install electronic sensors and power actuators with power supply lines and signal lines on the disc. This is because the wires of various electronic components will become entangled and pulled as the disc rotates, causing equipment failure. Therefore, the tension adjustment of existing low-cost winding devices can only adopt mechanical structures as much as possible to avoid wire collision.

[0005] However, the existing mechanical adjustment method has obvious drawbacks: it is difficult to achieve precise synchronization of the frictional force of all wire feeding shafts, which leads to some wire feeding shafts rotating excessively and the wires becoming loose when the wires are pulled, while others rotate poorly and the wires are subjected to uneven force. Ultimately, the wire skeleton is not formed evenly, which affects the pressure-bearing stability of the pipe and reduces the yield of finished pipes. Summary of the Invention

[0006] To address this issue, this invention provides a wire mesh skeleton composite tube winding device to solve the problem of accurately synchronizing the rotational friction of all pay-off shafts in the prior art.

[0007] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0008] A wire mesh reinforced composite tube winding device, comprising:

[0009] The wire winding disc allows the tube to be processed to pass through its central hole, and the wire winding disc can rotate around the central axis of the tube. The wire winding disc has an annular hydraulic cavity inside for filling with hydraulic oil.

[0010] A drive mechanism, installed along the tube transport path, is used to connect to and drive the winding disc to rotate;

[0013] A damping adjustment unit is disposed between the pay-off shaft and the winding disc. The damping adjustment unit is connected to the annular hydraulic cavity. An increase in the hydraulic pressure in the annular hydraulic cavity can cause the damping adjustment unit to squeeze the pay-off shaft. The force by which the damping adjustment unit squeezes the pay-off shaft corresponds to the friction force that the pay-off shaft needs to overcome when it rotates.

[0014] A hydraulic control unit is disposed on the winding disc and communicates with the annular hydraulic cavity. The hydraulic control unit can adjust the hydraulic pressure in the annular hydraulic cavity to synchronously adjust the rotational friction of all pay-off shafts.

[0017] The first piston is always slidably connected within the first sliding cavity, and the hydraulic changes within the annular hydraulic cavity enable the first piston to slide bidirectionally within the first sliding cavity.

[0018] A damping plate is fixed to the end face of the first piston near the pay-off shaft. When the first piston slides toward the pay-off shaft, the damping plate is used to squeeze the pay-off shaft to increase the frictional force that the pay-off shaft needs to overcome to rotate.

[0019] In a preferred embodiment of the present invention, the pay-off shaft includes:

[0020] A fixed shaft plate is located on the outer periphery of the damping adjustment unit and is fixedly installed on the winding disc. A limiting groove is provided on the inner side of the fixed shaft plate along the inner circumferential surface.

[0021] The shaft body is movably sleeved on the outside of the corresponding damping adjustment unit, and the end of the shaft body extends to the inside of the fixed shaft plate;

[0022] The limiting ring is always movably fitted inside the limiting groove and fixedly fitted outside the shaft.

[0023] As a preferred embodiment of the present invention, a second sliding cavity is provided at one end of the shaft and a tube groove is provided at the other end of the shaft. The second sliding cavity and the tube groove are both located on the central axis of the shaft. A third sliding cavity extending along the length direction of the shaft is provided on the inner wall of the second sliding cavity, and a plurality of equally spaced slots are provided on the inner wall of the third sliding cavity.

[0024] As a preferred embodiment of the present invention, a sliding plug is slidably connected in the second sliding cavity, and a sliding column located in the third sliding cavity is provided on the outside of the sliding plug. When the sliding plug slides in the second sliding cavity, it slides together with the sliding column in the third sliding cavity. Furthermore, the sliding plug can be rotated clockwise to allow the sliding column to be embedded in the nearest slot to fix the position of the sliding plug.

[0025] As a preferred embodiment of the present invention, the second sliding cavity is provided with a spring for elastically supporting the end of the sliding plug, and a friction plate for contacting the damping plate is fixed on the inner wall of the tube groove.

[0026] As a preferred embodiment of the present invention, the outer side of the shaft is provided with two symmetrically distributed card slots, and the second sliding cavity is provided with two fourth sliding cavities respectively distributed toward the two card slots;

[0027] A second piston slides in both of the two fourth sliding cavities, and a top-closing piece is provided in both of the two card slots. Each second piston is connected to the corresponding top-closing piece through a support rod.

[0028] When the top fitting piece is located in the card slot, the outer curvature of the top fitting piece is consistent with the outer curvature of the shaft body, and the outer surface of the top fitting piece is provided with anti-slip texture.

[0029] As a preferred embodiment of the present invention, the hydraulic control unit includes:

[0030] A tubular hydraulic container is fixedly installed on the other end face of the wire winding disc, and the interior of the tubular hydraulic container is in communication with the annular hydraulic cavity;

[0031] The third piston, which is slidably connected inside the tubular hydraulic container, increases the hydraulic pressure in the annular hydraulic cavity when it slides toward the wire-winding disc.

[0032] A lead screw is threadedly connected to the tubular hydraulic container, one end of the lead screw is rotatably connected to the third piston, and the other end of the lead screw is provided with a handle;

[0033] A mechanical pressure gauge is installed on the tubular hydraulic container and used to detect the hydraulic pressure value inside the tubular hydraulic container in real time.

[0034] The embodiments of the present invention have the following advantages:

[0035] This invention achieves precise and synchronous adjustment of the rotational friction of all wire-laying shafts by setting an annular hydraulic cavity inside the wire-winding disc and adjusting the hydraulic pressure inside the cavity with the help of a hydraulic control unit. This effectively improves the core problems of existing mechanical adjustment methods, such as loose winding of multiple steel wires, uneven force distribution, and irregular forming, and enhances the uniformity of steel wire skeleton forming and the pressure-bearing stability of the pipe.

At the same time, only the winding disc needs to be replaced to complete the upgrade and iteration of old equipment, resulting in low modification costs. Attached Figure Description

[0055] Example 1

[0056] like Figures 1 to 7As shown, a wire mesh reinforced composite tube winding device is disclosed. This invention aims to solve the problem in existing winding devices where the frictional force of the pay-off shaft rotation is difficult to synchronize when multiple wires are wound, resulting in loose and irregular wires. It is also suitable for working conditions where electronic components cannot be installed due to the continuous rotation of the winding disc. The main solution is to set up an annular hydraulic cavity inside the winding disc, and coordinate with the hydraulic control unit to synchronously adjust the frictional force of all damping adjustment units. A fully mechanical structure is used to achieve precise tension control.

[0057] include:

[0058] The wire winding disc 1 allows the tube to be processed to pass through the central hole of the wire winding disc 1, and the wire winding disc 1 can rotate around the central axis of the tube to be processed. The inside of the wire winding disc 1 is provided with an annular hydraulic cavity 11 for filling with hydraulic oil.

[0059] Drive mechanism 2, installed along the tube transport path, is used to connect to and drive the winding disc 1 to rotate;

[0060] Multiple wire feeding assemblies 3 are located on one end face of the winding disc 1 and are evenly distributed around its central axis. Each wire feeding assembly 3 includes:

[0061] The wire feeding shaft 31 is rotatably connected to the winding disc 1 and is used to carry the wire cylinder;

[0062] The damping adjustment unit 32 is disposed between the pay-off shaft 31 and the winding disc 1. The damping adjustment unit 32 is connected to the annular hydraulic cavity 11. The increase in hydraulic pressure in the annular hydraulic cavity 11 can cause the damping adjustment unit 32 to squeeze the pay-off shaft 31. The force of the damping adjustment unit 32 squeezing the pay-off shaft 31 corresponds to the friction force that the pay-off shaft 31 needs to overcome when it rotates.

[0063] The hydraulic control unit 4 is mounted on the winding disc 1 and communicates with the annular hydraulic cavity 11. The hydraulic control unit 4 can adjust the hydraulic pressure in the annular hydraulic cavity 11 to synchronously adjust the rotational friction of all the wire feeding shafts 31.

[0064] This invention replaces the existing independent damping adjustment method of a single wire feeding shaft with a fully mechanical hydraulic synchronous adjustment structure. The winding disc 1 serves as the core mounting carrier, and the built-in annular hydraulic cavity 11 realizes the synchronous transmission of hydraulic pressure. The drive mechanism 2 provides rotational power to the winding disc 1. Multiple wire feeding components 3 are distributed around it to realize the synchronous winding of multiple steel wires. The hydraulic control unit 4 precisely adjusts the hydraulic pressure, thereby synchronously controlling the rotational friction of all wire feeding shafts 31, fundamentally improving the problems of loose wire winding and uneven force distribution.

[0065] Specifically, the winding disc 1 serves as the core mounting base of the entire device. Its central hole allows the tube to be processed to pass through smoothly. To accommodate tubes of different diameters and prevent damage caused by friction between the tube and the inner wall of the central hole, and to ensure that the winding disc 1 rotates coaxially with the tube, both the upper and lower level devices of the winding device are in contact with the tube for fixation. This ensures that the tube remains on its central axis as it passes through the winding disc 1, preventing tube displacement. The annular hydraulic cavity 11 inside the winding disc 1 adopts a closed annular structure, which allows the hydraulic oil to be evenly distributed within the cavity, ensuring that the hydraulic pressure is synchronously transmitted to each damping adjustment unit 32. This built-in design saves installation space and prevents the hydraulic lines from being exposed and entangled or worn by the wire. It also fits the continuous rotation of the winding disc 1, eliminating the need for complex additional pipe connections and effectively avoiding the risk of wire entanglement.

[0066] Since the winding disc 1 needs to rotate continuously to achieve wire winding, the drive mechanism 2, as the core conventional component providing power, must adapt its installation and transmission method to the working requirements of the winding disc 1. Specifically, the drive mechanism 2 adopts an existing conventional motor reduction transmission structure, including a drive motor, a reduction gearbox, a drive gear, and a driven gear. After the drive motor starts, the reduction gearbox reduces the speed and increases the torque, driving the drive gear to rotate, which in turn drives the driven gear and the winding disc 1 to rotate synchronously. This gear transmission method has high transmission efficiency and large torque, ensuring stable rotation speed of the winding disc 1 and meeting the speed requirements for synchronous winding of multiple wires. At the same time, the gear transmission structure is stable and easy to maintain, belonging to the conventional drive method in wire winding equipment. It does not require additional complex power structure design, which reduces equipment costs and adapts to the installation conditions of existing production lines. Considering that the rotation speed of the winding disc 1 needs to be adjusted according to the tube conveying speed during the winding process, the drive motor adopts an adjustable speed motor. The operator can adjust the motor speed to coordinate with the tube conveying speed to precisely control the spiral pitch of the wire winding, further improving the forming quality of the wire skeleton.

[0067] The damping adjustment unit 32 includes:

[0068] The guide tube 321 is fixedly connected to the winding disc 1. A first sliding cavity 3211 is provided on the inner side of the guide tube 321, and the first sliding cavity 3211 is connected to the annular hydraulic cavity 11.

[0069] The first piston 322 is always slidably connected in the first sliding cavity 3211. The hydraulic pressure changes in the annular hydraulic cavity 11 enable the first piston 322 to slide bidirectionally in the first sliding cavity 3211.

[0070] The damping plate 323 is fixed on the end face of the first piston 322 near the pay-off shaft 31. When the first piston 322 slides toward the pay-off shaft 31, the damping plate 323 is used to squeeze the pay-off shaft 31 to increase the friction force that the pay-off shaft 31 needs to overcome to rotate.

[0071] Specifically, in order to convert the hydraulic pressure in the annular hydraulic cavity 11 into a squeezing force on the pay-off shaft 31 and thereby adjust its rotational friction, a damping adjustment unit 32 is provided. The guide tube 321 is fixed on the winding disc 1, which plays a fixing and guiding role. The first sliding cavity 3211 inside is connected to the annular hydraulic cavity 11 to ensure that the hydraulic oil can smoothly enter the first sliding cavity 3211 to drive the first piston 322 to slide. The first piston 322 and the first sliding cavity 3211 adopt a sealed sliding fit to avoid hydraulic oil leakage affecting the stability of pressure transmission. The damping plate 323 is fixed at the end of the first piston 322 and is made of wear-resistant material. It can increase the friction between the first piston 322 and the pay-off shaft 31, while avoiding direct squeezing that causes wear on the pay-off shaft 31. When the pressure in the annular hydraulic cavity 11 increases, the first piston 322 drives the damping plate 323 to move towards the pay-off shaft 31 and squeeze, so that the friction force that the pay-off shaft 31 needs to overcome to rotate increases. Conversely, when the pressure decreases, the friction force decreases, thus achieving a smooth adjustment of the friction force.

[0072] The wire feeding shaft 31 includes:

[0073] The fixed shaft plate 311 is located on the outer periphery of the corresponding damping adjustment unit 32 and is fixedly installed on the winding disc 1. The inner side of the fixed shaft plate 311 is provided with a limiting groove 3111 distributed along the inner circumferential surface.

[0074] The shaft 312 is movably sleeved on the outside of the corresponding damping adjustment unit 32, and the end of the shaft 312 extends to the inside of the fixed shaft piece 311.

[0075] The limiting ring 313 is always movably sleeved inside the limiting groove 3111 and fixedly sleeved outside the shaft 312.

[0076] Specifically, the wire feeding shaft 31 is used to carry the wire cylinder and achieve stable rotation. In order to ensure the stability of the wire feeding shaft 31 rotating on the winding disc 1 and to avoid deviation or shaking during rotation, a fixed shaft plate 311 and a limiting ring 313 are provided. The fixed shaft plate 311 is fixed on the winding disc 1, and the limiting groove 3111 on its inner side is adapted to the limiting ring 313. The limiting ring 313 is fixed on the outside of the shaft body 312 and can rotate freely in the limiting groove 3111, while limiting the axial displacement of the shaft body 312, ensuring that the shaft body 312 always rotates around its own axis. The shaft body 312 is movably sleeved on the outside of the damping adjustment unit 32, which does not affect the normal operation of the damping adjustment unit 32, and can obtain uniform friction under the compression of the damping plate 323, ensuring the smoothness during rotation, and thus ensuring the stability of the tension during wire feeding.

[0077] The shaft 312 has a second sliding cavity 3121 at one end and a tube groove 3122 at the other end. Both the second sliding cavity 3121 and the tube groove 3122 are located on the central axis of the shaft 312. A third sliding cavity 3123 extending along the length of the shaft 312 is formed on the inner wall of the second sliding cavity 3121. A plurality of equally spaced slots 3124 are formed on the inner wall of the third sliding cavity 3123.

[0078] Specifically, the shaft 312 is the core component of the wire feeding shaft 31. The groove 3122 at one end is used to contact the damping plate 323 of the damping adjustment unit 32 to ensure that the extrusion force of the damping plate 323 can be evenly applied to the shaft 312. The second sliding cavity 3121 at the other end is used to install components such as the sliding plug 314 to provide adjustment space for clamping the wire spool. The third sliding cavity 3123 is opened along the length of the shaft 312 to limit the sliding direction of the sliding column 3141 and prevent the sliding plug 314 from deviating when rotating. Multiple equally spaced slots 3124 are used to fix the position of the sliding plug 314.

[0079] The second sliding cavity 3121 is slidably connected to a slide plug 314. The outer side of the slide plug 314 is provided with a slide post 3141 located in the third sliding cavity 3123. When the slide plug 314 slides in the second sliding cavity 3121, it slides together with the slide post 3141 in the third sliding cavity 3123. The slide plug 314 can be rotated clockwise so that the slide post 3141 can be inserted into the nearest slot 3124 to fix the position of the slide plug 314.

[0080] Specifically, to achieve the adjustability and fixation of the slide plug 314, the slide plug 314 is slidably connected in the second slide cavity 3121, and its outer slide post 3141 is embedded in the third slide cavity 3123, so that the slide plug 314 can only slide along the axis of the shaft 312 and cannot rotate freely. When it is necessary to fix the position of the slide plug 314, the slide plug 314 is rotated clockwise, so that the slide post 3141 is embedded in the corresponding slot 3124. The slide plug 314 is fixed by the snapping action of the slot 3124 and the slide post 3141. This design can achieve precise positioning of the slide plug 314 and facilitate quick adjustment by the operator. It solves the problem that the position of the existing wire rod cylinder cannot be flexibly adjusted after clamping. At the same time, the structure is simple, no additional fixing parts are required, and it meets the requirements of fully mechanical design.

[0081] It is worth noting that the sliding stroke of the slide rod 3141 in the third slide cavity 3123 is the same as the sliding stroke of the slide plug 314 in the second slide cavity 3121. Throughout the sliding process of the slide plug 314, the slide plug 314 always covers the third slide cavity 3123. Therefore, the space in the second slide cavity 3121 can be filled with hydraulic oil. When the slide plug 314 slides into the second slide cavity 3121, the hydraulic oil pressure will increase.

[0082] The second sliding cavity 3121 is provided with a spring 315 for elastically supporting the end of the sliding plug 314, and a friction plate 316 for contacting the damping plate 323 is fixed on the inner wall of the tube groove 3122.

[0083] Specifically, to enable the slide plug 314 to automatically reset and facilitate subsequent adjustment and disassembly of the wire rod, a spring 315 is installed in the second sliding cavity 3121. The spring 315 elastically supports the end of the slide plug 314. When the slide pin 3141 is dislodged from the slot 3124, the spring 315 can push the slide plug 314 to automatically reset, reducing manual operation steps and improving work efficiency. At the same time, the elasticity of the spring 315 can also buffer the impact force when the slide plug 314 slides, preventing damage to the components. The friction plate 316 on the inner wall of the tube groove 3122 is made of a high friction coefficient material. Its function is to increase the friction force between the damping plate 323 and the shaft 312, making the friction force adjustment more precise, avoiding direct contact between the damping plate 323 and the shaft 312 and causing wear, extending the service life of the shaft 312 and the damping plate 323, and ensuring the stability of the friction force adjustment, further improving the regularity of the wire winding.

[0084] Among them, the outer side of the shaft 312 is provided with two symmetrically distributed card slots 3125, and the second sliding cavity 3121 is provided with two fourth sliding cavities 3126 respectively distributed towards the two card slots 3125;

[0085] A second piston 317 slides in each of the two fourth sliding cavities 3126, and a top plate 318 is provided in each of the two card slots 3125. Each second piston 317 is connected to the corresponding top plate 318 through a support rod 319.

[0086] When the top fitting piece 318 is located in the card slot 3125, the outer curvature of the top fitting piece 318 is consistent with the outer curvature of the shaft 312, and the outer surface of the top fitting piece 318 is provided with texture for anti-slip.

[0087] Specifically, to achieve a stable clamping of the wire spool on the shaft 312 and prevent slippage of the wire spool during winding, which could lead to unstable wire feeding, a card slot 3125 and a top clamping plate 318 are provided on the outside of the shaft 312. The fourth sliding cavity 3126 is used to install the second piston 317 and the support rod 319. When the sliding plug 314 slides in the second sliding cavity 3121, the increased pressure of the hydraulic oil pushes the second piston 317 to slide in the fourth sliding cavity 3126, which in turn drives the top clamping plate 318 to the card slot via the support rod 319. As the groove 3125 moves outward, the top clamping plate 318 contacts and presses against the inner wall of the wire barrel, thus fixing the barrel. The outer arc of the top clamping plate 318 is consistent with that of the shaft 312, which can fit tightly against the inner wall of the barrel, increasing the contact area. The anti-slip texture further increases the friction, effectively preventing the barrel from slipping. This clamping method is suitable for wire barrels with different inner diameters and has strong versatility. At the same time, clamping and disassembly are achieved by adjusting the sliding plug 314, which is convenient to operate and does not require additional clamping tools, which is in line with the actual production conditions of the wire winding device.

[0088] The hydraulic control unit 4 includes:

[0089] A tubular hydraulic container 41 is fixedly installed on the other end face of the wire winding disc 1, and the interior of the tubular hydraulic container 41 is in communication with the annular hydraulic cavity 11.

[0090] The third piston 42 is slidably connected inside the tubular hydraulic container 41. When the third piston 42 slides toward the wire-winding disc 1, it increases the hydraulic pressure in the annular hydraulic cavity 11.

[0091] The lead screw 43 is threadedly connected to the tubular hydraulic container 41. One end of the lead screw 43 is rotatably connected to the third piston 42, and the other end of the lead screw 43 is provided with a handle 431.

[0092] A mechanical pressure gauge 44 is installed on the tubular hydraulic container 41 and is used to detect the hydraulic pressure value inside the tubular hydraulic container 41 in real time.

[0093] Specifically, the hydraulic control unit 4 is used to adjust the hydraulic pressure in the annular hydraulic cavity 11, thereby synchronously controlling the rotational friction of all the wire feeding shafts 31. Considering the special characteristic of the continuous rotation of the winding disc 1, it is not possible to install electronic pressure adjustment and detection components with power supply lines and signal lines. Therefore, the entire hydraulic control unit 4 adopts a fully mechanical design. The tubular hydraulic container 41 is fixed to the other end face of the winding disc 1 and communicates with the annular hydraulic cavity 11. It is used to store hydraulic oil and transmit pressure. The third piston 42 is sealed and slides with the tubular hydraulic container 41 to ensure the stability of pressure transmission. The lead screw 43 is threadedly connected to the tubular hydraulic container 41. The operator rotates the handle 431. The screw 43 rotates, which in turn pushes the third piston 42 to slide towards the winding disc 1, squeezing the hydraulic oil in the tubular hydraulic container 41 and increasing the pressure in the annular hydraulic chamber 11. Conversely, rotating the handle 431 in the opposite direction reduces the pressure. The mechanical pressure gauge 44 is used to detect the hydraulic pressure value in real time, allowing operators to accurately adjust the pressure according to production needs, avoiding wire breakage due to excessive pressure or wire loosening due to insufficient pressure. This fully mechanical design requires no electronic components, effectively avoiding entanglement and pulling failures caused by the wire rotating with the winding disc 1, ensuring the stability of equipment operation. At the same time, it has a simple structure, low cost, and is easy to adapt to the upgrading and transformation of existing production lines.

[0094] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
