Abstract

This invention discloses a winding device for steel wire mesh reinforced plastic composite pipe, belonging to the field of composite pipe production technology. It includes: a mounting frame with a central hole for the pipe to pass through; a drive mechanism mounted on the mounting frame; a front wire feeding mechanism and a rear wire feeding mechanism, each including a turntable and at least one set of wire storage trays mounted on the turntable. The drive mechanism is simultaneously linked to both turntables and can drive both turntables to rotate. During this time, each of the wire storage trays performs a wire feeding action, and the steel wire is guided to the surface of the pipe. As the pipe continues to move forward, the synchronous wire feeding of the wire storage trays and the configuration of the left and right winding devices form a steel wire mesh composite reinforcement layer. By setting the front and rear wire feeding mechanisms on the front and rear sides of the mounting frame respectively, the weight of the winding device is evenly distributed on both sides of the mounting frame, forming a force balance state and increasing the load-bearing capacity of the turntable, avoiding the requirement for extremely high overall structural strength due to unilateral force.

Description

Technical Field

[0001] This invention belongs to the field of composite pipe production technology, specifically relating to a winding device for steel wire mesh reinforced plastic composite pipe. Background Technology

[0002] To improve the mechanical properties of pipelines, a winding machine is typically used to wind reinforcing materials such as steel wire, steel strip, and fiber tape onto plastic pipes to form composite pipes. The winding machine mainly consists of a fixed frame and a turntable mechanism (rotating support) pivotally connected to it. As the plastic pipe is conveyed forward along the rotation axis of the turntable mechanism, the turntable mechanism drives the reinforcing material on it to rotate and release the reinforcing material from the reel, thereby winding the reinforcing material onto the plastic pipe to form a composite pipe.

[0003] The winding device includes at least a drive mechanism and a turntable mechanism. The drive mechanism drives the turntable mechanism to rotate. The turntable mechanism winds the reinforcing material wound on it onto the forward-conveyed pipe. Depending on the winding method of the reinforcing material, for example, forming a cross-shaped reinforcing surface, one or more pairs of left and right rotating disc mechanisms need to be provided.

[0004] However, in current winding devices, the turntable mechanism is located on the same side of the drive mechanism. This results in a long and large device with a concentrated weight on the cantilever of the drive mechanism, which places extremely high strength requirements on the drive mechanism. In addition, winding the wire mesh reinforcement layer on large-diameter pipes requires more wires, which increases the diameter of the turntable. Furthermore, a foundation pit needs to be dug in the ground to install the bulky winding device.

[0005] For example, an invention patent with publication number CN210283308U in the prior art discloses a winding machine, including: a fixed frame (1); a slewing bearing (2), which includes an inner ring (21), an outer ring (22) and a rolling element (23), the inner ring being fixed to one side of the fixed frame (1), the outer ring being connected to a drive device and coaxially mounted on the outer periphery of the inner ring through the rolling element (23); a rotating bracket (3), on which a pulley (4) is mounted and fixedly connected at one end to the outer ring (22), so that during the process of the rotating bracket (3) being driven by the drive device to rotate together with the outer ring (22), the reinforcing strip (5) on the pulley (4) is wound onto a core tube (6) that passes through the rotating bracket (3) and extends along the rotation axis of the slewing bearing (2).

[0006] The turntable mechanisms of the winding machines provided in the above-mentioned comparative documents are all installed on the same side of the fixed frame (1), which causes the overall weight to be concentrated on the drive mechanism installed inside the fixed frame (1). This not only requires the drive mechanism to have extremely high strength, but also requires the digging of a base pit on the ground to install the winding device when adding layers to large-diameter pipes, resulting in a high overall cost. Summary of the Invention

[0007] This invention addresses the aforementioned problems in the prior art by proposing a winding device for steel wire mesh reinforced plastic composite pipes that evenly distributes weight on both sides of the mounting frame, reduces volume, and lowers costs.

[0008] This invention can be achieved through the following technical solutions:

[0009] A winding device for steel wire mesh reinforced plastic composite pipe, comprising:

[0010] Mounting bracket, which has a central hole for pipes to pass through;

[0011] The drive mechanism is mounted on the mounting bracket;

[0012] The front wire feeding mechanism and the rear wire feeding mechanism each include a turntable and at least one set of wire storage trays mounted on the turntable. The driving mechanism is simultaneously linked to both turntables and drives the two turntables to rotate. At the same time, each of the wire storage trays on one side of the two turntables performs a wire feeding action. The steel wire is guided to the surface of the pipe. As the pipe continues to move forward and the wire storage trays rotate synchronously to feed the wire, and with the configuration of left and right spiral winding devices, a steel wire mesh composite reinforcement layer is formed.

[0013] The front wire feeding mechanism and the rear wire feeding mechanism are respectively arranged on the front and rear sides of the mounting frame, so that the weight of the winding device can be evenly distributed on both sides of the mounting frame.

[0014] As a further improvement of the present invention, the mounting frame includes two mounting plates, and the drive mechanism is mounted on the mounting plates and is linked to the front wire feeding mechanism and the rear wire feeding mechanism.

[0015] As a further improvement of the present invention, the driving mechanism includes:

[0016] A drive motor, which is mounted on the mounting bracket;

[0017] A gear bearing structure that is connected to both the turntable and the mounting plate;

[0018] The transition shaft is connected to the drive motor via a sprocket. Both ends of the transition shaft pass through the two mounting plates and are equipped with drive gears. The two drive gears mesh with the external teeth of the gear bearing structure of the front wire feeding mechanism and the rear wire feeding mechanism, respectively.

[0019] The drive motor drives the transition shaft and the drive gear to rotate. The drive gear drives the turntable to rotate through the gear bearing structure. At this time, the wire storage trays set on one side of the two turntables rotate and release wire synchronously. As the tube continues to move forward and the left and right winding devices are configured, the two adjacent layers of steel wire are intersected and pressed tightly onto the tube.

[0020] As a further improvement of the present invention, the gear bearing structure includes an inner ring and an outer ring, the inner ring of which is mounted on the mounting plate and the outer ring of which is mounted on the turntable.

[0021] As a further improvement of the present invention, the tooth surface of the outer ring of the gear bearing meshes with the drive gear. As the drive gear rotates, it drives the outer ring of the gear bearing to rotate, thereby realizing the rotation of the turntable and the rotation and wire feeding action of the wire storage disc.

[0022] As a further improvement of the present invention, a set of wire storage trays is composed of multiple individual wire storage trays. Multiple sets of wire storage trays are evenly distributed along the central circumference on one side of the turntable. The multiple sets of wire storage trays can be arranged in circles, and the centers of the inner and outer circles of wire storage trays are staggered. At the same time, the front wire feeding mechanism and the rear wire feeding mechanism are respectively provided with transition wire rings. The steel wires on each wire storage tray are led outward through the transition wire rings.

[0023] As a further improvement of the present invention, the front end of the wire feeding mechanism is provided with at least one wire splitting ring and a wire guide ring, and the steel wires output from each of the wire storage discs are sequentially drawn to the surface of the pipe after passing through the wire splitting ring and the wire guide ring.

[0024] As a further improvement of the present invention, the inner ring of the turntable is also equipped with a wire feeding tube, wherein each of the wire storage discs on the rear wire feeding mechanism is led out through its respective transition wire ring, passes through the wire feeding tube and is pulled to the wire separating ring.

[0025] As a further improvement of the present invention, the front end of the guide ring is further provided with a wire locking mechanism, the wire locking mechanism comprising:

[0026] A locking ring seat, the bottom of which is provided with a mounting base for adjusting the front and rear positions of the locking ring seat;

[0027] A locking ring is installed on the locking ring seat. The pipe passes through the locking ring, and the steel wires led out from the guide ring are pulled into the space formed by the outer diameter of the pipe and the inner hole of the locking ring, so that the steel wires are pressed tightly against the outer wall of the pipe and evenly distributed.

[0028] As a further improvement of the present invention, the steel wires, which are pressed and evenly distributed by the locking ring, are spirally wound on the outer wall of the pipe, and a steel wire mesh composite reinforcement layer is formed covering the surface of the pipe by the configuration of left and right spiral winding devices.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The front wire feeding mechanism and the rear wire feeding mechanism are respectively set on the front and rear sides of the mounting frame, so that the weight of the winding device can be evenly distributed on the front and rear sides of the mounting frame. Thus, the entire device forms a front-to-back force balance state, avoiding the mounting frame and drive mechanism from being subjected to one-sided force, which requires the overall structure to have extremely high strength. Therefore, the load capacity of the turntable can be increased, and the number of wire storage trays can be increased. The double or multi-ring wire storage tray layout on the turntable shortens the length and volume of the entire winding device. For wire mesh winding of large-diameter pipes, there is no need to dig a foundation pit in the ground to install the winding device, which greatly reduces the production cost of enterprises.

[0031] 2. Through the cooperation of the drive mechanism and the gear bearing structure, the front wire feeding mechanism and the rear wire feeding mechanism can feed wire synchronously. At the same time, through the transmission structure formed by the transition shaft, drive gear, and double gear structure, the overall layout is compact, which improves the space utilization of the entire winding device and further reduces its volume.

[0032] 3. The steel wires drawn from each wire storage disc are uniformly dispersed by the wire distribution ring, then guided by the wire guide ring, and finally wound on the surface of the pipe in a specific direction and at a specific interval to form a reinforcing layer with a specific shape layout.

[0033] 4. The wire feeding tube helps to gather and guide the multiple strands of steel wire drawn from the rear wire feeding mechanism, so that they can be pulled to the wire splitting ring along a specific path, ensuring that there is no interference with the steel wire drawn from the front wire feeding mechanism, thereby improving the reliability and stability of the wire feeding process.

[0034] 5. The steel wires, which are tightened and evenly distributed by the locking rings, are spirally wound on the outer wall of the pipe. The configuration of left and right spiral winding devices forms a steel wire mesh reinforcement layer covering the surface of the pipe. By changing the locking rings and adjusting the front and rear positions of the locking ring seats, the device can be adapted to winding pipes with different outer diameters, thereby improving the versatility and adaptability of the winding device.

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical methods of the present invention. However, the present invention is not limited to these embodiments.

[0042] like Figure 1-3 As shown, the present invention provides a winding device for steel wire mesh reinforced plastic composite pipe, comprising:

[0043] Mounting bracket 100 has a central hole for pipes to pass through;

[0044] The drive mechanism 200 is mounted on the mounting bracket 100;

[0045] The front wire feeding mechanism 300 and the rear wire feeding mechanism 310 each include a turntable 320 and at least one set of wire storage trays 330 mounted on the turntable 320. The drive mechanism 200 is simultaneously linked to the two turntables 320. The drive mechanism 200 drives the two turntables 320 to rotate, and at the same time, each of the wire storage trays 330 on one side of the two turntables 320 performs a wire feeding action. The steel wire is guided to the surface of the pipe. With the continuous forward movement of the pipe and the synchronous rotation of the wire storage trays 330 to feed the wire, as well as the configuration of the left and right spiral winding devices, a steel wire mesh composite reinforcement layer is formed.

[0046] The front wire feeding mechanism 300 and the rear wire feeding mechanism 310 are respectively set on the front and rear sides of the mounting frame 100, so that the weight of the winding device can be evenly distributed on the front and rear sides of the mounting frame 100. Thus, the entire device forms a front-to-back force balance state, avoiding the requirement of extremely high strength of the overall structure of the mounting frame 100 and the drive mechanism 200 due to unilateral force. Therefore, the load capacity of the turntable 320 can be increased, and the number of wire storage trays 330 can be increased. The double or multi-turn wire storage trays 330 on the turntable 320 shorten the length and volume of the entire winding device. For wire mesh winding of large-diameter pipes, there is no need to dig a foundation pit in the ground to install the winding device, which greatly reduces the production cost of enterprises.

[0047] Preferably, the mounting frame 100 includes two mounting plates 110, and the drive mechanism 200 is mounted on the two mounting plates 110 and is linked to the front wire feeding mechanism 300 and the rear wire feeding mechanism 310.

[0048] Preferably, the drive mechanism 200 includes:

[0049] The drive motor 210 is mounted on the mounting bracket 100;

[0050] The gear bearing structure 220 is connected to both the turntable 320 and the mounting plate 110.

[0051] The transition shaft 230 is connected to the drive motor 210 via a sprocket 240. The two ends of the transition shaft 230 pass through two mounting plates 110 and are equipped with drive gears 250. The two drive gears 250 mesh with the external teeth of the gear bearing structure 220 of the front wire feeding mechanism 300 and the rear wire feeding mechanism 310, respectively.

[0052] The drive motor 210 drives the transition shaft 230 and drive gear 250 to rotate. The drive gear 250 drives the turntable 320 to rotate through the gear bearing structure 220. At this time, the wire storage disc 330 set on one side of the two turntables 320 simultaneously performs the wire feeding action. As the tube continues to move forward and the left and right spiral winding devices are configured, the two adjacent layers of steel wire can be intersected and tightly wound on the tube.

[0053] Preferably, the gear bearing structure 220 includes an inner ring gear bearing 221 and an outer ring gear bearing 222. The inner ring gear bearing 221 is mounted on the mounting plate 110, and the outer ring gear bearing 222 is mounted on the turntable 320. Specifically, the tooth surface of the outer ring gear bearing 222 meshes with the drive gear 250. As the drive motor 210 drives the transition shaft 230 to rotate, the drive gears 250 at both ends of the transition shaft 230 can drive the outer ring gear bearing 222 to rotate. At this time, the turntable 320 rotates accordingly and realizes the rotation and wire feeding action of the wire storage tray 330. The inner ring gear bearing 221 is connected to the mounting bracket 100 and is always in a fixed state.

[0054] Through the cooperation of the drive mechanism 200 and the gear bearing structure 220, the front wire feeding mechanism 300 and the rear wire feeding mechanism 310 can feed wire synchronously, and as the pipe moves forward, the steel wire is spirally wound on the outer wall of the pipe.

[0055] Preferably, a set of wire storage trays 330 consists of multiple individual wire storage trays 330. At the same time, the front wire feeding mechanism 300 and the rear wire feeding mechanism 310 are respectively provided with transition wire rings 340. The steel wires on each wire storage tray 330 are led outward through an individual transition wire ring 340, so that the steel wires led out from each wire storage tray 330 are led out independently and will not interfere with each other.

[0056] Preferably, the front end of the wire feeding mechanism 300 is further provided with at least one wire splitting ring 350 and a wire guide ring 360. The steel wires output from the two sets of wire storage discs 330 are sequentially pulled to the surface of the pipe after passing through the wire splitting ring 350 and the wire guide ring 360. The steel wires led out from each wire storage disc 330 are uniformly dispersed by the wire splitting ring 350, then pulled and guided by the wire guide ring 360, and finally wound on the surface of the pipe in a specific direction and at a specific interval to form a reinforcing layer with a specific shape.

[0057] Preferably, the inner ring of the turntable 320 is also equipped with a wire feeding tube 370. Each wire storage disc 330 on the rear wire feeding mechanism 310 is led out through its respective transition wire ring 340 and passes through the wire feeding tube 370 and is pulled to the wire dividing ring 350. The wire feeding tube 370 plays a role in gathering and guiding the multiple strands of steel wire led out from the rear wire feeding mechanism 310, so that they can be pulled to the wire dividing ring 350 according to a specific path, ensuring that there is no interference with the steel wire led out from the front wire feeding mechanism 300, thereby improving the reliability and stability of the wire feeding process.

[0058] Preferably, the front end of the guide ring 360 is further provided with a wire locking mechanism 380, which includes:

[0059] The locking ring seat 381 has a mounting base 382 at its bottom, and the locking ring seat 381 can move back and forth on the mounting base 382 to adjust its position.

[0060] The locking ring 383 is installed on the locking ring seat 381. The pipe passes through the locking ring 383, and the steel wire led out from the guide ring 360 is pulled into the space formed by the outer diameter and the inner hole of the locking ring 383, so that the steel wire is pressed tightly against the outer wall of the pipe and evenly distributed.

[0061] Specifically, the steel wires, which are pressed and evenly distributed by the locking ring 383, are spirally wound around the outer wall of the pipe. Through the configuration of left and right spiral winding devices, a steel wire mesh composite reinforcement layer is formed covering the surface of the pipe. By replacing the locking ring 383 and adjusting the front and rear positions of the locking ring seat 381, the device can be adapted to winding pipes with different outer diameters, thereby improving the versatility and adaptability of the winding device.

[0062] Preferably, the mounting frame 100 further includes a frame 120, wherein the mounting plate 110 is mounted on the frame 120, the support wheel 130 provides auxiliary support for the mounting plate 110, the turntable 320, etc., and the mounting base 382 is fixed on the frame 120.

[0063] In addition, the winding device in this embodiment is also applicable to non-metallic wire (bundle) reinforcing materials.
