Description

Technical Field

[0001] This invention belongs to the field of manufacturing equipment for hose body reinforcement layers, specifically relating to winding reels, winding heads, winding machines, and braiding machines. Background Technology

[0002] Existing tubing reinforcement layer winding and braiding machines generally include the following systems: power source, transmission system, winding / braiding unit, traction device, and support system (including frame, nozzle, etc.). The power system drives the spindle on the winding / braiding unit to rotate around the tubing at a certain speed via the transmission system. The spindle then unwinds the reinforcing wire (steel wire, cotton thread, or other fiber filaments) under a certain tension, winding or braiding it onto the tubing surface according to a specific pattern to form the tubing reinforcement layer. The traction device pulls the tubing at a certain speed to ensure the winding or braiding angle of the reinforcing wire (theoretical equilibrium angle is 54°44′). During the winding or braiding process, the tension control of the reinforcing wire and the coordination between the spindle speed and the tubing traction speed are crucial to the quality of the hose manufacturing. They affect the uniformity and angle of the reinforcing wire arrangement, thus influencing the stress state and pressure resistance of the tubing reinforcement layer. Existing winding and braiding machines still have the following shortcomings: 1. The tension compensation mechanism or friction clutch on the spindle is complex, and the accuracy, sensitivity, and stability of tension control are not high enough; 2. The replacement of the spindle wheel and the adjustment of tension are not convenient; 3. The spindle wheel has a small yarn capacity when fully loaded, requiring frequent yarn changes and affecting production efficiency; 4. The tension compensation mechanism or friction clutch is troublesome to replace or maintain after wear; 5. Tension calibration is too frequent, affecting production efficiency; 6. It can only produce tubes of the same diameter and cannot adapt to the production of tubes of varying diameters. Summary of the Invention

[0003] To address the problems existing in the spindle assemblies of current winding and braiding machines, this invention proposes a structural improvement and provides a novel spindle assembly, as follows:

[0004] The novel spindle assembly includes a spindle wheel, a spindle plate, a main shaft, and a tension control device. The spindle wheel and spindle plate are both mounted on the main shaft. The tension control device includes an axial compensation mechanism, a tension lever, a tension lever support mechanism, and a tensioning mechanism. The axial compensation mechanism, mounted on the main shaft, generates a braking torque acting on the spindle wheel. The tension lever is rotatably supported on the tension lever support mechanism. One end of the tension lever is connected to the axial compensation mechanism, and the other end is connected to the tensioning mechanism. The tensioning mechanism is used to tension the reinforcing wire, and the tension of the tensioning mechanism changes with the braking torque of the spindle wheel.

[0005] Furthermore, the axial compensation mechanism includes a friction plate, a spring seat, a tension spring, and a spring baffle. The spring seat is axially slidable but not rotatable around the main shaft and is fixed on the main shaft. The spring baffle is fixed on the main shaft and cannot be axially moved. The tension spring is disposed between the spring baffle and the spring seat. The friction plate is disposed on the side of the spring seat near the spindle wheel. The side of the spindle wheel near the spring seat is also provided with a friction plate.

[0006] Furthermore, a pin is provided at one end of the tension lever connected to the axial compensation mechanism, and a pin hole is provided on the spring seat, with the pin being assembled in the pin hole.

[0007] Furthermore, the tensioning mechanism includes a tension wheel, guide wheel I, and guide wheel II. The tension wheel is rotatably mounted on the other end of the tension lever, and guide wheel I and guide wheel II are rotatably mounted on the guide wheel mounting bracket.

[0008] Furthermore, it also includes a secondary shaft, on which both the tension lever support mechanism and the guide wheel mounting bracket are mounted.

[0009] Furthermore, the tension lever support mechanism includes a support beam with a hinge hole, a tension lever with a fixing hole, and a rotating shaft passing through the hinge hole and the fixing hole.

[0010] Furthermore, it also includes a guide rod and a guide cylinder. The guide rod is fixed between the two spindle plates and arranged parallel to the main shaft, and the guide cylinder is rotatably mounted on the guide rod.

[0011] Furthermore, the spring seat is also provided with an anti-rotation hole, through which the guide rod passes.

[0012] Furthermore, the spindle wheel is provided with end caps at both ends, and one end cap is provided with gear teeth.

[0013] Furthermore, there are multiple sets of spindle wheels and tension control devices, which are connected in series and share the same spindle.

[0014] Because the installation position and usage status of the friction plate and tension spring are relatively stable, the wear of the friction plate has a small impact on the tension. The setting of the tension lever further reduces the impact of such fluctuations on tension stability and improves the anti-interference capability of the tension adjustment mechanism. Therefore, after the spindle assembly of this invention has been adjusted and calibrated once, there is no need to repeatedly adjust and calibrate the tension within the service life of the friction plate. This avoids the trouble of repeatedly adjusting and calibrating the tension every time the spindle is replaced, as required by the prior art, and improves production efficiency.

[0015] The present invention also provides a second solution:

[0016] The winding disc includes a disc surface, a connecting plate, and multiple sets of the aforementioned spindle assemblies, with one end of the spindle assembly's main shaft fixed to the disc surface and the other end fixed to the connecting plate.

[0017] Furthermore, the connecting plate is provided with a branch hole.

[0018] Furthermore, the connecting plate is also provided with a cage wire divider, which includes a guide plate, a mouth-shaped device, and guide posts. The mouth-shaped device is provided with a smooth, flared lip surface. The guide plate and the mouth-shaped device are respectively fixed at both ends of the guide posts and are coaxial with the winding disc. The guide posts are cylindrical rods. Several guide posts are spaced at a certain distance and are evenly distributed around the axis of the winding disc. The distance between them is greater than the diameter of the reinforcing wire, and the number of their spacing corresponds to the number of wire dividing holes on the connecting plate of the winding disc.

[0019] Furthermore, the mouthpiece includes a mouthpiece plate and a mouthpiece. The mouthpiece plate is provided with an adjustment hole. The flared, smooth lip surface is disposed at one end of the cylindrical mouthpiece. The mouthpiece is coaxially fitted in the adjustment hole of the mouthpiece plate and the position of the mouthpiece can be adjusted axially.

[0020] Furthermore, the winding disc is also provided with a mandrel retainer, which is rotatably and coaxially fixed to the connecting plate; the mandrel retainer is provided with two clamping wheels, and the outer circumferential surfaces of the two clamping wheels form a space for wrapping the mandrel.

[0021] Furthermore, the mandrel holder is provided with an elastic plate, and the clamping wheel is rotatably mounted on the elastic plate.

[0022] Furthermore, mandrel retainers are provided on both sides of the connecting plate.

[0023] Furthermore, spindle assemblies are mounted on both sides of the disc.

[0024] The present invention also provides a third solution:

[0025] The winding head includes the winding disc and the machine head. The machine head includes a slewing bearing and a machine body. The slewing bearing is fixedly connected to the machine body through a support component. The winding disc is fixed on the rotating component of the slewing bearing through the disc surface. The rotating component of the slewing bearing is provided with a rotating tooth. The machine body is provided with a drive gear, which meshes with the rotating tooth.

[0026] Furthermore, the winding head is connected to the frame of the winding line via a hinge.

[0027] Furthermore, the frame of the winding line includes an upper crossbeam, a lower crossbeam, a longitudinal beam, and a column. The longitudinal beam is parallel to the traction direction of the winding line and is supported by the column fixed to the ground. The upper crossbeam is horizontally fixed to the longitudinal beam of the winding line, and the lower crossbeam is horizontally fixed to the ground. The winding head is hinged to the upper crossbeam through the middle part of the upper part of the machine body, and simultaneously hinged to the lower crossbeam through the middle part of the lower part of the machine body.

[0028] Furthermore, the machine body is also equipped with fixed ear plates, and locking plates are provided on the upper and lower crossbeams, with the fixed ear plates and locking plates cooperating with each other.

[0029] Furthermore, a sliding groove is provided on the upper crossbeam, and a hoisting vehicle is slidably fitted inside the sliding groove.

[0030] The present invention also provides a fourth solution:

[0031] A winding machine, the winding machine comprising the spindle assembly as described above, or using a winding disc as described in claim 1, or using a winding head as described in claim 1.

[0032] Furthermore, a disconnection alarm device is also installed;

[0033] The disconnection alarm device shown includes an optical fiber amplifier and a PLC high-speed counter. The optical fiber amplifier is electrically connected to the PLC high-speed counter. The optical fiber amplifier is located above the squirrel cage splitter.

[0034] or,

[0035] The wire breakage alarm device is an intelligent identification camera, which is installed above the rat cage splitter.

[0036] The present invention also provides a fifth solution:

[0040] or,

[0042] The beneficial effects of this invention are:

[0044] 2. The spindle wheel is equipped with teeth, so the spindle wheel can be put into service without disassembling it.

Detailed implementation method:

[0077] The invention will be further described below with reference to the accompanying drawings.

[0078] Example 1:

[0079] like Figure 1 As shown, the novel spindle assembly includes a spindle wheel 9, a spindle plate 7, and a main shaft 8, as well as a tension control device. Both the spindle wheel 9 and the spindle plate 7 are mounted on the main shaft 8, with the spindle wheel 9 and the tension control device located between the spindle plate 7. The tension control device includes an axial compensation mechanism, a tension lever 23, a tension lever support mechanism, and a tensioning mechanism. The axial compensation mechanism is mounted on the main shaft 8 and is used to generate a braking torque acting on the spindle wheel 9. The tension lever 23 is rotatably supported on the tension lever support mechanism. One end of the tension lever 23 is connected to the axial compensation mechanism, and the other end is connected to the tensioning mechanism. The tensioning mechanism is used to tension the reinforcing wire 4, and the tension of the tensioning mechanism changes with the change in the braking torque of the spindle wheel 9.

[0080] The axial compensation mechanism includes a friction plate 11, a tension spring 13, a spring seat 12, and a spring baffle 14. The spindle wheel 9 is cylindrical in the middle and has disc-shaped end caps 9-1 at both ends. The friction plate 11 is mounted on the outer end face of one end cap 9-1, and the friction plate 11 is coaxial with the spindle wheel 9. The two ends of the main shaft 8 are fixedly connected by spindle plates 7. The spring baffle 14, tension spring 13, spring seat 12, and spindle wheel 9 are coaxially mounted on the main shaft 8 between the two spindle plates 7. The spring seat 12 is equipped with a bearing 10, which is a sliding bearing or a linear bearing. The friction plate 11 is mounted on the end face of the spring seat 12 and is coaxial with the bearing 10. The spring seat 12 is mounted on the main shaft 8 through the bearing 10 and can slide along the axial direction of the main shaft 8. The spindle wheel 9 is mounted on the main shaft 8 through the bearing, which restricts the spindle wheel 9's freedom of movement along the axial direction of the main shaft 8, so that the spindle wheel 9 can rotate around the axis of the main shaft 8 but cannot slide along the axial direction of the main shaft 8. The tension spring 13 is compressed and assembled between the spring baffle 14 and the spring seat 12, while restricting the degree of freedom of the spring baffle 14 to move axially along the main shaft 8. This prevents the spring baffle 14 from moving axially along the main shaft 8 under the thrust of the tension spring 13, thereby causing the spring seat 12 to slide along the main shaft 8 toward the spindle wheel 9 under the thrust of the tension spring 13. This further presses the friction plate 11 mounted on the spring seat 12 against the friction plate 11 mounted on the spindle wheel 9, thereby generating a squeezing force on the contact surface of the two friction plates 11. When the spindle wheel 9 rotates around the axis of the main shaft 8, the friction plate 11 mounted on the spindle wheel 9 will rotate synchronously around the main shaft 8 under the drive of the spindle wheel 9. The friction plate 11 mounted on the spring seat 12 is constrained by the spring seat 12 and cannot rotate around the main shaft 8, remaining relatively stationary. This generates a relative sliding friction force between the contact surfaces of the two friction plates 11, and this sliding friction force acts on the spindle wheel 9 to form a braking torque.

[0081] In one embodiment, the spring baffle 14 and the spindle plate 7 are an integral structure, or the spindle plate 7 also serves as the spring baffle 14.

[0082] Besides the support method where the spring seat 12 is slidably supported on the main shaft 8 by a sliding bearing or a linear bearing, other existing axial sliding fit methods can also be used in practical applications to achieve the spring seat 12 being axially slidable but not rotatable around the main shaft 8. For example, a sliding groove can be opened on the main shaft 8 and a slider can be set on the spring seat 12, or a slider can be set on the main shaft 8 and a sliding groove can be opened on the spring seat 12 for axial sliding fit; or a key can be set around the main shaft 8 and a keyway can be set around the spring seat 12 for axial sliding fit, etc.

[0083] It also includes a guide cylinder 5 and a guide rod 16. The spring seat 12 is also provided with an anti-rotation hole 15. The guide rod 16 is fixed between the two spindle plates 7 and arranged parallel to the main shaft 8. The guide cylinder 5 is rotatably coaxially mounted on the guide rod 16. The guide rod 16 passes through the anti-rotation hole 15 of the spring seat 12, so that the spring seat 12 cannot rotate around the main shaft 8.

[0084] It also includes a secondary shaft 17, the two ends of which are fixedly connected by a spindle plate 7. The main shaft 8 and the secondary shaft 17 are arranged in parallel. The tension lever support mechanism includes a support beam 19 provided on the secondary shaft 17. The support beam 19 is provided with a hinge hole 19-1. The tension lever 23 is provided with a fixing hole 23-1. The rotating shaft 21 is fixed in the fixing hole 23-1 of the tension lever 23 and passes through the hinge hole 19-1 of the support beam 19, thereby hingedly assembling the tension lever 23 on the support beam 19. The tension lever 23 can swing around the hinge hole 19-1 of the support beam 19 through the rotating shaft 21.

[0085] One end of the tension lever 23 is hinged to the tension wheel 1 via the axle 18, while the other end is provided with a pin 22. Correspondingly, the spring seat 12 is provided with a pin hole 12-1, and the pin 22 fits into the pin hole 12-1. When the tension lever 23 swings around the hinge hole 19-1 of the support beam 19 via the rotating shaft 21, the spring seat 12 can be moved to slide axially along the main shaft 8 through the engagement of the pin 22 and the pin hole 12-1. In practical applications, the rotational connection between the tension lever 23 and the spring seat 12 can be varied, such as by fastening the shaft and hole, or by locking the groove and protrusion, etc., which will not be listed here.

[0086] The tensioning mechanism includes a tension wheel 1, a guide wheel 1D1, and a guide wheel 2D2. The tension wheel 1 is rotatably mounted on the tension lever 23. The guide wheels 1D1 and 2D2 are rotatably mounted on the guide wheel mounting bracket. The guide wheel mounting bracket is a fixed rod 2 mounted on the secondary shaft 17. The guide cylinder 5 is rotatably coaxially mounted on the guide rod 16. The reinforcing wire 4 wound on the spindle wheel 9 is guided by the guide cylinder 5 and the guide wheel 1D1, then passes around the tension wheel 1 to reach the guide wheel 2D2. After being guided by the guide wheel 2D2, the reinforcing wire 4 is led to the tube body, and the reinforcing wire 4 is wound or braided onto the tube body. In practical applications, the number of tension wheels and guide wheels in the tensioning mechanism can be set according to actual needs. For example, tension wheels 1 can be set to 2, and guide wheels can be set to 3. The two tension wheels 1 are arranged vertically at the lower end of the tension lever 23. The reinforcing wire 4 passes through the guide cylinder 5 and the first guide wheel, then passes around the first tension wheel to reach the second guide wheel. After being guided by the second guide wheel, it passes around the second tension wheel to reach the third guide wheel. After being guided by the third guide wheel, the reinforcing wire 4 is then guided to the tube body.

[0087] Preferably, the reinforcing filament is a steel wire or other fiber filament.

[0088] like Figure 3 As shown in the figure, I is the normal tension wheel 1 structure with a large diameter. When the reinforcing wire 4 is steel wire, if the tension wheel 1 is required to achieve the function of steel wire shaping or pre-deformation in the prior art, the structure of the tension wheel 1 needs to be changed accordingly, and the diameter of the tension wheel 1 needs to be reduced so that the steel wire is pre-deformed after passing around the tension wheel 1, which is beneficial for the steel wire to be wound onto the tube. At this time, the tension wheel 1 also plays the function of the shaping shaft in the prior art.

[0089] The principle of spindle tension control is as follows:

[0090] like Figure 1 , 4 As shown, the tension t of the reinforcing wire 4, after passing over the tension wheel 1, forms a resultant force f on the tension wheel 1. The resultant force f acts on the tension lever 23 through the wheel axle 18. Then, with the rotating shaft 21 as the fulcrum, a pulling force e is generated on the lever pin 22 through the lever principle. The pulling force e acts on the lever pin hole 12-1 of the guide cylinder 5 through the lever pin 22, thereby generating a force on the guide cylinder 5 opposite to the force g of the tension spring 13. The combined force m of the force g of the tension spring 13 and the pulling force e is the extrusion force exerted by the spring seat 12 and the friction plate 11 on the contact surface between the spindle wheel 9 and the friction plate 11. This extrusion force determines the magnitude of the tension t of the reinforcing wire 4. The larger the extrusion force m, the larger the tension t of the reinforcing wire 4, and vice versa. During the winding or braiding process of the tube body reinforcing layer, when the tension t increases, the pulling force e increases, which in turn leads to a decrease in the extrusion force m. Thus, the tension t begins to decrease again, thereby preventing the change of tension t and stabilizing it within a reasonable fluctuation range. Conversely, when the tension t decreases, the pulling force e also decreases, which in turn leads to an increase in the squeezing force m. As a result, the tension t begins to increase again, thus preventing the tension t from decreasing and maintaining the stability of the tension t.

[0091] The ratio of the lever arms L1 and L2 of tension lever 23 determines the sensitivity of tension adjustment. The larger the ratio, the greater the amplification effect on tension changes and the faster the response speed.

[0092] Furthermore, several locating pins X are provided on the end faces of the spring seat 12 and the spindle wheel 9. Correspondingly, several locating holes 11-1 are provided on the friction plate 11. The friction plate 11 is assembled onto the end faces of the spring seat 12 and the spindle wheel 9 by the engagement of the locating pins X with the locating holes 11-1. Then, the friction plate 11 of the corresponding spring seat 12 and the spindle wheel 9 is pressed together by the action of the tension spring 13 to form a pair of friction pairs. The friction plate 11 is coaxial with the main shaft 8. The end face of the locating pin X is lower than the contact surface of the two friction plates 11. After the friction plate 11 is assembled onto the corresponding end face of the spring seat 12 or the spindle wheel 9, the locating pin X restricts the relative rotation between the friction plate 11 and the corresponding end face of the spring seat 12 (or the spindle wheel 9). When the friction plate 11 wears out, it can be maintained by replacing the friction plate 11.

[0093] Furthermore, the friction plate 11 is assembled onto the end face of the spring seat 12 and the spindle wheel 9 by bonding.

[0094] Furthermore, the spindle wheel 9 is provided with end caps 9-1 at both ends, and one end cap 9-1 is provided with gear teeth 9-2. When the spindle wheel 9 finishes feeding the wire and needs to be fed back into the wire, the drive wheel of the wire guide machine can mesh with the gear teeth 9-2 of the spindle wheel 9 to drive the drive wheel to rotate and complete the feeding process, guiding the reinforcing wire 4 on the wire guide machine onto the drive wheel and entering the next feeding production cycle.

[0095] Example 2:

[0096] like Figure 8 As shown, a novel spindle assembly is formed by integrating multiple of the aforementioned spindle assemblies in series. Specifically, multiple corresponding spring seats 12 and spindle wheels 9 share the same main shaft 8 and are connected in series to form a novel spindle assembly with multiple spindle wheels 9, while also sharing a secondary shaft 17 and a guide rod 16. Its structural principle and wiring method are similar to those described above and will not be repeated here.

[0097] Example 3:

[0098] like Figure 9 As shown, a winding disc P includes a disc surface 6, a connecting plate 3, and multiple sets of spindle assemblies. Both the disc surface 6 and the connecting plate 3 have circumferentially distributed mounting holes. One end of the main shaft 8 and the auxiliary shaft 17 of the spindle assembly are fixed to the disc surface 6 through the corresponding mounting holes, while the other end of the main shaft 8 and the auxiliary shaft 17 of the spindle assembly are fixed to the connecting plate 3 through the corresponding mounting holes. This fixes both ends of the spindle assembly of the winding machine into a single unit via the disc surface 6 and the connecting plate 3, forming the winding disc P. The winding disc P is then connected to the winding machine head T via the disc surface 6. The spindle assemblies can be installed on one or both sides of the disc surface 6.

[0099] Furthermore, such as Figure 9-11As shown, the connecting plate 3 of the winding disc P is also provided with wire separating holes K and a squirrel cage wire separator F. The wire separating holes K are a set of holes evenly distributed around the axis of the winding disc P, used to separate the reinforcing wires 4 evenly distributed from the spindle assembly of the winding disc P, and their number corresponds to the number of reinforcing wires 4; the squirrel cage wire separator F includes a guide plate F-1, a mouth-shaped device F-2, and a guide post F-3, as shown. Figure 18 As shown, the mouth-shaped device F-2 is provided with a horn-shaped smooth lip surface N. The guide plate F-1 and the mouth-shaped device F-2 are respectively fixed at both ends of the guide post F-3 and coaxial with the winding plate P. The guide post F-3 is a cylindrical rod. Several guide posts F-3 are spaced at a certain distance and are evenly distributed around the axis of the winding plate P. The distance between them is greater than the diameter of the reinforcing wire 4. The number of intervals corresponds to the number of reinforcing wires 4 guided by the dividing hole K of the connecting plate 3 of the winding plate P. The reinforcing wires 4 on the spindle wheel 9 of the winding plate P pass through the dividing hole K on the connecting plate 3 respectively. They are evenly spaced by the dividing hole K into a radial arrangement that is evenly distributed along the axis of the winding plate P. After passing through the guide surface W of the guide plate F-1, they pass through the interval between the guide posts F-3 of the squirrel cage dividing device F. Finally, they are arranged on the surface of the winding mandrel after passing through the lip surface N.

[0100] Furthermore, such as Figure 18 As shown, the mouth-shaped device F-2 includes a mouth-shaped plate F-2-1 and a mouth shape F-2-2. The mouth-shaped plate F-2-1 has an adjustment hole. The horn-shaped smooth lip surface N is set at one end of the cylindrical mouth shape F-2-2. The mouth shape F-2-2 is coaxially fitted in the adjustment hole of the mouth-shaped plate F-2-1 and its position can be adjusted axially. The reinforcing wire 4 passes through the squirrel cage wire divider F and is arranged and guided to the surface of the winding mandrel through the lip surface N. The clamping force of the lip surface N on the reinforcing wire 4 is controlled by adjusting the position of the mouth shape F-2-2.

[0101] Furthermore, such as Figure 9-10 , Figure 12 As shown, a mandrel retainer D is also provided on the winding disc P. The mandrel retainer D is rotatably and coaxially fixed on the connecting plate 3 of the winding disc P via bearings. It can be provided on one side of the connecting plate 3 of the winding disc P, or on both sides of the connecting plate 3. The mandrel retainer D is also provided with two clamping wheels D-2. The outer circular rotating surfaces of the two clamping wheels D-2 symmetrically wrap around and clamp the mandrel from both sides, thereby supporting the mandrel and keeping the axis of the mandrel coaxial with the axis of rotation of the winding disc P. When the mandrel moves forward under the traction of the traction machine, the clamping wheels D-2 can roll along the surface of the mandrel.

[0102] Furthermore, the clamping wheel D-2 of the mandrel holder D is connected to the elastic plate D-1 through its rotation shaft, and then connected to the bottom plate of the mandrel holder D through the elastic plate D-1, so that the clamping wheel D-2 clamps the mandrel surface with a certain elastic clamping force and automatically adapts to changes in the diameter of the mandrel.

[0103] Example 4:

[0104] like Figure 13-14 As shown, a winding head S includes a winding disc P and a machine head T. The machine head T includes a slewing bearing 25 and a machine body 24. The slewing bearing 25 is fixedly connected to the machine body 24 through its support component 25-1. The winding disc P is coaxially fixed on the rotating component 25-2 of the slewing bearing 25 through its disc surface 6. The rotating component 25-2 of the slewing bearing 25 is also provided with a rotating tooth 25-3. The drive gear R drives the rotating tooth 25-3 to drive the rotating component 25-2 of the slewing bearing 25 to rotate. The rotating component 25-2 then drives the winding disc P to rotate through the disc surface 6 of the winding disc P.

[0105] Example 5:

[0106] like Figure 15-17 As shown, a winding head S is connected to the frame of the winding line via a hinge. The frame of the winding line includes an upper crossbeam 26, a lower crossbeam 28, a longitudinal beam 27, and a column 31. The longitudinal beam 27 is parallel to the traction direction of the winding line and is supported by the column 31 fixed to the ground. The upper crossbeam 26 is horizontally fixed to the longitudinal beam 27 of the winding line, and the lower crossbeam 28 is horizontally fixed to the ground. The winding head S is hinged to the upper crossbeam 26 via the middle part of the upper part of the body 24 of the machine head T, and simultaneously hinged to the lower crossbeam 28 via the middle part of the lower part of the body 24 of the machine head T. This allows the winding head S to rotate around the hinge axis, realizing the change of position or orientation of the winding disc P. The machine body 24 is also provided with a fixing ear plate 29, and the upper crossbeam 26 and the lower crossbeam 28 are provided with locking plates 30. After the fixing ear plate 29 and the locking plate 30 are fixed together, the position of the winding head S is completely locked and cannot be rotated, thus fixing the position of the winding disc P.

[0107] Furthermore, the winding disc P can be replaced entirely. For example... Figure 19 As shown, when the winding reel P needs to be replaced after the winding is finished, first loosen the fixing between the fixing ear plate 29 and the locking plate 30, rotate the winding head S 90 degrees so that the winding reel P faces the outside of the winding line, so as to facilitate the disassembly of the winding reel P and the removal of the winding line. After disconnecting the connection between the reel surface 6 of the winding reel P and the machine head T, the winding reel P can be removed using a special tool.

[0108] Furthermore, such as Figure 19-21As shown, a sliding groove 26-1 is also provided on the upper crossbeam 26. A hoisting vehicle M slides within the sliding groove 26-1. Roller wheels M-2 are fixedly mounted on the body M-1 of the hoisting vehicle M. The roller wheels M-2 are clamped and engaged within the sliding groove 26-1 of the upper crossbeam 26, allowing the hoisting vehicle M to slide along the sliding groove 26-1, thus achieving the hoisting function. The hoisting vehicle M is equipped with a lifting device M-3, which can be fixed to the surface 6 of the winding reel P. When the connection between the surface 6 of the winding reel P and the machine head T is disengaged, dragging the hoisting vehicle M will remove the entire winding reel P. Figure 19 As shown.

[0109] Example 6:

[0110] According to production needs, several winding heads S are connected in series on the frame of the winding line. With the help of a traction machine, it is possible to wind reinforcement layers of different specifications and different numbers of layers. Figure 22 The arrangement of the winding heads S with four reinforcing layers is shown. The number of winding heads S can be increased or decreased to adapt to different high-pressure oil pipe specifications with different numbers of layers, which will not be repeated here.

[0111] Example 7:

[0112] like Figure 18 As shown, a wire breakage alarm function is also provided. An optical fiber amplifier G is fixed above the squirrel cage splitter F. The transmitter of the optical fiber amplifier G is close to and directly facing the radially distributed reinforcing filaments 4. The optical fiber amplifier G is connected to a PLC high-speed counter. The optical fiber amplifier G emits infrared laser light that irradiates the surface of the radially distributed reinforcing filaments 4. As the radially distributed reinforcing filaments 4 rotate with the squirrel cage splitter F, each reinforcing filament 4 passes sequentially through the transmitter of the optical fiber amplifier G, thus sequentially blocking the infrared laser emitted by the optical fiber amplifier G. This triggers the PLC high-speed counter to count the passing reinforcing filaments 4. Since the reinforcing filaments 4 are taut during normal production, if a reinforcing filament 4 accidentally breaks, the broken reinforcing filament 4 will move away from the transmitter of the optical fiber amplifier G, thus failing to trigger the PLC high-speed counter to count it. Consequently, the number of reinforcing filaments 4 passing per minute recorded by the PLC high-speed counter is less than the theoretically set normal value. When the actual count differs from the theoretically set normal value, the PLC will start an alarm and stop the production line to prevent the generation of defective products. Equivalently, a disconnection alarm function can also be achieved by installing a smart recognition camera.

[0113] It should be noted that the above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Obviously, various changes can be made according to actual needs, such as changes in the frame structure, the number of transmission components, their arrangement, fit, and connection methods. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the schematic diagrams, implementation schemes, and inventive concepts of the present invention, should be included within the scope of protection of this invention.
