Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, specifically a transportation machine for the production of high-pressure flexible composite pipes. Background Technology

[0002] A guide machine for high-pressure flexible composite pipe production is a device used in the continuous extrusion molding process to stably support and transport flexible pipe blanks in a semi-cured and easily deformable state. Because the pipe blanks have low strength after being laid in high-temperature and pressure-bearing structural layers, they cannot withstand their own weight. Without external support and guidance, irreversible deformation (such as flattening, bending, or interlayer peeling) will occur, leading to product scrap and production interruption. Therefore, a guide machine for high-pressure flexible composite pipe production is needed.

[0003] However, traditional guide machines usually use fixed-spacing roller groups, which are difficult to balance the clamping adaptability and buffer protection of different pipe diameters, and are prone to pipe surface damage or slippage during transport. Moreover, existing equipment often lacks the ability to adjust both height and horizontal rotation, and requires multiple machines to guide the pipes in sections, which not only increases space occupation and manual intervention costs, but also easily causes pipe twisting or joint detachment due to multiple transfers. Utility Model Content

[0004] The purpose of this invention is to provide a conveying machine for the production of high-pressure flexible composite pipes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A conveying machine for producing high-pressure flexible composite pipes includes an upper frame and a lower frame. Two sets of upper support plates are fixedly installed on the lower sides of the upper frame, and two sets of lower support plates are fixedly installed on the upper sides of the lower frame. Each set of upper and lower support plates consists of two plates. A hydraulic cylinder is fixedly installed at the bottom of each lower support plate. The output end of each hydraulic cylinder is provided with a hydraulic rod. The hydraulic rod passes through the lower support plate and connects to the bottom of each upper support plate. Sliding grooves are respectively opened on both sides of the upper frame above the upper support plates. Limit blocks are slidably installed in the sliding grooves. A spring is fixedly installed at the top of each limit block, and the top of the spring is connected to the upper side wall of the sliding groove.

[0007] Preferably, the limiting blocks are respectively equipped with support shafts via bearings, and the support shafts are fixedly installed with upper inner inclined rollers inside the upper frame. The lower frame is respectively equipped with drive shafts via bearings, and the drive shafts are fixedly installed with lower inner inclined rollers inside the lower frame.

[0008] Preferably, one of the drive shafts extends into the interior of the lower frame sidewall and is provided with a drive gear. A transmission chain is meshed with the outer side of the drive gear, and a rotating gear is meshed with the end of the transmission chain away from the drive gear.

[0009] Preferably, the rotating gear is connected to the drive motor through the output shaft of the drive motor passing through the side wall of the lower frame, and the drive motor is bolted to the outside of the lower frame and located between the hydraulic cylinders.

[0010] Preferably, the lower frame is bolted to the top of the support plate, the support plate is fixedly mounted to the top of the plunger rod, the plunger rod is located at the output end of the plunger cylinder, and the plunger rod is bolted to the top of the rotating disk.

[0011] Preferably, the rotating disk and the rotating motor are connected after the output shaft of the rotating motor passes through the top of the C-shaped frame plate. The rotating motor is fixedly installed inside the top of the C-shaped frame plate, and two support columns are fixedly installed at the opening of the C-shaped frame plate.

[0012] Preferably, the C-shaped frame plate is fixedly installed on the top of the support platform by bolts, and fixing plates are fixedly installed on both sides of the bottom end of the support platform. The fixing plates are provided with fixing holes, and the fixing holes are fixed by bolts passing through them to achieve overall fixation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This high-pressure flexible composite pipe production guide machine uses a hydraulic cylinder to drive a hydraulic rod to lift the upper frame, combined with a limit block structure with spring buffer in the sliding groove, to achieve stepless adjustment and adaptive elastic compensation of the pipe clamping distance, effectively avoiding deformation damage to the pipe body caused by rigid extrusion, while adapting to the flexible guiding needs of different pipe diameters.

[0015] 2. This high-pressure flexible composite pipe production guide machine, through the symmetrical inclined layout of the inner inclined rollers and the synchronous transmission design of the drive chain, enables the pipe to be automatically centered and prevented from deviating during the conveying process. Combined with the lifting of the plunger cylinder and the rotation adjustment function driven by the rotating motor, it realizes the coordinated adjustment of the guiding height and angle, which significantly improves the accuracy of pipe turning and guiding and the flexibility of the production line layout.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A high-pressure flexible composite pipe production guide machine includes an upper frame 101 and a lower frame 102. Two sets of upper support plates 103 are fixedly installed on the lower sides of the upper frame 101, and two sets of lower support plates 104 are fixedly installed on the upper sides of the lower frame 102. Each set of upper support plates 103 and lower support plates 104 consists of two plates. A hydraulic cylinder 105 is fixedly installed at the bottom of each lower support plate 104. A hydraulic rod 106 is provided at the output end of each hydraulic cylinder 105. The hydraulic rod 106 passes through the lower support plate 104 and connects to the bottom of each upper support plate 103. Sliding grooves 107 are respectively opened on both sides of the upper frame 101 above the upper support plates 103. Limiting blocks 108 are slidably installed in the sliding grooves 107. A spring 109 is fixedly installed at the top of each limiting block 108, and the top of the spring 109 is connected to the upper side wall of the sliding groove 107.

[0024] The above scheme provides the main support frame through the upper and lower frames. The symmetrical layout of two sets of upper support plates and two sets of lower support plates achieves force transmission balance. The extension and retraction output of the hydraulic cylinder controls the lifting and lowering movement of the hydraulic rod. The structure of the hydraulic rod passing through the lower support plate and connecting to the upper support plate directly drives the vertical movement of the upper frame, thereby producing a precise adjustment effect on the distance between the upper and lower frames. The sliding cooperation of the sliding groove and the limit block restricts the movement trajectory of the upper frame. The elastic connection of the spring absorbs vibration and impact, avoids rigid collisions, and achieves a buffer protection function during equipment operation.

[0025] In this embodiment, preferably, support shafts 110 are respectively installed between the limiting blocks 108 via bearings, and upper inner inclined rollers 111 are fixedly installed inside the upper frame 101 via bearings. Drive shafts 112 are respectively installed inside the lower frame 102 via bearings, and lower inner inclined rollers 113 are fixedly installed inside the lower frame 102 via bearings.

[0026] The above scheme ensures the flexible rotation of the upper inner inclined roller between the limit blocks by the support shaft mounted on the bearing, and forms a centrally converging clamping channel by the symmetrical inclined arrangement of the upper and lower inner inclined rollers. The active driving force is provided by the fixed connection between the drive shaft and the lower inner inclined roller, so as to keep the pipe in the center of the conveying between the inclined rollers, effectively preventing the pipe from deviating and reducing friction loss.

[0027] In this embodiment, preferably, one of the drive shafts 112 extends into the interior of the side wall of the lower frame 102 and is provided with a drive gear 114. A transmission chain 115 is meshed on the outer side of the drive gear 114, and a rotating gear 116 is meshed on the end of the transmission chain 115 away from the drive gear 114.

[0028] The above scheme transmits rotational power through a drive gear located at the extended end of the drive shaft. A chain transmission structure is formed by the drive gear meshing with the rotating gear, thereby achieving the synchronous transmission of driving force to multiple drive shafts and ensuring the stability of the coordinated rotation of the lower inner inclined roller.

[0029] In this embodiment, preferably, the rotating gear 116 and the drive motor 117 are connected after the output shaft of the drive motor 117 passes through the side wall of the lower frame 102. The drive motor 117 is bolted to the outside of the lower frame 102 and located between the hydraulic cylinders 105.

[0030] The above solution directly obtains power through a rigid connection between the rotating gear and the output shaft of the drive motor. The layout of the drive motor installed between the hydraulic cylinders on the outside of the lower frame saves space, resulting in a compact and integrated power drive, avoiding external interference and improving maintenance convenience.

[0031] In this embodiment, preferably, the lower frame 102 is bolted to the top of the support plate 118, the support plate 118 is fixedly mounted to the top of the plunger rod 119, the plunger rod 119 is located at the output end of the plunger cylinder 120, and the plunger rod 119 is bolted to the top of the rotating plate 121.

[0032] The above scheme establishes a support reference surface by connecting the support plate and the lower frame with bolts, controls the lifting and lowering movement of the plunger rod by a plunger cylinder, and forms a height adjustment mechanism by fixing the top of the plunger rod to the rotating plate with bolts, thereby achieving stepless adjustment of the vertical height of the entire equipment to meet the height requirements of different production lines.

[0033] In this embodiment, preferably, the rotating disk 121 and the rotating motor 122 are connected after the output shaft of the rotating motor 122 passes through the top of the C-shaped frame plate 123. The rotating motor 122 is fixedly installed inside the top of the C-shaped frame plate 123, and two support columns 124 are fixedly installed at the opening of the C-shaped frame plate 123.

[0034] The above scheme obtains rotational torque directly through the through-connection between the rotating disk and the output shaft of the rotating motor. The rotating motor is fixed inside the C-shaped frame plate to provide sealed protection. The rotating disk is driven by the rotating motor to rotate, thereby driving the plunger cylinder and the lower frame to rotate as a whole, so as to achieve free adjustment of the horizontal angle of the equipment. The two pillars at the opening of the C-shaped frame plate strengthen the lateral support and generate structural stability against torsional loads.

[0035] In this embodiment, preferably, the C-shaped frame plate 123 is fixedly installed on the top of the support platform 125 by bolts, and fixing plates 126 are fixedly installed on both sides of the bottom end of the support platform 125 respectively. Fixing holes 127 are provided on the fixing plates 126, and the fixing holes 127 are fixedly installed by bolts to achieve overall fixation.

[0036] The above solution uses bolts to connect and fix the C-shaped frame plate at the top of the support platform to form the main load-bearing platform. The fixing plate is then locked to the base with bolts through the fixing holes, achieving permanent anchoring of the entire equipment to the production site, eliminating the risk of operational displacement and improving vibration resistance.

[0037] In this embodiment, a high-pressure flexible composite pipe production guide machine is first used by fixing the entire structure to the base of the production site using bolts through the fixing holes 127 on the fixing plate 126 at the bottom of the support platform 125, ensuring sufficient stability and vibration resistance during operation. Next, the hydraulic cylinder 105 system is adjusted according to the diameter of the high-pressure flexible composite pipe to be guided. The hydraulic cylinder 105 is installed at the bottom of the lower support plates 104 on both sides, and the hydraulic rod 106 at the output end of the hydraulic cylinder 105 extends and passes through the lower support plate 104, directly connecting to the bottom of the upper support plate 103. When the hydraulic cylinder 105 extends or retracts, the hydraulic rod 106 pushes or pulls the upper support plate 103, thereby driving the entire upper frame 101 to move up and down relative to the lower frame 102. The movement process alters the distance between the upper frame 101 and the lower frame 102, specifically targeting the gap between the upper inner inclined roller 111 and the lower inner inclined roller 113, to accommodate pipes of different diameters and improve the equipment's versatility and adaptability. Simultaneously, a limiting block 108 is installed within the sliding groove 107 on the upper frame 101. The limiting block 108 is elastically connected to the upper sidewall of the sliding groove 107 via a spring 109. During hydraulic adjustment, the limiting block 108 slides along the sliding groove 107, while the spring 109 provides a buffering effect, absorbing impact and vibration, preventing rigid collisions caused by rapid adjustments or external loads, and protecting the pipe and internal components from damage. After the gap adjustment is completed, the pipe is positioned between the upper inner inclined roller 111 and the lower inner inclined roller 113, and simultaneously... The pipe is clamped between the upper inner inclined roller 111 and the lower inner inclined roller 113 by adjustment using hydraulic cylinder 105 and hydraulic rod 106, and spring 109 can spring back to ensure that the pipe is not over-clamped. After clamping, the drive system is activated: drive motor 117 is fixedly installed on the outside of lower frame 102, and the output shaft of drive motor 117 drives rotating gear 116 to rotate; rotating gear 116 transmits power through transmission chain 115 meshing with drive gear 114, which is fixed to the end of a drive shaft 112; the drive shaft 112 is installed inside lower frame 102 through bearings and drives the lower inner inclined roller 113 fixed thereon to rotate; the rotation of lower inner inclined roller 113 directly drives the pipe to move by friction, while the upper inner inclined roller... 111 is installed between the limiting blocks 108 inside the upper frame 101 via the support shaft 110. Since the limiting blocks 108 can slide up and down in the sliding groove 107, the upper inner inclined roller 111 can be passively rotated under the drive of the lower inner inclined roller 113, forming a clamping and conveying mechanism. The inclined design of the upper and lower rollers (i.e. the characteristics of the inner inclined roller) works together to keep the tube in the center position, prevent deviation, and maintain a stable posture during conveying, thereby reducing tube twisting or friction loss and improving the accuracy and reliability of the guiding process. If it is necessary to adjust the guiding direction or overall height to adapt to the production line layout, the equipment also provides height and angle adjustment functions: the output end of the plunger cylinder 120 is provided with a plunger rod 119, which is installed on the top of the rotating disk 121 by bolts.When the plunger cylinder 120 extends or retracts, it drives the plunger rod 119 and the upper support plate 118 to move up and down, thereby pushing the lower frame 102 to rise and fall as a whole, changing the roller height to match the pipeline processing requirements at different stages; at the same time, the rotary motor 122 is fixed to the inner top of the C-shaped frame plate 123, and the output shaft of the rotary motor 122 passes through the top of the C-shaped frame plate 123 and is connected to the rotating disk 121; when the rotary motor 122 drives the rotating disk 121 to rotate, the rotating disk 121 will drive the plunger cylinder 120, the plunger rod 119, and the entire lower frame 102 and its internal components to rotate by a specific angle, realizing multi-angle guidance or turning of the pipeline. Among them, the plunger cylinder 120 and the plunger rod 119 are radially limited and do not restrict rotation; the two support pillars 124 at the opening of the C-shaped frame plate 123 are raised. The C-shaped frame plate 123, providing lateral support, is bolted to the support platform 125, ensuring the overall stability and resistance to lateral forces during angle adjustments. Throughout the entire process, from initial fixing, hydraulic spacing adjustment, motor-driven roller rotation, to coordinated height and angle adjustments, the interaction between components is smooth and efficient. The hydraulic and spring system 109 enables stepless spacing adjustment and shock absorption, adapting to the transport of pipes of different diameters. The inner inclined roller design and continuous drive ensure stable, slip-free pipe transport. Rotation and lifting functions enhance equipment flexibility, reduce manual intervention, and improve production efficiency. The overall structure, through the fixed plate 126 and support frame, provides a foundation for long-term stable operation. Finally, the high-pressure flexible composite pipe is continuously and smoothly transported between the rollers, meeting the automated transport requirements of the production line.
