Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing and transportation, and in particular to a transportation device for polyethylene winding processing of thermal insulation pipes. Background Art

[0002] Spray-wrap polyurethane pipe insulation technology originated in Europe and was later adopted in the United States. In recent years, the technology has been widely used internationally, and the spray coating method has seen significant development. The process begins with an anti-corrosion treatment on the steel pipe, which is then sent to the spraying area. The foamed polyurethane raw materials are mixed and sprayed onto the steel pipe surface under high pressure. After the polyurethane foam solidifies, a polyethylene film is extruded from a polyethylene extruder in the wrapping area. Multiple layers of polyethylene film are then wrapped around the outer layer of the polyurethane foam, and the pipe is then cooled with water to form a composite insulated pipe. However, existing polyurethane insulated pipes are generally relatively heavy, making manual loading and unloading operations inefficient and time-consuming. Using a crane for lifting and transporting the pipes requires a large space and is costly. This approach fails to achieve efficient and convenient automated loading and unloading operations while also achieving high cost-effectiveness and resource allocation. Further analysis reveals that in actual polyethylene film wrapping operations for polyurethane insulated pipes, most manufacturers typically use a clamp to clamp and rotate the outer ends. However, this method requires a larger clamp structure for larger insulated pipes, resulting in high costs. At the same time, external clamping requires a sufficiently large clamping force. For the insulation pipe, a large and unreasonable clamping force is also prone to deformation at the end, resulting in defects in the insulation pipe processing quality. Moreover, the external clamping method will also cause a blind spot in the polyethylene film winding, that is, the position of the clamping end of the insulation pipe cannot be wound, and this area cannot be used, resulting in a waste of insulation pipe resources. At the same time, the polyethylene winding process and the cooling process in most factories are separated, and the insulation pipe still needs to be transported again, which is time-consuming and labor-intensive, and the space utilization is not reasonable. In other words, it is impossible to achieve the insulation pipe processing quality and efficient resource utilization effect on the basis of reasonable and efficient tightening, supporting and rotating operations of the insulation pipe. At the same time, the insulation pipe winding process and cooling process can also be structurally upgraded and transformed to save time and labor, and improve the insulation pipe winding operation transportation efficiency and processing quality. For this reason, we need a conveying equipment for polyethylene winding processing of insulation pipes. Summary of the Invention

[0033] Example: Figures 1 to 10 As shown:

[0034] A conveying device for polyethylene winding processing of thermal insulation pipes, comprising a support seat 1, a hoisting mechanism 2, a winding mechanism 3 and a cooling mechanism 4; the present invention has a reasonable structural design, and can complete efficient, convenient and automated loading and unloading operations, while optimizing the internal support fastening structure, ensuring the processing quality of the thermal insulation pipe, simplifying the processing procedures, and improving the efficiency of the thermal insulation pipe winding operation. Among them, the support seat 1 is distributed on the left and right; support legs can be set at the bottom for support. A movable mounting seat 5 is also provided on the support seat 1, and the mounting seat 5 itself remains extended forward and backward. The mounting seats 5 are two symmetrically distributed on the left and right, and can complete the operation of the two mounting seats 5 approaching or moving away synchronously. Specifically, as Figure 4 and Figure 5 As shown, the bottom surface of the mounting base 5 is provided with a slot 51, and the upper surface of the support base 1 is mounted with a support rail 52, which mates with the slot 51. The support rail 52 is secured to the support base 1 with screws. This arrangement allows the mounting base 5 to move left and right along the support rail 52. Two auxiliary plates 11, located on the left and right sides of the support base 1, are also provided; they can be welded together and secured. A movable motor 12 is mounted on one side of the support base 1 via a bracket. This servo-controlled motor provides more precise displacement control. The output end of the movable motor 12 is connected to a rotating shaft 13, which is located on the left and right sides. The rotating shaft 13 also has two threaded portions 14 with opposite rotation directions. The rotating shaft 13 passes through the auxiliary plate 11 and the mounting base 5, and is connected to the auxiliary plate 11 via a bearing. The two threaded portions 14 of the rotating shaft 13 are each connected to a corresponding mounting base 5. In this embodiment, the conveying device is electrically powered by connecting an external power supply via a wire.

[0035] The purpose of such a setting is that when the mobile motor 12 starts to rotate forward, the rotating shaft 13 starts to rotate clockwise. Since the two threaded parts 14 of the rotating shaft 13 are respectively connected to the two mounting seats 5, the auxiliary cooperation of the supporting slide rail 52 and the card slot 51 plays a good guiding and limiting role. Therefore, the rotating shaft 13 will drive the two mounting seats 5 to move closer together, which corresponds to the loading and tightening operation state of the insulation pipe. When the mobile motor 12 starts to reverse, the rotating shaft 13 starts to rotate counterclockwise. Since the two threaded parts 14 of the rotating shaft 13 are respectively connected to the two mounting seats 5, the rotating shaft 13 will drive the two mounting seats 5 to start moving away from each other synchronously, which corresponds to the unlocking and unloading operation state of the insulation pipe. The present invention can be widely used in the winding processing operations of insulation pipes of different lengths, specifications and models, and has stronger adaptability.

[0036] like Figure 5 As shown: In this embodiment, each mounting seat 5 is provided with an inner support 6 for completing the inner support, fastening and rotation of the insulation pipes of different diameters. Specifically, Figure 9 and Figure 10 As shown: the internal support member 6 includes a first motor 61, a first shaft 62, a limit plate 63, a second shaft 64, a second drive 65, a base plate 66, a movable sleeve 67 and an internal support structure 68. The first motor 61 is arranged on the mounting seat 5 through a bracket, and the first motor 61 also adopts a servo control motor. The first shaft 62 is rotatably arranged on the mounting seat 5, and one end is connected to the first motor 61, and the other end is fixedly installed with the limit plate 63; the purpose of such arrangement is to realize the rotation operation of the first motor 61 driving the first shaft 62. The second shaft 64 is relatively rotatably mounted on the first shaft 62, and the second shaft 64 is connected to the mounting seat 5 through a bearing. The purpose of such arrangement is to ensure that the rotation of the first shaft 62 does not affect the state of the second shaft 64, and to provide a strong foundation for the subsequent automated center positioning internal support drive of the insulation pipe.

[0037] like Figure 5As shown, the second drive 65 is used to drive the second shaft 64 to rotate. In a preferred embodiment, the second drive 65 includes a driving wheel 651, a driven wheel 652, and a second motor 653. The second motor 653 is fixedly mounted to the mounting base 5 via a bracket. The second motor 653 can be a servo-controlled motor. This configuration aims to ensure the rotation of the second shaft 64, and therefore the rotation speed of the second shaft 64 and the insulation pipe as a whole. To achieve the best quality of polyethylene film wrapping of the insulation pipe, the rotation speed of the insulation pipe must be precisely controlled. Since the required rotation speed varies for insulation pipes of different diameters, the second motor 653 can also be a variable frequency motor to achieve adjustable rotation speed. The driving wheel 651 is sleeved and mounted on the output shaft of the second motor 653. In this configuration, the second motor 653 drives the driving wheel 651 to rotate synchronously. The driven wheel 652 is fixedly mounted on the second shaft 64, and the driving wheel 651 and the driven wheel 652 maintain meshing transmission. With this arrangement, the rotation of the second motor 653 drives the rotation of the second shaft 64 through the cooperation of the driving wheel 651 and the driven wheel 652. Figure 10 As shown, the base plate 66 is circular and fixedly mounted on the second shaft 64, and is located inside the mounting base 5. The movable sleeve 67 is movably mounted on the second shaft 64, and one side is threadedly connected to the first shaft 62; that is, the movable sleeve 67 can move relative to the second shaft 64, and the rotation of the first shaft 62 will drive the movement of the movable sleeve 67.

[0038] The present invention adopts the cooperation of the first motor 61, the first shaft 62, the limit plate 63, the second shaft 64, the second drive 65, the base plate 66, the movable sleeve 67 and the internal support structure 68. On the basis of realizing reasonable and efficient tightening, supporting and rotating operations of the insulation pipe, it can complete polyethylene winding without blind spots and dead angles, and can achieve the purpose of improving the processing quality of the insulation pipe and fully utilizing the pipeline resources. The manufacturing process is simplified and the dynamic balance of the structure is improved. Compared with the clamping of the insulation pipe with the same tightening effect, on the basis of ensuring sufficient tightening and rotation of the insulation pipe, the uniformity of the insulation pipe support is improved, and there is no problem of end clamping deformation and the inability to utilize the blind spots of the winding processing. The utilization rate of the insulation pipe material can be increased by 5% at most.

[0039] like Figure 10As shown: In this embodiment, the inner support structure 68 is used to complete the inner support and tightening operation of the insulation pipe. Specifically, the inner support structure 68 is a plurality of groups evenly distributed in a ring shape, and preferably four groups are used in this embodiment. Each group of the inner support structure 68 includes a linkage rod 681, an inner support rod 682 and a moving block 683. One end of the linkage rod 681 is rotatably connected to the movable sleeve 67, and the other end is rotatably connected to the inner support rod 682. Among them, the outer end surface of the inner support rod is arc-shaped, and the inner end surface is a planar structure. A moving groove 684 is provided on the base plate 66; the moving block 683 is adapted to be installed in the moving groove 684, and the moving block 683 is connected and fixed to the inner support rod 682, and is L-shaped as a whole. With this arrangement, the moving block 683 cooperates with the moving groove 684 to form a good guiding and limiting effect, the purpose of which is to realize the contraction and outward expansion movement of the inner support rod 682. Specifically, once the insulated pipe has been delivered to the designated position on the support base 1, it is positioned along the left-right central axis of the support base 1. Initially, the centers of the two mounting bases 5 and the two inner supports 6 are located on the left-right central axis of the support base 1; the two inner supports 6 are at their maximum distance from each other. The inner diameter of the insulated pipe is sufficiently large, allowing the inner supports 6 of this embodiment to be designed to accommodate this.

[0040] Initially, the inner support rods 682 are fully retracted. The moving motor 12 then starts rotating forward, and the two mounting bases 5 begin to approach each other until the inner support rods 682 of the inner support member 6 are fully inserted into the insulation tube (this can be achieved through the auxiliary position limiting function of the base plate 66). At this point, the left and right inner support members 6 are positioned at opposite ends of the insulation tube. Next, the first motor 61 is activated, driving the first shaft 62 to rotate synchronously. The second shaft 64 remains stationary. The rotation of the first shaft 62 will drive the movement of the movable sleeve 67 threadedly connected to it. Specifically, the first motor 61 rotates forward, and the first shaft 62 rotates clockwise. Under the cooperation of the movable block 683 and the movable groove 684, the movable sleeve 67 will be driven to move along the second shaft 64 toward the base plate 66. At this time, the inner support rod 682 on the movable sleeve 67 will be driven to expand outward, thereby achieving the support and tightening operation of the inner wall of the insulation pipe. Since multiple inner support rods 682 move synchronously, it can also achieve the automatic centering and supporting operation of insulation pipes of different inner diameters, which is more stable. At the same time, the inner support rod 682 has a sufficiently large plate structure, which greatly enhances the inner support and tightening effect of the insulation pipe. Next, turn on the second motor 653, and the second motor 653 will drive the second shaft 64 to rotate. At this time, the second shaft 64 forms an integrated structure with the inner support structure 68 and the insulation pipe. Therefore, the rotation of the second shaft 64 drives the inner support rod 682 and the insulation tube as a whole to rotate at a preset speed, thereby completing the efficient polyethylene film winding process. Similarly, after the insulation tube completes the winding process and cooling process, the second motor 653 is turned off and the first motor 61 is turned on and reversed, achieving the reverse movement of the movable sleeve 67, thereby completing the contraction movement of the inner support rod 682 and unlocking the insulation tube. Next, the movable motor 12 reverses, driving the mounting base 5 and the inner support member 6 as a whole away from each other. At this time, the movement of the insulation tube is free of interference, facilitating subsequent lifting, moving and conveying operations.

[0041] like Figure 1 As shown: In this embodiment, the hoisting mechanism 2 is used to drive the insulated pipe to be processed to rotate clockwise from the preset processing area to a preset angle to complete the loading and conveying operation, and can drive the insulated pipe after winding to continue to rotate clockwise to a preset angle to complete the unloading and conveying operation of the preset finished product area. Preferably, as Figure 3 As shown: the hoisting mechanism 2 includes a hoisting base 21, a rotating base 22, a fixed column 23, a traction arm 24, a hydraulic cylinder 25 and a lifting claw 26. The hoisting base 21 is vertically distributed, as shown in FIG. Figure 1As shown, the hanging base includes an end face and four supporting leg structures arranged at the lower end of the end face. The rotating base 22 is set on the hanging base 21 through a bearing, that is, the rotating base 22 and the hanging base 21 can rotate relative to each other but cannot move relative to each other. A vertically distributed rotating shaft 74 is set at the bottom end of the rotating base 22, and the two can be fixed by welding. The hanging base 21 is also equipped with a rotating motor 71 through a bracket. The rotating motor 71 can use a servo control motor to facilitate precise control of the rotation angle, such as Figure 2 As shown: In this embodiment, a material loading area to be processed (SL area in the figure) is set in front of the hoisting base 21, and a finished product unloading area (XL area in the figure) is set behind the hoisting base 21. At the same time, this embodiment can use the initialization setting of the rotating motor 71 to a single clockwise turning angle of 90 degrees, that is, to drive the traction arm 24 to turn 90 degrees clockwise. Taking the traction arm 24 located in the material loading area to be processed as the reference 0 degree as an example, the rotating motor starts to turn 90 degrees once, which will drive the traction arm 24 to rotate 90 degrees clockwise, thereby completing the loading operation of the insulation pipe material. At the same time, the rotating motor of this embodiment can also cooperate with the position sensors distributed at the four corners of the hoisting base 21 to achieve precise position rotation. As shown Figure 3 As shown: the output shaft of the rotating motor 71 is installed with the first wheel 72, and the second wheel 73 is installed on the rotating shaft 74, and the first wheel 72 and the second wheel 73 are kept in meshing transmission; the purpose of such arrangement is that when the rotating motor 71 is started, the first wheel 72 will be driven to rotate synchronously, and then the second wheel 73 and the rotating seat 22 are synchronized with each other under the meshing transmission action of the first wheel 72 and the second wheel 73, and the whole rotation process maintains smooth steering and steady speed.

[0042] like Figure 3As shown in this embodiment, the fixed column 23 is vertically mounted and welded to the rotating base 22 at its bottom end. To enhance stability, multiple circular reinforcement ribs 27 may be provided between the two. The traction arm 24 is vertically mounted to the fixed column 23, with reinforcement ribs 27 also provided between the two. This arrangement ensures sufficient stability for the traction arm 24. The hydraulic cylinder 25 is vertically mounted, with one end connected to the traction arm 24 and the other end connected to the lifting claw 26. This arrangement allows the lifting claw 26 to be raised and lowered by the expansion and contraction of the hydraulic cylinder 25. In a preferred embodiment, the lifting claw 26 comprises a cross arm 261, a connecting arm 262, and a hydraulic clamping claw 263. The cross arm 261 is mounted at the lower end of the hydraulic cylinder 25, and the two are vertically mounted. The cross arm 261 and the hydraulic cylinder 25 can be connected by a connector. One end of the connector is welded to the hydraulic cylinder 25, and the other end is bolted to the cross arm 261. Both ends of the cross arm 261 are provided with fixing slots 264; the cross arm 261 is sufficiently long, and the fixing slots 264 are also sufficiently deep. The connecting arm 262 is L-shaped, with one end inserted into the fixing slot 264 of the cross arm 261 and connected and secured by a fastening bolt 265. The hydraulic clamping jaws 263 are provided on the connecting arm 262. The hydraulic clamping jaws 263 utilize the mechanical hydraulic gripping arm at the front end of the loader equipment. Specifically, the two clamping jaws are hinged and each is driven by a corresponding hydraulic cylinder to achieve opening and closing gripping operations. This is prior art and will not be described in detail here.

[0043] Initially, the traction arm 24 is positioned directly above the loading area. The relative lengths of the cross arm 261 and the connecting arm 262 are adjusted to accommodate the transport and loading requirements of insulated pipes of varying lengths. Initially, the hydraulic jaws 263 remain open. The operator activates the hydraulic cylinder 25 to extend, bringing the hydraulic jaws 263 closer to the insulated pipe. The hydraulic jaws 263 are then activated to secure the pipe. Next, the hydraulic cylinder 25 is activated to retract, raising the hydraulic jaws 263 and the insulated pipe to a predetermined height. Next, the rotary motor is activated. For example, with the traction arm 24 positioned in the loading area at 0 degrees, a 90-degree rotation of the rotary motor causes the traction arm 24 to rotate 90 degrees clockwise, effectively transporting the insulated pipe directly above the support base 1. Next, the hydraulic cylinder 25 descends, unloading the pipe, and then rises to its initial height, ensuring the polyethylene film wrapping process is complete. This completes the loading of the insulated pipe material and provides a strong foundation for subsequent polyethylene film wrapping and cooling operations. After the polyethylene film wrapping and cooling processing of the insulation pipe is completed, the hydraulic cylinder 25 starts to extend, and after completing the gripping operation of the insulation pipe, it rises and resets. The next step is to start the rotating motor to drive the traction arm 24 to continue to turn 90 degrees clockwise to the unloading finished product area, and then move down to complete the unloading and conveying operation of the insulation pipe. The present invention further adopts the cooperation of the lifting base 21, the rotating seat 22, the fixed column 23, the traction arm 24, the hydraulic cylinder 25 and the lifting claw 26 to achieve efficient and convenient automated loading and unloading operations while achieving the purpose of high cost performance and reasonable resource allocation, thereby improving the winding and conveying efficiency of the insulation pipe.

[0044] like Figure 1 As shown: In this embodiment, the winding mechanism 3 includes a moving seat 31, a side wing plate 32, a screw 33, a guide rod 34, a drive motor 35 and a base 36. The moving seat 31 is arranged on the support seat 1 so as to be movable forward and backward; in a preferred technical solution, as shown in FIG. Figure 6As shown: the lower end of the movable seat 31 is provided with a fixed block 311 and a protrusion 312, wherein the protrusion 312 is located at the center of the movable seat 31, and the fixed block 311 is located on the outside of the protrusion 312. The support seat 1 is provided with a fixed slide rail 38, and the two are fixed by screws, and the fixed slide rail 38 maintains the front and rear extension. The fixed block 311 is installed in matching with the fixed slide rail 38; the purpose of such an arrangement is to play a good guiding and moving role. The support seat 1 is also provided with a support plate 15, and the support plates 15 are distributed in front and back in two, and the purpose is to provide a support carrier for the rotating rod 17. The support seat 1 is also provided with a fixed motor 16, and the fixed motor 16 is installed on the support seat 1 through a bracket, and a rotating rod 17 is also connected to one end. The rotating rod 17 is connected to the support plate 15 through a bearing, and is threadedly connected to the protrusion 312. The purpose of this arrangement is to accommodate polyethylene winding operations for insulated pipes of varying outer diameters, thereby avoiding the problem of larger diameter insulated pipes being closer to the polyethylene film and smaller diameter insulated pipes being farther away from the polyethylene film, which causes pulling and affects the irrational spraying of the coolant. Specifically, the distance between the polyethylene film and the insulated pipe is adjusted by adjusting the front and rear position of the movable seat 31. Specifically, the forward rotation of the fixed motor 16 drives the rotating rod 17 to rotate clockwise. With the cooperation between the fixed slide rail 38 and the fixed block 311, the rotating rod 17 drives the movable seat 31 toward the front of the support seat 1. This corresponds to the adjustment of the operation close to the insulated pipe, corresponding to the winding and cooling operations for insulated pipes with smaller outer diameters. Conversely, the reverse rotation of the fixed motor 16 drives the movable seat 31 backward, corresponding to the adjustment of the operation away from the insulated pipe, corresponding to the winding and cooling operations for insulated pipes with larger outer diameters. This achieves the rational utilization of resources and improves the processing quality and operating efficiency of the insulated pipes.

[0045] like Figure 6 As shown: In this embodiment, there are two side wing plates 32 symmetrically distributed on the left and right, and both are arranged on the movable seat 31; the two can be fixed by welding. The screw 33 is rotatably installed on the two side wing plates 32 distributed on the left and right; bearings can be provided at the connection between the two. The driving motor 35 is installed on one side of the side wing plate 32 through a bracket and is connected to the screw 33; the driving motor 35 also adopts a servo control motor, the purpose of which is to accurately and smoothly control the rotation speed, and then adapt the speed requirement of the insulation pipe through the moving speed of the polyethylene film to ensure the winding processing quality of the polyethylene film. The guide rod 34 is arranged between the two side wing plates 32 and is arranged parallel to the screw 33; the base 36 is arranged on the screw 33 and the guide rod 34, and is threadedly connected to the screw 33 and slidably connected to the guide rod 34; as shown Figure 7As shown: an L-shaped winding rod 37 is also provided on one side of the base 36 for installing a roll of polyethylene film. With this arrangement, the guide rod 34 plays a guiding role. When the polyethylene winding process is performed on the insulation pipe, the drive motor 35 starts to rotate forward, thereby driving the screw 33 to rotate clockwise. Under the limiting and guiding action of the guide rod 34, the screw 33 will drive the base 36 to move smoothly to the right until all the winding processes on the insulation pipe are completed, without dead angles or residues, and the entire length of the insulation pipe can be utilized. In a preferred embodiment, as Figure 8 As shown, a baffle 361 is hingedly mounted on one side of the base 36. A compression spring 362 is provided on the side of the baffle 361 away from the winding rod 37. This spring maintains the initial state of the baffle 361 pressing the rolled polyethylene film on the winding rod 37. This arrangement facilitates the feeding and conveying of the polyethylene film while ensuring that the polyethylene film is pressed tightly to prevent it from dislocating or slipping.

[0046] like Figure 8 As shown: In this embodiment, the cooling mechanism 4 includes a cooling chamber 41, a liquid pump 42 and a cooling nozzle 43. The cooling chamber 41 is opened inside the base 36 and is connected to an infusion tube, which leads to the outside. There is enough coolant in the cooling chamber 41. The liquid pump 42 is fixedly installed in the cooling chamber 41 by a bracket, and the cooling nozzle 43 is arranged on the base 36, with one end connected to the liquid pump 42 and the other end facing the insulation pipe. The cooling nozzle 43 and the winding rod 37 are both located in the middle of the base 36, and can spray the corresponding insulation pipe to ensure sufficient uniformity and rationality of resource utilization. In a preferred technical solution, the side wing plate 32 can be set as a structure that can be raised and lowered and adjusted, the purpose of which is to always ensure that the cooling nozzle 43 is located in the middle of the insulation pipe. The present invention has a reasonable structural design, and the coolant spraying cooling process is integrated into the polyethylene film installation location, which simplifies the processing process, saves space, and has a compact structure. Compared with the winding and cooling processes with the same effect, the space is saved by more than 50%, and the material is saved by about 25%, thereby effectively reducing the manufacturing cost. At the same time, since the cooling is carried out next to the winding, there is no need to transport the insulation pipe, and efficient cooling can be completed quickly after the polyethylene winding, thereby greatly improving the efficiency and processing quality of the polyethylene winding process.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
