Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe production technology, specifically a prefabricated direct-buried thermal insulation pipe set production device. Background Technology

[0002] The development of prefabricated direct-buried insulated pipes stems from the upgraded demand for efficient insulation and convenient construction in infrastructure construction such as urban centralized heating and long-distance pipelines. With the acceleration of urbanization, the traditional pipeline insulation model, which requires on-site wrapping, has a long construction cycle, and its insulation effect is easily affected by the environment, can no longer meet the needs of large-scale, high-standard pipeline construction. Against this background, prefabricated direct-buried insulated pipes have emerged. They can not only achieve excellent energy-saving effects through high-density insulation materials (such as polyurethane) and reduce energy loss during heat medium transportation, but also adapt to complex underground environments with the corrosion resistance and aging resistance of the outer protective pipe, significantly shortening the on-site construction period and reducing the overall project cost. Today, its application has expanded from urban heating to multiple fields such as petroleum, chemical, and refrigeration, becoming an important supporting product for promoting efficient energy transmission and green infrastructure development. It also aligns with the current industry policy orientation of energy conservation, emission reduction, and improving the stability of project quality.

[0003] However, when conventional prefabricated direct-buried insulated pipes are produced in sets, it is necessary to use wire to tie the pad to the outside of the working pipe before inserting it into the outer protective pipe. This process requires the cooperation of at least two workers, which is labor-intensive and relatively inefficient.

[0004] To address these issues, this invention provides a prefabricated direct-buried insulated pipe assembly production device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a prefabricated direct-buried insulated pipe assembly production device, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated direct-buried insulated pipe assembly production device, comprising: The assembly conveyor structure is mounted on the conveyor path of the outer protective tube; The assembly conveyor structure includes a mounting frame. A partition plate, equally divided, is integrally formed at the center of the mounting frame. A through-hole is formed inside the partition plate along the path of the conveyor belt transporting the working tube. Multiple circular wheel chambers are interconnected around the periphery of the through-hole along its axis. Star-shaped wheels are rotatably fitted with bearings inside these wheel chambers. Multiple grooves for carrying pads are uniformly and integrally formed on the surface of the star-shaped wheels. Gear rings are interference-fitted on both sides of the grooves on the surface of the star-shaped wheels. The gear rings on the upper side mesh with a drive gear whose rotation is limited by the bearing inside the partition plate. One end of the drive gear protrudes from the partition plate and is connected to a drive motor bolted to the side of the partition plate via a coupling. Roller rollers are exposed and rolled inside the partition plate in the wheel chambers containing the star-shaped wheels at the rotational output position of the star-shaped wheels relative to the pads.

[0007] Preferably, the surface of the mounting bracket has through holes for assembly, and the mounting is performed on the bracket by the cooperation of bolts and through holes.

[0008] Preferably, the interior of the mounting frame is equipped with conveyor belts for conveying the working pipes in groups on both sides of the partition.

[0009] Preferably, the gear rings located on the upper side do not mesh with each other, and the gear ring located on the upper side meshes with the gear ring located on the same side below for transmission.

[0010] Preferably, the pad grooves on the side of the wheel chambers where the star wheel is located are all connected to vertical pad material channels for supplying pads, and the upper ends of the pad material channels are connected to the pad supply hopper or equipment with bolts.

[0011] Preferably, the side of the roller coating wheel is also exposed inside the adhesive tank provided inside the partition without interfering with other structures, and comes into contact with the adhesive filled inside the adhesive tank.

[0012] Preferably, the adhesive tank is equipped with an electrically controlled valve at one end near the coating roller, and the output end of the adhesive tank is connected to the adhesive supply equipment through a pipeline. Beneficial effects

[0013] This utility model provides a production device for prefabricated direct-buried insulated pipe sets. Compared with the prior art, it has the following advantages: (1) The prefabricated direct-buried insulated pipe assembly production device, through the coordinated arrangement of star-shaped wheel, gear ring, drive motor, drive gear, pad material channel, roller coating wheel, glue tank, and pipe hole, allows the pad to fall from the pad material channel into the groove of the star-shaped wheel. The drive motor drives the drive gear to rotate through the coupling. The drive gear meshes with the upper gear ring, and the upper gear ring meshes with the lower gear ring on the same side, thereby realizing the synchronous rotation of all star-shaped wheels. In addition, since the roller coating wheel is exposed in the glue tank and in contact with the glue, it can evenly coat the pad on the star-shaped wheel. Finally, the pad is attached to the outer wall of the working pipe around the pipe hole, completely replacing the traditional manual pad binding method. It does not require at least two workers to cooperate in the operation, greatly reducing the labor intensity. Through the corresponding arrangement of the conveyor belts on both sides of the internal partition of the mounting frame and the pipe hole, the working pipe can move towards the pipe hole under the continuous conveying of the conveyor belt. During this period, the automatic gluing and installation of the pad are completed simultaneously.

[0014] (2) The prefabricated direct-buried insulated pipe assembly production device, through the corresponding arrangement of conveyor belts on both sides of the internal partition of the mounting frame and the pipe hole, allows the working pipe to move towards the pipe hole under the continuous conveying of the conveyor belt. During this process, the automatic gluing and installation of the pads are completed simultaneously. The working pipe with the pads installed does not need to stop or be transferred separately and can be directly conveyed to the outer protective pipe assembly stage along the conveyor belt, which effectively shortens the process interval of the prefabricated direct-buried insulated pipe assembly production and significantly improves the overall production efficiency.

[0017] 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.

[0018] Please see Figures 1-4 A prefabricated direct-buried insulated pipe set production device, comprising: Package conveyor structure 1 is assembled on the conveyor path of the outer protective tube; The assembly conveyor structure 1 includes a mounting frame 11. The surface of the mounting frame 11 has through holes for mounting, and it is mounted on a workpiece with the cooperation of bolts and through holes. A partition 13, equally divided, is integrally provided at the center of the interior of the mounting frame 11. Conveyor belts 12 for conveying the working pipe are assembled in groups on both sides of the partition 13 inside the mounting frame 11. Through-holes 134 are opened inside the partition 13 along the path of the conveyor belts 12 for conveying the working pipe, and interconnected circumferences are provided along the axis of the through-holes 134. Multiple circular wheel chambers are provided, and star-shaped wheels 132 are rotatably fitted inside the chambers with bearings. Each star-shaped wheel 132 has a plurality of recessed grooves uniformly and integrally formed on its surface to carry pads. Gear rings 1321 are interference-fitted on both sides of the recesses on the surface of the star-shaped wheel 132. The upper gear rings 1321 do not mesh with each other, but mesh with the lower gear ring 1321 on the same side for transmission. The rotation of the upper gear rings 1321 with the mating bearings is limited by a partition plate 1. 3. The internal drive gear 1331 meshes with the gear ring 1321 in equal numbers. One end of the shaft of the drive gear 1331 passes through the partition 13 and is connected to the drive motor 133, which is bolted to the side of the partition 13, via a coupling. The pad grooves on the surface of the star wheel 132 on the side of the wheel chambers where the star wheel 132 is located are all connected to vertical pad material channels 131 for supplying pads. The upper end of each pad material channel 131 is bolted to a pad material supply hopper or equipment. In the rotating output position of the star wheel 132 on the pad, each of the wheel chambers containing the star wheel 132 has an exposed rolling coating wheel 1351 inside the partition 13. The side of the coating wheel 1351 is also exposed inside the glue tank 135 inside the partition 13 without interfering with other structures, and is in contact with the glue filled inside the glue tank 135. An electric control valve is installed at one end of the glue tank 135 near the coating wheel 1351, and the output end of the glue tank 135 is connected to the glue supply equipment through a pipeline.

[0019] The device is fixed to the frame by bolts through the through holes on the surface of the mounting bracket 11. Simultaneously, the output end of the adhesive tank 135 is connected to the adhesive supply equipment (whose adhesive quantity is controlled by an internal electronic valve) via pipeline, and the upper end of the pad material channel 131 is bolted to the pad supply equipment. After starting the drive motor 133, it drives the drive gear 1331 to rotate via a coupling. Because the drive gear 1331 meshes with the upper gear ring 1321, and the upper gear ring 1321 meshes with the lower gear ring 1321 on the same side, it drives the… All star-shaped wheels 132 rotate synchronously. The pads fall from the pad material channel 131 into the grooves of the star-shaped wheels 132. When they rotate to the coating roller 1351, they are coated with glue. At the same time, the conveyor belts 12 on both sides of the partition 13 convey the working tube to the tube hole 134. When the glued pad rotates to the periphery of the tube hole 134, it automatically adheres to the outer wall of the working tube, completing the automatic gluing and installation of the pad. The working tube with the pad can continue to be conveyed and directly fitted with the outer protective tube without manual binding, reducing labor requirements, reducing strength and improving efficiency.

[0020] In summary, through the coordinated arrangement of the star-shaped wheel 132, gear ring 1321, drive motor 133, drive gear 1331, pad material channel 131, roller coating wheel 1351, adhesive tank 135, and pipe hole 134, the pad can fall from the pad material channel 131 into the groove of the star-shaped wheel 132. The drive motor 133 drives the drive gear 1331 to rotate via a coupling. The drive gear 1331 meshes with the upper gear ring 1321, which in turn meshes with the lower gear ring 1321 on the same side, thus achieving synchronous rotation of all star-shaped wheels 132. Furthermore, since the roller coating wheel 1351 is exposed inside the adhesive tank 135 and in contact with the adhesive, it can effectively protect the star-shaped wheel 132. The pads are evenly coated with adhesive, and finally the pads are attached to the outer wall of the working pipe around the pipe hole 134, completely replacing the traditional method of manually binding the pads. This eliminates the need for at least two workers to operate the system, significantly reducing the workload. Through the corresponding arrangement of the conveyor belts 12 on both sides of the internal partition 13 of the mounting frame 11 and the pipe hole 134, the working pipe can move towards the pipe hole 134 under the continuous conveying of the conveyor belt 12. During this process, the automatic application and installation of the pads are completed simultaneously. The working pipe with the pads installed can be directly conveyed to the outer protective pipe assembly stage along the conveyor belt 12 without stopping or additional transfer, effectively shortening the process interval in the production of prefabricated direct-buried insulated pipe assemblies and significantly improving the overall production efficiency.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Working principle: During operation, the device is first fixed to the frame by bolts through the through holes on the surface of the mounting bracket 11. Simultaneously, the output end of the adhesive tank 135 is connected to the adhesive supply equipment (the adhesive supply is controlled by an electronically controlled valve inside the adhesive tank 135) via a pipeline. The upper end of the pad material channel 131 is connected to the pad material supply hopper or related equipment via bolts. After starting the drive motor 133, it drives the drive gear 1331 to rotate via a coupling. Since the drive gear 1331 meshes with the upper gear ring 1321, and the upper gear ring 1321 meshes with the lower gear ring 1321 on the same side, all the star wheels 132 rotate synchronously. The pad material falls from the pad material channel 131 into the star wheel 132. In the groove on the surface of 32, when the star wheel 132 rotates to the coating wheel 1351, because one side of the coating wheel 1351 is exposed in the glue tank 135 and in contact with the glue, the glue will be rolled onto the pad. At the same time, the conveyor belts 12 on both sides of the partition 13 will convey the working tube towards the tube hole 134. When the glued pad rotates with the star wheel 132 to the periphery of the tube hole 134, it will automatically fit against the outer wall of the working tube passing through the tube hole 134, completing the automatic gluing and installation of the pad. Finally, the working tube with the pad continues to be conveyed by the conveyor belt 12, and can be directly inserted into the outer protective tube to complete the assembly. There is no need for manual binding of the pad, which greatly reduces the need for manual cooperation, reduces the workload and improves production efficiency.
