Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe production technology, and in particular to a prefabricated thermal insulation pipe spraying and winding device. Background Technology

[0002] Thermal insulation pipe is short for heat-insulating pipeline. It is mainly used for thermal insulation engineering of pipelines transporting liquids, gases or other media. It is widely used in many fields such as petroleum, chemical, aerospace, and district heating. In order to ensure the insulation effect, it is necessary to wrap the outside of the thermal insulation pipe with a heat-insulating material and spray the surface of the pipe with heat-insulating coating. The existing prefabricated thermal insulation pipe spraying and wrapping equipment can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] Existing prefabricated insulated pipe spraying and winding equipment on the market is typically equipped with a rotary drive system. High-precision rollers drive the insulated pipe to rotate at a uniform speed, ensuring the pipe enters the spraying equipment smoothly. During the spraying process, the equipment evenly sprays the insulation material onto the surface of the insulated pipe according to set parameters, initially building an insulation layer. Subsequently, the winding mechanism tightly adheres to the insulated pipe, spirally winding the insulating material around the outside of the sprayed layer to further enhance the insulation performance.

[0004] However, with the surge in diversified demands in industrial production, the limitations of existing equipment have gradually become apparent. When dealing with the spraying of insulation pipes of different diameters, traditional equipment lacks a flexible pipe diameter adaptive adjustment mechanism, requiring operators to frequently adjust the nozzle position. Each adjustment of the nozzle position is not only time-consuming but may also lead to deviations in the spraying position due to installation errors. To address these issues, we propose a prefabricated insulation pipe spraying and wrapping device. Utility Model Content

[0005] The purpose of this invention is to provide a prefabricated insulation pipe spraying and wrapping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated insulation pipe spraying and winding device, comprising a spraying chamber and support legs installed at the bottom of the spraying chamber, a storage tank installed at the top of the spraying chamber, lifting seats provided on both the left and right sides of the interior of the spraying chamber, spraying head sets installed at opposite ends of the two sets of lifting seats, two sets of guide rods provided on both the left and right sides of the interior wall of the spraying chamber, the two sets of lifting seats forming a sliding connection with the two sets of guide rods, two sets of linear actuators installed on both the left and right sides of the storage tank, the output ends of the two sets of linear actuators being installed at the top center of the lifting seats, a base installed at the bottom of the interior wall of the spraying chamber, a collecting plate slidably connected to the center of the base, a sieve plate slidably connected to the top of the base, sealing plates installed on both the front and rear sides of the spraying chamber via connecting components, and locking components provided on both sides of the front end of the base.

[0007] As an improved technical solution, the connecting assembly includes a frame fixed to the front and rear sides of the top of the spray booth, and a block is installed on the top of each of the two sets of sealing plates. The blocks are embedded inside the frames, and bolts are threaded inside the frames, with the bolts penetrating inside the blocks.

[0008] As an improved technical solution, a through hole is provided in the middle of the two sets of sealing plates.

[0009] As an improved technical solution, the locking assembly includes sleeves fixed on the left and right sides of the front end of the base. Slide rods are installed inside both sets of sleeves. Guide sleeves are slidably connected to the outside of both sets of slide rods. A clamping plate is installed at the top of both sets of guide sleeves. Both sets of clamping plates are located on both sides of the front end of the collecting plate and the sieve plate. Push plates are installed on the outer wall of the front end of both sets of clamping plates. A return spring is wound around the outside of both sets of slide rods.

[0010] As an improved technical solution, the base is provided with grooves corresponding to the collecting plate and the sieve plate.

[0011] As an improved technical solution, a handle is installed at the front end of the collection plate.

[0012] As an improved technical solution, the two ends of the return spring are respectively connected to the inner wall of the sleeve and the outer wall of the guide sleeve, and the guide sleeve is elastically connected to the inner wall of the sleeve through the return spring.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] I. This utility model features liftable lifting seats installed on both sides of the spraying chamber, with spray head assemblies installed at opposite ends of the two sets of lifting seats. When spraying insulation pipes of different sizes is required, the linear actuator can control the height of the lifting seats in real time, allowing the lifting seats to rise and fall along the two sets of guide rods. This maintains a set distance between the spray head assembly and the pipe surface. The storage tank then delivers the insulation coating, which is atomized and sprayed onto the surface of the insulation pipe by the spray head assembly. This eliminates the need for manual adjustment of the nozzle position, improving the adaptability of the device. Furthermore, a pull-out collection plate and sieve plate are installed at the bottom of the spraying chamber, allowing spraying residue to fall onto the sieve plate and recyclable particles to fall into the collection plate, avoiding material waste.

[0015] II. This utility model has two sets of clamping frames installed at the top of the spraying chamber, and bolts are threadedly connected to the clamping frames. When it is necessary to process insulation pipes of different sizes, the corresponding model of sealing plate can be replaced. First, rotate the bolt inside the clamping frame to make the bolt leave the inside of the clamping block, and then push the sealing plate upward to make the sealing plate drive the clamping block away from the inside of the clamping frame, thereby facilitating quick disassembly of the sealing plate and improving the convenience of sealing plate replacement.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] This utility model provides a technical solution: such as Figures 1 to 6 As shown in this embodiment, a prefabricated insulation pipe spraying and winding device includes a spraying chamber 1 and a support leg 2 installed at the bottom of the spraying chamber 1. A storage tank 3 is installed at the top of the spraying chamber 1. Lifting seats 4 are provided on both the left and right sides inside the spraying chamber 1. Spraying head groups 5 are installed at opposite ends of the two sets of lifting seats 4. Two sets of guide rods 6 are provided on both the left and right sides of the inner wall of the spraying chamber 1. The two sets of lifting seats 4 are slidably connected to the two sets of guide rods 6. Two sets of linear actuators 14 are installed on both the left and right sides of the storage tank 3. The output ends of the two sets of linear actuators 14 are installed at the top center of the lifting seats 4. A base 7 is installed at the bottom of the inner wall of the spraying chamber 1. A collecting plate 8 is slidably connected to the middle of the base 7. A sieve plate 9 is slidably connected to the top of the base 7. Sealing plates 10 are installed on both the front and rear sides of the spraying chamber 1 through connecting components. Locking components are provided on both sides of the front end of the base 7.

[0025] By installing lifting seats 4 on both sides inside the spraying chamber 1, and installing spray head groups 5 at opposite ends of the two sets of lifting seats 4, when it is necessary to spray insulation pipes of different sizes, the linear actuator 14 can control the height of the lifting seats 4 in real time, so that the lifting seats 4 can rise and fall along the two sets of guide rods 6, thereby keeping the spray head group 5 at a set distance from the pipe surface. Then, the storage tank 3 delivers the insulation coating, which is atomized and sprayed onto the surface of the insulation pipe by the spray head group 5. This eliminates the need for manual adjustment of the nozzle position, improving the adaptability of the device during use. Furthermore, by installing a pull-out collection plate 8 and a sieve plate 9 at the bottom inside the spraying chamber 1, the spraying residue can fall onto the sieve plate 9, and the recyclable particles can fall into the collection plate 8 through the sieve plate 9, avoiding waste of raw materials.

[0026] In other embodiments, the connecting assembly includes a frame 11 fixed on the front and rear sides of the top of the spray chamber 1, and a block 12 installed on the top of each of the two sets of sealing plates 10. The blocks 12 are embedded inside the frame 11, and bolts 13 are threaded inside the frame 11, with the bolts 13 penetrating inside the blocks 12.

[0027] By installing two sets of clamping frames 11 at the top of the spraying chamber 1 and threading bolts 13 onto the clamping frames 11, when it is necessary to process insulation pipes of different sizes, the corresponding sealing plate 10 can be replaced. First, rotate the bolts 13 inside the clamping frame 11 to make the bolts 13 leave the inside of the clamping block 12, and then push the sealing plate 10 upward, so that the sealing plate 10 drives the clamping block 12 to leave the inside of the clamping frame 11, thereby facilitating the quick disassembly of the sealing plate 10 and improving the convenience of replacing the sealing plate 10.

[0028] In other embodiments, through holes are provided in the middle of the two sets of sealing plates 10;

[0029] With this design, the sealing plate 10 with the corresponding size of the through hole can be replaced according to the actual size of the insulation pipe, so that the insulation pipe can be horizontally inserted into the spraying chamber 1.

[0030] In other embodiments, the locking assembly includes sleeves 15 fixed to the left and right sides of the front end of the base 7. Slide rods 17 are installed inside both sleeves 15. Guide sleeves 18 are slidably connected to the outside of both slide rods 17. Card plates 16 are installed at the top of both guide sleeves 18. Both card plates 16 are located on the front sides of the collecting plate 8 and the sieve plate 9. Push plates 19 are installed on the outer wall of the front end of both card plates 16. Return springs 20 are wound around the outside of both slide rods 17.

[0031] By installing two sets of horizontally movable clamping plates 16 at the front end of the base 7, when it is necessary to remove the collecting plate 8 and the sieve plate 9, the two sets of clamping plates 16 can be pushed to the sides by the push plates 19 outside the two sets of clamping plates 16. This allows the two sets of guide sleeves 18 to drive the clamping plates 16 to move backward along the surfaces of the two sets of slide rods 17, so that the two sets of clamping plates 16 leave the front end of the collecting plate 8 and the sieve plate 9. This releases the two sets of clamping plates 16 from their limiting effect on the collecting plate 8 and the sieve plate 9, making it easier to quickly disassemble the collecting plate 8 and the sieve plate 9, thereby improving the convenience of using the device.

[0032] In other embodiments, the base 7 is provided with grooves corresponding to the collecting plate 8 and the sieve plate 9;

[0033] This design ensures that the collecting plate 8 and the sieve plate 9 can slide smoothly on the base 7, guaranteeing the stability of the equipment during use.

[0034] In other embodiments, a handle is installed at the front end of the collecting plate 8;

[0035] This design allows staff to quickly remove the collection plate 8 by pulling the handle on the outside of the collection plate 8.

[0036] In other embodiments, the two ends of the return spring 20 are respectively connected to the inner wall of the sleeve 15 and the outer wall of the guide sleeve 18, and the guide sleeve 18 is elastically connected to the inner wall of the sleeve 15 through the return spring 20;

[0037] This design allows the return springs 20 outside the two sets of slide rods 17 to continuously apply opposing elastic forces to the two sets of guide sleeves 18, enabling the two sets of guide sleeves 18 to drive the two sets of clamping plates 16 to move in opposite directions to the limit of the sleeve 15.

[0038] This utility model provides a pre-insulated pipe spraying and wrapping device, the specific working principle of which is as follows:

[0039] When using this equipment, the insulation pipe is first passed horizontally through the through hole on the sealing plate 10 by the conveying equipment and enters the spraying chamber 1. Then, the external drive equipment drives the insulation pipe to rotate at a uniform speed. After the insulation pipe enters the spraying chamber 1, the linear drive 14 can control the height of the lifting seat 4 in real time, so that the lifting seat 4 rises and falls along the two sets of guide rods 6, thereby keeping the spraying head group 5 at a set distance from the pipe surface. Then, the storage tank 3 conveys the insulation coating, which is atomized and sprayed onto the surface of the insulation pipe by the spraying head group 5. The spraying residue falls onto the screen plate 9, and the recyclable particles fall into the collection plate 8 through the screen plate 9.

[0040] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
