Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pipeline protection equipment, and in particular relates to a construction device for applying paste-like coatings to pipelines. Background Technology
[0002] Currently, the application of paste-like thermal insulation coatings for industrial pipelines is commonly done using tools such as trowels and flexible stainless steel scrapers. However, because maintaining a consistent angle and thickness during coating application requires highly skilled workers, it is very dependent on their experience. Controlling the angle and thickness relies heavily on the worker's expertise, making it difficult for novices or non-professionals to operate consistently. This can easily lead to uneven coating thickness, missed areas, and consequently, compromised coating performance. Furthermore, manual application is labor-intensive, inefficient, and makes it difficult to quantify coating usage. Localized application that is too thin or too thick not only increases the risk of rework but also results in material waste.
[0003] To address the aforementioned issues, the construction tools have been upgraded. This reduces the difficulty of manual operation and ensures coating thickness and uniformity. It can significantly improve the application quality of paste-like thermal insulation coatings, reduce reliance on the technical experience of construction personnel, and achieve a dual improvement in coating performance and construction efficiency.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example
[0032] See appendix Figure 1 , 2As shown in Figures 3, 4, and 5, a construction device for applying paste-like coating to pipelines includes a hollow storage cylinder 1. Sealing plates 2 are fixedly connected to the openings at both ends of the storage cylinder 1, forming a coating cavity 11 with the storage cylinder 1 and the two sealing plates 2. Guide holes 21 and discharge holes 22 are respectively provided on the two sealing plates 2, and are coaxially arranged with the storage cylinder 1. A discharge cylinder 3 is fixedly connected coaxially with the discharge hole 22 on the sealing plate where the discharge hole 22 is located, and the storage cylinder 1 communicates with the inner cavity of the discharge cylinder 3 through the discharge hole 22.
[0033] The inner diameter of the guide hole 21 is matched with the outer diameter of the industrial pipe 5. That is, the inner diameter of the guide hole 21 can be slightly larger than the inner diameter of the industrial pipe 5, so that when the industrial pipe 5 passes through the guide hole 21, it can achieve relative sliding between the industrial pipe 5 and the storage cylinder 1, and can also prevent the paste coating from overflowing from the gap between the guide hole 21 and the outer circumference of the industrial pipe 5 to a certain extent.
[0034] The inner diameter of the discharge hole 22 can be the same as the inner diameter of the storage cylinder 1. The inner diameter of the discharge cylinder 3 is larger than the outer diameter of the industrial pipeline 5, and the specific inner diameter of the discharge cylinder 3 can be determined according to the thickness of the paste coating applied on the industrial pipeline 5. That is, a coating cavity 31 is formed between the inner wall of the discharge cylinder 3 and the outer circumference of the industrial pipeline 5.
[0035] A guide is provided on the inner wall of the storage cylinder 1, with one end of the guide away from the inner wall of the storage cylinder 1 abutting against the outer circumference of the industrial pipeline 5. The function of the guide is to support the construction device on the industrial pipeline 5 and guide it when the construction device slides relative to the industrial pipeline 5. The guide can have various structures; in this embodiment, the guide is a fixed rod 4 with one end fixedly connected to the inner wall of the storage cylinder 1 and the other end abutting against the outer circumference of the industrial pipeline 5. This guide has a simple structure, and by reducing the contact area between the fixed rod 4 and the industrial pipeline 5, it facilitates the sliding of the construction device on the industrial pipeline 5. Specifically, four fixed rods 4 are evenly distributed along the circumference of the storage cylinder 1, and the ends that abut against the industrial pipeline 5 are rounded.
[0036] A filling port 12 is provided on the storage cylinder 1. The filling port 12 is connected to the paint dispensing assembly (not shown in the figure) through a connecting pipe (not shown in the figure). The paint dispensing assembly includes an existing pressurizing device and a storage tank. The pressurizing device injects the paste-like paint in the storage tank into the paint chamber 11 through the connecting pipe and the filling port 12.
[0037] To facilitate the movement of this construction device, a handle 13 is fixedly connected to the outer side of the storage cylinder 1.
[0038] In actual use, the above-mentioned construction device is fitted onto the industrial pipeline 5. The paint dispensing component continuously injects the paste paint into the paint chamber 11. The construction device is pulled manually or by machine, and the paste paint overflows from the paint chamber 11 and the coating chamber 31, thereby uniformly coating the paste paint onto the industrial pipeline 5. The gap between the inner wall of the discharge cylinder 3 and the industrial pipeline 5 is the coating thickness.
[0039] The above-mentioned construction device can be constructed of metal materials, and the various components can be fixed by welding. Of course, other materials, such as plastic, can also be used. Since the above-mentioned construction device is an integral structure, when the industrial pipeline 5 has already been installed or it is not possible to fit this construction device from both ends, it is necessary to design this construction device as a split structure, as shown below.
[0040] The storage cylinder 1 includes an upper storage cylinder 14 and a lower storage cylinder 15. The sealing plate 2 includes an upper sealing plate 23 and a lower sealing plate 24. The upper storage cylinder 14, the lower storage cylinder 15, the upper sealing plate 23, and the lower sealing plate 24 can be mutually enclosed to form a coating cavity 11. The discharge cylinder 3 includes an upper discharge cylinder 32 and a lower discharge cylinder 33 that can be connected to each other to enclose a coating cavity 31. The upper sealing plate 23 and the lower sealing plate 24 are respectively fixedly connected to the upper discharge cylinder 32 and the lower discharge cylinder 33. Four fixing rods 4 can be evenly and fixedly installed on the inner walls of the upper storage cylinder 14 and the lower storage cylinder 15.
[0041] The upper storage cylinder 14 and the lower storage cylinder 15 are detachably connected by fasteners. The fasteners can have various structures, as long as they can securely connect and detach the upper and lower storage cylinders 14 and 15. In this embodiment, to facilitate the fixing and disassembly of the upper and lower storage cylinders 14 and 15, the fastener is a spring-loaded latch assembly 6 fixedly connected to the upper sealing plate 23 and the lower sealing plate 24. The spring-loaded latch assembly 6 can be an existing padlock latch structure, where the lock body and hook body are respectively fixedly installed on the upper sealing plate 23 and the lower sealing plate 24.
[0042] In actual use, the two halves of the split-type construction device are first secured to the industrial pipeline 5: the upper sealing plate 23, the upper storage cylinder 14, and the upper discharge cylinder 32. Then, the other half—the lower sealing plate 24, the lower storage cylinder 15, and the lower discharge cylinder 33—are correspondingly secured to the industrial pipeline 5. The storage cylinder 1 is then secured to the industrial pipeline 5 using the spring-loaded fastener assembly 6. Subsequently, the paint dispensing assembly continuously injects paste-like paint into the paint chamber 11. The construction device is manually or mechanically pulled, and the paste-like paint overflows from the paint chamber 11 and the coating chamber 31, thus uniformly coating the industrial pipeline 5. The gap between the inner wall of the discharge cylinder 3 and the industrial pipeline 5 is the coating thickness.
[0043] Furthermore, when different thicknesses of coating need to be applied to the industrial pipeline 5, an adjusting sleeve 7 can be fixedly embedded in the inner cavity of the discharge cylinder 3. Specifically, the adjusting sleeve 7 is detachably and fixedly embedded in the inner wall of the discharge cylinder 3 and the discharge hole 22. To facilitate the fitting of the adjusting sleeve 7 onto the industrial pipeline 5, the adjusting sleeve 7 includes an upper adjusting sleeve 71 and a lower adjusting sleeve 72, respectively corresponding to the upper discharge cylinder 32 and the lower discharge cylinder 33. When the storage cylinder 1 is fixed by the spring latch assembly 6, the adjusting sleeve 7 can also be fixedly embedded in the discharge cylinder 3. At this time, the gap between the inner wall of the adjusting sleeve 7 and the industrial pipeline 5 is the coating thickness.
[0044] In addition, to prevent the adjusting sleeve 7 from sliding out of the discharge cylinder 3 when the construction device is pulled, a retaining ring 73 is formed by extending one end of the adjusting sleeve 7 outward. The retaining ring 73 is set inside the sealing plate 2 on the side where the discharge cylinder 3 is fixedly installed, and the outer diameter of the retaining ring 73 is larger than the inner diameter of the discharge hole 22.
[0045] Therefore, when the coating thickness needs to be adjusted, adjustment sleeves 7 of different thicknesses can be placed inside the discharge cylinder 3. In actual use of this split-type construction device with adjustable coating thickness, the upper sealing plate 23, upper storage cylinder 14, upper discharge cylinder 32, and upper adjustment sleeve 71 are first secured to the industrial pipeline 5. Then, the other half of the lower sealing plate 24, lower storage cylinder 15, lower discharge cylinder 33, and lower adjustment sleeve 72 are correspondingly secured to the industrial pipeline 5. Then, the storage cylinder 1 is secured to the industrial pipeline 5 by the spring-loaded fastener assembly 6. Afterward, the paint dispensing assembly continuously injects the paste paint into the paint chamber 11. The construction device is pulled manually or by machine, and the paste paint overflows from the paint chamber 11 and the coating chamber 31, thereby uniformly coating the paste paint onto the industrial pipeline 5. The gap between the inner wall of the adjustment sleeve 7 and the industrial pipeline 5 is the coating thickness.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
