Description

Technical Field

[0001] The utility model relates to the technical field of foam pipe ring cutting, in particular to a foam pipe ring cutting tool. Background Art

[0002] Most of the current heat pipe insulation uses various insulation materials. Including foam, polyurethane foam, inorganic materials, such as glass wool, rock wool, among which inorganic materials have relatively low cost and good weather resistance. But they cause greater environmental pollution and are very bad for the human body. Foam and polyurethane foam are easy to use, but have low weather resistance. However, for heat pipe systems that need to be repaired every few years, the first two materials are better used in safe areas with non-flammable and explosive warnings and high temperatures (pipe temperatures exceeding 100 degrees). However, foam materials are molding materials, and the pipes of the heat pipe system are thick and thin. If multiple foam materials are used for multiple pipes, then there will be a lot of different types of foam pipes that need to be purchased, and a large number of different types of foam pipes need to be stored.

[0003] In most commercial and office buildings, small pipes are mostly used. Moreover, the pipes are dense, and it is time-consuming and labor-intensive to use individual coatings, and the insulation effect is poor. If polyurethane foam is used for sealing and insulation, if some pipes need to be repaired, they can only be cleaned up in a time-consuming manner. There are also handheld hot cutters, but the use of such tools depends entirely on the proficiency of the workers. It is not conducive to the use of novices. Therefore, in view of the above shortcomings, a foam pipe ring cutting tool is proposed to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 - Figure 3 and Figure 7 The utility model provides an embodiment: a foam pipe ring cutting tool, including a foam plate 1, a fixing frame 3 and a balance board 6, a walking assembly is arranged outside the fixing frame 3, the walking assembly includes a handle 4, the left side of the handle 4 is fixedly connected to the right side of the fixing frame 3, the handle 4 controls the direction of the pipeline line, a guide wheel 5 is arranged inside the fixing frame 3, the guide wheel 5 is used to prevent the cutting groove from deflecting to both sides, a support plate 7 is fixedly connected to the front and rear sides of the top of the balance board 6, a fixed shaft 8 is fixedly connected to the inside of the two support plates 7, the left side of the fixing frame 3 is fixedly connected to the outside of the fixed shaft 8, and the front and rear sides of the fixed shaft 8 are fixedly connected to walking wheels 9;

[0028] Reference Figure 2 - Figure 4, the fixed position of the guide wheel 5 is slightly backward, and the axis position is the same as the vertical position of the nickel strip 15. This is to lift the handle 4 when turning when cutting the foam, so that the front walking wheel 9 is raised, and then it will not deviate when rotating along the pipeline direction. The top of the balance plate 6 is fixedly connected to the connecting plate 10, and the outer left side of the connecting plate 10 is fixedly connected to two conductive plates 11, which are used for conducting electricity. A wiring peephole 12 is provided on the outer left side of the connecting plate 10. The wiring peephole 12 is used to observe the pre-drawn wiring to prevent deviation. A plurality of plug-in slots 13 are provided inside the two conductive plates 11, and the fixed shaft 8 is arranged vertically to the position of the plug-in slot 13. The internal thread of the connecting plate 10 is connected with a bolt 14, and the outer bottom side of the bolt 14 is threadedly connected to the inside of the balance plate 6. Nickel strips 15 are arranged inside the two plug-in slots 13, and the outside of the nickel strip 15 is arranged inside the plug-in slot 13. The nickel strip 15 is used for electrothermal cutting of foam, and the folded shape on it is to be stuck on it after being inserted into the fixing hole of the nickel strip 15 fixing piece without falling off;

[0029] Reference Figure 4 - Figure 6 The outside of the conductive plate 11 is fixedly connected with a wire 16, which is used to conduct current. The outside of the wire 16 is fixedly connected with a transformer 17, which converts 220V AC power into low-voltage DC power, and melts the foam board by electrically heating the nickel strip 15. A foam board 2 2 is arranged on the top of the foam board 1, and a plurality of hot and cold pipes 18 are arranged on the top of the foam board 1, and the outside of the hot and cold pipes 18 is arranged at the bottom of the foam board 2 2.

[0030] Working principle: When the construction workers insulate the installed pipes, they first select foam sheets of different thicknesses according to the height of the pipes and the distance between the pipes and the top, and then brush a small amount of carbon powder or ink on the top and bottom of the pipes. Other adhesives can also be used. After brushing, two foam sheets of the same size are vertically pressed against the pipes brushed with carbon powder, and then taken down. At this time, the foam will leave traces of the direction of the pipes. If the construction workers are not skilled workers, they need to take nickel strips 15 of different sizes to compare with each pipe. Then insert the appropriate nickel strip 15 into the symmetrical plug-in slot 13 of the conductive plate 11, and then connect 16 to the 220V power supply and turn on the switch. At this time, the low-voltage direct current output by the transformer 17 will be transmitted to the conductive plate 11 on the connecting plate 10 through the wire 16 and transmitted to the nickel strip 15, so that it is heated. The construction worker holds the handle 4 and performs hot-melt cutting along the carbon powder trace on the plate. If the worker is not very skilled, he needs to calibrate the direction through the wiring peephole 12 and the handle 4 during cutting, and continue cutting along the trace. When the pipeline trace is bent, the worker lifts the handle 4. Due to the specific position design of the balance board 6, the nickel strip 15 will not deviate when the handle 4 is lifted. At this time, the worker can deflect and cut along the trace. When returning to the long straight pipeline, the handle 4 can be put down again so that the front walking wheel 9 is connected to the foam plate 1, and the handle 4 is aligned with the far end of the straight trace, so that the semicircular groove of the pipeline can be accurately cut. When it is necessary to replace the nickel strip 15 of different pipe diameters, the worker first disconnects the transformer 17, and then waits for the nickel strip 15 to cool down naturally, or uses a wet cloth to cool it down. The thinner and narrower the nickel strip 15 is, the less heat capacity it has, and the faster it cools down. It will generally drop to room temperature in a few seconds to more than 20 seconds according to the local temperature. At this time, the worker can pull the nickel strip 15 down by hand and replace it with another nickel strip 15. When the foam sheet 1 is processed, the foam sheet 2 can be processed. When both are completed, they can be installed. Since it is a pipe groove cut in accordance with the shape, it can be installed very accurately. The two pieces of foam can be fixed by bundling, or by drilling holes with a drill bit and fixing them with screws at a place far away from the pipe. Since it is an overall foam wrap, this method has a much better thermal insulation effect than a single pipe, and is of great significance for energy conservation and emission reduction.
