Description

Technical Field

[0001] The utility model relates to the technical field of HVAC construction, in particular to a device for laying thermal insulation outer skins of pipes used in HVAC projects. Background Art

[0002] In HVAC projects, the correct installation of pipe insulation is crucial for efficient system operation. Insulation not only effectively reduces heat loss from the pipe surface but also significantly improves the efficiency of heat transfer, which is crucial for maintaining energy-efficient heating or air conditioning systems. By reducing energy consumption, insulation helps conserve valuable energy resources while also reducing long-term operating costs, thereby optimizing both economic and environmental benefits.

[0003] In the prior art, thermal insulation materials are usually wrapped around the outside of pipes manually; however, due to the limitations of the actual layout of the pipes, especially for pipes installed at higher positions, construction workers have to take high-risk measures such as climbing or using auxiliary tools such as ladders to carry out construction work; not only is the efficiency low, but it also increases the safety risks of construction, and is prone to falling accidents and physical fatigue caused by long-term high-altitude work. Therefore, the present application provides a pipe insulation skin laying device for HVAC engineering. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the present utility model is to provide a pipe insulation sheath laying device for HVAC engineering, which can lift the pipe insulation sheath from the ground to a high place and perform insulation sheath laying operations on pipes at higher positions. There is no need for construction workers to climb or use ladders for high-altitude operations, thereby reducing construction safety risks and improving the efficiency of laying insulation sheaths.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Provided is a device for laying thermal insulation outer skins for HVAC projects, comprising a lifting frame, a bottom connecting frame and a top connecting frame; the lifting frame is fixedly mounted on the lower side of the bottom connecting frame, and the bottom connecting frame is connected to the top connecting frame via two sets of flexible docking components; the ends of the bottom connecting frame and the top connecting frame are respectively rotatably mounted with stretching arms, and the upper and lower sides of the protective outer skin are respectively provided with bending edges, and the bending edges on both sides are respectively connected to two stretching arms.

[0007] Furthermore, the flexible docking assembly includes a first telescopic drive and a second telescopic drive respectively fixedly mounted on the bottom connecting frame and the top connecting frame, and the magnetic sleeve on the movable end of the first telescopic drive and the magnetic column on the movable end of the second telescopic drive are plugged into each other and connected by magnetic adsorption coupling.

[0009] Furthermore, a heat-insulating layer is provided on the side of the protective outer skin, and the ends of the protective outer skin and the heat-insulating layer are staggered with each other to form a splicing protrusion and splicing groove structure.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The thermal insulation outer skin laying equipment for HVAC engineering projects in the example of the present invention lifts the protective outer skin to the vicinity of the pipe through the lifting frame, and then alternately controls the separation and re-docking of the magnetic sleeves and magnetic columns in the two sets of flexible docking components, so that the protective outer skin fits the outer wall of the pipe, and finally synchronously contracts the first telescopic drive and the second telescopic drive on the two flexible docking components, and moves the lifting frame horizontally, so that the protective outer skin is gradually bent until it is buckled on the outside of the pipe, completing the thermal insulation outer skin laying operation for the higher position pipe.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the utility model are shown in the drawings.

[0031] Example 1:

[0032] like Figure 1-4 As shown, this embodiment provides a pipe insulation skin laying device for HVAC engineering, including a lifting frame 21, a bottom connecting frame 22 and a top connecting frame 25; the lifting frame 21 is fixedly installed on the lower side of the bottom connecting frame 22, and the bottom connecting frame 22 is connected to the top connecting frame 25 through two sets of flexible docking components; the ends of the bottom connecting frame 22 and the top connecting frame 25 are respectively rotatably installed with stretching arms 26, and the upper and lower sides of the protective skin 11 are respectively provided with bending edges, and the bending edges on both sides are respectively connected to the two stretching arms 26.

[0033] like Figure 3-4As shown, the flexible docking assembly includes a first telescopic drive 23 and a second telescopic drive 24 respectively fixedly mounted on the bottom connecting frame 22 and the top connecting frame 25. A magnetic sleeve 231 is fixedly mounted on the movable end of the first telescopic drive 23, and a magnetic column 241 with a polygonal cross-section is fixedly mounted on the movable end of the second telescopic drive 24. The magnetic sleeve 231 and the magnetic column 241 are plugged into each other and connected by magnetic adsorption coupling.

[0034] The magnetic sleeve 231 and the magnetic column 241 both use neodymium iron boron magnets or electromagnets, and the telescopic drive can use a hydraulic cylinder or a linear electric cylinder.

[0035] In this embodiment, the connection method between the bending edge of the side of the protective outer skin 11 and the stretching arm 26 is as follows: an iron sheet is embedded in the bending edge of the side of the protective outer skin 11, and an electromagnet II is installed on the stretching arm 26. The magnetic adsorption coupling connection between the iron sheet and the electromagnet II is utilized to implement the clamping or loosening processing of the protective outer skin 11 by the two stretching arms 26.

[0036] When using the pipe insulation skin laying equipment of this application,

[0037] First, install the protective sheath 11 between the two stretching arms 26, hold the lifting frame 21, and lift the protective sheath 11 to the vicinity of the pipeline 1;

[0038] Afterwards, the magnetic sleeves 231 and magnetic posts 241 in the two sets of flexible docking assemblies are alternately controlled to separate and re-dock, so that the positional relationship between the protective outer skin 11 and the pipe 1 is as follows: Figure 2 The status shown;

[0039] Then, the first telescopic actuator 23 and the second telescopic actuator 24 on the two flexible docking assemblies are retracted synchronously, and the lifting frame 21 is moved horizontally, so that the protective outer skin 11 is gradually bent until it is buckled onto the outside of the pipe 1. During this process, the two stretching arms 26 rotate on their corresponding bottom connecting frame 22 and top connecting frame 25.

[0040] Finally, a pneumatic nail gun is used to nail together the bent edges on both sides of the protective outer skin 11 to complete the laying of the thermal insulation outer skin for the pipe at a higher position. The above operation does not require construction workers to climb or use ladders for high-altitude operations, thereby reducing the safety risks of construction and improving the efficiency of laying the thermal insulation outer skin.

[0041] like Figure 2 As shown, two gripping handles are provided at the bottom of the lifting frame 21, which can be operated synchronously by two operators to reduce the load pressure.

[0042] In this application, the first telescopic actuator 23 and the second telescopic actuator 24 in the two sets of flexible docking assemblies are staggered with each other in the vertical direction. The device relationship is as follows: Figure 3 As shown, this ensures that the protective outer skin 11 will not bend prematurely during the period of alternately controlling the separation and re-docking of the magnetic sleeves 231 and the magnetic pillars 241 in the two sets of flexible docking components.

[0043] Example 2:

[0044] The features that are the same as those in the first embodiment are not described in detail. The differences between the first embodiment and the present embodiment are as follows: Figure 2 and Figure 5 As shown, in this embodiment, the side of the protective outer skin 11 is provided with an insulation layer 12, and the ends of the protective outer skin 11 and the insulation layer 12 are staggered with each other to form a splicing protrusion and splicing groove structure, so that multiple protective outer skins 11 and insulation layers 12 are spliced ​​together in series in sequence, thereby increasing the insulation treatment effect on the HVAC pipe, reducing heat loss on the pipe surface, improving the efficiency of heat energy transmission, saving energy, and reducing long-term operating costs.

[0045] Example 3:

[0046] The features that are the same as those in the first embodiment are not described in detail. The differences between the first embodiment and the present embodiment are as follows: Figure 6-9 As shown, in this embodiment, a rotation driver 32 is fixedly installed on the side of the stretching arm 26 through a bracket 31, and a rotating drum 33 is connected to the output shaft of the rotating driver 32. A stud 34 is inserted and installed in the rotating drum 33, and a threaded hole is provided on the bending edge. The stud 34 is engaged with the threaded hole through a threaded screw.

[0047] The inner side wall of the rotating drum 33 and the end handle of the stud 34 have the same shape and size, and are both polygonal.

[0048] By starting multiple sets of rotation drivers 32, the corresponding rotating drums 33 are driven to rotate, so that the studs 34 are screwed into the threaded holes of the bending edge, and the two stretching arms 26 clamp or loosen the protective outer skin 11. During this process, the studs 34 slide in the rotating drum 33 along their own axis.

[0049] The above-mentioned solution is used to clamp or relax the stretching arm 26, which is more secure than the solution in Example 1. After the protective outer skin 11 is buckled on the outside of the pipe 1, the stud 34 on one side can be directly screwed into the threaded hole on the other side to tighten the protective outer skin 11, thereby improving stability, reducing the need for the use of a pneumatic nail gun, simplifying the equipment required for laying the thermal insulation skin, and improving the efficiency of laying the thermal insulation skin.

[0050] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.

[0051] Except for the technical features described in the specification, the remaining technical features are known technologies to those skilled in the art. In order to highlight the innovative features of the present utility model, the remaining technical features will not be described in detail here.
