Description

Technical Field

[0001] The invention belongs to the technical field of pipeline supports, and in particular relates to a foaming support for manufacturing pipeline surface insulating materials. Background Art

[0002] Outer insulation is a key protection technology in pipeline systems. By wrapping or installing specific insulating materials or components on the outside of the pipeline, it blocks the current path, contact with corrosive media or energy transfer between the pipeline and the external environment, thereby protecting the integrity of the pipeline, extending its service life, and improving system safety. Its core goal is to achieve electrical isolation, anti-corrosion protection and structural stability, while taking into account auxiliary functions (such as thermal insulation, sound insulation, etc.).

[0003] In the actual construction process, prefabricated insulation material blocks are currently used and transported to the construction site for on-site bonding. However, on-site bonding has the following problems: on-site bonding will result in bonding seams, which are prone to cold leakage over time. Using prefabricated insulation material blocks for bonding, it is impossible to intuitively control the overall thickness of the pipeline after bonding. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problems of cold leakage caused by bonding seams and the thickness of the entire pipeline after bonding, and to provide a foaming bracket for foaming insulating materials on the pipeline surface, comprising a pipeline and a tubular shell, characterized in that the two ends of the tubular shell are mounted on the outer periphery of the pipeline through at least a pair of oppositely arranged foaming brackets, and a foaming space is formed between the pipeline and the tubular shell, and the outer periphery of the tubular shell is provided with a material injection hole connected to the foaming space;

[0005] The foaming bracket includes a support seat that can be detachably fixed to the outer periphery of the pipeline, and the support seat is movably connected to a support rod. The side edge of the support rod facing the tubular shell is concave with a placement groove, and a threaded hole is penetrated at the top of the placement groove. The two ends of the tubular shell are placed in the opposite placement grooves and are screwed and fixed by bolts.

[0006] Furthermore, when a plurality of foaming brackets are provided at one end of the tubular housing, two adjacent foaming brackets are connected and fixed to each other via a connecting piece;

[0007] The four corners at the bottom of the support seat of each foaming bracket are provided with through channels with pipeline lengths opposite to the two corners, each through hole channel is inserted with a fixing rod, and both ends of the connecting piece are provided with fixing holes. Two adjacent foaming brackets are fixed by connecting the two ends of the connecting piece to the two fixing rods respectively.

[0008] Furthermore, a support groove is concave in the upper surface of the support seat, and rotation holes are arranged on the groove walls on both sides of the support groove. A rotation shaft is integrally provided at the bottom end of the support rod, and the support rod is rotatably connected to the support seat through the rotation shaft.

[0009] Furthermore, the side walls on opposite sides of the support seat are provided with limiting holes, and the support seat is detachably fixed to the outer periphery of the pipeline through the limiting holes by means of elastic members.

[0010] Furthermore, the limiting hole is configured as a hole groove communicating with the upper end surface of the side wall of the support seat, the elastic member is an elastic rope, and the support seat is detachably fixed to the outer periphery of the pipeline through the elastic rope.

[0011] Furthermore, when there are multiple foaming brackets at one end of the tubular shell, the multiple foaming brackets are arranged at equal intervals on the outer periphery of the pipeline, and the number of foaming brackets at both ends of the tubular shell is the same and corresponds one to one.

[0012] Furthermore, one end of the bolt extending into the prevention groove is threadedly connected with an abutment block, which protrudes toward the outer circumference of one end of the bottom of the placement groove, and the end of the tubular shell is fixed to the bottom of the placement groove through the abutment block.

[0013] Furthermore, after foaming, the insulating material is formed inside the foaming space, and the thickness of the insulating material is determined by the length of the support rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in:

[0015] 1. The present invention injects foaming material into the outer layer of the pipeline through the injection hole preset in the tubular shell. The foaming material is tightly combined with the pipeline, thereby avoiding the generation of gaps and the penetration of corrosive media and cold leakage caused by the gaps.

[0016] 2. The foamed insulating material of the present invention is formed inside the foaming space, and the height of the insulating internal space is determined by the length of the support rod. Therefore, the thickness of the foamed insulating material can be directly controlled at the construction site by setting the length of the support rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be described in more detail with reference to a schematic diagram of a foaming bracket for on-site foaming of insulating materials on the surface of a pipeline according to the present invention, wherein a preferred embodiment of the present invention is shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0022] like Figure 1 As shown, a foaming bracket 3 for foaming insulating material on the pipeline surface is used to set up the shell on the outer periphery of the pipeline 1. The shell is a tubular shell 2, and the foaming bracket 3 is fixed on the outer periphery of the pipeline 1. The two ends of the tubular shell 2 are set on the outer layer of the pipeline 1 through two foaming brackets 3 respectively arranged opposite to each other, and a foaming space for foaming insulating material is formed between the inner layer of the tubular shell 2 and the outer layer of the pipeline 1. The tubular shell 2, which serves as an auxiliary tool, is provided with a plurality of injection holes 21 arranged at equal intervals on its outer periphery for injecting foaming material into the foaming space.

[0023] The foaming bracket 3 of the present invention is used to set up the tubular housing 2 on the periphery of the pipeline 1. As an embodiment, the present invention only provides a figure (such as a figure) in which the foaming bracket 3 is set at one end of the tubular housing 2. Figure 1 As shown in the figure, however, as a setting condition, a foaming bracket 3 is also provided at the other end of the tubular housing 2, and the two foaming brackets 3 are arranged opposite to each other. Similarly, not only one foaming bracket 3 can be provided at one end of the tubular housing 2, but also multiple foaming brackets 3 can be provided, and multiple foaming brackets 3 are arranged at equal intervals on the outer periphery of the pipeline 1 until they are connected into a circle. The number of foaming brackets 3 at both ends of the tubular housing 2 is the same, and they correspond one to one, and the structural settings of the multiple foaming brackets 3 are the same.

[0024] refer to Figure 2 The foaming bracket 3 includes a support seat 31 which is detachably fixed to the outer periphery of the pipeline 1, and a support rod 33 which is rotatably fixed on the support seat 31. The side edge of the support rod 33 facing the tubular shell 2 is concave with a placement groove 34 for placing the end of the pipeline 1. A threaded hole is penetrated through the top of the placement groove 34, and a bolt 35 is connected to the threaded hole. The foaming bracket 3 is tightened with the bolt 35 to the end of the tubular shell 2 placed on the bottom surface of the placement groove 34, so that the tubular shell 2 is erected on the outer periphery of the pipeline 1.

[0025] Specifically, the support seat 31 is fixed to the outer periphery of the pipeline 1 by an elastic member 4, i.e., a rubber band. The upper surface of the support seat 31 is concave with a support, and the tops of the groove walls on both sides of the support groove are relatively concave with limit holes 36. The limit holes 36 are set as hole grooves. The rubber band sleeved on the outer periphery of the pipeline 1 is stretched into the hole groove to achieve fixation based on the tightening force of the rubber band, and the support seat 31 is firmly fixed to the outer periphery of the pipeline 1. This fixation is detachable, and the support seat 31 can be removed by manually pulling the rubber band.

[0026] The concave support groove of the support seat 31 is used to place the bottom end of the support rod 33. The bottom end of the support rod 33 has a rotating shaft 32 extending to both ends. Corresponding rotating holes are provided on the opposite sides of the support groove. By inserting the rotating shaft 32 into the rotating hole, the support rod 33 can be rotated based on the rotating shaft 32.

[0027] In order to prevent the support rod 33 from rotating in a direction away from the tubular shell 2, we set the rotating hole 32 closer to the tubular shell 2 than the limiting hole 36. Therefore, when the rubber band is stretched and put into the limiting hole 36, the rubber band is located on the side of the support rod 33 away from the tubular shell 2, limiting the rotation of the support rod 33 in this direction.

[0028] We also improve the screw-tightening bolt 35, such as Figure 3 As shown, at one end of the bolt 35 extending into the placement groove 34, the thread 35 is connected with an abutment block 39, which is used to increase the contact area between the bolt 35 and the tubular housing 2 and increase the tightness of the screwing. Specifically, the abutment block 39 is protruded toward the outer circumference of the tubular housing 2 at one end thereof, forming a protruding flat cylindrical convex block, and the bottom surface of the convex block is much larger than the area of ​​the end of the bolt 35.

[0029] When the number of the foaming brackets 3 at one end of the tubular housing 2 is set to be multiple, even connected to form a circle, we connect two adjacent foaming brackets 3 by setting a connecting piece 38 at the bottom of the support seat 31. Specifically, fixed through-channels are set at two corners of the four corners of the bottom of each support seat 31 facing the length direction of the pipeline, and each through-channel is inserted with a fixing rod 37. A connecting piece 38 is fixed to each end of each fixing rod 37, and one end of the connecting piece 38 is fixed to the fixing rod 37, and the other end is fixed to the fixing rod of the support seat in the adjacent foaming bracket, so as to realize the connection and fixation between the two adjacent foaming brackets 3.

[0030] The tubular housing 2 of the present invention is configured as a stainless steel housing, the length of which depends on the length of the outer insulating material of the one-time-made pipeline 1, and the length is preferably limited to within 0.5 m.

[0031] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
