With the expansion of the coverage area of ​​the heating network, my country's main measures are centralized heating, which is to use centralized heat sources to supply production and life, heating and centralized heating to factories and civil buildings in a larger area. It has a history of nearly 100 years. Because it has the advantages of saving fuel and reducing urban pollution, it has developed rapidly. More than 20 countries in the world have adopted centralized heating. In the urban centralized heating system, hot water is used as the intermediate medium for transmitting heat. The transportation pipeline is an important carrier and the most important infrastructure. It plays the role of transmission in the long-distance heating pipeline heat transmission. With the acceleration of urbanization, the urban heating area continues to expand, and the heating network is rapidly expanding. There are three commonly used methods for laying heating pipelines: overhead laying, direct burial laying and trench laying. With the development of heating pipeline technology, the upper and lower settings of the water supply and return double pipelines or the parallel water pipelines are gradually adopted. Therefore, this double pipe must be fixed with an external protective work fixed bracket to play a role in fixing and positioning the pipeline.

[0003] At present, the fixed brackets of long-distance heating pipelines are prone to deformation and instability. In humid environments, the brackets are prone to corrosion. For fixed brackets with a single structure, when the pipeline is dismantled and replaced for installation, the fixed brackets must be destroyed, disassembled and replaced with new ones, resulting in unnecessary waste of resources. In order to meet the new requirements for fixed brackets for pipelines, the following technical problems are now solved: the existing fixed brackets for long-distance heat transmission pipelines are single, unstable and easy to damage.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same technical meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0031] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. It should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0032] like Figures 1 to 3 The embodiment shown, Figure 1 This is a structural diagram of a steel heating pipe support for a detachable long-distance heat transmission pipeline of the present invention. Figure 2 It is a structural diagram of a rectangular nut chuck. Figure 3 This is a schematic diagram of the direction of the tooth buckle. Figure 1 , Figure 2 and Figure 3 The present invention will be described in detail.

[0033] The present invention provides an insulated pipe fixing bracket, which can solve the problem that the existing long-distance heat transfer pipe is fixed with a single, unstable and easily damaged fixing bracket when the pipe is pre-buried. The insulated pipe fixing bracket of the present invention is easy to install and implement when laying underground pipes, has strong stability, can more effectively protect the pipe structure, and is convenient for construction personnel to install.

[0034] Specifically, if Figure 1 As shown, the insulation pipe fixing bracket includes two reinforcing plates 1 arranged opposite to each other up and down, the material of the reinforcing plates 1 includes but is not limited to a plate made of steel material, and the two reinforcing plates 1 are arranged opposite to each other, and they are connected by at least two anchor rods 10, and a pipe sleeve 6 is fixedly installed on the opposite sides of the two reinforcing plates 1, and the two pipe sleeves 6 are connected by a sliding buckle 4, and the insulation pipe is installed in the pipe sleeve 6.

[0035] In one or more feasible embodiments, the fixing method of the above-mentioned reinforcing plate 1 and the pipe sleeve 6 includes but is not limited to integrally forming the reinforcing plate 1 and the pipe sleeve 6, or the reinforcing plate 1 is formed separately and the pipe sleeve 6 is formed separately. A pipe sleeve bracket can be provided on the pipe sleeve 6, and then connected to the reinforcing plate 1 through the pipe sleeve bracket. The connection method can be selected by providing holes on both the pipe sleeve bracket and the reinforcing plate 1, and connecting the pipe sleeve 6 to the reinforcing plate 1 together by a fixing member (such as a bolt assembly) passing through the hole.

[0036] Furthermore, in some embodiments, an elastic member 11 is installed inside the pipe sleeve 6, and the elastic member 11 is used to support the insulated pipe. The selection of the elastic member 11 includes but is not limited to existing wave-shaped plastic air cushions or rubber cushions and other support members made of elastic materials, which are used to support the insulated pipe so as to reduce the buffering of the insulated pipe when there are large vibrations in the road section, especially when the road section shakes caused by earthquakes; at the same time, because the material of the elastic member itself has a certain thermal insulation effect, it can play a partial insulation role for the insulated pipe.

[0037] In one or more feasible embodiments, the anchor rod 10 used to connect between the two reinforcing plates 1 is an anchor rod with threads at both ends, and the threaded portion at the end of the anchor rod 10 can be screwed into a nut for nut fixation. That is, after the anchor rod 10 passes through the reserved holes on the two reinforcing plates 1, the protruding portion at the end can be fixed by the nut, thereby fixing the two reinforcing plates 1.

[0038] The number of anchor rods 10 used for fixing between the two reinforcing plates 1 is at least two, so as to ensure the stability of the fixing. Of course, other numbers of anchor rods may also be used, which is not limited by the present invention.

[0039] Furthermore, a nut chuck 7 is fixed to the outer side of the reinforcing plate 1 provided at the lower part (i.e., the lower part of the reinforcing plate 1) for fixing the nut to prevent the nut from loosening or even falling off due to vibration caused by water flow or other reasons during the operation of the pipeline. The shape of the nut chuck 7 can be the same as the shape of the reinforcing plate 1, or it can be different from the shape of the reinforcing plate 1. In some embodiments, the reinforcing plate 1 is rectangular, and the nut chuck 7 can be the same rectangular shape as the reinforcing plate 1. Nut fixing holes are provided on the nut chuck 7, and the number of nut fixing holes is the same as the number of anchor rods 10. The shape of the nut fixing holes is the same as the shape of the nut, and is slightly larger than the nut, so as to facilitate sleeves on the nut. In order to fix the nut with the nut chuck 7 and prevent the nut from loosening, the nut is preferably a non-circular nut, such as a hexagonal nut, and the shape on the nut chuck 7 is the same as the shape of the nut. That is, the nut chuck 7 has a nut fixing hole that matches the shape of the nut at the end of the anchor rod 10, so that the nut chuck 7 can be installed on the reinforcing plate 1 and put on the nut. Since the threaded product may be stripped and fall off after a long time of use in a vibrating environment after being tightened, the nut chuck provided in the present invention fixes the nut. When the nut is fixed, the rectangular strip-shaped nut chuck locks the upper and lower pairs of nuts respectively. Under the premise that the nut is a non-circular nut, it can prevent the nut from rotating and then loosening, and will not fall off due to soil environment fluctuations.

[0040] In one or more feasible embodiments, the upper part of the upper reinforcement plate 1 may also be fixed with a nut chuck 7, and the nut chuck 7 is generally selected to have the same shape as the nut chuck 7 provided at the lower part. Generally speaking, the purpose of preventing the nut from falling off of the present invention can be achieved by only fixing the nut chuck on the lower reinforcement plate; however, in order to further optimize the fixation, the upper part of the upper reinforcement plate 1 may also be provided with a nut chuck 7, and the installation and fixing method of the nut chuck 7 is the same as the installation and fixing method of the lower reinforcement plate 1.

[0041] In order to ensure the fixed connection between the nut chuck 7 and the reinforcing plate 1 and to ensure the fixation of the nut, the present invention also has a fixing member for fixing the nut chuck 7 and the reinforcing plate 1, which includes but is not limited to the existing screws passing through the reinforcing plate 1 and the nut chuck 7, and the screws are fixed with anti-slip nuts; or a rope-type fixing member for tying and fixing the nut chuck 7 and the reinforcing plate 1 can also be used, for example, by fixing with a steel wire rope and a lock buckle matched with the steel wire rope; or an existing self-locking nylon tie can be used as a fixing member. The present invention does not limit it, and it can be fixed by a suitable existing device selected according to the specific implementation needs.

[0042] Furthermore, the sliding buckle arranged between the pipe sleeves 6 of the two reinforcing plates 1 arranged opposite to each other up and down of the present invention includes two elastic plates respectively arranged on the two pipe sleeves 6, the four elastic plates are adjacent to each other, and the two adjacent elastic plates belong to different pipe sleeves 6, and the adjacent elastic plates have teeth on their opposite surfaces.

[0043] The specific description is as follows: the elastic plate can be selected as an elastic steel plate, one side of the steel plate has a toothed tooth buckle, and the tooth buckles of two adjacent steel plates are in opposite directions, so that the tooth buckles of the two steel plates are buckled together and not easy to slip off, and the external force for the tooth buckles of the two adjacent steel plates is that the steel plates themselves have a certain degree of bendability and deformation resistance, that is, the two adjacent steel plates are in an adjacent state and in a mutually squeezed state under normal conditions, and the mutual squeeze state can buckle the tooth buckles together. When one side of the tooth buckles of the two steel plates are in contact and contact under the action of the steel plates themselves, because the tooth buckles on the steel plate connected to the lower pipe sleeve are designed to be downward, and the tooth buckles on the steel plate set on the upper pipe sleeve are upward, when the upper reinforcing plate 1 is pressed downward, the tooth buckles of the two contacting steel plates slide alternately and do not affect their downward movement, and can make the tooth buckles of the two steel plates buckle together under the action of the squeezing force between the two steel plates, thereby connecting the two pipe sleeves, such as Figure 3 If the entire bracket needs to be disassembled, the contacting steel plates are moved downward for a short distance under the action of external force, and then the steel plates are separated in opposite directions, so that the buckled teeth can be disassembled.

[0044] After installing the sliding buckle 4, the two independent pipe sleeves 6 can be connected together or disassembled, that is, the steel heating pipe bracket is detachable and divided into two parts. There are pipe sleeves 6 on the upper and lower load-bearing reinforcement plates 1 for fastening the pipelines. When the upper and lower connecting parts are assembled, the sliding buckle 4 is used to tighten the mutually embedded parts of the pipe sleeves.

[0045] In specific applications, the arrangement of the mutually interlocking pipe sleeves 6 can be applied to upper supply and lower return heat transfer pipelines, and can also be applied to side-by-side double pipeline arrangements.

[0046] In one or more feasible embodiments, a spring 13 is sleeved on the anchor rod 10 between the two reinforcing plates 1; after the spring 13 is installed, the upper reinforcing plate 1 is pressed down, so that the spring 13 is in a compressed state with a certain amount of compression, which is generally not the full compression amount. The spring 13 can elastically support the two reinforcing plates 1. When the pipeline fixing bracket moves under the action of external force, after the pipeline bracket is fixed and installed, the lower reinforcing plate is fixed and everything is ready, the pipeline will be filled with sand and gravel at the same height as the upper plate to start reinforcing the upper plate. The tightening can compress the spring and tightly squeeze the sand and gravel between the upper and lower reinforcing plates of the fixed bracket to keep the surrounding environment of the pipeline stable, even if the road collapses, it can maintain its shape. The compression of the spring can prevent fluctuations caused by earthquakes and increase the toughness of the fixed bracket, thereby compressing the spring and tightly squeezing the sand and gravel between the upper and lower reinforcing plates of the fixed bracket to keep the surrounding environment of the pipeline stable, even if the road collapses, it can maintain its shape. The compression of the spring can prevent fluctuations caused by earthquakes and increase the toughness of the fixed bracket.

[0047] Furthermore, the present invention also provides a method for installing a thermal insulation pipe fixing bracket, comprising the following steps:

[0048] Step 1: First, prepare two reinforcement plates, then install two anchor rods 10 on the lower reinforcement plate 1, and install nuts at the lower ends of the anchor rods 10;

[0049] Step 2: Install the nut chuck 7 at the lower part of the lower reinforcing plate 1, so that the nut screwed to the end of the anchor rod is located in the nut fixing hole on the nut chuck 7, and fix the lower reinforcing plate 1 and the nut chuck 7 together through a fixing piece;

[0050] Step 3: Place the lower reinforcing plate 1 with the anchor rod 10, nut, and nut chuck 7 installed at the installation position;

[0051] Step 4: Put the spring 13 on the two anchor rods 10;

[0052] Step 5: Install the upper reinforcing plate 1 so that the teeth of the elastic plates facing each other on the two sleeves 6 are fastened and grasped firmly;

[0053] Step 6: Fill the soil blocks and gravel so that the height of the filled soil blocks and gravel is the same height as or lower than the upper reinforcement plate 1, and tighten the anchor nuts on the upper reinforcement plate 1 to tighten it;

[0054] Step 7: Continue filling with soil, sand and gravel until the filling is completed.

[0055] In the above step 6, the filling soil blocks and gravel are made so that the height of the filling soil blocks and gravel is the same height as or lower than the upper reinforcement plate 1. After tightening the anchor nut on the upper reinforcement plate 1, a nut chuck can be installed on the upper part of the upper reinforcement plate 1 and fasteners can be used to fix the nut chuck and the upper reinforcement plate 1 together, and then continue to fill the soil blocks and gravel.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0057] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
