[0004] To achieve the above purpose, two support plates are placed on both sides of the excavated trench respectively to protect the gas pipeline located in the middle position of the trench and prevent the gas pipeline from being damaged during machine excavation. The strip frame is used to facilitate the installation of the first support assembly, and two adjacent support plates are supported by several first support assemblies to prevent the two support plates from tilting and tipping over during operation to damage the gas pipeline and fail to protect the gas pipeline.

[0017] Furthermore, the support assembly includes a square plate arranged on the support platform, a column is fixed on the side of the square plate away from the support platform, a lower arc plate is fixed on the side of the column away from the square plate, an upper arc plate is arranged above the lower arc plate, the upper arc plate and the lower arc plate are adapted to each other and are sleeved outside the gas pipeline, and the upper arc plate and the lower arc plate are fixed by bolts.

[0032] The technical solution of the present invention will be more clearly and completely explained below by describing the preferred embodiments of the present invention in combination with the accompanying drawings.

[0033] like Figure 1-5As shown, a gas pipeline support and protection structure of the preferred embodiment of the utility model comprises two axially arranged and relatively disposed support plates, the two support plates are respectively located on both sides of the gas pipeline and provide side protection for the gas pipeline, a plurality of axial strip frames are fixed on the opposite sides of each support plate, a plurality of first support assemblies supporting the support plates are arranged between every two adjacent strip frames, the two support plates are respectively placed on both sides of the excavated groove, and provide protection for the gas pipeline located in the middle position of the groove to avoid damage to the gas pipeline during machine excavation, the strip frames are used to facilitate the installation of the first support assembly, and the two adjacent support plates are supported by a plurality of first support assemblies to avoid the two support plates tilting and tipping over during operation to damage the gas pipeline and fail to provide protection for the gas pipeline.

[0034] like Figure 1 and Figure 2 and Figure 3 The first support assembly includes a sleeve arranged between two support plates. The inner cavity of the sleeve is hollow and open at both ends. Two support rods are slidably connected inside the sleeve. One end of each support rod extends out of the sleeve. A plurality of A circular holes are opened on the sleeve. A plurality of A cylindrical holes matching the A circular holes are opened on each support rod. The plurality of A cylindrical holes are arranged in an array. The sleeve and the support rod are fixedly connected by bolts penetrating the A circular holes and the A cylindrical holes. Each support rod is connected to an adjacent strip frame through a first connecting assembly. According to the diameter of the gas pipeline, the length of the support rod extending out of the sleeve is adjusted so that the support assembly composed of the two support rods and the sleeve supports the two support plates. The A circular hole is penetrated by bolts and a suitable A cylindrical hole is extended to fix the sleeve and the support rod, thereby reducing the possibility of the support plate tipping due to the support rod being recovered into the sleeve under pressure.

[0035] like Figure 1 and Figure 2 and Figure 3The inner cavity of the strip frame is hollow and is open toward one side and the top of the support rod. The first connecting component includes a plurality of B circular holes opened on both sides of the strip frame and connected to the inner cavity of the strip frame. A slider is slidably connected in the strip frame. The slider extends out of the strip frame. The part of the slider extending out of the strip frame is fixed with an ear seat. The ear seat is hingedly connected to the adjacent support rod. A B column hole adapted to the B circular hole is opened on the slider. The slider is fixedly connected to the strip frame by bolts penetrating the B circular hole and the B column hole. The frame is fixedly connected to facilitate the connection of the support rod and the strip frame. The ear seat is hingedly connected to the support rod, which makes it convenient for the staff to first press one of the support plates down to the bottom of the groove, and then press the other support plate down to the bottom of the groove. When the two support plates have different heights due to the uneven height of the groove bottom, the support rod and the sleeve are tilted, which does not affect the support of the two support plates by the support rod and the sleeve. At the same time, the height of the slider in the strip frame can be adjusted according to the height of the gas pipeline to avoid the support rod and the sleeve blocking the gas pipeline, thereby improving the applicability of the device.

[0036] like Figure 1 and Figure 2 When the groove depth is higher than the depth of the support plate 1, the two support plates are detachably connected with an extension component through an installation component to improve the applicability of the device.

[0037] like Figure 1 and Figure 2 The extension component includes a heightened plate arranged above the support plate, and an axial mounting frame is fixed on the opposite side of the two heightened plates. The inner cavity of the mounting frame is hollow, and the upper and lower ends and the opposite side are open. The second supporting component is connected between the two mounting frames through a second connecting component. The first connecting component has the same structure as the second connecting component, and the second supporting component has the same structure as the first supporting component. The heightened plate increases the applicable groove depth of the device, thereby improving the applicability of the device.

[0038] like Figure 1 and Figure 2 The mounting assembly includes a first plug-in block which is arranged in the mounting frame and fixedly connected to the mounting frame by bolts. The first plug-in block extends out of the mounting frame. The portion of the first plug-in block extending out of the mounting frame enters the inner cavity of the strip frame. The portion of the first plug-in block entering the inner cavity of the strip frame is fixedly connected to the strip frame by bolts. The first plug-in block enters the inner cavity of the strip frame through the top opening of the strip frame. The first plug-in block is fixed to the mounting frame and the strip frame by bolts to facilitate the fixed connection of the support plate and the heightening plate, thereby improving the stability of the device connection.

[0039] like Figure 1 and Figure 2 and Figure 3 and Figure 4In order to support the gas pipeline in the groove, a support platform is set in the middle position between the two support plates, and L-shaped plates are fixed on both sides of the support platform. The end of the L-shaped plate away from the support platform is fixed to the adjacent support plate by bolts, and the L-shaped plate and the support platform are also fixed by a crossbeam. The support platform is connected with a support component that protects and supports the gas pipeline through an assembly component. The support platform and the support plate are connected by the L-shaped plate and the crossbeam, which supports the support plate. At the same time, the gas pipeline is supported by the support plate, and the gas pipeline is supported by the support component.

[0040] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The supporting assembly includes a square plate arranged on a support platform, a column is fixed on one side of the square plate away from the support platform, a lower arc plate is fixed on one side of the column away from the square plate, an upper arc plate is arranged above the lower arc plate, the upper arc plate and the lower arc plate are adapted to each other and are sleeved outside the gas pipeline, the upper arc plate and the lower arc plate are fixed by bolts, the lower arc plate, the column and the square plate are integrally formed and support the gas pipeline, the upper arc plate and the lower arc plate are respectively sleeved outside the gas pipeline and fix and protect the gas pipeline, the upper arc plate and the lower arc plate are fixed by bolts, and the gas pipeline, the upper arc plate and the lower arc plate also form an integrated structure.

[0041] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The assembly component includes a slide groove opened on the upper surface of the support platform, a slide rail is fixed at the bottom of the slide groove, a sliding block adapted to the slide groove is slidably connected to the slide rail, the sliding block extends out of the slide groove, and the part of the sliding block extending out of the slide groove is fixed to the lower surface of the square plate. The sliding block is guided by the cooperation of the slide rail and the slide groove. When the gas pipeline is deformed by heat, the gas pipeline drives the square plate to slide on the support platform, thereby reducing the possibility of the gas pipeline expanding and rupturing due to heat.

[0042] like Figure 1 and Figure 2 In order to reduce the possibility of damage to the gas pipeline caused by debris such as soil falling from above the gas pipe during construction, a protective plate is provided above the heightening plate to protect the gas pipeline. Second plug blocks are fixed at the four end corners of the lower end surface of the protective plate. The second plug blocks extend into the top opening of the installation frame, and the part of the second plug blocks extending into the installation frame is fixedly connected to the installation frame by bolts, so as to facilitate the fixation of the protective plate and the heightening plate. The protective plate closes the gap between the two heightening plates and protects the gas pipeline located between the two heightening plates.

[0043] When in use, the staff manually digs out a trench to expose the gas pipeline located in the middle of the trench, and then places several support plates in pairs on both sides of the trench. In the initial state, the slider is fixed to the strip frame by bolts, and the support rod is manually pulled out of the casing so that the support rod and the casing cooperate to support the two support plates, and then the bolts are fixed and connected through the bolts passing through the A circular hole and the A cylindrical hole to prevent the support rod from being received into the casing under pressure. The staff uses mechanical equipment such as excavators to press one of the support plates so that the bottom of one of the support plates conflicts with the bottom of the trench, and then presses the other support plate so that the bottom of the other support plate conflicts with the bottom of the trench. Since the support rod is hingedly connected to the slider, the two support plates will not be stuck by the support rod when they are not at the same height due to the uneven bottom of the trench, thereby improving the utilization rate of the device;

[0044] After the support plate and the foundation pit collide, the staff will place the support platform at the bottom of the trench to support the gas pipeline. Then, the upper arc plate and the lower arc plate are respectively sleeved outside the gas pipeline and fixed by bolts, so that the upper arc plate, the lower arc plate, the gas pipeline, the column and the square plate are an integrated structure. One of the square plates is fixed to the support platform by bolts, and the square plates on both sides of the square plate are connected to the support platform by sliding with the cooperation of the slide rail and the slide groove. When the gas pipeline is heated and expanded, the two sides of the gas pipeline fixed to the support platform are deformed toward each other, causing the square plates on both sides to slide on the support platform, reducing the possibility of damage to the gas pipeline due to thermal expansion;

[0045] When the depth of the gas pipeline is higher than the height of the support plate, the staff inserts the first plug into the installation frame, and the first plug is fixed to the installation frame by bolts. The part of the first plug extending out of the installation frame is inserted into the strip frame and fixed to the strip frame by bolts. Through the cooperation of the heightening plate and the support plate, the soil blocks entering the groove and damaging the gas pipeline inside the groove are reduced;

[0046] Then insert the second plug into the installation frame and fix it to the installation frame by bolts, so that the protective plate can close the gap between the two heightened plates, reduce the possibility of foreign soil or debris entering the groove from above to damage the gas pipeline, and play a protective role for the gas pipeline.

[0047] The above specific implementations are only descriptions of the preferred implementations of the utility model, and do not limit the protection scope of the utility model. Under the premise of not departing from the design concept and spirit of the utility model, various deformations, substitutions and improvements made by ordinary technicians in this field to the technical solution of the utility model based on the text description and drawings provided by the utility model should all fall within the protection scope of the utility model. The protection scope of the utility model is determined by the claims.
