These problems not only seriously threaten the safety and stability of gas transportation, but also may cause safety accidents such as leakage, which poses potential risks to the safety of life and property of surrounding residents. Therefore, it is urgent to update and transform the old gas pipeline. At present, in the laying operation of new gas pipeline, a commonly used and efficient method is to wear and set the new gas pipeline inside the old gas pipeline, so as to reduce the influence on ground traffic, surrounding buildings and urban landscape, and reduce the construction cost and time cycle.

[0003] For example, the application number for "a construction device and method for non-excavation inner wearing old gas pipeline" is 202411123094.1. This technical solution focuses on the construction scene of wearing and setting new gas pipeline inside old pipeline. However, the supporting positioning support device has significant limitations. The positioning support device can only adapt to a certain diameter of old pipeline, and cannot flexibly cope with various pipe diameter conditions of old pipeline. In actual construction, urban underground pipe network is complex, and old gas pipeline has various pipe diameter specifications. The single adaptability greatly limits its application range. At the same time, the device can only assist the wearing and setting of one diameter of new pipeline, and cannot meet the diversified demand of new pipeline laying. This undoubtedly brings many inconveniences to construction personnel, increases the construction difficulty and complexity, leads to low construction efficiency, and cannot fully adapt to the diversified requirements of modern gas pipeline laying project.

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Please refer to Figures 1 to 3The utility model provides a technical scheme: a kind of positioning support device for inner wearing gas pipeline construction, including old gas pipeline 11, two first arc plate 1 and second arc plate 2 that can be buckled together are arranged in old gas pipeline 11, the outer arc surface of first arc plate 1 and second arc plate 2 is all provided with multiple can be extended or shortened and contacted pole, and the end of contacted pole close to the inner circumferential surface of old gas pipeline 11 is provided with moving wheel 10, wherein the mounting mode of moving wheel 10 is prior art, therefore no longer carry on detailed elaboration, and the outer arc surface of first arc plate 1 and second arc plate 2 is all screw thread connection with two adjusting bolt 6, and the end of adjusting bolt 6 away from the inner circumferential surface of old gas pipeline 11 is rotatably connected with top plate 7;

[0023] By the contacted pole that can be extended or shortened, operator can flexibly place the positioning support device for inner wearing gas pipeline construction in different diameter old gas pipeline 11. The setting of moving wheel 10 provides the convenience for the positioning support device synchronous movement in the process of new gas pipeline laying. In addition, with the help of adjusting bolt 6, the positioning support device for inner wearing gas pipeline construction can be adapted to different pipe diameter new gas pipeline. The convenience and versatility of the positioning support device for inner wearing gas pipeline construction in gas pipeline construction support operation provide efficient and flexible support solution for construction personnel.

[0024] Please refer to Figures 1 to 3 The two ends of second arc plate 2 are all fixedly connected with connecting block 5 with one end inserted in first arc plate 1, and the two ends of the upper surface of first arc plate 1 are all screw thread connection with fixed bolt with one end penetrating connecting block 5.

[0025] When needing to store the positioning support device for inner wearing gas pipeline construction, operator can disassemble and separate first arc plate 1 and second arc plate 2, so that the space required for device storage can be significantly reduced, and the storage work is greatly facilitated.

[0026] Please refer to Figures 1 to 2 Multiple contacted poles are all composed of fixed rod 3 and adjusting rod 4, and one end of multiple fixed rod 3 is respectively fixedly connected on corresponding first arc plate 1 or second arc plate 2, and the other end of multiple fixed rod 3 is all screw thread connection on corresponding adjusting rod 4.

[0027] Therefore, when operator rotates adjusting rod 4, the overall length of fixed rod 3 and adjusting rod 4 combination will be shortened or extended accordingly. So that the positioning support device for inner wearing gas pipeline construction can flexibly adapt to different diameter old gas pipeline 11, effectively improve the versatility and practicality of the positioning support device for inner wearing gas pipeline construction in actual construction scene.

[0028] Please refer to Figures 1 to 2The end of the adjusting rod 4 away from the fixed rod 3 is rotationally connected with a connecting circular plate 9, and a plurality of moving wheels 10 are arranged on the corresponding connecting circular plate 9.

[0029] The two ends of the top plate 7 close to the inner circumferential surface side of the old gas pipeline 11 are fixedly connected with limiting rods 12, and the ends of the plurality of limiting rods 12 away from the top plate 7 respectively penetrate the corresponding first arc plate 1 or second arc plate 2.

[0030] The limiting rods 12 are slidably connected with the first arc plate 1 and the second arc plate 2. In this way, when the operator rotates the adjusting bolt 6, the top plate 7 will be displaced close to or away from the axis of the old gas pipeline 11. In the process of moving the top plate 7, the limiting rods 12 will slide on the corresponding first arc plate 1 or second arc plate 2 synchronously, thereby ensuring the smooth and accurate movement of the top plate 7 and providing stable and reliable support adjustment function for the construction operation.

[0031] Please refer to Figures 1 to 2 The side of the top plate 7 away from the inner circumferential surface of the old gas pipeline 11 is bonded with a non-slip protective pad 8.

[0032] The non-slip protective pad 8 is made of rubber material. In actual application, the non-slip protective pad 8 can effectively protect the new gas pipeline from being scratched and worn due to direct contact with the positioning and supporting device, thereby providing comprehensive protection. On the other hand, the friction force of the rubber material surface greatly enhances the adhesion stability between the positioning and supporting device and the new gas pipeline, effectively prevents the device from sliding on the new gas pipeline, and ensures that the positioning and supporting device for the inner penetrating gas pipeline construction can be stably arranged on the new gas pipeline, thereby providing a solid foundation for the smooth progress of the construction process.

[0033] In summary, when the positioning and supporting device for the inner penetrating gas pipeline construction is used, the operator first adjusts the abutting rod according to the diameter of the old gas pipeline 11. By rotating the adjusting rod 4, the combined length of the adjusting rod 4 and the fixed rod 3 is adapted to the inner diameter of the old gas pipeline 11. After the first arc plate 1 and the second arc plate 2 are buckled, the end of the abutting rod with the moving wheels 10 will tightly abut against the inner circumferential surface of the old gas pipeline 11, thereby providing a stable support foundation for the entire device.

[0034] When installing the new gas pipeline, the operator can rotate the adjusting bolt 6 to accurately control the displacement of the top plate 7 close to or away from the axis of the old gas pipeline 11 by the auxiliary sliding of the limiting rods 12, thereby adapting to new gas pipelines of different diameters. The non-slip protective pad 8 on the top plate 7 plays a key role in protecting the new gas pipeline from being scratched and enhancing the friction force between the device and the new pipeline to prevent the device from sliding.

[0035] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
