Abstract
Description
Technical Field
[0001] This utility model relates to the field of natural gas pipeline maintenance technology, specifically to a temporary support device for natural gas pipeline maintenance. Background Technology
[0002] Natural gas pipelines are vital energy transportation facilities connecting natural gas production and consumption areas. Accidents involving natural gas pipelines can lead to enormous direct and indirect economic losses, including gas leaks, fires, and explosions, all of which severely impact personal safety and public order. Therefore, ensuring pipeline safety is of paramount importance in maintenance work.
[0003] During pipeline maintenance, temporary support devices stabilize the pipeline, preventing accidents caused by pipeline movement or sagging. Pipelines may bend or deform during maintenance due to their own weight or other external forces; temporary support devices provide necessary support, maintaining the pipeline's original shape and structure. By stabilizing the pipeline, temporary support devices ensure that maintenance personnel can work in a safe and stable environment, thereby improving the quality of maintenance work.
[0004] The following drawbacks were discovered during subsequent use:
[0005] 1. The support device cannot adapt to pipes of different sizes. When using it, it is necessary to select according to the pipe size, and multiple sizes of support devices need to be stored, which wastes manpower.
[0006] 2. The height of the support device cannot be adjusted according to the height of the pipeline, making it impossible for the support device to provide stable support for the pipeline.
[0007] Therefore, in view of this, an improvement was made to the existing structure, and a temporary support device for natural gas pipeline maintenance was proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] As per the instruction manual Figure 1 , 2 As shown, a temporary support device for natural gas pipeline maintenance includes a bracket 1, a clamping assembly 2 for clamping the pipeline, and a support assembly 3 disposed at the bottom of the bracket 1.
[0028] As per the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, the clamping assembly 2 includes a pair of sliding members 2.1 slidably mounted on the bracket 1, a pair of rotating members 2.2 rotatably mounted on the corresponding sliding members 2.1, and a pair of fixing members 2.3 slidably mounted on the corresponding sliding members 2.1. The bracket 1 has two T-shaped grooves at its bottom, and a T-shaped slider is located at the bottom of each sliding member 2.1. A pair of threaded shafts are rotatably mounted on the bracket 1 via a pair of bearings. Each of the threaded shafts has a first knob 2.4 fixedly mounted at one end. The T-shaped slider at the bottom of the sliding member 2.1 has a threaded groove through which the threaded shafts rotate.
[0029] As per the instruction manual Figure 1 , 2As shown in Figures 3 and 4, a T-shaped slider II is provided at the bottom of the fixed component 2.3, and a T-shaped groove II is provided on the sliding component 2.1. A threaded shaft II is rotatably mounted on the sliding component 2.1, and the threaded shaft II is rotatably mounted on the sliding component 2.1 via a pair of bearings II. The threaded shaft II has two symmetrically arranged threads with opposite directions of rotation. A second knob 2.5 is fixedly mounted at one end of the threaded shaft II. The T-shaped slider II at the bottom of the fixed component 2.3 has a threaded groove II through which the threaded shaft II can rotate. A rotating shaft is provided at the bottom of the rotating component 2.2, and the rotating component 2.2 is rotatably mounted on the sliding component 2.1 via the rotating shaft. A rotating platform is provided on the sliding component 2.1 for the rotating shaft to rotate. A connecting shaft is provided on the fixed component 2.3, and a groove is provided on the rotating component 2.2 for the connecting shaft to slide. The movement of the fixed component 2.3 will drive the rotating component 2.2 to rotate along the corresponding rotating shaft. A rubber strip is provided on one side of the rotating component 2.2 to prevent the pipe from sliding.
[0030] As per the instruction manual Figure 1 , 2 As shown, the support assembly 3 includes a pair of telescopic rods 3.1 fixedly mounted on the bracket 1. Each telescopic rod 3.1 has a support plate 3.2 fixedly mounted at one end. A pair of guide rails 3.3 are mounted on the support plate 3.2. The bracket 1 has sliding grooves for the guide rails 3.3 to slide. The sliding of the guide rails 3.3 on the sliding grooves allows the support plate 3.2 to move stably. The bracket 1 has a boss for the telescopic rods 3.1 to be fixedly connected to. The fixed end of the telescopic rod 3.1 is fixedly mounted on the boss, and the moving end of the telescopic rod 3.1 is fixedly connected to the support plate 3.2. Extending or retracting the telescopic rod 3.1 moves the support plate 3.2, thereby adjusting the height of the bracket 1.
[0031] The working principle of this utility model:
[0032] Place bracket 1 at the required support location for the natural gas pipeline. Rotate the second knob 2.5 located on the sliding member 2.1. The second knob 2.5 drives the threaded shaft 2 to rotate, which in turn drives a pair of fixed members 2.3 to move in opposite directions. Since one end of the fixed member 2.3 is slidably connected to the rotating member 2.2 via a connecting shaft, and one end of the rotating member 2.2 is rotatably mounted on the sliding member 2.1 via a rotating shaft, the fixed member 2.3 slides along the groove on the rotating member 2.2, thereby driving the rotating member 2.2 to rotate along the rotating shaft. This makes the pair of rotating members 2.2 on the same sliding member 2.1 form a certain angle. Then rotate another second knob 2.5, so that the rotating member 2.2 on the other sliding member 2.1 also forms a certain angle.
[0033] Then, rotate the first knob 2.4 located on both sides of the bracket 1, which will drive the corresponding threaded shaft to rotate, causing the sliding part 2.1 to slide along the T-shaped slide groove, thereby causing the four rotating parts 2.2 to contact the pipe at the same time, fixing the position of the pipe. Then, extend a pair of telescopic rods 3.1, which will drive the support plate 3.2 to move until it contacts the ground, fixing the position of the bracket 1.
[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
