Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-2The present invention provides an embodiment of a gas pipeline network fastening and maintenance device for a factory, comprising two sets of symmetrically distributed fastening brackets 1, which are fixedly connected by bolts 2. A connecting base 3 is fixedly connected to each fastening bracket 1, and a threaded connecting shaft 4 is fixedly connected to the connecting base 3. A connecting device 5 is provided on the threaded connecting shaft 4. Each fastening bracket 1 includes ear plates 101, rubber clamps 102, and shape memory metal sheets 103. Two ear plates 101 are provided, and each ear plate 101 is fixed to one side of the rubber clamp 102. The shape memory metal sheet 103 is fixed inside the rubber clamp 102. The rubber clamp 102 is tightly fitted to the pipeline surface, increasing the clamping friction and preventing damage to the pipeline from rigid clamping. The shape memory metal sheet 103 has a stable shape memory effect, which is beneficial to the pipeline network. When the network vibrates slightly, it can always maintain the support force on the rubber clamp 102, ensuring the stability of the clamping and preventing the pipeline from loosening or shifting. It effectively copes with the complex working environment of the factory area. The combination structure of the rubber clamp 102 and the memory metal sheet 103 achieves the neutralization of soft connection and rigid connection. While achieving the fastening of the gas pipeline, it also achieves the effect of adapting to multiple sizes and shapes, improving the adaptability and practicality of the overall fastening bracket 1. The rubber clamp 102 has good elastic deformation capability, and the memory metal sheet 103 can adapt to the changes in the diameter of the pipeline within a certain range. With the two sets of symmetrically distributed fastening brackets 1, the clamping distance can be adjusted by bolts 2, so that the instrument can be adapted to gas pipelines of different specifications, improving the versatility of the instrument. There is no need to equip the pipeline with a separate fastening device for pipelines of different diameters, effectively reducing maintenance costs.

[0020] Reference Figure 3 A washer 104 is fixedly connected to the surface of the ear plate 101. The washer 104 is made of wear-resistant rubber material, which can effectively reduce the frictional wear between the bolt 2 and the ear plate 101. At the same time, when the bolt 2 is tightened, the washer 104 undergoes slight deformation, filling the connection gap and improving the sealing and stability of the connection. Threaded holes are opened on both the ear plate 101 and the washer 104. A screw seat 6 is fixedly connected to either of the two sets of fastening brackets 1. The surface of the bolt 2 is connected to the internal thread of the screw seat 6. A nut 7 is fixedly connected to the end of the bolt 2. A nut 8 is threadedly connected to the surface of the bolt 2. A spring washer is set between the nut 8 and the washer 104. The elastic restoring effect of the spring washer is used to prevent the nut 8 from loosening during pipeline vibration.

[0021] Reference Figure 4The connecting device 5 includes a connecting screw sleeve 51, the inside of which is threadedly connected to the surface of the threaded connecting shaft 4. A connecting telescopic member 52 is rotatably connected to the end of the connecting screw sleeve 51, and a connecting screw sleeve 53 is rotatably connected to the telescopic end of the connecting telescopic member 52. When the fastening bracket 1 needs to be connected to an external fixed bracket or a fastening bracket 1 on another pipe, the connecting screw sleeve 51 is rotated to achieve threaded installation with the threaded connecting shaft 4, and then the connecting screw sleeve 53 is rotated to fix the threaded connecting shaft 4 on the external fixed bracket or the fastening bracket 1 on another pipe, thereby achieving the effect of quick assembly and fixation.

[0022] Reference Figures 4-5 The connecting telescopic component 52 includes a fixed rod 521 and a telescopic rod 522. The end of the fixed rod 521 is rotatably connected to the end of the connecting screw sleeve 1 51. The surface of the telescopic rod 522 is slidably connected to the inside of the fixed rod 521. The end of the telescopic rod 522 away from the connecting screw sleeve 1 51 is rotatably connected to the connecting screw sleeve 2 53. A sliding groove is provided inside the fixed rod 521. A slider is fixedly connected to the telescopic rod 522. The slider is slidably connected inside the sliding groove. The telescopic structure of the connecting telescopic component 52 can adjust the distance between the instrument and the external fixed structure. The installation distance can be flexibly adjusted according to the actual distribution of the pipeline network, achieving a good adaptability to complex factory pipeline network layouts.

[0023] Reference Figures 4-5 A magnet 523 is fixedly connected inside the fixed rod 521, and an iron ring 524 is fixedly connected to the end of the telescopic rod 522. The surface of the iron ring 524 is magnetically connected to the surface of the magnet 523. Under normal conditions, the telescopic rod 522 is retracted inside the fixed rod 521. In the retracted state, the iron ring 524 and the magnet 523 fix the fixed rod 521 and the telescopic rod 522, thereby ensuring the stability of the telescopic rod 522.

[0024] Working principle: When using this gas pipeline network fastening and maintenance equipment, first adjust the distance between the two sets of fastening brackets 1 according to the diameter of the gas pipeline network. Then, attach the rubber clamps 102 of the two sets of fastening brackets 1 to the surface of the pipeline network. The rubber clamps 102 deform under the compression of the pipeline network, and the internal shape memory metal sheet 103 adapts to the shape of the pipeline network and provides support. Next, pass the bolt 2 through the threaded holes on the ear plates 101 and washer 104 of the two sets of fastening brackets 1, so that the bolt 2 is threadedly connected to the screw seat 6. Use a wrench to tighten the nut 7, causing the nut 8 to squeeze outwards. The pressure pad 104 secures the two sets of fastening brackets 1, completing the connection between the instrument and the pipeline. During the fastening process, the memory metal sheet 103 can automatically adapt and adjust according to the shape of the tube, thereby achieving the effect of adaptive fastening for tubes of different diameters and slightly deformed tubes. Through the combination of the rubber clamp 102 and the memory metal sheet 103, the soft connection and the rigid connection are neutralized, achieving the effect of fastening the gas pipeline while adapting to multiple sizes and shapes, thus improving the overall adaptability and practicality of the fastening bracket 1.

[0025] When the fastening bracket 1 needs to be connected to an external fixed bracket or another fastening bracket 1 on a pipe body, the connecting device 5 is installed on the threaded connecting shaft 4. The threaded installation with the threaded connecting shaft 4 is achieved by rotating the connecting thread sleeve 1 51. The telescopic rod 522 is adjusted within the fixed rod 521 according to the distance between the fastening bracket 1 and the fastening bracket 1 on the external fixed bracket or another pipe body. Then, the connecting thread sleeve 2 53 is rotated to fix the threaded connecting shaft 4 on the fastening bracket 1 on the external fixed bracket or another pipe body, thereby achieving the effect of quick assembly and fixation. Moreover, the installation distance of the device can be flexibly adjusted according to the actual distribution of the pipeline network, achieving a good adaptability to complex plant pipeline network layouts.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
