[0002] When transporting natural gas, generally, an underground gas pipeline buried underground is connected to a building gas pipeline in a building for transportation. When laying the underground gas pipeline buried underground, the laying of the gas pipeline will be affected by the foundation. If the foundation settles, the pipeline is prone to longitudinal uneven settlement risks together with the soil layer or by itself. Eventually, it is easy to cause misalignment, cracking, etc. at the weld position of the pipeline, thus easily causing gas leakage and affecting the normal operation of the urban gas supply system.

[0003] At present, the existing underground gas pipeline and the building gas pipeline are connected by a metal hose to compensate for their offset and offset the misalignment between the underground gas pipeline and the building gas pipeline. However, at present, the installation of the underground gas pipeline, the building gas pipeline and the metal hose is relatively inconvenient, and it is not easy to pre-align and limit the connection between the underground gas pipeline, the building gas pipeline and the metal hose, so the installation is relatively troublesome.

[0017] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0018] As Figures 1 to 4In the embodiment of the gas pipeline anti-settlement device of the present utility model shown, the gas pipeline anti-settlement device includes a metal hose 3 installed between an underground gas pipeline 1 and a building gas pipeline 2. Installation discs 4 are respectively fixedly connected to the connection ends of the underground gas pipeline 1 and the building gas pipeline 2 with the metal hose 3. Fixing discs 5 are respectively fixed at both ends of the metal hose 3. The two fixing discs 5 are respectively connected to the corresponding installation discs 4 through a plurality of bolts. A plurality of limiting holes arranged in an annular array are formed in the installation disc 4. A plurality of limiting columns 6 corresponding to the limiting holes one by one are fixed on one side of the fixing disc 5. The plurality of limiting columns 6 can be slidably connected to the corresponding limiting holes. Two relatively arranged supports 7 are fixed inside the fixing disc 5. A connecting rod 8 is rotatably connected to the inside of the support 7 through a rotating shaft. One end of the connecting rod 8 is slidably connected with a sliding frame 9. One end of the connecting rod 8 is fixedly connected to the sliding frame 9 through a tension spring. A clamping block 10 is fixed on one side of the sliding frame 9. The clamping block 10 can be in contact with one side of the corresponding installation disc 4. By fixedly installing the building gas pipeline 2 to an external building and burying the underground gas pipeline 1 underground, when installing the metal hose 3, by inserting the plurality of limiting columns 6 into the corresponding limiting holes respectively, the function of limiting the two when installing the installation disc 4 and the fixing disc 5 is achieved. By passing one end of the connecting rod 8 through the corresponding installation disc 4 and making the clamping block 10 contact one side of the installation disc 4 under the action of the tension spring, the function of pre-aligning between the fixing disc 5 and the installation disc 4 is further achieved. Then, the fixing disc 5 and the installation disc 4 are connected through bolts, avoiding manually fixing the position between the fixing disc 5 and the installation disc 4 when tightening the bolts.

[0019] In an embodiment of the present application, preferably, both ends of the rotating shaft are respectively fixedly connected to the support 7 through torsion springs 11, so that the connecting rod 8 is in a horizontal state under the action of the torsion springs 11 under normal conditions. Since the metal hose 3 can be deformed, when it is necessary to separate the clamping block 10 from the installation disc 4, by pressing one end of the connecting rod 8 in the metal hose 3 away from the clamping block 10, the clamping block 10 can be made to tilt, thus facilitating the separation of the clamping block 10 from the installation disc 4.

[0020] In an embodiment of the present application, preferably, one end of the clamping block 10 is an inclined surface, and the inclined surface of the clamping block 10 can be in contact with the corresponding installation disc 4. Through the setting of the inclined surface of the clamping block 10, it is convenient to pass one end of the connecting rod 8 through the corresponding installation disc 4.

[0021] In an embodiment of the present application, preferably, a sealing ring 12 is provided between the corresponding installation disc 4 and the fixing disc 5. Through the setting of the sealing ring 12, the sealing performance between the installation disc 4 and the fixing disc 5 can be enhanced.

[0022] In an embodiment of the present application, preferably, an L-shaped rod 13 is fixed on one of the fixed disks 5, and a benchmark 14 is fixed on the other fixed disk 5. A jack is formed on the L-shaped rod 13. The bottom of the benchmark 14 can pass through the jack. A positioning seat 15 is sleeved on the benchmark 14. By presetting the height positions of the fixed disks 5 at both ends of the metal hose 3, and by making the upper side of the positioning seat 15 contact with the lower side of the L-shaped rod 13, after the underground gas pipeline 1 settles, the settlement amount can be observed through the distance between the positioning seat 15 and the L-shaped rod 13.

[0023] In an embodiment of the present application, preferably, a fastening bolt 16 is threadedly connected to one side of the positioning seat 15, and one end of the fastening bolt 16 abuts against the surface of the benchmark 14. By tightening the fastening bolt 16, the position of the positioning seat 15 on the benchmark 14 is fixed.

[0024] When the utility model is in use, the building gas pipeline 2 is fixedly installed with an external building, and the underground gas pipeline 1 is buried underground. When installing the metal hose 3, by inserting a plurality of limiting posts 6 into the corresponding limiting holes respectively, the function of limiting the installation disk 4 and the fixed disk 5 when they are installed is achieved. A sealing ring 12 is arranged between the installation disk 4 and the fixed disk 5. By passing one end of the connecting rod 8 through the corresponding installation disk 4 and making the clamping block 10 abut against one side of the installation disk 4 under the action of the tension spring, a pre-alignment function is achieved between the fixed disk 5 and the installation disk 4. Then, the fixed disk 5 and the installation disk 4 are connected by bolts, avoiding manually fixing the position between the fixed disk 5 and the installation disk 4 when tightening the bolts. Tighten the fastening bolt 16 to fix the position of the positioning seat 15 on the benchmark 14. Preset the height positions of the fixed disks 5 at both ends of the metal hose 3, and make the upper side of the positioning seat 15 contact with the lower side of the L-shaped rod 13. After the underground gas pipeline 1 settles, the settlement amount can be observed through the distance between the positioning seat 15 and the L-shaped rod 13.
