[0001] The utility model relates to the technical field of petroleum and natural gas pipelines, in particular to a locking device for petroleum and natural gas pipelines. Background Art

[0002] Oil and gas pipelines are special pipelines used to transport natural gas. Natural gas is a very important energy source, so the tightness of the connection between natural gas pipelines is crucial. During the installation of oil and gas pipelines, locking devices are required for locking and reinforcement.

[0003] At present, when using pipeline locking devices, there is a lack of a quick adjustment and positioning mechanism. Usually, the locking device requires the pipeline to be aligned, placed and leveled, and then the locking action is manually performed, which makes the operation more cumbersome and requires specific tools. The convenience of use is relatively general. Therefore, a petroleum and natural gas pipeline locking device is proposed. When performing the pipeline locking action, the use position of the locking mechanism can be adjusted by pneumatic quick control, thereby driving the pipeline to perform alignment and leveling operations, so as to facilitate the subsequent locking operation, which greatly improves the flexibility and convenience of the device.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] In order to facilitate the alignment and leveling of the pipeline and the locking operation, the flexibility and convenience of the device are greatly improved. Figure 1-3 As shown, a petroleum and natural gas pipeline locking device described in the utility model comprises a fixing component 1, a locking component 3 and a detection component 4. The locking component 3 is arranged inside the fixing component 1, and the detection component 4 is arranged on the surface of the locking component 3;

[0032] The fixing component 1 includes a fixing frame 101, a slideway 102 is provided in the fixing frame 101, a mounting component 2 is sleeved in the slideway 102, the mounting component 2 includes a push rod 201, and the slideway 102 is sleeved and connected to the push rod 201, and an annular air cushion 103 is glued to the periphery of the push rod 201 in the slideway 102.

[0033] When in use, the deformation caused by the inflation of the annular air cushion 103 pushes the push rod 201 and the locking assembly 3 to move quickly, which can achieve the initial rapid positioning and locking action of the pipeline, improve the operating convenience, and improve the efficiency of the locking operation, making it more convenient and flexible to use.

[0034] In order to increase the functionality of the device, for example, Figure 1 , Figure 4 As shown, the utility model also includes that the detection component 4 includes a recovery box 401, and an air outlet 402 is opened on the surface of the recovery box 401. A flow meter 403 is arranged on the outside of the air outlet 402, and the detection end of the flow meter 403 is located in the air outlet 402, and a one-way valve 404 is arranged at the air inlet end of the recovery box 401.

[0035] When in use, the leaked natural gas is recovered through the recovery box 401 and then measured through the flow meter 403, so that the operator can quickly judge the use effect of the locking device and the sealing of the pipeline connection.

[0036] For example, Figure 2 As shown, the utility model also includes that an annular groove 104 is opened in the fixing frame 101, and the annular groove 104 is connected to the annular air cushion 103, and a tightening screw 105 is arranged on the periphery of the fixing frame 101, and one end of the tightening screw 105 passes through the annular air cushion 103.

[0037] When in use, the annular air cushion 103 is guided through the annular groove 104 to facilitate inflation and deflation, and the pipeline is locked by threaded connection by tightening the screw 105 .

[0038] For example, Figure 3 As shown, the utility model also includes that one end of the push rod 201 is connected to the mounting seat 202 by a bolt, the bottom of the mounting seat 202 is rotatably connected to the ball 203 through a reserved ball groove, and the top of the mounting seat 202 is located on both sides of the push rod 201 and is threadedly connected to the fixing bolts 204 through reserved threaded holes.

[0039] When in use, the mounting seat 202 is conveniently connected to the arc-shaped pressing plate 301 by sliding, thereby improving the convenience of disassembling and replacing the locking assembly 3 during the locking process.

[0040] For example, Figure 5As shown, the utility model also includes that the locking assembly 3 includes an arc-shaped pressure plate 301, the outer surface of the arc-shaped pressure plate 301 is provided with a slide groove 302, the slide groove 302 is provided with a recess 303, the inner surface of the arc-shaped pressure plate 301 is provided with a guide groove 304, and the detection assembly 4 is connected to the guide groove 304.

[0041] When in use, the sliding groove 302 and the recess 303 can be used to make a sliding connection with the mounting assembly 2, so as to facilitate the removal and replacement of a damaged locking assembly 3, thereby reducing the use cost of the device.

[0042] For example, Figure 1 As shown, the utility model further includes that a gas nozzle 5 is disposed on the surface of the fixing frame 101 , and the gas nozzle 5 is connected to the annular groove 104 .

[0043] When in use, it is convenient to utilize an external air pump to connect the air nozzle 5 to inflate and deflate the annular air cushion 103 through the annular groove 104 .

[0044] For example, Figure 2 As shown, the utility model also includes that the surface of the push rod 201 is provided with scale lines 6.

[0045] When in use, the scale line 6 is used to observe the use position of the push rod 201, thereby improving the accuracy of the locking operation.

[0046] When the utility model is used, the operator first sets the arc-shaped pressing plate 301 of the fixing component 1 and the locking component 3 on the periphery of two oil and gas pipelines, and uses the air pump through the air nozzle 5 to inflate the annular air cushion 103 through the annular groove 104, and uses the deformation caused by the inflation to push the push rod 201 to slide inward, so that the arc-shaped pressing plate 301 squeezes the pipeline to perform a preliminary rapid positioning and locking action, and then the locking operation of the pipeline is completed by respectively screwing the tightening screw 105 to squeeze the push rod 201. Not only is the operation simple and convenient, but it can also be operated without the traditional pre-alignment of the pipeline, and the use is more flexible and reliable;

[0047] When the sealing performance of the pipeline connection deteriorates during use, the leaked natural gas enters the recovery box 401 through the guide groove 304 and the one-way valve 404 for recovery. The operator can regularly deflate the recovery box 401 through the gas outlet 402, and use the flow meter 403 to detect the deflated flow rate, so as to quickly judge the use effect of the locking device and the sealing quality of the pipeline, so as to find the connection problems in time.

[0048] When the locking assembly 3 is damaged, the ball 203 of the mounting seat 202 can be connected with the notch 303 of the sliding groove 302 of the arc-shaped pressure plate 301 by sliding and rolling, so that the disassembly and replacement operation can be conveniently and quickly performed, which is more flexible and convenient to use and has higher practical value.
