Description

Technical Field

[0001] The utility model relates to the technical field of quick maintenance devices, in particular to a quick maintenance device for a gas pipeline. Background Art

[0002] The quick repair device is used for quick repair of damaged surfaces of gas pipelines. The quick repair device consists of a first semicircular plate, a second semicircular plate, a sealing gasket, a block, and a latch. When using the quick repair device, drag the first semicircular plate to move it to the damaged surface of the gas pipeline, then rotate the second semicircular plate to insert the block into the first semicircular plate, and then insert the latch into the block, thereby fixing the first semicircular plate and the second semicircular plate to the gas pipeline, so that the sealing gasket fits tightly with the damaged part of the gas pipeline, thereby sealing, and thus achieving quick repair. After waiting for the peak period of gas use, stop the gas use and further repair the gas pipeline.

[0003] The inventor discovered in his daily work that when the quick repair device is in use, the sealing gasket needs to fit tightly against the damaged part of the gas pipeline, but the quick repair device does not have a sealing inspection mechanism, making it impossible to know the sealing condition of the sealing gasket and the gas pipeline, which may lead to leakage risks. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem that in actual use, the sealing gasket needs to fit tightly against the damaged part of the gas pipeline, but the quick repair device is not provided with a sealing inspection mechanism, making it impossible to know the sealing condition of the sealing gasket and the gas pipeline, and thus there may be a hidden danger of leakage. A quick repair device for gas pipelines is proposed.

[0006] The effect achieved by the above components is: by setting up a sealing inspection component, when it is necessary to inspect the sealing between the sealing gasket and the gas pipeline, the shaken soapy water is applied to the hole of the perforated gas head. When there is an incomplete seal, the gas passes through the air inlet and the air cavity, and finally emerges from the perforated gas head, thereby blowing the soapy water into size so that the workers can see it, and then the workers reseal it until the soapy water can no longer be blown into size, thereby achieving the effect of inspecting the sealing between the sealing gasket and the gas pipeline as much as possible and reducing the risk of leakage.

[0007] Preferably, a rotating shaft is provided at the left end of the perforated air head, and an indicating arrow is fixedly connected to the arc surface of the rotating shaft.

[0009] Preferably, the arc surface of the rotating shaft is fixedly connected to a wind turbine, and a bearing is provided between the perforated air head and the rotating shaft.

[0010] The effect achieved by the above components is that when there is a leak in the seal, the gas flows through the wind turbine, causing it to rotate, thereby causing the shaft to rotate.

[0011] Preferably, the outer ring of the bearing is fixed to the air head with a hole, and the inner ring of the bearing is fixed to the rotating shaft.

[0012] The effect achieved by the above components is: by arranging the bearings, the rotation stability of the shaft is improved.

[0013] Preferably, the extrusion assembly includes an extrusion circular plate arranged on the inner arc surface of the second semicircular plate, and the extrusion circular plate is fixed to the sealing gasket.

[0014] The effects achieved by the above components are: through the pushing mechanism, the extrusion circular plate is pushed, so that the sealing gasket is pushed, so that it fits more closely with the gas pipeline.

[0015] Preferably, the arc surface of the extrusion circular plate is rotatably connected to a screw rod, and the screw rod is threadedly connected to the second semicircular plate.

[0016] The effect achieved by the above components is: twisting the screw rod pushes and squeezes the circular plate.

[0018] The effect achieved by the above components is: by setting the sliding rod, the extruded circular plate is guided.

[0019] In summary, the beneficial effects of the present invention are as follows:

[0020] In the utility model, a sealing inspection component is provided, and when the sealing between the sealing gasket and the gas pipeline needs to be inspected, the shaken soapy water is applied to the hole of the perforated gas head. When the sealing is incomplete, the gas passes through the air inlet and the air cavity, and finally emerges from the perforated gas head, thereby blowing up the soapy water so that the worker can see it. Then the worker reseals until the soapy water can no longer be blown up, thereby achieving the sealing inspection between the sealing gasket and the gas pipeline as much as possible, reducing the risk of leakage, and solving the problem that the sealing gasket needs to fit tightly with the damaged part of the gas pipeline, and the quick maintenance device has no sealing inspection mechanism, making it impossible to know the sealing condition of the sealing gasket and the gas pipeline, and thus there may be a hidden danger of leakage.

The left end of the sealing gasket 5 is fixedly connected to a perforated gas head 23 connected to the air cavity 22. By setting the sealing inspection component 2, when it is necessary to check the sealing between the sealing gasket 5 and the gas pipeline, the shaken soapy water is applied to the hole of the perforated gas head 23. When there is an incomplete seal, the gas passes through the air inlet hole 21 and the air cavity 22, and finally emerges from the perforated gas head 23, thereby blowing up the soapy water so that the worker can see it, and then the worker reseals until the soapy water can no longer be blown up, thereby reaching the sealing gasket 5 and the gas pipe as much as possible. In order to check the sealing between the channels and reduce the risk of leakage, a rotating shaft 24 is provided at the left end of the perforated gas head 23, and an indicating arrow 25 is fixedly connected to the arc surface of the rotating shaft 24. The rotating shaft 24 is rotated through the transmission mechanism, so that the indicating arrow 25 rotates, so that workers can observe the sealing condition more easily. A wind turbine 26 is fixedly connected to the arc surface of the rotating shaft 24, and a bearing 27 is provided between the perforated gas head 23 and the rotating shaft 24. When there is a leak in the seal, the gas flows through the wind turbine 26 to rotate it, so that the rotating shaft 24 rotates.

The extrusion circular plate 31 is guided by setting the sliding rod 33.

[0030] Working principle:

[0031] When using the quick repair device, drag the first semicircular plate 1 to move it to the damaged surface of the gas pipeline, then rotate the second semicircular plate 4 so that the block 6 is inserted into the first semicircular plate 1, and then insert the pin 7 into the block 6, thereby fixing the first semicircular plate 1 and the second semicircular plate 4 to the gas pipeline, so that the sealing gasket 5 fits tightly with the damaged part of the gas pipeline, thereby sealing, thereby achieving quick repair, waiting for the peak period of gas use, stop the gas before further repairing the gas pipeline, when it is necessary to check the seal between the sealing gasket 5 and the gas pipeline, apply the shaken soapy water to the hole of the perforated gas head 23, when there is incomplete sealing, the gas passes through the air inlet 21 and the air cavity 22, which is most effectively blocked by the perforated gas head. The gas head 23 comes out, thereby blowing up the soapy water so that the workers can see it, and then the workers reseal it until the soapy water can no longer be blown up, thereby achieving the purpose of checking the seal between the gasket 5 and the gas pipeline as much as possible, reducing the risk of leakage. When there is a leak in the seal, the gas flow through the wind turbine 26, causing it to rotate, causing the rotating shaft 24 to rotate, and causing the indicator arrow 25 to rotate, so that the workers can more easily observe the sealing condition. By providing the bearing 27, the rotation stability of the rotating shaft 24 is improved, and the screw 32 is turned to push the extrusion circular plate 31, so that the extrusion circular plate 31 is pushed, so that the sealing gasket 5 is pushed, so that it fits more closely with the gas pipeline, and the extrusion circular plate 31 is guided by providing the sliding rod 33.
