Technical Field

[0002] Gas engineering refers not only to natural gas engineering, but also includes liquefied petroleum gas, coal-to-gas and heavy oil cracking gas. We use more natural gas now, so the gas engineering generally referred to now is also natural gas engineering. The scope of gas engineering is relatively wide, including large infrastructure projects such as gate stations, compressed gas stations and storage tanks, etc. General civil engineering includes: community gas pipeline network, urban gas pipeline network, gas pressure regulating station and gas pipeline installation in buildings, etc. When installing gas engineering, pipeline sealing devices are often required to seal the pipelines that have not been installed to prevent dust and debris from entering the pipeline, so as to facilitate the subsequent connection and expansion of the pipeline.

[0003] The existing pipe sealing device for gas engineering installation has low sealing efficiency during use, is cumbersome to operate, and requires the sealing part to be replaced according to the inner diameter size of the corresponding pipe. The applicability is relatively low, which brings inconvenience to the user and reduces the applicability of the device. Utility Model Content

[0005] The utility model is implemented as follows: a hydraulic sealing device for emergency repair of a gas pipeline comprises a gas pipe and a sealing cylinder, the outer wall of the sealing cylinder is fixedly connected to a cylinder, and the telescopic end of the cylinder is fixedly connected to a push plate, the push plate and the sealing cylinder are slidingly connected, the outer wall of the push plate is fixedly connected to a sealing gasket, and the outer wall of the sealing cylinder is connected to an equipment frame, the inner wall of the equipment frame is fixedly connected to an electric hydraulic rod, and the telescopic end of the electric hydraulic rod is provided with an arc-shaped splint, the outer wall of the gas pipe is fixedly connected to a controller, and the electric hydraulic rod and the cylinder and the controller are electrically connected.

[0006] Preferably, a weight sensor is provided between the electric hydraulic rod and the arc-shaped clamping plate, and the weight sensor is distributed between the cylinder and the abutment plate, and the weight sensor is electrically connected to the controller.

[0007] Preferably, the outer wall of the arc-shaped clamping plate is provided with tooth grooves.

[0010] Preferably, a warning light is fixedly connected to the outer wall of the blocking cylinder, and the warning light is electrically connected to the controller.

[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0012] When sealing a gas pipe, personnel will put the sealing cylinder on the fracture of the gas pipe. By extending the telescopic end of the electric hydraulic rod, the two arc-shaped clamping plates can be moved closer to the gas pipe, so that the two weight sensors can clamp and fix the gas pipe. By extending the telescopic end of the cylinder, the abutment plate can be moved toward the gas pipe, so that the sealing gasket can seal the fracture of the gas pipe. The gas pipe is squeezed by the abutment plate, which improves the tightness of the contact between the sealing gasket and the gas pipe, and improves the sealing between the sealing gasket and the gas pipe, thereby completing the sealing of the gas pipe.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The present invention provides a hydraulic plugging device for emergency repair of gas pipelines. Figure 1-4 As shown, it includes a gas pipe 1 and a sealing tube 2, the outer wall of the sealing tube 2 is fixedly connected to a cylinder 3, and the telescopic end of the cylinder 3 is fixedly connected to a push plate 4, the push plate 4 and the sealing tube 2 are slidingly connected, the outer wall of the push plate 4 is fixedly connected to a sealing gasket 5, and the outer wall of the sealing tube 2 is connected to an equipment frame 6, the inner wall of the equipment frame 6 is fixedly connected to an electric hydraulic rod 7, and the telescopic end of the electric hydraulic rod 7 is provided with an arc-shaped splint 8, the outer wall of the gas pipe 1 is fixedly connected to a controller 10, and the electric hydraulic rod 7 and the cylinder 3 and the controller 10 are electrically connected.

[0021] It should be noted that, since the existing gas engineering installation pipeline plugging device has a relatively low plugging efficiency when in use, it is relatively cumbersome to operate, and it is necessary to replace the plugging part according to the inner diameter size of the corresponding pipeline, and its applicability is relatively low, therefore, in order to solve the problem that the existing gas engineering installation pipeline plugging device has a relatively low plugging efficiency when in use, it is relatively cumbersome to operate, and it is necessary to replace the plugging part according to the inner diameter size of the corresponding pipeline, and its applicability is relatively low, this solution requires that when the gas pipe 1 is plugged, the personnel will set the plugging tube 2 on the fracture outlet of the gas pipe 1. By extending the telescopic end of the electric hydraulic rod 7, the two arc-shaped clamping plates 8 can be moved closer to the gas pipe 1, so that the two weight sensors 9 clamp and fix the gas pipe 1. By extending the telescopic end of the cylinder 3, the abutment plate 4 can be moved toward the gas pipe 1, so that the sealing gasket 5 can seal the fracture of the gas pipe 1. The abutment plate 4 squeezes the gas pipe 1, thereby improving the tightness of the contact between the sealing gasket 5 and the gas pipe 1 and the sealing between the sealing gasket 5 and the gas pipe 1, thereby completing the sealing of the gas pipe 1. The equipment is simple to operate and can be used to seal gas pipelines of different sizes, thereby improving the applicability of the equipment.

When the pressure between the electric hydraulic rod 7 and the arc-shaped splint 8 and the cylinder 3 and the abutment 4 reaches a set value, the controller 10 controls the electric hydraulic rod 7 and the blocking tube 2 to stop working, thereby preventing the excessive pressure between the electric hydraulic rod 7 and the arc-shaped splint 8 from causing deformation of the gas pipe 1, and preventing the excessive pressure between the cylinder 3 and the abutment 4 from causing the abutment 4 to push the gas pipe 1 to move.

[0024] In a further preferred embodiment of the present invention, Figure 3 As shown, the outer wall of the arc-shaped clamping plate 8 is provided with tooth grooves.

[0025] In this embodiment, the tooth grooves increase the friction force of the outer wall of the arc-shaped clamping plate 8 , thereby improving the stability of the arc-shaped clamping plate 8 in clamping the gas pipe 1 and preventing the gas pipe 1 from sliding between the two arc-shaped clamping plates 8 .

[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer wall of the blocking cylinder 2 is provided with glass 11 .

[0027] In this embodiment, the glass 11 facilitates personnel to observe the inside of the sealing tube 2 .

[0029] In this embodiment, the gas concentration in the sealing cylinder 2 is detected by the gas sensor 12 , and the detected concentration signal is sent to the controller 10 .

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, a warning light 13 is fixedly connected to the outer wall of the blocking cylinder 2 , and the warning light 13 is electrically connected to the controller 10 .

[0031] In this embodiment, the gas sensor 12 sends a signal to the controller 10, the controller 10 receives the signal from the gas sensor 12, the gas sensor 12 detects that the gas concentration exceeds the set value, and the controller 10 controls the warning light 13 to emit a flashing light to remind personnel that the equipment is blocked and a leak has occurred.
