Technical Field

The invention relates to the technical field of pipeline repairing and fixing, in particular to a pipeline plugging device.

Background

The pipeline of transportation liquid has certain pressure to realize the flow of liquid generally at its inside liquid in the use, if the pipeline takes place the breakage and leads to liquid to leak, liquid can splash everywhere under the effect of pressure, seriously influences normal use, even stop the liquid in the liquid transportation pipeline immediately moreover and also can continue to splash not stopping flow immediately.

Application number is 201720127166.9's a patent discloses a pipeline leakage patching device is repaired to portable, it is through cup jointing two circular arc column boards in pipeline leakage point position, make the inboard sealing washer of circular arc column board just to pipeline leakage point, again through aerifing in the gasbag to connecting at circular arc column inboard side, realize the shutoff to the pipeline through gasbag extrusion sealing washer, but this kind of device is because sealed the attached shutoff of filling up in damaged area, if the damaged area adopts soft sealed pad to pass damaged area this moment greatly and is absorbed in the body, so through the great damaged area effect of sealed pad shutoff poor or just can't carry out the shutoff.

Disclosure of Invention

The invention provides a pipeline plugging device, which can be used for plugging a large damaged area to prevent liquid from splashing and aims to solve the problem of poor effect of plugging the large damaged area by a traditional plugging device.

The technical scheme is as follows: pipeline plugging device, it includes plugging device and aerating device, plugging device includes that gasbag, leading flank are curved splint, its characterized in that: the splint trailing flank is fixed with the gasbag, splint left side or right side still are equipped with the connecting block, seted up the guiding hole on the connecting block and pass through the guiding hole is connected with the guide bar, splint pass through the connecting block can along the guide bar back-and-forth movement, the bending in guide bar both ends can be right the gasbag carries on spacingly, splint upper end and lower extreme still are equipped with upper end gasbag ring sum lower extreme gasbag ring respectively, through aerating device is right gasbag, upper end gasbag ring sum lower extreme gasbag ring aerify.

It is further characterized in that:

the other side of the splint, which is opposite to the side provided with the connecting block, is also provided with the connecting block, the connecting block is connected with a guide rod through a guide hole, and the two ends of the guide rod are bent to limit the air bag;

the plugging device is connected with the connecting device, the connecting device comprises a connecting pipe, the connecting pipe is communicated with the air bag, the upper end air bag ring and the lower end air bag ring, and the air bag, the upper end air bag ring and the lower end air bag ring are inflated by the inflating device through the connecting pipe;

the connecting pipe is provided with inflation holes at intervals, the inflation holes are provided with sealing plugs, the inflation device comprises an inflation pump, an air pipe and an inflation head, the air pipe is connected with the inflation pump, the end part of the air pipe is provided with the inflation head, and the inflation head corresponds to the inflation holes;

the connecting pipe is connected with the clamping plate through a connecting rope, the connecting pipe is respectively communicated with the upper end air bag ring and the air bag through a first branch pipe and a second branch pipe, and the upper end air bag ring is communicated with the lower end air bag ring through a guide pipe;

the connecting device also comprises a rotary drum and a supporting seat, the connecting pipe is wound on the rotary drum, a rotary shaft is arranged in the middle of the rotary drum, two ends of the rotary shaft are rotatably connected with the supporting seat, and the rotary shaft is also connected with a rocking handle;

a lantern ring is sleeved at one end of the rotating shaft and positioned on the outer side of the supporting seat, the rocking handle is connected with the lantern ring, and a first locking screw is further arranged on the lantern ring;

the supporting seat is also provided with the air charging device;

the fixing device comprises a clamping frame, the clamping frame is used for being clamped with a wall, an anti-slip layer is arranged on the inner side face of the clamping frame, the clamping frame is connected with a guide frame through a sliding block, a sliding groove matched with the sliding block is formed in the guide frame, a second locking screw is connected to the sliding block, the sliding of the sliding block is limited through the second locking screw, and one end of the guide frame is connected with the connecting device through a supporting seat;

the left side or the right side of the clamping plate is also correspondingly connected with one or more rotating wheels through one or more connecting rods, and when the connecting rods and the rotating wheels are more than one, a crawler belt is connected between the rotating wheels.

After having adopted such structure, if the pipeline damage leads to liquid to splash, through the splint with plugging device around pipeline damage position, the length of splint selects to make it can surround the damage region completely according to the size in damage region, the rethread aerifys to the gasbag, make its inflation, because there is the guide bar to carry on spacingly at the gasbag rear, thereby will extrude splint after gasbag and guide bar contact and make two splint draw close the laminating thereby realize the shutoff of lateral part, aerify through the gasbag ring of upper and lower extreme, can carry out the shutoff to the gap between upper and lower end splint and the pipeline, thereby the shutoff to the pipeline is accomplished, thereby even the damage region is big as long as the size that correspondingly increases splint just can use effectively to prevent liquid from splashing.
