Description

Technical Field

[0001] The utility model relates to the technical field of pipeline blocking, in particular to a pipeline blocking device for emergency repair of pipeline networks. Background Art

[0002] During the construction process, urban water pipes or drainage pipes are often damaged by excavators when digging. Due to the rapid flow of liquid inside the pipes, the internal pressure of the pipes is very high, causing the liquid inside the pipes to gush out. The strong water pressure often makes it difficult for maintenance workers to repair the holes or broken pipes. When repairing the broken or broken pipes, the pipes need to be sealed.

[0003] The existing pipeline plugging device for emergency repair of pipeline network is also very likely to have poor plugging effect during use, thereby affecting the workers' emergency repair work on the pipeline.

[0004] The existing method of blocking the pipeline is usually to use a rubber airbag to block the water source. The rubber airbag is placed inside the pipeline and inflated so that the rubber airbag is completely engaged with the inside of the pipeline to block the water source. Since the rubber airbag is directly installed inside the pipeline for blocking, when the water flow is large, the rubber airbag cannot support the large water flow and is flushed out of the pipeline, making the rubber airbag lose its purpose of blocking the water source, thereby affecting the workers' emergency repair work on the pipeline.

The right end of the bidirectional threaded rod 202 is fixedly connected to the crank 203, and the outer wall of the grip of the crank 203 is sleeved with a sponge cover. The side walls of the bidirectional threaded rod 202 are threadedly connected to symmetrically arranged displacement brackets 204. The front sides of the displacement brackets 204 are both installed with arc-shaped clamping plates 206 through a disassembly and assembly mechanism. The inner and outer curved surfaces of the arc-shaped clamping plates 206 are bonded with rubber pads 207.

[0027] The disassembly and assembly mechanism includes a plug-in plate 2061, a slot 2041, and a fixing bolt 205. The plug-in plate 2061 is arranged on the rear wall of the arc-shaped splint 206, and a second plug-in hole 2062 is provided on the side wall of the plug-in plate 2061. The slots 2041 are all provided on the front wall of the displacement bracket 204. The left and right inner walls of the slots 2041 are provided with a plug-in hole 2042. The position of the plug-in hole 2042 corresponds to that of the plug-in hole 2062. The outer side of the fixing bolt 205 The inner sides of the first and second sockets 2042 and 2062 are threadedly connected to the nut. The insert plates 2061 are all set on the rear wall of the arc-shaped clamping plate 206. The side walls of the insert plates 2061 are provided with second sockets 2062.

[0028] The sealing assembly 3 includes a fixing ring 301, the bottom end of the fixing ring 301 is welded and fixed to the upper surface of the base 1, an inflation tube 307 is fixedly connected to the inner wall of the fixing ring 301, an inflation pump 305 is provided on the rear side of the fixing ring 301, the bottom end of the inflation pump 305 is fixedly connected to the upper surface of the base 1, the inflation hole of the inflation pump 305 is through-connected to the air inlet hole of the inflation tube 307, a baffle 303 is fixed to the outer wall of the inflation tube 307, a number of support columns 302 are welded and fixed between the rear wall of the baffle 303 and the front wall of the fixing ring 301, a connector 304 is provided at the front end of the inflation tube 307, and a rubber airbag 306 is fixedly installed on the inner wall of the connector 304. When the pipe is blocked by the dual-purpose clamping mechanism 2 and the blocking component 3, if the outer wall of the pipe is not exposed, the crank 203 is rotated to drive the two-way threaded rod 202 to rotate forward, and the two displacement brackets 204 move back to back until the two arc-shaped clamping plates 206 are against the inner wall of the pipe, thereby clamping the device inside the pipe. If the pipe diameter is small, the two-way threaded rod 202 is rotated in the opposite direction to drive the two displacement brackets 204 to move toward each other, and then drive the two arc-shaped clamping plates 206 to clamp and fix the outer wall of the pipe, which also provides stable support for the blocking component 3 when blocking, and avoids the rubber airbag 306 from detaching when the water flow is large.

The arc splint 206 of appropriate size is replaced to be suitable for pipes of different diameters, thereby improving the practicality of the device.

[0029] Working principle: When in use, when sealing the pipe, if the outer wall of the pipe is not exposed, the crank 203 is rotated to drive the two-way threaded rod 202 to rotate forward, causing the two displacement brackets 204 to move back to back until the two arc-shaped clamping plates 206 are against the inner wall of the pipe, thereby clamping and fixing the device inside the pipe. If the diameter of the pipe is small, the two-way threaded rod 202 is rotated in the opposite direction to drive the two displacement brackets 204 to move toward each other, and then drive the two arc-shaped clamping plates 206 to clamp and fix the outer wall of the pipe, which also provides stable support for the sealing component 3 when sealing, and prevents the rubber airbag 306 from detaching when the water flow is large. When sealing, the air pump 305 cooperates with the air inflation tube 307 to quickly inflate the rubber airbag 306, causing it to expand and seal the inner wall of the pipe;

[0030] When the size of the arc splint 206 is not suitable for clamping the pipe, rotate and remove the fixing bolt 205 to release the limit on the arc splint 206, and detach the insert plate 2061 from the slot 2041 to complete the disassembly, and replace the arc splint 206 with a suitable size to be suitable for pipes of different diameters.
