Description

Sealed blowout-preventing hole device capable of synchronously rotating with drill rod

The technical field is as follows:

the utility model relates to a sealed blowout prevention hole device that can rotate with drilling rod synchronous when using in the colliery is driling in pit.

Background art:

when the coal mine underground is drilled at present, a large amount of water flow or gas is easy to gush out from the drilled hole, or the water flow and the gas are mixed to gush out, and because a gap exists between a drill rod and a blowout prevention hole of the drilling machine used at present, the drilled hole cannot be effectively plugged, the effect of sealing the water flow or the gas cannot be achieved, so that the water flow or the gas enters a roadway, casualty accidents are easy to cause, the construction safety is influenced, and the production efficiency is reduced.

The utility model has the following contents:

the utility model aims to solve the technical problem that a sealing mechanism that adopts can with drilling rod synchronous revolution is provided, can effectively carry out the shutoff to drilling, gushes out rivers or gas in avoiding the drilling, prevents rivers or gas to enter into the tunnel in to avoid the casualties accident, improve the safety of production and the sealed blowout prevention hole device that can with drilling rod synchronous revolution by a wide margin.

The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be: the utility model provides a sealed can with drilling rod synchronous revolution prevent spouting hole device's exhaust tube setting middle part on the minute flow body, the scum pipe sets up middle part under the minute flow body, the bearing housing sets up at minute flow body right-hand member, sealed waterproof bearing sets up in the bearing housing, inlay set left end in the bearing and fix and set up in sealed waterproof bearing, in the bearing is arranged in to the inflation body inlays the set, but inflation body gland is fixed and is inlayed set right-hand member and lateral shifting in the bearing, the drilling rod sealed hole sets up at the internal middle part of inflation.

The utility model has the advantages that: due to the fact that the sealing mechanism capable of rotating synchronously with the drill rod is adopted, the drill hole can be effectively plugged, water flow or gas is prevented from flowing out of the drill hole, the water flow or the gas is prevented from entering a roadway, the design is novel, the structure is simple, casualty accidents are avoided, and production safety and efficiency are greatly improved.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a right side view of fig. 1.

Fig. 3 is a left side view of fig. 1.

The specific implementation mode is as follows:

example 1: as shown in fig. 1, 2 and 3, an exhaust pipe 2 of a blowout preventing hole device capable of sealing and synchronously rotating with a drill rod is arranged in the upper middle of a flow distribution body 1, a deslagging pipe 3 is arranged in the lower middle of the flow distribution body 1, a bearing sleeve 11 is arranged at the right end of the flow distribution body 1, a waterproof sealing bearing 10 is arranged in the bearing sleeve 11, the left end of an embedded sleeve 7 in the bearing is fixedly arranged in the waterproof sealing bearing 10, an expansion body 8 is arranged in the embedded sleeve 7 in the bearing, an expansion body gland 9 is fixed at the right end of the embedded sleeve 7 in the bearing and can move transversely, and a drill rod sealing hole 12 is arranged in the middle of the expansion body 8.

Example 2: as shown in fig. 1, 2 and 3, an embedded pipe 4 is arranged in the middle of the left side of a flow distribution body 1 of the blowout preventer capable of rotating synchronously with a drill rod, one end of the embedded pipe 4 is inserted into a drill hole of a rock body, the other end of the embedded pipe is connected with the flow distribution body 1, an embedded expansion sleeve 6 is movably sleeved at the outer end of the embedded pipe 4, one end of a gas injection pipe 5 extends outwards and is connected with a gas pump, and the other end of the gas injection pipe extends into a cavity 13 to inject gas inwards and expand to form the embedded expansion sleeve 6 to seal the drill hole.

Example 3: as shown in fig. 1, 2 and 3, a cavity 13 is left at the joint of the embedded expansion sleeve 6 and the embedded pipe 4 of the blowout preventer capable of synchronously rotating with a drill pipe.

Example 4: as shown in fig. 1, 2 and 3, grooves are formed at both outer ends of an embedded expansion sleeve 6 of the blowout preventer capable of sealing a blowout preventer rotating synchronously with a drill pipe, and a steel wire 14 is fastened on an embedded pipe 4 through the grooves.

Example 5: as shown in fig. 1, 2 and 3, the expansion body 8 and the embedded expansion sleeve 6 of the blowout preventer capable of sealing the blowout preventer and rotating synchronously with the drill rod are made of rubber, high polymer materials and other non-metal materials.

Example 6: the utility model discloses an operating method:

when the device is used, the embedding expansion sleeve is firstly fastened on the embedding pipe through the steel wire, then the embedding pipe and the embedding expansion sleeve are inserted into the drill hole of the rock body, and high-pressure gas or liquid is injected into the cavity of the embedding expansion body through the gas injection pipe to expand the embedding expansion sleeve, so that the effects of sealing the drill hole and fixing the drill rod are achieved. Then the gland is moved to stretch the expansion body, a space is left in the middle position to form a drill rod sealing hole, the drill bit and the drill rod smoothly penetrate through the drill rod sealing hole, the expansion body is compacted by the movable gland, the waterproof sealing bearing is embedded in the bearing, the expansion body and the drill rod form a whole, and finally the drill rod rotates to enable the bearing to synchronously rotate, so that the effect of sealing water, slag and gas is achieved.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
