Abstract
The utility model provides a plugging device for a double-tube directional drilling machine. The plugging device is characterized in that two casings enable rubber sealing pieces to be connected and fixed through connecting pieces, and end plates also enable sealing bodies to be fixed with the casings through connecting pieces. A connecting disc is used for fixedly connecting a connected whole and a vertical plate, used for shackling, on the underground coal mine soft and weak coal seam deep hole double-tube directional drilling machine through connecting pieces. A sealing cavity is formed by the casings, the sealing bodies and the end plates, and water, coal cinders and gas can be sealed in the sealing cavity when a driving sleeve is disassembled. When the driving sleeve is disassembled, the rubber sealing pieces in the middle are automatically contacted with a drilling rod under spring-back force to form a new seal with the casing on one side and the sleeve, and leakage can be avoided. The plugging device has the advantages of effectively reducing leakage of the water, the coal cinders and the gas when the sleeve is assembled and disassembled. The plugging device is directly connected with the drilling machine, is strong in practicability, and does not increase manpower and auxiliary work. The whole operation is naturally completed during assembly and disassembly of the sleeve, and therefore, work efficiency is improved.
Description
Technical field
The utility model relates to the two-tube directional drilling machine plugging device of weak seam deep hole under a kind of coal mine drilling machine aid, particularly a kind of coal mine.On carry out the special-purpose plugging device of annular space between shutoff sleeve pipe and the drilling rod when unloading sleeve pipe and drilling rod.
Background technology
The two-tube directional drilling machine of deep hole needs constantly to unload sleeve pipe and drilling rod in drilling process, and in dismounting sleeve pipe and drilling rod process, the leakage of water, cinder, gas can take place for sleeve pipe and drilling rod annular space, needs tool using to carry out shutoff.Present existing capping tools carries out shutoff again after the active sleeve pipe is dismantled, cause water, cinder, gas to have part to leak.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, and a kind of two-tube directional drilling machine plugging device is provided.Be that the two-tube directional drilling machine of weak seam deep hole is used the special-purpose plugging device that carries out annular space between shutoff sleeve pipe and the drilling rod when unloading sleeve pipe and drilling rod under a kind of coal mine.
The purpose of this utility model is achieved in that and comprises terminal pad, housing, rubber seal, seal and end plate, it is characterized in that, two housings are connected and fixed rubber seal by connector, and end plate is also fixed seal and housing by connector.Integral body after the connection again through terminal pad by connector and coal mine under on the two-tube directional drilling machine of weak seam deep hole the riser of shackle be connected to a fixed.Form an annular seal space by housing, seal and end plate, when guaranteeing to dismantle the active sleeve pipe, water, cinder, gas are sealed in the chamber.When unloading the active sleeve pipe, middle rubber seal contacts with drilling rod under resilience automatically, forms new sealing again with a side body and sleeve pipe, avoids revealing.
The beneficial effects of the utility model are:
The leakage of the water when 1, unloading sleeve pipe on effective minimizing the, cinder, gas;
2, plugging device directly is connected with rig, and is practical, do not increase manpower and back work;
3, because whole operation is finished naturally, increased operating efficiency in unloading sleeve pipe.
Description of drawings
Fig. 1 is structure chart of the present invention
The specific embodiment
Below in conjunction with accompanying drawing this example is described further
As shown in Figure 1, plugging device is made up of terminal pad 1, housing 2A and 2B, rubber seal 3, seal 4A and 4B and end plate 5.Terminal pad 1 is connected to a fixed by the riser of shackle on the two-tube directional drilling machine of weak seam deep hole under connector and the coal mine, and whole plugging device is connected on the rig.End plate 5A and 5B are connected and fixed seal 4A and 4B and housing 2A and 2B by connector, guarantee the band seal sealing of housing two ends.Sandwich rubber seal 3 in the middle of left and right sides housing 2A and the 2B, be fixedly clamped by connector again.Bend open generation deformation was not closed up when active sleeve pipe 8 unloads again when rubber seal 3 was dismantled at active sleeve pipe 8, and contacted sealing with drilling rod 7.
When active sleeve pipe 8 is not dismantled, by left and right sides housing 2A and 2B, seal 4A and 4B, sleeve pipe 6, initiatively sleeve pipe 8 forms annular seal space.After active sleeve pipe 8 dismounting, original annular seal space is broken, and forms new annular seal space, the sealing of realization annular space by rubber seal 3, right side housing 2B, seal 4A and 4B and sleeve pipe 6 and drilling rod 7 again.
