Abstract
The utility model provides a novel in-hole deslagging and plugging device. The novel in-hole deslagging and plugging device is characterized in that the in-hole deslagging and plugging device can be directly sleeved on a sleeve, the in-hole deslagging and plugging device is not prone to dropping due to elasticity of rubber, and when the in-hole deslagging and plugging device is located in the sleeve in a drilling mode, multiple teeth on the in-hole deslagging and plugging device can be used for sealing an annular space between the sleeve and the hole wall, therefore, water, coal cinders and gas cannot pass through the annular space, and the hole wall can be prevented from being scoured. Special tooth profiles can guarantee that the in-hole deslagging and plugging device can be easily drilled in the sleeve, and can be difficultly disengaged. When the in-hole deslagging and plugging device is matched with double sleeve drilling, annular spaces between the sleeve and drill rods can be used for deslagging, namely in-hole deslagging can be achieved. The novel in-hole deslagging and plugging device has the advantages that scouring on the hole wall when the water, the coal cinders and the gas are discharged is reduced, and the in-hole deslagging and plugging device can be matched with double sleeve balanced drilling for use to achieve the in-hole deslagging.
Description
Technical field
The utility model relates to a kind of coal mine down-hole drilling and overlaps effective plugging device, and particularly deslagging plugging device in the novel hole that borehole casing uses is put in two-tube spy under a kind of coal mine.
Background technology
Coal mine drilling machine needs constantly to inject water under high pressure in drilling process, be used for conventional drill bit cooling of boring, deslagging and directed bore creep into, deslagging.Creeping into generation a large amount of water, cinder and gas causes hole wall to be washed away erosion for a long time along the outside discharging of boring.For burying security presence hidden danger in the hole of collapsing.Especially to the soft seam influence significantly, also be that soft seam can't be beaten one of restraining factors of depth drill.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, and deslagging plugging device in a kind of novel hole is provided.Come the annular space of shutoff sleeve pipe and hole wall by deslagging plugging device in sleeve pipe installs the hole additional, anti-sealing, cinder, gas wash away hole wall, reduce the generation factor of collapse hole, bit freezing.But utilizing the elasticity lock ring of rubber not come off on sleeve pipe, is the abrasive rubber structure, and the frictional dissipation that produces can bear sleeve pipe and creep into the time.Adopt multiple tooth structure, namely reduced frictional resistance and can reach plugging effect again.Use specific profile of tooth, for forward, conveniently enter when creeping into sleeve pipe.When the front meets obstructions, be difficult for deviating from.When cooperating two-tube creeping into, by the shutoff to sleeve pipe and hole wall annular space, bootable water, cinder, gas discharge by annular space between sleeve pipe and drilling rod, i.e. deslagging in the hole greatly reduces the generation of the hole of collapsing, bit freezing, has improved drilling efficiency and safety.
The purpose of this utility model is achieved in that and comprises deslagging plugging device, sleeve pipe, drilling rod in the hole, it is characterized in that the deslagging plugging device directly is enclosed within on the sleeve pipe in the hole, utilizes the elasticity difficult drop-off of rubber.When creeping into, multiple tooth on the deslagging plugging device can Sealed casing pipe and hole wall between annular space.Water, cinder, gas can not pass through, and the protection hole wall is not washed away.Special profile of tooth guarantees that the deslagging plugging device creeps into easily, is difficult for deviating from.When cooperating two-tube creeping into, the annular space between sleeve pipe and the drilling rod can be used for deslagging, namely realizes deslagging in the hole.
The invention has the beneficial effects as follows: reduce water, cinder, washing away hole wall when gas is discharged; Can creep into two-tube balance and be used deslagging in the realization hole.

Fig. 1 is structure chart of the present utility model
Fig. 2 is that the A of Fig. 1 is to view
The specific embodiment
Below in conjunction with accompanying drawing this example is described further
By Fig. 1-2 as can be known, deslagging plugging device 1 directly is enclosed within on the sleeve pipe 2 in the hole, utilizes the elasticity difficult drop-off of rubber.When creeping into, multiple tooth on the deslagging plugging device 1 can Sealed casing pipe 2 and hole wall 4 between annular space.Water, cinder, gas can not pass through, and protection hole wall 4 is not washed away.Special profile of tooth guarantees that deslagging plugging device 1 creeps into easily, is difficult for deviating from.When cooperating two-tube creeping into, the annular space between sleeve pipe 2 and the drilling rod 3 can be used for deslagging, namely realizes deslagging in the hole.Rubber sealing boot has a plurality of sealing teeth, and each sealing tooth all adopts tooth-shape structure, makes it easily advance to be difficult for.Deslagging plugging device material adopts abrasive rubber in the hole.The deslagging plugging device adopts multiple tooth structure in the hole.
