Description

Engineering roller bit
Technical field
The present invention relates to a kind of engineering roller bit.
Background technology
During the engineering drilling including oil drilling etc., it is required for carrying out fuel feeding to cone bit bearing device, with Ensure that bearing arrangement has a certain amount of lubricating oil, it is ensured that rock bit can normal work, and extend rock bit use the longevity Life.For the oiling device of the rock bit of existing structure due to its structure, typically no oil storage system, its shortcoming is work Journey rock bit at work, the loss of lubricant grease and can not be supplemented in time, influence the lubricant effect of its drill bit, and it A kind of lubricating arrangement or lubricating system for being directed to the problem of this lubricating arrangement is present afterwards and proposing, also due to its structure and note Oily mode it is unreasonable, although certain oil storage is there may be in its oiling device drill bit, because there there is no lubricating oil in it Pressure or its insufficient pressure possessed also can not just ensure gear wheel, the axle of drill bit to form lubricating oil supplement pressure differential The lubrication pressure of the lubricating oil such as bearing structure position, can not timely and effectively it be mended after the lubricant grease in drill bit is lost Fill;It ultimately results in the rise of gear wheel inner bearing temperature, rubber seal premature aging etc., and it must reduce the use of rock bit Life-span.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned the shortcomings of the prior art, there is provided a kind of engineering roller bit.The engineering Rock bit is simple and reasonable for structure, it can be ensured that being obtained all the time during the use of position including bearing arrangement etc. for drill bit is automatic Sufficient lubricating oil supplement, so that extending the service life of rock bit, saves drilling cost.
The technical scheme of engineering roller bit of the present invention includes drill body, located at the lubricating system of the drill body, The lubricating system includes shoe cream room, is connected to the grease lubrication passage of the shoe cream room, and the shoe cream room is provided with accordingly certainly Adapt to self-operated type accumulator.
The adaptive self-operated type accumulator of the shoe cream room includes the flexible type storage on the inside of the gland of the shoe cream room Energy device, and the flexible type power supply device between the flexible type energy storage device and gland.
The flexible type energy storage device includes assisting formula, ripple tub or corrugated plate type elastic energy storage located at the shoe cream room Part, the flexible type power supply device include the elasticity energy supply diaphragm or silver located at the shoe cream room.
Its lubricating system of this engineering roller bit is not only simple in structure, rationally, and making easy to process;Particularly this hair Bright lubricating system can be implemented to carry out the bearing arrangement during rock bit use automatically automatically certainly to a certain extent Make-up oil is adapted to, the continuous consumption to lubricating oil during use carries out continuous automatic pressure and adaptively supplemented, to ensure Bit cone, bearing arrangement part etc. are sufficiently lubricated from beginning to end;And then its safe running performance and can be improved By property, extend the service life of rock bit;Meanwhile its gear wheel and corresponding bearing(Axle journal)Seal have it is preferably resistance to Grind performance and sealing property;Also, due to its attachment structure and the simple and reasonability of corresponding connected mode method, its drill bit Base be connected to by way of welding it is corresponding bore in chimb, not only stable connection is reliable, when gear wheel goes wrong Or service life has arrived, it is only necessary to passes through fastener(That is bolt or stud)Can fast and easy dismounting and change rotary drill from drilling pipe Head;The maintenance and repair of rock bit can be increased substantially and change installation rate and efficiency, simplify its installation operation process, improve Installation effectiveness.
Brief description of the drawings
Fig. 1 is the example structure schematic diagram of engineering roller bit one of the present invention;Fig. 2 is the brill of engineering roller bit of the present invention The attachment structure schematic diagram of head body and corresponding drilling pipe.
Embodiment
For the technical scheme of engineering roller bit of the present invention can be further appreciated that, by following examples combination accompanying drawing to this Invention engineering roller bit is described further.
As shown in Figure 1-2.The engineering roller bit of the present embodiment includes drill body, and its drill body includes gear wheel 1, led to Cross the bit leg 2 that corresponding bit leg journel 16, corresponding gear wheel bearing arrangement etc. are connected to gear wheel, in addition to corresponding base 9;Bore Head body is provided with corresponding lubricating system, and its lubricating system includes the shoe cream room 3 located at drill body, is connected to shoe cream room and tooth Slap axle journal, bearing arrangement(Device)Grease lubrication passage 12 Deng between etc..Its shoe cream room 3 can include being opened on bit leg One blind room or blind hole.Its shoe cream room is also associated with a pouring orifice 8.
Its shoe cream room 3 is provided with adaptive self-operated type accumulator, and its adaptive self-operated type accumulator is included located at shoe cream room The flexible type energy storage device of the inner side of gland, and the flexible type energy supply dress between flexible type energy storage device and the gland Put.Its gland is connected to shoe cream room.
Its flexible type energy storage device includes the rubber corrugated plate type elastic energy storage part 4 for being connected to shoe cream room 3, rubber wave-shape board Formula elastic energy storage part 4 can be connected to shoe cream room inner circumferential side wall by its periphery air-tightness;Flexible type power supply device includes fixed connect It is connected to the corresponding inner circumferential side wall of shoe cream room or is touched by gland pressure in the metallic elastic in the outside of rubber corrugated plate type elastic energy storage part 4 Diaphragm 5 is energized, its metallic elastic energy supply diaphragm is touched in the outside wall surface of rubber corrugated plate type elastic energy storage part 4 in interior can arcuately press. It is supplied by the storage of flexible type energy storage device or its rubber corrugated plate type elastic energy storage part oil and flexible type with matching Can device or the energy supply diaphragm accumulation of energy of its metallic elastic(Resilience)Effect, utilize the continuous consumption run in rock bit to lubricating oil Reduce and during pressure reduces therewith, the change resilience of its pressure differential and carry out pressure supplement for lubricant housings in time and supply Oil.The temperature of gear wheel interior axle bearing structure can be controlled to be maintained at a relatively low state all the time, effectively avoid rubber seal etc. Premature aging, improve the service life of rock bit.
