Abstract
The utility model discloses an all-hydraulic down-hole drill head. One end of a casing (4) is provided with a low-speed and high-twist-pitch hydraulic motor (3), and the low-speed and high-twist-pitch hydraulic motor (3) is connected with a main shaft (7) by adopting the embedded type transmission. The main shaft (7) is arranged on the casing (4) and is provided with a stopping locking nut (5) through a cylindrical roller bearing (6) depending on one end of the low-speed and high-twist-pitch hydraulic motor (3). One end of an end housing (9) near to the casing (4) is arranged on the casing (4) through a double-row tapered roller bearing (8). An intake casing tube (2) is arranged coaxially in the low-speed and high-twist-pitch hydraulic motor (3), adopts the static seal with the main shaft (7), and adopts the dynamic seal with an intake housing (1) on the low-speed and high-twist-pitch hydraulic motor (3). The all-hydraulic down-hole drill head of the utility model has the advantages of simple driving device, convenient maintenance repair, high operation efficiency, low consume and low maintenance cost.
Description
Technical field
The utility model relates to a kind of all-hydraulic down-the-hole drill, particularly relates to a kind of all-hydraulic down-the-hole drill unit head.
Background technology
Down-the-hole drill is widely used in the engineering explosion hole drill cutter operations such as metallurgy, coal, building materials, railway, construction of hydropower facilities, national defense construction and the cubic metre of earth and stone.Slew gear is one of crucial driver part in the operation of down-the-hole drill Drilling, its technical performance, reliability, maintenance and repair and processing and manufacturing direct relation rig operating efficiency and cost.Traditional slew gear mostly is motor greatly or high speed liquid (gas) pressure motor adds the gear reduction kind of drive, movable sealing is all adopted at air inlet sleeve pipe two ends, cause sealing effectiveness not good, transmission mechanism complexity, maintenance and repair trouble make that operating efficiency is low, consume high, working service cost height.
The utility model content
Technical problem to be solved in the utility model provides that a kind of transmission mechanism is simple, maintenance and repair is convenient, operating efficiency height, the all-hydraulic down-the-hole drill unit head that consumption is low, the working service cost is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise housing, be installed in main shaft and air inlet sleeve pipe in the housing, be provided with low speed large torque hydraulic motor at described housing one end, described low speed large torque hydraulic motor and described main shaft adopt embedded driving coupling, described main shaft is installed on the described housing by described low speed large torque hydraulic motor one end by garden post roller bearing and is provided with the Stop-motion lock jack panel, end cap one end by described housing is installed on the described housing by biserial garden awl roller bearing, described air inlet sleeve pipe is by described low speed large torque hydraulic motor hollow shaft, insert respectively in described main shaft and the air inlet end cap at two, adopt static seal with described main shaft, adopt movable sealing with the air inlet end cap.
As a kind of improvement of the present utility model, on described main shaft, be provided with the dust cap that cooperates with described end cap.
Adopt the all-hydraulic down-the-hole drill unit head of technique scheme, have following advantage:
1. low speed large torque fluid motor-driven has been exempted gear reduction, and processing and manufacturing is easier, has reduced manufacturing cost, has improved the mechanism driving reliability;
2. the special seal of air inlet sleeve pipe is handled, and it is quiet into one moving one to become the two ends movable sealing, has improved sealing performance significantly, and has been convenient to maintaining;
3. Installation and Debugging both had been convenient in the application of Stop-motion lock jack panel, can effectively protect just anti-loosening property under impact shock load again;
4. adopt the modular design of biserial garden awl roller bearing and garden post roller bearing, suitably strengthen support interval, effectively improve the stress of main shaft, improved its reliability and application life;
5. dust cap adopts the spring column pin locking positioning, and is both solid and reliable, is convenient to keep in repair dismounting again.
In sum, the utility model is that a kind of transmission mechanism is simple, maintenance and repair convenient, operating efficiency height, the all-hydraulic down-the-hole drill unit head that consumption is low, the working service cost is low.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to accompanying drawing, be provided with low speed large torque hydraulic motor 3 at housing 4 one ends, low speed large torque hydraulic motor 3 adopts embedded driving coupling with main shaft 7, main shaft 7 is installed on the housing 4 by low speed large torque hydraulic motor 3 one ends by garden post roller bearing 6 and is provided with Stop-motion lock jack panel 5, end cap 9 one ends by housing 4 are installed on the housing 4 by biserial garden awl roller bearing 8, air inlet sleeve pipe 2 coaxial being located in the low speed large torque hydraulic motor 3, adopt static seal with main shaft 7, adopt movable sealing with the air inlet end cap 1 that is installed on the low speed large torque hydraulic motor 3, on main shaft 7, be provided with the dust cap 10 that cooperates with end cap 9.
Start 7 rotations of low speed large torque hydraulic motor 3 drive shaft and finish construction operation, low speed large torque hydraulic motor 3 direct drive shaft 7 have been exempted gear reduction, and processing and manufacturing is easier, has reduced manufacturing cost, has improved the mechanism driving reliability; Air inlet sleeve pipe 2 is a static seal with main shaft 7, be movable sealing with air inlet end cap 1, improved sealing performance significantly, and be convenient to maintaining, when the sealing device of maintenance air inlet sleeve pipe 2 and main shaft 7, only need air inlet end cap 1 is disassembled from low speed large torque hydraulic motor 3, will not disassemble from housing 4 by low speed large torque hydraulic motor 3; Installation and Debugging both had been convenient in the application of Stop-motion lock jack panel 5, can effectively protect positive main shaft 7 anti-loosening property under impact shock load again; Adopt the modular design of biserial garden awl roller bearing 8 and garden post roller bearing 6, suitably strengthened the support interval of bearing, effectively improve the stress of main shaft 7, improved its reliability and application life; Dust cap 10 adopts the spring column pin locking positioning, and is both solid and reliable, is convenient to keep in repair dismounting again.
