Description

The hand-hold gasoline rig

The purpose of this utility model provides a kind of hand-hold gasoline rig, this rig can be in rock, concrete and stratum, the face of land under the no electrical environment be with the gasoline engine power with diamond bit manpower hand held drilling or get cylindrical core sample, be applied to fields such as geological and mineral generaI investigation, highway structure installation.

In the prospecting of geologic prospecting and mineral products, often need pound the solution of boring sample by manpower on the face of land with hand hammer in the past at sampling surface, waste time and energy and the sample quality bad; In highway construction, often need boring to establish road sign label, protection safety fence or inspection by sampling mud and coagulate the soil surface quality; In addition, in The mountains are high and the roads are steep the unapproachable place of large equipment, at rock, less shot hole, installing hole or the thief hole of the concrete drill degree of depth, all need the light gasoline rig of this hand-held as need.The hand held electric drill of domestic production does not at present have electrical environment in the open air can't be used, and paleomagnetism gasoline sampler drill boring bore is only limit 30 millimeters of whats, about 10 centimeters of the degree of depth, and the scope of application is very limited.And internal combustion type rigs such as other gasoline engine mostly are the big very heavy machine of volume, can't single hand-held.

The development of this rig need choose that a kind of power is suitable, and weight is lighter, and volume is less, is easy to open-air the maintenance, is easy to solve accessory, suitable hand-held gasoline engine model.In addition, the output speed of rig main shaft will be designed to be suitable for the requirement of diamond bit to rotational line speed, and water route sealing is reliable, and each connector should be made every effort to compact conformation under the enough prerequisite of intensity, in light weight, connects reliable.

The hand-hold gasoline rig that the utility model provides is a kind of single self-powered portable facility, be equipped with diamond bit and water supplying apparatus, can the larger aperture drill hole sampling, the maximum diameter of hole can reach 76 millimeters in medium-hard rock, maximum drilling depth can reach 500 millimeters under this aperture, and creeps into the aperture and the degree of depth can be bigger in the soft rock.

The utility model is to realize by choosing parts such as the homemade light-duty gasoline engine configuration reducer on a kind of hand-held forest chain saw, last lower casing, gyrator, main shaft.Reducer and gyrator be simplified structure as far as possible, reduce volume, one end of reducer inner pinion gear is designed to tooth embedding shape, can directly engage with output shaft of gasoline engine, last lower casing to alleviate complete machine weight, in addition, is provided with two-way ceramic machinery sealing with the aluminium alloys manufacturing in the gyrator water route in the utility model, can effectively prevent to leak, and have long application life; Main shaft of the present utility model and reduction gearing are with being threaded and pinning with locking nut and special lock washer, to bear bigger lower pulling force; Reducer is taked two reduction gear, can make output speed pass through the gasoline engine throttle regulates between 600 rev/mins to 1000 rev/mins, to adapt to the requirement of diamond bit to linear velocity, gasoline engine lower end and last shell and go up being connected of shell and lower casing all directly to anchor a screw tightening, and gyrator shell and lower casing are for being threaded, connect reliably convenient disassembly.

Fig. 1 is a hand-hold gasoline rig schematic appearance

Fig. 2 is that the connection of hand-hold gasoline rig, deceleration, revolving structure are always schemed

Fig. 1 shows, this hand-hold gasoline rig is mainly by Top carry handle 21, assistant is 22, gasoline engine 23, reducer 24, water chews 25, gyrator 26 and main shaft 27 are formed, main shaft 27 lower ends are male thread, during boring, main shaft 27 joins by the connecting thread and the diamond bit of lower end, operating personnel apply drilling pressure by Top carry handle 21, assistant bears reaction torque to 22, the effect of reducer 24 is the rotating speeds with the extremely suitable diamond drilling of high speed drop of gasoline engine, and the effect of gyrator 26 is except transmitting rotary motive power, also chews 25 by water and plays a part to provide and control the drill bit cooling fluid.

Figure 2 shows that structure of the present utility model always schemes, the left end of last shell 1 (i.e. upper end) is designed to locate straight button, and be connected with gasoline engine with screw, the double reduction helical gear is housed: driving gear 2, duplicate gear 14 and second level driven gear 6 in the space that last shell right-hand member (being the lower end) and lower casing 3 are formed, they form reducer, the left end of the driving gear 2 in reducer is processed into tooth embedding shape, can with output shaft of gasoline engine mutually interlock to transmit gasoline engine power; The driving gear of reducer is support with bearing 12, and the two ends of duplicate gear 14 are supported with bearing 13.When output shaft of gasoline engine rotated, the reducer driving gear and then rotated, and all rotated thereby drive duplicate gear 14, driven gear 6 and main shaft 17, and diamond bit is started working; Gyrator shell 9 and interior part thereof are formed gyrator, and gyrator shell 9 and lower casing 3 are for being threaded and locating with screw 7.

In gyrator, main shaft 17 supports with bearing 15 and 18, its left end and reducer driven gear 6 link to each other with screw thread, and pin with lock washer 5 and locking nut 4, reinforced seal 16 and two-way ceramic machinery sealing 8,11 are installed between main shaft 17 and the gyrator shell 9 and cross water swivel 10, be drilled with the limbers in the main shaft.

This rig takes aluminium alloys to do shell, and each part is installed compact and reduced unnecessary connector as far as possible.

The two-way ceramic machinery sealing sealing waterway that the utility model adopts is to be combined by the special water swivel 10 of crossing by two unidirectional ceramic machinery sealings, two mechanical seal springs about this is crossed the water swivel both sides and props up, the centre then has the limbers, thereby both guaranteed the sealing performance of mechanical seal, and made the water route unobstructed again.

The left part diameter of main shaft 17 is less than the right part diameter, and during assembling, main shaft pierces into from gyrator shell right part, and makes main shaft right side step seat on bearing 18, and like this, the pressure of the drill can directly act on the gyrator shell by bearing 18 during boring.The left end of main shaft and driven reduction gearing 6 are joined, and adopt to be threaded and to pin with locknut, and the interior pin of lock washer 4 are to insert in the pincers groove of main shaft left end, can effectively prevent the main shaft unlikely generation returning of locking nut phenomenon when forward and reverse revolution.

Because adopted that above-mentioned technology and measure, this hand petroleum drilling machine have that weight is light, small volume, power rotating speed are suitable, The characteristics such as dependable performance are suitable for single carrying and carry out open-air bore operation.
