Abstract
The utility model discloses a hand-held pneumatic type auger. The hand-held pneumatic type auger comprises a motor gear, a motor shell body is arranged outside the motor gear, an oil seal cover is respectively arranged on the top of the motor shell body and at the bottom of the motor shell body, both ends of a central shaft of the motor gear are fixed on the oil seal covers through bearings, an airway tube is arranged on the motor shell body, the other end of the airway tube is connected with an air supply connector, the air supply connector is communicated with the inside of the motor shell body through the airway tube, and the bottom of the central shaft of the motor gear is connected with an auger bit. According to the hand-held pneumatic type auger, high-pressure air is used as a power source to drive a motor, then the motor is enabled to drive the auger bit to work, and therefore the problems that an electric drill is prone to lead to detonation and leakage of electricity are avoided. Compared with a help anchor rig, a pneumatic drill, a pneumatic pick and other equipment, the hand-held pneumatic type auger has the advantages of being light in weight, small in size, easy to operate, and the like. By means of the hand-held pneumatic type auger, underground explosion protection devices can be prevented from installation, no additional cable is needed, the weight of the gauge bit is greatly reduced, and the installation of the gauge bit is facilitated for an operator.
Description
Technical field
The utility model relates to a kind of down-hole maintenance unit, especially a kind of hand-held pneumatic type auger.
Background technology
At present, women's head-ornaments are in mining process under the coal mine, and running into main equipment component broken screw, screw corrosion through regular meeting can not be with turning or equipment is wanted interim perforating because of reinforcing.These problems seem very little, but very hard with simple manpower processing, often will waste great amount of manpower and perhaps solve with the cost of damage equipment.Because the quick-fried and electric leakage of the normal mistake that occurs of electric drill; Therefore the problem that has huge potential safety hazard; Consider above-mentioned formerly thereby can't use electric drill to solve so in the underworkings work progress, solve this type of problem, and group's windlass, air drill and pneumatic pick can not overcome the above problems because the aperture is excessive.Many times have to be transported to ground for dismounting equipment, electrification is removed, and the equipment of perhaps breaking by force in the down-hole causes equipment impaired.
The utility model content
The purpose of the utility model is: a kind of hand-held pneumatic type auger is provided, and it has avoided losing problem quick-fried and electric leakage, and in light weight, volume is little, is convenient to operation, to overcome the deficiency of prior art.
The utility model is achieved in that hand-held pneumatic type auger; Comprise motor gear; Outside motor gear, be provided with the motor case body, be equipped with oil seal cover in the top and the bottom of motor case body, bearing fixing is passed through on oil seal cover in the two ends of motor gear axis; On the motor case body, be provided with wireway, be connected with pneumatic fitting at the other end of wireway, pneumatic fitting is through the internal communication of wireway and motor case body; Bottom at the motor gear axis is connected with drill bit.
On wireway, be provided with the gas handle, the gas handle is fixed on the motor case body through set bolt, and the gas handle is connected with pneumatic fitting.Through pinning the size that gas handle enable manual control pressure-air flows into the motor case body.
Inboard at oil seal cover is provided with sealing ring.Improve the sealing effectiveness of motor case body.
When adopting the utility model to remove the corrosion screw, needn't break equipment fully, both effectively protect the equipment needn't be impaired, and practiced thrift manpower, improve the operating efficiency that equipment is torn fortune open because of breaking in the down-hole.
Run into broken screw in screw in the down-hole, need not equipment be transported to ground, can be directly the fracture screw be taken out, practice thrift great amount of time, greatly shortened equipment and torn the fortune time open, greatly improved the operating efficiency that equipment is torn fortune open.
On steel plate or plank, hole when screw is installed in the down-hole temporary needs, need not be with the equipment gug, directly can be at down-hole drilling, only need execute when boring water spray eliminate the spark that possibly occur because of friction can quick perforating.
Owing to adopted technique scheme; Compared with prior art; The utility model adopts pressure-air to come CD-ROM drive motor as power source, makes motor drive drill bit work, thus the quick-fried and electric leakage problem of mistake of having avoided electric drill to occur easily; And with group's apparatus in comparison such as windlass, air drill and pneumatic pick, have in light weight, volume is little, be convenient to advantage such as operation.Adopt the utility model can exempt the downhole anti-explosion device and install, also need not connect cable in addition, significantly reduce the weight of drill bit, be convenient to the operator and install.The utility model is simple in structure, and is easy to make, with low cost, and result of use is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
The embodiment of the utility model: the structure of hand-held pneumatic type auger is as shown in Figure 1; Comprise motor gear 1; Outside motor gear 1, be provided with motor case body 2; Top and bottom at motor case body 2 are equipped with oil seal cover 3, are provided with sealing ring in the inboard of oil seal cover 3, and bearing fixing is passed through on oil seal cover 3 in the two ends of motor gear 1 axis; On motor case body 2, be provided with wireway 5, be connected with pneumatic fitting 4 at the other end of wireway 5, pneumatic fitting 4 is through the internal communication of wireway 5 with motor case body 2; Below motor case body 2, drill bit 6 is connected the bottom of motor gear 1 axis through tapered end and nut; On wireway 5, be provided with gas handle 7, gas handle 7 is fixed on the motor case body 2 through set bolt 8, and gas handle 7 is connected with pneumatic fitting 4.
In use; Pneumatic fitting 4 is connected on the high-pressure air tube; By the flow of gas handle 7 control airs, air tilts to get in the motor case body 2 from wireway 5, and the high pressure air drives motor gear rotates at a high speed; And motor gear drives drill bit 6 high speed rotating, so just can realize holing and maybe the screw that ruptures taken out.
