Description
The utility model relates to a kind of water and bores, and especially a kind of small-bore water of portable manual that is used for water supply industry bores.
Present small-bore water bores the drill bit that uses and mainly adopts the standard spiral bit, and so-called " small-bore " is meant at bore diameter on the Trunk Line traditionally below 50 millimeters.The cutting boring work of this traditional standard spiral bit mainly relies on two main cutting edges that the metal in the bit diameter is peeled off from level to level, make it all become metal fragment and finish boring work, this drill bit is applied on the water brill following weak point: one, drilling cuttings can pollute running water, influence health, cause the water quality accident; Two, the working angles of standard fluted drill be cutting circle with interior metal cylinder, all be converted into metal fragment through the cutting movement of drill bit, this drilling mode, ineffective power consumption is big, wastes time and energy; Three, long-pending big, the complex structure of the small-bore water drill body that uses at present, carry inconvenience.
The purpose of this utility model provides a kind of portable small-bore water and bores, but its submersible, under the situation of the normal operation of water supply Trunk Line, easy, promptly finish the work of boring, connecting branch line, simultaneously, can solve the problem that iron filings pollute running water, and improve bit cutting efficient, reduce reactive loss, reduce labor intensity, be easy to carry.
The purpose of this utility model is achieved in that a kind of portable small-bore water bores, comprise cutter head, drilling rod and ratchet handle, the fixing ratchet handle that drilling rod is rotated of drilling rod one end, the other end is fixed with can be with the cutter head of drilling rod rotation, also be with the feed spanner that can rotate relative to drilling rod on the drilling rod, the feed spanner links to each other with feed top cover, and feed top cover is replaced mutually with the shaft shoulder of drilling rod.
Described cutter head is the sleeve drill bit, and the front end of sleeve drill bit is provided with several carbide chips that is set up in parallel, and is provided with the magnet steel of powerful permanent body at the inside of sleeve drill bit, the rear portion of blade, and magnet steel is by being bolted on the drilling rod.
Bonding magnetic steel is on coupling block, and magnet steel, coupling block are provided with spring by being bolted on the drilling rod between coupling block and drilling rod.
Be with connecting tube at the drilling rod middle part, the internal diameter of connecting tube is fixed with a plug valve greater than the external diameter of drilling rod in connecting tube.
The threaded end of connecting tube is provided with a rubber blanket.
The other end of connecting tube and feed support spiral shell are solid, between be provided with a sealing gasket, be provided with O shape circle between feed support and the drilling rod.
The solid feed top cover of one end and feed support spiral shell is the T tee fitting T, the shaft shoulder place of its thread segment front end, drilling rod is provided with packing ring, a be spirally connected end of feed spanner of all the other bipass places of feed top cover, feed spanner outside is provided with balanced handle, is provided with axial back-up ring in that feed top cover is other.
Inlaying six pieces or eight pieces or ten pieces of carbide chips in that cylindrical steel sleeve end face is along the circumferential direction equidistant, is the best with eight pieces.
Drilling rod is solid drilling rod, and the sleeve drill sleeve is fixed by flat head screw in the outer end of drilling rod.
The utility model can improve bit cutting efficient owing to adopt telescopic cutter, reduces reactive loss, reduces labor intensity; Because the other magnet steel that is provided with the powerful permanent body of cutter can solve the problem that iron filings pollute running water; Owing to changed the drilling feeding structure that existing small-bore water bores, its axial length is shortened, simple in structure, the convenient use is easy to carry; In addition, but this water bores submersible, and is under the situation of the normal operation of water supply Trunk Line, easy, promptly finish the work of boring, connecting branch line.
Describe the concrete structure and the operation principle of boring in detail according to the portable small-bore water that the utility model proposes below in conjunction with accompanying drawing.
Fig. 1 is a longitudinal sectional view of the present utility model;
Fig. 2 is the partial schematic diagram of cutter head of the present utility model.
As shown in Figure 1, one end of solid drilling rod 7 is provided with sleeve drill bit 5, sleeve drill bit 5 is enclosed within the outer end of drilling rod 7, fixing by flat head screw 6, front end at sleeve drill bit 5 is provided with carbide bit 1, is provided with the magnet steel 2 of powerful permanent body at the inside of sleeve drill bit 5, the rear portion of cutter head 1, and magnet steel 2 is bonded on the coupling block, magnet steel and coupling block are fixed on the drilling rod 7 by bolt 3, are provided with spring 4 between coupling block and drilling rod 7.
Connecting tube 8 is enclosed within outside the drilling rod 7, the internal diameter of connecting tube 8 is greater than the external diameter of drilling rod 7, connecting tube is provided with screw thread and rubber blanket 20 near an end of sleeve drill bit 5, in connecting tube 8, be provided with a screwed hole, be fixed with a plug valve 10 in it, the other end of connecting tube and feed support 11 spiral shells are solid, between a sealing gasket 12 is arranged, be provided with O shape circle between feed support and the drilling rod; Feed top cover 15 is the T tee fitting T, wherein a siphunculus has screw thread outward, and it is solid with feed support 11 spiral shells, the shaft shoulder place of its thread segment front end, drilling rod 7 is provided with packing ring 14, a be spirally connected end of feed spanner 16 of all the other bipass places of feed top cover 15, feed spanner 16 outsides are provided with balanced handle 17, are provided with axial back-up ring 18 in that feed top cover 15 is other, play spacing effect, be provided with ratchet spanner 21 at the other end of drilling rod 7.
Its operation principle is as follows: the sleeve drill bit that water is bored inserts vacancy in the valve body of matching used water stopper with it, and make the screw thread of the connecting tube that water bores and the valve upper cover of water stopper screw togather fixing, rotate the feed spanner, make the feeding of water drill bit a certain amount of, the rotating ratchet spanner rotates the water drill bit and cuts then; When tube wall get through finish bore operation after, open plug valve, water will flow out through plug valve along the inwall of connecting tube and the outer wall of drilling rod with chip; Then, when the cutter head that water is bored shifts out valve body to the spheroid top, rotate an end of water stopper valve rod, make the other end of valve rod drive spheroid and rotate, make of the hollow space sealing of the spheroid face of sealing the water stopper valve body; Then water is drilled through out, connect water pipe at the screw thread place of water stopper loam cake and get final product.
The built-in powerful permanent body of the telescopic drill bit of the utility model, the effect of permanent magnet are that iron filings and the core iron that will produce in the drilling process are adsorbed on the permanent magnet, avoid entering in the pipeline foreign matter, polluted water.
