Abstract
The utility model relates to a mining drill pipe, in particular to a watertight drill pipe. The watertight drill pipe is hollow. A spiral screw thread is fixed on the surface of the drill pipe. The drill pipe comprises a drill magazine, a one-way valve, a drill pipe body and a tail. Two ends of the drill pipe body are connected with the drill magazine and the tail respectively. The drill magazine and the tail can be connected in a sleeving manner. The one-way valve is disposed inside the connection of the drill magazine with the drill pipe body. The watertight drill pipe has the advantages that water injected into the drill pipe is prevented from flowing out during mounting and demounting so that water resources are saved; environmental pollution can also be prevented.
Description
Technical field
The utility model relates to a kind of mining drilling rod, specifically a kind of water drilling rod that closes.
Background technology
The colliery rig of taking precautions against natural calamities is taken out in tunnel low, beats upward rock and wears in layer work progress, needs water-through jackrod and diamond bit matching operation.Domestic hollow drill is all permeability at present, in work progress, often adds a drilling rod, the water that has injected drilling rod is removed, after refilling water after good drilling rod to be connected, work, this process causes water to waste in a large number and environment is gone to pot, and affects construction speed, reduces work efficiency.
The utility model content
For water-through jackrod in prior art, cause water to waste in a large number and make the shortcomings such as environment goes to pot, the utility model provides a kind of water drilling rod that closes.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of water drilling rod that closes, drilling rod inside is hollow, the drilling rod surface is installed with screw auger, comprise and bore storehouse, one way valve, drilling rod body and bore tail, the two ends of drilling rod body are connected with the brill tail with the brill storehouse respectively, bore storehouse and can be socketed with the brill tail, and one way valve is arranged on the inside of brill storehouse and drilling rod body junction;
Described one way valve comprises spool, valve pocket, locating ring and spring, described valve pocket is set in outside spool, and be connected with the inwall that bores storehouse, the head of spool is arranged on the entrance point of valve pocket, afterbody is arranged on the port of export of valve pocket, and spring housing is located at the spool middle part surface, and the locating ring ring set is at the afterbody of spool and be connected with the inwall of the valve pocket port of export, the locating ring Compress Spring holds out against the entrance point of the head seal valve pocket of spool, and the annular position of locating ring is provided with through hole;
Described valve pocket is connected with the inner thread that bores storehouse;
Described locating ring is connected with the inner thread of the valve pocket port of export.
The beneficial effects of the utility model:
The utility model provides closes the water drilling rod, and the water that can avoid while removing and installing having injected in drilling rod flows out, and has saved great lot of water resources, and can prevent the pollution of the environment;
The utility model provides closes the water drilling rod, can improve construction speed, improve work efficiency;
The utility model provides closes the water drilling rod, and in the time of can preventing Gas Outburst, pernicious gas enters the fresh distinguished and admirable expansion that causes the accident.
The accompanying drawing explanation

Reference numeral: 1, bore storehouse, 2, one way valve, 3, the drilling rod body, 4, auger, 5, bore tail, 2-1, spool, 2-2, valve pocket, 2-3, locating ring, 2-4, spring.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is further elaborated.
As shown in the figure: a kind of water drilling rod that closes, drilling rod inside is hollow, the drilling rod surface is installed with screw auger 4, comprise and bore storehouse 1, one way valve 2, drilling rod body 3 and bore tail 5, the two ends of drilling rod body 3 are connected with brill tail 5 with brill storehouse 1 respectively, bore storehouse 1 and can be socketed with brill tail 5, one way valve 2 is arranged on the inside of boring storehouse 1 and drilling rod body 3 junctions;
Described one way valve 2 comprises spool 2-1, valve pocket 2-2, locating ring 2-3 and spring 2-4, described valve pocket 2-2 is set in outside spool 2-1, and be connected with the inner thread that bores storehouse 1, the head of spool 2-1 is arranged on the entrance point of valve pocket 2-2, afterbody is arranged on the port of export of valve pocket 2-2, spring 2-4 is set in spool 2-1 middle part surface, locating ring 2-3 ring set is at the afterbody of spool 2-1 and be connected with the inner thread of the valve pocket 2-2 port of export, locating ring 2-3 Compress Spring holds out against the entrance point of the head seal valve pocket 2-2 of spool 2-1, and the annular position of locating ring 2-3 is provided with through hole.
When water filling in drilling rod, water pressure pushing spool 2-1 Compress Spring 2-4 moves to the port of export of valve pocket 2-2, the entrance point of valve pocket 2-2 is opened, and water is injected in drilling rod, when stopping water filling, the entrance point of valve pocket 2-2 is in naturally holding out against closed condition, therefore in work progress, in the time of need to adding stacks and loaded and unloaded, the water in drilling rod is sealed and can not flow out, can save great lot of water resources, and can prevent the pollution of the environment.
