Abstract
The utility model discloses a kind of quick inserting stacks, described drilling rod comprises the alloy steel connecting rod of triangular prism structure, and is fixed in respectively outer six side's alloy steel quick connectors and interior six side's alloy steel quick connectors at alloy steel connecting rod two ends; It is the body of rod that this drilling rod adopts Rhizoma Sparganii circular arc fin hollow alloy steel steel pipe, and two ends are six side's Quick plug-in connectors, and the body of rod and six side's Quick plug-in connectors adopt friction welding welding.This drilling rod not only can creep into by forward in coal production boring is used, and can also reverse in good time and move back brill, has the drilling rod of replacing easy, fast, thus the generation of lock of tool drilling in hole while effectively having avoided boring has ensured safety in production, also improved production efficiency, reduced cost of production simultaneously.
Description
Technical field
The utility model belongs to mining equipment field, relates to specifically a kind of quick inserting stacks.
Background technology
Country is very high to the requirement of Safety of Coal Mine Production at present, and in coal production, gas is first taken out afterwards and adopted, and must first beat gas drilling.First visit afterwards and adopt, the water drilling hole of must first prying into.This is also the necessary measure of guaranteeing that safe coal is produced, and is beating gas drilling, in water exploring drill hole, often runs into pipe becoming stuck to the inside, coal seam, makes boring cannot continue to creep into (being lock of tool drilling), thus the potential safety hazard of causing.In order to address these problems, round bur bar, auger stem, the nonreversible Three-edged drill stems of adopting at present more.
1, round bur bar, auger stem: creep into and often occur collapse hole in the weak seam of colliery, drilling rod locking, causes lock of tool drilling in hole.
2, Three-edged drill stem: although creep into, can form effective stirring action to drilling cuttings in the weak seam of colliery, be beneficial to deslagging, can not reverse and move back brill, sometimes also can cause lock of tool drilling, bring threat to Safety of Coal Mine Production.
Utility model content
The purpose of this utility model is just in order to solve the existing weak point of above-mentioned prior art, and provide a kind of quick inserting stacks, this drilling rod is at drilling hole for underground gas drainage in coal mine, particularly, in the time of weak seam construction drill, solve due to geostatic stress gas stress, the factors such as drilling rod vibrations, and in drilling process, often there is local collapse hole, the problems such as drilling rod locking, have avoided the generation of lock of tool drilling.
The utility model is realized the technical scheme that above-mentioned purpose adopts: a kind of quick inserting stacks comprises the alloy steel connecting rod of triangular prism structure, and being fixed in respectively outer six side's alloy steel quick connectors and interior six side's alloy steel quick connectors at alloy steel connecting rod two ends, the rib portion of described alloy steel connecting rod is arc-shaped structure.
Alloy steel connecting rod described in the utility model is open-core type structure.
Mode and alloy steel connecting rod that outer six side's alloy steel quick connectors described in the utility model and interior six side's alloy steel quick connectors weld by friction welding are fixed together.
Operating principle of the present utility model is: in the time that the utility model creeps in the weak seam of colliery, because the drilling rod body of rod (alloy steel connecting rod) is Rhizoma Sparganii circular arc fin shape, in drilling process, can form effective stirring action to drilling cuttings (cinder), drilling cuttings can deposit buildup, under the effect of high pressure wind-force (or waterpower), chip removal is smooth, is difficult for bit freezing.Three fins of Rhizoma Sparganii circular arc fin six side's quick inserting stacks can form the continual greasy reinforcing of smearing to borehole wall in drilling process, make borehole wall strengthening; Make to hole straight, not bending, ensure that drilling rod creeps into freedom in boring, is difficult for bit freezing.Six side's Quick plug-in connectors make drilling rod can in the time creeping into, reverse in good time and move back brill, accelerate to change the speed of drilling rod, ensure not bit freezing of drilling construction safety, thereby have improved production efficiency.
The beneficial effect that the utility model adopts technique scheme to bring is: it is the body of rod that the utility model adopts Rhizoma Sparganii circular arc fin hollow alloy steel steel pipe, and two ends are six side's Quick plug-in connectors, and the body of rod and joint adopt friction welding welding.This drilling rod not only can creep into by forward, can also reverse in good time and move back brill, changes drilling rod easy, quick, thereby the generation of lock of tool drilling in hole while effectively having avoided boring has ensured safety in production, has also improved production efficiency simultaneously, has reduced cost of production.
