Abstract
The utility model relates to a drill rod and drilling tool equipment, in particular to a coring drill rod with an interlayer and a drilling tool of the coring drill rod with the interlayer. The purpose is to achieve that the coring drill rod with the interlayer and the drilling tool of the coring drill rod with the interlayer are applicable to various complex working environments, particularly environments where fires and explosions easily happen. According to the technical scheme for achieving the purpose, the coring drill rod with the interlayer comprises a hollow outer layer drill rod and an inner sleeve arranged in a cavity of the outer layer drill rod in a sleeved mode, and the interlayer is formed between the outer layer drill rod and the inner sleeve. The coring drill rod with the interlayer has the advantages that the drill rod can direct feed high pressure water to the top of a drill bit through the interlayer effectively, so that the drill rod ensures that the medium in contact with the drill bit is fully wet in the drilling process, and the drill rod avoids sparks and other insecurity factors, reduces risks, promotes drilling efficiency and is clear in sampling.
Description
Technical field
The utility model relates to a kind of drilling rod, drilling tool equipment, is specially a kind of coring drill rod and drilling tool thereof of sandwich.
Background technology
At present mostly the coring drill rod that adopts of existing various rigs is that core manufactures and designs for hard rock is got, under various complex environments particularly explosive high-risk working environment consider shortcoming to some extent.Tend to run into drilling rod and set in advance inside anchor pole or other metal object situation about bumping in some highly gassy mine boring coring processes, the serious accident in case the spark that produces of bumping very easily sets off an explosion etc.
Summary of the invention
The purpose of this utility model is to provide a kind of be applicable in various complex work environment and uses (high gas, incompetent bed, soil, hard rock, soft-sediment etc.), is particularly useful for carrying out in inflammable and explosive environment coring drill rod and the drilling tool thereof of the sandwich of boring coring.
The purpose of this utility model is to adopt following technical proposals to realize: the coring drill rod of sandwich, it comprises hollow outer drilling rod and is set in the inner sleeve of outer drilling rod cavity, forms interlayer between outer drilling rod and inner sleeve.Interlayer is used for water flowing or ventilation.
Described outer drilling rod and inner sleeve are connected and fixed by the screw thread retainer ring at two ends.The screw thread retainer ring is the airtight steel loop of interior tyre screw thread, and thickness is the design size of space of outer drilling rod and inner sleeve.
Described outer drilling rod outside is provided with vane.Vane can effectively derive by rotation the powder that produces in drilling process come.
Described vane is the steel band that is wrapped in outer drilling rod outside.
A kind of drilling tool is assembled by the coring drill rod of sandwich, and coring drill rod one end connects drill bit, and the other end connects injector by joint, and injector is connected with rig.
Described inner sleeve front end is fixed on the drill bit inboard, and the rear end is fixed on the injector inboard.Interlayer between inner sleeve and outer drilling rod forms airtight unobstructed water channel or air channel.
Described drill bit is coring bit.Be the punching of a kind of middle part, the water in interlayer directly can be injected the coring bit at alloy place, can avoid occurring producing the spark cause danger after the collision of alloy and anchor pole metalloid.
Be set with fairlead in described inner sleeve.Add that according to need of work fairlead guarantees drilling direction.Fairlead can slide front and back in the drilling rod inner sleeve, play the guiding role.When the anchor pole of cut-off, reinforcing bar, fairlead sleeve pipe front end is inserted the afterbody that anchor pole is exposed, guaranteeing that drilling rod advances along the anchor pole direction in drilling process does not depart from.
The beneficial effects of the utility model are according to the narration of such scheme as can be known: by this patent drilling rod can be effectively with water under high pressure by go directly drill bit top of interlayer, guarantee that the medium that drill bit touches in drilling process is fully moistening, avoided the appearance of the unsafe factors such as spark, reduced risk, improve drilling efficiency, take a sample clear.
Description of drawings
Fig. 1 is the structural representation of the utility model coring drill rod embodiment;
Fig. 2 is the structural representation of the utility model drilling tool embodiment;
Wherein, 1 is drill bit, and 2 is fairlead, and 3 is coring drill rod, and 4 is joint, and 5 is injector, and 6 is the rig joint, and 31 is outer drilling rod, and 32 is vane, and 33 is inner sleeve, and 34 and 35 is the screw thread retainer ring.
The specific embodiment
Embodiment:
As shown in Figure 1, the coring drill rod of the utility model sandwich, it comprises hollow outer drilling rod 31 and is set in the inner sleeve 33 of outer drilling rod 31 cavitys, forms interlayer between outer drilling rod 31 and inner sleeve 33; Outer drilling rod 31 and inner sleeve 33 are connected and fixed by the screw thread retainer ring 34,35 at two ends; The screw thread retainer ring is the airtight steel loop of interior tyre screw thread, and thickness is the design size of space of outer drilling rod and inner sleeve.Outer drilling rod 31 outsides are provided with vane 32, and vane 32 is for being wrapped in the steel band of outer drilling rod 31 outsides.
As shown in Figure 2, the utility model drilling tool is assembled by the coring drill rod 3 of sandwich, and coring drill rod 3 one ends connect drill bits 1, and the other end connects injectors 5 by joint 4, and injector 5 is connected with rig by rig joint 6; Inner sleeve 33 front ends are fixed on drill bit 1 inboard, and the rear end is fixed on injector 5 inboards, and the interlayer between inner sleeve and outer drilling rod forms airtight unobstructed water channel or air channel; Be set with fairlead 2 in inner sleeve 33.
During use, water under high pressure by go directly drill bit top of interlayer, is guaranteed that the medium that drill bit touches in drilling process is fully moistening.
