Description

Small-bore boring and hydraulic slotted liner technique integrated apparatus based on the anchor cable rig
Technical field
The utility model relates to a kind of brill and cuts integrated apparatus, especially a kind of small-bore boring and hydraulic slotted liner technique integrated apparatus based on the anchor cable rig that uses under the coal mine that be applicable to.
Background technology
The waterpower fracturing is the effective measures of the hard top of control coal, top board etc., and the propagation direction of hydraulic fracture is subjected to the influence of stress field and country rock joint fissure developmental state.According to the needs of site operation under the coal mine, need spreading range and the propagation direction in artificial control crack sometimes.When implementing directed waterpower fracturing, need be at ad-hoc location fluting or the joint-cutting of boring, induce hydraulic fracture from the people for making seam crack initiation, expansion.Traditional brill cuts integrated apparatus, is based on all that bench drill realizes, bit diameter is big, and speed of application is slow, and difficulty is installed, shifted to equipment, and can not the construction drill axial crack.Therefore, need a kind of simple device to realize creeping into fast, quick slot, and can construct axial crack and radial fissure, expanding location and the propagation direction of control hydraulic fracture are realized directed waterpower fracturing.
Summary of the invention
The purpose of this utility model is at the weak point that exists in the prior art, provide a kind of simple in structure, easy to operate, efficient is high, the small-bore boring and hydraulic slotted liner technique integrated apparatus based on the anchor cable rig of the small-bore boring that can realize constructing.
For achieving the above object, small-bore boring and hydraulic slotted liner technique integrated apparatus based on the anchor cable rig of the present utility model, comprise the anchor cable rig, be connected the chicksan on the anchor cable rig, chicksan is provided with the high pressure sealing hollow drill, and the head of high pressure sealing hollow drill is provided with brill and cuts bit Integrated; Described chicksan comprises axis of rotation and is enclosed within the outer swivel joint body of axis of rotation that have the through hole that is connected with the swivel joint body in the middle part of the axis of rotation, the swivel joint body wall is provided with the interface that connects high-pressure rubber pipe; Described brill cuts and bit Integratedly comprises drill bit, is located at a plurality of high-pressure water shot flow nozzles on the drill bit sidewall.
Be provided with the pincers cover between described anchor cable rig and the chicksan; Described chicksan and high pressure sealing hollow drill junction are provided with sealing ring.
Beneficial effect: the brill of this device cuts and is provided with the high-pressure water shot flow nozzle on the bit Integrated side, can realize that borehole axial joint-cutting and hole diameter are to joint-cutting, connect by the pincers cover, easy disassembly, carrying and installation is convenient, can realize creeping into fast, especially in top coal, top board during construction drill, speed of application advantage fast, easy to use is more obvious, can realize directed cutting of how intensive small-bore boring hydraulic slotted liner technique according to the small-bore drill bit that uses and drill pipe diameter.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1-anchor cable rig, the 2-high-pressure rubber pipe, the 3-interface, the 4-chicksan, 5-high pressure sealing hollow drill, the 6-crack, the 7-brill cuts bit Integrated, 8-high-pressure water shot flow nozzle, the 9-coal and rock, the 10-through hole, 11-clamps cover.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
As shown in Figure 1, small-bore boring and hydraulic slotted liner technique integrated apparatus based on the anchor cable rig of the present utility model, comprise anchor cable rig 1, anchor cable rig 1 front end is provided with chicksan 4, be provided with pincers cover 11 between described anchor cable rig 1 and the chicksan 4, interconnect by pincers cover 11, described chicksan 4 comprises axis of rotation and is enclosed within the outer swivel joint body of axis of rotation, the axis of rotation middle part has the through hole 10 that is connected with the swivel joint body, and the swivel joint body wall is provided with the interface 3 that connects high-pressure rubber pipe 2; Interface 3 is provided with high-pressure rubber pipe 2, and chicksan 4 front ends are provided with high pressure sealing hollow drill 5, and described high pressure sealing hollow drill 5 is hollow drill, and described chicksan 4 is provided with sealing ring with high pressure sealing hollow drill 5 junctions.The head of high pressure sealing hollow drill 5 is provided with to bore and cuts bit Integrated 7, brill cuts and bit Integrated 7 comprises drill bit, is located at a plurality of high-pressure water shot flow nozzles 8 on the drill bit sidewall, water under high pressure enters chicksan 4 through high-pressure rubber pipe 2, and enter high pressure sealing hollow drill 5 by chicksan 4, the hole of water under high pressure in the middle of high pressure sealing hollow drill 5 through drill bits, through 8 ejections of high-pressure water shot flow nozzle, form water jet at a high speed and cut coal and rock 9 and cut out crack 6 in coal and rock 9 then.
Operating principle: when using this device, cut-in pressure is the low-pressure water of 1 ~ 3MPa in high-pressure rubber pipe, open anchor cable rig 1, creep into to coal and rock 9, low-pressure water enters the chicksan 4 from high-pressure rubber pipe 2, enters axis of rotation the chicksan from the through hole 10 of chicksan 2 inside, enter high pressure sealing hollow drill 5 from axis of rotation, arrive to bore then and cut bit Integratedly 7, high-pressure water shot flow nozzle 8 ejections from the drill bit work to cool off drill bit.After rig creeps into coal and rock 9 desired depths, hydraulic pressure in the raising high-pressure rubber pipe is to more than the 10MPa, can utilize high-pressure water jet to cut two kinds of cracks this moment according to the construction needs: first kind, stop to creep into, only keep anchor cable rig 1 to drive 5 rotations of high pressure sealing hollow drill, the water under high pressure of ejection cuts the crack 6 that bit Integrated 7 radial direction cuts out an annular at brill from high-pressure water shot flow nozzle 8; Second kind, stop to creep into, anchor cable rig 1 stops the rotation, the air leg by anchor cable rig 1 repeatedly flexible drive to bore cut bit Integrated 7 and move up and down, can cut out two cracks 6 along the axial direction of boring.
