Abstract
The invention relates to a split type reaming bit for large-diameter raising-boring used in mining machinery and an assembly method thereof. The reaming bit for large-diameter raising-boring is of a split type structure by which the bit is split and transport dimension and weight of the bit are controlled after disassembly, which solves the difficulty of transport and assembly in a narrow roadway of a coal mine, and the reaming bit has higher stability and higher reliability under combined action of great torque, tension and impact.
Description
Technical field
The present invention relates to the drill bit in a kind of mine mechanism, be specifically related to the split type reaming bit of the anti-well drilling well of a kind of major diameter.
Background technology
The Safety of Coal Mine Production problem is an important research project, solves the Safety of Coal Mine Production problem, increases the shaft construction modes such as coalmine ventilation well, gas drainage under suction well of carrying out with regard to needs.The pit shaft excavation mainly contains the human-generated explosives pick and digs operating types such as method, freezing process, slip casting method, boring method in the prior art, but these modes are long duty cycle, and is low in economic efficiency.At present, anti-well boring method is widely used in the stable shaft construction of bottom haulage drift, geological conditions is arranged, this method duty cycle is short, labor strength is little, safe and reliable, economic and social benefit is good, but existing raise boring machine reaming bit size is less, still needs explosion just can reach the design hole diameter after oppositely completion is dug in expansion.Because the restriction of the mal-condition that the anti-well reamer bit of bored well of major diameter overall structure diameter and weight are big, the broken rock cutter of drill bit breaks rock in the shaft bottom etc. makes the major diameter reaming bit wear next technical problem in transportation, installation and other party thereof.
Summary of the invention
Main purpose of the present invention is the anti-well reamer bit of bored well of researching and developing in order to solve the narrow and small restriction of haulage drift chamber under the coal mine of split type major diameter.Because major diameter anti-well reamer bit of bored well diameter and weight are bigger, be not easy to whole Transporting, for the ease of down-hole transportation clearance and weight requirement, the anti-well reamer bit of bored well of major diameter has adopted split combination structure, drill bit is carried out structure to be split, control bit body disintegration back transportation clearance and weight simultaneously, solve a narrow transportation and an assembling difficult problem under the coal mine, this reaming bit requires to have higher stability and reliability under higher assembly precision and high pulling torque, pulling force, the impact acting in conjunction simultaneously.
The detachable split type reaming bit of major diameter of the present invention can satisfy fast, safety, major diameter pit shaft simultaneous shaft sin king needs efficiently.It is that first order bit body and the counter bore diameter that is positioned at the bottom of 3.5m is that the second level bit body of 5.0m is formed by superposed counter bore diameter mainly, the expansion part of described second level bit body links to each other by bearing pin location and bolton, forms the major diameter reaming bit of " tower ".Two bodies about the first order bit body of its middle and upper part is divided into, the centre of first order bit body are the central tube and the spline torsion pass joints of transferring power, and locking nut and cooling water pipe joint are arranged at the drill bit bottom.
The present invention also provides the method for a kind of transportation and the described reaming bit of assembly unit, is convenient to satisfy the movement requirement of reaming bit in underworkings.

The specific embodiment
As shown in Figure 1, the present invention is to be that 3.5m first order reaming bit body 6 props up mouth by its underpart by superposed counter bore diameter, with counter bore diameter is that the second level reaming bit of 5.0m is expanded part 8 and matched, with bolt 3, locking nut 4 and alignment pin 7 second level reaming bit is expanded part top panel 1 and be connected with first order reaming reaming bit lower panel 2 and form the overall structure of major diameter reaming bit, constitute " tower " structure of first order reaming bit 6 and the second level reaming bit formation that is positioned at its underpart.
With reference to Fig. 2 to Fig. 4, the left and right sides halved body 14,16 that the first order reaming bit body 6 of its middle and upper part is divided into, described left and right sides halved body 14 and 16 is connected to form an integral body jointly by alignment pin 18, bolt 19 and horizontal connecting bolt 27 and alignment pin 28 longitudinally, and wherein said connecting bolt 27 and alignment pin 28 are positioned on the detachable tool rest 26; The second level reaming bit of bottom is expanded part 8 and is linked to each other with the junction plate 11 of left and right sides halfbody with locking nut 12 by bolt 10 by the left and right halved body 9,13 of expanding part, thereby forms whole second level reaming bit.
Raise boring machine by drilling rod with after the central tube 20 of first order reaming bit body is connected, give broken rock cutter 25 by the torsion pass spline 24 that central tube 20 cooperates with spline housing 21 with transmission of power, the locking nut 22 of first order reaming bit body 6 bottoms bears brokenly the lifting force of rock pressure power and rig simultaneously, guarantees broken required moment of torsion and the lifting force of rock of broken rock cutter.Cooling tube joint 23 is to rely on the cooling water of top borer drill rod core space to cooling in the broken rock process of broken rock cutter 25 rollings, prolongs cutter life.For ease of the assembling of bit body, arranged hole for hoist 17 at the bit body branch.Because in the anti-well boring method drilling process, behind the broken rock of bit body, the rock slag is by last free-falling down certainly, major diameter reaming bit simultaneous shaft sin king section is bigger, for guaranteeing that the kata-rocks slag will not break the rock cutter and stop up, avoid the repetition fragmentation, improve efficiency of breaking rock, on the first reaming bit body, be furnished with Lou cinder hole 15.
In the shaft bottom transportation of carrying out reaming bit and assembly unit process, carry out according to following steps:
The first step, earlier transportation second level reaming bit wherein half, it is placed in the good space of the pre-pick in shaft bottom;
In second step, the left and right two halves of transporting first order reaming bit respectively is in the chamber of shaft bottom;
In the 3rd step, second half places transportation second level reaming bit to the pit shaft entrance;
The 4th step, with after the first order reaming bit left and right sides two halves assembling, treat that pilot hole creeps into open-work after, take off the guide hole drill bit and change first reaming bit, be promoted to rational position and place;
The 5th step, utilize first order reaming bit flange in the bottom dish, special-purpose boom hoisting is installed, assembly unit second level reaming bit.
Major advantage of the present invention is, the major diameter reaming bit adopts the trapezium structure of " tower ", It is tilted conical with the rock contact-making surface that the bottom drill bit is expanded part, can guarantee that reaming bit is in broken rock work In resistance to overturning, prevent that the upper drill bit body from causing swinging of drilling tool because broken rock impacts; The drill bit overall structure is simple, and the single-piece transportation clearance is little, in light weight after splitting, and it is narrow to satisfy the down-hole The movement requirement in tunnel provides the method for reaming bit transportation with assembly unit simultaneously, and carry out tube chamber, down-hole The drill bit assembling is all more quick and easy with the dismounting of ground, top.
