Description
Technical field
The utility model relates to a kind of drilling rod locating guide device, belongs to mine equipment, particularly relates to the servicing unit that a kind of electric drilling machine creeps into.
Background technology
In the operation of colliery, usually use colliery hydraulic tunnel drilling machine to creep into engineering hole that coal mine gas takes out (row) discharge hole, fluid injection fire-fighting hole, coal-bed flooding hole, protrusion-dispelling pressure relief vent, geological prospecting hole and other major diameter, long distance.Because drillable length is longer, coal or rock stratum soft durometer skewness, drilling rod deadweight is comparatively large in addition, and the direction in the hole got out usually can be caused to depart from original orientation angle.And in work progress, often there will be the situation departing from excessive and rig overload.At present, yet there are no the comparatively effective technical scheme addressed this problem.
Summary of the invention
The purpose of this utility model is, there is provided a kind of coal mine drilling machine when drillable length is greater than 1.5 meters, a kind of drilling rod locating guide device of beat can not be there is in drill bit, this device is stifled by spike, strut, center, seal cover, drilling rod, axle sleeve, oil, thread sealed closure, oil filler point, the shaft shoulder form, original drilling rod adds location dress guiding device, drilling rod is rotated around the center line in the hole of having bored.Due to the supporting role of drilling rod locating guide device of the present utility model, drill bit cantilever shortens, if when running into softer or harder coal or rock stratum, beat can significantly reduce.Simultaneously install drilling rod locating guide device additional every a segment distance, solve drilling rod and to conduct oneself with dignity the distortion caused.Can guarantee under the prerequisite of not disalignment, the length of boring significantly to be increased.
A kind of drilling rod locating guide device of the present utility model, this device is by spike, strut, center, seal cover, drilling rod, axle sleeve, oil is stifled, thread sealed closure, oil filler point, the shaft shoulder forms, in drilling rod (5) upper end fixed center cover (3), strut (2) is fixed in the upper end of center (3), spike (1) is fixed on the top of strut (2), seal cover (4) is packaged with in the side of center (3), opposite side is packaged with thread sealed closure (8), axle sleeve (6) is provided with between center (3) and drilling rod (5), center (3) has oil filler point (9), stifled (7) the shutoff oil filler point (9) of oil, internal thread is had at the endoporus of thread sealed closure (8), correspondence position on drilling rod (5) has external screw thread, by the shaft shoulder (10), thread sealed closure (8) and drilling rod (5) are fixed.
Seal cover (4), to be sealed by labyrinth seal structure between thread sealed closure (8) and center (3), and leave gap.
Being over-surplus fit structure between axle sleeve (6) and drilling rod (5), is matched in clearance structure between axle sleeve (6) and center (3).

Detailed description of the invention
Further illustrate below in conjunction with accompanying drawing, and provide embodiment:
A kind of drilling rod locating guide device of the present utility model, this device is by spike, strut, center, seal cover, drilling rod, axle sleeve, oil is stifled, thread sealed closure, oil filler point, the shaft shoulder forms, at drilling rod 5 upper end fixed center cover 3, strut 2 is fixed in the upper end of center 3, spike 1 is fixed on the top of strut 2, seal cover 4 is packaged with in the side of center 3, seal cover 4, sealed by labyrinth seal structure between thread sealed closure 8 and center 3, and leave gap, opposite side is packaged with thread sealed closure 8, axle sleeve 6 is provided with between center 3 and drilling rod 5, it is over-surplus fit structure between axle sleeve 6 and drilling rod 5, it is matched in clearance structure between axle sleeve 6 and center 3, center 3 has oil filler point 9, the stifled 7 shutoff oil filler points 9 of oil, internal thread is had at the endoporus of thread sealed closure 8, correspondence position on drilling rod 5 has external screw thread, by the shaft shoulder 10, thread sealed closure 8 and drilling rod 5 are fixed,
As shown in Figure 1, 2, described a kind of drilling rod locating guide device, the metal material of its each parts high strength makes, and center 3, strut 2 and spike 1 is fixed as a whole bracing or strutting arrangement, is set on drilling rod 5; For guarantee drilling rod 5 rotate while the asynchronous rotation of bracing or strutting arrangement, at the both sides of center 3 difference potting lid 4 and thread sealed closure 8, and axle sleeve 6 is encapsulated between center 3 and drilling rod 5, the seal cover of both sides and center 3 adopt labyrinth seal structure to seal, sealing lubrication oil and ensure that it does not run off, is interference fit between axle sleeve 6 and drilling rod 5; It is matched in clearance between axle sleeve 6 and center 3, the object adopting said structure can realize being mounted on the center 3 on drilling rod 5 simultaneously can not to rotate with drilling rod 5, the length of strut 2 can be for you to choose according to the diameter customization plurality of specifications of boring, spike 1 for following drilling rod 2 synchronizing moving forward by the support of this device on the hole wall got out, and the frictional resistance between itself and drill hole wall can keep this device can not rotate with drilling rod 2;
As shown in Figure 2, the external screw thread that the internal thread that the inner side of thread sealed closure 8 is opened and drilling rod 5 are opened coincide mutually, by rotate withstood on drilling rod 5 the shaft shoulder 10 on and tighten, lubrication oil can be injected among the gap of above-mentioned each part fits by the oil filler point 9 that center 3 is opened, guarantee that it is on-streamly lubricated fully, to reduce friction resistance and do not affect the drilling efficiency of rig;
Before creeping into, this device of dimension is selected according to the diameter of boring, to be set on drilling rod 5 and to be tightened fixing, by oil filler point 9, lubrication oil is injected, with stifled 7 shutoff of oil, because center 3 and axle sleeve 6 are matched in clearance, and both sides sealing lid to be fixed on drilling rod 5 and to have certain gap with center 3, make drilling rod 5 while swivel feeding forward, center 3 with drilling rod 5 march forward to, but rotate because frictional resistance makes center 3 can not follow drilling rod 5, thus can be the support that drilling rod 5 provides stable, guarantee that drilling rod 5 directly moves ahead along drill center wire diameter, play the effect that guiding and location are provided in drilling rod 5 feeding process.
