Description
Technical field
The utility model belongs to drilling rig technique field, is specifically related to a kind of colliery light hydraulic rig.
Background technology
Along with the further exploitation of coal in China, balk, compose that to deposit the feature such as dark day by day obvious, coal resources in China distributional region otherness in addition, causes gas exhaust problem to become increasingly conspicuous.Gas drainage drilling rig is mainly used in underground coal mine and bores the holes, down-hole such as gas exhaust discharge hole, protrusion-dispelling pressure relief vent, coal-bed flooding hole.At present, be applied to the all-hydraulic drill in middle small bore gas drainage under suction tunnel primarily of the most of composition of pumping plant, main frame, column frame and console etc. four, wherein main frame comprises unit head, pallet arrangement, frame, water pigtail, hydraulic gripper etc.During operation, pumping plant, console and column frame are placed on the ground, frame is fixed on column frame, unit head is spacing in frame by supporting plate, and supporting plate forms the support guide mechanism of unit head together with frame, and the output shaft of unit head is connected power transmission on drilling rod with hydraulic pressure pipe slips and water pigtail, connected by screw thread between drilling rod, hydraulic gripper is installed in the front end of frame, and clamp drilling rod and lead, rig creeps into operation by having vertically moved.Also there is following defect and deficiency in this rig:
1, the host machine integral complex structure of rig, is not easy to install; Reliability is low, and maintenance load is large, affects operating efficiency; Volume is large, and weight is large, is not easy to carry and carry; Waste time and energy when rig being disintegrated and assembles, have a strong impact on operating efficiency;
2, drill power head part position-limit mechanism structure is too complicated, by supporting plate by spacing for unit head on the guide rail of frame, between supporting plate and guide rail, be provided with again the part such as middle base, copper coin simultaneously, not only add the weight of complete machine, and have impact on the positioning precision of boring, reduce the drilling efficiency of rig; Guide rail structure is the U-lag steel of opening to the right, and it is arranged symmetrically in frame, and the shortcoming of this structure in use easily elastic deformation occurs, guiding accuracy is deteriorated, adds the vibration of rig, even can cause fractureing of drilling rod, cause the accident, have impact on operating efficiency;
3, rig completes by propelling cylinder and unit head collaborative work the task of creeping into, propelling cylinder piston rod is fixed on supporting plate, hydraulic thrust acts on drilling rod by supporting plate, this structure causes hydraulic thrust excessive with the spacing of boring resistance, produce great role force couple role thus on supporting plate, cause supporting plate generation elastic bending deflection, and then affect the guiding accuracy of unit head, even drilling rod can be fractureed; The power transmission mechanism complex structure of rig, power input shaft is connected in slips hollow shaft by key, slips hollow shaft by slips by power transmission on the drilling rod in slips hollow shaft, power transmission efficiency is low, and whole length is longer;
4, the all-hydraulic clamp system complex structure of slips, sealing requirements are high, and in real work, sealing ring easily causes losing efficacy under the strong vibration effect of drilling process, thus diminishes to the clamping force of drilling rod; And, clamping slips do not lubricate and expose, rig is when elevation angle operation, and the impurity such as mud, coal dust can be stuck in the shifting chute of slips, cause the clamping of drilling rod, unclamp be difficult to realize, affect operating efficiency;
5, slips is complete enclosed construction, inner at slips, power from power head is delivered to drilling rod by being threaded of rigidity by power head output shaft, in drilling process, the gummed that is threaded is caused because misoperation or geology change can produce great moment of torsion, make drilling rod not quick detachable, even make output shaft twist off at connection of thread, be stuck in slips inside and be difficult to get and remove;
6, due to water swivel axis rotation at a high speed and the vibration of radial direction, often cause the ring wear between housing and water swivel axis or conquassation, sealing ring is short for application life, needs frequently to change, if change not in time, can cause leaking, and easily cause the damage to water swivel axis, and after water swivel axis damage, replacing trouble, cost are high, replacing sealing ring and water swivel axis affect construction speed, and bring impact to the safety in production of user.
7, hydraulic gripper is that equilateral triangle is arranged and welded together and forms by three block plates, and in order to ensure the precision of creeping into, what three block plates must be strict is mutually 60 °, but is difficult to ensure in the welding process of reality; And because whole support is welded construction, long-time vibration and hydraulic pressure reverse active force can cause weld to ftracture; In addition, by the impact of welding support, change is freeed in the cover plate pilot hole position be fixed on support; Under above factor effect, cause the slips center of clamper and drill power head center inconsistent, the drilling rod of interpolation and the drilling rod center of clamp holder clamping inconsistent, cause centering difficulty, the destruction that is threaded between drilling rod, the vibration of rig increases, and drilling rod even can be made to fracture.
