Description
Technical field:
The invention belongs to mining engineering technical field, be specifically related to a kind of dredging treating apparatus blocking big gun hole.
Background technology:
Carry out in underground ore bodies recovery process at application drilling and blasting method, the construction quality in big gun hole determines the complexity of follow-up charging work and the effect of final explosion.Due to the impact of mine fragmentation and adjacent shot hole blast action, cause the big gun hole of constructing complete that crag occurs often and peel off and cause multiple-row blasting, this situation especially under high stress or the joint of ore deposit rock own, cranny development region particularly evident.If carry out dredging process to blocking big gun hole not in time, in follow-up powder charge work progress, easily there is explosive payload deficiency and Charge distribution non-uniform phenomenon, the problem such as cause design explosion position not pop and quick-fried heap boulder yield is high, the work for the treatment of in not quick-fried region is carried out under barnyard, there is huge potential safety hazard, meanwhile, the secondary blasting of bulk adds final cost of winning.
The settling mode of multiple-row blasting problem comprises perforations adding and dredging process two kinds.Original position perforations adding constructional difficulties, cannot ensure that perforations adding position overlaps with big gun hole of constructing, and generally, carries out perforations adding, perforations adding process is time-consuming near blocking big gun hole, effort, and perforations adding position is departed from design big gun hole site, affects final demolition effect.In actual mine construction, mainly process blocking big gun hole by big gun hole dredging means.Usual method utilizes tamper or pencil, dredging operation is carried out by the mode of manpower push rod, the impact strength of operating personnel is depended in its success or failure, because manpower limit, add the reasons such as hole wall frictional force is larger, cause artificial dredging mode inefficiency, artificial through hole is applicable to the dredging blocking not serious big gun hole, and block closely knit big gun hole be difficult to process by the method.Another kind method is by drilling equipments such as electric picks, dredge blockage big gun hole is come by the rotation of lengthening drill bit and percussion, this method power source is placed in hole outside, along with the increasing of plug depth, being short of power easily appears in the rotation of lengthening drill bit and percussion, add the impact of lengthening drill bit dead weight, so that this method is only applicable to process plug depth and is less than the big gun hole of 2m.The dredging processing method entirety in current blocking big gun hole exists that labour intensity is large, Mechanization Level is low, the inferior shortcoming of very flexible, inefficiency.
Summary of the invention:
For solving prior art Problems existing, the present invention proposes that a kind of structure is simple, easy to carry, flexible operation and the dredging treating apparatus in the blocking big gun hole of successful.For achieving the above object, the present invention adopts following technical scheme:
Block the dredging treating apparatus in big gun hole, comprise body and extension bar, extension bar is arranged on body rear end, and the front end of body is provided with the bore bit that can stretch, and is provided with motor in body, the axle of described motor and bore bit interlock.
The axle of described motor is provided with travelling gear, change-speed gearing is provided with in body, described travelling gear and change-speed gearing are bevel gear and engage each other, and the eccentric position of change-speed gearing is connected with by power transmission shaft the lower end of drive link, and the upper end of drive link is connected to bore bit.
Piston cylinder is provided with in described body, the upper end of drive link is provided with piston, described piston is arranged on the bottom in piston cylinder, top in piston cylinder is provided with pricker groove, gap is left between pricker groove and piston cylinder, be provided with spring between pricker groove and bore bit rear end, be provided with in the piston cylinder between pricker groove and piston to impact and fill in.
The front end of described body is provided with card pricker device, and bore bit correspondence position is provided with groove.
Beneficial effect of the present invention: reduce the cost of perforations adding and dredging and the labour intensity of workman, impulsive force is sufficient, be easy to carry and use.

Detailed description of the invention:
Below in conjunction with drawings and Examples, the present invention is described in further details: as shown in Figure 1 to 4, block the dredging treating apparatus in big gun hole, comprise body 15 and extension bar 16, extension bar 16 is arranged on body 15 rear end, for multistage syndeton, extension bar 16 can be extended easily.The front end of body 15 is provided with the bore bit 1 that can stretch, motor 3 is provided with in body, the axle of described motor 3 and bore bit 1 are by speed change gear and cylinder-driven mechanism interlock, the change-speed gearing 7 that described speed change gear comprises the travelling gear 9 on the axle of motor 3 and arranges in body 15, described travelling gear 9 is bevel gear with change-speed gearing 7 and engages each other, and the eccentric position of change-speed gearing 7 is connected with by power transmission shaft 19 lower end of drive link 8.Described cylinder-driven mechanism comprises the piston cylinder 2 be arranged in body 15, the upper end of drive link 8 is provided with piston 6, described piston 6 is arranged on the bottom in piston cylinder 2, top in piston cylinder 2 is provided with pricker groove 5, the gap for ventilating is had between pricker groove 5 and piston cylinder 2, be provided with spring 14 between pricker groove 5 and bore bit 1 rear end, be provided with in the piston cylinder 2 between pricker groove 5 and piston 6 and impact plug 4.Body 15 front end is provided with card pricker device 11, and the correspondence position on bore bit 1 is provided with groove, for coordinating card pricker device 11, ensures that bore bit 1 moves in OK range.
When the big gun hole in rock mass 12 is clogging by rubble 13, when being difficult to suitable explosive, the body 15 of device of the present invention is connected with extension bar 16, many extension bars 16 are connected to appropriate length, the lower end of extension bar 16 connects the handle 17 for grasping, the electric wire 10 of motor 3 internally extends from extension bar 16, and arranges switch 18 on electric wire 10.Body 15 is stretched in the big gun hole of rock mass 12 by extension bar 16, after bore bit 1 touches rubble 13, open switch 18, the axle of motor 3 starts to rotate, band nutating gear 9 rotates, travelling gear 9 drives change-speed gearing 7 to rotate, piston 6 is driven to move by drive link 8 again, piston 6 transmits momentum to pricker groove 5 by the impact plug 4 in piston cylinder 2, and then make bore bit 1 impact rubble 13, under ceaselessly impacting, the rubble 13 in big gun hole can drop out in big gun hole, thus completes the process of once dredging and clearing up.
Bore bit 1 can be set to different shapes, as yi word pattern, cross and scratch type, for clearing up the big gun hole of different situations.
