Abstract
The utility model relates to a pneumatic down-hole hammer drilling device, in particular to a down-hole hammer wind-pressure drilling device for drilling in ripped-rock layers and gravel sand layers. The pneumatic down-hole hammer wind-pressure drilling device is characterized in that a wear-resisting cannula is sleeved outside a drill rod, a connecting disc is arranged between the wear-resisting cannula and the drill rod, and two ends of the wear-resisting cannula are provided with connecting receivers. A round disc for fixedly connecting is arranged between the central portion of the wear-resisting cannula and the drill rod, a connecting receiver on the upper port of the wear-resisting cannula is connected with the drill rod through a sealing disc to form a compound drill rod for improving wind speed in the drill hole. Or connecting discs are respectively arranged between the upper portion and the lower portion of the wearing-resisting cannula and the drill rod as a fixed supporting stand of a wearing-resisting cannula to form a powder dredging pipe. The pneumatic down-hole hammer drilling device can timely remove rock powder, detritus and gravel stone in the drill hole through improving wind speed in the drill hole and adding the power dredging pipe, and greatly improves the drilling efficiency.
Description
Technical field
The utility model relates to the pneumatic down-hole hammer drilling apparatus, particularly a kind of wind pressure drilling device of pneumatic down-hole hammer that creeps at macadam and sand pebble layer.
Background technology
At present at pneumatic down-hole hammer, П-130 pneumatic down-hole hammer (drilling tool diameter 110mm particularly, bore diameter 130mm) in the drilling method, generally all use air compressor machine as driving arrangement, air compressor machine to give air quantity and wind pressure of work be definite value, increase with drilling depth, the rock dust that produces when down-the-hole hammer drill advances, landwaste and gravel can not in time be discharged boring, are suspended in the boring, when stopping to wind, a large amount of rock dust, landwaste and gravel buildup are at foot of hole, bury drilling tool, can't increase drilling rod and continue to creep into, when especially running into sand pebble layer and macadam, this situation is more serious, and drilling efficiency reduces greatly.
Summary of the invention
The purpose of this utility model provide a kind of can improve drilling efficiency, help rock dust, landwaste and gravel to discharge wind pressure drilling device of pneumatic down-hole hammer,
The purpose of this utility model realizes by following technical proposals.
Wind pressure drilling device of pneumatic down-hole hammer of the present utility model, comprise drilling rod, it is characterized in that wear-resistant sleeve of suit outside described drilling rod, between this wear-resistant sleeve and described drilling rod, be provided with clutch disk, be provided with the connection catcher at the two ends of this wear-resistant sleeve, the connection catcher at lower port place connects the taper closed section.
Be provided with a clutch disk between the middle part of described wear-resistant sleeve and described drilling rod, the connection catcher at the upper port place of described wear-resistant sleeve connects one and seals disk, forms the compound drilling rod that improves wind speed in the boring.
Between top, bottom and the described drilling rod of described wear-resistant sleeve, respectively be provided with the fixed support of fixedly connected disk, form and drag for tube cell, drag for the powder chamber in the upside formation of last clutch disk as wear-resistant sleeve.
When the diameter of described drilling rod was 50mm, it was that 3-5mm, diameter are the wear-resistant sleeve of 90mm that described wear-resistant sleeve is selected thickness for use.
Wind pressure drilling device of pneumatic down-hole hammer of the present utility model, improve the operating principle of air flow system in the boring: according to formula Q=F/S, wherein: Q-pressure, F-pressure, the S-lifting surface area, when air compressor machine wind pressure of work (Q) fixedly the time, increase wind-force (F) in the boring, interior lifting surface area (S) need reduce to hole.Because of the boring sectional area is fixed, thus can reduce lifting surface area in the hole (S) by increasing the drilling rod sectional area, thus realize increasing the purpose of wind-force raising wind speed in the hole.The utility model is the purpose that increases the drilling rod sectional area outside needed former drilling rod by the mode of the wear-resistant sleeve that is welded, the compound drilling rod that will improve the interior wind speed of boring during construction is lowered in the boring continuously and creeps into, owing to improved wind speed, increased wind-force in the hole, just help rock dust, landwaste and gravel to discharge pneumatic down-hole hammer, rock dust, landwaste and gravel can not be deposited in foot of hole, therefore just can not bury drilling tool, thereby can improve drilling efficiency.
The tube cell structure of dragging for of the present utility model is basic identical with the compound drilling rod that improves wind speed in the boring, open-ended just, the rock dust that is produced in the drilling process, landwaste and gravel can be by in its cavitys that falls between wear-resistant sleeve and the drilling rod suitable for reading, when drilling tool is proposed in holing, just the rock dust, landwaste and the gravel that are produced in the drilling process just can be pulled out from boring.The tube cell that drags for of the present utility model can be used with improving the interior air flow system of boring, further improves drilling efficiency.
