Abstract
The utility model discloses a coal mine drilling and hole penetrating device which is characterized by comprising a sleeve (1), a U-shaped ring (2) is welded on the top of the side wall of the sleeve (1), and a pulley (3) is welded on the side wall of the outer circumference of the sleeve (1). Two pull wires (4) penetrate into the pulley (3), and the two ends of each pull wire are connected with a snap ring (5) and a handle (6) respectively. The coal mine drilling and hole penetrating device not only can improve work safety, but also can relive labor intensity of work, and drilling and hole penetrating efficiency is improved.
Description
Technical field
The utility model relates to a kind of coal mine drilling construction equipment, relates in particular to a kind of coal mine drilling hole penetrating device.
Background technology
Spray orifice phenomenon in various degree all appears in the coal mine drilling work progress, can spray a large amount of coal dusts during the boring spray orifice, after spray orifice, coal body is loose, coal body slump in later stage extraction process mesopore, cause the boring plug-hole, secondly long-term high negative pressure extraction also can cause coal body collapse hole in boring, causes boring to be stopped up, and has a strong impact on extracting result.
Process feeler lever with the galvanized iron conduit of diameter 15mm at present, every feeler lever 1.5m, two processed filament mouth connects with the joint hoop.Manually once descend feeler lever in hand-hole; Until lower to boring obstruction place; Utilize feeler lever in the reciprocal stirring of boring obstruction place; The boring of stopping up is led to thoroughly; But the weight of feeler lever own adds the impact with borehole wall frictional resistance; Cause the open-work degree of depth limited; Only plug depth is not more than the boring of 15m thoroughly; And be that manpower is upwards lifted during open-work; Personnel stand on the below, aperture; Stir back and forth feeler lever; Labour intensity is large; Efficient is low; Be difficult for thoroughly logical to stopping up serious boring; And the coal in open-work process mesopore; The rock dust piece can directly drop to it the workman; Continuous increase along with the open-work degree of depth; Easily causing feeler lever to disconnect hurts sb.'s feelings.
The utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly can improves operational security, alleviates operation labor intensity, improves the coal mine drilling hole penetrating device of boring open-work efficient.
A kind of coal mine drilling hole penetrating device is characterized in that: comprise sleeve, in the sleeve lateral wall welded top, U-loop is arranged, be welded with pulley on sleeve excircle sidewall, penetrate two draught lines from pulley, the two ends of draught line are Joining clasp and handle respectively.
Compared with prior art, the beneficial effect that the utlity model has is:
1, owing on the utility model sleeve, pulley being housed, can use draught line that feeler lever is delivered in the hole, realize long apart from operation, this faces the aperture when just having been avoided open-work, greatly reduce open-work Coal During piece and feeler lever and disconnect to drop in the hole and hurt sb.'s feelings, the safety when greatly having improved operation.
2, because the utility model can be by the traction of draught line line, in the process of continued access feeler lever in the hole, draught line can be fixed on after tunnel section of side anchor pole on other positions, alleviated the amount of labour that feeler lever limit continued access feeler lever is lifted on the limit, when pulling draught line to send feeler lever in the hole, because of draught line longer, the space is open, many people together pull simultaneously, have therefore alleviated workman's operation labor intensity, have improved boring open-work efficient.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of coal mine drilling hole penetrating device of the utility model.
The specific embodiment
As shown in Figure 1, a kind of coal mine drilling hole penetrating device comprises sleeve 1, be welded with U-loop 2 in sleeve 1 top side wall, be welded with pulley 3 on sleeve 1 excircle sidewall, penetrate two draught lines 4 from pulley 3, the two ends of draught line 4 are Joining clasp 5 and handle 6 respectively.
During open-work, sleeve 1 is passed drill hole pipe 7, U-loop 2 is suspended on the bolt 8 that is welded in drill hole pipe 7 sidewalls, be stuck in feeler lever 9 ends on snap ring 5 and after fixing, pull a draught line 4, feeler lever 9 is sent in the hole, then realize continued access feeler lever 9 by two covering device alternately operatings, feeler lever 9 ends that newly connect are stuck in another card 5 rings equally, pull another root draught line 4.Intersect like this and draw, until feeler lever 9 is delivered to boring obstruction place, make and visit the back and forth stirring in boring of 9 bars, until it is logical to hole.
A kind of coal mine drilling hole penetrating device of the utility model can not only improve operational security, and alleviate operation labor intensity, improves boring open-work efficient.
