Abstract
The invention provides a mining roof plate absciss layer warning instrument and a measuring method, belonging to the filed of automatic measurement of mine. A mechanical device is mounted on a common anchor rod exposed out of a roof plate to directly replace an anchor rod screw cap and a gasket; the subsidence of the roof plate or the movement of the agsciss layer directly acts on a indicating dial, and the mechanical device transforms the displacement into rotation of a pointer for direct indication; the cup-shaped indicating dial (2) is sleeved outside a roof plate screw cap (1); one end of an irregular spiral steel band (3) penetrates through the cap-shaped indicating dial (2) to be fixed on one end of the roof plate screw cap (1), and the other end is screwed into a measuring handle (5) and penetrates through a pressure spring (4) to be connected with and fixed to a stop block (6) arranged in the measuring handle (5); a pointer (9) is fixed on a pointer seat (8); and the pointer seat (8) is tightly locked on the end part of the measuring handle (5) by a fixing jackscrew (10). The mining roof plate absciss layer warning instrument is mainly used for measurement and early warning of roof plate collapse in a mine and coal mine tunnel and on an extraction coal face.
Description
Technical field
The invention provides a kind of mining roof plate absciss layer warning instrument and measuring method, belong to filed of automatic measurement of mine, be specifically related to measure automatically and intuitively to indicate mine or coal mine roadway and getting working face to crush or the measuring instrument of absciss layer, be mainly used in measurement and early warning that the top board of mine and coal mine roadway and getting working face caves in.
Technical background
At present, at crushing and the monitoring of the presence of absciss layer of mine and colliery, adopt two class measureing equipments and method-force-measuring anchor stock or different types of absciss layer instrument respectively.The former is owing to adopt electronic measuring method, and the pressure that is about to sink converts electronic signal to, realizes status detection, its complex structure, and the processing cost height is difficult for promoting.The latter adopts mechanical type to measure, though it is simple in structure, but range is little, and measuring point obtains difficulty, its modified, also must in roof hole, place special steel wire, and be aided with special-purpose measuring mechanism, and the monitoring of ability completion status, only engineers and technicians and the administrative staff for specialty provide data, same concerning vast miner, also there is inconvenience.
Summary of the invention
The objective of the invention is to: for avoiding above-mentioned defective, provide a kind of mining roof plate sinking absciss layer warning instrument and original measuring method, make the miner of underground work on and off duty through out-of-date, can see whether top board is stable in every day.In case the top board displacement reaches dangerous degree, this degree is showed at once intuitively, and miner and Security Officer will organize and withdraw, thereby reach the purpose of early warning.Its frame for movement is simple, and reliable operation is easy for installation, flexible, wide accommodation.
The present invention for realizing the technical scheme that its purpose provides is:
A kind of mining roof plate absciss layer warning instrument and measuring method, mechanical device is installed on the common bolt that exposes top board, directly replace anchor pole nut and pad, the sinking or the mobile of absciss layer of top board are acted directly on the indicating dial, changing displacement into pointer by mechanical device rotates, and directly indicate, the present invention constitutes like this: cup-shaped indicating dial (2) is enclosed within the outside of top board nut (1), one end of special-shaped helical steel band (3) passes the center hole of cup-shaped indicating dial (2), be fixed in an end of top board nut (1), the other end screws in the inside of measuring handle (5) from the bar hole of measurement handle (5) end that is with hand rest (8), passing compression spring (4) measures the inner block (6) of handle (5) and links to each other and interfix with putting into, sealing end cap (7) is buckled in the other end of measuring handle (5), pointer (9) is fixed on the hand rest (8), and fixedly jackscrew (10) lock onto hand rest (8) end of measuring handle (5).
The present invention is compared with prior art: it is rational in infrastructure, installs simply, easy to maintenance, has the early warning deixis directly perceived of automatic measurement and wide range, to crushing and the displacement measurement of absciss layer is accurate, precision is high.The infield flexible and selectable effectively prevents entering of dust, also can guarantee the work of carrying out reliably and with long-term under the situation of environment very severe.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is a longitudinal profile constructional drawing of the present invention.
Fig. 2 is a schematic top plan view of the present invention.
Among the figure: 1, top board nut, 2, cup-shaped indicating dial, 3, special-shaped helical steel band, 4, compression spring, 5, measure handle, 6, block, 7, the sealing end cap, 8, hand rest, 9, pointer, 10, fixing jackscrew, 11, reflective indication film
The specific embodiment
The embodiment of the invention mainly by: top board nut (1), cup-shaped indicating dial (2), special-shaped helical steel band (3), compression spring (4), measure handle (5), block (6), sealing end cap (7), hand rest (8), pointer (9), fixing jackscrew (10), reflective indication film parts such as (11) composition.It is characterized in that: cup-shaped indicating dial (2) is enclosed within the outside of top board nut (1), one end of abnormity helical steel band (3) passes the center hole of cup-shaped indicating dial (2), be fixed in an end of top board nut (1), the other end screws in the inside of measuring handle (5) from the bar hole of measurement handle (5) end that is with hand rest (8), passing compression spring (4) measures the inner block (6) of handle (5) and links to each other and interfix with putting into, sealing end cap (7) is buckled in the other end of measuring handle (5), pointer (9) is fixed on the hand rest (8), and fixedly jackscrew (10) lock onto hand rest (8) end of measuring handle (5); Its feature also is: be evenly equipped with the numeral of hollow out on the cup-shaped indicating dial (2) and paste the reflective indication film (11) that is printed on meticulous scale, top board nut (1) can only endwisely slip in cup-shaped indicating dial (2) with respect to cup-shaped indicating dial (2), can not radially rotate, hand rest (8) can 360 ° of location with respect to measuring handle (5).
During installation, the length of exposing top board according to anchor pole, wheel measuring handle (5), top board nut (1) is linked to each other and relative fixed with anchor pole, measure the cup-shaped bottom that handle (5) is pressed on cup-shaped indicating dial (2) this moment under the effect of compression spring (4), cup-shaped indicating dial (2) then is pressed on the top board, adjust hand rest (8), make pointer (9) point to hollow out numeral 0, and the jackscrew that is tightened (10).
When crushing or during absciss layer, cup-shaped indicating dial (2) is under pressure and the effect of displacement, promoting to measure handle (5) rotates along special-shaped helical steel band (3), displacement signal is converted to the rotation of pointer (9), point to the different scales of cup-shaped indicating dial (2), thereby finish the function of automatic measurement and early warning indication.Cup-shaped indicating dial (2) is gone up uniform hollow out numeral and is had the effect that prevents dust covering scale.
