Abstract
The utility model relates to an instrument which is particular suitable for the quick and direct measurement of the coal intensity of the underground mining site of a coal mine. The utility model is characterized in that a shaft-shaped push force reading ruler and a depth reading ruler are both provided with zero position regulating devices, the precision of the shaft-shaped push force reading ruler is 0.5 mm, and the precision of the depth reading ruler is 0.1 mm. The utility model has the advantage of good consistency, dismountable function and portability; in addition, the utility model is applicable to each measuring point of different coal mines and identical coal mine.
Description
The utility model is a kind of determinator of trying out on-the-spot direct and quick determination coal intensity under coal mine especially.
Measure the method for coal intensity at present, many employing weighted-drops are to send the laboratory under the coal mine behind the spot sampling, screen, smash to pieces, impact, sieve the powder operation through precision, pack into and obtain experimental data in the metering cylinder and by formula calculate coal mass strength again, the resultant error of measurement is big, efficient is low, labour intensity is big; Existing analyzer is read the position device that do not return to zero on the chi at vernier, and part-structure adopts and is slidingly matched, and still can not improve precision, and be not easy to carry.
The purpose of this utility model be to develop a kind of can be under coal mine the produce coal analyzer of intensity of on-the-spot directly rapid test.
Analyzer is seen accompanying drawing 1, comprise standard examination awl (1), circular examination awl seat (2), normal pressure spring (3), spring base (4), axle shape thrust is read chi (5), end cap (6), sliding sleeve (7), tubular shell (8), the degree of depth is read chi (9), standard examination awl (1) external thread is fastened in circular examination awl seat (2) screwed hole of centre, its external thread and tubular shell (8) are fastening, tubular shell (8) the inside normal pressure spring (3) of packing into, spring base (4) center is fitted on the normal pressure spring (3) end cap (6) external thread and the fastening formation one of tubular shell (8); Axle shape thrust reads to be equipped with on the chi (5) indicating ring (10), and axle shape thrust is read central axis place, chi (5) lower end riveting dress fixing pin (11), and its upper end and round handle (12) link.End cap (6) center pit bottom surface has the groove and the blind groove of symmetry and sees accompanying drawing (4), and axle shape thrust is read chi (5) and passed end cap (6) center pit and groove, utilizes fixing pin (11) to snap in the blind groove of end cap (6) bottom surface, makes its locking.The most outstanding characteristics of the utility model are that the screwed hole of centre at spring base (4) is equipped with zeroing position screw (12) and set nut (13) and axle shape thrust and reads chi (a 5) lower end surface and zeroing screw (a 12) end face apical grafting, upper and lower adjusting zeroing position screw (12) makes a shape thrust read chi (5) shift position recovery zero-bit thereupon, has improved the mensuration precision; At circle examination awl seat (2) cylindrical, be drilled with four equal, orthogonal blind holes of straight warp, pack in each blind hole a little compression spring (14) and a steel ball (15), and between sliding sleeve (7) and tubular shell (8) are inserted in the outside of four steel balls (15), form to roll and cooperate.Automatically adjust the concentricity of sliding sleeve (7) and standard examination awl (1), reduced the rigging error of total system; Sliding sleeve (7) cylindrical one side has the rectangle groove and equates with the size that the degree of depth is read horizontal center line axis director's square three-way groove of chi (9), the movable vernier (17) that the L type vernier slide block (16) and the degree of depth are read chi (9) links, being bumped into the degree of depth reads in the rectangle groove of chi (9), L type vernier slide block (16) leptoprosopy center has threaded hole, zeroing position jackscrew (18) is housed, its bottom surface and the vertical apical grafting of circular examination awl seat (2) circumferential plane, when regulating the movable vernier part (16 of zeroing position jackscrew (18), 17), shift position thereupon, the degree of depth are read chi (9) and are reached zero-bit and regulate.
The periphery of circular examination awl seat (2) also has a tapped blind hole, sliding sleeve (7) cylindrical opposite side has " type pilot hole; dog screw (19) passes that " the type pilot hole is fastened in the cylindrical tapped blind hole of circular examination awl seat (2), make sliding sleeve (7) and tubular shell (8) positioning and locking, in case sliding sleeve (7) is deviate from.
Advantage of the present utility model and effect are: one, can under coal mine, directly measure coal mass strength fast in the scene, and the efficient height, labour intensity is little.Two, have consistance to different with each measuring point in identical colliery, improve precision, axle shape thrust is read chi (5) and can be reached 0.5 millimeter, and the degree of depth is read chi (9) can reach 0.1 millimeter.Three, enlarged measurement range, it is the 0-55 millimeter that axle shape thrust is read chi (5), and the degree of depth is read chi (9) and is 0-200 newton.Four, have detachably, and be easy to carry the advantage that cost is low.
