Abstract
The utility model discloses a narrow gauge track height difference survey meter, which comprises a gradienter (1), a bracket (2) and a lead screw (5). The gradienter (1) is fixed on the top surface of the bracket (2). A steel magnet (3) is fixedly arranged on one landing leg of the bracket (2), and a scale (4) with outward calibration tails is fixed on the other landing leg of the bracket (2). The calibration zero of the scale is arranged at the bottom surface of the bracket (2). The lead screw (5) which is arranged on the outer side of the scale (4) passes through the bracket (2), and is connected with the bracket through thread. The top end of the lead screw (5) is provided with a handlebar (6). The survey meter measures the height difference of tracks accurately, intuitively, conveniently and quickly, which has the characteristics of low manufacturing cost, and being operated and used conveniently. The survey meter meets the requirement of field use, and can be promoted for safe production of mine enterprises.
Description
Technical field
The utility model relates to a kind of surveying instrument, is specifically related to a kind of instrument of measuring narrow gauge two interorbital differences of height.
Background technology
" safety regulations in coal mine " the 353rd requires mine rail to lay by standard, and main haulage drift track quality meets the difference of height and the segment of curve outer rail of 2 rail surfaces of straight-line segment and increases difference of height back and interior tread face by design, all must not be greater than 5mm.And it is current when laying track or track laying after a period of time, because strata behaviors, pelyte is met water and is easy to pucking, very easily cause of the requirement of rail top face difference of height greater than " safety regulations in coal mine " regulation, it is not steady the operation of this locomotive or mine car to have occurred, excessive to lopsidedness, both track height, article one, track is low, when mine car and locomotive operation to lopsidedness, after two tracks just change, locomotive and mine car are moved vacillates now to the left, now to the right, be easy to slide down, draw and ruin shed, major accidents such as disconnected rope sport car occur, cause heavy economic losses.Current measurement two track differences of height are to use surveyor's staff, but direct reading, can only use the steel tape rough measure, and not reach the requirement that two track differences of height that " safety regulations in coal mine " require are not more than 5mm, have that measurement data is inaccurate, error is big, efficient is low, shortcomings such as many consuming time.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of narrow gauge track difference of height measuring instrument, and its technical scheme of taking is:
This measuring instrument comprises level meter, support and screw mandrel, level meter is fixed on the end face of support, be fixed with magnet steel on one side leg of support, be fixed with scale mark rule outwardly on the opposite side supporting leg, " 0 " scale mark on the rule is positioned at the bottom surface of support, the screw mandrel that is positioned at the rule outside passes support and is threaded with support, and the top of screw mandrel is fixed with handgrip.
By rotating handgrip measuring instrument one end is risen, wait in the level meter 1 bubble to mediate and stop, the length of screw mandrel rotation is reading from the rule directly, and this length is the actual difference of height of two tracks.
This measuring instrument can be measured the difference of height and the segment of curve outer rail of 2 rail surfaces of straight-line segment and increase the difference of height of back and interior tread face by design, and directly from the rule reading, adjusts two rail level end face differences of height according to reading.Reach " safety regulations in coal mine " the 353rd two rail level end face differences of height that require like this and be not more than the requirement of 5mm, avoided track quality inferior and have a strong impact on and produce even the accident that often slides down, damage locomotive and mine car and smash shed, disconnected rope sport car casualty accident.
It is accurately directly perceived, convenient and swift that this measuring instrument is measured the track difference of height, has low, the easy for operation characteristics of production cost, satisfied on-the-spot request for utilization, can promote the use of in the safety in production of bargh.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in the figure, the end face fixing horizontal instrument 1 of support 2, what magnet steel 3 usefulness 309 glue were firm is bonded on support 2 one side legs, rule 4 is fixed on the support 2 opposite side supporting legs, the scale mark of rule 4 outwardly, the spacing of adjacent two scale marks is 0.5mm, and " 0 " scale mark is positioned at the bottom surface of support 2.Screw mandrel 5 is positioned at the outside of rule 4, passes the position of support 2 at screw mandrel 5, welds a M8 nut, screw mandrel 5 is screwed in the nut of welding, makes it realize being threaded with support 2, and handgrip 6 is welded on the top of screw mandrel 5.
When using this measuring instrument to measure difference of height, at first it is positioned between two tracks, the bottom surface load that makes support 2 is on two tracks, support 2 one side legs that are fixed with magnet steel 3 are attached to the inboard of higher orbit, allow magnet steel 3 tightly hold this track, and the support 2 opposite side supporting legs that are fixed with rule 4 are adjusted the reference position of screw mandrel 5 then near lower track, make on horizontal level, align " 0 " scale mark of rule 4 of the bottom of screw mandrel 5, subsequently the stationkeeping of screw mandrel 5 is lived.
Rotate handgrip 6 with the hand horizontal direction, and then screw mandrel 5 rotates in support 2, because be threaded and the invariant position of screw mandrel 5 with support 2, so have a side of rule 4 to rise gradually on the measuring instrument, handgrip 6 stops operating when bubble mediates in level meter 1.This moment, the horizontal level alignment rule 4 indicated scale marks from the bottom of screw mandrel 5 carried out reading, and this reading is the actual difference of height of two rail top face.
Claims (1)
1, a kind of narrow gauge track difference of height measuring instrument, comprise level meter (1), support (2) and screw mandrel (5), it is characterized in that: level meter (1) is fixed on the end face of support (2), be fixed with magnet steel (3) on one side leg of support (2), be fixed with scale mark rule (4) outwardly on the opposite side supporting leg, " 0 " scale mark on the rule (4) is positioned at the bottom surface of support (2), the screw mandrel (5) that is positioned at rule (4) outside passes support (2) and is threaded with support (2), and the top of screw mandrel (5) is fixed with handgrip (6).
