Embodiment
Understand better essence of the present invention for convenience of those of ordinary skill in the art, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Embodiment mono-
As shown in Figure 1, a kind of mechanical type counting assembly that measures the rock drilling equipment accumulative total rock drilling degree of depth, comprising: synchronous counting wheel 1, single-chip microcomputer 2, pressure switch 3 and register 4.Described synchronous counting wheel 1 tumbler 11 by band signal source and induction pieces 12 form, and described tumbler 11 is connected with the output shaft of rock drilling equipment oil motor, and described induction pieces 12 is connected with single-chip microcomputer 2; Described pressure switch 3 is arranged on the hydraulic cylinder of oil motor and is connected with single-chip microcomputer 2 signals; Described register 4 is connected with single-chip microcomputer signal, is used for showing the accumulative total rock drilling degree of depth.
In the present embodiment, the feed motion of rock drilling equipment drives chain to realize by oil motor, and tumbler 11 is directly fixing with the output shaft of oil motor, is used for the number of turns of direct-detection oil motor rotation, is converted into jackdrill feeding depth.
Preferably, described tumbler 11 is for being directly fixed on the rotating disk in oil motor rotating shaft.Described signal source is the induced magnet being arranged on rotating disk 11.Described induction pieces 12 is four magnetic induction switches, and four magnetic induction switches are evenly distributed on concentric circles the concentric circles girth quartern.
Particularly, the mounting structure of described tumbler 11 and induction pieces 12 is: prepare one with the circular metal plate of the concentric same diameter of rotating disk, at 4 φ 12 mounting holes of round metal twist drill, 4 holes require be distributed on the circumference of rotating disk signal source with diameter on, be used for fixing 4 magnetic induction switches.When dial rotation, induced magnet one by one inswept 4 magnetic induction switches sends signal.
For ensureing the steady operation of single-chip microcomputer, improve the antijamming capability of input, output signal, as shown in Figure 2, between single-chip microcomputer and induction pieces, be connected by optocoupler 5 between single-chip microcomputer and pressure switch.Further, on register 4, be provided with relay indicating light, count pulse pilot lamp and register output indicator, be connected by optocoupler 6 between register and single-chip microcomputer.
When real work, reach the long object of meter by the rotating cycle of statistics tumbler 11; Whether the action of pressure switch 3, just in time reflects the real-time working state of hydraulic gate, and as the hollow travel stage in jackdrill ascent stage and decline, pressure switch 3 can not move, and at this moment, just do not count; While only having phase of boring, hydraulic cylinder oil pocket pressure rise, the actuating of relay, just counting.
The concrete counting principle of magnetic induction switch is: four magnetic induction switches are divided into two groups, and first group is respectively " estimating 1 ", " counting 1 ", and second component is not " estimating 2 ", " counting 2 ".In the time that pre-flowmeter sensor collects signal, single-chip microcomputer is " 1 " preservation by the status indication of pre-flowmeter sensor, and in the time that sensor for countering collects signal, single-chip microcomputer is the flag state of the corresponding pre-flowmeter sensor of inquiry automatically; If estimate accordingly, sensor mark state is for " 1 ", and single-chip microcomputer counting adds 1, and by the flag state of all pre-flowmeter sensors clear " 0 "; If estimate accordingly, sensor mark state is for " 0 ", and single-chip microcomputer is not counted, and by the flag state of all pre-flowmeter sensors clear " 0 ".The benefit of doing is like this, not only eliminated the impact of operational vibration on counting, counting accurately, and counting while effectively preventing from reversing.
As shown in Figure 4, in the present embodiment, the diameter of rotating disk is preferably 100mm, and the minimum controlled quentity controlled variable of demonstration numeral of register is preferably 0.1 meter.Like this, the girth that turntable rotation one encloses is 314mm, turns 1 circle and sends 2 count pulses, that is, 1 pulse represents to cut a hole into 157mm, closes 0.157 meter.Register should be walked step number and round for (overall pulse number × pulse equivalency)/100, and wherein, the unit of pulse equivalency is mm/p.Shut down for avoiding having a power failure the loss of data that produces 0.1 meter, in the time that remainder is between 0.05～0.099 meter, first walk 1 step more, as: single-chip microcomputer is received the 1st count pulse, 0.157 meter of overall length, and first control step motor is walked 2 steps; Receive the 2nd count pulse, 0.314 meter of overall length, total step number is 3, and the total step number of walking is above 2, so 1 step of only need going further; Receive the 3rd count pulse, 0.471 meter of overall length, total step number is 5, and the total step number of walking is above 3, so 2 steps of only need going further; By that analogy.In actual count process, for preventing cumulative errors, adopt absolute data processing, that is, the effective count pulse sum of whole accumulative totals since rock drilling equipment operation, be multiplied by length pulse equivalency, draw total Excavation Length; Then according to total length, calculate the register step number that export control, and round up, like this, just can make final absolute Measurement error be controlled in 0.05 meter.Data are kept in the ROM in single-chip microcomputer for a long time, and not being subject to have a power failure affects.
As the one equivalence embodiment of the present embodiment, magnetic induction switch also can change six into, divides three groups, and seemingly, the pulse equivalency that is each pulse becomes 104.7mm for counting principle and two categories; Counting process repeats no more here in detail.
Embodiment bis-
A mechanical type counting assembly that measures the rock drilling equipment accumulative total rock drilling degree of depth, comprising: synchronous counting wheel, single-chip microcomputer, pressure switch and register.Described synchronous counting wheel is made up of tumbler and the induction pieces in band signal source, and described tumbler is connected with the output shaft of rock drilling equipment oil motor, and described induction pieces is connected with single-chip microcomputer; Described pressure switch is arranged on the hydraulic cylinder of oil motor and is connected with single-chip microcomputer signal; Described register is connected with single-chip microcomputer signal, is used for showing the accumulative total rock drilling degree of depth.
Mechanical type counting assembly and embodiment mono-that the present embodiment provides are basically identical, and difference is:
One, the feed motion of rock drilling equipment drives chain to realize by Hydraulic Cylinder pulley, and because diameter of pulley is larger, turning around, it is oversize to be converted into rock drilling equipment feeding depth; To this, the rotating disk that is 70mm by diameter is fixed on big gun beam, center dress bearing, and periphery cover steel cable, steel cable is around hydraulic rock drilling equipment and guide rail one week, and uses spring straining.Fricton-tight for ensureing between rotating disk and steel cable, aluminium or nylon for rotating disk material.
