Specific embodiment
More fully understand the essence of the present invention for convenience of those of ordinary skill in the art, below in conjunction with the accompanying drawings to the present invention's
Specific embodiment is described in detail.
Embodiment one
As shown in figure 1, a kind of metering rock drilling equipment adds up the mechanical type counting assembly of rock drilling depth, comprising: synchronous counting
Wheel 1, single-chip microcomputer 2, pressure switch 3 and register 4.Described synchronous counting wheel 1 is by the tumbler 11 in band signal source and induction pieces
12 compositions, described tumbler 11 is connected with the output shaft of rock drilling equipment hydraulic motor, and described induction pieces 12 are connected with single-chip microcomputer 2；
Described pressure switch 3 is arranged on the hydraulic cylinder of hydraulic motor and is connected with single-chip microcomputer 2 signal；Described register 4 and monolithic
Machine signal connects, for showing accumulative rock drilling depth.
In the present embodiment, the feed motion of rock drilling equipment drives chain to realize by hydraulic motor, tumbler 11 with
The output shaft of hydraulic motor is directly fixed, and for the number of turns of direct detection hydraulic motor rotation, is converted into rock drill feeding depth.
Preferably, described tumbler 11 is the rotating disk being directly anchored in hydraulic motor rotating shaft.Described signal source is to install
Induced magnet on rotating disk 11.Described induction pieces 12 are four magnetic induction switches, and four magnetic induction switches are evenly distributed on together
By the concentric circular girth quartering on heart circle.
Specifically, the mounting structure of described tumbler 11 and induction pieces 12 is: prepares the gold of a same diameter concentric with rotating disk
Belong to plectane, in 4 φ 12 installing holes of round metal twist drill, 4 holes require to be distributed on Dial Signal source with the circumference of diameter, are used for
Fix 4 magnetic induction switches.When rotating disk rotates, inswept 4 magnetic induction switches send signal to induced magnet one by one.
For ensureing the steady operation of single-chip microcomputer, improve input, the capacity of resisting disturbance of output signal, as shown in Fig. 2 single-chip microcomputer
Between induction pieces, it is connected by optocoupler 5 between single-chip microcomputer and pressure switch.Further, register 4 is provided with work
Display lamp, count pulse display lamp and register output indicator, are connected by optocoupler 6 between register and single-chip microcomputer.
During real work, reach the long purpose of meter by counting the rotating cycle of tumbler 11；Pressure switch 3 dynamic
Whether make, just reflect the instantaneous operating conditions of hydraulic gate, such as in the hollow travel stage of rock drill ascent stage and decline,
Pressure switch 3 will not action, at this moment, just do not count；Only phase of boring, the rising of hydraulic cylinder oil pocket pressure, the actuating of relay
When, just count.
The concrete counting principle of magnetic induction switch is: four magnetic induction switches are divided into two groups, first group cry respectively " estimated
1 ", " count 1 ", second group is cried " estimated 2 ", " counting 2 " respectively.When estimated sensor acquisition is to signal, single-chip microcomputer will be expected
The status indication of sensor for " 1 " and preserves, and when sensor for countering collects signal, the automatic inquiry of single-chip microcomputer is expected accordingly
The flag state of sensor；If being expected accordingly, sensor mark state is " 1 ", and count is incremented for single-chip microcomputer, and will be all estimated
The flag state of sensor is clear " 0 "；If being expected accordingly, sensor mark state is " 0 ", and single-chip microcomputer does not count, and will own
The flag state of pre- flowmeter sensor is clear " 0 ".Advantage of this is that, not only eliminate operational vibration to the impact counting, count
Accurately, and effectively prevent from counting during reversion.
As shown in figure 4, in the present embodiment, the diameter of rotating disk is preferably 100mm, the display digit minimum controlled quentity controlled variable of register
It is preferably 0.1 meter.So, the Zhou Changwei 314mm of turntable rotation one circle, turns 1 circle and sends 2 count pulses, i.e. 1 pulse table
Show and dig into 157mm, close 0.157 meter.Register should be walked step number and round for (overall pulse number × pulse equivalency)/100, wherein, pulse
The unit of equivalent is mm/p.Produce 0.1 meter of loss of data for avoiding having a power failure shutting down, when remainder between 0.05～0.099 meter it
Between when, first more walk 1 step, such as: single-chip microcomputer receives the 1st count pulse, 0.157 meter of overall length, first control motor to walk 2 steps；Receive
To the 2nd count pulse, 0.314 meter of overall length, total step number is 3, and the total step number above walked is 2, so 1 step of only need to going further is
Can；Receive the 3rd count pulse, 0.471 meter of overall length, total step number is 5, and the total step number above walked is 3, so only need to go further 2
Walk；By that analogy.During actual count, for preventing cumulative error, processed using absolute data, i.e. from chisel
Whole accumulative effective count pulse since rock equipment runs is total, is multiplied by length pulse equivalent, draws total Excavation Length；Then
According to total length, calculate should output control register step number, and round up, so so that it may make final absolute
Error in dipping controls in 0.05 meter.Data is saved in the rom in single-chip microcomputer for a long time, not power failure influence.
As a kind of equivalent implementations of the present embodiment, magnetic induction switch can also be changed to six, divides three groups, counts former
Reason is similar with two groups, and the pulse equivalency being each pulse is changed into 104.7mm；Counting process in detail repeats no more here.
Embodiment two
A kind of metering rock drilling equipment adds up the mechanical type counting assembly of rock drilling depth, comprising: synchronous counting wheel, single-chip microcomputer,
