Description
Technical field
The present invention relates to a kind of feeder and spend the contrast means and the matching method of probe surely, can guarantee and improve the electronic weighing type coal feeder measuring accuracy, belong to the feeder technical field.
Background technology
The feeder measuring accuracy is the of paramount importance technical indicator of feeder.
D=driving wheel diameter
Δ=thickness of belt
N=belt speed reduction unit reduction gear ratio
Speed ratio and belt speed reduction unit reduction gear ratio, driving wheel diameter are relevant with thickness of belt, and under the situation that these three values are determined, speed ratio is a constant.Feeder is in operational process, and belt speed has no idea to measure, and motor speed is an energy measurement, as long as therefore know speed ratio, with regard to energy measurement coal supply rate.
Thickness of belt is a uncertain value, and the tight some thickness of belt that belt draws will approach a bit, and is then thicker on the contrary, and through theoretical analysis and actual measurement, thickness of belt whenever differs 1mm, and measuring accuracy will differ 0.36%.So must measure actual speed ratio earlier after feeder installs, could guarantee that like this feeder has higher precision, this work is spent in the journey surely at feeder and is finished, and degree of deciding then needs degree of deciding probe, a kind of contactless detection means.When feeder was spent surely, motor speed was fixed, and belt speed just can measure actual speed ratio as long as therefore measure at this moment.
As shown in Figure 1, for the feeder body is spent probe detection method synoptic diagram surely, measuring the belt speed method is: paste reflective sheeting 2 on belt 4, on the feeder body, adorn two fixed degree probes 1,3, distance between two fixed degree are popped one's head in is fixed, after the feeder motor speed is stable, when reflective sheeting 2 during through fixed degree probe 1, computing machine picks up counting, when reflective sheeting 2 during through probe 3 timing finish, go to degree of deciding to reflective sheeting from the position of fixed degree probe 1 with regard to energy measurement like this and pop one's head in the needed time of 3 positions, just can obtain belt speed, thereby obtain speed ratio.Belt speed is measured by fixed degree probe, and therefore two fixed degree probes are crucial measurement components, measure accurately, and fixed degree probe 1,3 must be perpendicular with the belt movement direction, as shown in Figure 2.If out of plumb will produce error, shown in Fig. 3,4, in fact fixed degree probe can not be accomplished fully perpendicular to testee by the influence of processing technology, components and parts precision etc., if and two fixed degree probes vertical strap all, that will pop one's head in 1 and the probe 3 place-exchange after, the speed ratio that measures should be just the same, in fact have after the exchange ± 0.3%～± 0.6% error, so the feeder measuring accuracy requires to reach ± 0.5% just is difficult to satisfy.
Summary of the invention
The purpose of this invention is to provide a kind of a kind of feeder that can satisfy the feeder measuring accuracy and spend the contrast means and the matching method of probe surely.
For realizing above purpose, technical scheme of the present invention provides the contrast means that a kind of feeder is spent probe surely, it is characterized in that, described measurement mechanism is made up of reflective sheeting, cabinet, cabinet door, motor, circular rotating disc, two hold-down supports and Displaying Meter, timer and computing machine, motor is located in the cabinet, circular rotating disc is located on the motor, reflective sheeting is located on the circular rotating disc, two hold-down supports are located at the diagonal angle of cabinet inwall respectively, Displaying Meter is located on the cabinet door of transversal switch, timer is connected with computing machine, and computing machine is connected with Displaying Meter.
Described feeder is spent the matching method of probe contrast means surely, the steps include:
The first step: be installed in two fixed degree probes on the hold-down support respectively;
Second step: open motor, the time interval that rotating speed of motor is set to 2 of hold-down supports is more than 10 seconds, and the circular rotating disc of driven by motor does at the uniform velocity that circumference rotatablely moves;
The 3rd step: when reflective sheeting was spent probe positions surely through first, timer picked up counting, and circular rotating disc turns over 180 degree, and timer recorded the time at interval when reflective sheeting was spent probe positions surely through second;
The 4th step: timer will be presented on the Displaying Meter by computing machine in the time interval;
The 5th step: circular rotating disc continues to turn over 180 timing of timer when getting back to first after spending and spending probe positions surely, produces a time interval again to be presented on the Displaying Meter;
The 6th step: contrast test result twice, less than 0.01 or do not have, then there is not inclination in two fixed degree probes as the error amount of twice measurement;
Greater than 0.01, then two fixed degree probes exist to tilt as the error amount of twice measurement, change one of them fixed degree probe and remeasure, till pairing.
The present invention adopts the method for simulation, whether qualified, just can finish simply, efficiently deciding the pairing of degree probe with this method and measurement mechanism by reflective sheeting if mating through two fixed these two fixed degree probe droop errors of more just decidables of spending the time measured values of popping one's head in.
Advantage of the present invention is to match by given simply, efficiently degree probe, satisfies the feeder measuring accuracy.
