Description
Technical field
The present invention relates to a kind of proving installation of conveying machinery parts, relate to a kind of proving installation of resistance coefficient of belt conveyor up cradle roll specifically, it is a kind of special purpose device tested resistance coefficient during single carrying roller rotation.
Background technology
Carrying roller uses in a large number on rubber conveyer.Idler resistance coefficient is a very important parameter, and its size all can produce direct impact to the operational effect of belt conveyor, serviceable life, power consumption.Idler resistance coefficient little then carrying roller operational flexibility is good, operates steadily easily, long service life, power consumption be little.Otherwise then run dumb, power consumption is large.Therefore, manufacturer, when development and design, production carrying roller, develops effect to understand or in order to control produced carrying roller product quality, all needs regularly to test its single mount roller resistance coefficient value.Past the most original detection method is: carrying roller is erected rear hand and rotate, determine the size of carrying roller rotary resistance with feel, thus its rotary resistance coefficient magnitude is calculated in assessment.The obviously relatively backward and poor accuracy of this method.More existing method of testings can test idler machining resistance coefficients, though idler machining resistance coefficients and single mount roller resistance coefficient have and necessarily to contact but the two numerical value is not identical.Idler machining resistance coefficients embodies the running status of carrying roller in groups, and it has very large relation with the environment run and force-bearing situation, and single mount roller resistance coefficient embodies degree of flexibility when certain certain certain class carrying roller runs.But some are incomplete and not enough for the existing test to single mount roller resistance coefficient, detection existence, need to be improved this.
Find that there is some relevant bibliographical informations by the domestic Searches of Patent Literature, mainly contain relevant with the present invention is following:
1, the patent No. is CN201520492248.4, and the practicality new patent that name is called " a kind of proving installation of single mount roller resistance coefficient ", this utility model discloses a kind of proving installation for testing single mount roller resistance coefficient.To the pick-up unit that single mount roller resistance coefficient on rubber conveyer is tested, comprising a L-shaped swing span can around a spot wobble, and single mount roller is placed on roller rack, and roller rack bolt is packed in swing span top; Carrying roller drive unit drives the uniform rotation of single mount roller; Arrange that in the upper right side of swing span fulcrum one touches iron, there is a limit switch on the side touched on the right of iron, when swing span is vertical stand-up state, touches iron and contacts gently with the roller of limit switch; In the below of swing span fulcrum, be furnished with 2 limited blocks; The bottom right end of swing span L shape is connected by bearing pin and electromagnet; Method of testing is: the initial speed n being measured tested carrying roller by the survey rotational speed devices be made up of reflex reflector lens and photoelectric sensor, by by touch survey time device that iron and limit switch and timer forms measure tested carrying roller do not add annulus and under adding annulus two states from initial velocity n to stopping operating the time used, just can calculate single mount roller resistance coefficient according to the formula derived.
