Description
Technical field
The invention belongs to rubber conveyer belt technical field, relate to a kind of conveying belt test method and device, be specifically related to the license of a kind of conveying belt and hold diameter method of testing and device.
Background technology
Rubber conveyer belt in use needs to surround on each head roll, bend pulley, the selection of diameter of cylinder will according to the structure of rubber conveyer belt, conveyor Selection and Design handbook generally can be found, and the thickness of conveying belt, the kind of conveying belt framework material correspond to great diameter of cylinder.
But the data that Selection and Design handbook is recorded are generally more conservative, this means that diameter of cylinder is generally selected all bigger than normal, the supporting structure parts specification of corresponding belt conveyor is all bigger than normal, and the cost of conveyor is higher, causes the waste of material.Moreover, the structure not complete standardization of conveying belt, the conveyer belt structure of each producer design is also incomplete same, the conveyer belt structure that each producer designs for different use occasions is not identical yet, whether can be used on the cylinder of a characteristic diameter for some specific rubber conveyer belts, up to the present a kind of suitable means of testing is not also had, this is also the difficult problem always perplexing conveyer belt structure slip-stick artist and conveyor design engineer, and also nobody finds out test way till now.
For the belt conveyor that the structure used has been determined, conveying belt is consumable accessory, user is when ordering conveying belt spare part, when proposition belt conveyor needs raising output, raising belt speed etc. to require, conveying belt needs to improve specification, namely the size increasing gauge and augmenting bone frame material is needed, conveyer belt structure slip-stick artist and conveyor design engineer will determine whether original cylinder can also use, if do not change original cylinder in the normal use of guarantee, so can save next extensive fund to user again.So determine that the conveying belt of ad hoc structure permits that the problem holding diameter is extremely important.
Summary of the invention
The object of the invention is to improve the deficiencies in the prior art part, provide a kind of conveying belt to permit to hold diameter method of testing and device.
The present invention is achieved through the following technical solutions:
A kind of conveying belt license holds diameter method of testing, comprises the steps:
1) according to configuration settings diameter value to be measured of conveying belt, such as 400 millimeters;
2) along the sample block of conveying belt longitudinally cutting one piece of strip, width 40 to 100 millimeters, length equals diameter to be measured and is multiplied by π divided by 2, and add two clamping lengths, clamping length is within the scope of 30 to 100 millimeters; When diameter to be measured is 400 millimeters, sample block length equals 400x pi/2 and adds two clamping lengths;
3) two ends of sample block are clamped a clamping length respectively, two parallel just right by retaining part, and two are equaled diameter to be measured by the distance of retaining part; When diameter to be measured is 400 millimeters, this distance is exactly 400 millimeters, and make sample block curve semicircle, half circular diameter equals diameter to be measured;
4) place and to observe after half an hour or whether to have obvious fold with the circular arc medial surface that hand touches sample block, said obvious fold is highly greater than the fold of 2 millimeters, and whether each hierarchy of conveying belt has significantly is separated from each other; If conclusion is "No", this conveying belt permission to use is the cylinder of this mensuration diameter in diameter, if conclusion is "Yes", does not allow to use.
If in step 4) in obtain the conclusion of "No", then diameter adjustment to be measured is diminished, such as be adjusted to 350 millimeters, repeat 2) to 4) testing procedure, if 4) in get back the conclusion of "No", then diameter to be measured is adjusted again and diminish, until obtain the conclusion of "Yes"; If 4) in obtain the conclusion of "Yes", then diameter adjustment to be measured is become large, such as 450 millimeters, repeat 2) to 4) testing procedure, if 4) in get back the conclusion of "Yes", then diameter to be measured is adjusted again and becomes large, until obtain the conclusion of "No".Finally obtain in step 4) in conclusion be "No" and the minimum diameter to be measured of numerical value, this diameter to be measured holds diameter as the minimum license of conveying belt.
Diameter of cylinder is too little, unfavorable to the operation of conveying belt, obviously can shorten the serviceable life of conveying belt, diameter is too large, and the price of cylinder is higher, and the supporting structure parts specification of corresponding conveyor is all bigger than normal, significantly improve the cost of conveyor, cause the waste of material.Cylinder can be divided three classes according to use location, determine their diameter respectively: first kind cylinder, belt direction changes and is less than the bend pulley of 30 degree, and the diameter of this bend pulley is equal to or slightly greater than and minimumly holds diameter; Equations of The Second Kind cylinder, belt direction changes the bend pulley being more than or equal to 30 degree, and the diameter of this bend pulley is equal to or slightly greater than minimum 1.6 times of holding diameter; 3rd class cylinder, i.e. head roll, diameter is equal to or slightly greater than minimum 2.56 times of holding diameter.In GB GB/T10595, define the normal diameter series of cylinder, generally get into larger numerical value adjacent in normal diameter series.
Hold diameter method of testing according to above-described conveying belt license, devise the license of a kind of conveying belt and hold diameter proving installation, comprise panel, fixed head, movable gusset, strap and web joint; Panel is strip, has panel front and back side of panel, and fixed head is fixedly connected on one end of panel, and strap and fixed head are bolted, and the first end of sample is sandwiched between strap and fixed head, and frictionally is fixed and can not be moved; Panel has long sliding hole, and movable gusset comprises two orthogonal, is clamping face and stationary plane respectively, stationary plane is close to panel front, web joint is close to back side of panel, and bolt is linked together stationary plane, panel and web joint through long sliding hole, and frictionally is fixed and can not be moved; Clamping face and ambulatory splint are bolted, and the second end of sample is clipped in the middle of clamping face and ambulatory splint.
