Description
Technical field
The invention belongs to detection technique field, relate to a kind of method of testing and device of the tubulose band lateral stiffness for circular pipe belt type conveyer, be specifically related to a kind of tubulose band lateral stiffness method of testing and device.
Background technology
Circular pipe belt type conveyer, on the basis of flute profile belt conveyor, to develop and come, flat shape conveying belt is after leaving aircraft tail cylinder, under the guide effect of carrying roller, automatically be rolled into tubular, two band edge laps overlap, material is enclosed in pipe, every a segment distance, just arranges one group of carrying roller, is evenly distributed on around pipe, form regular polygon, tubulose band is applied to suitable pressure, bear its weight, make it can keep tubular, and can play the guiding role to tubulose band, make tubulose band along linear or the operation of circular arc path.Before head discharging, under the guide effect of carrying roller, be automatically opened into flat shape, unsnatch material, walk around head drum, while returning to charging place, can enclose into tubulose, can be also flat shape.
The conveyor of this pattern, has lot of advantages.
First, it can be turned at any three-dimensional, arranges very flexibly in space, can grow the cross-country conveying of distance, during installation, can lay along earth's surface, and dipping and heaving gets over or left and right turning cut-through thing, without ditching or tunnel, can cross over stream.
Secondly, it can seal conveying, can be because of material airborne dust contaminated environment, and dust or other dirt that the material of its transportation also can not kicked up in environment pollute, and are not afraid of wind and weather, and without hood, not required corridor, belongs to environmental type machinery.Material can not got by near resident's key yet.
So in recent decades, circular pipe belt type conveyer is extensively promoted the use of in worldwide.
Tubulose band, transport agent as circular pipe belt type conveyer, playing the part of at work very important role, its usability, especially lateral stiffness, directly affect it self the rate of wear and serviceable life, also affect the movement capacity of circular pipe belt type conveyer, power consumption, serviceable life, failure rate, so how the lateral stiffness of Validity Test tubulose tape test sample piece is a very important problem, up to the present particular study personnel and testing tool are also few, to use simple equipment mostly, carry out artificial spot measurement, reading out data record, efficiency is lower, image data is less, error rate is higher.
Application number is 201220601349.7 utility model patent, name is called < < tubulose band lateral stiffness proving installation > >, described a kind of test macro that can automatically test tubular conveyor belt lateral stiffness, it is comprised of rack mechanical structure, mechanical driving part, pressure sensing structure, data transmission system, computer control system etc.Mechanical part adopts regular hexagon structure to carry out six point measurements; Running part adopts toothed belt transmission, can automatically measure the tubulose band of different-diameter, controls and tcp data segment employing PLC control and special data transmission system, and computer control system is processed data.Major function comprises: tubular conveyor belt to be measured is placed in test macro physical construction, by pressure sensing mechanism, record different-diameter conveying belt lateral stiffness value, and the lateral stiffness value recording is transported to computer system, carry out data processing, the lateral stiffness value of measurement is exported and edited, can also obtain rigidity value curve over time, and then instruct using and producing of tubulose band simultaneously.
These patent energy real-time collecting data, and send computing machine to and carry out analyzing and processing, do not need manual measurement, read and record data, there is the feature of robotization, image data is more, and test and record are more objective, but this design proposal also has very large defect.
First, along tubulose band, axially only arranged one group of measuring head, this group comprises six measuring heads, and measuring head is positioned at the point midway of pipe axial length.In this case, test specimens piece can not size be done too greatly vertically, otherwise because the two ends that exist of tension force become large from measuring head compared with distal part position caliber, the size decreases of overlapping overlap joint, two ends form hydraucone shape, the shape of tubulose band is in use compared unexpected variation has been occurred with reality, can not simulate better tubulose band truth in use, and the data of its test also can obviously depart from real data naturally.
Secondly, when on rectangular being with, sample is tested in intercepting, regardless of being machine cuts or adding thermal cutting, its physical property of position from cutting section close to can change, and can change bounding force, internal stress between sample interior each several part, and can show by tension change, test specimens piece axial length is less, the ratio that affected area domain sizes accounts for sample piece overall dimensions is larger, and this impact is more obvious, so its test result can depart from actual numerical value significantly.
Also have, 6 test points are only set, and usable range is restricted, and the quantity of actual one group of carrying roller of tubular belt conveyer is not limited to only use 6,4,8,12 or other quantity are set sometimes, need to design the more testing equipment of test point for user.
In fact, all scientific research personnel are following industry standard.Standard No. is the chemical industry standard of HG/T4224-2011, title is < < steel cord core tubular conveyor belt > >, in the preparation of the A.1 money sample in its appendix A < < lateral stiffness assay method > >, stipulate: " sample should be from cutting three from taking the lead the position of 500mm; width is the full duration of band, and length is 75mm ± 1mm." scientific research personnel few people in industry query to the sector standard.For so little size, on test apparatus, can only arrange one group of measuring head.
Summary of the invention
