Description
Technical field
The invention belongs to paver technical field, particularly a kind of paving width measuring system and method with the paver of freely-moving mangle, also relates to a kind of paver with paving width measuring system.
Background technology
Paver a kind ofly receives material spreader and the equipment carrying out it on whole paving width distributing again that screeding and compaction is finally shaped road surface, generally comprises travel mechanism, hopper, feeding unit, feeding distribution mechanism and screed etc.Screed is used for screeding and compaction material spreader and the road surface that is finally shaped, and usually has mechanical assembled screed and freely-moving mangle two kinds of forms.Machinery assembled ironing plate is assembled by the lengthening section screed of principal piece screed and multiple different in width; Freely-moving mangle then comprises principal piece screed and telescopic section screed, and telescopic section screed can be laterally also namely flexible on paving width direction relative to principal piece screed.Usually, freely-moving mangle all has symmetrical left and right telescopic section screed.
For mechanical assembled ironing plate, when needs change paving width, need the erection method changing principal piece screed and lengthening section screed, such as, increase or reduce a certain or a few sections of lengthening section screeds.And for freely-moving mangle, when needs change paving width, only need to make telescopic section screed relative to principal piece screed transversal stretching.Certainly when freely-moving mangle paves for larger paving width, also can in the outside of telescopic section screed other lengthening section screeds assembled again.
An important parameter and test rating when paving width is pavement construction, a lot of pavement engineering can specify that one relative to the error range of specifying paving width, and the paving concrete pavement exceeding this error range can be identified as defective.In addition, other parameters that paving width is also conducive to controlling paver are obtained.Therefore, when pavement construction especially uses freely-moving mangle, need to obtain paving width every now and then.Method conventional at present, by manually adopting tape measure, comparatively wastes time and energy.
