The utility model provides a kind of windlass wirerope detection architecture of avoiding misjudgement, erroneous judgement.
Refer to Fig. 1 and in conjunction with shown in Fig. 2, in the embodiment of the utility model, the described windlass wirerope detection architecture of misjudgement, erroneous judgement of avoiding is except comprising power supply (not shown), connecting computing machine (not shown), also comprise wirerope 10, image collecting device 20, wherein: this wirerope 10 is loopy moving members, this image collecting device 20 is fixed components of installing near wirerope 10.
Described wirerope 10 is longitudinally to arrange, and is at least 1, in Fig. 2 of the present embodiment, is equidistantly side by side provided with 4, and comprises disconnected strand or fracture of wire 12 outside in target area disconnected strand or fracture of wire 11 and target area.
This image collecting device 20 is to installing by wirerope 10, and comprise taking main part as carrier the camera 21 and first arranging, the 21 word laser line generator 22, 23(is hereinafter to be referred as " first, second laser "), wherein: this main part is E shape and can be divided into top A, middle part B and bottom C, this top A forms protuberance to the right with respect to described middle part B, this protuberance has the first inclined-plane (this first inclined-plane is 45 degree) that connects following face and right edge face, this bottom C forms indentation portion left with respect to described top A, this indentation portion has the second inclined-plane (this second inclined-plane is 45 degree) that connects top face and right edge face, described first, the second inclined-plane forms corresponding Eight characters shape jointly, this camera 21 described middle part A with suitable collection the orientation setting of wirerope 10 partial front images of process, its pickup area is called target area 30 in the present embodiment, described first, second laser 22, 23 is identical components, be arranged at respectively protuberance and indentation portion, wherein: be arranged on the parallel first inclined-plane setting of light outlets of the first laser instrument 22 of this protuberance, the light curtain of this first laser instrument 22 can be projeced in described target area 30, and with process wirerope form hot spot 31, in like manner, be arranged on the parallel second inclined-plane setting of light outlets of the second laser 22 of this indentation portion, the light curtain of this second laser 22 also can be projeced in this target area 30, and form hot spot 31 with the wirerope of process, described hot spot comprises normal hot spot 311 and abnormal hot spot 312, the quantity that the abnormal hot spot 312 forming when wirerope breaks thigh or fracture of wire in figure is less than normal hot spot 311 and hot spot is (as 8 of normal hot spots, after disconnected strand, be divided into two, have more 1), position (as the change in location with disconnected strand wirerope) occurs abnormal, detection architecture can be simple by this, accurately by hot spot relatively determine operating wirerope whether extremely.
In the utility model embodiment, this camera 21 comprises main part 211, camera lens 212 and optical filter 213, and described optical filter 213 is located between main body 211 and camera lens 212, also can be located at before camera lens 212 because of environment or equipment structural factor.The design of this optical filter 213 be for the light outside filtering laser instrument, avoid other light to be gathered by camera 21 and to the judged result making mistake.
In the utility model embodiment, the parallel first inclined-plane setting of light outlets of this first laser instrument 22, and parallel the second inclined-plane setting of the light outlets of this second laser 23, in fact these two is relatively tilt 45 degree to the wirerope projection light curtain in target area 30 and form hot spot 31, this kind forms the technological means of hot spot 31 on wirerope by inclination miter angle projection light curtain, avoid projecting wirerope and on object, formed the technical matters that has nothing to do hot spot and cause misjudgement, erroneous judgement behind, thereby effectively promoted the precision that wirerope detects.
In the utility model embodiment, be necessary that it is detected to effect illustrates, for example: first, second laser instrument 22,23 is when connecting direct supply projection light curtain to wirerope 10 in target area, and the position of hot spot 31, size, shape and quantity etc. are constant (as normal hot spots 311 in Fig. 2) under normal circumstances; In the time that appearring in wirerope 10, (as disconnected strand or fracture of wire 11) abnormal conditions can there is corresponding variation (abnormal hot spot 312 in as Fig. 2) because of abnormal (as facula position, size, shape or the quantity) of wirerope 11 in hot spot 31.Because wirerope 10 is that its detection architecture is mounted in these wirerope 10 right opposites and detects incessantly, so this detection architecture exists and detects dead angle hardly in application, has effectively improved safety coefficient according to the track action of setting.
