Description
技术领域technical field
本实用新型属于起重机检测技术领域,涉及一种检测起重机主梁上拱曲线的装置。The utility model belongs to the technical field of crane detection and relates to a device for detecting the upper arch curve of a main girder of a crane.
背景技术Background technique
起重机主梁是最重要的结构件之一。为保证起重机主梁的上拱要求,主梁制造时腹板下料就要制出上拱。The crane girder is one of the most important structural components. In order to ensure the arching requirements of the main girder of the crane, the web blanking will produce the arching during the manufacture of the main girder.
得到起重机主梁上拱完整曲线对于起重机的检测具有重要意义,如得到主梁上拱度;有助于精确建立主梁模型,分析主梁力学性能;对比不同工况下的主梁上拱曲线,可以得到主梁上各点的下挠度等等。Obtaining the complete arching curve of the main beam of the crane is of great significance for the inspection of the crane, such as obtaining the arching degree of the main beam; it is helpful to accurately establish the main beam model and analyze the mechanical properties of the main beam; compare the arching curve of the main beam under different working conditions , the downward deflection of each point on the main beam can be obtained and so on.
目前,市面上并没有针对起重机主梁上拱曲线的检测装置,起重机主梁上拱曲线在实际生产使用中主要有四种计算模型:正弦曲线、二次抛物线、三折线及四次曲线,抛物线曲线在两端的坡度较大,四次曲线比较平缓,正弦曲线介于以上两者之间,三折线中间段水平。起重机主梁在下料时根据起重机工作需求、自身结构等因素选择不同的曲线模型,对于焊接下挠量较小的偏轨箱形梁可采用三折线腹板下料,对于正轨箱型主梁腹板宜采用四次抛物线加二次抛物线。起重机主梁在经过一段时间使用后会发生一定变形,此时曲线模型已经不能精确反映主梁的上拱,而现有的主梁上拱曲线的测得方法均是根据起重机主梁上拱度及若干点的拱度推算得出,追根究底是一种估算方法,并不能真实反映主梁上每一点的拱度。At present, there is no detection device for the arching curve of the main girder of the crane on the market. There are mainly four calculation models for the arching curve of the main girder of the crane in actual production and use: sine curve, quadratic parabola, tri-fold line and quartic curve, parabola The slope at both ends of the curve is relatively large, the quartic curve is relatively gentle, the sinusoidal curve is between the above two, and the middle section of the three-fold line is horizontal. When blanking the main girder of the crane, different curve models are selected according to the working requirements of the crane, its own structure and other factors. For off-track box girders with small welding deflection, three-fold line web blanking can be used. For regular box girder webs The plate should adopt a quartic parabola plus a quadratic parabola. The main girder of the crane will be deformed after a period of use. At this time, the curve model can no longer accurately reflect the arching of the main girder, and the existing methods for measuring the arching curve of the main girder are all based on the arching degree of the main girder of the crane. And the camber of several points is calculated, the bottom line is an estimation method, and it cannot truly reflect the camber of each point on the main beam.
