Description
Technical field
The present invention relates to the lifting of main equipment, specifically refer to the dynamic measurement device and the measuring method of large-scale perpendicularity deviation of hoist lifting hook.
Background technology
The lifting of main equipment, light hundreds of ton then, heavy then go up kiloton, it is very important that such equipment lifting back control suspension hook is in the nature plumbness, otherwise equipment is easy to generate swing, might injure equipment and personnel near it.
The method of control suspension hook verticality is to be held by lifting commanding's naked eyes and years experience at present.When telpher lifts, generally can be controlled within 2 ° of deviations; And for large crane because its arm is very long, the people stand in suspension hook near, can produce the collimation error, judge that whether naturally vertically suspension hook, has very big difficulty.This just may cause suspension hook to carry out big part lifting under the situation of big off-center perpendicular line, brings potential safety hazard, even causes serious accident.
The method of measuring vertical has multiple, and for example directly vertical by surveying, the transit survey is vertical etc.For example " Chinese special equipment safety " the 23rd volume the 1st interim " total powerstation integrated application in crane detects " of publishing, its measurement point is in ground fixed position, set up coordinate system, by multiple measurement, determine any coordinate of space, poor according to 2 coordinate, calculate the distance of point-to-point transmission, numerical value is presented on the total powerstation; If this technology is applied in the measurement of suspension hook verticality, can only be to carry out indirect measurement on one's own time, the dynamic deviation for suspension hook when in running order is then powerless.The patent No. is that the Chinese utility model patent of ZL200720086087.4 disclosed " laser measuring device for measuring " is to adopt the laser verticality measurer to measure the verticality of fixed object, it is fixed on the upper position of vertical object, according to the offset deviation that receives, draw the deviation of verticality; Equally, this laser verticality measurer can't be measured for the perpendicularity deviation of dynamic object.And for example the patent No. be ZL93238246.0 disclosed " portable intelligent verticality measuring instrument " its be to adopt the perpendicularity deviation of measuring the smallclothes fixture by the survey method.For another example, application number is 200710028355.1 Chinese invention patent application disclosed " a kind of squareness measurement method and verticality measuring instrument ", it utilizes the proportional principle of similar triangles corresponding sides, in the measuring vertical degree, need not directly measure the axial length of high-rise structures, the difference that only needs the measuring appliance bus to depart from gets final product; Equally, all measurements of inapplicable dynamic deviation of this measuring method and measuring instrument.
Because in hoisting process, suspension hook is in the state of motion all the time, the detection of its verticality has certain singularity, and detecting instrument and the method at dynamic suspension hook nature verticality also do not have at present.
