A laser arch measuring device connected with the battery compartment is arranged on a rotating platform of the supporting seat. The laser arch measuring device comprises a data processor, and a laser range finder and a slope angle sensor connected with the data processor. The laser arch measuring instrument is used for accurately measuring the camber, flexibility and lower flexibility of the girder of overhead and gantry cranes and the like. The laser arch measuring instrument has high measuring accuracy, no measuring blind area, safe and convenient operation, no aloftwork, simple structure, small volume, light weight and portability.
Description
Technical field
The utility model relates to a kind of surveying instrument, is specially a kind of camber that is used for overhead and gantry cranes tool etc., goes up set-back, the laser arch measurer accurately measured of amount of deflection down.
Background technology
The overhead and gantry cranes camber is tested, being the examination project of stipulating in JB/T53442-29 " the general-purpose overhead crane product quality is graded " standard, also is the middle emphasis Interventions Requested of stipulating of " hoisting machinery supervisory quality inspection procedure " (promulgation in 2002 on October 8, of [2002] No. 296 literary compositions of state's quality inspection pot is carried out) that State Administration for Quality Supervision and Inspection and Quarantine formulates.The domestic existing method of inspection mainly contains steel wire method, spirit-leveling instrument method, the Laser straight line appearance method of drawing at present.Above-mentioned measuring method requires survey crew must carry instrument and equipment arrival measured position when measuring or scale, receiving target (sensor) etc. is placed the measured position, at first has certain danger (work high above the ground) for survey crew, and labour intensity is big, complex operation step, and certain limitation is arranged.Draw steel wire method measuring result error bigger, though and spirit-leveling instrument is measured more accurately, the measuring method complexity is subjected to the bearing vibration influence big, needs a plurality of survey crews, carry heavy instrument and equipment, and consuming time more.
The utility model content
The purpose of this utility model will overcome above-mentioned deficiency exactly, a kind of measuring accuracy height is provided, do not have to measure blind area, easy-to-operate, need not work high above the ground and simple in structure, volume is little, in light weight, the laser arch measurer that is easy to carry about with one.
For achieving the above object, the technical solution of the utility model is, this laser arch measurer comprises the bearing with rotation platform, battery compartment and horizontal regulating and controlling mechanism have been installed on described bearing, the Laser Measuring arch device that connects with this battery compartment has been installed on the rotation platform of described bearing, described Laser Measuring arch device comprises data processor, and the laser range finder and the obliquity sensor that connect with this data processor, and described data processor has data-storing module, computing module and display module.
The utility model has been installed battery compartment and horizontal regulating and controlling mechanism on described bearing, the Laser Measuring arch device that connects with this battery compartment has been installed on the rotation platform of described bearing, described Laser Measuring arch device comprises data processor, and the laser range finder and the obliquity sensor that connect with this data processor, described data processor has data-storing module, computing module and display module.
During measurement, at first the ground correct position places instrument below measured object, use the horizontal regulating and controlling mechanism on the bearing to transfer than the instrument level, use rotation platform rotation adjusting knob to regulate the motion track and the basic keeping parallelism of crane girder (can open about laser beam in case of necessity and proofread) of laser range finder, measure girder mid point (plumb bob point) then, left end, right-hand member 3 points, accurate distance that the automatic storage of instrument is 3 and two-end-point are with respect to the accurate deflection angle of pedal line, automatically calculate the height of 3 relative horizontal basic points, and compare, demonstrate tested camber of crane main girder at last.The lower flexibility of main girder measuring method is same as described above; A point is just surveyed in the measurement of last set-back less.
Compared with the prior art, the utility model measuring accuracy height does not have the blind area of measurement, need not work high above the ground during measurement, avoid the danger of work high above the ground, need not climb up girder, a people can operate separately and finish, can guarantee the survey crew personal safety, easy and safe to operate, and simple in structure, volume is little, in light weight, be easy to carry about with one.

Fig. 1 is the utility model structural representation.
Among the figure, 1, battery compartment, 2, bearing, 3, horizontal regulating and controlling mechanism, 4, rotation platform, 5, data processor, 6, Laser Measuring arch device, 7, obliquity sensor, 8, laser range finder.
Embodiment
As shown in the figure, the utility model laser arch measurer comprises the bearing 2 with rotation platform 4, described bearing 2 has the battery compartment 1 and the horizontal regulating and controlling mechanism 3 of battery, the Laser Measuring arch device 6 that connects with this battery compartment 1 has been installed on the rotation platform 4 of described bearing 2, described Laser Measuring arch device 6 comprises data processor 5, and the laser range finder 8 and the obliquity sensor 7 that connect with this data processor 5, described data processor 5 has data-storing module, computing module and display module.
During measurement, adjust the level of bearing 2 earlier, after energized, laser range finder 8 is launched a branch of visible light beam, and obliquity sensor 7 will be worked as the top rake value through data processor 5 demonstration in real time on LCDs simultaneously.Adjust the angular deflection adjusting knob of Laser Measuring arch device 6, measure the distance and the angle of 3 at crane girder mid point (plumb bob point), left end, right-hand member respectively, and by storage key and calculation key storage and calculating, measured crane girder camber value will directly be presented on the LCDs of laser arch measurer.Can also measure the corresponding curvature value of set-back on the crane girder, following amount of deflection and other similar measured object with same method.
As measurement to overhead and gantry cranes girder camber:
At first the laser arch measurer is lain in a horizontal plane under the crane crossbeam mid point, regulate the horizontal regulating and controlling mechanism 3 on the bearing 2, eye-level bubble centering, make the instrument level, use the rotation adjusting knob of rotation platform 4 to adjust the motion track (swing guide groove) and the basic keeping parallelism of crane girder (can open about laser beam in case of necessity and proofread, the drop point of left and right sides end points laser beam gets final product in girder xsect same position substantially) that Laser Measuring is encircleed device 6 then." power supply " key opening power in the pressing function key, laser beam is aimed at girder mid point (plumb bob point, this moment, the instrument angles of display was 90 °) position, " measurement " key in the pressing function key, on the screen accurate distance and the level angle value (angle is 90 °) of display instrument to the girder mid point, " storage " key in the pressing function key is stored first group of measurement data in built-in data-storing module then; In kind surveying instrument is to distance and the level angle value and the storage of 2 of left ends, right-hand member, " calculating " key in the last pressing function key, the built-in computing module of instrument calculates girder mid point (plumb bob point), left end, right-hand member the height value and the discrepancy in elevation with respect to instrument basic point surface level automatically at 3, display module shows measurement result, promptly is the camber exact value of measured crane girder.As if result of calculation is a negative value, then the following amount of deflection of its this crane girder of absolute value representation.
Measuring method to set-back on the overhead and gantry cranes girder is measured with camber.
