Embodiment
Below in conjunction with the utility model accompanying drawing, clear complete description is done to the utility model case.
As shown in Fig. 1 ~ Fig. 5, crane Static stiffness laser measuring apparatus of the present utility model, comprises laser measurement main frame 1, hand held controller 2, tripod 3, The Cloud Terrace 4, data line 5 forms.Wherein laser measurement main frame 1 comprises laser transmitting-receiving emitter 107, obliquity sensor 103, data processing circuit 102, data display window 101, base 104, data line interface 105, power switch 106 form.Wherein laser transmitting-receiving emitter 107 completes Emission Lasers to the process receiving reflected light, and obliquity sensor 103 completes angle measurement function.Hand held controller 2 realizes controlling laser measurement main frame 1 by data line and the function of digital independent, mainly comprises single-chip microcomputer treatment circuit 202, LCD display 201, operation push-button 204 and data line interface 203.Wherein operation push-button 204 comprises switching on and shutting down, online, Static stiffness is measured, remeasured.Tripod 3 adopts the special instrument supported for laser measurement main frame 1.The Cloud Terrace 4 can be connected to the special-purpose machinery unit for angle and direction adjustment on tripod.
To the operation of the utility model case and concrete implementation step as follows: base 104 and the tripod 3 of laser measurement main frame 1 are screwed, then laser measurement main frame 1 and hand held controller 2 are connected by data line 5, the instrument connected is placed on the safe distance place that the positive side of crane girder 7 is certain, ensures that the postrotational level angle of laser transmitting-receiving emitter 107 of laser measurement main frame 1 is less than 45 degree.First the power switch 106 of laser measurement main frame 1 is opened, then the power switch key of the operation push-button 204 of hand held controller 2 is opened, the online button of following click, now can send beam of laser line from the laser transmitting-receiving emitter 107 of laser measurement main frame 1, fine-adjustment tripod head 3 changes the angle that laser measurement main frame 1 sends laser, on the planar central point that laser facula adjustment is irradiated to immediately below crane girder 7, wait to be measured.
