In another embodiment, the present invention also proposes a kind of to utilize above-mentioned generating laser and laser pickoff to determine The method for treating the plane of reference of grade, determined according to this method after the plane of reference (or referred to as reference plane) of grade, Laser leveling machine can treat grade according to the plane of reference and be flattened, and obtain the grade of high-flatness.In this implementation In example, the method for determining to treat the plane of reference of grade using above-mentioned generating laser and laser pickoff comprises the following steps:
First laser receiver, second laser receiver and the 3rd laser pickoff are interspersed and are fixed on and treated by S100 On grade, and make the laser pick-off window of first laser receiver, second laser receiver and the 3rd laser pickoff The distance between centre position and absolute altitude are default distance;
Generating laser is fixed on and treated on grade by S200, make the pulse laser of laser transmitter projects it is inswept treat it is whole Plane earth, and the height of flexible A-frame 390 is adjusted to default height, so that the stroke of hoistable platform 310 is in work model In enclosing;
S300 generating laser automatic height adjustments, until connecing the laser of pulsed laser irradiation to first laser receiver Receive the centre position of window;
S400 generating lasers keep the centre position of the laser pick-off window of pulsed laser irradiation first laser receiver It is constant, while the height and angle of pulse laser are adjusted, until making pulse laser while irradiating first laser receiver and second The centre position of the laser pick-off window of laser pickoff;
S500 generating lasers keep the laser window of pulsed laser irradiation first laser receiver and second laser receiver The centre position of mouth is constant, while adjusts the height and angle of pulse laser, until making pulse laser while irradiating first laser Grade is treated in the centre position of the laser pick-off window of receiver, second laser receiver and the 3rd laser pickoff, completion The plane of reference determination.
Specifically, first in the step s 100, by first laser receiver, second laser receiver and the 3rd laser pick-off Device is interspersed and is fixed on and treats on grade, is interspersed in the present embodiment and refers to first laser receiver, second laser Receiver and the 3rd laser pickoff are not arranged on the same straight line, simultaneously so that first laser receiver, second laser receiver The distance between the centre position of the respective laser pick-off window of 3rd laser pickoff and absolute altitude are default distance, due to In the leveling engineering construction of the ground of reality, before leveling, it is necessary to the absolute altitude delimited in advance according to professional survey crew and The physical length of laser pickoff determines the distance between centre position and absolute altitude of the laser pick-off window of laser pickoff, should Distance as pre-determined distance, but due to treating that the angle of inclination of grade is not quite similar, therefore pre-determined distance can be applied according to engineering The specific requirement of work and determine.
In step s 200, the foregoing generating laser of the present invention is fixed on and treated on grade, and make Laser emission The pulse laser of device transmitting is inswept to treat grade, so as to ensure to be fixed on the first laser receiver treated on grade, the Dual-laser receiver and the 3rd laser pickoff are all in the scanning range of generating laser, the pulse of laser transmitter projects Laser can be received by first laser receiver, second laser receiver and the 3rd laser pickoff;Meanwhile adjust laser hair The height of the flexible A-frame 390 of emitter is to default height, so that the stroke of hoistable platform 310 is in working range, its In default height and working range depending on specifically treating the inclined degree of grade, generating laser is adjusted in this step Flexible A-frame 390 height to default height so that mesh of the actuating length of hoistable platform 310 in working range , it is to prevent hoistable platform 310 from can not also determine to treat the ginseng of grade even if reducing as far as possible or rising to peak The situation for examining face occurs.
Step S300 exists first to the process that step S500 is that generating laser automatically determines the plane of reference for treating grade In step S300, generating laser is under the control of information processor, automatic height adjustment, until arriving pulsed laser irradiation The centre position of the laser pick-off window of first laser receiver, in this process, information processor drive electricity by motor Road drives motor 320, hoistable platform 310 is risen or is declined under the drive of motor 320, when first laser connects When receipts device receives the pulse laser of laser transmitter projects, first laser receiver passes through the second communication wireless module and first Communication between wireless communication module, positional information of the pulse laser on its laser pick-off window is sent to Laser emission Device, the positional information that generating laser feeds back according to first laser receiver judge whether pulse laser is radiated at first laser and connects The centre position of the laser pick-off window of device is received, if being radiated at centre position, the information processor of generating laser stops Only to the driving of motor 320, and then the adjustment of shutheight.
Then, in step S400, generating laser keeps the laser pick-off of pulsed laser irradiation first laser receiver The centre position of window is constant, while height and the angle of pulse laser are adjusted by angle adjusting mechanism 200 and elevating mechanism 300 Degree, until making pulse laser while irradiating the interposition of the laser pick-off window of first laser receiver and second laser receiver Put, now, generating laser finds several planes formed by pulse laser, and each plane swashs by first The centre position of the laser pick-off window of optical receiver and second laser receiver.
Finally, in step S500, generating laser keeps pulsed laser irradiation first laser receiver and second laser The centre position of the laser window of receiver is constant, while adjusts arteries and veins again by angle adjusting mechanism 200 and elevating mechanism 300 The height and angle of impulse light, until making pulse laser while irradiating first laser receiver, second laser receiver and the 3rd The centre position of the laser pick-off window of laser pickoff, the plane that now pulse laser is formed are exactly to treat the ginseng of grade Face is examined, so far generating laser completes automatically determining for the plane of reference for the treatment of grade.
