Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
See Fig. 1, this ground mobile working platform for electronic device comprises table top 5, four leveling support legs 1,2,3,4 and level sensor 6.The side of table top 5 is connected with shell loop bar 7 bolts of leveling support leg.
Leveling support leg comprises base 8, flexible transfer bar mechanism and driving mechanism.
There is a hemispherical groove at base 8 middle parts; Flexible transfer bar mechanism comprises push rod 9 and suit shell loop bar 7 thereon, and push rod 9 is a hollow stem, and push rod 9 roof anchorage are installed with and leading screw 10 nut engaged 11, and the ball pivot that the bottom of push rod 9 is equipped with the hemispherical groove fit of base 8 supports 12; The upper end of shell loop bar 7 is connecting casing, between shell loop bar 7 bottoms and the push rod 9 axle sleeve 17 is housed, and axle sleeve 17 is connected with shell loop bar 7 by key 18; Telescopic process Intermediate shaft sleeve 17 slides along push rod 9;
Leading screw 10 is contained in the push rod 9, and leading screw 10 is a ball screw, with leading screw 10 nut engaged 11 be ball nut.The upper end of leading screw 10 is installed with bearing 13, axle sleeve 14, annular harmonic wave speed reducing machine 15 and motor 16 successively.Motor 16 is the MSMA082A1A actuating motor, and the output shaft of motor 16 is connected with leading screw 10 ends;
On the axle sleeve 14 gearwheel is installed, the small gear that meshes with gearwheel is installed on the casing by manual crank shaft 19; Axle sleeve 14 is the step axle sleeve, and axle sleeve 14 tops are set with single-row radial ball bearing, and the bearing 13 on the leading screw 10 of single-row radial ball bearing below is a thrust-bearing; Between the leading screw 10 of thrust-bearing below and the shell loop bar 7 single row angular contact ball bearing is installed, sees Fig. 2, Fig. 3.
Level sensor 6 is installed on the table top 5, and level sensor 6 is connecting four motor 16 on the leveling support leg respectively by lead; Level sensor 6 is connecting control mechanism simultaneously.
During work, motor 16 is just changeing drive leading screw 10 and is rotating, and drives shell loop bar 7 during leading screw 10 and rises, and drives leveling and supports the leg elongation, during motor 16 counter-rotatings, drives the contraction of leveling support leg.
Under the ruined situation of power supply, still can drive leading screw 10 by manual crank shaft 19 and gear driving pair and rotate, flexible leveling support leg.
The present invention is 4 support automatic horizontal control systems, and what at first will solve is exactly 4 problems that land simultaneously.From solid geometry as can be known: 3 fixed planes.For four strong points,, can obtain four planes by permutation and combination.Therefore must guarantee at four strong points it all is to carry out the work leveling under the situation about landing to be only unique.The way that addresses this problem is on four strong points the Pressure testing ability to be arranged all.After the PLC module CPU226 of control mechanism received leveling instruction, MSDA083A1A sent instruction to motor driver, drove that actuating motor MSMA082A1A is rotated in the forward simultaneously on four leveling support legs, drove that to support leg downward.Support leg when leveling and land, the load increase causes motor drive current to increase, and driver is transformed to dtc signal with motor current signal and gives analog amount input/output module EM235, gives CPU226 after EM235 does the A/D conversion.The CPU226 of control mechanism changes automatic leveling process over to after judging four supports legs are in the state of landing according to the variation of every leg torque again.
Automatically leveling.Level sensor 2 by cable the error signal of working platform and desirable level face be decomposed into X, Y-axis two-way orthogonal signalling are delivered on the EM235 of control mechanism, EM235 carries out error signal to deliver among the PLC module CPU226 after the A/D conversion.PLC module CPU226 is judging that after the support leg is realized the state that lands level error signal being for conversion into the signal of controlling motor steering and rotating speed outputs among the corresponding motor driver MSDA083A1A, and the signal that motor driver is imported PLC amplifies the actuating motor MSMA082A1A on the rear driving support leg.When X-axis was positive error, the actuating motor synchronous forward that leg 3 and 4 are supportted in PLC control drove.Along with the liter of two leveling support legs 3 and 4 is long, the X-axis error is reducing, and the speed of motor is slowing down; When error during less than specified value, motor speed is zero.In like manner, when Y-axis is positive error, drive support leg 1 and 4; When X-axis is the negative sense error, drive support leg 1 and 2; When Y-axis is the negative sense error, drive support leg 3 and 2.When the horizontal error of XY axle during, lock four support legs all less than predetermined range; So far leveling work is finished.
Stateful Inspection.As long as the automatic horizontal control system energising, the PLC of control mechanism is the state of each link of monitoring system all the time, to guarantee the Security of system works.Each motor driver all reports PLC to the state of oneself (containing fault) information, and PLC does not have in the affirmation system just to carry out the everything instruction under the situation of fault, if break down in the running, PLC is timely autostop also.Secondly, when motor moved, motor driver sampled the torque of motor and tachometer value return, and gave PLC module CPU226 by another analog amount input/output module EM235.The PLC module CPU226 of control mechanism judges according to the size of the torque value of motor whether the support leg lands and whether motor transships.Judge according to speed feedback whether the motor operation is synchronous.The PLC of control mechanism carries out the stroke detection that integration is realized the support leg to rotating speed of motor in every running, avoids supportting leg in the leveling process, the phenomenon of stroke occurs.
