Abstract
The invention provides a work table lifting device driven by a motor in an earth ground surveying and mapping instrument calibration platform. The device is characterized in that the motor is installed in a base; and an actuating mechanism after speed reduction by a speed reducing mechanism drives the guide rail to lift, so as to complete the lifting motions of the lifting platform.
Description
Affiliated technical field
The present invention relates in the earth instrument of surveying and mapping calibration platform self-powered platform by Motor Control.
Background technology
Total powerstation, electronic theodolite, spirit-leveling instrument and relevant adjustment, periodic calibration in use and the legal China Metrology Accreditation work of the earth instrument of surveying and mapping in manufacture process, these adjustment detect used instrument of surveying and mapping calibration platform, are made up of many parallel light tubes, pedestal, self-powered platform three parts usually.Instrument to be detected is fixed on the self-powered platform of instrument of surveying and mapping correction station.When carrying out calibration,, to carry out lifting by self-powered platform this moment and aim at operation for the center (owing to being directional light, so rough alignment parallel light tube object lens promptly satisfy condition) of parallel light tube on the telescope rough alignment calibration platform that reaches detected instrument.
At present, the mechanical whorl structure is adopted in the worktable lifting operation bar none both at home and abroad, the calibration operator is the screw thread handwheel in the rotary work-table by hand, thereby makes the scopodromic purpose of worktable lifting to reach.Because tested instrument comes from different manufacturers and model is different, therefore the centre-height of every kind of instrument of surveying and mapping is different, whenever changes instrument of inspection usually and is transformed into another kind of height of instrument with regard to needing hand-turning just can finish from a kind of height of instrument for tens times.It is to observe infinite distant object under the micro-state of eyepiece that the detection of geodetic instrument is proofreaied and correct, and its observation process needs very meticulous, and the spirit during operation needs high concentration.At this moment, use the muscle power action under the hand-turning tens to disperse notice, be unfavorable for highly concentrating duty, and work efficiency is also slow, especially when need are frequently changed height of instrument.
Summary of the invention
In order to overcome the deficiency of manual lifting, easily carry out lifting, make spiritual high concentration state unaffected, increase work efficiency, the invention provides a kind of the earth instrument of surveying and mapping calibration table apparatus by the Motor Control lift work.
The technical solution adopted for the present invention to solve the technical problems is: settle motor as the power that drives worktable lifting in the middle of the earth instrument of surveying and mapping test board pedestal, the running of motor drives reducing gear.Reducing gear and guiding mechanism have two kinds of forms, the equal effect of tool.
One, mechanical type: the manual motor switch that motor configurations is had the may command rotating, motor drives mechanical worm worm gear reducer, coaxial pinion drives the tooth bar moving linearly in the worm gear, and tooth bar is connecting accurate round cylinder shape guide rail or dove-tail guide rail movement under the worktable.
Two, hydraulic pressure form: the motor drives gear-type pump produces hydraulic coupling, and behind the switching valve of the controlled positive and negative lifting of flow direction, the lifting chamber that liquid will inject accurate round guide rail under the worktable respectively moves up and down.
More than the guiding mechanism running that can both drive under the worktable of power after two kinds of decelerations finish lift work.
The invention has the beneficial effects as follows that this device can not only carry out lifting to worktable uniformly and stably, and can make the state of calibration person's spirit high concentration unaffected, easily carry out lift work.
Description of drawings
The present invention is further described below in conjunction with the embodiment of the present invention in the earth instrument of surveying and mapping calibration platform.
Fig. 1 is that worm and wormwheel form of the present invention drives cylinder body shape guide rail or dovetail groove shape guide rail work distribution cut-open view.
Fig. 2 is a hydraulic cylinder form work distribution cut-open view of the present invention.
1. motor among Fig. 1,2. motor forward-reverse switch, 3. worm screw, 4. worm gear, 5. pinion wheel, 6. tooth bar, 7. worktable, 8. cylinder shape guide rail or dovetail groove shape guide rail.
1. motor among Fig. 2,2. fluid-link steering valve, 3. hydraulic pump, 4. hydraulic tube, 5. hydraulic cylinder, 6. lifting chamber, 7. worktable.
Embodiment
In Fig. 1, motor in the pedestal (1) is controlled by the motor forward-reverse switch (2) of external power supply, slow down through worm screw (3) and worm gear (4), worm gear coaxial pinion (5) drives straight-line tooth bar (6), tooth bar is connecting cylinder shape guide rail or dovetail groove shape guide rail (8) motion, makes worktable (7) lifting.
In Fig. 2, the motor of external power supply (1) drives hydraulic pump (3) work, the liquid that produces pressure is by hydraulic tube (4) guiding fluid-link steering valve (2), injects the lifting chamber (6) of hydraulic cylinder (5) respectively through the liquid of switching valve guiding, drives worktable (7) lifting.
Claims (1)
- In the earth instrument of surveying and mapping calibration platform by electric motor driven self-powered platform device, it is characterized in that:External power supply motor (1) is controlled by the power switch (2) of rotating in A, the pedestal, drives worm screw (3) worm gear (4) and slows down, and for dove-tail guided way or cylinder body shape guided way provide power, orders about worktable (7) lifting;The motor of B, external power supply (1) drives hydraulic pump (3) work, and the liquid that produces pressure is by hydraulic tube (4) guiding fluid-link steering valve (2), injects the lifting chamber (6) of hydraulic cylinder (5) respectively through the liquid of switching valve guiding, drives worktable (7) lifting.
