Abstract
The utility model discloses a kind of tripod be convenient to surveying instrument and flattened neutralization, comprise frame head and three frame legs, three described frame legs are hinged on below frame head, and frame leg comprises internal frame and outrigger, and internal frame can move in outrigger; Be provided with extension adjustment device at the middle part of described outrigger, described extension adjustment device comprises turning axle, gear and handle; One end of turning axle is inserted and can around own axis in hole from the hole that outrigger sidewall is opened; Gear and handle are separately fixed at the two ends of turning axle, and handle is positioned at outside outrigger; Internal frame is processed with tooth bar along its length, and rack and pinion engages, and when making up time or be rotated counterclockwise handle, gear rotates thereupon thus is with carry-over bar to move up or down.The utility model utilizes extension adjustment device crane leg to carry out instrument and flattens precisely convenient, in conjunction with the destruction because instrument reverses to existing level during circular bubble minimizing centering, improve surveying instrument centering leveling speed and the precision of guarantee arrangement.
Description
Technical field
The utility model relates to a kind of tripod be convenient to surveying instrument and flattened neutralization, and this tripod is convenient to the arrangement of surveying instrument, can improve the Efficiency and accuracy that surveying instrument is settled.
Background technology
No matter be traditional transit or now widely used total powerstation, measurement in all need in and leveling, centering is use transit and total powerstation to carry out a step of crucial importance and crucial when angle etc. is measured with leveling, and it directly has influence on the precision of measurement.But, because leveling and centering two operations influence each other result, not only precise alignment but also strictly flatten be accomplished, just must repeatedly carry out, not only time-consuming but also forbidden, bring very large difficulty to operator.
At present, the leveling of instrument is completed by the lifting of foot rest usually, existing surveying instrument settles tripod (as shown in Figure 1) to be by hand steered firmly outrigger, the length that thumb pins internal frame top expansion bracket leg carries out instrument leveling, this mode inconvenient operation, and the stroke of wayward tripod frame leg.Meanwhile, the tripod end face after frame stands does not measure up, and when mobile transit carries out centering on out-of-level tripod end face, instrument can be caused to twist, thus destroy existing leveling, need again centering and leveling.But whether level is judged by staff's naked eyes the frame head of existing surveying instrument arrangement tripod, usually can cause flattening operation again owing to judging inaccurate.
To sum up, study a kind of be conducive to surveying instrument to neutralization leveling tripod be necessary.
Summary of the invention
For the defect existed in above-mentioned prior art or deficiency, the purpose of this utility model is, provides a kind of and is convenient to the tripod of surveying instrument to neutralization leveling.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be solved:
Be convenient to the tripod of surveying instrument to neutralization leveling, comprise frame head and three frame legs, three described frame legs are hinged on below frame head, and frame leg comprises internal frame and outrigger, and internal frame upper end to be arranged in outrigger and can to move in outrigger; Sidewall on outrigger is provided with fixed screw, and the end of fixed screw is positioned at outrigger and presses the sidewall of internal frame; Be provided with extension adjustment device at the middle part of described outrigger, described extension adjustment device comprises turning axle, gear and handle; Wherein, one end of described turning axle is inserted and can around own axis in hole from the hole that outrigger sidewall is opened; Described gear and handle are separately fixed at the two ends of turning axle, and described handle is positioned at outside outrigger; Internal frame is processed with tooth bar along its length, and rack and pinion engages, and when making clockwise or be rotated counterclockwise handle, gear rotates thereupon thus is with carry-over bar to move up or down.
Further, described frame head upper surface is provided with circular bubble.
Further, the length of described tooth bar is 20cm ~ 40cm.
The utility model is compared with existing tripod, utilize extension adjustment device, the flexible of frame leg can not only be realized easily, and easily control its stroke, be easier to the leveling of instrument, simultaneously, be equipped with the circular bubble on frame head, make the adjustment of tripod more flexibly, conveniently, and regulate precisely, ensure that surveying instrument can be avoided because destroying existing leveling when traverse measurement instrument carries out centering on out-of-level tripod end face, thus improve transit to the speed of neutralization leveling and precision.
Accompanying drawing explanation
Fig. 1 is the tripod structure schematic diagram that surveying instrument of the present utility model is settled.
Fig. 2 is the sectional view of the frame leg being provided with extension adjustment device.
Below in conjunction with the drawings and specific embodiments, further explanation is explained to the utility model.
Embodiment
As shown in Figure 1, the tripod be convenient to surveying instrument and neutralization is flattened of the present utility model, comprise frame head 1 and three frame legs 2, described three frame legs 2 are hinged on below frame head 1, frame leg 2 comprises internal frame 3 and outrigger 4, and internal frame 3 upper end to be arranged in outrigger 4 and can to move in outrigger 4; Sidewall on outrigger 4 is provided with fixed screw 5, the end of fixed screw 5 is positioned at outrigger 4 and presses the sidewall of internal frame 3, plays fixation thus, and the relative position between the internal frame after leveling 3 and outrigger 4 is no longer changed.
Flexible convenient and accurate in order to adjusting bracket leg, the tripod of surveying instrument to neutralization leveling of being convenient to of the present utility model adds extension adjustment device.Be provided with extension adjustment device at the middle part of outrigger 4, described extension adjustment device comprises turning axle 6, gear 7 and handle 9; Wherein, insert in the hole that one end of described turning axle 6 is opened by outrigger 4 sidewall, its size coordinate with hole do not affect it can around own axis in hole; Described gear 7 and handle 9 are separately fixed at the two ends of turning axle 6, and wherein, handle 9 is positioned at outside outrigger 4; Internal frame 3 is processed with tooth bar 8 along its length, tooth bar 8 engages with gear 7, when this makes clockwise or is rotated counterclockwise handle 9, gear 7 rotates thereupon thus drives bar 8 to move up or down, then realizes internal frame 3 and moves relative to outrigger 4 that to realize frame leg 2 flexible.
Optionally, the length of tooth bar 8 is 20 ~ 40cm.
Optionally, frame head 1 upper surface is provided with circular bubble 10, and to ensure the level of frame head 1, thus the instrument caused because frame head is out-of-level when avoiding the surveying instruments such as mobile transit reverses.
The utility model is when reality uses, first tripod of the present utility model is arranged on measurement point and carries out rough centering, then the fixed screw 5 on frame leg 2 is unscrewed, clockwise or be rotated counterclockwise handle 9, gear 7 is rotated thereupon thus is with carry-over bar 8 to move up or down, then utilize internal frame 3 to realize frame leg 2 relative to the motion of outrigger 4 to stretch, according to situation adjusting bracket leg 2, thus the circular bubble bubble realized on circular bubble 10 that frame head 1 upper surface installs and instrument base is placed in the middle, completes centering and the leveling of instrument.
