Abstract

This invention relates to an auto training leveling instrument, containing a main rule, a supporting plate and a base plate. The main rule and the supporting plate are connected in one end in the same axial and the other two ends of the main rule and the supporting plate are supported by a scalable supporting column and the height of the other two ends is adjustable. The supporting plate in the center is connected with the base plate with a rotary supporting shaft which is provided with rotation scale. The main rule is provided with a power, a motor, a microprocessor, a laser emitter, a photoelectric switch and a U-shaped water pipe filled with light-proof liquid. The photoelectric switches can sense the liquid level changes in the two ends of the water pipe and the microprocessor will give out a clockwise rotation instruction or a reverse rotation instruction according to the result that the switch senses to make the supporting column stretch out and draw back until the photoelectric switches in the two ends of the pipe can sense that the liquid is in the same level. At this moment when the main rule is adjusted to be in a level condition, the laser emitter will start up and emit a focal spot. Rotate the main rule to make the new focal spot connected with the original one to determine the construction level. The utility model has advantages of a simple structure and easy usage.

Description

Automatic adjustment surveyor's staff

Affiliated technical field

The utility model relates to a kind of building operation surveyor's staff.

Background technology

Existing building, the used surveyor's staff of decoration construction are to be embedded in the oil pipe on the chi bubble position by observation to judge and make it the state of being up to the standard with manual adjustment.Its shortcoming is that manual adjustment is not only time-consuming but also require great effort, and particularly accuracy is low, and measurement result is had a greatly reduced quality, and function singleness.

Summary of the invention

At the deficiencies in the prior art, the utility model provides quick, the accurate adjustment of a kind of energy to horizontality, and the surveyor's staff of the horizontal plane function of energy fast measuring one any building operation space arbitrary height is arranged.

The utility model takes solution to be: a main scale, a main scale back up pad and a backing plate three-decker, in the described main scale working power is arranged, power switch, large span also is perfused with the U type water pipe of shading liquid, but each clip of water pipe two ends has the optoelectronic switch that liquid level just changes in the induction tube, optoelectronic switch connects the microprocessor that its induction information is handled, microprocessor connects the generating laser that can penetrate and that is positioned at the main scale two ends again outward and makes motor clockwise or that reverse by microprocessor instruction, motor connects and can make it the support column that is positioned at main scale one end of telescopic movable, and support column is flexible in order to adjust the height change of this (A) of main scale end.The other end of main scale is connected with back up pad with rotating shaft and has fixed highly.Back up pad is connected with beneath backing plate with the rotation fulcrum at mid point again, rotates to be carved with the reading that can show the main scale (comprising back up pad) and the backing plate anglec of rotation on the fulcrum.

The utility model is to use like this: during use, after will it placement stablizing, press the switch power supply switch, the optoelectronic switch at U-shaped water pipe two ends is responded to the liquid in pipe horizontality immediately, the shading liquid that the optoelectronic switch of holding as A is exceeded hides to cut off and opens, and illustrates that this (A) end is low, and those (B) hold high.Microprocessor information in view of the above sends clockwise instruction to motor, the driving support column extends, progressively improve the height of this (A) of main scale end, till shading liquid falls back to the two ends equal height in optoelectronic switch is sensed pipe, the main scale of this moment is calibrated for horizontality, and the generating laser at two ends is opened immediately.On the contrary, when exceeding, motor then reverses, and main scale is calibrated for horizontality equally when the other end (B end).When need are measured the horizontal plane of working-yard one arbitrary height, only need the focus of two ends laser instrument projection is coupled to a horizontal line, then main scale is rotated respective angles, can draw two projection focuses in addition again, all focuses connections can be drawn required surface level.

Compared with prior art, the beneficial effects of the utility model are to make the horizontal survey of building, decoration construction realize robotization, and are time saving and energy saving, accurately quick, and simple in structure, easy to use.

Among the figure: 1 backing plate, 2 rotation fulcrums, 3 anglec of rotation readings, 4 back up pads, 5 rotating shafts, 6 main scales, 7 microprocessors, 8 power supplys, 9U shape water pipe, 10 optoelectronic switches, 11 generating lasers, 12 power switches, 13 motors, 14 support columns

Embodiment

As shown in Figure 4, the utility model is lain against on the support body with backing plate (1), by electric shock source switch (12) start-up system work.The optoelectronic switch (10) at U-shaped water pipe (9) two ends in the main scale (6) is responded to the water level at U-shaped water pipe (9) two ends immediately.If the water level that the optoelectronic switch (10) of A end is exceeded hides to cut off and opens, the height that this (A) of main scale end is described is low, and those (B) hold high, and microprocessor (7) sends clockwise instruction to motor (13) in view of the above, drive support column (14) elongation, progressively improve the height of this (A) end.(opposite, then reverse, the withdrawal support column reduces this (A) end height), when the optoelectronic switch of bringing up to two ends (10) is all sensed two ends when being in same horizontality, microprocessor (7) instructs motor (13) to stop operating immediately, and promptly Ci Shi main scale (6) is calibrated for horizontality.Then, microprocessor (7) starts generating laser (11), and rotation main scale (6) links each laser projections focus can draw a surface level.
