TECHNICAL FIELD

[0001] The utility model relates to level technology field especially is a kind of level with compensator limiting automatic alarm mechanism. BACKGROUND

[0002] Automatic leveling instrument is a kind of instrument for measuring ground elevation, for measuring the relative height difference of each point in a certain range. Its use method is to observe the height data of each target tower scale on the ground through the ocular group, and the relative height difference of each target point is obtained by calculation. The compensator in the automatic leveling instrument is one of the core components, and its function is: when the level is slightly inclined, the front optical axis will be slightly inclined, which will cause the measurement data to be inaccurate. At this time, the pendulum group of the compensator will move relative to the front optical axis under the action of gravity, so that the optical reference axis of the level is corrected to the state of being parallel to the horizontal plane, so that the tower scale reading when the optical axis is horizontal is obtained quickly, and the accuracy of the measurement data is ensured.

[0003] When the limiting mechanism of the traditional automatic leveling instrument compensator contacts the limiting column, there is no effective measure to remind the user whether the compensator is in the effective working interval, and the operator cannot judge whether the automatic leveling instrument is in normal working state.

[0006] A limiting column is fixedly arranged on the top of the compensator part.

[0007] A limiting mechanism is arranged above the compensator part and passes through the limiting column, and a conductive copper sheet is arranged in the limiting mechanism. The conductive copper sheet is connected with an alarm, and when the limiting column contacts the limiting mechanism, the circuit is closed, and the alarm gives an alarm. When the limiting column does not contact the limiting mechanism, the circuit is open, and the alarm does not give an alarm.

[0008] Further, the compensator part comprises a swing frame group, a plurality of suspension wires and a pendulum group, and the swing frame group is fixedly arranged on the level.

[0009] Further, the pendulum body group is fixed below the pendulum frame group by the suspension wire, and when the level is inclined, the pendulum body group swings around the pendulum frame group.

[0010] Further, the limiting mechanism comprises a limiting plate.

[0011] Further, the limiting column passes through the limiting plate.

[0012] Further, the inner wall of the limiting plate is provided with a ring of conductive copper sheets.

[0013] Compared with the prior art, the utility model has the following beneficial effects: when the level is slightly inclined, under the action of gravity, the suspension wire pulls the pendulum body group to slightly swing around the pendulum frame group, and the front optical axis is relatively moved, so that the optical reference axis of the level is corrected to the state of being parallel to the horizontal plane; when the inclination angle of the level is too large, the limiting column touches the limiting mechanism, the alarm circuit is closed, an alarm is sent, and the user is timely reminded when the compensator of the automatic leveling level is broken, the suspension wire is broken, the compensator limiting column contacts the limiting mechanism, and the compensator fails.
