A limit buffer device for limiting the continuous rotation of the rotary shaft system of the photoelectric theodolite

Abstract

A limit buffer device for limiting the continuous rotation of the rotary shaft system of a photoelectric theodolite relates to the field of the photoelectric theodolite, which limits the continuous rotation of the rotary shaft system and elastically buffers the impact when the machine stops. The invention includes a buffer seat, two side baffles, two sliding rods, a limit slider, four compression springs, four adjustment nuts, two stopper rubber caps, two front baffles, two stoppers Electric limit switch, electric limit switch blank and limit stop arm. The electric limit switch stopper is at the position of 1°~3° before the limit stop arm collides with the two stopper rubber caps on the limit slider, and the electric limit switch stopper triggers the two stopper electric limiters switch, and then control the drive motor of the photoelectric theodolite rotary shaft to cut off the power in time, and stop the torque output. The invention can prevent the entanglement of the connecting cables without adding a conductive slip ring, and avoids the problem of damage caused by hard collision of the rotary shaft system when encountering a mechanical stop.

Description

technical field [0001] The invention involves the field of photoelectric latitude and weft meter technology, which specifically involves a limit buffer device for restricting the continuous rotation of photovoltaic latitude and weft rituals. Background technique [0002] Large photoelectric latitudes are used for tracking and measurement of space targets such as aircraft, rockets and artificial satellites. Compared with radar, such as radar, high measurement accuracy and real -time imaging are used, and are widely used in aerospace and other fields. [0003] The rotating shaft system is an important part of the photoelectric latitude and weft meter, which is used to drive the optical system to complete the tracking and capture functions. At present, on the latitude and weft instrument that needs to be continuously rotated in the vertical axis system, a set of conductive slide rings are usually used to connect the horizontal axis system and the vertical axis system to ensure ...

AI Technical Summary

Problems solved by technology

In the photoelectric theodolite whose rotary shaft system does not need continuous rotation, a set of conductive slip rings is also installed, which will not only increase the manufacturing cost of the equipment, but also reduce the working reliability of the photoelectric theodolite.

If only a simple mechanical stop is used to limit the continuous rotation of the theodolite rotary shaft system, thereby preventing the entanglement of the connecting cables on the shaft and under the shaft, but the large impact force during the stop process is likely to cause damage to the equipment
