Abstract

The invention relates to a mechanical buffering and limiting device. The mechanical buffering and limiting device comprises a pitch shafting rotary shaft, a stand column supporting the rotary shaft, a bidirectional collision block, single-end spring buffering pieces and double-end spring buffering pieces, wherein the bidirectional collision block is fixedly connected with the pitch shafting rotary shaft through a screw, the two single-end spring buffering pieces and the two double-end spring buffering pieces are installed on the end face of the stand column supporting a pitch shafting according to the positions of limiting angles, and at the positions of the two limiting angles, one end of the bidirectional collision block is made to strike one single-head spring buffering piece, the other end of the bidirectional collision block is made to strike the double-end spring buffering piece which is arranged on the stand column supporting the rotary shaft, the included angle between the single-end spring buffering piece stricken by one end of the bidirectional collision block and the double-end spring buffering piece stricken by the other end of the bidirectional collision block is 180 degrees in the circumferential direction, and thus a moment of couple is formed to buffer the rotation of the pitch shafting rotary shaft. The mechanical buffering and limiting device is suitable for safety protection of the rotary pitch shafting of a photoelectric theodolite. According to the mechanical buffering and limiting device, the rotation of the rotary shaft is prevented through the moment of couple, impact to the pitch shafting is avoided, and the rotation precision of the pitch shafting is guaranteed.

Description

technical field [0001] The invention relates to the safety protection of the pitching and rotating shaft system of a photoelectric theodolite, specifically a mechanical buffering and limiting device. Background technique [0002] When the pitching axis of the photoelectric theodolite is out of control, in order to ensure the rotation accuracy of the pitching axis of the photoelectric theodolite and the safety of the photoelectric detection equipment mounted on it, a device is required to buffer and brake the high-speed rotating shaft of the pitching axis. The current mechanical limit measure is to fix a one-way impact block on the rotation axis of the pitch shaft system, and install a spring buffer device on the end face of the column supporting the rotation axis according to the limit angle (usually -5° and +185°). , to realize the buffer braking protection of the photoelectric theodolite pitching axis. Since the position of buffer impact in this structural device deviates...
