Embodiment Construction
[0041] The following is based on Figure 1 to Figure 4 A preferred embodiment of the present invention is given to illustrate the structural features and implementation methods of the present invention, but not to limit the scope of the present invention.
[0042] In this embodiment, the locking device includes the following parts: azimuth rotation jacking device 2, locking mechanical arm 3, electromagnetic brake 4, locking shaft system 5, unlocking torsion spring 6, locking device base 1 and two-dimensional rotating device 7 And pitch rotation limiter 8. The total weight is less than 1.2KG.
[0043] 1) Locking mechanical arm 3: It is integrally processed and formed from lightweight, high-modulus aluminum-based composite materials, and its bottom is wide for installation; the top protrudes from the baffle to realize the pitch rotation limit; the middle "two wings" protrude It is used for azimuth rotation jacking device installation. In this embodiment, the locking mechanica...

The invention discloses a locking device used for two-dimensional rotating equipment. The locking device of the two-dimensional rotating equipment comprises a locking device base, an orientation rotation tightly-abutting device, a locking mechanical arm, an electromagnetic brake, a locking shafting and an unlocking torsional spring. The locking device is installed on the end face of a base of the two-dimensional rotating equipment, and the locking device locks pitching rotation of the two-dimensional rotating equipment through the top end of the locking mechanical arm and locks orientation rotation through the tightly-abutting device. The locking shafting can be braked through the power-off brake function of the power loss type electromagnetic brake so that the locking device can keep locking the two-dimensional rotating equipment. When braking of the two-dimensional rotating equipment needs to be stopped by the locking device, the electromagnetic brake is powered on, and the braking is stopped. The locking mechanical arm rotates around the locking shafting under the action of the torsion of the unlocking torsional spring and leaves the work range of the two-dimensional rotating equipment in a screwing mode, the power of the electromagnetic brake is then cut off again, and the braking torque makes the locking device keep the unlocking state.
Description
Technical field: [0001] The invention relates to a two-dimensional photoelectric turntable, in particular to a locking device for the two-dimensional photoelectric turntable, which is used for the rotation locking and unlocking of the two-dimensional photoelectric turntable. Background technique: [0002] The space-borne two-dimensional photoelectric turntable can realize the tracking and capture of ground targets and carry out communication operations by driving the two-dimensional large-scale rotation of the photoelectric load. In order to avoid the large-scale rotation of the two-dimensional turntable before power-on work, to protect the shaft system and photoelectric load of the turntable, the two-dimensional photoelectric turntable is locked; before the two-dimensional turntable is powered on, it is necessary to unlock the two-dimensional photoelectric turntable . [0003] Due to the non-repairability of the space-borne two-dimensional photoelectric turntable, the devi...
