Gyroscope and gravity bistable cradle head

Abstract

The invention discloses a gyroscope and gravity bistable cradle head, which is used on a rocking carrier. The gyroscope and gravity bistable cradle head has the greatest characteristics that a single-axis gyroscope and a moment motor on a vertical axis and a horizontal axis in the cradle head can be used for carrying out precise gyroscope stabilization at ordinary times, and the error is within + / -0.5degree; during power loss or gyroscope system faults, the cradle head can be automatically changed into a gravity stabilizing mode, and the error does not exceed + / -5 degrees by a sea trial; especially when the 5-degree oscillation is acted on the left and right directions of a mirror axis, almost no influence is caused on observation and display. A saddle weight is respectively arranged on the vertical axis direction and the horizontal axis direction in the gyroscope and gravity bistable cradle head, the pitching motion of the cradle head and the front and back oscillation of a bearing plate are combined, only the top of the whole machine is swung, the appearance is attractive, the top is provided with a water-proof cover, and the water resistance is especially good. The gyroscope and gravity bistable cradle head is suitable for installing and using all rocking carriers, especially suitable to use on a rocking ship.

Description

Technical field: Background technique: [0001] The pan / tilt is a mechanical device that can rotate horizontally and tilt up and down for carrying devices such as observers. There are many commercially available, such as ordinary 301 pan / tilts. However, if this type of pan / tilt is placed on a shaking ship or airplane On the car, because the carrier is shaking all the time, it cannot work normally. For this reason, it is necessary to add a stable platform under the gimbal to isolate the interference of external forces. The current stable platform can be divided into two types, one is gravity stabilized Method, such as the patent that I applied for several years ago: Marine Night Instrument Stabilization Platform (Patent No.: ZL2000520117451X) It utilizes two horizontal rings that are connected with each other with shafts, the shaft of the outer ring is worn on the support, and the shaft of the inner ring is connected with the outer ring. The ring is vertical. A platform is set ...

[0001] The pan / tilt is a mechanical device that can rotate horizontally and tilt up and down for carrying devices such as observers. There are many commercially available, such as ordinary 301 pan / tilts. However, if this type of pan / tilt is placed on a shaking ship or airplane On the car, because the carrier is shaking all the time, it cannot work normally. For this reason, it is necessary to add a stable platform under the gimbal to isolate the interference of external forces. The current stable platform can be divided into two types, one is gravity stabilized Method, such as the patent that I applied for several years ago: Marine Night Instrument Stabilization Platform (Patent No.: ZL2000520117451X) It utilizes two horizontal rings that are connected with each other with shafts, the shaft of the outer ring is worn on the support, and the shaft of the inner ring is connected with the outer ring. The ring is vertical. A platform is set on the inner ring, and a weight is hung below it. Gravity is used to stabilize the platform. It has a simple structure, is cheap, and does not require electricity. However, in sea trials, it is found that there is inertial force when the ship swings. , so the stability accuracy can only reach within ±5°. If the 5° acts on the observer in the left and right directions, the influence will be small, but it will have a greater influence on the mirror axis direction, which often makes the target object break away from the display. , the lower frame, but no matter what, it is better than shaking 20-30° without gravity stability, so the current magnetic compass on the ship, etc., all use this stabilization method

The other is gyro stabilization, which has high precision and the stability can reach within 0.5°, but the structure is more complicated, the calculation is difficult, and the price is expensive. Whenever there is a power failure or failure, it will lose its stabilizing effect. To manufacture a stable pan / tilt, it is necessary to Make the stable platform and the cloud platform together. At present, the GR-163 marine dual-axis gyro stable platform produced by Beijing Guanzhong Jingyi Technology Co., Ltd. and the TN10 marine self-stabilizing platform produced by Guangzhou Huazhihang Ship Parts Co., Ltd. are the , but they are all dual-axis gyro-stabilized, once the power is lost or malfunctioned, they cannot be used
