Ship-based heavy stabilizing platform

Abstract

The invention belongs to the field of machinery manufacturing, and relates to a ship-based heavy stabilizing platform, in particular to structural design of stabilizing platforms with the load being more than 250 kg. The ship-based heavy stabilizing platform comprises a main support, an installation platform, an inner frame, a rolling servo gear motor, a servo control box, a pitching servo gear motor, a spinning top plate, a spinning top A, a spinning top B, an angle sensor A, an angle sensor B, an inclination angle sensor, an inner ring shaft A, an inner ring shaft B, an inner ring gear, an inner ring servo motor gear, an outer ring shaft, a gear shaft, an outer ring servo motor gear and a motor support. The ship-based heavy stabilizing platform has the advantages of being high in bearing capacity, high in stabilizing precision and quick in response. The ship-based heavy stabilizing platform can realize stabilization without a counter weight. Due to the fact that the ship-based heavy stabilizing platform is provided with the inclination angle sensor, drift generated by the spinning tops can be corrected in appropriate time, and the stabilizing precision can be improved.

Description

technical field [0001] The patent of the invention relates to a ship-borne heavy-duty stable platform, in particular to a structural design of a stable platform with a load of more than 250kg, which belongs to the field of machinery manufacturing. Background technique [0002] The stability of the existing stable platform is mainly achieved by using the gyroscope as a sensor to sense the speed of the rotating shaft, thereby controlling the motor to perform reverse compensation motion to achieve stability. There are two types of existing stable platforms, one is to use a torque motor as a drive to achieve Stable, the platform is mostly suitable for a load of about 5-20kg. Although the stable platform is small and light, its load is too small for large transport ships to play a stable role, and when the torque motor is used as the drive of the stable platform, The center of gravity of the load must be controlled within the center of slewing, which is difficult to control and h...

[0002] The stability of the existing stable platform is mainly achieved by using the gyroscope as a sensor to sense the speed of the rotating shaft, thereby controlling the motor to perform reverse compensation motion to achieve stability. There are two types of existing stable platforms, one is to use a torque motor as a drive to achieve Stable, the platform is mostly suitable for a load of about 5-20kg. Although the stable platform is small and light, its load is too small for large transport ships to play a stable role, and when the torque motor is used as the drive of the stable platform, The center of gravity of the load must be controlled within the center of slewing, which is difficult to control and has a small load capacity; the other is a stable platform suitable for large equipment, mainly driven by hydraulic devices, and suitable for loads above 500kg

However, the use of hydraulic drive requires a hydraulic source. Generally, the hydraulic source equipment is relatively large in size, which is not suitable for the stable platform of general medium-sized equipment, and the delay is relatively high.
