In the working process of the high-reliability swing table, the swinging assembly 3 can change the inclination angle of the load platform 1 relative to the support frame 2 through swinging of the swinging assembly; namely, the change of the inclination angle of the load platform 1 relative to the support frame 2 is realized by utilizing the rotation of the inclined surface of the inclined structural member 301 under the action of the component rotation mechanism 302; thus, the swing simulation of the load platform 1 and the structure thereon is realized.
As will be appreciated from a comparison of fig. 2 and 3 in conjunction with this application, the central axis in fig. 2 requires the shafting structure closest to the load, plus the weight of the load, and the outermost axis requires the shafting structure of the two axes closest to the load and intermediate to the load.

The swing tables currently used on the ground are generally tested using a six degree of freedom swing table. However, the system has higher price and weaker protection of most structures, is difficult to run outdoors for a long time in all weather, and the single six-axis swinging table cannot complete the function of continuous rotation unless a turntable system is additionally added.

In use, the control of swinging is controlled by the component swinging mechanism 302 of the swinging component 3, when only swinging motion is desired and rotation of the bearing plate 11 is not desired, the bearing swinging mechanism is added to the load platform 1, and at the moment, the rotation of the component swinging mechanism 302 can be counteracted by the reverse rotation of the bearing swinging mechanism, so that the aim of completely decoupling the heading (rotation) of the bearing plate 11 from the swinging component 3 is achieved.

Referring to fig. 6 to 8, fig. 6 is a first schematic state diagram of the high-reliability swing table provided in the embodiment of the present application, fig. 7 is a second schematic state diagram of the high-reliability swing table provided in the embodiment of the present application, and fig. 8 is a third schematic state diagram of the high-reliability swing table provided in the embodiment of the present application.
In some embodiments, as shown in fig. 6, the swing assembly 3 has two swing units, namely, a first swing unit 31 and a second swing unit 32, and the swing simulation effect of the swing assembly 3 is realized by combining the first swing unit 31 and the second swing unit 32; as shown in fig. 7 and 8, the first swing unit 31 includes a first tilting structure 311 and a first assembly swing mechanism, and the second swing unit 32 includes a second tilting structure 321 and a second assembly swing mechanism, and the swing control is performed by both the first assembly swing mechanism and the second assembly swing mechanism.
In this embodiment, the first rotating unit 31 is located at an upper layer, the second rotating unit 32 is located at a lower layer, and at this time, a second component rotating mechanism in the second rotating unit 32 is installed on the support frame 2, the second component rotating mechanism is connected to the second tilting structure 321, a first component rotating mechanism in the first rotating unit 31 is installed on the second tilting structure 321, and the first component rotating mechanism is connected to the first tilting structure 311.
In some embodiments, the above-described assembly swing mechanism is similar to the carrier swing mechanism, and is also employed as a swing speed reducer, where the first assembly swing mechanism is the first swing speed reducer 312 and the second assembly swing mechanism is the second swing speed reducer 322.

Referring to fig. 9 and fig. 10, fig. 9 is a schematic structural diagram of an inclined structural member according to an embodiment of the present application, and fig. 10 is a schematic structural diagram of an assembly turning mechanism according to an embodiment of the present application.
More specifically, for the inclined structural member 301 (for example, the first inclined structural member 311 and the second inclined structural member 321), which has a first mounting portion 3011 and a second mounting portion 3012, taking the second mounting portion 3012 as an example, the first mounting portion 3011 is inclined with respect to the second mounting portion 3012, and at this time, the inclination angle of the inclined structural member 301 is the inclination angle of the first mounting portion 3011 with respect to the second mounting portion 3012; wherein, the first mounting part 3011 is used for being connected with the component revolving mechanism 302 of another revolving unit upwards, and the second mounting part 3012 is used for being connected with the component revolving mechanism 302 of the present revolving unit downwards.
For the assembly swing mechanism 302 (e.g., the first swing speed reducer 312, the second swing speed reducer 322), it has an outer race 3021 and an inner race 3022; wherein the outer ring 3021 is adapted to be connected downwardly to the support frame 2 or to the first mounting portion 3011 of the tilting structure 301 of the other swivel unit, and the inner ring 3022 is adapted to be connected upwardly to the second mounting portion 3012 of the tilting structure 301 of the present swivel unit.

In this embodiment, the solution proposes to use two inclined structural members, wherein the inclined structural members are combined with the rotary speed reducers one by one, that is, the first inclined structural member 311 is combined with the first rotary speed reducer 312, and the second inclined structural member 321 is combined with the second rotary speed reducer 322; therefore, the swinging table system capable of realizing the double angle of any inclined plane inclination angle a is formed, the function of three-axis translation in the swinging table with six degrees of freedom is omitted, and the swinging table system is more suitable for ground simulation of a floating laser radar system.
It should be explained that the floating type wind-measuring laser radar is an offshore floating wind-measuring system which is carried on a buoy by the coherent Doppler wind-measuring laser radar and is matched with a high-precision real-time attitude measuring system to correct the swing of the buoy along with sea waves in real time. Whether real-time correction and swing can be performed on the sea or not, and how the correction algorithm is the key of wind measurement precision of the system. The coherent Doppler wind-measuring laser radar is a remote sensing type laser wind-measuring device for measuring the moving speed of tiny particles in the atmosphere by using pulse laser. The measurement height of small devices is typically several hundred meters. The measurement is generally required to be firmly fixed, and accurate leveling and positioning are performed to ensure the measurement accuracy.
By way of example, with an angle of inclination a of 8 degrees, the system has a maximum roll angle of 16 degrees, which can cover a substantial portion of an offshore roll environment.
It should be noted that the tilt angle can also be adjusted as needed to accommodate similar applications where the simulated angle of inclination of the buoy is mainly centered within 15 degrees, the period is about 5-20 seconds, the sway directions are different, and the heading is slowly changed over a wide range.
In this embodiment, it will be appreciated that in conjunction with fig. 4 and 5, the drawings show two discs with 8 degree tilt with bearing structure therebetween for relative rotation. When the two tilting directions are completely opposite, the tilting is equivalent to cancellation, and the top surface is in a horizontal state, as shown in fig. 6; when the tilt directions are the same, the tilt angles are fully superimposed, and the top surface is 16 degrees of tilt angle, as shown in fig. 7 and 8. By controlling the relative positions of the two disk rotations, the angle of inclination of the top surface can be controlled to within any 16 degrees.
Besides, the swing table uses a firm and durable swing worm speed reduction bearing structure with strong load capacity, and is driven by a closed-loop servo motor, so that the rotation speed and the rotation position of the upper swing speed reducer and the lower swing speed reducer can be accurately controlled, the characteristics of accurately controlling the swing angle, direction, period and the like are realized, and the top swing speed reducer is mainly used for controlling the course of a load platform.
In some embodiments, the inclined structural member 301 and the assembly revolving mechanism 302 are hollow structures, that is, each inclined structural member 301 and each revolving speed reducer are hollow structures, and an electrically conductive slip ring is accommodated in the middle, so that electric power and control signals can be sent to the position of the load platform 1 step by step without being influenced by continuous rotation of each stage in the middle. It is also possible to provide the path of the power and control signals to the load of the load platform 1.
In some embodiments, the load platform 1 is provided with lightening holes and when the load platform 1 is not tilted, the centre of symmetry of the load platform 1 is located on the axis of rotation of the swivel assembly 3.
In the embodiment, various rotary speed reducers are mature common mechanical bearing structures, have high load capacity on axial force, radial force and overturning force, have stable and reliable performance, have IP66 in self protection, and can be used in an outdoor environment for a long time. The worm speed reducer is arranged in the rotary speed reducer, the speed reduction ratio is adjustable, the matching precision is high, and the torque requirement on the driving motor is greatly reduced. And the weight of the load is not placed on the driving source (motor), but is supported by the bearing structure, and the power failure of the motor does not affect the supporting structure.
