The invention provides an electro-hydraulic mixed full-angle pitching mechanism of an ultra-wide flat plate unit, which also has the following innovation points:
the driving rod in the mechanism can realize locking in an initial state and a lifting in-place state, and a triangular area formed by a third node, a fourth node and a fifth node after locking just covers the projection of the central axis of the core of the ultra-wide flat plate unit, so that the theoretical gravity center of the ultra-wide flat plate unit is stable.
The lifting driving mechanism of the pitching mechanism is hydraulically driven, can provide larger thrust force relative to the driving of the electric cylinder, has smaller space volume, is easy to synchronize with the hydraulic locking cylinders for the fifth node and the seventh node, has excellent reliability, and can ensure the loading of the heavier ultra-wide flat plate unit.
The pitching mechanism only has one hydraulic cylinder to drive and lift, so that the driving devices are few, and the reliability of the mechanism is improved.
The ultra-wide flat plate unit is driven by the servo motor integrated in the space area of the component rod, the space integration is high, and the servo driving system is composed of a gear system and has self-locking capability, so that the ultra-wide flat plate unit can reside at any position within the working angle range, the angular speed driving control of the ultra-wide flat plate unit can be realized on the basis of optimizing a servo transmission structure, and the capability potential of pitching is huge.
The pitching mechanism of the invention adopts hydraulic drive, can arrange two groups of identical mechanisms in the width direction (namely 8 meters direction) parallel to the ultra-wide flat plate unit, is easy to realize the synchronization of the two groups of mechanisms, and has no problem of difficult synchronization of the driving of a servo motor.

Detailed Description
The invention is further described below with reference to the drawings and examples. All of the features disclosed in all of the embodiments of this specification, or all of the steps in any method or process disclosed implicitly, except for the mutually exclusive features and/or steps, may be combined and/or expanded and substituted in any way.
In the process of solving the technical difficulty in the background, the invention finds that the following technical problems exist: in fig. 1, a represents the included angle between the ultra-wide flat plate unit and the plumb face, b represents the height of the ultra-wide flat plate unit, here 2.5 meters, c represents the thickness of the ultra-wide flat plate unit, here 0.6 meter, d represents the height of the ultra-wide flat plate unit from the bottom surface, here 0.7 meter, and e represents the height of the ultra-wide flat plate unit from the bottom surface after being lifted in place, here 1.96 meters. The ultra-wide flat panel unit is defined herein as a large flat panel functional unit having a height b, a thickness c, and a width greater than 8 meters, and what units are specifically disposed within the functional unit's spatial volume may be determined according to the specific task requirements of the device. The ultra-wide flat unit needs to design a mechanism in a height space d from the ground, and realizes the space posture conversion shown in fig. 1, and the lowest point of the ultra-wide flat unit in the conversion process is required to be always higher than d. Because the ultra-wide flat plate unit is heavy, the high-altitude rotation center of the ultra-wide flat plate unit needs to be designed in the core of the unit in consideration of the high pitching transmission response speed, the eccentric transmission problem is reduced to the greatest extent, and the response speed and the stability of a transmission system are improved. The angle a in fig. 1 ranges from 0 deg. to 90 deg., and the ultra-wide flat unit needs to stay in any position within this angle range.
The posture adjustment of the existing ultra-wide flat plate unit is divided into two main steps: firstly, lifting the unit by a lifting mechanism; second, the driving unit is rotated around the core by installing the driving device at the unit core. Analysis shows that the mechanism of the prior art scheme is usually to directly fix the core of the ultra-wide flat plate unit and directly drive the core to rotate, but cannot meet the lifting requirement. In the case of a lifting in the spatial range of the height d from the floor and satisfying the restrictions in fig. 1, the set of means for arranging the drive in the unit core is not seen temporarily.
The embodiment of the invention provides a set of electrohydraulic hybrid driving transmission mechanism capable of enabling an ultra-wide flat plate unit to pitch at all angles in a pitch dimension. The mechanism mainly comprises an active rod 103, a component rod 104, a passive rod 101 and a hydraulic cylinder 102.
In the initial state of the mechanism, as shown in fig. 2a, the passive lever 101 is formed by a triangle area formed by the first node 201, the sixth node 206 and the seventh node 207, and at this time, the first node 201 and the seventh node 207 on the passive lever 101 are locked on the bottom surface 1, and the sixth node 206 is locked in a spatial position. Further, in the triangle area formed by the third node 203, the fourth node 204, and the sixth node 206, since the third node 203 is fixed to the bottom surface 1 and the sixth node 206 has spatially locked in the previous sequence description, it is inferred that the spatial position of the fourth node 204 is locked, and thus the member bar 104 including the fourth node 204 and the sixth node 206 is spatially locked. The mechanism is not stressed by the hydraulic cylinder 102 throughout its initial state.
When the mechanism needs to be lifted, the seventh node 207 is unlocked (the unlocking device and the hydraulic cylinder are in the same hydraulic control system), at this time, the driving rod 103 can rotate around the third node 203, after the seventh node 207 is unlocked, the hydraulic cylinder 102 supplies liquid to push the hydraulic cylinder 102 to lengthen, one end of the hydraulic cylinder 102 is fixed at the second node 202, one end is fixed at the sixth node 206, and as the hydraulic cylinder 102 lengthens, the component rod 104 starts to move upwards, and finally the mechanism moves to the state shown in fig. 2 b.
When the mechanism is lifted to the state as in fig. 2b, the fifth node 205 of the active lever 103 is locked to the bottom surface 1, and at this time, the fourth node 204 is also locked spatially since both the third node 203 and the fifth node 205 on the active lever 103 are locked. The spatial triangle formed by the first node 201, the fourth node 204 and the sixth node 206 achieves locking due to the spatial locking of the first node 201 to the bottom surface and the fourth node 204, and thus the spatial position locking of the component bar 104 including the fourth node 204 and the sixth node 206 is accomplished.
After the component rod 104 is locked at the space position, a servo system in an area surrounded by the pentagonal outline of the component rod 104 realizes the rotary driving of the ultra-wide flat plate unit core, namely, a servo driving system consisting of a set of shaft, a gear and a servo control motor is arranged in the space volume of the component rod 104, and the system drives a central shaft positioned in the ultra-wide flat plate unit core to perform circumferential rotation.
Through the steps, the electro-hydraulic mixed full-angle pitching mechanism of the ultra-wide flat plate unit realizes the lifting and rotating functions of the ultra-wide flat plate unit.
In the specific implementation process, the hydraulic cylinder pushes the component rod 104 to rise, so that the ultra-wide flat plate unit reaches a preset spatial position of the mechanism, after the fifth node 205 is locked, the lifting mechanism realizes spatial position locking, and a servo system arranged in the component rod 104 drives the ultra-wide flat plate unit to rotate around the core of the ultra-wide flat plate unit. The mechanism is locked and then the strength is improved, so that good support can be provided for pitching transmission of the ultra-wide flat plate unit, meanwhile, the space volume of the mechanism rod is larger, and a larger servo motor, gear transmission or other control units are convenient to arrange and are used for matching the weight increase of the ultra-wide flat plate unit.
The ultra-wide flat plate unit electrohydraulic mixing full angle pitching mechanism designed and applied according to the invention is shown in fig. 4, 5 and 6. The mechanism reduces the number of driving hydraulic cylinders to two by applying the invention four times in the width direction of the ultra-wide flat plate unit. Due to the parallel application of the invention in the width direction, the strength of the width dimension of the ultra-wide flat plate unit is greatly increased, the thickness of the component rod is increased, the space volume available for designing a servo system is increased, and the load potential of the mechanism is increased.
