Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1-3, the utility model provides a two-way atress supporting mechanism, including backup pad 6, with first connecting rod 7, the frame 1 of backup pad 6 rigid coupling, fix fixed axle 4 in frame 1, rotate to be connected second connecting rod 5 on the fixed axle 4, be located the drive unit 2 of frame 1 bottom, the third connecting rod 3 that connects with drive unit 2, the articulated fourth connecting rod 9 of 7 other ends of first connecting rod, second connecting rod 5, third connecting rod 3, fourth connecting rod 9 are through the articulated connection of same axis of rotation.
The driving unit is a cylinder or a motor and can drive the third connecting rod to move up and down. A first rotating shaft 8 is arranged between the first connecting rod 7 and the fourth connecting rod 9, and the first connecting rod 7 and the fourth connecting rod 9 are hinged to the first rotating shaft 8. The connecting rod mechanism is characterized by further comprising a second rotating shaft 10, one end, far away from the fixed shaft 4, of each of the two connecting rods is connected to the corresponding second rotating shaft 10 in series, and the third connecting rod 3 and the fourth connecting rod 9 are connected to two sides of the corresponding second rotating shaft 10 in a rotating mode respectively.
The fixed shaft 4 is fixed between the two parallel racks 1, and the joint of the first connecting rod 7 and the first rotating shaft 8 is located at the position of the same horizontal line in a vertical state, so that the fixed shaft 4, the second connecting rod 5, the first rotating shaft 8, the fourth connecting rod 9 and the second rotating shaft 10 can rotate to the same horizontal line, and the stress mechanism can transmit stress to bear the maximum stress in the state.
Wherein, 1 top in frame sets up hollow limiting plate 11, will control the structure of linking and strengthen, plays the limited action of position simultaneously, fourth connecting rod 9 is located in hollow limiting plate 11, guaranteed that the fourth connecting rod is the biggest to rotate to vertical state, on the connecting axle of second connecting rod 5 and third connecting rod 3 was in the line of the rotation axis of second connecting rod 5 and third connecting rod 3 under this state, the backup pad just can the atress be the biggest.
When a large force needs to be borne, the cylinder 2 pushes the first connecting rod 7 to extend out, so that the second connecting rod 5 and the third connecting rod 3 rotate upwards around the rotating shaft, and stop when the connecting shaft of the second connecting rod 5 and the third connecting rod 3 is located on the connecting line of the rotating shafts of the second connecting rod 5 and the third connecting rod 3, so that the rotating shaft center of the second connecting rod 5, the rotating shaft center of the third connecting rod 3 and the rotating shaft center of the connection of the second connecting rod 5 and the third connecting rod 3 are on the same straight line, at the moment, the stressed supporting plate 6 can bear large forces in two directions of vertical downward direction and horizontal rightward direction, the magnitude of the stress depends on the strength of the rotating shaft and the strength of the connecting rods, and a stable state is kept, at the moment, the force received by the supporting plate 6 is transmitted to the rotating shaft and the connecting rods, the stress of the cylinder 2 is reduced, and the service life of the cylinder 2 is protected.
When the stress is not applied, or the stress state is required to be broken, the second connecting rod 5 can be retracted, so that the first connecting rod 7 and the stress supporting point are retracted to the position where the stress is not applied, and the space is reserved.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
