The existing jacking transfer mechanism mostly adopts a four-pivot balance jacking structure, four air cylinders in the structure are respectively connected with four pivots of a conveying mechanism, and the four air cylinders are simultaneously lifted through electric control to meet the lifting action of the whole mechanism, so that materials on the working surface of the conveying mechanism are conveyed to the corresponding contact surface.

However, in practical applications, the action time of the air cylinder may be different due to various factors such as whether the air flow in the air path of the air cylinder is stable, the flow rate of the air flow, whether impurities exist in the air flow, and the like, so that the four air cylinders of the jacking transfer mechanism cannot be absolutely synchronized, and when the mechanism is lifted along with the air cylinders, the four supporting points of the supporting and conveying mechanism cannot act in a unified manner. If four fulcrums of the conveying mechanism can not act in a unified mode, the conveying surface on the conveying mechanism is inclined, the conveyed materials swing, detection of the materials by electric elements such as sensors on a production line is affected, and even the materials can fall.

The working process of the embodiment is as follows: when the lifting action is performed in the embodiment, the first jacking device 46 and the second jacking device 47 in the parallelogram jacking mechanisms 4 on the two sides perform jacking actions simultaneously; because the top portion of the first jacking device 46 is connected with the top frame 2, one end of the first parallel rod 43 is rotatably connected with the top frame 2, the top portion of the second jacking device 47 is connected with the top frame 2, and one end of the second parallel rod 44 is rotatably connected with the top frame 2, the first jacking device 46 and the second jacking device 47 on two sides can drive the parallelogram structures on two sides to perform ascending movement when pushing the conveying mechanism 3 to ascend.

The working principle of the embodiment is as follows: in this embodiment, the parallelogram jacking mechanisms 4 on both sides are connected by the first rotating shaft 41 and the second rotating shaft 42, so that the parallelogram jacking mechanisms 4 on both sides form a special cubic structure with respective corresponding surfaces parallel to each other, thereby synchronizing the actions of each point of the parallelogram jacking mechanisms 4 on both sides, and making the conveying surface of the longitudinal conveying mechanism 31 and the horizontal plane formed by the horizontal transmission rods 45 on both sides parallel to each other, and finally realizing that each point of the conveying surface of the longitudinal conveying mechanism 31 is kept horizontal without inclination.

Meanwhile, the first flange portion 481 of the first flange connection block 48 in the present embodiment is rotatably connected to the other end of the first parallel lever 43, the second flange portion 482 of the first flange connection block 48 is rotatably connected to one end of the horizontal transmission lever 45, the third flange portion 483 of the first flange connection block 48 is connected to one end of the first rotation shaft 41, the other end of the first rotation shaft 41 is connected to the other third flange portion 483, the first flange portion 481 and the second flange portion 482 are rotated around the third flange portion 483 while the third flange portion 483 is rotated together with the first rotation shaft 41, the fourth flange portion 491 of the second flange connection block 49 is rotatably connected to the other end of the second parallel lever 44, the fifth flange portion 492 of the second flange connection block 49 is rotatably connected to the other end of the horizontal transmission lever 45, the sixth flange portion 493 of the second flange connection block 49 is connected to one end of the second rotation shaft 42, the other end of the second rotation shaft 42 is connected to the other sixth flange portion 493, the fourth flange portion 491 and the fifth flange portion 492 are rotated around the sixth flange portion 493, and the sixth flange portion 493 is rotated together with the second rotation shaft 42.
