Detailed ways

As shown in FIG. 1 , the utility model discloses a stable lifting and translation device, which includes a support platform 1, a translation plate 2, a support arm 3 for connecting the support platform 1 and the translation plate 2, and a support arm 3 arranged on the A drive mechanism 4 on the support platform 1 and used to drive the support arm 3 to rotate, the support arm 3 is provided with a leveling mechanism capable of keeping the translation plate 2 in a horizontal state all the time, and the support arm 3 is two. They are respectively arranged on both sides of the support platform 1 and the translation plate 2. The drive mechanism 4 can drive the support arm 3 to rotate, so that the translation plate 2 can be lifted and lowered. Due to the leveling mechanism provided in the support arm 3, it can Realize that the translation plate 2 is always in a horizontal state, so as to ensure that the items carried on the translation plate 2 will not fall, thereby realizing the high and low transfer of the items, and the structure is simple, does not occupy too much space, and the cost is low, and it is convenient to control the machine. operate.

In this technical solution, the leveling mechanism includes a first fixed gear 51 placed in the support arm 3 and fixedly connected to the side of the support platform 1 at one end, and the other end placed in the support arm 3 and the translation The second fixed gear 52 fixedly connected to the side of the plate 2 and a plurality of transmission gears 53 placed in the support arm 3 and connected to the first fixed gear 51 and the second fixed gear 52, the number of the transmission gears 53 is 2N+1, and N≥0, the size, shape, number of teeth and other gear parameters of the transmission gear 53, the first fixed gear 51 and the second fixed gear 52 are all the same. When working, the drive mechanism 4 drives the support arm 3 to rotate , at this time, the translation plate 2 will be driven to move up and down, and the first fixed gear 51 is fixedly connected to the support platform 1, and the transmission gear 53 meshing with the first fixed gear 51 will surround the first fixed gear 53. The gear 51 rotates, and after the transmission of several transmission gears 53, it will eventually drive the second fixed gear 52 to rotate together. Since the number of transmission gears 53 is 2N+1, it will make the second fixed gear 52 and the second fixed gear 52 rotate together. The rotation direction of the support arm 3 is opposite. Since the gear parameters are the same, the translation plate 2 will also rotate when it is driven up and down by the support arm 3 to ensure that it is always in a horizontal state.
