Description

Jacking rotating mechanism Technical Field The utility model relates to the technical field of jacking devices, in particular to a jacking rotating mechanism. Background The jacking rotating mechanism is an important system component in the AGV, and mainly completes automatic conveying work of skip cars, material frames and the like, so that connection automation is realized. Common lifting and rotating mechanisms such as scissor fork type, ball screw lifting type and the like. The scissor type jacking rotating mechanism is low in efficiency and is easy to influence the cruising of the AGV vehicle-mounted battery. The ball screw lifting mechanism has the problems of small bearing capacity and the like and needs to be improved. Disclosure of utility model In order to solve at least one technical defect, the utility model provides the following technical scheme: The application discloses a jacking rotating mechanism which comprises a fixed plate, a supporting plate and a plurality of groups of screw rod lifting mechanisms, wherein the screw rod lifting mechanisms comprise screw rods and matched nuts, the nuts in the screw rod lifting mechanisms are connected with the supporting plate, a first gear, a second gear, a third gear and a driving mechanism are arranged on the fixed plate, the first gear and the third gears are meshed with the side of the second gear and are in rotary connection with the fixed plate, the screw rods in the screw rod lifting mechanisms are longitudinally arranged relative to the fixed plate and are connected with the third gear, a driving mechanism is transversely arranged on the fixed plate, and the driving mechanism is provided with a hyperboloid gear reducer, and the output end of the hyperboloid gear reducer is connected with the first gear to drive the hyperboloid gear reducer to rotate. In this scheme with actuating mechanism drive first gear rotation to first gear drive second gear rotates and makes the third gear rotate in step, and the lead screw rotates and makes the backup pad that links to each other with the nut go up and down in step, and whole mechanism occupies small, efficient, the bearing capacity is high, satisfies on-vehicle etc. demand. In the scheme, the hyperboloid gear reducer is in butt joint with a motor part in the driving mechanism, the driving mechanism can be transversely arranged on the fixed plate, the longitudinal size of the jacking rotating mechanism is further reduced, and the requirements of vehicle-mounted installation and the like are facilitated. Further, actuating mechanism includes brushless motor and hyperboloid gear reducer, brushless motor transversely sets up and brushless motor's output links to each other with hyperboloid gear reducer's input on the fixed plate, hyperboloid gear reducer's longitudinal direction's output links to each other with first gear, and brushless motor has higher efficiency and control accuracy is high to brushless motor is helpful improving the lifting accuracy as the power supply. Further, the material of first gear, second gear, third gear is made for steel or titanium steel, the external diameter of lead screw is 40mm, improves the material of gear in this scheme, uses thicker lead screw, helps further improving the load, satisfies the lift demand of bigger weight. Further, the supporting plate and the fixing plate are arranged in parallel. Further, the nut is arranged at the bottom surface of the supporting plate, so that the top surface of the supporting plate can be conveniently abutted against an object to be lifted.
