[0003] For large-scale equipment, the tank door is relatively heavy, and manual door opening requires more manual power; both pneumatic door opening and hydraulic door opening require a special power source, which is very inconvenient and increases costs; When the door is opened, the transmission of the worm gear is in surface contact, and the friction force is large, which makes the parts easy to wear, the transmission efficiency is low, and it cannot meet the production demand.

Abstract
The invention provides a tank door opening device based on a planetary roller screw, including a servo motor, a planetary gear reducer, a coupling, a planetary roller screw, a long connector and a tank door assembly, and a planetary roller screw The rod includes a screw shaft, two roller cages, a plurality of rollers and nuts, the rollers are threadedly engaged with the screw shaft and the nut at the same time, the tank door assembly includes a tank door, a connecting rod and a first support, the tank door Cooperate with the top of the tank body, the long connecting piece is fixedly connected with the nut, and is hinged with the first support through a movable hinge near the free end of the connecting rod; the servo motor drives the planetary gear reducer to rotate, and the planetary gear reducer drives the wire through the coupling When the rod shaft rotates, the screw shaft drives the rollers to move, and the rollers drive the nuts to move down or up, thereby driving the tank door assembly to move, opening or closing the tank door. The invention has reasonable structure, flexible opening and closing, good sealing performance, simple and labor-saving operation, ensures the reliability of opening and closing of the tank door, improves work efficiency and reduces cost.
Description
technical field [0001] The invention belongs to the technical field of valve automatic control, in particular to a tank door opening device based on a planetary roller screw. Background technique [0002] Existing pressure vessels such as autoclave, autoclave, autoclave and other equipment need to have good sealing performance. The tank door is generally connected to the tank body by hinges or a boom link device connected to the upper part of the tank body. The disadvantage is that when the diameter of the equipment is large, the weight of the tank door is very large, and it is laborious to open and close the tank door. Some equipment with a larger diameter will undoubtedly require greater force when turning the tank door, making it difficult to open and close the tank door , and even affect the sealing performance of the tank door, and it is difficult to correct the shape, which is quite troublesome for how to quickly open the tank door of the pressure vessel. There are fo...
