Rotating mechanism for quick door opening device

Abstract

The invention discloses a rotating mechanism for a quick door opening device. The rotating mechanism is a rotating part (3) comprising a motor II (31), a rotating shaft (32), a support base (33) and a disk (34), wherein the output shaft of the motor II (31) is detachably connected with one end of the rotating shaft (32) for driving the rotating shaft (32), the rotating shaft (32) is arranged in the support base (33), the support base (33) is detachably connected with an end flange (51) of the quick door opening device, the disk (34) is detachably fixedly connected with the other end of the rotating shaft (32), and the disk (34) is fixedly connected with a connecting part. The rotating mechanism is capable of realizing rapid opening and closing of a large vertical quick-opening door , and is simple, safe, and reliable in operation.

Description

technical field [0001] The invention relates to a rotating mechanism for a quick door opening device. It relates to the technical field of piping systems. Background technique [0002] With the rapid development of my country's national economy, quick-opening devices have been widely promoted and applied in petrochemical, pharmaceutical, food hygiene, nuclear power and other light and heavy industries. The lifting and rotating mechanism is a key part to ensure the safe operation of the quick-opening device, and their safe operation is related to the safety of people's lives and property. There are many literature reports on the research and development of quick-opening blind plates at home and abroad, such as: a clamp-type quick-opening blind plate, which is equipped with radial ball bearings and thrust ball bearings at both ends of the opening and closing screw support mechanism. The auxiliary two-way bearing support mechanism reduces the operating force of the quick-open...

AI Technical Summary

Problems solved by technology

[0003] CN2918901Y discloses a lifting and rotating mechanism for a quick-opening device. Although the lifting and rotating of the quick-opening device can be realized, and the structure is simple, the lifting parts only have a simple screw and a tubular body, and the rotation is only a rotating shaft and a support. seat, can not achieve the purpose of quick opening

[0004] The structure of the existing technology cannot realize the self-lifting and rotation of the large vertical quick-opening door. Explosion-proof is required in places used in the petrochemical industry, and the height of large-scale vertical equipment is high, so a large-scale explosion-proof crane must be hired to lift the door of the quick-opening door device. After the equipment is lifted, it is transported from high altitude to the ground. After the equipment maintenance is completed, the door is hoisted to the high altitude with the help of a crane, and the door can only be put into a suitable position after manual adjustment. This increases maintenance costs, poses safety hazards, and loses the meaning of quick opening.
