Sealing crane gate

Abstract

The invention discloses a sealing crane gate which provides dynamic air seal by arranging a ventilation system connected into a hot chamber where an air inlet filter is located when the air inlet filter is opened, and static sealing separation of a gate chamber and the hot chamber where the gate chamber is located is achieved through a gate chamber sealing ring and a door plate annular sealing ring. The power of the gate lifting servo driving mechanism is reduced by adopting a balancing weight; the counterweight and the door plate unloading mechanism which are arranged on the two sides are adopted, so that the convenience and the safety of the gate opening operation process are enhanced; through the structure of the gate lifting driving module, installation, detection and maintenance are convenient; the counterweight block is made of lead, so that the height of the steel structure gate chamber is obviously reduced; door plate unloading mechanisms arranged on the two sides are adopted, so that chain bearing only occurs in the lifting process, and the chain is basically in the no-load state at other time; gamma shielding continuity is realized through combination of the upper and lower parts of the door plate and the steps. The gate is reasonable in structural design, convenient to install and maintain and suitable for being popularized and used in the technical field of special equipment with shielding and sealing requirements.

Description

Technical field [0001] The present invention relates to a sealing crane gate, belonging to the rear end processing of nuclear fuel cycles, and the technical field of disposal facilities. Background technique [0002] The lack of fuel treatment facilities, isotope production treatment facilities, radiochemical laboratories are typically composed of a thermal chamber of multiple adjacent different process functions, and these thermal chambers are separated by different process functions, and their ambient atmosphere, ventilation or Internal pressure control requirements are not the same. According to the existing technology route, the entire heat chamber wire usually uses the following remote operating equipment: such as a remote control crane, bridge power robot, electro-operative or remote crane and other two equipment design integrated equipment. Remote cranes and other remote operating equipment need to pass through the operating procedures to enter each heat chamber on the hea...

AI Technical Summary

Problems solved by technology

The internal space of the gate chamber and the internal space of the hot chamber are not sealed, and there are many inconveniences in the installation and maintenance of the equipment.

In addition, with the increasing processing capacity and shielding requirements of the above-mentioned facilities, the door panel size and weight of the crane gates of the newly-built facilities have increased significantly
