Abstract

The invention provides a door panel supporting and power buffering device. The device comprises a support frame (2), wherein a body of the support frame (2) is connected with a door panel through a spherical support structural member (5), both ends of the support frame (2) are respectively connected with an external structure of the door panel through an upper bearing hinge body (3) and a lower bearing hinge body (4); the spherical support structural member (5) comprises a connecting shaft (51) and a spherical bearing (52), and the spherical bearing (52) is arranged in a groove (11) in the door panel; the connecting shaft (51) penetrates through the body of the support frame (2) to be connected with the spherical bearing(52). According to the supporting and power buffering device disclosed by the invention, for each operation of opening a door, and in a certain state, the load of the door panel can be supported and the door panel can be driven to move, at the same time, the door is opened and closed, the device has the function of buffering, so that resilient displacement is reduced, and the safety and the stability of the door panel during operating can be ensured.

Description

technical field [0001] The invention belongs to the field of door panel design, and in particular relates to a door panel support and power buffer device, which is widely used on the door panels of the inner and outer doors of personnel gates to support, power buffer and evenly distribute the pre-tightening force of the personnel gate door panels role. Background technique [0002] The personnel gate is widely used in each nuclear power unit, and its main function is to allow personnel and small equipment to pass through when the reactor is running or thermally shut down, without damaging the sealing function of the containment. As a penetrating part of the reactor containment and a component of the third safety barrier, it undertakes the important task of maintaining the containment sealing and integrity. The personnel gate is frequently used, and every time it is opened or closed, the door panel needs to move with the transmission mechanism, so it is necessary to ensure i...
