Linkage door opening and closing mechanism

Abstract

The invention relates to a linkage door opening and closing mechanism. The mechanism comprises an openable and closeable door, a rotating shaft part, a material carrier and a connecting rod part, wherein the openable and closeable door is installed through the rotating shaft part and can rotate around a rotating shaft of the rotating shaft part so that opening and closing of the openable and closeable door can be achieved; the connecting rod part comprises a connecting rod, and the two ends of the connecting rod are connected to the material carrier and the openable and closeable door correspondingly so that the opening and closing process of the openable and closeable door can be linked with the in-out process of the material carrier; and the two ends of the connecting rod are connected to the material carrier and the openable and closeable door through self-aligning roller bearings correspondingly so that self-aligning can be achieved under the condition that the rotating shaft part is bent under stress, and it is guaranteed that the openable and closeable door opens, closes and rotates smoothly and is closed tightly. The mechanism has the beneficial effects that door opening and closing actions and feeding or discharging of materials can be achieved through one set of driving device, the manufacturing cost is saved, and the fault occurrence rate of the mechanism is reduced. When the weight of the openable and closeable door is large, the openable and closeable door can still rotate smoothly and is closed more tightly even though the rotating shaft is bent under stress when the openable and closeable door rotates.

Description

technical field [0001] The invention belongs to the field of nuclear industry, and in particular relates to a linkage opening and closing mechanism. Background technique [0002] At present, when realizing the function of opening the door to send materials in or out, the action systems are often independent of each other, that is, a set of driving devices is provided for the door opening action, and a set of driving devices is provided for the carrier of material feeding or sending out. Adopting this kind of independent action system requires two sets of driving devices, which increases the manufacturing cost and has a high failure rate, which may cause safety problems in some occasions. However, the driving device of the material carrier fails and fails to send the material into the door. At this time, the material will be outside the measurement room for a long time. If the material contains strong radioactivity, there may be radiation safety problems, and it will also aff...

Problems solved by technology

When the weight of the switch door is large, due to the action of gravity, the switch door will cause flexible deformation to the rotating shaft when the switch door rotates, making the rotation of the switch door not smooth, and it is easy to wear, and the rigid rotating structure is easy to make the switch door After closing, it is easy to leave a gap (that is, the closure is not tight), and this gap will often increase the interference of the environment and the change of the position of the material for precise measurement, thus affecting the accuracy of the measurement
