The invention discloses a temporary storage device for an equipment gate. The device comprises a horizontal beam arranged on a stand column, one end of the horizontal beam is connected with an embedded bolt on the inner wall of a safety shell, the other end of the horizontal beam is connected with a transporter in a nuclear island, the outer side of the horizontal beam is connected with a pull rod, the inner side of the horizontal beam is connected with a guide rail, the guide rail is arranged on the stand column, a sliding block below a support lug of the equipment gate slides and is stored on the guide rail, and a locking check block used for preventing the gate from sliding is also arranged on the horizontal beam. Due to the adoption of the device, when the equipment gate is constructed, or the equipment gate moves out from a gate channel, the linear movement of the gate on the guide rail is realized by the matching between the guide rail and the sliding block of the gate, the vertical storage is provided for the gate, the storage space of the gate is saved, the equipment gate can be stored safely and stably, and the equipment gate is convenient to detach.
Description
technical field [0001] The invention belongs to a support bracket structure, and in particular relates to a temporary storage device for an equipment gate. Background technique [0002] The containment is the last barrier to prevent the leakage of radioactive materials, and its airtightness and safety play a vital role in reducing the impact of nuclear accidents on the public and the environment. The equipment gate is a part of the pressure boundary of the containment, and is an important mechanical device of the nuclear island. It undertakes the important task of maintaining the sealing of the containment, and is an integral part of the third safety barrier of the nuclear power plant. The equipment gate is installed on the reactor containment, which not only has the airtightness and safety required by the containment, but also serves as the access channel for large equipment in the reactor building during the construction, installation and refueling period of the nuclear po...
