An equipment gate transport device

Abstract

The invention discloses an equipment hatch transportation device, comprising a horizontal beam arranged on side stand columns of an equipment hatch, wherein the inner side of the horizontal beam is connected with a guide rail which is in matching connection with a slider below a support lug of the equipment hatch, a long cross beam is arranged between stand columns in front of the equipment hatch, two front inclined supports are arranged below the long cross beam, the long cross beam and the two front inclined supports constitute an inverted triangular structure, two side inclined supports are arranged between the side stand columns of the equipment hatch, and the two side inclined supports constitute an X-shaped structure. When the equipment hatch needs to be moved out from or in a hatch channel, the equipment hatch transportation device can be used to assist an annular hoist to guarantee the safety and stability in transporting the equipment hatch. Meanwhile, bolt structures can be adopted for all connections of the equipment hatch transportation device, so that the assembly and disassembly of the equipment hatch transportation device are facilitated, and the occupied space is reduced.

Description

technical field [0001] The invention relates to a transport trolley structure, in particular to an equipment gate transport device. 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 power plant.

AI Technical Summary

Problems solved by technology

[0003] During the construction and installation of the existing equipment gate of the nuclear power plant, when large equipment enters and exits the gate channel, there is interference, and the upper support bracket of the gate needs to be removed; when the interference size is too large, the equipment gate needs to be removed from the gate channel and stored separately
