Side transmission case for personnel airlock

Abstract

The invention discloses a side transmission case for a personnel airlock, which can be mounted at each of the inner side and the outer side of a cabin panel of the personnel airlock. The side transmission case structurally comprises a case body, wherein the case body is provided with a bearing block and hand wheels, the hand wheels include an upper hand wheel and a lower hand wheel which are used for operating a near-end sealing door and a far-end sealing door, the bearing block is used for supporting a straight-tooth driving gear system and an incomplete-gear system, and an incomplete gear III and a straight-tooth driving main gear are mounted on the same gear shaft. When the hand wheels are operated, the driving gear system can drive a connecting rod I and the incomplete gear to move, so as to drive a pressure balance valve, a locking device and a rack connected with a bevel gear of a middle transmission case to move to finally operate the near-end sealing door and / or the far-end sealing door. The side transmission case has the characteristics of small operating torque, cooperation of an incomplete gear structure and an interlocking device and arrangement of a boss-groove positioning device and the like, so that the side transmission case can be generally and separately adjusted and is very convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a containment shell system of a nuclear power plant, which belongs to the passage equipment for personnel in the containment shell. Background technique [0002] The transmission boxes on both sides of the personnel gate are a key part of the transmission system of the personnel gate. They are installed on both sides of the personnel gate cabin panel inside and outside, and the structure is basically the same. And form a transmission system with other shafts, gears, couplings, and middle transmission boxes. The transmission system of the personnel gate is the basis for completing the functional operation of the personnel gate. In the existing personnel gate design, the transmission system has two modes of hydraulic transmission and electric motor transmission. [0003] In the design of hydraulic transmission, the hydraulic device is used to press the sealing door, and it needs to cooperate with the hand wheel to operate the s...

AI Technical Summary

Problems solved by technology

[0003] In the design of hydraulic transmission, the hydraulic device is used to press the sealing door, and it needs to cooperate with the hand wheel to operate the sealing door. The operating hand wheel is set on the sealing door, and each component in the system is installed on the personnel cylinder and the sealing door , the commissioning and installation are relatively cumbersome, and the overall gradual commissioning after the installation of the personnel gate is required, which requires a lot of manpower and time, and there are many actual operation steps, which require the use of handwheel and hydraulic pressure

[0004] In the design of motor transmission, the transmission components are all installed on the cylinder body of the personnel gate and the airtight door, and there is no transmission box that can be adjusted separately. It needs to be debugged gradually after the installation of the personnel gate, which requires more manpower and time; the handwheel is used alone When opening the door, only the near-end door can be operated, and dozens of operations are required to complete the operation of the opposite door, which is time-consuming and laborious
