Problems solved by technology

[0003] In the design of hydraulic transmission, the operation of the airtight door is carried out through the combined use of the hand wheel and the hydraulic device. There are many operating steps, and the debugging and installation are cumbersome, requiring a lot of manpower and time.
[0004] In the design of motor transmission, there is no transmission box for separate adjustment, and it needs to be adjusted step by step after the installation of the personnel gate, which requires a lot of manpower and time; when the door is opened by a single hand wheel, only the near-end door can be operated, and the function is not perfect

Embodiment Construction

[0034] Such as Figure 1 to Figure 15 The transmission box for the personnel gate based on the sheave transmission shown is mainly composed of a box assembly 1, a door lock sheave assembly 2, a main drive shaft assembly 3, a door opening sheave assembly 4, a connecting arm assembly 5, and a balance valve opening assembly 6. Transmission gear assembly 7, balance interlock sheave assembly 8, interlock assembly 9, hand wheel shaft assembly 10 and other components.

[0035] The box assembly 1 is a welded frame structure, which is mainly composed of a support plate, a middle partition, a front panel, a side plate, a bottom plate, a top plate, and upper and lower side covers. Except that the front panel and the upper and lower side covers are connected by bolts, the rest All are welded to form a whole, and the bolt connection of the front panel is beneficial to the installation of the internal components of the box and the overall processing of the box. The upper and lower side cov...

Abstract

The invention discloses a personnel gate transmission case based on sheave transmission, which comprises a case body, a connecting arm, a balance valve opening component, a transmission gear component, an interlocking component and a hand wheel shaft and is characterized in that the personnel gate transmission case further comprises a gate lock sheave, a gate opening sheave, a balance interlocking sheave and a main drive shaft component. The main drive shaft is mounted in the case body; a single-arm driving arm, a double-arm driving arm of the gate lock sheave and the gate opening sheave, and a secondary transmission gear are assembled on the main drive shaft, are independent of one another axially, and have phase difference at a certain angle; the secondary gear is engaged with the transmission gear component; the single-arm driving arm can be freely connected with the balance interlocking sheave; and the double-arm driving arm can be freely connected with the gate lock sheave and the gate opening sheave respectively, drive the balance interlocking sheave, the gate lock sheave and the gate opening sheave to realize rotation and position through notches in the sheaves and locking arcs of the notches, drive the balance valve opening component to open a balance valve, drive the gate lock sheave to open a gate lock and drive the gate opening sheave to open a sealing gate.

Description

technical field [0001] Nuclear power plant containment system. Background technique [0002] The transmission box of the personnel gate is the key component of the transmission system of the personnel gate, which completes the functions of opening and closing the personnel gate. In the existing personnel gate design, the transmission system either adopts hydraulic transmission or electric motor transmission. [0003] In the design of hydraulic transmission, the operation of the airtight door is carried out through the combined use of the hand wheel and the hydraulic device. There are many operating steps, and the commissioning and installation are cumbersome, requiring a lot of manpower and time. [0004] In the design of motor transmission, there is no transmission box for separate adjustment, and it needs to be adjusted step by step after the installation of the personnel gate, which requires a lot of manpower and time; when the door is opened by a single hand wheel, only...
