Embodiment 1

[0039] Such as Figure 1 to Figure 4 As shown, a kind of shielding and airtight door structure in this embodiment is arranged in the entrance and exit channel of the factory building or workshop that requires shielding and sealing in the nuclear industry, and mainly realizes the shielding and sealing function. The working state of the airtight door is usually a closed state, and only needs to be opened When it is opened, its structure specifically includes an electric push rod 3, a door panel 6, an upper guide rail 8, a lower guide rail 1, an opening travel switch 2 and a closing travel switch 5; wherein, the electric push rod 3 is a method that converts the rotational motion of the motor into The linear reciprocating motion of the push rod is an electric drive device. The electric push rod 3 has a motor and a telescopic push rod 18. One end of the electric push rod 3 is provided with a motor and is fixed on the wall 16 through a bolt connection. One end of the rod 18 is fixed...

Embodiment 2

[0042] A screened airtight door structure in this embodiment includes all the technical features in Embodiment 1, in addition, such as figure 1 , figure 2 and Figure 4 Shown, also comprise a plurality of conical rollers 9, a plurality of conical rollers 9 are all rotatably connected to the upper end edge of the door panel 6, the rotating shafts of a plurality of conical rollers 9 all extend along the vertical direction of the door panel 6, in the upper guide rail 8 A strip-shaped groove is provided, and a plurality of tapered rollers 9 are arranged in the strip-shaped groove and are rollingly connected with the upper guide rail 8, wherein the shape of the tapered rollers 9 is conical, and the smaller end is set upwards. The cross-sectional shape of the elongated groove provided on the upper guide rail 8 is a trapezoid with a small upper part and a larger lower part. The tapered roller 9 rolls on the elongated groove. This structure runs smoothly and reliably, and has a long...

Embodiment 3

[0047] Such as Figure 1 to Figure 4 As shown, a shielded airtight door structure in this embodiment includes all the technical features in Embodiment 2. In addition, it also includes a first bumper 13, and the door panel 6 is close to the vertical edge of the travel switch 2. A first bumper 13 is provided, and the first bumper 13 is arranged facing the opening travel switch 2. The first bumper 13 translates along with the door panel 6. When the door panel 6 moves to the fully open position, the first bumper 13 hits Turn on the travel switch 2, and transmit the signal to control the electric push rod 3 to stop running. For example, the travel switch 2 is opened to two up and down, and the door panel 6 is opened and put in place by contact with the first bumper 13 respectively; the second bumper is also included. 14. A second touch block 14 is arranged on the vertical edge of the door panel 6 close to the closed travel switch 5, and the second bump block 14 is arranged facing t...

Abstract

The invention discloses a shielded and sealed door structure. The shielded and sealed door structure is arranged in a access passage of a workshop or a factory for shielding and sealing required by the nuclear industry, the end, provided with a motor, of an electric push rod is fixed to a wall, the end, provided with a telescopic push rod, of the electric push rod is fixed to a door plate, and theelectric push rod is used for driving the reciprocating horizontal moving motion of the door plate; an upper guide rail is connected with the upper end edge of the door plate in a rolling mode, a lower guide rail is slidably connected with the lower end edge of the door plate, the upper guide rail and the lower guide rail are fixed to the wall body, an opening travel switch is arranged on the wall body at the limiting position where the door plate is completely opened, and a closed travel switch is arranged on the wall body at the limiting position where the door plate is completely closed; and when the door plate is completely closed, the door plate is connected with walls of the periphery of the access passage through an elastic sealing part in a sealing mode. The shielded and sealed door structure aims to solve the problem that a sealing door in the prior art has the heavy weight and is not prone to opening and closing manually, and has the technical effects that the automatic opening and closing of the sealing door is achieved, the workload of the manual operation is reduced, and the shielding and sealing effect is good.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of equipment with shielding functions in the nuclear industry, specifically to a shielded airtight door structure used for access to a factory building or workshop in a radiation environment, and to a control method for the shielded airtight door structure. Background technique [0002] In the manufacturing, processing and processing industry of nuclear materials, radiation factors must be considered to meet the requirements for worker protection and space environment. The radiation environment generally realizes the shielding function through the walls of workshops or workshops, but in order to meet the requirements of personnel entering and exiting workshops or workshops Cargo transportation requires that a sealed door with shielding function must be installed, and such a sealed door must have a certain thickness to shield radiation, which leads to the heavy weight of the sealed door a...
