Embodiment 1

[0030] like figure 1 As shown, a rotary opening and closing type door control device for a shielded door is used for the opening and closing operation of a rotary opening and closing type shielded door 6 with a hinge 8 structure. , guide chainring 2, motor 9, torque adjustment part 4 and drive gear 3;

[0031] The guide toothed disc 2 is provided with an annular tooth surface, and the annular tooth surface is one-half of the entire annular tooth surface, and the guide toothed disc 2 is fixed on the toothed disc frame 1;

[0032] The torque regulating part 4 includes a speed reducer, and the motor 9 is connected with the driving gear 3 through the torque regulating part 4;

[0033] The toothed plate frame 1 is used to fix the guide toothed plate 2 on the wall, and the axis of the circular tooth surface is collinear with the hinge shaft axis of the hinge 8; the motor 9 is fixed on the screen door 6, and the The gear teeth on the drive gear 3 and the annular tooth surface are e...

Embodiment 2

[0039] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to facilitate the disconnection of the drive gear 3 and the motor 9 in the case of power failure, when the shield door 6 is manually opened and closed, the resistance caused by the motor drive torque generation and transmission components to the shield door 6 is reduced. According to the technical solution, the torque regulating part 4 also includes an electromagnetic clutch, the electromagnetic clutch is in a combined state when the power is on, and the electromagnetic clutch is in a tripping state when the power is off, and the rotor of the motor 9 is connected to the reducer through the electromagnetic clutch The input end is connected, and the drive gear 3 is connected to the output end of the reducer.

[0040] In order to facilitate the disconnection of the driving gear 3 and the motor 9 in the case of power failure, another method to reduce the resistance caused ...

Embodiment 3

[0049] This embodiment provides a specific implementation plan: the largest structural component of the rotary opening and closing door control device is the guide toothed disc 2, and the side of the guide toothed disc 2 is provided with a semicircular tooth surface, with a diameter of 906 mm and a width of 80 mm. , the driving mechanism includes a motor 9, a reducer, an electromagnetic clutch and a driving gear 3, the total length is about 660mm, the overall size is small, and the total weight is nearly 150kg. The design considers the characteristics of lightness and compactness to the greatest extent: the main structure of the door control device The material is hot-rolled steel plate Q235B, the gear material is high-quality carbon structural steel No. 40 steel, the rack material, keys, pins, etc. are alloy structural steel 40Cr, the bolts and screws are 2Cr13, and the nut material is 1Cr13. Each part of the device adopts a detachable connection form, occupies less space duri...

Abstract

The invention discloses a rotating opening and closing type door control device for screen doors and discloses a design and an application of a rotating opening and closing type door control device capable of electrically opening and closing bearing-hinge type screen doors in open radiological laboratories or reactor supporting facilities. The door control device is a complete set of mechanical and electrical products, can electrically open and close the bearing-hinge type screen doors and also has manual opening and closing functions, a product with good universality, adaptability, high safety and high operability is finally formed through special structural design and component integration, and a very useful supporting product is provided for opening and closing of the screen doors in the open radiological laboratories or the reactor supporting facilities.

Description

technical field [0001] The invention relates to the technical field of an automatic opening and closing device for a shield door in an open radioactive laboratory or reactor supporting facilities, in particular to a rotary opening and closing gate control device for a shield door. Background technique [0002] In open radioactive laboratories or reactor supporting facilities, some process operations with strong gamma rays need to be carried out in completely shielded and protected spaces, and these spaces often require passages for staff and objects to enter and exit. Therefore, most of these Openings and doors are opened in the space. [0003] Because there are strong radioactive source items placed in these spaces, the doors set at the entrance and exit are different from ordinary isolation doors or hermetic doors, but shielded doors with ionizing radiation protection functions, and such doors generally adopt rotary opening and closing. formula structure. Because for str...
