A kind of metallic substance cryogenic freezing is handled the opening device of chamber door, comprise the electric motor and the speed reduction unit that have braking devices, chamber door, two sides about chamber door, two pins are installed in each side, bearing is housed on the pin, in the casing doorframe outside one framework is arranged, vertically offer rectangular stopper slot on the framework corresponding to pin, offer two prongs under oblique towards casing on the stopper slot, the spacing of two prongs is corresponding with two pin spacings on the chamber door, bearing on the chamber door two side pins places in the stopper slot on the framework, the unlatching of chamber door is limited by prong and stopper slot with the motion track of closure, the lifting of chamber door is by chain type metal strip or rack drives, motor drive chain type metal strip or tooth bar.
Above-mentioned metallic substance cryogenic freezing is handled the opening device of chamber door, and the sealed strip of described chamber door is installed in the groove of casing doorframe or chamber door, in 50 millimeters near the bottom of the other or sealed strip groove of sealed strip, electric heater is installed.
Metallic substance cryogenic freezing of the present invention is handled chamber door and is adopted vertical opening/shutting mode, chamber door is under the chain type metal strip or rack drives that are driven by the speed reduction unit that has braking devices, motion track by stopper slot control chamber door, carry out VTOL, and chamber door and casing doorframe keep strict seal, prevent that Cryogenic air leaks in the casing, the chamber door of VTOL is convenient to deliver the dolly turnover casing of workpiece, and operation and safety in production are brought benefit.
Description of drawings
Fig. 1 is the opening device structural representation that metallic substance cryogenic freezing of the present invention is handled chamber door, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the structural representation of casing doorframe stopper slot.Fig. 4 is the chamber door sealed structural representation.
Among the figure: 1 electric motor and speed reduction unit, 2 chain type metal strips (or tooth bar), 3 frameworks, 4 casing doorframes, 5 chamber doors, 6 pins, 7 stopper slots, 8 prongs, 9 inner bags, 10 thermal insulation layers, 11 shells, 12 sealed strips, 13 electric heaters.
Embodiment
Referring to Fig. 1, Fig. 2, metallic substance cryogenic freezing processing tank is by the casing part, refrigeration plant, several most of compositions such as electric apparatus control apparatus.The chest portion branch comprises shell 11, thermal insulation layer 10, and inner bag 9.Chamber door 5 is perpendicular to surface-mounted, two sides about chamber door 5, two pins 6 are installed in each side, on the pin 6 bearing is housed, in casing doorframe 4 outsides one framework 3 is arranged, vertically offer rectangular stopper slot 7 on the framework 3 corresponding to pin, offer two prongs 8 under oblique towards casing on the stopper slot 7, the spacing of two prongs 8 is corresponding with two pin 6 spacings on the chamber door 5, bearing on the chamber door 5 two side pins 6 places in the stopper slot 7 on the framework 3, and it is light to adopt bearing that chamber door 5 is moved.The unlatching of chamber door 5 is limited by prong 8 and stopper slot 7 with the motion track of closure, and the lifting of chamber door 5 drives by chain type metal strip or tooth bar 2, and electric motor 1 drives chain type metal strip or tooth bar 2, and electric motor and speed reduction unit 1 are installed in the top of framework 3.
