Abstract
The invention discloses a hinge device of a protective door, comprising a fixed plate, a bearing fixed on the fixed plate, a main shaft sleeved in the bearing and a hinge arranged on the main shaft, wherein a bearing bush is arranged at the lower end of the bearing; an oil filling hole is arranged on the bearing bush; and a group of screw holes for connecting is arranged on the hinge. The hinge device of the protective door has simple structure and can effectively regulate gravity centre structure of the hinge so as to cause the hinge to suffer from stress uniformly.
Description
Technical field
The present invention relates to the hinge means of a kind of protector of nuclear power station, particularly protective door.
Background technology
Existing protective door hinge means complex structure, physical life is short, has influenced the switch and the regular maintenance of protective door greatly, and manufacturing cost is higher, so, to produce a kind of simple in structurely, the linked set of good practical effect is a urgent problem.
Summary of the invention
Goal of the invention: the deficiency to prior art the invention discloses a kind of hinge means that can effectively adjust the protective door of center of gravity structure.
Technical scheme: the invention discloses a kind of hinge means of protective door, comprise fixed head, be fixed on the bearing on the fixed head, be enclosed within the main shaft in the bearing and be arranged on the hinge on the main shaft; Said bearing lower end is provided with bearing shell, and bearing shell is provided with oil filler point; Said hinge is provided with one group of connection and uses screw hole.
Wherein, be provided with external screw thread around the said main shaft, bearing is a single direction thrust ball bearing, the bearing inboard be provided with main shaft on the internal thread that matches of external screw thread, can adjust the height of the hinge that connects main shaft, the hinge that is is evenly stressed.
Wherein, said connection uses screw hole to be ellipse, convenient concentricity of regulating hinge.
Wherein, said one group of connection is at least 4 with screw hole, and the quantity of rational connection with screw hole can be set according to the big or small weight of protective door.
Beneficial effect: the hinge means of protective door disclosed by the invention, simple in structure, can effectively adjust the center of gravity structure of hinge, the hinge that is is evenly stressed.
Description of drawings
Accompanying drawing 1 is the structural representation of hinge.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
The invention discloses a kind of hinge means of protective door, comprise fixed head 1, be fixed on the bearing 2 on the fixed head 1, be enclosed within the main shaft 3 in the bearing 2 and be arranged on the hinge 4 on the main shaft 3; Said bearing 2 lower ends are provided with bearing shell 5, and bearing shell 5 is provided with oil filler point 7; Said hinge 4 is provided with one group and connects with screw hole 5.
Wherein, be provided with external screw thread around the said main shaft, bearing is a single direction thrust ball bearing, the bearing inboard be provided with main shaft on the internal thread that matches of external screw thread, can adjust the height of the hinge that connects main shaft, the hinge that is is evenly stressed.
Wherein, said connection uses screw hole to be ellipse, convenient concentricity of regulating hinge.
Wherein, said one group of connection is at least 4 with screw hole, and the quantity of rational connection with screw hole can be set according to the big or small weight of protective door.
The hinge means of protective door disclosed by the invention, simple in structure, can effectively adjust the center of gravity structure of hinge, the hinge that is is evenly stressed.
The invention provides a kind of thinking and method of hinge means of protective door, realize that specifically the method for this technical scheme and approach are a lot, the above only is a preferred implementation of the present invention; Should be understood that; For those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching; These improvement and retouching also should be regarded as protection scope of the present invention, and all available prior art of each ingredient not clear and definite in the present embodiment realizes.
