Abstract
The utility model relates to a hinge for a nuclear power biological shield door, and belongs to the technical field of special nuclear power equipment. The hinge comprises a door-frame hinge base plate and a door-leaf hinge base plate, wherein the door-frame hinge base plate is fixedly connected with a door frame (or a door opening); the door-leaf hinge base plate is fixedly connected with a door leaf; the door-frame hinge base plate is fixedly connected and vertical to a door-frame hinge plate; the door-leaf hinge base plate is fixedly connected and vertical to a door-leaf hinge plate; the door-leaf hinge plate extends to a position where the door-leaf hinge plate is staggered with the door-frame hinge plate in the direction of the door-frame hinge plate; and the staggered part of the door-leaf hinge plate and the door-frame hinge plate is hinged through a hinge pin. The utility model has the advantages of simple structure and strong carrying capacity, is very suitable for nuclear power biological shield doors, and facilitates the installation and the further maintenance.
Description
Technical field
The utility model relates to a kind of hinge, and especially a kind of nuclear power biological shielding door hinge belongs to the extraordinary facility technology of nuclear power field.
Background technology
Understand according to the applicant, in the domestic in the past construction of nuclear power station engineering, because ancillary facility is immature, the hinge of nuclear power station biological shielding door is difficult to satisfy instructions for use, and maintenance and maintenance after putting into effect to nuclear power station bring a lot of difficulties.
Summary of the invention
The purpose of this utility model is: according to the technical characterictic of nuclear power biological shielding door, propose a kind of nuclear power biological shielding door hinge that can satisfy construction of nuclear power station needs, thereby offer convenience for the construction of nuclear power station and maintaining in the future.
In order to reach above purpose, nuclear power biological shielding door hinge of the present utility model contains the door leaf hinge base plate that is useful on the doorframe hinge base plate that is connected with doorframe (or door opening) and is used for being connected with door leaf; The doorframe flap that described doorframe hinge base plate is connected vertical with it, the door leaf flap that described door leaf hinge base plate is connected vertical with it; Described door leaf flap extends to intervening portion with it towards doorframe flap direction; Described door leaf flap and doorframe flap staggered place are hinged by bearing pin.
The utility model further improves: the upper end of described bearing pin has the axial limiting boss, and the cross section of described boss is circle and lacks shape; The position that described door leaf flap corresponding circle lacks has the axle bumper piece.Like this, when hinge axis is installed, can realize the circumferentially spacing of axle and door leaf flap easily.
Be understood that the utlity model has simple in structurely, the advantage that supporting capacity is strong very is suitable for nuclear power biological shielding door, and install and maintaining in the future all very convenient.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
Embodiment one
The nuclear power biological shielding door hinge of present embodiment contains and is useful on the doorframe hinge base plate 2 that is connected with doorframe (or door opening), is used for the door leaf hinge base plate 1 that is connected with door leaf as shown in Figure 1.The doorframe flap 8 that 2 welding of doorframe hinge base plate are connected vertical with it, the door leaf flap 3 that door leaf hinge base plate 1 is connected vertical with it.Door leaf flap 3 extends to intervening portion with it towards doorframe flap 8 directions.Door leaf flap 3 and doorframe flap 8 staggered places are hinged by bearing pin 4.Because in fact, bearing pin 4 constitutes revolute pair by bearing 6 and doorframe flap 8, therefore relatively rotates very flexible.The upper end of this bearing pin 4 has axial limiting boss 4-1.Lower end plug-in mounting limit shaft pin 7, thus axial limiting formed, avoid axial float.The cross section of positive stop lug boss 4-1 is circle and lacks shape, and the position that door leaf flap 3 corresponding circles lack is welded with axle bumper piece 5, and the realization axle is circumferentially spacing with the door leaf flap.
Facts have proved, adopt the used in nuclear power station biological shielding door hinge of present embodiment can guarantee the installation quality of degree of protection biological shielding door and safe in utilization, satisfy the quality requirement of the construction of nuclear power station.Whole hinge means is rational in infrastructure simple, gives to install and use with maintenance and brings many convenience.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
