Abstract
The utility model discloses an upright post rotating underpan for a digital radiography system, which comprises a rotary soleplate and a fixed soleplate and further comprises a turnplate bearing. The outer ring of the turnplate bearing is fixed on the fixed soleplate; and the rotary soleplate is fixed on the inner ring of the turnplate bearing. The upright post rotating underpan for the digital radiography system adopts one turnplate bearing to replace the existing combined structure of thrust ball bearings and annular ball bearings, thus simplifying the structure of the upright post rotating underpan, providing convenience for installing the upright post rotating underpan, reducing the spatial size of the upright post rotating underpan, and reducing using cost.
Description
Technical field
This utility model relates to the armarium technical field, is specifically related to a kind of digital irradiation photography system pillar rotary chassis.
Background technology
In present clinical diagnostic imaging, the irradiation image diagnosis occupies 50% proportion, and the irradiation image diagnosis has become the most conventional diagnostic means of current hospital.The X-ray machine that current irradiation image equipment is in traditional band film progressively is replaced by modern digitalization radiation image system, be DR (Digital Radiography, digitalization radiation shooting) system, the DR system is with its clear picture, transmission and convenient storage, image taking speed is fast, significantly reduces advantages such as the suffered radiological dose of patient, and is subjected to pursuing of market.
Suspension bulb suspension bracket, the all-electric multi-functional photography frame of column are equipped with the active checking bed, be realize that human body is upright, clinostatism satisfies from the head, the desirable DR system of each position film making of whole body such as breast, abdominal part and extremity.Product uses or operating process: suspension bulb emission X ray, and penetrate human body and form image, receive through detector, convert digital signal to, be transferred to computer and on display, generate inside of human body structure image, be used for patient's inspection, diagnosis.
As shown in Figure 1, the all-electric multi-functional photography frame of column is called for short column 12, its effect is the frames of DR detector 11, make DR detector 11 can be in the space level, vertically put, move up and down, around the rotation of column 12 centrages, so just can cooperate, the omnibearing photography inspection of patient with the suspention bulb.Pillar rotary chassis 13 bears whole total weight, and also because DR detector 11 is cantilevers to be installed, so it also will bear bigger moment of flexure stress, according to the functional requirement of column 12, the running accuracy of pillar rotary chassis 13 is higher.
As shown in Figure 2, the pillar rotary chassis 13 of prior art comprises rotation base plate 131 and fixed base plate 132 and is arranged on radial ball bearing 133, radial ball bearing 134 and the thrust ball bearing 135 that rotates between base plate 131 and the fixed base plate 132, its shortcoming is that the contact surface of the Internal and external cycle of bearing has strict tolerance grade and roughness requirement, the combinative structure of a few cover bearings requires just higher, install just more loaded down with trivial details, the manufacturing cost of part is higher, and the occupation space size is bigger besides.
The utility model content
The technical problems to be solved in the utility model provides a kind of digital irradiation photography system pillar rotary chassis, that the pillar rotary chassis that overcomes prior art is installed is loaded down with trivial details, the accuracy of manufacture require high, larger-size defective takes up room.
This utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of digital irradiation photography system pillar rotary chassis comprises rotation base plate and fixed base plate, also comprises turntable bearing, and the outer ring of described turntable bearing is fixed on the described fixed base plate, and described rotation base plate is fixed on the inner ring of described turntable bearing.
Described digital irradiation photography system pillar rotary chassis, the outer ring of wherein said turntable bearing is fixed on the described fixed base plate by screw or pin key.
Described digital irradiation photography system pillar rotary chassis, wherein said rotation base plate is fixed on the inner ring of described turntable bearing by screw or pin key.
Described digital irradiation photography system pillar rotary chassis is provided with the gear teeth on the outer ring of wherein said turntable bearing.
Described digital irradiation photography system pillar rotary chassis is provided with the gear teeth on the inner ring of wherein said turntable bearing.
Described digital irradiation photography system pillar rotary chassis, wherein said turntable bearing is made as roller bearing, ball bearing or ball-roller bearing.
Described digital irradiation photography system pillar rotary chassis, wherein said roller bearing is made as crossed roller bearing.
Described digital irradiation photography system pillar rotary chassis is provided with spacing holder between the cylindrical roller of wherein said crossed roller bearing.
The described cylindrical roller that described digital irradiation photography system pillar rotary chassis, wherein said spacing holder are separated is orthogonal.
The beneficial effects of the utility model are: this utility model digital irradiation photography system pillar rotary chassis is with a turntable bearing, substitute the combinative structure of a few cover bearings of existing thrust ball bearing and radial ball bearing, simplified the structure of pillar rotary chassis, made things convenient for the installation of pillar rotary chassis, dwindle the bulk of pillar rotary chassis, reduced use cost.
