Preferably, two screw rods 522 and two transmission shafts 521 can be adopted, and the lower end of each vertical screw rod 522 is in mesh transmission with one end of each transmission shaft 521 close to the screw rod 522 through a bevel gear pair. In addition, two vertical lead screws 522 are respectively and symmetrically arranged at two ends of the bracket 2, and the two lead screws 522 are limited by two lead screw nuts 6 fixed on the bracket 2, and meanwhile, the supporting capacity of the bracket 2 is also improved.

In some embodiments, referring to fig. 1, 4 and 7, a plurality of transmission shafts 521 are coaxially disposed at both sides of the driving member 52, and the plurality of transmission shafts 521 are synchronously linked. Therefore, synchronous transmission of the transmission shafts 521 can be ensured, and stability of the support 2 during lifting is further realized.

Here, the driving member 52 may also be a dual output shaft motor, for example, when there are two transmission shafts 521, when a dual output shaft motor is used, one transmission shaft 521 is fastened to each of the output shafts on both sides of the motor, so that the two transmission shafts 521 can rotate synchronously. If a single-output-shaft motor is adopted, two single-output-shaft motors are needed to be matched for use when the number of the transmission shafts 521 is two, so that the transmission efficiency is high and the structure is compact compared with the single-output-shaft motor.

In some embodiments, referring to fig. 2 and 4, the radiation detector moving device includes a control handle electrically coupled with the driving member 52 for controlling the driving member 52 to perform a corresponding response action. Here, the electrical coupling may be a wireless or wired connection, so that the operator can remotely control the operation of the drive member 52 via the control handle. The response operation may specifically refer to start/stop, acceleration, forward/reverse rotation of the output shaft of the driver 52, and the like of the driver 52.

In some embodiments, referring to fig. 2 and 4, the bracket 2 is provided with at least two fixing plates 9, at least two fixing plates 9 are respectively located at two opposite sides of the radiation detector 7, and at least a portion of the fixing plate 4 abuts against an outer wall of the radiation detector 7 for clamping the radiation detector 7 between the fixing plates 4. The arrangement of the at least two fixing plates 4 can realize that the radiation detector 7 is stably limited on the bracket 2 so as to prevent the radiation detector 7 from falling off in the three-dimensional direction movement adjusting process.

The fixing plate 9 is not limited in structural form, and preferably, referring to fig. 4, the fixing plate 9 is made of angle steel, which is low in cost and high in applicability, and specifically, the fixing plate 9 is fastened to the upper surface of the support plate 21 of the bracket 2 by a fastener, which may be a screw connection, a welding connection, or the like, and is not limited herein.

In some embodiments, referring to fig. 1 and 4, the radiation detector moving device further includes a plurality of rollers 8, and the plurality of rollers 8 are fixedly installed below the base 1. Therefore, the arrangement of the plurality of rollers 8 can conveniently realize the movement of the whole ray detector moving device in the horizontal direction. And the lifting motion of the ray detector 7 in the vertical direction is combined, so that the ray detector 7 realizes the moving adjustment in the whole three-dimensional direction, and the coincidence of the center of a detector flat plate and the center of a ray source can be realized through the three-dimensional moving adjustment.

It should be noted that the specific number of rollers 8 is not limited herein, and preferably, the number of rollers 8 is four, so that the base 1 is better supported than the design with less than four rollers 8, and the cost is saved compared to the design with more than four rollers 8. In addition, a plurality of gyro wheels 8 all adopt the universal wheel that has self-locking function, so, when convenient the removal, still have the positioning action, and then increased ray detector mobile device's suitability.

The above-mentioned serial numbers of the embodiments of the present application are merely for description and do not represent the merits of the embodiments. The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application, or which are directly or indirectly applied to other related technical fields, are included in the scope of the present application.
