As shown in fig. 1, the technetium bucket transfer apparatus includes a technetium bucket supporting unit including a technetium bucket holder for supporting a technetium bucket 3, and a technetium bucket transfer unit including a transfer part grasping and transferring the technetium bucket, and a power-assisted part which is power-assisted to be lifted when the technetium bucket 3 is lifted and plays a role of slowly descending when the technetium bucket 3 is lowered. The transfer component comprises a grabbing component, a supporting arm component and a transfer sliding rail component, one end of the supporting arm component is connected with the grabbing component, the other end of the supporting arm component is connected to the transfer sliding rail component in a sliding mode, and the power assisting component is connected to the supporting arm component through a rotating shaft.

In this embodiment, the grasping assembly includes a first arm and a second arm 12 which are parallel to each other and freely drooping, the top ends of the first and second arms 12 are rotatably connected to the free ends of the first and second support arms 11 which are parallel to each other in the support arm assembly, and the lower ends of the first and second arms 12 have a hook structure which can be hooked on the protrusions 31 on both sides of the upper end of the technetium bucket 3, and when the free ends of the support arms are moved toward the operator, the technetium bucket 3 is lifted by the first and second arms 12 and taken out of the technetium bucket holder by being pulled by the hooks.

The support arm assembly comprises a first support arm and a second support arm 11 which are parallel to each other, the transfer slide rail assembly comprises a first transfer slide rail and a second transfer slide rail 15 which are parallel to each other, and the upper ends of the first support arm 11 and the second support arm 11 are respectively connected with the top ends of the first arm 12 and the second arm 12 in a rotating mode, so that the first arm 12 and the second arm 12 can rotate freely relative to the first support arm 11 and the second support arm 11. The lower ends of the first and second support arms 11 are slidably connected to the first and second transfer slide rails 15, respectively, and move along the length direction of the first and second transfer slide rails 15. In order to ensure that the distance between the two support arms 11 does not change with the lifting and lowering processes during the technetium barrel 3 transferring process, so that the transferring process is more stable and reliable, in the present embodiment, it is preferable to provide a strong connecting member 13 connected between the first and second support arms 11 on the upper end side of the two support arms 11 away from the transferring slide rail assembly, and the use of the strong connecting member 13 with higher rigidity ensures that the distance between the two support arms 11 does not change, so that the rotating and moving processes of the two support arms 11 are smoother and more stable.

As a key component for reducing the difficulty of transferring the technetium bucket 3 by the operator, the boosting component in this embodiment includes a first boosting rod and a second boosting rod 14 respectively located at the outer sides of the first supporting arm and the second supporting arm 11, the first boosting rod 14 and the second boosting rod 14 have fixing bases 141 fixed at the outer sides of the first transferring slide rail 15 and the second transferring slide rail 15, and as the fixing ends of the first boosting rod 14 and the second boosting rod 14, the fixing ends of the first boosting rod 14 and the second boosting rod 14 are fixed in the moving process of the technetium bucket 3. First, second helping hand pole 14 still along first, second support arm 11 outside gliding pivot 142, as first, second helping hand pole 14 rotation end, pivot 142 fixed connection in first support arm and second support arm outside and make first, second helping hand pole 14 respectively with first, second support arm 11 interval setting to avoid colliding each other between helping hand pole 14 and the support arm 11 in the rotation process and influencing technetium bucket and shift's smoothness nature. Wherein the fixed position of the rotating shaft is best to be capable of boosting the technetium barrel to the highest position. As a preferred mode of the structure of the power-assisted rod 14, the first and second power-assisted rods are hydraulic rods, and the maximum length of the power-assisted rods in the stretching state is not less than the maximum vertical distance for lifting the technetium bucket, so as to further ensure that the power-assisted rods 14 can play a role in boosting and lifting the technetium bucket 3.

In addition, according to the requirement of the layout of the internal components of the whole automatic dispensing system, the position of the technetium bucket can be flexibly adjusted, and the technetium bucket supporting unit can move along the supporting slide rail 22 along the horizontal direction in the embodiment, so that the placing position of the technetium bucket can be flexibly changed, the technetium bucket transferring unit can be better matched to find the optimal position for lifting and placing the technetium bucket, and the whole operation process is more flexible and the operable space is larger. Because the radioactive emphasis of the technetium bucket stock solution is large, in order to further reduce the radiation of the technetium bucket 3 to other areas of the environment and the liquid medicine preparation system, the lead plate 21 positioned at the periphery of the technetium bucket is arranged in the technetium bucket supporting unit in the embodiment, so that the radiation of the technetium bucket is reduced to the minimum, and the protection effect on operators is improved.

The operation of the technetium bucket transfer device of the present invention will be described in detail based on the structural designation shown in fig. 1 and the transfer process schematic diagrams shown in fig. 2A-2C.

As shown in fig. 2A, when the technetium bucket 3 is positioned in the technetium bucket holder, the operator pushes the upper ends of the first and second support arms 11 close to the technetium bucket, suspends the first and second arms 12 above the technetium bucket, and operates to hook the hooks at the lower ends of the first and second arms 12 on the projections 31 on both sides of the upper end of the technetium bucket 3. At this time, the first and second assist levers 14 of the assist member are compressed relatively, and the lower ends of the first and second support arms 11 slide to the side close to the operator along the first and second transfer rails 15.

As shown in fig. 2B, when the operator gradually pulls the upper ends of the first and second support arms 11 outward, the first and second power-assisted levers 14 (e.g., hydraulic levers) can push the upper ends of the first and second support arms 11 to move upward continuously based on their own properties, and finally the technetium bucket is removed from the technetium bucket holder. In this process, the first and second assist levers 14 are continuously extended, and the lower ends of the first and second support arms 11 are moved to the side away from the operator along the first and second transfer rails 15.

As shown in fig. 2C, when the operator continues to pull the upper ends of the first and second support arms 11 outward, the technetium bucket is lifted to the highest point and then gradually lowered, and under the slow lowering action of the first and second power-assisted rods 14, the technetium bucket does not fall too fast to cause an excessive load on the operator, and finally falls to a height convenient for the operator to extract, the operator takes the technetium bucket off from the hook at the lower end of the first and second arms 12, thereby realizing the process of unloading the technetium bucket. In this process, the first and second booster bars 14 are continuously compressed, and the lower ends of the first and second support arms 11 continue to move to the side away from the operator along the first and second transfer rails 15.

The process of loading the technetium bucket is opposite to the above process of unloading the technetium bucket, and the operator only needs to place the technetium bucket on the hooks at the lower ends of the first and second arms 12, and then push the upper ends of the first and second support arms 11, and the technetium bucket is gradually lifted, moved, lowered and loaded in the technetium bucket holder under the driving of the first and second support arms 11 and the assistance of the first and second boost levers 14, so that the loading of the technetium bucket can be realized.

In the whole process, an operator only needs to slightly pull or push the upper ends of the first support arm and the second support arm 11 or the technetium barrel main body, so that the loading or unloading of the technetium barrel can be easily realized, the operation process is simple and convenient, the labor intensity is greatly reduced, and the operation efficiency is improved.

Example 2

As shown in fig. 3, the connection of the first and second arms 12 to the technetium bucket 3 in example 1 was changed. In this embodiment, the first and second arms 12 have free ends extending in the horizontal direction and rotating ends rotatably connected to the first and second support arms 11, the free ends can be fitted to and form a tight fit with the two side surfaces of the upper end of the technetium bucket, and the first and second support arms 11 can abut against and support the protrusions on the two sides of the upper end of the technetium bucket and tightly fit with the side walls on the two sides of the upper end of the technetium bucket. When loading the fixed technetium bucket, the operator only needs to close the opened first and second arms 11 to the technetium bucket side and tighten the technetium bucket, and when unloading the technetium bucket, the operator only needs to open the first and second arms 11 to release the technetium bucket. The rotational connection between the first and second arms 12 and the support arm assembly can be achieved by conventional means such as gears, etc., so that the first and second arms 12 do not loosen when they hold the technetium bucket tightly, thereby ensuring the stability and reliability of the technetium bucket transferring process.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
