A vertical movement component is provided on the support member, and a horizontal movement component is provided behind the support member. This device effectively solves the problem of the bulky and difficult-to-handle radioactive source containers in the prior art. However, it is difficult to meet the lifting and placement requirements of different heights and lateral positions, thus affecting the efficiency of radioactive source handling. Utility Model Content

[0004] The purpose of this invention is to provide a novel radioactive source lifting device to solve the problem that the existing technology is unable to meet the lifting and placement needs of different heights and lateral positions, thus affecting the efficiency of radioactive source handling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the invention, a novel radioactive source lifting device includes a lifting frame 2 and a PLC control cabinet located on the side wall. A first slider 4 is threaded onto the side wall of the lifting frame 2 via a first lead screw 3, and a lifting support frame 5 is fixed between two first sliders 4. A second slider 8 is threaded onto the inner wall of the lifting support frame 5 via a second lead screw 7, and a transverse plate 6 is fixed between two second sliders 8. Two sets of first lead screws 3 and second lead screws 7 are arranged in parallel, and the included angle between the first lead screw 3 and the second lead screw 7 is ninety degrees. This results in high transmission stability and convenient and quick operation. Two third sliders 10 are provided on the lower side of the moving plate 6 via a third screw 9 with opposing threads. The lower end of the third slider 10 is provided with a first positioning clamp 12 via a connecting rod 11. The two first positioning clamps 12 are moved and adjusted in opposite directions by the third screw 9, which can clamp and fix both ends of the radiation source. The lifting support frame 5 is raised and lowered to a certain height by the first screw 3. The transverse moving plate 6 and the radiation source are moved laterally by the second screw 7 to adjust the lateral placement position, thereby meeting the lifting and placement needs of different heights and lateral positions, which is beneficial to improving the efficiency of radiation source handling.

[0022] like Figure 1 and Figure 2 As shown, in order to facilitate the movement and handling of the lifting equipment, a bottom support plate 1 is provided at the lower end of the lifting frame 2, and a roller 17 is provided on the lower side of the bottom support plate 1 via the lower bracket 16, which makes it easy to move and handle the lifting equipment, and the roller 17 is a self-locking pulley.

[0023] like Figure 1 and Figure 3As shown, in order to improve the stability of the radioactive source clamping and fixing, two fourth sliders 13 are provided on the inner side of the first positioning clamping plate 12 through the fourth lead screw 18 with opposing threads. A second positioning clamping plate 15 is provided on one side of the fourth slider 13 through the fixed shaft 14. The second positioning clamping plate 15 is an arc-shaped clamping plate, and an anti-slip pad is provided in the arc-shaped clamping groove of the second positioning clamping plate 15. This allows the two fourth sliders 13 and the two second positioning clamping plates 15 to move and adjust in opposite directions through the fourth lead screw 18, thereby clamping and fixing both sides of the end of the radioactive source, which facilitates the improvement of the stability of the radioactive source clamping and fixing, and improves the safety of lifting and transporting.

[0024] like Figure 2 and Figure 3 As shown, in order to drive the two clamping plates to move towards each other for adjustment, two opposite external threads are provided on the outer sides of both ends of the fourth screw 18 and the third screw 9. A servo motor is connected to one end of the screw, which makes it easy to drive the two clamping plates to move towards each other for adjustment, thereby facilitating the clamping and fixing of the radiation source.

[0025] The working principle and usage process of this utility model are as follows: During use, since the lower side of the transverse plate 6 inside the lifting frame 2 is provided with two third sliders 10 and two first positioning clamps 12 through the opposing threads of the third screw 9, the two first positioning clamps 12 can be moved and adjusted in opposite directions by the third screw 9 to clamp and fix both ends of the radiation source. Then, the lifting support frame 5 is lifted and adjusted to a certain height by the first screw 3. The transverse plate 6 and the radiation source are then moved and adjusted to the lateral placement position by the second screw 7, thereby meeting the lifting and placement needs of different heights and lateral positions, which is beneficial to improving the efficiency of radiation source handling.
