DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] like Figures 1 to 4As shown, the cobalt source lifting device of this embodiment includes a frame 1 and a lifting frame 2, the lifting frame 2 is located inside the frame 1, and the objects that need to be sterilized are placed inside the lifting frame 2, and the lifting frame 2 can be lifted and lowered. Two fixed plates 3 are installed on the frame 1 on both sides of the lifting frame 2, and connecting blocks 4 are installed on the upper and lower parts of the middle of both ends of the lifting frame 2. A rack 5 is installed at one end of each of the two connecting blocks 4. The rack 5 is located between the two fixed plates 3, and the connecting block 4 passes through a fixed plate 3 through a movable groove, and the connecting block 4 can move inside the fixed plate 3. A rack 2 6 is installed above one end of the fixed plate 3 on the side of the rack 5 away from the lifting frame 2, and a motor 7 is movably installed on the fixed plate 3 in front of the rack 26, and the motor 7 is connected to The forward and reverse circuit, the motor 7 can rotate forward and reverse, the motor 7 can move up and down on the fixed plate 3, and a gear 8 is installed at the output end of the motor 7, and the gear 8 is meshed with the rack 1 5 and the rack 2 6. The motor 7 drives the gear 8 to rotate, and the gear 8 drives the lifting frame 2 to rise through the rack 1 5. At the same time, the gear 8 rises on the rack 2 6, which can make the lifting frame 2 rise quickly, effectively reducing the waiting time required for the lifting of the lifting frame 2, and effectively speeding up the operation efficiency. The lifting frame 2 at the front and rear ends of the connecting block 4 is installed with mounting plates 9, and the mounting plates 9 are installed with buffer components on the upper and lower sides. The buffer component is used to buffer the impact force when the lifting frame 2 rises and falls, thereby extending the service life of the lifting frame 2.

[0022] Specifically, the front end of the fixed plate 3 in front of the rack 2 6 is installed with a slide rail 11, a slider 12 is slidably installed on the slide rail 11, a mounting seat 13 is installed at the front end of the slider 12, and the motor 7 is installed on the mounting seat 13. When the motor 7 drives the gear 8 to rotate on the rack 2 6, the motor 7 slides on the slide rail 11 through the slider 12, which is convenient for the motor 7 to move. The cable of the motor 7 can be installed by a drag chain, so the cable of the motor 7 will not be entangled.

[0023] Furthermore, the buffer assembly includes a fixed rod 1001, a buffer spring 1002, a limit plate 1003 and a buffer pad 1004. The upper and lower ends of the mounting plate 9 are both equipped with fixed rods 1001, and the buffer spring 1002 is sleeved on the surface of the fixed rod 1001. The limit plate 1003 is detachably installed on the surface of the fixed rod 1001 above the buffer spring 1002. A cushion block 14 is installed on the frame 1 below the limit plate 1003, and the cushion blocks above and below the limit plate 1003 are Through holes 15 are arranged on 14 and the frame 1, and buffer pads 1004 are installed on the upper ends of the pads 14 above and below the limit plate 1003 and the frame 1. When the lifting frame 2 is lifted up and down, the fixing rod 1001 enters into the through hole 15, the limit plate 1003 contacts the lifting frame 2 or the pad 14, and the limit plate 1003 compresses the buffer spring 1002, thereby playing a buffering role to avoid a large impact force when the lifting frame 2 rises and falls.

[0024] Furthermore, the buffer pad 1004 is sleeved on the surface of the through hole 15. The buffer pad 1004 can be made of a soft rubber material. The buffer pad 1004 is in contact with the limit plate 1003. The limit plate 1003 can be partially sunken into the buffer pad 1004, which is similar to a damping effect, thereby absorbing the buffering force and avoiding the impact force on the buffer spring 1002 from being transmitted to cause the lifting frame 2 to vibrate, thereby playing a buffering role.

[0025] Furthermore, thread grooves 16 are provided on the upper surface of the fixing rod 1001, and a fixing nut 17 is threadedly connected to the upper end of the fixing rod 1001 through the thread groove 16. The limiting plate 1003 is installed through the fixing nut 17. The fixing nut 17 can be removed from the fixing rod 1001 by rotating it, and then the limiting plate 1003 is removed, which facilitates the disassembly and replacement of the buffer spring 1002 that has elastic fatigue, effectively ensuring the effective buffering of the buffer assembly and having practicality.

[0026] Furthermore, a shielding layer is installed inside the lifting frame 2, which can shield the rays generated by radiation sterilization. The shielding layer is made of lead material, which can effectively shield the radiation rays, effectively prevent the radiation rays from penetrating, and prevent the rays from affecting the health of the staff.

[0027] The method of using this embodiment is as follows: when the cobalt source lifting device is used, the motor 7 is connected to the power supply through a cable and is controlled by a control switch. When the lifting frame 2 needs to be lifted, the motor 7 is started to rotate, and the motor 7 drives the gear 8 to rotate. The gear 8 drives the lifting frame 2 to rise through the rack 1 5. At the same time, the gear 8 rises on the rack 2 6, which can realize the rapid rise of the lifting frame 2 and effectively speed up the lifting efficiency of the lifting frame 2. When the lifting frame 2 needs to be lowered, the motor 7 is controlled to drive the gear 8 to rotate in the opposite direction. When the lifting frame 2 is lifted, the gear 8 is driven to rotate in the opposite direction. When it drops to the upper and lower limit positions, the fixed rods 1001 in the buffer assemblies on both sides of the lifting frame 2 are inserted into the through holes 15, and at the same time, the limit plates 1003 are in contact with the buffer pads 1004. The limit plates 1003 are under pressure to compress the buffer springs 1002, and the buffer pads 1004 absorb the buffer force, effectively reducing the impact force when the lifting frame 2 rises and falls, and effectively extending the service life of the lifting frame 2. When the items inside the lifting frame 2 are disinfected and sterilized, the shielding layer inside the lifting frame 2 isolates the radiation rays to avoid harm to the health of the staff.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
