Technical Field

[0001] The utility model relates to the technical field of industrial irradiation, in particular to a tool for accurately measuring the lifting position of a cobalt source frame. Background Art

[0002] Under normal operating conditions, a large-scale cobalt source irradiation device usually contains tens to millions of Curies of cobalt source. The cobalt source rack is divided into single-plate source rack, parallel double-plate source rack, parallel double-plate source rack and other plate source racks. For this type of plate source rack type cobalt source irradiation device.

[0003] Most of the existing cobalt source racks are fixed by traction with steel wire ropes. Marks are made on the steel wire ropes during traction, and the lifting and lowering positions of the cobalt source racks are observed by observing the moving positions of the marks. However, the steel wire ropes will produce irreversible shrinkage reactions when exposed to radiation for a long time, which will have a certain impact on the detection results. In addition, the traditional measurement method cannot ensure the horizontal state of the cobalt source rack, which will have a certain impact on the irradiation effect of the equipment.

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 tool for accurately measuring the lifting position of the cobalt source rack in this embodiment includes a horizontal base 1, a fixed base 2 is arranged below the horizontal base 1, screws 17 are arranged at the front, rear and both sides of the top of the fixed base 2, four screws 17 penetrate the horizontal base 1 from bottom to top and extend out of the top of the horizontal base 1, and the outer surfaces of the extended ends of the four screws 17 are provided with downward pressure adjustment buttons 18, and pressure springs 16 are commonly connected at the four corners between the horizontal base 1 and the fixed base 2, and four levels 19 are arranged at the top of the horizontal base 1 near the screw 17. When the fixed base 2 is installed on the top of the platform, the four levels 19 are used to observe whether the horizontal base 1 is in a horizontal state. If the front end of the horizontal base 1 is higher and causes the horizontal base 1 to be not in a horizontal state, the downward pressure adjustment button 18 at the front end can be twisted, and the downward pressure adjustment button 18 is threadedly connected to the screw 17. When the adjusting button 18 is pressed down at 18 o'clock, the horizontal base 1 will be pressed down to make the higher end drop until the horizontal base 1 is adjusted to a horizontal state. Two through columns 3 are arranged on the top of the horizontal base 1. The outer surfaces of the two through columns 3 are sleeved with cobalt source rack positioners 4. The opposite surfaces of the two cobalt source rack positioners 4 are arranged with support blocks 9. The opposite surfaces of the two support blocks 9 are plugged with brackets 13. The opposite surfaces of the two brackets 13 are arranged with U-shaped frames 10. The two cobalt source rack positioners 4 are used together. The cobalt source racks are clamped by the two U-shaped frames 10 to facilitate the lifting and lowering mosquito measurement. A sleeve plate 7 is arranged on one side of any cobalt source rack positioner 4. A scale ruler 6 is plugged into the interior of the sleeve plate 7. A scale display port 8 is arranged at the front end of the sleeve plate 7. The scale display port 8 displays the scale. After the cobalt source rack is installed, the scale is the reference height. When the height of the cobalt source rack after lifting is compared with the reference height, the lifting position can be obtained.

[0022] Specifically, two heightening mounting frames 14 are provided at the front edge and the rear edge of the bottom end of the fixed base 2. The heightening mounting frames 14 heighten the fixed base 2 to facilitate the installation of the measuring tool.

[0023] Furthermore, a limiting top block 5 is provided at the top of each of the two through columns 3, and the limiting top block 5 limits the two cobalt source rack positioners 4 to prevent the cobalt source rack positioners 4 from falling off from the outer surface of the through column 3, thereby ensuring the integrity of the equipment.

[0024] Furthermore, positioning rings 15 are provided on the top and bottom outer surfaces of the four pressure springs 16, which reinforce the pressure springs 16. When the horizontal base 1 is adjusted to a horizontal state, the pressure springs 16 will apply thrust to the horizontal base 1, and the positioning rings 15 will prevent the pressure springs 16 from deviating too much.

[0025] Furthermore, the top and bottom of the two U-shaped frames 10 are detachably mounted with screws 11. When the two U-shaped frames 10 clamp the cobalt source frame, the screws 11 are passed through the top and bottom of the U-shaped frames 10 to connect them. The two U-shaped frames 10 are locked by tightening the nuts to fix the cobalt source frame tightly to prevent it from falling off.

[0026] Furthermore, a cavity compatible with the bracket 13 is provided inside the support block 9, and the top and bottom of the bracket 13 are connected to the support block 9 through the cavity and are provided with an auxiliary spring 12. When fixing the cobalt source frame, the bracket 13 is pushed toward the support block 9, and the auxiliary spring 12 is pulled. After the two U-shaped frames 10 are placed on both sides of the cobalt source frame, the bracket 13 is loosened, and the auxiliary spring 12 releases the elastic force so that the two U-shaped frames 10 clamp the cobalt source frame, and then the screw 11 penetrates the top and bottom of the U-shaped frame 10 to connect, and the two U-shaped frames 10 are locked by tightening the nut to fix the cobalt source frame tightly.

[0027] The method of using the present embodiment is as follows: when fixing the cobalt source frame, the bracket 13 is pushed toward the support block 9, the auxiliary spring 12 is pulled, and the two U-shaped frames 10 are placed on both sides of the cobalt source frame and then the bracket 13 is loosened. The auxiliary spring 12 releases the elastic force so that the two U-shaped frames 10 clamp the cobalt source frame, and then the screw 11 penetrates the top and bottom of the U-shaped frame 10 to connect, and the two U-shaped frames 10 are locked by tightening the nut to fix the cobalt source frame tightly, and then the fixed base 2 is installed on the top of the platform, and the four level gauges 19 are used to observe whether the level base 1 is in a horizontal state, such as water level. When the front end of the flat base 1 is higher and causes the horizontal base 1 to be not in a horizontal state, the downward pressure adjusting button 18 at the front end can be twisted. The downward pressure adjusting button 18 is threadedly connected to the screw 17. When the downward pressure adjusting button 18 is twisted, the downward pressure adjusting button 18 will press down the horizontal base 1 to make the higher end drop until the horizontal base 1 is adjusted to a horizontal state, thereby ensuring that the cobalt source frame is in a horizontal state. After the cobalt source frame is installed, the scale displayed on the scale display port 8 is the reference height. When the cobalt source frame is running and generates a lifting movement, the data on the scale display port 8 will be compared with the reference height to obtain the lifting position.
