[0039] Reference Figure 1-Figure 5 The utility model provides an electron accelerator centering measurement bracket, comprising: a group of parallel side frames 1, a top frame 2, a laser rangefinder 3, and a sliding frame 8.

[0040] Among them, the top plate frame 2 is fixedly installed on the top of the side frame 1, and the end of the top plate frame 2 extends to the outside of the side frame 1, and a mounting hole is opened at the top of the top plate frame 2 and on the outside of the side frame 1. The top of the laser rangefinder 3 and the bottom of the top plate frame 2 on the outside of the side frame 1 are fixedly installed by bolts, that is, screws are passed through the mounting holes and then threadedly connected with the laser rangefinder 3, so that the laser rangefinder 3 is fixed to the top plate frame 2, and the laser rangefinder 3 measures distance toward the outside.

[0041] One way is: when the length of the roller is known, it is necessary to ensure that the distance measured by the laser rangefinder 3 meets the requirement that the measuring bracket is located in the middle of the roller.

[0042] Another way is: two laser rangefinders 3 are provided, and the two laser rangefinders 3 are respectively fixedly mounted at the two ends of the top plate frame 2, and the distances measured by the two laser rangefinders 3 are equal, so as to determine that the measuring bracket is located in the middle of the drum.

[0043] The sliding frame 8 is slidably connected to the top plate frame 2, and the sliding frame 8 can be fixed with the top plate frame 2 at any position within the sliding range.

[0044] When in use, the user relies on the assistance of the laser rangefinder 3 to locate the centering measurement bracket in the middle of the conveying roller, and observes the positions of the scanning box and the top plate frame 2 to determine whether the scanning box is centered; then slide the two sets of sliding frames 8 upwards to make the top of the sliding frames 8 rest against the bottom of the scanning box (against the titanium window flange to avoid contact with the titanium film), then remove the sliding frames 8, and determine whether the scanning box is level based on the length of the two sliding frames 8 extending upwards.

[0045] In one embodiment, a plurality of parallel dosage strips 4 are fixedly connected to the top of the top plate frame 2 , and the dosage strips 4 are perpendicular to the length direction of the top plate frame 2 .

[0046] By observing that the dosage strip 4 is parallel to the scanning window, it is helpful to determine the centering position of the scanning box.

[0047] In one embodiment, a foot plate 5 is fixedly connected to the bottom of the side frame 1. The foot plate 5 is relatively wide and can be well supported on the drum. A level 7 is provided on the upper surface of the foot plate 5 to assist in determining whether the drum is in a horizontal state and to assist in observing whether the top plate frame 2 of the centering measurement bracket is in a horizontal state.

[0048] In one embodiment, a beam plate 6 is fixedly connected between the multiple side frames 1 and near the foot plate 5 to increase the structural strength between the multiple side frames 1, making the structure more stable and less prone to deformation.

[0049] In one embodiment, a protective head 9 is fixedly connected to the top of the sliding frame 8 to prevent the top of the sliding frame 8 from strongly colliding with the titanium window and affecting the scanning box.

[0050] In one embodiment, a first sliding opening is opened at the top of the top plate frame 2, and the sliding frame 8 is located in the first sliding opening and slides along the up and down directions. A stabilizing frame 10 is fixedly installed on the inner side of the side frame 1, and a second sliding opening is formed between the stabilizing frame 10 and the side frame 1. The sliding frame 8 is located in the second sliding opening and slides along the up and down directions. An elastic extrusion member 11 is fixedly connected to the bottom of the sliding frame 8.

[0051] The sliding frame 8 is guided by the first sliding opening and the second sliding opening, so that the sliding frame 8 located above the first sliding opening is in a vertical state, and one side of the elastic extrusion member 11 squeezes the side frame 1, so that the sliding frame 8 located below the second sliding opening is slightly deformed, so that there is also squeezing between the sliding frame 8 and the second sliding opening, thereby preventing the sliding frame 8 from sliding down under the action of gravity. When the user pushes upward with force, the friction between the sliding frame 8 and the second sliding opening and the friction between the elastic extrusion member 11 and the side frame 1 can be overcome, thereby pushing the sliding frame 8 upward.

[0052] Specifically, the elastic extrusion member 11 includes: a mounting vertical plate 113 , a metal inclined plate 112 , a rubber head 111 and a limiting nail 115 .

[0053] The mounting plate 113 is fixedly connected to the side of the sliding frame 8, the top of the metal inclined plate 112 is fixedly connected to the bottom of the mounting plate 113, a sliding hole 114 is provided on the side of the metal inclined plate 112, the mounting plate 113 and the metal inclined plate 112 are an integrated structure, the rubber head 111 is located at the bottom of the sliding frame 8, and the side of the rubber head 111 is fixedly connected to the bottom of the metal inclined plate 112, one side of the rubber head 111 is against the inner side of the side frame 1, the limiting nail 115 passes through the sliding hole 114, and is threadedly connected to the sliding frame 8, and the end of the limiting nail 115 limits the metal inclined plate 112 from moving in the direction away from the sliding frame 8.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
