Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The following gives specific embodiments.

[0021] See Figures 1 to 4 , in the embodiment of the present utility model, an industrial CT non-destructive testing device includes an industrial CT machine body 1, isolation door panels 2, a pressing rod 3, a button 4, an alarm lamp 5, a radiation monitor 6, a bidirectional moving mechanism 7, and a leveling mechanism 8. There are two isolation door panels 2 arranged on the front side of the industrial CT machine body 1. The isolation door panels 2 are made of lead plates, so that they have a good function of isolating radiation. A pressing rod 3 is installed on one isolation door panel 2, and a button 4 is installed on the other isolation door panel 2. The pressing rod 3 is directly opposite to the button 4. An alarm lamp 5 is installed on the top of the industrial CT machine body 1. The alarm lamp 5 is electrically connected to the button 4 through a wire. When not affected by external force, the button 4 is in a normally open state and the alarm lamp 5 keeps flashing. A bidirectional moving mechanism 7 for driving the two isolation door panels 2 to move is installed on the industrial CT machine body 1. Leveling mechanisms 8 are installed at the four top corners of the bottom of the industrial CT machine body 1. When in use, the two isolation door panels 2 are opened. At this time, the alarm lamp 5 is in an on state and keeps flashing to remind people that the isolation door panels 2 are not closed. The material is placed into the industrial CT machine body 1 for testing. After the material is placed, the two isolation door panels 2 are driven by the bidirectional moving mechanism 7 to approach each other, so that the two isolation door panels 2 block the front end of the industrial CT machine body 1 to prevent radiation from leaking. When the two isolation door panels 2 are closed together, the pressing rod 3 presses on the button 4, and the alarm lamp 5 is turned off. When people see that the alarm lamp 5 is turned off, it means that the isolation door panels 2 are completely closed, and the industrial CT machine body 1 can be started for testing to improve safety.

[0022] The bidirectional moving mechanism 7 includes: a driving motor 701, a bidirectional screw 702, a first external thread 703, a second external thread 704, a first threaded block 705, a second threaded block 706, an adapter plate 707, a slider 708 and a slide rail 709. The driving motor 701 is fixed on the industrial CT machine body 1. The bidirectional screw 702 is rotatably connected to the industrial CT machine body 1. The output shaft of the driving motor 701 is connected to the bidirectional screw 702. The left half of the bidirectional screw 702 is provided with a first external thread 703, and a first threaded block 705 that matches it is installed on the outside of the first external thread 703. The right half of the bidirectional screw 702 is provided with a second external thread 704, and a second threaded block 706 that matches it is installed on the outside of the second external thread 704. A transfer plate 707 is fixed to the lower sides of both the first threaded block 705 and the second threaded block 706. Each transfer plate 707 is fixed to an isolation door panel 2. A slider 708 is installed at the bottom of each transfer plate 707. The slider 708 is slidably installed on the slide rail 709. The slide rail 709 is fixed to the industrial CT machine body 1. The first external thread 703 and the second external thread 704 have opposite helix directions, so that when the bidirectional screw 702 rotates, the moving directions of the first threaded block 705 and the second threaded block 706 are opposite. When in use, the driving motor 701 drives the bidirectional screw 702 to rotate. The rotation of the bidirectional screw 702 drives the first threaded block 705 and the second threaded block 706 to move towards each other. The first threaded block 705 and the second threaded block 706 drive the two isolation door panels 2 to move towards each other.

[0023] The leveling mechanism 8 includes: a support frame 801, a threaded sleeve 802, a handle 803, a threaded rod 804 and a limiting rod 805. A threaded sleeve 802 is rotatably connected to the support frame 801. A handle 803 is fixed to the outside of the threaded sleeve 802. A threaded rod 804 is installed inside the threaded sleeve 802. The top of the threaded rod 804 is fixed to the industrial CT machine body 1. A limiting rod 805 inserted into the support frame 801 is fixed to the bottom of the threaded rod 804. The limiting rod 805 is slidably connected to the support frame 801. A limiting chute 8011 for the up and down movement of the limiting rod 805 is provided inside the support frame 801. The movement of the threaded rod 804 is restricted by the limiting rod 805 so that it cannot rotate but can only move in a straight line. When in use, the handle 803 is rotated to drive the threaded sleeve 802 to rotate. The rotation of the threaded sleeve 802 drives the threaded rod 804 to move up and down. The threaded rod 804 drives a corner of the industrial CT machine body 1 to move up and down. By operating the four leveling mechanisms 8 in this way, the industrial CT machine body 1 is leveled.

[0024] A radiation monitor 6 is installed on the top of the industrial CT machine body 1. The radiation monitor 6 detects the radiation around the industrial CT machine body 1 to promptly discover abnormal radiation leakage.

[0025] Working principle: When using this industrial CT non-destructive testing equipment, turning the handle 803 drives the threaded sleeve 802 to rotate. The rotation of the threaded sleeve 802 drives the threaded rod 804 to move up and down, and the threaded rod 804 drives a corner of the industrial CT machine body 1 to move up and down. By operating the four leveling mechanisms 8 in this way, the industrial CT machine body 1 is leveled, so that the placement of the industrial CT machine body 1 is more stable. Open the two isolation door panels 2. At this time, the alarm lamp 5 is in the on state and keeps flashing to remind people that the isolation door panels 2 are not closed. Then, place the material into the industrial CT machine body 1. After the material is placed, the two isolation door panels 2 are driven to approach each other by the bidirectional moving mechanism 7, so that the two isolation door panels 2 block the front end of the industrial CT machine body 1 to prevent radiation leakage. When the two isolation door panels 2 are closed together, the pressing rod 3 presses on the button 4, and the alarm lamp 5 is turned off. When people see that the alarm lamp 5 is turned off, it means that the isolation door panels 2 are completely closed, and the industrial CT machine body 1 can be started for detection to improve safety.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
