[0038] Example 1

[0039] A specific embodiment of the present invention discloses a lead room system for industrial CT detection, such as Figure 1 As shown, it includes: an entrance lead door 1, a shielding channel 2, a main lead room 3, a leveling device 4 and an exit lead door 5; two groups of the shielding channels 2 are symmetrically arranged on both sides of the main lead room 3; the entrance lead door 1 is installed at the port of one group of shielding channels 2, and the exit lead door 5 is installed at the port of the other group of shielding channels 2; a leveling device 4 is installed below the shielding channel 2 to adjust the height of the shielding channel 2; the shielding channel 2 is a multi-modular assembly structure.

[0040] The lead room system for industrial CT detection of the present invention is mainly aimed at preventing X-ray leakage when the X-ray source is turned on to detect the workpiece during the CT detection process. The channel length can be modeled and spliced ​​according to the use requirements, and can adapt to CT detection of workpiece products of different sizes.

[0041] During the inspection project, the entrance lead door 1 is opened, the workpiece enters the shielding channel 2 from the entrance, the entrance lead door 1 is closed, the workpiece is transmitted to the position of the main lead room 3 through the transmission system inside the lead room system, the X-ray is turned on to start the inspection, and the exit lead door 5 is punched after the inspection. After the workpiece inspection is completed, it leaves the shielding channel through the exit lead door 5. The shielding channel 2 composed of modular lead channels is docked and installed with the main lead room 3, and the leveling device 4 is used to level the shielding channel 2 to ensure that the joints are uniform and there will be no shielding failure.

[0042] In this embodiment, the leveling device 4 is evenly arranged at the bottom of the shielding channel 2 according to the force conditions, supports the weight of the shielding channel 2, and adjusts the height according to the horizontality of each modular channel to ensure that the modular channels are in the same height plane.

[0043] Furthermore, the leveling device 4 is symmetrically arranged in two groups at the bottom of the shielding channel 2, with multiple leveling devices arranged in each group. Figure 2 As shown, the leveling device 4 includes: a leveling base 6, an adjusting screw 7 and a leveling pad 8. The adjusting screw 7 is rotatably mounted on the leveling base 6; the adjusting screw 7 is screwed to the leveling pad 8 through a thread, and when the adjusting screw 7 rotates relative to the leveling base 6, it can drive the leveling pad 8 to slide up and down relative to the leveling base 6.

[0044] Furthermore, the upper end of the leveling base 6 is provided with an inclined surface; the leveling pad 8 is a wedge-shaped structure; the side of the wedge-shaped structure fits the inclined surface. When the leveling pad 8 moves up and down, the side of the wedge-shaped structure can slide along the inclined surface of the leveling base 6, thereby changing the overall height of the leveling device 4 and supporting the shielding channel 2, thereby achieving height adjustment of the shielding channel 2.

[0045] Furthermore, the leveling base 6 is provided with a U-shaped groove or a U-shaped hole, the adjusting screw 7 is rotatably installed in the U-shaped groove or the U-shaped hole, and a positioning nut is screwed on the adjusting screw 7 through a thread, and the positioning nut is pressed against the surface of the leveling base 6.

[0046] Preferably, if Figure 2 As shown, two positioning nuts are provided, which are respectively provided on the upper and lower surfaces of the U-shaped hole / U-shaped groove, and can limit the adjustment screw 7 from being separated from the U-shaped groove or U-shaped hole, and can also limit the relative displacement of the adjustment screw 7 in the vertical direction relative to the leveling base 6, so that the adjustment screw 7 can provide a stable support effect for the adjustment pad 8. Preferably, the positioning nut is connected to the adjustment screw 7 by threads, and further, after the position of the positioning nut on the adjustment screw is adjusted to the right position, the two are fixed as one by welding.

[0047] During adjustment, the leveling base 6 and the adjusting pad 8 are in contact through the inclined surface. When the adjusting screw 7 is rotated by a tool, the distance between the adjusting screw 7 and the adjusting pad 8 changes, and at the same time, the adjusting screw 7 slides in the U-shaped groove or U-shaped hole to pull the wedge-shaped adjusting pad 8 to move along the inclined surface of the leveling base 6; since the adjusting pad 8 and the leveling base 6 are in contact with the inclined surface, the overall height change can be achieved by pulling the wedge-shaped adjusting pad 8 to slide with external force, thereby realizing the height adjustment function.

[0048] Furthermore, the shielding channel 2 includes: a first modular channel 9, a first connecting bolt 10, and a second modular channel 11. The first modular channel 9 and the second modular channel 11 are connected and fixed by the first connecting bolt 10. Figure 3 As shown, the docking interface between the first modular channel 9 and the second modular channel 11 adopts a maze design. After docking, the leveling device 4 at the bottom is adjusted to ensure that the first modular channel 9 is horizontally aligned with the second modular channel 11. After docking, the first modular channel 9 and the second modular channel 11 are connected together with the first connecting bolt 10. Since the interface cross-section of the two is a Z-shaped bending structure, the rays can be blocked and shielded to ensure that no X-ray leakage occurs.

[0049] Furthermore, a first docking portion is provided at one end of the first modular channel 9 ; a second docking portion is provided at one end of the second modular channel 11 ; and the first docking portion and the second docking portion are connected as a whole through a first connecting bolt 10 after docking.

[0050] In this embodiment, the first docking portion includes: a first annular plate and a docking tube plate; the first annular plate and the docking tube plate are perpendicular to each other and are an integral structure; specifically, the first annular plate, the docking tube plate and the first modular channel 9 are fixedly connected or are an integral structure, the outer side of the first annular plate is connected to the first modular channel 9, and the inner side of the first annular plate is fixedly connected to the end of the docking tube plate, such as Figure 3 shown.

[0051] In this embodiment, the second docking portion includes: a second annular plate; the second annular plate can be sleeved on the outside of the docking tube plate; the first annular plate and the second annular plate are connected by a first connecting bolt 10. The first docking portion and the edge of the first modular channel 9 form a Z-shaped structure; the second annular plate and the edge of the second modular channel 11 form an L-shaped structure; and the outer side surface of the second annular plate is in contact with the outer side surface of the first annular plate.

Specifically, an internal cavity for installing the jaw opening and closing mechanism is provided inside the entrance jaw and the exit jaw 5, and the passage window is provided through the internal cavity.

[0054] like Figure 4As shown, the lead door opening and closing mechanism includes: a driving motor 19, a transmission mechanism, a lead door guide rail 15 and a shielding lead door 22; the lead door guide rail 15 is symmetrically arranged in two pieces inside the entrance lead door 1 or the exit lead door 5; the shielding lead door 22 is slidably installed on the lead door guide rail 15; the driving motor 19 can drive the shielding lead door 22 to slide up and down along the lead door guide rail 15 through the transmission mechanism.

[0055] Furthermore, if Figure 4 As shown, the transmission mechanism includes: a motor gear 18, a transmission gear 20, a rotating shaft 16 and two sets of gear toothed belt mechanisms; the motor gear 18 is fixedly connected to the output shaft of the drive motor 19 and can rotate under the drive of the drive motor 19; both ends of the rotating shaft 16 are rotatably mounted in the internal cavity of the inlet jaw 1 or the outlet jaw 5 through bearings 21; the transmission gear 20 is meshed with the motor gear 18 for transmission, and the transmission gear 20 is fixedly connected to the rotating shaft 16; the gear toothed belt mechanism includes: a first synchronous gear 12, a synchronous belt 13 and a second synchronous gear 17; the synchronous belt 13 is sleeved and mounted on the outside of the first synchronous gear 12 and the second synchronous gear 17, and the three are meshed for transmission; the second synchronous gear 17 is fixedly mounted on the rotating shaft 16, the synchronous belt 13 is fixedly connected to the shielding jaw 22, and when the synchronous belt 13 is driven by the first synchronous gear 12 and the second synchronous gear 17, it can drive the shielding jaw 22 to move up and down.

[0056] Specifically, the first synchronous gear 12 is rotatably mounted on the side wall of the inner cavity of the inlet jaw 1 or the outlet jaw 5 .

[0057] Specifically, after the driving motor 19 is running, it drives the motor gear 18 to rotate. The motor gear 18 meshes with the transmission gear 20 and drives the rotating shaft 16 to rotate through the transmission gear 20. The rotation of the rotating shaft 16 simultaneously drives the two sets of gear belt mechanisms on both sides to rotate. The rotation of the synchronous belt 13 simultaneously drives the shielding lead door 22 to move synchronously, thereby realizing the up and down movement of the shielding lead door 22 and realizing the switching action.

[0058] Specifically, a support roller 23 is installed at the upper end of the shielding lead door 22 to support the workpiece when the channel window is open. Figure 4 shown.

[0060] During implementation, the shielding lead door 22 is connected to the lead door guide rail 15 to ensure smooth movement of the shielding lead door 22. When the shielding lead door 22 drops to the lowest position, the support roller 23 above the shielding lead door 22 is flush with the height of the conveyor belt outside the shielding channel. When the test workpiece moves to the shielding door through the conveyor belt, the workpiece can be smoothly transported to the support roller 23 until the workpiece completely passes through the shielding lead door 22. After the workpiece passes through the shielding lead door 22, the drive motor 19 reverses and drives the shielding lead door 22 to move upward to the highest point, sealing the channel window to prevent radiation leakage.

[0061] In this embodiment, the shielding channel 2 adopts a segmented design and can be spliced ​​into a shielding lead room according to implementation needs, which effectively improves the detection capability of the entire equipment; the shielding channel length can be adjusted according to the length of the workpiece to be detected during industrial CT detection, thereby preventing the leakage of X-rays during CT detection and improving the application capability of the product.

[0066] Specifically, Figure 5 , Figure 6 As shown, the adjustment channel includes: a main shielding channel 25 and a secondary shielding channel 26 nested inside the main shielding channel 25; further, a plurality of movable beams 27 are arranged on the top of the main shielding channel 25, and the movable beams 27 are floatingly installed on the top of the main shielding channel 25, and can be fixedly connected with the secondary shielding channel 26 by a second connecting bolt 29.

[0067] Specifically, Figure 6 As shown, a plurality of movable cross beams 27 are arranged along the axis direction of the main shielding channel 25; preferably, the plurality of movable cross beams 27 are arranged at equal intervals. Figure 5 , Figure 6 As shown, the main shielding channel 25 and the auxiliary shielding channel 26 are both rectangular lead tube structures.

[0068] Furthermore, a rectangular slot 33 is provided on the side of the movable crossbeam 27 , and the length of the movable crossbeam 27 is smaller than the width of the inner cavity of the secondary shielding channel 26 , so that the top plate of the secondary shielding channel 26 can be inserted into the rectangular slot 33 .

[0069] Furthermore, if Figure 6 , Figure 8 , Fig.10 As shown, a third threaded hole 38 is provided on the top plate of the secondary shielding channel 26; when the top plate of the secondary shielding channel 26 is engaged with the rectangular slot 33 on the side of the movable crossbeam 27, the third threaded hole 38 can be aligned with the first threaded hole 32, and then the second connecting bolt 29 can be screwed into the first threaded hole 32 and the third threaded hole 38, so as to realize the fixed connection between the main shielding channel 25 and the secondary shielding channel 26. Preferably, a plurality of the first threaded holes 32 are provided in the axial direction of the movable crossbeam 27, and correspondingly, a plurality of the third threaded holes 38 are also provided on the secondary shielding channel 26; and then the secondary shielding channel 26 can be fixedly connected with the movable crossbeam 27 through a plurality of second connecting bolts 29.

[0070] Specifically, Figure 7 As shown, a rectangular through hole 37 for installing the movable crossbeam 27 is provided at the top of the main shielding channel 25. The movable crossbeam 27 is movably installed in the rectangular through hole 37 and can slide up and down along the rectangular through hole 37, and the installation state of the movable crossbeam 27 on the main shielding channel 25 is adjusted, and different movable crossbeams 27 are switched to be connected with the auxiliary shielding channel 25, so as to realize multi-level adjustment of the overall length of the channel.

Specifically, the lower end surface of the adjusting bolt 28 is pressed against the bottom surface of the first rectangular slot, and when the adjusting bolt 28 is rotated to make its lower end protrude from the lower surface of the upper wing plate 35, the adjusting bolt 28 can drive the movable crossbeam 27 to move upward relative to the main shielding channel 25, and then drive the lower wing plate 36 to be stuck in the second rectangular slot 31.

[0075] In this embodiment, a plurality of floating beams 27 are arranged on the main shielding channel 25, which are fixedly connected to the auxiliary shielding channel 26 through the floating beams 27, so that the auxiliary shielding channel 26 is nested inside the main shielding channel 25 and the length of the adjustment channel composed of the two can be adjusted in multiple levels, thereby solving the problem of the incompatibility between the length of the channel and the length of the workpiece to be detected. At the same time, the shielding channel with a multi-level adjustable length is designed to adapt to sites under different environments and can realize the installation of the lead room system under limited space adjustment.

[0076] In this embodiment, a movable crossbeam 27 is provided to float up and down in the rectangular through hole 37, and an upper wing plate 35 and a lower wing plate 36 are provided on the movable crossbeam 27; when the upper wing plate 35 of the movable crossbeam 27 is engaged with the first rectangular slot 30, multi-layer shielding of internal X-rays can be achieved, and the secondary shielding channel 26 can be inserted into the rectangular slot 33 on the side of the movable crossbeam 27 and fixedly connected thereto; when the lower wing plate 36 of the movable crossbeam 27 is engaged with the second rectangular slot 31, the lower wing plate 36 and the main body of the main shielding channel 25 can achieve multi-layer shielding of internal X-rays, and at the same time, the secondary shielding channel 26 can cross the movable crossbeam 27 and be mutually connected with the main shielding channel 25, so that the movable crossbeam 27 of the present invention can have the function of connecting with the secondary shielding channel 26 to realize multi-stage adjustment of the overall length of the channel, and the movable crossbeam 27 can achieve effective shielding of X-rays regardless of whether it is in an upward or downward floating state.
