[0002] During industrial CT operation, lead shielding doors need to be installed at the entrance of the lead room to prevent radiation leakage and potential environmental damage. Current technologies often use left-right opening doors (i.e., horizontal opening doors) to control the opening and closing of the lead room entrance. Left-right opening lead shielding doors typically occupy a large amount of horizontal space, which is inconvenient in areas with limited horizontal space. Utility Model Content

[0003] Based on the above analysis, this utility model aims to provide a lead-shielded automatic lifting door device to solve the problem of limited lateral space at the entrance of industrial CT scanners and inconvenient opening and closing of shielded doors in the prior art.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] An automatic lifting door device with lead shielding includes a shielding door, a drive unit, a grating, and a controller. Both the shielding door and the drive unit are installed at the entrance of an industrial CT inspection equipment. The shielding door is capable of sliding up and down. The drive unit is connected to the shielding door and drives it to rise and fall, thus opening and closing the door. The grating is located at the top of the shielding door and connected to the controller. The grating detects whether a workpiece to be tested passes through the shielding door and feeds the signal back to the controller. The controller is connected to the drive unit and controls its operation, thereby automatically controlling the rising and falling of the shielding door.

[0006] Furthermore, the lifting door device also includes support wheels, which are located at the top of the door body. The support wheels can move between the two conveyor belts in the industrial CT inspection equipment and are flush with the upper surfaces of the two conveyor belts.

[0007] Furthermore, the grating includes a primary emitting grating and a receiving grating, wherein the primary emitting grating is used to emit a light beam and the receiving grating is used to receive the light beam.

[0008] Furthermore, the main beam grating is located at the top of the door, and the receiving beam grating is located above the entrance of the industrial CT inspection equipment.

[0009] Furthermore, the shielding door includes a door body and a guide rail.

[0010] Furthermore, the guide rail is installed on the entrance of the industrial CT inspection equipment; the door is installed on the guide rail and can slide up and down along the guide rail.

[0011] Furthermore, the driving device includes a motor, a drive gear, a first transmission wheel, a second transmission wheel, and a synchronous belt.

[0012] Furthermore, the synchronous belt is sleeved on the first transmission wheel and the second transmission wheel, and the synchronous belt is fixedly connected to the door body.

[0014] Furthermore, the drive device also includes a synchronizing rod; two of each of the first transmission wheel, the second transmission wheel, and the synchronizing belt are provided, and the two first transmission wheels are fixedly connected to each other by the synchronizing rod.

[0015] The technical solution of this utility model can achieve at least one of the following effects:

[0016] (1) This utility model discloses a lead-shielded automatic lifting door device, comprising a shielding door, a drive device, a grating, and a controller. Both the shielding door and the drive device are installed at the entrance of an industrial CT inspection equipment. The shielding door can slide up and down. The drive device is connected to the shielding door and is used to drive the shielding door to rise and fall, thus opening and closing the door. The grating is located at the top of the shielding door and is connected to the controller.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0026] Example 1

[0027] A specific embodiment of this utility model discloses a lead-shielded automatic lifting door device, installed between two conveyor belts at the entrance of an industrial CT inspection equipment, for controlling the opening and closing of the entrance to the industrial CT inspection equipment; such as Figure 1 As shown, the lifting door device includes a shielding door 1, a drive device 2, a grating 3, and a controller. Both the shielding door 1 and the drive device 2 are installed at the entrance of the industrial CT inspection equipment. The shielding door 1 can slide up and down. The drive device 2 is connected to the shielding door 1 and is used to drive the shielding door 1 to rise and fall, thus opening and closing the door. The grating 3 is located on the top of the shielding door 1 and is connected to the controller. The grating 3 is used to detect whether the workpiece to be tested has passed through the shielding door 1 and feeds the signal back to the controller. The controller is connected to the drive device 2 and is used to control the action of the drive device 2, thereby automatically controlling the rise and fall of the shielding door 1 and realizing the automatic opening and closing of the entrance to the industrial CT inspection equipment. Compared with the prior art, this reduces the horizontal space occupied and facilitates the opening and closing of the shielding door 1.

[0028] Preferably, such as Figure 2As shown, the shielding door 1 includes a door body 11 and a guide rail 12. The guide rail 12 is installed on the entrance of the industrial CT inspection equipment and is vertically arranged. The door body 11 is installed on the guide rail 12 and can slide up and down along the guide rail 12 to realize the smooth lifting and lowering movement of the door body 11, thereby controlling the opening and closing of the entrance of the industrial CT inspection equipment, thus reducing the space occupied laterally.

[0029] Preferably, such as Figure 3 As shown, the driving device 2 includes a motor 21, a drive gear 22, a first transmission wheel 23, a second transmission wheel 24, and a synchronous belt 25. The synchronous belt 25 is sleeved on the first transmission wheel 23 and the second transmission wheel 24, and is fixedly connected to the door body 11. The second transmission wheel 24 is installed above the entrance of the industrial CT inspection equipment. The first transmission wheel 23 is fixedly connected to the drive gear 22, the drive gear 22 is connected to the output end of the motor 21, and the motor 21 is connected to a controller. The controller controls the rotation of the motor 21, thereby controlling the rotation of the synchronous belt 25, and thus controlling the lifting and lowering of the door body 11, so as to facilitate the opening and closing of the entrance of the industrial CT inspection equipment.

[0030] Preferably, the driving device 2 further includes a synchronizing rod 26; two of each of the first transmission wheel 23, the second transmission wheel 24, and the synchronizing belt 25 are provided, and the two first transmission wheels 23 are fixedly connected by the synchronizing rod 26, thereby realizing the synchronous driving of the two first transmission wheels 23 to rotate, and then driving the two synchronizing belts 25 to rotate, thereby driving the door body 11 to rise and fall through the two synchronizing belts 25, improving the smoothness of the door body 11's movement.

[0031] Preferably, the grating 3 includes a main emission grating and a receiving grating. The main emission grating is disposed at the top of the door 11, and the receiving grating is disposed above the entrance of the industrial CT inspection equipment and opposite to the main emission grating. The main emission grating is used to emit a light beam, and the receiving grating is used to receive the light beam. When the receiving grating receives all the light beams emitted by the main emission grating, it indicates that the workpiece to be tested has passed through the entrance of the industrial CT inspection equipment. The receiving grating is connected to the controller and is used to transmit the light beam signal received from the main emission grating to the controller, and the controller controls the door 11 to rise and fall, thereby realizing the automatic opening and closing of the entrance of the industrial CT inspection equipment.

[0032] Preferably, the lifting door device further includes a support wheel 4, which is located at the top of the door body 11. When the door body 11 is lowered, the support wheel 4 can move between the two conveyor belts in the industrial CT inspection equipment and be flush with the upper surface of the two conveyor belts to fill the gap between the two conveyor belts. This prevents smaller workpieces to be tested from leaking into the gap between the two conveyor belts, allowing smaller workpieces to be tested to pass smoothly through the top of the door body 11 and enter the industrial CT inspection equipment for inspection, thereby expanding the workpiece inspection range of the industrial CT inspection equipment.

[0033] In use, the motor 21 drives the drive gear 22 to rotate, thereby controlling the synchronous belt 25 to rotate, which in turn drives the door 11 to rise and fall, realizing the opening and closing action. When the door 11 is lowered to the lowest position, the top of the support wheel 4 above the door 11 is level with the height of the two conveyor belts in the industrial CT inspection equipment, so that the workpiece to be tested can pass smoothly through the gap between the two conveyor belts, that is, through the door 11. After the workpiece to be tested passes through the door 11, the receiving grating receives all the light beams emitted by the main beam grating and transmits the received main beam signal to the controller. The controller controls the motor 21 to reverse, thereby driving the door 11 to move upward to the highest point, sealing the entrance of the industrial CT inspection equipment and preventing radiation leakage.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
