[0028] The utility model provides a device for inspecting the curvature of a containment steel lining cylinder wall plate.

[0029] In the embodiment of the present utility model, Figures 1 to 4As shown, the curvature inspection device 10 for the containment steel lining cylinder wall panel includes an inspection component and a support adjustment component. The inspection component includes an arc-shaped fixing sleeve 110 and at least one arc-shaped telescopic plate 120. The curvature of the arc-shaped telescopic plate 120 is the same as that of the arc-shaped fixing sleeve 110. The arc-shaped fixing sleeve 110 has a telescopic cavity 111 extending along its bending direction. The telescopic cavity 111 is provided with a telescopic opening 112 at least at one end along the bending direction of the arc-shaped fixing sleeve 110. The arc-shaped telescopic plate 120 is movably arranged in the telescopic cavity 111. The arc-shaped telescopic plate 120 extends from the telescopic opening 112 or retracts into the telescopic cavity 111. The support adjustment component is connected to the arc-shaped fixing sleeve 110, and the support adjustment component is used to adjust the height of the inspection component.

[0030] Specifically, in the embodiment of the utility model, the curvature inspection device 10 for the steel lining cylinder wall of the containment includes an inspection component and a support and adjustment component, wherein the arc-shaped fixing sleeve 110 has a telescopic cavity 111 extending along its bending direction. The arc-shaped fixing sleeve 110 is used to provide a stable reference point, so that the arc-shaped telescopic plate 120 can be stored and extended on its basis, so as to match the steel lining cylinder wall of a larger size to be tested, and fit closely to the curvature of the steel lining cylinder wall. The arc-shaped telescopic plate 120 has the same curvature as the arc-shaped fixing sleeve 110, and can be extended or retracted from the telescopic opening 112 to the telescopic cavity 111 by being movably arranged in the telescopic cavity 111. It is used to cooperate with the arc-shaped fixing sleeve 110 to inspect the steel lining cylinder wall of a larger size, so as to facilitate the inspection personnel to perform curvature inspection on the steel lining cylinder wall. The support and adjustment component is connected to the arc-shaped fixing sleeve 110 and is used to adjust the height of the inspection component. It is convenient for inspectors to inspect the middle part of the steel lining cylinder wall plate or other positions that are difficult to measure on the operating platform, greatly reducing the risk of inspectors working at heights and the risk of measuring tools falling at heights, and improving the efficiency of inspection and acceptance. In other embodiments, the height adjustment can be achieved through an electric or hydraulic system.

[0031] The utility model provides a device 10 for checking the curvature of a steel lining cylinder wall of a containment shell, which is provided with an arc-shaped fixed sleeve 110 and at least one arc-shaped telescopic plate 120, wherein the curvature of the arc-shaped telescopic plate 120 is the same as the curvature of the arc-shaped fixed sleeve 110, so as to ensure matching with the curvature of the steel lining cylinder wall to be checked, thereby improving the inspection accuracy of the inspection device. The arc-shaped fixed sleeve 110 is provided with a telescopic cavity 111 extending along its bending direction, and the telescopic cavity 111 is provided with a telescopic opening 112 at least at one end along the bending direction of the arc-shaped fixed sleeve 110, and the arc-shaped telescopic plate 120 can be movably arranged in the telescopic cavity 111, extending from the telescopic opening 112 or retracting into the telescopic cavity 111, thereby reducing the size of the inspection equipment, facilitating the inspection of the curvature of the steel lining cylinder wall by the inspectors, and improving the applicability and flexibility of the inspection device. At the same time, by adjusting the support adjustment component, the close fit between the arc-shaped fixing sleeve 110 and the steel lining cylinder wall panel to be inspected can be ensured, providing stable support and adjustment functions. The support adjustment component can adjust the height of the arc-shaped fixing sleeve 110 to ensure a close fit with the steel lining cylinder wall panel, so that the inspection device is no longer limited to the measurement height, greatly reducing the risk of inspectors working at heights and the risk of measuring tools falling from heights, thereby improving the acceptance efficiency of inspectors.

[0032] Reference Figures 1 to 3 In one embodiment, it also includes a telescopic adjustment component, which includes an adjustment gear 130 and a monorail gear disc 140. The adjustment gear 130 is arranged on the arc-shaped fixed sleeve 110, and the monorail gear disc 140 is arranged on the arc-shaped telescopic plate 120. The arc-shaped telescopic plate 120 is driven by the meshing of the adjustment gear 130 and the monorail gear disc 140 to extend from the telescopic opening 112 or retract into the telescopic cavity 111. In this embodiment, the telescopic adjustment component can be operated manually or electrically. When the curvature inspection device needs to be adjusted, the operator can rotate the adjustment gear 130 to mesh with the monorail gear disc 140 and drive the arc-shaped telescopic plate 120 to perform telescopic adjustment. According to the length of the steel lining cylinder wall plate to be measured, the elongation of the arc-shaped telescopic plate 120 is adjusted to achieve the curvature matching before the curvature measurement. In order to ensure the accuracy and stability of the telescopic adjustment component, it is necessary to carry out fine design and manufacturing, including the processing accuracy of the gears, the sealing and durability of the transmission device, etc. Of course, in other embodiments, the arc-shaped telescopic plate 120 may also be directly pulled manually to be telescopically retracted into the telescopic cavity 111 .

[0033] Reference Figure 2In one embodiment, the monorail gear plate 140 is arranged in an arc shape, and the curvature of the monorail gear plate 140 is consistent with the curvature of the arc-shaped telescopic plate 120. By designing the monorail gear plate 140 to be consistent with the curvature of the arc-shaped telescopic plate 120, it can be ensured that when the telescopic plate is extended or retracted, the meshing transmission between the gear and the gear plate always remains stable and smooth. This improves the operating accuracy and reliability of the device, and at the same time, reduces the friction or jamming problems caused by the mismatch between the gear and the gear plate. By making the curvature of the monorail gear plate 140 consistent with the arc-shaped telescopic plate 120, it can be ensured that the extension direction of the arc-shaped telescopic plate 120 is consistent with the arc-shaped fixed plate in the middle along the circumference direction, ensuring the accuracy and precision of the device during the curvature inspection process.

[0034] Reference Figure 1 and Figure 3 In one embodiment, an adjustment hole 113 is provided on the outer wall of the arc-shaped fixing sleeve 110 near one end of the telescopic opening 112, and the telescopic adjustment assembly includes a connecting shaft 150 and an adjustment handle 160. The adjustment handle 160 is arranged on the outer side of the arc-shaped fixing sleeve 110, and one end of the connecting shaft 150 is connected to the adjustment gear 130, and the other end passes through the adjustment hole 113 and is connected to the adjustment handle 160. In this way, the inspector can control the movement of the connecting shaft 150 by rotating the adjustment handle 160, thereby realizing the control of the adjustment gear 130. When the adjustment handle 160 rotates, the connecting shaft 150 will rotate accordingly, so that the arc-shaped telescopic plate 120 can be extended or retracted through the meshing transmission of the adjustment gear 130 and the monorail gear disk 140. The setting of the adjustment hole 113 enables the connecting shaft 150 to pass through the arc-shaped fixing sleeve 110 and be connected to the adjustment handle 160. In this embodiment, by providing an adjustment hole 113 on the arc-shaped fixing sleeve 110 and by combining the connecting shaft 150 and the adjustment handle 160 , the control and operation of the telescopic adjustment component can be facilitated, thereby improving the convenience of operation.

[0035] Reference Figure 1 and Figure 3 In one embodiment, the curvature of the outer edge of the arc-shaped telescopic plate 120 after extending out of the telescopic cavity 111 is the same as the curvature of the outer edge of the arc-shaped fixing sleeve 110. Setting the outer edge curvature of the arc-shaped telescopic plate 120 to be the same as the outer edge curvature of the arc-shaped fixing sleeve 110 helps to improve the fit of the inspection assembly to the wall surface of the steel lining cylinder wall plate when it is fitted, and ensures the reliability of the inspection device.

[0036] Reference Figure 1In one embodiment, the support adjustment assembly includes a telescopic structure and a support structure, the telescopic structure includes a hand-held rod 170, at least one telescopic rod 180 and a stopper 190, the telescopic rod 180 is telescopically arranged inside the hand-held rod 170, the stopper 190 is connected between the hand-held rod 170 and the telescopic rod 180 to limit the movable position of the hand-held rod 170 and the telescopic rod 180, and the support structure is connected to the end of the telescopic rod 180 that is away from the hand-held rod 170 after extension. It can be understood that the hand-held rod 170 is used to provide a grip for the inspector, and the telescopic rod 180 is used to adjust the inspection height of the inspection assembly, and the stopper 190 is used to limit the hand-held rod 170 and the telescopic rod 180 after the telescopic rod 180 is extended to a suitable height, so as to facilitate the inspector to perform curvature inspection.

[0037] In this embodiment, the hand-held rod 170, the telescopic rod 180 and the limiter 190 are combined to achieve flexible adjustment of the support height and stable support. The limiter 190 can be a bolt, a screw or a spring buckle, etc., which can be set as needed. Optionally, the number and length of the telescopic rod 180 can be set according to the specific scene, and are not specifically limited here.

[0038] Reference Figure 1 In one embodiment, the support structure includes a support frame 200, a base 210 and a fixing member 220, the base 210 connects the end of the telescopic structure, the support frame 200 is connected between the base 210 and the arc-shaped fixing sleeve 110, and the fixing member 220 connects the base 210 and the support frame 200. It can be understood that the role of the base 210 is to connect the end of the telescopic structure and provide an interface to connect the support frame 200. The support frame 200 can be connected to the telescopic structure through the base 210 to form a whole. The support frame 200 is connected between the base 210 and the arc-shaped fixing sleeve 110. The support frame 200 usually has strength and stability and can provide a stable supporting force. The fixing member 220 is connected between the base 210 and the support frame 200 to play a role of fixing and stabilizing. The fixing member 220 usually uses bolts, nuts or other fastening devices to connect the base 210 and the support frame 200 together to ensure the stability and reliability of the support structure. In this embodiment, the combination of the holder 210, the support frame 200 and the fixing member 220 enables the inspection component to be connected to the telescopic structure and provide a stable support force. At the same time, the holder 210 can be hinged with the support frame 200 through the fixing member 220 to achieve angle adjustment between the telescopic structure and the inspection component, thereby increasing the applicability of the inspection device. Optionally, the support frame 200 is arranged in a V-shape or a U-shape.

[0039] Reference Figure 4In one embodiment, the curvature inspection device 10 for the steel lining cylinder wall panel of the containment further includes a feeler gauge 230, and the feeler gauge 230 is used to cooperate with the inspection component to measure the curvature deviation of the steel lining cylinder wall panel. It can be understood that when performing a curvature inspection, the inspection component is placed on the steel lining cylinder wall panel, and the fit between the inspection component and the steel lining cylinder wall panel is checked by the feeler gauge 230. In this way, by performing multiple measurements at different positions, the curvature deviation of the steel lining cylinder wall panel can be obtained. According to the measurement results, it can be determined whether the steel lining cylinder wall panel meets the required curvature standard, and corresponding adjustment or correction measures can be taken. This embodiment adds a feeler gauge 230 to play an auxiliary role in the curvature inspection of the steel lining cylinder wall panel, making the measurement process more accurate and reliable.

The telescopic cavity 111 is provided with telescopic openings 112 at both ends along the bending direction of the arc-shaped fixed sleeve 110. The two arc-shaped telescopic plates 120 extend or retract from different telescopic openings 112 to the telescopic cavity 111. In this way, the inspection range of the inspection component can be increased, and the inspection efficiency and inspection accuracy of the inspectors can be improved.
