[0041] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0042] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0043] Combination Figure 1 As shown, an embodiment of the present disclosure provides a circularity inspection device, which includes a bracket body 1, a top support member 2, a detection arc band 3 and an adjustment member 4; a mounting portion is formed on one side of the bracket body 1; the detection arc band 3 is adjustably arranged in the mounting portion, and the side of the band facing away from the bracket body 1 is a detection surface; the adjustment member 4 is connected to one end of the detection arc band 3; the top support member 2 is passed through the bracket body 1, and one end abuts against the top support on the side of the detection arc band 3 facing away from the detection surface; wherein the adjustment member 4 can adjust the effective length of the detection arc band 3 in the mounting portion to change the curvature of the detection surface of the detection arc band 3.

[0044] The circumference inspection device can be specifically but not limited to being used for the inspection of the circumference of pressure vessels, and the use process is explained by taking examples one by one.

[0045] When the circularity inspection device is used in practice, the effective length of the detection arc band 3 in the installation portion is first adjusted by the adjusting member 4, so that the curvature of the detection surface in the detection arc band 3 can be adapted to the curvature of the circumferential wall in the pressure vessel to be tested, and then the supporting member 2 is correspondingly abutted against the back side of the detection arc band 3 after the curvature is adjusted. In this way, the circularity inspection device can detect the curvature of the circumferential wall in the pressure vessel to be tested, and the detection only needs to abut the circumferential wall of the pressure vessel to be tested with the detection surface of the detection arc band 3, and observe whether there is a gap between the two, so as to determine whether the circularity of the circumferential wall in the pressure vessel to be tested meets the standard.

[0046] Moreover, when the circularity inspection device needs to detect the circularity of the circumferential wall in containers of different diameters and different curvatures, the actual curvature of the detection surface of the detection arc band 3 can be changed by simply increasing or decreasing the effective length of the detection arc band 3 in the mounting portion through the adjustment member 4, thereby fully ensuring the universal adaptability of the circularity inspection device.

[0047] In summary, the circularity inspection device provided by the embodiment of the present disclosure has the beneficial effects of simple structure and the ability to flexibly adapt to the detection requirements of arc surfaces with different curvatures.

[0048] In one embodiment, the adjustment member 4 is a sliding locking member arranged on one side of the bracket body 1; the sliding locking member can slide to tighten or slide to release the detection arc band 3 to adjust the effective detection length of the detection arc band 3 in the installation part.

[0049] Specific, combined Figure 3 and Figure 4 Further detailed description, the adjustment member 4 is specifically configured as a sliding locking member located on one side of the bracket body 1, so that the adjustment member 4 can tighten or loosen the detection arc band 3 by sliding back and forth along one side of the bracket body 1, thereby correspondingly realizing the function of increasing or decreasing the effective detection length of the detection arc band 3 in the installation part and changing the actual detection curvature of the detection arc band 3.

[0050] Moreover, in order to ensure that the adjustment member 4 can slide accurately and controllably on one side of the bracket body 1, a corresponding sliding guide rail can be opened in the side wall of the bracket body 1, and the adjustment member 4 and the sliding guide rail can adopt a limited self-locking sliding connection method to ensure that the adjustment member 4 can stop and lock at any position in the sliding guide rail.

[0051] The specific arrangement of the adjusting member 4 has the beneficial effects of being simple in structure and being able to detect the length and curvature of the arc belt 3 by means of linear reciprocating sliding.

[0052] In one embodiment, the adjustment member 4 is a rotating locking member arranged on one side of the bracket body 1; the rotating locking member can rotate and reel in, or rotate and reel in the detection arc belt 3 to adjust the effective detection length of the detection arc belt 3 in the installation part.

[0053] Specific, combined Figure 2 Further detailed description, the adjusting member 4 is specifically configured as a rotating locking member located on one side of the bracket body 1, so that the adjusting member 4 can realize the winding or winding of the detection arc band 3 by rotating around its own axis, thereby correspondingly realizing the function of increasing or decreasing the effective detection length of the detection arc band 3 in the installation part and changing the actual detection curvature of the detection arc band 3.

[0054] Furthermore, in order to ensure that the adjusting member 4 can rotate precisely and controllably on one side of the bracket body 1, the rotating locking member can be provided with a corresponding locking mechanism at its own rotation axis to achieve fixed locking of the dynamic locking member at any rotation angle.

[0055] In one embodiment, the top support member 2 includes a top support rod 21 and a screw member 22; the top support rod 21 is movably inserted into the bracket body 1, and a threaded structure is provided on the outer peripheral wall; the screw member 22 is movably arranged on a side of the bracket body 1 facing away from the mounting portion, and is threadedly sleeved on the outer peripheral wall of the top support rod 21;

[0056] Among them, one end of the supporting rod 21 located in the bracket body 1 is the supporting end; the screwing member 22 can be screwed to adjust the effective supporting length of the supporting rod 21 located in the bracket body 1.

[0057] Specific, combined Figure 1 To further explain in detail, the top support member 2 is specifically configured as a top support rod 21 and a screw member 22, and the outer peripheral wall of the top support rod 21 is provided with a threaded structure, the screw member 22 is movably arranged on the side of the bracket body 1 facing away from the mounting portion, and is threadedly sleeved on the outer peripheral wall of the top support rod 21, so that the top support rod 21 can be moved up and down in the insertion direction of the bracket body 1 by turning the screw member 22.

[0058] The specific arrangement of the supporting member 2 has the beneficial effects of being simple in structure and being able to flexibly and accurately adjust the effective length of the supporting member 2 in the displacement bracket body 1 .

[0059] In one possible implementation manner, the supporting rod 21 is further provided with a supporting head 211 at the supporting end; the supporting rod 21 is indirectly supported and abutted against a side of the detection arc belt 3 facing away from the detection surface through the supporting head 211 .

[0060] Specific, combined Figure 2 To further explain in detail, the width of the above-mentioned top support head 211 can be specifically 2 to 3 times the diameter of the top support rod 21, which can effectively increase the top support contact area between the top support head 211 and the detection arc band 3; and a rubber gasket can also be arranged on the side of the top support head 211 facing the detection arc band 3, which is used to increase the contact friction between the top support head 211 and the detection arc band 3, and to buffer and disperse the top support pressure between the two.

[0061] The specific arrangement of the supporting head 211 has the beneficial effects of simple structure, being able to increase the contact friction between the supporting head 211 and the detection arc belt 3, and improving the stability of the supporting contact between the two.

[0062] In one possible implementation, a plurality of supporting rods 21 are arranged at intervals in the bracket body 1 ; and each supporting rod 21 can be individually adjusted to an effective supporting length in the bracket body 1 by a corresponding screw member 22 .

[0063] Specific, combined Figure 1To further explain in detail, at this time, three support rods 21 are specifically arranged in parallel and at intervals in the bracket body 1, and the three support rods 21 can be individually adjusted by the corresponding screw parts 22 to have an effective support length in the bracket body 1, so that no matter what curvature the detection arc band 3 is adjusted to, the three support rods 21 can also effectively support the side of the detection arc band 3 that is away from the detection surface.

[0064] The specific arrangement of the supporting rod 21 has the beneficial effects of simple structure, being able to adjust its own length separately, and ensuring that it can support the detection arc belts 3 with different curvatures.

[0065] In one possible implementation, the detection arc belt 3 is an arc-shaped steel belt; and one side of the arc-shaped steel belt can be concave toward the bracket body 1 to form a detection surface, or one side of the arc-shaped steel belt can be convex facing away from the bracket body 1 to form a detection surface.

[0066] Specific, combined Figure 3 and Figure 4 To further explain in detail, the detection arc belt 3 is specifically set as an arc-shaped steel belt. The steel belt has rigidity and toughness, and can flexibly and smoothly change its own curvature as the adjustment of the adjustment part 4 is made. When one side of the arc-shaped steel belt can be recessed toward the bracket body 1 to form a detection surface, it can be used to detect the circumference of the outer wall of the tank body. When one side of the arc-shaped steel belt can be raised with its back facing the bracket body 1 to form a detection surface, it can be used to detect the circumference of the inner wall of the tank body, thereby further improving the universal adaptability of the circularity inspection device.

[0067] The specific configuration of the detection arc belt 3 has the beneficial effects of good rigidity and toughness and can further improve the universal adaptability of the detection arc belt 3.

[0068] In one possible implementation manner, the effective length of the detection arc belt 3 in the installation portion is at least 400 mm.

[0069] Specific, combined Figure 1 To further explain in detail, the effective length of the detection arc belt 3 in the installation part is limited to at least 400 mm, which can fully ensure the effective detection length of the detection arc belt 3 and ensure the circular arc detection effect of the detection arc belt 3 on the circular surface to be tested.

[0070] In one possible implementation manner, the adjusting member 4 is marked with a scale line value for displaying the curvature of the detection surface of the detection arc band 3 .

[0071] The adjusting member 4 is marked with scale line values ​​for displaying the curvature of the detection surface of the detection arc band 3. When the adjusting member 4 is adjusted accordingly, the actual detection curvature of the detection arc band 3 can be intuitively obtained by directly observing the corresponding scale line values ​​of the curvature in the adjusting member 4. There is no need to measure the detection arc band 3, which is facilitating intuitive understanding for operators and improving detection efficiency.

[0072] In one possible implementation manner, a self-locking mechanism is further provided in the adjusting member 4; the self-locking mechanism is used to self-lock the adjusting member 4 to fix the effective length of the detection arc belt 3 in the installation portion.

[0073] A self-locking mechanism is also provided in the adjusting member 4. The self-locking mechanism can be specifically but not limited to being provided as a push-type self-locking buckle, a push-type self-locking ratchet, etc. In this way, the self-locking function of the self-locking mechanism can be used to ensure that the adjusting member 4 self-locks the detection arc band 3 at any position, thereby achieving the beneficial effect of fixing the effective length of the detection arc band 3 in the installation part.

[0074] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0075] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
