In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0048] The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings.

[0049] The embodiment of the present application provides a flatness detection tool for the installation surface of a ship sea valve, thereby solving the technical problems in the prior art that the flatness detection operation for the installation surface of a ship sea valve requires manual lifting by multiple persons, which is difficult to operate, inefficient, labor-intensive, and has low measurement accuracy.

[0050] In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0051] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a flatness detection tool for the installation surface of a ship sea valve, which can be stably assembled to the installation cavity area of ​​the ship sea valve, facilitates efficient flatness detection, improves detection accuracy, and reduces the labor intensity of detection operations.

[0052] Specifically, it includes: a flatness detection component 10 , a support component 30 and a suspension component 20 .

[0053] The flatness detection piece 10 is used as a detection piece to be fixed to the installation area of ​​the ship's sea valve, and a standard detection plane is set on the flatness detection piece 10 to abut against the installation surface of the ship's sea valve, so as to form a gap by comparison to quantitatively characterize the flatness, which can be detected by detection tools such as feeler gauges.

[0054] The support member 30 is fixed on the flatness detection member 10 as a support structure of the flatness detection member 10, and in order to stably set the flatness detection member 10, a clamping member for pressing against the installation surface of the ship sea valve is provided on the support member 30.

[0055] The hanging member 20 is connected to the supporting member 30, and a hanging supporting portion for being placed on the inner side of the installation hole of the ship sea valve is provided on the hanging member 20.

[0056] That is to say, the suspension member 20 is placed on the edge of the installation hole of the ship sea valve through the suspension support part, so that the support member 30 is suspended below the installation surface of the ship sea valve without the need for manual lifting by multiple people, thereby being able to keep the flatness detection member 10 stably against the installation surface of the ship sea valve, thereby achieving high-precision and high-reliability measurement.

[0057] In order to reduce the weight and specifications of the tooling, the flatness detection member 10 is set as a hollow detection cylinder, and the standard detection plane is set on the first axial end face of the detection cylinder. The possibility of axial fluctuation is reduced by the cylindrical body, the stability of the flatness of the circular standard detection plane is ensured, and the reliability of the detection is improved. It is worth noting that in the axial length direction of the detection cylinder, the length can be as small as possible while ensuring the anti-deformation performance of the axial shape, reducing the overall structural scale.

[0058] In order to adapt to the cylindrical structure of the detection cylinder, the support member includes: a support frame and a fastener; the support frame is arranged in the detection cylinder; the fastener is connected to the support frame, and the fastener is fixed to the fastening structure arranged on the inner wall of the detection cylinder. Thus, the axial deformation resistance of the cylindrical member is relied on to ensure uniform force on the standard detection plane.

[0059] In order to adapt to the shape of the inner wall of the cylinder, the fastener includes: a bent angle piece 40 and a fastening bolt. The bent angle piece 40 includes: an integrally formed welding bottom plate and a screw-connected vertical plate; the welding bottom plate is welded to the support frame; a fixing hole 41 is provided on the welding vertical plate, and a fastening screw hole 11 is provided on the inner wall of the detection cylinder. The fastening bolt is embedded in the fixing hole 41 and screwed into the fastening screw hole 11, so that the uniformity of the force applied by the fastening bolt can be ensured by screwing the vertical plate.

[0060] In order to ensure the reliability and stability of the fastening state of the screwed vertical plate and the fastening bolts, the screwed vertical plate is configured as an arc-shaped plate matching the inner wall of the detection cylinder, and the arc-shaped plate abuts against the inner wall of the detection cylinder.

[0061] In order to simplify the structure and ensure the reliability of the support, the support frame adopts a first support rod and a second support rod that are cross-connected; the bent angle pieces 40 are welded to both ends of the first support rod and the second support rod.

[0062] The cross structure can ensure structural strength while providing four stable fixed structures to achieve stable support.

[0063] The intersection area of ​​the first support rod and the second support rod is provided with a first connection screw hole 31, and a connection bolt is provided in the first connection screw hole 31, and the connection bolt is screwed on the suspension member 20. Thus, the connection bolt can be used to realize convenient disassembly and assembly, and is convenient for fixing to the detection site.

[0064] In order to facilitate the bending angle pieces 40 on the two support rods to be inserted into the cylindrical structure for installation, the first support rod and the second support rod can be fixedly formed and installed as one body, while ensuring the stability of the force.

[0065] Of course, in order to simplify the assembly operation, the first support rod and the second support rod are arranged close to the outside of the second axial end face of the detection cylinder. Generally, the first support rod and the second support rod can be controlled by machining accuracy so that they abut against the second axial end face of the detection cylinder, thereby simultaneously fixing the first support rod and the second support rod to the inner wall and the second axial end face of the detection cylinder in stable contact, ensuring the stability of the force on the detection cylinder and the stability of its posture, thereby improving the detection accuracy.

[0066] Correspondingly, the ends of the first support rod and the second support rod are both provided with the clamping members to achieve four-end point fixation.

[0067] See also Figure 4 and Figure 5 In order to facilitate the positioning of the standard detection plane on the detection cylinder, adjustment screw holes 32 are provided at the ends of the first support rod and the second support rod.

[0068] The clamping member includes: a clamping bolt; the clamping bolt is threaded in the adjusting screw hole, so that by rotating the clamping bolt, the clamping bolt can be pressed against the installation surface of the ship sea valve, so that it can be pressed against the standard detection plane in a stable posture.

[0069] See also Figure 3 The hanging member 20 includes: a cross support frame; a second connecting screw hole 21 is opened on the cross support frame, and the connecting bolt is screwed into the second connecting screw hole 21, so that the supporting frame can be conveniently disassembled and assembled on the cross support frame, thereby enabling efficient on-site disassembly and assembly.

[0070] This embodiment also provides a flatness detection method based on the flatness detection tool for the installation surface of the ship sea valve, and performs the following steps:

[0071] Pass the hanging member 20 through the installation hole of the ship's sea valve, and place it on the inner wall of the ship's main body based on the hanging support part;
