[0002] In the workshop production process, head inspection is an important link to ensure the quality and safety of pressure vessels. At present, the head inspection sample commonly used in the workshop is a whole plate sample made according to the standard. This sample performs well in the inspection of small diameter heads, is easy to operate and can effectively evaluate the shape and size deviation of the head.

[0003] However, as the diameter of the head increases, especially when the head diameter exceeds 2000mm, the traditional whole plate sample exposes obvious limitations. First, the weight of the large-sized whole plate sample increases significantly, which is not only difficult to carry, but also inconvenient to operate during the inspection process, which seriously affects the inspection efficiency. Secondly, when the whole plate sample is placed inside the large-diameter head, it is difficult to accurately control its verticality with the inspection surface, which may lead to measurement errors and affect the accuracy of the data.

[0004] In addition, according to the standard requirements, the center of the head needs to be repositioned when repeated measurements are made. This process is particularly complicated in the detection of large-diameter heads and is prone to measurement deviations. At the same time, the traditional whole-plate template has a single function and lacks flexibility in the detection of heads of different diameters. When inspecting small-diameter heads, one person can complete the work, but for the inspection of large-diameter heads, three people are required to collaborate, which undoubtedly increases the consumption of manpower and material resources.

[0007] Preferably, the positioning seat is made of angle steel material and has an L-shaped cross-section.

[0008] Preferably, the locking device comprises a locking bolt, the end of which passes through the positioning seat and is locked and fixed by a positioning nut.

[0009] Preferably, the horizontal length of the inspection template is smaller than the length of the positioning seat and includes a plurality of different sizes.

[0010] Preferably, the bottom of the positioning nut is welded and fixed in the middle of the top horizontal plane of the inspection sample, and the threaded end of the locking bolt is connected to the internal thread of the positioning nut.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides an elliptical head inspection device, such as Figure 1-Figure 5 As shown, it includes an inspection template 2, which is a hollow structure, with a downwardly protruding arc surface at the bottom and a flat top. A positioning seat 1 is arranged on the top of the inspection template 2, and the middle part of the positioning seat 1 is connected to the middle of the top of the inspection template 2 through a locking device 6. A horizontal positioning gasket 3 is arranged between the bottom of the positioning seat 1 and the top horizontal section of the inspection template 2. When the locking device 6 is released, the inspection template 2 can rotate around the middle part of the positioning seat 1 to repeat the measurement of the shape and size deviation of the head at different positions.

[0024] In this embodiment, the positioning seat 1 is made of angle steel material and has an L-shaped cross section.

[0025] Specifically, the locking device 6 includes a locking bolt 4, the end of which passes through the positioning seat 1 and is locked and fixed by a positioning nut 5 to ensure that the inspection sample 2 is fixed horizontally.

[0026] Furthermore, the horizontal length of the inspection template 2 is smaller than the length of the positioning seat 1, and includes a plurality of different sizes, so as to realize the inspection of a plurality of heads of different sizes.

[0027] Furthermore, the bottom of the positioning nut 5 is welded and fixed in the middle of the top horizontal plane of the inspection sample 2, and the threaded end of the locking bolt 4 is connected to the internal thread of the positioning nut 5 to ensure that the inspection sample 2 is locked and fixed.

[0028] Furthermore, the diameter of the horizontal positioning washer 3 is the same as the bottom width of the positioning seat 1 , so as to cushion the bottom of the positioning seat 1 and avoid wear.

[0029] Furthermore, a washer groove 21 is provided in the middle of the top of the inspection sample 2, and the horizontal positioning washer 3 is located inside the washer groove 21, which is convenient for the installation of the horizontal positioning washer 3.

[0030] When the elliptical head inspection device of the utility model is used, the inspection sample 2 is first placed inside the elliptical head to be inspected, ensuring that the bottom arc surface of the sample is tightly fitted with the inner surface of the head. Subsequently, the inspection sample 2 is firmly fixed inside the head through the positioning seat 1 and the locking device 6. The two ends of the positioning seat 1 are placed outside the opening of the elliptical head. The positioning seat 1 is made of angle steel material and has sufficient strength and stability. The locking device 6 includes a locking bolt 4 and a positioning nut 5. By tightening the locking bolt 4, it passes through the positioning seat 1 and is tightly connected with the positioning nut 5, so that the inspection sample 2 is firmly locked inside the head.

[0031] In the locked state, the shape and size deviation of the head can be preliminarily determined by observing the fit between the inspection sample 2 and the inner surface of the head. In order to make more accurate measurements, the locking device 6 can be loosened to allow the inspection sample 2 to rotate around the middle of the positioning seat 1. During the rotation process, the shape and size deviation of the head at different positions can be repeatedly measured to obtain more comprehensive data.

[0032] In addition, the horizontal length of the inspection sample 2 is smaller than the length of the positioning seat 1, which allows the sample to move and rotate freely on the positioning seat 1, facilitating multi-point measurement. At the same time, the device also includes a plurality of inspection samples 2 of different sizes to meet the inspection requirements of elliptical heads of different sizes.
