Description

Technical Field

[0001] This utility model relates to the field of pressure vessel testing technology, specifically a pressure vessel corner testing ruler. Background Technology

[0002] When manufacturing and using boilers and pressure vessels, it is necessary to inspect their defects such as edges, undercuts, misalignments, corrosion depth, and diameter. Currently, there is no dedicated measuring tool for measuring the edges of these cylindrical and spherical objects of varying diameters. We can only temporarily make arc-shaped templates of varying curvatures and place them against the wall of the boiler or pressure vessel being tested for inspection. This not only brings many difficulties to the inspection work, but also wastes manpower, material resources, and time.

[0003] Chinese Patent Publication No. CN221840323U discloses a pressure vessel edge angle measuring ruler, relating to the field of pressure vessel testing technology. It includes a main ruler, an inner ruler, and side supports. The inner ruler is slidably disposed within the main ruler and extends from its end opening. The side supports include a sliding sleeve and support rods. The sliding sleeve is detachably connected to the main ruler, and two support rods are rotatably connected to both sides of the sliding sleeve. The inner ruler extends beyond one end of the main ruler and is located between the two extended support rods. This invention utilizes the two extended support rods to abut against both sides of the weld, providing a quick and convenient operation. By adjusting the readings of the inner ruler sliding out from the main ruler and abutting against the weld, as well as the readings of the edges of the weld, the pressure vessel edge angle can be obtained, resulting in accurate measurement data.

[0004] However, existing pressure vessel corner gauges have the following drawbacks: Existing pressure vessel corner measuring rulers can only measure the height of corners and welds, but cannot measure the base length of welds and corners. The application scenarios of existing pressure vessel corner measuring rulers are relatively limited, and their functionality is relatively simple, making it difficult to measure other objects. Utility Model Content

[0005] (a) Technical problems to be solved To overcome the aforementioned shortcomings of the prior art, this utility model provides a pressure vessel corner measuring ruler, which solves the problems in the prior art: Pressure vessel edge and corner inspection gauges are difficult to use for measuring edges, corners, and welds, and their application scenarios are limited.

[0006] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a pressure vessel edge detection ruler, including a main ruler, a sliding sleeve fitted at one end of the main ruler, a cavity left inside the sliding sleeve, auxiliary rulers provided on both sides of the main ruler and slidably connected to the inside of the sliding sleeve, and positioning rulers provided at both ends of the sliding sleeve.

[0007] Optionally, both ends of the sliding sleeve are provided with sliding grooves, and the sliding sleeve and the positioning ruler are slidably connected through the sliding grooves.

[0008] Optionally, a protractor is fixedly installed on one side of the top of the main scale.

[0009] Optionally, a protractor is provided on the top of the main scale, which can be used in conjunction with a protractor to measure angles.

[0010] Optionally, a rotating screw is provided on the top of the main ruler, which rotates to connect the main ruler to the protractor.

[0011] Optionally, a friction sleeve is provided at the bottom end of the main scale.

[0012] Optionally, a measuring scale is provided below the main scale, which can be contracted and extended through a friction sliding sleeve.

[0013] Optionally, an extension plate is fixedly installed at the bottom of the measuring ruler to better fit the edges and corners for measurement.

[0014] (III) Beneficial Effects This utility model provides a pressure vessel corner measuring ruler, which has the following beneficial effects: This pressure vessel edge and corner measuring ruler consists of a main scale and a sliding sleeve. A cavity is provided inside the sliding sleeve, and a secondary scale is inserted into the cavity between the lower end of the main scale and the sliding sleeve. The secondary scale can slide laterally within the sliding sleeve to measure the width of welds and edges. Sliding grooves are provided at both ends of the sliding sleeve, through which the positioning ruler is slidably connected to the sliding sleeve. The extension length can be adjusted without sacrificing accuracy to accommodate various environments. A protractor is fixedly installed on one side of the main scale, which can cooperate with a protractor fixed to the upper end of the main scale by rotating screws to measure object angles, etc. A measuring ruler is inserted into the bottom of the main scale via a friction sliding sleeve, allowing for retraction and extension. An extension plate is fixedly installed at the bottom of the measuring ruler, increasing the fit between the measuring ruler and the weld and edges during measurement, thus improving measurement accuracy.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a pressure vessel corner detection ruler, including a main ruler 1, a sliding sleeve 2 sleeved at one end of the main ruler 1, a cavity left inside the sliding sleeve 2, auxiliary rulers 3 are provided on both sides of the main ruler 1 and are slidably connected to the inside of the sliding sleeve 2, and positioning rulers 4 are provided at both ends of the sliding sleeve 2.

[0019] Both ends of the sliding sleeve 2 are provided with sliding grooves 5. The sliding sleeve 2 and the positioning ruler 4 are slidably connected through the sliding grooves 5. The position of the positioning ruler 4 can be adjusted through the sliding grooves 5.

[0020] A protractor 6 is fixedly installed on one side of the top of the main ruler 1. The installation of the protractor 6 solves the problem of the single application scenario of the pressure vessel corner inspection ruler.

[0021] A protractor 7 is provided on the top of the main ruler 1. The protractor 7 can be used with the protractor 6 to measure angles. Conventional measurements can be performed by adding the protractor 7.

[0022] The main ruler 1 is equipped with a rotating screw 8 at its top. The rotating screw 8 connects the main ruler 1 to the protractor 7 by rotation. The installation of the rotating screw 8 increases the rotatability of the protractor 7, making it more suitable for various complex scenarios.

[0023] The bottom end of the main scale 1 is provided with a friction sleeve 9, which allows the measuring scale 10 to extend and retract.

[0024] A measuring scale 10 is provided below the main scale 1. It can be extended and retracted by the friction sleeve 9. Extending and retracting the measuring scale 10 by the friction sleeve 9 can more accurately measure the height of the edge.

[0025] An extension plate 11 is fixedly installed at the bottom of the measuring ruler 10, which can better fit the corners for measurement. By adding the extension plate 11, the bottom surface can be more accurately fitted to the corners.

[0026] In this invention, the working steps of the device are as follows: Hold the upper part of the main scale firmly, adjust the positioning scales and vernier scales at both ends of the sliding sleeve to the same plane, extend the measuring scale to its longest position, slowly bring the extension plate at the bottom of the measuring scale close to the apex of the weld and the edge, and then slowly push the vernier scales on both sides of the main scale inward until they are close to the edge of the weld and the edge. Make sure that the apex of the vernier scale is close to the edge of the edge being measured, and that the bottom surface of the measuring scale is in contact with the top surface of the edge being measured. Then you can take it out and read the value.
