Technical Field

[0002] A boiler is an energy conversion device used to convert input energy such as chemical energy and electrical energy in fuel into steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The boiler is mainly composed of two parts: the "pot" and the "furnace". The "pot" is a pressurized component that holds water and steam, and heats, vaporizes and separates the water; the "furnace" is a place where fuel combustion or other heat release is carried out, and it has combustion equipment, a combustion chamber, a furnace and a heat release flue.

[0003] During the manufacturing process of the boiler, it is necessary to monitor and test the stress strength of its external pressure-bearing components to ensure that the boiler has a certain stress and pressure resistance during use. However, some monitoring devices on the market currently only have monitoring devices and are unable to perform stress testing on them regularly. As a result, as the use time increases, the stress strength caused by the aging of parts decreases, and its value cannot be tested more directly. Therefore, a stress strength monitoring device for the external pressure-bearing components of the boiler is proposed. Utility Model Content

[0030] In this example, see Figure 1 and Figure 2 The utility model provides a technical solution: it includes a construction platform 1 and a supporting leg 2, and the supporting leg 2 is fixedly installed on the lower end surface of the construction platform 1, and a placing platform 3 is fixedly provided in the middle of the upper end surface of the construction platform 1. In addition, fixed plates 4 are fixedly installed on the left and right sides of the upper end surface of the construction platform 1, and support columns 5 are fixedly provided on the front and rear end surfaces of the fixed plates 4, and a protection box 7 is fixedly installed on the upper end surface of the support column 5. Furthermore, a driving motor 8 is provided in the middle of the upper end surface of the protection box 7, and a first connecting disk 81 is installed on the output end of the driving motor 8;

[0031] Among them, the construction platform 1 is used as the main body of the device to provide support for the components above. At the same time, the placement platform 3 above the construction platform 1 is used to place pressure-bearing components that need to be tested for stress strength. The support legs 2 are used to provide stable support for the construction platform 1. The number of support legs 2 can be increased in groups according to the weight above. The fixed plate 4 is used to provide a limiting and stable function for the lower end of the connecting plate 93. The support column 5 is used to provide support for the support plate 6 and the protection box 7. The connection method between the construction platform 1, the support legs 2, the placement platform 3, the fixed plate 4, the support column 5, the support plate 6 and the protection box 7 can all be fixedly connected and installed using existing methods. The drive motor 8 is an existing drive motor, which is connected to the protection box 7 and the first connecting plate 81 using the existing installation method.

[0032] For further information, see Figure 1 、 Figure 2 and Figure 3 The transmission assembly is composed of a second connecting disk 91, a connecting rod 92, a connecting plate 93 and a mounting plate 94. The second connecting disk 91 is respectively arranged on the left and right sides of the first connecting disk 81. In addition, the connecting rod 92 is fixedly mounted on the lower end surface of the second connecting disk 91, and the lower end of the connecting rod 92 is rotatably connected to the fixed plate 4. Furthermore, the connecting plate 93 is arranged on the outer side of the middle part of the connecting rod 92 and is connected to the support column 5. The mounting plate 94 is fixedly mounted on the inner side of the connecting plate 93.

[0033] Among them, the second connecting disk 91 is symmetrically arranged in two groups based on the vertical center axis of the first connecting disk 81. At the same time, the second connecting disk 91 is engaged with the first connecting disk 81, so that the first connecting disk 81 can drive the second connecting disk 91 to rotate synchronously through the driving motor 8. The second connecting disk 91 and the connecting rod 92 form an integrated structure, so that the second connecting disk 91 can drive the connecting rod 92 to rotate synchronously. The connecting rod 92 is externally threaded with the connecting plate 93, and the connecting plate 93 is slidingly connected to the support column 5. When the connecting rod 92 rotates, the connecting plate 93 can move up and down through the limit of the support column 5, thereby driving the mounting plate 94 to move.

[0034] For further information, see Figure 1 A stress strength detector 10 is installed in the middle of the upper end surface of the mounting plate 94, and a stress monitoring detection press needle 11 is connected to the lower end surface of the mounting plate 94. The stress strength detector 10 is an existing pressure-bearing part stress strength detector, and is installed and connected with the mounting plate 94 and the stress monitoring detection press needle 11 in an existing manner. The stress monitoring detection press needle 11 is an existing press needle used for monitoring testing.

[0035] Working principle: First, the construction platform 1 is stably placed in the designated position through the support legs 2, and then the pressure-bearing parts that need to be monitored and inspected are placed on top of the placement platform 3. Then, the drive motor 8 is turned on to drive the first connecting disk 81 to rotate, so that the first connecting disk 81 drives the connecting rod 92 to rotate through the second connecting disk 91, and then the connecting plate 93 drives the mounting plate 94 to move downward through the external thread connection with the connecting rod 92. After that, when the mounting plate 94 moves downward, the stress monitoring detection pressing needle 11 will apply pressure to the pressure-bearing parts below, thereby feeding back the data to the inside of the stress strength detector 10, and finally the stress strength detector 10 will present the stress intensity data of the pressure-bearing parts being monitored and inspected.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
