The top surface of the distance sensor 19 is flush with the top surface of the measuring table 1 and is vertically corresponding to the magnet 16. The distance sensor 19 is electrically connected to the controller 11.
[0015] When detecting the curvature of the furnace column, the furnace column to be measured can be first placed on the measuring table 1, with one end thereof located below the magnetorheological pressing plate 8 corresponding to the first hydraulic cylinder 4. Then, the first hydraulic cylinder 4 is operated to extend its piston rod, which can drive the corresponding magnetorheological pressing plate 8 to move downward until it presses against one end of the furnace column, and the one end of the furnace column is firmly pressed and fixed by the magnetorheological pressing plate 8. Then, the second hydraulic cylinder 5 is operated to extend its piston rod, driving the movable plate 6 to move towards the direction where the first hydraulic cylinder 4 is located until the magnetorheological pressing plate 8 corresponding to the third hydraulic cylinder 7 is located at the other end of the furnace column. Next, the third hydraulic cylinder 7 is operated to extend its piston rod, which can drive the corresponding magnetorheological pressing plate 8 to move downward until it presses against the other end of the furnace column, and the other end of the furnace column is also pressed and fixed, thus completing the firm pressing and fixing of the furnace column. After that, a measuring position is selected on the furnace column, and the first electric slider 13 is operated to drive the measuring plate 15 to move above the selected measuring position. Then, the fourth hydraulic cylinder 14 is operated to extend its piston rod, which can drive the measuring plate 15 to move downward until the measuring plate 15 presses against the top surface of the furnace column. Then, the second electric slider 18 is operated to drive the distance sensor 19 to move below the measuring plate 15, and the distance between the distance sensor 19 and the magnet 16 can be detected and the information is fed back to the controller 11. Next, according to the foregoing operations, multiple measuring positions are selected and the corresponding distances are measured respectively, and finally the curvature of the furnace column can be calculated. In this way, the multi-point automatic and precise measurement of the curvature of the furnace column can be realized, the operation is simple and convenient, more time-saving and labor-saving and precise, and more convenient and practical. The controller 11 can adopt the existing technology.
[0016] In this embodiment, the magnetorheological pressing plate 8 includes a substrate 20 fixedly connected to the piston rod of the corresponding first hydraulic cylinder 4 or the third hydraulic cylinder 7. An electromagnetic coil 21 is embedded on the peripheral side of the substrate 20, and a pressure sensor 22 is embedded at one end of the substrate 20 away from the corresponding first hydraulic cylinder 4 or the third hydraulic cylinder 7. The peripheral side of the substrate 20 and the side thereof away from the corresponding first hydraulic cylinder 4 or the third hydraulic cylinder 7 are wrapped with a magnetorheological elastomer 23. The tail end of the pressure sensor 22 extends into the corresponding magnetorheological elastomer 23. Both the electromagnetic coil 21 and the pressure sensor 22 are electrically connected to the controller 11. When pressing and fixing the furnace column, in the initial state, the electromagnetic coil 21 is not energized, and the magnetorheological elastomer 23 is in a pre-yield state with a small shear yield stress and is prone to deformation. When the magnetorheological pressing plate 8 contacts the end of the corresponding furnace column, it can reduce the impact generated by the contact and ensure stability. Then, when the magnetorheological pressing plate 8 continues to move downward, the magnetorheological elastomer 23 can continue to press against the furnace column. At this time, the magnetorheological elastomer 23 is deformed under pressure and can thus perfectly nest and wrap around the furnace column. At the same time, the pressure sensor 22 is pressed and gives an electrical signal to the controller 11, enabling the controller 11 to determine through the pressure sensor 22 that the magnetorheological elastomer 23 has been deformed by pressing against the furnace column, and thus automatically control the circuit of the electromagnetic coil 21 to be turned on. The electromagnetic coil 21 is energized to generate a magnetic field, and the magnetorheological elastomer 23 can generate a large shear yield stress in the magnetic field environment, causing its shape to solidify and no longer change. Furthermore, it can perfectly fit the surface of the furnace column, firmly press and fix the furnace column on the measuring table, making the fixation more stable and reliable, not affecting subsequent measurement operations, and ensuring the measurement quality. When the furnace column is removed after the measurement is completed, only the piston rod of the corresponding hydraulic cylinder needs to be contracted to drive the magnetorheological pressing plate 8 to move upward. During this process, the pressure sensor 22 loses pressure and gives an electrical signal to the controller 11 again, enabling the controller 11 to automatically control the circuit of the electromagnetic coil 21 to be disconnected. As a result, the magnetorheological elastomer 23 returns to its original state after losing the magnetic field effect, thus not affecting its subsequent pressing use. The use of the entire measuring device can flexibly adapt to the pressing and fixing of furnace columns of different specifications, improving the pressing stability of the furnace column while further enhancing the flexibility and convenience of the device. The electromagnetic coil 21 and the pressure sensor 22 can both adopt existing technologies. The magnetorheological elastomer 23 is an existing technology. Micron-scale ferromagnetic particles are incorporated into a polymer matrix. It can deform and recover in a normal environment and can be solidified in a magnetic field environment. Therefore, the particles in the matrix have a chain or columnar structure. The elastic modulus of this material can vary with the applied magnetic field strength. Thus, it is expected to be widely used in variable stiffness devices and other aspects. Compared with ordinary magnetorheological fluids, the magnetorheological elastomer not only has high-tech characteristics such as controllability, reversibility, and rapid response but also has unique advantages such as good stability.
[0017] In this embodiment, the measuring table 12 is made of aluminum foam. Aluminum foam is an existing material with excellent properties such as high specific stiffness, high damping shock absorption, high impact energy absorption rate, corrosion resistance, and heat resistance. The measuring table 1 is made of this material, which is more conducive to ensuring the smooth progress of the measurement operation.
[0018] In this embodiment, a rubber anti-slip pad 24 is fixedly installed at the bottom of the measuring table 1, which can effectively enhance the friction between the measuring table 1 and the ground, make the entire measuring device placed more stably and reliably, and ensure the smooth progress of the measurement operation.
[0019] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
