Description

Technical Field

[0001] The utility model relates to the technical field of medium frequency furnaces, in particular to a tool for measuring the thickness of a medium frequency furnace lining. Background Art

[0002] The medium frequency furnace is a kind of equipment used for smelting non-ferrous metals. The lining of the medium frequency furnace needs to be operated at a safe thickness. During the smelting process, long-term smelting will gradually make the thickness of the lining thinner, and even pits and holes will appear. If the thickness of any part of the inner wall is less than the safe thickness, it will easily penetrate and cause a safety accident. Therefore, after the medium frequency furnace has been working for a period of time, the lining thickness of the medium frequency furnace needs to be measured to prevent the occurrence of safety accidents.

[0003] In the prior art, a worker holds a scissor-shaped measuring device, continuously touches the two ends of the measuring device to the furnace lining, and observes the changes in the measuring device to determine the thickness of the furnace lining. When the thickness of the furnace lining is measured to have changed, the worker cannot record the location of the change in time, and the subsequent repair will result in inaccurate repair positions. The entire process is relatively time-consuming. The worker judges the thickness of the furnace lining by visually observing the changes in the measuring device, which may be inaccurate and easily lead to safety accidents during use.

The electric drive method is adopted. Compared with the traditional manual method, the measurement process is smoother, and the measured data is more accurate.

[0031] like Figure 1-7 As shown, the measuring rod I7 and the measuring rod II8 are respectively arranged on both sides of the supporting plate 1, and the measuring rod I7, the measuring rod II8 are rotatably connected with the driving member. The measuring rod I7 and the measuring rod II8 rotate in opposite directions. An elastic member is also provided on the driving member, and the elastic member abuts against the measuring member.

The through slot 32 passes through the support structure and is connected to the connecting hole 31. The measuring piece passes through the through slot 32, and a hole 72 is provided in the measuring piece (measuring rod I 7, measuring rod II 8). The measuring rod I 7 passes through the through slot 32 and is provided in the support cylinder I 3. The measuring rod II 8 passes through the through slot 32 and is provided in the support cylinder II 5. The hole 72 and the connecting hole 31 are provided in the support cylinder I 3. 1 is aligned, a support plate 4 is detachably provided on the support structure, and the support plate 4 is respectively connected to the support tube I 3 and the support tube II 5 by bolts.

The connecting shaft 41 extends into the connecting hole 31. The measuring rod I 7 and the measuring rod II 8 rotate with the connecting shaft 41 as the center of the circle. The width of the through slot 32 is greater than the width of the measuring piece, so that the measuring piece can rotate a certain angle in the through slot 32. The plug-in structural design is adopted. If there is a problem with the measuring tool in the future, it is convenient for subsequent disassembly, maintenance and replacement.

[0033] like Figure 1 、 4, 5, 6, and 7, the measuring rod I7 and the measuring rod II8 are respectively arranged on both sides of the supporting plate 1, and the measuring rod I7, the measuring rod II8 are rotatably connected to the driving member, and the measuring rod I7 and the measuring rod II8 rotate in opposite directions. The driving member is also provided with an elastic member, and the elastic member abuts against the measuring member. The elastic member makes the measuring rod I7 and the measuring rod II8 continuously contact with the furnace lining B.
