Description

Technical Field

[0001] This invention belongs to the field of tin bath technology in glass production, and particularly relates to a support device and method for assisting in detecting the torque of the fixing studs of the bottom brick of the tin bath. Background Technology

[0002] Float glass technology is currently the most widely used and highest-capacity glass production technology. The tin bath, as a key thermal equipment in float glass technology, plays an important role in glass forming: in a production environment with protective gas, molten glass floats on the surface of molten tin in the tin bath, and spreads and flattens on the surface of molten tin to form a glass ribbon with uniform thickness and a smooth surface. The formed glass ribbon then enters the annealing furnace, and after annealing, cutting and other processes, the final glass product is obtained.

[0003] In the float glass manufacturing process, a tin bath is used to hold molten tin, such as... Figure 1 As shown, it is usually a tank-type structure formed by refractory tin bath bottom bricks 1 lined with tin bath steel shell 2. In order to prevent the tin bath bottom bricks from floating by molten tin, the tin bath bottom bricks 1 are generally provided with stepped holes that run vertically through each other. The stepped holes include bottom brick fixing holes 1-1 located below the tin bath bottom bricks 1. Fixing studs 3 welded to the bottom plate of the tin bath steel shell 2 extend upward through the bottom brick fixing holes 1-1. Then, washers are directly put on the extended fixing studs 3 and nuts are tightened. Thus, the tin bath bottom bricks 1 are fixed to the tin bath steel shell 2 by fixing studs 3. For the above installation method of the tin bath bottom brick, the molten tin flowing downward from the tin bath during the glass production process will inevitably have a buoyancy effect on the tin bath bottom brick 1, and the flowing molten tin will also have an impact on the tin bath bottom brick 1. Therefore, during the tin bath production process, it is necessary to control the welding reliability of the fixing studs 3 that fix the tin bath bottom brick 1, so as to ensure the pull-out and torsion resistance of the fixing studs 3, and realize the tin bath bottom brick 1 is firmly and securely fixed on the tin bath steel shell 2.

[0004] like Figure 1 As shown, during the installation of the bottom bricks of the tin bath at the tin bath production site, when inspecting the welding reliability of the fixing studs 3 welded to the bottom plate of the tin bath steel shell 2, the usual method is to directly place the nut 4 onto the fixing stud 3 welded to the tin bath steel shell 2 using a socket 5 and a torque wrench, and then continuously tighten the nut 4 downwards until the torque value of the torque wrench reaches the torque verification set value. If the fixing stud 3 does not deform or break during this process, it indicates that the welding of the fixing stud 3 is qualified; otherwise, the welding of the fixing stud 3 is unqualified. However, for the above method of torque testing of fixing studs, such as... Figure 1As shown, because the connecting thread of the fixing stud 3 welded on the bottom plate of the tin trough steel shell 2 penetrates into the bottom brick fixing hole 1-1 of the tin trough bottom brick 1 from the top end of the stud, in the process of continuously screwing the nut 4 along the fixing stud 3 downwards, the nut 4 will continuously move downwards along the connecting thread of the fixing stud 3 into the bottom brick fixing hole 1-1, and the sleeve 5 will also enter the bottom brick fixing hole 1-1 along with the nut 4, when the nut 4 is screwed, the sleeve 5 entering the bottom brick fixing hole 1-1 will inevitably interfere with and damage the hole wall of the bottom brick fixing hole 1-1, and more seriously, the sleeve 5 entering the bottom brick fixing hole 1-1 will be stuck between the nut 4 and the bottom brick fixing hole 1-1 and cannot work, affecting normal production; meanwhile, the nut 4 entering the bottom brick fixing hole 1-1 is also very difficult to take out with the sleeve 5, and the task is arduous.

Obviously, the following embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0041] This invention provides a support device for assisting in detecting the torque of the fixing studs of the solder bath bottom brick. By setting up the support device, it effectively prevents the nut from being screwed downwards into the fixing hole of the solder bath bottom brick during torque testing. Figure 2 As shown in Figure -3, the tin bath is a tank-type structure formed by lining the tin bath steel shell 2 with refractory tin bath bottom bricks 1, used to hold molten tin. To prevent the tin bath bottom bricks from floating up with the molten tin, stepped holes are provided on the tin bath bottom bricks 1, which are vertically connected. The stepped holes include a bottom brick fixing hole 1-1 located below the tin bath bottom bricks 1 and a sealing hole 1-2 located above the tin bath bottom bricks 1. The bottom brick fixing hole 1-1 and the sealing hole 1-2 are vertically connected. Preferably, the upper diameter is a frustum-shaped hole smaller than the lower diameter. The bottom brick fixing hole 1-1 is preferably a cylindrical hole with an upper diameter equal to the lower diameter. The lower diameter of the sealing hole 1-2 is larger than the diameter of the bottom brick fixing hole 1-1. A stepped plane 1-3 is formed at the connection between the sealing hole 1-2 and the bottom brick fixing hole 1-1. The fixing stud 3, which is welded to the bottom plate of the tin bath steel shell 2, extends upward through the bottom brick fixing hole 1-1, thereby allowing the bottom brick 1 of the tin bath to pass through the bottom brick fixing hole 1-1.

[0042] The support device 6 of the application for assisting in detecting the torsion of the fixing stud of the tin trough bottom brick comprises a support washer 6-1 and a traction rod 6-2 fixed on the upper surface of the support washer 6-1, and is used for sleeving the support washer 6-1 on the fixing stud 3 from above by the traction rod 6-2 before the torsion detection of the fixing stud 3 by the nut 4 cooperating with the sleeve 5 and the torque wrench, so as to prevent the nut 4 from rotating into the bottom brick fixing hole 1-1 along the fixing stud 3 downward when the torsion detection is performed. Thus, the support device 6 of the application sleeves the support washer 6-1 on the fixing stud 3 between the nut 4 and the bottom brick fixing hole 1-1 of the tin trough bottom brick 1, and the support washer 6-1 blocks the bottom brick fixing hole 1-1 at the hole opening of the bottom brick fixing hole 1-1, so that the nut 4 is effectively prevented from rotating into the bottom brick fixing hole 1-1 along the fixing stud 3 downward when the torsion detection of the fixing stud 3 is performed, the sleeve 5 is prevented from entering the bottom brick fixing hole 1-1 along with the nut 4, the damage of the bottom brick fixing hole 1-1 caused by the sleeve 5 is avoided, the sleeve 5 is prevented from being stuck between the nut 4 and the bottom brick fixing hole 1-1 to affect the normal production, and the technical problem of difficulty in taking out the nut 4 caused by the nut 4 deeply entering the bottom brick fixing hole 1-1 is solved.
