Description

Technical Field

[0001] This utility model relates to the field of walking beam furnace technology, and in particular to a mechanical translation component for a heating furnace walking beam. Background Technology

[0002] A walking beam furnace is a continuous heating furnace that moves the billet forward step by step, involving walking beam machinery. The studs connecting the walking beam machinery's translational track have repeatedly experienced breakage issues. Due to the track structure limitations, replacing the broken studs requires first removing the track, then taking out the broken wire, reinstalling the track, and finally restoring the studs after the track is properly installed. The maintenance time is approximately 4-6 hours.

[0003] This resulted in the inability to handle the aforementioned replacement operations during daily production, both during the roll changing time and the intensification time on the production line. The problem of cutting off the connecting studs of the stepping mechanical translation track of the heating furnace became a bottleneck restricting the smooth and stable operation of the heating furnace. Utility Model Content

[0004] To address the aforementioned problems, this application provides a stepping mechanical translation component for a heating furnace.

[0005] This application provides a walking beam mechanical translation assembly for a heating furnace, including a translation frame, a translation base plate, a translation track, multiple first bolts, and multiple second bolts. The translation frame has multiple first through holes and multiple second through holes distributed along the thickness direction. The translation frame is configured to install water beam columns for supporting slabs. The translation base plate is located on one side of the thickness of the translation frame and has multiple third through holes and multiple first groove through holes distributed along the thickness direction. The third through holes correspond one-to-one with the first through holes, and the first groove through holes correspond one-to-one with the second through holes. In a one-to-one correspondence, the translation track is located on the thickness side of the translation base plate away from the translation frame. The translation track has a second sink groove through hole, which corresponds one-to-one with the third through hole. The translation track is driven by the drive mechanism of the heating furnace walking machine. Multiple first bolts are installed in the first sink groove through hole and the second through hole with nuts. The head of the first bolt is located in the sink groove of the first sink groove through hole. Multiple second bolts are installed in the second sink groove through hole, the third through hole and the first through hole with nuts. The head of the second bolt is located in the sink groove of the second sink groove through hole.

[0006] In some implementations, the first through hole and the second through hole are alternately distributed along the length of the translation frame.

[0007] In some embodiments, at least two first through holes are provided in the width direction of the translation frame.

[0008] In some embodiments, two first through holes are provided in the width direction of the translation frame, and they are symmetrically distributed along the vertical center line of the translation frame.

[0009] In some embodiments, at least two second through holes are provided in the width direction of the translation frame.

[0010] In some embodiments, two second through holes are provided in the width direction of the translation frame, and they are symmetrically distributed along the vertical center line of the translation frame.

[0011] In some implementations, a washer is installed between the nut to which the first bolt is connected and the translation frame.

[0012] In some implementations, a washer is installed between the nut to which the second bolt is connected and the translation frame.

[0013] In some implementations, the nominal diameters of the first stud and the second bolt are equal.

[0014] In some implementations, both the first stud and the second bolt are M24 bolts.

[0015] The beneficial effects of this application are as follows: A heating furnace stepping machine translation component is provided, including a translation frame, a translation base plate, a translation track, multiple first bolts, and multiple second bolts. The translation frame, translation base plate, and translation track are stacked sequentially. A water beam column is installed on the translation frame to support the high-temperature slab. The lower part of the translation track contacts the drive mechanism of the heating furnace stepping machine. Driven by the drive mechanism, the heating furnace stepping machine translation component moves along a rectangular trajectory, causing the water beam column to perform a cyclical action of rising, advancing, falling, and retracting, thus moving the high-temperature slab step by step forward. Multiple first bolts, in conjunction with nuts, are installed in the first and second through holes of the sink. The translation frame and the translation base plate are connected and fastened by the multiple first bolts and nuts. The nuts connected to the first bolts are located on the upper side of the translation frame, and the heads of the first bolts are located in the first sink. In the sinker of the through hole, the translation frame and translation track are connected and fastened by multiple second bolts and nuts. The nut connected to the second bolt is located on the upper side of the translation frame, and the head of the second bolt is located in the sinker of the through hole. If the second bolt breaks, the broken part can fall from the translation track, and the on-site staff can find it in time and replace the second bolt. The replacement time only takes a few minutes. Therefore, it can be handled during the production line's roller change time or during the reinforcement time. The reinforcement time refers to the time for handling minor problems on-site, which is about 30 minutes. The reinforcement time for short-term maintenance is one of the existing operating procedures of the factory. Therefore, it is not necessary to stop the machine for emergency repair when the second bolt breaks. This is conducive to the smooth operation of the heating furnace production line, shortens the equipment failure downtime, improves production efficiency, and reduces the labor intensity of maintenance personnel.

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] Please refer to Figure 1 , Figure 1The illustration demonstrates the installation method of the original connecting stud 1 of the walking beam mechanical translation track 300 in the prior art. This original connecting stud 1 experienced a wire breakage within the translation track 300. When removing the broken wire, a small screw needs to be welded to the broken wire, and then the screw and the broken wire are removed together. In factory settings, the translation track 300 is often located approximately 3 meters above the ground. Because removing the broken wire involves welding, the entire translation track 300 needs to be pulled out before the wire can be removed. Furthermore, the original connecting stud 1 needs to be inspected under these high-altitude working conditions, resulting in low inspection efficiency and a maintenance time of 4-6 hours.

[0025] In daily production, there are roll changeover time and reinforcement time in the production line process. Reinforcement time refers to the time for handling minor on-site maintenance issues, which is about 30 minutes. Reinforcement time for short-term maintenance operations is one of the existing operating procedures in the factory. It is evident that neither the roll changeover time nor the reinforcement time can be used to perform the aforementioned broken wire removal operation. This leads to production line shutdown for inspection. The original connecting stud 1 of the stepping mechanical translation track 300 of the heating furnace has become a bottleneck restricting the smooth and stable operation of the heating furnace.

[0026] To this end, the inventor provides a heating furnace stepping mechanical translation component, hereinafter referred to as "this component," please refer to... Figures 2 to 4 This component includes a translation frame 100, a translation base plate 200, a translation track 300, multiple first bolts 400, and multiple second bolts 500. Figure 2 This demonstrates the overall layout of this component. Figure 2 The installation positions of the first bolt 400 and the second bolt 500 are shown. Figure 3 This demonstrates the specific structural form of the translation track 300 in this component. Figure 4 The first bolt 400 and nut are shown to connect and fasten the translation frame 100 and the translation base plate 200.

[0027] Please refer to the reference. Figures 2 to 4The translation frame 100, translation base plate 200, and translation track 300 are stacked sequentially. The translation base plate 200 is located on the thickness side of the translation frame 100, and the translation track 300 is located on the thickness side of the translation base plate 200 away from the translation frame 100. The translation frame 100 has multiple first through holes 110 and multiple second through holes 120 distributed along the thickness direction. The translation base plate 200 has multiple third through holes 210 and multiple first sinking through holes 220 distributed along the thickness direction. The translation track 300 has second sinking through holes 310. Specifically, the third through holes 210 correspond one-to-one with the first through holes 110, the first sinking through holes 220 correspond one-to-one with the second through holes 120, and the second sinking through holes 310 correspond one-to-one with the third through holes 210. Multiple first bolts 400 are fitted with nuts and installed in the first sinker through hole 220 and the second through hole 120. The head of the first bolt 400 is located in the sinker of the first sinker through hole 220. Multiple second bolts 500 are fitted with nuts and installed in the second sinker through hole 310, the third through hole 210 and the first through hole 110. The head of the second bolt 500 is located in the sinker of the second sinker through hole 310.

[0028] The translation frame 100 is fitted with water beam columns to support the slab. The water beam columns are mounted on the translation frame 100 and support the slab at high temperature. The translation track 300 is driven by the drive mechanism of the heating furnace stepping machine. The lower part of the translation track 300 contacts the drive mechanism of the heating furnace stepping machine. Driven by the drive mechanism of the heating furnace stepping machine, the translation component of the heating furnace stepping machine moves in a rectangular trajectory, causing the water beam columns to perform a cyclical action of rising, advancing, falling, and reversing, thus moving the slab at high temperature step by step forward.

[0029] Multiple first bolts 400 are fitted with nuts and installed in the first sinkhole 220 and the second sinkhole 120. The translation frame 100 and the translation base plate 200 are connected and fastened by the multiple first bolts 400 and nuts. The nuts connected to the first bolts 400 are located on the upper side of the translation frame 100, and the heads of the first bolts 400 are located in the sinkhole of the first sinkhole 220.

[0030] The translation frame 100 and the translation track 300 are connected and fastened by multiple second bolts 500 and nuts. The nuts connected to the second bolts 500 are located on the upper side of the translation frame 100, and the heads of the second bolts 500 are located in the groove of the second groove through hole 310. If the second bolt 500 breaks, the broken part can fall from the translation track 300, which can be detected and replaced by on-site personnel in a timely manner. The replacement time only takes a few minutes, so it can be handled during the production line roller change time or during the reinforcement time.

[0031] Therefore, it is no longer necessary to shut down the machine for emergency repairs when the second bolt 500 breaks, which is conducive to the smooth and stable operation of the heating furnace production line, shortens the downtime of equipment failure, improves production efficiency, and reduces the labor intensity of maintenance personnel.

[0032] Both the first and second studs are installed using nuts; please refer to [reference needed]. Figure 4 A washer is installed between the nut connected to the first bolt 400 and the translation frame 100. Similarly, a washer is installed between the nut connected to the second bolt 500 and the translation frame 100. The washer increases the stability of the bolt connection.

[0033] In some embodiments, the nominal diameters of the first stud and the second bolt 500 are equal, and the diameters of the first through hole 110, the second through hole 120, and the third through hole 210 are all equal.

[0034] In some implementations, both the first stud and the second bolt 500 are M24 bolts, which are hex socket head cap bolts.

[0035] In some implementation methods, please refer to Figure 2 Along the length of the translation frame 100, the first through hole 110 and the second through hole 120 are alternately distributed.

[0036] In some implementation methods, please refer to Figure 2 In the width direction of the translation frame 100, at least two first through holes 110 are provided to improve the structural stability of the component.

[0037] In some implementation methods, please refer to the reference. Figure 2 and Figure 4 In the width direction of the translation frame 100, there are two first through holes 110, which are symmetrically distributed along the vertical center line of the translation frame 100.

[0038] Similarly, in some embodiments, at least two second through holes 120 are provided in the width direction of the translation frame 100.

[0039] Similarly, in some embodiments, two second through holes 120 are provided in the width direction of the translation frame 100 and are symmetrically distributed along the vertical center line of the translation frame 100.
