Description

Technical Field

[0001] This utility model relates to the track of a ring cooler. Background Technology

[0002] With the widespread use of water-sealed annular coolers, most annular coolers used in sintering now rotate synchronously with the track and the rotating frame. During operation, wear, cracking, and dents in the support rollers can easily cause track deformation and breakage. Gaps or breaks in the track can cause the annular cooler to sink during operation, leading to jamming between the trolley within the rotating frame and the middle, end seals, and water tanks of the annular cooler, resulting in malfunctions or even complete shutdowns. The usual solution after such a failure is to replace the track; however, this requires significant downtime, interrupting the entire production line and causing substantial economic losses. Furthermore, replacing the track is extremely difficult due to the annular cooler being carried along with material.

[0003] To avoid prolonged downtime for repairs due to track cracking in the annular cooler, there is an urgent need to design a rapid track repair solution to maintain the continuous operation of the annular cooler and ensure production. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a track repair structure for an annular cooler, which can quickly repair the cracked parts of the track of the annular cooler online, avoiding long-term downtime for repair and affecting the production schedule.

[0005] The technical solution adopted by this utility model to solve the above problems is: a ring cooler track repair structure, characterized in that: it includes a repair workpiece and a connector, the repair workpiece includes a panel and a base plate, the panel is set perpendicularly to the base plate, the panel and the track are provided with corresponding connecting holes, the connector passes through the connecting holes to fix the panel on the track, the panel covers the defects of the track, the base plate is fixedly connected to the panel, and the bottom surface of the base plate is flush with the working bottom surface of the track.

[0006] Preferably, a cut is made in the area where the defect is located in the track. The cut covers the defect location and removes the defect completely. The opening width of the cut corresponds to the length of the base plate, so that both ends of the base plate are respectively connected to the track at both ends of the cut.

[0007] Preferably, there are two panels arranged at a distance from each other, and the two panels are fixed to the inner and outer sides of the track, respectively. The two panels clamp the track, which helps to improve the mechanical strength of the track repair location.

[0008] Preferably, the upper edge of the panel is provided with a notch to make way for the original fasteners on the track, so that the panel does not interfere with the position of the original fasteners on the track, ensuring that the repaired workpiece is installed in place.

[0009] Preferably, the contact surface between the panel and the track is fully welded and fixed, and the contact position between the base plate and the track is welded and fixed, further improving the connection strength between the repaired workpiece and the track.

[0010] Compared with the prior art, the advantages of this utility model are as follows: The ring cooler track repair structure claimed in this application can quickly repair the cracked location of the track, ensuring that the ring cooler can operate normally until the next maintenance cycle of the equipment, avoiding long-term downtime, ensuring production continuity, avoiding waste of output, improving maintenance efficiency, and reducing the consumption of ring cooler spare parts, etc. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings. The embodiments described are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] like Figure 1-5As shown, this embodiment of a ring cooler track repair structure includes a repair workpiece and connecting bolts 5. The repair workpiece includes two oppositely arranged panels 6 and a base plate 7. The two panels 6 are perpendicular to the base plate 7, and the base plate 7 is fixedly connected to the panels 6. A cutout is provided at the defect location of the track 2, covering and completely removing the defect. Corresponding connecting holes are provided on the two panels 6 and the track 2. The connecting bolts 5 are inserted into the connecting holes of the panels 6 and the track 2 to fix the two panels 6 to the inner and outer sides of the track 2. The panels 2 cover the cutout. The contact surfaces of the panels 6 and the track 2 are fully welded and fixed, and the opening width of the cutout is consistent with the length of the base plate 7, so that both ends of the base plate are respectively connected to the track at both ends of the cutout. At the same time, the bottom surface of the base plate is flush with the working bottom surface of the track. A recess 8 is provided on the upper edge of the panel 6 to make way for the original fixing parts on the track.

[0019] After the track develops a crack or gap, it will sink when it reaches the support roller. This sinking will cause the rotating body of the annular cooler to jam against the fixed water tank or sealing device, preventing the annular cooler from operating normally. The repair method for the track is as follows:

[0020] Step 1: After the gap occurs, we first cut and smooth the track gap to form a cutout, ensuring that the repair tool can be properly placed into the cutout. The best position for the repair workpiece to be placed into the cutout is when the base plate is flush with the bottom of the track.

[0021] Step 2: If the track fixing bolt 4 interferes with the panel during the repair process, cut and adjust the jamming part of the panel to form a notch to ensure that the repaired workpiece can be installed normally into the cut position.

[0022] Step 3: Weld the base plate to the base of the track, then drill holes in the track according to the connection holes on the panel, and then fix it with connecting bolts.

[0023] Step 4: Finally, fully weld all contact surfaces between the panel and the track that can be welded to strengthen the fixing strength and prevent cracking and falling off during operation.

[0024] It improves equipment uptime, with downtime being negligible compared to track replacement; reduces spare parts and material consumption, lowering spare parts costs; enhances safety, preventing safety hazards caused by high temperatures and material-carrying changes during online track replacement; saves labor, reducing personnel work on equipment repair and replacement; and reduces energy consumption, minimizing energy consumption and waste caused by cooling during material-carrying downtime.

[0025] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
