Technical Field

[0001] The utility model relates to an offline detection device for a tension leveller, belonging to the technical field of continuous casting equipment for metallurgical steelmaking. Background Art

[0002] The tension leveller is an important device for continuous casting and pouring. Whether the tension leveller is normal has a great impact on the quality of billets. Under normal circumstances, the tension leveller uses soft reduction to cast billets. If the tension leveller is abnormal, soft reduction cannot be used normally, and the quality of the cast billets poured cannot be guaranteed. For the tension leveller repaired offline, it is impossible to determine whether it can meet the usage requirements based on experience. Sometimes, the replaced tension leveller is also abnormal and cannot operate normally, and it needs to be replaced again during the next maintenance, increasing the workload. Moreover, when replacing the tension leveller, the standing position of the personnel is narrow, and hoisting is difficult, and safety cannot be guaranteed.

[0003] In summary, how to provide an offline detection device for a tension leveller to improve the qualification rate of the online tension leveller, reduce the workload of repeatedly replacing the tension leveller, reduce the work intensity, and improve the safety of maintenance is an urgent problem to be solved at present.

[0014] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] As Figure 1 , 2 shown, an off-line detection device for a tension leveling machine in this embodiment includes a detection table. The tension leveling machine is supported on the detection table. A horizontally arranged arc calibration sample rod 10 is movably arranged on the detection table. The arc calibration sample rod 10 detects whether the roller 9 on the tension leveling machine is horizontal, so as to judge whether the bearing needs to be replaced. A water inlet joint with a valve and a water return joint with a valve are arranged at the bottom of the tension leveling machine. A water inlet pipe 8 and a water return pipe 5 are arranged on the detection table. One end of the water inlet pipe 8 is connected to the water inlet joint, and the other end of the water inlet pipe is connected to the water of the workshop equipment. One end of the water return pipe 5 is connected to the water return joint, and the other end of the water return pipe 5 is connected to the water of the workshop equipment. The water of the workshop equipment flows into the tension leveling machine through the water inlet pipe, and then flows back to the workshop equipment water through the water return pipe, forming a water cycle; by visually observing the water inlet joint and the water return joint, whether there is a leakage phenomenon. A flow meter is arranged on the water return pipe, and the flow meter detects the water flow in the water return pipe to further judge whether there is a water leakage at the water inlet joint and the water return joint.

[0016] The above-mentioned inspection table includes a platform 2, and a plurality of supporting feet 4 are symmetrically arranged at the bottom of the platform 2. A placing groove penetrating up and down is opened on one side of the platform 2. A base 6 is provided below the platform 2, and the base 6 is connected to the platform 2 through a vertically arranged connecting rod, and the base 6 corresponds to the placing groove. The tension leveling machine is arranged in the placing groove, and the bottom of the tension leveling machine is supported on the base 6 and fixed to the base 6 through two fixing bolts 7. Anti-falling plates 3 are symmetrically arranged on the top surface of the placing groove, and the anti-falling plates 3 play a role in limiting the tension leveling machine, thereby preventing the tension leveling machine from falling.

[0017] A staircase 1 is arranged on one side of the above-mentioned platform 2, which is convenient for operators to climb onto the platform.

[0018] A plurality of sample rod placing racks are respectively arranged on two symmetrically arranged supporting feet, and the plurality of sample rod placing racks are evenly spaced along the vertical direction of the supporting feet. The two ends of the arc calibration sample rod are placed on the sample rod placing racks on the same straight line. When the tension leveling machine is fixed to the base, the arc calibration sample rod is removed; when the tension leveling machine is fixed to the base, the arc calibration sample rod is placed on the rollers of the tension leveling machine, and then it is observed whether the arc calibration sample rod is horizontal.

[0019] This application simulates the production state of the tension leveling machine, thereby detecting various parameters of the tension leveling machine and judging whether the tension leveling machine can be used normally on the production line. This application improves the qualified rate of the tension leveling machine on the production line, reduces the workload of repeatedly replacing the tension leveling machine, reduces the work intensity, and improves the safety of maintenance because the tension leveling machine is overhauled offline.
