Description

Technical Field

[0001] The invention belongs to the field of installation and maintenance of large-scale smelting equipment, and in particular relates to a lifting wheel supporting replacement device for a walking-beam heating furnace. Background Art

[0002] The heating furnace of the steel rolling production line is mainly of the walking beam type. The working principle is to set a lifting wheel under the lifting frame. The lifting wheel slides up and down on the inclined guide surface of the lifting slide, forming a rectangular action cycle with translation and lifting action to complete the continuous forward displacement of the steel billet. At present, the heating furnace has 24 lifting wheels installed under the lifting frame. The lifting wheel itself bears a large load. Due to long-term use, the wear of the lifting wheel will inevitably increase, thereby affecting the accuracy of the entire lifting system. When all the working surfaces of the lifting wheel are worn, the lifting wheel needs to be replaced. The key step is to lift the lifting frame so that the lifting wheel does not contact the guide surface, and then remove and replace the lifting wheel.

[0003] There are heavy parts such as support beams, translation wheels, sealed water tanks and even steel billets on the top of the lifting frame, and the entire load is very large. The traditional way of maintenance of the lifting frame is to place a large bracket tooling under the lifting frame, and then use an ordinary vertical 100-ton jack to lift it. However, the working space at the bottom of the heating furnace is originally very limited, and the tooling is very heavy, making it even more inconvenient to carry it back and forth. It takes 8 maintenance personnel to work for 8 hours to complete the work, and the work efficiency is low. At the same time, the bottom of the heating furnace is a high-temperature gas working environment, and long-term furnace bottom operations also pose a great safety risk. In addition, the tonnage of the lifting wheel is also large, and the installation and operation space is limited. Because the lifting wheel needs to be separated from the lifting slide, that is, the lifting wheel needs to be kept in a suspended state for replacement, there is a lack of lifting equipment, and the replacement is difficult and the safety risk is high. Therefore, it is necessary to design a device to improve the efficiency of replacement. Summary of the invention

[0004] The purpose of the present invention is to provide a supporting replacement device for the lifting wheels of a walking heating furnace. The present invention supports the lifting frame by arranging a lifting platform above the two side arms of a movable U-shaped base, so that the lifting wheels are separated from the guide surface of the lifting slide and are no longer subjected to force, thereby facilitating the disassembly and assembly of the lifting wheels. Since the movable U-shaped base is flat, the position of the replacement device is adjusted by using the movable U-shaped base to move the lifting platform to the bottom of the lifting frame, which is suitable for fixing the lifting frame in a narrow space. The present invention uses clamping claws to fix the lifting wheels and at the same time arranges a claw moving mechanism between the two side arms of the movable U-shaped base for moving the position of the clamping claws, thereby realizing the consignment of the lifting wheels, effectively solving the problems of small operating space and heavy weight of the lifting wheels, being safer, and significantly improving the replacement efficiency of the lifting wheels.
