Description

Technical Field

[0001] The utility model relates to the technical field of converter furnace body overhaul, and particularly relates to an auxiliary device for converter furnace body overhaul. Background Technique

[0002] A converter is a steelmaking device, referring to a rotatable cylindrical oxygen-blowing steelmaking container. The overhaul of the converter furnace body belongs to high-altitude operation. The original overhaul device is generally to manually erect a temporary scaffolding. After the overhaul is completed, the scaffolding needs to be removed, which is time-consuming and there are safety hazards during manual removal.

[0003] To solve the above problems, the patent publication number: CN209368311U provides a converter overhaul vehicle for converter overhaul, including a vehicle body, guide wheels, front wheels, a direction crank, a movable ladder, a vertical frame, a steel wire rope, a drum, a drum crank, a positioning disc, a positioning hole I, a positioning hole II, and a positioning rod. One end of the vertical frame and the movable ladder is fixed on the vehicle body, the drum and the drum crank are fixed on the vertical frame, and the drum and the free end of the movable ladder are connected by a steel wire rope. The height of the movable ladder is adjusted by rotating the drum crank, and the height of the movable ladder is limited by the positioning hole I, the positioning hole II, and the positioning rod, so that maintenance personnel can overhaul the furnace body. However, in this patent, the movable ladder is only pulled by a steel wire rope. When the maintenance personnel and maintenance equipment on the movable ladder are too heavy, there is a safety hazard that the front wheel side of the vehicle body tilts up. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary device for converter furnace body overhaul to solve the safety problem that when the movable ladder in the existing patent is pulled by a steel wire rope and the maintenance personnel and maintenance equipment on the movable ladder are too heavy, the front wheel side of the vehicle body tilts up.

[0005] To achieve the above purpose, the basic scheme provided by the utility model is: an auxiliary device for converter furnace body overhaul, including a support platform and a support component. An overhaul platform is hinged on the support platform. Pillars are arranged at the four corners of the bottom end of the support platform. The bottom of the free end of the overhaul platform is fixed to the pillar through the support component, and a climbing ladder is arranged on the support platform.

[0006] The principle and beneficial effects of the utility model are as follows: during use, the support platform is placed at the position to be overhauled. First, manually rotate the overhaul platform to the same plane as the support platform, and then fix the overhaul platform through the support component. The maintenance personnel climb to the overhaul platform through the climbing ladder, and at this time, the converter furnace body can be overhauled. After the overhaul is completed, the maintenance personnel climb down from the overhaul platform to the ground through the climbing ladder, and then remove the support component. At this time, the overhaul platform will naturally hang vertically on the side of the support platform due to gravity. The device has a simple structure and improves the safety of the maintenance personnel.

[0007] Scheme Two, which is the preference of the basic scheme. Protective fences are fixedly connected to the support platform and the overhaul platform respectively, increasing the safety of the device.

[0008] Solution 3, which is the optimization of the basic solution. The support component includes four U-shaped blocks and two support rods. The bottom of the free end of the inspection table is fixedly connected to two U-shaped blocks, and the opposite two columns are fixedly connected to two U-shaped blocks. Each end of each support rod is bolted to two U-shaped blocks. When in use, rotate the inspection table to the same plane as the support platform and fix the inspection table by bolting the support rods to two U-shaped blocks. When not in use, remove the support rods from the two U-shaped blocks, and the inspection table will naturally hang vertically on the side of the support platform due to gravity, reducing the space occupied by the device.

[0009] Solution 4, which is the optimization of the basic solution. Each bottom end of the column is fixedly connected with a caster, and the caster is a caster with a braking function, which is convenient for moving the support platform.

[0010] Solution 5, which is the optimization of the basic solution. A reinforcing rib is fixedly connected between the opposite two columns, which plays a role in reinforcement, thereby extending the service life of the equipment. Description of the Drawings

[0016] Embodiment

[0017] As Figures 1 to 3As shown in the figure: An auxiliary device for the overhaul of a converter furnace body includes a support platform 1 and a support assembly. A repair table 2 is hinged on the support platform 1. Pillars 5 are provided at the four corners of the bottom end of the support platform 1. The bottom of the free end of the repair table 2 is fixed to the pillar 5 through the support assembly. The support assembly includes four U-shaped blocks 12 and two support rods 13. The bottom of the free end of the repair table 2 is fixedly connected to the two U-shaped blocks 12. The two opposite pillars 5 and the two U-shaped blocks 12 are fixedly connected. Each end of the two support rods 13 is bolted to the two U-shaped blocks respectively. Protective fences 3 are fixedly connected to the support platform 1 and the repair table 2 respectively. Casters 7 are fixedly connected to the bottom ends of the two opposite pillars 5. The casters 7 are casters with a braking function. A ladder 6 is provided on the support platform 1. A reinforcing rib 9 is fixedly connected between the two opposite pillars 5.

[0018] The implementation mode of this embodiment is as follows: When in use, first move the support platform 1 to the position where the converter furnace body needs to be overhauled through the casters 7, then manually rotate the repair table 2 to the same plane as the support platform 1, and then fix the repair table 2 with the support rod 13 through bolts. The repairman can reach the repair table 2 through the ladder 6. At this time, the converter furnace body can be overhauled. When the overhaul is completed, the repairman gets off the repair table 2 to the ground through the ladder 6, and then removes the support rod 13. At this time, the repair table 2 will naturally hang vertically on the side of the support platform 1 due to gravity.
