[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1 As shown, a piston guide wheel refueling device for a blast furnace gas holder includes a blast furnace gas holder. The edge of the blast furnace gas holder is set as a cabinet wall column 1. The cabinet wall column 1 serves as the main load-bearing structure of the gas holder and supports other components to ensure overall stability during operation. The cabinet wall column 1 is made of corrosion-resistant steel or a composite structure, which has strong resistance to deformation and adapts to the complex internal environment of the gas holder.

[0022] The blast furnace gas holder is equipped with a guide wheel platform 5, which serves as the mounting base for the piston support 6 and provides working space for maintenance personnel. It also supports the guide wheel system and auxiliary equipment. The piston support 6 is installed above the guide wheel platform 5. The piston support 6 fixes the guide wheel 2 on the piston and supports the overall piston structure, transmitting the load during piston movement to the guide wheel platform 5.

[0023] A platform ladder 4 is installed between the piston support 6 and the guide wheel platform 5, providing a safe passage for maintenance personnel to access the piston support 6 from the guide wheel platform 5, facilitating equipment maintenance and inspection. An upper piston guide wheel 2 is installed on the edge of the piston support 6. The upper piston guide wheel 2 guides the vertical movement of the piston support 6 by rolling against the cabinet wall column 1, reducing frictional resistance and preventing piston jamming. An oil injection conduit 3 is installed on the cabinet wall column 1, delivering lubricating oil from the oil supply system to the oil filling outlet 7, achieving directional and quantitative delivery of lubricant. The end of the oil injection conduit 3 is designated as the oil filling outlet 7, which is fixed on the piston support 6 and aligned with the upper piston guide wheel 2. The oil filling outlet 7 precisely sprays the lubricating oil delivered by the oil injection conduit 3 onto the lubrication point of the upper piston guide wheel 2, achieving automatic lubrication.

[0024] The specific design of the aforementioned key components will be discussed in detail below:

[0025] The piston upper guide wheel 2 adopts a polyurethane-coated steel core composite structure. The rim of the piston upper guide wheel 2 is provided with a V-shaped guide groove, and the axle is equipped with a double-layer sealed bearing. The steel core is forged from 45# steel with a carburized surface treatment, providing high-strength support. The polyurethane coating layer is 15-20mm thick, covering the rim and contact surface, providing both elasticity and wear resistance. The V-shaped guide groove has a 60° opening angle, a depth of 8-10mm, and a contact surface width of 30-40mm with the cabinet wall column 1, increasing the contact area and dispersing pressure. The axle uses a 6206-2RS type deep groove ball bearing with double-sided contact sealing, filled with lithium-based grease, and has a dustproof and waterproof rating of IP65.

[0026] The guide wheel platform 5 is welded from Q345B steel plate. The surface of the guide wheel platform 5 has diamond-shaped anti-slip ridges, and a 150mm high guardrail is welded to its edge. The platform thickness is 12mm, the diamond-shaped anti-slip ridge height is 2mm, the diamond grid size is 30×30mm, the surface is sandblasted, the guardrail posts are spaced 1.2m apart, the horizontal bars are made of Φ25mm round steel, and the vertical bar spacing is ≤200mm, conforming to the GB 4053.3 guardrail height standard.

[0027] The refueling outlet 7 adopts an adjustable-angle nozzle structure, including a spherical hinge joint and a locking nut. The nozzle outlet diameter is 3-5mm, and the vertical distance from the outlet end to the lubrication point of the piston upper guide wheel 2 is 50-80mm. The spherical hinge joint allows the nozzle to be adjusted within a ±15° range, and the locking nut torque is set to 10-15 N·m to prevent loosening. The nozzle outlet diameter adopts a stepped variable diameter structure, with an inlet diameter of 8mm and an outlet diameter of 3-5mm, allowing for nozzle replacement to adapt to different viscosity lubricating oils.

[0028] The piston support 6 adopts an H-shaped steel frame structure, and rubber shock-absorbing pads are provided at the connection between the piston support 6 and the guide wheel platform 5. The main beam is made of HM300×200×8×12 steel, with 10mm thick reinforcing plates welded at the joints. The overall deflection of the frame is ≤L / 500. The rubber shock-absorbing pads are made of neoprene rubber with a pre-compression of 15%.

[0029] The platform ladder 4 has a step spacing of 280-300mm, and the handrail tubes on both sides of the platform ladder 4 have a diameter of Φ42mm. The overall structure can withstand concentrated loads, ensuring climbing safety.

[0030] The oil injection conduit 3 is a multi-layer composite hose. The outer layer of the hose is an oil-resistant polyurethane layer, the middle layer is a stainless steel wire braided reinforcement layer, and the inner layer is a nitrile rubber oil-conducting layer. Guide rings are provided at the fixing points of the oil injection conduit 3 on the cabinet wall column 1. The guide rings are spaced 2.0-3.0m apart and form a sliding fit with the oil injection conduit 3. The composite hose has a burst pressure ≥30MPa and a bending radius ≤8 times the pipe diameter, adapting to the complex movement trajectory of piston lifting and lowering. The guide rings reduce hose wear and extend service life.
