Description

Technical Field

[0001] This utility model relates to the field of blast furnace ironmaking equipment maintenance technology, specifically to a special transport trolley for replacing the feeding chute. Background Technology

[0002] The blast furnace charging chute is a critical piece of equipment on the blast furnace roof and requires regular replacement. Currently, replacement operations commonly use unpowered, ordinary flatbed railcars for chute transport. This traditional method has several drawbacks: First, due to the heavy weight of the chute and tooling assembly, moving the chute relies entirely on 5-6 operators working together, resulting in extremely high labor intensity, high labor costs, and low efficiency. Second, the existing chute lacks a dedicated fixing mechanism, requiring the simultaneous use of two lifting devices—the blast furnace overhead crane and the single-beam crane on the furnace roof—when installing or dismantling the chute tooling: one lifts the chute while the other aligns and disassembles the tooling. This process is cumbersome, time-consuming, and labor-intensive, and the coordinated operation of two lifting devices in the air poses a significant safety risk; any miscoordination could easily lead to accidents such as the falling of heavy objects.

[0003] Therefore, there is an urgent need to design a special transport trolley for changing fabric chutes to solve the problems of high labor intensity, high cost, low efficiency and safety hazards of existing technologies. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a special transport trolley for changing fabric chutes.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a special transport trolley for changing fabric chutes, including a frame, a track and a winch. An angle bracket is provided on the frame, and a traveling wheel is provided at the bottom of the frame. The frame is set on the track through the traveling wheel. A winch is fixedly installed at one end of the track. The frame and the winch are slidably connected by a steel wire rope, and hooks are provided at both ends of the steel wire rope.

[0006] Specifically, the upper part of the frame is welded with an angle bracket, the bottom of the frame is connected to a traveling wheel, and both ends of the frame are equipped with traction rings, which are connected to hooks.

[0007] Specifically, the angle bracket is a bracket fixed at a specific angle, the angle bracket is triangular, and the bottom end of the angle bracket is provided with a limiting stop.

[0008] Specifically, the top of the walking wheel is connected to the bottom of the frame, and the bottom of the walking wheel is set on the track.

[0009] Specifically, a winch is provided at one end of the track, and a limiting plate is provided at the other end of the track. A pulley is fixedly installed at the lower part of the limiting plate, and the two ends of the wire rope pass through the winch and the pulley respectively and are connected to the traction rings at both ends of the frame.

[0010] Specifically, the winch includes a motor, a winch, and a control box, with the control box controlling the motor to drive the winch to move the wire rope.

[0011] This utility model has the following beneficial effects:

[0012] This utility model designs a special transport trolley for changing fabric chutes, which is highly automated and greatly reduces labor intensity: by setting up an electric winch drive mechanism, the trolley can move automatically, completely replacing the original manual pushing mode that required 5-6 people. Only one person needs to operate it remotely, saving 4-5 laborers and greatly reducing the labor intensity of workers; the operation safety is significantly improved: by integrating a fixed angle bracket, the chute can be reliably fixed at the optimal working angle, so that the disassembly and assembly of the tooling can be completed independently by a single crane, completely avoiding the huge safety risks brought about by the original two cranes working together, and fundamentally eliminating the safety hazards of high-altitude collaborative hoisting; the operation efficiency is greatly improved: the dual-vehicle collaborative operation process is reasonably designed. While one crane transports the old chute to the side for tooling disassembly, another crane can immediately transport the new chute to the workstation for tooling installation, realizing parallel operation of disassembly and installation processes. Moreover, a single crane can quickly complete the operation, significantly shortening the blast furnace shutdown maintenance time and achieving a qualitative leap in work efficiency. The structure is reasonable and highly practical: the overall structure of the device is simple and compact, the operation is stable and reliable, and the maintenance is convenient. It is specially designed for the narrow and complex maintenance environment of the blast furnace top, and has strong practicality and promotion value. Attached Figure Description
