Description

Technical Field

[0001] The utility model relates to the technical field of sintering machine trolleys, in particular to a sintering machine trolley wheel disassembly device. Background Art

[0002] A sintering machine is used to heat a mixture of powdered or granular iron ore, flux, and fuel under certain conditions, partially melting and condensing it to form a strong, lumpy material called sinter. It is the primary equipment used in sintering plants to sinter fines. The trolley is the core operating component of the sintering machine. As a mobile platform, it moves along the sintering machine's tracks, allowing the sintered material to undergo the entire sintering process, from preheating and combustion to cooling.

[0003] Modern large-scale sintering machines are large in scale and have long production lines. The trolleys are not only large in size but also numerous (nearly 200). Each trolley is equipped with a card wheel and a trolley wheel (such as Figure 1 As shown in the figure, bearings are installed between the trolley wheels and the axles. Since the trolley operates under harsh working conditions such as high temperature and heavy load, the bearings on it may deform and damage after a period of operation. Therefore, the bearings need to be replaced regularly. To replace the bearings, the trolley wheels must be disassembled first. However, since the trolley wheels and bearings have an interference fit, the interference fit is large and is affected by bearing deformation, making the trolley wheels difficult to disassemble. The workers consume a lot of physical energy during disassembly, and the efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide a sintering machine trolley wheel disassembly device, which can efficiently disassemble the sintering machine trolley wheel, reduce the physical consumption of workers, and improve the disassembly efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a sintering machine trolley wheel disassembly device, comprising a mobile platform, a lifting mechanism is provided on the mobile platform, a disassembly assembly is provided on the lifting end of the lifting mechanism, and the disassembly assembly includes two parallel vertical plates, one of which is provided with a bayonet at the lower end of the vertical plate, the width of the bayonet is greater than the diameter of the clamping wheel and smaller than the outer diameter of the trolley wheel, and the other vertical plate is provided with a push rod that cooperates with the bayonet.

[0006] A further improvement of the present invention is that the lifting mechanism includes a bracket arranged on the mobile platform, a hoist is provided on the bracket, and the lifting end of the hoist is provided with the disassembly assembly.

[0007] A further improvement of the present invention is that the disassembly assembly further includes a connecting plate arranged between the two vertical plates, and the connecting plate and the vertical plates are arranged perpendicular to each other.

[0008] A further improvement of the present invention is that the top rod is arranged horizontally, and one end thereof is fixed on the vertical plate.

[0009] A further improved solution of the present invention is that the top rod is provided on one side of the vertical plate, and reinforcing ribs are provided on the other side.

[0010] A further improvement of the present invention is that the upper ends of the two connecting plates are symmetrically provided with lifting ears.

[0011] A further improvement of the present invention is that the mobile platform is further provided with a control cabinet and a motor for providing power to the lifting mechanism and the mandrel.

[0012] A further improved solution of the present invention is that the push rod is arranged between the two vertical plates and is a hydraulic push rod.

[0013] The beneficial effects of the present invention are:

[0014] The utility model can replace manpower for disassembly by arranging a lifting component and a disassembly component, can efficiently disassemble the trolley wheel of the sintering machine, reduces the physical consumption of workers, and improves the disassembly efficiency.

[0015] The utility model provides a bayonet with a width greater than the diameter of the clamping wheel and smaller than the outer diameter of the trolley wheel on the vertical plate. The clamping wheel is positioned in the bayonet by lowering the vertical plate, and the push rod supports the wheel axle and then continues to extend, thereby driving the vertical plate to move. Because the bayonet width is smaller than the outer diameter of the trolley wheel, the vertical plate with the bayonet can support the trolley wheel and gradually remove it. The disassembly is simple and convenient by utilizing the diameter difference between the trolley wheel and the clamping wheel on the trolley.

[0016] The utility model moves through a mobile platform, reducing the physical effort of carrying tools, and drives the disassembly components to rise and fall through a lifting mechanism, which reduces the physical effort of adjusting the position of the bayonet compared to manually lifting the disassembly components, further reducing physical effort.
