The invention relates to a drawing tool and process for a wheel axle of a sintering pallet. The drawing tool and process for the wheel axle of the sintering pallet are used for pulling the wheel axle of the sintering trolley out of a trolley body. The drawing tool comprises a seat frame, a telescopic power cylinder and a height adjusting device, wherein the telescopic power cylinder is installed on the seat frame in a vertically movable mode; a piston rod of the telescopic power cylinder is provided with a sleeving through hole along the axis; the inner diameter of the sleeving through hole is larger than the outer diameter of the wheel axle; and the height adjusting device drives the telescopic power cylinder to move up and down. The drawing tool further comprises an axle end pressing plate which is used for being arranged on the rear axle end face of a piston rod, wherein a connecting bolt hole is formed in the axle end pressing plate, and corresponds to a bolt hole in the end face of the wheel axle. According to the drawing tool provided by the invention, in the drawing process, the wheel axle and the piston rod keep good coaxiality, the coincidence degree of the action direction of drawing force and the axis of the wheel axle is high, and the concentrated action point of the drawing force and the axis of the wheel axle tend to be concentric, so that stress on the wheel axle is more concentrated, drawing is more efficient, labor intensity is low, and working efficiency is high.
Description
technical field [0001] The invention relates to the field of ironmaking and sintering equipment, in particular to a drawing tool and process for a wheel axle of a sintering trolley. Background technique [0002] The sintering trolley is the main running part of the sintering machine, which is used for sintering iron ore powder in the sintering plant. Due to the long-term high temperature and continuous operation of the sintering table, the wheel axle of the sintering table wears out quickly, and the frequency of wheel axle replacement is relatively high. Generally, the method of offline maintenance is used for processing. The dismantling of the wheel axle of the sintering table mainly depends on the cooperation of 4 employees using 2 sets of hydraulic jacks, 2 sets of hydraulic stations, and 1 set of chain hoists. The wheel axle of the sintering table and the body of the table With assembly, it is difficult to pull out the wheel shaft with conventional tools, so the entire...
