Background

In the steel smelting production process, the sintering ingredients are fed by a disc feeder and are metered by an electronic belt scale. The belt weigher is used for sintering and proportioning, metering the raw material dosage and the sinter ore yield, and is a vital device. The belt weigher is used as dynamic metering equipment, the static precision reaches 0.5 percent, but the dynamic precision is low (0.5 to 5 percent) and the stability is poor, so that the belt weigher needs routine maintenance (peeling, zero calibration, lubrication, scale frame cleaning and the like) by post operators. Therefore, a professional is required to check the weighing precision of the belt scale regularly, and two checking methods of the belt scale are available, namely chain code checking and physical checking, wherein the chain code checking is most commonly used. And chain code checking: under the condition that the belt conveyor is in no-load state and the belt conveyor is free of sundries and sticky materials, according to different measuring ranges (t/h) of the belt conveyor scale, chain weight of 30% -80% of the measuring range is selected, the chain weight is flatly placed on a weighing section of the belt conveyor scale, one end of the chain weight is fixed, and the belt conveyor checks the weighing precision of the belt conveyor scale under the action of the chain weight load.

The height of the belt weigher used for sintering is 300 mm-1.4 m, the weighing section of the belt weigher is strictly prohibited to be trodden in the process of calibrating the weigher, but no operation platform is arranged on the side surface and the upper part of the belt conveyor. At present, when the scale is calibrated, a chain needs to be stacked on a belt conveyor, and the difficulty and the time for taking the chain code away from the belt conveyor subsequently are high. The light chain weight (30 kg/m) requires two or three people to lift, and the heavy chain weight (150 kg/m) requires three or four people to lift. When the chain code is put on the belt conveyor and taken away after the calibration is finished, the scale frame of the belt scale is inevitably trodden, so that the weighing precision of the calibrated belt scale generates errors, and a 'climbing device for installing the chain code of the belt scale' needs to appear.
