Description

technical field [0001] The invention mainly relates to a coal grate under the train coal dumper and a coal grate on the coal pit or other grates on the hopper in the coal unloading room of the car. Shuji. Background technique [0002] In enterprises that use a large amount of coal (or other bulk materials) in industries such as electric power and metallurgy, usually, coal transported into the plant by train or automobile must be screened for the first time through coal grates. In the past, the sundries remaining on the coal grate after screening, such as large pieces of coal, coal gangue, straw ropes, woven bags, etc., were all handled manually. With the development and progress of society, manual cleaning in such a harsh environment can no longer meet the requirements, efficiency and pace of modern production, and manual operation will be replaced by high-efficiency machinery and equipment. As a result, various types of dredgers have emerged. [0003] At present, the dre...

Problems solved by technology

Therefore, the travel force of the equipment is limited, and when the equipment encounters a slightly larger resistance, it is very easy to slip

The running mechanism of all existing domestic similar equipment relies on the rolling friction between the steel wheel (including two-wheel drive or four-wheel drive) and the steel rail, which is very easy to slip, especially when there is water, mud or wet on the rail surface. When the coal and the resistance to travel are slightly greater, slippage occurs. At this time, the machine can only stop on the coal grate, and cannot advance or retreat, and the dumper cannot unload coal normally.

None of the existing domestic equipment is equipped with a hand-operated device. When the machine slips or stops or the electrical appliances fail, the machine cannot be returned to the machine room, which affects the unloading operation.
