Problems solved by technology

[0005] The existing sintering machine wheel state detection technology mainly relies on manual observation of the wheel rotation of the trolley during operation. A sintering machine has hundreds or even thousands of trolley wheels, and manual detection requires a lot of manpower.

Embodiment 1

[0026] like figure 1 As shown, the principle of the method for detecting the wheel state of the sintering machine of the present invention is as follows: the failure of the wheel 1 on the sintering machine trolley 5 starts from the damage of the wheel bearing of the sintering machine. The wheel 1 on the outer ring of the bearing shakes, and the wheel 1 after shaking will accelerate the further damage of the damaged wheel bearing of the wheel during the high load of the trolley, the vibration and impact of tipping, and finally the outer ring of the bearing together with the The wheels fell together. The self-weight of each sintering machine trolley is about X tons, and the material on the trolley during production and operation is also about Y tons. At this time, the total weight of each trolley = X+Y tons, and the total weight of each trolley depends on X+Y The support of the four wheels 1 of the trolley runs on the circulating track 3 of the sintering machine.

Embodiment 2

[0039] A method for detecting the wheel state of a sintering machine. The difference between Embodiment 2 and Embodiment 1 is that the out-of-tolerance method for judging in step 4 is as follows: first, the wheel fault judgment range reference value P1 is set by the detection parameter setting device. Usually, The value range of P1 is 0.1~0.9; then the pressure value H received by the four pressure sensors will be obtained by the calculation control device A 、H B 、H C 、H D Take the average value H; divide the pressure values ​​received by the four pressure sensors by H to obtain I A , I B , I C , I D , when (I A , I B , I C , I D )∈(1±P1) is normal, when I A , I B , I C , I D When any one of them does not belong to (1±P1), it is an out-of-tolerance fault.

Abstract

The invention relates to the field of raw material sintering in metallurgy iron manufacture, in particular to a loop wheel machine operational state detecting method of sintering machines in iron manufacture sintering. A wheel state detecting method of sintering machines includes: firstly, confirming the number of loop wheel machines, sequence number arrangement is carried out on all loop wheel machines along the operating direction of the loop wheel machines; then, corresponding sequence numbers with detecting values of four pressure sensors, using an ultra difference method to carry out judgment through the detecting values of the four pressure sensors, confirming breakdown wheels. According to working states of the loop wheel machines of the sintering machines, the wheel state detecting method of sintering machines is capable of achieving automatically detecting states of wheels during operation on line through detection that whether bearing force is in accordance or not when four wheels of a loop wheel machine operates, and the conditions that degradation of wheel states is forecasted in advance, or wheels fall off possibly are achieved, and examining and repairing the wheels designedly is achieved, so that operating efficiency of the sintering machines is improved, and damage of stopping production is reduced.

Description

technical field [0001] The invention relates to the field of raw material sintering in metallurgical ironmaking, in particular to a method for detecting the running state of a sintering machine trolley in ironmaking raw material sintering. Background technique [0002] The sintering machine has many identical trolleys connected end-to-end to form a chain, and runs in an elliptical closed cycle on the running track of the sintering machine trolleys. The sintering machine trolleys load the sintering mixture from the head of the sintering machine one by one, and then run along the upper running track to the tail of the machine. Afterwards, it is tipped along the circumference of the running track, and the sintered products are dumped onto the equipment in the next process in turn. After dumping the sintered products, the empty trolley continues to return to the head of the sintering machine along the lower running track. The circle is turned over to the upper running track of ...
