Embodiment Construction

[0040] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] like figure 2 As shown, the grate bars on the sintering trolley all have a fixed number, so as to realize the close arrangement of each other. When more than two grating bars are missing due to wear, it will cause loosening between the original tightly arranged grating bars, which often causes the sintering trolley to turn over from the upper track to the lower track, and the lower track to the upper track. When on the ring track, the grate bar will further drop due to loss of support on the trolley. Therefore, this technology detects the sintering trolley running on the lower ring track in advance, so as to avoid the trolley missing the grate bar from repeatedly turning over.

[0042] like image 3 Shown, detection method of the present invention is, utilizes the feature that the plane formed when the grate bar 2 a...

Abstract

The invention discloses a detection device for detecting absence of a trolley fire grate bar. The detection device comprises a detection rod device, a fixing rod and a limiting device. The detection rod device comprises a detection rod, a detection wheel and a counter weight. An included angle is formed between the upper end and the lower end of the detection rod, and the inclination direction of the upper end of the detection rod is coincident with the running direction of a trolley. The middle of the detection rod comprises a detection rod fixing hole, and the fixing rod can be placed in the detection rod fixing hole. The detection wheel is arranged on the head portion at the upper end of the detection rod, and the counter weight is arranged at the bottom of the lower end of the detection rod. The limiting device is arranged near the counter weight, and the counter weight makes contact with the limiting device when the detection rod device rotates. A detection method includes the steps that the detection device gives an alarm when the fire grate bar is absent; PLC alarming information is collected; the frequency of absence signals of the fire grate bar is analyzed; the position of the absent fire grate bar is determined; supplement of the fire grate bar is carried out.

Description

technical field [0001] The invention relates to a detection device and a detection method for a sintering trolley, and more specifically, to a detection device and a detection method for detecting the absence of grate bars on a trolley. Background technique [0002] The sintering trolley is one of the important parts of the sintering machine, which is composed of car body, baffle, heat insulation, furnace grate, elastic compensation type sealing device, card wheel, wheel and axle and other components. A closed sintering machine ring is formed by several trolleys. The sintering trolley on the upward track is loaded at the head, ignited and ventilated for sintering, and runs to the tail to pour out the sintered ore, and then runs to the down track, repeating the cycle. [0003] The grate bars of the sintering trolley are located at the bottom of the sintering trolley, and are used to support the combustion of iron-containing materials at a certain speed under the action of dr...
