Description
BREAKING DETECTION DEVICE AND METHOD FOR DUMBBELL
PIN CONNECTED TO MIDDLE TROUGH
BACKGROUND
Technical Field The present invention relates to a pin breaking detection device and method, and more particularly to a breaking detection device and method for a dumbbell pin connected to a middle trough.
Related Art In a propulsion process of a fully mechanized coal mining face, a middle trough of a scraper conveyor is susceptible to a combined action of various loads such as a dead load, a coal carrying force and a pushing resistance, and is also affected by the straightness of the scraper conveyor, ground fluctuation, a bending angle between any adjacent middle trough sections and the own strength of a dumbbell pin, thus making it much easier to result in wearing and breaking of the middle trough and the dumbbell pin, or to seriously result in connection displacement or disconnection of the middle trough. The connection strength of a middle trough dumbbell pin seat is much stronger than that of the dumbbell pin, and once the dumbbell pin is broken, it can be judged that the middle trough fails in connection.
At present, in a mine production process of the fully mechanized coal mining face, a breaking failure of a dumbbell pin connected to a middle trough is still detected in a traditional artificial manner, it is quite difficult to artificially distinguish the non-obvious displacement or disconnection of the middle trough and to replace a broken dumbbell pin in time, so a great potential safety hazard exists.
