Description

Technical Field

[0001] The utility model relates to the field of blowtorch combustion test, in particular to a combined device for automatically realizing a conveyor belt blowtorch combustion test. Background Art

[0002] According to MT / T914-2019, flame-retardant conveyor belts with fabric cores for coal mines need to undergo a blowtorch combustion test. During the test, the test is carried out in a combustion box under weak light. The air flow around the test piece should be as small as possible so as not to affect the flame of the burning test piece. The test piece should be perpendicular to the door of the combustion box so that both sides of the test piece can be observed. During the test, the test piece is placed in the flame and burned for 30 seconds, then the blowtorch that is not extinguished is removed. From then on, a stopwatch is used to measure the flame burning time and the flameless burning time on the test piece.

[0003] Three inspectors are required during the test. One inspector records the time when the test piece burns in the flame for 30 seconds and then removes the blowtorch. The other two inspectors respectively record the flaming burning time and the flameless burning time after the blowtorch is removed. This method wastes manpower and also produces a certain time error in the process of manually observing the flaming burning time and the flameless burning time with the eyes and counting the stopwatch, resulting in inaccurate recorded time.
