Abstract

The invention relates to a flame spreading combustion test device, which comprises a specimen adjustment system and a combustor control system. The specimen adjustment system comprises a left hand wheel which is fixedly connected with a left horizontal shaft. The left horizontal shaft is connected with a left perpendicular shaft through a first bevel gear pair. The left perpendicular shaft is connected with a left lead screw through a cross shaft coupling. A left nut is sleeved on the left lead screw. A specimen fixture is fixed on the left nut. The combustor control system comprises a right hand wheel which is fixedly connected with a right horizontal shaft. The right horizontal shaft is connected with a right perpendicular shaft through a second bevel gear pair. The right perpendicular shaft is connected with a right lead screw through a third bevel gear pair. A right nut is sleeved on the right lead screw, and is fixed at the bottom of a combustor seat. A rotating shaft is arranged on the upper end part of the combustor seat, and is fixedly connected with a combustor. One end of the rotating shaft is fixedly connected with one end of a rotating arm of which the other end is movably matched with a guide groove on a bracket. The device is easy to operate, low in manufacture cost and high in test accuracy.

Description

technical field [0001] The invention relates to the field of fire hazard test equipment, in particular to a fire hazard test device for combustible materials. Background technique [0002] The flame spread combustion test is mainly used to assess the fire hazard of electrical and electronic components and components, solid electrical insulation materials or other combustible materials. For example, according to the provisions of the standard GB / T21762-2008 / IEC61537:2006, it is necessary to conduct a flame spread test on the material of the cable tray to evaluate its flame retardancy. In order to ensure the accuracy of the flame spread combustion test, the following requirements are required for this project: 1. The flame of the sample and the burner is always in the state required by the standard; 2. The flame temperature of the burner is within the range required by the standard. [0003] Currently, the devices used in the flame spread test are complex in operation, high i...
