Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-combustibility detection of thermal insulation materials, and particularly relates to a non-combustibility detector for building external wall thermal insulation materials. BACKGROUND

[0002] Now, the thermal insulation system of building external walls is being applied more and more in domestic construction engineering, and the fire hazard is the most important and to-be-solved problem for thermal insulation materials. The thermal insulation materials are divided into A, B and C grades, and the A-grade material is also called non-combustible building material, that is, a material that almost does not burn. In order to prevent the fire hazard, it is necessary to detect the non-combustibility of the A-grade thermal insulation material.

[0003] In the prior art, when the non-combustibility of the thermal insulation material is detected, the thermal insulation material needs to be placed in a cage. Since the temperature of the building material non-combustion test furnace is high, the cage needs to be hung directly above the building material non-combustion test furnace for non-combustibility detection. Usually, the cage is hung on a vertical suspender, and the suspender is fixed on a cross arm, and the cross arm is arranged on the support rods on both sides of the furnace body. When the thermal insulation material in the cage needs to be replaced, the two ends of the cross arm need to be released on the support rods, and then the cross arm is pulled upwards. The cross arm moves upwards, drives the suspender to move vertically upwards, and then drives the cage to move vertically upwards, so that the cage is away from the combustion port of the test furnace. After the thermal insulation material is replaced, the cage is hung on the suspender again. Since the hook body on the suspender is fixed, when the hook on the cage is connected with the hook body on the suspender, the hook on the cage needs to be aligned with the hook body on the suspender to ensure the stability of the cage.

[0004] When the thermal insulation material is replaced, the cross arm needs to be released to move upwards, and the hook on the cage is not easy to align with the hook body on the suspender.
