Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire prevention testing, in particular to a device for multi-point testing of a composite A-grade EPS flame retardant fireproof board. Background Art
[0002] Class A EPS flame retardant fireproof board has excellent thermal insulation performance. By improving on the traditional molded polystyrene foam board and adding flame retardants, its fire resistance can be effectively improved to meet the Class A fireproof standard. Class A means that the material has high fire resistance and is not easy to burn. Flame retardant board can effectively prevent the spread of flames when a fire occurs, improving the overall fire safety of the building.
[0003] In traditional processes, the production quality inspection of flame-retardant fireproof board products is relatively rigid, and usually the flame-retardant fireproof board to be tested is directly flame-baked. This test method cannot fully evaluate the flame-retardant performance of the flame-retardant board as a whole, and it is also accompanied by uneven heating during the test process. It is difficult to simulate the different heat effects on different parts of the flame-retardant board in an actual fire, and the test results are inaccurate. Flame-baking only a part of the flame-retardant board cannot reflect the flame-retardant properties of the entire flame-retardant board, and may ignore the defects of other areas of the flame-retardant board.

[0024] like Figure 2 , 3 As shown, the flame spraying assembly 6 comprises: a body 601, a driving motor 602 is fixedly connected to one side of the body 601, an output end of the driving motor 602 passes through the body 601 and is fixedly connected to a gear 603, a rack 604 meshing with the gear 603 is provided at the top of the transverse guide column 5, and a flame sprayer 605 is fixedly connected to the other side of the body 601. The gear 603, the rack 604 and the driving motor 602 provide a good driving effect for the displacement of the flame spraying assembly 6, and the flame retardant and fireproof board to be tested can be tested in all directions.
[0025] like Figure 2 , 5 As shown in Figure 6, the bottom end of the flame-spraying assembly 6 is fixedly connected with a first slider 11, and the transverse guide column 5 is provided with a first slide groove for the first slider 11 to slide. The first slider 11 and the first slide groove provide a stable and reliable guiding effect for the flame-spraying assembly 6, so that the flame-retardant plate to be tested is heated evenly. Two second sliders 12 are fixedly connected to both sides of the transverse guide column 5, and the inner walls of the two first slots 3 are provided with a second slide groove for the second slider 12 to slide. The second slider 12, the second slide groove and the pushing motor 4 are conducive to adjusting and guiding the position of the transverse guide column 5.

[0027] Working principle: When the utility model is implemented, the flame retardant plate is first clamped by the clamping groove 13, and the screw at the output end of the rotating motor 8 is started to push the threaded fastener 9 forward and stop when it reaches the appropriate position. The flamethrower 605 and the drive motor 602 are started, and the output end drives the rotating gear 603 to move laterally on the rack 604. At the same time, the first slider 11 and the first slide groove provide a stable guiding effect for the flamethrower assembly 6, so that the surface of the flame retardant plate is evenly heated. The output ends of the two push motors 4 push the lateral guide column 5 up and down to change the height of the flamethrower assembly 6, and flexibly adjust the orientation of the flamethrower assembly 6 to prevent the situation where defects in other areas of the flame retardant plate are ignored. And according to the actual test requirements, the flame temperature of the flamethrower 605 can be changed to simulate different degrees of fire.
