Description

Technical Field

[0001] The utility model belongs to the technical field of indoor testing of highway engineering, and in particular relates to a flame retardant and smoke suppression performance testing instrument for asphalt materials. Background Art

[0002] Due to the relatively closed space in the tunnel and the flammability of asphalt materials, asphalt pavement tunnels are prone to fires when traffic accidents occur, and a large amount of toxic gases are produced. Therefore, asphalt materials are required to have good flame retardant and smoke suppression properties while meeting basic road performance. However, there are relatively few instruments in China that can test the flame retardant and smoke suppression properties of asphalt materials. The existing test methods such as the limiting oxygen index test and the vertical combustion test conditions are relatively ideal. However, the vertical combustion test has certain requirements for the installation position of the sample. In order to ensure the accuracy of the experiment, the traditional test instrument needs to repeatedly adjust the sample position when in use, which makes the operation cumbersome and the sample cannot be moved to the specified position quickly and accurately, which is inconvenient to use.

[0020] like Figure 1-5 As shown, an instrument for testing the flame retardant and smoke suppression performance of asphalt materials comprises a cabinet 1, a transparent cabinet door 2 is hingedly connected to the front side of the cabinet 1, a slide rail 3 facing forward and backward is installed on the lower side of the interior of the cabinet 1, a blowtorch 4 is slidably installed on the upper side of the slide rail 3, a control handle 5 slidably connected to the cabinet 1 is connected to the front side of the blowtorch 4, a horizontal slide bar 6 facing left and right is installed on the upper side of the interior of the cabinet 1, a slider 7 is slidably connected to the upper side of the horizontal slide bar 6, a vertical slide bar 8 is installed on the lower side of the slider 7, a clamping assembly is slidably connected to the upper side of the vertical slide bar 8, and a control mechanism for controlling the movement of the clamping assembly is installed on the upper side of the cabinet 1;

[0021] The control mechanism includes a first screw rod 9, which is rotatably connected to the cabinet 1 and threadedly connected to the slider 7. A horizontal knob 10 is rotatably installed on the side of the cabinet 1, and the horizontal knob 10 is transmission-connected to the first screw rod 9. A vertical control component for controlling the up and down movement of the clamping component is installed on the upper side of the cabinet 1, and a display component for displaying the position status of the clamping component is installed on the front side of the cabinet 1.

[0022] When the utility model is used, the material sample to be tested is fixed on the upper side of the clamping assembly, and the horizontal knob 10 is turned. The first screw rod 9 can move the slider 7 left and right, thereby driving the sample to move left and right. The vertical control assembly can conveniently control the clamping assembly to move up and down, thereby driving the position adjustment of the sample in the vertical direction. Then, the blowtorch 4 is ignited, and the control handle 5 can control the blowtorch 4 to move back and forth to test the sample. The display assembly can display the value corresponding to the position of the clamping assembly.

[0023] The cooperation between the first screw rod 9 and the slider 7 allows the left and right displacement of the sample to be adjusted by simply turning the horizontal knob 10, making the test instrument easy to operate. The vertical control component can quickly adjust the vertical position of the sample, and the display component can display the value corresponding to the position of the clamping component, so as to facilitate and accurately adjust the sample to the precise position, thereby improving the accuracy of the equipment test data and the convenience of equipment use.

[0024] The vertical control component includes a rotating shaft 11 which is rotatably connected to the cabinet 1 and faces left and right. Four limiting protrusions 12 are evenly installed on the outside of the rotating shaft 11. A gear sleeve 13 matching the rotating shaft 11 and the limiting protrusions 12 is installed on the upper side of the rotating shaft 11. The gear sleeve 13 is slidably connected to the limiting protrusions 12 left and right and is rotatably connected to the slider 7. A spur gear 14 meshing with the gear sleeve 13 is vertically rotatably installed on the side of the slider 7.

A vertical knob 18 transmission-connected to the rotating shaft 11 is rotatably installed on the side of the horizontal knob 10.

[0025] When the vertical control assembly is working, it only needs to rotate the vertical wheel. At this time, the shaft 11 drives the gear sleeve 13 to rotate, and under the action of the first bevel gear 15 and the second bevel gear 17, the second screw rod 16 is driven to rotate, thereby controlling the clamping assembly to move up and down.

[0026] The cooperation between the rotating shaft 11 and the gear sleeve 13 ensures that when the slider 7 is in any left or right position, the vertical rotating wheel can independently control the lifting and lowering of the clamping assembly. At the same time, the design of the vertical knob 18 arranged on the side of the horizontal knob 10 enables the staff to adjust the equipment more conveniently, avoiding the need for the staff to shift their attention or adjust their posture between multiple positions, thereby improving work efficiency.

[0027] The display assembly includes two transverse grooves 19, which are opened on the upper front side of the cabinet 1 and arranged up and down. A horizontal scale 20 is horizontally provided on the upper side of the transverse groove 19 on the lower side, and a vertical scale 21 is horizontally provided on the upper side of the transverse groove 19 on the upper side. Pointers 22 are slidably connected to the front sides of the two transverse grooves 19. A connecting rod 23 is fixed between the rear side of the pointer 22 on the lower side and the slider 7. Two sprockets 24 distributed on the left and right are rotatably installed on the rear side of the transverse groove 19. A third bevel gear 26 concentrically fixed with the rotating shaft 11 is rotatably installed on one side of the rotating shaft 11.

The fourth bevel gear 27 is transmission-connected to one of the sprockets 24. A chain 25 is transmission-connected between the two sprockets 24. The pointer 22 on the upper side is transmission-connected to the chain 25.

[0028] When the slider 7 moves left and right, the connecting rod 23 can make the pointer 22 indicate the corresponding scale on the horizontal scale 20, and the third bevel gear 26 and the fourth bevel gear 27 can link the rotating shaft 11 with the sprocket 24, so that when the clamping assembly moves up and down, the pointer 22 located on the upper side can indicate the corresponding value on the vertical scale 21, so that the staff can intuitively observe and debug the position of the sample, thereby improving the usability of the equipment.

[0029] A magnifying glass 28 is connected to the front side of the two pointers 22 .

[0030] The magnifying glass 28 can magnify the values ​​of the horizontal scale 20 and the vertical scale 21 in front of the pointer 22, which is convenient for the staff to observe and can further improve the accuracy of the sample position, thereby improving the accuracy of the experiment.

[0031] The clamping assembly includes a fixing plate 29 and a fixing clamp 30 .
