[0031] See Figure 1-2 , where Figure 1 and Figure 2 are respectively the front view and the top view of the ablation test device. An ablation test device provided in this embodiment includes:

[0032] Installation platform 1;

[0033] Spray gun mechanism 2, the spray gun mechanism 2 is arranged on the installation platform 1;

[0036] It can be understood that the installation platform 1 is mainly the basic support structure of the device. It can adopt a conventional design structure, or it can be the ground or other working surfaces. Other components can also be arranged on the working surface, and no further introduction will be made here. Those skilled in the art can understand and implement it in combination with the drawings in this embodiment and the function of the installation platform 1.

[0037] It can be understood that the spray gun mechanism 2 is commonly used in the material ablation test. Its main function is to spray flames to ablate the material to be tested, so as to test the ablation resistance of the material.

[0038] It can be understood that in this embodiment, the reciprocating movement component 3 can drive the test material on the ablation rack component 4 to move, changing its position relative to the spray gun mechanism 2, thereby changing the ablation position of the test; the reciprocating movement component 3 can drive the test material on the ablation rack component 4 to move back and forth relative to the flame ejected by the spray gun, thereby simulating the change of ablation frequency, and ablating back and forth between intermittent high and low temperatures to test complex working conditions; the reciprocating movement component 3 can regularly drive the test material on the ablation rack component 4 to approach or move away from the flame ejected by the spray gun, thereby controlling the ablation time; and it can also change the distance between the test material and the flame of the spray gun mechanism 2, thereby controlling the ablation temperature.

[0039] In the embodiment of the present utility model, the reciprocating movement component 3 includes a lateral movement mechanism 31 and a longitudinal movement mechanism 32. The longitudinal movement mechanism 32 can adjust the distance between the ablation rack component 4 and the spray gun mechanism 2. The lateral movement mechanism 31 can reciprocate laterally, and the ablation rack component 4 can change the ablation position and / or ablation time and / or ablation frequency under the lateral reciprocating movement of the lateral movement mechanism 31.

[0040] It can be understood that the reciprocating movement component 3 can move in the lateral, longitudinal, up-and-down, zigzag, regular curve, irregular curve directions, etc. Those skilled in the art can design according to actual needs. In the embodiment of this application, a combination of common lateral movement and longitudinal movement is preferably recommended. Specifically, the lateral movement mechanism 31 is used to achieve reciprocating movement, thereby realizing the adjustment of the position, residence time, frequency, etc. between the test material and the flame of the spray gun mechanism 2 to simulate complex working conditions. For example, the lateral movement mechanism 31 drives the test material to leave the flame area and locate at the flame point, while the longitudinal movement mechanism 32 can adjust the distance between the test material and the flame of the spray gun mechanism 2 to control the flame point temperature during ablation.

[0041] In the embodiment of the present utility model, the longitudinal movement mechanism 32 is arranged on the installation platform 1, the lateral movement mechanism 31 is arranged on the longitudinal movement mechanism 32, and the ablation rack component 4 is arranged on the lateral movement mechanism 31.

[0042] It can be understood that, such as Figure 1 and Figure 2As shown, in this embodiment, the longitudinal movement mechanism 32 of the reciprocating movement assembly 3 is disposed on the mounting platform 1, and the lateral movement mechanism 31 drives the ablation frame assembly 4 to reciprocate; in other embodiments, it is also possible that the lateral movement mechanism 31 is disposed on the mounting platform 1, the longitudinal movement mechanism 32 is disposed on the lateral movement mechanism 31, the ablation frame assembly 4 is disposed on the lateral movement mechanism 31, and the lateral movement mechanism 31 drives the longitudinal movement mechanism 32 and the ablation frame assembly 4 to reciprocate together. Those skilled in the art can adjust the specific setting relationship of the reciprocating movement assembly 3 according to actual needs, and no detailed description will be given here.

[0043] In the embodiment of the present invention, the driving modes of the lateral movement mechanism 31 include but are not limited to cylinder reciprocating drive, connecting rod reciprocating drive, and eccentric wheel reciprocating drive.

[0044] As Figure 2 shown, in this embodiment, the lateral movement mechanism 31 and the longitudinal movement mechanism 32 mainly use a cylinder to drive a slider to move along a slide rail. In other embodiments, those skilled in the art can select other conventional linear movement mechanisms according to actual needs. For example, the lateral movement mechanism 31 can use a connecting rod mechanism combined with the rotation of a motor to drive reciprocating movement, or it can also use an eccentric wheel combined with the drive rotation of a motor to drive the slider to reciprocate along the guide rail. Those skilled in the art can understand and implement the above possible methods according to actual needs in combination with the description and existing conventional technical means, and no further description will be given here.

[0045] In the embodiment of the present invention, as Figures 3 to 4 shown, Figures 3 to 4 are respectively the front view and top view of the ablation frame assembly provided in this embodiment. The ablation frame assembly 4 includes a bracket 41, a mounting member 42, and a fixing member 43. The bracket 41 is disposed on the reciprocating movement assembly 3, the mounting member 42 is disposed on the bracket 41, the fixing member 43 is detachably mounted on the mounting member 42, and the fixing member 43 is used to fix the material to be tested.

[0046] It can be understood that, as Figure 3 shown, the bracket 41 includes a base 411, a support rod 412, and a locking mechanism 413. The support rod 412 is adjustably disposed in the fixing hole on the base 411, and the mounting member 42 is disposed on the top of the support rod 412. The height of the mounting member 42 can be adjusted by adjusting the depth of the support rod 412 inserted into the fixing hole of the base 411, and then the height position is locked by the locking mechanism 413. The locking mechanism 413 can be a threaded member screwed in or other conventional methods, and no further detailed description will be given here, so as to realize adjusting the height position of the material to be tested fixed on the fixing member 43 relative to the spray gun mechanism 2, facilitating alignment with the flame point of the flame ejected by the spray gun mechanism 2.

[0047] In the embodiment of the present utility model, as Figure 3 shown in the figure, an installation hole 421 is provided on the installation member 42, and one end of the fixing member 43 can be inserted into the installation hole 421 for fixing; a groove 431 is provided on the fixing member 43, and the groove 431 is used for fixing the material to be tested.

[0048] It can be understood that, in order to facilitate the assembly of the material to be tested, in this embodiment, by simply providing a groove 431 for placing the material to be tested on the fixing member 43, and then inserting the fixing member 43 into the installation hole 421 on the installation member 42, the use and operation of the experimental device can be simply and quickly realized, improving the efficiency and convenience of the test; at the same time, in order to further ensure the installation and fixing effect, a tight fit can be adopted between the material to be tested and the groove 431, and between the fixing member 43 and the installation hole 421 to ensure the fixing effect. Those skilled in the art can understand and implement according to the actual situation, and will not be further described here. Further, the fixing member 43 is provided with a stepped structure to facilitate quick insertion into the installation hole 421 and at the same time be able to perform positioning and abutment. Similarly, the groove 431 can also be provided with a simple stepped structure to facilitate the fixing and installation of the material to be tested. More details will not be further described here, and those skilled in the art can adjust and deform according to actual needs.

[0049] In the embodiment of the present utility model, as Figure 5 shown in the figure, it is a schematic diagram of the main structure of the installation member in this embodiment. A cooling cavity 422 is provided inside the installation member 42, and a water inlet 423 and a water outlet 424 are provided on the installation member 42. The water inlet 423 and the water outlet 424 can be respectively connected to a water inlet pipe 5 and a water outlet pipe 6.

[0050] It can be understood that Figure 5 in order to facilitate intuitive understanding, the front end cover of the installation member 42 is removed in the figure. Those skilled in the art can add a front end cover to form an internally sealed cooling cavity 422 in the installation member 42, which will not be further described here specifically.

[0051] In the embodiment of the utility model, a control module is also included, and the control module is used to control the movement of the spray gun mechanism 2 and the reciprocating assembly 3. The control module may include conventional control components such as a PLC control unit, a touch screen, and a time relay. The process parameters such as ablation residence time, reciprocating frequency, and reciprocating number of times are set through the touch screen, and then the PLC is used to control the time and number of movements of the reciprocating assembly 3 according to the process parameters. Through rapid reciprocating motion, short-term high-frequency ablation and thermal shock of the flame on the surface of the test material can be achieved, simulating a complex working environment. Since the components of the control module belong to conventional electronic components in this field, the structure is not illustrated here. Those skilled in the art can select electronic components that can realize the above functions from the field in combination with the above description for setting.

[0052] In an embodiment of the utility model, a temperature measuring device is also included, and the temperature measuring device is used to measure the temperature of the ablation position. The specific temperature measuring device can adopt infrared temperature measurement or thermistor temperature measurement and thermal imaging temperature measurement, etc. Specifically, after adjusting the reciprocating component 3 to the specified position, an initial ablation test is performed, and the temperature is measured by the temperature measuring device to determine whether the temperature meets the requirements, and then the distance of the flame from the surface of the material to be tested is determined. During the ablation process, the ablation temperature can also be accurately controlled and monitored in combination with infrared temperature measurement, so as to accurately observe the test effect. Specifically, for example, by adopting infrared temperature measurement, a set of temperature measuring devices can be separately set on the mounting platform 1, and the temperature can be measured by aligning the ablation position. Similarly, since the components of the temperature measuring device belong to conventional parts in this field, the structure is not illustrated here. Those skilled in the art can select parts that can realize the above functions from the field in combination with the above description for setting.

[0053] In the embodiment of the present utility model, Figure 1 As shown in the figure, the spray gun mechanism 2 includes a spray gun 21 and a baffle 22. The spray gun 21 is set on the mounting platform 1 through a bracket, and the baffle 22 is set at the flame outlet of the spray gun 21. The baffle is convenient for preventing the temperature from drifting back and causing damage to the pipeline on the rear side of the spray gun 21.

[0054] Working process and principle of the ablation test device of the utility model:

[0055] First, fix the material to be tested on the groove 431 of the fixture 43 of the ablation rack assembly 4. Then insert the fixture 43 into the mounting hole 421 of the mounting part 42 for fixation. Then, by adjusting the support bracket 41 and the longitudinal movement mechanism 32, combine with the temperature measuring device to measure the distance to reach the set temperature, and at the same time align the material to be tested with the spray gun. Then set the ablation process parameters through the control module and start the ablation test. During the experiment, the ablation position, ablation time, ablation frequency, etc. are changed by controlling the reciprocating movement of the transverse movement mechanism 31 back and forth, and at the same time, the temperature situation during the ablation process is monitored through the testing device.

[0056] Due to the adoption of the above technical solution, the present utility model has at least the following beneficial effects:

[0057] The ablation test device provided by the present utility model combines the reciprocating movement assembly 3 with the ablation rack assembly 4.

[0058] Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art.
