[0030] like Figures 1 to 5 As shown, the heat insulation cover inspection device 100 of this utility model is used to inspect heat insulation covers. The heat insulation cover inspection device 100 includes a base plate 1, a controller 2, a heat insulation cover support assembly 3, an impact inspection assembly 4, a temperature inspection assembly 5, and a movement drive assembly 6.

[0031] The heat insulation cover support assembly 3, the impact testing assembly 4, and the temperature testing assembly 5 are all mounted on the base plate 1, and the base plate 1 is provided with a sliding groove 11.

[0032] like Figure 2 As shown, the mobile drive assembly 6 includes a drive motor 61, a lead screw 62 connected to the drive motor 61, a guide rod 63 spaced apart from the lead screw 62, and a mounting bracket 64 fixed on the base plate 1 to support the drive motor 61. The lead screw 62 and the guide rod 63 are respectively disposed in the slide groove 11.

[0033] The heat insulation cover support assembly 3 is fixed on the lead screw 62, and the drive motor 61 drives the heat insulation cover support assembly 3 to move to the impact testing assembly 4 and the temperature testing assembly 5.

[0034] In this embodiment, the mounting bracket 64 is disposed at one end of the base plate 1 along the X direction, and the lead screw 62 and the guide rod 63 both extend along the X direction, that is, the axis of the guide rod 63 is parallel to the axis of the lead screw 62.

[0035] The controller 2 is electrically connected to the heat shield support assembly 3, the impact testing assembly 4, the temperature testing assembly 5, and the movement drive assembly 6. In this embodiment, the controller 2 is equipped with a display screen to display information such as temperature.

[0036] like Figure 3 As shown, the heat insulation cover support assembly 3 includes a support plate 31, a support frame 32 for supporting the support plate 31, at least two clamping plates 33 fixed on the support plate 31 and located above the support plate 31, and a first drive assembly 34 for driving the clamping plates 33 to move up and down.

[0037] The support plate 31 is used to place the heat insulation cover, and the clamping plate 33 is used to fix the heat insulation cover on the support plate 31 in the vertical direction. The first driving component 34 drives the clamping plate 33 to move up and down so that the clamping plate 33 fixes the heat insulation cover.

[0038] The support frame 32 is slidably disposed relative to the guide rod 63, and the support frame 32 is threadedly connected to the lead screw 62. In this embodiment, the bottom of the support frame 32 is provided with two lugs 321 protruding into the slide groove 11. One lug 321 has a through hole for the guide rod 63 to pass through, and the other lug 321 has a threaded hole for threaded connection with the lead screw 62. When the drive motor 61 is working, it drives the lead screw 62 to rotate, thereby driving the support frame 32 to move in the X direction, and the guide rod 63 plays a guiding role.

[0039] In this embodiment, the heat insulation cover support assembly 3 is provided with two clamping plates 33 to limit the heat insulation cover from both ends in the Y direction. In other embodiments, the number of clamping plates 33 may be four or more, which can limit the heat insulation cover from both the X and Y directions to achieve a better limiting effect and avoid misalignment during subsequent impact testing.

[0040] The first drive assembly 34 includes a first electric push rod 341 fixed on the support plate 31, a first connecting rod 342 connecting the first electric push rod 341 and the clamping plate 33, and a slide rod 343 disposed on the support plate 31 and extending in the vertical direction. The first electric push rod 341 is used to drive the first connecting rod 342 and the clamping plate 33 to move in the vertical direction, and the clamping plate 33 moves in the vertical direction.

[0041] Each clamping plate 33 is provided with two slide rods 343, and the first electric push rod 341 is located between the two slide rods 343.

[0042] like Figure 4As shown, the impact testing assembly 4 includes an impactor 41, a hydraulic cylinder 42 for driving the impactor 41 to move up and down, a hydraulic cylinder 42 connecting the hydraulic cylinder 42 and the impactor 41, and a second drive assembly 44 for driving the hydraulic cylinder 42 and the impactor 41 to move in the horizontal direction.

[0043] The second drive assembly 44 includes a slide rail frame 441, a second electric push rod 442 disposed on the slide rail frame 441, a second connecting rod 443 connected to the second electric push rod 442, and a sliding block 444 disposed on the second connecting rod 443. The sliding block 444 is connected to the hydraulic cylinder 42.

[0044] The slide rail frame 441 is fixed on the base plate 1 and extends upward. The top of the slide rail frame 441 extends along the Y direction. The second electric push rod 442 is used to push the second connecting rod 443 and the sliding block 444 to move along the Y direction, thereby driving the hydraulic cylinder 42 and the impactor 41 to move along the Y direction. When the heat insulation cover support assembly 3 drives the heat insulation cover to move below the impact testing assembly 4, the second drive assembly 44 drives the hydraulic cylinder 42 and the impactor 41 to move to a suitable position along the Y direction. Then, the hydraulic cylinder 42 is started to drive the hydraulic cylinder 42 and the impactor 41 to rise and fall, impacting the heat insulation cover, thereby testing the impact resistance of the heat insulation cover and detecting whether there are loose fixing points or structural cracks in the heat insulation cover.

[0045] like Figure 5 As shown, the temperature testing assembly 5 includes a testing box 51 with a horizontal opening for the heat insulation cover support assembly 3 to enter, a heating element 52 disposed in the testing box 51, a temperature sensor 53 disposed in the testing box 51, a reinforcing frame 54 fixed to the testing box 51, a third electric push rod 55 fixed to the reinforcing frame 54, and a fourth connecting rod 56 connecting the third electric push rod 55 and the heating element 52.

[0046] In this embodiment, the reinforcing frame 54 is fixed to the top of the testing box 51, the fourth connecting rod 56 protrudes into the testing box 51, and the third electric push rod 55 is used to drive the fourth connecting rod 56 and the heating element 52 to move up and down. When it is necessary to detect the temperature of the heat insulation cover, the heat insulation cover will be moved into the testing box 51. Then, the third electric push rod 55 drives the fourth connecting rod 56 and the heating element 52 to descend, so that the heating element 52 is close to the heat insulation cover. Then, the heat generated by the heating element 52 will perform temperature detection on the heat insulation cover. The temperature sensor 53 will detect the temperature of the heat insulation cover, thereby recording the temperature change or limiting the heat generated by the heating element 52. The temperature data will be displayed on the display screen of the controller 2. After the heat insulation cover detection is completed, the lead screw 62 will drive the support frame 32 and the heat insulation cover to move away from the interior of the heating testing box 51.

[0047] The heat insulation cover inspection device 100 of this utility model, by setting an impact inspection component 4 and a temperature inspection component 5, can perform impact and temperature inspections on the heat insulation cover, thereby increasing the impact resistance test of the heat insulation cover and detecting whether there are loose fixing points or structural cracks in the heat insulation cover; by setting a heat insulation cover support component 3, especially a clamping plate 33, the position of the heat insulation cover can be limited to prevent the heat insulation cover from shifting during inspection.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
