[0001] The utility model relates to the technical field of compression performance testing equipment, in particular to a compression performance testing device for thermal insulation materials. Background Art

[0002] The insulation materials will be subjected to corresponding compressive performance tests before leaving the factory and before use. The compressive performance testing device will be used to perform compression tests on regular insulation materials to ensure that the compressive performance of the insulation materials meets the use requirements.

[0003] After the compressive performance testing device completes the test on an insulation material, the tested insulation material needs to be taken out first before the next insulation material can be placed, and the test process for the next insulation material can be restarted. This results in a long time to complete the switching of the next untested insulation material, and a long time to prepare for the insulation material test. Especially when the number of test materials is large, the test time is further extended. There is still much room for improvement in the test efficiency of the compressive performance test of insulation materials. Summary of the invention

The test base moves in a circular direction with the test turntable to switch between tested and untested thermal insulation materials, eliminating the need to remove the tested thermal insulation material before proceeding to the inspection and replacement process of the next thermal insulation material. The next untested thermal insulation material can be switched during the test of the thermal insulation material, thereby improving the test switching speed and shortening the test preparation time.

[0030] The utility model proposes a device for testing the compressive performance of thermal insulation materials, comprising: a main compressive test frame 1, a test turntable 2 and a test base 3, an electric lifting screw 101 is rotated on the upper part of the main compressive test frame 1, a lifting test frame 102 is screwed to the electric lifting screw 101, a pressure sensing module 103 is fixed at the bottom of the lifting test frame 102, a lower test pressing block 104 is fixed at the bottom of the pressure sensing module 103, an upper outer protective tube 105 is slidably arranged on the outer side of the lower test pressing block 104, the lifting test frame 102 is vertically slidably connected to the main compressive test frame 1, a test base 3 is arranged vertically below the lower test pressing block 104, and the external thread of the electric lifting screw 101 guides the lifting test frame 102 to move forward. Axial movement is carried out, and the lifting test frame 102, the pressure sensing module 103, and the lower test pressure block 104 are synchronously lowered, and the lower test pressure block 104 and the insulation material inside the inner convex ring platform 301 are pressure tested. The lower part of the main compression test frame 1 is rotatably provided with a test turntable 2, and the top of the test turntable 2 is provided with a sliding side limit block 201 in an annular array, and the tail of the side limit block 201 is fixed with a tail support spring 202, and the tail end of the tail support spring 202 is fixedly connected to the test turntable 2, and the top of the test turntable 2 is provided with a test base 3 in an annular array, and the top of the test base 3 is provided with a ring-shaped convex inner convex ring platform 301, and the upper part of the test base 3 is slidably inserted with a lower protective tube 302 on the outer side of the inner convex ring platform 301.

[0031] In the disclosed embodiment, the side limit block 201 is slidably engaged with the outer groove of the test base 3, and the test base 3 is horizontally slidably connected with the top slot of the test turntable 2. The test base 3 moves circumferentially with the test turntable 2 to switch between tested and untested insulation materials, thereby eliminating the need to remove the tested insulation material before the next untested insulation material can be replaced. During the test of the insulation material, the next untested insulation material can be switched by rotating, thereby improving the speed of test switching and shortening the test preparation time.

[0032] In the disclosed embodiment, the length and width of the lower protective tube 302 are both smaller than the upper outer protective tube 105. When the upper outer protective tube 105 and the lower protective tube 302 overlap, the lower protective tube 302 is located on the inner side of the upper outer protective tube 105. The upper outer protective tube 105 and the lower protective tube 302 overlap to seal the outside of the thermal insulation material, thereby preventing the thermal insulation material from being damaged by the test and flying around, thereby reducing the cleaning burden.

[0033] In the embodiment of the present disclosure, when the side limit block 201 and the outer groove of the test base 3 are slidably engaged, the test base 3 is in a fixed state, and the side limit block 201 and the test base 3 are separated by pulling outward, the test base 3 and the test turntable 2 are separated, and the test base 3 is replaced or inverted to clean the damaged insulation material.

[0034] Embodiment 2, on the basis of embodiment 1, the test turntable 2 is provided with a groove at the corresponding bottom of each test base 3, and a tail support spring 202 is provided to support the side limit block 201 and the groove of the test turntable 2 to slide and engage, the top of the side limit block 201 is an arc structure, and the side limit block 201 limits the rotation angle of the test turntable 2. When there are four test bases 3, the test turntable 2 will engage the side limit block 201 when it rotates ninety degrees, eliminating the need to align the lower test pressure block 104 with the test base 3 below, making it more convenient to use.

[0035] The working principle of this embodiment is as follows: the cut square insulation material is placed on the inner side of the inner convex ring platform 301, the test base 3 is placed on the inner side of the inner convex ring platform 301 for the insulation material to be tested, the test base 3 and the lower test block 104 can be replaced according to the size of the insulation material, the motor drives the electric lifting screw 101 to rotate, the external thread of the electric lifting screw 101 guides the lifting test frame 102 to move axially, the lifting test frame 102 and the pressure sensing module 103 and the lower test block 104 descend synchronously, the lower test block 104 contacts the insulation material on the inner side of the inner convex ring platform 301, the pressure sensing module 103 tests the pressure data, and when the test of one insulation material is completed, the lifting test frame 102 and the pressure sensing module 103, and the lower test pressing block 104 are synchronously moved upward and away from the thermal insulation material, and the test turntable 2 rotates in a circular direction. The test base 3 switches between the tested and untested thermal insulation materials along with the circumferential movement of the test turntable 2, eliminating the need to take down the tested thermal insulation material before the next untested thermal insulation material can be replaced. In the test of the thermal insulation material, the next untested thermal insulation material can be quickly switched in advance, which improves the test speed, shortens the test time, and further improves the test work efficiency. The test base 3 and the test turntable 2 are separated by pulling the side limit block 201 outward and separating the test base 3, and the test base 3 is inverted to pour out and clean the damaged thermal insulation material;

[0036] During the test, the upper outer protective tube 105 descends to the outside of the lower protective tube 302, and the upper outer protective tube 105 and the lower protective tube 302 overlap to seal the outside of the thermal insulation material. The lower protective tube 302 and the upper outer protective tube 105 surround the outside of the thermal insulation material to prevent the thermal insulation material from being damaged by the test and flying around. When the height of the thermal insulation material is low, the lower protective tube 302 and the upper outer protective tube 105 can be staggered inside and outside to adapt to the thermal insulation material of lower height. The upper outer protective tube 105 moves vertically and staggered along the lower test block 104 to adapt to the thermal insulation material of lower height, thereby increasing the coverage effect and compatibility with thermal insulation materials of different test thicknesses and improving the user experience.
