[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] As Figures 1-4 shown, a stone specimen bearing device includes a carrier frame 1 for placing stone specimens. Corresponding positioning grooves 11 are provided on the opposite side frames of the carrier frame 1, and a bearing rod 12 for supporting the stone specimens is arranged in the positioning grooves 11 on the opposite side frames. The spacing of the positioning grooves 11 is set corresponding to the volume of the specimen, so that the stone specimens supported on the bearing rod 12 can be placed at a predetermined interval. When in use, first place the bearing rod 12 in the corresponding positioning groove 11 according to the volume of the specimen, then place the stone specimen on the adjacent bearing rods 12 to complete the positioning placement of the stone specimen, and then put the carrier frame 1 carrying the stone specimen into the water absorption tester to start the relevant test.

[0023] In this embodiment, the spaced bearing rods 12 can keep the stone specimens at a fixed interval to meet the specimen interval requirements, avoid the problem of unstable placement of stone specimens when using a traditional carrier, and ensure the accuracy of test data. At the same time, in this embodiment, according to the volume of different specimens, the bearing rod 12 can be adjusted to be lapped in the corresponding positioning groove 11, so as to position and place stone specimens of different volumes, improving the applicability.

[0024] As a preferred embodiment, the bearing rod 12 is of a cylindrical structure to reduce the contact area between the bearing rod 12 and the stone specimen, and minimize the influence of the bearing rod 12 on the test data. More preferably, the bearing rod 12 is made of a transparent material such as a glass rod or acrylic, which is convenient for the test personnel to view the contact situation between the stone specimen and the bearing rod 12.

[0025] Preferably, a scale ruler 13 is provided on the carrier frame 1 corresponding to the positioning groove 11, which is used for the test personnel to view the accurate dimension spacing at any time, facilitating the quick adjustment of the placement position of the bearing rod 12 and improving the operation efficiency.

[0026] Preferably, in order to strengthen the structural strength of the carrier frame 1, as Figure 2 shown, a reinforcing longitudinal beam 14 is connected between the opposite side frames of the carrier frame 1 to ensure the structural rigidity of the carrier frame 1 and increase the bearing stability of the stone specimen.

[0027] In a further embodiment, as Figures 3-4As shown, the loading frame 1 can be arranged in layers to increase the loading capacity and meet the test requirements of more stone specimens. Specifically, the upper end face of the frame of the loading frame 1 is provided with a socket sleeve 15, and the lower end face of the frame of the adjacent-layer loading frame 1 is provided with a socket pin 16 corresponding to the socket sleeve 15. The adjacent-layer loading frames 1 are in plug-in fit through the socket pin 16 and the socket sleeve 15 to form a loading rack body with a vertical-layer structure. When there are many stone specimens to be tested, first load the first-layer loading frame 1, then insert the second-layer loading frame 1 into the socket sleeve 15 of the first-layer loading frame 1 through the socket pin 16, and then load the second-layer loading frame 1 until the loading of the planned specimen quantity is completed. This embodiment greatly expands the loading capacity of the stone specimens and further improves the test efficiency.

[0028] Further, a locking set screw 17 is provided on the socket sleeve 15 corresponding to the socket pin 16 for locking the height of the socket pin 16 in the socket sleeve 15. The locking set screw 17 is screwed through the tube wall of the socket sleeve 15 and can be tightened against the socket pin 16. By adjusting the lifting height of the socket pin 16, the loading requirements of stone specimens of different volumes can be met.

[0029] Further, for the convenience of taking and placing the loading frame 1, as Figure 2 shown, a handle 18 is provided on the loading frame 1 to facilitate the tester to hold and take and place it.

[0030] The specific embodiments of the present utility model disclosed above are only for illustration, but the present utility model is not limited thereto. For those of ordinary skill in the art, any modifications made without departing from the principle of the present utility model should be regarded as belonging to the protection scope of the present utility model.
