[0034] A plurality of racks 3 are provided, and the plurality of racks 3 are spaced apart from each other and arranged between two corresponding mobile platforms 21. The racks 3 include beams 32 arranged on both sides of the mobile platform 21, and the two beams 32 are arranged in parallel. A layer net 31 is set above the two beams 32 for placing concrete test blocks, and rectangular positioning holes 321 corresponding to the positioning blocks 211 on the mobile platform 21 are opened at both ends of each beam 32 for interlocking with the positioning blocks 211 to fix the beams 32.
[0035] When the cam 21 is in the upright position, the cam 21 is in the upright position, and the cam 21 is in the upright position, so that ...

When placing the concrete test block, the ribs of the layer net 31 can place the smaller concrete test block stably without closing the bottom of the concrete test block. By moving the partition component 4 between two adjacent concrete test blocks and unfolding the telescopic member 41, the telescopic member 41 is limited by the limiting member 42 to separate each concrete test block, forming multiple intervals that adapt to the size of the concrete test blocks, thereby avoiding accidental collision of the concrete test blocks and affecting the test quality of the concrete.
[0039] In one embodiment, the arrangement direction of the ribs on the layer of mesh 31 is perpendicular to the placement direction of the beams 32;
[0040] The telescopic member 41 includes a primary telescopic plate 411 slidably arranged in the storage rack 3, the top of the primary telescopic plate 411 is located below the layer net 31, and a secondary telescopic plate 412 is vertically slidably arranged in the primary telescopic plate 411, the top of the secondary telescopic plate 412 can slide upward out of the primary telescopic plate 411, and a third telescopic plate 413 is vertically slidably arranged on the secondary telescopic plate 412, and the top of the third telescopic plate 413 can slide upward out of the secondary telescopic plate 412.
[0041] With this design, when the telescopic member 41 is not in use, the secondary telescopic plate 412 and the tertiary telescopic plate 413 are both stored in the primary telescopic plate 411, and the primary telescopic plate 411 moves back and forth under the layer net 31, so it will not interfere with the staff's placement of concrete test blocks. The staff moves the primary telescopic plate 411 between the concrete test blocks and unfolds the secondary telescopic plate 412 and the tertiary telescopic plate 413 through the gaps between the grids of the layer net 31 to complete the separation between the concrete test blocks.
[0042] In one embodiment, the first telescopic plate 411 is provided with an inner cavity for the second telescopic plate 412 to slide vertically, and a limiting cavity 4112 is provided on the inner wall of the first telescopic plate 411, and limiting holes 4111 penetrating the inner cavity and the limiting cavity 4112 are provided at the tops of both ends of the inner cavity;
[0043] The limiting member 42 includes a third rotating rod 421 at one end which is rotatably arranged in the limiting cavity 4112, and the other end of the third rotating rod 421 extends to the outside of the primary telescopic plate 411, and an arc-shaped plate 422 is relatively arranged on one end of the third rotating rod 421 located in the limiting cavity 4112, and push rods 423 are respectively arranged on both sides of the limiting cavity 4112 corresponding to the third rotating rod 421, and each push rod 423 is provided with a pin block 424 at one end away from the third rotating rod 421, and one end of the pin block 424 is slidably inserted in the primary telescopic plate 411 through the limiting hole 4111, and a first elastic unit 425 is provided between the pin block 424 and the limiting cavity 4112, for pushing one end of the secondary telescopic plate 412 to move into the primary telescopic plate 411.

When the secondary telescopic plate 412 needs to be unfolded, the staff pulls up the secondary telescopic plate 412. When the bottom of the secondary telescopic plate 412 slides above the limiting hole 4111, the first elastic unit 425 is reset and drives the pin block 424 to slide toward the center direction of the secondary telescopic plate 412, so that the pin block 424 extends out of the limiting hole 4111 and abuts against the bottom end of the secondary telescopic plate 412, preventing the secondary telescopic plate 412 from being unfolded. 2 moves toward the inner cavity of the primary telescopic plate 411, at which time the secondary telescopic plate 412 is limited. When it is necessary to retract the secondary telescopic plate 412, the staff rotates the third rotating rod 421 and drives the arc plate 422 to rotate, so that the corresponding arc plate 422 contacts and pushes the corresponding push rod 423 away from the center direction of the secondary telescopic plate 412, and each push rod 423 drives the corresponding pin block 424 to slide away from the center direction of the secondary telescopic plate 412, so that the pin block 424 exits the limiting hole 4111 and is recovered into the limiting cavity 4112, the first elastic unit 425 is compressed, and the secondary telescopic plate 412 is reset.

[0047] The limiting component 42 also includes a limiting block 426 slidably arranged in the grooves on both sides of the third-level telescopic plate 413, and a second elastic unit 427 is arranged between the groove and the limiting block 426. The second elastic unit 427 is used to push one end of the limiting block 426 to extend out of the third-level telescopic plate 413 and limit the top of the secondary telescopic plate 412 to prevent the third-level telescopic plate 413 from moving into the interior of the secondary telescopic plate 412.
[0048] With this design, when the three-stage telescopic plate 413 is stored in the two-stage telescopic plate 412, each second elastic unit 427 is compressed and drives the corresponding limit block 426 to be stored in the groove. When the three-stage telescopic plate 413 needs to be unfolded, the staff pulls up the three-stage telescopic plate 413 until the limit block 426 is pulled out of the two-stage telescopic plate 412. At this time, the second elastic unit 427 is reset and drives the corresponding limit block 426 to overlap the top of the two-stage telescopic plate 412. When the three-stage telescopic plate 413 needs to be recovered, the staff presses down the three-stage telescopic plate 413 to compress the second elastic unit 427 and drive the corresponding limit block 426 to be stored in the corresponding groove, and the three-stage telescopic plate 413 is reset.
[0049] Preferably, the second elastic unit 427 can be a spring in the prior art.
[0050] It should be noted that the limiting block 426 and the top of the storage slot of the secondary telescopic plate 412 are rounded to make it easier for the limiting block 426 to extend from and be stored in the secondary telescopic plate 412 .
