In addition, elastic connection spare 3 sets up respectively in four right angles departments of objective table 2 and base 1 for elastic connection spare 3 can guarantee the homogeneity of objective table 2 vibration, avoids appearing the concrete test block on objective table 2 and takes place to the circumstances of certain direction skew in the vibration process, has guaranteed the vibrations effect of concrete shaking table effectively.

As shown in fig. 1, a retractable limiting device 5 is disposed on the object stage 2, the retractable limiting device 5 includes two parallel first telescopic structures 51 and two parallel second telescopic structures 52, the first telescopic structures 51 and the second telescopic structures 52 are perpendicular to each other, and the first telescopic structures 51 and the second telescopic structures 52 can be extended and retracted in the vertical direction relative to the object stage 2.

The technical personnel in the field can understand that, through set up retractable stop device 5 on objective table 2 to make retractable stop device 5 can stretch out and draw back from top to bottom for objective table 2 is gone up in vertical direction, make when placing the concrete test block on objective table 2, the user can carry out the adaptability according to the high spacing height to retractable stop device 5 of the focus of concrete test block and adjust, avoids the phenomenon that the concrete test block takes place the slope in the vibration process.

As a preferred embodiment, as shown in fig. 1, the first and second

telescopic structures

51 and 52 include two telescopic rods 511 vertically disposed on the object stage 2 and a connecting rod 512 connecting top ends of the two telescopic rods 511. When a concrete test block is placed on the object stage 2, the user can adjust the telescopic heights of the two telescopic rods 511 by holding the connecting rod 512, so that the telescopic rods 511 can support the connecting rod 512 and fix the connecting rod 512 near the center of gravity of the concrete test block. For example, when the height of the concrete test block placed on the object stage 2 is high, the user raises the connecting rod 512, so that the telescopic rod 511 connected with the connecting rod 512 is correspondingly raised, and the connecting rod 512 can be supported, and the connecting rod 512 can reach the height of the center of gravity of the concrete test block, therefore, when the concrete vibration table is used for vibration test, the concrete test block cannot incline or even fall due to unstable center of gravity; correspondingly, when the height of the concrete test block placed on the object stage 2 is low, the user presses the bottom connecting rod 512, so that the telescopic rod 511 connected with the connecting rod 512 is correspondingly pressed down, and the connecting rod 512 can reach the gravity height of the concrete test block, and the function is the same as that described above, and is not described again.

As shown in fig. 2, the outer surface of the connecting rod 512 has a flexible coating 513, and it can be understood by those skilled in the art that by providing the flexible coating 513 on the outer surface of the connecting rod 512, when the concrete vibration table is used for vibration testing of a concrete test block, the flexible coating 513 can convert rigid impact between the connecting rod 512 and the concrete test block into flexible impact, and avoid a large amount of debris generated by the concrete test block during collision with the connecting rod 512.

It should be noted that the two first telescopic structures 51 having the same maximum telescopic height only means that the two first telescopic structures 51 can reach the same telescopic height, and does not mean that the two first telescopic structures 51 can only be maintained at the same height. The two first telescopic structures 51 can be respectively telescopic to different heights, but both the two first telescopic structures 51 are simultaneously higher than any one second telescopic structure 52.

It can be understood by those skilled in the art that by providing the first and second

telescopic structures

51 and 52 in the above manner, the two first and second

telescopic structures

As shown in fig. 1 and 4, the upper surface of the object stage 2 is provided with a slide rail 21, the bottom of the telescopic rod 511 is provided with a slide block 514, and the slide block 514 can move in the slide rail 21, so that the first telescopic structure 51 and the second telescopic structure 52 can move to different positions.

It can be understood by those skilled in the art that the first telescopic structure 51 and the second telescopic structure 52 are configured to be horizontally movable relative to the object stage 2, so that the first telescopic structure 51 and the second telescopic structure 52 can be moved to different positions on the object stage 2, and when concrete test blocks with different widths or lengths are placed on the object stage 2, a user can make the telescopic limiting device 5 tightly abut against the concrete test block by moving the first telescopic structure 51 and the second telescopic structure 52. Therefore, the telescopic limiting device 5 can limit the positions of the concrete test blocks with different cross sections, and the universality of the concrete vibrating table is further improved.

As shown in fig. 4, a through hole 211 is provided on the outer side surface of the slide rail 21, a groove 515 corresponding to the through hole 211 is provided on the outer surface of the slider 514, and the slide rail 21 and the slider 514 can be fixed by inserting the plug 6 into the through hole 211 and the groove 515.

It can be understood by those skilled in the art that, when the sliding block 514 moves to a certain position in the sliding rail 21, the through hole 211 on the sliding rail 21 corresponds to the position of the groove 515 on the sliding block 514, and a user inserts the plug-in unit 6 into the through hole 211 and abuts against the groove 515 on the sliding block 514, so that the sliding block 514 is limited to a fixed position on the sliding rail 21 by the plug-in unit 6, and the phenomenon that the sliding block 514 moves irregularly relative to the sliding rail 21 and the telescopic limiting device cannot tightly clamp a concrete test block during vibration of the concrete vibrating table is avoided.
