[0021] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0022] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a vibration table with protective function, comprising:

[0024] The base plate 6 has multiple vibration springs 7 symmetrically arranged on its top surface along its circumference; the bottom of the base plate 6 is provided with walking wheels 5; the base plate 6 is provided with support feet 4 on both sides along its direction of movement, and the height of the support feet 4 from the ground is adjustable.

[0025] The box body 1 has an opening at the top and is positioned above the base plate 6. The bottom surface of the box body 1 is fixedly connected to each of the vibration springs 7. The box body 1 is equipped with a clamping device 3 for fixing the concrete mold. The bottom of the box body 1 is equipped with a vibration motor.

[0026] The protective cover 2 includes two opposing cover bodies 21, which are slidably connected to the box body 1. After sliding towards each other and docking, the two cover bodies 21 can cover the top opening of the box body 1, or slide relative to each other to expose the top opening of the box body 1.

[0027] In this technical solution, two support legs 4 are positioned on the front and rear sides of the base plate 6 along its walking direction. After the vibration table is moved to the test position by the bottom wheels 5, the height of the support legs 4 is adjusted so that they are supported on the ground, thereby ensuring the stability of the vibration table during the test. The housing 1 is supported on the base plate 6 by each of the vibration springs 7. The clamping device 3 fixes the concrete mold inside the housing 1, and then the vibration motor provides vibration force to the concrete specimen inside the housing 1 to ensure that the concrete inside the mold is compacted. During vibration, the two covers 21 slide towards each other until they are joined together, thereby covering the top opening of the housing 1 to prevent concrete from splashing out, thus avoiding injury to construction personnel and preventing the difficulty of cleaning up spilled concrete.

[0028] In another technical solution, the side wall of the housing 1 has corresponding grooves 24 for the two covers 21, and each cover 21 has a slider 22 fixedly mounted on it that can slide within the grooves 24. The slider 22 slides within the grooves 24, causing the cover 21 to slide relative to the housing 1. Figure 2 As shown, the slide groove 24 is formed along the sliding direction of the cover 21. Preferably, the slide groove 24 penetrates the side wall of the housing 1, and one end of the slider 22 passes through the slide groove 24 and extends into the housing 1, and is connected to a limiting block 23. The limiting block 23 restricts the movement of the cover 21 in a direction perpendicular to its sliding direction, further ensuring the stability of the cover 21 when sliding.

[0029] In another technical solution, the cover 21 is a transparent plastic cover. Grooves are formed on the opposite sides of the two covers 21. A magnet is fixedly installed in the groove of one cover 21, and an iron sheet is fixedly installed in the groove of the other cover 21. Construction personnel can observe the vibration test process in real time through the transparent cover 21. When the concrete level in the concrete mold drops, it can be replenished in time; when the concrete specimen cracks, adjustments can be made promptly. Due to the adsorption force of the magnet and the sheet, the two covers 21 can be firmly connected when they move towards each other and dock, without separating due to vibration. When it is necessary to separate the two covers 21, the construction personnel only need to apply force to overcome the adsorption force.

[0030] In another technical solution, such as Figure 3As shown, the clamping device 3 includes a pair of fixed plates 31, which are symmetrically fixed on two parallel inner walls inside the housing 1. Three telescopic rods are horizontally spaced along the length of each fixed plate 31. Each telescopic rod includes a sleeve 32, a sliding rod 33, and a fixing block 34. One end of the sliding rod 33 extends into the sleeve 32, and the other end is fixedly connected to the fixing block 34. The end of the sleeve 32 is fixedly connected to the fixed plate 31. A spring 35 is sleeved on the telescopic rod located in the middle of the fixed plate 31. One end of the spring 35 is fixedly connected to the fixed plate 31, and the other end is fixedly connected to the fixing block 34. The concrete mold is placed between the two fixed plates 31, causing the sliding rods 33 of each telescopic rod to slide into the sleeve 32, simultaneously compressing the spring 35. The rebound force of the spring 35 clamps the concrete mold, preventing displacement during vibration.

[0031] In another technical solution, such as Figure 4 As shown, the support leg 4 includes a support block 41, a screw 43, and a support plate 44. One end of the support block 41 is fixedly connected to the side wall of the base plate 6, and a vertically penetrating threaded hole is formed in its center. The screw 43 is threadedly connected to the threaded hole, and the support plate 44 is fixedly disposed at the bottom of the screw 43. Rotating the screw 43 can control the up and down movement of the support plate 44, thereby allowing the support plate 44 to be supported on the ground or lifted off the ground.

[0032] Furthermore, to facilitate the rotation of the screw 43, a handle 42 is provided on the top of the screw 43.

[0033] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
