Technical Field
[0001] This utility model relates to the field of concrete testing, specifically a vibration table for concrete testing. Background Technology
[0002] Concrete testing refers to methods that evaluate the properties and various conditions of concrete materials to obtain information such as the quality, strength, hardness, and durability of concrete. Its role in modern engineering construction is increasingly prominent, as performance indicators directly affect the quality of construction. By testing concrete, its actual performance can be accurately and effectively understood, and its comprehensive performance during construction can be comprehensively evaluated and analyzed. This provides a basis and reference for formulating and implementing specific quality management technical solutions, controlling construction quality from the source. To facilitate concrete testing, a vibration table is needed. The "Vibration Table for Concrete Testing" disclosed in application number "CN202121842333.0" is also an increasingly mature technology, which involves "starting the vibration motor, allowing the concrete on the test mold to pass through..." The concrete falls through the filter holes into the filter ring groove. The lifting assembly is then activated to lift one end of the worktable, moving the concrete in the filter ring groove towards the discharge port, and finally dropping it into the storage bin, thus facilitating cleaning after use. However, this vibration table has the following drawbacks: While the vibration motor does vibrate the concrete, its simple structure makes it difficult to fix concrete of different sizes as needed, potentially causing concrete to detach during testing. Therefore, it is necessary to provide a vibration table that allows for stable installation and fixing of concrete of different sizes, improving testing safety. Furthermore, the testing effect of this vibration table on concrete is not significant enough. Therefore, it is necessary to provide a vibration table that improves vibration testing effectiveness and enhances practicality. Utility Model Content

In use, concrete blocks of different sizes are first placed on the upper end of the anti-slip plate 104 on the receiving plate 101. Then, the pressure plate 105 is lowered so that the lower anti-slip plate 104 contacts the concrete block, thus initially enhancing the installation and fixing of concrete blocks of different sizes. Next, the anti-slip nut 107 is tightened and lowered, and the concrete block is squeezed and fixed in conjunction with the screw 102 and the pressure plate 105. Then, the servo motor 207 is started, rotating the transmission shaft 205, which in turn rotates the eccentric shaft 206, thereby causing the transmission plate 208, the hinge block 209, and the upper receiving plate 101 to vibrate. When the receiving plate 101 reciprocates, the presence of the vibration spring 203 improves the vibration testing effect on the concrete, thus enhancing the practicality of the vibration table.

[0019] In one specific embodiment, the positioning rod 103 is inserted into the positioning hole 122, thereby improving the stability of the installation and fixing of the concrete block by the pressure plate 105.
[0020] Please see Figure 2 - Figure 4 The upper end of the receiving plate 101 is provided with a circular groove 131, the anti-slip plate 104 is installed inside the circular groove 131, the side surface of the circular groove 131 is provided with a number of slots 132, and the side surface of the anti-slip plate 104 is fixedly connected with a number of clips 133, and the clips 133 are all clipped inside the slots 132.

[0022] Please see Figure 5 The upper end of the base 201 is fixedly connected to two supports 211, the drive shaft 205 is rotatably connected inside the two supports 211, and the upper end of the connecting shaft 204 is fixedly connected to a bolt 212, which is threaded into the inside of the receiving plate 101.
[0023] In one specific embodiment, the support 211 can improve the rotational connection stability of the drive shaft 205, and the bolt 212 threaded connection inside the bearing plate 101 can improve the connection strength between the connecting shaft 204 and the bearing plate 101.
[0024] Please see Figure 5 One end of the drive shaft 205 has a limiting hole 221, and the output end of the servo motor 207 is fixedly connected to the limiting shaft 222, which is inserted into the limiting hole 221.
[0025] In one specific embodiment, the limiting shaft 222 is inserted into the limiting hole 221. When the servo motor 207 rotates, it can drive the transmission shaft 205 to rotate, and then drive the transmission plate 208 to rotate for vibration testing.
[0026] Please see Figure 5 A fixing ring 231 is fixedly connected to the lower end of the transmission plate 208. A bearing 232 is installed inside the fixing ring 231, and the eccentric shaft 206 is inserted into the bearing 232.

[0028] Working principle: In use, concrete blocks of different sizes are first placed on the upper end of the anti-slip plate 104 on the receiving plate 101. Then, the pressure plate 105 is lowered so that the lower anti-slip plate 104 contacts the concrete block, thereby initially enhancing the installation and fixing of concrete blocks of different sizes. Then, the anti-slip nut 107 is tightened and lowered, which, together with the screw rod 102 and the pressure plate 105, can squeeze and fix the concrete block. At the same time, the servo motor 207 is started to drive the transmission shaft 205 to rotate, which in turn drives the eccentric shaft 206 to rotate, thereby causing the transmission plate 208, the hinge block 209 and the upper receiving plate 101 to vibrate. When the receiving plate 101 reciprocates, the presence of the vibration spring 203 can improve the vibration test effect of the concrete, thus enhancing the practicality of the vibration table.
