DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] See also Figure 1-3 A vibrating table for concrete includes a base 1 with a supporting function, and a vibrating table 2 is fixedly connected to the base 1 through an elastic connection structure. The elastic connection structure is used for connection, so that the vibrating table 2 can compress the length of the elastic connection structure after being subjected to force, driving the vibrating table 2 to vibrate up and down repeatedly, thereby compacting the concrete.

[0031] A vibration device for driving the vibration table 2 to vibrate is fixedly installed on the upper surface of the base 1 below the vibration table 2. The vibration table 2 is driven to vibrate up and down by the vibration device.

[0032] A cavity 5 is provided on the top of the vibration table 2, and a slide bar 6 is fixedly connected to the inner walls at both ends of the cavity 5. Two symmetrically arranged movable plates 7 are sleeved on the outer surface of the slide bar 6, and the two movable plates 7 are slidably connected to the slide bar 6. The two movable plates 7 are connected by a sliding connection so that the two movable plates 7 can move toward or in opposite directions along the slide bar 6.

[0033] The second spring 8 is fixedly connected to the side away from the middle section of the two movable plates 7, and the end of the second spring 8 away from the movable plate 7 is fixedly connected to the inner wall of the cavity 5. The user can slide the two movable plates 7 in the opposite direction to squeeze the second spring 8 to contract and adjust the distance between the two movable plates 7.

[0034] A slide groove 9 is provided on each adjacent side of the two movable plates 7, and two clamping columns 10 are slidably connected inside each slide groove 9. A specimen mold box 11 is sandwiched between the two movable plates 7, and fixing holes 12 are provided on the side walls of the specimen mold box 11. The free ends of the clamping columns 10 are embedded in the fixing holes 12 and plugged into the specimen mold box 11 through the fixing holes 12. Thus, the specimen mold box 11 is fixed between the two movable plates 7, and the specimen mold box 11 is fixed.

[0035] When in use, the user first slides the two movable plates 7 in the opposite direction along the length direction of the slide rod 6, and the second spring 8 is squeezed and contracted by the movable plates 7 until the gap between the two movable plates 7 is larger than the width of the specimen mold box 11. Then, the user embeds the specimen mold box 11 into the gap between the two movable plates 7, and slides the clamping column 10 along the length direction of the slide groove 9 to move the clamping column 10 to align with the fixing hole 12 opened on the specimen mold box 11. After loosening the movable plates 7, the two movable plates 7 push the clamping column 10 to be inserted into the fixing hole 12 under the elastic force of the second spring 8, and the specimen mold box 11 can be fixed on the vibration table 2. At this time, the vibration equipment can be started to drive the vibration table 2 to vibrate, and the concrete inside the specimen mold box 11 can be vibrated and compacted. The specimen mold box 11 is fixed by the clamping connection mode of the clamping column 10, and the existing vibration compaction device is avoided as much as possible to screw the specimen mold box 11 on the vibration table 2 through the mounting column. When fixing the specimen mold box 11, it is necessary to connect it multiple times, which leads to the problem of inconvenience in using the existing concrete vibration compaction device.

[0036] Reference Figure 1 The elastic connection structure includes a first spring 3 disposed between the base 1 and the four corners of the vibration table 2, and both ends of the first spring 3 are fixedly connected with a connecting piece 4, one end of the first spring 3 is rotatably connected to the base 1 through the connecting piece 4, and the other end of the first spring 3 is fixedly connected to the vibration table 2 through the connecting piece 4. The connecting piece 4 is provided to increase the contact surface between the two ends of the first spring 3 and the vibration table 2 and the base 1, thereby improving the stability of the connection of the first spring 3.

[0037] Reference Figure 1, both ends of the movable plate 7 are provided with round holes, and the two ends of the movable plate 7 are sleeved on the slide rod 6 through the round holes and are slidably connected with the slide rod 6. The movable plate 7 is slidably connected with the slide rod 6 through the round holes, so that the spacing between the two movable plates 7 can be adjusted to adapt to the test piece mold box 11 of different widths.

[0038] Reference Figure 1 When the second spring 8 is in an extended state, the adjacent ends of the two movable plates 7 are in contact with each other. When the second spring 8 is not compressed, the two movable plates 7 are in contact with each other, which can greatly increase the clamping force of the second spring 8 on the specimen mold box 11 with a relatively low width, thereby improving the fixing effect on the specimen mold box 11.

[0039] Reference Figure 3 The clamping column 10 is a cylindrical structure, and the length of the clamping column 10 is greater than the inner cavity depth of the chute 9. The clamping column 10 is extended outward from the inner cavity of the chute 9, so that the user can conveniently insert the end of the clamping column 10 located outside the inner cavity of the chute 9 into the fixing holes 12 opened on both sides of the specimen mold box 11 to fix the specimen mold box 11.

[0040] Reference Figure 1 and Figure 2 The vertical distance between the fixing hole 12 and the bottom of the specimen mold box 11 is equal to the distance between the clamping column 10 and the bottom wall of the cavity 5. When the bottom wall of the specimen mold box 11 is fitted with the inner wall of the cavity 5, the height of the fixing hole 12 is flush with the height of the clamping column 10, which facilitates the insertion of the clamping column 10 into the fixing hole 12.

[0041] Reference Figure 1 and Figure 3 The vibration device includes a motor 13, a turntable 15 is fixedly connected to the output end of the motor 13, a transmission plate 16 is eccentrically arranged on the side of the turntable 15 away from the motor 13, and connection holes 17 are provided at both ends of the transmission plate 16. One end of the transmission plate 16 is rotatably connected to the turntable 15 through the connection hole 17, and the other end of the transmission plate 16 is rotatably connected to the bottom wall of the vibration table 2. An L-shaped connecting rod is provided at the bottom of the vibration table 2, and the vertical section of the connecting rod is fixedly connected to the bottom of the vibration table 2. A connecting shaft is eccentrically arranged on the turntable 15, and the two ends of the transmission plate 16 are respectively sleeved on the connecting shaft and the horizontal section of the connecting rod through the connection hole 17. When the motor 13 rotates, it can drive the vibration table 2 to move up and down through the transmission plate 16 to compact the concrete inside the specimen mold box 11.

[0042] Reference Figure 3 The bottom of the motor 13 is fixedly connected with a mounting seat 14, and a bolt is passed through the mounting seat 14, and the bolt is screwed to the base 1 after passing through the mounting seat 14. The mounting seat 14 is provided to improve the stability of the installation of the motor 13, and the bolt screw connection mode is adopted, which is not only stable, but also convenient for users to install and disassemble.

[0043] The implementation principle of the present application is as follows: when in use, the user first slides the two movable plates 7 in the opposite direction along the length direction of the slide bar 6, and compresses the second spring 8 through the movable plates 7 to contract until the gap between the two movable plates 7 is larger than the width of the specimen mold box 11. Then, the user embeds the specimen mold box 11 into the gap between the two movable plates 7, and slides the clamping column 10 along the length direction of the slide groove 9, and moves the clamping column 10 to align with the fixing hole 12 opened on the specimen mold box 11. After loosening the movable plates 7, the two movable plates 7 are in the elastic force of the second spring 8. Push the clamping column 10 downward and insert it into the fixing hole 12, so that the specimen mold box 11 can be fixed on the vibration table 2. At this time, the vibration equipment can be started to drive the vibration table 2 to vibrate, and the concrete inside the specimen mold box 11 can be vibrated and compacted. The specimen mold box 11 is fixed by the clamping connection method of the clamping column 10, which avoids the problem that the existing compaction device screws the specimen mold box 11 on the vibration table 2 through the installation column. When fixing the specimen mold box 11, it is necessary to make multiple connections, which makes the existing concrete compaction device inconvenient to use.
