Description

Technical Field

[0001] The utility model relates to the technical field of concrete test pieces, in particular to a concrete test piece vibration device. Background Art

[0002] A concrete specimen vibration device is a device specially used in the preparation process of concrete specimens to remove bubbles inside concrete and improve the density and uniformity of concrete by vibration. The existing concrete specimen vibration device is not easy to adjust the limit range during use, which makes it impossible to apply to test molds of different specifications.

[0003] A Chinese patent discloses a concrete specimen vibration device (authorization announcement number CN215702546U). The patent technology rotates a hand wheel, which drives a bidirectional screw to rotate, and the bidirectional screw drives two second limit plates to move horizontally, and then moves the first limit plate horizontally, so that the limit range can be adjusted to suit test molds of different specifications.

[0004] However, it has certain drawbacks: the test mold is fixed by rotating the bidirectional screw, but in actual use, vibration will be transmitted to the bidirectional screw, causing it to rotate unnecessary, thereby causing the two second limit plates to loosen the fixation of the test mold, thereby affecting the preparation of concrete specimens. Utility Model Content

[0005] The utility model aims to provide a concrete specimen vibration device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0022] After the vibration motor 3 is started, it drives the vibration base 2 to vibrate, thereby driving the support base 4 to vibrate, and then driving the concrete test mold 21 above the support plate 7 to vibrate;

[0023] Concrete is placed inside the concrete test mold 21, and vibration is used to drive the concrete to be compacted and exhaust the air inside;

[0024] The first spring 6 is used to realize elastic support for the upper structure, so that the upper structure generates elastic vibration and reduces the dynamic load transmitted to the foundation or the structural frame, which helps to reduce the impact of vibration on the surrounding environment and equipment;

[0025] When the adjusting rod 9 is rotated counterclockwise, the two adjusting blocks 10 will move toward the middle at the same time, and when the adjusting rod 9 is rotated clockwise, the two adjusting blocks 10 will move to both sides respectively;

[0026] A rocker is installed at the front end of the adjusting rod 9 to facilitate the rotation of the adjusting rod 9.

[0027] The concrete test mold 21 is installed between the two clamping plates 11 ; a rubber pad is installed on one side of the clamping plate 11 close to the center of the support plate 7 to protect the surface of the concrete test mold 21 .

[0028] exist Figure 1 , Figure 3 and Figure 4 Middle: A mounting plate 12 is mounted on the front surface of the adjustment seat 8, a ratchet 13 is mounted on the front side of the mounting plate 12, the ratchet 13 is mounted on the outside of the adjustment rod 9, a positioning mechanism 14 is arranged on the front surface of the mounting plate 12 and located on the right side of the ratchet 13, the positioning mechanism 14 comprises a mounting column 15, a ratchet 16 is rotatably connected to the outside of the mounting column 15, a mounting block 17 is mounted above the ratchet 16, the rear ends of the mounting column 15 and the mounting block 17 are both mounted on the front surface of the mounting plate 12, a second spring 18 is mounted on the lower surface of the mounting block 17, the lower end of the second spring 18 is fitted to the ratchet 16, the interior of the mounting block 17 is located on the inner side of the second spring 18 and is movably connected with a pull rope 19, the lower end of the pull rope 19 is connected to the ratchet 16, a pull block 20 is mounted on the upper end of the pull rope 19, and the pull block 20 is located on the upper side of the mounting block 17;

[0029] When the adjusting rod 9 is rotated counterclockwise, the pawl 16 will not get stuck on the ratchet 13, and the adjusting rod 9 can rotate normally; when the adjusting rod 9 is rotated clockwise, the pawl 16 will get stuck on the ratchet 13, causing the adjusting rod 9 to be unable to rotate, which prevents the vibration from being transmitted to the adjusting rod 9 and causing it to rotate clockwise unnecessarily, thereby preventing the clamping plate 11 from being loosened;

[0030] Pulling the pull rope 19 drives the pawl 16 away from the ratchet wheel 13, and the adjusting rod 9 can be rotated clockwise;

[0031] The pull block 20 facilitates pulling the pull cord 19 .

[0032] The working principle of the utility model is: when in use, the concrete test mold 21 filled with concrete is placed between the two clamping plates 11 and the adjusting rod 9 is rotated counterclockwise, and the two adjusting blocks 10 will drive the two clamping plates 11 to move toward the middle at the same time, thereby fixing the concrete test mold 21; then the vibration motor 3 in the vibration mechanism 1 is turned on to drive the support plate 7 to vibrate, thereby driving the concrete test mold 21 to vibrate, and the vibration motor 3 is turned off after the vibration is completed; the pull block 20 is pulled upward to pull the ratchet 16 through the pull rope 19, and the adjusting rod 9 is rotated clockwise to drive the two clamping plates 11 to separate, so that the concrete test mold 21 can be taken out.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
