Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a vibrating device for forming concrete test blocks. BACKGROUND

[0002] The concrete test block is a cube or a test piece of a specific shape made according to the standard method, which is used to test the mechanical properties and durability of concrete. The test block forming requires a special vibrating device. The vibrating device applies vibration energy to the mixed material in the concrete test mold through mechanical vibration, reduces the adhesion and internal friction of the mixed material, makes the aggregate arrange densely under the action of gravity, discharges gas and eliminates voids, and finally realizes the dense filling of the cement paste and the aggregate, so as to ensure that the test block forming quality meets the construction standard requirements. Therefore, the patent with the publication number CN214871368U discloses a concrete test block vibrating device for building, which comprises a vibrating box body, a gear ring and a driving assembly. The front surface and the back surface of the vibrating box body are respectively connected with the front surface and the back surface of the inner wall of the connecting frame. The driving assembly, the disc, the lead screw, the connecting nut, the vibrating assembly, the gear and the gear ring are arranged. The meshing action between the gear and the gear ring controls the rotation of the connecting shaft and the cam. At the same time, the cam extrudes the contact plate downward to move. At the same time, the thread action between the lead screw and the connecting nut ensures that the lead screw rotates while moving downward, so that the vibrating assembly can rotate and move up and down. When the cam extrudes the contact plate upward, the lead screw rotates upward at the same time, and the disc drives the vibrating assembly to rotate around the driving assembly. The device can rotate and move up and down while vibrating the concrete, so as to ensure good efficiency and effect of vibrating the concrete. The concrete test block vibrating device in the above-mentioned can rotate and move up and down by the vibrating assembly itself, so as to ensure good efficiency and effect of vibrating the concrete. However, the energy distribution of the rotating vibrating head is uneven. The vibration force is strong in the area close to the rotation center and weak in the area far from the rotation center, forming a ring-shaped density distribution with the rotation axis as the center. The test block will leave spiral vibration texture inside, the density is uneven, and the rotating vibrating head will produce strong shearing and stirring to the aggregate which has been uniformly distributed. This excessive mechanical action is easy to cause segregation, which affects the final strength and homogeneity of the concrete. SUMMARY

It also integrates multiple automated processes such as lifting, rotating, unfolding and repositioning, realizing the full automation of the process from internal insertion vibration to surface vibration. 1. By incorporating an unfolding structure, the internal unfolding structure allows vibration energy to radiate evenly from the center to the surrounding area, effectively eliminating the weak zone at the junction of the cones that exists in single-point vibration. The vibrator built into the edge limiting structure acts directly on the side wall of the mold, precisely liquefying the edge concrete and completely solving the industry problem of insufficient density at the edge of the test block caused by the boundary effect.

The entire process from internal insertion vibration to surface vibration is automated, effectively reducing manual intervention and greatly improving production efficiency. Furthermore, a precision locking and unlocking mechanism composed of sliders, slide rails, and locking blocks is adopted to accurately convert the rotational motion of the lead screw into the required complex actions such as linear descent, rotational positioning, and linear ascent. The structure is compact and the motion trajectory is precise. 2.
