Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a concrete defoaming device for building construction. Background Art

[0002] During the concrete mixing and pouring process, some air is easily mixed in. The bubbles in the concrete mixture can neither escape by themselves nor be expelled by their own weight, so vibration is an important means to make the concrete dense and remove bubbles. If defoaming work is not carried out in time, various pores will appear inside and on the surface of the concrete after solidification, affecting the quality of the concrete. During vibration, the aggregate particles are close to each other, and the air is squeezed to the upper part with part of the cement slurry, and the bubbles emerge with the help of vibration force. Existing plug-in concrete vibrators are generally placed directly at the required position through the base frame, and because the body of the vibrator is relatively heavy, when it needs to be rotated at an angle during use, the staff needs to spend more effort to rotate the entire device, which reduces the user experience of the entire device to a certain extent.

[0003] Therefore, a rapid defoaming device for precast concrete parts is proposed in Chinese Patent Publication No. CN217318438U. By rotating the end of the vibrator, the device will drive the vibrator body located on the support plate to rotate. At this time, the rotating support plate will drive the rotating ring to rotate on the outer wall of the connecting ring through the connecting piece on the bottom side, so as to complete the rotation of the entire vibrator body, and achieve 360° angle adjustment of the vibrator, thereby eliminating the need to manually hold the vibrator to rotate to control the angle, saving physical effort and improving the sense of use.

[0004] However, when the vibrator is working, it is not easy to fix the position of the vibrating end of this device, which requires manual holding during operation. The workers' arms will feel uncomfortable in cold weather or after holding the vibrator for a long time. In view of this, we propose a concrete defoaming device for construction. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The present invention starts the forward and reverse motors to drive the rotating shaft to drive the clamp ring to rotate. Under the action of the cross groove, the damping plate drives the shock absorbing mechanism to rotate as the clamp ring rotates, so that the vibrator and the support plate can be rotated, and the vibrating end of the vibrator can be adjusted 360 degrees.
