Description

Technical Field

[0001] The utility model relates to the field of engineering equipment, in particular to a vibration device for permeable concrete. Background Art

[0002] Permeable concrete refers to concrete with a porosity of 15% to 25%. Commonly used permeable concrete mostly uses cement, asphalt or polymer resin as the binder. During the paving process of permeable concrete, it needs to be vibrated and compacted, and its porosity needs to be controlled. At present, most of them use flat vibrators to vibrate the surface to make it dense, and control the porosity by manually controlling the vibration time. Due to the inconsistency of control by different operators, it is easy to make the permeable concrete vibrated too dense or too loose, which will affect the performance; in addition, during the vibration process, due to the viscosity of the binder of the permeable concrete, it is easy to adhere to the bottom wall of the vibrator and needs to be cleaned manually. For concrete with cement as the binder and bonded to the bottom wall of the vibrator, if it is not completely dry, it can be cleaned by scraping and washing with water in time; but for concrete prepared with asphalt or polymer resin as the binder after hot melting and bonded to the bottom wall of the vibrator, it is very inconvenient to clean after cooling. At present, there are public technologies that mention setting a heating layer in the bottom plate of a permeable concrete vibrating compactor to reduce adhesion. For example, the utility model patent with the authorization announcement number CN210341564U discloses "A Handheld Permeable Concrete Vibrating Compactor", which describes: "... the heating layer is located in the bottom plate, and resistance wires are evenly distributed in the heating layer... The heating layer is set up, and when the concrete is compacted, it can effectively prevent the concrete from adhering to the bottom plate and affecting the use..." This technology embeds the heating layer in the bottom plate and heats the bottom plate when the concrete is vibrated and compacted, which can reduce the adhesion of permeable concrete prepared with hot melt asphalt or polymer resin as the binder material. However, permeable concrete made of cement as a binder is more widely used. Adhesives formed during the vibration of cement-bonded permeable concrete can be cleaned by scraping or flushing without heating. Therefore, if a base plate with a heating layer is used for the vibration of such permeable concrete that does not require heating, it is not necessary and the resistance wire is always in a vibrating state, which is easy to be damaged. In addition, the heating layer made of resistance wire is a consumable part. If it is embedded in the vibrating base plate, it is not easy to replace when damaged. Sometimes it needs to be replaced together with the base plate, which is neither economical nor convenient. In view of this, it is necessary to improve the vibration device for permeable concrete.

The utility model improves the vibration device for permeable concrete, and the heating plate and / or a plurality of counterweights are detachably placed on the bottom plate of the vibration disk assembly.

[0023] The present invention is further described below through specific implementation methods.

[0024] like Figures 1 to 7 As shown, a vibration device for permeable concrete described in the utility model includes a vibration motor 1, a vibration plate assembly 2, a counterweight 3 and a heating plate 4. The vibration motor 1 is locked on the top of the vibration plate assembly 2; the vibration plate assembly 2 includes a bottom plate 21, a pillar 22, a pressure plate 23, a screw 24, a top plate 25 and a handle 26. The top plate 25 is a square flat plate, and the pillar 22 is a rigid pillar. The pillar 22 is four pieces, and the four pillars 22 are fixed between the bottom plate 21 and the top plate 25.
