Description

TECHNICAL FIELD

[0001] The utility model relates to a structure, especially to a defoaming roller structure which can greatly improve service life, and belongs to the technical field of defoaming roller for self-leveling construction. BACKGROUND

[0002] In construction, the defoaming roller for self-leveling construction often cannot be used normally due to excessive wear between the end cover of the defoaming roller and the support shaft of the defoaming roller. At this time, the needle can still be used if only a small amount of wear occurs, but the end cover cannot support the center shaft to roll the roller stably, resulting in the defoaming roller being scrapped.

[0003] In self-leveling construction, there are two main factors affecting the service life of the defoaming roller: 1) the needle is worn to the extent that it cannot be used; 2) the support structure of the defoaming roller is damaged by wear during use. Of the two factors, the second point is the dominant factor affecting the service life of the defoaming roller.

[0004] In construction, the continuous friction between the rolling needle and the ground will cause the tip surface to wear. The speed and degree of wear depend on the material properties of the needle and the sliding method of the defoaming roller. Currently, the needle is made of plastic PE, PP, PA, or stainless steel needle, and its wear resistance is not a problem. The end surface wear mainly depends on the sliding method of the defoaming roller operated by workers. 1) If the defoaming roller always rolls straight during construction, the needle will wear very little. 2) If the defoaming roller sweeps in a circular arc during construction, the roller rolls continuously and comes to a stop, then the needle end surface and the ground undergo hard friction, and the needle end surface will be severely worn. In reality, the second point is the main reason for needle wear.

[0005] The destruction of the roller support structure is the main factor affecting the service life of the defoaming roller for self-leveling construction. During construction, the defoaming roller rolls, and the slurry is constantly splashed inside and outside the iron clamp. These slurry flows along the inner wall of the iron clamp to the metal through shaft, and then seeps into the inner wall of the plastic end cover support hole along the metal through shaft. As the construction time increases, the slurry seeping into the inner wall of the plastic end cover support hole continuously hardens to have diamond sand properties. These continuously hardened slurry and the inner wall of the plastic end cover support hole and the metal through shaft are ground at high speed during the rolling of the roller, resulting in wear of the plastic end cover and the metal through shaft. After multiple constructions, the service life of the defoaming roller ends. In reality, when this phenomenon is serious, a defoaming roller is scrapped after less than 2500 square meters of construction.

[0006] There are two ways to improve the service life of the defoaming roller by improving the structure: 1) improving the wear resistance of the inner wall of the end cover support hole and the support shaft; 2) blocking the slurry from seeping into the friction surface of the end cover support hole and the support shaft, so that a diamond sand friction layer cannot be formed on this surface.

[0007] Therefore, it is particularly necessary to provide the defoaming roller structure which has reasonable structure design, can solve the above-mentioned defects, and prolong service life. Content of the utility model

[0008] The utility model discloses a defoaming roller structure which has simple and reasonable structure design, is safe and reliable, increases the blocking ring, prevents cement slurry from pouring into the roller, and greatly prolongs service life.

[0009] The utility model discloses a defoaming roller structure which has simple and reasonable structure design, is safe and reliable, increases the blocking ring, prevents cement slurry from pouring into the roller, and greatly prolongs service life.

[0010] As preferred, the utility model further includes a steel sleeve, and a support hole is formed in each end cover, and the steel sleeve is embedded in the support hole.

[0011] As preferred, the utility model discloses that the iron clamp adopts chrome-plated flat iron frame, and the support shaft adopts galvanized core steel.

[0012] As preferred, the utility model discloses that the iron clamp and the support shaft are fixed through bolts.

[0013] Compared with the prior art, the utility model has the following advantages and effects: 1) the overall structure is reasonable and safe and reliable, and the blocking ring is added between the end cover support hole and the inner side of the iron clamp at both ends of the support shaft, so that the slurry flowing along the inner side wall of the iron clamp is prevented from penetrating into the inner wall of the end cover support hole, steel-steel friction is only generated between the support shaft and the inner wall of the end cover support hole, and steel-diamond hardness layer (formed by the penetrating self-leveling mortar) -steel friction is not formed; 2) the steel sleeve is embedded in the inner wall of the support hole of the end cover, so that steel-steel friction is generated between the support shaft and the inner wall of the end cover support hole, instead of plastic-steel linear contact surface friction, and the service life of the plastic end cover is greatly prolonged.
