Description

Technical Field

[0001] The utility model relates to the technical field of steel bar rust removal, in particular to a rust removal device for pre-buried exposed steel bars. Background Art

[0002] In order to facilitate subsequent construction during the construction process, some pre-embedded exposed steel bars need to be pre-buried. These pre-embedded exposed steel bars will inevitably rust, and the rusted steel bars are not easy to fit tightly with the concrete to form a whole after the concrete is poured. Therefore, the exposed steel bars need to be derusted.

[0003] There are manual rust removal, spray rust removal and grinding rust removal for steel bars. Manual rust removal is to manually use tools such as scrapers, steel wool, gauze, etc. to process rusty steel bars. It has high labor intensity, poor rust removal quality, low efficiency, and poor rust removal effect. Spray rust removal requires special spray equipment, which is not equipped in some small construction sites. Grinding rust removal usually uses electric tools in conjunction with grinding dies for rust removal. Most of the grinding rust removal devices in the prior art are only suitable for ordinary steel bar rust removal, but are not suitable for embedded steel bars. CN202320823625.2 discloses a steel bar rust remover, which can adjust the distance between the two connecting ends connected to the front end of the handle by controlling the operating end at the rear end of the handle, and then control the opening and closing of the brush body so that it can be matched with the sleeve on the steel bar to remove rust. Although this steel bar rust remover increases work efficiency compared to manual rust removal, it still requires manual operation by the staff, and requires very high operational proficiency of the staff, which can easily lead to unclean rust removal and need to be reworked.

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] like Figure 1-Figure 3The rust removal device for embedded exposed steel bars shown in the figure comprises a bracket, the bracket comprises a bottom ring 1 and a top ring 7, the bottom ring 1 and the top ring 7 are fixedly connected through a column 2, and the assembly plate 3 reciprocates along the column 2. A lifting device is arranged between the bottom ring 1 and the top ring 7, and the lifting device is used to drive the assembly plate 3 to slide; the lifting device comprises a screw rod 9, a lifting motor 8, and a nut, the lifting motor 8 is mounted on the top ring 7 and is used to drive the screw rod 9 to rotate, the nut is mounted on the assembly plate 3, and the screw rod 9 is threadedly connected inside the nut.

[0024] The assembly plate 3 is provided with a center hole, in which the rust remover 4 is rotatably connected.
