Problems solved by technology

[0003] When the bare end of the pre-embedded steel bar needs to be derusted, it is necessary to manually polish the steel bar with hand-held sandpaper. However, the grinding efficiency of this method is low, and it requires more manpower and sandpaper. The arrangement is uneven, and the existing grinding equipment is not convenient for grinding them at the same time, so multiple grindings are required, and it is difficult to completely polish the rust on the steel bars through the existing grinding equipment, which will cause the steel bars at the exposed ends to be exposed in a humid environment. It will rust again, which will affect the welding of steel bars

Abstract

The invention relates to the technical field of grinding equipment, in particular to a derusting and polishing device for an exposed end of an embedded steel bar in constructional engineering and a using method thereof. The device comprises a lifting mechanism, a grinding mechanism is fixedly arranged at one side of a lifting plate, and a paint spraying mechanism is fixedly arranged at the top of the lifting plate. According to the device, the output end of a second driving motor can drive a rotating rod to rotate, so that a fixing column on the rotating rod can drive a worm to rotate, the worm can drive a first gear to rotate, and therefore a second gear can be driven to rotate through the first gear; in this way, the second gear can drive a rotating sleeve to rotate, sliding blocks at the two sides of the rotating sleeve can enable two arc-shaped grinding plates to extrude and attach steel bars under the action of extension springs, and the rotating sleeve can drive the two arc-shaped grinding plates to rotate; and therefore, grinding blocks on the arc-shaped grinding plates can grind the outer walls of the steel bars, and the grinding efficiency of the steel bars can be improved.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a derusting and grinding device for the exposed end of pre-embedded steel bars in construction engineering and a use method thereof. Background technique [0002] During the construction process of the construction project, by pouring concrete on the prefabricated steel bars, a certain length of steel bars is generally reserved for re-welding the steel bars later, but the ends of the steel bars reserved outside will be exposed to the air for a long time and be damaged. Moisture rusts in the air. During later construction, it is necessary to polish off the rust on the outside of the reserved steel bars, so as to ensure that the steel bars can be effectively welded together with the welded steel bars during welding. [0003] When the bare end of the pre-embedded steel bar needs to be derusted, it is necessary to manually polish the steel bar with hand-held sandpaper. How...
