Description

Technical Field

[0002] Construction engineering equipment refers to equipment that assists workers in construction in the field of construction engineering. During the construction process, it is sometimes necessary to pre-bury steel bars in the soil. At this time, the exposed steel bars are easily oxidized and rusted. When pouring concrete on the rusted steel bars, the rust attached to the surface of the steel bars will affect the concrete's wrapping of the steel bars, thereby greatly reducing the strength of the reinforced concrete.

[0003] Existing rust removal devices, such as a rust removal device for pre-buried exposed steel bars in construction projects disclosed in the utility model patent application number 202120576214.9, have a main structure including a shell, the inner top and inner bottom of the shell are rotatably mounted with horizontally arranged threaded rods, one end of the two threaded rods extends to the outside of the shell and is fixedly mounted with sprockets respectively, the two sprockets are connected to the same chain for transmission, a second motor is fixedly mounted on the outer bottom of the shell, the outer side of the movable plate is fixed to one end of the two connecting rods, the other end of the two connecting rods is fixedly mounted with the same fixed plate, and the outer side of the fixed plate A steel brush is installed on the side sliding; when in use, the second motor is driven by the two threaded rods to make the two sprockets rotate synchronously, so that the movable plate moves horizontally to the right, so that the steel brush moves in the same way. When the steel brush moves to contact the exposed steel bar, the second motor stops working, and then the first motor is driven to rotate the vertical rod, thereby driving the two bevel gears to rotate synchronously, so that the rotating shaft rotates. The rotation of the rotating shaft causes the two cams to rotate synchronously. The rotation of the cam causes the horizontal plate to reciprocate in the vertical direction, thereby driving the steel brush to obtain the same vertical reciprocating motion.

[0004] However, most existing rust removal devices have a weak connection with steel bars. During the rust removal process, the steel bars are prone to shaking, affecting the stability of the steel bars.
