Problems solved by technology

[0003] During the subway construction process, since the steel bars are placed on the construction site, they are easy to rust. Before the steel bars are used, they need to be derusted. The existing rust removal equipment is derusted one by one by the staff, and the work efficiency is low. At the same time, the labor intensity of the staff is increased

Embodiment 1

[0022] see Figure 1~2 , in an embodiment of the present invention, an automatic steel bar derusting equipment for engineering construction, comprising a frame 1 and a grinding and derusting assembly, the bottom of the frame 1 is evenly and symmetrically fixed with supporting legs 21, and the bottom ends of the supporting legs 21 are equipped with rollers 22. The roller 22 is a self-locking roller, which facilitates the movement of the device. The grinding and derusting assembly is installed on the frame 1. An automatic feeding assembly and an automatic discharging assembly are respectively installed on both sides of the grinding and derusting assembly. The automatic feeding assembly includes a material box 13, a stage 14 and a mechanism for pushing steel bars to the input end of the grinding and derusting assembly. The top of the material box 13 is installed on the top of the frame 1 through the first electric push rod. In this implementation In an example, the two ends of th...

Embodiment 2

[0026] see image 3 The difference between the embodiment of the present invention and the embodiment 1 is that, in order to facilitate the discharge of the grinding rust, the grinding sleeve 6 is provided with a plurality of drains 23 for the discharge of the rust.

[0027]The working principle of the present invention is: when the present invention is in use, a steel bar at the bottom of the material box 13 falls on the object stage 14, and the second motor 20 drives the screw mandrel 15 to rotate, and the screw mandrel 15 drives the connecting block 18 to move, and connects Block 18 drives push plate 16 to move, and steel bar is pushed to grinding and derusting assembly, and steel bar enters in the grinding sleeve 6, and power mechanism drives grinding sleeve 6 to rotate, and grinding sleeve 6 drives grinding sheet 7 to rotate, and steel bar surface is polished, By rotating and adjusting the bevel gear 8, the bevel gear 8 drives the driving bevel tooth disc 10 to rotate, an...

Abstract

The invention discloses an automatic steel bar derusting equipment for engineering construction, which comprises a frame and a grinding and derusting component. An automatic feeding component and an automatic discharging component are respectively installed on both sides of the grinding and derusting component. The automatic feeding component includes The material box, the stage and the pushing mechanism for pushing the steel bar to the input end of the grinding and derusting assembly, the grinding and derusting assembly includes a grinding sleeve, a power mechanism for driving the grinding sleeve to rotate, and a A grinding sheet and an adjustment mechanism for adjusting the position of the grinding sheet, the adjustment mechanism includes a driving bevel gear, an adjustment bevel gear, a first movable block and a second movable block, the application is provided with an automatic feeding assembly and an automatic discharging assembly, Through cooperation, the steel bar can be continuously polished and derusted, with a high degree of automation, which improves the work efficiency and reduces the labor intensity of the workers; it is equipped with an adjustment mechanism to facilitate the adjustment of the grinding amount, and can adapt to steel bars of different diameters.

Description

technical field [0001] The invention relates to a rust removal device, in particular to an automatic steel bar rust removal device for engineering construction. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. Steel bars for reinforced concrete refer to the straight or coiled steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar. The delivery state is straight bar and coiled round. [0003] During the construction of the subway, because the steel bars are placed on the construction site, they are easy to rust. Before the steel bars are used, they need to be derusted. The existing derusting equipment is derusted one by one by the staff, and the work efficiency is low. Increased staff labor inten...
