Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically a polishing machine for rust removal of steel structures. Background Technology

[0002] A polishing machine for steel structure rust removal is a specialized piece of machinery used to remove rust, oxide layers, and other contaminants from the surface of steel structures. This equipment is typically driven by electricity or pneumatics, using high-speed rotating brushes or grinding wheels to polish the steel surface, thus cleaning and preparing it. Steel exposed to air, especially in humid environments or those containing chemicals, is prone to oxidation, forming rust. If not removed promptly, rust will gradually spread, weakening the structure's strength and stability. Before applying anti-corrosion coatings or other surface treatments, it is essential to ensure the steel structure surface is clean, free of grease, rust, and other contaminants. A clean, smooth surface significantly improves coating adhesion and durability, thereby extending the service life of the steel structure.

[0003] Existing steel structure rust removal polishing machines are not very flexible in use and are difficult to adapt to different working environments and requirements. Traditional rust removal and polishing mostly rely on manual operation with handheld angle grinders. Long-term operation can easily lead to operator fatigue, especially when dealing with large areas or heavily rusted steel structures, resulting in high labor intensity and low work efficiency.

The two ends of the mounting rod are doubly fixed by nut sleeves and limiting rings to ensure that the angle grinder will not shift or loosen during fixed grinding. The limiting bolts are used to lock the connection between the bent rod and the bracket to prevent angle deviation during grinding and improve grinding consistency. The design of the protective cover effectively prevents the flying of debris generated during grinding and ensures the safety of operators. At the same time, the stable connection between the base and the fixed plate provides a solid support foundation for the entire device, ensuring that the equipment is not easily shaken during high-intensity grinding operations. The overall structural design not only improves grinding efficiency but also significantly improves the flatness and quality of the ground surface. It is suitable for various steel structure rust removal and polishing scenarios and has good practicality and promotion value. Attached Figure Description

[0030] Furthermore, a fixing plate 105 is fixedly connected to the bottom of the support base 106, and the fixing plate 105 is fixedly installed on the top of the base 3.

[0031] Furthermore, a rotating rod 110 is installed at one end of the rotating frame 101, and the front and rear ends of the rotating rod 110 are rotatably connected to the support base 106.

[0032] Furthermore, a fixing frame 107 is fixedly connected to one side of the support base 106, and an arc-shaped strip 109 is provided on the fixing frame 107.

[0033] Furthermore, the arc-shaped strip 109 has several fixing holes 108, and adjusting bolts 104 are installed inside the fixing holes 108. The adjusting bolts 104 are threadedly connected to the bracket 103.

[0034] Furthermore, the grinding mechanism 2 includes an angle grinder 201. The output end of the angle grinder 201 is equipped with a grinding wheel 206 and a fixing nut 212. The bottom of the angle grinder 201 is fixedly connected to a mounting sleeve 209. A mounting rod 204 is installed inside the mounting sleeve 209. One end of the mounting rod 204 passes through the mounting hole 102 on the rotating frame 101 and is threaded with a nut sleeve 211. The other end of the mounting rod 204 passes through the mounting hole 102 on the bracket 103 and is fitted with a limiting ring 208. A bent rod 210 is fixedly connected to one side of the angle grinder 201.

[0035] Furthermore, the fixing nut 212 is threaded onto the output end of the angle grinder 201 to tighten the grinding wheel 206.

[0036] Furthermore, a protective cover 205 is fixedly connected to the other side of the angle grinder 201, and the protective cover 205 is located outside the grinding wheel 206.

[0037] Furthermore, a handle 207 is fixedly connected to the other end of the mounting rod 204, the surface of the bent rod 210 is movably connected to the inner wall of the bracket 103, and a limit bolt 213 is installed on the bent rod 210, which is threadedly connected to the bracket 103.

[0038] Furthermore, a handle 203 is installed on the top of the angle grinder 201, and a control button 202 is installed on the inside of the handle 203.

[0039] Place the base 3 on a stable working surface, and connect the fixing plate 105 to the base 3 through the support base 106 to ensure overall stability.

[0040] The rotating frame 101 is rotatably connected to the support base 106 via the rotating rod 110, allowing for angle adjustment.

[0041] When large-area and long-term grinding is required, the grinding mechanism 2 and the support mechanism 1 are assembled. During installation, the angle grinder 201 is first placed on the opposite side of the rotating frame 101 and the bracket 103. The mounting rod 204 is passed through the mounting sleeve 209. The two ends of the mounting rod 204 pass through the mounting holes 102 of the rotating frame 101 and the bracket 103, respectively.

[0042] When the grinding angle of the grinding mechanism 2 needs to be adjusted, the operator holds the handle 207 and then raises or lowers the mounting rod 204, mounting sleeve 209 and angle grinder 201, thereby moving the rotating frame 101 up and down. The rotating frame 101 drives the rotating rod 110 to rotate inside the rotating frame 101, and simultaneously drives the bracket 103 and the grinding mechanism 2 to rotate up and down. After the adjustment is completed, the adjusting bolt 104 is screwed into the bracket 103 through the fixing hole 108 on the arc strip 109 to fix the bracket 103 and the rotating frame 101. The fixing bracket 107 fixes the arc strip 109.

[0043] After adjustment, the steel structure is ground and polished. The steel structure workpiece to be processed is placed on the base 3, ensuring that its surface is unobstructed in contact with the grinding wheel 206. The operator starts the angle grinder 201 through the control button 202 on the handle 203. The motor inside the grinding wheel 206 starts working, and the output shaft of the motor drives the grinding wheel 206 to start rotating at high speed. The operator pushes the steel structure into contact with the grinding wheel 206, and the surface of the grinding wheel 206 and the steel structure come into contact for polishing. The protective cover 205 covers the grinding wheel 206 to prevent debris from flying during the grinding process and to maintain the best contact angle between the grinding wheel 206 and the workpiece surface.

[0044] When hand-held grinding is required, loosen the limit bolt 213, take out the mounting rod 204, and hold the angle grinder 201 with the handle 203 to provide convenient operation. Manually move the angle grinder 201 to perform local treatment on the details of the steel structure workpiece. Depending on the shape of the workpiece and the degree of corrosion, flexibly switch between fixed grinding and hand-held grinding modes to improve the flexibility of use.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
