FIG. 2 is a schematic view showing the up-and-down rotation of the polishing device for overhead work according to the present invention.
In the figure: 1 upper handle, 2 wire clamps, 3 sand paper bonding plates, 4 lower support plates, 5 direct current motors, 6 lower handles, 7 lithium battery packs, 8 switches, 9 limit screws, 10 height adjusting nuts, 11 guide sleeves, 12 positioning nails, 13 guide posts, 14 limit springs, 15 locking screws, 16 positioning springs, 17 opening sleeves and 18 upper support plates.
Detailed Description
As shown in fig. 1 to 2, the polishing device for high-altitude operation of the invention comprises six parts, namely an upper supporting component, a connecting component, a lower supporting component, an elastic positioning mechanism, an electric system (a direct current motor) and a polishing component (a sand paper sticking disc).
The upper supporting component comprises an upper supporting plate 18, an upper lifting handle 1 (convenient for handheld operation) is fixed on the upper surface of the upper supporting plate, a ball bearing and a bullseye bearing can be arranged on the lower surface of the upper supporting plate, and the upper supporting plate can also be directly coated with a lubricating coating, including molybdenum disulfide, a diamond-like film, teflon and the like. The upper supporting plate is connected with one end of the lower supporting plate through a guide post of the connecting component. The space height between the upper supporting plate and the lower supporting plate can be adjusted by compressing the limiting spring through the height adjusting nut, and meanwhile, the space height adjusting nut can be used for adjusting the compression degree. The abrasive paper polishing machine is mainly used for being close to the back surface of a part of the wire clamp 2 to be polished, and the abrasive paper sticking disc is driven to move freely on the wire clamp, so that the polishing operation of the surface of the whole wire clamp part is completed.
The lower support assembly comprises a lower support plate 4, a direct current motor 5 is arranged at the other end of the lower support plate, a motor shaft of the direct current motor penetrates through the lower support plate to be connected with a detachable sand paper sticking disc 3, and sand paper can be replaced according to requirements; the sand paper sticking plate is opposite to the lower surface of the upper supporting plate, and a lower handle 6 is fixedly arranged on the base of the direct current motor. The lower support plate is also provided with a lithium battery pack and a switch 9. The lithium battery pack 7 is a rechargeable battery, and can be directly connected with a charger plug for charging without being detached. The battery should be charged in advance before working, and the backup battery is recommended to be charged according to actual needs.
The connecting component comprises a guide post 13 for connecting the upper supporting plate and the lower supporting plate, the upper end of the guide post is fixed on the lower surface of the upper supporting plate through a locking screw 15, and the lower part of the guide post penetrates through the lower supporting plate to be connected with a height adjusting nut 10 and a limit screw 9; the periphery of the upper part of the guide post is provided with a limit spring 14, the outside of the limit spring is provided with a height limit ring arranged on the upper supporting plate, the height limit ring can ensure the minimum clearance, and the periphery of the lower part of the guide post is provided with a guide sleeve 11.
The elastic positioning mechanism consists of a positioning nail 12 and an opening sleeve 17, the lower part of the positioning nail is arranged at the lower end of a limiting spring through the opening sleeve arranged at the lower end of the height limiting ring, and the periphery of the upper part of the positioning nail is provided with a positioning spring 16. The upper and lower support plates are connected and placed for rotation through the opening sleeve and the positioning spring by the positioning nail, and the upper and lower support plates can freely rotate within a 360-degree range after the positioning nail is pulled out (as shown in figure 2).
The using method comprises the following steps:
1. taking out the polisher and charging, and working after charging is completed. Charging dissatisfaction may result in a reduction in sanding time. The backup battery can be fully charged as necessary for replenishment.
2. When polishing the lower plane of the wire clamp, the upper and lower assemblies are integrally used, the lower plane of the upper support plate is contacted with the upper plane of the wire clamp, then the height adjusting nut is slightly loosened, whether the gap between the lower plane of the upper support plate and the sand paper sticking disc is enough or not is checked, and when the gap is insufficient, the height adjusting nut is continuously loosened. If the gap is too large, the height adjusting nut is screwed down, the polishing effect is affected by the gap, and even the gap is too small, so that the height adjusting nut may not work. Because the thickness of the parts of the device clamp is different, the device clamp needs to be summarized in actual work. After the gap between the wire clamp and the polisher is adjusted, after the inspection locating nail is inserted, the motor switch is pressed down, the sand paper sticking disc rotates, and the handle is held by hands to move on the upper plane of the wire clamp so as to polish the lower plane of the wire clamp.
3. If the upper plane of the wire clamp is polished, the step 2 is referred to, and the lower plane of the upper support plate is contacted with the lower plane of the wire clamp. Or the elastic positioning mechanism is pressed down to separate the upper supporting component from the lower supporting component, and the lower supporting component and the motor thereof are independently used for polishing.
