The reel 43 is provided with two grooves designed to wind two wire ropes without the two ropes interfering with each other. The same steering of the reel is realized by different winding modes, but the motion states of the steel wire rope are different. The reel 43 is connected to a rigid coupling by the winding rod 11, and is connected to the second stepping motor 9 through the rigid coupling. Although rigid couplings are not suitable for use in high speed activities, the speed of wall sanding is not rapid, and therefore they have the characteristics of light weight, ultra-low inertia, and high sensitivity to meet the connection requirements herein.
Wherein, the pulley is a V-shaped 1.2 inch rail wheel made of 304 stainless steel. The whole weight of the grinding body is not very heavy, and the bearing weight of the 1.2-inch V-shaped 100Kg can completely meet the use requirement. The model with larger size and higher strength does not need to be selected.
The second stepper motor 9 is selected because of the need to control the forward and reverse rotation of the reel back and forth. Although the stepping motor has the disadvantage of being incapable of providing a large torque and a high rotation speed, the stepping motor is a reasonable choice because the high rotation speed is not required for wall grinding and because the weight of the grinding body is not heavy for wall grinding.
The working principle and the working process of the automatic wall grinding device are as follows:
and S1, firstly setting the initial position reading of the moving plate on the main plate to be 0, and then screwing out the adjusting nut 7 on the adjusting bolt 6 connecting the main plate 36 and the moving plate 22 until the scale is the grinding depth.
S2, turning on a control power supply of the trolley, rotating the driving wheel 63 to the position where the plane is at the lowest position, and moving the trolley to the front of the wall to enable the sanding head 1 to be parallel to and tightly attached to the wall. So that the moving plate 22 again reads 0 on the main plate 36.
S3, start the control system and the cleaner 47. At this time, the second stepping motor 9 starts to rotate in a certain direction at a certain rotating speed, the second stepping motor 9 drives the reel 43 to rotate, the reel 43 pulls the steel wire rope 35, the steel wire rope 35 is connected with the main plate 36, and the main plate 36 drives the sanding head 1 to move upwards or downwards along the vertical direction. Sanding begins because the sanding head rubs against the wall under the action of the spring 8. When the polishing head 1 moves upwards or downwards along the vertical direction, the travel switch is triggered, the second stepping motor 9 rotates towards the other direction, the moving direction of the polishing head 1 is changed at the moment, and polishing continues. In this way, the moving plate 22 will move forward and stop at the position of the nut, and the polishing depth is fixed. At this time, the control system is notified by the sensor, and the servo motor 31 on the linear slide table module starts to move.
S4, the servo motor 31 starts to move, the linear guide rail 33, the sliding block 56 and the polishing head 1 integrally start to ascend, and when the height rises and is about to touch the top of the wall, the control system controls the servo motor 31 to stop rotating. The second stepping motor 9 does not need to be stopped during this process, and the normal operation is always maintained. When the moving plate 22 is stopped again at the nut position, the dc gear motor 60 on the cart drives the driving wheel 63 to rotate, thereby driving the cart and the whole device to move along the wall.
S5, the cart will move forward a distance of the length of the diameter of the sanding head 1. Then, the polishing is continued, and when the moving plate 22 stops at the nut position again, the control system controls the servo motor 31 to move reversely, so that the overall height of the polishing head 1 is reduced to the minimum value again, and the polishing head 1 travels on the wall in an S-shaped path.
And S6, circulating to and fro, enabling the trolley to continuously advance, detecting whether an obstacle exists in front through the ultrasonic sensor, and informing the control system to cut off the advance of the trolley by the ultrasonic sensor before the trolley collides with the obstacle in front to finish polishing.
