DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 The utility model is described in further detail.

[0027] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 The utility model provides an embodiment: a wind power tower end surface processing device, including a tower body 1, a mounting seat 2 is placed on one side of the inner cavity of the tower body 1, a support assembly 3 is arranged between the outer side of the mounting seat 2 and the inner wall of the tower body 1, and the support assembly 3 includes four groups of first electric push rods 301, the four groups of first electric push rods 301 are respectively fixedly mounted on the outer side of the mounting seat 2, and the output ends of the four groups of first electric push rods 301 are all fixedly mounted with arc-shaped support blocks 302, and the ends of the four groups of arc-shaped support blocks 302 away from the mounting seat 2 are in contact with the inner side of the tower body 1. The first electric push rod 301 is telescopic to drive the arc-shaped support block 302 to move until the outer side of the arc-shaped support block 302 is in contact with the inner side of the tower body 1, so that the mounting seat 2 can be fixed in the tower body 1 of different specifications, thereby improving the universality of the device.

[0028] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2The four groups of arc-shaped support blocks 302 are fixedly connected to the rubber pad 4 at one end away from the mounting seat 2. The rubber pad 4 increases the friction between the arc-shaped support block 302 and the tower body 1, thereby making the mounting seat 2 more firmly fixed in the inner cavity of the tower body 1.

[0029] Please refer to the attached figure in the instruction manual Figure 2 and Figure 3 A battery 12 is installed in the inner cavity of the mounting base 2, a driving motor 5 is fixedly installed on the surface of the mounting base 2, a second electric push rod 6 is installed at the power output end of the driving motor 5, a bearing plate 7 is installed at the output end of the second electric push rod 6, a translation component 8 is arranged on the top of the bearing plate 7, a stepping motor 9 is installed on the top of the translation component 8, a groove body 14 is installed at the power output end of the stepping motor 9, and a protrusion 15 is inserted into the end of the groove body 14 close to the tower body 1.

[0030] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 The end of the protrusion 15 away from the stepper motor 9 is fixedly connected with the drill bit 10, and the translation assembly 8 includes two groups of vertical plates 804, which are respectively installed at the two ends of the top of the bearing plate 7. A servo motor 803 is installed on the inner side of the right vertical plate 804, and a screw rod 802 is installed on the power output end of the servo motor 803. The end of the screw rod 802 away from the vertical plate 804 is rotatably connected to the inner side of the left vertical plate 804 through a bearing. The outer wall of the screw rod 802 is threadedly connected with a nut 801, and the top of the nut 801 is fixedly connected to the bottom of the stepper motor 9. When the servo motor 803 is working, it drives the screw rod 802 to rotate, and the rotation of the screw rod 802 drives the nut 801 to move, and when the nut 801 moves, it drives the stepper motor 9 to move left and right, so that the lateral position of the drill bit 10 can be adjusted.

[0031] Please refer to the attached figure in the instruction manual Figure 2 A limiting assembly 11 is provided between the nut 801 and the carrier plate 7. The limiting assembly 11 includes a limiting block 1101, which is fixedly mounted at the bottom of the nut 801. A limiting groove 1102 is provided at the top of the carrier plate 7. The limiting block 1101 is slidably connected to the limiting groove 1102. When the nut 801 moves, the limiting block 1101 can be driven to slide in the limiting groove 1102, thereby limiting the nut 801 and preventing the nut 801 from rotating.

[0032] Please refer to the attached figure in the instruction manual Figure 3 The top and bottom of the groove body 14 are both threadedly connected with locking bolts 13, and the top and bottom of the protrusion 15 are both provided with screw holes 16 that match the locking bolts 13. The locking bolts 13 are screwed into the corresponding screw holes 16, so that the protrusion 15 can be locked and fixed by the locking bolts 13, so that the groove body 14 and the protrusion 15 are more firmly connected.

[0033] Working principle: When the device is used, the battery 12 provides a power source for the entire device, and the controller controls the first electric push rod 301 to extend. The extension of the first electric push rod 301 drives the arc support block 302 to move outward until the outer side of the arc support block 302 abuts against the inner side of the tower body 1, which is used to fix the mounting base 2. At the same time, the friction between the arc support block 302 and the tower body 1 is increased by the setting of the rubber pad 4, so as to avoid the arc support block 302 from sliding.

[0034] Then, the controller controls the second electric push rod 6 to extend, and the second electric push rod 6 extends to drive the supporting plate 7 to move until the drill bit 10 moves to the end face of the tower body 1. Then, the controller starts the stepper motor 9, and the stepper motor 9 drives the drill bit 10 to rotate when working, so as to perform drilling work on the end face of the tower body 1.

[0035] At the same time, the servo motor 803 is started through the controller. When the servo motor 803 is working, it drives the screw rod 802 to rotate. The screw rod 802 rotates to drive the nut 801 to move to the left. When the nut 801 moves, it drives the limit block 1101 to slide in the limit groove 1102, so that the nut 801 can be limited to prevent the nut 801 from rotating. The movement of the nut 801 drives the stepper motor 9 to move to the left, and the staff does not need to use a handheld drilling machine to drill, thereby improving the drilling efficiency of the end face of the tower body 1.

[0036] When the drill bit 10 is damaged after long-term use, the staff will unscrew the locking bolt 13 from the screw hole 16 to release the fixing effect of the locking bolt 13 on the protrusion 15, and then pull the drill bit 10 to the left, and the drill bit 10 drives the protrusion 15 to move to the left until the protrusion 15 is separated from the groove body 14, so that the drill bit 10 can be disassembled and replaced conveniently without replacing the entire device, thereby reducing the maintenance cost of the device.

[0037] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
