DETAILED DESCRIPTION
[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0017] Example 1 See also Figure 1-4 A rotary kiln lining repair device includes a rotary kiln body 1, a fixed base 5 and a support plate 15. A fixing mechanism is provided above the fixed base 5. The support plate 15 is connected to the fixing mechanism. The fixing mechanism is used to fix the position of the support plate 15 in the rotary kiln body 1. A roller brush 17 is connected to the support plate 15. The roller brush 17 is used to apply paint to the surface of the repair material.
[0018] One side of the roller brush 17 is provided with an adapter mechanism for guiding, see the attached Figure 1 The position of the roller brush 17 should correspond to the repair area 2 in the rotary kiln body 1, and the inner wall of the rotary kiln body 1 that the sliding roller 28 contacts should be intact. The roller brush 17 is brushed along the inner wall of the rotary kiln body 1 using the intact inner wall as a reference.
[0019] The adapting mechanism includes an adjusting frame 18, a mounting plate 22 is connected to the adjusting frame 18, an extension block 27 is connected to the mounting plate 22 in a telescopic manner, and a sliding roller 28 is provided on the extension block 27. The extension block 27 extends to contact with the side wall of the repair side of the rotary kiln body 1 and then moves to drive the roller brush 17 to apply paint to the surface of the repair material. The end of the roller brush 17 that applies paint should be closer to the inner wall of the rotary kiln body 1 relative to the sliding roller 28. This method can ensure that the roller brush 17 can contact the position of the repair area 2 and has a strength that will not affect the repair material.
[0020] Example 2 The adjustment frame 18 is also provided with a lifting group for adjusting the height of the sliding roller 28 , and the height of the mounting plate 22 should correspond to the position of the repair area 2 .
[0021] The lifting group includes a lifting shaft 19 arranged outside the adjustment frame 18, a lifting block 21 is slidably connected inside the adjustment frame 18, an inner side wall of the adjustment frame 18 is slidably connected to a mounting plate 22, and a sliding opening 20 is opened on the side wall of the adjustment frame 18 on the side opposite to the lifting shaft 19; The lifting block 21 passes through the sliding opening 20 and extends in the direction of the lifting block 21 . The lifting block 21 is connected to the lifting shaft 19 by threads, and the lifting shaft 19 can be rotated manually.
[0022] See attached Figure 4 , first determine the position of the repair area 2, and rotate the lifting shaft 19. The lifting shaft 19 will drive the lifting block 21 to move downward under the action of the thread until the position of the mounting plate 22 corresponds to the position of the repair area 2. It should be noted that the rotary kiln body 1 is a flat cylindrical setting. When the repair area 2 is above the center of the rotary kiln body 1, the height of the mounting plate 22 is controlled by the lifting group to correspond to the height of the repair area 2. When the repair area 2 is below the center of the rotary kiln body 1, the fixing spring 23 needs to be removed, and the lifting block 21 is at a position higher than the repair area 2. Then, the height of the mounting plate 22 when it is in the rotary kiln 2 is controlled by controlling the extension length of the extension block 27. At this time, the roller brush 17 is close to the bottom of the repair area 2.
[0023] The lifting block 21 and the mounting plate 22 are arranged in an upper and lower manner in the adjusting frame 18, and a third telescopic rod 24 is provided between the two. A fixing spring 23 is provided between the mounting plate 22 and the inner wall of the adjusting frame 18. The fixing spring 23 should be detachably arranged between the two. The fixing spring 23 is used to make the mounting plate 22 stick to the bottom of the lifting block 21 when the mounting plate 22 is not subjected to force.
[0024] A driving motor 25 is fixedly connected to the mounting plate 22, and an output shaft 26 is fixedly connected to the output end of the driving motor 25. The output shaft 26 extends into the extension block 27, and the output shaft 26 and the extension block 27 are connected by threads, and the end of the extension block 27 opposite to the inside of the rotary kiln body 1 is connected to the sliding roller 28. When it is necessary to apply paint to the repair material in the repair area 2, the output shaft 26 is driven by the driving motor 25 to rotate, so that the extension block 27 moves relative to the lifting block 21, and during the movement, the roller brush 17 is driven to apply paint to the surface of the repair material.
[0025] The support plate 15 is rotatably connected to the second telescopic rod 16, and the roller brush 17 is connected to the telescopic end of the second telescopic rod 16, wherein the telescopic end of the second telescopic rod 16 is rotatably connected to the extension block 27 via a rotating shaft 29. Figure 3 In this way, the roller brush 17 can be extended and rotated, and can move along with the movement of the sliding roller 28.
[0026] Example 3 This embodiment is a preferred fixing method for the roller brush 17 and the sliding roller 28.
[0027] The fixing mechanism includes a first extension plate 4 fixedly connected to a fixing base 5, a second extension plate 3 is slidably connected inside the first extension plate 4, the first extension plate 4 and the second extension plate 3 are both hollow, the hollow areas inside the first extension plate 4 and the second extension plate 3 are connected, a same fixed shaft 10 is arranged in the area, a fixed motor 9 is arranged at the inner bottom of the first extension plate 4, and the bottom end of the fixed shaft 10 is connected to the output end of the fixed motor 9; A mounting block 8 is provided inside the second extension plate 3, and the mounting block 8 is threadedly connected to the fixed shaft 10, wherein a first bevel gear 11 is provided at the top of the second extension plate 3, and extension cylinders 13 are rotatably connected on opposite sides of the second extension plate 3, and a second bevel gear 12 is provided on one end of the extension cylinder 13 located inside the second extension plate 3, and the second bevel gear 12 will mesh with the first bevel gear 11 after moving up a certain distance.
[0028] The opposite sides of the second extension plate 3 are connected with clamping plates 6 through the first telescopic rod 7 , and the side of the clamping plate 6 opposite to the second extension plate 3 is connected with a clamping shaft 14 , wherein the clamping shaft 14 is threadedly connected to the extension tube 13 .
[0029] The specific implementation of this embodiment is as follows: the fixed motor 9 is controlled to drive the fixed shaft 10 to rotate, and the fixed shaft 10 drives the mounting block 8 and the second extension plate 3 to move upward as a whole under the action of the thread. Synchronously, the two extension tubes 13 will also move upward. When the two clamping plates 6 move to the height of the center line of the rotary kiln body 1, the thread of the mounting block 8 will disengage from the thread on the fixed shaft 10, thereby making the second extension plate 3 at the highest point. When the second extension plate 3 is at the highest point, the first bevel gear 11 will mesh with the second bevel gear 12. At this time, the first bevel gear 11 will drive the second bevel gear 12 to rotate, thereby making the two extension tubes 13 rotate. When the extension tube 13 rotates, the two clamping plates 6 will be driven to move in opposite directions under the action of the thread until the clamping plates 6 move to the two end points of the same diameter of the rotary kiln body 1, thereby fixing the fixing device.
