[0014] Step 1: The device is placed into the kiln through the bottom opening. The hydraulic cylinder lifts the upper ring, and the push assembly on the upper ring works to press against the kiln inner wall to fix the upper ring in place. The hydraulic cylinder retracts, pulling up the lower ring. The push assembly on the lower ring expands outward to press against the kiln inner wall. The push assembly on the upper ring retracts, and the hydraulic cylinder lifts up the upper ring. This cycle drives the upper and lower rings to move to the position on the kiln inner wall that needs repair, and the repair position is between the upper and lower rings.

When the anchor on the chuck of the welding assembly touches the inner wall of the kiln, the circuit is closed, and the anchor is welded to the inner wall of the kiln.

[0017] Step 4: The steering motor drives the sleeve to rotate on the vertical rod, so that the spraying mechanism is aligned with the repair position. The electric push drives the material gun to advance into the inner wall of the kiln. The material pump works to draw the spray material into the material gun. The compressed gas is input into the material gun through the air supply pipe. During the spraying process, the direction of the material gun is controlled by the rotation of the sleeve. The distance between the material gun and the inner wall of the kiln is controlled by the electric push rod and the telescopic assembly. The height of the material gun is controlled by the second hydraulic cylinder.

[0018] Step 5. After the repair material is sprayed, the steering motor drives the sleeve to rotate on the vertical rod so that the drying mechanism is aligned with the repair position. The baking lamp is turned on to dry the repair position. The fan works to blow away the water vapor overflowing from the repair position during the drying process and discharge it through the tubular cloth bag.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are:

[0030] The mounting frame 6 includes a connecting rod 61, a frame 62, a guide rail 63, a block assembly 64, a movable plate 65, a driving motor 66, a roller 67, a pull rope 68 and a telescopic assembly 69. The outer wall of the sleeve 15 is fixedly connected to the frame 62 through the connecting rod 61. The frames 62 in the four mounting frames 6 are spliced ​​into a rectangle. The frame 62 is vertically installed with a guide rail 63 on the side away from the connecting rod 61. The movable plate 65 is slidably connected to the guide rail 63. The bottom end of the mounting plate 11 is provided with a block assembly 64 for limiting the movable plate 65. The top of the frame 62 is fixedly installed with a driving motor 66. One end of the pull rope 68 is fixedly connected to the roller 67 installed at the output end of the driving motor 66. The other end of the pull rope 68 is fixedly connected to the top of the movable plate 65. The movable plate 65 is away from the frame 62. A telescopic assembly 69 is provided on the side.

[0031] The stopper assembly 64 includes an electromagnet 641, a guide tube 642, a stopper 643, a limit block 644 and a limit spring 645.

[0032] The four mounting frames 6 are respectively provided with a breaker hammer 17, a welding mechanism 7, a spraying mechanism 8 and a drying mechanism 9 for repairing the lining of the kiln wall. The steering motor 16 drives the sleeve 15 to rotate and switch the breaker hammer 17, the welding mechanism 7, the spraying mechanism 8 and the drying mechanism 9 to process the repair surface of the kiln wall respectively. For technicians in this technical field, using a breaker hammer 17 to clean the residual lining of the kiln inner wall is a well-known technology, and using a buffer structure to buffer the vibration generated by the breaker hammer 17 on the installation surface when it is working is also a conventional choice and will not be elaborated.

[0033] The welding mechanism 7 includes a discharge box 71, a welding assembly 72 and a three-axis robotic arm 73. The discharge box 71, the welding assembly 72 and the three-axis robotic arm 73 are all installed on the telescopic assembly 69. The discharge box 71 is used to place anchors.

Here, the metal anchor serves as a welding rod, and the contact point between the chuck of the welding component 72 and the technical anchor can be detached by shaking the welding component 72. Compared with the traditional welding method, that is, using a welding rod to weld the anchor and the inner wall of the kiln, the method adopted by this technical solution is more convenient and more suitable for narrow working environments.

[0035] The drying mechanism 9 includes a light guide cover 91, a baking lamp 92 and an air hole 93. The light guide cover 91 is fixedly installed on the telescopic component 69. The inner wall of the light guide cover 91 points to the side away from the telescopic component 69. The baking lamp 92 is installed in the middle of the inner wall of the light guide cover 91. The upper and lower walls of the light guide cover 91 are provided with air holes 93.

[0036] When this device is working, it includes the following steps:

[0037] Step 1: The device is placed into the vertical kiln through the bottom opening. The hydraulic cylinder 3 lifts the upper ring 1. The propulsion assembly 4 on the upper ring 1 works to press against the inner wall of the kiln to fix the position of the upper ring 1. The hydraulic cylinder 3 retracts, pulling up the lower ring 2. The propulsion assembly 4 on the lower ring 2 expands outward to press against the inner wall of the kiln. The propulsion assembly 4 on the upper ring 1 retracts, and the hydraulic cylinder 3 lifts up the upper ring 1. This cycle drives the upper ring 1 and the lower ring 2 to move to the position on the inner wall of the kiln that needs to be repaired. The repair position is between the upper ring 1 and the lower ring 2. The image sensor 18 transmits the image of the rising process to the operator in real time:

[0038] Step 2: The steering motor 16 drives the sleeve 15 to rotate on the vertical rod 13, so that the breaker 17 is aligned with the position to be repaired. The telescopic assembly 69 is extended to move the breaker 17 close to the inner wall of the kiln. The breaker 17 removes and trims the remaining lining of the kiln inner wall, and the crushed waste is discharged through the tubular cloth bag 19;

[0039] Step 3: The steering motor 16 drives the sleeve 15 to rotate on the vertical rod 13, so that the welding mechanism 7 is aligned with the repair position. The pre-made anchor is placed in the discharge box 71. The three-axis robot arm 73 grabs the anchor from the discharge box 71 and places it on the clamp of the welding assembly 72. The telescopic assembly 69 pushes the welding assembly 72 into the inner wall of the kiln. The contact of the welding assembly 72 contacts the inner wall of the vertical kiln. When the anchor on the clamp of the welding assembly 72 contacts the inner wall of the kiln, the circuit is closed, and the anchor is welded to the inner wall of the kiln.

[0040] Step 4: The steering motor 16 drives the sleeve 15 to rotate on the vertical rod 13, so that the spraying mechanism 8 is aligned with the repair position. The electric push 81 drives the material gun 82 to advance into the inner wall of the kiln. The material pump 84 works to draw the spraying material into the material gun 82. The compressed gas is input into the material gun 82 through the air supply pipe 85. During the spraying process, the direction of the material gun 82 is controlled by the rotation of the sleeve 15. The distance between the material gun 82 and the inner wall of the kiln is controlled by the electric push rod 81 and the telescopic assembly 69. The height of the material gun 82 is controlled by the hydraulic cylinder 12.

[0041] Step 5. After the repair material spraying is completed, the steering motor 16 drives the sleeve 15 to rotate on the vertical rod 13, so that the drying mechanism 9 is aligned with the repair position, the baking lamp 92 is turned on to dry the repair position, and the fan 20 works to blow away the water vapor overflowing from the repair position during the drying process and discharge it through the tubular cloth bag 19.

The distance between the material gun 82 and the inner wall of the kiln is controlled by the electric push rod 81 and the telescopic assembly 69. The height of the material gun 82 is controlled by the hydraulic cylinder 12. Step 5. After the repair material spraying is completed, the steering motor 16 drives the sleeve 15 to rotate on the vertical rod 13, so that the drying mechanism 9 is aligned with the repair position, the baking lamp 92 is turned on to dry the repair position, and the fan 20 works to blow away the water vapor overflowing from the repair position during the drying process and discharge it through the tubular cloth bag 19.
