The output end of the cylinder 12 is rotatably connected to the cylinder 2 13, and the cylinder 2 13 is fixedly connected to the second connecting rod 3. The first connecting rod 2 is rotatably connected to the fourth connecting rod 7, and the second connecting rod 3 is rotatably connected to the third connecting rod 6. When using the protective device for a high-temperature tunnel kiln, when part of the supporting structure of the tunnel kiln needs to be removed or replaced, the design of the arc plate 1 20 and the arc plate 2 22 ensures that the stability of the overall structure is not affected, effectively prevents the risk of kiln collapse caused by maintenance work, and ensures the safety of the maintenance work. At the same time, the opening of the cylinder 12 can be adjusted according to the height of the tunnel kiln support, so that the support plate 4 and the arc plate can adapt to tunnel kilns of different heights, providing flexibility and adaptability.
[0024] The support plate 4 is fixedly connected to a motor 14, and the output end of the motor 14 is fixedly connected to a first bevel gear 15, and the first bevel gear 15 is meshed with a second bevel gear 16, and the second bevel gear 16 is fixedly connected to a threaded screw 17, and the threaded screw 17 is rotatably connected to the support plate 4, and one end of the threaded screw 17 is rotatably connected to a bracket 31, and the bracket 31 is fixedly connected to the support plate 4, and a threaded sleeve 18 is threadedly connected to the threaded sleeve 18, and a fifth connecting rod 19 is rotatably connected to the threaded sleeve 18, and one end of the fifth connecting rod 19 is rotatably connected to an arc plate 1 20, and the arc plate 1 20 is rotatably connected to the bracket 31, and the threaded sleeve 18 is rotatably connected to the sixth connecting rod 21, and one end of the sixth connecting rod 21 is rotatably connected to an arc plate 22, and the arc plate 22 is rotatably connected to the bracket 31. A working basket 23 is fixedly connected to the support plate 4, and a railing 24 is fixedly connected to the working basket 23, and a basket door 25 is rotatably connected to the railing 24. The bottom of the base plate 1 is provided with a universal wheel 29, and a handle 30 is fixedly connected to one side of the base plate 1. There are four groups of universal wheels 29, and the universal wheels 29 have a self-locking function. The clamping column 27 passes through the railing 24, and the clamping column 27 passes through the fixed frame 26. The arc plate 1 20 and the arc plate 2 22 are symmetrically arranged, and the fifth connecting rod 19 and the sixth connecting rod 21 are symmetrically arranged. When using the protective device for the high-temperature tunnel kiln, through the movement of the base plate 1 and the self-locking function of the universal wheel 29, the staff can quickly move the work basket 23 to the position where maintenance is required, and conveniently enter and exit the work basket 23 through the cooperation of the clamping column 27 and the basket door 25, ensuring the safety of the staff during the maintenance process of the high-temperature tunnel kiln and improving the efficiency of maintenance.
[0025] Working principle: When using the high-temperature tunnel kiln protection device, the staff first pushes the handle 30 to move the bottom plate 1 to the place where maintenance is required through the rotation of the four sets of universal wheels 29, and then locks it through the self-locking function of the universal wheels 29. Then the staff pulls the clamping column 27, and the clamping column 27 slides on the fixing frame 26 and the railing 24 by compressing the spring 28 and leaves the basket door 25. After one end of the clamping column 27 leaves the basket door 25, the staff pulls the basket door 25 and rotates on the railing 24, then enters the working basket 23, and then pulls the basket door 25 to reset, and then releases the clamping column 27, which is rebounded by the spring 28. One end of the clamping column 27 is clamped in the hole on the basket door 25 to complete the fixation of the basket door 25, which is convenient for the staff to enter and exit when repairing the high-temperature tunnel kiln. Then the motor 14 is turned on, and the motor 14 drives the first bevel gear 15 to rotate. The first bevel gear 15 drives the second bevel gear 16 to rotate. The second bevel gear 16 drives the threaded screw 17 to rotate on the support plate 4 and the bracket 31. The threaded screw 17 drives the threaded sleeve 18 to move through the threaded connection. The threaded sleeve 18 also drives the fifth connecting rod 19 and the sixth connecting rod 21 to move. The fifth connecting rod 19 and the sixth connecting rod 21 drive the arc plate 1 20 and the arc plate 2 22 to rotate on the bracket 31. When it moves to the desired position, the motor 14 can be turned off, and then the cylinder 12 is turned on. The cylinder 12 pushes the cylinder 2 13 to move, and the cylinder 2 13 drives the second connecting rod 3 to move. At the same time, the first connecting rod 2 rotates on the bottom plate 1, and the second connecting rod 3 drives the support plate 4 to rise. When the support plate 4 rises, it drives the first slider 5 to slide on the second chute 10. The first slider 5 drives the third connecting rod 6 to move, and the third connecting rod 6 drives the fourth connecting rod 7 to move. The fourth connecting rod 7 drives the second slider 8 to slide on the first chute 9, so that the support plate 4 drives the arc plate 1 20 and the arc plate 2 22 to rise. When the arc plate 1 20 and the arc plate 2 22 are attached to the high-temperature tunnel kiln When the support plate 4 is raised, the cylinder 12 can be closed. It is suitable for the maintenance process of the tunnel kiln. When part of the supporting structure is removed or replaced, the arc plate 1 20 and the arc plate 2 22 ensure that the stability of the overall structure is not affected, effectively preventing the risk of kiln collapse caused by maintenance work, and the cylinder 12 can be opened and adjusted according to the height of different tunnel kiln supports. At the same time, the rise of the support plate 4 drives the staff in the working basket 23 to rise synchronously, so that the maintenance personnel can quickly and accurately reach the tunnel kiln area that needs maintenance without manual climbing or the use of other auxiliary equipment, thereby saving time and energy, and thus timely repairing and protecting the tunnel kiln.
