At the same time, the first hydraulic cylinder is started to extend its piston rod. The extended first hydraulic cylinder will apply a backward oblique thrust to the mounting frame. At this time, the casting furnace body rotating on the top of the mounting seat will flip with the second rotating pin below the mounting frame as the center of the circle. When the mounting frame is pushed from the horizontal to the vertical state, the casting furnace body is adjusted to the horizontal and continues to rotate forward and backward.

[0017] 2. When the present invention is used, in daily use of the casting furnace body, the second motor is started regularly to drive the screw to rotate. When the screw rotates, it will drive the lifting platform to rise and fall vertically. In this process, the infrared rangefinder, infrared thermometer and gas concentration sensor are driven to detect the outside of the rotating casting furnace body. The infrared rangefinder can determine whether the casting furnace body is deformed or shaking by detecting the distance change on the surface of the casting furnace body. The infrared thermometer detects the temperature of different areas on the surface of the casting furnace body, thereby obtaining the temperature distribution data of the entire furnace surface, and can intuitively find abnormal temperature areas. The gas concentration sensor is used to detect the concentration of harmful gases leaking from the furnace body. The three work together to effectively ensure the safety of the working environment and eliminate safety hazards.

[0018] 3. When the present invention is used, the second hydraulic cylinder is started to control the extension of the piston rod, which will form an oblique thrust forward and upward on the position near the middle of the rotating plate. At this time, the rotating plate will flip backward with the first rotating shaft as the center after being pushed, and drive the bottom furnace cover to move away from the top of the casting furnace body. By controlling the contraction of the second hydraulic cylinder, the furnace cover can be mobilized to press on the top of the casting furnace body to complete the closing. The entire operation does not require manual participation. For large casting furnace bodies, the operation difficulty is relatively low, which improves the use effect.

[0030] In this embodiment, the casting furnace body 301 is rotatably connected to the mounting seat 206 and the top plate 209 through two bearings on the surface, so the casting furnace body 301 can rotate on the top of the mounting seat 206, and the third rotating seat 202 at the bottom of the mounting frame 201 and the second rotating seat 112 at the top of the first support frame 111 are rotatably connected through the second rotating pin 203, so the casting furnace body 301 can be rotated with the second rotating pin 203 as the rotation axis and then converted into a tilted state, the fourth rotating seat 204 and the first rotating head 110 are rotatably connected through the third rotating pin 205, and the first rotating seat 107 is welded to the inner wall of the base frame 101 and is connected to the first rotating seat 107 through the first rotating pin 205.

The hydraulic cylinder that controls the whole casting furnace is operated. When the surface of the casting furnace body 301 needs to be maintained and repaired, the first motor 306 is started to drive the worm 305 to rotate. During the rotation of the worm 305, the casting furnace body 301 between the mounting seat 206 and the top plate 209 is driven to rotate repeatedly through the worm gear 303. During this process, the first hydraulic cylinder 109 can be started at the same time to control the extension of the piston rod. The extended first hydraulic cylinder 109 will generate a backward oblique thrust on the mounting frame 201. At this time, the casting furnace body 301 rotating on the top of the mounting seat 206 will follow the mounting frame 201 and flip over with the second rotating pin 203 below as the center. When the mounting frame 201 is turned After the horizontal state is pushed to the vertical state, the casting furnace body 301 is adjusted to a horizontal state and continuously rotates forward and backward. The staff only needs to move a distance on the ground that is the same as the height of the casting furnace body 301 to complete the maintenance and inspection of the casting furnace body 301. There is no need to climb up and down or go around the casting furnace body 301, which greatly reduces the difficulty of maintenance and inspection and reduces manpower and material costs.

[0032] In this embodiment, during daily use, the casting furnace body 301 regularly starts the second motor 403 to drive the screw 404 to rotate. When the screw 404 rotates, it drives the lifting platform 405 to rise and fall vertically. During the process, it drives the infrared rangefinder 408, the infrared thermometer 409 and the gas concentration sensor 410 to detect the outside of the rotating casting furnace body 301. The infrared rangefinder 408 can determine whether the casting furnace body 301 is deformed or shaken by detecting the distance change on the surface of the casting furnace body 301. The infrared thermometer 409 can determine whether the casting furnace body 301 is deformed or shaken by detecting the distance change on the surface of the casting furnace body 301. The temperature can be detected to obtain the temperature distribution data of the entire furnace surface, and the temperature abnormality area can be found intuitively. The gas concentration sensor 410 detects the concentration of harmful gases leaking from the furnace body. Under mutual cooperation, it can effectively ensure the safety of the working environment and eliminate safety hazards. After the electric push rod 406 is started, it can push the moving plate 407 back and forth to change the distance between the infrared rangefinder 408, the infrared thermometer 409 and the gas concentration sensor 410 and the surface of the rotating casting furnace body 301. When an abnormality is found, the temperature and deformation state are detected at close range to ensure the accuracy of the detection results.

[0033] Example 3: Figures 1-4 and Figure 6As shown, the sealing mechanism 5 includes a rotating plate 501, and the outer surfaces of both sides of the rotating plate 501 near the front side are fixedly connected to the first rotating shaft 503, the outer surfaces of the two first rotating shafts 503 are rotatably connected to the first rotating frame 502, and the two first rotating frames 502 are fixedly connected to the top of the top plate 209 near the front side, and the bottom of the rotating plate 501 is provided with a furnace cover matching the casting furnace body 301, and the outer surfaces of both sides of the rotating plate 501 near the middle are fixedly connected to the second rotating shaft 504, and the outer surfaces of the two second rotating shafts 504 are rotatably connected to the inclined first rotating blocks 505, and the rear surfaces of the two first rotating blocks 505 are installed with second hydraulic cylinders 506, and the rear ends of the second hydraulic cylinders 506 are installed with second rotating blocks 507, and the outer surface of the second rotating block 507 is rotatably connected to the second rotating frame 508, and the second rotating frame 508 is fixedly connected to the top of the top plate 209 near the rear side.

[0034] In this embodiment, the rotating plate 501 is rotatably connected to the top plate 209 by cooperating with the first rotating frame 502 and the first rotating shaft 503, so that the rotating plate 501 can rotate with the first rotating shaft 503 as the center of the circle. The top of the second hydraulic cylinder 506 is rotatably connected to the rotating plate 501 by cooperating with the second rotating shaft 504 and the first rotating block 505. The second hydraulic cylinder 506 is rotatably connected to the top of the top plate 209 by cooperating with the second rotating block 507 and the second rotating frame 508. When in use, by starting After the second hydraulic cylinder 506 controls the piston rod to extend, it can form a forward and upward oblique thrust on the rotating plate 501 near the middle position. At this time, after being pushed, the rotating plate 501 will flip backward with the first rotating shaft 503 as the center and drive the bottom furnace cover to move away from the top of the casting furnace body 301. By controlling the contraction of the second hydraulic cylinder 506, the furnace cover can be mobilized to press on the top of the casting furnace body 301 to complete the closing. The entire operation does not require manual operation, and it is less difficult to operate a large casting furnace body 301, thereby improving the use effect.

[0035] The effect and working principle achieved by the entire mechanism are as follows: when the surface of the casting furnace body 301 is maintained and inspected, the first motor 306 is started to drive the worm 305 to rotate. During the rotation of the worm 305, the worm gear 303 is used to cause the casting furnace body 301 between the mounting seat 206 and the top plate 209 to rotate repeatedly. At the same time, the first hydraulic cylinder 109 can also be started to extend its piston rod. The extended first hydraulic cylinder 109 will apply a backward oblique thrust to the mounting frame 201. At this time, the casting furnace body 301 rotating on the top of the mounting seat 206 will follow the mounting frame 201 and rotate with the second rotating pin 203 below as the rotation axis to form an inclined state. When the mounting frame 201 is pushed from the horizontal state to the vertical state, the casting furnace body 301 is adjusted to a horizontal and continuously reverse rotating state. The staff only needs to move a distance on the ground at the same height as the casting furnace body 301 to complete the casting furnace body 301. The maintenance and inspection work of the casting furnace body 301 does not need to be climbed up and down or walked around, which greatly reduces the difficulty of maintenance and inspection and saves manpower and material costs. In addition, in the daily use of the casting furnace body 301, the second motor 403 is started regularly to drive the screw rod 404 to rotate. When the screw rod 404 rotates, it will drive the lifting platform 405 to rise and fall vertically. In this process, the infrared rangefinder 408, the infrared thermometer 409 and the gas concentration sensor 410 are driven to detect the outside of the rotating casting furnace body 301. The infrared rangefinder 408 can determine whether the casting furnace body 301 is deformed or shaken by detecting the distance change on the surface of the casting furnace body 301. The infrared thermometer 409 detects the temperature of different areas on the surface of the casting furnace body 301, thereby obtaining the temperature distribution data of the entire furnace surface, and can intuitively find the temperature abnormal area. The gas concentration sensor 410 It is used to detect the concentration of harmful gases leaking from the furnace body. The three work together to effectively ensure the safety of the working environment and eliminate safety hazards. At the same time, starting the second hydraulic cylinder 506 to control the extension of the piston rod will form a forward and upward oblique thrust on the rotating plate 501 near the middle. At this time, after being pushed, the rotating plate 501 will flip backward with the first rotating shaft 503 as the center of the circle, and drive the bottom furnace cover to move away from the top of the casting furnace body 301. By controlling the contraction of the second hydraulic cylinder 506, the furnace cover can be mobilized to press on the top of the casting furnace body 301 to complete the closing. The entire operation does not require manual participation. For large casting furnace bodies 301, the operation difficulty is relatively low, which improves the use effect.
