A driving groove is opened inside the lifting seat 51. Two-way screw rods 52 are rotatably connected on both sides of the lifting seat 51. A bevel gear 1 53 is fixedly connected in the middle of the two-way screw rod 52. A motor 54 is fixedly installed in the middle of the front end surface of the lifting seat 51. A rotating rod is fixedly connected to the output end of the motor 54. The rotating rod extends into the driving groove and the end is fixedly connected to a bevel gear 2 55. The bevel gear 2 55 is meshed and connected to the bevel gear 1 53. The front and rear ends of both sides of the lifting seat 51 are fixedly connected Guide rod 56, both sides of the bidirectional screw rod 52 are threadedly connected with L-shaped card plates 57, and through holes are opened at the front and rear ends of the L-shaped card plate 57. The guide rod 56 is inserted into the through holes, and the motor 54 is used to drive the bevel gear 2 55 to rotate, and then drive the meshing bevel gear 1 53 to rotate, thereby driving the bidirectional screw rod 52 to rotate, and the bidirectional screw rod 52 drives the L-shaped card plates 57 on both sides to move outward synchronously. At this time, the L-shaped card plate 57 slides on the guide rod 56, which is convenient for adapting to furnace doors and furnace covers of different sizes. The guide rod provides support for the L-shaped card plate 57, making it more stable during hoisting.

[0039] A furnace cover 6 is provided in the middle of the bottom of the clamping structure 5, and slots 61 matching the L-shaped clamping plate 57 are provided on both sides of the furnace cover 6. Fixed plates are fixedly connected to the front and rear ends of both sides of the furnace cover 6, and an L-shaped limiting rod 62 is fixedly connected to the bottom of the fixed plate. The furnace cover 6 is clamped and fixed by using the L-shaped clamping plate 57 to be clamped into the slot 61.

[0040] A stabilizing structure 7 is provided at the front and rear ends of the top of both sides of the combustion furnace 2. The stabilizing structure 7 includes a fixing seat 71 fixedly connected to the front and rear ends of the top of both sides of the combustion furnace 2. A rotating shaft is rotatably connected between the fixing seats 71. A U-shaped fixing block 72 is rotatably connected to the fixing seat 71 through the rotating shaft. The U-shaped fixing block 72 is fixedly connected to a limiting block 73 on the side away from the rotating shaft. A limiting hole 74 is provided on the limiting block 73. Before hoisting the furnace cover 6, the U-shaped fixing block 72 is rotated to open the U-shaped fixing block 72 to facilitate the installation of the furnace cover 6. The U-shaped fixing block 72 is used to limit and fix the L-shaped limiting rod 62, which is convenient for limiting the furnace cover 6 and reduces the possibility of the furnace cover 6 being separated from the surface of the combustion furnace 2 when the equipment is in use.

[0041] A locking structure 8 is provided on one side of the stabilizing structure 7, and the locking structure 8 includes a groove 81 opened on the side of the fixing seat 71 away from the combustion furnace 2, and the top and bottom of the inner wall of the groove 81 are fixedly connected with a sliding rod 82, and a spring 83 is fixedly sleeved on the outer side of the sliding rod 82, and a pull plate 84 is slidably connected to the sliding rod 82, and the pull plate 84 is fixedly connected to the top of the spring 83, and a locking rod 85 is fixedly connected to the top of the pull plate 84, and the locking rod 85 is used in conjunction with the limiting hole 74, and the spring 83 is used to drive the pull plate 84 to slide on the sliding rod 82, so that the locking rod 85 is inserted into the limiting hole 74, and then the U-shaped fixing block 72 is locked, so that the U-shaped fixing block 72 limits and fixes the L-shaped limiting rod 62, which is convenient for limiting the furnace cover 6.

[0042] When the utility model is implemented in practice, before the furnace cover 6 is hoisted, the pull plate 84 is first pulled downward to disengage the locking rod 85 from the limiting hole 74, and then the U-shaped fixing block 72 is rotated to open the U-shaped fixing block 72, and then the motor 54 is started to drive the bidirectional screw rod 52 to rotate, and the bidirectional screw rod 52 drives the L-shaped clamping plates 57 on both sides to move outward synchronously, and at this time the L-shaped clamping plates 57 slide on the guide rods 56, so that the L-shaped clamping plates 57 move to both sides of the furnace cover 6, and then the motor 54 is started to reverse, so that the L-shaped clamping plates 57 move inward and gradually clamp into the clamping groove 61, so as to adapt to furnace doors and furnace covers 6 of different sizes. At the same time, the guide rod also provides support for the L-shaped clamping plate 57, so that the furnace cover 6 is more stable during hoisting and prevents the furnace cover 6 from falling. Then, the cylinder 4 is started to drive the furnace cover 6 to move down and install the furnace cover 6 on the combustion furnace 2. At this time, the L-shaped limit rod 62 is located on both sides of the top of the combustion furnace 2. Then, the pull plate 84 is pulled downward and the U-shaped fixing block 72 is rotated to close it, so that the U-shaped fixing block 72 limits the L-shaped limit rod 62. Then, the pull plate 84 is released, and under the elastic action of the spring 83, the locking rod 85 is inserted into the limiting hole 74 to complete the limiting fixation of the furnace cover 6, effectively stabilize the furnace cover 6, and improve the safety of equipment use.
