Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, this utility model provides a hydraulic lifting device for the steel inner cylinder of a waste incineration power plant chimney, including a steel inner cylinder 2. The steel inner cylinder 2 is provided with a compression fixing assembly, a second support plate 5, a first telescopic unit 6, a base plate 7, and a support rod 10. Multiple first telescopic units 6 are fixed to the top of the base plate 7. The end of the first telescopic unit 6 away from the base plate 7 is connected to the second support plate 5. The top of the second support plate 5 is fixedly connected to the support rod 10. Multiple compression fixing assemblies are fixedly connected to the support rod 10. The compression fixing assemblies abut against the inner wall of the steel inner cylinder 2.

[0024] In this embodiment, the compression fixing assembly includes a compression rod 1, a guide fixing plate 3, a first support plate 4, a second telescopic unit 12, a hinge plate 9, a pressure rod 11, an abutment joint 13, and a connecting rod 14. The first support plate 4 and the guide fixing plate 3 are fixedly connected to the support rod 10. The guide fixing plate 3 is located above the first support plate 4. Multiple connecting rods 14 are provided between the first support plate 4 and the guide fixing plate 3. Multiple through holes are provided on the guide fixing plate 3. The second telescopic unit 12 is fixedly connected to the first support plate 4. The second telescopic unit 12 is located away from the first support plate. One end of the support rod 4 passes through the through hole on the guide fixing plate 3 and is connected to the pressure rod 11. A hinge plate 9 is also fixedly connected to the support rod 10. The hinge plate 9 is provided with multiple hinge interfaces around its circumference. The two ends of the pressure rod 11 are respectively hinged to one end of the two extrusion rods 1. The ends of the two extrusion rods 1 away from the pressure rod are respectively hinged to the hinge interface and the abutment 13. The guide fixing plate 3 can be replaced with a circular plate with a diameter close to that of the inner diameter of the steel inner cylinder 2. At the same time, a track can be set to ensure that the abutment 13 can slide horizontally above the guide fixing plate 3. The first support plate 4 is mainly used to support the second telescopic unit 12.

[0025] In this embodiment, the first support plate 4, the guide fixing plate 3, and the second support plate 5 are all circular plates.

[0026] In this embodiment, the extrusion rod 1 is provided with an extrusion chamber 1.1, and a top plate 1.5 is slidably connected inside the extrusion chamber 1.1. One side of the top plate 1.5 abuts against one end of the pressure rod 11, and a guide rod 1.3 is provided on the side of the top plate 1.5 away from the pressure rod 11. A spring 1.2 is sleeved on the guide rod 1.3, one end of the spring 1.2 is connected to the top plate 1.5, and the other end abuts against the inner wall of the extrusion chamber 1.1. Two guide grooves 1.4 are also correspondingly provided on the extrusion rod 1.4. Both ends are provided with protrusions. The pressure rod 11 is slidably connected to the guide groove 1.4 on the extrusion rod 1 through the protrusions. At the same time, the extrusion rod 1 is provided with a connecting hole in the direction perpendicular to the guide groove 1.4. When in use, the pressure rod 11 presses down to drive the top plate 1.5 to move, and at the same time, the spring 1.2 is compressed. When the compression stops when the guide rod 1.3 abuts against the inner wall of the extrusion chamber 1.1, the guide rod 1.3 and the inner wall of the extrusion chamber 1.1 ensure that the extrusion rod 1 as a whole can stably extrude the abutment 13, ensuring the fixation of the steel inner cylinder 2.

[0027] In this embodiment, a rubber column 15 is provided at one end of the abutment 13 near the inner wall of the steel inner cylinder 2. A magnet can also be provided inside the rubber column 15 to ensure that the abutment 13 is perpendicular to the axial direction of the steel inner cylinder 2 before abutment. At the same time, the rubber column 15 can also prevent damage to the steel inner cylinder 2.

[0028] In this embodiment, the bottom end of the base plate 7 is also provided with a plurality of rollers 8, which make it easier to move the lifting device.

[0029] In this embodiment, both the first telescopic unit 6 and the second telescopic unit 12 are hydraulic telescopic rods, with the hydraulic telescopic rods serving as the main power source.

[0030] Working principle: In use, the second telescopic unit 12 first controls the pressure rod 11 to descend. Under the action of the guide fixing plate 3, the pressing rods 1 on both sides of the pressure rod 11 are pressed down and opened, reducing the distance between the abutment 13 and the inner wall of the steel inner cylinder 2. Then, the entire lifting device is placed inside the steel inner cylinder 2. The second telescopic unit 12 drives the pressure rod 11 to press down, so that the abutment 13 abuts against the inner wall of the steel inner cylinder 2. After multiple abutments 13 abut against each other, the first telescopic unit 6 is activated, so that the lifting device drives the entire steel inner cylinder 2 to rise. At the same time, the rollers 8 can move the steel inner cylinder 2 to the designated position. Since the lifting device is set inside the steel inner cylinder 2, it is convenient to weld from the outside during welding, making welding more convenient.
