Description

Technical Field

[0001] The utility model relates to the technical field of hydrogenation reaction equipment, in particular to a hydrogenation reaction tower. Background Art

[0002] Hydrogenation is a reaction process in which hydrogen interacts with other compounds, typically in the presence of a catalyst. A hydrogenation tower is a device used for this reaction. Hydrogenation towers are typically large tank structures that require regular inspections during daily use to ensure safety. Existing climbing ladders on hydrogenation tower tanks are mostly vertical handrails located on one side of the tank. While these ladders assist workers in climbing up and down, the large size of the tank prevents workers from fully observing the situation on the other side of the ladder, significantly reducing inspection effectiveness.

[0003] To address these issues, the utility model with authorization publication number CN220878811U discloses a hydrogenation reactor. This device utilizes a ring-shaped slide bar, a slider, and a movable mechanism to stably attach a climbing frame to the side of the reactor tank. Workers can also use a transmission mechanism to control the climbing frame's movement around the reactor tank, assisting them in reaching any point outside the tank for comprehensive maintenance. However, this device still requires workers to climb and manually circumvent the climbing frame by pulling a transmission belt, which is time-consuming and labor-intensive, and inconvenient to carry maintenance tools, posing a threat to worker safety.

[0030] Example 1

[0031] See also Figures 1 to 7 In an embodiment of the present invention, a hydrogenation reaction tower includes a tower body 1 and a support frame 2. The tower body 1 is erected on the ground through the support frame 2. An annular guide rail 3 is fixedly installed around the bottom of the tower body 1. A self-propelled vehicle 4 is slidably installed on the annular guide rail 3. The self-propelled vehicle 4 can be moved circumferentially along the bottom of the tower body 1 through the annular guide rail 3. Two lifting racks 5 are fixedly installed on the top of the self-propelled vehicle 4, and the bottoms of the two lifting racks 5 are further fixed to the top of the self-propelled vehicle 4 through a reinforcing plate. A lifting platform 6 is slidably installed on the two lifting racks 5, and the lifting platform 6 can move up and down along the lifting racks 5. An annular sliding rod 7 is fixedly installed around the top of the tower body 1. A sliding frame 8 is fixedly installed on the top of the two lifting racks 5 by bolts. An arc-shaped slide groove is provided at the bottom of the sliding frame 8, and the annular sliding rod 7 is located in the arc-shaped slide groove. The lifting rack 5 is slidably connected to the annular sliding rod 7 through the arc-shaped slide groove of the sliding frame 8. The cooperation of the annular sliding rod 7 and the sliding frame 8 allows the self-propelled vehicle 4 to drive the lifting rack 5 in a more stable circular motion, preventing the lifting platform 6 on the lifting rack 5 from shaking after being raised too high. The cooperation of the annular guide rail 3, the self-propelled vehicle 4, the lifting rack 5, the annular sliding rod 7 and the sliding frame 8 allows the lifting platform 6 to carry staff and maintenance tools to any position around the tower body 1, facilitating routine inspection and maintenance of the reaction tower. The fully automatic movement method eliminates the need for staff to climb up by themselves, improving the safety of the device, saving time and effort, and being more convenient and quick.

[0032] The self-propelled vehicle 4 includes a base plate 9, and a self-propelled motor 10 is fixedly installed on both the front and rear sides of the top of the base plate 9, and two lifting racks 5 are fixedly installed on the top of the base plate 9. The self-propelled motor 10 includes a drive motor part and a reducer part, wherein the output shaft of the reducer part passes through the base plate 9 and is fixedly connected to the drive gear 11. Two pulleys 12 are rotatably installed on the left and right sides of the bottom of the base plate 9, and each pulley 12 is slidably installed with the annular guide rail 3. Among them, the top of the two pulleys 12 on the left side of the bottom of the base plate 9 is fixedly sleeved with a driven gear 13, and the two driven gears 13 are meshed and connected with the two driving gears 11. The self-propelled motor 10 drives the driving gear 11 to rotate, and the driving gear 11 drives the driven gear 13 meshed with it to rotate, thereby driving the pulley 12 to rotate, so that the base plate 9 can drive the lifting rack 5 and the lifting platform 6 to move in a circular direction along the annular guide rail 3.

[0033] The lift platform 6 comprises an open-top lift cabin 14 and extension plates 15 fixedly mounted on the left and right sides of the bottom of the cabin 14. A lift motor 16 is fixedly mounted on the bottom of the cabin 14. This motor comprises a drive unit and a reducer unit. The output shafts of the reducer unit are fixedly connected to lift gears 17 on both sides. The outer sides of the two lift gears 17 are rotatably mounted on the inner wall of the extension plate 15. The bottom of the cabin 14 has two through-holes for the lift racks 5 to pass through. The two lift gears 17 mesh with the lift racks 5 on the same side. The lift motor 16 drives the lift gears 17 to rotate, which move along the meshed lift racks 5, thereby driving the entire lift platform 6 up and down. A door 18 is hingedly connected to the front of the cabin 14. A latch 19 is located near the top of the cabin 14 near the door 18. The latch 19 locks the door 18, keeping it closed during operation, ensuring the safety of personnel.
