Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pump station unit maintenance, in particular to water conservancy pump station unit maintenance and lifting equipment. Background Art

[0002] Pump stations are common and important facilities in water conservancy projects, used to pump water from low to high locations to meet needs such as farmland irrigation and urban water supply. Pump stations typically integrate pumps, pipelines, control systems, valves, screens, and sewage treatment equipment into a prefabricated cylinder, significantly saving space. This design allows for flexible deployment within limited urban land, while reducing construction time and costs. Pump stations operate in harsh environments for long periods of time, with poor operating conditions and high operating loads, making them prone to equipment failure and potential safety hazards. Therefore, they frequently require repair and maintenance. Prior to repair, the equipment to be repaired must be hoisted using lifting equipment.

[0003] A Chinese patent discloses a lifting device for repairing water pump station units (authorization announcement number CN221165666U). This patented technology improves the stability of lifting and hoisting when lifting units that need repair in the pump station, avoids excessive shaking, and thus facilitates maintenance by staff; ultimately, it can reduce the footprint of the entire lifting device and can also be moved, thereby increasing its scope of application. However, when the pump station environment is restricted, it is impossible to lift the required equipment. Utility Model Content

[0019] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a maintenance and lifting device for a water conservancy pumping station unit includes a lifting frame 1, a lifting power mechanism 2 is installed at the upper end of the lifting frame 1, and a position adjustment mechanism 3 is installed on the front side of the lifting frame 1.

[0020] In Figure 1 and Figure 2 , the lifting frame 1 includes a group of vertical pipes 11 arranged in parallel in the vertical direction. The upper ends of a group of vertical pipes 11 are jointly embedded with a gantry 13, and a group of connecting rods 12 are fixedly connected between a group of vertical pipes 11. An elevating hydraulic cylinder 14 is installed inside each vertical pipe 11, and the output end of each elevating hydraulic cylinder 14 is fixedly connected to the corresponding lower end of the gantry 13. By the telescopic movement of the elevating hydraulic cylinder 14, the gantry 13 is driven to move up and down in the vertical direction, so as to adjust the height of the lifting power mechanism 2 in the vertical direction to meet the requirements of the maintenance of the water conservancy pumping station unit. A balance plate 16 is fixedly connected to the lower end of each vertical pipe 11, a support hydraulic cylinder 17 is installed at the front and rear ends of each balance plate 16, and a group of pulleys 15 are installed between the two support hydraulic cylinders 17 at the lower end of each balance plate 16. When the support hydraulic cylinder 17 contracts, the entire lifting device can be moved to the position where hoisting is required through the pulley 15, and then the support hydraulic cylinder 17 is extended, and the output end of the support hydraulic cylinder 17 is supported on the ground, so that the pulley 15 is separated from the ground, and the entire lifting device can be kept stable.

[0021] In Figure 1 and Figure 3Among them, the lifting power mechanism 2 includes a motor base 25 fixedly installed at the upper end of the lifting frame 1 and a hoisting drum 21. A hoisting motor 24 is installed at the upper end of the motor base 25. A connecting shaft 22 is installed on one side of the hoisting drum 21. A synchronous pulley set 23 is installed between the output end of the hoisting motor 24 and the connecting shaft 22. A steel wire rope 26 is wound around the hoisting drum 21. A hook 27 is installed at the lower end of the steel wire rope 26. The equipment to be repaired in the water conservancy pumping station unit is hooked by the hook 27. Then, the hoisting motor 24 drives the synchronous pulley set 23 to rotate. The synchronous pulley set 23 drives the hoisting drum 21 to rotate through the connecting shaft 22, and the hoisting drum 21 is wound up, so as to lift the equipment to be repaired. Both the motor base 25 and the hoisting drum 21 are fixedly installed at the upper end of the gantry 13, so that the height of the lifting power mechanism 2 can be adjusted by the lifting of the gantry 13 to meet the requirements of the repair of the water conservancy pumping station unit.

[0022] In Figure 1 and Figure 4 Among them, the position adjustment mechanism 3 includes a swing arm 31 rotatably connected to the front side of the lifting frame 1 and a first electric cylinder 32. The upper side of the front end of the swing arm 31 is rotatably connected to an extension arm 33, and the lower side of the front end of the swing arm 31 is rotatably connected to the output end of the first electric cylinder 32. The middle part of the upper end of the swing arm 31 is rotatably connected to a second electric cylinder 37. A roller motor 36 is installed on one side of the upper end of the extension arm 33. The output end of the roller motor 36 is fixedly connected to a roller frame 34. A roller 35 is rotatably connected to the inner side of the roller frame 34. The output end of the second electric cylinder 37 is rotatably connected to the middle part of the extension arm 33. By the extension of the first electric cylinder 32, the swing arm 31 is driven to swing upward at a certain angle with the joint of the swing arm 31 and the lifting frame 1 as the center of the circle, so that the roller 35 moves forward to a certain position; then, by the telescopic movement of the second electric cylinder 37, the extension arm 33 is driven to swing at a certain angle with the joint of the extension arm 33 and the swing arm 31 as the center of the circle to adjust the position of the roller 35, so that the roller 35 is located directly above the equipment to be lifted in the water conservancy pumping station unit. Then, the roller motor 36 drives the roller frame 34 to rotate at a certain angle to finely adjust the position of the roller 35, so that the hook 27 can be conveniently hooked on the equipment to be lifted in the water conservancy pumping station unit; Therefore, even if the position of the water conservancy pumping station is restricted and it is not convenient to move the lifting frame 1 above the equipment to be lifted, the equipment to be repaired can be safely lifted up. The rear ends of the swing arm 31 and the first electric cylinder 32 are respectively rotatably connected to the front end of the connecting rod 12, so as to provide support for the position adjustment mechanism 3 through the connecting rod 12.

[0023] Working principle of the utility model: First, determine the equipment in the water conservancy pump station unit that needs to be repaired. Then, move the entire lifting device to the position where hoisting is required through the pulley 15. Next, start the support hydraulic cylinder 17. The support hydraulic cylinder 17 extends, supports the output end of the support hydraulic cylinder 17 on the ground, and makes the pulley 15 leave the ground;

[0024] Next, pass the steel wire rope 26 in the lifting power mechanism 2 through the front side of the idler roller 35. Start the first electric cylinder 32. The first electric cylinder 32 extends, driving the swing arm 31 to swing upward at a certain angle with the junction of the swing arm 31 and the lifting frame 1 as the center of the circle, so that the idler roller 35 moves forward to a certain position. Then, start the second electric cylinder 37. According to the on-site situation, make the second electric cylinder 37 extend and retract, driving the extension arm 33 to swing at a certain angle with the junction of the extension arm 33 and the swing arm 31 as the center of the circle, adjust the position of the idler roller 35, so that the idler roller 35 is directly above the equipment to be lifted in the water conservancy pump station unit. Then, drive the idler roller frame 34 to rotate at a certain angle through the idler roller motor 36 to finely adjust the position of the idler roller 35, so that the hook 27 can be conveniently hung on the equipment to be repaired in the water conservancy pump station unit;

[0025] Next, start the hoist motor 24. The hoist motor 24 drives the synchronous pulley set 23 to rotate. The synchronous pulley set 23 drives the hoist drum 21 to rotate through the connecting shaft 22, and winds the hoist drum 21, so as to lift the equipment to be repaired.
