Description

Technical Field

[0001] The utility model relates to the technical field of energy storage unit hoisting, in particular to a vertical hoisting structure of an energy storage unit. Background Art

[0002] Existing large-scale pumped-storage hydropower plants generally use a vertical shaft arrangement, with the generator motor located above the pump-turbine, connected by a large shaft flange. The top cover, runner, and guide vanes, as key components of the pump-turbine, are all installed within the pump-turbine pit. To improve the unit's operational stability, large pumped-storage power stations require pump-turbine maintenance. This maintenance typically involves disassembly from above, first removing and hoisting the generator motor rotor, stator, and lower frame. The top cover is then disassembled into petals, and a bridge crane is used to hoist the top cover, guide vanes, and other components upwards one by one before maintenance can begin.

[0003] However, in the prior art, it is found that there are at least the following technical problems: the existing lifting structure cannot effectively fix the cylindrical components in the energy storage unit to facilitate its assembly and movement, and its practicality is not high.

[0025] The technical solution in the embodiments of the present application is to effectively solve the technical problem that the existing lifting structure cannot effectively fix the cylindrical components in the energy storage unit to facilitate its assembly and movement, and is not practical. The overall idea is as follows:

[0026] In response to the problems existing in the prior art, the utility model provides a vertical lifting structure of an energy storage unit, including a connecting chassis 1, a sleeve 101 is fixedly connected to the upper surface of the connecting chassis 1, a connecting top plate 102 is welded to the top of the sleeve 101, a clamping assembly 4 is provided inside the sleeve 101, a movable groove 104 is opened on the surface of the sleeve 101, and a hanging ring 103 is fixedly installed on the top of the connecting top plate 102.

[0027] In some embodiments, the clamping assembly 4 includes a hydraulic cylinder 41, which is fixedly installed inside the sleeve 101 and fixedly connected to the lower surface of the top plate 102. The movable end of the hydraulic cylinder 41 is fixedly connected to the moving block 42, and a plurality of connecting plates 46 are fixedly arranged on the upper surface of the connecting chassis 1. The middle part of the connecting plate 46 is fixedly installed with a rotating shaft 45, and the outer part of the rotating shaft 45 is rotatably connected to a bending splint 44. The lower ends of the bending splints 44 are respectively provided with anti-slip components 3, and the upper ends of the bending splints 44 pass through the movable groove 104 and are located at the upper end of the moving block 42, as shown in FIG. Figures 1 to 4 As shown, the hydraulic cylinder 41 is turned on so that its output end pushes the moving block 42 to move downward. At this time, the bending splint 44 is in an open state. Under the guidance of the crane, the bending splint 44 is located outside the object to be clamped. The hydraulic cylinder 41 is turned on, and the hydraulic cylinder 41 drives the moving block 42 to move upward. At this time, the bevel chamfer 43 above the moving block 42 contacts the bending splint 44. During the movement, the bending splint 44 rotates along the direction of the rotating shaft 45 under the action of the bevel chamfer 43 until the clamping sleeve 31 at the bottom end of the bending splint 44 is in close contact with the surface of the object, thereby completing the clamping of the object.

[0028] In some embodiments, the top of the moving block 42 is provided with an oblique chamfer 43, such as Figures 1 to 4 As shown, the chamfer 43 above the moving block 42 contacts the bending clamp 44 . During the movement, the bending clamp 44 rotates along the direction of the rotating shaft 45 under the action of the chamfer 43 .

[0029] In the specific implementation process, when the utility model is in use, it is first fixed to the hook below the crane through the hanging ring 103. Under the guidance of the crane, the device is placed just above the energy storage unit assembly. At this time, the hydraulic cylinder 41 is turned on so that its output end pushes the moving block 42 to move downward. At this time, the bending splint 44 is in an open state. Under the guidance of the crane, the bending splint 44 is located outside the object to be clamped, and the hydraulic cylinder 41 is turned on. The hydraulic cylinder 41 drives the moving block 42 to move upward. At this time, the oblique chamfer 43 above the moving block 42 contacts the bending splint 44. During the movement, the bending splint 44 is in an open state. Under the action of the angle 43, it rotates along the direction of the rotating shaft 45 until the clamping sleeve 31 at the bottom end of the bending clamping plate 44 is in close contact with the surface of the object, thereby completing the clamping of the object. At the same time, during the downward rotation of the bending clamping plate 44, the clamping sleeve 31 slides stably under the action of the guide rod 302 and compresses the return spring 301. Under the action of the return spring 301, the clamping sleeve 31 can be in close contact with the object, thereby improving the clamping effect. The anti-slip teeth 32 can prevent sliding during the clamping process. The connecting column 2 can strengthen the connection between the connecting top plate 102 and the sleeve 101 and the connecting bottom plate 1 to prevent accidents.
