Description

Technical Field

[0001] This utility model relates to the field of turbine runner turning technology, specifically a turbine runner turning device for an axial-flow propeller-type water turbine. Background Technology

[0002] The runner of an axial-flow propeller turbine is a large, complex, precise, and very heavy cast steel component, usually spherical or ellipsoidal in shape. After long-term operation, the runner and blades need to be periodically lifted out of the turbine pit for inspection, flaw detection, repair, or replacement. The runner contains a complex blade operating mechanism. In the vertical position, these components are located deep inside the runner, making the maintenance space extremely small and poorly lit, making it difficult for personnel to enter or perform effective operations. When flipped to a horizontal position, the runner can be placed stably, and its internal structure becomes more accessible, allowing maintenance personnel to safely and conveniently enter the interior or conduct inspection and maintenance work from all directions.

[0003] For example, the announcement number CN205772771U is named the Axial Flow Propeller Turbine Runner Turning Structure. This device includes an axial flow propeller turbine runner, a first lifting device, a second lifting device, and a third lifting device. The first lifting device, the second lifting device, and the third lifting device are fixed to the axial flow propeller turbine runner to ensure that the wire rope is still under good stress when it is in abnormal contact with the lifting device, and to prevent harmful wear and cuts.

[0004] The aforementioned device is equipped with multiple lifting points and lifting devices to turn the wheel over. However, the suspension method can easily lead to rope breakage, and the wheel is prone to damage and collapse without suspension traction. Utility Model Content

[0005] The purpose of this invention is to provide a device for turning over the runner of an axial-flow propeller turbine, in order to solve the problem mentioned in the background art that the suspension method is prone to rope breakage, and the runner is prone to damage and collapse without suspension traction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an axial-flow propeller turbine runner turning device, comprising a runner body and a first fixing frame;

[0007] Also includes:

[0008] A first fixed seat is installed on one side of the upper end of the rotating wheel body.

A slide rod is connected below the first support assembly, and the slide rod is flush with the screw. First fixing frames are symmetrically arranged at both ends of the slide rod, and the first fixing frames are flush with the second fixing frames.

[0011] Preferably, both the first support assembly and the second support assembly consist of a sliding block, a connecting seat, and a support rod. The two sets of sliding blocks are connected to the corresponding sliding rod and screw through threaded holes or round holes on their surfaces. The connecting seat is located at the upper end of the sliding block. One end of the support rod is hinged to the connecting rod, and the other end of the support rod is hinged to the connecting seat.

[0012] Preferably, a second fixed seat is provided on the other side of the upper end of the wheel body, and a steel cable is connected to the upper end of the second fixed seat, and the steel cable is sleeved in the inner hole of the second fixed seat.

[0013] Preferably, a bearing is installed in the inner hole of the second fixing seat, and the steel cable is sleeved inside the bearing.

When the rotating wheel body needs to be turned over, the screw is driven to rotate by the motor, which drives the support components to move to one side, thus causing the rotating wheel body to tilt. The first support component and the second support component can support the rotating wheel body during the movement, preventing it from slipping during the turning process.

[0020] (2) By installing a support frame at the bottom of the wheel body and hinged between the support frame and the wheel body, the wheel body can be turned over and rotated along the axis between the support frame and the rotating seat, which further improves stability. At the same time, a second fixed seat is set on the other side of the upper end of the wheel body. The crane and hoist components are connected to the second fixed seat through steel cables. The traction and suspension of the steel cables are used to assist the turning of the wheel body. Attached Figure Description
