Description

Technical Field

[0001] This utility model relates to the field of water turbine installation technology, specifically a tooling center base for installing water turbines. Background Technology

[0002] A water turbine is a power machine that converts the energy of flowing water into rotational mechanical energy. It belongs to the category of projecting machinery in fluid machinery. Most water turbines are installed in hydropower stations to generate electricity. The installation and placement of water turbines in their designed locations is an engineering project. Different types and structural characteristics of water turbines require different installation procedures and methods, which are generally divided into installation positioning and embedded part installation. The installation process requires the use of corresponding tooling for positioning assistance.

[0003] For example, Chinese Patent CN118513764B discloses a support fixture for welding the turbine volute, which includes a base, a column rotatably mounted in the middle of the base, a rotating plate fixedly mounted on the top of the column, multiple slots evenly distributed on the rotating plate, and an arc-shaped slot equal in number to the slots. A drive assembly for driving the rotating plate to rotate is provided on the base, a connecting sleeve is fixedly mounted in the middle of the top of the rotating plate, a receiving pad is fixedly mounted on the top of the connecting sleeve, a fixing mechanism for installing the turbine volute is provided on the receiving pad, and a feeding mechanism is provided on one side of the base. This application provides a support fixture for welding the turbine volute, which enables intermittent rotation of the turbine volute, providing sufficient time for the feeding mechanism to deliver the blades to the welding position, thus improving the accuracy and efficiency of welding. The fixing mechanism prevents displacement caused by vibration or external force during welding, and the feeding mechanism realizes the transfer and cleaning of the blades. However, traditional center bases are mostly one-piece structures with a large overall volume, making them difficult to transport and install. Moving the center base to the installation position takes a lot of time. Therefore, this application proposes a center base fixture for installing a turbine to solve the above problems.
