Automatic field grinding device for water turbine

Abstract

The invention provides an automatic filed grinding device for a water turbine. The automatic filed grinding device comprises an annular track trolley system, a vertical lifting system, a horizontal linear motion system and a grinding robot; the annular track trolley system involves an annular track and an RGV arranged on the annular track, the annular track is arranged around a runner hub, and theRGV can move in the circumferential direction of the annular track; the vertical lifting system is arranged on the RGV and is a vertical lifting platform, the horizontal linear motion system is arranged at the upper portion of the vertical lifting platform, and the grinding robot is arranged on the horizontal linear motion system; and the vertical lifting platform is used for driving the horizontal linear motion system to ascend and descend, and the horizontal linear motion system is used for driving the grinding robot to move horizontally so that the grinding robot can move to a position needing to be ground. The automatic filed grinding device for the water turbine has the beneficial effects that the grinding robot can be conveyed to any position, needing to be ground, of the inner wallof a runner chamber or blades of the runner hub, the automatic grinding function is achieved, and the automatic filed grinding device has the advantages of being good in rigidity, convenient to operate and high in grinding precision and efficiency.

Description

technical field [0001] The invention relates to the technical field of hydraulic turbine maintenance equipment, in particular to an on-site automatic grinding device for hydraulic turbines. Background technique [0002] During the maintenance process of the water turbine, it is necessary to grind the inner wall of the water turbine runner and the lower part of the blade of the runner body. The on-site grinding operation is generally done manually. The manual grinding operation is intensive and inefficient, and the accuracy of manual grinding cannot be guaranteed; , the on-site grinding environment is harsh, the interior of the turbine is a closed structure, the grinding area has a large diameter (about 10 meters) and a high height (about 5 meters), the light is not good, and the dust generated by grinding is serious, which is very harmful to the health of the grinding personnel. Therefore, it is necessary to develop an automatic grinding device for water turbines to replace ...
