Description

Technical Field

[0001] This utility model relates to a tool for installing locking pins on turbine blades of a generator unit, belonging to the technical field of heavy-duty gas turbine equipment. Background Technology

[0002] Locking pins (or locking pins) are a critical component in heavy-duty gas turbines (such as the GE9F) to ensure blade stability during operation and prevent displacement due to vibration or airflow impact. Specifically, locking pins are typically used to secure and lock the turbine blades in place to ensure they do not accidentally loosen or fall off during operation.

[0003] When installing new moving blades, it is extremely important to ensure that each blade is correctly aligned and securely fixed. If the blades cannot be correctly positioned during manual installation, the locking pins cannot be installed properly, which may lead to unstable equipment operation, reduced efficiency, or even serious safety hazards.

[0004] To facilitate the installation of new moving blades and ensure the smooth installation of locking pins, a specialized installation tool can be designed. This tool will help workers align and secure the blades more easily, while ensuring operational safety and convenience, reducing worker workload, and improving installation accuracy. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a tool for installing locking pins on turbine blades, thereby solving the aforementioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a turbine blade locking pin installation tool, comprising an installation tool; the installation tool includes a tool body and a side vertical end; a limiting pressure block is connected to one side of the side vertical end; the limiting pressure block is horizontally arranged with the tool body; a rotating shaft is connected to the tool body; an eccentric pressure block is connected to one side of the rotating shaft, and a rotating handle is connected to the other side shaft end.

[0007] Furthermore, the eccentric pressure block is positioned on the same side as the limiting pressure block, and the center point of the eccentric pressure block is not at the center of the rotation axis.

[0008] Furthermore, the rotating shaft is connected to the tool body via a bearing component.

[0009] The beneficial effects of this utility model are: by using the above-mentioned tools for installation, it is possible to safely and conveniently install new moving blade locking wires and locking pins during the maintenance of gas turbines, thereby improving safety and work efficiency.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0014] like Figure 1 As shown, a turbine blade locking pin installation tool for a generator set includes an installation tool; the installation tool includes a tool body 1 and a side vertical end 2; a limiting pressure block 3 is connected to one side of the side vertical end 2; the limiting pressure block 3 is arranged horizontally with the tool body 1; a rotating shaft 11 is connected to the tool body 1; an eccentric pressure block 4 is connected to one side of the rotating shaft 11, and a rotating handle 5 is connected to the other side of the shaft end.

[0015] In this preferred embodiment, the eccentric pressure block 4 is positioned on the same side as the limiting pressure block 3, and the center point of the eccentric pressure block 4 is not at the center of the rotation axis.

[0016] In this preferred embodiment, the rotating shaft 11 is connected to the tool body 1 via a bearing component.

[0017] Working principle: During use, wait for the locking wire to be placed in place, then place the limiting block 3 inside the locking wire groove, and then release the eccentric block. Until the limiting block 3 is placed in the appropriate position in the groove, operate the rotating handle 5 to drive the eccentric block 4 to rotate, squeezing the locking wire and installing it in place.

[0018] After on-site trials, it was confirmed that the locking wire and locking pin of the new moving blade can be installed much more conveniently, improving the work efficiency of on-site personnel; avoiding manual installation by personnel, greatly improving the safety of personnel during operation, which is of great significance to on-site work safety; at the same time, it avoids damage to the moving blade caused by improper operation, which has great economic significance; and it also provides convenience for the installation work, reduces the inconvenience of on-site operation, and greatly saves working time and safety costs.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
