Embodiment 1

[0032] As shown in the accompanying drawings, an auxiliary working tool 1 for quickly screwing the double-ended studs of the gearbox of a wind power generation unit into the base body. A ratchet wrench 2 is installed on the auxiliary working tool 1. The lower part of the working tool 1; the auxiliary working tool 1 is driven by rotating the ratchet wrench 2, and then the double-ended stud 3 is quickly screwed into the gearbox base of the wind power generating set. The auxiliary operation tool 1 includes a pre-embedded sleeve 6, which is a sleeve with a through hole in the center; one end of the pre-embedded sleeve 6 is provided with an internal thread 5 matched with a double-ended stud. The middle part of the embedded sleeve 6 is provided with a ball head internal thread 7 for installing the sleeve ball head, and the sleeve ball head 4 is installed in the ball head internal thread 7; the other end of the embedded sleeve 6 is provided with a ratchet wrench Square counterbore 8,...

Abstract

The invention discloses a method and tool for screwing a wind turbine generator system gear case stud in a base body rapidly. The method for screwing the wind turbine generator system gear case stud in the base body rapidly is characterized in that a ratchet wrench and an operation auxiliary tool are adopted for combined operation and the stud is rapidly screwed in the wind turbine generator system gear case base body. According to the combined operation of the ratchet wrench and the operation auxiliary tool, the operation auxiliary tool is sleeved with the ratchet wrench, the wind turbine generator system gear case stud is sleeved with the operation auxiliary tool, the ratchet wrench is rotated so that the operation auxiliary tool can be driven to rotate, the stud can be driven to rotate synchronously through the operation auxiliary tool, and therefore the stud can be screwed in the base body rapidly.

Description

technical field [0001] The invention relates to an installation method and auxiliary operation tool for a wind turbine generating set, in particular to a method and a tool for quickly screwing a double-ended stud of a gearbox of a wind-driven generating set into a base body, and is mainly suitable for double-ended studs of a gearbox of a wind-driven generating set with large blades. The installation of the column can also be used for the fixing of other stud bolts. Background technique [0002] The mounting bolts of the gearbox of the large-blade wind turbine are studs, and the studs must be pre-screwed into the main frame during the assembly of the gearbox. Since the double-ended stud has no clamping part, it cannot be pre-embedded with an open-ended wrench or a socket. At present, the main frame is screwed into the main frame by hand, which is slow and inefficient. However, since both ends of the double-ended stud are threaded, there is no clamping part, and the hand is ...
