Description

Nodular cast iron planet carrier supporting structure for wind power equipment Technical Field The utility model relates to the technical field of wind power equipment structural support, in particular to a spheroidal graphite cast iron planet carrier supporting structure for wind power equipment. Background The planet carrier supporting structure is a key component of a planetary gear transmission system in wind power equipment, is mainly used for supporting and fixing the position of a planetary gear, ensures the stability and reliability of the planetary gear in operation, has higher strength and rigidity to bear the influence of complex load in a wind power main transmission system, is manufactured through precision machining and heat treatment processes, is widely applied to wind power gearboxes, and has important effects on improving the operation efficiency and prolonging the service life of the whole wind power gearboxes. However, the existing planet carrier supporting structure generally has the problems of poor adjustment adaptability, complex operation, unstable positioning and the like, and is difficult to realize the height adjustment and stable installation of the supporting structure when facing gears with different thickness specifications or gear rotating shafts with different lengths, so that the assembly deviation or the operation instability of the gears are easily caused, and the overall performance and the service life of a transmission system are influenced. Therefore, a carrier support structure that can achieve high fine adjustment, convenient operation, and stable locking is needed to improve the versatility and reliability. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one purpose of the utility model is to provide the spheroidal graphite cast iron planet carrier supporting structure for the wind power equipment, which is suitable for mounting gears with different specifications by utilizing the height fine adjustment and stable locking of the adjusting plate, and is convenient to operate, stable and reliable. In order to achieve the above purpose, the spheroidal graphite cast iron planet carrier supporting structure for the wind power equipment comprises a top cover, wherein the bottom of the top cover is fixedly connected with a supporting frame, an adjusting plate is arranged in the supporting frame, gear mounting hole groups are formed in the supporting frame and the adjusting plate, a rod body is fixedly connected to the top of the adjusting plate, a plurality of limiting blocks are arranged on the outer wall of the rod body at equal intervals, a circular groove is formed in the top of the top cover, at least three arc grooves are distributed on the inner wall of the circular groove at equal intervals according to the circumference, two arc ribs are symmetrically arranged on the inner wall of each arc groove, the rod body penetrates through each arc groove, and the bottoms of the limiting blocks are attached to the tops of the arc ribs. Preferably, a circular groove is formed in the circular groove, at least three L-shaped inserting blocks are distributed at the bottom of the circular groove at equal intervals according to the circumference, the shape of each L-shaped inserting block is matched with that of the arc groove, and an end cover is connected with the inner wall of the circular groove in a threaded mode. Preferably, the gear mounting hole group comprises three first through holes which are arranged at the bottoms of the adjusting plate and the supporting frame at equal intervals according to the circumference, a second through hole is arranged at the center of the bottom of the supporting frame, and third through holes are arranged at the centers of the bottoms of the adjusting plate and the top cover.
