Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wind power generation support equipment, and particularly relates to a universal clamping tool for a wind power gear box base. BACKGROUND

[0002] The test device of the wind power gear box adopts a back-to-back connection layout mode. During the test, an electric motor is used as a power source to drive an accompanying test gear box through a high-speed shaft coupling. The accompanying test gear box is connected with a low-speed end of a main test gear box through a drum gear coupling. Through loading on a generator end, the purpose of load test of the main test gear box is achieved. Since the maintenance cost of the wind power gear box is high, the on-tower maintenance technology is developed for the wind power gear box in consideration of the economy and rapidity of maintenance. At present, the on-tower maintenance of the wind power gear box basically corresponds to a set of opening tooling, the tooling has high procurement cost and small applicability. The tooling base connection adopts a through hole or a waist-shaped hole, the connection size is not adjustable or only can be adjusted in a single direction, and the adaptability is poor. When a new tooling is developed, a new tooling base needs to be purchased, the procurement cycle is long, the maintenance cycle is prolonged, the traditional tooling has small application range, the maintenance time is prolonged, and the power generation yield is reduced.

[0003] Therefore, the universal clamping tooling for the wind power gear box base is designed to solve the above problems. SUMMARY

[0004] To solve the problems raised in the background art, the present application provides a universal clamping tool for a wind power gear box base, which can be installed on the outside of a main test gear box and a test gear box by a supporting frame, and then an electric cylinder is started to push the fixed column down, and the fixed column in turn pushes the positioning frame down. Since the main test gear box and the test gear box are different in size, the clamping block can be pushed at the bottom of the positioning frame to slide along the opposite or same direction of the slot of the sliding groove one, so that the outer end of the clamping block can be inserted into the slot of the main test gear box and the test gear box, and then clamped and fixed. Then the electric cylinder is reversed to start, so that the clamping block and the positioning frame support the main test gear box and the test gear box and are lifted up, and then the subsequent adjustment of the limiting adjustment is facilitated. When the main test gear box and the test gear box are lifted up, the hydraulic cylinder on the support seat is started, and the output shaft of the two hydraulic cylinders on the opposite sides drives the guide rod to push the positioning seat to move to the opposite side. At this time, the bottom of the positioning seat is clamped in the sliding groove two, thereby enhancing the stability of the positioning seat during sliding. When moving to the calculation position, the two sides of the positioning seat are installed in the threaded holes of the supporting frame by large bolts, so as to realize the fixation of the supporting frame and the positioning seat. Then the electric cylinder is started again, and the electric cylinder places the main test gear box and the test gear box into the limiting slot on the top of the adjusting plate. At the same time, the adjusting plate compresses the compression spring one, and the compression spring one is compressed in the positioning seat. Due to the elastic property of the compression spring one, the adjusting plate continuously pushes against the main test gear box and the test gear box, and plays a certain buffering effect on the vibration of the main test gear box and the test gear box during operation. On the other hand, since the connecting part of the test gear box and the main test gear box is connected by a shaft coupling or a flange, the long-term load will cause serious wear at the connecting part. At this time, the limiting stopper is pulled out of the inside of the fixing sleeve, and then the outside of the limiting stopper is placed on the flange. Since the compression spring two is always in a stretched state, the limiting stopper can continuously resist the flange, thereby protecting the flange and preventing the flange from being damaged due to continuous vibration during operation.
