Gear box overturning auxiliary tool and gear box overturning method

Abstract

The invention discloses a gearbox overturning auxiliary tool and a gearbox overturning method.The gearbox overturning auxiliary tool comprises a torque arm support, a fixed base and an adjustable supporting base, the torque arm support comprises a hanging ring, a main support, a rotating bolt, a supporting pad and a cylindrical shaft, the hanging ring is installed at one end of the main support, and the rotating bolt is installed at the other end of the main support; the other end of the main support is of a frame structure with an opening in one side, the frame structure is composed of four side plates and a closed cover plate fixed to the four side plates, a rotating bolt is screwed into each side plate, a supporting pad is fixed to the bottom end of each rotating bolt, a cylindrical shaft is fixed to the closed cover plate, and the cylindrical shaft is fixed to the bottom end of each rotating bolt. And a V-shaped birdmouth matched with the cylindrical shaft is formed in the upper part of the fixed base. The gear box overturning device can overturn the gear box by utilizing the gravity of the gear box through matching of a travelling crane, is simple in structure, easy and convenient to operate, high in safety coefficient and low in manufacturing and production cost, and can be used in batch production.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission equipment, and more particularly relates to a gear box turning auxiliary tool and a gear box turning method implemented by using the gear box turning auxiliary tool. Background technique [0002] In the assembly process of large gearboxes, vertical assembly and horizontal installation are often used, which requires the gearbox to be turned over after the vertical assembly is completed, and the gearbox is placed in a horizontal position. The following two flipping methods are generally used in the prior art: [0003] The first flip method, such as figure 1 As shown in the figure, the gearbox 300 is turned over by a special turning machine 100, the mechanical arm of the turning machine 100 clamps the torque arm of the gearbox 300, and the mechanical arm is driven by electrical and hydraulic means to drive the gearbox to move, so as to realize the operation of the gearbox 300. flip....

AI Technical Summary

Problems solved by technology

Due to the complex structure and expensive price of the turning machine itself, the use and cost of this turning method are relatively high;

[0004] The second flipping method, such as figure 2 As shown, the gear box 300 is turned over by a crane or a crane 200, and the gear box 300 is turned over by the hoisting and lowering of the main hook and the auxiliary hook by the crane or the crane 200. Moreover, it takes a long time to turn over due to manual operation, so it is not suitable for mass production.
