Overturning device for assembling hoist roller speed reducer assembly

Abstract

The invention discloses an overturning device for assembling hoist roller speed reducer assembly. The overturning device comprises a chassis truck composed of a truck frame, truck wheels and a guide wheel, wherein a left support and a right support are arranged on the upper part of the chassis truck; a power and driving device is arranged on the left support; a clamping device is arranged betweenthe left support and the right support; a power and driving device comprises a piston type pneumatic motor, a speed reducer and a driving gear; the clamping device comprises a driven gear which is fixed on the left support and engaged with the driving gear, a left fixture connected with the driven gear, a bearing frame which is coaxial with the left fixture and fixed on the right support and a screw which passes through the right support and the bearing frame and is matched with the central threaded hole of the bearing frame; a crank is fixed at the outer end of the screw; and the inner end of the crank is connected with a right fixture corresponding to the left fixture. The overturning device has the advantages of simple structure, stable performance, high assembly quality, high production efficiency, low cost and capability of realizing flexible overturn and positioning at any angle position and saving time and labor.

Description

technical field [0001] The invention relates to an overturning device, in particular to an overturning device used for assembly of a drum reducer assembly of a crane. Background technique [0002] At present, the assembly of the crane drum reducer assembly is mainly manual assembly, and the assembly process of the crane drum reducer assembly is relatively complicated, which not only requires high assembly quality, but also requires a large number of bolts to be tightened and distributed On both ends of the reel; if there is no suitable assembly tooling, it will be directly placed on the ground, which will bring a lot of inconvenience to the assembly: (1) The height of the reel is small, and the worker must bend over or squat down to work, and it is easy to get tired , affecting the assembly efficiency; (2) the quality of the reel and the reducer assembly built in it is large, it is difficult to manually turn over, and the labor intensity of the workers is high; (3) there are...
