Problems solved by technology

[0002] The traditional method of overturning the lower frame of a medium-sized excavator is to use a sling to raise the lower frame to a certain height, let it become a vertical state, and then slowly lower the lower frame, so as to realize the lower frame from the horizontal In the vertical-vertical-horizontal state, this flipping method is very awkward and requires a wide field to realize, and only one sling is used to flip the lower frame weighing about 7.5T, which has serious safety hazards

Abstract

The invention provides a method for turning a lower frame of a medium size excavator, which is characterized by comprising the concrete steps of: respectively connecting a turnover traveling excavator to a first turnover machine and a second turnover machine, connecting the first turnover machine to one end of a first mechanical arm, and connecting the second turnover machine to one end of a second mechanical arm; respectively enabling the other ends of the first mechanical arm and the second arm to pass through the bottom of the lower frame to connect with the first turnover machine and the second turnover machine; operating the turnover traveling excavator to enable the lower frame to rise to a position with 1400+ / -100mm to the ground, and synchronously lifting the left sides of the first mechanical arm and the second mechanical arm and synchronously descending the right sides till the lower frame turns for 90 degrees; synchronously descending the right sides of the first mechanical arm and the second mechanical arm and synchronously lifting the left sides till the lower frame turns for 180 degrees; and operating the turnover traveling excavator to enable the lower frame to land on a flow line. The action of the invention has food flexibility and stability, and the whole set mechanical operation is simple and convenient.

Description

technical field [0001] The invention relates to a method for overturning the lower frame of a medium-sized excavator, which is used in overturning measures for structural parts assembly of construction machinery, and belongs to the technical field of overturning structural parts of excavators. Background technique [0002] The traditional method of overturning the lower frame of a medium-sized excavator is to use a sling to raise the lower frame to a certain height, let it become a vertical state, and then slowly lower the lower frame, so as to realize the lower frame from the horizontal In the vertical-vertical-horizontal state, this flipping method is very clumsy and requires a wide field to realize, and only one sling is used to flip the lower frame weighing about 7.5 tons, which has serious safety hazards. Contents of the invention [0003] The object of the present invention is to provide a novel turning method that can quickly, flexibly and stably realize turning ove...
