A kind of special-shaped type component lifting turning device
A kind of special-shaped type component lifting turning device, belongs to parts lifting tipping arrangement technical field.
At present, in large equipment manufacturing enterprise, most parts are changed between each process in processing, are to be added
Transhipment on work area to workbench, it can be related to lifting by crane turnover technology.Current parts hanging method mainly passes through steel wire
Rope tool fastens parts, hangs parts using overhead traveling crane and goes on processing platform, and the method is simple but safety coefficient is low, fits
It is easy to the parts of positioning for simple in construction, suspension centre, is not suitable for complicated, the big parts lifting of weight, workshop work
The life security of people is difficult to ensure.Meanwhile current parts hanging method is primarily directed to lifting and the suspension centre of parts
The control of position, and parts can be related in transhipment, the processing in work area to be added to workbench between each station during transhipment
To the change of the Working position of parts, the turn over function of suspender need to be considered, is not directed in hanging method.
Domestic and foreign countries mainly have two kinds for suspender lifting turnover technology method, and one kind is to do block with resilient key,
Hanger rod and elastic pin connection, resilient key is pressed down hanger rod and taken out, one kind is to do block with suspension ring, is blocked under the influence of center of gravity bad
With hanger rod decentraction, when snap ring and concentric hanger rod, hanger rod can be taken out.Though both the above method refers to the lifting upset of suspender,
But the drawbacks of serious all be present, it is impossible to widely use and complicated, it is not easy to remove, and low production efficiency, automaticity
It is not high, it is difficult to adapt to current production situation.
