Description
Technical field
The present invention relates to slewing crane fields, more specifically to a kind of sliding arm type rotary arm crane.
Background technique
Slewing crane is also referred to as rotating arm crane, is the middle-size and small-size hoisting equipment that developed recently gets up, and unique structure safely may be used
It leans on, has the features such as efficient, energy saving, time saving and energy saving, flexible, three-dimensional space obtains interior random operation, in field of the section away from the allocation and transportation of, intensive
It closes, more shows its superiority than other routinely handling appliances.
Slewing crane working strength be it is light-duty, crane is by column, swivelling arm device for revolving and driving and electric block group
At column lower end is fixed in concrete foundation by foundation bolt, drives spiral arm to turn round by cycloidal-pin wheel deceleration device, electricity
Dynamic cucurbit makees left and right linear running, and hoisting heavy on spiral arm I-steel.Radial arm of crane is hollow section structure, self weight
Gently, span is big, and lifting capacity is big, economy and durability.Built-in row rotating arm crane MODE Xing Zou mechanism, using the extraordinary work with rolling bearing
Engineering plastics walk wheel, and frictional force is small, walk brisk；Structure size is small, is particularly conducive to improve lift hook travel range.It is widely portable to factory
The weight handling of mine, the occasions of work and warehouse, harbour etc. above and below of the production line in workshop, assembly line and lathe.
In use, the slewing crane rate of wear is due to new engine parts machining, assembly and adjustment etc. fastly
The influence of factor, friction surface is coarse, and mating surface contact area is smaller, and the pressure-bearing situation on surface is uneven.Machine was being run
Cheng Zhong, the mutually chimeric friction of the concavo-convex portion of piece surface, grinds the metal fragment fallen, and as abrasive material, continue to participate in and rub
It wipes, more accelerates the abrasion of part matching surface.Therefore, the mill of components (especially matching surface) is be easy to cause in running-in period
Damage, the rate of wear are fast.At this moment, it if excess load operation, may cause the damage of components, generate initial failure.
The normal working range of pillar (rotary, revolving) crane (Y) is using column as the center of circle, and swivelling arm is the circle of radius, works as circle
When interior accessibility (S) stops swivelling arm rotation, without non-active area (N) in circle, when there are two barrier devices (S) in circle
When, the working range (Y) of such as Fig. 2, pillar (rotary, revolving) crane reduce, and non-active area (N) exists, and are more than the half of circle.
It is vertical when needing then to need to reinstall one when non-active area (N) uses pillar (rotary, revolving) crane, or by before
Pillar slewing crane is reinstalled, inconvenient, and pillar (rotary, revolving) crane factories and miness, workshop production line, assembly
In use, the often shadow by installation site other equipment in the occasions such as the upper and lower work of line and lathe and warehouse, harbour
It rings, pillar (rotary, revolving) crane needs to avoid the installation of these equipment, is inconvenient, influences performance.
Summary of the invention
