Description
Technical field
The present invention relates to slewing crane field, more specifically to a kind of sliding arm type rotary arm crane.
Background technology
Slewing crane is also referred to as rotating arm crane, is the middle-size and small-size hoisting equipment that developed recently gets up, unique structure, safely may be used
Lean on, possess efficiently, energy-conservation, it is time saving and energy saving, flexible the features such as, three-dimensional space obtains interior arbitrarily operation, in field of the section away from the allocation and transportation of, intensive
Close, its superiority is more shown than other routinely handling appliances.
Slewing crane working strength is light-duty, and crane is by column, swivelling arm device for revolving and driving and electric block group
Into 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, deadweight
Gently, span is big, and lifting capacity is big, economy and durability.Built-in row rotating arm crane MODE Xing Zou mechanisms, using the extraordinary work with rolling bearing
Engineering plastics walk wheel, and frictional force is small, and walking is brisk；Physical dimension is small, is particularly conducive to improve lift hook travel range.It is widely portable to factory
The weight handling of ore deposit, the production line in workshop, assembly line and the occasion such as the upper and lower work of lathe and warehouse, harbour.
In use, the slewing crane rate of wear is due to new engine parts machining, assembling and adjustment etc. soon
The influence of factor, its 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 jog of piece surface, grinds the metal fragment fallen, is used as abrasive material again, continues to participate in and rub
Wipe, more accelerate the abrasion of part matching surface.Therefore, the mill of parts (particularly matching surface) is easily caused in running-in period
Damage, the rate of wear are fast.At this moment, if excess load operation, the damage of parts may be caused, produce 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 that swivelling arm rotates, without non-active area (N) in circle, when two barrier devices (S) in circle being present
When, such as Fig. 2, the working range (Y) of pillar (rotary, revolving) crane reduces, and non-active area (N) is present, and more than the half of circle.
When needing use pillar (rotary, revolving) crane at non-active area (N), then need to reinstall one, or by standing before
Pillar slewing crane is reinstalled, inconvenient, and pillar (rotary, revolving) crane factories and miness, workshop production line, assembling
In use, often by the shadow of installation site other equipment in line and the occasion such as the upper and lower work of lathe and warehouse, harbour
Ring, pillar (rotary, revolving) crane needs to avoid the installation of these equipment, is inconvenient, influences performance.
