Description
Technical field
The utility model relates to a kind of light-duty turntables, belong to special vehicle technical field.
Background technique
In engineering machinery, turntable is the important component with revolute function Work machine, is primarily due to: 1) realizing work
Make the revolution of device and the function of luffing；2) turntable is between cantilever crane and support frame of getting off, and plays what dress was got off with carrying
Connection function；3) in the operating condition, load is transmitted to turntable by cantilever crane, and turntable is being further transferred to support frame of getting off
On.In conclusion the intensity of turntable and rigidity largely affect the operation stability and reliability of equipment.
Traditional project machinery turntable is mostly that plane slab bending is welding manufacture in left and right after c-type side plate, and side plate cross section is
Quadrangle, for reduce rotation of rotary table when left side plate torsional deflection must will also between both side plate before and after side be welded to connect
Sealing plate, or even also need in the inclined top position welding reinforcement structure of both side plate, welding capacity is big, and consumptive material is more, manufacture complexity and weight
Greatly.
In addition, the wild effect of the generally existing operation shake of engineering machinery at present with revolute function, this very great Cheng
Degree is influenced by turntable rigidity is not strong.
Summary of the invention
In order to overcome the above-mentioned deficiency of the prior art, the utility model provides a kind of light-duty turntable, can not only mitigate knot
Structure weight, it is significant to the lightweight of vehicle, moreover it is possible to the mechanical property for improving turntable structure, for mitigating operation shake
Phenomenon also has great effect.
The utility model solve its technical problem the technical solution adopted is that: the turntable is using high-intensitive thin plate system
It makes, turntable includes outer panel, inside stiffening plate and bottom plate, and outer panel is integral type polygon, and front side and rear side are equipped with loss of weight
Slot, notch is symmetrical about face in turntable or so, upper and lower sides be it is open, be disposed with inside left and right sides inside stiffening plate, outside
Plate is integrally connected with bottom plate, and bottom plate is connect with rotation of rotary table device.
The utility model turntable structure form abandons the labyrinth form of conventional two-piece plane slab bending assembling welding, and
It is to be optimized for polygon integral structure form, traditional turntable side plate cross section is quadrangle, provided by the utility model light-duty
The outer panel section of turntable is polygon, better than quadrangle according to section rigidity theoretical judgment polygon rigidity.
Further improvement as the technical program designs, and is known by limiting principle, polygon chimb is then unlimited when infinitely more
Close to circle, and it may determine that circular cross-section rigidity is best, polygon shape in regular polygon according to section rigidity theory
Bending technique is complicated when making, therefore considers overall stiffness performance and anufacturability, and the integral type polygon turntable is using circle
Tubular structure, i.e. outer panel are cylindrical shape.In turn, specifically, the inside stiffening plate outer border and outer panel weld, outside
The bottom side outer border of side plate and bottom plate weld.
It further include one group of hinged axle sleeve as further improvement project, the inside which is welded on turntable upper end adds
Between strong plate and outer panel, hinged axle sleeve is connect by articulated shaft with cantilever crane.
It further include one group of luffing axle sleeve as further improvement project, which is welded on the inside in the middle part of turntable and adds
Between strong plate and outer panel, luffing axle sleeve is hinged by luffing axis and amplitude oil cylinder.
As scheme is still further improved, several connections are welded between the inside stiffening plate and outer panel of the turntable
Block.For connecting interior outer panel, realizes the transmitting of the power between both side plate, improve its mechanical property.
As further improvement project, reinforcement circle is additionally provided between the two sidewalls of the outer panel of the turntable lower end
Pipe.For improving the integral strength and rigidity of turntable.
Compared with prior art, a kind of light-duty turntable of the utility model changes turning for conventional planar slab bending form
Platform labyrinth simplifies structure type, improves rigidity property using polygon integral type outer panel, alleviates work
The phenomenon that industry is shaken, while using thin plate and making, it was both able to satisfy mechanical property demand, weight alleviates 50% again, is conducive to
Vehicle lightweight also makes its more low-carbon energy-saving environmental protection while promoting vehicle economy.
