A kind of improved muck haulage vehicle Der Kofferraumdeckel
Technical field
Present invention is mainly used for the uses of building engineering field muck haulage vehicle Der Kofferraumdeckel.
Background technology
Current muck haulage vehicle Der Kofferraumdeckel only locally covers compartment, and the dust in compartment is still in pollution environment.
Invention content
The present invention overcomes drawbacks described above, it can completely cover the compartment of muck haulage vehicle, reduce the pollution to environment;It
Mainly by hydraulic system(1), stand(3), supporting rack(5), tripod(6), axis A(7), mandril(8), Der Kofferraumdeckel(9)Composition;Liquid
Pressure system(1)Hydraulic cylinder and supporting rack(5)Left end fix, supporting rack(5)Right end be fixed on stand(3)On, hydraulic pressure
System(1)Piston nose be fixed with bulb(12), stand(3)Lower end and vehicle frame(11)It is fixed, stand(3)Upper end fix
There is axis A(7), tripod(6)One end and axis A(7)It is hinged, i.e. tripod(6)One end can be around axis A(7)Rotation, tripod
(6)The other end and Der Kofferraumdeckel(9)It is fixed, Der Kofferraumdeckel(9)And tripod(6)It can be around axis A(7)Rotation, mandril(8)Right end
With axis A(7)It is hinged, mandril(8)It can be around axis A(7)Rotation, mandril(8)Left end and Der Kofferraumdeckel(9)It is fixed, mandril(8)Under
There is top nest in portion(13), bulb(12)Appearance and size with top nest(13)Size be mutually matched, bulb(12)It can be in top nest
(13)Interior sliding, compartment(10)Upper end be fixed with elongated compartment board top(15), compartment(10)Upper right side be fixed with bearing
(2), bearing(2)Idler wheel is installed(14), Der Kofferraumdeckel(9)Lower end be fixed with elongated race(4), compartment board top(15)And rolling
Wheel(14)Appearance and size and race(4)Appearance and size be mutually matched;The present invention main operational principle be:Muck haulage vehicle dress soil
Fang Shi is mounted on and drives indoor hydraulic system(1)Control switch start, hydraulic system(1)Piston rise, the ball of piston
Head(12)In mandril(8)The top nest of lower part(13)Inner edge top margin slides, by Der Kofferraumdeckel(9)It jacks up upwards, Der Kofferraumdeckel(9)Around axis A
(7)An angle is rotated, by Der Kofferraumdeckel(9)It opens;After the earthwork loads, bounce back hydraulic system(1)Piston, Der Kofferraumdeckel
(9)It closes;When muck haulage vehicle unloads soil, in the case where the piston top for unloading native hydraulic system is lifted, compartment(10)One angle of counterclockwise, together
When compartment(10)On idler wheel(14)Along Der Kofferraumdeckel(9)Race(4)It rolls, drives Der Kofferraumdeckel(9)Around axis A(7)Clockwise
An angle is rotated, by Der Kofferraumdeckel(9)It opens;After unloading soil, the piston retraction of native hydraulic system is unloaded, by compartment(10)It is multiple
Position, while driving compartment(10)On idler wheel(14)Along Der Kofferraumdeckel(9)Race(4)Backscrolling, by Der Kofferraumdeckel(9)It closes
It closes;It needs to illustrate:Push up nest(13)Length be equal to hydraulic system(1)Pistons work when maximum extension elongation, hydraulic system(1)
Piston retraction reset be Der Kofferraumdeckel(9)When closing, bulb(12)Just it is in top nest(13)Right end.

Specific implementation mode
The specific implementation mode of the present invention has been described in detail in invention content, is not repeated herein, needs to illustrate:Hydraulic pressure system
Der Kofferraumdeckel 9 only after muck haulage vehicle fills soil and dress soil, is opened and is closed, other situations do not work by system 1.
