It is difficult to meet the high-speed overload job requirements of increasingly stringent.
(3) summary of the invention:
To this end, the present invention proposes a kind of closed chain formula combination drive front-handling mobile crane, its object is to
Make the standby bigger power output of crane tool and higher reliability, and make complete machine cost the cheapest, dimension
Protect cost of upkeep lower.
It is capable of the closed chain formula combination drive front-handling mobile crane of above-mentioned purpose, sets including based on vehicle frame
Large arm, large arm elevating mechanism and the large arm swing mechanism put, except that described large arm includes pitch arm
And swing arm, the lower end of described pitch arm is hinged in vehicle frame rear portion, and the rear end of described swing arm is hinged in bows
Facing upward arm upper end, the front end of swing arm arranges clamping device；Described large arm elevating mechanism is located at large arm front,
Being included in lifting fork and lifting linking member that large arm lateral symmetry is arranged, the lower end of described lifting fork is in car
The anterior hinge of frame, the upper end of described lifting linking member is hinged with the arm body of swing arm, the upper end of lifting fork
It is hinged with the lower end of lifting linking member；Described large arm swing mechanism is located in the middle part of large arm, is included in large arm both sides
Symmetrically arranged swing arm and swing connecting bar, the lower end of described swing arm is hinged in the middle part of vehicle frame, described
The front end of swing connecting bar forms compound hinges, pendulum with the hinge point of lifting linking member lower end and lifting fork upper end
The upper end of lever and the rear end of swing connecting bar are hinged；The common drive mechanism of described lifting fork is for being located at car
High-power conventional motor on frame, the common drive mechanism of described swing arm is the small-power being located on vehicle frame
Servomotor, or the common drive mechanism of described lifting fork is the small-power servomotor being located on vehicle frame,
The common drive mechanism of described swing arm is the high-power conventional motor being located on vehicle frame.
In said structure, the lifting that described large arm elevating mechanism and large arm swing mechanism are controlled by motor is put
Bar and the swing of swing arm and realize the position adjustments of clamping device, both resultant motions realize clamping dress
Put the handling to container.
Beneficial effects of the present invention:
1, closed chain formula combination drive front-handling mobile crane of the present invention uses high-power conventional motor and small-power
The strategy of servomotor combination drive, compared with pure servomotor or hydraulically powered mode, has more
Big power output and higher reliability, and complete machine cost is the cheapest, and maintaining cost is lower.
2, the present invention is directly driven by a motor, linkage transmission realizes handling, lifting task, can be effective
Conventional hydraulic formula face-up transporting hoist of container crane process and assemble is overcome to require high, life-span not length, leakage of oil etc.
Shortcoming.
3, overall structure of the present invention is that outer revolute pair drives, closes chaindriven form, and all motors are respectively mounted
On vehicle frame, effectively reduce the weight of each component, have that movement inertia is little, track output is flexible, smart
Degree advantages of higher.
