Description
One, technical field:
The present invention relates to a kind of construction machinery and equipment, specifically a kind of novel hydraulic crawler crane.
Two, background technology:
In the open air during construction operation, the hoisting crane preparation of construction that is absolutely necessary.Though rubber tired crane has maneuverability, capacity is big, and scope of work is big, compact conformation, job safety is reliable, and is easy to operate, good looking appearance, characteristics such as traveling comfort is good, but for the workyard away from hard surface, can not meet the demands, especially for requiring the lower wetland type area of grounding pressure, rubber tired crane is difficult to travel, and is less owing to the supporting leg area during work, the pressure that produces is very big, can't carry out construction operation.
Three, summary of the invention:
The purpose of this invention is to provide a kind of novel hydraulic crawler crane, it keeps the characteristics of rubber tired crane substantially, and can carry out operation in wetland type area, and grounding pressure is low, need not supporting leg and support, and operation is stable.
For achieving the above object, the technical scheme that the present invention takes is: be to improve on the basis of rubber tired crane, promptly include compositions such as caterpillar chassis, pivoting support, swing type mechanism, turntable, lifting mechanism, telescopic hoist boom, telescopic oil cylinder, amplitude oil cylinder, suspension hook, hydraulic efficiency gear, engine installation, counterweight assembly, operator's compartment.Turntable passes through swing type mechanism, pivoting support is installed on the caterpillar chassis, and can on caterpillar chassis, turn round, lifting mechanism, hydraulic efficiency gear, engine installation, the counterweight assembly, operator's compartment is installed on the turntable, the operating mechanism of hydraulic efficiency gear is arranged in the operator's compartment, one end of telescopic hoist boom is by bearing pin and turntable articulated lifting arm, lifting mechanism is arranged on suspension hook by its steel rope the other end of arm, telescopic oil cylinder is installed in the telescopic hoist boom, and it is flexible to drive telescopic hoist boom, one end of amplitude oil cylinder and turntable articulated lifting arm, the other end and telescopic hoist boom articulated lifting arm, swing type mechanism, amplitude oil cylinder, telescopic oil cylinder, lifting mechanism connects with hydraulic efficiency gear, and engine installation connects with the running gear of caterpillar chassis.
The hydraulic efficiency gear of operation power plant and drive thereof, running motor are realized walking of the present invention, and the operation hydraulic efficiency gear is realized operation by lifting mechanism, amplitude oil cylinder, telescopic oil cylinder, swing type mechanism, pivoting support etc.
Because the present invention changes the rubber-tyred chassis of rubber tired crane into caterpillar chassis, increased and ground-surface area of contact, reduced grounding pressure, can carry out operation in regions such as wetland, sandy grounds, also can save structures such as hydraulic ram supporting, and keep the characteristics of rubber tired crane.Therefore, the present invention has maneuverability, and scope of work is big, compact conformation, and job safety is reliable, and is easy to operate, good looking appearance, traveling comfort is good, and can carry out operation in wetland type area, and grounding pressure is low, and need not supporting leg and support, and characteristics such as operation is stable.
Four, description of drawings
Fig. 1 is a scheme drawing of the present invention;
Fig. 2 is the birds-eye view of Fig. 1.
Five, the specific embodiment
Accompanying drawing is embodiments of the invention, includes compositions such as caterpillar chassis 1, pivoting support 2, swing type mechanism 5, turntable 3, lifting mechanism 4, telescopic hoist boom 6, telescopic oil cylinder, amplitude oil cylinder 7, suspension hook 8, hydraulic efficiency gear 9, engine installation 10, counterweight assembly 11, operator's compartment 12.Turntable 3 is by swing type mechanism 5, pivoting support 2 is installed on the caterpillar chassis 1, and can on caterpillar chassis 1, turn round, lifting mechanism 4, hydraulic efficiency gear 9, engine installation 10, counterweight assembly 11, operator's compartment 12 is installed on the turntable 3, the operating mechanism of hydraulic efficiency gear 9 is arranged in the operator's compartment 12, one end of telescopic hoist boom 6 is by bearing pin and turntable 8 articulated lifting arms, lifting mechanism 4 is arranged on suspension hook 8 by its steel rope the other end of telescopic hoist boom 6, telescopic oil cylinder is installed in the telescopic hoist boom 6, and it is flexible to drive telescopic hoist boom (6), one end of amplitude oil cylinder 7 and turntable 3 articulated lifting arms, the other end and telescopic hoist boom 6 articulated lifting arms, swing type mechanism 5, amplitude oil cylinder 7, telescopic oil cylinder, lifting mechanism 4 connects with hydraulic efficiency gear 9, and engine installation 10 connects with the running gear of caterpillar chassis 1.
Telescopic hoist boom 6 general two joint arms or the three joint arms of adopting, present embodiment is three joint arms, to increase scope of work.
In order to increase stability better and to reduce grounding pressure, the caterpillar block of caterpillar chassis 1 can adopt high-intensity triangle caterpillar block, can increase the width between centers of both sides crawler belt, and chain rail assembly still adopts standard pitch.Like this, can satisfy the needs of different operating environments.
Caterpillar chassis 1 also can adopt the X rigid frame of widening as frame, with the raising torsional strength, and can increase stability.
The running gear of caterpillar chassis 1 can adopt by the hydraulic moving motor driven, drives the complete machine walking by drop-gear box; Drg is located in the built-in drop-gear box by the control of control oil; The hydraulic moving motor is driven by Variable plunger pump, energy automatic stepless speed-regulating, the control of big-flow high-pressure change-over valve; The both sides crawler belt can drive simultaneously, but also independent drive can realize pivot stud.
Therefore the present invention replaces former rubber-tyred chassis with caterpillar chassis, has increased and the contacting of ground Area has reduced grounding pressure, can carry out operation in regions such as wetland, sandy grounds, also can save hydraulic leg The structures such as supporting, and kept the characteristics of rubber tired crane. Therefore, the present invention has maneuverability, does The industry scope is big, compact conformation, and job safety is reliable, and is easy to operate, good looking appearance, comfortableness is good, and energy Carry out operation in the Wetland Type area, grounding pressure is low, and need not supporting leg and support, and the characteristics such as operation is stable.
