The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1, Fig. 1 is the structural representation of hoisting crane one embodiment of the present invention.The embodiment of the present invention comprises:
The first car body 11 and the second car body 12.
The first car body 11 can be realized the combination of the first car body 11 and the second car body 12 and separate by being connected with dismounting each other with the second car body 12.
The first car body 11 comprises that hoist mechanism 110 and the first propulsion source 111, the first propulsions source 111 drive the first car body 11 to travel.
The second car body 102 comprises suspension 121, driving system 122, bearing bridge 123, drive axle 124 and the second propulsion source 120.
The second propulsion source 120 drives the second car body 12 to travel.This second propulsion source 120 can be combustion engine or electrical motor, and combustion engine can be spark ignition engine or diesel engine.Spark ignition engine is efficient, diesel energy-saving, and electrical motor environmental protection.Therefore, for the selection of the second propulsion source 120, depending on real needs, determine, do not make too many restrictions herein.
Wherein, bearing bridge 123 and drive axle 124 front and back arrange, and bearing bridge 123 and drive axle 124 all can turn to.Suspension 121 is arranged on bearing bridge 123 and drive axle 124.Driving system 122 is machine driven systems and is connected between the second propulsion source 120 and drive axle 124, for the transmission of power by the second propulsion source 120 to drive axle 124.Certainly, driving system 122 can be also power hydraulic system or pneumatic actuator system, and the selection of driving system 122, depending on real needs, does not make too many restrictions herein.
Preferably, suspension 121 is hydro pneumatic suspensions, and for the lifting of the vehicle body of controlling the second car body 12, the attitude of bodywork of capable of regulating the second car body 12, be convenient to the second car body 12 and successfully be connected with the first car body 11.Hydro pneumatic suspension refer to using the fluid transmission of pressure, with unreactable gas (being generally nitrogen) as elastic medium, the cutoff port of suspension oil cylinder inside, check valve etc. are as a kind of suspension of shock absorber component.The damping property that uses hydro pneumatic suspension to improve, and improve the load-bearing amount.
The second car body 12 further comprises controller 125 and controls the control cock group 1210 that suspension 121 carries out lifting.
Generally speaking, the first car body 11 is as the main body of hoisting crane, and the length of the second car body 12 is less than the length of the first car body 11.And the second car body 12 can be connected in the afterbody of the first car body 11 or separate from the afterbody dismounting of the first car body 11.
Concrete, the first car body 11 comprises that chassis 112, the second car bodies 12 can pass through connecting base plate 112, thereby realizes the second car body 12 is connected to the afterbody of the first car body 11.It should be noted that, the connection of the first car body 11 and the connection that being connected of the second car body 12 also comprises its controller and its control cock group, the first car body 11 comprises the control system (not shown), one mouth of this control system connects the input end of the controller 125 of the second car body 12, and another mouth of this control system connects the input end of the control cock group 1210 of the second car body 12.The first car body 11 is connected with the second car body 12, and the connection of controller and control cock group generally adopts docking mode, certainly also is not limited to this mode.Can be when the first car body 11 be connected with the second car body 12, the functions such as suspension 121 liftings of being controlled in the lump the travelling of the first car body 11 and the second car body 12, wheel steering, braking and being controlled the second car body 12 by the control system of the first car body 11, realize the integration of the second car body 12 and the first car body 11 steering swivel systems, brake system and suspension system.And, when the first car body 11 is connected with the second car body 12, the first car body 11 is the headstock as whole hoisting crane away from an end of the second car body 12.
Consult Fig. 2, Fig. 2 is the structural representation of the another kind of embodiment of hoisting crane of the present invention.When the second car body 12 is connected with the first car body 11, the center of gravity of the arm 13 of hoisting crane can move to the second car body 12 directions, the weight of by the first car body 11 and the second car body 12, jointly bearing arm 13.Can guarantee to wait to carry and travel the part distribution of weight to the second car body 12, thereby reduce each car body gross load, reduce the gross load of each axle.And, now, not needing to remove under the prerequisite of arm 13 and other overweight parts, hoisting crane can not need extras or counterweight vehicle to help hoisting crane transition in working space, thereby can greatly save the crane transition time, increases work efficiency.
Continue to consult Fig. 1, on the other hand, the second car body 12 can be from chassis 112 disassembles, thereby realizes separating of the second car body 12 and the first car body 11.And when the first car body 11 separates with the second car body 12, the headstock when headstock of the first car body 11 still is connection, the other end of the first car body 11 is its tailstock.Now, the end that the headstock of the second car body 12 is the first car body 11 second car body 12 contiguous first car bodies 11 while being connected with the second car body 12, the tailstock of the second car body 12 is the other end.
And, for make the second car body 12 with there is independent driveability after the first car body 11 separates, generally the second car body 12 is set to comprise the wheel that is no less than four, wherein, when wheel is four, two wheels coordinate installation with bearing bridge 123, and another two wheels coordinate installation with drive axle 124.But, if consider the increase load, can set up wheel, certainly, now need to consider set up bearing bridge or set up drive axle and match with the wheel that need to set up, be not described specifically herein.
The embodiment of the present invention, the first car body 11 is designed to have the first propulsion source 111, the second car body 12 is designed to have the second propulsion source 120, and the second car body 12 can be connected and be dismantled with the first car body 11, when the second car body 12 is connected with the first car body 11, can integrate its propulsion source and control system, can increase the driving dynamics of hoisting crane, especially can improve the hill climbing ability of hoisting crane.And, when the second car body 12 is separated from the first car body dismounting, the second car body 12 has from travelling ability, can carry out the adjustment of body gesture, and conveniently with hoisting crane, is connected.
Consult Fig. 3, Fig. 3 is the structural representation of the additional axle device embodiment of hoisting crane of the present invention.The embodiment of the present invention comprises:
Wherein, bearing bridge 223 and drive axle 224 all can turn to, and bearing bridge 223 and drive axle 224 front and back arrange, suspension 221 is arranged on bearing bridge 223 and drive axle 224, driving system 222 is connected between propulsion source 220 and drive axle 224, for the transmission of power by propulsion source 220 to drive axle 224.Suspension 221 is hydro pneumatic suspension, the damping property that uses hydro pneumatic suspension to improve, and improve the load-bearing amount.
Certainly, additional axle device will have the ability that can independently travel, and additional axle device is designed to comprise control cock group 2210, controller 225 and stop mechanism (not shown).Control cock group 2210 is controlled suspension 221 liftings, the stop mechanism setting also is connected in drive axle 224, controller 225 connects respectively propulsion source 220, drive axle 224 and stop mechanism, controls respectively power, the braking of stop mechanism and the turning to of drive axle 224 of propulsion source 220.
And the quantity of drive axle can be two or more.Can coordinate the raising that arranges of wheel to be somebody's turn to do additional axle device load-bearing amount.
