Abstract
The utility model discloses a kind of swing arm extension type gin poles, are related to engineering machinery field.The crane is made of mast, flexible swing arm, hawser and its tensioning apparatus etc..Flexible swing arm includes two sections or the above slidable arm joint of two sections, and luffing is realized by hydraulic oil cylinder driving；Cable tensioning device applies corresponding tensile force according to swing arm pitch angle and hoisting weight to hawser.The crane of the utility model, light structure, operating flexibility, in addition to heavily loaded crane capacity, both horizontal operation amplitude had been expanded, also there is high-altitude jacking capacity simultaneously, the lifting radius for overcoming conventional gin pole is small, and the problem of operation adaptability difference is suitable for the job requirements such as lifting, carrying, working at height, emergency management and rescue.
Description
Technical field
The present invention relates to technical field of engineering machinery, are specifically related to a kind of gin pole.
Background technology
Gin pole is made of the gin pole of swing arm mast, swing arm, hoist engine etc., simple in structure, is one
The common lifting equipment of class.The making of its main member is simpler, and installation and dismounting are convenient, and hoisting weight is big, in use to peace
The place set is of less demanding, and place is adaptable, therefore is used widely in hoisting operation.
However this kind of crane disadvantage protrudes, since its boom length is fixed, luffing range is small, in horizontal amplitude and lifting
Height is restricted, and operation adaptability is poor, is simply possible to use in short distance big load lifting operation.
At the scene when operation, usually have heavy duty lifting, significantly horizontal feed, the several work demand such as elevate, such as answering
During first aid is helped, the article that faces a danger quickly is hung, extinguishing chemical elevates injection, personnel's requirements such as conveying in the air, generally requires to call
Distinct device is completed.Therefore, solve the problems, such as that jib crane job area is small, flexibility is poor, to expanding existing crane
Application range and ability have great importance.
Invention content
It is an object of the present invention to provide a kind of for having heavy load lifting, large radius operation and high-altitude and lifting operation function
Heavy-duty machine.
The technical solution adopted in the present invention is：
A kind of swing arm extension type gin pole, the device is by mast, flexible swing arm, hawser, cable tensioning device, oil
The compositions such as cylinder, it is characterised in that：Flexible swing arm includes two sections or the above slidable arm joint of two sections, is realized and is become by hydraulic oil cylinder driving
Width；One end of hawser is connected with its tensioning apparatus, and the other end is connected with the external part of flexible swing arm.
Further, a kind of swing arm extension type gin pole, it is characterised in that：Level according to the swing arm that stretches
Operation amplitude can design the multigroup hawser of installation.
Further, a kind of swing arm extension type gin pole, it is characterised in that；The crane of the present invention can be with
It, can also ground fixed installation as crane truck.
Further, a kind of swing arm extension type gin pole, it is characterised in that：The present invention is as vehicle-mounted lifting
When machine, mast is movable, is packed up in vehicle transport state, and when field operation erects and fixes.
Compared with prior art, its swing arm of gin pole of the invention uses telescopic, and luffing jib uses oil cylinder
Driving can expand horizontal operation amplitude, while also having high-altitude jacking capacity other than having heavily loaded crane capacity.Existing
Have in gin pole technology, there is not yet the method for the above technological invention, scheme or device.
Description of the drawings
Fig. 1 is the constructive embodiment of crane of the present invention.
Fig. 2 is multigroup wireline deployed embodiment of crane of the present invention.
Fig. 3 be crane of the present invention vehicle-mounted transport state under mast retraction embodiment.
In figure：Mast 1, flexible swing arm 2, hawser 3, cable tensioning device 4, oil cylinder 5.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.
Fig. 1 is the specific embodiment of crane structure of the present invention.The crane of the present invention is by mast 1, flexible swing arm 2, cable
The compositions such as rope 3, cable tensioning device 4, oil cylinder 5.Flexible swing arm 2 includes two sections or the above slidable arm joint of two sections, luffing
It is driven and is realized by oil cylinder 5；One end of hawser 3 fills 4 and set with the tensioning of its hawser to be connected, the external part of the other end and flexible swing arm 2
It is connected.
Fig. 2 is the specific embodiment of the multigroup wireline deployed of crane of the present invention.Horizontal operation amplitude according to the swing arm 2 that stretches
The multigroup hawser 3 of installation can be designed, one end of each group of hawser 3 fills 4 and set with the tensioning of its hawser to be connected, the other end and flexible swing arm 2
A joint arm section external part be connected.
Fig. 3 be crane of the present invention vehicle-mounted transport state under mast retraction embodiment.When vehicle-mounted transport, 1 He of mast
Flexible swing arm 2 withdraws and locks, and is transported with vehicle.
In low latitude when operation, 2 energy large radius of swing arm of stretching is stretched out, and expands job area, simultaneous retractable swing arm 2 also provides
Elevate operation function；Since mast 1 and hawser 3 provide skewed horizontal load power for the swing arm to overhang, flexible swing arm 2 is made to have more
Big bearing capacity, hoisting weight when increasing big horizontal operation amplitude.Flexible swing arm 2 realizes luffing by oil cylinder 5, with tradition
The hawser luffing mode of gin pole is compared, and luffing range is big, and luffing manipulates mobility strong, is adapted to when high-altitude lifts to making
The requirement of industry stationarity.
It should be appreciated that in the workshop of factory, goods yard and other fixed places, mode is fixedly mounted using ground, equally
The repertoire of vehicle-mounted mounting means may be implemented.
Specific examples are only used to explain the present invention described in above-mentioned, rather than limiting the invention.Without departing from the present invention
Basic principle in the case of, what those skilled in the art can be directed to that above-mentioned details make various apparent or equivalent repaiies
Change or replace, is all included in scope of the presently claimed invention.
