Description
Technical field
The present invention relates to crane technical field, is specifically a kind of Crane Jib Structure.
Background technology
With the intensified competition in crane hanging component market, super-tonnage crane is straight in general lifting marketing profit
Line glides, and the main profit field of country's super-tonnage crane lifting work at present concentrates on wind-powered electricity generation installation and maintenance market.Wind
Electric installation and maintenance market is no longer a wide range of, significantly field overall performance advantage for the demand of crane, but is concentrated
The requirement of lift heavy amount when larger for lifting altitude, and more focus on convenience, the economy of transition and dismounting.
For at present, a Fans are after installation is complete, during crane transition, because crane is from great, brachium length, vehicle
Center of gravity is uneven, it is necessary to variable-amplitude auxiliary arm combination in front is dismantled, and is re-assemblied again to next Fans lifting scene, during also
Need to dismount suspension hook, connect steel wire rope and lift arm, whole disassembly process need 4 to 5 it is small when, undoubtedly consume time and people
Power, while detaching structure needs to aid in vehicle to be transported, and adds transition cost.
The content of the invention
In order to improve the convenience that dismounting uses, transition cost is reduced, the present invention provides a kind of component when reducing transition
Quantity is dismounted, easy to the Crane Jib Structure for assembling and transporting.
The present invention is achieved through the following technical solutions：A kind of Crane Jib Structure, including car body and after being hinged on car body
The flexible principal arm of side；Amplitude oil cylinder I is hinged between the leading flank and car body of the flexible principal arm lower part first segment；Flexible principal arm
The leading flank of lower part first segment is also hinged with setting-up, and setting-up luffing oil is hinged between setting-up and flexible principal arm lower part first segment
Cylinder II；The flexible principal arm upper end is hinged with tower arm；Tower arm stent is hinged with front side of the tower arm, the tower arm stent with
Tilting-preventing rod is connected between tower arm；Elevator is installed in the setting-up；Variable-amplitude steel wire rope is connected with the car body；The change
After the width steel wire rope other end bypasses setting-up outer end, tower arm stent outer end successively, it is connected on elevator.
Preferably：The setting-up amplitude oil cylinder II is located at the upside of amplitude oil cylinder I.
Preferably：The tower arm stent outer end is connected with hanging wheel；The variable-amplitude steel wire rope is wound on hanging for tower arm stent outer end
On wheel.
Preferably：Described tilting-preventing rod one end is detachably connected with tower arm stent, and the tilting-preventing rod other end is hinged with tower arm.
Compared with prior art, the beneficial effects of the invention are as follows：Folding jib structure, eliminates during transition
Dismounting variable-amplitude auxiliary arm, the variable-amplitude auxiliary arm that rises and falls, dismount suspension hook, connect steel wire rope and assistant conveyance vehicle, greatly reduces transition
Cost, improves transition efficiency.

Embodiment
It is the specific embodiment of the present invention below, in conjunction with attached drawing, the present invention will be further described.
With reference to shown in Fig. 1, a kind of Crane Jib Structure, including car body 1 and the flexible principal arm 2 for being hinged on the rear side of car body 1；
Amplitude oil cylinder I 3 is hinged between the leading flank and car body 1 of 2 lower part first segment of flexible principal arm, is stretched by amplitude oil cylinder I 3 to control
The rotation and positioning of contracting principal arm 2.Setting-up 5 is also hinged with the leading flank of flexible 2 lower part first segment of principal arm, in setting-up 5 with stretching
Setting-up amplitude oil cylinder II 6 is hinged between 2 lower part first segment of principal arm, come the rotation of setting-up 5 and is determined by setting-up amplitude oil cylinder II 6
Position.Flexible 2 upper end of principal arm is hinged with tower arm 4；The front side of tower arm 4 is hinged with tower arm stent 7, tower arm stent 7 and setting-up phase about 5
It is right.Tilting-preventing rod 8 is connected between tower arm stent 7 and tower arm 4；Tower arm 4 is held in the end of tower arm stent 7 by steel wire rope,
Coordinate tilting-preventing rod 8 again to realize the support of tower arm 4 and positioning；8 one end of tilting-preventing rod is detachably connected with tower arm stent 7, is prevented
8 other end of hypsokinesis bar is hinged with tower arm 4, facilitates the dismounting of tower arm 4.Elevator 9, the connection of 7 outer end of tower arm stent are installed in setting-up 5
There is hanging wheel 7-1；10 one end of variable-amplitude steel wire rope is connected on car body 1, and 10 other end of width steel wire rope is successively around 5 outer end of setting-up, tower
After the hanging wheel 7-1 of 7 outer end of arm support, it is connected on elevator 9.
The course of work：
As shown in Figure 1, it is job state schematic diagram of the present invention；
As shown in Fig. 2, when starting to remove, flexible principal arm is slowly retracted, while elevator packs up variable-amplitude steel wire rope, keeps tower arm stent
It is parallel with setting-up, maintain the stabilization of tower arm；Until flexible principal arm is full reduced；
As shown in figure 3, elevator slowly loosens variable-amplitude steel wire rope, tower arm slowly tilts, and falls；Remove one end of tilting-preventing rod 8；
As shown in figure 4, setting-up amplitude oil cylinder II is retracted, setting-up is transferred；
As shown in figure 5, amplitude oil cylinder I is retracted, flexible principal arm is placed on car body, flexible principal arm lie prone it is flat, in transition state；
The installation process of the present invention is opposite with above-mentioned demolishing process.
