Description
Technical field
The present invention relates to a kind of setting-up balance weight mounting auxiliary, belongs to engineering machinery field, and specifically a kind of crawler belt rises
Heavy-duty machine setting-up balance weight dismounts luffing device certainly.
Background technology
Balance weight has application in numerous engineering machinery, primarily to meeting the performance of car body and keeping the steady of vehicle
It is qualitative.By taking crawler crane as an example, in order to improve transaction capabilities, generally moveable balance weight-super is configured to crawler crane
Balance weight is played, the lifting performance of vehicle is improved by changing the amplitude of setting-up balance weight.
Super lifting working condition erection sequence, arm-tie between installation mast, setting-up mast and setting-up mast and mast, by setting-up balance weight
Suspension arm-tie is connected with setting-up mast top arm head, tightens up main variable-amplitude steel wire rope and setting-up mast is pulled up into certain angle；Peace
Principal arm system is filled, principal arm system is connected with setting-up mast with setting-up changing-breadth system, tightens up main transformer width system ropes simultaneously
Setting-up variable-amplitude steel wire rope is released, pull-up mast to operating angle, setting-up derricking device for counterweight one end is connected separately with main frame
One end is connected with setting-up balance weight suspension arm-tie, and finally setting-up balance weight suspension arm-tie lower end is connected with setting-up balance weight
Connect, super lifting working condition assembling since then finishes.
, it is necessary to setting-up changing-breadth system is disconnected when super lifting working condition changes brachium or changes operating mode, now setting-up mast rear portion
Whole system can not self-balancing, it is necessary to setting-up balance weight suspension arm-tie be disconnected, setting-up mast has to turn back, now vehicle master
Arm system, setting-up mast and mast separate with setting-up balance weight changing-breadth system, if now complete machine want displacement must use it is auxiliary
Crane is helped to sling setting-up balance weight below and setting-up derricking device for counterweight, being at liftoff state can shift；Move
It is related to two car coordination problems during position, complex operation, efficiency is low；Meanwhile at this stage, setting-up derricking device for counterweight,
When setting-up balance weight suspension arm-tie is connected with setting-up balance weight three, because setting-up mast has certain angle when turning back
There is certain error position when error or setting-up balance weight are placed, and causes setting-up balance weight suspension arm-tie to be re-mounted with setting-up balance
Dumpling point is, it is necessary to which complete machine displacement adjusts or other adjustment modes no longer at same position, and now setting-up derricking device for counterweight needs
Whipline assists to play to be adjusted, and installation effectiveness is low；Treat arm support or operating mode after changing again by said process afterwards
Assembled.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of crawler crane setting-up balance weight dismounts change certainly
Width device, super lifting working condition change arm support or other when can realize setting-up derricking device for counterweight do not need whipline assist
Can with realize complete machine shift.
To achieve these goals, the technical solution adopted by the present invention is：A kind of crawler crane setting-up balance weight is torn open certainly
Luffing device is filled, including main frame, the main frame front end are connected with principal arm system bottom, setting-up mast bottom and mast bottom,
The principal arm system top is connected to setting-up mast top by setting-up changing-breadth system, and the mast top is connected to by arm-tie
Setting-up mast top, the mast top are also connected to main frame by main changing-breadth system, and the main frame tail end is connected with setting-up and put down
Weight luffing device, the setting-up derricking device for counterweight other end hang arm-tie by setting-up balance weight and are connected to setting-up mast
Top, the setting-up balance weight suspension arm-tie bottom are connected with setting-up balance weight.
Further, the setting-up derricking device for counterweight includes support I, passage oil cylinder, support II and pull-up steel wire rope,
Described pull-up steel wire rope one end is connected to main frame by pull-up pin joint II, and the other end is connected to support by pull-up pin joint I
Ⅰ；Described one end of support I is hinged to main frame tail end, and the other end of support I is hinged to support II, and the other end of support II connects
Setting-up balance weight suspension arm-tie is connected to, the middle part of support I is also connected to support II by passage oil cylinder.
Further, cylinder pedestal is equipped with the support I, passage oil cylinder is connected by cylinder pedestal；The abdomen of support II
Portion is fixed with cylinder connector, is hinged by cylinder connector and passage oil cylinder head.
The beneficial effects of the invention are as follows：Crawler crane super-starting balance weight luffing device can be met completely from dismounting, and completely
Sufficient crawler crane super lifting working condition changes arm support, changes the convenient displacement of crawler crane under the installation operating mode such as operating mode, improves
The dismounting convenience of crawler crane setting-up derricking device for counterweight and complete machine, auxiliary hoist is saved, reduce labor intensity, carry
High installation effectiveness.
