Description

A kind of derrick crane hoist rope passes around system
Technical field
This utility model relates to derrick crane technical field, especially relates to a kind of derrick crane hoist rope and wears System for winding.
Background technology
Derrick crane hoist rope passes around system, is that derrick crane completes to hoist the vitals of operation.Tower Crane rope passes around system and includes multiple pulley and directive wheel.Hoist rope passes around the system steel wire by the hoisting machine that hoists Restrict and be sent to the fixed pulley of mobile dolly through leading block, by fixed pulley, steel wire rope is connected with hook gear.At present, mobile The minimum employing of dolly four pulley structures.Quantity is too much, and the structure making mobile dolly is more complicated, and own wt is heavier, affects tower The performance of formula crane.
Utility model content
In order to overcome the defect of prior art, this utility model provides a kind of structure more reasonably derrick crane lifting Steel wire rope passes around system.
In order to solve above-mentioned technical problem, this utility model provides a kind of derrick crane hoist rope to pass around system, Including hoist rope reel;The steel wire rope that one end is connected with described hoist rope reel;It is arranged on derrick crane Tower top leading block;The jib leading block being arranged on elevator boom rack;The dolly leading block that is arranged on amplitude variation trolley, One fixed pulley and the second fixed pulley;The first movable pulley of being arranged on hook mechanism, the second movable pulley, the 3rd movable pulley;With rise The Fang Niu mechanism that weighing arm frame connects;The other end of described steel wire rope walks around tower top leading block, jib leading block, dolly successively With described anti-torsion machine after leading block, the first movable pulley, the second movable pulley, the first fixed pulley, the 3rd movable pulley, the second fixed pulley Structure connects.
As improving technical scheme further, the derrick crane hoist rope that this utility model provides passes around system, The crossbeam that the middle part of described amplitude variation trolley is provided with described amplitude variation trolley two ends is connected, along the longeron that elevator boom rack is axial arranged; Described first fixed pulley is arranged on the first end of described longeron;Described dolly leading block and the second fixed pulley are arranged on described vertical The other end of beam.
As improving technical scheme further, the derrick crane hoist rope that this utility model provides passes around system, Described longeron is welded with reinforcement gusset with the crossbeam junction at amplitude variation trolley two ends.
As improving technical scheme further, the derrick crane hoist rope that this utility model provides passes around system, Described dolly leading block and the second fixed pulley corotation axle, dolly leading block and the second fixed pulley are arranged in parallel.
In the case of not conflicting, above-mentioned improvement project can be implemented alone or in combination.
The technical scheme that this utility model provides, dolly leading block and the second fixed pulley are arranged in parallel, and make amplitude variation trolley At the stress balance that elevator boom rack is axial;Mobile dolly uses three pulley structures, makes the simple in construction of mobile dolly, reduces certainly Heavy sensation of the body amount.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, constitutes the part of the application, of the present utility model Schematic description and description is used for explaining this utility model, is not intended that improper restriction of the present utility model.At accompanying drawing In:
Fig. 1 is the structural representation that embodiment derrick crane hoist rope passes around system;
Fig. 2 is the main TV structure schematic diagram that embodiment derrick crane hoist rope passes around the amplitude variation trolley of system;
Fig. 3 is the plan structure schematic diagram that embodiment derrick crane hoist rope passes around the amplitude variation trolley of system.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
Derrick crane hoist rope as shown in Figure 1 to Figure 3 passes around system, including hoist rope reel 1, one end The steel wire rope 12 being connected with described hoist rope reel 1, the tower top leading block 2 being arranged on derrick crane, it is arranged at Jib leading block 3 on elevator boom rack, dolly leading block the 5, first fixed pulley 9 and second being arranged on amplitude variation trolley 4 Fixed pulley 10, first movable pulley the 6, second movable pulley the 7, the 3rd movable pulley 8 being arranged on hook mechanism, it is connected with elevator boom rack Fang Niu mechanism 11, the other end of described steel wire rope 12 walk around successively tower top leading block 2, jib leading block 3, dolly guide Prevent with described after pulley the 5, first movable pulley the 6, second movable pulley the 7, first fixed pulley the 9, the 3rd movable pulley the 8, second fixed pulley 10 Turn round mechanism 11 to connect.
Alternatively, the derrick crane hoist rope that this utility model provides passes around system, and the middle part of amplitude variation trolley 4 sets Have be connected with the crossbeam at amplitude variation trolley 4 two ends, along the axial arranged longeron 13 of elevator boom rack, described first fixed pulley 9 is arranged on First end of described longeron 13;Described dolly leading block 5 and the second fixed pulley 10 are arranged on the other end of described longeron 13.Institute The crossbeam junction stating longeron 13 and amplitude variation trolley 4 two ends is welded with reinforcement gusset 14.Described dolly leading block 5 and second is fixed Pulley 10 corotation axle, dolly leading block 5 and the second fixed pulley 10 are arranged in parallel.
Dolly leading block 5 and the second fixed pulley 10 are arranged in parallel, and make amplitude variation trolley 4 put down in the stress that elevator boom rack is axial Weighing apparatus.Mobile dolly uses three pulley structures, makes the simple in construction of mobile dolly, reduces own wt.
This utility model is not limited to above preferred implementation, also can limit in this utility model claim and description Spirit in, carry out conversion and the improvement of various ways, can solve same technical problem, and technique effect expected from acquirement, Therefore do not repeat.Those of ordinary skill in the art can from this utility model disclosure directly or all schemes of associating, As long as within the spirit that claim limits, falling within protection domain of the present utility model.
