Description
Technical field
The present invention relates to the structure that a kind of tower crane peace tears balance weight open, more particularly to a kind of tower crane self installation and oneself dismounting to balance
The structure of weight.
Background technology
Tower crane balance weight is general cylinder iron or armored concrete is fabricated, and is placed on counter-jib afterbody, keeps tower crane work
Equalising torque when making.The installation and removal of current tower crane, mode the most universal are using crane gears such as truck cranes, by certain
Step slings each structural member of tower crane, and then completes the assembly and disassembly of tower crane complete machine.The handling of balance weight are also such.
But current balance weight handling mode has some following deficiency：First, the rent outside amount paid need to be used using truck crane
With expense, increase cost.Second, in some Special complex operating modes, it is difficult to recycle truck crane to complete the handling of balance weight：Than
Such as, when fabricating yard is narrow and small, truck crane operation inconvenience；For another example, tower crane sometimes for change arm or disintegration is completed in the air, at this moment
Disengaging section balance weight is needed, now balance weight may be up to more than 200m apart from ground level, in this case, truck crane limit
In arm stroke, it is difficult to complete the lifting of balance weight.
It would therefore be highly desirable to design, a kind of more traditional balance weight handling mode is more economical, operation is also more flexible new
Tower crane self installation and from dismounting counterweight structure form.
The content of the invention
For above-mentioned existing technical problem, the present invention provides a kind of tower crane self installation and the structure from dismounting balance weight,
To have more economy and flexibility.
To achieve the above object, the present invention provides a kind of tower crane self installation and from the structure for dismantling balance weight, including installs
Lifting mechanism on counter-jib, installed in the lifting pulley of tower top, installed in counter-jib outer end hang certainly counter weight device and
Steel wire rope；The described support for hanging counter weight device certainly and including being fixedly connected with hanging counter weight device certainly, rack-mount first
Top sheave and the second top sheave, and the lower sheave below both, and lower sheave removably connects balance weight；Described
Steel wire rope through lifting pulley, the second top sheave, lower sheave, the first top sheave wraparound and is fixed on successively from lifting mechanism
On lifting mechanism, in this way, can be achieved smoothly to rise or put down balance weight by assembly pulley using jack up unit.
Further, described lower sheave is removably connected by bearing pin with balance weight.
Further, the tail end of described steel wire rope is fixed on the cover of wedge of lifting mechanism.
The present invention is balanced by the use of the lifting mechanism of tower crane itself as power source with a set of handling on counter-jib
Cooperation is put in refitting, slings balance weight in the case of not by outside crane gear, and then realizes pacifying certainly for tower crane balance weight
Dress and certainly dismounting.The technical scheme has following advantage：
1) present apparatus is simple in construction, cost is cheap, can replace extra hanging device completely, realizes the self installation of balance weight
With from dismantling, reduce cost of equipment, reduce cost, improve efficiency of construction, more economy；
2) device operation is flexible, solve thes problems, such as that balance weight installation or removal are difficult under Special complex operating mode,
It is applicable more extensive.
Brief description of the drawings

In figure：11st, lifting mechanism, 12, lifting pulley, 13, steel wire rope, 14, hang counter weight device certainly, 15, balance weight, 16,
Counter-jib, 21, support, the 22, first top sheave, the 23, second top sheave, 24, lower sheave.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention includes the lifting mechanism 11 being arranged on counter-jib 16, installed in the lifting pulley of tower top
12, hanging counter weight device 14 certainly, be lifted on from the balance weight 15 and steel wire for hanging the lower section of counter weight device 1 installed in the outer end of counter-jib 16
Rope 13.
As shown in Figures 2 and 3, it is fixed on by support 21 on counter-jib 16 from hanging counter weight device 14.It is included with hanging certainly
The support 21 that counter weight device 14 is fixedly connected, the first top sheave 22 and the second top sheave 23, Yi Jiwei on the stent 21 are installed
Lower sheave 24 below both, lower sheave 24 lift balance weight 15 by bearing pin.
As shown in figures 1 and 3, steel wire rope 13 sets out from lifting mechanism 11, successively through lifting pulley 12, the second top sheave
23rd, lower sheave 24, on the wraparound lifting mechanism 11 of the first top sheave 22.
When balance weight 15 is installed, balance weight 15 is first placed in the lower section of counter-jib 16, steel wire rope 13 is gone out by lifting mechanism 11
Hair, sequentially passes through lifting pulley 12, the second top sheave 23, lower sheave 24, the first top sheave 22, and wraparound lifting mechanism 11 goes out, and
The tail end of steel wire rope 13 is fixed on the cover of wedge of lifting mechanism 11.Then, lower sheave 24 is put down using lifting mechanism 11, uses bearing pin
It is connected with balance weight 15.Balance weight 15 is lifted into horizontal level again, installation personnel guides on counter-jib 16, will
Balance weight 15 is fixed in counterweight support.Then, according to each piece of counterweight of the same lifting of preceding method and install.
It is identical when the baudrier of steel wire rope 13 is with installation balance weight 15 when dismantling balance weight 15.With bearing pin by lower sheave 24
It is connected with balance weight 15, lower sheave 24 and connected balance weight 15 is slowly put down using lifting mechanism 11, until balance weight
15 steady landings.
Power source is so used as using the lifting mechanism 11 of tower crane itself, by hanging weight-balancing device certainly on counter-jib 16
14 effects, it just can complete the self installation of balance weight 15 and dismantle certainly.
