Description
Technical field
The utility model is related to a kind of boom device, and in particular to a kind of jack up fixes the pitching luffing lifting of tower crane
Arm assembly.
Background technology
Tower crane is a kind of crane gear also known as derrick crane the most frequently used on construction site, with a section spreading,
For hanging the raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe.Tower crane is a kind of essential on building site
Equipment.The function of tower crane point is subject to the upper load that arm support drawstring and counter-jib drawstring are transmitted, and by turning round pylon, turning
The structure member formula of platform, bearing etc. directly passes to tower body structure by turntable.There is truncated cone pillar from a liter tower top, lean forward or hypsokinesis
Truncated cone pillar, herringbone posture and diagonal brace posture.Every upper rotary tower crane is both needed to set balance weight, and its function is supporting balance weight, is used
With hoisting moment trimming moment in opposite direction in terms of with effect required on Construction designing.In addition to balance weight, also Chang Qi
Afterbody installs lifting mechanism.Why homostasis weight is placed in counter-jib tail end to raising together, first can play part and match somebody with somebody recast
With, second increase the distance between rope reel and pinnacle of a pagoda guide wheel, with the row of sharp steel wire rope around and avoid occurring disorder cable phenomenon.Balance weight
Consumption and counter-jib length inversely, and balance between arm lengths and jib length and there is certain proportion pass
System.Counterpoise is considerable, and light-duty tower crane typically at least wants 3 ~ 4t, and heavy wants nearly 30t.
The jib length of existing derrick crane can not be adjusted as needed, in-convenience in use, and due to
The radius of gyration of derrick crane is larger, broad covered area, so the high vacant building in crane hanging component working range may hinder
Hinder the lifting work of crane so that weight can not be sent to required another location by crane from a position exactly,
So as to influence the accuracy that crane hanging component works；Therefore it provides a kind of compact conformation, easy to use, job area are big, lifting
The liftable derrick crane that arm can stretch is very important.
Utility model content
Technical problem to be solved in the utility model is that the jib length of existing derrick crane can not be according to need
It is adjusted, it is therefore intended that a kind of tight device of work piece positioning is provided, solves the jib length of existing derrick crane
The problem of can not being adjusted as needed.
The utility model is achieved through the following technical solutions：
A kind of jack up fixes the pitching luffing boom device of tower crane, including base, and the top of described base is set
Tower body, the top of described tower body is provided with tower top, and operating room, described operating room are provided between described tower body and tower top
Both sides be respectively arranged with counter-jib and crane arm, described counter-jib and the external part of crane arm pass through pull bar and tower top respectively
It is connected, counterweight running gear is provided with described counter-jib, described crane arm includes the first crane arm and the second crane arm
Connected by pull bar and tower top, the second described crane arm is slidably connected relative to the first crane arm, and position is slided in maximum
Rotating device is provided with shifting.The jib length of existing derrick crane can not be adjusted as needed, in-convenience in use,
And because the radius of gyration of derrick crane is larger, broad covered area, so the high-altitude building in crane hanging component working range
Thing may hinder the lifting work of crane so that weight can not be sent to required another by crane from a position exactly
One position, so as to influence the accuracy that crane hanging component works；Therefore it provides a kind of compact conformation, easy to use, job area
Greatly, the liftable derrick crane that crane arm can stretch is very important.The second crane arm can be with the utility model
Relative to the first crane arm telescopic slide, second crane arm can be shunk in the case of the crane hanging component radius of clean-up is less
To inside the first crane arm, in the case where the lifting radius of clean-up of crane is larger, the second crane arm can be made as needed
Along the first crane arm inwall stretching motion, some buildings pair in crane hanging component working range so can be effectively prevented
Lift the obstruction of work；And rotating device is provided with, when tower crane does not need work, crane arm can be shunk and rotated.With
Power unloads the mode of power, the service life of the protection mechanical devices of maximum possible.
Described counter-jib and crane arm are fixedly connected between operating room.Preferably, this is to live to steadiness
Dynamic connection.
The moving cart of lower section connection lifting coupler body is provided with the second described crane arm.Lifting coupler body has been used for lift heavy
Thing, moving cart is used for sliding position.
The moving cart is connected with the pulley being arranged on crane arm, and the surface of the pulley is arranged with noise reduction wheel case,
Noise is reduced, operating personnel itself is accomplished by giving the relatively quiet ring of operating personnel one by intercom dialogue, first in high-altitude
Border, the second reduction noise is that neighbouring resident or crossing personnel weaken the effect.
First crane arm and the second crane arm connect rotating device, and the second crane arm can be rotated up around junction
60 °, it is most rational that this specific angle, which is arranged on 60 °, and it is best that this angle unloads power effect.Avoid because not working
When, service life is laterally decreased for a long time.It can also collapse by wind direction or natural cause, 60 ° up of this folding can reduce this
The individual possibility collapsed, consolidates performance more preferable.
The utility model compared with prior art, has the following advantages and advantages：
1st, a kind of jack up of the utility model fixes the pitching luffing boom device of tower crane, in crane hanging component work half
Second crane arm can be retracted in the case of footpath is less inside the first crane arm, it is larger in the lifting radius of clean-up of crane
In the case of, it can make the second crane arm along the first crane arm inwall stretching motion as needed, so can effectively prevent
Obstruction of some buildings to lifting work in crane hanging component working range；And rotating device is provided with, in tower crane not
When needing work, crane arm can be shunk and rotated.In the way of power unloads power, the use year of the protection mechanical devices of maximum possible
Limit；
2nd, a kind of jack up of the utility model fixes the pitching luffing boom device of tower crane, and the moving cart is with setting
Pulley connection on crane arm, the surface of the pulley is arranged with noise reduction wheel case, reduces noise, operating personnel itself is in high-altitude
It is accomplished by by intercom dialogue, first gives the relatively quiet environment of operating personnel one, and second reduces noise for neighbouring resident
Or crossing personnel weakens the effect；
3rd, a kind of jack up of the utility model fixes the pitching luffing boom device of tower crane, and the second crane arm can be around connection
Place, rotates up 60 °, and it is most rational that this specific angle, which is arranged on 60 °, and it is best that this angle unloads power effect.Avoid
Because when not working, service life is laterally decreased for a long time.It can also collapse by wind direction or natural cause, this folding gets on
60 °, this possibility collapsed can be reduced, performance is consolidated more preferable.
