Description
Technical field
The present invention relates to a kind of boom device, and in particular to it is a kind of can on-load luffing lifting arm elevator apparatus.
Background technology
Tower crane is a kind of crane gear the most frequently used on construction site also known as derrick crane, 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 requisite 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, lean forward or hypsokinesis from a liter tower top
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
The trimming moment in opposite direction with hoisting moment 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 with 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 disorder cable phenomenon.Balance weight
Consumption and counter-jib length inversely, and balance and there is certain proportion between arm lengths and jib length and close
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 cannot 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 cannot be sent to required another location from a position by crane exactly,
So as to the accuracy for affecting crane hanging component to work；Therefore it provides a kind of compact conformation, easy to use, job area be big, lifting
The liftable derrick crane that arm can stretch is very important.
The content of the invention
The technical problem to be solved is that the jib length of existing derrick crane cannot enter as needed
Row adjustment, it is therefore intended that provide a kind of work piece positioning tight device, the jib length for solving existing derrick crane cannot
The problem being adjusted as needed.
The present invention is achieved through the following technical solutions：
It is a kind of can on-load luffing lifting arm elevator apparatus, including base, the top of described base arrange tower body, described
The top of tower body is provided with tower top, and operating room is provided between described tower body and tower top, and the both sides of described operating room are distinguished
The external part for being provided with counter-jib and crane arm, described counter-jib and crane arm is connected with tower top by pull bar respectively, described
Counter-jib on be provided with counterweight running gear, described crane arm includes that the first crane arm and the second crane arm pass through pull bar
Connect with tower top, the second described crane arm is slidably connected relative to the first crane arm, and at maximum slide displacement is provided with rotation
Rotary device.The jib length of existing derrick crane cannot be adjusted as needed, in-convenience in use, and due to tower
The radius of gyration of formula crane is larger, broad covered area, so the high vacant building in crane hanging component working range may hinder
The lifting work of crane so that weight cannot be sent to required another location from a position by crane exactly, from
And affect the accuracy of crane hanging component work；Therefore it provides a kind of compact conformation, easy to use, job area be big, crane arm
The liftable derrick crane that can be stretched is very important.In the present invention, the second crane arm can be relative to the first lifting
Arm telescopic slide, can be retracted to the second crane arm in the first crane arm in the case of the crane hanging component radius of clean-up is less
Portion, in the case where the lifting radius of clean-up of crane is larger, can make the second crane arm along the first crane arm as needed
Wall stretching motion, can so be effectively prevented resistance of some buildings to lifting work in crane hanging component working range
Hinder；And whirligig is provided with, when tower crane does not need work, crane arm can be shunk and be rotated.In the way of power unloads 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 are 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 talking with by intercom in high-altitude, first gives operating personnel one relatively quiet ring
Border, the second reduction noise are that neighbouring resident or crossing personnel weaken the effect.
First crane arm and the second crane arm connection whirligig, the second crane arm can be rotated up around junction
60 °, it is most rational that this specific angle 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.Can also collapse through wind direction or natural cause, 60 ° up of this folding can reduce this
The individual possibility collapsed, consolidates performance more preferable.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention it is a kind of can on-load luffing lifting arm elevator apparatus, in the case of the crane hanging component radius of clean-up is less
Second crane arm can be retracted to inside the first crane arm, in the case where the lifting radius of clean-up of crane is larger, can be with
Make the second crane arm along the first crane arm inwall stretching motion as needed, can so be effectively prevented in crane hanging component work
Obstruction of some buildings to lifting work in the range of work；And whirligig is provided with, when tower crane does not need work, can be with
Crane arm is shunk and is rotated.In the way of power unloads power, the service life of the protection mechanical devices of maximum possible；
2nd, the present invention it is a kind of can on-load luffing lifting arm elevator apparatus, the moving cart and the cunning being arranged on crane arm
Wheel connection, the surface of the pulley are arranged with noise reduction wheel case, reduce noise, and operating personnel itself is accomplished by by intercom in high-altitude
Dialogue, first gives operating personnel one relatively quiet environment, and the second reduction noise is that neighbouring resident or crossing personnel mitigate
Affect；
3rd, the present invention it is a kind of can on-load luffing lifting arm elevator apparatus, the second crane arm can be rotated up around junction
60 °, it is most rational that this specific angle 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.Can also collapse through wind direction or natural cause, 60 ° up of this folding can reduce this
The individual possibility collapsed, consolidates performance more preferable.
