Description
Technical field
The present invention relates to a kind of supporting structure, and in particular to a kind of foundation reduces structure in the moment of flexure that tower body is turned round.
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 tower body of existing low-level slewing tower crane is highly difficult to carry out lift adjustment as needed, in-convenience in use,
Subject matter is to need to raise when raising adjust on section, needs at least 2 operator to climb on rising section, is adjusted by crane arm
One supports section, installs in high-altitude manually, very dangerous.
The content of the invention
The technical problem to be solved is that the tower body of existing low-level slewing tower crane is highly difficult according to need
Lift adjustment to be carried out, it is therefore intended that a kind of moment of flexure reduction structure set up in tower body revolution is provided, existing lower revolution is solved
The tower body of derrick crane is highly difficult the problem for carrying out lift adjustment as needed.
The present invention is achieved through the following technical solutions：
A kind of moment of flexure reduction structure set up in tower body revolution, including base, the upper surface of the base are provided with hydraulic lifting
Device, is provided with bracket above described hydraulic pressure lifting device, the upper surface of described bracket is provided with tower body, described tower body
Top 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 respectively arranged with
The external part of counter-jib and crane arm, described counter-jib and crane arm is connected with tower top by pull bar respectively.It is existing next time
The tower body of rotary type tower crane is highly difficult to carry out lift adjustment as needed, in-convenience in use, subject matter is needed when raising
Raise, need at least 2 operator to climb on rising section, adjust one to support section by crane arm, exist manually
High-altitude is installed, very dangerous.The present invention increased hydraulic pressure lifting device, be arranged on base upper surface to solve this problem.
When needing adjusting position, the height of crane is controlled by adjusting the hydraulic pressure lifting device reduction on base or raising, in bottom
Addition unloads bracing frame, reaches the effect of same change height, but operator are run in bottom surface, increase the peace of work
Quan Xing.
Bracing piece is provided between the side of described tower body and base.Due to being to operate the function of landing, institute in bottom surface
Had high demands than aerial handling before with the equipment on basis, increase bracing piece be in order to increase safety, and bracing piece it
Between have one side to be reserved enough position turnover, facilitate operator to install.
Described crane arm includes that the first crane arm and the second crane arm are connected by pull bar and tower top, described second
Crane arm is slidably connected relative to the first crane arm.Second crane arm can be relative to the first crane arm telescopic slide, in lifting
Second crane arm can be retracted to inside the first crane arm in the case of the machine lifting radius of clean-up is less, in the lifting of crane
In the case that the radius of clean-up is larger, can make the second crane arm along the first crane arm inwall stretching motion as needed, so may be used
To be effectively prevented obstruction of some buildings to lifting work in crane hanging component working range.
Described counter-jib and crane arm are fixedly connected between operating room.Preferably, this is to live to steadiness
Dynamic connection.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of moment of flexure reduction structure set up in tower body revolution of the present invention, increased hydraulic pressure lifting device, is arranged on base upper table
Face.When needing adjusting position, the height of crane is controlled by adjusting the hydraulic pressure lifting device reduction on base or raising, the bottom of at
Portion adds or unloads bracing frame, reaches the effect of same change height, but operator are run in bottom surface, increase work
Safety；
2nd, the present invention it is a kind of set up tower body revolution moment of flexure reduce structure, increase bracing piece be in order to increase safety, and
There is one side to be reserved enough position turnover between bracing piece, facilitate operator to install；
3rd, a kind of moment of flexure reduction structure set up in tower body revolution of the present invention, the second crane arm can be stretched relative to the first crane arm
Contracting is slided, and the second crane arm can be retracted to inside the first crane arm in the case of the crane hanging component radius of clean-up is less,
In the case where the lifting radius of clean-up of crane is larger, the second crane arm can be made as needed to stretch along the first crane arm inwall
Contracting motion, can so be effectively prevented obstruction of some buildings to lifting work in crane hanging component working range.
