Description
Technical field
The utility model is related to a kind of supporting structure, and in particular to a kind of pivoting support structure on rotary type tower next time.
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 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 be rise when need raise section on regulation, it is necessary at least 2 operating personnel climb to rise section on, adjusted by crane arm
One support section, is installed in high-altitude manually, very dangerous.
Utility model content
Technical problem to be solved in the utility model is that the tower body of existing low-level slewing tower crane is highly difficult root
According to need carry out lift adjustment, it is therefore intended that provide a kind of pivoting support structure on rotary type tower next time, solve it is existing under
The tower body of rotary tower crane is highly difficult the problem of carrying out lift adjustment as needed.
The utility model is achieved through the following technical solutions：
A kind of pivoting support structure on rotary type tower next time, including base, the upper surface of the base is provided with hydraulic pressure
Bracket is provided with above lifter, described hydraulic pressure lifting device, the upper surface of described bracket is provided with tower body, described tower
The top of 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 set respectively
Counter-jib and crane arm are equipped with, described counter-jib and the external part of crane arm are connected by pull bar with tower top respectively.It is existing
The tower body of low-level slewing tower crane is highly difficult to carry out lift adjustment as needed, in-convenience in use, subject matter is rise
When need raise section on regulation, it is necessary at least 2 operating personnel climb to rise section on, pass through crane arm adjust one support section, hand
Move and installed in high-altitude, it is very dangerous.The utility model adds hydraulic pressure lifting device to solve this problem, is arranged on bottom
Seat upper surface.When needing adjusting position, the height of crane is controlled by adjusting the reduction of the hydraulic pressure lifting device on base or raising
Degree, adds or unloads support frame in bottom, reaches the effect of same change height, but operating personnel run in bottom surface, increase
Process the security made.
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
Require high than aerial handling before with the equipment on basis, increase bracing piece be in order to increase security, and bracing piece it
Between there is one side to be reserved enough position turnover, facilitate operating personnel to install.
Described crane arm includes the first crane arm and the second crane arm and connected by pull bar and tower top, and 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 in the case of the machine lifting radius of clean-up is less inside the first crane arm, in the lifting of crane
In the case that the radius of clean-up is larger, it can make the second crane arm along the first crane arm inwall stretching motion as needed, so may be used
Effectively to prevent 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 utility model compared with prior art, has the following advantages and advantages：
1st, a kind of pivoting support structure on rotary type tower next time of the utility model, adds hydraulic pressure lifting device, is arranged on
Base upper surface.When needing adjusting position, crane is controlled by adjusting the reduction of the hydraulic pressure lifting device on base or raising
Highly, support frame is added or unloaded in bottom, reaches the effect of same change height, but operating personnel run in bottom surface,
Increase the security of work；
2nd, a kind of pivoting support structure on rotary type tower next time of the utility model, increase bracing piece is to increase safety
Property, and it is reserved enough position turnover to have one side between bracing piece, facilitates operating personnel to install；
3rd, a kind of pivoting support structure on rotary type tower next time of the utility model, the second crane arm can be relative to first
Crane arm telescopic slide, the first lifting can be retracted in the case of the crane hanging component radius of clean-up is less by the second crane arm
Inside 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 lifting
Arm inwall stretching motion, so can effectively prevent that some buildings are to lifting work in crane hanging component working range
Hinder.
