Long, inner climbing type tower crane area coverage is bigger than external climbing tower crane.The shortcoming of inner climbing type tower crane is dismounting
Difficulty is big, and after architecture construction terminates, tower crane to be disintegrated on top layer, is hoisted to ground.
Roofing crane of the prior art is to utilize cable wind rope to be anchored on roof to realize internally
The flooring of climbing tower machine disintegrates, handling, need to arrange array cable wind rope, if the region area of flooring is little,
Layout cable wind rope is extremely difficult, and cable wind rope is easily wrapped on suspension hook and handling thing, gives lifting
Fortune brings the biggest security risk.
Utility model content
The purpose of this utility model is to provide a kind of roofing crane, it is possible to breaks away from and depends on cable wind rope
Rely, it is achieved the anchoring on the area flooring of zonule is installed.
For achieving the above object, this utility model be the technical scheme is that a kind of roofing
Crane, including central authorities' vertical frame and crane arm, described central authorities pass through rigid support in vertical frame both sides respectively
Frame is supported, and the upper end of described rigid cage is connected with central authorities vertical frame tops, and its lower end can be with
Built-in fitting is anchored fixing.
Preferably, the angle projected at horizontal plane between said two rigid cage is 90 ° ± 5 °.
Preferably, described central authorities vertical frame top is provided with rotation top cap, and described rigid cage passes through pin
Axle is hinged with described rotation top cap.
Preferably, the main body of described rigid cage is made up of standard knot；Described main body upper end connects
Having the extremity lattice frame of rectangular pyramid shape, its lower end connects has the length can being adjusted its length to adjust
Joint frame.
This utility model has the advantages that and carries out propping up to central authorities' vertical frame by rigid cage
Support replaces cable wind rope, flexible support is become rigid support, not only makes support more solid and reliable,
And rigid cage is easy for installation, only need to select according to the height of floor area and central authorities' vertical frame
The rigid cage of appropriate length just can realize installing, and is not limited by floor area, improves roofing
The adaptability of crane, owing to without cable wind rope, substantially increasing the safety of handling.Two
The angle between bracing frame at the angle of horizontal plane projection being is 90 ° ± 5 ° so that central authorities' vertical frame and two
Firm triangular pyramid is defined between individual bracing frame, more firm, it is unlikely to deform.Rigid support
Frame rigid cage is hinged with described rotation top cap by bearing pin, makes angle regulation convenient.Just
The length adjustment frame of property bracing frame lower end makes length adjustment convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of roofing crane, including central authorities' vertical frame 1 and crane arm 4, institute
State central authorities vertical frame 1 both sides to be supported by rigid cage 2 respectively, said two rigid support
Angle between frame 2 is 90 ° ± 5 °, and in the present embodiment, two rigid cage 2 project at horizontal plane
Angle be 90 °, in FIG another rigid cage 2 by central authorities vertical frame block, Gu Tuzhong
Not shown.The upper end of described rigid cage 2 is connected with central vertical frame 1 top, and described central authorities erect
Frame 1 top is provided with draw-bar seat 3, and described central authorities vertical frame 1 top is provided with rotation top cap 3, described just
Property bracing frame 2 hinged with described rotation top cap 3 by bearing pin, the lower end of rigid cage 2 can be with
Built-in fitting is anchored fixing.The main body of described rigid cage 2 is made up of standard knot；In described main body
End connects the extremity lattice frame of rectangular pyramid shape, and its lower end connects to be had and can be adjusted its length
Length adjustment frame 11.
In technique scheme, it is supported replacing to central authorities' vertical frame 1 by rigid cage 2
Cable wind rope, becomes rigid support by flexible support, not only makes support more solid and reliable, Er Qiegang
Property bracing frame easy for installation, only need to select properly according to the height of floor area and central authorities' vertical frame 1
The rigid cage 2 of length becomes can realize installation, is not limited by floor area, improves roofing and rise
The adaptability of heavy-duty machine, owing to without cable wind rope, substantially increasing the safety of handling.Two
Angle between support 2 is 90 ° so that define between central authorities' vertical frame 1 and two bracing frames 2
Firm triangular pyramid, more firm, it is unlikely to deform.Rigid cage 2 passes through bearing pin with described
Rotate top cap 3 hinged, make angle regulation convenient.The length adjustment of rigid cage 2 lower end
Frame 11 makes length adjustment convenient.
Further, described central authorities vertical frame 1 lower end connects turntable 8, and turntable 8 is by above it
Slew gear 5 be driven, on described turntable 8, level connection joint has postbrachium 7；Described crane arm
