Description
Technical field
The present invention relates to a kind of lifting equipment, more particularly to a kind of tower crane.
Background technology
The danger for often making tower crane presence tilt and topple over when existing tower crane progress large-sized object lifting, and tower
The process for occurring that center of gravity is gradually offset before toppling over is hung in, whole process is the process of continuation.
The content of the invention
It is an object of the invention to provide a kind of tower crane, can find the situation of tower crane centre-of gravity shift in time, effectively prevent
Topple over.
In order to achieve the above object, this invention takes following technical scheme：
A kind of tower crane, including fixed tower, the panoramic table of fixed tower upper end is arranged on, is arranged on the rotation of panoramic table upper end
Tower body, and it is arranged on the arm held with rotary column, counter-jib, OPS, tower cap；The end of arm and counter-jib passes through
Drag-line is connected with tower cap upper end；Hook and hoist engine are provided with arm；Balancing weight is provided with counter-jib；Fixed tower both sides
Ground on be symmetrically fixed with two columns, hydraulic cylinder is provided with column, the piston rod of hydraulic cylinder is connected with fixed tower；
Panoramic table bottom is provided with generating laser downwards, and one is provided with the ground of the underface of the generating laser
One laser pickoff, the both sides of first laser receiver respectively set a second laser receiver；Panoramic table, hoist engine, hydraulic pressure
Control system in cylinder, laser pickoff and OPS is electrically connected with.
In described tower crane, the railcar being reciprocally moveable is provided with the counter-jib, balancing weight is fixed on railcar
On.
In described tower crane, the height of the hydraulic cylinder is not less than 1/3rd of fixed tower height.
Beneficial effect：
The invention provides a kind of tower crane, and when its center of gravity shifts, first laser receiver can not receive Laser emission
The signal that device is sent, occur to arrive control system so as to form caution signal, receive maintenance down after caution signal；Work as centre-of gravity shift
When receiving the signal that generating laser is sent to second laser receiver, control system controls liquid according to the signal condition of reception
Cylinder pressure work provides Auxiliary support, prevents tower crane from toppling over.The tower crane can find the situation of tower crane centre-of gravity shift in time, effectively anti-
Only topple over.
Brief description of the drawings
Fig. 1 is the structural representation of tower crane provided by the invention.
Embodiment
The present invention provides a kind of tower crane, to make the purpose of the present invention, technical scheme and effect clearer, clear and definite, below
The present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
Referring to Fig. 1, a kind of tower crane provided by the invention, including fixed tower 1, it is arranged on returning for fixed tower upper end
Turntable 2, is arranged on the rotation tower body 3 of panoramic table upper end, and is arranged on the arm 4 held with rotary column, counter-jib 5, manipulation
Room 6, tower cap 7；The end of arm and counter-jib is connected by drag-line 8 with tower cap upper end；Hook 9 and elevator are provided with arm
Machine 10；Balancing weight 11 is provided with counter-jib；Two columns 12 are symmetrically fixed with the ground of fixed tower both sides, on column
Hydraulic cylinder 13 is provided with, the piston rod of hydraulic cylinder is connected with fixed tower；Panoramic table bottom is provided with laser hair downwards
Emitter 14, a first laser receiver 15, first laser receiver are provided with the ground of the underface of the generating laser
Both sides respectively set a second laser receiver 16；In panoramic table, hoist engine, hydraulic cylinder, laser pickoff and OPS
Control system is electrically connected with.
When its center of gravity shifts, first laser receiver can not receive the signal that generating laser is sent, so as to
Form caution signal to occur to arrive control system, receive maintenance down after caution signal；When centre-of gravity shift to second laser receiver
When receiving the signal that generating laser is sent, control system controls hydraulic cylinder works to provide auxiliary according to the signal condition of reception
Support, prevents tower crane from toppling over.The tower crane can find the situation of tower crane centre-of gravity shift in time, effectively prevent from toppling over.
Further, the railcar 17 being reciprocally moveable is provided with the counter-jib 5, balancing weight 11 is fixed on railcar
On.When tower crane zero load, by railcar self-balanced upper rotary, the center of gravity of tower crane is set to fall in rotation tower body.
Preferably, the height of the hydraulic cylinder 13 is not less than 1/3rd of the height of fixed tower 1.
It is understood that for those of ordinary skills, can be with technique according to the invention scheme and its hair
Bright design is subject to equivalent substitution or change, and all these changes or replacement should all belong to the guarantor of appended claims of the invention
Protect scope.
