Description
Technical field
This utility model relates to a kind of tower crane safety device, particularly a kind of for tower crane amplitude variation trolley Anti-rope drop safety guard.
Background technology
Tower crane amplitude variation trolley is the key component of tower crane metal structure, operationally, usually carriage amplitude varying rope is caused to be beated due to inertia, easily produce steel wire rope and jump out the dangerous situation of race, tower crane safe operation is caused and has a strong impact on, although occurring in that some preventers at present, but effect being not ideal.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, it is provided that a kind of easy for installation, simple in construction, uses safe tower crane amplitude variation trolley anti-off rope device.
The purpose of this utility model is achieved through the following technical solutions: a kind of tower crane amplitude variation trolley anti-off rope device, including rope skipping preventing roller, tower crane trolley idler wheels, fixed support, rolling bearing and support shaft, connected by rolling bearing in the both sides of described rope skipping preventing roller and have support shaft, having support bracket fastened one end in described support shaft by split pin connection, the described support bracket fastened other end is by being connected with tower crane trolley idler wheels with support shaft by rolling bearing.
Further improvement of the utility model is: described Anti-rope drop pulley and rolling bearing are assembled by transient mode, saves the set-up time, and frictional force is little, extends service life.
Further improvement of the utility model is: described support shaft and rolling bearing are assembled by the mode of being full of, and it will not be made to move axially and move radially, fixing more firm.
This utility model compared with prior art has the advantage that
There is compact conformation, use and easy for installation, more safe and reliable, run more smooth and easy, extend the service life of tower crane.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is left view of the present utility model；
Label in figure: 1-rope skipping preventing roller, 2-fixed support, 3-rolling bearing, 4-support shaft, 5-split pin, 6-tower crane trolley idler wheels.
Detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
As Fig. 1-2 shows the embodiment of this utility model a kind of tower crane amplitude variation trolley anti-off rope device: include rope skipping preventing roller 1, tower crane trolley idler wheels 6, fixed support 2, rolling bearing 3 and support shaft 4, connected by rolling bearing 3 in the both sides of described rope skipping preventing roller 1 and have support shaft 4, having one end of fixed support 2 in described support shaft 4 by split pin 5 connection, the other end of described fixed support 2 is by being connected with tower crane trolley idler wheels 6 with support shaft 4 by rolling bearing 3.
Anti-rope drop pulley 1 and rolling bearing 3 are assembled by transient mode, save the set-up time, and frictional force is little, extends service life；Described support shaft 4 and rolling bearing 3 are assembled by the mode of being full of, and it will not be made to move axially and move radially, and fixing more firm, tower crane lifting steel wire rope is between anticreep rope sheave 1 and tower crane trolley idler wheels 6 motion all the time.
This utility model has compact conformation, use and easy for installation, more safe and reliable, runs more smooth and easy, the advantage extending the service life of tower crane.
