Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figures 2 and 3, the anti-vertical device of a kind of hoist rope of flat-head tower crane, including it is located at boom 1
On rope supporting device and the guiding device 13 on amplitude variation trolley 4, guiding device 13 be leading with the flat square tubes soldering of 120x80
To track；Rope supporting device is C-shaped, and one end of rope supporting device is connect by pivot pin with boom lower edge 6, and the other end passes through Tuo Sheng mechanism
It is fixed on 2 lower section of hoist rope, is connected with leading block 7 on the inside of one end boom 1 of rope supporting device.
Fig. 4 is in the present invention when the state of trolley rope supporting device when amplitude peak or minimum radius position move about
Figure.
Fig. 5 is the state diagram of rope supporting device and amplitude variation trolley when amplitude variation trolley will be by support rope position in the present invention.
As shown in Figure 4 and Figure 5, the working principle of technical solution of the present invention is: when amplitude variation trolley 4 in amplitude peak or most
Position moves about formula by a small margin, and rope supporting device is in support rope form state and subtracts so that hoist rope 2 is in a fixed position
Small sag height, as shown in Figure 4.When amplitude variation trolley 4 will be by support rope position, leading block 7 starts and guide rail contact,
Leading block 7 is introduced into introduction guiding position, and rope supporting device starts to be detached from hoist rope 2 at this time, when rope supporting device is completely de-
After hoist rope 2, amplitude variation trolley 4 can be by rope supporting device position, as shown in Figure 5 at this time.When amplitude variation trolley 4 passes through support
Behind rope device position, rope supporting device restores support rope form state.
As a preferred embodiment, the rope supporting device in the present embodiment has several sets, when 1 amplitude of boom of crane
When very long, several set present apparatus are installed on boom 1, can effectively reduce the sagging height of hoist rope 2, and this dress
