Described between the first cable saddle wheel apparatus and last cable saddle wheel apparatus middle cable saddle wheel apparatus and the first cable saddle wheel apparatus between in horizontal plane, have middle acute angle angle angle 0 the degree and the described first acute angle angle between; Middle cable saddle wheel apparatus between the first cable saddle wheel apparatus and last the cable saddle wheel apparatus is obliquely installed at facade has the intermediate, inclined angle, and intermediate, inclined angle angle is between 0 degree and described first inclination angles.
Described cable saddle wheel apparatus comprises crossbeam, and the cable saddle wheel is set on the crossbeam; Crossbeam is provided with first bearing and second bearing, and first bearing is connected with the cable saddle longeron, and second bearing connects with the cable saddle longeron.
The height of described first bearing is higher than the height of second bearing.
Be provided with first supporting leg between the described cable saddle longeron and first bearing and/or second bearing.
Be provided with second supporting leg between described cable saddle longeron and the cat head girder.
Main rope of the present invention realizes that horizontal plane turns to, and the component that cable saddle tilts to produce is offset the horizontal force that the main rope level turns to generation, realizes self-balancing, thereby makes the cable saddle wheel be in pure pressured state, greatly reduces the wearing and tearing of tethered system.Three row's cable saddle wheels are simplified structural system before and after the minimum employing, reduce manufacture difficulty and deadweight.

The specific embodiment
As shown in Figure 1, self-balancing arc cable saddle is located on the cat head girder 1, the structure of self-balancing arc cable saddle mainly comprises the longeron 2 that is connected with cat head girder 1, be interval with at least three cable saddle wheel apparatus from low to high at facade on the longeron 2, longeron 2 is stepped in the present embodiment, on the first segment ladder, be provided with the first cable saddle wheel apparatus 3.1, be interval with the second cable saddle wheel apparatus 3.2 on the ladder and the 3rd cable saddle wheel apparatus 3.3 is last cable saddle wheel apparatus at second joint;
As shown in Figure 2, the cable saddle wheel apparatus comprises being connected with longeron 2 highly to be regulated bearing 5.1 and highly regulates bearing 5.2, is connected on highly regulating bearing 5.1 and highly regulating bearing 5.2 crossbeam 3 is set, and crossbeam 3 is provided with cable saddle wheel 6.Cable saddle wheel 6 is provided with main rope guide groove 6.1; Cable saddle wheel 6 is provided with main rope 7.Be provided with second supporting leg 4.2 between cable saddle longeron 2 and the cat head girder 1.
As shown in Figure 1, highly regulate and be provided with first supporting leg 4.1 between bearing 5.1 and the longeron 2.Main rope 7 is walked around the cable saddle wheel apparatus.
In the present embodiment, cable saddle wheel apparatus in the middle of between the first cable saddle wheel apparatus and last cable saddle wheel apparatus, having one at least, be in the present embodiment, be interval with three cable saddle wheel apparatus from low to high at facade on the longeron 2, cable saddle wheel 6 height in three cable saddle wheel apparatus are curved.
As shown in Figure 3, three cable saddle wheel apparatus have in horizontal plane and turn to, promptly the first cable saddle wheel apparatus 3.1 in horizontal plane with longeron 2 vertical settings, the 3rd cable saddle wheel apparatus 3.3 be last cable saddle wheel apparatus and and the first cable saddle wheel apparatus 3.1 between in horizontal plane, have the first acute angle angle theta 1, in horizontal plane, has the angle of the second acute angle angle theta, 2, the second acute angle angle theta 2 less than the first acute angle angle theta 1 between the second cable saddle wheel apparatus 3.2 (cable saddle wheel apparatus promptly) and the first cable saddle wheel apparatus 3.1; Angle theta 1, θ 1 refer to the angle that two cable saddles are taken turns 6 axis.The first acute angle angle theta 1 is 6.6 ° in the present embodiment, and the second acute angle angle theta 2 is 3.3 °.Be that crossbeam 3 is arranged at horizontal plane also camber, corresponding, cable saddle is taken turns also camber arrangement, thereby the horizontal arc of realizing rope turns to.
