Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete detailed description is further done to the present invention.
Embodiment one:
As depicted in figs. 1 and 2, a kind of load balancing mechanism of flexible riser, comprise a carrying bearing 1, equalizer bar 2, two adjusting brackets 3, two and promote tensioning frame 5, two tension wheels 13 and two flexible-belts 6, described carrying bearing 1 is hinged at the middle part of equalizer bar 2 with equalizer bar 2, two adjusting brackets 3 are hinged with the two ends of equalizer bar 2 respectively, and the hinge hole center at equalizer bar 2 two ends is equal to the distance at hinge hole center, middle part.Particularly, described carrying bearing 1 is welded by three blocks of plates, and in ∏ shape, described equalizer bar 2 is in tabular, and the middle part of equalizer bar 2 is inserted between two risers of ∏ shape carrying bearing 1, then uses a jointed shaft to connect.Described adjusting bracket 3 is also welded by three blocks of plates, and in the shape of falling ∏, the two ends of equalizer bar 2 are inserted between two risers of two shape of falling ∏ adjusting brackets 3 respectively, and uses a jointed shaft to connect separately.
Described lifting tensioning frame is welded by three blocks of plates, in ∏ shape, two promote tensioning frame and are connected with two adjusting brackets 3 respectively by adjustment bolt, particularly, the two ends of described adjustment bolt are respectively by nut and adjusting bracket 3 and promote tensioning frame and fix, in the present embodiment, the flange end of adjustment bolt 4 is fixedly connected with the horizontal plate of adjusting bracket 3 by a nut, the free end of bolt is fixed by two nuts and the horizontal plate promoting tensioning frame 5, and described two nuts are separately positioned on the both sides promoting tensioning frame 5 horizontal plate.
Described tension wheel 13 is hollow or solid cylindric, and two tension wheels are separately positioned on two ∏ shapes and promote between two risers of tensioning frames.And two tension wheel central axial direction are consistent, one end of two described flexible-belts 6 is fixedly connected with two tension wheels respectively.
Embodiment two:
As shown in Figure 3 and Figure 4, in the present embodiment, described carrying bearing 1 is welded by two boards, T-shaped, the clamp region that described equalizer bar 2 is fixed together for two boards parallel interval, the riser of T-shaped carrying bearing 1 inserts between the two boards of equalizer bar 2, and described adjusting bracket 3 is also welded by two boards, in inverted T-shaped, the riser of two inverted T-shaped link spans inserts between the two boards of equalizer bar 2 respectively.The present embodiment remainder is all roughly the same with embodiment one.
Two kinds of application examples that Fig. 5-Fig. 8 is the detailed description of the invention shown in the embodiment of the present invention one.
In the first application example, as shown in Figure 5, Figure 6, walking in a horizontal state frame 7 is provided with fixed mount 8, carrying bearing 1 of the present invention is fixedly connected with fixed mount 8, link span 11 for being connected with weight 12 is fixed with breast wheel 10, and described breast wheel is two, is fixedly connected with after two soft ribbons walk around a breast wheel respectively with the winding actuating device 9 be arranged on walking in a horizontal state frame 7, thus winding actuating device 9 drives soft ribbons 6 to be elevated, weight 12 is driven to be elevated.
Flexible device used in above embodiment is the soft ribbons of platypelloid type, in practical application, also can use columniform tightrope, or the flexible device of other shape.Use front or in using when finding that each band (rope) stroke under loaded state is not quite identical, adjust the degree of tightness of respective side soft ribbons by adjustment bolt 4, thus make biobelt (rope) carrying even, to ensure the safety performance of bont.
The second application example, as shown in Figure 7, Figure 8, compared with the first application example, eliminate fixed mount and breast wheel, carrying bearing 1 of the present invention is directly fixed on link span 11, the other end of soft ribbons 6 is directly fixedly connected with winding actuating device 9, drives soft ribbons by winding actuating device 9, drives link span 11 and weight 12 to be elevated.
Detailed description of the invention described in the embodiment of the present invention two identical with the application process of the detailed description of the invention described in embodiment one, repeats no more herein.
When two bands (rope) occur that load is uneven, the band (rope) that then stand under load is larger drives the hinged center of equalizer bar 2 coupling end in the middle part of equalizer bar 2 to rotate to this stand under load direction, thus make the hinged center rotating Vortex of another coupling end of equalizer bar 2 in the middle part of equalizer bar 2, the band (rope) making carrying less extends tension, until the identical rear stop motion of two band (rope) stands under load, thus reach the object of all carrying.Adjust the degree of tightness of respective side soft ribbons by adjustment bolt 4, thus ensure that equalizer bar 2 is level under the state do not used.
It should be noted that, the present embodiment and application example are all that it is not construed as limiting the invention in order to clearly the present invention is described.
