Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is done and specifically describe in detail further.
Embodiment one:
As depicted in figs. 1 and 2, a kind of load balancing mechanism of flexible riser, including 1, balance of a carrying bearing
2, two adjusting brackets of frame 3, two lifting 5, two tensioning wheels 13 of tensioning frame and two flexible-belts 6, described carrying bearing 1 with flat
Weighing apparatus frame 2 is hinged at the middle part of balancing stand 2, and two adjusting brackets 3 are hinged with the two ends of balancing stand 2 respectively, balancing stand 2 two ends
The distance at hinge hole center to middle part hinge hole center is equal.Specifically, described carrying bearing 1 is formed by three pieces of plate welds,
In ∏ shape, described balancing stand 2 is plate-shaped, and the middle part of balancing stand 2 is inserted between two risers that ∏ shape carries bearing 1, then makes
It is attached with a jointed shaft.Described adjusting bracket 3 is also formed by three pieces of plate welds, and in the shape of falling ∏, the two ends of balancing stand 2 are divided
Between two risers of two shape of falling ∏ adjusting brackets 3, and each Cha Ru be attached using a jointed shaft.
Described lifting tensioning frame is formed by three pieces of plate welds, and in ∏ shape, two lifting tensioning frames pass through to adjust spiral shell respectively
Bolt is connected with two adjusting brackets 3, and specifically, the two ends of described adjustment bolt pass through nut and adjusting bracket 3 and lifting respectively
Tight frame phase is fixed, and 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 the horizontal plate phase of two nuts and lifting tensioning frame 5, and described two nuts are separately positioned on and carry
Rise the both sides of tensioning frame 5 horizontal plate.
Described tensioning wheel 13 is hollow or solid cylindric, and two tensioning wheels are separately positioned on two ∏ shapes liftings
Between two risers of tight frame.And two tensioning wheel central axial direction are consistent, one end of described two flexible-belts 6 respectively with
Two tensioning wheels are fixedly connected.
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, described
The clamp region that is fixed together for two boards parallel interval of balancing stand 2, the riser that t shape carries bearing 1 inserts balancing stand 2
Between two boards, described adjusting bracket 3 is also welded by two boards, and in the shape of falling t, the riser of two shape of falling t links is respectively
Between the two boards of insertion balancing stand 2.The present embodiment remainder is all roughly the same with embodiment one.
Fig. 5-Fig. 8 is two kinds of application examples of the specific embodiment shown in the embodiment of the present invention one.
In the first application example, as shown in Figure 5, Figure 6, fixed mount 8, the present invention are provided with walking in a horizontal state frame 7
Carrying bearing 1 be fixedly connected with fixed mount 8, be fixed with breast wheel 10 on for the link 11 that is connected with weight 12,
Described breast wheel is two, and two soft ribbons are driven with the winding being arranged on walking in a horizontal state frame 7 after bypassing a breast wheel respectively
