Description
Technical field
The utility model relates to technical field of engineering machinery, is specifically related to a kind of equalizing bar that flexibly connects fixed sturcture and this flexible connection fixed sturcture is set.
Background technology
In construction machinery and equipment, the transmission of pulling force need rely on the framing member of transmission pulling force such as arm-tie or drag-line to carry out between structure, for guaranteeing balance, arm-tie or drag-line are generally occurring being articulated on various arm heads both sides or other framing members, and different framing members may be because of restrictions such as performance or transportations, and the span that can offer arm-tie or drag-line can create a difference.
Be example with the arm-tie, the both sides that directly connect its span diverse can cause sheet material can be subjected to side direction moment; While also cannot the control linkage angle because variation is not stopped in the position between framing member.Those skilled in the art adopt trapezoidal equalizing bar (be called for short: ladder beam) the isoequilibrium beam overcome this defective for this reason.
As shown in Figure 1, existing trapezoidal equalizing bar links to each other with arm-tie span diverse and that be positioned at both sides, arm-tie is connected on the switching arm-tie 64 by horizontal bearing pin 66, switching arm-tie 64 (is called for short: vertical axes) 65 be connected on the transverse slat 63 or beam 62 of the different spans of reflection, connected transverse slat 63 or beam 62 by oblique arm-tie 61 more at last by vertical bearing pin.
