Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The standing auxiliary load-reducing device shown in fig. 1 comprises a bottom plate 300, a seat plate 200 arranged horizontally, and two sets of load-reducing components 100 connecting the bottom plate and the seat plate. The two groups of load reducing assemblies are identical in structure and are symmetrically arranged on two sides of the bottom plate.
As shown in fig. 1 and 2, each set of load descending assemblies includes a
The structure of all the rotary joints is the same. As shown in fig. 3, each rotary joint includes a sleeve 131, a bearing 129, a stepped shaft 130, a spacer 128, and an end cap 127. The middle part of the sleeve is communicated; the outer ring of the bearing is fixed on the inner wall of the sleeve; the stepped shaft is rotatably positioned in the inner ring of the bearing and protrudes outward from one end of the sleeve; the end cover is fixedly covered at the other end of the sleeve through a screw; the gasket is mounted between the end cap and the sleeve. The sleeve, the bearing and the stepped shaft are coaxially arranged.
One end of the first rod piece is hinged with the first rotary joint, and the other end of the first rod piece is hinged with the third rotary joint. One end of the second rod piece is hinged with the second rotary joint, and the other end of the second rod piece is hinged with the fifth rotary joint. The fourth rotary joint and the fifth rotary joint are respectively hinged on two sides of the same end of the connecting rod; the other end of the connecting rod is hinged with the sixth rotary joint. One end of the first push rod is hinged to the first rod (in the figure, an arc-shaped
The first cantilever and the second cantilever are equal in length and are arranged in parallel, so that the connecting rod, the first cantilever, the bottom plate and the second cantilever form a first parallelogram mechanism; the first rod piece and the second rod piece are equal in length and are arranged in parallel, so that the first rod piece, the first cross rod, the second rod piece and the second cross rod form a second parallelogram mechanism.
