The invention relates to a vertical displacement constant force spring suspension and support. The vertical displacement constant force spring suspension and support comprises a main spring pressing column (1), a frame (2), auxiliary springs (3), a cutter-shaped cam (4), a main spring suspension rod bolt (6), a suspension rod (8), a positioning pin (9), a positioning tooth plate (10) and an ejector rod swing shaft (11). According to the vertical displacement constant force spring suspension and support, when a pipeline and equipment which are constantly suspended and supported are displaced, the suspension rod drives the main spring pressing column to move downwards, the main spring pressing column presses the ejector rod swing shaft to enable the auxiliary springs to be compressed, under the action of the auxiliary springs, the suspension rod keeps stable, and a worker can conveniently read.
