Abstract

The invention discloses a novel linear lifting mechanism for realizing a vertical motion. The mechanism comprises a cylinder mechanism and a connecting rod mechanism; the cylinder mechanism includes a cylinder body, a piston rod and a slide block; the front end of the cylinder body is connected with one end of the piston rod; the other end of the piston rod is connected with a slide block rotating pair; the slide block is embedded in a rocking rod 1, and slides along the rocking rod 1; the connecting rod mechanism includes a rocking rod and a connecting rod; one ends of the rocking rod 1 and a rocking rod 2 are both connected with a second hinge base rotating pair; one end of a rocking rod 3 is connected with a third hinge base rotating pair; two ends of a connecting rod 4 are respectively connected with rocking rod 1 and rocking rod 3 rotating pairs; two ends of a connecting rod 5 are respectively connected with rocking rod 2 and rocking rod 3 rotating pairs; one end of a connecting rod 6 is connected with the rocking rod 2 and the connecting rod 5 through rotating pairs, and the other end is connected with a connecting rod 7 rotating pair; and one end of a connecting rod 7 is connected with the rocking rod 1 and the connecting rod 6 through rotating pairs, and the other end is connected with a connecting rod 6 rotating pair. The novel linear lifting mechanism is excellent in transmission performance, stable in motion and convenient for maintenance, and relatively reduces the cost.

Description

technical field [0001] The invention relates to a linear lifting device without a guide rail, in particular to a linear lifting mechanism. Background technique [0002] As a kind of lifting machinery, the lifting platform is widely used in various workplaces such as logistics, handling, assembly, and offshore oil fields. Its main function is to lift objects to different heights by means of the driving mechanism and the lifting mechanism. [0003] The lifting mechanism can be divided into rigidity and flexibility. The rigid lifting mechanism mainly uses the rigidity of the mechanism to directly lift or push the platform; the existing rigid lifting mechanism mainly uses rack and pinion lifting mechanisms, plunger lifting mechanisms, shears Fork type lifting mechanism, lead screw type lifting mechanism. The flexible lifting mechanism mainly realizes the lifting of the platform by pulling flexible components such as steel wire ropes and chains. In the existing flexible liftin...
