In fig. 1, 2 and 3, 1, a base is installed; 2. a lifting platform; 3. a hydraulic oil cylinder support; 4. a guide upright post; 5. a hydraulic cylinder; 6. a hinged seat of the lifting platform; 7. a lower hinge base of the oil cylinder; 8. a guide slider; 9. a hinged seat is fixed on the oil cylinder; 10. a transverse upright post fixing plate; 11. and (5) fixing plates of the longitudinal upright posts.

(V) specific embodiment:

the utility model discloses a two most of frame supporting component and two-stage hydraulic lifting subassembly, the frame supporting component includes 8 guide post (4), every 4 divide into a set ofly, total 2 groups, divide and arrange the both ends of installation base (1) in, 8 guide post (4) are through bolt fixed mounting on installation base (1), through two horizontal stand fixed plate (10) and 2 vertical stand fixed plate (11) fixed connection on the top of every 4 guide post (4), the frame supporting component provides reliable and stable support for whole hydraulic lifting platform.

The two-stage hydraulic lifting assembly comprises 4 groups of hydraulic lifting assemblies which are respectively arranged at 4 corresponding positions of the frame supporting assembly, each group of two-stage hydraulic lifting assembly comprises 3 hydraulic oil cylinders (5), the top ends of the hydraulic oil cylinders are jointly hinged to a fixed hinged seat (9) on each oil cylinder, two ends of each fixed hinged seat (9) on each oil cylinder are respectively provided with a guide sliding block (8), and each guide sliding block (8) is arranged on a guide upright post (4) and can freely slide up and down on the guide upright post (4). The lower ends of the two hydraulic oil cylinders (5) on the two sides are hinged to an oil cylinder lower hinged seat (7), the oil cylinder lower hinged seat (7) is fixedly arranged on the hydraulic oil cylinder support (3), and the hydraulic oil cylinder support (3) is fixedly arranged on the mounting base (1), so that the secondary lifting of the platform is realized; the lower end of a middle hydraulic oil cylinder (5) is hinged on a lifting platform hinging seat (6), the lifting platform hinging seat (6) is fixedly connected with a lifting platform (2), and two guide holes in the lifting platform (2) penetrate through two guide upright columns (4), so that the platform is lifted at one stage.

The stroke of the existing lifting platform is 1000mm, two stages of lifting are required to be carried out successively, and the stroke of each stage is 500 mm. Before the lifting platform starts to work, the lifting platform (2) is at the lowest end position (0mm stroke position), and the first-stage lifting oil cylinder, namely the middle single hydraulic oil cylinder (5), is also at the maximum stroke position. The equipment begins to work, do not move on the hydro-cylinder between articulated seat (7) under two hydraulic cylinder (5) fixed connection on the hydro-cylinder on fixed articulated seat (9) and the hydro-cylinder on both sides, play the fixed stay effect, single one-level lift hydraulic cylinder (5) of centre upwards shrink, hydraulic cylinder (5) also move in the middle of 3 of other relevant positions departments are synchronous, drive lift platform (2) upwards promote along guide pillar (4), reach 500mm stroke department when single one-level lift hydraulic cylinder (5), equipment stops the action immediately, wait for a moment, wait for single middle one-level lift hydraulic cylinder (5) synchronous shrink of 4 relevant positions to target in place, the flow that begins to carry out the second grade lift. At the moment, two secondary lifting hydraulic oil cylinders (5) on two sides begin to perform upward lifting action, the primary lifting hydraulic oil cylinder (5) is connected with the lifting platform (2) into a whole and is fixed, a fixed hinged seat (9) on the pushing oil cylinder moves upwards, two guide sliding blocks (8) installed on a guide upright post (4) are driven to slide upwards synchronously along the guide upright post (4), so that the lifting platform (2) connected to the fixed hinged seat (9) on the oil cylinder is driven to continue to move upwards, when the two secondary lifting hydraulic oil cylinders (5) on two sides reach a stroke position of 500mm, the secondary hydraulic lifting components on corresponding positions of other 3 positions stop to act synchronously, and therefore the lifting platform (2) can reach a set stroke through a two-stage lifting process.

When the lifting platform (2) needs to be lowered, the lifting process is opposite to the lifting process of equipment, two secondary lifting hydraulic oil cylinders (5) on two sides firstly contract downwards to drive the lifting platform (2) to descend to 500mm, a single hydraulic oil cylinder (5) in the middle stretches out downwards to push the lifting platform (2) to continuously descend for 500mm after waiting for a moment, and the lifting platform (2) is pushed to continue to descend for 500mm

The existing equipment reaches a set stroke through a two-stage descending process.
