Abstract

The utility model relates to a hydraulic elevator lifting mechanism. An outer door frame is a fixed on the wall of an elevator shaft; an oil cylinder is fixed at the bottom of the outer door frame; a piston rod is provided with a sprocket shaft with a sprocket at either end; the inside of the outer door frame is provided with more than two inner door frames which can slide up and down in the outer door frame; the outer door frame is connected with the first inner door frame through a sprocket and a plate type lifting chain; the inner door frames are connected through a sprocket and a plate type lifting chain; and a bench bracket with a bench is connected with the inner door frame at the innermost. When the hydraulic elevator lifting mechanism operates, the oil cylinder is filled with pressure oil; the piston rod extends; the sprockets on the outer door frame pull the plate type lifting chain upwards; the first inner door frame ascends along the outer door frame and pull the second inner door frame to move upwards along the first inner door frame through the sprockets on the first inner door frame and the second inner door frame as well as the plate type lifting chains; in a similar way, the inner door frame at the innermost pushes the bench bracket to ascend; the oil cylinder discharges the pressure oil; the piston rod retracts; and more than two inner door frames and the bench bracket descend. The utility model has the advantages of stable operation, accurate stopping, safety, reliability and high load-bearing capacity.

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aim to provide a kind of operate steadily, stop accurate, safe and reliable, load-carrying capacity is big, be suitable for low building of floor and top and can not install a kind of elevator that is used for hydraulic elevator that the occasion of machine room is used.

The implementation of the utility model purpose is, a kind of elevator that is used for hydraulic elevator, outer mast is fixed on the elevator wall, oil cylinder is fixed on the connecting panel of outer mast bottom, sprocket shaft is housed on the piston rod, sprocket shaft two ends dress sprocket wheel, the plural inner upright mounting that can slide up and down along outer mast is arranged in the outer mast, the inner upright mounting ecto-entad is descending, the sliding up and down along the outside of adjacent the inside, article one, board-like hoisting chain one end is fixed on the otic placode of first inner upright mounting bottom, the other end is fixed on the otic placode of outer mast bottom by first sprocket wheel, 4 side guide wheels and 6 guide wheels that can slide in the outer mast groove are housed on first inner upright mounting, 4 side guide wheels and 4 guide wheels that can slide in the first door frame groove are housed on second inner upright mounting, board-like hoisting chain one end of second is fixed on the otic placode of second inner upright mounting bottom, the other end is fixed on the otic placode of first door frame bottom by second sprocket wheel, load onto plural inner upright mounting and board-like hoisting chain with this, the bench board carriage links to each other with interior inner upright mounting, on the bench board carriage bench board is arranged.

During the utility model work, injection pressure oil in oil cylinder, piston rod protrudes upward, sprocket wheel on the outer mast upwards spurs the board-like hoisting chain of article one, first inner upright mounting is risen along outer mast, because first inner upright mounting rises along outer mast, sprocket wheel on first inner upright mounting upwards spurs the board-like hoisting chain of second, sprocket wheel on second inner upright mounting upwards spurs the 3rd slatted hoisting chain, make the 3rd inner upright mounting along the second inner upright mounting upward movement simultaneously, by that analogy, interior inner upright mounting push work platform carriage and bench board rise; During oil cylinder discharge pressure oil, the piston rod withdrawal, gravity descends plural inner upright mounting, bench board carriage and bench board.

That the utility model operates steadily, stops is accurate, safe and reliable, processing and manufacturing is simple, load-carrying capacity is big, and it is reliable especially to be suitable for requirement, and floor low building, particularly top can not be installed the occasion of machine room and use.

The specific embodiment

Interior to have below, in, the elevator of the hydraulic elevator of outer three door frames describes the utility model in detail.

With reference to Fig. 1,2,3,4,5,6, outer mast 1 usefulness bolt and nut 20 is fixed on the elevator wall 9, having in the outer mast 1 can be along outer mast middle door frame 2 that slides up and down and the inner upright mounting 3 that can slide up and down in middle door frame, oil cylinder 19 is fixed on the connecting panel 23 of outer mast bottom, sprocket shaft 13 is housed on the piston rod 15, sprocket shaft 13 two ends dress sprocket wheel 14, board-like hoisting chain 16 1 ends are fixed on the otic placode 17 of middle door frame 2 bottoms, the other end is fixed on the otic placode 18 of outer mast bottom by sprocket wheel 14, on the middle door frame 4 side guide wheels 8 and 6 guide wheels 7 that can slide are housed in outer mast groove 22,4 side guide wheels 8 and 4 guide wheels 7 that can slide in middle door frame groove 21 are housed on the inner upright mounting, board-like hoisting chain 11 1 ends are fixed on the sprocket shaft 13 at plunger 15 tops, the other end is fixed on the otic placode 12 of inner upright mounting 3 bottoms by sprocket wheel 10, bench board carriage 4 links to each other with inner upright mounting 3 by bolt 5, and bench board 6 is arranged on the bench board carriage 4.

During the utility model work, when injection pressure is oily in oil cylinder 19, piston rod 15 protrudes upward, sprocket wheel 14 on the outer mast upwards spurs the board-like hoisting chain 16 of article one, door frame 2 rises along outer mast 1 in making, because middle door frame 2 rises along outer mast 1, the sprocket wheel 10 on the middle door frame upwards spurs the board-like hoisting chain 11 of second, door frame 2 upward movements in inner upright mounting 3 edges, push work platform carriage 4 and bench board 6 rise simultaneously; During oil cylinder discharge pressure oil, piston rod 15 withdrawals, gravity descends middle door frame 2, inner upright mounting 3, bench board carriage 4 and bench board 3.
