Abstract
The utility model discloses a stepped hydraulic elevating mechanism which is composed of an upper stander and a lower stander and is characterized in that two parallel left upright posts are fixed on the lower stander, and two right upright posts are connected on the lower stander; each upright post is provided with an upper anchor ear slide block and a lower anchor ear slide block, and the anchor ear slide blocks are provided with locking devices; an upper transverse lever is fixed between the two upper anchor ear slide blocks of the two left upright posts, a lower transverse lever is fixed between the two lower anchor ear slide blocks, and the upper transverse lever is parallel to the lower transverse lever; another upper transverse lever is fixed between the two upper anchor ear slide blocks of the two right upright posts, another lower transverse lever is fixed between the two lower anchor ear slide blocks, and the upper transverse lever is parallel to the lower transverse lever; oil cylinders are arranged between the two groups of upper and lower transverse levers; the standers are arranged between the two upper transverse levers. The stepped hydraulic elevating mechanism has the beneficial effects that when the oil cylinders have shorter travel route, the upper stander can be near the lower stander; when the upright posts are high enough, the upper standers can also rise highly without being limited by the travel route of the oil cylinder; the plane of the upper stander can be both horizontal and inclined to provide convenience for adjusting the angle of the executive component of the equipment.
Description
Technical field
The utility model relates to a kind of hydraulic mechanical lifting mechanism, especially stepping type hydraulic lifting mechanism.Utilize this mechanism, can be with object up-down to required height, or as the support component of equipment, execution unit lifting to the required height of equipment is organized work.
Background technology
Present hydraulic hoist if realize higher hoisting depth, adopts the double-cylinder type structure usually, or parallelogram formula (also claiming scissor-type) frame.The former utilizes multistage cover cylinder to promote, and the The latter oil cylinder promotes the folding and unfolding of parallelogram framework, can realize mechanism's flat-bed lifting.But these two kinds of structures are more complicated all, and hoisting depth is subjected to the restriction of oil cylinder stroke, and upper spider can not be very low with respect to the height of lower bearing bracket.
Summary of the invention
For overcoming the defective of prior art, the utility model provides a kind of stepping type hydraulic lifting mechanism simple in structure, and its hoisting depth is not subjected to the restriction of oil cylinder stroke, and upper spider can be very low with respect to the height of lower bearing bracket.
The technical scheme that its technical matters that solves the utility model adopts is: lifting mechanism comprises lower bearing bracket, and two parallel left columns are fixed on the lower bearing bracket, and two right columns are connected on the lower bearing bracket, and last anchor ear slide block and following anchor ear slide block are arranged on every root post; On the anchor ear slide block latching device is arranged, be used for anchor ear slide block and column being held tightly and being unclamped; Go up between the anchor ear slide block for two of left column and be fixed with cross tube, be fixed with sheer pole between two following anchor ear slide blocks, upper and lower cross bar is parallel; Right column is fixed with upper and lower cross bar in an identical manner; Be connected with oil cylinder between two groups of upper and lower cross bars; Two cross tube structure of an essay are provided with the upper spider that is used for loaded object.
Its mode of operation is: following anchor ear slide block is locked on column, and sheer pole also maintains static, and last anchor ear slide block unclamps, cross tube is in free state, by the operation hydraulic efficiency pressure system, the oil cylinder piston bar is stretched out, be that the upper and lower hinged distance of oil cylinder strengthens, the cross tube segment distance that rises; Then, last anchor ear slide block is locked on column, and following anchor ear slide block unclamps, and by the operation hydraulic efficiency pressure system, makes oil cylinder piston bar withdrawal, and promptly the distance of oil cylinder upper and lower end reduces, the sheer pole segment distance that rises.Like this, just finished a stepping uphill process.If upper spider will continue to rise, then continue to carry out the stepping uphill process; If upper spider decline, then with reference to stepping uphill process reverse operating.Adopt articulated manner as right column and lower bearing bracket,, upper spider is tilted then by the different step distance of control left and right sides oil cylinder.
Its beneficial effect is: when oil cylinder stroke hour, upper spider can be very low from lower bearing bracket, if column is enough high, then upper spider 7 also can rise very highly, not limited by oil cylinder stroke.Be that nadir is restricted little and range is big.The upper spider plane can also tiltable of level, adjusts angle for the execution unit of equipment and provides convenience.
Description of drawings
Fig. 1 is a front schematic view of the present utility model;
Fig. 2 is the left side scheme drawing of Fig. 1.
Among the figure: 1, lower bearing bracket, 2, left column, 3, sheer pole, 4, hinged under the oil cylinder, 5, oil cylinder, 6, hinged on the oil cylinder, 7, upper spider, 8, cross tube, 9, right column, 10, go up the anchor ear slide block, 11, handle, 12, anchor ear slide block down, 13, right column is hinged.
The specific embodiment
Specify embodiment of the present utility model below in conjunction with accompanying drawing.
Operating process is: following anchor ear slide block 12 is locked on column, sheer pole 3 also maintains static, last anchor ear slide block 10 unclamps, cross tube 8 is in free state, by the operation hydraulic efficiency pressure system, oil cylinder 5 piston rods are stretched out, promptly upper cylinder hinged 6 strengthens with the distance of following oil cylinder hinged 4, cross tube 8 risings one segment distance, then, last anchor ear slide block 10 is locked on column, and following anchor ear slide block 12 unclamps, by the operation hydraulic efficiency pressure system, make the withdrawal of oil cylinder 5 piston rods, promptly upper cylinder hinged 6 reduces with the distance of following oil cylinder hinged 4, sheer pole 3 risings one segment distance, like this, just finished a stepping uphill process; If upper spider 7 will continue to rise, then continue to carry out the stepping uphill process.If upper spider 7 declines, then with reference to stepping uphill process reverse operating.
If upper spider 7 is tilted, then make different the getting final product of distance of right left oil cylinder stepping.
In order to increase the hoisting force of lifting mechanism, can take to increase the mode of oil cylinder.Each more than oil cylinder promptly.
