Abstract
The utility model discloses a kind of four post elevator motion compensation mechanisms, comprise four columns arranged in pairs, wherein each side there is a pair, two columns are provided with separately the raising legs that can slide up and down along it, article four, in the space between column, be provided with lifting table, its constructional feature is that the left and right sides of described lifting table is separately near the raising legs of corresponding side, the left side of lifting table is hinged on this side raising legs, the right side of lifting table is hinged with connecting rod, and the other end of connecting rod is hinged on this side raising legs.The utility model stability is strong, operate steadily, can reduce rate of breakdown, improve service life.
Description
Technical field
The utility model relates to a kind of four post elevator motion compensation mechanisms.
Background technology
In auto production line mechanization delivery system, in order to reasonable Arrangement operational path, effectively utilize hall space and conveniently organize production, usually there will be the situation that there is diff-H between identical or different class delivery vehicles.In order to make up this diff-H, usually need to use four post elevators, for vehicle etc. is promoted certain height.Existing four post elevators comprise four columns arranged in pairs, wherein each side there is a pair, two columns are provided with separately the raising legs that can slide up and down along it, article four, in the space between column, be provided with lifting table, the left and right sides of lifting table is all fixed on this side raising legs, four post elevators are also provided with jacking system, for driving the lifting of raising legs.Owing to inevitably there is error in processing and manufacturing, installation process, parallelism between the straightness accuracy of every bar column and each column thereof can not be very desirable, therefore in the process of lifting, interference can be produced between raising legs and column, the card run is caused to pause, will produce transmission device and guiding mechanism like this and impact, have a strong impact on equipment use smoothness, thus affect the service life of four post elevators; Due to the existence of error, in the process of lifting, also likely cause the inclination of lifting table, cause four post elevators to run not steady.
Summary of the invention
The purpose of this utility model is to provide a kind of four post elevator motion compensation mechanisms, to solve the problem.
For achieving the above object, the utility model comprises four columns arranged in pairs, wherein each side there is a pair, two columns are provided with separately the raising legs that can slide up and down along it, article four, in the space between column, be provided with lifting table, its constructional feature be the left and right sides of described lifting table separately near the raising legs of corresponding side, the left side of lifting table is hinged on this side raising legs, the right side of lifting table is hinged with connecting rod, and the other end of connecting rod is hinged on this side raising legs.
Described two column each self-forming side guide rails, described raising legs has two, two raising legss are slidably mounted on the guide rail that a column formed respectively, the left side of lifting table is being hinged near the position at its two ends and raising legs, the right side of lifting table is at the hinged connecting rod respectively of the position near its two ends, and two connecting rods and raising legs are hinged.
Be provided with universal-joint between described lifting table and connecting rod, the two ends of this universal-joint are fixed on lifting table and connecting rod respectively, thus realize this between the two hinged; Be provided with universal-joint between connecting rod and raising legs, this universal-joint two ends be fixed in respectively on connecting rod and raising legs, thus realize this between the two hinged.
Adopt after said structure, can be movable between lifting table and raising legs, connecting rod swing can compensate the range difference between the raising legs of both sides, thus overcomes the card caused because of parallelism equal error between column straightness accuracy and column and pause, and stability is strong; Lifting table can also be made automatically to keep horizontality under the effect of the deadweight of lifting table and carrier thereof, make it operate steadily; Adopt after the utility model, four post elevators can also be made to possess flexible, accurate positioning, characteristic smoothly of transferring, reduce its rate of breakdown, improve its service life.Be connected by universal-joint between lifting table with connecting rod, between connecting rod with raising legs, can compensate the error because column distortion produces, applicability is strong.
In sum, the utility model stability strong, operate steadily, rate of breakdown can be reduced, improve service life.
