Description
The utility model belongs to a kind of lifting, mechanical device is used in traction, relates to a kind of multifunction hydraulic jack.
Jack all has a very important role in item operations such as lifting, dynamo-electric installation, engineering construction, railway breakdown.Common hydraulic jack can be lifted weight in fixing vertical direction.Because jack has only the upper and lower lifting of axial location, and can not rotate, so the weight lifted of desire maintenance jack, must around weight in 360 ° of scopes around the weight inspection, this makes troubles to maintenance.The jack that also has, spindle rod are horizontal by an angle, but heavy thing can not be lifted again in this thousand tops on the vertical direction top, and applicable surface is very narrow.And the common drawback of above two kinds of hydraulic jacks is: to the weight of close proximity to ground, these two kinds of jacks are all inoperative.
The purpose of this utility model is to design a kind of multifunction hydraulic jack, and it both can vertically push up and lift weight, also can twist to rotating obliquely upward or horizontal jack-up weight.Also can utilize two jacks that the weight of close proximity to ground is sling, accomplish the multi-functional machine use.
The purpose of this utility model realizes by following scheme: the multifunction hydraulic jack is made up of base, locating piece, bearing pin, hydraulic actuating cylinder, connector, various functor, radius stay, suspension hook, thrust unit, connecting device, jacking and swivel block etc.Bearing pin is fixed together hydraulic actuating cylinder and base, and the locating piece that can advance or shift out is housed between base and hydraulic actuating cylinder.Locating piece is pushed cylinder bottom, and hydraulic actuating cylinder promptly is fixed on orthogonal position with base, then has identical functions with existing jack.Locating piece is shifted out cylinder bottom, and hydraulic actuating cylinder is promptly in a certain angle with horizontal base, and jack just can twist to rotation.Base can be installed thrust unit by bearing pin, as propelling rod, but installing and connecting apparatus also, as pull bar.Propelling rod can increase the length of hand push part, and is laborsaving in the stroke that promotes weight.The pull bar use that two jacks can be linked together.The piston type pull bar is housed on the hydraulic actuating cylinder, and connector is equipped with on the pull bar top.Connector has external thread buckle, can connect difformity, the functor of same-action not on it.Also be furnished with jacking and swivel block on the connector, can will hold up the weight hand of rotation.
The multifunction hydraulic jack is a kind of novel lifting gear, but it both fixed vertical top lifts heavy thing, also can twist to rotate obliquely upward or laterally the top lift heavy thing, also can make weight rotation direction in 360 ° of scopes by jacking.But its both separate unit use also can be used in combination two jacks.When being used in combination for two, can reduce the jack height, increase lift, and can lift the weight side travel.With the utility model weight that rises also capable of hoisting, to the weight of the close proximity to ground backward shift of can slinging, also can push up the weight of lifting higher position, and can, ground be uneven place use softer in geology.Its function is many, purposes is wide, be the best equipment of lifting, dynamo-electric installation, engineering construction and railway breakdown.
