Abstract
The utility model discloses a demountable pushing portal frame, and relates to hoisting equipment, in particular to a structure of the portal frame. The demountable pushing portal frame comprises two running wheel brackets, wherein a universal running wheel and a fixed running wheel are connected below each running wheel bracket; at least two vertical columns are connected above each running wheel bracket; the axes of the vertical columns above each running wheel bracket are positioned on the same straight line; two adjacent vertical columns are connected with each other through a flange; the two vertical columns at the uppermost end are hinged with cross beams; the two cross beams are opposite; a lifting lug is connected below each cross beam; and the two cross beams are connected with pin shafts through cross beam connection plates. The pushing portal frame is demountable and can be conveniently carried by a tool vehicle; on the spot, the pushing portal frame is mounted and suspended on the hoisting equipment so as to hoist and carry objects and the height of the pushing portal frame can be adjusted according to the number of the vertical columns, and the span of the pushing portal frame can be adjusted by the cross beam connection plates. The pushing portal frame is convenient to mount, demount and carry; and the height and the span can be flexibly adjusted through hinge shafts and the flanges. Therefore, the working intensity for demounting and mounting a hoist is reduced greatly.
Description
Technical field
The utility model relates to weight-lifting equipment, relates in particular to the structure of portal frame.
Background technology
The dismounting of rolling open and close machine, installation need be carried out lifting or carrying through portal frame; The height-limited system in rolling open and close machine room; The narrow length of passage, many factors such as layout that headstock gear is in one line, and the height of existing portal frame, span are fixed; Can not regulate, bring very big difficulty for dismounting, the installation exercise of headstock gear.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of height, the adjustable reassembling type hand push of span portal frame to be provided.
The purpose of the utility model is achieved in that reassembling type hand push portal frame; Comprise two road wheel supports, the below of each road wheel support connects universal travel wheel and fixing road wheel respectively, and the top of each road wheel support connects at least two root posts; The axis of the column of each road wheel support top is respectively on same straight line; Connect through flange respectively between adjacent two root posts, the column of two the tops is hinged crossbeam respectively, and two crossbeams are provided with in opposite directions; The below of every crossbeam connects hanger respectively, and two crossbeams are connected with bearing pin through cross-beam connecting plate.
The utility model is through above design, and the dismantled and assembled rolling cart of being convenient to carries, and after reaching the spot, assembling is shaped, and hangs up weight-lifting equipment, can carry out hoisting operation, carrying.The rolling open and close machine complete machine is surpassed specified lifting weight, and the big parts that can break are transported after the lifting.The utility model lifting carrying one, hand push is flexible.Height can be regulated through the quantity of column, and span can be regulated through cross-beam connecting plate.Accomplish that dismounting is easy to carry, the height span can be used hinge, the flexible assembly unit of flange.Alleviate the working strength of dismounting, installation rolling open and close machine greatly.
