Abstract
The utility model relates to a light removable crane which mainly solves the problem that the original crane base is not removable. The crane base of the utility model comprises a cross beam and two longitudinal beams; the cross beam and two longitudinal beams are connected in a plugging mode or a clamping mode, and are fixed by screw bolts; the two longitudinal beams and the intermediate cross beam are connected in the plugging mode or the clamping mode, and are fixed by the screw bolts. Thus, the utility model is convenient for packaging, transportation or storing; otherwise, the crane fixes the jack base, effectively preventing the jack from swinging when working to be convenient for installation and use.
Description
The utility model relates to a kind of hoisting crane.
The workshop that U.S.'s Olympic industrial provides is a kind of hoisting crane of being made up of base, column, jack, arm, suspension hook, cardan wheel with portable hoisting crane and engine hoist machine product.Its weak point is that the longeron, crossbeam and the intermediate transverse girder that constitute base are welded into an integral body, and floor area is very big, and is relatively more difficult to packing, the transportation of product.The still interim product that uses of this product is deposited when not required and is all compared difficulty.The jack base of this product is unfixing in addition, makes arm produce swing easily, and hoisting crane is damaged.
The purpose of this utility model is to overcome on the basis of above-mentioned deficiency, and a kind of hoisting crane base easy accessibility is provided, be convenient to pack, transport, deposit, and the fixing a kind of removable portable hoisting crane of jack base.
The utility model is achieved in that it comprises the column (4) that is fixed on this hoisting crane base, the hinged arm in the upper end of column (4) (5), and the front end hinge axis (11) of arm (5) is gone up the suspension hook (8) that there is the band chain rope in system; Between column (4) and arm (5) jack (6) is installed, the middle part of the upper end of jack (6) and arm (5) is hinged, and the lower end base of jack (6) is positioned on the platform (7) that is fixed on the column (4); Cardan wheel (9) is installed, so that move the position of this hoisting crane on the base of this hoisting crane.The technical essential of this hoisting crane is: form being connected to plug-in mounting or clamping structure and being connected of the crossbeam (2) of this hoisting crane base and two longerons (10), and be fixed with bolt.The plug-in mounting structure of crossbeam (2) and two longerons (10) is: a side of crossbeam (2) is fixed with two boss, two longerons (10) left end centre hole is inserted into respectively on two boss of crossbeam (2), and with bolt that crossbeam (2) and two longerons (10) is fixing as a whole.The structure that clamps of crossbeam (2) and two longerons (10) is: the left end of two longerons (10) fix respectively two "
" the shape draw-in groove, two draw-in grooves on two longerons (10) all are stuck on the crossbeam (2), and with bolt that two longerons (10) and crossbeam (2) is fixing as a whole.The intermediate transverse girder (1) of vertical columns (4) is with two longeron (10) plug-in mountings or clamp structure and be connected, and is fixed with bolt.Intermediate transverse girder (1) with the plug-in mounting structure of two longerons (10) is: the inboard of two longerons (10) is fixed a boss respectively, the two ends centre hole of intermediate transverse girder (1) is inserted into respectively on the inboard boss of two longerons (10), and with bolt two longerons (10) and intermediate transverse girder (1) is fixed as one.The version that clamps between intermediate transverse girder (1) and two longerons (10) is: the two ends of intermediate transverse girder (1) fix respectively one "
" the shape draw-in groove, this draw-in groove is installed on respectively on two longerons (10), and intermediate transverse girder (1) and two longerons (10) is fixed as an integral body with bolt.When moving in order to overcome this hoisting crane, jack (6) is easy to generate the situation of swing, and the base of jack (6) is fixed by bolts on the platform (7) on the column (4), has so just constituted this hoisting crane.
The suspension hook of this hoisting crane (8) ties up on the hinge axis (11) by chain cable, can adopt traditional mode, and promptly chain cable is connected with hinge axis (11) through the right-hand member aperture of arm (5).But this version, chain cable is swung easily.In order to overcome this weak point, can adopt another kind of form, promptly open a groove on the arm (5) under the hinge axis (11), making is that the chain cable of suspension hook (8) passes this groove and ties up on the hinge axis (11), so just can make the chain cable vertical hanging, structure is more reasonable.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is crossbeam (2) and longeron (10) or longeron (10) and intermediate transverse girder (1) plug-in mounting structure enlarged drawing;
Fig. 3 is that crossbeam (2) clamps the structure enlarged drawing with longeron (10) or longeron (10) with intermediate transverse girder (1);
Fig. 4 is the enlarged drawing of the chain cable of suspension hook (8) through arm (5) fluting and hinge axis (11) connection structure.
The utility model has the advantages that: when transporting or depositing, crossbeam (2), intermediate transverse girder (1), longeron (10), column (4), pull bar (3), jack (6) and arm (5) can being taken apart into independently, parts carry out the branch packing or concentrate packing, packing easily, the volume that takes up space is little, is convenient to transport and deposit.
