Abstract
The utility model discloses a folding and moveable crane, comprising a base which is provided with support feet and traveling wheels, a column frame, a boom, and an oil jack or a pressure oil cylinder. The utility model is characterized in that the base is provided with a minor cross beam and two short longitudinal beams, and one end of each of the longitudinal beams is provided with the traveling wheels; one end of the two support feet is respectively hinged with the corresponding short longitudinal beam loosely or arranged on a connecting frame on the longitudinal beam, and the support feet are respectively fixed at the two ends of the minor cross beam by wing bolts.
Description
The utility model is about elevator machinery, particularly about the elevator machinery of movable type.
Elevator machinery portable in the elevator machinery divides rail and trackless two big classes.Personnel selection is tried hard to recommend a kind of cantilever derrick is arranged in the moving Norail Cranes, and its end is hinged on the column support perpendicular to base.The bottom-hinged of oil jack or oil pressure cylinder is on column support or base, and the plunger top of oil jack or oil pressure cylinder then is hinged on the position, force of cantilever.Connect the hook of weight and the other end that lifting chain then is arranged on cantilever.For making things convenient for manpower to carry out, this not establishing of hoisting crane is heavy, only comes balance by the weight of machine own, so the center of gravity of hoisting crane+weight is in and is arranged in the areal of support that several road wheels on the base form must make lifting the time.For this reason, base is provided with two overhanging support foots, is played weight to place between above-mentioned two support foots.Because above-mentioned two support foots are longer, and fixedly install again, therefore when machine shifts the working space, need bigger running space, especially when turning more very.The characteristic that this has just limited its maneuverability hinders it to use in narrow and small place in the aisle.
No matter the purpose of this utility model is to provide a kind of movable crane that needs less running space of keeping straight on or turn.
The purpose of this utility model is achieved in that a kind of collapsible movable crane that comprises the very heavy or oil pressure cylinder of the base, column support, cantilever, the oil pressure that are provided with support foot and road wheel, it is characterized in that: described base is provided with two beam carlines that secondary crossbeam and an end have road wheel; One end of two support foots is hinged on cooresponding beam carline respectively loosely or is arranged on the link span on the beam carline, and is separately fixed at the two ends of secondary crossbeam with the butterfly nut.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of facing of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the mode of operation of the utility model when folding.
Fig. 4 is the partial schematic diagram of the utility model auxiliary.
Referring to Fig. 1 and 2, the utility model comprises base, column support, cantilever, oil pressure is very heavy or oil pressure cylinder 15.Base comprises main beam 11; Secondary crossbeam 8; Beam carline 20 and 25; Road wheel 5,7,10,18,22 and 24; With support foot 6 and 23.Longeron 20 and an end of 25 link with main beam 11 respectively, and their other end is provided with road wheel 22 and 7.Secondary crossbeam 8 connects an end of beam carline 20 and 25 nearly road wheels 22 and 7, and stretches out in outside main beam transverse 20 and 25. Road wheel 10 and 18 is separately positioned on main beam 11 two ends.Support foot 6 and an end of 23 are hinged on beam carline 25 and 20 or be arranged on the link span 9 and 19 on the above-mentioned main beam transverse respectively loosely, and are separately fixed at the two ends of secondary crossbeam 8 with dish- shaped bolt 12 and 21; Their other end is respectively arranged with road wheel 5 and 24.Described hinged loosely being meant when removing butterfly nut 12 and 21, two support foots 6 and 23 can be swung certain angle beta in the plane of its jointed shaft, make support foot 6 and 23 can walk around secondary crossbeam 8(shown in Fig. 2 long and two-short dash line) carry out rotatablely moving around the jointed shaft axial line.Above-mentioned pendulum angle β is not more than 10 °.Column support is made up of main supporting rod 13 and two sub-strut bars 14 and 17.One end of cantilever 1 is hinged on an end of main supporting rod 13, and its other end is provided with telescopic auxiliary 2.The top of auxiliary 2 is provided with lifting chain 3 and hook 4.The cylinder barrel bottom-hinged of the very heavy or oil pressure cylinder 15 of oil pressure on main supporting rod 13, its plunger top be hinged on cantilever 1 the place, force.Above-mentioned force makes angle of rotation α=90～100 ° of cantilever 1 at the allocation position of cantilever 1, and guarantees initial angle alpha
1=20～30 °.Main supporting rod 13 tops are provided with hook 16 and 26(Fig. 3).Hoisting crane is lowered into initial angle α with cantilever 1 earlier when shifting the working space
1The position, again butterfly nut 12 and 21 is removed, the two ends that make two support foots 6 and 23 swing earlier walk around secondary crossbeam 8 rotate up again, until hook 16 and 26 with they hook.At this moment, the center of gravity of entire machine is in the areal of support of being made up of road wheel 7,10,18 and 22; And greatly shortened normal manner, can shift easily and move.Auxiliary 2 is provided with some adjustment holes 27, can carry out the level that has of stretching out normal manner on cantilever 1 by latch and regulate.Auxiliary 2 is that section is the hollow material of rectangle, and its top is provided with one upwards or the opening 28 and the perpendicular narrow slit that communicates 29 of oblique upper.The width of described narrow slit 29 is slightly larger than or equals the diameter of lifting chain 3 chain link section bars, the length that can regulate lifting chain 3 by opening 28 and narrow slit 29.
The utility model is compared with general portable crane and only made little architecture advances, and is therefore simple in structure, and it is convenient to make; But have the characteristics of maneuverability of the transfer work-yard of the unexistent height of general portable crane, thereby enlarged its range of application.
