The specific embodiment
With reference to accompanying drawing 1~2, present embodiment is an example with the hanging apparatus of a military general maintenance car, and it lifts by crane maximum rack is design objective, and sling height is that 1478mm, amplitude are that 1357mm, hoisting capacity are 400kg; Primary member all adopts the Q345 steel plate to be welded into box, and intensity and stability are all good like this, and weight is the lightest.The fixed mount of this device (6) is made up of 4 castors (7) of base plate, door-shaped frame and bolt together, in order to support whole hanging apparatus, and can in the compartment, move easily with ground, with reference to accompanying drawing 6, its middle part of the handle of the connecting rod mechanism of this device (14) is hinged on that fixed mount (6) is gone up, its lower end and two rod hinge connections, the other end of connecting rod is hinged with slide plate (5,8) respectively, on the crossbeam that left and right sides slide plate sky is enclosed within and fixed mount (6) is affixed, this two slide plate can slide on this crossbeam.In the compartment during operation, but control link mechanism symmetry open left and right sides slide plate and be inserted on the bearing pin that welding is good on the floor compartment, hanging apparatus is locked.The aforementioned link mechanism of present embodiment be arranged in front truckle the inboard, can utilize handle (14), referring to Fig. 7, promote a cover leverage and make left and right slide plate (5,8) outwards open 32mm, be inserted on the bearing pin that welding is good on the floor compartment, hoisting mechanism is locked.Oppositely pulling handle (14) moves inward left and right sides slide plate, and the hoisting mechanism release is with regard to the mobile crane assembling device.
The A-pillar of this hanging apparatus (9) is a door-shaped frame, and the bottom connects two rollers with bearing pin, A-pillar can be supported on the ground roll, its lower middle portion not and furcated mechanism (11) and fork (10) hinged.Also correspondingly on the A-pillar (9) be provided with flute profile race (7 ) with column (12), in case the roller of furcated mechanism (7 ") can roll therein.With reference to accompanying drawing 7, development mechanism (2) is the screw mechanism that is driven by bevel-gear sett, and its initiative taper gear mechanism is connected by a flat key with oil motor (15), and oil motor (15) bolt together is on fixed mount (6); Driven wheel of differential is connected with flat key with leading screw (17), and with spacer and nut with the gear axial location, the two ends of leading screw (17) are bearing on the fixed mount (6) with bearing; Nut sleeve is on screw mandrel and affixed with the connecting rod of furcated mechanism (11).Above-mentioned screw mechanism changes the circular movement of screw mandrel into the straight-line motion of nut, drive furcated mechanism (11) horizontal development, two connecting rod middle parts of furcated mechanism (11) are hinged, wherein, the lower end of a connecting rod and fixed mount (6) are hinged, upper end and A-pillar (9) sliding block joint; End also is provided with roller (7 ") on this connecting rod, can slide in the race (7 ) of A-pillar (9); The lower end of another root connecting rod and A-pillar (9) are hinged, upper end and fixed mount (6) sliding block joint, and end also is provided with roller, can rolls in the groove of fixed mount (6) on this connecting rod; The upper end of this root connecting rod also with above-mentioned development mechanism in nut (18) be fixed together, leading screw in the development mechanism (17) dextrorotation drives nut (18) and moves downward, furcated mechanism (11) launches to the right, thereby promotion A-pillar (9), fork (10) move forward together with the rack that is lifted by crane, and rack can be stretched out outside the compartment.
Referring to accompanying drawing 7; development mechanism oil motor (15) or wind (16) drive bevel-gear sett; wherein driven wheel of differential and leading screw (17) are connected; the rotation drive of leading screw and the nut (18) that furcated mechanism connects together are done up and down, and straight-line motion, furcated mechanism movable end are provided with roller; roller moves in the groove of fixed mount (6) and A-pillar (9); pulling force in the time of can bearing the furcated mechanism expansion; can amplitude crooked, that furcated mechanism launches not be advisable so that weight can be released outside the compartment with the protection leading screw, the amplitude that furcated mechanism launches in the present embodiment is 740mm.The structure of winch (1) is with reference to accompanying drawing 8, the winch shell is fixed on the fixed mount (6), winch oil motor (19) links to each other with shell, its output shaft and big gear wheel are coupling, big gear wheel links to each other by the miniature gears of lamella clutch with coaxial overhead cover, drive reel (21) through double reduction again, reel (21) is gone up lay winding wire ropes (22), and the other end of steel rope (22) is connected with the movable end of fork (10).After weight is pushed out outside the compartment, handle winch, loosen the steel rope of fork head, fork rotates around the bearing pin of its underpart, and rack is put to ground, finishes that rack is winched to ground-surface work in the compartment.Accompanying drawing 3~5 these processes of expression.When need in ground winches to the compartment time, are locked in rack on the floor compartment with hoisting mechanism earlier, next launches furcated mechanism (11), loosen the steel rope of fork (10) head, fork is extended outside the car, and the rack of slinging shrinks steel rope, rack is winched to height of wagon, draw furcated mechanism (11) in, be about to rack and hang in the compartment, when the needs hoisting mechanism is carried object on the ground, to preset ground lifting appliance (13) and be filled to fixed mount (6) and go up and to get final product, please refer to accompanying drawing 2.
The lifting of weight is rotated around its underpart bearing pin by winch folding and unfolding rope belt movable pendulum bar (10) and is finished, with reference to accompanying drawing 8, winch oil motor (19) or elevator handle (20) are through deceleration rear drive reel (21) folding and unfolding steel rope (22), the end of steel rope links to each other with fork, drive fork (10) and rotate, finish the lifting operation of weight.
When not having the electricity supply, can utilize wind, manually finish above whole action.
