Detailed description of the invention
For understanding content of the present invention further, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.
Embodiment 1
Composition graphs 1 and Fig. 3, a kind of of the present embodiment is convenient to the balance crane dismantling lifting nut, is applicable to carry the operating mode being not more than 500KG.Comprise transmission gearbox 11, top cover 12, bob-weight 2, connecting panel, parallelogram rod member 4, motor 51, screw mandrel 52, lifting nut 53, adapter shaft 54 and column 8.Described column 8 is for supporting transmission gearbox 11, the top of this transmission gearbox 11 is provided with top cover 12, and top cover 12 is fixed on transmission gearbox 11, when need dismantle lifting nut 53 by screw, fast top cover 12 can be taken off, remove the restriction of top cover 12 to dismounting lifting nut 53.
The left and right sides of transmission gearbox 11 offers the first guide groove 111 and the second guide groove 112 respectively, relative to the unified structure design offering vertical direction guide groove of tradition, in the present embodiment, the first guide groove 111, second guide groove 112 includes vertical guide groove and horizontal guide groove, vertical guide groove and horizontal guide groove are spliced into inverted "L" shaped groove jointly, the difference of the first guide groove 111, second guide groove 112 be respective horizontal guide groove to offer direction contrary.By the horizontal guide barrel construction design that this is contrary, only need lifting nut 53 wire winding rod 52 half-twist easily during dismounting lifting nut 53, just lifting nut 53 and the adapter shaft 54 that is attached thereto can be made to break away from the restriction of the first guide groove 111 and the second guide groove 112, make it to be separated with transmission gearbox 11, facilitate follow-up lifting nut 53 to screw out from screw mandrel 52, smart structural design.
Described screw mandrel 52 is vertically arranged, and this screw mandrel 52 runs through transmission gearbox 11, is connected bottom it with motor 51, in the hole that top insertion top cover 12 is offered.Screw mandrel 52 is arranged with lifting nut 53, lifting nut 53 left and right sides is connected to adapter shaft 54, this adapter shaft 54 and lifting nut 53 interference fit, screw mandrel 52, lifting nut 53, adapter shaft 54 form the swing type mechanism of whole balance crane jointly, and balance crane relies on this swing type mechanism to complete up-and-down movement.
Adapter shaft 54 inserts in the first guide groove 111 and the second guide groove 112 through after connecting panel respectively, what deserves to be explained is, the present embodiment considers that subdivision lifting nut 53 can cause the driving efficiency of lifting nut 53 impaired, therefore the mode adopting subdivision connecting panel is changed into, be about to originally connect lower plate 31 for holistic connecting panel is split as and is connected upper plate 32, the one end connecting lower plate 31 connects bob-weight 2, and the other end connects parallelogram rod member 4.Connect lower plate 31 and be connected upper plate 32 and be connected together axle 54, and connection lower plate 31, connection upper plate 32 are flexibly connected by adapter plate 33 and bolt of rear end plate 34, be specially: adapter plate 33 offers connecting bore, this connecting bore and connection lower plate 31, connect the connecting bore that upper plate 32 is offered corresponding (namely on adapter plate 33 connecting bore be connected lower plate 31, connect connecting bore on upper plate 32 and offer position and match), bolt of rear end plate 34 inserts in described connecting bore.In addition, consider and connect lower plate 31 and the fiduciary level being connected upper plate 32 assembling, the present embodiment is all provided with adapter plate 33 (referring to Fig. 2) in the left and right sides of adapter shaft 54, and each adapter plate 33 is fixed by 4 bolt of rear end plates 34.By the structure design of the present embodiment, when lifting nut 53 wearing and tearing need be changed, only bolt of rear end plate 34 need be removed, fast lifting nut 53 can be departed from other mechanisms, save the time of dismounting lifting nut 53.
Also it should be noted that, the present embodiment considers that the bob-weight 2, the parallelogram rod member 4 that are connected with connecting panel are heavier, if rely on manpower to lift during dismounting lifting nut 53, large and the waste of manpower of intensity of workers, transmission gearbox 11 has been offered the first fixed orifice 71, second fixed orifice 72 (referring to Fig. 3), and this first fixed orifice 71, second fixed orifice 72 is offered all in pairs in transmission gearbox 11 both sides.Accordingly, described connection lower plate 31 also offers fixed orifice, when connection lower plate 31 rises to assigned address by lifting nut 53 drive, the fixed orifice that this connection lower plate 31 is offered can be concentric with the first fixed orifice 71, second fixed orifice 72.During lifting nut 53 to be removed, by inserting the first fixed link 61, second fixed link 62, connection lower plate 31 is fixed on transmission gearbox 11, and then also secure the bob-weight 2 connected with being connected lower plate 31 and parallelogram rod member 4, save the manpower of dismounting lifting nut 53.
The process that the present embodiment specifically dismantles balance crane lifting nut is:
Step one, motor 51 control screw mandrel 52 and rotate, lifting nut 53 drives on connecting panel and moves, move on synchronous with the bob-weight 2 that connecting panel is connected and parallelogram rod member 4, to connecting, the fixed orifice that lower plate 31 is offered is concentric with the first fixed orifice 71, second fixed orifice 72, insert the first fixed link 61, second fixed link 62, connection lower plate 31 is fixed on transmission gearbox 11, lifts bob-weight 2 and parallelogram rod member 4 without the need to several staff, save manpower.
Step 2, take top cover 12 away, eliminate the restriction of top cover 12 to dismounting lifting nut 53, remove bolt of rear end plate 34, connections upper plate 32 is separated with connection lower plate 31, removes the restriction of connection upper plate 32 pairs of adapter shafts 54.
Step 3, motor 51 control screw mandrel 52 and rotate, and lifting nut 53 moves on continuing, and now only has adapter shaft 54 to move with on lifting nut 53, is positioned at the horizontal guide groove of the first guide groove 111, second guide groove 112 and vertical guide groove intersection to adapter shaft 54.
Step 4, manually by lifting nut 53 wire winding rod 52 half-twist, lifting nut 53 and the adapter shaft 54 that is attached thereto is made to break away from the restriction of the first guide groove 111 and the second guide groove 112, hand steered lifting nut 53, control lifting nut 53 motionless, screw mandrel 52 rotates backward, lifting nut 53 is screwed out, completes the disassembling section of lifting nut 53.
A kind of balance crane and lifting nut method for dismounting being convenient to dismounting lifting nut described in embodiment 1, select the mode of subdivision connecting panel, driving efficiency is unaffected, by the structure design optimized, make the replacing of lifting nut 53 very convenient, improve the work efficiency of balance crane, and the process operation of dismounting balance crane lifting nut 53 is simple, time saving and energy saving, easy to utilize.
Schematically above be described the present invention and embodiment thereof, this description does not have restricted, and also just one of the embodiments of the present invention shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the invention aim, designing the frame mode similar to this technical scheme and embodiment without creationary, all should protection scope of the present invention be belonged to.
