Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises turn on sensor 1, performs sensor 2, closure sensor 3, lifting tablet 4, tipping bucket cylinder 5, tipping bucket cylinder displacement transducer 6, tipping bucket cylinder displacement tablet 7, vehicle frame 8, swing arm cylinder 9, equipment 10, control box 11, pilot valve 12, distributing valve 13, guide's hydraulic pump 14, working solution press pump 15 and oil sources;
Wherein: turn on sensor 1 is responsible for opening lifting translation automatic regulation function, perform sensor 2 to be responsible for starting to perform lifting translation automatic regulation function, closure sensor 3 is responsible for closing lifting translation automatic regulation function and performing lifting limit function, and their staggered installations on carriage 8;
Lifting tablet 4 adopts annular three contact structures, and its structure center of circle is concentric with swing arm vehicle frame hinge, is arranged on the swing arm of equipment 10, along with swing arm moving arm vehicle frame hinge rotates; In moved arm lifting process, three contact positions of lifting tablet 4 and above-mentioned three sensor one_to_one corresponding, can trigger turn on sensor 1, execution sensor 2 and closure sensor 3 respectively and issue a signal to control box 11;
Tipping bucket cylinder displacement transducer 6 is arranged on the cylinder barrel of tipping bucket cylinder 4; Tipping bucket cylinder displacement tablet 7 adopts stripe board structure, is arranged on the piston rod of tipping bucket cylinder 4; When tipping bucket cylinder 4 moves to certain stroke, tipping bucket cylinder displacement tablet 7 can trigger tipping bucket cylinder displacement transducer 6 and issue a signal to control box 11;
Oil sources is connected with pilot valve 12, distributing valve 13 respectively by working solution press pump 15, and distributing valve 13 oil outlet end is connected with tipping bucket cylinder 5 and swing arm cylinder 9 respectively, and oil sources is connected with pilot valve 12 by guide's hydraulic pump 14, and pilot valve 12 oil outlet end is connected with distributing valve 13.The output of control box 11 connects pilot valve 12, can control electromagnet energising and the power-off of swing arm connection in pilot valve 12 and tipping bucket connection, thus controls stretching of tipping bucket cylinder 5 and swing arm cylinder 9 by distributing valve 13, guide's hydraulic pump 14 and working solution press pump 15.
First the spacing automatic regulation function of lifting of this utility model and lifting limit function are achieved in that, when equipment 10 gives rise to a certain height, the back rake angle of facility changes greatly, the stroke now arranging tipping bucket cylinder 5 makes facility back rake angle identical with ground location, recording now equipment 10 lift height is H, and the stroke of tipping bucket cylinder 5 is L.
When equipment 10 is in the state of ground, lifting tablet 4 triggers turn on sensor 1, and turn on sensor 1 issues a signal to control box 11, and lifting translation automatic regulation function is opened;
When equipment 10 starts lifting, pull back pilot operated handle, loose one's grip to moved arm lifting position, swing arm connection electromagnetic actuation in pilot valve 12, pilot valve 12 swing arm connection spool remains on moved arm lifting position, the hydraulic oil of guide's hydraulic pump 14 promotes distributing valve 13 swing arm connection spool to moved arm lifting position, and working solution press pump 15, to swing arm cylinder 9 large chamber fuel feeding, makes moved arm lifting.
When equipment 10 gives rise to height H, the back rake angle of facility exceeds allowed band, lifting tablet 4 triggers and performs sensor 2, perform sensor 2 and issue a signal to control box 11, make the electromagnetic actuation that pilot valve 12 tipping bucket joins, pilot valve 12 tipping bucket connection spool moves on to tipping bucket position, and the hydraulic oil of working solution press pump 15 is to tipping bucket cylinder 5 large chamber fuel feeding, tipping bucket cylinder 5 is shunk, thus regulates the back rake angle of facility.
When tipping bucket cylinder 5 is retracted to setting stroke L, the tipping bucket cylinder displacement tablet 7 be arranged on tipping bucket cylinder 5 triggers tipping bucket cylinder displacement transducer 6 and issues a signal to control box 11, the electromagnet that pilot valve 12 tipping bucket is joined disconnects, pilot valve 12 tipping bucket connection spool gets back to meta, the hydraulic oil of working solution press pump 15 stops to tipping bucket cylinder 5 large chamber fuel feeding, make tipping bucket cylinder 5 stop shrinking, now the back rake angle of facility is adjusted to allowed band.
When equipment 10 gives rise to the spacing setting height of lifting, lifting tablet 4 triggers closure sensor, and closure sensor 3 issues a signal to control box 11, and lifting translation automatic regulation function is closed.Electromagnet power-off simultaneously on pilot valve 12 swing arm connection, pilot valve 12 swing arm connection spool gets back to meta, and the hydraulic oil of guide's hydraulic pump 14 shifts the swing arm of distributing valve 13 connection spool onto meta, and working solution press pump 15 stops to swing arm cylinder 9 fuel feeding, and swing arm stops lifting.
When equipment 10 falls, do not need lifting translation automatic regulation function, now function is in closed condition, performs sensor 2 and does not work.
When equipment 10 drops to ground location, lifting tablet 4 triggers turn on sensor 1, and lifting translation automatic regulation function is opened, in upper once equipment 10 lifting process, carry out translation adjustment.
