For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment
The embodiment of the present invention provides a kind of hydraulic bolt elevating system bolt device, and this bolt device goes for hydraulic bolt cellular type elevating system, is specifically arranged on the hydraulic lifting mechanism or wedge bracket of lowering or hoisting gear, and referring to Fig. 1～4, this device comprises:
Latch 1, hydraulic spring grease cup cylinder 2, threeway directional control valve 3, relief valve 4, oil hydraulic pump 5, fuel tank 6 and be used to this oil hydraulic pump 5 that the oil hydraulic motor 7 of power is provided, latch 1 is arranged on the telescopic end of hydraulic spring grease cup cylinder 2, the filler opening of oil hydraulic pump 5 is connected with the filler opening of fuel tank 6 and threeway directional control valve 3 respectively with oil outlet, the oil outlet of threeway directional control valve 3 is connected with hydraulic spring grease cup cylinder 2 and fuel tank 6 respectively with return opening, the filler opening of relief valve 4 is connected on the hydraulic circuit between threeway directional control valve 3 and oil hydraulic pump 5, and the oil outlet of relief valve 4 is connected with fuel tank 6.
Particularly, referring to Fig. 1, above-mentioned threeway directional control valve 3 can arrange two valve position, during right valve position, the filler opening of threeway directional control valve 3 is closed, hydraulic oil cannot enter by the filler opening of threeway directional control valve 3 hydraulic spring grease cup cylinder 2, simultaneously, the return opening of threeway directional control valve 3 is opened, hydraulic oil in hydraulic spring grease cup cylinder 2 flows back to oil cylinder 6 by the return opening of threeway directional control valve 3, spring in hydraulic spring grease cup cylinder 2 recovers, promoting latch 1 extends, thereby withstand spud leg 10, and the hydraulic oil that oil hydraulic pump 5 oil outlets flow out cannot be by threeway directional control valve 3, can only flow back to oil cylinder 6 by relief valve 4, now oil hydraulic motor 7 is in low load condition, as shown in Figure 2.When latch 1 rises or drops to the position of hinge last, can insert the hinge last of spud leg 10, as Fig. 3.During left valve position, the filler opening of threeway directional control valve 3 is opened, hydraulic oil enters hydraulic spring grease cup cylinder 2 through the filler opening of threeway directional control valve 3 under the effect of oil hydraulic pump 5, and the pressure that hydraulic oil produces shortens the spring in hydraulic spring grease cup cylinder 2, thereby drives latch 1 to retract, thereby can make latch 1 extract, now oil hydraulic motor 7 is in high load condition, as shown in Figure 4, and when latch 1 rises or declines after a segment distance, can fuel cut-off, make latch 1 again withstand spud leg 10.Therefore, the bolt device that the present embodiment provides only need to be when extracting hinge last, to hydraulic spring grease cup cylinder 1 carry out fuel feeding be oil hydraulic motor 7 in high load condition, reduced energy consumption, also reduced the generation of heat simultaneously, guaranteed safety.
Particularly, hydraulic spring grease cup cylinder 2 comprises: cylinder body 21, be arranged on the piston 22 in cylinder body 21, piston rod 23 and the spring 24 that one end is connected with piston 22, piston rod 22 and spring 24 are separately positioned on the both sides of piston 22, and latch 1 is arranged on piston rod 22 front ends.Wherein, piston rod 22 is arranged on the left side of piston 22, and spring 24 is arranged on the right of piston.
As shown in Figure 1, in the present embodiment, this spring 24 can be metal spring.In a further embodiment, this spring 24 can also be pneumatic spring.
Further, this device also comprises: one-way valve 8, this one-way valve 8 is arranged on the hydraulic circuit between the oil outlet of oil hydraulic pump 5 and the filler opening of threeway directional control valve 3, and this one-way valve 8 is also between the filler opening in relief valve 4 and the filler opening of threeway directional control valve 3 simultaneously.At threeway directional control valve 3 during in left valve position, oil hydraulic pump 5 is hydraulic spring grease cup cylinder 2 fuel feeding, now latch 1 is in retracted mode, if now latch 1 is subject to mechanical shock, can the hydraulic oil in hydraulic spring grease cup cylinder 2 be produced and be impacted, this impacts can be along with hydraulic circuit transmission, oil hydraulic pump 5 and whole hydraulic circuit are exerted an influence, but the existence due to one-way valve 8, this impact force can be truncated at one-way valve place, thereby can, when latch 1 is subject to mechanical shock, slow down the impact of mechanical shock on hydraulic circuit.
Further, threeway directional control valve 3 can be electromagnetic three-way directional control valve.
As shown in Figure 3, electromagnetic three-way directional control valve 3 comprises directional control valve body 31 and valve body 32, directional control valve body 31 is provided with oil inlet P, oil outlet C and oil return inlet T, and valve body 32 is for selecting oil inlet P and oil return inlet T one in opening state, and another is in closed condition.
Wherein, valve body 32 comprises electromagnetic coil 321 and is provided with the iron block 322 of through hole, and iron block 322 moves under the effect of electromagnetic coil 321, so that in through-hole alignment oil inlet P and oil return inlet T one.
Further, this relief valve 4 can be electromagnetic relief valve.When threeway directional control valve is during in left valve position, electromagnetic relief valve is in high pressure conditions, and hydraulic oil can not flow back to fuel tank from relief valve, and when threeway directional control valve is during in right valve position, electromagnetic relief valve is in low-pressure state, and hydraulic oil cannot enter threeway directional control valve, can only flow back to fuel tank from relief valve.
Further, this device also comprises the radiator 9 being arranged on fuel tank 6.Because, the device that the embodiment of the present invention provides does not need always to hydraulic spring grease cup oil supply cylinder, the heat that whole device is produced is few, therefore can suitably reduce the power of used radiator, has saved cost.
The embodiment of the present invention is by latch being arranged on to the telescopic end of hydraulic spring grease cup cylinder, and when latch does not insert hinge last, latch, under the effect of hydraulic spring grease cup cylinder medi-spring, withstands spud leg, when latch rises or drops to hinge last place, inserts hinge last; And when needs are extracted hinge last by latch, adopt oil hydraulic motor and oil hydraulic pump to hydraulic spring grease cup oil supply cylinder, hydraulic spring grease cup cylinder medi-spring is shortened, thereby drive latch to extract hinge last, and rise or decline after a segment distance at latch, can stop to hydraulic spring grease cup oil supply cylinder, spring recovers length, latch withstands spud leg again, and now hydraulic oil flows back to oil cylinder by relief valve.Therefore, this bolt device is inserting, is extracting in the process of hinge last, only need to be to hydraulic spring grease cup oil supply cylinder within very short time, and now oil hydraulic motor is just in high load condition; And in other times, hydraulic oil circulates by relief valve, oil hydraulic motor is always in low load.So this bolt device can be avoided in prior art the oil hydraulic motor shortcoming in high load condition for a long time, has saved energy, has guaranteed safety.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
