Abstract
The invention relates to a working bucket leveling mechanism for an overhead working truck, which has a rotary table compensating cylinder, a lower arm compensating cylinder, a lower arm, an upper arm compensating cylinder, a working bucket compensating cylinder, an upper arm, a jointed connecting rod, a first connection rod, a second connecting rod, a working bucket bracket, a third connecting rod and a fourth connecting rod. The leveling mechanism guarantees the angle between the jointed connecting rod and the horizontal plane unchanged by adopting the rotary table compensating cylinder and the lower arm compensating cylinder that have the same performances and parameters. The working bucket compensating cylinder and the upper arm compensating cylinder which have the same performances and parameters work together with a linkage for the connecting part of the upper and the lower arms and a linkage for the working bucket; in the way, an overhead working balanced construction with a telescopic arm is formed, which solves the problems that the deadweight balancing performance of the working bucket is poor, the shake is serious and the stability is poor. The leveling mechanism is a pure hydraulic mechanism, which is not affected by intense electric field or magnetic field during the overhead working and the working bucket can work stably and is always maintained at the horizontality within plus or minus one degree.

Second group oil cylinder is upper arm balancing cylinder 3 (actuating cylinder) and work bucket balancing cylinder 8 (passive oil cylinder), and the performance and the parameter of two oil cylinders are identical.
In system architecture, when upper arm balancing cylinder 3 was full reduced, work bucket balancing cylinder 8 was stretched entirely.
When work bucket balancing cylinder 8 was full reduced, upper arm balancing cylinder 3 was stretched entirely.
Work bucket balancing cylinder 8 and upper arm balancing cylinder 3 are all stretched or (work bucket balancing cylinder 8 and upper arm balancing cylinder 3 extend range or full reduced during to minimum stroke entirely) when full reduced entirely, the triangle Δ MNO that center-point constituted of the triangle Δ HIJ that center-point constituted of the 8th bearing pin, the 9th bearing pin, the tenth bearing pin and the tenth croisillon de joint homocinetique M, the 14 bearing pin N, the 15 bearing pin O is a congruent triangles, be HI and MN, JI and ON correspondent equal, correspondent equal when HJ and MO stretch entirely or be full reduced at work bucket balancing cylinder 8 and upper arm balancing cylinder 3.
First group oil cylinder is set up to transmit by the jointed connecting rod 15 and second group oil cylinder and is got in touch.
In system architecture of the present invention, the quadrangle MNKL that center-point constituted of the quadrangle HIFG that center-point constituted of optional position the 8th bearing pin H, the 9th bearing pin I, the 6th bearing pin F, the 7th bearing pin G and the tenth croisillon de joint homocinetique M, the 14 bearing pin N, the 11 bearing pin K, the 12 bearing pin L be the congruence quadrangle, promptly HI, IF, FG, GH respectively with MN, NK, KL, LM correspondent equal.
Principle of work of the present invention is as follows:
The telescopic drive underarm 13 of underarm fluctuating oil cylinder 12 rises or falls motion.When underarm 13 rose, ∠ ACB increased Δ θ 1, and jointed connecting rod 15 is subjected to the influence of underarm 13 risings should dwindle Δ θ 1 under the situation that underarm balancing cylinder 14 does not stretch with the angle of horizontal surface; But because this moment, turntable balancing cylinder 10 quilts drove elongation Δ t1, underarm balancing cylinder 14 is along with shortening Δ t1, make the angle of jointed connecting rod 15 and horizontal surface under the flexible situation of underarm balancing cylinder 14, should increase Δ θ 1 if underarm 13 is motionless, that is to say that this moment, 14 shortenings of underarm balancing cylinder were cancelled out each other with the effect that underarm 13 rises, cause the jointed connecting rod 15 and the angle of horizontal surface to remain unchanged.In like manner, when underarm 13 descended, the angle of 15 pairs of horizontal surfaces of jointed connecting rod remained unchanged.
The telescopic drive upper arm 4 of upper arm fluctuating oil cylinder 5 rises or falls motion.When upper arm 4 rose, last underarm angle increased Δ θ 2, and that the angle of jointed connecting rod 15 and horizontal surface remains is constant, and then ∠ IFG increases Δ θ 2 (the 9th bearing pin I is on upper arm 4), and the angle of the KL section of upper arm 4 and horizontal surface increase Δ θ 2.Because this moment, upper arm balancing cylinder 3 was by drive shortening Δ t2, ∠ HIJ reduces Δ θ 3, then ∠ HIF reduces Δ θ 3, work bucket balancing cylinder 8 is along with elongation Δ t2, ∠ MNO increases Δ θ 3, then ∠ KNM reduces Δ θ 3, because of initial position quadrangle HIFG and quadrangle MNKL congruence, be ∠ HIF=∠ KNM, ∠ IFG=∠ LKN, when so upper arm 4 rises, guaranteeing that the ∠ HIF of change still equals the ∠ KNM of corresponding change, concern that according to trigonometric function ∠ LKN increases Δ θ 2, also is that upper arm 4 risings cause the LK section of upper arm 4 and the angle increase of horizontal surface to be caused ∠ LKN increase to be offset by 8 elongations of work bucket balancing cylinder, make the KN section of work bucket support 9 and the angle of horizontal surface remain unchanged, thereby guarantee to be installed in work bucket on the work bucket support 9 and the angle of horizontal surface remains unchanged.In like manner, when upper arm 4 descended, the work bucket also remained unchanged with the angle of horizontal surface.
Based on same principle, when upper arm 4 and underarm 13 composite moves, the work bucket remains unchanged with the angle of horizontal surface.
The present invention satisfies the maintenance of ehv power transmission circuit and facility and installs and uses.Yin Ben mechanism is pure hydraulic gear, is not subjected to the disturbing influence of high electric field, highfield when aloft work, and the work bucket remains level in ± 1 degree, stable working.Solved the electric liquid leveling system of work bucket and only be applicable to uninsulated aerial platform, be subjected to the disturbing influence of high electric field, highfield big, signal is made mistakes easily, the problem of influence safety; Make and go up the corresponding congruence of quadrangle that underarm connecting portion linkage rod group (the IF section that comprises jointed connecting rod 15, first connecting rod 1, second connecting rod 2, upper arm 4) quadrangle that is constituted and the bucket portion linkage rod group of working (comprising the LK section of upper arm 4, KN section, third connecting rod 6, the 4th connecting rod 7 of work bucket support 9) are constituted, form a kind of aerial platform balanced structure of folding arm configuration of adaptive zone telescopic boom, it is dead-weight balanced poor to have solved the work bucket, rock greatly the problem of poor stability.
