As shown in Figure 1, a kind of hydraulic safety locking mechanism of delivery system, comprise travel line platform 1, described travel line platform 1 is provided with gear and spurs axle with described gear bonded assembly, it is characterized in that: the hydraulic safety locking mechanism of described delivery system also comprises oil cylinder 2, electromagnetic valve 3, ECU (Electrical Control Unit) and mechanical connection mechanism 5, described oil cylinder 2 spool is connected by described mechanical connection mechanism 5 and described pulling, described ECU (Electrical Control Unit) is connected with described electromagnetic valve 3, and described electromagnetic valve 3 is connected with described oil cylinder 2.
Described electromagnetic valve 3 is to seal electromagnetic valve in three.When travel line rises to the extreme higher position, this moment, one of them oil cylinder 2 was released stroke to maximum, another one oil cylinder 2 strokes are return and are put in place, ECU (Electrical Control Unit) sent to instruct and seal electromagnetic valve in three this moment, keep stable power output, be unlikely to stop causing part and anchor clamps to produce interference (collision) phenomenon because of anxious.
Described oil cylinder 2 is for having two oil cylinders of identical stroke; The piston rod movement direction of described two oil cylinders 2 is opposite; The adjustable height of the stroke of described arbitrary oil cylinder 2 and described travel line platform 1 is consistent.Piston rod on described two oil cylinders 2 is done counter motion along described travel line flat-bed medium line 4, cooperate by heterodromous oil cylinder, because the resistance to pressure of hydraulic oil, thereby guarantee that the oil cylinder piston bar can not bounce back or the past phenomenon that pushes back, can carry out pulsation-free control by envelope electromagnetic valve in three, get a desired effect.
Described oil cylinder 2 be positioned at described travel line platform 1 medium line 4 both sides up and down and be positioned at the both sides of described mechanical connection mechanism 5.Oil cylinder lays respectively at the both sides of described medium line 4, and an end of fixed oil cylinder in the mechanical connection mechanism 5, an other end of oil cylinder then is fixed on the travel line platform 1, oil cylinder promotes by piston rod in operational process, when oil cylinder piston bar on one side arrives range, another one oil cylinder piston bar is return and is put in place, vice versa, and such version is simple, and convenient control and operation.
Described bindiny mechanism 5 is provided with the cutting ferrule 6 of stuck described pulling axle; Described cutting ferrule 6 is positioned at the one-sided of described mechanical connection mechanism 5; Described mechanical connection mechanism 5 is fixed on the described travel line flat-bed medium line 4 and can moves along described travel line flat-bed medium line 4, the piston rod of oil cylinder is done back and forth movement back and forth along travel line flat-bed medium line 4, is convenient to good fit between anchor clamps and the part.

Described mechanical connection mechanism 5 piston rods perpendicular to described oil cylinder 2; The end of described piston rod and described mechanical connection mechanism 5 are fixed.
Fig. 2 then is the scheme drawing that does not increase hydraulic locking mechanism, in the real-world operation, owing to there is not hydraulic safety locking mechanism, travel line past decline under extreme higher position walking and anxious situation of stopping, and travel line was still carried body in white to advance or was retreated this moment, thereby bodywork parts and anchor clamps have taken place interfered (collision) phenomenon, producing such reason then is, the outer pilot pressure that travel line rises is pre-set, but because this pressure is a reference value, can not accurately calculate the rising of whole piece travel line and need great gaseous tension, reason is that the overall weight of travel line is that variable (constantly has new parts, solder joint, sealant is increased to above the vehicle body), and what is more important we can not this pressure set too high, because it is too high that pressure is set, under the effect of the unstable source of the gas in the external world, manufacturing line might rise unusually, and increase the hydraulic machinery latching device, then can avoid such situation to take place.
In actual conditions, increase hydraulic pressure, mechanical locking device, mainly be to consider that hydraulic gear operates steadily, and can provide big power output, its principle of work is: adopt two oil cylinders with the same stroke of rise height, seal electromagnetic valve in one three, two oil cylinders rely on mechanical mechanism to connect a pulling axle of stuck travel line lifter wheel section of rack, travel line is rising under the situation of extreme higher position, one of them oil cylinder is released range, another oil cylinder is return and is put in place, automatically controlled send instructions to electromagnetic valve this moment, three hydraulic valves mediate, because the resistance to pressure of hydraulic oil, even if this moment, two oil cylinder load-bearing strengthened, the oil cylinder piston bar can be toward retraction or toward pushing back yet, the power that passes to the pulling axle can not change yet, just can be thereby travel line is whole toward descending, can produce a desired effect, the more important thing is that this version is simple, do not change the integral structure of travel line, can be used as replenishing of original structure, just calculating of doing needs to adopt the oil cylinder of much cylinder diameters to guarantee power output.The safety of producing improves greatly, is running under the situation that urgency is stopped or air pressure is not enough, and hydraulic locking mechanism can play a role equally, can guarantee fully that travel line can be toward descending.As Fig. 3, when travel line decline put in place, the oil cylinder 21 of this mechanical-hydraulic catch gear was in the state of stretching out, and oil cylinder 2 is in contraction state, and 6 of cutting ferrules play the effect of stuck pulling axle, relay cylinder power output.Equally, when the travel line rising puts in place, this moment, oil cylinder 21 was in contraction state, 2 of oil cylinders are in the state of stretching out, when motion puts in place, ECU (Electrical Control Unit) will be controlled in three the envelope electromagnetic valve and come operation that oil cylinder is rationalized, thereby avoid the interference (collision) of part and anchor clamps, minimizing unnecessary loss.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
