The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of hydraulic safety locking mechanism of induction system, comprise pipeline platform 1, the pulling axle that described pipeline platform 1 is provided with gear and is attached thereto is characterized in that: the hydraulic safety locking mechanism of described induction system also comprises oil cylinder 2, magnetic valve 3, ECU and mechanical connection mechanism 5, described oil cylinder 2 spool is connected by described mechanical connection mechanism 5 and described pulling, and described ECU is connected with described magnetic valve 3, and described magnetic valve 3 is connected with described oil cylinder 2.

Described magnetic valve 3 is to seal magnetic valve in three.When pipeline 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 sent to instruct and seal magnetic valve in three this moment, keep stable power output, be unlikely to stop causing part and anchor clamps to interfere (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 oil cylinder 2 is opposite, and the piston rod of promptly described two oil cylinders 2 is done counter motion along the medium line 4 of described pipeline platform; The adjustable height of the stroke of described oil cylinder 2 and described pipeline platform 1 is consistent.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, can control stably, get a desired effect by envelope magnetic valve in three toward the phenomenon that pushes back.

Described oil cylinder 2 be positioned at described pipeline 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 pipeline platform 1, oil cylinder promotes by piston rod in running, 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 medium line 4 of described pipeline platform and can moves along the medium line 4 of described pipeline platform, the piston rod of oil cylinder is done back and forth movement back and forth along the medium line 4 of pipeline platform, is convenient to good fit between anchor clamps and the part.

Described cutting ferrule 6 is arc, circle or rectilinear structure.

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 schematic diagram that does not increase hydraulic locking mechanism, in the actual motion, owing to there is not hydraulic safety locking mechanism, pipeline past decline under extreme higher position walking and anxious situation of stopping, and pipeline 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 pipeline rises is pre-set, but because this pressure is a reference value, can not accurately calculate the rising of whole piece pipeline and need great gas pressure, reason is that the overall weight of pipeline is that variable (constantly has new parts, solder joint, fluid 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, production line might rise unusually, and increase the hydraulic machinery locking device, then can avoid such situation to take place.

In actual conditions, increase hydraulic pressure, mechanical locking device, mainly be to consider that hydraulic mechanism operates steadily, and can provide big power output, its operation principle is: adopt two oil cylinders with the same stroke of lifting height, seal magnetic valve in one three, two oil cylinders rely on mechanical mechanism to connect a pulling axle of stuck pipeline lifter wheel section of rack, pipeline 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 magnetic 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 pipeline is whole toward descending, can produce a desired effect, the more important thing is that this version is simple, do not change the overall structure of pipeline, 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 security 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 pipeline can be toward descending.As Fig. 3, when pipeline decline put in place, the oil cylinder 21 of this mechanical-hydraulic retaining mechanism 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 pipeline 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 will be controlled in three the envelope magnetic 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 utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
