Description
Technical field
This invention is related to a kind of topology layout of horizontal support legs oil circuit trend.Particularly manual type horizontal support legs case is stretched
When no oil cylinder carry out rigidity guiding hydraulic circuit trend, be adapted to pass through horizontal extension outrigger box by oil circuit introduce other execution
In the equipment of mechanism, such as truck with loading crane, power oil sources is incorporated into vertical leg hydraulic cylinder by horizontal support legs case
In.
Background technology
Horizontal support legs and vertical leg generally existing on engineering mechanical device, existing major technique has several as follows.
（One）The all-hydraulic automatic telescopic mode of the outside steel pipe market hydraulic oil of cross cylinder.As shown in figure 1, horizontal support legs
With the oil circuit trend of vertical leg, rely on the steel pipe transmission being fixed on cross cylinder, two oil pipes are separated by oil cylinder simultaneously
Both sides, eventually pass through movable supporting legs case head upper surface or fabrication hole that lower surface is opened leads to Vertical Cylinders hydraulic lock, its
The rod chamber of middle Vertical Cylinders and cross cylinder shares same oil pipe.
（Two）The all-hydraulic automatic telescopic mode of oil cylinder delivered inside hydraulic oil.As shown in Fig. 2 entering the liquid of vertical leg
Force feed is to be realized by the core pipe within cross cylinder, is provided with hydraulic fluid port in the head of cross cylinder and afterbody, directly by liquid
Pressure pipe is connected to the hydraulic lock of Vertical Cylinders.
（Three）Add the all-hydraulic automatic telescopic mode of leading block.As shown in figure 3, this oil cylinder has the telescopic cylinder of two stages, use
In driving Multi-section active outrigger box, because the restriction of movable supporting legs case inner space and cross cylinder stroke are longer, led by adding
To pulley, change oil circuit trend, oil pipe passes through leading block and moves with horizontal support legs case inside outrigger box, eventually passes through activity
The fabrication hole that outrigger box head end is opened is connected to Vertical Cylinders hydraulic lock, but the oil circuit of the oil circuit of Vertical Cylinders and cross cylinder
It is completely self-contained.
（Four）Manual telescopic mode.As shown in figure 4, by introducing oil clot, external oil pipe is incorporated into movable supporting legs case
The lower surface gap of upper surface and fixed supporting leg case upper plate in, then draw through the support at movable supporting legs case afterbody directive wheel again
Enter to inside movable supporting legs case, be also finally that the fabrication hole opened through movable supporting legs case end face is connected to Vertical Cylinders hydraulic lock.
Above-mentioned four kinds of supporting leg oil circuits move towards in method, and first three horizontal support legs are all that hydraulic-driven is stretched.Method one is
A kind of conventional oil circuit trend, is suitable for general horizontal support legs box structure, larger due to needing to open in movable supporting legs case head
Technique piping hole, the stress in impact structure.Method two is suitable for the larger structure in cross cylinder bar footpath in horizontal support legs case,
So two to three core pipes can be planted it is clear that cost and technique all greatly increase in piston rod inner.Method three is suitable for two
Level horizontal support legs box structure, assembly pulley can change oil pipe trend it is also possible to supports hoseline, but assembly pulley layout is complex,
Also it is not fee from the friction of flexible pipe and box house, need also exist for larger pipe fabrication hole excessively is opened on outrigger box.
Above-mentioned four kinds of supporting leg oil circuits move towards in method, and method one and method three are all by the steel pipe guiding outside oil cylinder and oil cylinder

Existing hydraulic oil transmission it is clear that this three kinds of methods are all inapplicable in manual type landing leg stretching, and in outrigger box section width
It more difficult to realize during reduction.Though method four gives a kind of manual supporting leg oil circuit trend, but still has the disadvantage that：First, activity
Lower limb case section differs larger with fixed supporting leg section, and the gap between fixed supporting leg case and movable supporting legs case section is relatively under normal conditions
Greatly, can exist during the stress that works and upwarp, and stress concentrates on end, there is discount to structural behaviour.Second, pull-out and
When pushing back, sebific duct all can rub with the pulley bracket of movable supporting legs case afterbody, easy damaged flexible pipe, especially in propelling landing leg case,
Oil pipe will fall in the chivalrous small-gap suture with fixed supporting leg case for the movable supporting legs case, and movable supporting legs case upper plate afterbody seamed edge promotes glue by force
Pipe, so that sebific duct local buckling radius is too small and stress is excessive, also to a certain degree damages sebific duct, affects life in application.
As can be seen here, in hydraulically powered supporting leg oil circuit, when there being cross cylinder, when vertical, oil path in oil cylinder can depend on
Cross cylinder, when no cross cylinder, the trend of hydraulic tube need to overcome following difficulty：（1）Guarantee that oil pipe can servo-actuated movable supporting legs
Case is overhanging and retracts；（2）When extending and retracting, oil pipe will not be by clamping stagnation, abrasion, not the pushing back and pulling out of interference level supporting leg；
（3）Guarantee that oil pipe moves towards nature it is easy to dismounting and replacing, be easy to examination and maintenance；（4）Oil pipe be difficult excessively exposed in fitness machine
