Detailed description of the invention
By describing technology contents of the present invention, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 to Fig. 3, the invention provides a kind of jacking system of fluid pressure type, comprise base 1, base is arranged with cardan wheel 2, base 1 is provided with multistage hydraulic push rod 3, multistage hydraulic push rod is made up of multiple mutually nested hydraulic mandril, greatly can increase the length of the elongation of hydraulic mandril.Be flexibly connected with base at the left surface of multistage hydraulic push rod 3, can be flexibly connected by bolt, hydraulic mandril can be rotated around flexible connection point.The top of multistage hydraulic push rod is provided with platform 4, and platform is for the people that stands.The left surface of multistage hydraulic push rod is connected with one end of hydraulic supporting strut 5, preferably this flexible connection point be arranged on base be flexibly connected above point, such setting is more reasonable.The hydraulic supporting strut other end is connected with base, and hydraulic supporting strut is connected with distributing valve with multistage hydraulic push rod, and distributing valve is connected with hydraulic compressor.
In use, first hydraulic mandril can shorten in the present invention, can pass through highly lower ground side in mobile.Needing the place reducing height further, hydraulic supporting strut can be passed through, hydraulic mandril is tilted, as shown in Figure 1, so again reduce height, the vertex of hydraulic mandril also can offset directly over base simultaneously, can block unscreened place, both sides by road crown center, namely allow the vertex of hydraulic mandril by unscreened place, both sides, thus allow jacking system of the present invention easily movement.The setting of hydraulic supporting strut reduces the labour intensity of rotational hydraulic push rod.And the present invention is when needs raise use, as shown in Figure 3, by hydraulic supporting strut, hydraulic mandril can be erected postpone, control distributing valve, allow the liquid driven hydraulic mandril upwards jack-up of hydraulic compressor, make platform to rising, people can rise along with platform, thus realizes raising.
Being convenient to from platform upper and lower to realize people, can, by arranging ladder on platform, can considering to arrange rope ladder etc.Certainly the ladder arranging rigidity is relatively good practicality, and the ladder of rigidity how to stretch be problem.In order to solve this problem, the present invention proposes the ladder 6 being connected to square on every one-level hydraulic mandril top of multistage hydraulic push rod, the scheme that the ladder of the square that every one-level hydraulic mandril top connects is mutually nested.Concrete nested procedure can be that the square ladder that connects of nethermost hydraulic mandril is near hydraulic mandril, the ladder that hydraulic mandril then below second connects is against innermost ladder, close to each other like this, be convenient to the ladder when hydraulic mandril shrinks and also shrink.When hydraulic mandril stretches elongated, ladder also stretches elongated, and is close together, and is convenient to climbing.Preferred ladder is arranged on the right side of hydraulic mandril, can not affect the work of the hydraulic supporting strut in left side.
Time hydraulic mandril stretches, by closing distributing valve, thus the current location of hydraulic mandril can be kept, avoiding hydraulic retract to fall after rise.When distributing valve fault, hydraulic mandril may automatic fall-back, may cause the problem of injury to personnel on platform.In certain embodiments, can pass through self-locking mechanism, described self-locking mechanism is arranged between adjacent ladder, avoids the mutual contractile motion of solar.Self-locking mechanism is set because bad on hydraulic mandril, also bad self-locking mechanism is controlled.Self-locking mechanism can be a detent mechanism, namely allows ladder extend and can not shrink, avoids ladder to fall after rise, thus avoid hydraulic mandril to shrink.And when needing to shrink, only need people to climb on ladder, control to allow self-locking mechanism lose efficacy, hydraulic mandril can be allowed to shrink.
Owing to being cardan wheel below base, then when aloft work, may slide, and cause the situation of injury to personnel, in certain embodiments, described base is also provided with folding bracing or strutting arrangement 7, base is provided with the groove 8 holding described bracing or strutting arrangement.Base can be lifted by bracing or strutting arrangement makes wheel leave ground, and the direct base for supporting of bracing or strutting arrangement, avoids the slip of base, and bracing or strutting arrangement too increases Area of bearing simultaneously, avoids jacking system tilt and fall down.Groove 8 can allow bracing or strutting arrangement can be received on base, and volume when jacking system is moved is less, and when supporting, can launch, and increases the area of contact on base and ground, makes base more firm.
The present invention does not limit the shape of platform, and can be a shaped as frame, people may stand in frame, and in certain embodiments, described platform is the flat board perpendicular to staircase side, and structure is simple, is convenient to produce.
In order to increase safety, avoid again the height increasing this device, four dull and stereotyped sides are provided with folding railing 9 simultaneously.When this device mobile, railing 9 can put down, and as shown in Figure 1, avoids the height adding this device, ensure that the crossing ability of this device.In use, as Figure 2-3, can railing be propped, form a fence, increase safety.
The present invention in some cases, extends after hydraulic mandril can being tilted to the left again, can get at the upper left place of base like this, is applicable to situation when cannot park this device in the place on the base left side.At this time people stands on platform, can form larger pressure, need larger hydraulic supporting strut just can support, can cause the increase of cost like this hydraulic pressure support bar.In certain embodiments, the left side of hydraulic supporting strut can be provided with back-up block 10, back-up block is connected with base, and back-up block is for supporting the multistage hydraulic push rod be tilted to the left.By back-up block pillar stiffener hydraulic mandril, just without the need to larger hydraulic supporting strut, as long as strut bar can rotational hydraulic push rod.
In order to avoid hydraulic mandril operationally double swerve, base is also provided with lockout mechanism 11, lockout mechanism is arranged on the right side of multistage hydraulic push rod, and lockout mechanism is used for the relative position at locking hydraulic mandril and base.Namely lockout mechanism for fixing, has multiple implementation.Can adopt a supporting blade in the present invention, as Figure 1-3, supporting blade two ends have through hole, and base is provided with through hole, and the right flank of multistage hydraulic push rod is provided with through hole, and a through hole of supporting blade is flexibly connected by bolt with the through hole of base.When hydraulic mandril motion put in place need locking time, by another of supporting blade by after being bolted with the through hole of hydraulic mandril, namely hydraulic mandril is fixed, and can not rotate.
Distributing valve of the present invention can be manual or be preferably electronic type distributing valve.The switch of electronic type distributing valve can be arranged on many places, is convenient to control.Distributing valve can realize the control to hydraulic mandril and hydraulic supporting strut.
In certain embodiments, conveniently to the Long-distance Control of jacking system, also comprise wireless controller and wireless receiver, wireless receiver is connected with electronic type distributing valve, wireless controller is used for transmitting control signal, and described wireless switching is used for controlling electronic type distributing valve after receiving control signal number.
The foregoing is only embodiments of the invention; not thereby scope of patent protection of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
