Description
Technical field
The present invention relates to a kind of drag chain support device, particularly relate to a kind of super gravity field drag chain support device drag chain total travel being propped up to overfill protection.
Background technique
Drag chain is linked by numerous unit and forms, and rotate freely between link unit, whole outer likeness in form tank chain, is suitable for use in reciprocating occasion, can play traction and protective action to built-in cable, oil pipe, tracheae, water pipe etc.
Such as, geotechnical centrifuge tool hand is the necessaries that centrifuge completes test operation in running, and drag chain is the efficient mechanism of the protection of geotechnical centrifuge tool hand pipeline and traction.Along with the development of Geotechnical Engineering, in order to the comparatively actual ground work progress of real simulation, geotechnical centrifuge tool hand structure becomes increasingly complex, and involved pipeline gets more and more, and its stroke is also increasing.In order to improve the effective travel of mechanism hand in the limited hanging basket space of geotechnical centrifuge, drag chain can only select small and exquisite, compact plastics drag chain, and adopts horizontal mounting type.
Under super gravity field, level install drag chain deadweight and drag chain gut line produce centrifugal action under and make overhanging portion sagging.Along with the growth of overhanging portion, when the centrifugal force that overhanging portion produces exceedes the bearing capacity of drag chain, drag chain will be caused to destroy.Facts have proved, the pendulous tank that drag chain carries under super gravity field is very little.The destruction of drag chain can cause drag chain inner cable to damage, thus the mechanism hand worked under making super gravity field is uncontrollable, and then may cause the damage of equipment.Therefore, under super gravity field, drag chain is supported to reduce its pendulous tank extremely important.
For solving drag chain unsettled destruction in Long Distances running under super gravity field, mainly contain two kinds of solutions at present:
1, adopt vertical mounting type to replace horizontal mounting type, the centrifugal force that the deadweight of such drag chain and drag chain gut line produce is carried by mounting plane.The defect of this mode is: Long travel can be avoided to run the unsettled destruction of generation though vertically install drag chain, but this mounting type takes up room greatly, under this will make mechanism hand install hanging basket space boundary situation, the stroke of mechanism hand shortens greatly, thus reduce Robot actions space, so vertically mounting type is unsuitable for the drag chain installation of the mechanism hand of geotechnical centrifuge.
2, arrange drag chain supporting structure, the centrifugal force that drag chain overhanging portion causes is carried by supporting structure.Current known drag chain supporting structure has two kinds, i.e. roller type drag chain supporting structure and ancillary supporting device for drag chain.
Wherein, roller type drag chain supporting structure is supported by the pair of rollers drag chain that position is fixing.In order to not interfere the movement of drag chain, roller type drag chain supporting structure can only be arranged on the inaccessiable position of drag chain crooked position, it is unsettled and cannot add support that this will make drag chain in whole stroke range, at least there will be four/one stroke length, when this drag chain for Long travel works under super gravity field, the centrifugal force that unsettled drag chain long like this produces has exceeded the utmost carrying ability of drag chain.
Ancillary supporting device for drag chain is patent of invention, the patent No. is " ZL201010541314.4 ", patent name is " ancillary supporting device for drag chain ", it comprises a pair support single that pairing uses, this support single comprises and vertically to arrange and top is provided with the supporting base of horizontal mounting hole, and be arranged on the back shaft in described horizontal mounting hole by resetting means, wherein this back shaft comprises the supporting portion that original state partly leans out described mounting hole, correspondingly, the supporting portion of a pair support single is relative, supporting portion is provided with the inclined-plane to adduction extending to outside end face towards the position that drag chain bends simultaneously, and in a state of use, described horizontal mounting hole can hold described supporting portion completely.The major defect of this device is: though this device can normal gravity field realize drag chain in advance process crooked position cross over supporting portion and realize drag chain total travel support, drag chain retreat time, crooked position be difficult to cross over supporting portion; In addition, the axial setback force in supporting portion derives from the axial thrust load that drag chain produces behind inclined-plane, supporting portion the radial compression applied of supporting portion, when this device is used for super gravity field, drag chain crooked position divides the centrifugal action of generation when supporting portion, the stressed retraction in supporting portion can be caused, thus make supporting portion misoperation and lost efficacy.
In sum, the drag chain not having rational scheme solution level to install at present problem of unsettled destruction in Long Distances running under super gravity field, the mechanism hand drag chain used especially not having rational scheme to solve geotechnical centrifuge problem of unsettled destruction in Long Distances running under super gravity field.
Summary of the invention
