Description
Technical field
The large-tonnage movement chassis of a kind of convertible load distribution of the present invention, belongs to heavy shifting of conveyer tool field, is specifically related to bridge prefabrication part shifting of conveyer tool.
Background technology
In bridge erection, manufacture and the transport of preformed part beams of concrete and preformed part bridge pier are all important steps wherein, and preformed part bridge pier is a kind of tall and slender structure, weight is large, center of gravity is high, and need in transportation, load distribution is even, motion is mild, transports extremely difficult.Preformed part is generally prefabricated in beam field, by equipment movement to harbour or other installation site, is installed by specialized equipment.
In the movement construction of beam field preformed part bridge pier, usually adopt two kinds of basic ways, one is transported after adopting the bottom-up jack-up bridge pier of movement chassis, i.e. movement chassis scheme.The second adopts carrying implement to mention bridge pier from top, i.e. hanging beam scheme.In hanging beam scheme, need carrying implement walking rails span enough large, can cover the manufacturing field of preformed part, the purchase commodity of carrying implement, usage charges and cost of maintenance are higher, and the process-cycle of equipment is long, and its operation is more complicated.
The prefabricated place of large bridge generally adopts movement chassis scheme, the individual layer beam that existing movement chassis is made up of two distribution beam, load is by two jacking cylinder uniform distributions, therefore at the one-sided walking rails two points stress of movement chassis, as shown in Figure 2, J, K two points stress on the track 3 contacted with chassis, therefore, the walking rails of movement chassis is had higher requirements, walking rails needs concrete pile driving to prevent track settlement, and lay sliding rail on surface, cost is very high, and service life is relatively short.
Summary of the invention
The object of this invention is to provide a kind of can load transfer distribute large-tonnage movement chassis, four-point supporting is converted to by 2 supports by movement chassis load, make the one-sided walking rails of movement chassis by two points stress be converted to 4 stressed, make its stressed more scientific evenly, not only improve movement trolley traveling track service life, and can ensure that movement chassis operates steadily and safety
The present invention a kind of can load transfer distribute large-tonnage movement chassis, by the one-sided movement chassis of two covers, PLC control system and hydraulic power unit composition, the two one-sided movement chassis both sides of cover are arranged, often overlap one-sided movement chassis by upper strata beam, lower floor's beam, support backing plate, jacking cylinder and traveling oil cylinder composition, lower floor's beam is made up of the identical lower floor distribution beam of two, Liang Ge lower floor distribution beam horizontal interval (HI) is arranged, its medial extremity is connected by pipe link, its external side end arranges jacking cylinder respectively, upper strata beam is symmetricly set in Liang Ge lower floor distribution beam, two support backing plate between Liang Ge lower floor distribution beam, be suspended on below the distribution beam of upper strata, can along upper strata distribution beam slippage, make upper strata beam depart from lower floor's distribution beam face by jacking two jacking cylinders, upper strata beam and upper load thereof drop on two jacking cylinders, form two load support points at lower floor's beam, again two are supported the surface, centre that backing plate is drawn to Liang Ge lower floor distribution beam respectively, and make two jacking cylinder unloading homings, upper strata beam and upper load thereof drop on two support backing plates of Liang Ge lower floor distribution beam, uniform load is made to be assigned to the two ends of Liang Ge lower floor beam, form four load support points at lower floor's beam, thus make the single-sided tracks face of the correspondence of two covers one-sided movement chassis by two points stress be converted to 4 stressed.
Soffit, described upper strata is provided with slide rail.
Described jacking cylinder arranges pressure sensor respectively and is connected with PLC control system with displacement pickup.
Described traveling oil cylinder is provided with displacement pickup and is connected with PLC control system.
The present invention is simple to operate, movement efficiency is high, effectively ensure that in movement process, motion is mild, improves the safety in preformed part beams of concrete and preformed part bridge pier movement process.The one-sided movement chassis of the present invention is primarily of upper strata beam, lower floor's beam, support backing plate, jacking cylinder and traveling oil cylinder composition, and lower floor's beam is made up of two identical lower floor distribution beam.The present invention is in jacking process, and one-sided two jacking cylinders support upper strata beam, and upper strata beam and upper load thereof drop on 2 strong points, two supports, clearly stressed; After jack-up component of the present invention, by movable support backing plate to the center of each lower floor distribution beam, jacking cylinder slowly bounces back, and two, one-sided movement chassis supports backing plate and supports upper strata beam and upper load thereof, and two points stress is clearly stressed; Now, oil cylinder unloads, oil cylinder does not stress, support the center that backing plate is positioned at distribution beam, the power supported on backing plate is evenly distributed on the strong point at distribution beam two ends, 2 supports respectively of Liang Ge lower floor distribution beam, clearly stressed, one-sided movement chassis forms four-point supporting, and its respective carter face is also clearly stressed, 4 average force.Structure of the present invention all adopts 2 freely-supported force structures, and reasonable stress is clear and definite, and load distribution is even, solves the difficult problem that existing track exists, thus greatly reduces the cost of manufacture of track.In addition, the one-sided movement chassis of the present invention is in movement process, and oil cylinder does not stress, and substantially increases the service life of oil cylinder.
