Affiliated technical field
The utility model relates to a kind of novel Pile holding mechanism of hydraulic static pile pressing machine, and the maximum characteristics of this Pile holding mechanism are to have saved used leverage of traditional Pile holding mechanism and folder stake oil cylinder, and can guarantee that pile locking force becomes rational proportional relationship with pile driving pressure.
Background technology
The piling function of hydraulic static pile pressing machine is to clamp preformed pile (non-slip) by Pile holding mechanism, and piling oil cylinder promotion Pile holding mechanism moves downward to be realized.At present, the pile locking force of known Pile holding mechanism all is to provide by special-purpose folder stake oil cylinder: 1. or with four-hole (or six mouthfuls, eight mouthfuls) press from both sides the stake oil cylinder directly to folder; 2. or with folder stake oil cylinder clamp by various levers (containing skewback) mechanism.
1. along with continue to increase (having reached 1000 tons in the market) of static pile press tonnage, the clamping cylinder diameter has reached 500-600 to scheme, and not only processing cost is big, and the intensity of cylinder also is subjected to baptism, the more fragile oil cylinder of folder stake; Though 2. scheme reaches boosting function by lever (or skewback), thereby reduce folder stake cylinder diameter, but increased impulse stroke, the complexity and the fine finishining cost of Pile holding mechanism structure have been increased, and above two kinds of tradition folder stake scheme disadvantage are that Pile holding mechanism and piling mechanism are independent separately, there is not necessary relation between pile locking force and the pile driving pressure (as 200 tons of pile driving pressures and 1000 ton hours, pile locking force may all be the same) so not only wasted pile locking force, increased destruction, and exclusive clamps stake cylinder has also increased manufacturing cost to pile body.
Summary of the invention
To use exclusive clamps stake cylinder not only cost is higher in order to solve present Pile holding mechanism, the Pile holding mechanism failure ratio is more frequent, and pile locking force and pile driving pressure are independent mutually, there are not deficiencies such as rational proportion relation each other, the utility model provides a kind of new Pile holding mechanism, this Pile holding mechanism has been cancelled traditional Pile holding mechanism exclusive clamps stake oil cylinder, adopt the piling cylinder to be folder stake cylinder, be that the piling cylinder not only produces the piling effect, also produce folder stake effect simultaneously, so not only cancelled folder stake cylinder, reduced cost, and what is more important guarantees that pile locking force becomes with pile driving pressure closely with proportional relation, exist a kind of rational proportion to concern between they the two, thereby the reduction Pile holding mechanism is to the destructiveness of precast pile.
The technical scheme that its technical problem that solves the utility model adopts is
This folder pilework is made up of main folder stake mechanism and sub-folder stake mechanism two parts of arranging up and down, they are bound up by big screw rod, the lower secondary Pile holding mechanism presss from both sides the stake oil cylinder by the stake of linkage folder by tradition folder stake mode by one, this pile locking force need only guarantee to satisfy at 3 and get final product: the one, can overcome the deadweight of whole Pile holding mechanism, and do not glide when making it clamp pre-; The 2nd, can overcome the stratum frictional resistance that pulls up Pile feeder and run into and (after a stake position pressed, need preformed pile be delivered to the underground certain depth with special-purpose Pile feeder: the degree of depth that needs that guarantees the ground excavation); The 3rd, the flanging stake can be provided, (the edge corner location in some building site is because the restriction of locus for the required pile locking force in special stake such as angle stake position, stake machine fuselage does not arrive the position, just can only use special-purpose skirt piles, angle pile holder stake mechanism and piling mechanism come piling, the general tonnage in this type of position is less, pile driving pressure is little, required pile locking force is also not too big, comprehensive above 3 the required pile locking force of sub-folder stake mechanism is less as can be known, required oil cylinder cylinder diameter is also less, thereby skirt piles, the profile bulk of angle stake mechanism is just less, can reduce minimum skirt piles effectively, the angle pilespacing from, improve a stake machine flanging stake, the ability of angle stake.Top main folder stake mechanism links together by screw rod and lower secondary Pile holding mechanism; (skirt piles during piling; except the stake of angle) the folder stake oil cylinder of the mechanism of operation sub-folder stake earlier stretches out and drives pile-clamp by linkage and " hold " preformed pile tightly; thereby guarantee when whole Pile holding mechanism of moment that the piling oil cylinder stretches out downwards do not glide (pile-clamp of main folder stake this moment mechanism also " is not held " preformed pile tightly); the piling cylinder stretches out initiatively voussoir of downward promotion then; initiatively voussoir promotes passive voussoir; jaw clamps preformed pile thereby passive voussoir promotes main folder stake mechanism; simultaneously the active force of piling oil cylinder promotes whole Pile holding mechanism and " holds " preformed pile tightly and move downward; thereby realize the piling process; the downward active force of piling cylinder (being pile driving pressure) is big more; then the jaw of main folder stake mechanism is just big more by the component (being pile locking force) that passive voussoir obtains; thereby realize the rational proportion relation of pile driving pressure and pile locking force; protect the preformed pile surface quality better, realize piling quality preferably.
The beneficial effects of the utility model are to have saved the heavy caliber folder stake oil cylinder and the complicated leverage of traditional Pile holding mechanism, the special special-purpose flanging stake of general Pile holding mechanism, the Pile holding mechanism of angle stake have also been saved simultaneously, what is more important has realized getting in touch of pile driving pressure and pile locking force, make and keep a rational proportion relation between the two, thereby guarantee the non-slip and not excessively folder stake of pile-clamp in the piling process at any time, improved the folder quality of pile to greatest extent.
