Abstract
The utility model provides a double-shred-rod force-increasing multipoint pressure-equalizing pile gripping mechanism. The mechanism comprises a pile gripping box, a hydraulic cylinder, a hydraulic rod, an internal connecting rod, an external connecting rod, a pressing flap and a precast pile, wherein the hydraulic rod of the hydraulic cylinder mounted outside the pile gripping box extends into the pile gripping box to be hinged at the same point together with the internal connecting rod and the external connecting rod; the other end of the external connecting rod is hinged on the pile gripping box; the internal connecting rod is hinged on the pressing flap; and the pressing flap is in contact with the precast pile. The double-shred-rod force-increasing multipoint pressure-equalizing pile gripping mechanism provided by the utility model has the advantages of simple and compact structure, long pressing flap travel, large force increasing ratio, high force transmission efficiency and stability in motion.
Description
Technical field
The utility model relates to a kind of Pile holding mechanism, is a kind of multiple twin bar reinforcement multiple spot even pressure type Pile holding mechanism specifically.
Background technology
As the key mechanism of hydraulic static pile pressing machine, Pile holding mechanism is the main execution unit of hydraulic static pile pressing machine tool operation, and stable and the high-performance of Pile holding mechanism determined tonnage, operating efficiency and the safety of piling machinery.Existing piling machinery generally adopts hydraulic cylinder directly to press from both sides an a formula and taper ring folder stake formula on the market, and not only pile locking force is inhomogeneous for the former, and force increasing ratio is zero, and aligning performance is poor, and latter's friction is bigger, presses the lobe stroke little, and force increasing ratio is little.Improve the difficulty that Pile holding mechanism has become mechanical tonnage, efficient and the safety of increase piling to defeat.
The utility model content
In order to overcome the deficiency that above-mentioned technology exists, the utility model technical problem to be solved provides a kind of multiple twin bar reinforcement multiple spot even pressure type Pile holding mechanism, adopts multiple twin bar force-increasing mechanism, and is simple with implementation structure, presses the lobe stroke long, the purpose that force increasing ratio is big.
The technical scheme of the utility model is: a kind of multiple twin bar reinforcement multiple spot even pressure type Pile holding mechanism; Comprise pile clamping box, hydraulic cylinder, hydraulic stem, inside connecting rod, outside connecting rod, pressure lobe, preformed pile; It is characterized in that: the hydraulic stem that is installed in the outside hydraulic cylinder of pile clamping box stretches into pile clamping box inside and is articulated in same point with inside connecting rod and outside connecting rod; The other end of outside connecting rod is hinged on the pile clamping box, and inside connecting rod is hinged on presses on the lobe, presses lobe to contact with preformed pile.
Outside connecting rod-pressure lobe-hydraulic stem mechanism is that the center distributes ringwise with the preformed pile axis in said.
The utility model has the advantages that: this mechanism structure is simple, compact, and pressure lobe stroke is long, force increasing ratio is big, and the power transmission efficiency is high, motion stabilization.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Combine accompanying drawing at present, the technology contents of the utility model is described further.
As shown in Figure 1; The hydraulic stem 3 that is installed in the hydraulic cylinder 2 of pile clamping box 1 outside stretches into pile clamping box 1 inside and is articulated in same point with inside connecting rod 4 and outside connecting rod 5; The other end of outside connecting rod 5 is hinged on the pile clamping box 1, and inside connecting rod 4 is hinged on presses on the lobe 6, presses lobe 6 to contact with preformed pile 7.Outside connecting rod-pressure lobe-hydraulic stem mechanism is that the center distributes ringwise with the preformed pile axis in said.
