Abstract
The utility model relates to a high-rolling-pair multi-point equal-pressure pile gripping mechanism, which comprises a pile gripping box, hydraulic cylinders, hydraulic rods, a conical ring, multi-section jaws, a prefabricated pile, rolling pairs and a retainer. A plurality of hydraulic cylinders are evenly distributed above and below the pile gripping box. The hydraulic rods of the hydraulic cylinders stretch into the pile gripping box and are connected with the conical ring. A plurality of multi-section jaws are evenly distributed on the internal side of the conical ring. The internal sides of the multi-section jaws are in contact with the prefabricated pile. The rolling pairs are distributed between two parallel conical surfaces on the external sides of the multi-section jaws and the internal side of the conical ring. The high-rolling-pair multi-point equal-pressure pile gripping mechanism has the advantages that the structure is simple, the pile can be gripped stably, the force transfer efficiency of the pile gripping mechanism is high, the friction can be effectively reduced and the pile gripping mechanism is not apt to wear.
Description
Technical field
The utility model relates to a kind of Pile holding mechanism, is a kind of rolling higher pair multiple spot even pressure type Pile holding mechanism specifically.
Background technology
Pile holding mechanism is one of important spare part on the hydraulic static pile pressing machine, is one of crucial force part of hydraulic static piling work, is related to the intact degree of piling efficient, preformed pile of hydraulic static pile pressing machine and the problem of safe operation.Mostly domestic existing hydraulic static pile pressing machine is the pintongs Pile holding mechanism; There is the preformed pile discontinuity in this type of mechanism when the clamping preformed pile, the centering poor performance clips broken preformed pile or cause stake to beat tiltedly easily; Existing many lobes inclined-plane clamping device is because chucking power is too big; Cause inclined-plane stress to beat, easy abrasion, the transmission efficiency of power is lower.The power transmission efficiency of Pile holding mechanism is restricting further developing of pile press with stability.
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 rolling higher pair multiple spot even pressure type Pile holding mechanism, adopts the rolling higher pair high with the transmission efficiency of realizable force, few purpose of wearing and tearing.
The technical scheme of the utility model is: a kind of rolling higher pair multiple spot even pressure type Pile holding mechanism; Comprise pile clamping box, hydraulic cylinder, hydraulic stem, conical ring, many lobes jaw, preformed pile, rolling pair and retainer; It is characterized in that: pile clamping box a plurality of hydraulic cylinders that evenly distribute up and down; The hydraulic stem of hydraulic cylinder stretches in the pile clamping box and all is connected with conical ring; The inboard a plurality of many lobes jaws that evenly distribute of conical ring, the inboard of many lobes jaw contacts with preformed pile, is distributed with rolling pair between two conical surfaces that are parallel to each other in the outside of many lobes jaw and the inboard of conical ring.
Be provided with retainer between the said rolling pair.
The utility model has the advantages that: this mechanism structure is simple, clamps to stablize, and the power transmission efficiency of Pile holding mechanism is high, can effectively reduce friction, and is not easy to wear.
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 even up and down a plurality of hydraulic cylinders 2 that distribute of pile clamping box 1; The hydraulic stem 3 of hydraulic cylinder 2 stretches in the pile clamping box 1 and all is connected with conical ring 4; Conical ring 4 inboard a plurality of many lobes jaws 5 that evenly distribute, the inboard of many lobes jaw 5 contacts with preformed pile 6, is distributed with rolling pair 7 between two conical surfaces that are parallel to each other in the inboard of the outside of many lobes jaw 5 and conical ring 4.Be provided with retainer 8 between the rolling pair 7.
Hydraulic cylinder 2 promotes hydraulic stems 3 connected conical ring 4 is moved down during work, makes inboard rolling pair 7 drive many lobes jaws 5 and moves to the inside and compress preformed piles 6, through the insertion that drives preformed pile 6 that moves downward of casing.
