Abstract
The utility model discloses a pile clamp device for a pile press machine, which overcomes the broken pile phenomenon of prior art during contracting or pressing pile, for in the bad job condition the earth surface has an unbalanced bearing ability to the pile press machine, so the pile driver body tilts, and owing to the manufacturing form error of the precast pile, the clamping gates are in point-contact with the pile. The utility model comprises a box, a hydraulic cylinder and a gate in the box, the box comprises upper and lower layers of hydraulic cylinders, each hydraulic cylinder shaft is fixed with a cylindrical surface aligning block, one end of the gate is connected with the cylindrical surface aligning block, and the other end is a free end in surface contact with the precast pile. In each working surface every gate is provided with a degree of freedom in surface contact with the precast pile, and each gate does not limit other gate in the same plane, therefore, the utility model can regulate the contact between the pile clamp device and the precast pile surface to reduce pile body breakage.
Description
Technical field
The utility model relates to a kind of clip pile device, especially, relates to a kind of clip pile device for pile press machine.
Background technology
At building field, the work of static pile press machine is " to hold " prefabricated pile tightly by the clip pile device, adopts machinery or hydraulic-driven static press piling.The desirable duty of clip pile device is that the clip pile surface of pile-clamp contacts with prefabricated pile surface 100%, makes pile tube stressed evenly.Yet, be impossible in practice.This is because in actual job, its condition of work is very abominable, because the weak soil face of land is to the bearing capacity imbalance of stake machine, make the inclination of pile forming machine fuselage, in addition, because the form error that preformed pile is made, make that appearance point contacts between pile-clamp and the stake, make the stressing conditions deterioration of prefabricated tubular pile.Along with improving constantly of pile press piling ability, and the raising of pile tube termination pressure, require " holding tightly " power increasing, the phenomenon of stake usually appears clipping broken when holding tightly or in the piling process.Therefore except the workmanship of prefabricated pile itself, the damage of prefabricated pile mainly contains following two kinds of situations:
1. as shown in Figure 1, Fig. 1 is the side view of expression clip pile device when clip pile, figure king-pile 1, and clip pile device 2, the thrust of clip pile hydraulic cylinder is P.Because the fuselage of clip pile device tilts so that pile tube in vertical plane with the relative deflection of jaw, a, it is excessive that 2 of b locate local pressure, becomes the dangerous position that very easily breaks.
2. as shown in Figure 2, Fig. 2 is the top view of expression clip pile device when clip pile, and wherein identical Reference numeral represents identical unit.Since the deviation from circular from of preformed pile, or, make a among the figure because the error of folder stake device box machining makes four jaws decentraction in horizontal plane, and the local pressure that b, c are ordered is worse off, and causes stake to be clipped broken.
This has a strong impact on piling quality, piling efficient and economic benefit.The immediate cause that causes this situation to take place is the geometric error that original clip pile device can not adapt to fuselage injustice and prefabricated pile immediately.
The utility model content
In order to address the above problem, purpose provides a kind of surface applying simple in structure, that can regulate clip pile device and prefabricated pile clip pile device that is used for pile press machine good, that reduce the pile body breakage to the utility model exactly.
Clip pile device of the present utility model, comprise casing and the hydraulic cylinder, the jaw that are located in the casing, in four faces of casing three, every face comprises up and down two hydraulic cylinders, axle at each hydraulic cylinder is fixed with a cylinder aligning piece, one end of described jaw is connected with cylinder aligning piece, and the other end of itself and described end is the free end with the prefabricated pile Surface Contact.
Clip pile device of the present utility model, the up and down parallel placement of two-layer hydraulic cylinder that every face comprises in the wherein said casing.
Clip pile device of the present utility model, wherein in each casing, two respectively with the hydraulic cylinder of described two parallel placements on the jaw that connects of cylinder aligning piece, its free end is faced mutually.
Folder stake device of the present utility model, wherein said two hydraulic cylinders are arranged up and down.
Clip pile device advantage of the present utility model is: because above-mentioned structural design, the free end of jaw and prefabricated pile Surface Contact, therefore, in each working face, each jaw has the free degree with the prefabricated pile Surface Contact, and another jaw when working does not simultaneously restrict mutually, therefore, can regulate the surface of clip pile device and prefabricated pile and fit, thereby reduce the pile body breakage.
Other details of clip pile device of the present utility model and characteristics can be cheer and bright by reading the embodiment hereinafter encyclopaedize by reference to the accompanying drawings.
Description of drawings
Fig. 1 is the existing side view of clip pile device when clip pile of expression;
Fig. 2 is the schematic diagram of the top view invention of the existing clip pile device of expression when clip pile;
Fig. 3 is the local diagram of the side-looking of the utility model clip pile device;
Fig. 4 is that the A-A of the utility model clip pile device is to local diagram.
The specific embodiment
Folder stake device of the present utility model, as shown in Figure 3, comprise casing 4, be located at hydraulic cylinder 5 and jaw 2 in the casing, in the casing 4 of preformed pile 1 one sides, comprise two parallel hydraulic cylinders 5 in the present embodiment, on the axle of each hydraulic cylinder 5, be fixed with a cylinder aligning piece 3, one end of described jaw 2 is connected with cylinder aligning piece 3, and it is the free end that contacts with preformed pile 1 surface with the other end of described end, as shown in Figure 3.In the present embodiment, two respectively with the hydraulic cylinder 5 of two parallel placements on the jaw 2 that connects of cylinder aligning piece 3, its free end is faced mutually, to contact with prefabricated pile 1 formation face.
As shown in Figure 4, it be among Fig. 3 A-A to local diagram, the clip pile device of present embodiment has orthogonal 4 casings, and the jaw 2 that eight cylinder aligning pieces make can be swung along cylindrical axis, initiatively fit with prefabricated pile 1 surface in its clip pile surface, pile holding situation in the time of can effectively improving piling reduces the pile body breakage, and is simple in structure, be suitable for suitability for industrialized production, can support the use with the pile press machine of various models.
Claims (3)
1, a kind of folder stake device that is used for pile press, comprise casing, be located at the hydraulic cylinder in the casing, and jaw, it is characterized in that three every faces in four faces of casing comprise two hydraulic cylinders up and down, be fixed with a cylinder aligning piece on the axle of each hydraulic cylinder, an end of described jaw is connected with cylinder aligning piece, and it is the free end that contacts with the preformed pile surface with the other end of described end.
