Abstract
The utility model relates to a precast pile clamping device for the pile foundation, in particular to a prestressed concrete tubular pile clamper, which comprises a box body. A movable pile clamping circular arc plate and a still pile clamping circular arc plate are respectively allocated at the two sides in the box body; the different points are as follows: the still pile clamping circular arc plate is hinged with one side of the box body through a hinged support, and the movable pile clamping circular arc plate is hinged with a telescopic oil cylinder at the other side of the box body through a hinged support. The utility model has the advantages that the largest clamping area can be kept between the pile clamping circular arc plates and a concrete tubular pile because the regulating action of the hinged supports, meanwhile, the relative position of a pile head and the box body can be agilely regulated at any time in the driven pile process to cause the pile head part to uniformly bear the force to avoid the unpredictable pile occurring in order to economize the cost, and the delay of the construction period is reduce; the structure is simple and reasonable, and the utility model is conveniently used and operated.
Description
Technical field
The utility model relates to a kind of preformed pile clamping device that is used for pile foundation construction, particularly a kind of prestressed concrete pipe pile clamper.
Background technology
In pile foundation construction, behind the clamp holder clamping preformed pile pile crown, preformed pile is sunk by the power of impulsing of transmitting the generation of high frequency hydraulic vibration pile pulling sinker.Prestressed concrete pipe pile clamper commonly used includes a square box, disposes a folder stake arc plate in casing, and folder stake arc plate and pile clamping box body are for being rigidly connected or simple chain connects.In the pile sinking use, usually because the position between folder stake arc plate and the tubular pile head is difficult to adjust, make pile crown unbalance stress and cause pile crown by not bad phenomenon, cause waste on the cost and the delay on the duration.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of prestressed concrete pipe pile clamper at the deficiency of above-mentioned prior art existence, it can be implemented in the pile driving process, along with stressed difference, automatically adjust the contact condition between folder stake arc plate and the tubular pile head flexibly, make the stressed even of pile crown part, thereby avoided the generation of other stake.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include a casing 1, both sides dispose dynamic and static folder stake arc plate 3,2 respectively in casing, its difference is, described quiet folder stake arc plate 2 is hinged with casing one side by hinged 4, and moving folder stake arc plate 3 is hinged with the telescopic oil cylinder 6 of casing opposite side by hinged 5.
According to technique scheme, described hinged 4,5 is that bulb is hinged.
Advantage of the present utility model is: 1. because hinged regulating action, make between folder stake arc plate and the concrete tubular pile and keep maximum clamping area, in pile driving process, can adjust simultaneously the relative position between pile crown and casing at any time flexibly, make the pile crown part stressed evenly, avoid the generation of other stake, thereby saved cost of production, reduced the delay on the duration; 2. simple and reasonable for structure, operation is very easy in use.
Description of drawings
Fig. 1 is the positive sectional structure chart of an embodiment of the present utility model
Fig. 2 is the A-A sectional view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, 2, include a rectangular box 1, the lower end of casing is provided with opening, and a side disposes quiet folder stake arc plate 2 in casing, and quiet folder stake arc plate is hinged by bulb hinged 4 and casing one side, and opposite side disposes moving folder stake arc plate 3 in casing.Rear end at moving folder stake arc plate is hinged by bulb hinged 5 and telescopic oil cylinder 6, and telescopic oil cylinder is installed in the casing outside, and its piston rod puts in casing and bulb is hinged connects firmly, or it is hinged directly piston rod end to be arranged to bulb.In addition, for ease of the importing of preformed pile pile crown, can import inclination angle 7 to form in the following end periphery chamfering of folder stake arc plate.When the preformed pile pile crown stretch into put in place in the clamper after, telescopic oil cylinder stretches out, the reach of moving folder stake arc plate just can clamp the preformed pile pile crown.Clamp or later pile driving process in, because it is hinged that folder stake arc plate two ends and pile clamping box body are bulb, it can be along with stressed difference, automatically adjust the clamp position between folder stake arc plate and the tubular pile head flexibly, make the stressed even of pile crown part, thereby avoided the generation of other stake phenomenon.
