FIG. 1 is a schematic diagram of one embodiment of the present invention.

Fig. 2 is a top view of one embodiment of the stake buckle of the present invention.

Reference numerals: the pipe pile comprises a pipe pile fastener 1, a wedge block 2, a fastener handle 3, a connecting rod 4, a lifting rope 5, a limiting block 6 and a buffer layer 7.

Detailed Description

The embodiments of the present invention will be described in more detail with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments of the present invention after studying the specification. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The utility model provides a PHC tubular pile hoisting device which comprises a tubular pile buckle 1 and a wedge block 2 inserted between the tubular pile buckle 1 and a tubular pile and arranged at the bottom of the tubular pile buckle 1. Tubular pile is detained 1 and is the loop configuration, cup joints in the tubular pile outside to insert voussoir 2 in tubular pile is detained 1 bottom and is strengthened tubular pile and detain the frictional force between 1, and the frictional force of the gravity oppression voussoir 2 production of tubular pile can firmly be fixed the tubular pile on tubular pile is detained 1 in the hoist and mount in-process, and the mounting means is simple and easy simultaneously, has improved hoist and mount efficiency. In the embodiment shown in fig. 1-2, the pipe pile fastener 1 can be made of steel, the wedge 2 can be made of wedge nylon plastic, the friction coefficient is high, and before hoisting, the wedge 2 can be placed on each side of the pipe pile.

The tubular pile is detained 1 outside and is provided with about axis centrosymmetric a plurality of connecting device in the tubular pile is detained, connecting device is used for detaining the tubular pile and is connected with the lifting hook of hoist. The connecting device comprises two buckling handles 3 arranged on the tubular pile buckle 1, two connecting rods 4 arranged between the buckling handles 3 and lifting ropes 5 sleeved on the connecting rods 4. Specifically, in the embodiment shown in fig. 1-2, the tubular pile fastener 1 is provided with two connecting devices; the buckling handle 3 can be in a block shape and made of the same metal material as the tubular pile buckle 1, the buckling handle 3 can be welded on the tubular pile buckle 1 and can also be integrally formed with the tubular pile buckle 1, deformation and tearing are avoided, and the hoisting safety is guaranteed; the connecting rod 4 is a metal cylinder; the lifting rope 5 can be a steel wire rope.

When the device works, a tubular pile buckle can be sleeved into one end of a tubular pile, then a plurality of wedge blocks are uniformly inserted into a crack between the tubular pile and the tubular pile buckle around the tubular pile and positioned at the bottom of the tubular pile buckle in the hoisting process, then a plurality of lifting ropes are fixedly connected to a lifting hook of a crane, so that the tubular pile is vertically hoisted, the tubular pile is uniformly stressed in the hoisting process in a manner that the centers of a plurality of connecting devices are symmetrical and the lengths of the plurality of lifting ropes are equal, the central axis of the tubular pile and the ground are always kept in a vertical state, the device is beneficial to aligning the previous tubular pile to be installed at an installation position, the defects that the traditional steel wire rope is easy to cause accidents in hoisting and the installation efficiency is low are overcome, and the construction efficiency is greatly improved.
