Examples

As shown in fig. 3 and 4, the pile construction equipment provided by the present embodiment includes a lifting head 60 and a pile connecting device, and the pile connecting device is fixed to the lifting head 60.

Generally, the pile construction equipment further includes an excavator, the pile connecting device is installed at one end of the pile 70 far from the ground, and then connected to the excavator through the hoisting head 60, the pile 70 is hoisted by the excavator, and the construction operation of the pile 70 is performed. That is to say, the excavator exerts the effort to pile body 70 through lifting head 60 and pile body connecting device to through producing the supporting role to the one end that pile body 70 keeps away from ground, and then ensure that pile body 70 can not be because of the unstable inclined pile of ground atress when meetting soft soil foundation in the work progress, improve the stability of pile body 70 construction, reduce the potential safety hazard. In addition, after the pile body connecting device is fixed relative to the pile body 70, the pile body 70 cannot incline when being constructed at a soft soil foundation, so that soil adding and backfilling are not needed for multiple times, the operation process is simplified, and the construction period is effectively shortened. The following is a concrete explanation of the pile connecting device.

As shown in fig. 1 and 2, the pile connecting device provided by the embodiment comprises a clamping assembly 10 and a fixing assembly 20; the fixing assembly 20 is used for being connected with the lifting head 60, the clamping assembly 10 is installed on the fixing assembly 20, the clamping assembly 10 comprises a first clamping arm 11 and a second clamping arm 12, the first clamping arm 11 and the second clamping arm 12 are arranged oppositely and at intervals, a clamping space 13 is arranged between the first clamping arm 11 and the second clamping arm 12, and the pile body 70 can be inserted into the clamping space 13; the first clamping arm 11 can move relative to the fixed assembly 20 to clamp or release the stub body 70 located in the clamping space 13.

Specifically, the clamping assembly 10 is mainly used for contacting with the end of the pile body 70 and can be fixed relative to the pile body 70, so that the purpose of installing the pile body connecting device relative to the end of the pile body is achieved, one end of the pile body 70, which is far away from the ground, is supported, and it is ensured that the pile body 70 is not prone to pile deflection in the construction process. The fixing assembly 20 is used for fixedly connecting with the hoisting head 60, so as to achieve the purpose of installing the pile body connecting device relative to the hoisting head 60. The clamping assembly 10 includes a first clamping arm 11 and a second clamping arm 12 which are arranged oppositely and at an interval, a clamping space 13 is formed between the first clamping arm 11 and the second clamping arm 12, and an end of the pile 70 is inserted into the clamping space 13. At this time, the first clamping arm 11 moves relative to the fixing assembly 20, so that the first clamping arm 11 can gradually approach to the second clamping arm 12, the clamping space 13 between the first clamping arm 11 and the second clamping arm 12 is gradually reduced, and the pile body 70 located in the clamping space 13 is clamped by the first clamping arm 11 and the second clamping arm 12, so that the clamping assembly 10 is installed relative to the pile body 70. When the pile driving operation is completed, the first clamping arm 11 moves in the opposite direction, i.e. moves away from the second clamping arm 12, the clamping space 13 gradually increases, so as to loosen the pile body 70 located in the clamping space 13, and the clamping assembly 10 is removed from the pile body 70, so as to remove the pile body connecting device from the pile body 70.

This pile body connecting device presss from both sides tight pile body 70 through first joint arm 11 and second joint arm 12, realizes the fixed of the relative pile body 70 of joint subassembly 10, keeps away from the one end on ground through this pile body connecting device and pile body 70 promptly and is connected, realizes fixing the relative ground of pile body 70, ensures in the soft soil foundation when constructing pile body 70, and pile body 70 can not incline because of the soft soil foundation, reduces the potential safety hazard.

It should be added that, not only the first snap-in arm 11 moves relative to the fixed component 20, but also only the second snap-in arm 12 moves relative to the fixed component 20, that is, the second snap-in arm 12 moves closer to and away from the first snap-in arm 11. Or the first and second snap arms 11 and 12 move simultaneously relative to the fixed component 20, i.e. the first and second snap arms 11 and 12 move simultaneously towards each other and can move simultaneously away from each other.
