Pile driver

Abstract

The invention relates to a pile driver which comprises a main platform, wherein the main platform is used for installing pile lifting and pile driving equipment, and a supporting structure is arrangedat the bottom of the main platform. The pile lifting and pile driving equipment comprises a walking platform and a revolving platform. The pile lifting and pile driving equipment is characterized inthat the walking platform is arranged on the main platform, can slide in the length direction of the main platform and can be located, the revolving platform is arranged on the walking platform in a rotary mode and can perform 360-degree rotation relative to the walking platform, a control cabinet and lifting equipment for lifting concrete piles and hydraulic pile hammers are arranged on the revolving platform, a manipulator device which can be opened and closed is arranged at the front part of the revolving platform, the manipulator device can hold the lifted concrete piles after being closed, and the manipulator device can rotate along the revolving platform. As the manipulator device can hold the lifted concrete piles after being closed and the manipulator device can rotate along the revolving platform, the concrete piles cannot shake in a pile lifting process, and the piles can be more quickly lifted to be in place; thus, a pile driving efficiency is greatly improved.

Description

technical field [0001] The invention relates to a river, lake and river coast embankment project, in particular to a pile driver used for piling construction of the river, lake and river coast embankment project. Background technique [0002] In current river and lake embankment projects, when concrete piles and other components are used to construct embankment protection walls, piling construction needs to be carried out on the embankment of rivers, lakes and seas. In practice, the piling guide equipment often used in embankment construction is simple and rectangular Frame structure, during the construction operation, the frame structure is first set on the fixed member at the starting point of the project, then the piles are inserted into the frame structure and driven into the soil, and then the adjacent piles are driven side by side into the soil for splicing However, when using this frame structure-guided piling construction, the single pile body is easy to deviate from...

AI Technical Summary

Problems solved by technology

[0005] During the pile-hanging process of this walking-type pile driver, due to the rotation of the rotary platform, the lifted concrete piles are easy to shake and are very unstable. Hanging piles takes a long time

[0006] In addition, when this walking pile driver is working, it is necessary to pre-pile many concrete piles to be piled on the original bank. location, the weight of a single concrete pile is already very heavy, if multiple concrete piles are piled up near the edge of the original bank at the same time, the construction of the new embankment is not completed, and the old embankment is likely to be damaged here. In some cases, the cost of repairing the damaged embankment is often greater than the cost of building a new revetment, and the gain outweighs the gain

If damage is caused to the ancient embankment, there is a possibility that it cannot be repaired

In addition, the existing walking mechanism mostly adopts chain or linear bearing structure. Such a mechanism walks in the river, and the sand or small stones in the river can easily block the chain or linear bearing, resulting in the failure of the walking mechanism.

[0007] When revetment construction is carried out in a river channel with a stepped embankment with an upper embankment and a lower embankment, it is not suitable to pile concrete piles and walk on the lower embankment because the lower embankment may be submerged in water and the strength of the lower embankment is not enough. Engineering vehicles, that is to say, concrete piles are only suitable for stacking on the upper embankment, but the walking pile driver in the river is far away from the upper embankment, and the pile driver cannot lift the concrete piles placed on the upper embankment, so the existing Pedestrian pile drivers are not suitable for construction in river channels with specific upper and lower embankments
