Full-automatic hydraulic pile breaker

Abstract

The invention discloses a full-automatic hydraulic pile breaker and relates to a pile foundation machine for constructional engineering. A hydraulic system of the pile breaker is controlled through a closed-loop technology, the pile breaker is quick in response and high in sensitivity, a human-machine interface is arranged, an error correction function is provided, and operators can see the whole process of pile breaking of the pile breaker clearly in a display screen of the human-machine interface. A working principle that a pile body is extruded from different points of the same end face simultaneously is used for breaking a pile head, and the large-scale pile breaking requirement is met. The pile breaker is advanced in technology, convenient to operate, safe, stable in performance, high in working efficiency, capable of reducing the labor intensity of workers and saving energy, low in construction noise, environmental friendly and long in service life. The plane of a pile top is flat after the pile head is broken by the pile breaker, the broken pile head is good in appearance quality, the construction quality can be guaranteed, and the safety and the health of constructors are benefited.

Description

technical field [0001] The invention relates to a pile foundation machine for construction engineering, in particular to a fully automatic hydraulic pile cutter. It can be easily connected with a variety of construction machinery, and the product has a wide range of applications. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of my country's current industrial development. my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. In the process of pile foundation construction, for the convenience of construction, the manufactured piles will be longer than the actual ones, but after driving (or other processes) to the design depth, the excess part above the bottom surface of the foundation must be cut off. pile. At present, the traditional method o...

AI Technical Summary

Problems solved by technology

At present, the traditional method of breaking pile heads in China is manually using pneumatic picks to break the pile heads. During the construction period, the noise, vibration and dust are relatively large. Causes certain noise pollution, cannot meet the requirements of large-scale pile cutting, low efficiency and high cost

Moreover, this method is easy to cause cracks in the removed pile head, and the surface of the removed pile head is not smooth, which is not conducive to subsequent construction, and also affects the construction progress.

Also use another method hydraulic air hammer to cut off the pile head, when cutting off the pile head, it will damage the integrity of the pile body and affect the strength of the pile body; there is also a portable cutting machine to cut the pile head, cutting will damage the steel bar, After the cutting is completed, the large pile heads are relatively heavy, and it is difficult to transport them out of the foundation pit, which may cause injury to workers
