Problems solved by technology

But both of them also have the following problems: the noise source is high; although pile caps and pile pads are added, it is common for the pile head to crack, and the bearing capacity of the pile body and the corrosion of the reinforcement are unavoidable; The body is an elastic system. When the weight falls on the top of the pile, the positive half wave of the vibration wave points to the pile tip, and the negative half wave points to the pile top, which is a tensile stress for the pile body.

Embodiment Construction

[0034] see figure 1 , is a schematic diagram of the top-pull hydraulic power pile driving machine of the present invention, which mainly includes a power chamber 2 fixed in the main frame 1, the power chamber 2 is a square long cylinder, and an openable and closable The door is used for hanging piles. The power chamber 2 is provided with an impact body 3, a compressed tension box 4, an impact regulator 5, a penetration detection device, etc., and a guide frame 7 is installed on the top of the power chamber 2 to guide There are pull rods 6 on both sides of the frame 7, a pile cap 9 with a tongue 8 and a lifting translation mechanism in the middle, and a lifting leg 10 is set on the main frame 1, most of which have been outlined in Chinese patents 200620052177.7 and 200920064321.2 , which will not be described in detail here, and the improvements of the present invention will be described below.

[0035] Such as figure 2 As shown, the lifting cylinder 11 is changed from the ...

Abstract

The invention relates to a push-pull-type hydraulic power pile-sinking machine. Based on the prior art, by researching a control system, the invention further improves the structures of a power chamber frame, an impact body and an attacking tension-compression box, lifts the position of an oil cylinder, sets an automatic leveling system on a pile machine main frame and integrates all links into a whole so that the technology is more advanced, the theory is more perfect and the using is safer. According to the relay control system, a ladder diagram language can be conveniently programmed for laying a ground for a programmable logic controller (PLC).

Description

Technical field: [0001] The invention relates to a construction engineering machine (pile machine for short) for foundation construction in the construction industry, in particular to a top-pull hydraulic power pile driving machine. Background technique: [0002] Pile machinery is a big family, and only hammer pile machines are described here. In 1936, the Germans invented the diesel hammer. After more than 30 years of application and development, because of its noise pollution, it is no longer acceptable to the people, and the requirements for remodeling continue to attract the attention of various countries. In 1972, the Dutch HBM company invented the hydraulic hammer, the noise was reduced to 75dB, and it was soon promoted to countries all over the world. Our country has gone another way. In 1978, Wuhan Construction Machinery Factory developed the 80t hydraulic static pile driver. In 31 years, it has grown from small to large and expanded throughout the country. However...
