An energy-saving bundled combined hammer

Abstract

The invention provides an energy-saving bundled combined hammer, which includes a connecting square head, a main air intake pipe, an air intake chamber, a gas distribution pipe, a main exhaust pipe, an exhaust chamber, a connecting joint, branches of the exhaust pipe, a cylinder body, and an impactor ; The connecting square head, the air intake chamber, the exhaust chamber, and the cylinder body are fixed sequentially from top to bottom, and a plurality of connection joints are arranged on the top of the cylinder body and the side of the exhaust chamber, and an impactor is installed at the bottom of the cylinder body; The connecting square head is connected to the air intake chamber through the main air intake pipe, the air intake chamber is connected to the connecting joint through the air distribution pipe, and the connecting joint is connected to the impactor; the impactor is also connected to the exhaust chamber through the branch of the exhaust pipe, and the exhaust air The air chamber is provided with a main exhaust pipe. The air consumption of the present invention is reduced, and at least two-fifths of the air volume can be saved under the same conditions; the hole forming efficiency is high, and the back pressure at the bottom of the hole is small, thereby avoiding the problem of low work efficiency caused by excessive back pressure; the comprehensive cost is low; Artificial labor intensity.

Description

technical field [0001] The invention relates to an energy-saving bundled combined hammer, which belongs to the technical field of drilling engineering. Background technique [0002] In some pile foundation hard rock hole-forming projects, the common forming method is rotary drilling. The efficiency of rotary drilling for hole formation is unparalleled for soil, soft rock and overburden, but in hard rock formation, its efficiency is very low, and the drilling tool wears a lot, and the comprehensive construction cost is high. With the continuous development of drilling engineering, the use of the high efficiency of pneumatic DTH hammer to impact holes to achieve hard rock crushing has been widely used in exploration, hydrology and other industries. However, in some large-diameter pile foundation projects, the construction of large-diameter impactors or bundled combined hammers is still in a relatively early stage of development in China. The main reason is that the required a...

However, in some large-diameter pile foundation projects, the construction of large-diameter impactors or bundled combined hammers is still in a relatively early stage of development in China. The main reason is that the required air consumption is too large and the overall cost is too high , the construction boss finds it hard to accept
