Small multifunctional rock drill

Abstract

The invention discloses a small multifunctional rock drill. The small multifunctional rock drill comprises a machine body platform, a longitudinally moving mechanism, a transversely moving mechanism, a lifting mechanism, a mast mechanism, a diagonal brace, a mast lifting oil cylinder, a power head and a drill rod, wherein the machine body platform is connected with the longitudinally moving mechanism and the transversely moving mechanism through the lifting mechanism; one end of the diagonal brace and one end of the mast lifting oil cylinder are both connected with the machine body platform, and the other ends of the diagonal brace and the other end of the mast lifting oil cylinder are connected with the mast mechanism; a main winch, a pressurizing winch, a driving cab, a movable counterweight iron, an electrical control system and a hydraulic control system are arranged on the machine body platform; the mast mechanism is mounted on the machine body platform; the power head is mounted on a mast of the mast mechanism; a steel wire rope of the main winch passes by a pulley bracket at the upper end of the mast of the mast mechanism and is connected with the power head; a steel wire rope of the pressurizing winch is connected with the lower part of the power head through a set of wheel train; a central output shaft of the power head is connected with the drill rod. The small multifunctional rock drill is convenient to lift the mast, and can achieve integral transportation; after the movable counterweight iron is hung, the self weight of the small multifunctional rock drill is large, so that the small multifunctional rock drill can provide relatively high pressure, and is wider in geological adaptability.

Description

technical field [0001] The invention belongs to the technical field of drilling rigs, and in particular relates to a small multifunctional rock drilling rig capable of realizing long spiral construction. Background technique [0002] Wanchang high-rise buildings rise from the ground, and pile foundation construction is an important process in building construction. The long auger drilling method used by the long auger drilling rig is a technique widely used in pile foundation construction. The long helical drilling is carried out by continuous cutting and conveying to take soil and form holes, and its construction efficiency is higher than that of other cast-in-situ pile construction machines. [0003] But for a long time, traditional long auger drilling machines have used electric power heads, which generally provide little torque, and are pressurized by the power head’s own weight, without a pressure device, so the geological adaptability and rock penetration ability are ...

AI Technical Summary

Problems solved by technology

However, this type of machine is basically a large-scale machine, the drillable hole is deep, the whole machine is huge, it is inconvenient to assemble and disassemble, and the purchase cost is relatively high

For construction sites where the hole depth is not required but the geology is relatively hard, if such a large-scale machine is used for construction, the construction cost will be virtually increased.

[0005] There are also some small long auger drilling machines on the market, which are light in weight and use an electric power head to drive the drill pipe. The power head is pressurized by its own weight, which is basically only suitable for some softer geological conditions.
