Hydraulic rotary drilling machine

Abstract

The invention discloses a rhinestone rotary drilling machine. The rhinestone rotary drilling machine comprises a drive device, a pressurizing device, a worktable, a stand column, a drill stem, a rotary power head and a rhinestone drill bit, wherein the stand column is installed on the worktable, the drill stem is installed on the stand column, the upper end of the drill stem is connected with the pressurizing device, and the downward pressure is obtained under the effect of the pressurizing device; the hydraulic drill bit is installed on the lower end of the drill stem, a water inlet is formed in the drill stem, a hollow water passage is respectively formed in the drill stem and the hydraulic drill bit, and a water outlet is formed in the rhinestone drill bit; the drill stem is also connected with the rotary power head and can rotate under the effect of the rotary power head. The stand column is provided with a movable table track and a drill stem movable table, a lever structure is formed in conjunction with the turning of a duplex chain wheel on the lower end of the stand column, the duplex chain wheel is used as a node, the weight of an entire car can be applied to the drill stem movable table, and the sufficient downward pressure can be applied to the drill stem and the rhinestone drill bit by virtue of the drill stem movable table, so that the rhinestone rotary drilling machine can rapidly and efficiently drill a hole in a deep diving manner in complicated soil, and a dual purpose can be realized.

Description

technical field [0001] The invention relates to a piling machine, in particular to a water drilling rotary excavator. Background technique [0002] Rotary drilling rig, also known as "rotary bucket drilling rig", Astley drilling rig, etc., is a large-diameter deep hole forming equipment. Because the "rotary bucket" or "rotary bucket" is used to fetch soil while the square or round telescopic drill pipe with sword is used to increase the drilling depth, it is called "rotary drilling rig" or "rotary bucket drilling rig". At present, there are two most common types of rotary drilling rigs on the construction site: one is an attached type modified by a crawler crane, and the other is an excavator-like excavator and a chassis that is completely imitated after being imported from abroad. The trapezoidal linkage mechanism and the hydraulic cylinder work together to adjust the full hydraulic type of the verticality of the drill pipe. In recent years, the full hydraulic type has de...

Problems solved by technology

Therefore, the traditional digging rig has many defects as follows: 1. When the drill rod is folded and lies flat, the wire rope is easy to loosen and fall off; 2. The self-weight of the drill bit is insufficient. Insufficient; 3. The helical blade on the drill bit is longer, and when it is rotated downward, the frictional force it receives is large, which makes the power consumption of the whole machine large

At the same time, a problem that cannot be ignored is that most of the widely used rotary drilling rigs today are "dry" rotary drilling, and dry drilling rotary drilling is carried out under complex geology. Therefore, in various construction occasions, the rotary drilling effect of the rotary drilling rig with the water drill bit is far better than that of the "dry" rotary drilling rig, but because the rotary drilling rig has a complex structure and a large volume, it is difficult to replace it. Rhinestone drill bits are very difficult and extremely inconvenient in application. There are problems such as large size, high energy consumption, complex structure, and high cost.

On the other hand, the special-purpose water drilling rig is a special equipment without mobility, and often needs to be hoisted to the construction site. The installation and operation are complicated, and limited by its structure, the pressure is mainly applied directly by hydraulic pressure, and the volume is limited during construction. Due to the limitation of hydraulic press power, its construction efficiency is low, but if the volume and hydraulic press power are increased, it will bring higher costs, and it will further aggravate the inconvenience of construction due to volume and weight problems. Too deep column hole rotary drilling, drilling speed is slow, time-consuming and labor-intensive
