Drilling machine

Abstract

The invention discloses a drilling machine which comprises a crawler walking part, a platform, a control system arranged on the platform, a horizontal gyrator, a stand column, a vertical gyrator, a power head steering device and a main machine assembly. The power head rotating device comprises a bracket and a rotating device arranged on the bracket and used for steering and turning around the main machine assembly. The bracket is connected with a rotating disc of the vertical gyrator, the outer side of the rotation device is hinged to the bracket, and the main machine assembly is arranged on the rotation device. A lifting device is further arranged between the rotating device and the bracket and drives the rotating device to rotate with the hinged position of the rotating device and the bracket as a fulcrum. When steering and turning are needed, the lifting device jacks up to form an included angle between the rotating device and the bracket, and then the rotating device drives the main machine assembly to jointly rotate to the reverse position so as to achieve steering and turning of the main machine assembly. According to the drilling machine, the drilling machine main machine can still be located above the supporting rail after turning around by 180 degrees, and rapidness and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a drilling rig. Background technique [0002] Drilling rigs are widely used for underground drilling in coal mines. In order to realize multi-angle tunneling, the drilling machine in the prior art uses multiple sets of rotating parts to adjust the position. For example, a hydraulic 360° space spherical all-round tunnel for coal mines disclosed in patent CN205330538U Drilling rig can realize multi-directional drilling. For example, with the attached image 3 For the first drilling work position, now the drilling rig is drilling to the left side, and now the drilling actuators including the power head 30 on the main engine are all above the support rails. When it is necessary to drill on the right side of the drilling rig, by rotating the second turning mechanism on the side of the main machine clockwise or counterclockwise by 180 degrees, the power head can be turned to car...

Problems solved by technology

But, the problem that exists is mainly: because rotated 180 degrees, now the executive mechanism including power head 30 as a whole is positioned at the below of its support track, that is to say, this time the whole power head is suspended on the positive side of the support structure. Below, the gravity of the power head plus the impact force during work is obviously detrimental to the stability and safety of the drilling rig

In addition, in the prior art, the power head and other components on the support rail are first removed from the support rail, and then reversed and reinstalled to realize the steering. This method is not only time-consuming and laborious, but also difficult It cannot be completed, and it is necessary to move the drilling rig to a specific place and use special hoisting equipment to complete it. Therefore, it is also subject to many restrictions
