Description

Asynchronous rotating device for inclination angle adjustment of drilling machine Technical Field The utility model belongs to the field of mining drilling rigs, and relates to an asynchronous rotating device for adjusting inclination angles of a drilling rig Background Under the large background of coal mine intelligent development strategy, drilling machine automation becomes a key core means for pushing underground operation to be changed to few humanization and no humanization. In the traditional coal mining mode of operation, rig operations are primarily manually accomplished. However, the underground working environment is extremely complex, various uncertain factors such as potential hazards of gas, coal dust and the like exist, and meanwhile, operators are in a working state with high strength and high risk for a long time, so that fatigue is extremely easy to generate. The traditional manual operation mode is doubly limited by underground complex environments and personnel fatigue degrees, and is difficult to meet the double requirements of efficient mining and intrinsic safety assurance of modern coal mines. On one hand, the manual operation efficiency is limited, quick and accurate drilling operation is difficult to realize, the improvement of the coal mining efficiency is restricted, and on the other hand, personnel operate in a complex dangerous environment, the safety risk is high, and once accidents occur, the consequences are not considered. The advent of automation technology provides an effective way to solve the above-mentioned problems. By applying automation techniques, the drilling process of the drilling machine and the associated auxiliary processes can be automated. The labor intensity of operators is remarkably reduced, and the exposure time of the operators in a dangerous area is reduced, so that the operation safety is greatly improved, the efficiency bottleneck of manual operation is broken through, and the coal mining operation is more efficient and stable. Therefore, automated drilling rig technology is a necessary choice for technology upgrades in the coal industry. Through the development of the last ten years, the automatic drilling machine technology is greatly improved and matured day by day. At present, an automatic drilling machine can realize full-automatic operation of key procedures such as drilling rod loading and unloading, drilling, gesture adjustment and the like, is applied to large-scale coal mine disaster prevention and control engineering such as gas extraction, water exploration and drainage and the like, and provides powerful guarantee for coal mine safety production. However, there are still some problems to be solved in the existing automatic drilling machine technology. Taking a certain automatic drilling machine (application number: CN 201911185745.9) applied in the industry as an example, the inclination angle design of the drill rod transporter has defects, and the drill rod transporter cannot be correspondingly adjusted along with the change of the inclination angle of the rack, and can only be completely dependent on the drill rod conveying mechanical arm to adjust the drill rod conveying inclination angle. More critical is that the layout of the drill rod transporter and the drill rod conveying manipulator and the frame in the prior art is unreasonable, the drill rod transporter and the drill rod conveying manipulator are arranged on the same side of a lifting sleeve (the name of the lifting frame in CN 201911185745.9), the frame is positioned on the other side of the lifting sleeve, and the transporter and the manipulator are positioned on one side close to the crawler. In the process of inclination adjustment of the drill rod conveying manipulator, particularly under the working condition of a negative inclination angle, the drill rod conveying manipulator, the crawler and the drill rod transporter inevitably generate interference phenomenon. The technical problem causes that the existing automatic drilling machine cannot construct the negative large-inclination-angle drilling, so that the pushing of the comprehensive intelligent construction of the coal mine is limited to a certain extent, and the application of the automatic drilling machine technology in wider scenes is also restricted. Disclosure of utility model Therefore, the utility model aims to provide an asynchronous rotation device for adjusting the inclination angle of a drilling machine, so as to solve the problem that the inclination angle of the drilling machine is smaller due to the fact that a drill rod transporter cannot adjust the inclination angle by a random frame. In order to achieve the above purpose, the present invention provides the following technical solutions: An asynchronous rotary device for inclination adjustment of a drilling machine, comprising: A lifting sleeve as a carrier for the asynchronous rotation device; The lifting oil cylinder is used for vertically lif
