Abstract

The invention discloses a universal rotary drilling rig capable of walking. The universal rotary drilling rig capable of walking comprises a chassis arranged on a walking mechanism and a universal gyration device. The universal gyration device comprises a first gyrator device, a two-way lifting oil cylinder and a second gyrator device. A fixed part of the first gyrator device is fixed to the chassis and a rotary axis of a rotary part is perpendicular to the chassis. The two-way lifting oil cylinder comprises a first cavity and a second cavity which are formed in the length direction of a cylinder body. A first piston is matched with the first cavity. The two ends of a first piston rod are connected with the first piston and the rotary part of the first gyrator device respectively. A second piston is matched with the second cavity. One end of a second piston rod is connected with the second piston and the other end of the second piston rod extends out of the second cavity. A fixed part of the second gyrator device is arranged on the cylinder body of the two-way lifting oil cylinder and a rotary part is fixedly connected with a main drilling rig body. By the adoption of the universal rotary drilling rig capable of walking, the drilling direction is adjusted from -180 degrees to 180 degrees in both the horizontal plane and the vertical plane, so that the drilling rig meets the drilling requirements of different heights and different angles.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a movable universal rotary drilling rig. Background technique [0002] During the mining process of underground coal mines, due to the complex and changeable coal seam occurrence conditions, major gas accidents often occur. Therefore, in order to prevent local gas safety accidents in coal mines and achieve effective gas extraction and utilization, it is necessary to use drainage drilling rigs for detection before excavation. holes to detect and utilize the gas in the mine to avoid gas explosion accidents. [0003] In the prior art, there are many types of gas drainage drilling rigs used in underground mines, generally consisting of three parts: main engine, pumping station, and console. Please refer to figure 1 , figure 1 It is a structural schematic diagram of a four-column underframe drilling rig in the prior art. The four-column underframe drilling rig in the prior art...
