Problems solved by technology
The rotating mechanism adopting this structure is because the rotating platform is directly arranged on the rotating shaft and supported by the rotating shaft, and the rotating platform is movable. Even if the upper roof pillar is used to support the roof of the coal mine roadway, the rotating platform is still unavoidable during drilling operations. The rotation will not only affect the drilling accuracy, but also easily cause the drill pipe to be stuck, and even cause the drill pipe to break

Embodiment Construction
[0013] As shown in the figure, a multi-directional hydraulic drilling rig with a floating rotating device includes a traveling device 1, a rotating mechanism 2, a drilling mechanism 3 and a hydraulic pump station. The rotating mechanism 2 is arranged on the walking device 1, and the drilling mechanism 3 is arranged on the rotating mechanism 2, and the drilling mechanism 3 is driven by the rotating mechanism 2 to rotate on the traveling device 1 to adjust the drilling direction. The rotating mechanism 2 includes a floating bottom plate 4 , a rotating platform 5 and a supporting spring 6 . The supporting spring 6 is fixed on the running device 1 , and the floating bottom plate 4 is arranged on the running device 1 through the supporting spring 6 and is supported by the supporting spring 6 . A turntable bearing 7 is provided between the floating bottom plate 4 and the rotary platform 5 , and the rotary platform 5 is supported by the turntable bearing 7 so as to rotate on the floa...

The invention provides a multidirectional hydraulic drill rig with a floating rotary device and relates to a drill rig for extracting and draining mine gas. The multidirectional hydraulic drill rig with the floating rotary device comprises a walking device, a rotary mechanism, a drilling mechanism and a hydraulic pump station, wherein the rotary mechanism is arranged on the walking device; the drilling mechanism is arranged on the rotary mechanism; the rotary mechanism comprises a floating base plate, a rotary platform and a supporting spring; the floating base plate is arranged on the walking device through the supporting spring; a turnplate bearing is arranged between the floating base plate and the rotary platform; a supporting table fixed on the walking device is arranged below the rotary platform; and a top plate telescopic supporting post is arranged on the rotary platform. During drilling, the top plate telescopic supporting post and the supporting table clamp and fix the rotary platform to keep the rotary platform stable and guarantee the drilling precision. By arranging transmission teeth on the outer ring of the turnplate bearing, a transmission gear of a driving motor is engaged with the transmission teeth, so the rotary direction is convenient to adjust.
Description
technical field [0001] The invention relates to a drill truck for coal mine gas drainage, in particular to a multi-directional hydraulic drill truck with a floating rotating device. Background technique [0002] In order to eliminate the hidden dangers of water seepage and gas accidents in coal mines, ensure the safety of coal mine production, and prevent major accidents caused by water seepage and gas outbursts, the state has made the work of preventing water seepage and gas outbursts in coal mines mandatory measures. Gas drainage and long-distance water detection are fundamental measures to control coal mine gas and water seepage accidents. In order to realize multi-directional drilling operations, a rotary mechanism is generally provided on the drill truck, and the drilling mechanism is arranged on the rotary mechanism so as to adjust the drilling direction. The rotating mechanism used in existing drilling rigs is generally equipped with a rotating platform on the ro...
