Vibrating type power head device

Abstract

The invention discloses a vibrating type power head device which includes a vibration assembly and an external box which is arranged outside of the vibration assembly; a guiding mechanism is arrangedbetween the vibration assembly and the external box; the vibration assembly includes a vibration box and a gear box, the front end of the gear box is connected to a drill tool by the output joint, andthe rear end is detachably connected to the vibration box. The vibration box directly drives the gear box and the spindle to vibrate together; the vibration box and the gear box are fixedly connected, ; thus driving the drill tool to vibrate and rotary drilling simultaneously; the damage of the main axle can effectively reduced when the vibration is vibrated, so that the transmission line of thevibration is more reasonable. Moreover, the vibration box and the gear box can ensure that the vibration assembly only take the axial vibration displacement in the axial direction, but restrict the unreasonable vibration in other directions by the guiding mechanism, so that the generate and transmit of the excitation force is stable and reliable, the impact direction is consistent, and the workingefficiency of drilling is improved.

Description

technical field [0001] The invention relates to the field of drilling equipment for construction engineering, in particular to a vibrating power head device. Background technique [0002] The power head is one of the important parts of the engineering drilling rig. The power head provides torque for the rotary motion of the drilling tool. At present, the drilling tool and the alloy drill bit are usually used to drill into the soil layer. However, in the actual use process, if the rock For the construction of the formation, the construction efficiency of the alloy drill bit with only rotary motion is low. The prior art provides a power head device, which uses a vibrating box installed on the connecting plate on the upper part of the gear box through two-way damping springs on both sides. The vibration of the main shaft in the machine is coordinated, and the main shaft is directly driven to vibrate. This kind of power head device directly drives the main shaft to vibrate thr...
