Vibrating type power head device

Abstract

The invention discloses a vibrating power head device, which comprises a vibrating assembly and an outer box arranged outside the vibrating assembly, a guiding mechanism is arranged between the vibrating assembly and the outer box, the vibrating assembly includes a vibrating box and a gear box, and the front end of the gear box The drilling tool is connected through the output joint, and the vibration box is detachably connected at the rear end. In the present invention, a vibration box and a gear box are arranged in the outer box. Through the fixed connection between the vibration box and the gear box, the vibration box directly drives the gear box and the main shaft to vibrate together, thereby driving the drilling tool to vibrate and rotate the drilling at the same time, which can effectively reduce the vibration of the main shaft. The damage received makes the vibration transmission route more reasonable. Moreover, the vibration box and the gear box ensure that the vibration displacement of the vibration component only occurs in the axial direction through the guiding mechanism, and limit the unreasonable vibration in other directions, so that the generation and transmission of the exciting force are stable and reliable, and the impact direction is consistent. Improve the work efficiency of drilling holes.

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...
