At the same time, the working safety and stability of drilling equipment also directly affect the progress of the project
[0003] For drilling in some occasions, drilling equipment needs to splice drill pipes, and chucks are generally used to clamp the drill pipes when splicing. The chucks on both sides of a drill pipe are driven by different hydraulic cylinders, which is prone to clamping on both sides. If the clamping degree of the head is not synchronized, it is also easy to cause the drill pipe to deviate after work, which is not conducive to the long-term stable work of the drill pipe

The invention relates to an engineering drilling device. The engineering drilling device comprises a connecting base, a clamping assembly, an advancing assembly, a rotating assembly and a drill rod, wherein the rotating assembly is arranged on the advancing assembly, the advancing assembly is arranged on the connecting base, and the advancing assembly can move in the length direction of the connecting base; the drill rod is detachably arranged on the rotating assembly and can be driven by the rotating assembly to rotate; the clamping assembly comprises a hydraulic oil cylinder and two or more sets of hydraulic clamping heads, the two sets of hydraulic clamping heads are both connected with the hydraulic oil cylinder, the hydraulic clamping heads are driven by the hydraulic oil cylinder to be opened and closed synchronously, and the hydraulic clamping heads are uniformly arranged on the axial connecting base of the drill rod. According to the engineering drilling device, clamping parts can be opened and closed synchronously, the problems that drill rod clamping is not stable, and deviation is prone to occurring in the construction process due to the fact that clamping equipment at the clamping position of the drill rod works inharmoniously are solved, and the drilling operation quality is improved.
Description
technical field [0001] The invention relates to the technical field of engineering equipment, in particular to an engineering drilling device. Background technique [0002] Infrastructure construction is inseparable from rammed foundations, directional blasting, soil anchoring and other engineering content. Among them, soil anchoring is a technology that uses reinforced cement columns to drill holes into rock layers and soil to strengthen rock and soil slopes. Due to the complex terrain of the construction site and the harsh working environment, the stability requirements for drilling equipment or devices are relatively high. At the same time, the working safety and stability of drilling equipment also directly affect the progress of the project. [0003] For drilling in some occasions, drilling equipment needs to splice drill pipes, and chucks are generally used to clamp the drill pipes when splicing. The chucks on both sides of a drill pipe are driven by different hydraul...
