Double-pole multi-degree-of-freedom drilling rig

Abstract

The invention discloses a double-pole multi-degree-of-freedom drilling rig. The rig comprises a seat assembly and a drilling assembly, the seat assembly is provided with the drilling assembly, and theseat assembly has more than two degree-of-freedom adjustment; the drilling assembly is composed of two sets of drills, the two sets of drills are installed side by side on the seat assembly to form adouble-pole structure, each set of drills include drilling rods, slide tables and deviation prevention assemblies, the deviation prevention assemblies include deviation prevention support seats and telescopic rods, the telescopic rods are symmetrically disposed on the two sides of the drilling rods to form combined bodies with the deviation prevention support seats, the tail ends and the front ends of the two telescopic rods are respectively fixedly arranged to prevent deviation when the drilling rods conduct drilling, and the telescopic rods are synchronously driven to gradually contract from back to front when the drilling rods move forward with the deviation prevention support seats as nodes; the degree-of-freedom adjustment of the seat assembly is used for controlling the two sets ofdrills to work together.

Description

technical field [0001] The invention discloses a double-bar multi-degree-of-freedom excavation drilling rig, belongs to the technical field of drilling engineering machinery manufacturing according to the International Patent Classification (IPC), and in particular relates to a drilling rig with multi-freedom adjustment. Background technique [0002] At present, in the process of road construction and quarrying, in consideration of safety and other issues, precise static blasting construction is required, and blast holes need to be drilled. The blast holes are generally completed by jackhammers (hand-held pneumatic drills), which are pneumatic tools. , because the noise when it works is relatively loud like the sound of a cannon, so it gets its name. The power source of the jackhammer is the compressed air output by the air compressor. Manual operation has the disadvantages of low efficiency and shallow drilling depth, and the labor intensity of the operator is very high, an...

Problems solved by technology

However, this drilling rig has only one drill pipe, which can only work forward and backward, which is not suitable for left and right fine-tuning, and the cooperation between the chain and the pulley is more complicated. When the steel wire is working, it is easy to wind the rope, which affects the normal work.
