Multi-wedge-surface drill rod and drill rod automatic assembling and disassembling equipment applied to same

Abstract

The invention discloses a multi-wedge-surface drill rod. The multi-wedge-surface drill rod comprises a rod body, a connecting head, a connecting tail, a locking wedge block and a locking nut, whereinthe connecting head and the connecting tail are connected to the two ends of the rod body, the connecting head is provided with an axial rectangular pyramid table, the connecting tail is provided witha rectangular pyramid hollow, and a synchronous pulley is arranged on the outer circle surface of the locking nut. Through coaxial matching of the rectangular pyramid table and the rectangular pyramid hollow, the drill rod can be rapidly assembled and disassembled, and the advantages of being large in bearing torque, long in service life, easy to disassemble, low in cost and the like are achieved. Drill rod automatic assembling and disassembling equipment applied to the multi-wedge-surface drill rod is arranged on one side of a drilling machine and comprises a locking nut assembling and disassembling mechanism, a locking wedge block assembling and disassembling mechanism, a drill rod assembling and disassembling mechanism and a control system. According to the drill rod automatic assembling and disassembling equipment, the automation degree is high, automatic assembling and disassembling of the drill rod are realized, the labor intensity of operators is greatly reduced, and the working efficiency is improved; and a drill rod circulation box of the drill rod automatic assembling and disassembling equipment is large in capacity, and the problems of placing, carrying and transportingof the drill rod are solved at the same time.

Description

technical field [0001] The invention relates to the fields of tunnels, bridges and mining equipment, in particular to a multi-wedge drill pipe and its automatic loading and unloading equipment. Background technique [0002] The drilling rig needs to continuously add drill pipes during work to achieve drilling depth. When adding drill pipes, the connecting head of the newly added drill pipe is connected to the connecting tail of the drill pipe on the drilling rig. The head-to-tail connection of existing drill rods is realized by threaded connection, the connection head is a shaft with external threads, the connection tail is a hole with internal threads, and the connection head and the connection tail are screwed together. In order to ensure that the drill pipe does not fall off in the drill hole, the screwing direction of the thread is consistent with the rotation direction of the drilling rig. In this way, the resistance moment of the drill pipe during work and the torque o...

AI Technical Summary

Problems solved by technology

At the construction site, the drill pipes are usually scattered on both sides of the drilling rig. Manual operation is required when loading and unloading the drill pipes. Every time the drilling rig changes to a construction position, the drill pipes have to be moved once. The operator has a lot of labor. Drill pipe damage is also great

Therefore, there are also big problems in the placement, handling, transportation and management of drill pipes.
