Deflection-swinging type semi-automatic rod replacing hydraulic rock drilling machine

Abstract

The invention relates to a deflection-swinging type semi-automatic rod replacing hydraulic rock drilling machine. The machine comprises a carrier machine, a movable arm and a drilling machine body. One end of the movable arm is arranged at the upper end of the carrier machine, and the other end of the movable arm is connected with the middle of the drilling machine body. The movable arm drives the drilling machine body to swing in a deflected mode. Compared with the prior art, drill rod replacing is convenient, potential safety hazards are reduced, the directions for deflection swinging of the drilling machine are increased, and drilling precision is improved.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a tilting type semi-automatic rod changing hydraulic rock drill. Background technique [0002] The current hydraulic rock drilling rigs mainly have the following problems: [0003] (1) Existing hydraulic rock drilling rigs have two ways to change rods, one is full manual rod changing, and the other is fully automatic rod changing. [0004] Full manual rod replacement is the complete use of manual unloading and connecting rods. It usually requires 2 to 3 people to cooperate to complete it. When the drill rod is manually jammed for disassembly, it is easy to slip due to insufficient clamping force, and it is difficult to unload the rod. Cause personal injury, high risk factor, laborious manual operation, high labor intensity, and low work efficiency. [0005] Fully automatic rod changing usually includes a series of devices such as upper manipulator, lower manipulator, upper r...

AI Technical Summary

Problems solved by technology

The structure is very complex, the requirements for the hydraulic control system and the electric control system are very high, the manufacturing precision is high, the manufacturing and maintenance costs are high, and the working conditions of the drilling rig are harsh, the vibration is large, and the reliability of the rod changing mechanism is poor.

[0006] (2) The drill arm of the existing hydraulic rock drilling rig usually does not have a yaw structure, and can only swing back and forth, and cannot yaw left and right

When the drilling rig stops on the horizontal slope and drills holes, the verticality of the drill pipe and the surface cannot be guaranteed, resulting in the phenomenon of drilling inclined holes; sometimes it is even impossible to drill due to the influence of the working terrain

In order to achieve yaw, some need to be equipped with a special yaw beam and connected to the drill boom. The yaw beam itself has a complex structure and a large size, which increases the mass of the machine, the grounding pressure of the whole machine is large, the use is limited, and the production cost high

At the same time, the connecting pin shaft is prone to wear and tear due to the large force, causing the drill arm to fall off, causing serious losses and even endangering personal safety.
