When a shaft is manufactured by blasting and excavation, it is necessary to carry a rock drill into the shaft during excavation and to excavate a hole for charging explosives. Also, it is usually necessary to drill holes for charging explosives at multiple locations for each blast. However, for example, when the diameter of the shaft to be excavated is as narrow as about 12 m, the conventional rock drilling machine cannot move the rock drilling means inside the shaft. Therefore, in order to excavate holes for charging explosives at a plurality of locations, every time one hole for charging explosives is excavated, it was necessary to carry out the rock drilling machine and then re-import the rock drilling machine. In other words, when a plurality of holes for charging explosives are excavated using a conventional rock drill when the excavation target is narrow, the efficiency of excavating the holes is extremely poor, causing an increase in cost and an extension of the construction period.

And a movable drilling drill jumbo, characterized in that it comprises a turning means for turning the guide means with respect to the main body.

According to the first aspect of the present invention, after the guide means for guiding the rock drilling means back and forth is turned by the turning means, the vertical means, the vertical angle adjusting means and the horizontal angle adjusting means are provided. The rock drilling means and the guide means can be arranged at arbitrary positions and angles by adjusting the angle of the guide means using. Therefore, according to the drilling drill jumbo of the first aspect, a hole at an arbitrary angle can be efficiently drilled at an arbitrary position without moving the position of the drilling jumbo.

For this reason, when a hole for charging explosives is drilled at the bottom of a shaft for blasting and excavation, if the hole drilling jumbo of the present invention is used, even if the diameter of the shaft is small, the hole drill inside the shaft is used. Even if the jumbo cannot be moved, a plurality of explosive charging holes can be drilled without removing the drilling drill jumbo. Therefore, the blasting excavation efficiency of the shaft is improved, and the construction period and cost can be reduced.

Here, as the rock drilling means, for example, a well-known drifter is used. A well-known cell is used as the guide means. The vertical angle adjusting means and the horizontal angle adjusting means include, for example, a model THRQ-EX-L
