Abstract

A drilling rig with a rotatable column of the utility model includes a crawler car body, a column is vertically arranged on the top of the crawler car body, a guide rail is arranged horizontally on the column, and a power head is arranged on the guide rail. A slewing reducer with a slewing bearing is vertically arranged on the top of the tracked car body, and the slewing bearing includes an outer race and an inner race that can rotate relatively under the drive of the slewing reducer. The outer race and the track The type car body is connected by bolts, and the bottom end of the column penetrates into the inner race and is connected with the inner race by bolts. The beneficial effects of the utility model are: the rotation of the column is realized by adding a rotary reducer, so that the power head can be adjusted at an angle of 360 degrees in the horizontal direction, and the construction efficiency is greatly improved.

Description

A drilling rig with a rotatable column

technical field

The utility model relates to a drilling machine with a rotatable column.

Background technique

Pneumatic rock bolt rig is a roadway bolt support equipment used in coal mines. It has very prominent advantages in improving the support effect, reducing costs, speeding up roadway formation, reducing auxiliary transportation volume, reducing labor intensity, and improving the utilization rate of roadway sections. . At present, the columns of domestic similar pneumatic drilling rigs are generally fixed on walking parts such as crawler belts, and do not rotate. It is inconvenient to adjust the angle of the horizontal direction of the power head like this, which brings a lot of inconvenience to the construction.

Contents of the invention

In order to solve the above technical deficiencies, the utility model provides a drilling rig with a rotatable upright column which is convenient for adjusting the horizontal angle of the power head.

The utility model is achieved through the following measures:

A drilling rig with a rotatable column of the utility model includes a crawler car body, a column is vertically arranged on the top of the crawler car body, a guide rail is arranged horizontally on the column, and a power head is arranged on the guide rail. A slewing reducer with a slewing bearing is vertically arranged on the top of the tracked car body, and the slewing bearing includes an outer race and an inner race that can rotate relatively under the drive of the slewing reducer. The outer race and the track The type car body is connected by bolts, and the bottom end of the column penetrates into the inner race and is connected with the inner race by bolts.

The above-mentioned guide rail is horizontally connected on the column, and the power head is parallel to the guide rail.

The beneficial effects of the utility model are: The rotation of the column is realized by adding a rotary reducer, so that the power head can be adjusted at an angle of 360 degrees in the horizontal direction, which greatly improves the construction efficiency.

Fig. 2 is a top view structural diagram of the utility model.

Among them: 1 column, 2 guide rail, 3 power head, 4 rotary reducer.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figures 1 and 2, a drilling rig with a rotatable column 1 of the present utility model includes a crawler car body, a column 1 is vertically arranged on the top of the crawler car body, and a guide rail 2 is arranged horizontally on the column 1. The guide rail 2 A power head 3 is arranged on the top, and a slewing reducer 4 with a slewing bearing is vertically arranged on the top of the crawler car body. The slewing bearing includes an outer race and an inner race that can rotate relatively The seat ring is connected with the crawler car body by bolts, and the bottom end of the column 1 penetrates the inner race and is connected with the inner race by bolts.

The guide rail 2 is horizontally connected to the column 1, and the power head 3 is parallel to the guide rail 2.

The slewing reducer is a full-circle slewing speed reduction transmission mechanism integrated with a driving power source. It uses a slewing bearing as a drive follower and a mechanism attachment, making it a combination of slewing, deceleration and driving functions. It is a general-purpose deceleration transmission mechanism with simple structure and convenient manufacture and maintenance.

The rotary reducer 4 can drive the inner race to rotate relative to the outer race, thereby driving the column 1 to rotate axially, and then driving the guide rail 2 and the power head 3 to rotate 360° in the horizontal direction, realizing the angle adjustment of the power head 3 in the horizontal direction . Therefore, by adding the rotary reducer 4, the power head 3 can be adjusted in the horizontal direction. Improve work efficiency.

The above description is only the preferred implementation mode of this patent. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of this patent, some improvements and replacements can also be made. These improvements and replacements It should also be regarded as the scope of protection of this patent.

Claims (2)

1. A drilling rig with a rotatable column, comprising a crawler car body, a column is vertically arranged on the top of the crawler car body, a guide rail is arranged horizontally on the column, and a power head is arranged on the guide rail, and it is characterized in that : The top of the crawler car body is vertically provided with a slewing reducer with a slewing bearing, and the slewing bearing includes an outer race and an inner race that can rotate relatively under the drive of the slewing reducer, and the outer race It is connected with the crawler car body through bolts, and the bottom end of the column penetrates into the inner race and is connected with the inner race through bolts. 2.
