Problems solved by technology

[0002] At present, most coal-rock and semi-coal-rock roadways have gas or water permeation accidents. Before the roadheader cuts, it is necessary to drill holes for gas and water on the roadway section. The general working condition is manual drilling by workers, which is time-consuming and laborious. To solve the above problems A drilling rig integrating the drilling rig and the roadheader is proposed. The oil passage of the roadheading machine is used to realize the automatic drilling of the drilling rig and reduce the labor force of the workers. However, this kind of drilling machine has the problem of small drilling range.

Embodiment 1

[0049] Such as Figure 5 As shown, in addition to the features described in the above embodiments, it is further defined that: the first rail 121 extends along the length direction perpendicular to the excavation portion 11 . In this way, in the case of the same track length, the distance from the first track 121 to the excavation part 11 is the largest, so that the drilling machine part 13 can obtain a larger drilling range in the left and right directions.

Embodiment 2

[0051] Such as Figure 5 and Figure 6 As shown, in addition to the features described in any of the above embodiments, it is further defined that: the first track 121 includes an arc track or a straight track. In this way, the movable range of the drilling machine part 13 on the vertical height is further increased by the arc-shaped track, and then the drilling height of the drilling machine part 13 is increased, and the arc-shaped track design makes the motion track of the drilling machine part 13 roughly arc-shaped, which is more suitable. It is suitable for the construction environment where arches are required, such as roadways.

[0052] Of course, the first track 121 can also be set to include a straight track, so that the sliding of the drill unit 13 on the straight track is smoother and more stable.

Embodiment 3

[0054] Such as figure 1 As shown, in addition to the features described in any of the above embodiments, it is further defined that: the first track 121 is connected to the cutting arm 112 and is located on the cutting arm 112 close to the cutting head 111 . Make the drilling machine part 13 closer to the front side of the complete machine, further expand the drilling depth of the drilling machine part 13.

[0055] Further, as figure 1 and Figure 4 As shown, the slide rail assembly 12 includes a mounting bracket 129 , one end of the mounting bracket 129 is connected to the first rail 121 , and the other end is disposed on the cutting arm 112 close to the cutting head 111 .

[0056] For example, the mounting bracket 129 includes support rods arranged at the left and right ends of the first rail 121. Preferably, the mounting bracket 129 and the first rail 121 are fixedly connected by screw fasteners, wherein the support on the left side The rod is connected to the left side ...

Abstract

The invention provides an excavating and drilling machine which comprises an excavating part, a sliding rail assembly and a drilling machine part, wherein the excavating part comprises a cutting arm and a cutting head positioned at the front end of the cutting arm and connected with the cutting arm; the sliding rail assembly is mounted on the cutting arm, and comprises a first rail; an inclined angle is formed between the first rail and the excavating part; and the drilling machine part is connected with the first rail in a sliding manner, and slides along the first rail to be enabled to moverelative to the excavating part. According to the excavating and drilling machine provided by the invention, the drilling machine part slides along the first rail, so that the drilling machine part moves relative to the excavating part; the degree of freedom of the movement of the drilling machine part relative to the excavating part is released through the first rail, for example, the first railspans the left side and the right side of the excavating part, so that the drilling machine part can move between the left side and the right side of the excavating part; and compared with a scheme that an existing drilling machine part only depends on the movement of an excavating part to move, the drilling machine part in the scheme is more flexible, and the drilling range of the drilling machine part is further increased.

Description

technical field [0001] The invention relates to the field of drilling machines, in particular to a drilling machine. Background technique [0002] At present, most coal-rock and semi-coal-rock roadways have gas or water permeation accidents. Before the roadheader cuts, it is necessary to drill holes for gas and water on the roadway section. The general working condition is manual drilling by workers, which is time-consuming and laborious. To solve the above problems A drilling rig integrating the drilling rig and the roadheader is proposed. The oil passage of the roadheading machine is used to realize the automatic drilling of the drilling rig and reduce the labor force of the workers. However, this kind of drilling machine has the problem of small drilling range. Contents of the invention [0003] In order to solve at least one of the above technical problems, an object of the present invention is to provide a drilling machine. [0004] In order to achieve the above obje...
