Example Embodiment

[0060] Example 1:

[0061] This embodiment provides a foldable bolt drill that can perform circumferential rotation and porous construction, including a base part, a circumferential hole forming part and a two-stage folding part, both of which are carried on the base part. The circumferential hole forming part includes a first The circumferential hole forming part and the second circumferential hole forming part are located on two sides of the base part; the two-stage folding part includes a first two-stage folding part and a second two-stage folding part, which are located on the other two sides of the base part; The first circumferential hole forming part and the second circumferential hole forming part have the same structure and are arranged at intervals; the first two-stage folding part and the second two-stage folding part have the same structure and are arranged at intervals;

[0062] The first circumferential hole forming part or the second circumferential hole forming part...

Example Embodiment

[0075] Example 2:

[0076] This embodiment provides a folding bolter drill that can perform circumferential rotation and multi-hole construction, mainly using different types of cylinders, rack and pinion mechanisms, gear meshing parts, fixed pins, slewing support mechanisms, grading platforms, slide rails, etc. The structure realizes the two-level folding function and the translation feed function. This device mainly includes the following parts:

[0077] The first part is the base part. It is composed of a crawler wheel 19, a chassis, a base 17, a bottom slewing support platform 18, and a driving gear. The track wheels 19 and the chassis are connected by axles and bolts; the slewing support platform 18 at the bottom is fixed on the base 17 and the chassis by bolts and nuts; the driving gear of the lower part of the side plate 9 is fixed by bolts on the base. The crawler wheel 19 is responsible for the translation and feeding operation of the bolt drill; the slewing support pla...

Abstract

The invention provides a folding roof bolter capable of carrying out circumferential rotation for multi-hole construction. The folding roof bolter comprises a base part, circumferential holing parts and two-stage folding parts. The circumferential holing parts are located on two sides of the base part. The two-stage folding parts are located on the other two sides of the base part. Each circumferential holing part is provided with a holing part and an axial rotation mechanism, wherein the axial rotation mechanism is used for making the circumferential holing part to axially rotate to be at thesame horizontal plane as the two-stage folding parts, and the holing part is used for smooth feeding drilling in the horizontal plane or a horizontal plane where the circumferential holing part is located on before or after axial rotation. The two-stage folding part is used for implementing inclined drilling. With the folding roof bolter capable of carrying out circumferential rotation for multi-hole construction, it is solved that a drilling equipment in the prior art cannot make anchor holes be in the same straight line, and cannot meet the requirements of construction for large, medium, small and narrow roadways either.

Description

technical field [0001] The invention belongs to the field of drilling in tunnel support work in coal mines, and in particular relates to a folding bolt drilling rig which can be rotated around a vehicle body in a seamless circumferential direction for porous construction. Background technique [0002] In the coal mining process, in addition to some tunnel drilling operations in the underground, coal mine roadway support work is also required. Affected by my country's coal storage geological conditions and coal seam characteristics, as well as the differences in the construction conditions of different coal mines, it is necessary to meet different needs for individual design, so that it can not only realize tunnel drilling, but also perform porous construction at the same time, greatly improving the performance of rock bolters. The construction efficiency is high, which is also the development direction of the future rock bolter. The safety situation of coal mines in my count...
