TECHNICAL FIELD
[0001] The present application belongs to the technical field of underground roadway tunneling operation equipment, and particularly relates to a slippable drilling and anchoring device which can temporarily support the empty roof area in front of the tunneling equipment, effectively perform permanent support operation on the just-exposed roof and two sides in the tunneling roadway, and balance the relationship between tunneling and support without interference between roadway cutting operation and support operation, and has wide application range and high operation safety. BACKGROUND
[0002] At present, the coal roadway tunneling equipment in underground coal mines mainly includes a tunneling machine and a tunneling and anchoring integrated machine. The ordinary tunneling machine itself does not have a drilling and anchoring device, so after tunneling a step distance, the tunneling machine needs to retreat and stop, and then an operator manually holds an anchor rod drilling machine to perform permanent support on the exposed roadway. This operation mode is low in efficiency and poor in safety. The existing tunneling and anchoring integrated machine mostly adopts a horizontal shaft cutting part, can realize full-face cutting, and thus makes the roadway one-time formed, and the tunneling and anchoring integrated machine itself is also equipped with multiple anchor rod drilling machines, which can ensure simultaneous tunneling and support operation, greatly improving the tunneling efficiency and safety.
[0003] However, the existing structure of the tunneling and anchoring integrated machine has a problem that the distance from the front row of anchor rod drilling machines to the head position is greater than 3 meters, that is, there is always more than 3 meters of empty roof in the tunneling head. This empty roof condition is not a problem when the roof condition is good; however, once the roof condition is slightly broken, the anchor rod drilling machines configured in the tunneling and anchoring integrated machine cannot be used, and only manual drilling machines can be used to perform support operation at the tunneling head position in the empty roof state. Not only the tunneling efficiency cannot keep up, but also this passive manual support operation is more dangerous than the manual support operation using the ordinary tunneling machine. Therefore, although the tunneling and anchoring integrated machine has high tunneling efficiency, its applicable conditions are limited, and it is only suitable for use in the tunneling roadway with a complete roof. Therefore, it is necessary to improve the on-board drilling and anchoring device of the existing tunneling equipment. SUMMARY
